I EXECUTIVE SUMMARY

A. Introduction

1. The Project will construct a 58 kilometer expressway between Ben Luc and Long Thanh in the south of Ho Chi Minh City (HCMC), which is a short link of the GMS Southern Economic Corridor, to improve transport efficiency. The executing agency is the Vietnam Expressway Corporation (VEC), which was established under the Ministry of Transport (MOT) to develop national expressway network in Viet Nam. The project will be co-financed by the Asian Development Banbk (ADB) and Japan International Cooperation Agency (JICA). The objectives of this EIA report are as follows.

(i) Describe aspects and activities related to the design, construction and operation of the Ben Luc-Long Thanh Expressway Project (the project), which may cause positive and negative impacts on the natural and socio-economic environment.

(ii) Establish the main characteristics of the natural and socio-economic environment at the project area (7 districts where the expressway will pass across). The major environmental components are wetland ecosystem, land, aquatic, air and noise environment.

(iii) Predict and assess potential impacts on the physical, biological and socio-economic environment, caused by wastes and non-waste sources during various phases of the project: pre-construction, construction and operation. For each negative impact, corresponding mitigation measures have been formulated for implementation.

(iv) Prepare an Environmental Management Plan (EMP), including environmental mitigation measures and monitoring activities, capacity building program, public involvement and cost estimation for implementation.

2. This EIA study was implemented in 7 districts, but mainly in a corridor within about 250m of each side of the project alignment. The main environmental components (physical, biological, socio-economic aspects) related to project activities and impacts were considered in this study. 3. To predict and assess the potential impacts, various methods in EIA were used: checklist, matrix, public consultations, site observations, review of project design, air quality and noise modeling. The standard methods for collection and analysis of environmental samples were applied. 4. This EIA report contains the following chapters: I. Executive Summary II. Policy, Legal and Administrative Framework III. Description of the Project IV Description of the Environment (Baseline Data) V. Anticipated Environmental Impacts and Mitigation Measures VI. Analysis of Alternatives VII. Information Disclosure, Consultation and Participation VIII. Grievance Redress Mechanism IX. Environmental Management Plan X. Conclusion and Recommendations References

Because this project is supported by the Asian Development Bank (ADB) under ADB TA 7155-VIE "Preparing Ben Luc - Long Thanh Expressway Project", the EIA report follows the ADB Safeguard Policy Statement (June 2009). 7. In this EIA the following documents of the Government, Ministry of Transport and local authorities related to the Project are also considered.

(i) Decision 1724/QĐ/TTg dated 01 December 2008 by the Prime Minister on approving the Master Plan of Highways System in Viet Nam until 2020.

(ii) Decision 101/2007/QD/TTg dated 22/01/2007 by the Prime Minister on approving the Master Plan of Traffic Development of Ho Chi Minh City until 2020 including Ben Luc – Long Thanh Expressway.

C. Description of the Project

8. The project includes:

(i) Construction of an expressway with a length of 58 km and a a width of about 73 m connecting Ben Luc district of Long An province in the Mekong Delta to Long Thanh district in the Southeastern Region. This expressway will go across the southern districts of Ho Chi Minh City (HCMC): Binh Chanh, Nha Be, Can Gio, where at present there is no highway.

(ii) Construction of over 20 bridges, in which 2 large-sized bridges are Binh Khanh over the Soai Rap river and Phuoc Khanh over the Long Tau river.

(iii) Construction of auxiliary technical facilities along the expressway. 9. The operation of the expressway will create significant socio-economic effects for HCMC, provinces in the Mekong Delta and Southeastern regions. 10. The construction of the expressway is planned to commence in early 2012 and to be completed by the end 2016.

D. Description of the Environment

11. From the primary data obtained by field survey and environmental analysis by the EIA consultants and secondary data collected from various central and provincial agencies the following present state of the environment at the project area has been clearly identified.

1. Climate

12. Within the project area there are two distinct seasons: dry season and rainy season lasting from December to April the following year. In the last months of the rainy season (September-November) floods occur, placing constraints on construction of the expressway in flat lowland areas. With the increased impacts caused by climate change the project should include adaptation strategies for climate change in the design to accommodate the expected rise of sea water level in the Dong Nai - Saigon river estuary region. Detailed data on climate at 3 Meteo – Hydrological stations located closely to the project area are given in Chapter II of this EIA Report.

2. Hydrology

13. There are over twenty large and small rivers and canals crossing the project alignment. They are main waterways and sources of water supply for aquaculture. There are no canals or rivers used for domestic water supply. A semi diurnal tidal regime is dominant in this region. The river flow depends on the season: it is very high at the end of the rainy season and low at the end of the dry season. Floods sometime occur at some canals and rivers in the Western part of the project area.

3. Soils and Sediment

14. Seven soil classes are found in the project area. The soil map prepared by the EIA Team indicates that acid sulphate soils (ASS) occupy over 30% of the total land area of the project districts. ASS are mainly distributed at the Western and Central sections (Ben Luc, Binh Chanh and Can Gio districts). Saline solids are commonly distributed in Can Gio and part of Nhon Trach, Long Thanh districts. Earthworks at acid sulphate and saline soil areas may cause adverse impacts on the local soil and canal, pond water quality. 15. The analytical data of samples collected at 12 sites in May and August 2009 indicated that at present, there is not significant soil and/or sediment contamination by heavy metals, but grease and oil contamination is found in sediment of the canal and rivers at the project area.

4. Water Quality

16. River and canal water at all 12 monitoring sites were contaminated by organic matter, nutrients, bacteria and oils at slight (at the large rivers) and medium (at canals and small rivers) levels. There are no rivers which meet the Vietnamese National Technical Regulation for Source A of Surface Water Quality (QCVN 08:2008/BTNMT). The main water pollution sources are urban wastes (at the canals, rivers in the Western sections) and by industrial wastes (at the rivers and canals in Eastern sections). Problems of pollution caused by toxic chemicals (heavy metals and pesticides) are not found. At present, due to high salinity and/or high pollution by organic matter, turbidity, oils and bacteria, water of all rivers and canals in the project districts are not used for domestic water supply. However, the expected increased water pollution

4

caused by turbidity, oil, organic matters at some canals caused by road and bridge construction may impact local aquaculture. 17. Groundwater at the monitoring sites is slightly contaminated by bacteria and salinity. However, water of most of the monitored wells may be used for domestic water supply.

5. Air Quality, Noise and Vibration

18. At present, air and noise pollution is evident at the monitoring sites at the existing highway or provincial roads. Dust concentration exceeded the permissible limit in the Vietnamese National Technical Regulation for Ambient Air Quality (QCVN 05:2009/BTNMT). Noise levels vary from 65 to 75 dB(A), exceeding the permissible level for residential areas (TCVN 5949:1998). This problem does not occur at the sites located at the field or rural areas far from the existing roads. Levels of SO2, NOx or CO at all monitoring sites were within the standard. Vibration at most sites is within permissible levels.

6. Aquatic Ecology

19. Characteristics of the aquatic habitats at the rivers and canals in the project area were determined by the results of aquatic organism analysis in May and August 2009. The study has clearly identified 3 aquatic ecological zones depending on water salinity (fresh, brackish and saline) occurring at the canals and rivers in the project area. Various biological indices were used for evaluation of biodiversity of aquatic organisms. Lists of identified plankton species and their density, composition and density of benthic animals, composition of economic fish, shellfish, and shrimps were given in chapter IV of this EIA report. In 2009 the EIA study has identified 134 phytoplankton species, 28 zooplankton species, 18 benthic macro invertebrate species and 82 fish species. Composition and density of aquatic organisms vary greatly based on water salinity, water pollution and seasons. Biodiversity indices of the aquatic organisms at each site were determined. The obtained data indicate that no aquatic organisms species found are listed in the Vietnamese Red Book (2000).

7. Terrestrial Ecosystem

20. Based on the results of the field survey from May to August 2009 at the project (ROW), 8 common types of natural habitats at 6 sections in 7 districts of the project area were identified. The major habitats are paddy field, residential land, and canal and river corridors. Mangrove ecosystems are found mainly at the Thi Vai river in the Eastern Sections (in Long Thanh and Nhon Trach districts). At Binh Khanh Commune in Can Gio district, which is located in the transition zone of the Biosphere Reserve, there is no mangrove forest area but only a narrow belt of Nipa palm, Sonneratia spp. and mangrove brush trees. 21. Characteristics of the habitats with lists of vegetation and wild animal species at each of 6 sections along the project alignment were clearly identified. From the list of recorded (148 vegetation species and 19 wild animal species) it is observed that at present at the project area there are no vegetation and/or wild animals species listed in the Vietnamese Red Book.

8. Natural Protected Areas

22. Within a distance of 30km from the project alignment there is only one natural protected site: Can Gio Protected Mangrove Forest. This forest is included in the UNESCO Biosphere Reserve Network. Therefore, considerable attention has been given to this site during the EIA study. Various meetings with the governmental, city and district authorities were held to obtain

5

comments on the project impacts on this protected area. From the obtained information the following findings may be given. 23. The Can Gio Biosphere Reserve is divided into three zones as follows.

(i) Core zone occupies 4,721 ha covered the Southern part of Tam Thon Hiep, Western part of Thanh An and Northeastern part of Long Hoa communes with six sub-zones numbered 3, 4b, 6, 11, 12 and 13. Priority is given to use of the core zone for scientific studies, particularly studies into sustainability and ability of genetic biodiversity restoration.

(ii) Buffer zone occupies over 37,000 ha and covers the Northern part of Tam Thon Hiep, Eastern part of Thanh An, Eastern part of An Thoi Dong and Ly Nhon and Southwestern part of Long Hoa commune with 18 sub-zones and 3,800 ha of water. In this zone, only limited forest exploitation is permitted on the principles of preservation of resources, biodiversity and ecological balance. In fact, models of forestation together with aquaculture will be maintained in order to secure local people’s income.

(iii) Transition zone covers all areas of Binh Khanh commune, Western parts of An Thoi Dong, all Ly Nhon communes and all Can Thanh Town, with over 29,000ha of land and 570 ha of water. According to the information from the Can Gio Mangrove Management Board and the Section of Natural Resource and Environment of the district in this transition zone urban, industrial transport and other projects can be developed to meet the local and national economic demands. In this zone transport (highway, road, and port), agriculture, aquaculture, and urban development projects are permitted. These development projects are not forbidden by Ho Chi Minh City, Can Gio Mangrove Forest Management Board, the Forest Development Law of Vietnam and also by UNESCO’s Guidelines.

24. According to UNESCO Guidelines, in the transition zone of biosphere reserves, urban and industrial parks development to meet local and national demands are recommended. Therefore, development of the expressway in the transition zone of Can Gio Biosphere Reserve is widely accepted. 25. Binh Khanh commune, where the Project alignment will go through, is located outside of the mangrove forest. During the past 30 years there was no forest areas planted in this commune. At present, the commune is a main rice cultivation area of Can Gio district. The other parts of the commune area are used for aquaculture, port and residential sites. 26. According to the results of the field surveys conducted by the EIA Team in May – August 2009, in Binh Khanh the main vegetation species are rice and Nipa palm. Some thin belts of Nipa palm (Nipa fruticans), Sonneratia spp., and mangrove trees along the Nha Be, Long Tau rivers and canals occur. No forest was observed. There are some species of wild animals such as frogs, snakes, rats and birds which are occasionally found, but there is no species listed in the Vietnam Red Book. E. Anticipated Environmental Impacts and Mitigation Measures

27. In this chapter the following environmental impacts in 3 phases of the project implementation were clearly predicted and the countermeasures were suggested.

6

1. Impacted in the Pre-Construction Phase

a. Physical Environment

28. In the pre-construction phase impacts on the physical environment from land acquisition, resettlement, and site clearance are expected.

b. Biological Environment

29. The impacts of land acquisition and site clearance on the biological environment at 6 sections of the whole alignment were predicted and assessed. 30. At sections 1, 2, 3 (Ben Luc, Can Giuoc, Binh Chanh and Nha Be districts) the impacts on the natural ecosystems are expected as long-term but minor, due to most of the areas being agricultural and residential land and there is no area of forest and/or natural reserve in these sections. 31. At section 4 (Binh Khanh commune in Can Gio district), located in the transition zone of the Biosphere Reserve and about 10km from the boundary of mangrove forest most of the area is used for agriculture, aquaculture and residential sites. There is no mangrove forest in this commune but there are belts of Nipa palm and some mangrove brush trees along the canals, rivers and at the lowland. There are only some small and common wild animal species in this section. Therefore, impacts caused by land clearance on biodiversity in this section are expected as minor. 32. At sections 5 and 6 in Dong Nai province, the alignment goes across a large area of mangrove forest along the Thi Vai river. This forest is an important place for growth of mangrove trees, fish species, amphibian animals and aquatic birds. However, the project will construct two long viaducts to connect the two sections of Thi Vai bridge. Therefore, the area of mangrove forest to be cleared would be small. The impact on the local mangrove ecosystem is expected as minor. 33. In order to minimize the predicted impacts on the existing wetland ecosystems the following measures will be implemented in the pre-construction phase.

(i) Do not cut trees outside the project ROW. (ii) Do not dispose waste into forest and wetland area. (iii) Design and construct viaducts passing over the mangrove forest area at the Thi

Vai river banks. (iv) Properly implement the Mangrove Reforestation Plan (MRF) for replanting

mangrove trees to compensate the mangrove area lost by site clearance. Depending on topographical, water inundation, soil and water salinity the major trees to be replanted are Avicennia sp., Rhizophora spp. and Nipa palm.

c. Socio – Economic Environment

34. A total of 2,558 households will be affected by the project due to acquisition of residential land; 1,908 households will be affected by acquisition of agricultural and other lands. 35. Therefore, the project will cause major negative impacts on the project affected households (PAHs). The PAHs will lose income due to loss of agricultural and/or aquacultural

7

land. They will meet great difficulties in living restoration. Housing and social problems for the PAHs will be created. 36. To minimize the predicted socio-economic impacts to PAHs, a proper Resettlement Action Plan (RAP) prepared by the project and provincial PCs will be implemented.

2. Impacts and Mitigation Measures in the Construction Phase


37. Cutting and filling to construct road embankment will cause the main following impacts to the physical environment.

(i) Air (dust) and noise pollution: medium to major impacts. (ii) Canal and pond water pollution, caused by storm water containing solids, oils

and acidic materials (in acid sulphate soil area): minor to medium impacts. (iii) Land pollution caused by storm water containing oils, acidic materials (in acid

sulphate soil area): minor impact (iv) Water inundation at the upstream area of the embankment in the flooding season

if drainage system would not be properly installed. 38. Domestic waste water from construction worker camps, hazardous wastes and construction wastes may cause the following impacts on the physical environment.

(i) Air pollution by odor: minor impact. (ii) Canal and pond water pollution caused by organic matter, nutrients, solid, oil and

bacteria: minor to medium impacts. (iii) Land pollution by grease and oil: minor impact.

39. To minimize the potential impacts on the physical environment the following main measures will be implemented in the construction phase.

(i) Properly collect, segregate, transport and treat domestic, hazardous and construction wastes, generated at worker camps and construction sites.

(ii) Construct noise and dust control barriers (walls) at the sensitive receptors closed to construction sites.

(iii) Properly treat acidic storm water at acid sulphate soil area. (iv) Properly install culverts and drainage system connecting the upstream to

downstream areas to avoid water inundation at the upstream side. (v) Disposal of untreated wastewater is prohibited while disposal of solid wastes

shall only be to sites approved by local authorities.


40. During the construction phase the natural habitats would be continuously damaged by cutting and filling activities and encroachment of workers into mangrove forest area, mainly at the Thi Vai river banks. This impact is expected as minor, due to the mangrove area to be encroached being small. 41. Land pollution caused by storm water, domestic wastes from construction worker camps and construction wastes may damage natural vegetation and food crop species. This impact is assessed as minor.

8

42. Due to canal and pond water pollution by run-off water, particularly acidic run-off water and wastes from the construction sites, fish and shrimp species may be damaged. 43. To mitigate the potential impacts on the biological environment in this phase the following measures are suggested.

(i) Do not clear vegetation cover outside the project ROW. (ii) Do not dispose domestic, hazardous and construction wastes into land, field,

canals and rivers. (iii) Properly treat acidic water from construction site at acid sulphate soil areas. (iv) Replant mangroves to compensate the area lost by cutting and filling activity.

c. Socio - Economic Environment

44. During the construction phase various negative impacts on the local socio-economic are expected.

(i) Conflicts between workers with local residents due to differences in customs and cultural: minor impact.

(ii) Transmission of epidemic diseases from workers to local residents and vice versa: minor impacts.

(iii) Adverse impacts on business and living conditions of local residents due to movement of construction machines, causing air (dust), noise pollution, damage of local roads, traffic accidents, and water pollution effecting on of aquaculture: medium impact.

45. To mitigate the predicted socio-economic impacts the following measures will be implemented.

(i) Proper management of labor force, so that workers maintain a good relationship with the local community.

(ii) Hire qualified locals during construction, as much as possible. (iii) Coordinate with local PCs to promote awareness of both workers and local

residents on prevention of HIV/AIDs, epidemic diseases such as water-borne and vector-borne diseases, and other related diseases.

(iv) Implement identified mitigation measures to minimize impacts on air quality, noise, water quality, etc. caused by project-related activities.

3. Environment Impact and Mitigation Measures in the Operation Phase


46. Air dust, NOx, CO, SOx pollution caused by increased traffic activity will rise. However, the results of the air quality modeling indicate that dust, SO2, NOx, CO concentrations generated by the predicted volume of vehicles in 2036 would not exceed the permissible limit of the Vietnam National Technical Regulation for Ambient Air Quality (QCVN 05:2009/BTNMT) and IFC (WHO) Guideline for Ambient Air Quality. Only in cases of cumulative impacts (combination of the existing concentration of air pollutants to the increased level of air pollutants created by the increased traffic facilities), dust and SO2 concentrations at some sites would exceed the permissible limits. CO pollution would not be a problem in the future on this expressway.

9

47. Noise pollution caused by the increased volume of vehicles will be a major impact. Noise pollution modeling indicates that in 2036, without noise control barriers, noise levels up to within 300m from the road centerline will exceed the Vietnamese and IFC (WHO) permissible limit for sensitive receptors (hospital, office, schools etc.) in daytime and nighttime. 48. Water and land contamination caused by storm water from road surface would be minor.


49. During operation of the expressway direct impacts on vegetation and aquatic species are expected as minor.

c. Socio – Economic Environment

50. In this phase some impacts on the socio – economic environment were predicted in the EIA report.

(i) Promotion of urbanization, industrialization, trade and tourism in the Mekong River Delta and Southeast regions, improving living conditions, income, education, women roles and poverty alleviation for local people. It is major positive impact of the project.

(ii) Increase or decrease of traffic accidents, depending on traffic management. (iii) Separation of communities due to the physical barrier created by the

expressway.

d. Induced Development

51. With the expansion of urban, industrial and tourism areas created by the expressway and other projects, it is expected that the area of natural habitats in Ho Chi Minh City, Dong Nai and Long An Provinces would be reduced, causing various environmental and social impacts. Air, water, land pollution caused by the increased amounts of municipal and industrials wastes would rise. 52. These impacts are expected as medium to major depending on the implementation of the National Strategy for Environment Protection and the policies in sustainable development of local provinces/ ministries. However, these impacts will not be caused by this single project, but even without the project, they will be created by planned and ongoing regional urbanization and industrialization.

e. Impacts Caused by Climate Change

53. The main consequence of climate change in the region of project’s districts is rise of sea water level. With the high embankment of the expressway and provision of adequate drainage system, the impact of seawater rise on this project is expected as minor.

f. Mitigation Measures in the Operation Phase

54. To minimize the predicted negative impacts in the operation phase the following measures shall be implemented.

(i) Setting up residential, commercial areas within the safety corridor shall not be not allowed.

10

(ii) Construction of sensitive receptors (hospitals, schools, temples, churches within 300m from the road, shall be avoided, as much as possible if noise barriers will not be set up.

(iii) Construct noise barriers at the sensitive receptors located close to the expressway if it will be required by local residents.

(iv) Construction of frontage roads, underpasses and overpasses to provide access across the expressway

(v) Proper traffic management (vi) Installation of traffic sign boards and regular road maintenance. (vii) Provision of vegetation cover where it is possible along the expressway. (viii) Provision of sanitation facilities at rest stations. (ix) Implementation of the environmental monitoring plan. (x) Implementation of laws, policies in environmental protection, biodiversity

conservation, forest protection and National Plan for Environmental Protection during the growth of urbanization and industrialization in the region.

(xi) Proper design, construction and maintenance of the road embankment to prevent damage due to seawater rise and flooding

F. Analysis of Alternatives

55. In this study various alternatives were analyzed based on points of view of social and environmental impacts.

1. Do nothing option:

56. If the expressway is not built a major link connecting regional economic development with the national highway network will be missing: “Do nothing” is not an option.

2. With the project:

57. In this option various alternatives in bridges or tunnels and 3 alternatives of alignment were analyzed.

(i) Alternative 1: which crosses the Soai Rap river again between the 220kV and the 500kv power-lines then crossing the Long Tau river. This alternative avoids encroachment into a lot of national economic works, dense populated areas and historical sites.

(ii) Alternative 2: enters Phu Xuan commune and crosses the Nha Be river. This alternative may encroach on various populated areas and large-sized national economic facilities.

(iii) Alternative 3: enters Phu Xuan commune but runs North of Alignment 2 then crosses the Nha Be river. This alternative also encroaches on many dense populated areas.

58. Carefully considering all alternatives the project has selected Alternative 1 of alignment and alternative of bridge construction for the feasibility study (F/S). G. Information Disclosure, Consultation and Participation

59. In this EIA two (2) types of public consultation have been implemented to comply with both Vietnam's and ADB requirements.

11

1. Public Consultation Process Following the Vietnam Guideline

60. The Law on Environmental Protection (2005) strongly requires public consultation and information disclosure on the project to local people prior to its commencement. The Circular 05/2008/BTNMT issued by Ministry of Natural Resource and Environment (MONRE) requires that the project owner should organize meetings with and obtain comments on environmental impacts and mitigation measures of the project from 2 organizations: People’s Committee (PC) and Fatherland Front Committee (FFC) of each commune where the project is located. PC is an administration agency and FFC is a political - social association, representative of local residents and other public associations. In case the project could cause serious potential impacts, meetings with local residents are also required. 61. To comply with public consultation and information disclosure requirements of ADB, the EIA Consulting Team of the Ben Luc - Long Thanh Expressway Project has conducted the following activities.

2. Public Consultation Process Following the ADB's Guideline

62. ADB strictly requires implementation of public consultation and information disclosure during the conduct of EIA study. This requirement is specified in ADB's Safeguard Policy Statement (2009). 63. The public consultation following ADB’s requirement was implemented in 2 rounds:

(i) First round: in the EIA preparation process: Interview of about 50 PAHs (by random selection) in 7 project's districts by filling questionnaire sheets to obtain information on their actual social and economic conditions and their comments on environmental issues of the project.

(ii) Separate meetings with 15 commune’s PCs and 15 commune's FFCs to a) - present a summary on the project description, impact assessment, mitigation measures and environmental management plan; b) obtain from them data/ information on the present socio-economic status of each commune; c) obtain from them letters on comments and suggestions on environmental impacts and mitigation measures of the project.

(iii) Second round: after preparation of Draft EIA report: Organization of 6 meetings with participation of 497 PAHs at 6 representative communes to obtain comments (by filling questionnaires on environmental issues and mitigation measures) and answer to them their questions on environment issues.

64. The obtained 500 questionnaire sheets filled by almost 550 PAHs (in 2 rounds) and 30 official letters from 15 PCs and 15 FFCs of 15 project communes indicated that all representatives of 15 communes and most of PAHs support the project implementation. However, most of them strongly require the project owner/ contractors to properly implement the following main measures.

(i) Good policies in compensation and resettlement for PAHs. (ii) Proper management of labor force and good construction management. (iii) Proper control of dust, noise, air, water pollution during road and bridge

construction. (iv) Do not fill up canals, water drainage systems. (v) Proper management of transport activities to avoid accident and road damage.

12

65. The project owner accepted all comments and requirements from PAHs and local PCs, FFCs and promised to implement appropriate measures to mitigate the negative social and environmental impacts caused by the project activities. H. Grievance Redress Mechanism

66. In this EIA a Grievance Redress Mechanism (GRM) was set up with the following contents.

(i) Introduction (ii) Definition of GRM (iii) Principles of Good GRM (iv) Proposed GRM for Environmental Performance for the Project (v) Identification of stakeholders in GRM for this project (vi) Legal guidelines of Vietnam on grievance redress (vii) ADB requirements in GRM (viii) Project potential impacts and types of grievance (ix) Mechanism of grievance redress applied for this project

67. This grievance mechanism is based on the Vietnamese legal framework as well as the ADB Policy. This redress mechanism will be easily applied by local residents, governmental agencies, project owner and contractors because it complies with the following requirements.

(i) Provides a predictable, transparent, and credible process to all parties, resulting in outcomes that are seen as fair and effective.

(ii) Builds trust as an integral component of broader community relations activities. (iii) Enables more systematic identification of emerging issues and trends, facilitating

corrective action. I. Environmental Management Plan (EMP)

68. In this EIA a comprehensive EMP was suggested in order to prevent and address negative impacts caused by Ben Luc - Long Thanh Expressway. The project owner, its contractors and the related authorities will implement this EMP. 69. The EMP is an integral part of the EIA. The EMP has been prepared to document the environmental management commitments and obligations that will be implemented throughout the pre-construction, construction and operation phases of the project. The EMP identifies the commitments and obligations, determines the responsibilities and timing for implementation and provides detailed costs estimates for implementation. 70. The EMP is structured as follows:

(i) Section IX. A contains a summary of the environmental impacts of the Project and description of environmental mitigation measures.

(ii) Section IX. B contains description of the planned mitigation measures in 3 phases of the project: pre-construction, construction and operation. This description includes project activities; potential negative impacts; responding mitigation measures; location and responsibilities of relevant stakeholders.

(iii) Section IX.C contains description of the environmental monitoring program in terms of both environmental effects monitoring (i.e. environmental effects of the project in comparison to ambient environmental standards) and project

13

performance monitoring (i.e. compliance of the project with technical standards and EMP requirements for implementation of mitigation measures)

(iv) Section IX. D contains description of planned public consultation process. (v) Section IX. E contains a description of the Responsibilities and Authorities for

Implementation of Mitigation Measures and Monitoring Requirements. (vi) Section IX. G contains Environmental Monitoring Reporting System. (vii) Section IX. H contains recommendations on the Capacity Building Activities that

are required for key agencies involved in EMP implementation. (viii) Section IX.I contains a detailed description of technical facilities needed for

implementation of EMP and Cost Estimates for EMP implementation. 71. Environmental Mitigation Plan describes the impacts to be mitigated; proposed technical and management measures to minimize the impacts and activities to implement the mitigation measures, including how, where and when they will be implemented. Responsibilities for implementation and supervision of each mitigation measure were also identified. 72. The Environmental Mitigation Plan was prepared for 3 phases: pre – construction, construction and operation of the expressway. Table IX.1 in this chapter indicates measures to be implemented for mitigating negative impacts in the Pre – Construction Phase. 73. In the construction and operation phases various mitigation measures have been specified to address impacts on the physical, biological and socio-economic aspects. All these measures are feasible and will be implemented by the project owner, its contractors and relevant authorities. 74. There are three types of environmental monitoring to be undertaken for the Project as shown below:

(i) Environmental effects monitoring: conducted to assess the impacts of project activities in the pre-construction, construction and operation phases on ambient environmental quality (surface water, air, noise, land, aquatic organisms and terrestrial habitats). Monitoring location of monitoring sites, frequency, and parameters to be monitored and monitoring methods were clearly identified. Responsibilities of the project owner, project supervision consultant (PSC), and local authorities were determined.

(ii) Project performance monitoring: conducted to evaluate compliance of the project owner and contractors with the mitigation measures specified in the EMP.

(iii) External monitoring: conducted by an external expert on an annual basis to verify the monitoring information submitted by VEC to ADB.

75. This chapter also defines the reporting requirements, capacity building in environmental management and estimated cost for EMP implementation. J. Conclusions and Recommendations

76. From the results of environmental assessment indicated above, the following conclusions may be given. 77. The Ben Luc – Long Thanh Expressway Project plays a significant role in improvement of the transport system of Vietnam. It will contribute to the socio-economic development of the

14

Southeastern and Mekong River Regions. Therefore, the project is strongly supported by Ministry of Transport (MOT), the provinces and people in the project area. 78. From primary and secondary data collected in this EIA, the characteristics of the present state of the environment at the districts where the expressway will pass across are summarized below.

(i) The projects area is located in the downstream of the Dong Nai – Saigon river basin; most of the area belongs to wetland with soft, flat and low elevation land.

(ii) At present, water contamination is high at the canals and evident at the rivers where the expressway will go across. Fish populations are poor in species and density.

(iii) At present, at the national roads air and noise pollution is significant, but air quality, noise and vibration levels at most communes where the expressway will be constructed, still meet the Vietnamese Standards.

(iv) In the past most of the area was agricultural land and waste wetland. During the last 20 years, with the rapid urbanization and industrialization a large area was converted for urban, industrial, tourist and aquaculture development. Therefore, natural habitats, biodiversity of aquatic and terrestrial ecosystems were reduced.

(v) Within a distance of 30 km from the project alignment is the Can Gio Protected Mangrove Forest (official name given by Ho Chi Minh City PC) which was approved by UNESCO in 2000 to be included in the World Biosphere Reserve Network. This biosphere reserve is an important site for conservation of mangrove forests, protection of the environment, education in biodiversity and economic development to meet local and national demands.

(vi) The design and construction of viaduct for the expressway will not involve an interchange with the existing Rung Sac highway in Can Gio district. It will go over Binh Khanh Commune, located in Transition Zone of Can Gio Biosphere Reserve. In the past and at present, there is no area of mangrove forest in this commune. The alignment passes through the transition zone of the biosphere reserve. According to UNESCO in the transition zone of biosphere reserve the economic objective is to develop urban areas, industrial zone and economic development to meet the local and national demand. As such, the project alignment in Binh Khanh commune complies with the Vietnamese Laws and UNESCO Guideline. Therefore, it is supported by Ho Chi Minh, Can Gio PCs and Management Board of Can Gio Protected Mangrove Forest.

(vii) The area, where the large area of mangrove forest still occurs, is the Thi Vai river banks in Dong Nai province. The project has been designed to minimize impacts on mangroves in the area through construction of a viaduct in densely vegetated areas instead of a road embankment.

79. This EIA has identified adverse environmental impacts due to the project, most of which will be experienced during construction and are therefore, temporary in nature. During construction, communities in the vicinity of the construction site and access roads will be most likely affected by elevated levels of noise and dust emission. Pollution of water resources and the surrounding environment may occur due to earthworks, generation of construction and domestic wastes, disturbance of acid sulphate soils and other project-related activities. During operation, it is anticipated that noise levels at residential areas along the expressway are likely to exceed ambient standards. Exhaust emissions will also contribute to air pollution in the project area.

15

80. Proper and timely implementation of various provisions of the EMP in terms of mitigation measures, monitoring and capacity building will minimize adverse environmental impacts due project construction and operation. 81. To ensure that adverse impacts due to project implementation will be adequately addressed, the tender and contract documents for civil works for the entire project (ADB and JICA sections) shall include the EMP. Regular monitoring and reporting on the status of EMP implementation shall be undertaken to ensure that mitigation measures are implemented as required and to allow for formulation and implementation of corrective actions, as necessary.

II POLICY, LEGAL AND ADMINISTRATIVE FRAMEWORK

A. Project Background

82. The Ben Luc - Long Thanh Expressway (the project or the Expressway), which will be implemented by the Viet Nam Expressway Corporation (VEC), will consist of a Southern link of the planned Ho Chi Minh City (HCMC) Third Ring Road and an access link connected to the planned Bien Hoa - Vung Tau Expressway. In the Southern area of HCMC, East-West traffic is restricted due to lack of river crossing facilities, forcing vehicles into the center of HCMC. Construction of HCMC ring roads to establish connectivity with neighboring cities by expressway links is considered a high priority by the Government. In this regard, the expressway will have significant positive impacts on socio-economic activities in the cities and towns around HCMC, and also will improve traffic problems in the center of HCMC by diverting the through traffic to the Expressway. The expressway will be used as freight route to and from the HCMC river ports. The Nha Be, Soai Rap, and Long Tau rivers in the project area are used as navigation channels for large cargo ships accessing the HCMC’ river ports. Moreover, in the Prime Minister's Decision No. 1734 dated 1 December 2008, the expressway is identified as a part of the National North - South Expressway. The Mekong Delta area contains major agricultural fields which are capable of rice triple - cropping. Industrial parks are being developed in the project area. The expressway will be used as a freight route to transport food produced in the Mekong Delta to the rest of the country by land and maritime transport. 83. The East-West Highway is under construction and will direct traffic through near the center, from Highway 1A in the South - West of Ho Chi Minh to Hanoi Road just East of Sai Gon bridge. The Southern link of Ring Road No.2 will also serve to allow traffic to pass around the city using the existing Sai Gon South Parkway and the Phu My bridge, which has been constructed. This will link to the already designed Ho Chi Minh City - Long Thanh - Dau Giay (Long Thanh - Dau Giay) Expressway. 84. Operation of the Ben Luc - Long Thanh expressway will create the following socio-economic effects:

(i) Strengthening economic effects, promoting commercial activities of the port systems in the region, reducing traffic congestion and price of transportation.

(ii) Reducing the amount of time of transports from the Mekong River Delta to South- East Regions and vice versa, increasing effects of operating and decreasing fees for transports and customers.

(iii) Improving economic growth, contributing social benefits for the Southern areas of HCMC where road systems are poor with the density canals systems but lack of roads and bridges.

(iv) Contributing to socio-economic development of Southeast region and the Mekong River Delta.

85. As part of the Asian Development Bank (ADB) financed TA (ADB TA 7155-VIE), a team of consultants has been commissioned to prepare an Environmental Impact Assessment (EIA) report for the Project. The Project has been categorized by the ADB as a Category A project for which an EIA is required. This EIA has been prepared based on ADB’ Safeguard Policy Statement (SPS), issued in June 2009. The Project will be co-financed with the Japan International Cooperation Agency (JICA). 86. The structure of the EIA is as follows:

III DESCRIPTION OF THE PROJECT

A. Type of Project

102. The project is a class "A" expressway with a length of 58.0 km and a width of 73 m. According to ADB Safeguard Policy Statement (2009) this project is classed as category A project and requires the preparation of an EIA Report. According to the Vietnam Guideline for EIA (Decision N 21/2008/ND-CP) this project belongs to the group of projects needing an EIA. B. Location of Project

103. The Ben Luc – Long Thanh expressway starts from the junction with the Ho Chi Minh City (HCMC) – Trung Luong Expressway at My Yen commune in Ben Luc district, Long An province and ends at the junction with the highway of Bien Hoa – Vung Tau at Phuoc Thai commune in Long Thanh district, Dong Nai province. The highway crosses 15 communes in 7 districts in 3 provinces (Table III.1).

104. Location map of project alignment in the traffic system of Ho Chi Minh City and surrounding areas is shown in Figure III.1. C. Need for Project

105. Ho Chi Minh City is the largest economic centre of Vietnam. The economy of Ho Chi Minh City annually contributes approximately 30% of Vietnam’s total GDP and contributes 25- 28% of total national budget. 106. The Southern Economic Focal Zones (SEFZ) (including Ho Chi Minh City, Dong Nai, Ba Ria - Vung Tau, Binh Duong, Binh Phuoc, Tay Ninh and Long An) have the highest growth in industrialization, urbanization and trade compared to other economic regions of Vietnam. Its annual GDP accounts for 40% of the total Vietnam GDP. There are many port systems in the zone, particularly port groups of Ho Chi Minh City, Cai Mep – Thi Vai and Dong Nai- Soai Rap.

24

107. Volume of goods through the port increased 15% per year (period 2005-2008). Owing to crowded population (7.9 million people in Ho Chi Minh City with the high physical population growth that could increase up to 10.3 million people in 2020) and the acceleration of industrialization, urbanization can cause overload of the traffic system of SEFZ, especially in Ho Chi Minh City. Connection between South-East provinces and South- West provinces (the Mekong River Delta) at present is mainly through National Road 1A (Bien Hoa- Ho Chi Minh City - Tan An). Going from planned Long Thanh International Airport to Ben Luc district (Long An) one has to pass through National Road 51, and National Road 1 with a total of 85 Km in length and usual occurrence of traffic jams. In addition, the Southern area of Ho Chi Minh City which borders Long An has numerous canal systems but there are no roads and bridges that connects the Mekong River Delta with Dong Nai and Ba Ria - Vung Tau. Therefore, the development of an expressway which connects Long An from a starting point of the Mekong River Delta with Long Thanh- in Dong Nai Province through the Southern districts of Ho Chi Minh City (Binh Chanh, Nha Be, Can Gio) and the Southern districts of Dong Nai (Nhon Trach, Long Thanh) is urgently needed. With this road, traffic distance between two regions is shorter by over 20 Km, decreasing traffic congestion at National Road 1A, 51, East-West highway and other roads passing through Ho Chi Minh City that contribute to the development of both South -East and South -West regions. D. Project Alignment Alternatives

1. Summary of Project Alignment

108. According to the master plan of traffic development of HCMC for year 2020 and after 2020 approved by the Prime Minister (Decision No. 101/QD-TTg dated 22/01/2007), the Ben Luc - Long Thanh expressway, one of six expressways at HCMC and surrounding areas, was proposed (Figures 1 and 2). This is an expressway class A with 120km/h designed speed. Project alignment was selected by the consultants after studying advantages and disadvantages of alignment alternatives as shown in Figure III.3. 109. To implement Traffic Master Plan for development of the North – South Expressway, Ministry of Transport (MOT) is preparing to invest in some of the expressways as HCMC - Trung Luong Expressway, Trung Luong - My Thuan - Can Tho Expressway, Ho Chi Minh City - Long Thanh - Dau Giay Expressway. 110. Running past HCMC, North - South Expressway will link to the Ring Road 3 (RR3). If the project alignment links to RR3 to the Western Region through Cu Chi district to Binh Duong province and Bien Hoa city, it will have an advantage on topography and geology, however, it will not have high efficiency to service the developing economic areas of Nhon Trach - Long Thanh, Thi Vai ports and Cai Mep ports at the Eastern Region. Therefore, the connection of the project alignment and the North – South expressway at HCMC to the Southern Region through Ben Luc to Nhon Trach will be consistent with the traffic master plan approved by the Prime Minister.

2. Detailed Description of Project Alignment

111. In general, the selected alignment of the project was approved by MOT and People’s Committees (PCs) of HCMC, Long An and Dong Nai provinces. Alignments at each province/city are described below.

26

a. Alignment in Long An Province

112. The alignment runs through Long An province from Km 0 – Km 10. The starting point is located in Ben Luc district on the HCMC-Trung Luong expressway and connects to RR No.3. From here the alignment goes to the South - East direction and crosses National Highway (NH) 1A at Km 3+400 where there are the least number of houses on both sides of the alignment (at Km1923+700 on NH1A). From Km 4 to Km 10, the alignment goes parallel with the administrative boundary between Binh Chanh and Can Giuoc districts. At Km 6 the alignment was adjusted to avoid the resettlement area that is under construction by the Five Stars International JSC (50m away from the right side of the alignment). Basically, the alignment proposed by Consultant has been agreed by Long An PC (letter No. 5414/UBND-CN dated 3rd November 2006). Total length within Long An Province is 4.6km including:

(i) Ben Luc district, L = 2.20km (ii) Can Giuoc district, L = 2.40km (iii) There is one interchange at HCMC - Trung Luong Expressway

b. Alignment in Ho Chi Minh City

113. In HCMC the alignment runs through Binh Chanh, Nha Be and Can Gio districts from Km 2+200 to Km 30+500.

(i) At Binh Chanh district: from Km 2+200 to Km 17+100 the alignment goes across Binh Chanh, Tan Quy Tay, Hung Long and Da Phuoc communes. The alignment is in accordance with the land use master plan of Binh Chanh District. The alignment was modified to avoid the Da Phuoc Waste Treatment Complex as requested by PC of HCMC (Letter No. 8197/UBND-DT dated 16th December 2005).

(ii) At Nha Be and Can Gio districts the consultants have studied three alternatives of river crossing locations.

i. Alternative 1 (South alignment alternative)

114. To overcome the disadvantages of the previous alignment studied by TEDI and JETRO, and avoid conflict with the water pipelines in Can Gio area district, avoid affecting the 500kV and 220kV electric transmission lines, Phu Huu 1 port and the existing dense residential area at Nguyen Van Tao street, the alignment runs on the right side and 120m away from the existing 500kV transmission line. There is an overlap of about 20m-30m of a project proposed by Vietnam Maritime Administration (from Km 22 to Km 23). However its master plan can be adjusted (Letter No. 517/UBND-PCT dated 16/6/2009 of People’s Committee of Nha Be District). Advantages of Alternative 1 over the other options are as follows:

(i) In accordance with HCMC master plan up to 2020 approved by the Prime Minister at the Decision No.101/QD-TTg dated 22 Jan. 2007.

(ii) The alternative has been agreed by the ADB TA 7155-VIE, MOT and HCMC Department of Transport as per the Notice No. 301/TB-BGTVT dated 30/6/2009 of MOT and Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC Department of Transport.

(iii) In accordance with comments from HCMC People’s Committee in letter No. 207/TB-VP dated 11 April 2006.

27

(iv) Avoids running between 500kV and 220kV transmission lines, which is very dangerous during construction as well as operation of bridges.

(v) Avoids the Phu Huu 1 Port as requested by Dong Nai People’s Committee at Letter No. 8156/TTr-UBND dated 01 Oct. 2008.

(vi) Does not impact on the master plan of Nha Be Area (vii) In accordance with the development master plan of HCMC. (viii) It is agreed by the Can Gio district PC in Letter N622/UBND dated 10 June 2009

and the Can Gio Protected Mangrove Forest Management Board (in letter N126/CV dated 29 July 2009).

Disadvantages

(i) There are two long high bridges with navigation clearance (about 250x55m). (ii) At weak soil area. (iii) The overhead transmission lines are visible from the bridge which does not

present an attractive view.

ii. Alternative 2 (North alignment alternative)

115. To avoid the disadvantages of alternative 1, alternative 2 runs to the North of alternative I crossing through Nhon Duc – Phuoc Kieng urban area (Km 20+800-Km 21+100), crossing the Muong Chuoi river at Km 21+500 and running overland to an internal road and Phu Xuan residential area (Km 21+900-Km 22+700), going in between of Techim Petrolimex and Sai Gon Metrolimex Store. However, the alignment of alternative III was not agreed to by DOT of HCMC of Nha Be district (letter No. 517/UBND-PCT dated 16/6/2009 of Nha Be PC and Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC DOT). Advantages of Alternative 2

(i) Construction site is easier than alternative I. (ii) Horizontal alignment is smooth. (iii) Only one long high bridge with navigation clearance required (about 300x55) at

the Nha Be river. Disadvantages

(i) The alignment runs through Nhon Duc - Phuoc Kieng urban area (which has been approved by HCM' PC).

(ii) May affect the future Phu Dong port. (iii) At weak soil area. (iv) Runs under the 500kV and 220kV transmission lines. (v) Affects many houses at the existing residential area (particularly at Huynh Tan

Phat street). (vi) Affects Phap Vo Pagoda (25m away from left side of the centerline).

iii. Alternative 3 (North alignment alternative)

116. To avoid the disadvantages of the above two alternatives, alternative 3 runs to the North of alternative I crossing through Nhon Duc – Phuoc Kieng urban area (Km20+800-Km21+100), crossing the Muong Chuoi river at Km21+500 and running avoided Phu Xuan residential area (Km22+00-km23+300), avoiding Phap Vo Pagoda, then going through Sai Gon Petrolimex Port. However, the alignment of alternative IIII was not agreed to by DOT of HCMC PC of Nha Be

28

district (letter No. 517/UBND-PCT dated 16/6/2009 of Nha Be PC and Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC' DOT).

Figure III.3: Location of Project Alignment and Interchanges (Selected Alternative)

31

Advantages of Alternative 3

(i) Construction site is easier than alternative 1. (ii) Horizontal alignment is smooth. (iii) Crossing at the narrowest location of the Soai Rap river (perpendicular with river)

so has the shortest crossing of the three alternatives. Disadvantages

(i) The alignment runs through Nhon Duc – Phuoc Kieng urban area, which has been approved by PC of HCM.

(ii) May affect the Master Plan of Port System at the other side of the river. (iii) At weak soil area. (iv) Affects many houses (particularly at Huynh Tan Phat street). (v) Affects Sai Gon Petrolimex port. (vi) Is not accepted by DOT of HCMC and PC of Nha Be district.

117. The Consultant (Katahira & Engineers International) - has presented in detail the alignment in HCMC to DOT of HCMC at the meeting on 03/June/2009 with the participants of the city agencies and departments and PCs of Binh Chanh, Nha Be and Can Gio districts. In general, the meeting has agreed to the alignment alternative 1 recommended by the Consultant (as per Notice No. 270/TB-SGTVT dated 09th June 2009). Total length of the alignment in HCMC is about 26 km (alternative) 118. Comparison on alignment options in HCMC section is presented in Table III.2 and Figure III. 4.

Table III.2: Comparison of Project Alignment Options at River Crossing Section

Alternatives Advantage Disadvantage

1. Alternative 1 - Avoid disadvantage of the previous studied alternatives that is causing effects on 500kV and 220kV power lines. - Avoid crossing Phu Huu 1 port as requested by Dong Nai PC (Letter No. 8156/TTr-UBND dated 1/10/2008) - Selected and agreed to by MOT and relevant agencies and departments of HCMC (Notice No. 301/TB-BGTVT dated 30/06/2009 of MOT and Notice No.270/TB-SGTVT dated 9/6/2009 of HCMC DOT) - Recommended by Nha Be PC (at Letter No. 517/UBND-PCT dated 16/6/2009 of Nha Be PC) - Has lower construction cost than other alternative.

- Two bridges should be constructed - Outlook of the bridge is less attractive than other alternatives.

2. Alternative 2 - The alignment is about 600m shorter than Alt. 1 - Only 1 large bridge to cross over Nha Be river required.

- The alignment breaks through Nha Be Planning area (not agreed by Nha Be PC at letter No. 517/UBND-PCT dated 16/06/2009)

32

Alternatives Advantage Disadvantage

- Construction cost of bridges is higher due to large bridge with long spans and long viaduct so as to cross over rivers and existing infrastructures. - Geometry of the alignment is better than Alt.1

- Affect the future Phu Dong port. - Run under the 500kV and 220kV power lines (may have to heighten electric poles) - Cross Phap Vo Pagoda. - Cross through the existing dense residential area in Huynh Tan Phat street. - Construction cost is higher than Alt.1 (due to having to construct large span viaducts to cross residential area, existing roads)

3. Alternative 3 - The alignment is about 500m shorter than Alt.1. - Crossing the Sai Gon river at the narrowest location. - Construction cost of bridges is higher due to large bridge with long spans and long span viaducts. - Geometry of the alignment is better than Alt.1

- The alignment breaks through Nha Be Planning Area (not agreed by Nha Be PC at letter No. 517/UBND-PCT dated 16/06/2009). - Crossing Sai Gon Petrolimex Store. - Crossing the existing dense residential area in Huynh Tan Phat street. - Construction cost is higher than Alt.1 - Running under the 500kV and 220kV power lines (may have to heighten electric poles). - Affecting the river port (Dong Nai side)

119. In Dong Nai province the alignment runs through Nhon Trach district (Km 30+500- Km 53+100) and Long Thanh district (Km 53+100-Km 58+500). The alignment avoids Phu Huu I port at Km 30+750 (as requested by Dong Nai PC) and running in parallel with the left side of 500 kV transmission line (away 130 m from the 500kV), crossing 500 kV and 220 kV at Km 32+000. From Km 32+000– Km 52+500 the alignment runs in between the right side of 110 kV and Nhon Trach outer road in accordance with Nhon Trach Master Plan as approved by the Prime Minister. The alignment avoids the Phuoc An port from Km 49+500-Km 52+500, crosses the Thi Vai river at Km 53+100, crosses NH51 at Km 57+500 and connects to future Bien Hoa -Vung Tau expressway by an interchange. 120. There are four tentative interchanges in Dong Nai province at: Inter-ports road (about km33), Nhon Trach city road, National Highway No. 51, Bien Hoa -Vung Tau Expressway.

3. Horizontal Alignment Design of Selected Alignment

121. The horizontal alignment was designed based on the Alignment 1 selected and agreed to by all the relevant authorities of Long An province, Ho Chi Minh City, Dong Nai province and by the Ministry of Transport.

a. Main Control Points and Outline of the Alignment

122. List of main control points and outline of the alignment is presented in Table III.4.

35

b. Description of the Alignment

123. Main features of the sections along the alignment are described as follows:

(i) From the starting point at Ho Chi Minh City – Trung Luong expressway, the alignment runs from West to East, crossing NH 1A at Km 3+400 (around Km1923+850 on NH1A Binh Chanh commune of Binh Chanh district) where there is only a few houses and utility works, (on the right side of the alignment is Phu Trieu Shoes Company), then goes parallel with the border between Binh Chanh and Can Giuoc districts.

(ii) From Km 5+800 – Km 6+300, the alignment is designed to avoid the Phuoc Ly resettlement area on the right side under construction (60m distant) in Phuoc Ly Commune, Can Giuoc district.

(iii) From Km 8+200-Km 8+700 the alignment crosses a residential area and Hai Son Industrial Zone in Long Thuong commune, Can Giuoc district (as the expressway is designed based on many control points, it is not possible to avoid this area), then crosses Doan Nguyen Tuan street at Km 9+200, avoids Pho Quang Pagoda on the left side of the alignment at Km 9+500, the alignment runs towards the East to cross over the Ong Keo river at Km 12+700 and crosses NH 50 at Km 13+500 (around Km 9+400 on QL50 Binh Chanh district).

(iv) From Km 14+700-Km 16+700 the alignment runs on the right side and 60m away from the Da Phuoc Waste Treatment Complex in Da Phuoc commune, Binh Chanh district crosses the Ba Lao river at Km 17+100, avoids the Nhon Duc Cemetery on the left side of Km 17+300 by 50m. The alignment goes through and in accordance with the master plan of Nha Be district, crosses North-South road (Nguyen Van Tao road) at Km 21+900 and runs parallel on the South and about 120m away from the 500kV power line, crosses over the Soai Rap and Long Tau rivers at Km23+500 and 30+400.

(v) From Km 24+000 – Km 30+000 (6km) the alignment runs through transition zone of Can Gio Biosphere Reserve, however, due to high distance (about 10km from the mangrove forest area the project activities will not cause impacts on the protected mangrove forests. This is determined by the Can Gio PC and Management Board of Can Gio Mangrove Protected Forest (Notice 622/UBND dated 10/6/2009 and Letter N 126/CV BQL dated 29/7/2009).

(vi) The alignment runs under the 500kV and 220kV power lines at Km 32+000 to go on the right side of 220kV power line and runs in accordance with Nhon Trach Master Plan approved by the Prime Minister (Km 38 to Km 49), from Km 49+400 – Km 52+700 the alignment runs avoiding the Phuoc An Port logistics area on the right side and also avoiding the Ba Truong Temple at Km 49+100 on the left side.

(vii) The alignment crosses the Thi Vai river at Km 53+050, then crosses NH51 at Km 57+600 (Km 35+350 on NH51) and then connects to the planned Bien Hoa-Vung Tau in Phuoc Thai Commune, Long Thanh District, Dong Nai Province.

commune, Long Thanh district. The alignment ends at the intersection point with NH 51 and connects to the planned Bien Hoa – Vung Tau expressway at Phuoc Thai commune under Long Thanh district, Dong Nai province.

c. Horizontal Alignment Design

124. The geometric elements of the alignment are designed based on Vietnamese Standard TCVN 5729-97. The Ben Luc - Long Thanh Expressway is a class “A” expressway with a design speed of 120km per hour because of the daily traffic volume. The centerline of the road is designed to be located at the Central Reserve for the completion phase. At the location of large

38

cable-stayed Binh Khanh and Phuoc Khanh bridges, the Phase 1 bridge structure will be constructed at centre-line with emergency lane.

There are in total 13 curves on the whole alignment, one with a minimum radius of 1,000 m at the interchange point with NH51. The remaining radii are from 2,200m to 18,000m. With the curve radius of more than 10,000 m and small deviation angle, it is considered necessary to have a transition curve (with those curves, function of transition curve is not efficient).

4. Vertical Alignment Design

126. The finished grades of the highway having medians will be defined at centerlines edges of the pavement and controlled by the following:

39

(i) Elevation system used for the project is the Vietnamese National Elevation System with Hon Dau’s Level. Existing ground elevation is formed from 3D digital map data at 1:10,000 scales. Average elevation is from 0.5 to 1.5m, this will be updated.

(ii) The control elevations of the road profile are calculated based on the calculated height of water level with frequency H1% or observed water levels, the locations crossing existing roads, rivers with required navigation clearances and the height of the crossing structures. In order to minimize construction cost, for the crossing locations between expressway and the existing roads (provincial roads, national highways or major arterial roads), we have considered to apply the design with flyover arranged on the crossing roads (for the crossing locations with sparse population along both sides of the alignment) and construction of frontage roads at the locations crossing residential areas or reinstatement of existing roads. For the sections in soft soil area, the design of viaduct is considered to ensure long-term stability of the road.

(iii) The finished grade is defined from the calculated water level H1% plus the required safety height of 0.5m (and if required, plus the height of waves), and plus the difference from road shoulder of the completion phase to outer edge of median. In addition, the outer edge of bottom of the pavement structure must be maintained above the permanent flooding water level at least 30 cm.

The finished grade is defined based on height of structures. For flyover bridges crossing existing roads, the finished grade is defined by required clearance of crossing roads plus height of structure. For bridges crossing rivers or channels, the finished grade is defined by navigation clearance plus height of structure (clearance of crossing roads and navigation clearances shall be agreed by local authorities or authorized management units). The finished grade must enable the arrangement of underpass and horizontal drainage system.

In Long An province and Ho Chi Minh City, the average existing ground elevation is about 1 m, and having soft soil area with thickness from 5 m to 25 m. Therefore, the average embankment height will be from 1.5 m to 2.5 m, at the area of soft soil with thickness less than 20 m a viaduct option will be considered. In Dong Nai Province, the alignment goes along Nhon Trach City with an existing ground elevation of 1 m to 2.5 m, and soil profile is rather better for embankment construction. The average embankment height is from 1m to 2m.

Due to having flat terrain, longitudinal grade of embankment is from 0% to 0.5%. Particularly, at the locations of Binh Khanh and Phuoc Khanh bridges which are large bridges with the required vertical clearance of 55m and in order to reduce construction cost, the maximum longitudinal grade is designed at 4%.

5. Typical Cross Section

130. Based on the results of traffic demand forecast, the number of lanes of the expressway will be 4 in phase 1 and expanded to 8 lanes in phase 2, which is in accordance with the Decision No. 1734/QD-TTg dated 01/12/2008 by the Prime Minister on the Road Network

41

Development Plan up to 2020 and the Orientation After 2020. Phase 2 is scheduled at the time of saturation traffic of 4 lanes road, which will be after 10-11 years from the opening year of Phase 1. 131. It was decided at the Interim Meetings that the ROW should be the minimum possible. This would mean only 7-metres beyond the construction limits of the Phase 2 of the expressway. In most places that meant a ROW of 73-metres in the embankment sections and 56-metres in the bridge and viaduct sections. 132. The options of selected alternative for cross section are as follows:

Phase 1 (4 lanes) Cross-section of 4 lanes option is shown in Figure III.5.

6. Pavement Design

133. There are two types of pavement that could be used on the project:

(i) Flexible pavement with asphalt concrete wearing surface for the main highway, and rigid concrete pavement for areas adjoining toll stations, and for interchanges and on/off ramps. The pavement structure will be selected based on the availability of construction materials. The availability of rock and other materials suitable for the pavement will be studied for the Ho Chi Minh City area. Axle load surveys on NH 51 and on NH1A have shown excessive overloading which must be curtailed on the Project Expressway if an economic pavement structure can be maintained in serviceable condition. Weight scales have been proposed at the toll plazas and entry to the road to prevent overloaded trucks from using the road.

(ii) Cement concrete pavement: the feasibility of using cement concrete pavement for the whole length of the expressway will be studied but Vietnamese experience has shown that it is more difficult to achieve the required quality with rigid pavement than using the common flexible pavement.

7. Soft Soil Treatment

134. More than half of the Ben Luc – Long Thanh expressway will be constructed on soft to very soft clay. These soft soils have a low bearing capacity and exhibit large settlements or failure when subjected to loading. It is therefore necessary to treat soft soil deposits prior to placement of the final road surface layer in order to prevent large settlement, differential settlements and subsequently potential damages to structures. 135. Different ground improvement techniques are available today. Every technique should lead to an increase of soil shear strength, a reduction of soil compressibility and a reduction in the time for construction. 136. The choice of ground improvement technique depends on geological formation of the soil, soil characteristics, cost, availability of backfill material and experience in the past.

43

137. Summary of soft soil treatment method is presented in Table III.11.

3. General Design at Interchanges

a. Interchange #1 with the HCMC-Trung Luong Expressway (IC1)

141. IC1 is located at section Km 00+700. Interchange calculation data:

(i) On the Ben Luc – Long Thanh Expressway : speed = 120km/h (ii) On the HCMC – Trung Luong Expressway: speed =120km/h (iii) Interchange ramp (direct): speed=50km/h (iv) Interchange loops: speed=40km/h

142. During the design process, many solutions were compared, due to the location of the interchange which has several control points: the transmissions lines Cao Dai Church in My Yen commune, My Nhan bridge, local road etc. Basic advantages and disadvantages of two alternatives are shown in Table III.13 and alternative 2 is recommended.

b. Interchange 2:

143. National Highway 1A Interchange is in Ho Chi Minh City, and links the expressway at Km3+420 to National Highway 1A. Interchange calculation data:

(i) On the Ben Luc – Long Thanh Expressway : speed = 120km/h (ii) On the National Highway NH1A: speed =80km/h (iii) Interchange ramp : - direct: speed=50km/h (iv) Interchange loops: speed = 40km/h

144. As system traffic of this region is very complex, the HCMC– Trung Luong Expressway after completion some of the traffic volume on NH1A will be attracted to HCMC – Trung Luong Expressway. This should reduce some of the congestion but the local area contains many industries such as the My An and Hiep Luong industrial estates which are currently expanding. There is also the Phu Trieu shoe factory and residential area located nearby. 145. Basic advantages and disadvantages of two alternatives are shown in Table III.14 and alternative 2 is recommended.

2. Large Span Bridges

166. BL - LT expressway must to cross two big rivers which are the Soai Rap and Long Tau rivers. These rivers are important waterways for linking ports at HCMC to others in Vietnam and overseas. In order to pass two big rivers, large span bridges were proposed and selected. 167. Clearances for large span bridges of project are presented in Table III.23.

b. Geotechnical Data at Large Bridges Area

169. There were three existing drilled wells that can be used for the bridge planning. The geotechnical condition is assumed by data from those drilled wells. The geological feature of object area is divided into 2 zones with layer (1) to layer (2). The cross section of for each drilled wells to be used to design are as shown in Figure 9 and 10.

c. Navigation Clearance

170. The vertical clearance of 55-metres and a horizontal clearance of 250-metres is required by the Vietnam Maritime Administration for the Soai Rap and Long Tau rivers for navigation clearance. This requirement will affect the overall cost of these bridges and so must be carefully studied. The dimensions of the ships estimated by the proposed navigation clearance are as follows:

(i) Vertical clearance of 55-metres is for a container ship of 40,000 DWT (ii) Horizontal clearance of 300-metres indicates a length of ship of 200-metres

171. It should be noted that the vertical clearance of 55-metres is the largest for any bridge currently in Vietnam. Navigation clearances of bridges in Vietnam are presented in Table III.24.

Figure III.10: Borehole at the Proposed Phuoc Khanh Bridge

d. Effect of High Voltage ( HV) Power Transmission Lines

172. The influence of the HV transmission lines on the proposed bridges cannot be ignored. The original Pre-FS alignment at the Binh Khanh crossing was designed to go between the 500-Kv and 200kV power-lines. This could prove rather dangerous from many aspects. First during construction there could be problems of cranes operating so close to these lines especially floating cranes. Later in the operation phase there are dangers of the collapse of the high electrical towers by reason of corrosion or wind gusts, the multiplier effect causing possible collapse of the bridge structure.

G. Traffic Forecast of Ben Luc – Long Thanh Expressway

1. Transport Facilities Development Plan and Major Development

176. The area along the BL-LT expressway is the one in Vietnam having highest growth in road traffic, waterway and airway. Now and in the future some of the largest ports will be operated. Long Thanh International Airport has been planned as the largest airport in Vietnam. Beside, in these districts, there are more than 20 industrial parks and major tourist areas. So the increase of traffic flow (ships, cars, aircraft, and passengers) will be very rapid in the period 2010-2030. Demands forecast of transport in the area studied by JICA, ADB and Vietnam is given in the Table III.27 to III.31.

Note: All construction materials for project (sand, soil, stone, cement, steel…) will be supplied and transported to the construction site by the material suppliers. Project will not implement any material exploitation activities for soil, sand, stone…. So, in principle, assessments of environmental impacts caused by material exploitation activities are not included in this EIA report. During construction of the expressway, locations of quarry and borrow sites, access roads, spoils disposal sites for wastes and other facilities will be determined by contractors. In this FS phase of the project specific locations of these facilities are yet to be determined, potential impacts of operation of these facilities and mitigation

67

measures may be only initially assessed (in Chapter V). Mitigation measures and monitoring in environmental management for these activities are initially proposed in Chapters V and IX.

2. Construction Machine and Equipment

183. In the feasibility study phase, the project has not proposed an exact figure for construction equipment. The contractor will propose a specific list of construction equipment when bidding and implementing construction. 184. However, based on an experience from the similar scale projects as HCMC – Trung Luong Expressway, Long Thanh - Dau Giay expressway, a number of construction equipment can be estimated as presented in Table III.36.

Table III.36: List of Construction Equipments for BL-LT Expressway

No. Items Capacity Quantity 1 Heavy truck > 20Tons 50 2 Trucks 10 – 20 Tons 100 3 Excavators 30 4 Bulldozer 20 5 Rammer 30 6 Air compressor 10 7 Pilling machine (pile drivers) 5 8 Leveling machine 20 9 Generator 10 10 Barges for bridge construction 10 11 Concrete mixing station 10 12 Asphalt mixing station 10 13 Other (various items) - J. Construction Process

1. Preparation Works

185. Preparation works include the following activities.

(i) Site preparation: construction area, after removing UXO (bomb, mine and other explosive materials), relocating power line, water supply pipe, fibre optic cable, the site will be handed over to contractor.

(ii) Site clearance: Removing existing building, structure and trees in construction site.

(iii) Manpower, equipment preparation: mobilizing manpower, mustering construction equipment, getting construction licenses. Total number of workers will be mobilized at the peak period is about 1, 000 persons working at the same time throughout the length of the road.

(iv) Set up auxiliary works: material transfer sites, temporary road, temporary drain, assignment road, site leveling. Construct camp, site office. Connect power line, install water supply system for domestic and construction, set up concrete mixing station and asphalt station.

68

2. Construction Works

186. Construction works include the activities below.

(i) Soft soil treatment and road sub-base works: to be conducted immediately after completing the road base construction, include: a) Execute the absorbent wicks; b) Banking, install pressure response temporary platform, loading, unloading and uninstall pressure response platform; c) Injection piles and concrete reduce-load platform after completing the road base loading activities.

(ii) Building bridges and viaducts: It will be carried out in parallel with the soft soil treatment and road base construction, included: a) producing girder and precast concrete structures; b) execution drilling piles; c) execute bridge abutment and piles on land and water; d) linking spans; e) execute horizontal beam, bridge flat, median area, bridge banister; f) execution pavement layer, installation elastic slot.

(iii) Execute road pavement, slope protection: 3 months after the end of the soft soil treatment works.

(iv) Install lighting system and security/safety signal system for land and waterway transportation

3. Completion Works

187. Completion works include the following activities. After completing the above construction works, the road should be carried out the completed works for going to operate. Complete work will be implemented at the end of construction time. The work includes:

(i) Repair of small defects (ii) Clean up the construction site, warehouses (iii) Collecting waste and superfluous materials (iv) Construction waste will be transported to licensed disposal site. (v) Return of the status of drainage system affected temporarily during construction

phase (vi) Cleaning the whole structure (vii) Repair to return of status of local roads effected during construction phase.

4. Principles of Construction Site Organization

188. The main principles of construction site organization are as follows.

(i) Construction sites should be located at high terrain area having advantage of geological condition.

(ii) Location of construction sites should be selected in order to minimize the potential impacts on local people.

(iii) Time accounting used must be consistent with the time limit for construction. (iv) Construction camps should be located out of the safety corridor of the high

voltage power lines. (v) Organization of 1-2 construction sites for each package for materials storage,

concrete mixing station, asphalt station and components manufacturing area, etc. (vi) A number of small construction sites along the alignment can be built to store

materials to create favorable conditions for construction activities.

69

(vii) In case the service road of construction site crosses the canal or ditch, depending on the actual situation, the specific application will be implemented as follows: a) in the case of dead-end canals, the leveling work will not affect people’s living conditions in the region as well as general drainage of the area. Filling canals or drainage ditches will be done only with agreement of local communities; b) Construction of temporary bridges and culverts with suitable load for transportation in case the flow must be maintained and can not be diverted around the construction camp.

K. Capital Investment of the Project

IV DESCRIPTION OF THE ENVIRONMENT

192. The present state of the environment at the project area, included 7 districts where the expressway will cross, is briefly described based on the results of field environmental and social surveys at all project communes and environmental analysis, implemented by the Environmental Protection Center (VESDEC) within the Vietnam Environment and Sustainable Development Institute (VESDI) for KEI in the ADB TA 7155-VIE.

(i) Soil map and land use map (1:50,000 and 1:100,000) (ii) Region 3: covering the left side of the Thi Vai river to the end of the expressway

at Long Thanh district, Dong Nai province. Its elevation gradually lowers with the average of 2-5m above the sea level. There are some small canals in this region.

(iii) Region 3: including the left side of the Thi Vai river to the end of the project site at Long Thanh district of Dong Nai province. Its 6 – 15 m surface layer of plastic clay or drift silt and needs treatment measures to secure stability and to stop subsidence. A common trend of this region is that the surface layer is weaker towards the end of the highway. The strong soil layer is at the depth of 30-40m.

193. The main thematic reports used in this EIA are:

(i) Report on the present terrestrial ecology at the project area (ii) Report on the present aquatic ecology at the project area (iii) Report on the present air, noise, vibration at the monitoring sites in the project

area. (iv) Report on the present surface water, groundwater quality at monitoring sites in

the project area. (v) Report on the present soil and sediment pollution (vi) Report on soil at the project district (vii) Report on the present socio-economy of 7 districts in the project area (viii) Reports on the results of public consultation and information disclosure on

environmental impacts based on synthesis of the questionnaires filled by 50 PAHs in the first round of public consultation, 547 PAHs in the second public consultation and comments on environmental issues of 15 Communes People Committees (PCs) and 15 FFCs.

194. The general information on the physical environment (climate, hydrology, topography, environmental quality), collected from various Governmental research units are also used in description of the environment at the project area. Some original data and information used for this Chapter are included in "Appendices to EIA Report". A. Physical Resources

1. Topography

195. The topography of the project area is separated into 2 distinctive regions:

(i) Region 1: covering districts of Long An province and Ho Chi Minh City. This region is flat, low (0-2.0 m above the sea level), and divided by numerous canals and rivers.

72

(ii) Region 2: covering Nhon Trach district of Dong Nai province. It is low knolls and hills - region, but much higher than that of region 1 (average height of 2-10m above the sea level).

2. Geology

196. The project site is geologically separated into 3 regions:

(i) Region 1: covering the districts of Long An province and Ho Chi Minh City. There is a weak 10 – 15 mud layer. Particularly, in Nha Be district, Can Gio district and a part of Western Nhon Trach district bordering the Long Tau river which has a weak 40m mud layer, it is not suitable for building road basements unless proper measures for treatment are taken to secure stability.

(ii) Region 2: covering Nhon Trach district of Dong Nai province. It is a low knolls and hills region with a good surface layer for building road basements of 20m thick and a strong layer at the depth of 25-35m.

(iii) Region 3: including the left side of the Thi Vai river to the end of the project site at Long Thanh district of Dong Nai province. Its 6 – 15 m surface layer of plastic clay or drift silt and needs treatment measures to secure stability and to stop subsidence. A common trend of this region is that the surface layer is weaker towards the end of the highway. The strong soil layer is at the depth of 30-40m.

3. Soils

a. Soil Classification

197. From the data provided by the Southern Agricultural Planning Institute of Ministry of Agriculture and Rural Development for VESDEC (June 2009), there are 7 main soil groups in 7 districts of the project area identified (Table IV.1). The soil map of 7 districts is given in Figure.IV.1. Out of 7 soil groups, 28 classes of soils have been determined.

209. To minimize the impacts caused by dredging and/or leveling activities at the acid sulphate soil area, during the design phase the project should carefully study soil physico-chemical properties at various places along the project ROW. From the results of this study the project will identify the appropriate measures for acidity control at each section.

d. Atmospheric Temperature

210. Air temperature directly affects the conversion and diffusion of air pollutants in atmosphere. The higher the air temperature, the quicker chemical reactions and the shorter the residue of pollutants. Variations of air temperature have strong influence on the diffusion of suspended particles (dust) as well as heat exchange in workers’ body and health.

(i) The highest monthly average of 26.6 0C was recorded at Tan An Meteo-Hydrological (MH) Station, 30.10C at Tan Son Hoa MH Station (Ho Chi Minh City) and 29.70C at Bien Hoa MH Station (Dong Nai province).

(ii) The lowest monthly average of 24 0C was recorded at Tan An MH Station, 25.50C at Tan Son Hoa MH Station and 25.40C at Bien Hoa MH Station.

The monthly averages of temperature over years at the three MH stations in the project area are shown in Table IV.4.

e. Sunlight Hours

211. Together with solar radiation, sunlight hours are one of the factors of direct effects on regional thermal regime and on atmospheric stability and the diffusion – transformation of air pollutants. The sunlight hours have direct effects on biochemical processes of flora and fauna and on human health. Table IV.5 provides data of sunlight hours measured at the three MH stations in the project area.

h. Winds

214. According to statistical data, the project area is affected by two dominant winds, the W-SW and the N-NE. The W-SW wind is dominant in the rainy season with the average speed of 3.6 m/s and the N-NE wind in the dry season with the average speed of 2.4 m/s. In addition, monsoon blows over the project area in the N-SE direction in the period from March to May with the average speed of 3.7m/s. In fact, according to monitoring data obtained from the 3 stations in the project site, the maximum wind speed is very high with the highest recorded by Tan An MH Station and followed by that of Bien Hoa MH Station. Tan Son Hoa MH Station of Ho Chi Minh City did not show the highest yet an abnormal speed of 15 m/s was recorded there on July 2007. The highest wind speeds measured by the stations are shown in Table IV.8.

4. Hydrological Regime

a. Network of Canals and Rivers in the Project Provinces

215. All rivers, canals and creeks, where the Expressway will be constructed, are located in the downstream region of the Dong Nai - Sai Gon and Vam Co basins. The Dong Nai - Sai Gon river basin makes up a major part of two provinces in the South of the Central Highland, namely Dak Nong and Lam Dong. It covers up almost all provinces in the Southern Economic Focal Zone (Tay Ninh, Binh Phuoc, Binh Duong, Dong Nai, Ba Ria – Vung Tau, Ho Chi Minh City and a large part of Long An. It also expands to a part of Tien Giang province in the Mekong Delta, parts of Binh Thuan and Ninh Thuan provinces in the South of Central Vietnam, and Dak Lak of the Central Highland. 216. Ben Luc- Long Thanh Expressway alignment will run across 20 rivers and canals names and width of which are indicated in Table IV.9.

b. Hydrological Characteristics

i. Hydrological Regime of the Dong Nai - Sai Gon River Systems

217. The flows in the basin of the Dong Nai - Sai Gon river system depend upon rainfall and the tidal regime from the East Sea. The hydrological regime is, therefore, spatially and time wise variable. Flows are strong when rain is heavy, weak when rain is light. The flows are ever stronger in strong tide (high tide), going further to land with high amplitude and weaker in low tidal period.

85

218. There are two main seasons in the basin (rainy and dry seasons) and therefore, there are two corresponding regimes: flows in the rainy season and flows in the drought season. The changes in flows of the two seasons are very contrasting. 219. The stream system in the site to be crossed over by the project highway is dense with a critical role to play in waterway and flood drainage. It, however, creates conditions for saline water to intrude further to inland. Flows of the largest rivers in the Dong Nai - Sai Gon Basin are shown in Table IV.10.

ii. Hydrological Regime of the Small River and Canals in the Project Area

220. Hydrological regimes of all small rivers (Can Giuoc, Ba Lao, Thay Cai, Cha, Ong Keo, Bun Ngu etc) and canals where the project alignment crosses fully depend on tidal regime and hydrological characteristics of the large rivers (Dong Nai, Sai Gon, Soai Rap, Nha Be, Long Tau etc). 221. Some main hydrographic data of river and canal system on the project route are as follows:

(i) The highest water level with frequency of 1% : +1.55m (ii) The highest water level with frequency of 5% : +1.50m (iii) The lowest water level with frequency of 99% : -2.0m (iv) Average tidal range in day : 1.5m (v) The highest speed : 2.0m/s (vi) The average speed : 1.2m/s

222. Excepted for the Soai Rap river, other rivers do not have this phenomenon. River beds and banks at both sides of the rivers are stable; they do not have erosion phenomenon and bank movement.

5. Surface Water Quality

223. In order to assess the water quality of the rivers and canals on the route of Ben Luc – Long Thanh Expressway, in the period from 20 to 25 May 2009 and from 17 to 24 August 2009, the EIA Study Team has conducted investigations and sampling at 10 sites in May and 13 sites in August in the project area. Locations of sampling sites are detailed in Table IV.11 and Figure IV.2. Results of water quality analyses are given in Tables IV.12 and IV.13.

Source: All the tables from Table IV.11 onwards are the data from research and study of the EIA Team of VESDEC for KEI in the Project of ADB TA 1755-VIE, 2009. 224. From the results obtained from analyses of surface water quality at the monitoring sites, the following evaluation on the present surface water quality is given. 225. Regarding pH values, in the early rainy season (in May 2009) at the monitoring sites on the rivers and canals in the project site, pH varied in the range of 6.32 – 8.05 with the highest (8.05) at the Thi Vai river (Phuoc An commune) and the lowest (6.32) at Nha Be river (Long Thoi commune). High pH indicates the effects of further saline intrusion to the Thi Vai river whilst low pH (lower than 6) reveals that watercourses are acidified (contaminated by acid sulphate) due to irrigation and construction in ASS regions. In the middle of the rainy season (in August 2009), pH at the monitoring sites (6.14 – 7.08) all decrease compared to that in May.2009 due to the effect of wash – out water through ASS areas. 226. Regarding Organic Pollution, in the early rainy season (In May 2009), dissolved oxygen (DO) contents at monitoring sites varied in the range of 2.1 – 5.4mg/L, of which the highest was recorded at the Long Tau river (at Phuoc Khanh commune) and the highest at the Thi Vai river, Ben Ngu canal (at Phuoc Thai commune). The results indicate that the Thi Vai river is heavily polluted by organic matters (DO: 2.1 – 2.5 mg/L). The canals such as Tan Tuc and Ba Lao in Can Giuoc district also have significant of organic pollution (DO: 3-4 mg/L).

87

227. Chemical oxygen demand (COD) varied in the range of 8 - 48mg/L whilst biochemical oxygen demand (BOD) at the monitoring sites was 4 - 34 mg/L. Results of COD and BOD analyses pointed out the worst organic pollution at the rise of the Thi Vai river (Phuoc An commune, Nhon Trach district – site CT9 and Phuoc Thai commune, Long Thanh district – site CT10), where BOD and COD were 25 - 34 and 38 - 48 mg/L, respectively, far higher than the allowable limits set forth in the National Technical Regulation of Surface Water Quality (QCVN 8:2008/BTNMT) for “Source Ib”. Organic pollution of the Thi Vai River is mostly due to industrial effluents from Vedan, Nhon Trach, and Go Dau industrial parks. 228. Organic pollution of the Nha Be and Long Tau rivers (sites CT4, CT5, CT6 and CT7) is slightly lower with BOD of 4 – 6mg/L. Apparent organic pollution was observed at Tan Tuc canal and the Can Giuoc river (BOD: 6 – 8 mg/L). That is mostly caused by sanitary wastewater from Ho Chi Minh City. 229. In the middle of the rainy season (in August 2009), the increase in flows, dilution and self – purification leading to organic pollution in most of rivers, canals and creeks are obvious decrease: in DO (3.0 - 6.3); decrease BOD (2 - 8 mg/L). The sites, which have obvious organic pollution, are Tan Tuc and Ong Keo canals; however they are still complied to the B-Water Source in the National Technical Regulation (QCVN 08: 200/BTNMT, column B). 230. Regarding saline intrusion In May 2009, electrical conductivity (EC) readings at the monitoring sites were in the range of 330 – 33,000 µS/cm. That means the Thi Vai river underwent the worst saline intrusion whilst Can Giuoc canal and Nha Be river were affected by salinity to a certain extent. 231. Salinity at the monitoring sites are of between 168 and 21,003 mg/L (in May) with the highest at Ben Ngu canal at Phuoc Thai commune (21,003 mg/L) due to strong saline intrusion from the estuary of the Thi Vai river. The lowest salinity is at Ong Keo canal (168 mg/L). The investigation was performed at the end of the dry season and the beginning of the rainy season yet there was no rain there before and after the time of survey in the project sites. 232. In May 2009, nutrient pollution at Nha Be, Long Tau rivers is low. However, nutrient pollution is certainly occurring as for the Tan Kien river, the Can Giuoc river and Ba Lao canal. Eutrophication can take place with such nitrogen and phosphorus concentrations, damaging the growth of aquatic animals and deteriorating water quality. The sources of nutrient pollution in the study sites include domestic wastes, animal waste and wastewater from food, tanning, paper industries and runoff from fields where chemical fertilizers are used. In the August 2009, the increase in dilution and self-cleaning capacity leads to the decrease in nutrient pollution at the rivers and canals significantly. 233. Regarding metal pollution, in May and August 2009, pollution of (Fe, Al) as a result of soil erosion and run-off water to rivers and canals in the project site is still low. The concentration of toxic heavy metals (Cr, Cd, Hg, and Pb) at all monitoring sites was far lower than the permissible limit in Column A1 of the National Regulation for Surface Water Quality (QCVN 8:2008/BTNMT). 234. Regarding oil pollution, in May 2009, contents of mineral oil in surface water at the monitoring sites were 0.08 to 0.72 mg/L. The highest value was found on the Nha Be River, at Long Thoi since that has high traffic of boats and barges. The lowest value was found on Ong Keo canal, at Phuoc Khanh commune. In August 2009, oil concentration obviously decreased.

88

235. Regarding microbiological pollution, coliforms contents in surface water at the monitoring sites varied in the range of 2.3x102 to 9.3x104 (MPN/100mL) in May 2009 and from 75 to 14.000 MPN/100mL in August 2009. These are from low to quite high value. The highest value was found on Ba Lao canal (NM5) and the lowest Ong Keo canal (NM8). According to the results, up to 9 rivers and canals showed levels of microbiological pollution higher than the permissible limit in the National Technical Regulation in surface water (QCVN 8:2008/BTNMT). However, in the middle of rainy season, the level of microbiological pollution obviously decreases. The main cause of microbiological pollution is wastes from residential areas and boats.

6. Sediment Contamination

236. Sediment samples were collected at the same locations as 13 surface water sampling sites as shown in Figure IV.2 and Table IV.11. Analyzing results of sediment contamination are given in Table IV.14, and IV.15.

237. From data in these tables the followings are found:

(i) Fe content in sediment at the monitoring sites varied in the range of 30.22 – 52.41 g/kg (in May 2009) and 43.01 - 76.46 g/kg (in August. 2009). which is also in equivalent to the average Fe content at many sites in Vietnam (VESDEC, 2006).

(ii) Zn content in sediment at the monitoring sites was in the range of 80.27 – 247.09 mg/kg and 79.15 - 155.17 mg/kg (August 2009) which is relatively high (20 – 50% higher than that of sediment in Tien Giang province (2006) and the Thi Vai river (1995. 2000)). The highest content of Zn was found at Ba Lao and Ong Keo canal.

(iii) Cr content in sediment samples was in the range of 29.27 – 56.72 mg/kg (May 2009) and 40.17 - 125.0 mg/kg (August 2009). That is not much different from the results obtained in the studies in Ho Chi Minh City and Tien Giang in the previous years. The monitoring sites of the Thi Vai river have the highest Cr content in sediment.

(iv) Hg content varied from 0.10 to 0.24 mg/kg (May 2009) and 0.08 – 1.43 mg/kg (August 2009). From the observed results the highest Hg content was found at Ba Lao canal, Long Tau river. Hg content was over 1.0 mg/kg is much higher than other sites in Vietnam. However, it is much lower than the allowable limit of the Dutch Standard for Sediment.

(v) Cd content in sediment samples was of between 0.023 – 0.10 mg/kg (May 2009) and 0.003 - 0.031 mg/kg (August 2009) which are lower than that in Ho Chi Minh City, Quang Nam and Quang Ninh provinces (VESDEC. 2000 – 2006). The highest Cd content was found at Tan Tuc canal and the lowest at Nha Be river at Hiep Phuoc commune.

(vi) As content varied in the range of 2.54 – 11.42mg/kg 2.4 – 11.42 mg/Kg (May 2009) and 3.38 - 7.04 mg/kg (August 2009). The As content in sediment of rivers and canals in the study area was far higher than that at Quang Ninh, Quang Nam provinces, but did not exceed the Permissible Standards of various countries (USA, Canada, Hong Kong, Netherlands etc.) The analytical result of sediment taken at CT5 (Nha Be River. Long Thoi area) showed the highest As content.

(vii) Mineral oil content in sediment at the monitoring sites varied in the range of 21.80 – 26.40mg/kg (May 2009) and 1.2 - 6.8 mg/kg (August 2009). Such analyzing results indicate significant oil pollution in sediment at the canals and rivers in the study area. That is a consequence of river pollution due to waterway transport and industrial effluents.

238. By comparison the residues of heavy metals in bottom mud of the rivers and canals in the study area and the Dutch, US EPA and Canadian Standards of Sediment Quality (at present, Vietnam has no standard of sediment quality), it is found that sediment at the rivers and canals in the study area is contaminated by heavy metals, which is, however, far lower than the allowable limits of those standards.

7. Soil Contamination

239. In order to assess the soil quality of the project site in May and August 2009, the project's EIA Team carried out the sampling and analyses of soil samples taken at 12 sites (Figure IV.3 and Table IV.17), results of analysis are given in Table IV.18 and IV.19.

240. From analyzing the results above some remarks may be given.

(i) Compared to the National Technical Regulation of Heavy Metal Contents in Soil for Agriculture (QCVN 03-2008/BTNMT) and the US EPA and Dutch Standards of Sediment, the existing contents of As, Cd, Zn, Cr, Hg in soil at the study area are far lower than the allowable limits.

(ii) The residues of heavy metals in sediment of the study sites are usually higher than that of soil. This is explained by the fact that heavy metals are washed out from soil and accumulated in bottom mud. This is a common phenomenon in many basins in Vietnam.

8. Groundwater Quality

241. Samples of groundwater (water in drilled wells) collected at 12 sites in May and August 2009 in the communes along the project alignment were analyzed. The monitoring sites relating to the ground water quality are given in Figure IV.3 and Table IV.20. Results of laboratory analysis are shown in Tables IV.21 and IV.22. 242. The investigation of the existing quality of groundwater is aimed to evaluate the possibility of using water for local people and construction workers in the future when the highway is under construction.

243. The conclusion from the analysis is that: at present groundwater in the study area is not polluted by As, ammonium, nitrate, nitrite and microorganism. Nevertheless the concentration of iron and oil at some wells are higher than the permissible limits.

9. Air Quality

244. In order to obtain baseline data of air quality in the project site, in May 2009 and August 2008, the EIA Team of the project has carried out ambient air sampling and analysis at 12 sites (in May 2009) and 15 sites (in August 2008). Locations of air quality monitoring sites are shown in Figure IV.5 and Table IV.23. Analysis results of air quality are given in Table IV.24 and IV.25.

Notes: VT1 – VT12: locations of air, noise and vibration monitoring sites in the first survey (May 2009) VT1 – VT15: locations of air, noise and vibration monitoring sites in the second survey (August 2009) 245. Considering the results of air quality analyses shown in Table 63 and 64, there are some remarks below may be given. 246. Total suspended particles (TSP) at all sites in May 2009 varied in the range of 0.19 - 0.81 mg/m3. Excepting at VT4, VT5, VT7, VT8 and VT12, the TSP content were higher than the allowable limit set forth in the National Technical Regulation for Ambient Air Quality QCVN

102

05:2009 (maximum TSP in ambient air: 0.30 mg/m3). The highest TSP value was at VT2 (0.81mg/m3) and the lowest at VT12 (0.19mg/m3). The TSP content is higher than the allowable limit in the QCVN 05:2008, mostly caused by heavy traffic (particularly at VT2: on National Road 1A at Binh Chanh district, VT6: on Nguyen Van Tao street in Nha Be district, VT10: and on National Road 51 to Vung Tau). 247. In August 2009, TSP contents in almost places were still high (0.26 – 1.28 mg/m3), because of the sampling time in sunny days. At present, at some sites on the traffic roads (VT2, VT3, VT10, VT12) levels exceed the allowable limit many times. PM10 contents at most of the monitoring sites in 2 monitoring occasions were higher than the Vietnamese standards and IFC/WB (WHO’s Standard) which is 0,15 mg/m3 (24 hrs – averaging period).

(i) NO2 concentration at monitoring sites in May 2009 was 0.03 to 0.44mg/m3. Excepted for VT2, VT6 and VT10, the NO2 concentration at other monitoring sites were lower than the allowable limit set forth in TCVN 5937 – 2005 (maximum NO2 concentration in ambient air is 0.20mg/m3). The highest NO2

concentration was measured at VT2 (0.442mg/m3), which is a point of heavy traffic on National Road 1A crossing Ben Luc district. In August 2009, NO2

concentration at the all sites varied from 0.002 – 0.346 mg/m3, the highest value at National Roads No.1A and No. 51 (VT10)

(ii) SO2 concentration at monitoring sites in May 2009 varied in the range of 0.012 – 0.319mg/m3, which are lower than the allowable limit of the TCVN 5937 – 2005 (maximum SO2 concentration in ambient air: 0.35mg/m3). The highest concentration was found at VT2 (0.319 mg/m3) and the lowest at VT12 (0.012mg/m3). In August 2009, SO2 concentration at all sites varied from 0.02 to 0.31 mg/m3. The highest value which slightly exceeds the allowable limit is at National Road No.51 (VT10).

(iii) CO concentration at monitoring sites in May 2009 and in August 2009 was of between 2.48 and 10.27mg/m3, which are lower than the allowable limit of the TCVN 5937 – 2005 (allowable CO concentration: 30mg/m3). The CO concentration was highest at VT2 (10.27mg/m3) and lowest at VT12 (0.01mg/m3).

(iv) PM10 content at monitoring sites in May 2009 varied in the range of 0.17 – 0.72mg/m3 with the highest at VT2 (0.72 mg/m3) and the lowest at VT12 (0.17mg/m3). PM10 dust usually accounts for a high percentage (more than 80%) in the TSP. At some monitoring sites, the PM10 values were far higher than the allowable limit of the TCVN 5937 – 2005. In August 2009, PM10 content varied from 0.12 to 1.25 mg/ m3, some sites with high PM10 concentration are National Road No.1 (0.45 mg/m3). National Road No.51 (1.15 mg/m3).

(v) Volatile organic compounds (VOC) concentrations at monitoring sites were of between 40.0 and 77.8mg/m3 with the highest at VT1 (77.8 mg/m3) and the lowest at VT9 (40.0 mg/m3) in May 2009 and 1.34 - 47.54 mg/m3 in August 2009, the highest at VT1, VT2, VT3, VT10.

(vi) Lead concentration at monitoring sites in May 2009 and in August 2009 varied from 0 to 0.009 mg/m3 with the highest at VT12 (0.089 mg/m2) and the lowest at VT8 and VT11 (no detectable: <0.001 mg/m3)

LA90: is the noise levels that are 90% exceeded for a sample period. At these levels, the baseline noise level (initial sound) is minor. LA10: is the noise levels that are 10% exceeded for a sample period, usually 60 minutes. LAmax: is the maximum sound from a single source. LAmin: is the minimum sound from a single source. 249. From the data in Tables IV.26 and IV.27 the following evaluation of present noise pollution at the monitoring sites may be given.

250. Daytime noise at monitoring sites in May 2009, in the duration from 06:00 to 18:00 varied from 43.9 to 92.1dBA. Excepting data site VT2 (National Road 1A at Ben Luc district), VT4, VT6 (National Road 15 at Nha Be district) and VT10 (National Road 51 at Long Thanh district), noise at monitoring sites was lower than the allowable limit set forth in TCVN 5949 – 1998 for residential areas amid areas of trading, manufacturing and services from 06:00 to 18:00 is 75.0dBA, but higher than that for residential areas, hotels and offices. The similar situation was recorded in August 2009. In comparison with the IFC/ WHO (WHO’s for noise at daytime: 70 dBA for commercial and industrial areas and 55 dBA for residential areas) noise level at various places exceed the permissible limits. 251. Evening time noise at monitoring sites from 18:00 to 22:00 was in the range of 51.7 – 90.6 dBA (in May 2009). Some monitoring site noise levels were higher than the allowable limit set forth in TCVN 5949 – 1998 (maximum noise in residential areas amid areas of trade, manufacture and services from 18:00 – 22:00: 70dBA). The highest noise level was measured at VT2 (90.6 dBA), and the lowest at VT9 (51.7 dBA). 252. Night-time noise levels at the monitoring sites from 22:00 to 06:00 were in the range of 48.8 – 88.6dBA. Except for site VT9, noise at almost of the monitoring sites was higher than the allowable limit set forth in TCVN 5949 – 1998 (the maximum noise in residential areas amid areas of trade, manufacture and services from 22:00 – 06:00 is 50dBA). The highest noise pollution was at site VT2 (88.6dBA) and the lowest at VT9 (48.8dBA).

11. Vibration

253. The vibration was monitored in May and August 2009 at the same sites of air quality and noise monitoring where the alignment crosses. The results of vibration measurement are shown in Tables IV.28.

B. Ecological Resources

1. Aquatic Ecosystems

a. Location of Sampling Sites

255. To obtain baseline data on the present aquatic ecosystems at the project area, in May and August 2009, the EIA Team has conducted two field surveys for sampling aquatic organisms at the main rivers and canals where the Ben Luc - Long Thanh Expressway will cross. Locations of aquatic organism sampling sites are the same as locations of surface water sampling sites (Table IV.11, Figure IV.2). Analytical results on phytoplankton, zooplankton, benthic animals and fish eggs are shown in Appendices IV.2.1 – IV.2.8 (Volume "Appendices to EIA Report")

b. Phytoplankton Communities

i. Species Composition

256. In May 2009 there were 134 species belonging to 7 classes of phytoplankton recorded at the monitoring sites. The species composition structure is shown in Table IV.29.

Table IV.29: Species Composition of Phytoplankton in the Project Area

May 2009 August 2009 Classes

No. species Percentage (%) No. species Percentage (%) Cyanophyceae 18 13.4 11 11.2 Bacillariophyceae 58 43.3 45 45.9 Chlorophyceae 18 13.4 16 16.3 Zygnematophyceae 25 18.7 13 13.3 Euglenophyceae 9 6.7 6 6.1 Xanthophyceae 1 0.8 - Dinophyta 5 3.8 7 7.2 Total species 134 100 98 100 257. In August 2009, the number of phytoplankton was fewer in 36 species than that in May 2009. Species numbers of Cyanophyceae, Bacillariophyceae, Chlorophyceae Zygnematophyceae, Euglenophyceae, were reduced by 7 species, 13 species, 2 species, 12 species and 3 species, respectively. Only species number of Dinophyta was increased byn 2 species. 258. Species composition (percentage-%) only changes in Chlorophyceae and Zygnematophyceae. The increase of freshwater discharge from the upper river Dong Nai pouring into Ong Keo causing decrease in typical species of acid water (Zygnematophyceae) may be a reason for this change. 259. There was not a great fluctuation in the species number of Coscinodiscus, Chaetoceros and Nitzschia (Bacillariophyceae) species between two seasons and their distribution at all sampling sites. It means that basic characteristics of rivers and canals of the project area are salty or originally salty and rich in nutrients. 260. The species characterized for the acid sulfate water included Phormidium chalybea, Eunotia lunaris, Actinastrum hantzschii, Ankistrodesmus fusiformis, Coelastrum cambricum, C. microporum, Anthrodesmus constrictus, A. curratus, Closterium acerosum, C. gracile, Cosmarium contractum, Staurastrum (13 species in total). They appeared commonly in Tan Tuc and Ong Keo canals.

115

ii. Phytoplankton Abundance and Most Dominant Species

261. Quantity of phytoplankton in the project area fluctuated from 4,460 (site CT7) to 651.320 cells x liter-1 (site CT9). The dominant species were Cyclotella sp.. Melosira granulata, Skeletonema costatum that are indicators for organic polluted environment. The highest at the Thi Vai river (CT9) and the lowest at the Long Tau river (CT7). At the remaining sites, the dominant species were Cyclotella meneghiniana, Coscinodiscus lineatus, Skeletonema costatum and Peridinium sp.

iii. Biological Indices

262. The biodiversity Index (H') of phytoplanktons at rivers and canals of the project area varied from 0.36 to 3.05 (Table IV.30). The highest value was at CT7 and the lowest one at CT9.

263. The biodiversity Index (H') of phytoplanktons at rivers and canals in May 2009 varied from 0.15 to 0.93, the highest value at CT10 and the lowest one at CT8. In August 2009, it varied form 0.18 to 0.85, the highest value at CT4 and the lowest one at CT7.

c. Zooplankton Communities

i. Species Composition

264. Analytical results in August 2009 recorded 28 species with 3 forms of larvae while 28 species with 4 forms of larvae recorded in May 2009. Species composition structure is shown in the Table IV.31.

In general, there was no great fluctuation in species composition of zooplankton in the project area. The situation is the same for freshwater species and saline water. In May 2009, freshwater and brackish water species included Rotatoria, Cladocera distributed at Tan Tuc

116

canal (site 1), Can Giuoc and Ba Lao canals and a few in Nha Be river (sites CT4-CT6) and Ong Keo canal (Site CT8). In August 2009 these species were distributed mainly at canals of Tan Tuc and Ong Keo due to large discharges of freshwater from the upper of the Dong Nai river pours into Ong Keo canal. There was not much change in freshwater species at canals of Can Gio, Ba Lao and Nha Be river. 266. At Tac Son Tra and two small canals in Binh Khanh commune, included species of brackish water crustaceans. Particularly, in site CT12 Asplanchna sieboldi,. Diaphanosoma excisum and Moina dubia appeared due to direct effects from water source of the Nha Be river with low salinity. The species indicated for the rich nutrient water and organic pollution were Philodina roseola, Rotaria rotaria, R. neptunia, Brachionus calyflorus, B. plicatilis, Sinantheria socialis, Moina dubia, Mesocyclops leuckarti, Thermocyclops hyalinus at canal of Tan Tuc, rivers of Can Giuoc, Ba Lao and Ong Keo. Howerver, the level of pollution at Tan Tuc canal is slighter. Saline water species of Oithona similis, Acartia clausi, distributed in the rivers of Long Tau, Thi Vai and Ben Ngu.

ii. Zooplankton Abundance and Most Dominant Species

267. Quantity of zooplankton in the project area greatly fluctuated from 2.700 – 16.000 individuals x m3 , the highest value at CT10 and the lowest at CT11 and CT12. The dominant species were Asplanchna sieboldi and Brachionus falcatus at Ong Keo canal, Acartia clausi, Oithona similis and Nauplius copepod at other sites.

iii. Biological Indices

268. The biodiversity Index (H') of zooplankton shows characteristics of environmental quality of the study area. H' varied from 0.33 to 1.94 (May 2009) and from 0.56 to 2.15 (August 2009) (Table IV.32), the highest value at CT1, CT2 and the lowest one at CT7.CT8 (in Nhon Trach district).

269. The dominant index values of phytoplankton show the stable level and development trend of the study area and varied from 0.27 to 0.94. The highest value was at CT8 and the lowest at CT2.

d. Benthic Macroinvertebrates

i. Species composition

270. From the results of species examination of benthic macroinvertebrates at 10 sites (in May 2009) and 13 sites (in August 2009) at canals and rivers of the proposed Ben Luc – Long Thanh Expressway area, there were 13 species identified (May 2009) and 18 species (August 2009). The species composition structure is shown in the Table IV.33.

117

271. Analyzing the species composition structure of benthic macroinvertebrates at rivers and canals at the project area can be seen that, sea originated organism accounts for higher rates in August 2009 than that in the early of the rainy season (May 2009). 272. The freshwater species were Limnodrilus hoffmeisteri at Can Gio canal - Ong Keo bridge; Melanoides tuberculatus at Tan Tuc canal, rivers of Can Giuoc and Ba Lao and Pila polita at Tan Tuc canal. Sea original species distributed at almost sampling sites, except for Tan Tuc canal. 273. Melanoides tuberculatus indicates for the medium rich nutrient and organic pollution water at not only Tan Tuc canal (CT1) but also Ba Lao canal (site CT3). Limnodrilus hoffmeisteri and Melanoides tuberculatus indicates for the medium to high rich nutrient and organic pollution water at Can Gio (CT2). Owenia fusiformis, Capitella capitata, Bispira polymorpha indicates polluted water at Nha Be river (CT5 andCT6), Ong Keo (CT8) and Thi Vai river (CT9 and CT10). 274. The distribution of Grandidierella lignorum, Tachaea sp., Cyathura truncata, Alpheus bisincisus at rivers of Nha Be, Long Tau (CT17), Tac Son Tra (CT11), two small canals of Binh Khanh commune (CT12 and CT 13) shows the environment less polluted than other rivers and canals which the project alignment goes across. They are medium polluted (β-mesosaprobic). 275. The presence of Solen sp (Bivalvia), Nephthys polybranchia, Owenia fusiformis, Capitella capitata, Bispira polymorpha, Amphioplus laevis, Melita sp., Grandidierella lignorum and young crabs identified that water at the Thi Vai river, Ben Ngu canal in Long Thanh area was polluted at medium level.

ii. Structure and Quantity

276. Quantity of benthic macroinvertebrates in the project area highly fluctuated from 60 to 21.250 individual/x m2. The highest density was at CT4 and the lowest at CT5 and CT6. The dominant species were Pila polita at Tan Tuc canal, Melanoides tuberculatus at Can Giuoc canal, Nephthys polybranchiai at Ba Lao canal and in Nha Be river, canals of Ong Keo and Ben Ngu. Owenia fusiformis in the Nha Be river (Nha Be Petrol Storage Area) and Hiep Phuoc port, Tachaea sp. In the Long Tau river, Grandidierella lignorum and Tachaea sp occurred at rivers and canals in Binh Khanh commune.

iii. Indices Analysis

277. Based on Biological Indices H’ (Shannon. 1948), analytical results of H’ of benthic macroinvertebrates at rivers and canals of the project Ben Luc- Long Thanh area fluctuated from 0.02 to 1.42 (May2009) and 0.41 – 1.53 (August 2009) (Table IV.34).

Indices H’ of benthic macroinvertebrate at the project area is low due to strong effects from industrial and domestic wastewaters in the upper area.

iv. Dominant Indices (Berger - Parker. 1970)

279. Indices D of benthic macroinvertebrates at the project area fluctuated from 0.54 to 1.0 (May 2009) and 0.39- 0.87 (August 2009) (Table IV.35).

Fish Eggs – Juveniles 280. In May 2009, at 10 sites only one juvenile of Gobiidae was recorded in the Nha Be river at Phu Xuan (CT4). There were not any larva forms of Zoe and Mysis in the other sites. In August 2009, fish eggs were recognized in 3/13 sites. Fishery Resources 281. Can Giuoc river and Ba Lao canal are the wastewater drainage channels in the Southwest of Ho Chi Minh City. These rivers have black water and mud with smell, high suspended solids, high turbidity (the transparency measured by Secchi: only from 10 to 15 cm in the low tide period and; from 20 to 25 cm. in the high tide). There are no fishing activities at these rivers. Fishing activity in canals of Tan Tuc and Ong Keo and rivers of Ben Ngu and Thi Vai (heavily polluted) were also not observed. 282. The Nha Be river from Phu Xuan to Hiep Phuoc and the Long Tau river at Phuoc Khanh commune receives wastewater from upstream region. With high self-purification, water quality of this river in this area was better than that in other sites at the upstream region. However, there were not any fishery activities, recorded in this river section. The reason may be this is a route for large ships coming in and out, so the fishery activities were limited. There was only a section of the Nha Be river about 5 km far from upstream of Phu Xuan and 3km downstream of the Soai Rap river where fishery activity was observed. The fishing tools were sunken traps ("ghe đáy" in Vietnamese) and fishing nets. The number of sunken traps fluctuated from 8 to 10 traps in each section. In addition, there were two sunken trap lines (from 3 to 5 sunken traps in each line) at the Long Tau river at Tam Thon Hiep commune area. 283. Fishery activities: sunken traps were used in two periods of 1st and 15th lunar calendar (from 6 to 7 days of each strong tide or weak tide). In low tide, sunken traps were used in 4 or 5 hours, in this duration each trap may collect 0.5 to 1 kg of shrimp and 3 to 4 kg of fish.

119

284. The shrimp species such as Metapenaeus ensis, Metapenaeus lysianasia, Macrobrachium mirabile, collected in this area have small sizes and low quality. Macrobrachium mirabile seems to be the most dominant species. 285. The fish species commonly recorded in this area are Pristolepis fasciata, Polynemus sp., Zenarchopterus clarus, Bagroides sp., Stolephonus, Coilia grayii, Septipinna taty, Arius truncatus. The high quality species are Penaeus merguiensis, P. indicus, Macrobrachium rosenbergii (shrimps), Pissodonophis boro, Macrotrema caligano, Lates calcarifer, Plotosus canius, and Pangasius polyuradon (fish). 286.

e. General Evaluation on the Present Aquatic Ecology

287. Based on species composition, density, bio-indicators, dominant species, indices, the characteristics of aquatic ecosystems of the canals and rivers in the Ben Luc – Long Thanh Expressway project area may be identified as follows.

(i) Low brackish water (S ≤ 5‰) are found at the rivers and canals of Can Giuoc, Nha Be, Tan Tuc, Ba Lao, Ong Keo; typical brackish water (S: 5 - 20‰) are the rivers of Long Tau, Thi Vai and Ben Ngu.

(ii) The acid sulfate water includes the canals of Tan Tuc (CT1) and Ong Keo (CT8). (iii) Water in the project area is polluted from industrial and domestic wastewaters in

the levels of mesosaprobic to polysaprobic. (iv) There was only one juvenile that was recorded in the Nha Be river at Phu Xuan

area, while there was any larva forms of Zoe and Mysis in all sites.

122

(v) There were many high economic aquatic species at rivers and canals of Dong Nai- Sai Gon water basin. Due to pollution and over exploitation, the fish resource has decreased. At present, fishery source at canals and rivers where the expressway runs across is low. Therefore, pollution control during project construction activities to protect aquatic organisms in canals and rivers are necessary.

(vi) The obtained information and data from various studies indicate that at the rivers and canals where there the expressway will traverse there are not species of aquatic organisms belonging to the rare species listed in the Vietnam’ Red Book (2000).

(vii) Depending on seasons location of fish breeding grounds are changed, but they are concentrated mainly at the mouths of the Soai Rap and Long Tau rivers, far from the project alignment. There is not an important breeding ground found at the areas where the expressway will traverse.

2. Terrestrial Ecosystems

a. Introduction

288. The implementation of the Ben Luc - Long Thanh Expressway Project may cause adverse impacts on the terrestrial ecosystems in the project area. To obtain baseline data and information for impact assessment and proposal of mitigation measures for the negative impacts from May to August 2009 the EIA Team has conducted data collection and field surveys at the planned project right of way (ROW) and surrounding area. The contents of study on the terrestrial ecology are given below.

(i) Divide all the length of the project’s alignment into sections: a) Section 1: Project’s alignment in Ben Luc and Can Giuoc districts of Long An Province; b) Section 2: Project’s alignment in Binh Chanh district of Ho Chi Minh City; c) Section 3: Project’s alignment in Nha Be district of Ho Chi Minh City; d) Section 4: Project’s alignment in Can Gio district of Ho Chi Minh City; e) Section 5: Project’s alignment in Nhon Trach district of Dong Nai Province; f) Section 6: Project’s alignment in Long Thanh district of Dong Nai Province

(ii) Collect maps and concerned documents related to flora, fauna and environmental factors in 6 sections: Ben Luc, Can Guoc districts of Long An province (Section 1); Binh Chanh, Nha Be, Can Gio districts of Ho Chi Minh City (Sections 2, 3, 4); Nhon Trach and Long Thanh districts of Dong Nai province (Sections 5, 6)

(iii) Conduct field survey at an area with 500m width along the proposed alignment in a length of 58 km from My Yen commune of Ben Luc district (Section 1) to Phuoc Thai commune of Long Thanh district (Section 6).

(iv) In each section the following aspects of ecological study were conducted: a) Remark and identify the habitats; b) Identify common and important flora, fauna species; c) Note abundance of species; d) Identify vegetation coverage; e) Interview local farmers about fauna species occurring in study area; note on present land use; agricultural aquacultural and other economic activities.

(v) Identify unknown species in the laboratory (vi) Prepare lists of vegetation species and wild animal species recorded at the study

area.

123

(vii) Assessment of value of each ecological component and ecological value in the project area. The suggested criteria for this assessment are provided in Table IV.37.

Table IV.37: Description of Habitat Assessment Criteria

Criteria Description

Naturalness Truly natural habitats (i.e. not modified by human activities) are usually highly valued. Generally, those habitats less modified will tend to be rated higher.

Size In general larger area of habitat(s) shall be more valuable than smaller ones, all else being equal.

Diversity The more diverse the species assemblages and communities of a site, the higher is its conservation value.

Rarity Rarity can apply to habitats as well as species. The presence of one or more rare habitats and species will give a site higher value than those without rarity.

Re-creatability Habitats which are difficult to be re-created naturally or artificially are usually valued higher.

Fragmentation In general the more fragmented habitat, the lower is its value. The value of a habitat increases if it lies in close proximity and/or links functionally to a highly valued habitat of any type.

Potential value

Certain sites, through appropriate management or natural processes, may eventually develop a nature conservation interest substantially greater than that existing at present. Factors limiting such potential being achieved shall be noted.

Nursery/breeding ground Such areas are very important for the regeneration and long term survival of many organisms and their populations

Age Ancient natural or semi-natural habitats are normally highly valued. For some habitats such as woodlands, older ones are normally valued much higher than recent ones.

Abundance/Richness of wildlife In general sites supporting more wildlife will be rated higher.

Summary Score Taking into account criteria listed above, each habitat is assigned a sensitivity rating from low-high

(viii) Identify any ecologically significant species occurring in the survey area.

Significant species include: a) Locally, regionally or internationally rare/endangered species; b) Species protected under national or international legislation; c) Species of economic/cultural significance.

(ix) Conduct a specific study on the present biological resources and biodiversity at the project's ROW ans surrounding area in Binh Khanh commune, located in the Transition Zone and the Can Gio Mangrove Biosphere Reserve, which is one of most sensitive ecological zones at near the whole project alignment. Collect legal documents and master plan related to development and protection of Can Gio district. The obtained results in terrestrial ecological study are summarized below

b. Terrestrial Habitats in the Study Area

289. The surveys along the proposed alignment of the expressway from May to August 2009 have found the following types of habitats. Some images of types of habitats are shown in Figure IV.6.

124

i. Riparian Corridors

290. The vegetation corridors along the Soai Rap, Long Tau and Thi Vai rivers were affected by the process of urbanization in the recent 20 years. The width of vegetation corridors are being narrowed by change into aquacultural, agricultural or industrial lands. 291. Regarding flora, on riparian corridors, where there are residential sites, habors and industrial zones, riparian vegetations were destroyed, and replace by bare lands or concrete bank. There are some planted trees like Coconuts, Eucalyptus, Acacia trees and some shady trees. In residential sites, harbors or industrial zones, some sections of riparian remain natural vegetations.The dominant associations are Nypa palm (Nypa frutican) and Sonneratia (Sonneratia caseolaris) in brackish water ecosystem. Towards to the end of the proposed alignment in high saline water ecosystem at the Long Tau river in Nhon Trach district (Section 5) Nypa fruticans and Sonneratia caseolaris associations are gradually replaced by typical species of mangrove forest with some dominant species as Rhizophora apiculata. Avicennia alba. Excoecarta agallocha. 292. Regarding fauna, this community is much narrowed, but it is a habitat of some animal species such as Passer montanus, Centropus sinensis, Hirundo rustica, Pycnonotus jocosus (Birds), Bufo melanostictus, Rana rugulosa, Trimeresurus albolabris, Xenochrophis piscator (Amphibians and Reptiles). In floodplains of river banks there are habitats of Periophthalmus schlosseri (fish) and some economic value fish and crabs species.

ii. Canal Corridors

293. In Sections 2, 3 and 4 of the proposed alignment in Binh Chanh, Nha Be, Can Gio districts and in a part of Section 5 (Nhon Trach district) there are a dense network of canals. The vegetations along these canals have been impacted by the growths of agriculture, aquaculture and urban areas. Almost these habitats are 5m to 20m width. The continuance is low and fragmentation is high. 294. The structure of these canals habitats are the same as in the riparian habitats where there are residential sites, vegetations were destroyed, and replace by bare lands or aqua-agricultural lands. Some farmers still kept a narrow strip of natural vegetations along these canals and some farmers planted Coconuts, Eucalyptus, Acacia trees and some shady trees. 295. On canal corridors, where there are not residential sites some strips of natural vegetations remain. The dominant associations in these corridors are Nypa fruticans, Sonneratia caseolaris, Aglaodorum griffithii, and Derris trifolia in brackish water ecosystem. At Sections 5 and 6 of the project alignment, in saline water ecosystem in Nhon Trach and Long Thanh districts, Nypa fruticans and Sonneratia caseolaris, Aglaodorum griffithii, Derris trifolia associations are replaced by species of mangrove forest with some dominant species as Rhizophora apiculata, Avicennia alba and Excoecarta agallocha. 296. At these habitats the common fauna species include Passer montanus, Centropus sinensis, Hirundo rustica, Pycnonotus jocosus, some amphibia and reptiles as Bufo melanostictus, Rana rugulosa, Trimeresurus albolabris, Xenochrophis piscator; and Periophthalmus schlosseri fish are commonly found.

iii. Mangrove Forests

297. Results from the field survey in Sections 4 (Can Gio district) 5 and 6 (Nhon Trach and Long Thanh districts) indicate that:

125

(i) The project alignment at Binh Khanh commune in Can Gio districtt, where is located the Transition Zone of Can Gio Biosphere Reserve, does not pass through any mangrove forests. In this commune, only some strips of Nipa palm along canals will be encroached on by the project ROW.

(ii) The proposed alignment of the expressway goes through a mangrove forest located on both sides of the Thi Vai river (at the planned Thi Vai bridge), where it is located outside of the Biosphere Reserve. This forest was replanted 2-3 decades ago. Along the Thi Vai river in the width of 2.0 km and the length of over 45km, from the original point about 2 Km upstream of the planned Thi Vai bridge to the river mouth of the planned Thi Vai bridge, the present area of mangrove forests occupies about 40% (3,500 – 3,700ha), the remaining area being surface water, saline swamps ports, aquacultural ponds and industrial zones. About 2,200 ha of mangrove forests occur in Nhon Trach and Long Thanh district (1,200 ha at Nhon Trach district and 1,000 ha at Long Thanh district). The remaining forest areas belong to Can Gio district, Tan Thanh district and Ba Ria town. At the area of the planned Thi Vai bridge there are about 12.3 ha of forest (if the width of bridge or viaduct is 56 m as designed in the FS report). From the result of the field survey in this EIA study over 30 vegetation species in this area were identified, but the most common one is Rhizophora apiculata, the remaining species belong to Phoenix species, Soneratia caseolaris, Avicennia alba, A. officinalis, Acantus ebracteatus, Acrostichum aureum…species. The project will not construct 2 approach roads connecting the Thi Vai bridge to 2 sites, but 2 approach viaducts will be constructed, so the area of mangrove forest to be cleared for construction of viaducts will be only some thousands m2 to one ha for construction of viaduct pillars (detailed area may be only exactly determined during construction phase). Along the alignment mangrove forests are found only at the Thi Vai river banks. At other sections (Can Gio, Binh Chanh districts) along the river banks mangrove trees (mainly Nipa palms, Sonneratia, and some grass trees: Acanthus, Cyperus, and Paspalum species grow thinly. Therefore, area of mangrove trees to be cleared at other sections are small (see Chapter V) and it may be exactly determined only during the construction phase at each site.

298. Structure of mangrove forest at the Thi Vai river is simple: there is a layer of wood trees with 12 – 17m height and stem diameter (DBH) is about 5cm - 17cm, (average DHB is about 12cm). Density of trees is about 100 – 5,000 trees per hectare, depending on location: it is high 3,000 - 5,000 trees/ha) at the Western bank (Phuoc An commune – Nhon Trach district) and low (100 – 200 trees/ha) at the Eastern bank (Phuoc Thai commune – Long Thanh district). Rhizophora apiculata occurring at 90% in the total species number. Outside the boundary of this forest closest to river banks, some plants such as Avicennia alba, Excoecarta agallocha grow well. Towards upstream of the Thi Vai river at brackish water area, some native plants such as Nypa fruticans, Sonneratia caseolaris, Aglaodorum griffithii, Derris trifolia, Acrostichum aureum are commonly found. 299. Birds are commonly found at the mangrove forest at the Thi Vai river. Some common birds are Passer montanus, Ardeola bacchus, Centropus sinensis, Hirundo rustica, Pycnonotus jocosus, Streptopelia chinensis, Porzana pusilla.

iv. Paddy Fields and Upland Fields

300. These habitats occur in the whole sections of the project alignment from Ben Luc, Can Giuoc, Binh Chanh, Nhon Trach districts and Binh Khanh commune of Can Gio district. Composition of species are simple, besides rice, some natural grasses grow such as Ludwidgia adscendens, Ludwidgia octovalvis, Ipomoea aquatica, Cynodon dactylum, Eragrostis pilosa,

126

Echinochloa crus-galli, Eleusine indica, and some representatives of Cyperus. At present, the area of paddy fields is reduced by urbanization and development of industrial parks. In fallow paddy fields, Cyperus malaccensis and Echinochloa crus-galli associations appear. 301. At Section 5 along local road No. 19 in Nhon Trach District, on high elevation, there are upland fields with tapioca (Manihot esculenta). The soil is poor in fertility and has no irrigation system. 302. Some animal species are observed rarely. They are Egretta garzetta, Passer montanus, Centropus sinensis (birds), Bufo melanostictus, Rana rugulosa, Xenochrophis piscator (amphibians and reptiles).

v. Aquacultural Land and Ponds

303. Natural ponds are not common in the study area. Almost al ponds are dug for shrimps and fish cultures. They are located mainly at wetland area in districts of Nha Be (Section 3), Can Gio (Section 4), a part of Binh Chanh (Section 2), Nhon Trach (Section 5) and Long Thanh (Section 6). There are few plants species growing around ponds due to high soil salinity and/or acidity. The species of Paspalum vaginatum, Pluchea indica, Acrostichum aureum, Cyperus malaccensis, Scirpus grossus, Scirpus littoralis are commonly found. 304. At this area some bird species of Egretta garzetta, Passer montanus, Alcedo atthis, Hoplobatrachus rugulosus, and some reptile and amphibian species as Bufo melanostictus, Xenochrophis piscator may be found.

vi. Gardens

305. Gardens are located in all communes in the whole study area, but they are more common in Sections 1 (Ben Luc), 2 (Binh Chanh), 5 (Nhon Trach) and 6 (Long Thanh). A typical structure of these habitats includes a house with some fruit trees, wood trees and shady trees planted around. The common fruit trees are Cocos nucifera, Area catechu, Mangifera sp., Psidium guiava; wood trees are Acacia auriculaeformis, Eucalyptus tereticornis, shady trees are Terminalia catappa, Muntingia calabura, Samanea samam. 306. Common species of Passer montanus, Centropus sinensis, Bufo melanostictus, Rana rugulosa, Trimeresurus albolabris, and Xenochrophis piscator are found at this habitat.

vii. Forestry Gardens

307. There are only small forest plantations of under 2 hectares area. They are mainly located on poor quality soils on high elevation land in Nhon Trach (Section 5) and Long Thanh (Section 6) districts, where it is difficult to irrigate or it is not suitable for planting food crops. Common planted forest trees are Acacia auriculaeformis, Eucalyptus tereticornis and rubber tree (Hevea Brasiliensis). 308. Some species of birds Passer montanus, Centropus sinensis, Trimeresurus albolabris, Dicrurus paradiseus, and Pycnonotus jocosus are found in this habitat. Amphibia and reptiles such as Trimeresurus albolabris, Elaphe radiata, Mabuya longicaudata, Mabuya multifasciata, Polypedates leucomystax, Rana guentheri may be found.

viii. Residential Land

309. Residential areas are located along existing roads and canals. Vegetations in these areas include fruit trees, shady trees and ornamental plants. Shady trees include Acacia

127

auriculaeformis, Eucalyptus tereticornis, Terminalia catappa, Samanea samam, Muntingia calabura, Peltophorum pterocarpum, Delonix regia, Ceiba pentandra, Dipterocarpus alatus, Khaya senegalensis. Fruit trees include Cocos nucifera, Area catechu; Ornamental trees include Hibicus rosa-sinensis, Bougainvillea brasiliensis, Ixora balansae. 310. Wild animal species are observed rarely. The only common species is Passer montanus.

x. Flora and Fauna Species at the Project ROW

312. The results of the survey in May to August 2009 conducted by the Project Environmental Team show that in the study area (about 500 meters in width along the Project alignment from Ben Luc district to Long Thanh district), 83 vegetation species (Appendix IV.4.1) and 19 common wild animal species (Appendix IV.4.2) were identified. There are no endangered species listed in the Vietnam Red Book (2000). Biodiversity (area, density and number of vegetation and wild animal species) is not high at almost all sections, except for in a mangrove forest at the Thi Vai river. Mangrove forest is not grown at Binh Khanh commune, although Can Gio district is a location in the Biosphere Reserve.

xi. Taxon of Flora

313. The field surveys from May to August 2009 at the proposed Project alignment have identified 148 species of plants of 58 families (Table IV.39).

3. Natural Protected Areas

317. Within a distance of 30km from the project alignment there is one natural protected site: Can Gio Protected Mangrove Forest (Official name of Vietnam) or Can Gio Biosphere Reserve (name given by UNESCO). Closest direct distance from the project alignment to the boundary of the core zone of this Bioshere Reserve is 12.2 Km, by road is over 15.0 Km. Closest direct distance from the project alignment to the boundary of the buffer zone of Biosphere Reserve is 7.5 Km, by road is 9.9 Km. The project alignment traverses only the transition zone of this Biosphere Reserve. Total length of the alignment passing the transition zone is 6,000 m.

130

a. Profile of Can Gio Protected Mangrove Forest

318. Can Gio Protected Mangrove Forest is located in Can Gio district (formerly Duyen Hai district), in the territory of Ho Chi Minh City. This is a region of estuarine tidal mud flats, where the rivers such as Vam Co, Sai Gon and Dong Nai pour water to the sea. Can Gio district is of a low, muddy and continuously variable terrain with numerous canals, creeks and tributary rivers. It borders Nha Be district in the North, Tan Thanh district of Ba Ria – Vung Tau province in the East, the East Sea in the South and Tien Giang and Long An provinces in the West. 319. In 1922, the French planned and reserved 4,500 ha of mangrove forests in Can Gio for prevention of storms and soil erosion, and a reserve for exploitation of wood and firewood. 320. In 1964, the US Army started the destruction campaigns using chemical weapons, i.e. herbicides (Agent Orange, Agent Blue and others). In the period of 1965 to 1970, US aircrafts sprayed defoliants many times which destroyed large area of Can Gio mangrove forest. The forest was mostly degraded and exhausted. 321. After the Liberation (1975), in 1978, Can Gio mangrove forest were given to Ho Chi Minh City with 34,468 ha, including 4,500 ha of Nipa palm, 10,000 ha of chapped mud soil and 5,588 ha of former forested land. The remainder included denuded vegetation covers of bushes and clumps with the coverage of less than 40%. In 1979 the People Committee (PC) of Ho Chi Minh City launched a campaign for reforestation of Can Gio forests in order to create a “green lung” for the city. 322. In five years from 1986 to 1990, the PC of Ho Chi Minh City allotted land to 23 forestation yards and farms. Can Gio was then planned as a coastal protective forest under Decision 173/CT dated 29/ May /1991 by Prime Minister. On 02 February 2000, the Management Board of Can Gio Protected Mangrove Forest was established under Decision 169/QD-UB-CNN by the PC of Ho Chi Minh City. At present, this agency includes 96 staff who are in charge of controlling 36,997 ha of forest. 323. On 21 January 2000 the UNESCO Secretary General signed a decision, designating inclusion of Can Gio Mangrove Forest into the World Network of Biosphere Reserves. From this time Can Gio mangrove forest, the first one of Vietnam, became a member of the worldwide network of 368 biosphere reserves.

b. Zoning of the Can Gio Biosphere Reverve

324. According to the official information of UNESCO (Vietnam's Biosphere Reserves - Laboratories for Sustainable Development, 2008) and data from the Southern Forest Planning Institute (2009) the zoning of "Can Gio Bioshere Reserve is as follows.

(i) Core Zone occupied 4,721 ha covered the Southern part of Tam Thon Hiep, Western part of Thanh An and Northeastern part of Long Hoa commune with 6 sub-zones numbered 3, 4b, 6, 11, 12 and 13. According to UNESCO and the Southern Forest Planning Institute, priority is given to use of the core zone for scientific studies, particularly comparative studies and researches into sustainability and ability of genetic biodiversity restoration, into adaptation of the biota changed by human influences. The relevance of zoning and function of biosphere reserves and the national objectives of sustainable development regulated by UNESCO are presented in Table IV.40.

(ii) Buffer Zone: occupied over 37,393 ha, covered Northern part of Tam Thon Hiep, Eastern part of Thanh An, Eastern part of An Thoi Dong and Ly Nhon and

131

Southwestern part of Long Hoa commune with 18 sub-zones and 3,800 ha of water. In this zone, limited forest exploitation is permitted on the principles of preservation of resources, biodiversity and ecological balance. In fact, models of forestation together aquaculture (snail, shell-fish, crab, and fish) at small or family scale will be maintained in order to secure local people’s income.

(iii) Transition Zone: covered all area of Binh Khanh commune, Western parts of An Thoi Dong and Ly Nhon communes, all area of Can Thanh Town with over 29,310ha. According to UNESCO in the transition zone of biosphere reserve the economic objective are "to develop urban areas, industrial zone and economic development to meet the demand of local and national".

Source: UNESCO – MAB, Operation of Using Biosphere Reserves as Learning Laboratory for Sustainable Development, 2008 (Figure IV.8.) 325. According to the information of the Can Gio Mangrove Management Board and the Section of Natural Resource and Environment of the district in this transition zone all kinds of transport (highway, road, and port), agriculture, aquaculture, urban development projects are permitted to be developed. 326. It is clear that a section of the expressway connecting the Nha Be river to Long Tau river across Binh Khanh commune was included in the Master Plan of Ho Chi Minh City. 327. With above information on the zoning of the Can Gio Biosphere Reserve , the alignment selected for the Ben Luc - Long Thanh expressway will not cross over Can Gio mangrove forest due to it being located in the North of Binh Khanh commune about 10km from the forest. Therefore, this project and other infrastructural projects in Binh Khanh Commune comply with the Vietnam' Laws on Forest Protection and Development and Biodiversity and the UNESCO Regulation. 328. This project alignment is accepted by the Management Board of Can Gio Protected Forest (Letter N126/ CV BQL dated 29 July 2009) and the Can Gio District PC (Notice: 622/ UBND dated 10 June 2009).

c. Biodiversity of Can Gio Mangrove Forest

329. After 30 years of rehabilitation, Can Gio mangrove forest has now returned to a green state. At present, the total area of forest is 38,660 ha, occupying 54.16% of the total area of the district. The total planted forests include 34,440 ha of Rhizophora apiculata, 715 ha of eucalyptus, 280 ha of Nipa palm, 18 ha of Avicenna, 68ha of Rhizophora mucronata, 99ha of Sindora maritima, 638ha of Ceriops spp. and the remaining area is other species. Studies of Vien Ngoc Nam et al discovered 157 vegetation species of 76 families, including typical species of saline wetlands such as Rhizophora spp., Nipa palm, Avicennia spp., Sonneratia spp., Bruguiera, Acanthus etc. 330. Together with the recovery of the vegetation carpet, the fauna in Can Gio biosphere reserve has developed in numbers of species and individuals in the core zone of the Bioshere Reserve. 331. As for aquatic creatures, the Environmental Protection Center (VESDEC) of VESDI (2000, 2009) has identified 90-180 phytoplankton species of 6 phyla, depending on seasons and locations, 26-51 zooplankton species, 36-50 zoobenthos species such as shrimp, crab and shell-fish. 137 fish species with economically valuable ones such as catfish, Lates calcafier were identified by Hoang Duc Dat and others (1997). 332. The study by Nguyen Ngoc Sang, the Institute for Tropical Biology, from September 2006 to March 2007 discovered other 9 amphibian and reptile species (Occidozyra martensii, Polypedates dennystii, hemidactyctylus garnoti, Calotes mystaceus, Ahaetulla nasuta, A. prasina, Enhydris enhydris, Ptyas korros, Nija nija). However, there is no reptile species in this region listed in the Vietnam Red Book (2000). 333. Tidal mud flats and sand dunes in the biosphere reserve are the vital habitats of 145 coastal bird species. A report by the ADB (1999) recorded typical bird species such as Tringa glareola, T. totanus, Actitis hypoleucos, Pluvialis squatarola, Charadrius mongolus, and Himantopus himantopus. At present, they are very rarely observed in the Can Gio forest. 334. Some endangered bird species have been observed in Can Gio with low frequency; those include Tringa guttifer, Limnodromus semipalmatus, Pelecanus philippensis and Mycteria leucocephala (Tordoff et al. 2002.). At present, they have almost disappeared in this Biosphere Reserve. 335. As for wild animals, 19 mammal species including monkey, wild board, otter, wild cats, etc. are recorded in the core and buffer zones. Besides monkey (Macaca fascicularis) with about 500 individuals, the other mammal animal species are very rarely observed.

d. Biodiversity at the Project’s ROW at Can Gio District

336. The proposed alignment of Ben Luc – Long Thanh Expressway will across the Northern part of Binh Khanh commune in Can Gio district. Binh Khanh commune is located in the transition zone, outside of the mangrove forest. During recent 30 years there was not an area of forest planted in this commune. At present, the commune is a main rice cultivation area of Can Gio district. Large part of the commune area is used for aquaculture, port and resident sites (see land use map scale 1:50,000 in this chapter and Google map in Chapter V). 337. According to the results of the field surveys conducted by the EIA Team in May – August 2009, in Binh Khanh the main vegetation species are rice, various species of brush trees. Some

134

thin belts of Nipa palm, Sonneratia spp. along the Nha Be, Long Tau rivers and canals occur. There are some species of wild animals as frogs, snakes, and birds but they are rarely found. There is not a species belonging to the Vietnam Red Book (detailed data on vegetation and animal species found in Binh Khanh commune are shown Chapter V of this EIA Report.

To obtain preliminary information on the present socio-economic conditions of the project affected households (PAHs) the EIA Team has conducted interview with 50 households in 7 districts at the the Project area: Ben Luc, Can Giuoc (Long An province), Binh Chanh, Nha Be, Can Gio (Ho Chi Minh City), Nhon Trach, Long Thanh (Dong Nai province. The obtained results from the filled questionnaires were synthesized and assessed as follows:

a. Interviewers’ Information

403. Through survey on 50 representative PAHs in the affected area of the project, there are 63.33% of male, 36.67% of female. All of them belong to the ethnic majority of Kinh. There are a variety of religion component including Buddhism (46.67%), Cao Dai Religion (16.67%), other religions accounting for 36.67%.

The collected information shows that education level in different regions greatly differs so that land acquisition and compensation need to be handled carefully and have meticulous related paperwork for households having a low education level.

c. Main Income

405. The main income of the interviewed households at the Project communes are as follows: a) Aquaculture (17%); b) Trading (35%); c) Office staff (24%); d) Animal husbandry (12%); e) Gardening (12%); f) Forestry (0%). 406. Through the socio-economic conditions collected from 50 typical households affected by the project, the number of households with main income from salary and business is much more than that from aquaculture, animal husbandry and gardening. According to the survey’s results, although at Ben Luc, Can Giuoc, Binh Chanh and Nhon Trach districts have a quite large area of rice cultivation, most of output is used for households and animal raising. 407. Monthly average income of 50 households interviewed have 6.67% of 1-2 million/month. 16.67% of 2-3million/month. 26.67% of 3-5 million/month. 30.00% of 5-10 million/month of and 20.00% of 10 million/month and none under 1 million/month.

According to survey’s results, 51.28% of households use rain-water source, 15.38% of them use rain-water source, 25.64 of them use tap-water source and 7.69% of them use dug-well water source. Almost all households in Nha Be and Can Gio use tap-water with price about VND 50.000/m3 (of over 20 times higher than the average price of clean water in the urban area). Groundwater cannot be used for households in Can Gio, whereas in Nha Be water from drilled-well water can be used for bathing and washing mainly, water for cooking and drinking is from water-tap or water supply tankers. Concerning water quality in 50 households interviewed, 36.67% of them think that water source is good, 43.33% of them think that it is medium, 3.33% of them think that it is bad and the rest (16.67%) have no comments.

ii. Waste Collection, Disposal and Treatment

410. There are 43.33% of households said that waste are collected and treated by collecting system of commune or company; 30.00% of them dug to bury waste; 26.67% of them collect waste and burn. At the crowded population site including Binh Chanh, Nha Be, Long Thanh and a part of Can Gio, there is collecting waste system. At the remaining

148

districts in thinly populated sites, almost waste are collected and treated at households by digging holes to bury making fertilizers for gardening or burning.

iii. Sewage Drainage System

411. In 50 households interviewed. 23.33% of them have public drainage water system of commune; 33.33% of them discharges waste water in canal system, the rest of them let waste water overflow and absorb by soil (43.33%). Almost all areas that alignment will pass have not had sewage drainage system, accept for some area close to Highways 1 and 51 or some dense population sites.

f. Requirements of PAHs in Environmental Management of the Project

412. According to the results from interview on the representative PAHs the project owner is required to have effective measures in environment protection, particularly dust, noise and vibration mitigation during the project construction activities. The project should ensure a good drainage system, not make difficulties for people in daily life and production, be good at labour resource management that does not affect to public security and spiritual life of the local people. Moreover, the PAHs require that the policies on land acquisition and compensation should be reasonable and the investors should create policies on employments, using local labour resource.

V ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

A. Approach to Screening of Environmental Impacts

413. The approach to screening of environmental impacts for the Project follows the guidance contained in a range of documents relevant to environmental assessment of road projects including the following key documents:

(i) ADB's Safeguard Policy Statement (SPS), 2009 (ii) IFC Environmental, Health and Safety Guidelines, Toll Roads, April, 2007 (iii) Environmental Guidelines for Selected Infrastructure Projects (Highways and

Roads, ADB, 1993) (iv) Vietnam Guidelines for EIA (Decision N21/ 2008/QĐ–CP, Circular

05/2008/BTNMT) (v) Vietnam Technical Guideline for EIA for Transport Project, 2002 (vi) World Bank (WB) Environmental Assessment Sourcebook, Vol.2, Guideline

for Environmental Assessment for Roads and Highways Projects,1991. In this EIA the document (i) is most important to be followed. 414. Issues for inclusion in the environmental screening were identified through the EIA scoping process. Based on knowledge of the existing environment, the project characteristics and experience with the typical potential impacts of road and highway development, those issues for which environmental impacts were likely to occur were identified. 415. A range of technical investigations was carried out for each of the identified environmental issues to determine the effect that the project may have on a particular characteristics of the surrounding environment. Potential impacts were categorized according to the project phases, i.e. pre-construction, construction or operation, in which they occurred. Impacts with the potential to occur during decommissioning or as a result of accidents or unforeseen conditions were also identified. This process was carried out to ensure mitigation measures could be developed which were appropriate to each project phases. 416. For those identified impacts for which it was possible and/or necessary, mitigation measures were developed. The following hierarchy of mitigation strategies (from highest priority to lowest priority) was implemented:

(i) Avoiding the impact (e.g. recommending measures to be implemented during detailed design to avoid physical impact on areas of wetland ecosystem, particularly mangroves);

(ii) Minimizing the impact (e.g. installing wastewater treatment systems to treat effluent before discharge);

(iii) Rectifying the impact (e.g. rehabilitating areas where mangroves have been destroyed as a result of the project); or

(iv) Compensating for the impact (e.g., providing financial compensation for those who will lose land as part of the Project).

417. Cumulative impacts of the project were considered separately. Cumulative impacts are complex impacts that arise from the Project acting in combination with other past, present and future activities and development. Cumulative impacts can be:

(i) Additive: impacts that result from the combined effect of a number of smaller impacts

150

(ii) Compensatory: impacts that occur when the effects of one project or activity act to offset the effects of another

(iii) Synergistic: impacts that result when smaller impacts combine to create different or more significant impacts – the overall impact is greater than the sum of the individual impacts

(iv) Masking: impacts of multiple projects overlap in a way that there is no perceived additional impact, usually for an initial period of time after which impacts become one of the other types of cumulative impacts

Classification of Environmental Impacts of the Project 418. In this EIA report, (negative) environmental impacts of the Project are classified into 5 levels in accordance with international classifications with specific conditions of the project site taken into account.

(i) No impact: means unapparent and negligible influence on the natural and socio-economic environments at the project site and its surroundings.

(ii) Minor impact (or small impact): means slight influence on a small portion of population (in this projects: some households at each commune) or a small area of natural ecosystems (for example, less than 1.0 ha at each site).

(iii) Intermediate (or medium impact): means influence on a portion of population or a relatively large area of natural ecosystems (for example 1.0 – 10.0 ha of forest at each sites).

(iv) Major impact: means significant influence on a large portion of population (various communes inside and around the project ROW) or a large area of natural ecosystems (more than 10.0 ha each site in this project).

(v) Unknown impact: means influence that is unpredictable as lacking information or data (for instance, impacts due to sea level rise, earthquake, heavy flood, etc in this project area).

Each impact is also determined as short-term or long-term, recoverable or irrecoverable, unmitigable or mitigable. B. Impacts in the Pre-Construction Stage and Mitigation Measures

419. In the Pre-Construction Stage the main activities of the project are:

(i) Study to select best alignment of the expressway. (ii) Further investigation on geo-engineering to detailed design the road and

bridge. (iii) Design roads, bridges and other technical facilities. (iv) Acquire land, relocate houses and infrastructural facilities; remove vegetation

covers within the project ROW for construction of road, bridges and other technical facilities.

(v) Implement resettlement action plan (RAP). (vi) Land clearing for preparation of « clean area » for road and bridge

construction.

1. Physical Environment

420. From the above identified activities it may be found that in the pre-construction phase, the physical environment, particularly land, water, air environment may be affected. However, the impacts on the physical environment are expected as minor. 421. The geo-engineering investigation by drilling may cause adverse impacts on groundwater quality and air quality. This impact is expected as minor and mitigable.

151

422. During site clearance vegetation cover within the project's ROW will be cleared. This activity not only impacts on local biological resource, which is assessed in the next Section V.B.2, but also on the physical environment. The sections where large area of trees will be cleared are Section 3 (Nha Be district), Section 4 (Can Gio district), Section 5 (Nhon Trach district) and Section 6 (Long Thanh district). The main vegetation species to be cleared are Nipa palm, brackish water shrubs trees (in Sections 3, 4) and Nipa palm, Sonneratia sp., Rhizophora spp. (in Sections 4, 5 and 6) 423. From observation during field surveys it may be estimated that at Sections 3 and 4 total weight of trees to be cleared may be 50 T (mainly at canal and river banks). It may be over 50 T in Section 5 (mainly at the Western Thi Vai river bank: maximum 0.5ha *5,000 trees/ha * 20kg/tree) and over 20 T in Section 6 (mainly at the Eastern Thi Vai river bank: maximum 0.5ha * 2,000trees/ha * 20kg/tree). Amount of vegetation to be cleared at other sections is small. 424. In case of disposal of this amount of biological waste (roots, trunks, branches, leaves of trees) into the surrounded canals, river or land the following environmental impacts may be expected.

(i) water pollution by organic matters (ii) air pollution by odor generated from decaying products (iii) obstruction of waterway transport (iv) aesthetic impact

425. To avoid the above predicted impacts on the physical environment the following countermeasures will be implemented by each Site Clearance Team.

(i) Disposal of cut vegetation into canals, rivers is prohibited. (ii) At each construction team properly collect the cut trees into a site and allow

local residents to take out for their use for construction materials or fuel. (iii) Burning the cut trees may be done only in some limited cases with the

following conditions: - Small amount of the cut trees (less than 100kg at a time) shall be burned in accordance with national and local regulations - Location of burning place is far (over 500m) from residential areas, and other sensitive receptors such as schools, hospital, culturally significant sites, etc. fuel storage sites, and over 200m from construction worker camp. - With available and sufficient fire prevention devices and manpower for fire extinguishing and for ensuring that surrounding vegetation are protected from fire. - Will not cause nuisance and safety risks to sensitive receptors (houses, schools, etc.) and road users in the surrounding areas.

2. Biological Environment

426. To clearly predict the impacts of land acquisition and site clearance for road and bridge construction, the EIA Team conducted detailed surveys for 3 months from mid - May to mid - August 2009 on the present ecological conditions, particularly, terrestrial habitats at the project ROW and the surrounding areas with the width and the length of the study area are 500m x 60,000m. 427. To easily identify ecological characteristics of the project area, the whole length of the alignment is divided into 6 sections according to the district's boundaries (see Chapter III). At each section characteristics of habitats, included flora and fauna were recorded. Combining the results of the field surveys, present land use map and analysis of Google maps the following prediction on ecological impacts of land clearance in the pre-construction phase may be given.

152

a. Ecological Impacts Caused by Land Clearance and Vegetation Removal at Section 1: From Starting Point to Ong Com Canal (Ben Luc and Can Giuoc District Section) and Mitigation Measures

428. In this section only two habitats are dominant: paddy fields, occupying about 88% of the total length of the section. Gardens and residential land, occupying about (12%) of the length of the section (Figure V.1). The common vegetation species are shown in Table V.1 and wild animal species - in Table V.2. 429. All wild animal species are commonly found in the downstream region of the Dong Nai - Sai Gon river basin.

430. From the above information the impact caused by land clearance and vegetation removal in this section is assessed as negative and long - term. However, the area of vegetation removal is small, the vegetation species to be cleared are rice, vegetables, sugar canes, some common fruit trees, wild grass species and eucalyptus. Total area of wild trees at the river/canal bank to be cleared is less than 1,000m2 at each site. There are no wild animal species classified as rare or endangered, this impacts is assessed as minor. 431. The impact can be mitigated by (i) do not cut vegetation carpet outside of the project ROW, (ii) do not fill up canals within the project ROW and the surrounding ponds and wetland area. Replanting of the lost vegetation area at this section is not necessary.

b. Ecological Impacts Caused by Land Clearance and Vegetation Removal at Section 2: from Ong Com Canal to Ba Lao Canal (Binh Chanh District)

432. In this section dominant habitats may be identified with their percentages in the total length of the section as follows: paddy fields (47%), gardens and residential land (36%), aquaculture lands/ponds (7%), riparian/canal corridors (3%), wetlands (4%), (Figure V.2). The common vegetation species are listed in Table V.3 and wild animal species - Table V.4.

433. From the above data the impacts caused by vegetation removal on the existing natural habitats are assessed as negative and long-term. However, due to the area of the mangrove trees to be cleared being small (about 3,000 m2 in total at all river and canal banks and wetland area), the main mangrove species are Nipa fruticants and Sonneration caseolaris, which is very common tree in the project districts, and there are no vegetation and animal species which are rare or endangered, this impact may be assessed as minor.

434. The impact can be mitigated by the following measures: the vegetation area along the canals shall be restored by replanting strips of mangrove trees with 50 -100 m in length on each bank and 5 -10m in width if land is available. Nipa palm may be replanted by local farmers at wetland area outside the project ROW. Total area to be replanted shall be at least equivalent to the area of mangrove to be cleared, which is about 3,000 m2). The species to be planted are Nipa palm (Nypa fruticans) and Sonneratia caseolaris. The density of trees is required as 1.5*1.5m (for Sonneratia caseolaris) and 2.5*2.5m (for Nypa fruticans). At this section and other sections replanting nipa palm at the river/canal banks is compulsory because of this vegetation has importance in soil erosion control. However, suggestion of replanting this tree in cultivation areas is not feasible and practical, due to:

(i) With the increased urbanization and infrastructural development in the provinces in the coming decades no land used for planting this tree.

(ii) In the recent decades Nipa palm has become "agricultural vegetation" but not wild species.

(iii) In difference with Rhizophora, Sonneratia its values in ecological conservation and economy is low. Therefore, when area of agricultural land will be reduced, local farmers will plant other trees which have higher economic value. In Vietnam agricultural land is private one, farmer can cultivate what trees they like, government or project can not interfere. This tendency is irrevocable at present and the future.

c. Ecological Impacts Caused by Land Clearance and Vegetation

Removal at Section 3: From Ba Lao Proposed Bridge to the Soai Rap River (Nha Be District Section) and Mitigation Measures

435. In this section dominant habitats are: paddy field (40% of the total length), aquaculture lands/ponds (13%), riparian/canal corridors (13%) and residential and garden land (14%), and waste wetland (11%) (Figure V.3). The common vegetation species are listed in Table V.5 and wild animal species are listed in Table V.6.

436. In the past, there were large waste wetlands with some plants representative of brackish water ecozone such as Nypa fruticans, Pluchea indica, and Acrostichum aureum. At present, almost all areas are used for aquaculture; some areas are used for rice cultivation, the natural wetland area to be lost to the project is small: total mangrove area at the river/canl banks to be cleared is estimated at 3,000 - 4,000 m2 (mainly at Eastern Ba Lao river bank, in which Nipa palm and grass trees: Acanthus, Acrostichum spp. are dominant). Therefore, the impacts of land clearance and vegetation removal in the project ROW to the natural ecosystem is long - term but minor. 437. To mitigate the impact the following measures could be applied

(i) restoration of the lost vegetation area a long rivers and canals by replanting of strips of mangrove trees with about 50m in width, depending on the land conditions. Ensure that the total area of mangrove to be replanted is at least equivalent to the area to be cleared at canal/river banks. The species to be planted are Nypa fructicans (with a density of 2.5*2.5m), Sonneratia caseolaris (with a density of 1.5*1.5m). At saline water areas some species of Hibiscus liliaceus, Aglaodorum griffithii and Rhizophora apiculata could be additionally planted.

(ii) do not cut trees grown outside of the project ROW; (iii) do not fill up canals, creeks, ponds and wetland area outside the project

ROW.

d. Ecological Impacts Caused by Land Clearance and Vegetation Removal at Section 4: From the Soai Rap river to the Long Tau river (Can Gio District Section)

438. The length of this section is about 6.0km. In this section the dominant habitats are: aquaculture lands/ponds (9%), riparian/canal corridors (17%), residential and gardens (3%), paddy field (42%). No forest area is found in this Section (Figure V.4). The common vegetation species are listed in Table V.7, wild animal species - Table V.8.

439. Although Can Gio district is located in the Biosphere Mangrove Reserve, Binh Khanh commune is located in its transition zone, where from the past (1975) to the present time no area of mangrove forest was planted. Therefore, there is no forest occurring at the project ROW. A part of this section of the alignment runs through canal and riparian corridors of the Soai Rap and Long Tau rivers. The impacts of land clearance and vegetation removal to the natural ecosystems are expected to be long - term but it would not be significant as the width of the lost habitats is narrow. Almost all areas of the planned ROW have been exploited for aquaculture. Some areas are used for paddy fields and residential land. So, direct impacts of the project on the Can Gio mangrove forest are not expected. 440. According to UNESCO guideline for zoning and functions of biosphere reserves (Figure IV.8, Chapter IV) in the transition zone urban and industrial parks are suggested to be developed to meet local and national demands. Therefore, development of the expressway in Binh Khanh commune located in the transition zone of Can Gio Biosphere Reserve is accepted and supported by local authority and Management Broad of Can Gio protected Mangrove Forest.

441. Even though the construction of the expressway and two big bridges (Binh Khanh and Phuoc Khanh) will cause minor impacts on the mangrove ecosystem of Can Gio, due to the area of mangrove trees to be cleared being small, all vegetation species in this section area very common in HCMC and downstream of the Dong Nai river, there are not any wild animal belonging to the Vietnam Red Book (2000). Total area of mangrove trees (mainly Nipa palm) in a length of 3,000m at the Eastern Soai Rap river where the alignment across is about 40,000 - 60,000m2. However, a viaduct will be constructed at this section area of mangrove trees to be cleared for the Soai Rap (Binh Khanh) bridge at Eastern bank is about only 10,000 m2 (for viaduct pillar construction). Area of mangrove trees to be cleared at the Western bank (in Section 3) is about 1,000 m2. Density of Nipa palm in the Eastern bank of the Soai Rap river is 20 trees/100 m2 and it is 10 trees/100 m2 at the Western bank. Total area of mangrove trees to be cleared for Long Tau (Phuoc Khanh) bridge is about 5,000 - 6,000 m2 for both river banks. Nipa palm and Sonneratia spp. are dominant along the Long Tau river. Densities of Nipa palm and Sonneratia are 20 trees/100 m2 and 10 -15 trees/100m2, respectively. Sonneratia grows only at the river banks. 442. Because of the sensitivity of Can Gio Biosphere Reserve, the following measures shall be taken to minimize the potential impacts caused by land clearance and vegetation removal for road and bridge construction. 443. During the land clearance, vegetative corridors along the rivers of Soai Rap and Long Tau as well as canals out of the ROW shall be maintained for biodiversity protection and erosion/landslide prevention. Because the risk of landslide in this zone is very high due to the expressway running on the edge of the Soai Rap river, restoration of riverside vegetation is essential. 444. An area of mangrove trees lost by the project shall be compensated by replanting of the same area of mangrove trees. The area to plant is the river bank closed to bridge construction site. At each bank of two rivers the length and width of replanted area is about 200m x 5 -10m (at 2 banks of the Long Tau river) and about 2,000m x 5 - 10m at Eastern bank of the Soai Rap river. Due to Western bank of the Soai Rap river is planned for harbour construction, replanting at this place is not suggested. Adaptable species for this purpose are listed in Table V.9.

e. Ecological Impacts Caused by Land Clearance and Vegetation

Removal at Section 5: From the Long Tau River to the Thi Vai River (Nhon Trach District Section) and Mitigation Measures

445. In this section the dominant habitats are paddy and upland field (66%), residential and garden land (7%), aquaculture lands/ponds (10%), mangrove forests (2%), canal and river corridors (3%), forestry gardens (6%) (Figure V.5). The common vegetation species are listed in Table V.10, the common wild animal species - in Table V.11. 446. Almost all this section runs through paddy fields on low land, and residential sites, a small part of the section runs through upland fields of casava (Manihot esculenta). Therefore, potential impacts of the project on the natural habitats at the western part are assessed as minor. 447. However, the end of this section runs through an area of mangrove forest at the Thi Vai river bank with about 700m in length. As mentioned in Chapter III, within Nhon Trach and Long Thanh districts, area of mangrove forests along the Thi Vai river is about 2,200 ha. Due to the two viaduct which will be constructed to connect the Thi Vai bridge to 2 sides, the area of mangrove forest to be cleared at 2 river banks may be only some thousands m2 to maximum 1.0 ha (for construction of viaduct and bridge pillars), depending on construction options. Because of density of mangrove trees and biodiversity in vegetation at the Thi Vai river banks are high, clearance of this vegetation may cause medium ecological impacts. 448. Total area of mangrove trees to be compensatively replanted at Section 5 (from the Eastern bank of the Long Tau river to Western bank of the Thi Vai river is about 8,000 m2 in maximum (3,000 m2 at the Eastern Long Tau river and 5,000 m2 at Western Thi Vai river). 449. The impact on the mangrove forest at the Thi Vai river bank can be mitigated by a compensation reforestation to assure an area of forest lost by the project will be compensated by the same area of replanted forest. The site for planting the compensational forest shall be selected based on the following criteria:

(i) it connects to the existing forest; (ii) its ecological properties and soil are good for the species to be planted; (iii) its land value is low; (iv) it is not located in any area which has been planned for other economic

sectors.

450. The species to be planted include Rhizophora apiculata, Avicennia alba, Bruguiera cylindrica, Hibiscus tiliaceus, Excoecarta agallocha, and Lumnitzera racemosa. The density is 1.5m x 1.5m (for Rhizophora apiculata).

451. The site proposed for re-forestation: the saline swamp on the right bank of the Thi Vai river that is downstream of the proposed Thi Vai bridge, adjacent to the affected forest. At present, it is poor mangrove forests. The project owner shall coordinate with the PC of Phuoc An commune of Nhon Trach district for its restoration. 452. Unit cost for planting one ha of mangrove forest at the Thi Vai river bank is estimated in Table V.12. 453. Beside a reforestation plan for compensation of the lost forest at the Thi Vai river the main measure to be used to avoid forest fragmentation and to maintain the flows in the aquatic biota in the mangrove forest, is to build a viaduct, but not a road to the bridge. Total bridge length is 3,7200m, in which length of viaduct is 3,425m.This is the first project in Vietnam to take such a measure for biodiversity protection at the coastal forest area.

455. To construct Thi Vai bridge and a road section from the river to National Road 51 a large area of mangrove forest at the Thi Vai river bank would be cut off. However, the area of forest would be lost by Thi Vai bridge construction at the Eastern bank may be only 4,000 - 5,000 m2, due to the project will not construct an approach road but a viaduct to connect the bridge with the National Road N51. Total area of mangrove forest at both banks of the Thi Vai river to be lost by the project would be maximum 1.0 ha. 456. From the above data the impacts of land clearance to the wetland ecosystems at the western part of Section 6 are predicted as long - term, irreversible, but minor. 457. In order to minimize negative impacts on the mangrove forest at the Thi Vai river bank, the project owner shall take the same measures for forest restoration as for the right bank of the Thi Vai River. Those include:

(i) Building up a viaduct of 3,425m connecting Thi Vai bridge with the junction to National Road 51.

(ii) Planting a compensational forest. 458. The area of the compensational mangrove forest shall be equal to the forest area to be lost (to be exactly measured in the construction stage). The site selected for the compensational forest is a saline swamp on the Eastern bank of the Thi Vai River that is adjacent to the bridge. The tree to be planted is Rhizophora apiculata. At present, in this place there is only a poor mangrove forest. The project owner shall negotiate with the PC of Phuoc Thai commune about the area, plan, cost and organization for that purpose.

f. Mangrove Reforestation Plan (MRF)

459. The project owner (VEC) or its PIU3 will cooperate with: Section of Forestry within Division of Agriculture of Long Thanh PC (in case of reforestation at the Thi Vai river) or Department of Agriculture and Rural Development of HCMC (in case of reforestation at HCMC), who have rich experiences in mangrove forest plantation, to prepare a MRF. 460. Contents of this MRF shall comply with the following requirements.

(i) The plan will be prepared prior commencement of construction stage. (ii) The plan shall be implemented during the construction stage. (iii) The source of funds for mangrove replanting is included in the project cost,

which is USD 570/ha for Rhizophora spp. and USD 400/ha for Nipa palm.

461. Primary components of the MRF ar suggested as follows:

(i) Objective: Replanting mangrove forest with Rhizophora apiculata to be main species. Assocated species for replanting are Avicennia Alba, Nipa fruticans, Bruguiera cylindrica, Hibiscus tiliaceus, Excoecarta agallocha, Lumnitzera racemosa.

(ii) Criteria for selection of above species are a) grows well at the local conditions of soil, topology, water quality tide and climate; b) have high ecological and or economic values; c) easy and low cost in replanting;

(iii) Criteria for site selection are a) Former area of mangrove forests, but now the mangrove trees have low density; b) Not far from the project construction site; c) have suitable natural conditions for mangrove replanting (topography, soil,

170

water, tide, sediment etc.; d) Land may be agreed by local residents or authorities for mangrove replanting (land will not be planned for industry, port or residential development; land with low cost)

(iv) From the above criteria the most suitable area to be replanted are the Thi Vai river banks (for Rhizophora) and river banks of Long Tau, Soai Rap, Can Giuoc , Ba Lao rivers, (for Nipa and Sonneratia), where there are not planned urban, port, industrial development

(v) Planting density for Rhizophora apiculata : 1.0m x 1.0m or 1.5m x 1.5m. Planting density for associated species : 2.0m x 2.0m / 3.0m x 3.0m

462. Planting technique and labour will be provided from local forestry agency and farmers who have experience in planting mangrove forest (the project owner will pay for this cost). 463. Replanting time frame is suggested in Table V.15.

3. Socio - Economic Environment

467. Socio - economic and cultural impacts caused by land acquisition and resettlement are assessed in detail and measures for impact mitigation are suggested in the Reports of Resettlement Social Study of the ADB TA 7155 -VIE, November, 2009. In this EIA Report these impacts and mitigation measures are only briefly summarized with some additional comments from the results of public consultation conducted by the EIA Team.

a. Impacting Scope of Land Acquisition and Resettlement

468. The expressway will cross over 15 communes of 7 districts of Long An, Dong Nai provinces and Ho Chi Minh City. The assessment of land acquisition impacts is made by the Resettlement Team of KEI based on satellite photos and cadastral maps of the affected communes and districts with the ROW of 54 - 73 m.

i. Impacts on Individual Households

469. The survey team of EPC - the Resettlement Team of KEI in ADB TA 7155-VIE carried out for the IOL in the period from June to late October 2009 and the results obtained are as follows:

470. There are a total of 2,558 households (HH) with 11,194 persons (186 in Long An, 1,189 in HCMC and 1,183 in Dong Nai province) would be affected; of which: there are 650 household (36 in Long An, 279 in HCMC and 335 in Dong Nai province) affected on residential land. Of these 559 plots of residential land are with houses and 91 plots without houses.

471. There are 1,908 household (149 In Long An, 910 in HCMC and 849 in Dong Nai province) affected on other lands (annual crop land, garden land, forestry etc.). There are

172

878 households (885 houses) either fully or partially affected on houses; of which 559 households (563 houses) on residential land and 319 households (322 houses) on non-residential land. Total area of affected houses need to be compensated is 99,811 m2, of which, area of partially affected houses is 2,087 m2 (20 houses), area of fully affected houses is 97,724 m2 (865 households).

472. From 559 households (563 houses), there are 493 households (495 houses: in Long An, 220 in HCMC and 247 in Dong Nai province) fully affected on houses on residential land (and 329 households (322 affected houses: 27 in Long An, 181 in HCMC and 114 in Dong Nai province) on non-residential plots.

473. From 493 household who are fully affected on houses on residential land (417 residential plots will be fully affected and 76 residential plots will be partially affected, thus, fully affected houses on these plots would be rearranged on the remaining areas), there are 354 household (12 In Long An, 169 in HCMC and 173 in Dong Nai province) with 354 houses are with the remaining residential land is less than 100 m2, thus, they have to be relocated and 139 household (16 In Long An, 51 in HCMC and 72 in Dong Nai province) with 141 houses are with the remaining residential land is equal or more than 100 m2, thus they could arrange the affected houses on the remaining area. The remaining houses will be partially affected only.

474. There are 2,558 household (185 in Long An, 1,189 in HCMC and 1,184 in Dong Nai province) are affected on annual crops and trees. Total residential affected land is 161,278 m2 (Long An province is 22,423 m2, HCMC is 65,348 m2 and Dong Nai Province is 73,507 m2). Total other affected land is 3,459,882 m2 (Long An province is 198,140 m2, HCMC is 1,658,154 m2 and Dong Nai Province is 1,603,588 m2).

475. Table V.18 below and Tables IV.33 and IV.34 (Chapter IV) describe affected population, affected land, buildings, substructures, trees, crop etc of the individual households and collective and public works.

ii. Public Assets and Works Affected by the Project

476. The public assets and works to be affected include commercial forests, rural roads, electric grids, irrigation works, etc. For instance, in Binh Khanh commune, Can Gio district, over 10,000 m2 of commercial land, about 4000 m2 of rural roads, and 1.2 km of low-voltage lines will be affected.

b. Socio-Economic Impacts to the PAHs

477. The acquisition of agriculture land, residential land, commercial land and public works for the Ben Luc - Long Thanh expressway project will cause the following negative impacts on the PAPs.

i. Loss of Agriculture Land and Socio-Economic Impacts

478. The project will temporarily or permanently acquire a large area of agriculture land. This will cause negative impacts on the local social environment. At present, based on information from local people, the total income from one (1) ha of agriculture land in the relevant districts is VND 33 - 35 million per year (2-rice crops and 1-subsidiary crop per year, in Ben Luc, Can Giuoc, Binh Chanh) or VND 20 - 25 million per year (1 rice crop and 1 subsidiary crop per year, in Can Gio) or VND 70 million per year (orchards in Nhon Trach and Long Thanh) or even VND 60 - 100 million per year (industrial shrimp culture, in Can Gio, Nhon Trach, this is however limited). Table V.19 provide information on income from agriculture and aquaculture of some households at the project’s comunes. 479. In the future (after 2020), the earning from 1 ha of agriculture land in the region is predicted at VND 40 - 50 million (rice and subsidiary crops) and more than 100 million (orchards or aquaculture). Therefore, the implementation of the project and the loss of 217.58 ha of agriculture land would cause the lost of VND 8.7 - 10.9 billion, the lost of 41.53 ha of aquaculture land would cause the lost of VND 4.15 billion in 2020.

Table V.19: Typical Agricultural Models and Annual Incomes of Farmers in the Project Area

Case 1: Mrs. Huynh Thi Anh (66 years old) and her household Address: Hamlet 6, My Yen commune, Ben Luc district, Long An province Main crops: rice, 2 crops/year, yield: 2 crops: 6.0 ton/ha; price of 1 kg of dried paddy = VND 5.000 VND, earning (expended not yet deducted) = VND 30 million/year Case 2: Mr. Nguyen Duy Thanh (64 years old) and his household Address: Hamlet 2, Binh Chanh commune, Binh Chanh district, Ho Chi Minh City Main crops: rice, 2 crops/year, area: 0.34 ha, yield: 6.0 ton/year; earning: VND 10.2 million/year Growth of snapper fish in 500 m2 pond, earning VND 100 million/year Case 3: Mr. Nguyen Van Di (47 years old) and his household Address: 519, Binh My commune, Binh Khanh district, Ho Chi Minh City Crops: rice: 7,000 m2, 1 crop/year, yield: 3 ton/crop/year. Earning: VND 10.5 million/year Aquaculture: 1,500 m2, yield: 600 - 900 kg/year, profit (expenses deducted): VND 5 - 6 million/year Case 4: Mr. Dao Van Nhon (46 years old) and his household Address: 659, Rung Sat road, Binh Thuan hamlet, Binh Khanh commune, Can Gio district, Ho Chi Minh City White shrimp culture: 11,000 m2, profit: VND 35 million/month Juvenile shrimp production: profit VND 250 - 300 million/month. Case 5: Mrs. Nguyen Thi Tam (60 years old) and her household Address: Chinh Nghia hamlet, Vinh Thanh commune, Nhon Trach district, Dong Nai province Main crops: jackfruit, mango, banana, and apricot: earning: 35 million/year on 6,000 m2. 480. The loss of agricultural earning is not big when compared with the benefits from the project in the region yet it will significantly adversely influence the livelihood of the PAHs because they earn their living mostly on agriculture and aquaculture (secondary income may be from breeding and hired work).

174

481. In addition, agricultural land loss will cause more difficulties in the affected households:

(i) The farming land of each household is approximately 3,000 – 15,000 m2, meaning that a loss of 1,000 m2 of land is equivalent to 7 – 33% of annual income from agriculture;

(ii) It is very difficult for the affected households to purchase equivalent land lots because the affected districts and provinces have no more farming land for them.

(iii) It is not easy for the PAPs to find new jobs in trade and industrial sectors because they have never trained in vocational schools. In general, farmers in the affected localities have no skill to work for industrial entities. Local handicrafts, trading and service in various communes are still under-developed, therefore, they may not provide much jobs for the PAHs.

(iv) Unemployment is almost certain for many households subject to full land acquisition. In fact, it is a matter of record that a number of farmers in various regions in Vietnam became jobless after receiving the land compensation. The impacts above are inevitable for infrastructure development projects in Vietnam, particularly expressway projects. In case of the Ben Luc - Long Thanh expressway project, the number of affected household is far lower than those of others such as Hanoi – Thai Nguyen, Hanoi - Lao Cai, and many other urban development projects.

(v) Conversely, change in land use and construction of the expressway will open various opportunities for socio-economic development of the project districts and the Southern Region of Ho Chi Minh City as it will: a) promote local industrialization, urbanization and commerce; b) create many jobs in the industry and service sectors; c) support cultural, educational and health care development of the communes and districts; d) Boost the value of land at the communes alongside the expressway.

482. Based on the analyses above, the socio-economic impacts of the project are assessed as negative and major to households which are subject to land acquisition but positive to the entire communes and districts along the expressway. Negative impacts may be mitigated by means of appropriate policies on compensation and employment support for the PAPs. (see Section below) and detailed Report of Resettlement.

ii. Loss of Houses, Historic, Cultural, Religious Building

483. Although Ben Luc - Long Thanh expressway is aligned so as to minimize encroachment upon residential area, 867 households will lose houses with a total of 91,703 m2. Most of the houses belong to class 4 (725 houses) or temporary (195 houses). There are only 4 houses of villa or class 1. Housing loss will be a major impact on the affected households. For many families, the impact is negative but the investigation by the EIA Team (with questionnaires) shows that 50% of the affected households want early compensation and site clearance, considering it a good opportunity for repairing or upgrading the existing houses or purchasing family utensils. Since the expressway alignment is selected to avoid encroachment into all historic and cultural sites, there is no building of this kind to be affected by the site clearance.

iii. Loss of Other Kinds of Land and Technical Works

484. A certain area of Nipa palm and mangrove trees (mostly in Can Gio, Nhon Trach and Long Thanh districts) will be acquired for the project. This impact is minor on the living, production and biodiversity (because the area to be acquired is small). Nevertheless, loss of water surface (ponds, lagoons) may cause significant loss in aquaculture. The loss of about 41.53 ha of fish or shrimp ponds may cause a loss of about VND 2-4 billion /year (in 2009) or over VND 4.0 billion (in 2020), depending on location and environmental conditions.

175

485. It is found in the preliminary investigation that in the ROW of Ben Luc – Long Thanh expressway, some wells, schools, 110kV and 220kV lines, and electric poles will be relocated. Nevertheless, the relocation will not be very costly and in general, it will not cause major socio-economic impacts. To minimize disruption to community services due to relocation, the following measures shall be implemented:

(i) Water supply pipelines, power supply, communication lines and other utilities shall be re-provisioned before construction works commence

(ii) Provisions shall be made to preserve the operation of current facilities in sufficient quantity and in agreement with the local community.

(iii) Re-provisioning shall be undertaken in coordination with the utility company and affected households.

(iv) Affected households and establishments shall be notified well in advance of such disruption.

c. Regional Socio-Economic Impacts of the Project Location

i. Overall Impacts

486. One of the indirect impacts is land price increase as a result of the following:

(i) Ben Luc - Long Thanh expressway will push forward industrialization and urbanization of the Mekong Delta and the Southeast Regions. It will link the largest industrial parks and largest economic centers of the Southeast Region (Ho Chi Minh City, Dong Nai, Ba Ria – Vung Tau and Binh Duong) to Long An and other developing provinces in the Mekong Delta. As such, the project will promote the socio-economic development of communes and districts alongside the expressway.

(ii) Ben Luc - Long Thanh expressway will contribute to the improvement of other traffic modes in the Mekong Delta and the Southeast Regions because it will link big ports on the riversides of Thi Vai - Cai Mep, Sai Gon, Dong Nai, Nha Be, and Soai Rap with the ports in the Mekong Delta, and roads to international airports such as Tan Son Nhat and Long Thanh, thereby forming a multiplex traffic network. As a result, all socio-economic activities of provinces and districts alongside the expressway will be boosted.

487. Thanks to those positive impacts, a major part of households, many economic sectors and even the households whose land is acquired for the project will become accessible to more opportunities. This impact is positive and permanent.

ii. Structural Change in Population

488. The population structure will change as a result of changes in land use alongside the expressway. The trends include decrease in people living on agriculture and aquaculture and increase in people involving in services and industries. 489. Regarding promotion of industrialization and urbanization, at present, industries in Long An and other provinces in the Mekong Delta are under-developed with more than 80% population living on agriculture and aquaculture. The Ben Luc - Long Thanh expressway when in operation will speed up the industrialization and urbanization in this region. 490. Regarding improvement of women’s role, the project is not directly aimed at improving women’s social roles. Nevertheless, with the high speeds of economic growth, industrialization and urbanization, the opportunities for women in the districts and communes along the expressway to be involved in social activities will be improved. Those include better conditions for learning, cultural activities and employment.

176

491. Regarding promotion of job opportunities, the construction of Ben Luc - Long Thanh expressway will create temporary jobs for thousands of construction workers. A large number of young people residing in districts and communes along the expressway will have chances to take part in the construction. When the expressway is ready, the increasing industrialization and urbanization will create favorable condition for some of inhabitants to shift from the agriculture sector to industries or services, where income and education are better. 492. Based on the analyses above, it is concluded that positive and permanent impacts of the project are much greater than damages to a limited number of people who must relocate and lose land for the construction of the expressway and bridges.

d. Measures to Mitigate Negative Socio - Economic Impacts

493. To minimize all above anticipated negative impacts on the local community especially on the PAHs the following measures are applied.

i. Determination of the Most Appropriate Alignment

494. The distance of site clearance is about 73 m width over the total length of 58km of the expressway, a poor alignment planning will result in a great number of households, very large areas of agricultural, urban, and industrial land, ports, infrastructure facilities, cultural, religious, historic and cemeteries, etc. being affected, particularly in the districts of Ho Chi Minh City. 495. In order to mitigate socio-economic impacts, the consultants have selected 3 options for alignment, compared them and selected the optimal one.

(i) All three options I, II and III (Figure III.4, Chapter III) are the same for the sections from Ben Luc district in Long An province to Binh Chanh district in Ho Chi Minh City).

(ii) In this region the alignment has been selected so as not to encroach upon a big Cao Dai Temple at My Yen commune and a temple at Tan Buu commune in Ben Luc district

(iii) The alignment also avoids encroachment into industrial parks and establishment in districts of Ben Luc and Can Giuoc. From Km 14+400 to Km 15+650 in Binh Chanh district, the alignment has been adjusted to avoid the Da Phuoc Solid Waste Treatment Complex of Ho Chi Minh City.

(iv) From Nha Be district to Nhon Trach district in Dong Nai province: 3 options of alignments crossing over the big rivers Nha Be, Soai Rap and Long Tau have been studied (Figure III.4 in Chapter III): a) Option I (Southern Alignment): this alignment will cross over the Soai Rap river to Binh Khanh commune in Can Gio district, and then over the Long Tau river to Nhon Trach district. This option avoids Nha Be Fuel Complex, 2 high-voltage transmission lines (500kV and 220kV), Phu Huu port and many dense populated areas; b) Option II (Middle Alignment): this option may cross many residential areas, Phap Vo pagoda and various planned infrastructure facilities, causing many major negative socio-economic impacts. Therefore it is not supported by local authorities; c) Option III (Northern Alignment): this option avoids encroachment into some residential areas and Phap Vo pagoda, but this may affect many planned urban areas and ports, and particularly Nha Be Fuel Complex. This alignment may cause major negative socio-economic impacts, therefore, is not supported by local authorities.

496. Comparison of impact of the three options are shown in Tables V.20 and V.21.

Source: Tables V.20, V.21: from the “Resettlement Report” of the project ADB TA 7155 – VIE, October, 2009. 497. The data above show that Option I will has the least encroachment into residential land, agriculture land and houses. Therefore, Option I has been selected for feasibility study. A disadvantage of Option I is the proximity to Can Gio Protected Mangrove Forest (Can Gio Biosphere Reserve). However, it will cross Phuoc Khanh commune (for about 6km length) in the transition zone of Can Gio Biosphere Reserve and the alignment is located about 10 km from mangrove forests. 498. Option I of the project's alignment in the transition zone of Can Gio Biosphere Reserve is in accordance UNESCO regulations. Therefore, this option is accepted by the Management Board of Can Gio Protected Mangrove Forest based on its assessment that the project alignment "does not affect the growth of mangrove forest". 499. Option I not only limits encroachment into dense residential areas, industrial parks but also does not encroach into any historic and religious site (temple, pagoda, church, etc.). Therefore, selection of this option is the preferred major measure to minimize local negative socio-economic impacts .

ii. Proper Implementation of a Resettlement Action Plan

500. In order to minimize negative impacts of site clearance, the ADB TA 7155 - VIE has prepared a Resettlement Action Plan (RAP), complying with the Vietnam’ Laws and ADB’

178

Principles. This is suitable for districts and communes in the project site and feasible to restore production, income and living conditions of the PAPs. 501. The legal backgrounds for the site clearance and resettlement under the project include:

(i) The Constitution of the Socialist Republic of Vietnam (1992) (ii) The Land Law, promulgated under Order N 23/2003/L-CTN dated 10/12/2003

by the President. (iii) Decree 181/2004/ND-CP dated 29/10/2004 by the Government with

Guidelines on Implementation of the Land Law. (iv) Decree 188/2004/ND-CP dated 16/01/2004 by the Government on Method of

Land Pricing. (v) Decree 197/2004/ND-CP dated 02/12/2004 by the Government on

Compensation and Allowance for Withdrawn Land. (vi) Circular 116/2004/TT-BTC on Details of Compensation and Allowance. (vii) Decree 84/2007/ND-CP dated 25/5/2007 (viii) Policies of Ho Chi Minh City, provinces of Long An and Dong Nai on support

for site clearance and resettlement. (ix) New decrees, decisions of the Government; regulations and policies of

provinces to be issued in the site clearance and resettlement period of the project.

(x) ADB’ Safeguard Policy Statement (2009). 502. The project owner shall also build up resettlement sites for the households whose residential land is fully or mostly affected. All policies on site clearance and resettlement will be published and consulted with the PAPs before implementation. 503. Details of the policies and measures to apply to site clearance and resettlement under the Ben Luc - Long Thanh Expressway Project are given the Resettlement Report prepared by the Consultants for Project ADB TA 7155 – VIE (October 2009). Within the framework of this EIA Report, the policies and measures to mitigate socio-economic impacts cannot be assessed in detail. 504. Local authorities and independent consultants will monitor the site clearance and resettlement at every commune in order to ensure that those policies are properly implemented.

iii. Mitigation of Damages to Housing, Historic, Religious Sites and Technical Works

505. There are no historic or religious buildings likely to be affected, therefore, the project will not need any mitigation measure. Regarding relocation and removal of houses, public works and graves in the ROW of the expressway, the project owner will cooperate with the Resettlement Committees of districts to implement the policies and measures in compliance with the Laws and in conformity with actual conditions of PAHs. 506. Measures relating to house relocation are specified in the Resettlement Report of the Project ADB TA7155-VIE.

iv. Mitigation of Impacts on Ethnic Minorities

507. Specific measures for ethnic minorities (Khmer, Hoa - Chinese-origin people) are not necessary because the number of households of this category is very small and their socio-economic development is almost the same as that of majority (Kinh people).

e. Impacts of Explosive Materials

i. Impacts of Explosives Materials (UXO)

508. In the Vietnam War, thousands tons of bombs and mines were used in the districts to be crossed by Ben Luc – Long Thanh expressway. Almost all mines and bombs remaining after the war in residential areas and agricultural land were removed in the period of 1975 - 1985. Nevertheless, explosives remaining in deep layers should be a matter of concern for the safety of construction workers and the future expressway investigation and removal. Failure to locate and remove all unexploded ordnance (UXO) from the site would cause risks to public health. A specialized contractor from the military Civil Engineering Unit would be engaged to investigate and remove all such material from the site. 509. To minimize the impacts of UXO the project owner will collaborate with a Military Engineering Unit of the Ministry of Defense in investigation and removal of all UXO (bombs, mines) remained prior to construction. The region has been used for agriculture for more than 30 years and explosives material may remain in deeper layers though they cannot be found in top soil. Mine relocation and removal may last several months. This measure will certainly be taken to protect health of passengers, staff and technical men on and alongside the expressway.

4. Inclusion of Environmental Requirements in Bidding Documents

510. The Project owner (VEC) will cooperate with the International Consultant in preparation of bidding documents. The bid invitation document will not only specify requirements in technology, quality, schedules and expenditure of construction but also provide obligated requirements in mitigation of environmental impacts, particularly pollution control, risk prevention and protection of wetland ecosystem. The bid document shall include the EMP, particularly the environmental mitigation and monitoring requirements. 511. Requirements of financial provision for environmental protection, i.e budgets for treatment of solid waste, hazardous waste, wastewater, prevention of fire and explosion, sanitary work, water supply, prevention of land erosion, soil and water acidification, budgets for reforestation, environmental monitoring and environmental management capability improvement will be also specified in the bid invitation document. C. Environmental Impact in the Construction Stage and Mitigation Measures

512. The breakdown of the construction of Ben Luc – Long Thanh expressway in 3 provinces and city is as follows: 513. In Long An province, from km 0 to km 10 (crossing My Yen commune, Phuoc Ly, Long Thuong of Ben Luc and Can Giuoc districts): 4.8km of the expressway, an interchange with Trung Luong – Can Tho expressway (km0+700) (IC1), Ong Thoan bridge (km2+220,), toll gate. 514. In Ho Chi Minh City, from km2+200 to km30+500 (crossing communes of Binh Chanh, Tan Quy Tay, Hung Long, and Da Phuoc of Binh Chanh district; Nhon Duc, Long Thoi communes of Nha Be district and Binh Khanh commune of Can Gio district): 26 km of the expressway, interchanges with National Road 1A (km3+ 420, IC?), National Road 50 (km13 + 550, IC3), the Nguyen Van Tao in Nha Be (km21+850, IC4), Bridges over the Ong Keo and Ba Lao canals, big bridges of Binh Khanh (over the Soai Rap river) and Phuoc Khanh (over the Long Tau river), toll gates. 515. In Dong Nai province from km30+500 to km58 (crossing communes of Phuoc Khanh, Vinh Thanh, and Phuoc An of Nhon Trach district; Long Phuoc and Phuoc Thai communes of Long Thanh district): 28km of the expressway, interchanges IC5, IC6, IC7 and IC8, bridges of Thi Vai, Tac Doi, Bun Ngu, toll gates.

a. Impacts Caused Wastes and Mitigation Measures

i. Dust and Air Pollutants

516. Air pollutions in this phase will be generated by:

(i) Dust from digging and leveling, transport of dredged, construction materials etc. for the project

(ii) Emissions from construction machines containing dust, SO2, NOX, CO, THC, VOC, etc. due to activities of construction machines.

(iii) It is calculated that the digging and embanking volumes are estimated at 61,581m3 and 1,978,752m3, respectively. Therefore, the project will use a large number of vehicles and construction machines as listed in Table V.22.

Table V.22: Construction Machines Used in the Construction Phase

Machine Quantity (unit) Excavators 50 Road rollers 100 Bulldozers 50 Dredgers 50 Trucks 200 Concrete mixers 20 Compactors 200 Pile drilling machines 20 Cranes 40 Barges of various kinds 32 517. Emissions from motorized vehicles and road dust when they run on the access route to the project site will be the main causes of air pollution. It is difficult to predict the pollution load of road dust but in fact, road dust is precipitable and can not be widely dispersed. 518. Emissions from diesel heavy duty trucks contain pollutants such as dust, SO2, NO2, CO, VOC. It is calculated from the volume of materials to be transported that in peak periods, some sections or construction sites of the expressway may suffer 100 trips per 8 working hours (i.e. 5 minute/trip). The pollution loads of trucks and machines within 8 hour are predicted based on WHO’s Rapid Assessment Data (Table V.23) as follows: TSP = 0.06 kg; SO2 = 0.473 kg; NOX = 0.675 kg; CO = 10.5 kg; VOC = 1.05 kg. Thus, the volumes of those pollutants are minor when the large area of the site is taken into account.

181

the expressway will cause dust pollution along the sections under construction, and at construction materials storage sites. The dust content in the air (TSP and PM10) will increase there when trucks are in operation, particularly on dry days. 520. Main subjects of the impact will be residential areas alongside the expressway, and the transport routes used for project transport. The heaviest air pollution is expected at the communes of My Yen (Ben Luc district), Binh Chanh (Binh Chanh district), Da Phuoc (Binh Chanh district), Long Thoi (Nha Be district), Phuoc Thai (Long Thanh district), because these communes are densely populated and adjacent to the construction sites. 521. According to the monitoring data obtained in various construction sites (for instance, the construction of the East-West Expressway in Ho Chi Minh City), in the dry season and peak construction hours, within the distance of 50 m from construction sites, the dust content in the air is always higher than the permissible limit in the Vietnam National Technical Regulation for Ambient Air Quality (QCVN 05:2008/BTNMT). 522. Dust pollution due to transport will also occur on main routes such as National Road 1A, National Road 50, National Road 51 and other roads used for project transport. At present, air pollution as measured at 15 sites along the planned expressway is assessed as minor to medium (Chapter IV). The construction of the expressway will increase the air pollution, particularly at the junction to National Road 1A (in Binh Chanh district), National Road 50, the section to Nha Be district and the area closed to National Road 51 in Long Thanh district where the population density is high. 523. In case that mitigation measures are taken properly for the construction phase, the air pollution can be reduced significantly. This conclusion is made based on the monitoring results of the construction of the East-West Expressway in Ho Chi Minh City. The project for the East-West Expressway in Ho Chi Minh City is similar as that of Ben Luc – Long Thanh Expressway in term of construction volumes and distances to residential areas. Therefore, it is possible to apply the comparison method to predict air pollution in the construction of the Ben Luc - Long Thanh Expressway. This method is usually used in EIA. 524. Some data of air pollution monitoring implemented by ENVITECH for the East-West Expressway project in Ho Chi Minh City are shown in Table V.24.

525. This impact on air quality is inevitable at construction sites and may be assessed as major but local (the roadside only) and mitigable by technical and management measures. This impact is temporary and will be terminated when the construction phase of the project ends. 526. The construction will also need a large volume of concrete for construction of bridge and road structures. It is estimated that the project will need 10 concrete mixing stations and therefore, concrete mixing and transport for that purpose will significantly increase dust. According to monitoring results obtained by ENVITECH (2007 – 2008) in the East-West Expressway project, the dust content at concrete mixing zones is 0.35 to 1.20 mg/m3, depending on the monitoring time and operations of the mixers, and that is 1.16 to 4 times as high as the Vietnamese Standard for Ambient Air Quality (TCVN 5937 – 2005). As such, the impact of concrete mixing stations on the air quality can be assessed as medium but local and temporary, and mitigable by technical measures.

183

527. To minimize air pollution the following measures will be implement by the project owner and its contractors.

(i) Vehicles shall be checked in term of emissions with reference to the

Vietnamese Standard for emission of CO, hydrocarbon and smoke (TCVN 6438-2001). The Project Owner shall require subcontractor to show certificates issued by Vietnam Register or Traffic Police that trucks for the project meet the Standard of Vehicle Emissions.

(ii) Watering of exposed areas during rainless days: at each construction site contractors shall use 1 tanker truck (8 – 12 m3) for this purpose. Watering is the control measure to be taken at the zones of leveling, in the vicinity of materials stockpiles, and at the sections near populated areas, for instance the ones adjacent to National Road 1A and Provincial Road 50 in districts of Binh Chanh, Nha Be and Long Thanh, etc.

(iii) Based on experience from the East-West Highway Project, each section of 500 – 1000m needs 2 workers for watering 4 to 6 times per day, the frequency of which is seasonally dependent. A higher frequency is required in the dry season on the sections of high traffic density and large population. This measure shall be taken by contractors in the Ben Luc - Long Thanh Expressway Project for reduction of dust emission to the environment.

(iv) All vehicles carrying potentially dust - generating materials (sand, soil, stone, etc.) to, from and within the site shall be covered with suitable materials such as tarpaulins in order to prevent dust dispersion to the environment.

(v) Concrete mixers and asphalt stations are arranged at least 300 m distanced from residential areas. The distance ensures that the impacts of emissions, noise and offensive smells on residential areas are minor.

(vi) In addition to watering the zones in front of and inside concrete mixing stations, ditches of 4 x 10 x 0.3 m (L x W x D) would be made by contractors in order to wash vehicles before they go out of the stations. This measure is necessary for concrete mixing stations where the dust content is very high as it keeps down soil and sand adhering to vehicle wheels. These are highly feasible measures. The best measure is to wash truck body and tires before moving out of the construction to urban areas.

(vii) Enclosing walls (3.0 – 4.0 m in high) shall be built up around the construction sites that are near the sensitive receptors (schools, populated areas, churches, pagodas, etc). This measure is applied well at many infrastructure and road projects in Vietnam.

(viii) Dredged spoil shall be compacted to minimize dust dispersion to surrounding residential areas. The surface of dredged spoil storage sites maybe covered by dense plastic sheets to prevent dust dispersion. This is also good for soil erosion prevention in the rainy months. This measure is widely applied in other countries.

(ix) Workers handling construction materials shall be provided with personal work protection equipment (PPE / masks) to limit their exposure to dust.

(x) The project owner would arrange for monitoring noise and emissions from construction machines (bulldozers, trucks, etc.). Dust and air emissions are monitored via typical parameters such as total suspended particulates (TSP), PM10, SO2. In addition, the implementation of environmental protection measures by subcontractors at construction sites will be monitored so as to take necessary measures for air pollution control (environmental monitoring is described in Chapter VI).

ii. Domestic Solid Wastes

528. As estimated in Chapter III, in the peak periods of construction, there will be 1,000 workers at construction sites. The total amount of daily generated solid waste would be 800

184

kg. For each camp for 100 workers, the volume would be 80 kg/day. If not properly collected and treated, this volume can pollute soil, surface water, underground water and the air inside and near the worker camps. Particularly, in any period of epidemic, this kind solid waste can bring pathogens from workers’ camps to residential areas nearby. In normal conditions when camps are far from residential areas, this impact is predicted as minor, local and mitigable. 529. Impacts of domestic wastes from the worker camps can be mitigated by the following measures:

(i) Burning of domestic and construction wastes shall be prohibited. (ii) All solid wastes from workers’ camps are collected, segregated and

separately gathered in separate tanks of 100 – 240L each. Three types of solid wastes shall be segregated: organic wastes, oily solid wastes and hard solid wastes. Organic wastes (waste food, vegetables etc) could be put into a tank with blue label; hard non-water solid wastes (glass, wood) could be put into a tank with yellow label and hazardous wastes, including oily wastes could be put into a tank with red label. Waste foods can be given to local people for feeding animals. Hard solid wastes and hazardous waste shall be moved into a temporary storage site built at the worker camping area and collected weekly and transported to district's solid waste disposal site by a local environmental service enterprise. This model of solid waste management at construction worker camps could be properly applied in this project. The solid waste from construction sites in Binh Chanh and Nha Be, Ho Chi Minh City would be disposed at Da Phuoc Solid Waste Treatment Complex, which is about 0.5 to 25 km from the project site.

(iii) In cases when construction sites that last for more than 6 months (for building bridges), construction contractors can build pits for receiving and disposing of domestic solid wastes. The pit shall be located over 200m from boundary of the nearest residential area and over 10 m from eating area. A pit of 4.0m x 2.0m x 2.0m (L x W x D) with bottom lined with a clay-layer is adequate for a construction team of 50 workers in 6 months. When the team moves to a new construction site, trash pits shall be disinfected with lime or hypochlorite solution, then covered with a 20 – 30 cm layer of soil in order to avoid pollution.

iii. Construction Solid Wastes

530. The main solid wastes generated in the construction stage include biological wastes (cut trees, grass), waste concrete, cement, used fuel containers, unused excavated soil, oily waste cloths etc. 531. These types of solids may cause several environmental problems:

(i) Pollute canal and river due to disposal of construction wastes or storm water flowing across construction waste storage sites. Consequently, canals, rivers and groundwater would be polluted by turbidity, suspended solids, organic matter, oil and acidity (in case of run – off water from excess soil containing acidic materials).

(ii) Pollute land due to disposal of construction wastes. (iii) Pollute the air due to dust dispersion from construction waste storage sites. (iv) Affect on aesthetics of the area.

532. To minimize the impacts created by construction waste. The following measures shall be taken. 533. The main solid wastes during construction of roads and bridges include waste concrete, bricks, cements, scrap of iron and steel etc. Unused soil (dredged materials) is also considered construction solid waste.

185

(i) All construction waste are collected and stored properly at planned spoil

disposal sites for reuse. Spoil disposal sites shall be located closely to each construction site, but far (over 200m) from residential, commercial or cultural sites.

(ii) Disposal of construction wastes to river, canal or field is forbidden. (iii) Contractors would employ 1-2 sanitary workers for collecting and segregating

sanitary waste, hazardous waste and construction waste at each construction site. Contractors shall sign contract with environmental service enterprises of districts for safe disposal of construction wastes that are not reused for site leveling.

(iv) Scrap iron and other kinds of metallic waste are collected and sold to recycling entities.

(v) Contractors keep at a proper place the volume of dredged spoil (with high contents of organic matters) that is not used for leveling, and allow local people or companies to take it away for soil reclamation or forestation (farmers in the project districts like to use this type of soil for field reclamation of filling low land area).

iv. Domestic wastewater

534. The construction of the expressway will need a large number of workers. On average, each section of 5 - 6 km needs a camp for 100 workers. The number of workers at construction sites would be up to 1,000 (peak periods). As such, the maximum volume of sanitary wastewater would be 120 m3/day with main pollutants of suspended solid (SS), organic matters, oil and grease, nutrients (salts of nitrogen and phosphorus) and microorganisms. 535. The pollution loads of workers’ sanitary wastewater are predicted as shown in Table V.25. Table V.25: Estimated Pollution Loads of Domestic Wastewater from Construction

536. In case of without treatment, the concentrations of main pollutants such as BOD, COD, SS in workers’ wastewater are: BOD: 416 mg/L COD: 784 mg/L SS: 890 mg/L 537. Those concentrations of pollutants exceed the allowable limits of the Vietnam National Regulation for Domestic Effluent (QCVN 14:2008/BTNMT, column B, where the permissible BOD, SS are 50, 100 and 100 mg/L, respectively). Furthermore, domestic wastewater from workers’ camps may encourage epidemic diseases if any (cholera,

186

diarrhea, etc.) occur. The subjects of this impact include residential areas near the camps and watercourses nearby. 538. Since the number of workers in each camp is at most 100, the impact of domestic wastewater generated from each camp to the surrounding environment is assessed as local and mitigable. 539. To properly mitigate the potential impacts caused by domestic waste water the following measures are suggested.

(i) In order to control pollution due to sanitary waste, contractors shall install treatment facilities (mobile toilets) at appropriate places in the construction sites and particularly at workers’ camping area. Each camp of 100 workers will need at least 4 mobile toilets.

(ii) As for construction sites located far (over 500m) from residential areas, it is permitted to build temporary bench latrines with a enclosure around a pit. The enclosure may be made of Nipa palm, composite or bricks. Lime is used for daily disinfection and a thin layer of soil is added every 2 to 3 days. Bench latrines shall be located at least 100 m from residential area and/or camps. When workers move to new construction sites, latrines should be sealed off and disinfected with lime. The simple and cheap bench latrines are a preferred solution for construction sites far from residential areas in rural areas. This type of toilets is suitable for the terrain of districts in the project site, particularly in Ben Luc, Nhon Trach and Long Thanh.

(iii) At construction sites near residential areas, contractors should build up septic tanks toilets. Many types of septic tanks can be utilized for actual conditions. Figure V.7 illustrates an appropriate model for construction sites near residential areas. The model has high treatment effectiveness, for instance, 80% of BOD and 90% of microorganisms may be removed. The liquid components from septic tanks should be collected and transferred to the local sewage system. In addition, contractors should install hand-wash taps at each sanitary site for users.

Figure V.7: A Model of 3- Compartment Septic Tank

v. Wastes from Machinery Washing and Maintenance

540. Storm water flowing over construction sites, fuel storage sites, machine washing and maintenance sites sweeps away waste on the ground such as sand, soil, high alkalinity created by excessive cement, oil and grease, refuse, etc. This kind of wastewater usually has high turbidity, SS and maybe various hazardous wastes such as oil and grease, etc. and it can therefore pollute the land, surface and ground water environment. 541. Wastewater from construction sites, fuel store sites and from machinery washing will be discharged to fields, rivers or canals along the expressway. At present, water pollution of those rivers and canals is minor and medium with only some parameters exceeding the Vietnamese National Technical Regulation for Surface Water Standard (QCVN 08:

187

2008/BTNMT) (Chapter III). Water pollution, particularly in small canals, will increase when receiving wastewater from construction sites. Nevertheless, since the volume of this kind of wastewater is limited, this impact is assessed as minor, temporary and mitigable. 542. To minimize this impact, this wastewater shall be treated by settling tanks and oil skimmers (oil/water separators) prior to discharge to surrounding fields or canals. A diagram illustrating the treatment of waste water from washing construction machines and vehicles is given below (Figure V.8). A system as such is simple and popular and the design and operation of its devices are so simple that it is not necessary to specify here.

vi. Soil, Surface and Ground Water Pollution by Wastes

543. Site studies show that the ground water levels in districts of Ben Luc, Binh Chanh, Nha Be, and Long Thanh are deep (15 – 35 m at the time of study). In districts of Can Gio and Nhon Trach, people rarely use ground water because it is saline. 544. In the construction phase, soil, surface and groundwater pollution may occur with main reasons as follows:

(i) Leakage of oil and/or fuel from construction machinery; (ii) Rash disposal of solid waste and sanitary wastewater from construction

workers’ camps; (iii) Effluent from construction activities; (iv) Storm water flowing over construction sites. (v) Domestic and construction wastes mentioned above.

545. Volumes of storm water may be very high during rainy days. Storm water can lead to soil erosion and inundation. Additionally, storm water at road construction sites in this project may contain high turbidity, SS, acidic materials (at acid sulphate soil areas), metals (Al, Fe, Zn) and oil. Therefore, storm water may pollute land, surface and groundwater, where it will flow across. Consequently, water quality would be degraded, affecting aquatic organisms and water supply. 546. Although the volume of water to be used in the construction of the expressway will be large, approximately 1,200 m3/day on average and maybe up to 3,000 m3/day in peak periods, a major part of water will be consumed for construction (for instance, concrete mixing, dust control spraying, etc.) therefore, the volume of generated wastewater would be limited. It is expected that the impact of wastes in the construction phase on soil and underground water is assessed as minor and possible to mitigable. 547. To minimize impacts of wastes to the land and groundwater environment the following measures shall be implemented

(i) Proper management of fuel storage site: each construction site shall install a special site for storage of fuel containers. This storage site shall have roof,

Wash water from vehicles,

machines

Settling tank

walls and cement ground base. A kerb surrounding the storage site for prevention of fuel leakage is required.

(ii) Proper treatment of all types of solid wastes and wastewater by the technical measures given in relevant section.

(iii) Discharge and/or disposal of untreated hazardous wastes to the land is forbidden.

(iv) Install ditches to prevent flow of storm water to cultivation, aquaculture areas or water intake sites for domestic use.

(v) Properly treat acidic water. (vi) Where significant oil and grease is expected use of oil/water separators for

treatment. (vii) Regular implementation of the monitoring program for land and groundwater.

b. Impacts of Non-Waste Sources and Mitigation Measure

i. Noise Pollution

548. According to results of measurement at the sites alongside the expressway (Chapter III), at present the baseline noise there is still lower than the permissible limits of the Vietnam Standard for Noise at mixed residential and commercial - production areas (TCVN 5949 – 1998), excepted for the sites at National Road 1A and National Road 51. Noise pollution at construction sites and the vicinity is predicted to be increased as a result of the construction activities. 549. The main sources of noise will be construction machines with the noise levels as high as 70 – 96 dBA, which however significantly decrease over distances. 550. The model of noise transfer prediction indicates that noise reduction is a logarithmic function of the distance from the noise source. Based on the model, it is computed and found that noise reduces by 6 dB(A) when the distance from the noise source doubles. Results of computation based on the noise transfer model applicable to construction machines and trucks in operation are shown in Table V.26. 551. Noise of almost all construction machines except for hammer drill / pilling machine is not higher than 75dB(A) at 150 m distance. Piling machines are the strongest noise generation source with the impacting distance of 383 m. As such, noise pollution will cover a large zone beyond the construction sites of the expressway and bridges. It is noteworthy that the noise increase by many machines working in unison is minor. 552. The results above are obtained given the topography is flat without obstruction. When the site has a vegetation carpet, noise can be further decreased over distances.

Table V.26: Noise Transfer Over Distance

553. Thus, the noise impact on roadside residential areas can be assessed as major (significant) with a large affected zone (i.e. where noise is higher than the permissible limit in the Vietnamese Standard for Noise at Public Areas, TCVN 5949-1998) and difficult to mitigate. 554. It is possible to use the noise monitoring results obtained by ENVITECH (March 2008) (Table V.27) at 10 mobile sites in the construction of the East-West Expressway project in Ho Chi Minh City to prove the noise increase at construction sites of the Ben Luc - Long Thanh Expressway.

Source: ENVITECH, March 2008 555. Data in Table V.27 shows that the construction of the expressway significantly increases noise when compared with the time before construction (March 2008 vs. July 2005).

190

556. Loud noise can damage health, cause inconvenience to people near the construction sites and affect sensitive animals. Data of the relations between noise and health are given in WHO’ documents and various medical literatures. 557. Considering the information mentioned above, it is possible to state that residential areas far from the construction of the expressway and bridges (at least 150 m) will suffer minor impacts. In contrast, populated areas near National Road 1A (the communes in Ben Luc and Binh Chanh districts), National Road 50 (the communes in Binh Chanh district), and particularly residential areas of Nha Be district, and Phuoc Thai commune adjacent to the expressway would be exposed to heavy noise. It is noteworthy that the sensitive receptors as cultural and religious buildings, hospitals and the like that are located about 300m from a very strong noise source (eg. pile drivers) may still be affected. Therefore, noise reduction measures are required for those receptors. 558. In order to reduce noise pollution, the project owner shall require and check construction contractors take the measures as follows.

ii. General Measures

(i) Arrangement of sources of loud noise such as concrete mixers, piling machines, electric generators, etc. at least 300 m from sensitive subjects (for instance, residential areas, hospitals, schools, churches, pagodas, offices, etc.);

(ii) Restriction of operation of pile drivers, pneumatic wrenches and operation of other strong noise generation sources in nighttime (22:00 to 6:00);

(iii) Regular maintenance and checkup of vehicles such that they are always in good conditions and satisfactory to the Vietnam Noise Standard;

(iv) Stipulation of maximum speed of trucks in construction sites; (v) Providing workers near sources of loud noise with noise protection devices

such as ear-plugs.

iii. Mitigation of Noise for Sensitive Subjects

(i) In case that it is impossible to ensure the minimum distance for sensitive receptors as mentioned above, contractors shall take special noise reduction measures, one of which is to build up noise barriers around sources of heavy noise. The walls of 3.0 – 4.0 m high, may be made of bricks, thick wood or other materials. Depending on material of construction, the barriers can reduce noise levels by 10 - 15 dB(A). Noise Barriers shall be as close to the noise source as possible. A standard design of noise barrier is not practical in this FS study stage. However, based on the capacities of noise transmission reduction of materials given below and local actual conditions (distance from the construction site to nearest sensitive noise receptors, topographic features, availability of materials...) contractors will design and construct noise barriers to minimize noise pollution to acceptable levels.

(ii) In addition, landform is also effective in noise reduction. The landforms that

can be utilized as acoustic screens are earth banks, and enclosing walls of public works

559. In addition to technical measures, managerial ones are feasible. For instance, operations of heavy-duty trucks shall be managed, particularly when they work near sensitive zones.

iv. Vibration Impact and Mitigation

560. Among vibration sources, piling machines are highest. Piling machines in operation can cause large vibrations with examples as follows:

191

(i) Binding sheet piles, 4.5 – 5m long and U-shape are driven in to the necessary depth. An 8-ton hammer with the pulse of 48 KJ can cause vibration of 12.9 mm/s at 10 m distance.

(ii) Staking a pile into muddy ground with the pulse of 30 KJ can cause vibration of 4.3 mm/s at 10m distance.

(iii) A diesel hammer working on clay ground can cause vibration of 7 mm/s at 10 m distance.

561. In order to protect offices and public works (schools, hospitals, etc.) the maximum vibration shall be < 2 mm/s. As such, the safety distance for vibration is 7 m for wooden works on clay ground and 12 to 16 m for construction works on weak foundations. 562. Vibration monitoring results obtained by ENVITECH in the construction of the East-West Expressway, show vibration caused by the construction of the expressway (Table V.28).

Vietnam Standard for Vibration in construction activities (TCVN 6962-2001)

0.055 (=75dB)

Source: ENVITECH, March, 2008 563. Based on the monitoring data in Table V.28 it is possible to anticipate that vibration of construction machines and trucks in the construction of the Ben Luc - Long Thanh expressway would be lower than the allowable limit. Besides, a limited number of machines of strong vibration will work for a relatively short period. For instance, piling machines will work for at most 3 to 4 months at a section; electric generators will work as stand-by in case of electricity cut off (rarely occurs). Therefore, the impact of vibration on people and construction works in the vicinity of construction sites is assessed as minor and temporary.

192

564. To minimize vibration pollution the following measures will be applied.

(i) Offices and similar sensitive receptors (schools, hospitals, houses, etc.) are safe when the maximum vibration < 2 mm/s. For protection of construction structures, the safe distance from a source of medium vibration (for instance, a heavy trucks, generators, etc.) is 7 m for wooden structures on clay and 12 to 16 m for structures on muddy soil. The minimum distance is 30 – 40 m for piling machine into clay ground and 45 m for muddy ground.

(ii) Results of vibration monitoring by VESDEC in various infrastructure and traffic development projects (for instance, vibration from the construction of the International Terminal of Tan Son Nhat Airport in Ho Chi Minh City and vibration from vehicles in national roads) show that the levels are lower than the allowable limits. Therefore, it is not necessary to take any measure to reduce vibration from operations of vehicles in the construction of the expressway and bridges.

(iii) Noise and vibration from operations of construction machines in the construction of the expressway and bridges shall be monitored.

v. Impact of Acid Sulphate Soils and Mitigation Measures

565. Ben Luc – Long Thanh expressway will cross some low land areas such as communes of districts of Ben Luc, Binh Chanh, Nha Be and Can Gio. At those sites road foundations must be embanked against water inundation in the flood season. According to the preliminary design of the expressway, the foundation must be at least 0.5 m higher than the highest flood level recorded in the last 100 years to secure continuous traffic on the expressway. 566. Noticeably, the expressway will be constructed at some areas of potential and actual acid sulphate soil – ASS (see the soil map in Figure IV.1, Chapter IV). The investigation of the Sub – National Institute of Agriculture Planning and Projection found that the foundation is shallow potential acid sulphate soil (PASS) which occurs at communes of Quy Duc and Da Phuoc in Binh Chanh district, and actual acid sulphate soil (AASS) and deep potential acid sulphate soil occurs at Binh Khanh commune of Can Gio. Digging and embanking in acid sulphate soil may cause acidification of soil and water. This matter is actually occurring in many areas in the Mekong Delta and Western part of Ho Chi Minh City. 567. The mechanism of the acidification is as follows:

(i) Acid sulphate soil contains high contents of pyrite (FeS2), which, when the soil is dug or turned upside down, is exposed to sunlight and contacted with water, thereby oxidized with the presence of microorganisms.

(ii) At high pH, pyrite can be oxidized when ferrous ions (Fe2+) are present: (iii) The latter is slow when pH<4 but very speedy (more than million times higher)

with the presence of catalytic microorganisms (iron-oxidation bacteria). 568. The study of NEDECO for the WB Project for “Inland Waterway Rehabilitation in the Mekong Delta (1999)” indicates that 1m3 of actual acid sulphate soil can release 20-60 moles of acids. That is the basis for calculation of acidification when acid sulphate soils are dug and embanked. 569. Figure V.9 shows the released acidic material from dredged AASS may pollute the surrounded water environment. If acidic water has high acidity (pH < 5), high concentrations of Fe and Al, it may damage cultivated plants and fish species.

193

Figure V.9: Acidic Water Resulted from Digging Acid Sulphate Soil (Photo in Long

An province, where serious AASS occurs)

570. Storm water flowing over disturbed acid sulphate soil is easily acidified and then water flows to watercourses, acidifies canals and aquaculture ponds. This phenomenon may occur at districts of Can Giuoc, Binh Chanh and Nha Be. Certain results of acidification include damages to aquatic resources and water quality of rivers and water there. According to the studies of Le Trinh et al., the section in Cu Chi district of the Sai Gon river (Ho Chi Minh City) has been acidified evidently (pH = 4.5 – 5.5, whilst the pH of the Dong Nai river, which is not affected by acidic water is usually neutral, i.e. 6.8-7.3). This is a proof of the impact of digging/embanking in acid sulphate solids in Long An and Ho Chi Minh City. 571. Fish species may be killed when pH of water is too low. The effects of water acidity on fish species were evaluated by Wellburn (1988) as given in Table V.29.

194

Table V.29: Short-Term Effect of Water Acidity on Fish Species

6.5-9.0 No effect

6.0-6.4 Unlikely to be harmful/except when C02 level are very high (> 1000 mg/L)

5.0-5.9 Not especially harmful except when C02 levels are high (>20 mg/L or ferric irons are present

4.5-4.9 Harmful to the eggs of salmon and trout species and to adult fish when Ca2+, Na+ and Cl- are low

4.0-4.4 Harmful to various fish species

3.5-3.9 Lethal to salmonids

3.0-3.4 Most fish are killed within hours Source: Wellburn ( 1998) 572. Nevertheless, according to the design of the project, embanked soil will be strongly compacted then covered with layers of sand and macadam and the oxidation will be hindered and furthermore, the leachate of acidified water (if any) from the road foundation to rice fields or aquaculture ponds would be minor. Therefore, it is predicted that if the design is observed, the impact of the construction of the Ben Luc – Long Thanh expressway would be minor. In contrast, digging and storage of spoil not satisfactory to technical requirement may cause serious acidification of aquaculture ponds and rice fields. Sections 1 and 2 (Ben Luc, Can Giuoc, and districts in Ho Chi Minh City) may be affected by this impact at minor to medium levels. 573. The embankment of the road foundation may also cause other negative impacts such as flow obstruction, water inundation landscape change, air and noise pollution due to construction machines. Those impacts are already anticipated and assessed in other sections. 574. The following measures are recommended in order to prevent the acidification during road construction at acid sulphate soil areas.

(i) The physical - chemical structure of soil shall be analyzed before digging to indicate which layer and what depth to be dug;

(ii) In case that a large volume of acid sulphate soil must be dug for embanking the road bed, the contractor shall cover the face of the road bed with a layer of soil or clay not containing acid sulphate soil.

(iii) Storm water from construction site with high acidity (pH < 5.0) shall be treated with lime with the amount calculated based on the volume and pH of water. This measure is costly and therefore, it will be applied at special places, for instance, water intake for domestic use, zones near agriculture ponds or cultivating fields and in case that this acidic water is generated by project activities (in some places without project activity pH values of pond, canals are may be lower than 5 or lower than pH value of storm water from construction site. In this case, project will not be responsible for water treatment). This measure has been taken effectively at some construction works in the Mekong Delta. Photos illustrating the leachate from an acid sulphate soil layer and the use of lime for treatment of sulphate water at construction sites in the Mekong delta are given in Figure V.9 and V.10, respectively.

(iv) In case that spoil is heaped up along the road, in order to avoid of the transfer of sulphate water to agriculture and aquaculture land, construction contractors shall design and utilize storing grounds with enclosure of suitable width and height. The capacity of a storing ground is determined case by case. The

195

enclosure shall be 1.0 – 2.0m wide, 1.0 – 1.5m high and carefully compacted against erosion and percolation.

Figure V.10: Treatment of High Acid Sulphate Soil and Acidic Water with Lime

(v) The enclosure shall preferably include resettling reservoirs to reduce turbidity and suspended solid and to treat leachate of acidic water (including neutralization with lime if pH of water in the reservoir is lower than that at the surrounding environment). A design of a reservoir with settling tanks for storing dredge spoil is shown in Figure V.11.

Figure V.11: Model of a Reservoir with Settling and Neutralizing Tanks to Prevent Impacts of Acidic Water)

(vi) The aforementioned model of acidic dredged water treatment for spoil grounds have applied effectively to various projects in the Mekong Delta (for instance, the WB project for “Rehabilitation of Inland Waterways of the Mekong Delta”, 2000 – 2005 designed by SMEC, monitoring by VESDEC of VESDI).

Spoil ground

196

(vii) Any construction contractor who causes soil or water acidification that kills fish or shrimp or damages crops shall be subject to compensation and fines under Vietnam laws.

vi. Impacts of Foundation Elevation and Mitigation Measures

575. The topography of the entire project expressway is generally low and flat (except for the section that crosses over the Center of Nhon Trach district). The flow in the flood season is NW - SE (in Ben Luc, Binh Chanh, and Nha Be) or N-S (Can Gio, Nhon Trach and Long Thanh). The main meteo-hydrological feature of the project site is bi-seasonality. At the end of the rainy season (October to December), flood water from the Plain of Reeds (Dong Thap Muoi) is poured to the East of Vam Co and West Vam Co rivers and other rivers and canals in the basin of the Vam Co river covering Ben Luc and Can Giuoc districts. Meanwhile, flood water from the upstream rivers such as Dong Nai and Sai Gon flows to the rivers of Nha Be, Soai Rap and other canals. During that period, a major part of low land in Ben Luc, Binh Chanh, Nha Be, Can Gio, and Nhon Trach are inundated, and canals play the role of water drainage for residential and urban areas and industrial zones in the project site. 576. As such, if a road foundation is built up with an elevation of over 3m above the existing ground, a dike obstructing flood water is formed. It means that in the rainy/flood season, water flow is stopped by the expressway and the Northern zones are then inundated. This phenomenon has been recorded at some national roads in Central Vietnam and the Mekong Delta. Inundation, if occurred, will cause a series of adverse environmental and social effects, which include water pollution, epidemic disease transmission, crops and aquaculture damages, construction work degradation and life disturbance. This impact is assessed in two cases: if drainage culverts under the road are not effective, the impact is medium to major, depending on locations. Nevertheless, according to the design, the expressway will have effective cross drainage which will be regularly maintained and cleared of debris. Thus, if contractors follow the design, this impact is predicted as minor. 577. In order to mitigate this impact, the project owner shall implement the following measures:

(i) Carefully study the topographic features of each section of the expressway to ensure correct design of road foundation.

(ii) Design and construct adequate culverts dependent on location and sized to allow rapid water drainage from the upstream to downstream area in the event of intense rainfall.

(iii) Strictly control the construction, operation, maintenance and clearing of drainage culverts and ditches during expressway construction and operation.

vii. Impacts of Landslide and Soil Erosion

578. Results of the investigation and evaluation of characteristics of geology, landform, hydrology and engineering geology throughout the alignment from Ben Luc district to Long Thanh district indicate the causes of landslide as follows:

(i) Slope angle is the main cause of landslide. The higher slope angle, then the lower the stability of the slope. The slope of the entire alignment is not high, at most 0 – 0.5% and the average elevation is 0.5 – 1.5m, of landslide by topographic difference is minor.

(ii) Groundwater in soil layers has close relations with the surface flow. Heavy rains or flood water form an underground flow that hollows the top soil base and when water has gone down, an underground water depth difference is created, damaging the loosened top soil. When it is drought, lower hollows shrink and consequently, soil cracking and depression are easy to occur.

197

(iii) Underground depths of aquifers in Ho Chi Minh City, Long An, Dong Nai are decreasing. According to Nguyen The Ngoc (2000), the underground depth in Ho Chi Minh City has annually decreased 1.5 m to 2 m. Aquifers are deteriorating because the extraction of groundwater in the City is more than 600,000 m3/day while the supply capacity is less than 200,000 m3/day. Monitoring data provided by the Southern Union of Engineering Geology and Hydrology shows the different decreases of underground depths at some locations. In Binh Chanh and Nha Be where the expressway will cross, the annual decrease is approximately 0.5 m to 0.77 m.

(iv) In association with the underground depth decrease, salinity intrusion and land depression are increased. Decreased depths of extracted aquifers and the increasing growth of construction works on the ground have jointly deformed the landform (i.e. depression) at many zones in Ho Chi Minh City.

(v) The sloping terrain in the West to East direction is another factor. With the elevation of 0.5 – 1m on average, surface flows are easy to form after heavy rains. The flow will affect the road face and cause erosion when the rainfall is large enough. Therefore, the zones where the slope is in the North to South direction, i.e. crossing over the centerline of the expressway (for instance, Ben Luc and Nhon Trach) will have high risks of erosion.

579. Erosion of the positive embankment slope can fill up the road face and that of the negative embankment slope can lead to erosion of road shoulders. Both cases lead to traffic obstruction and dangers to people on the expressway. 580. Based on site studies and technical data, it is predictable that geological landslide in the rainy season is likely to occur at the sections and zones as follows: a) section from the start of the expressway (My Yen commune in Ben Luc district) to Hung Long commune in Binh Chanh district (around National Road 1A) overlies the ground of non-strengthened alluvia with a motley layer. Depression is easy to occur if the road foundation is not reinforced; b) sections crossing Quy Duc and Da Phuoc commune, Binh Chanh district, Nhon Duc and Long Thoi commune in Nha Be district, Binh Khanh commune in Can Gio district, Phuoc Khanh in Nhon Trach district overlie weak (soft) foundations, therefore, and depression is easy to occur. 581. Topographical landslide can occur according to the height of the expressway embankment above the surrounding land. The section from Ben Luc to Nha Be crosses flat terrain while the section from Nhon Trach to Long Thanh is slightly higher elevation. Details of the land fill elevations necessary for building up the expressway are given in Table V.30.

Table V.30: Average Elevations of Land Fill

Section Top soil Filling thickness (m) Km0 – Km12 On weak foundation, 3m-4m 1.5 – 2.5 Km12 – km16 On weak foundation, 4m-10m 2.0 – 2.5 Km16 – km31 On weak foundation, 14m-25m 8.0 - 10.0 Km31 – km36 On weak foundation, 3m – 8m 2.0 – 2.5 Km36 – km42 On strong foundation 1.5 – 2.5 Km42 – km52 On weak foundation, 4m – 10m 1.0 – 1.5 Km52 – km58 On weak foundation, 3m – 15m 6

(i) Km 0 – km 12, i.e. the section from the start of the expressway to Ong Keo canal that crosses My Yen, Binh Chanh, Tan Quy Tay and Hung Long communes: the land fill elevation is 1.5 – 2.5m. The landslide risk of this section is high because the land fill elevation is high.

(ii) Km 13 – km 16, i.e. the section from Ong Keo canal to Ba Lao canal, crossing Da Phuoc commune: the land fill elevation is 2 to 2.5m, i.e. the largest over the entire expressway and therefore, the risk is very high.

198

(iii) Km 17, i.e. Ba Lao bridge: this is affected by the flow of Ba Lao canal and the risk of landslide is also high.

(iv) Km 17 – km 23 from Ba Lao canal to the Soai Rap River: the terrain is flat and landslide can hardly occur, unless there is a heavy rain.

(v) Km 24 – km 30, i.e. the section crossing Binh Khanh commune in Can Gio district: the risk of erosion is very high because the geological foundation is very soft while the zone is adjacent to big rivers such as Soai Rap and Long Tau. According to the selected plan of alignment, the section from km 24 to km 26 will go along the bank of the Soai Rap river. That is the section of extremely high risk of landslide. Therefore, it shall be taken into account during the design and construction of the bridge.

(vi) Km 31 – km 36: this section crosses Phuoc Khanh commune in Nhon Trach district, where the topographical difference is 2 – 2.5m. Therefore, the risk of landslide is high.

(vii) Km 36 – km 42: this is located within Vinh Thanh commune in Nhon Trach district where the geological foundation is strong and the topographical difference is 1.5 – 2m. As such, landslide can hardly occur.

(viii) Km 42 – km 52: crossing Phuoc An commune, Nhon Trach district, where the land fill elevation is so low (1 – 1.5m) that there is less risk of landslide.

(ix) Km 52 – km58 (end of the expressway): crossing the Thi Vai, a big river in a zone of weak foundation. The risk of landslide is therefore high and shall be taken into account during the design and construction of the bridge.

582. The information mentioned above show that the problems of erosion and landslide should be greatly considered in the design and construction of the expressway as well as its bridges. The impact of erosion and landslide can be predicted as minor to medium (depending on sections) but mitigable technical solutions. 583. In order to limit erosion and landslide of river banks and road beds, particularly at the construction sites of bridges on weak soil with high flow rates such as Ba Lao bridge (Km10+100), Binh Khanh bridge (Km23+400), Phuoc Khanh bridge (Km30+300) and Thi Vai bridge (Km53+100), the following measures shall be taken.

(i) An appropriate number of culverts with suitable dimensions are designed and built up at the zones which are vulnerable in the flood season (particularly the sections crossing Ben Luc, Binh Chanh and Nha Be) to avoid flood water infiltrating the road beds under construction. This measure will also help prevent upstream water inundation in the rainy/flood season.

(ii) Drains are arranged properly so as to avoid the erosive effect of flows. (iii) Roadside draining ditches are paved with stone or concrete when roads are

under construction. (iv) The uncovered areas of talus are reduced by ramming and grassing when

road beds are under construction. (v) Do not cut off vegetation carpet along the river bank and along the

expressway. Vegetation carpet is effective in preventing soil erosion and landslide.

(vi) Planting mangrove trees along the river bank where close to the road and/or bridges, particularly at the bridge construction sites. The most appropriate trees for planting are Nipa palm (at the brackish and light saline areas) and Rhizophoa spp (at the light saline areas).

viii. Impacts Caused by Other Construction Activities

584. During the construction stage the following activities will be implemented by contractors.

(i) Operation of borrow sites for taking soils for road construction.

199

(ii) Construction and use of access roads for material transport (iii) Land excavation and dredging during road and bridge construction.

585. In this project, quarry operation is not expected as all amounts of stone, sand and gravels will be provided to construction contractors by material providers who operate private quarries. 586. At this stage of the study, specific locations of access roads, borrow sites and dredged material disposal sites are not determined, so detailed impact assessment and mitigation measures may not be anticipated. However, the general potential impacts of above mentioned activities are expected as follow.

(i) Encroachment into forest, agricultural, commercial and / or residential areas, causing ecological and socio-economic impacts (in cases of construction and operation of access roads, spoil storage sites and borrow pits). Socio - economic impacts of land acquisition for borrow sites, access roads or spoil disposal sites are assessed in Section V.B.3. Impacts on the biological environment are assessed in Section V. B. 2 (Chapter V).

(ii) Noise, vibration, air, water and land pollution caused by operation of earthwork at borrow sites, access roads and excavation/dredging activities. Environmental pollution generated by operation of access roads, borrow sites and excavation/dredging activities are assessed in above Section V.C.1. (Chapter V).

(iii) Land slide and soil erosion caused by construction and operation of access roads, borrow sites and excavation /dredging, spoil disposal activities. This type of impacts is assessed in Section V.C.1. (Chapter V).

587. Beside the above expected impacts operation borrow sites may cause the following specific adverse impacts:

(i) Land and water acidification caused by storm water, flowing across borrow sites at acid sulphate soil areas.

(ii) Lost of vegetation. (iii) Disfigurement of local landscape (iv) Creation of habitats for growth of mosquitoes and pests. (v) Safety risks due to creation of stagnant bodies of water and flooded pits.

588. All above expected impacts caused by operation of borrow sites are assessed as minor, short-term and mitigable. 589. To avoid the impacts associated with access road construction and operation the following measures will be applied.

(i) Proper implementation of resettlement action plan (RAP) in case of land acquisition for access road construction.

(ii) Proper control of soil erosion, land slide, storm water, construction and domestic wastes during access road construction.

(iii) Proper noise, vibration control and dust control during truck movement at residential and/or commercial areas.

590. To minimize impacts caused by operation of spoil disposal sites the following measures are suggested.

(i) Dredged and excavated materials shall be reused or provide for local residents for land reclamation as soon as possible. The remaining spoils can be disposed into low elevation sites for road construction or land reclamation.

200

(ii) Temporary vegetation of stockpiles would be carried out to minimize soil erosion, landslide and dust pollution.

(iii) Temporary sediment traps (ditches and ponds) would be installed if high sediment laden runoff were observed.

591. To avoid impacts associated with borrow pits dredge and operation the following measures will be implemented.

(i) Select proper places for setting up borrow pits to avoid areas of serious acid sulphate and saline soils and to avoid encroachment into forest, cultivation, commercial and residential areas. Borrow sites shall be located over 300m away from residential commercial, cultural sites.

(ii) Proper soil erosion control during borrow pits construction and operation by proper design and installation of adequate drainage system.

(iii) Proper control of storm water at borrow sites in the rainy season by using sediment traps, treatment of turbidity, strong acidic water (by lime) and oil separation water if high turbidity, high acidity or high oil content were found.

(iv) Proper dust control during dredging, excavation at borrow sites and earth transport.

(v) Topsoil (about 15 cm) will be kept and refilled after excavation is over, (vi) Long – term material stockpiles will be covered to prevent wind erosion, (vii) Upon completion of extraction activities, re-contour borrow/quarry pit wall, or

fill-up when there are available and suitable materials such as excavation spoils, replace topsoil, and re-vegetate with native species such as grasses and fast-growing shrubs,

(viii) Quarries and borrow pits will not be established in national, provincial, district and village conservation forests and other protected sites,

(ix) Operation of existing quarry/borrow sites shall be preferred over establishment of new sites, as much as possible,

(x) In case the Project will involve new quarry/borrow sites, necessary approvals from environmental authorities shall be obtained prior to operation of such sites,

(xi) During borrow site operation, provide adequate drainage to avoid ponding or accumulation of stagnant water,

(xii) Borrow/quarry sites shall not be located in productive agricultural land and forested areas,

(xiii) Upon completion of extraction activities, borrow pits shall be dewatered and fences shall be installed, as appropriate, to minimize health and safety risks,

(xiv) To avoid drowning when pits become water-filled, measures such as fencing, providing flotation devices such as a buoy tied to a rope, etc. shall be implemented.

(xv) Borrow pits will be left in a tidy state with stable side slopes and proper drainage in order to avoid erosion and ponding.

(xvi) It is possible that villagers may request borrow pits to left excavated so that they may be used as water reservoirs or fishponds. If this were to be agreed between the contractors and the villagers, all the full safety measures detailed above must be observed. Such agreements would be formalized in writing between the contractors and the villagers after full discussion with all concerned parties.


a. Terrestrial Ecosystem

592. In the construction phase, some activities in land clearance and vegetation removal would be continued. Activities in worker camp, construction of material stockpiles, construction of access roads, disposal of dredged soils etc. could damage vegetation cover

201

surrounded the project ROW. Additionally, filling up canals or water drainage systems at the wetland ecological zone, e.g at Can Gio, Nha Be, Nhon Trach districts may adversely affect the growth of mangrove trees. 593. As the area of trees that could be damaged by the above mentioned activities would not be large, the impacts on terrestrial ecosystem in the construction phase are expected to be minor and controllable. 594. To mitigate damage of the local terrestrial ecosystem the following measures will be implemented by contractors under the monitoring of the project owner and local authorities.

(i) Expanding the project ROW to the wetland and mangrove forest area particularly, at the Thi Vai river bank is forbidden.

(ii) Cutting trees outside the project area is forbidden. (iii) Prior to commencement of construction activities on site identify and mark

with suitable visual reminders the areas of mangroves that are not to be disturbed during the works. This measure is recommended for the construction site at the banks of Soai Rap, Long Tau and Thi Vai rivers where belts of mangrove trees occur.

(iv) Do not dispose dredging spoils and all types of wastes to upland/or mangrove forest areas.

(v) Do not fill up canals at the construction area without consultation with local authorities and environmental agencies.

(vi) Do not discharge oily wastewater to the surrounding environment. (vii) Prohibit workers from collecting firewood and construction materials from

surrounding forests, and from hunting wild animals.

b. Aquatic Ecosystems

595. Filling and leveling activities in road and bridge construction would cause various impacts on the local aquatic ecosystem. The main sources of the impacts are identified as follows.

(i) Filling up canals, ponds, wetland areas for road construction which would change local hydrology and reduce aquatic habitats. Consequently, animals, particularly fish; crustacean and mollusc species, would be reduced in composition and density.

(ii) Disposal of domestic construction and hazardous solid wastes from the construction sites to the surrounded canals and/or ponds would pollute the water environment and change the canal or pond bed structure. Consequently, the community of aquatic animals would be damaged.

(iii) Discharge of untreated domestic and industrial wastewater from worker camp, concrete preparing machines and from fuel storage sites would pollute receiving water sources. Consequently, aquatic ecosystem of canals and/or ponds would be damaged.

(iv) Leakage of acidic water and run - off water from construction sites at acid sulphate soil areas would acidify water in the receiving pond and fields. Consequently, aquatic animal species particularly shrimp and fish would be killed.

596. All above predicted impacts may be found at the large - sized construction projects in various provinces. In the Ben Luc - Long Thanh Expressway project these impacts are assessed as medium (in case of poor implementation of the Environmental Management Plan - EPM), but as minor (in case of proper implementation of EMP. These impacts are expected as local, temporary and mitigable.

202

597. To avoid or minimize the impacts on aquatic ecosystem the following measures will be implemented.

(i) Do not fill up canals and ponds without consultation with local authorities, people and environmental agencies.

(ii) Proper treatment of all types of domestic and industrial wastewater to comply with the Vietnam Standards/Technical Regulations for Effluents prior discharge into the surrounding environment. Technical measures for waste water treatment are indicated in above section.

(iii) Dispose domestic, industrial and hazardous solid wastes into the surrounding canals, ponds, forests is forbidden. Proper domestic and hazardous solid waste management is recommended in above section.

(iv) Proper treatment of strong acidic water generated from acid sulphate solid areas prior to discharge into the surrounding ponds, canals and fields used for aquaculture, water supply or protection of aquatic life. Technical measures for treatment of acidic water are shown in above section.

3. Socio-Economic Environment

i. Construction Worker Influx and Unplanned Migration

598. During construction activities, a peak workforce of approximately 1,000 construction workers will be required on site in the duration of over 60 month period. While strategies to ensure that local people are employed as part of the construction workforce will be implemented, the large number of workers required coupled with high levels of employment in the project area and thus the relatively small available workforce, means that many of these workers will not be local to the project area. 599. Potential positive effects of the influx of construction workers will include demand for retail and other services, which may result in increased economic activity and benefits for some local businesses including food suppliers and other retailers. 600. Potential negative effects of a large influx of large workforce of predominantly male workers will include increased socially undesirable activities, conflicts between residents and new comers, increased stress on services and infrastructure and environmental effects of construction worker camps. 601. Large influx of workforce may cause disease transfer between local residents and workers and vise versa. The common epidemic diseases may be affect to public heath are flu, water born diseases, HIV/ AIDS. 602. Introduction of the new workforce may cause feelings of tension between established residents and the newcomers. This may particularly be the case if newcomers feel excluded from opportunities offered by the project in terms of employment. The high existing levels of employment in the project area should minimize possible tension; however the potential for them to occur should be anticipated and planned in proactive way, by giving preference to hiring local persons if they have appropriate skills. The introduction of a new large population will increase pressure on existing services, particularly pressure on clean water supply solid waste management and energy provision. 603. Environmental effects of construction worker camps may include water quality deterioration from wastewater discharge, odor and vermin problems from poor solid waste management and general health and safety concerns if camps are not maintained in an orderly fashion. As noted, the locations of the temporary workers camps have not yet been determined; however they are likely to be located on the places not far from the existing residential areas.

203

604. Often the commencement of large infrastructure projects can precipitate high levels of unplanned migration from other areas and households move to the area in the hope of direct or indirect employment or other benefits, such as claiming land compensation. In this case of the Project, it is anticipated that unplanned migration will be relatively low due to a range of factors. Firstly, throughout the broader project area and surroundings, economic conditions are relatively good with low levels of unemployment due to the wide range of job opportunities in the industrial and service sectors. Thus, the numbers of households prepared to move to the vicinity of the project site on the hope of employment may be less than in other more economically disadvantaged areas. Secondly, the Resettlement Policy (RP) contains a provision that persons moving to the area after the completion of the detailed measurement and census survey, which will follow completion of the detailed design of the Project, will not be entitled to compensation by the Project. This approach will assist to reduce households moving to the site during construction activities in the hope of claiming land compensation. 605. To minimize the above predicted negative impacts the following measures will be implemented.

(i) Implementation of measures to maximize local employment to minimize the numbers of non-local workers employed at the project site. Severely affected and vulnerable affected persons will be given priority in gaining employment in the works. As a minimum, in each severely affected household, one person of working age will be prioritized in gaining employment during the construction phase. Individual households will identify the member best placed to benefit from this measure. This requirement will be included in the contractor's contract. In addition to this contractual requirement, the contractor will be encouraged to hire additional appropriately skilled workers.

(ii) In recognition of the fact that despite implementation of the above measures, large numbers of non-local workers will still be required, construction contractors will work with the local authorities to develop a range of measures to minimize the adverse effects of the planned construction force and unplanned migrants.

(iii) In order to protect workers health, construction contractors shall take measures as follows: a) supplying sufficiently clean water for domestic use and providing safe food supply. For the construction sites far from water sources, contractors will use tank trucks for transporting clean water to worker camps; b) storing clean water in containers made of stainless steels, cement or composite with covers; c) keeping clean kitchens and canteens, covering up foodstuffs against rats, flies and the like; providing hand-wash facilities at canteens.

(iv) In order to prevent epidemic diseases such as water-borne and vector-borne diseases, HIV/AIDS, transmitting from workers to local inhabitants and vice versa, the measures to be taken by construction contractors include: a) providing a medical station at every construction site to give drugs, health care, first aids, etc. in case of sickness or work accidents; b) educating construction workers in preventive measures (particularly HIV/AIDS) with special attention to new flu such as H5N1, H1N1 and other epidemics. c) organizing workers for killing pathogenic vectors such as flies, mosquito, rats, etc; d) cooperating with medical stations of communes and districts for health care and preventive medicine, and periodical health check (twice per year).

(v) Construction contractors shall sign contracts with environmental service units of districts for collection of garbage from workers’ camps and disposal at local dump sites. The frequency of collection shall be at least once every two days.

(vi) The solid waste management measures at construction sites are as follows: a) Segregation of solid wastes into domestic waste, construction waste and hazardous waste (oil and grease and chemical contaminated waste); b)

204

Installing labeled bins/containers for solid waste storage: blue container for domestic waste, red ones for hazardous waste and yellow ones for construction waste; c) Transporting segregated solid wastes by local environmental service units to disposal sites by means of separate containers.

606. In order to avoid conflicts between construction workers and local inhabitants, construction contractors shall take measures as follows:

(i) Employing as many local laborers as possible for simple jobs such as digging, leveling, handling materials, cooking, etc.

(ii) Educating construction workers in interrelationships with local inhabitants. (iii) Well fill up holes, borrow pits to prevent health risk and delete vector growth

places. (iv) Declaring temporary residence of workers with communal polices. (v) Periodically (once every two months) holding discussions with district PCs

about relationships between workers and local inhabitants. (vi) Educating workers in morality, industrial behavior and healthy life; strictly

managing the work force to avoid alcoholism, gambling and fights among workers and between workers and local inhabitants.

ii. Impacts on Cultural Heritage Sites

607. So far, archaeological study at the project's ROW was not implemented, yet and this study is not planned for the coming years. Therefore, impacts on archaeological values associated with the Ben Luc - Long Thanh Expressway Project is unknown. To avoid the impacts of road and bridge construction on archeological values the following measures are suggested.

(i) Alert district or provincial Departments of Culture - Information and Tourism on discovery of any objects of possible archaeological significance that may be uncovered during construction.

(ii) Immediately suspend construction activities affecting the area of the find until a qualified site assessment has been made and contractors have been given permission by the cultural management authorities to process.

iii. Health and Safety Risks

608. During the construction stage health and safety of local residents and construction workers may be adversely affected by the following activities. This impact depends on organization of construction activities and distance from the construction sites/impact generators and the receptor, but they are expected as medium or minor and mitigable.

(i) Noise pollution, generated by truck movement at dense populated areas and/or construction machines (bulldozers, trucks, air compressors, compactors, excavator, hammer drill etc.). Strong noise pollution (noise level of over 80 dBA) can cause stress in children and raise blood pressure, heart rates and levels of stress.

(ii) Dust (particulate matters) pollution generated by earth work activities and truck movement. Airborne high dust concentrations may cause inhibited lung function, deficit in pulmonary function, lung diseases and even increased acute respiratory morbidity for adults.

(iii) Chemical hazards generated by exhaust emissions containing high concentration of SO2, CO, XOx, VOC, PAHs from construction equipment trucks and painting, which may cause lung diseases and other chronic diseases.

205

(iv) Accident risks may occur by improper implementation of safety regulations: shortage in provision of workers; workers do not comply the safety regulations, accidents caused by electric shock or other reasons etc.

609. To minimize the above predicted impacts to public health the following measures will be implemented by construction contractors.

(i) Properly implement measures for noise control suggested in para 558. (ii) Properly implement measures for air pollution and exhaust emission control

suggested in para 527. (iii) Sufficiently provide personnel protective equipment for workers, particularly

for those working at sites with high noise or vibration, or close to electric sources and at bridge construction sites.

(iv) Set up a medical point at each construction team of above 200-300 workers to be responsible for first aid and emergencies; cooperate with commune's medical stations in treatment of safety risks for local residents and construction workers.

(v) Barriers (e.g., temporary fence) shall be installed at construction areas to deter pedestrian access to these areas except at designated crossing points.

(vi) The general public/local residents shall not be allowed in high – risk areas, e.g., excavation sites and areas where heavy equipment is in operation.

iv. Community Disturbance

610. All PCs, FFCs at 15 project's communes and almost all of the interviewed local residents support this project. However, all of them require the project owner and its contractors to solve the expected impacts on local socio-economy and environment due to the project's implementation which may create various disturbances on the local community. The major concerns on community disturbance are as follows.

(i) Land acquisition and resettlement, which are assessed in Section V.B.3. (ii) Environmental pollution caused by road and bridge construction affecting their

water, air, public health, cultivation, aquaculture and business which is assessed in Section V.C.1.

(iii) Influx of construction workers, affecting on local culture and environmental quality which is assessed in Section V.C.3.

611. To minimize the expected community disturbance the following measures will be implemented by VEC/PIU3 and its contractors.

(i) Thoroughly prepare and implement a RAP complying with the Vietnamese

Laws, ADB principles and requirements of local government and residents. (ii) Prepare and implement a Grievance Redress Mechanism (GRM) related with

resolution of claims of PAHs in environmental performance. The GRM suggested in this EIA report shall be notified to local PCs, FFCs and residents prior to commencement of the construction stage.

(iii) Properly implement all countermeasures proposed in this EIA report and the EMP of this project to mitigate all potential impacts which may be generated during the pre-construction, construction and operation stages.

(iv) Contractors/PIU3 shall provide information for commune's PCs and local residents (in written form) on the construction plan, including activities which may cause serious environmental impacts: location of worker camps, location of construction sites, date of construction, access roads for material transport, location of spoil disposal sites etc...

(v) Contractors/PIU3 shall closely cooperate with local PCs, DONREs, relevant authorities and the PAHs in solution of all socio-economic and environmental impacts generated during the project implementation. With proper

206

implementation of the measures given in the EMP, disturbance to the local community from the project will be minimized and the project will be strong supported by local stakeholders.

D. Impacts in the Operation Stage and Mitigation Measures


a. Vibration

612. In the operation phase, the very high traffic density of Ben Luc - Long Thanh expressway is the main generation source of vibration, particularly when heavy trucks are running. According to the EIA study for Ho Chi Minh City - Long Thanh – Dau Giay Expressway Project (the Center for Traffic Environmental Protection, 2007), the vibration of the expressway is predicted as follows. L = L0 - 10.log(r/r0)-8.7.a(r-r0) Where: L(dB) is vibration at the point at the distance r (m); L0(dB) is vibration at the point at the distance r0 (m); a: vibration reduction coefficient of soil (a= 0.01 for stone, 0.1 for sandy, muddy soil and 0.5 for clay). The foundation of the expressway is constituted of sandy and muddy soil (according to TEDIS) then a = 0.1. 613. Computed results are given in Table V.31.

Table V.31: Prediction of Vibration Pollution

Vibration of road basement Distance from road edge (m) Sandy /muddy soil Clay

10 93.00 93.00 20 69.97 10.82 25 64.25 Very low

Source: Center for Traffic Environmental Protection – Ministry of Transport, 2007. 614. Computing results in Table V.31 show that with the foundation is sandy/muddy soil, the vibration at a point 25 m in distance from the expressway edge (64.25dB) meets the Vietnamese Standard (TCVN 7210-2-2) applicable to vibration (65 dB). If the foundation is clay, the vibration is far lower and can meet the standard for residential areas when the distance is less than 20 m. 615. It is planned that the safety distance is 28.75 m from the expressway edge. As such, residential areas near the expressway will not be affected by the vibration during operation of the Ben Luc - Long Thanh expressway. Therefore, specific measures for vibration control are not required.

b. Air Pollution due to Vehicle Emission

i. Options of Assessment of Environmental Impacts due to Traffic Emissions

616. Pollution due to traffic emissions is an important matter that shall be predicted. In this EIA study, the prediction of air pollution due to traffic emissions is considered in two options; with and without the expressway. 617. In this case without the expressway, vehicles from Ben Luc to Long Thanh and vice versa will utilize the route as follows: National Road 1A → the East-West Expressway, Ho Chi Minh City → Long Thanh - Dau Giay → National Road 51 → Long Thanh with over 85km in total 618. In the case with the expressway, the total length of the route from Ben Luc to Long Thanh is 58km only (27Km shorter than that of the Option I). Therefore, the fuel consumption is lower, the economic efficiency is higher and environmental impacts are reduced.

207

Additionally the Ben Luc - Long Thanh Expressway can lessen the occurrence of traffic jams and at the same time, boost the transport speeds on the roads that link the East and the West of Ho Chi Minh City Region. 619. Nevertheless, the operation of Ben Luc - Long Thanh expressway will increase air pollution at 15 communes along it. Therefore, the increase in roadside pollution along the road shall be predicted.

ii. Environmental Efficiency of the Project

620. The environmental efficiency of the Ben Luc - Long Thanh Expressway is expressed by the reduction of pollution loads when it is exploited. In an attempt to evaluate the efficiency, the consultant has calculated the pollution loads of traffic emissions in 2 options, i.e. with and without of the project. The parameters used in the calculation are as follows:

(i) Pollution loads: the pollution loads of vehicular emissions at every speed range are calculated based on the tools integrated in a software product called OSPM (Operational Street Pollution Model), which is developed by Danish Environmental Research Institute (DERI). Calculated results are given in Table V.31 and a diagram illustrating the relationship between vehicular speed and discharge coefficient of the representative parameter (CO) is shown in Figure V.12.

(ii) Run length: The run length of the project alignment is 58km and when the project is absent, it is 85km.

(iii) Speed: the average of vehicular speed on the expressway is set at 110km/h (designed speed 120Km/h) and when the project is absent, it is 50km/h.

(iv) Average traffic flow: The predictions of traffic development in the projected expressway in 2016, 2026 and 2036 (by KEI and associates, in project ADB TA7155-VIE, August 2009) are used to determine the average traffic flow on the expressway.

(v) Fuel: It is estimated that 50% of vehicles consume gasoline and the other 50% consume oil.

The results in Table V.34 indicate that with the project, the pollution load of NO2 from vehicles running from Ben Luc to Long Thanh may be reduced up to 543.4kg/day (198.3 ton/year) in 2016 and 2,314.3 kg/day (844.7 ton/year) in 2036. Similarly, pollution loads of dust, benzene and CO will decrease significantly with the presence of the project. Particularly, the pollution load of CO will substantially decrease (more than 50%) with 44.9 ton/day reduced in 2036. 623. The above information indicates that the environmental efficiency (air pollution reduction) of the Ben Luc - Long Thanh expressway project is very high, with less environmental pollution from unnecessary fuel consumption due to current traffic congestion on the road from Ben Luc to Long Thanh.

iii. Air Pollution due to Traffic Emissions on the Expressway

624. As computed and compared above, the pollution loads of vehicle emissions on the expressway will be cut down significantly. Nevertheless, the expressway will generate air pollution in its vicinity. In an attempt to predict the increased air pollution, the pollution dispersion model ISC3 is used in order to compute the increase of pollution. The description of the model, its application conditions and computing results are given below. 625. ISC3 is software for computing air pollution diffusion in conditions of complex topography and weather. ISC3 was established and developed since 1980’s with the support of US Environmental Protection Agency (EPA). 626. ISC3 has an almost indefinite capacity to cover various kinds of emissions sources, for instance point source (air flue), spatial source (coal yard), open source (gas discharge gate), line source (traffic), as well as types of pollutants (TSP, PM10, SO2, NO2, NO2, CO, THC, Toluene, offensive smell, etc.). ISC3 can help compute the pollution diffusion over hundreds of kilometers of various terrains (plain, hill, mountain and coast, etc.) and complicated weather for every hour or day. 627. To date, ISC3 v.2000 is the most updated version, issued in 2000-2001. ISC3 is accredited and used by environmental agencies of the US, Australia, China, Japan and European Union as well as international organizations such as WB, ADB. In Vietnam, ISC3 has been used for predicting the industrial pollution diffusion for the Southern Focal

210

Economic Zone in 1997 and 2002 (a project managed by the Environmental Protection Department), the Central Focal Economic Zone in 2000 (also under the Environmental Protection Department), industrial projects (thermal power plants, cement) and some traffic projects (the East-West Expressway in Ho Chi Minh City). 628. ISC3 also utilizes other algorithms developed by Willis and Deardorff (1981), Snyder et al. 1985, Briggs (1993) for prediction of vertical and transversal diffusion in atmosphere. Input parameters of the Ben Luc – Long Thanh Expressway are:

(i) Source of emissions: line source. Because the length of expressway is 78 times as large as its width, it is divided into sub-section of 2 km each for application of the ISC3.

(ii) Location of sources: in the longitude/latitude coordinates, UTM, VN-2000 (iii) Technical parameters of sources: as for traffic sources with the pollution loads

in 2036 (the largest) (iv) Pollutants: the pollutants in the project include smoke (from burning of fuels),

road dust, NO2 and SO2 (because CO is far lower than the limit set forth in the Vietnamese standard, there is no need to include it in the computation).

(v) Topographical parameters: the basic terrain is plain with reference to DEM or XYZ digital maps.

(vi) Climate: wind speed and direction, humidity, radiation, etc. with data as given in Chapter Two, this EIA report.

(vii) Computing zones: Results are projected to the coordinates compatible to those of the source, in the distance of 1000 m from the centerline of the expressway. The grid of results may contain up to thousands points for each computing sub-section (2km).

(viii) Results: The results from ISC3 are included in a data file showing the distribution of pollutants in the computing zone and concentrations of pollutants in a day.

(ix) Result treatment: The result for the entire expressway is the sum of computing sub-sections. The result is treated with GIS software in order to incorporate it with maps of population, agriculture, urban areas, forest, etc. and to make specific maps showing the impacts of pollution diffusion from vehicles to the vicinity.

(x) Baseline database: The baseline data is taken from the air quality monitoring results obtained by the EIA Team in May 2009 over the entire alignment, the sampling sites of which are in accord with each section of the project expressway.

(xi) Technical data of the expressway: length: 58,000m, average width: 73m 629. Computing results of NO2 dispersion at various sites at typical cross-sections at the Ben Luc - Long Thanh expressway are given in Table V.35 and the variation of NO2 concentrations at the centerline and 10 m distance from the centerline are illustrated in Figures V.13 and V.14, respectively. 630. A diagram showing the distribution of NO2 pollution over the entire expressway and the typical cross-sections of some sections are shown in Figure V.15.

- R+60m 10 m from the right edge (60 m from the centerline)

631. Computing results of NO2 diffusion at sections of the entire Ben Luc - Long Thanh expressway show that:

(i) The distribution of NO2 at cross-sections inclines to the left of the centerline because of the dominant wind direction and the traveling direction of vehicles.

(ii) The increase of NO2 concentration at the distance of 50 m on the left varies from 15.7 μg/m3 at Section 7 (Phuoc Thai commune in Long Thanh district) to 23.4 μg/m3 at Section 1 (My Yen commune in Ben Luc district, Long An provine).

(iii) The increase of NO2 concentration at the centerline is 17.3 μg/m3 at Section 2 and up to 29.1 μg/m3 at Section 3 (Da Phuoc to Nhon Duc communes).

(iv) In comparison with the permission limit in the Vietnam National Technical Regulation for Ambient Air Quality (QCVN 05:2009/BTNMT) and limit value of

212

WB/IFC Guidelines is 200 µg/m3, the highest increase of NO2 at the centerline of Section 3 is only 14.55% of the limit and the lowest one at the left edge of Section 7 is 2.6% only. That means there is no risk of NO2 pollution (i.e. exceeding the standard) due to the presence of the project.

(v) When compared with the baseline NO2 concentrations, the lowest increase at the right edge of Section 7 is 3.4 %, and the highest one at the centerline of Section 6 is 74%.

(vi) When the baseline concentration is added (to evaluate the combined effect of traffic emissions and NO2 pollution in the existing environment), the predicted NO2 concentration in the air will fall in the range of 42.9 μg/m3 (at the distance of 23.5 m from the edge of Section 6) and 183.0 μg/m3 (at Section 4, i.e. the highest). At the latter point, the NO2 concentration measured in the monitoring course of May 2009 was 150μg/m3. Thus, even when the baseline concentration of NO2 is added, the total NO2 concentration in the air over Ben Luc – Long Thanh expressway is still lower than the permissible limit set forth in QCVN 05:2009/BTNMT and in WB/IFC Guidelines (permissible limit = 200 µg/m3).

632. Computing results of SO2 dispersion at various sites at typical cross-sections of sections of Ben Luc - Long Thanh expressway are given in Table V.36 and the variation of SO2 concentrations at the centerline and 50 m distance from centerline (i.e. 13.5m from the edge) are illustrated in Figures V.16 and V.17. 633. A diagram showing the distribution of SO2 pollution over the entire expressway and the typical cross-sections of some sections are shown in Figure V.16.

634. Computing results of SO2 diffusion at sections of the entire Ben Luc - Long Thanh expressway (Table V.34) show that:

(i) The distribution of SO2 at cross-sections inclines to the left of the centerline because of the dominant wind direction and the traveling direction of vehicles.

(ii) The increase of SO2 concentration at the distance of 60 m from the centerline varies from 8.9 μg/m3 at Section 7 (IC7 – IC8) to 16.4 μg/m3 at Section 4 (IC4 – IC5).

(iii) The increase of SO2 concentration at the centerline varies in the range of 14.3 μg/m3 at Section 7 and 19.0 μg/m3 at Section 5 (IC5 – IC6).

(iv) In comparison with the limit set forth in the Vietnam National Regulation (QCVN 05:2009/BTNMT), the highest increase of SO2 at the centerline of Section 3 (Da Phuoc to Nhon Duc) is only 6.3% of the limit and the lowest one at the right edge of Section 7 is 3.4 % only. That means there is no risk of SO2 pollution (i.e. exceeding the standard) due to the presence of the expressway.

(v) When compared with the baseline concentrations (May 2009), the lowest increase at the right edge of Section 7 is 1.7% higher yet the highest one at the centerline of Section 6 is 110%.

(vi) When the baseline concentration is added (to evaluate the combined effect of traffic emissions and SO2 pollution in the existing environment), the predicted SO2 concentration in the air will vary in the range of 19.8 μg/m3 (at the distance of 60 m from the centerline of Section 6) and 218.9 μg/m3 (at Section 7). All the predicted values are within the limit set forth in the Vietnam National Technical Regulation QCVN 05:2009/BTNMT (permissible limit = 350 μg/m3). The WB/IFC Guideline for SO2 is not used for evaluation as it relates to 10 minutes or 24 hrs averaging period, but not for 1 hour averaging period.

T+150m At 150 m on the left from centerline 636. From Table V.37 the following comments may be given:

(i) The increased CO concentration at the centerline at Section 8 (interchange with the Bien Hoa – Vung Tau Expressway) would be 570 µg/ m3 and at Section 3 would be 1,169 µg/ m3.

(ii) The increased CO concentration at the road edge (25 m from the centerline) would be 571 µg/ m3 (at Section 7) to 1,172 µg/ m3 (at Section 3).

637. Regarding the prediction of dust pollution, it is noted that there are two kinds of traffic dust:

(i) Dust in vehicle emissions (calculated based on the emission coefficients of the fuel burning),

(ii) Road dust: resulted from tire abrasion and arising out of road surface. (iii) The emission coefficient of road dust applies for Ben Luc - Long Thanh

expressway is 0.115g/km.PCU (for road surface covered with bitumen concrete) (according to US EPA).

639. Computation results of dust diffusion at sections of the entire Ben Luc - Long Thanh expressway given in Table V.38 show that:

(i) The distribution of total TSP at cross-sections inclines to the left of the centerline because of the dominant wind direction and the traveling direction of vehicles. Road dust is less affected by wind and the traveling direction.

(ii) The increase of total dust content at the distance of 50 m from the left edge varies from 24.47 μg/m3 at Section 7 to 62.56 μg/m3 at Section 4.

(iii) The increase of dust content at the centerline varies in the range of 37.51 μg/m3 at Section 7 to 60.77 μg/m3 at Section 3.

(iv) In comparison with the permissible limit guided in the Vietnam National Technical Regulation for Ambient Air Quality (QCVN 05:2009/BTNMT) for 01-hour averaging period, the highest increase of dust at the left edge 50 m distance from the centerline of Section 4 is 20.85 % of the limit and the lowest one at the right edge 60 m distance from the edge of Section 7 is 8.15% only.

(v) (Comparison of the obtained data of TSP (total dust) with the WB/IFC (WHO) guideline is impossible due to WB/IFC (WHO) does not have guideline for TSP but only for PM10 and PM2.5 (see Appendix II.2)

(vi) When the baseline dust concentration is added (to evaluate the combined effect of traffic emissions and pollutants in the existing environment), the predicted dust content in the air will vary in the range of 234.6 μg/m3 (at the right edge distance of 60 m from the centerline of Section 7) and 657.8 μg/m3 (at the right edge of Section 1, i.e. start of the expressway). All the predicted values in sections 1, 2, 4 and 7 are higher than the permissible limit in QCVN 05:2009/BTNMT (limit = 300 μg/m3), the reasons is the dust concentration of the baseline in sections 1, 2, 4, 7 exceeded the permissible limit in QCVN 05:2009/BTNMT (limit = 300 μg/m3) and the main source of dust pollution in those sections is dust from the other sources (dust dispersed from uncovered road, road surface, construction sites, under construction road). In locations where baseline levels are below the prescribed limit (as sections 3, 5 and 6) modeling results show that dust levels will not exceed applicable standard QCVN 05:2009/BTNMT (limit = 300 μg/m3 for 01-hour average) during operation. However, dust emission from road surface could also be attributed to the Project since dust suspension is also caused by vehicular movement when the road is operated in bad maintenance condition

Forecasted for Year 2036)

Figure V.22: Variation of Dust Content at the 60 m to Left Side form the Centerline

(Predicted by Traffic Flow Forecasted fro Year 2036)

640. From above information it may find that the main sources of dust pollution at the areas surrounded the existing roads (NH1, NH 50, NH51...) are dust from dirty road surface, dust from construction sites near by and from industrial enterprises. Dust from old vehicles is also a reason. Therefore, to minimize dust pollution effectively the following measures are suggested.

(i) Regularly repair road surface to ensure it is fully coved by asphalt-concrete layer but not by earth.

(ii) Do not permit vehicles, what do not comply with the Vietnamese Air Emission Standard for Vehicles, to operate on this expressway.

(iii) Properly implement air pollution control at construction sites and industrial enterprises.

641. The above proposed measures may have high effectiveness with the following conditions.

222

(i) The Expressway Management Company of VEC will well implement measure (i). (ii) The Vietnam' Registering Authority will strictly check and give licence for vehicles

following the Vietnamese Standards. (iii) The Provincial Transport and Environmental Polices strictly check and monitor air

emission from vehicles moving on this expressway. (iv) The provincial/ district DONREs strictly conduct air emission monitoring and

control at construction and industrial sites.

iv. Generation of GHG by traffic operation on the Ben Luc – Long Thanh Expressway

642. Green house gases (GHGs) will be generated by vehicles operating on this expressway. From the predicted number of cars, buses, trucks in Chapter III and based on the rates of Carbon dioxide emission from different types of vehicles, published in some international literatures, the amounts of CO2 generated at each section and at the whole Ben Luc – Long Thanh Expressway in the peak traffic operation (2036) is predicted (Table V.39).

Notes: Traffic volume: based on project forecasted traffic volume for year 2036. 1 car = 1 PCU (passenger car unit) 1 bus, struck = 3.5 PCU CO2 emission factor is taken from Table 5 in paper “Measuring the Invisible: Quantifying the Emission Reduction from Transport Solution, 31 December 2008. CO2 factor is used for case that EURO 4 Standard will be applied. From Table V.39, it may estimate that in year 2036, total amount of CO2 generated on the expressway is 1,462.864 ton/day or 533,945.36 ton/year, if the EURO4 standard will be applied.

643. Minimizing the GHG emission may not be done by the project itself, but by the policies of the Government in integrated environmental protection and development of transport. Some following general measures are suggested.

223

(i) Production and import of vehicles which have low GHG emission: before 2010 the

EURO4 for vehicles will be applied in Viet Nam. (ii) Promotion of development of vehicles which use liquid gases or other type of

fuels. (iii) Strictly check up air emission from vehicle engines, based on the existing and

updated Vietnamese Standards for Vehicle Emission (iv) Operation of vehicles which do not meet the Vietnamese Standard for Vehicle

Emission on this expressway is prohibited

c. Impact of Traffic Noise

644. Traffic noise is produced by the travel of vehicles on roads. It is dependent upon 7 factors as follows:

(i) Traffic density (ii) Traffic speed (iii) Composition of vehicles (iv) Road slope; (v) Pavement type and structure; (vi) Traffic conditions (vii) Noise level of each kind of vehicle.

645. The noise of a vehicle is the result of combination and interaction of various noises generated by:

(i) Engines; (ii) Movement; (iii) Braking apparatus; (iv) Interaction of tires and road face; (v) Components on frame and body of vehicle; (vi) Movement of the air flow around the vehicle.

646. The diffusion and impact of noise are dependent upon factors as follows:

(i) Road cross-section; (ii) Distance from the noise source to the receptor; (iii) Surface coating between the noise source and the receptor (for instance, grass,

water, concrete...) (iv) Natural or man-made obstruction objects; (v) Climate and weather. (vi) Impact of traffic noise

647. In order to assess the impact of traffic noise, 4 parameters are usually used:

(i) LA10: is the noise levels that are 10% exceeded for a sample period, usually 60 minutes.

(ii) Laeq: (Equivalent Continuous Level) is the equivalent continuous sound which would contain the same sound energy as the time varying sound.

(iii) LA90: is the noise levels that are 90% exceeded for a sample period. At these levels, the baseline noise level (initial sound) is minor.

(iv) Lamax: is the maximum sound from a single source.

224

648. Relations between parameters of traffic noise are illustrated in Figure V.23.

649. According to experienced data, traffic noise has properties as follows:

(i) A 3 dBA noise level increase is equivalent to a 0.5-fold increase in traffic flow. (ii) A 10 dBA noise level increase is corresponding to a double of sound intensity

sensed by hearing. (iii) A gear up/down by 10 kmph of a vehicle lead to a noise increase/reduction by 1

dBA. (iv) Effects of traffic noise exposure on human being are shown in Table V.40.

As mentioned in Chapter II, the Ben Luc - Long Thanh expressway in phase 2 will have 8 lanes with the designed speed of 80-120 kmph. According to Department of Main Roads (Australia), Road Traffic Noise Management: Code of Practice, 2008, an 8-lane expressway with the speed >97 km/g will produce the centerline noise level > 88 dBA (Table V.41).

Table V.41: Noise of Some Types of Road

No. Road type and speed Noise (dBA) 1 Street in a populated city 80 2 Street with designed speed of 56 – 65 km/h, 2 – 4 lanes with

traffic signals and left/right turns 82

3 Expressway with designed speed of 72 – 97 km/h, 2 lanes 86 4 Expressway with designed speed > 97 km/h, 4 - 8 lanes > 88 Source: Department of Main Roads (Australia) Road Traffic Noise Management: Code of Practice, 2008 651. In order to obtain a relatively precise prediction of traffic noise in the operation phase of Ben Luc - Long Thanh expressway, the EIA Consultant has utilized a noise diffusion computation software named SOUND32 for computation based on the traffic flow predicted for the year 2036 (8 lanes). 652. SOUND32 is a product of the Traffic Administration of California, USA. SOUND has been tested and allowed as a tool to evaluate noise to serve urban and traffic projects in California. With high accuracy and stability, SOUND32 is also in use for various researches, traffic development and construction projects in many countries all over the world. 653. From the computed noise levels indicated in Figures V.24 – V.26 it may be predicted that at the peak traffic period (2036) noise pollution would be significant problem at the road side areas. At all sections in a distance of 30m from the centerline noise level would meet the Vietnam Noise Standard for Mixed Residential, Commercial and Production area in Daytime (75dBA). For WB/IFC Guideline, it will take a distance of 100m from the centerline to meet the limited noise level is 70 dBA (for daytime and nighttime) for Mixed Residential, Commercial and Industrial. However, only in a distance of about 300 m from the centerline noise level would meet the Vietnam Standard for Nighttime (60dBA). 654. Comparing with the IFC/WB 2007 Guideline (WHO Standard,1999) at about 60 m from road edge noise level may meet the Standard for Industrial, Commercial Areas (70 dBA) in day – time and night time. Therefore, impacts caused by traffic noise pollution are assessed as major, long - term, but difficult to be mitigated. 655. To minimize noise impacts caused by traffic activities the following measures will be implemented.

(i) Building up noise control barriers at especially sensitive zones (hospitals, schools, pagodas, etc.) at the existing residential sites at 15 communes along the

226

expressway. This is a solution for reducing noise levels by possibly 10-15 dB(A). The ADB RETA 7155 - VIE has planned to construct wall barriers at the most sensitive noise receptors along the expressway. Total length of the barriers is 15,800 m. However, installation of noise barriers in front of residential houses may not be supported by local residents, because most of them do not like to have a wall in front of their houses. Therefore, construction of noise barriers will be done only upon official request of local district or commune' authorities. If control walls will be required by local people, the project owner will conduct detailed design and construct them at the noise sensitive places. Cost for noise control wall is very high: in USA cost of one mile of noise barrier is about 1.3 USD million.

(ii) Ensuring that all vehicles such as trucks, buses, cars and motorcycles meet the Vietnamese Standard of Noise for Road Vehicles (TCVN 5948 – 1999); as such, all vehicles running on the expressway shall have the licenses by Vietnam Register or competent authorities certifying their compliance to the noise standard.

(iii) Traffic Police regularly checking noise of vehicles and imposing regulatory fines to any vehicle that produces noise exceeding the allowable limit.

(iv) Do not plan and set up new sensitive noise receptors (hospitals, schools, churches, temples…) in a distance of less than 300 m from the road edge, where noise level exceeding the Vietnam’ guideline for residential sites in night time.

(v) Developing a traffic noise monitoring network: in cooperation with Departments of Natural Resources and Environment or the General Department of Environment, establishing a noise pollution map of the expressway for planning and construction of residential and urban areas adjacent to the expressway. This has been partially done in the computation and prediction of noise transfer in this EIA study.

656. The above measures (ii) and (iii) may be implemented without great difficulty, but the measures (i) and (iv) may not fully implemented because of various reasons:

(i) Measure (i) will not be accepted by great number of local residents and by high cost.

(ii) Measure (iv) may be applied for some new sensitive works (schools, hospitals) but this will not be practical with most of the existing and new works, due to at present within 50 m from the road edge from the starting to the ending points thousand houses of local residents existed and a number of new houses, schools, religious buildings will be constructed in the area within 10 -100 m from the road edge during and after construction of the expressway. The local authorities can not forbid this tendency.

657. With these reasons the Vietnamese and WB/IFC standards for noise at residential areas (50 dBA) would not be complied with in this project and in all other expressway projects in Viet Nam. From monitoring data collected by the EIA consultant for this project it was found that noise levels at residential sites within 10-50 m from the main roads in the cities at well as in rural area are usually 60 -70 dBA in day-time. In this range of noise pollution complaints from local residents were not recorded.

d. Road Pollution

658. The expressway may be polluted by waste matter carelessly thrown by passengers and drivers. In addition to pollution of the expressway, roadside fields and residential areas, such pollution can be unsightly on the expressway. This impact may occur but it is minor and mitigable.


659. In the operation stage biological environment may be affected by the following reasons.

(i) Run – off water from the road surface containing solid materials, grease and oil, which may pollute pond and fields receiving polluted water. Consequently, aquatic organisms maybe adversely affected. This impact is expected as minor, as contents of pollutants in run- off water may not be high.

(ii) Traffic emission containing air pollutants (dust, SO2, NOx, CO, Pb, and VOC) may cause air pollution which may affect vegetation and wild animal species. This impact is expected to be minor as air pollution caused by traffic activity is slight.

(iii) Induced impacts generated by high development of urban, industrial and tourist areas due to good traffic system connecting Dong Nai province, Ho Chi Minh City and the Mekong Delta. The induced impacts include increased air, water, soil pollution and reduction of wetland and forest areas. These impacts may directly damage natural habitats, biodiversity of flora and fauna. These impacts will not be directly created by this project and only be mitigated by the proper implementation of the policies of GOV in sustainable development and biodiversity conservation.

229

3. Socio - Economic Environment

a. Traffic Accident

660. Theoretically, traffic accidents on Ben Luc - Long Thanh expressway with 4 or 8 lanes, and without at-grade intersections, will have less chance to occur due to advanced traffic alarm systems. . However, because of poor implementation of traffic law and regulation in Vietnam, traffic accidents may occur as follows.

(i) Roadside districts/provinces open roads crossing the expressway. (ii) Residential or commercial areas planned or built encroach upon the safety

corridor of the expressway. (iii) Drivers have no experience of high-speed driving and fail to abide by the traffic

law, for instance, overdrinking, poor health or road-hogging, etc. (iv) Motorcyclists encroach on car-lanes, drinking, or road-hogging. (v) Pedestrians crossing the prohibited sections. (vi) Unclear traffic signals, failure of traffic lights, etc. (vii) Animals cross the road (viii) Poor quality of vehicles. (ix) Poor maintenance of road and bridges.

661. Traffic accidents may cause various social impacts:

(i) Different levels of disability or even fatalities for people. (ii) Lost work time, (iii) Lost money for treatment (iv) Damage vehicles and traffic signal systems.

662. In Vietnam in the recent years, annually over 12,000 persons died due to traffic accidents. The accidents happened mainly at highways. Therefore, traffic accidents are an important issue to be concerned during development of the Ben Luc – Long Thanh Expressway. 663. It is impossible to predict the severity of traffic accidents because it is dependent upon traffic management and people’s awareness with traffic laws and regulations. Nevertheless, the impact of traffic accidents is preventable by legal and technical measures. 664. In order to prevent traffic accidents in the operation of the expressway, the Ben Luc - Long Thanh Expressway Exploitation Company of VEC shall implement the measures below.

(i) Cooperation with the PCs of Ho Chi Minh City, Long An, Dong Nai: in prevention and control of: a) Planning and building up of any residential or commercial area that encroaches upon the safety corridor of the expressway; b) Opening access roads to the expressway; c) Commercial and living activities within the safety corridor.

(ii) Provision of pedestrian access across the expressway at locations of residential and/or commercial centers.

(iii) Proper maintenance of the expressway including a) Repair, rehabilitation and maintenance of the road face, basement, bridges and other construction works: this shall be done regularly to promptly remedy any damage and defect, etc. and maintain the expressway in the best conditions; b) Repair and maintenance of bridges: this shall include regular check of technical conditions of piers, beams, banisters, etc.; c) Full maintenance: this shall be done periodically (once every 5

230

years) in order to improve the quality of the road face and road adherence; d) Renewal: this is carried out after every 2 full maintenance cycles, including replacing the aged surface, i.e. the layer of 7 cm of bitumen concrete roadway;

(iv) Installation and maintenance of signals, sign, markings to regulate traffic, including posted speed limits, warning of sharp turn or other special road conditions, posts and road divider lines throughout the expressway

(v) Regular repair and maintenance of the lighting system. (vi) Movement of bicycles, motorbikes with designed speeds below 70 km/h and poor

quality vehicles on this expressway is prohibited. (vii) Regular checkup: the traffic polices of provinces that are crossed by the

expressway shall check up and impose stringent fines on any breach of the road traffic law, for instance, overloading, over sizing, over speeding, overtaking, illegal road crossing and others.

(viii) Well organized Transport Rescue Teams with suitable technical facilities to rescue the damaged vehicles on the road

b. Environmental Accidents

665. Environmental accidents (fire and explosion) may occur on the expressway, those include:

(i) Fire and explosion of fuel stations. (ii) Fire and explosion of trucks transporting fuels or inflammable chemicals.

666. The probability of the impact is low and in fact, it is possible to prevent and respond. 667. To minimize the potential environmental risks during operation of the expressway the following measures will be implemented.

(i) The Ben Luc - Long Thanh Expressway Operation Company shall cooperate with provincial police and Vietnam Register in regular checkup of safety systems and devices of fuel trucks running on the expressway.

(ii) Fuel stations shall be arranged at least 100 m from residential and commercial areas and in compliance with technical fire requirements stipulated by the Ministry of Public Security.

c. Upstream Inundation

668. If the drainage is not properly designed and built and canals become filled up, Ben Luc - Long Thanh expressway will become a 58Km dike that obstructs the upstream flow, (particularly in the North and northwest of the expressway). Consequently, upstream communes will be inundated in the flood season, production; trading and living of local inhabitants will be damaged. This phenomenon has happened previously at some highways in the Central Region and Mekong Delta. 669. To prevent this impact the following measures will be implemented.

(i) Proper control of culverts, so that water flow from upstream to downstream sides could not be stopped.

(ii) Do not fill up canals and/ or drainage systems in the area.

231

d. Impacts on Local People Due to Division by the Expressway

670. The expressway may create a physical barrier isolating villages, fields and residential sites along the road into two sides. This may obstruct local residents to get their fields, to visit their neighbours, to go to local administrative offices, and markets etc. This impact is expected as medium if the project does not implement suitable measures for mitigation. The obstruction by the expressway to the normal daily pattern of local residents will create strong complaints from communes’ authorities and residents. 671. This physical barrier may also obstruct animal crossing. However, this impact is small, since the number of domestic animals at the communes is small and very few wild animals are living at the project area. 672. To avoid the division of community by the expressway the project has planned and will design and construct a number of frontage roads, underpass and overpasses. These facilities were planned at the high populated areas and at the suitable sites for local residents to pass across the expressway. The location of frontage roads and underpasses, overpasses is indicated in the following tables.

e. Impacts of Induced Developments 673. Ben Luc - Long Thanh expressway will create favorable conditions for the fast development of cities, industrial parks, seaports, airports, commercial sectors and tourism in the Southeast Region and the Mekong Delta. As discussed above, those are major positive impacts of the project with the socio-economic points of view. 674. Nevertheless, the increases in urbanization, industrialization, the development of trade and tourism and the population growth along the expressway will trigger a series of negative environmental impacts. Those include:

(i) Increase of municipal and industrial wastes and creating increased pollution of the air, water and land.

(ii) Encroachment into the wetland areas when urban and industrial zones and tourist sites are expanded, particularly in Nha Be, Can Gio, Nhon Trach districts. It is possible to state that with reduction of wetland area the urban environment of Ho Chi Minh City will increasingly worsen with intensive water inundation in the flooding season; reduction of vegetation covers. Additionally the consequences of climate changes would be harder, adversely affecting production and health. With reduction of wetland areas, the biodiversity of Ho Chi Minh City, Long An, and Dong Nai provinces will deteriorate.

675. It is noteworthy that those negative impacts are not directly caused by Ben Luc - Long Thanh expressway. In fact, it depends much on the development of infrastructure for traffic, industry, urban areas and tourist sites of the provinces in the region. 676. A general concern is the increase in the number of tourists and vehicles accessing Can Gio Biosphere Reserve. However, this impact will not occur due to the expressway as it will not connect with Road 15 (Rung Sat highway crossing Can Gio mangrove forest) that is under construction by Ho Chi Minh City. There will be neither vehicles nor passengers coming to Can Gio district via Ben Luc - Long Thanh expressway. Therefore, any impact on biodiversity and ecosystems of Can Gio Biosphere Reserve will not be caused by this project. 677. For the mangrove forest along the Thi Vai river in Dong Nai province: since the project will build a viaduct passing over the forest, the operation of Ben Luc - Long Thanh expressway will not affect the mangrove ecosystems there. 678. The most important role in mitigation of degradation of natural ecosystem during the increased industrialization and urbanization in this region is the effective implementation of the following Laws and policies:

(i) Law of Environmental Protection (2005) (ii) Law of Forest Protection and Development (2004)

233

(iii) Law of Water Resource (1998) (iv) Land Law (2003) (v) Law of Biodiversity (2008) (vi) National Plan for Sustainable Development (2005) (vii) Vietnam Standards and National Regulation for the Environment. (viii) And other laws, governmental decisions, circulars of MONRE and policies of the

city/provinces in integration of environmental consideration into economic development.

679. Implementation of the above laws and policies is the responsibility of all governmental authorities, people and investors in the region. E. Specific Environmental Impact Assessment for Bridge Construction

680. Construction of bridges is a component of the Ben Luc - Long Thanh expressway project. It includes the following activities. a) in the pre-construction phase: site investigation, design, site clearance and resettlement, UXO investigation and removal; b) In the construction phase: transport of materials, construction of road and viaducts to the bridges, construction of bridges, construction of auxiliary facilities; c) in the operation phase: traffic over bridges. 681. Therefore, the environmental and socio-economic impacts of bridge component in 3 phases are basically the same as those of road construction that are predicted and assessed above. Therefore, this assessment of the impacts caused by on bridge component does not repeat such impacts. It focuses mainly on prediction of some specific environmental impacts related to land clearance for bridges and bridge construction.

1. Introduction of Bridges

682. Ben Luc – Long Thanh expressway will cross various rivers and canals in the districts of Ben Luc, Can Giuoc (Long An province); Binh Chanh, Nha Be, Can Gio (Ho Chi Minh City); Nhon Trach, Long Thanh (Dong Nai). Noticeably, Binh Khanh bridge over the Soai Rap river and Phuoc Khanh bridge over the Long Tau river are the two big ones; the others are small or medium. The list of bridges and hydrological parameters of the relevant rivers along the alignment of Ben Luc – Long Thanh are shown in Table V.44.

2. Impacts and Mitigation Measures in the Pre - Construction Phase

Physical Environment 683. In the pre - construction phase the main activities are design of the bridges, land clearance and implementation of resettlement. These activities would not cause negative impacts on the land, water and air environment. Therefore, assessment of the impacts on the physical environment and proposal of counter measures area not necessary. Biological Environment

i. Agricultural Ecosystems (rice fields and aquaculture land)

684. These ecosystems are prevailing at almost all communes affected by the land clearance. In detail, they exist at the sites selected for building up the bridges of Ong Thoan (Km2+225), and Chua (Km8+100) at Binh Chanh commune in Binh Chanh district; Can Giuoc (Km12+600) at Quy Duc commune in Binh Chanh district; Ong Nam (Km15+600) at Da Phuoc commune in Binh Chanh district. The site clearance for building the bridges will affect rice fields and aquaculture land alongside canals and rivers. 685. At the site for Ba Lao bridge, the site clearance will acquire a zone of aquaculture ponds. In the territory of Nhon Duc commune in Nha Be district, where bridges of Ong Cai (Km19+150), Tac Thay Cai (Km19+750) and Ba Minh (Km20+670) will be built; land acquisition will affect aquaculture ponds and rice fields, reducing the area of those wetland ecosystems. Similarly, the construction of bridges of Ngon Lap Dau (Km21+125) and Ca Noc (Km21+475) at Long Thoi commune in Nha Be district will occupy the area of aquaculture land and rice fields. 686. In the sites for the big bridge of Binh Khanh (Km20+400) at Long Thoi commune in Nha Be district and Binh Khanh commune in Can Gio district, the site clearance will affect aquaculture ponds, rice fields and secondary crops, reducing their areas. At Binh Khanh commune in Can Gio district, where it is projected to build the bridges of Song Cha Lon (Km26+150), Song Cha Nho (Km27+850), and Xom Quan (Km28+850), land acquisition and site clearance will affect aquaculture and rice cultivation, the latter of which covers a large area in the region. 687. Phuoc Khanh bridge is the second largest bridge following Binh Khanh bridge over the Long Tau river. Land acquisition at Binh Khanh commune for building viaducts will affect aquaculture and reduce the area of wetland ecosystems. At Phuoc Khanh commune in Nhon Trach district, Dong Nai province, where it is projected to build up the bridges of Thu Ho

235

(Km31+800), Ong Keo Lon (Km34+700), and Ong Keo Nho (Km35+400), land acquisition will affect the areas of rice fields and short-term industrial crops. 688. Land acquisition and site clearance for Dai Dien bridge (Km38+900) at Vinh Thanh commune in Nhon Trach district will affect rice fields amid short-term industrial crops. The projected site for the bridges of Vung Gam (Km43+150) and Ba Bong (Km45+550) at Phuoc An commune in Nhon Trach district is aquaculture land. At the projected site for Ben Ngu bridge (Km55+700) at Phuoc Thai commune - Long Thanh district, land acquisition will affect agriculture land and wetland. 689. All sites projected for bridges and viaducts at 15 communes of 7 districts are currently agriculture (rice fields) and/or aquaculture land, which belong to wetland ecosystems. Wetland is of economic and environmental significance as follows:

(i) It is the habitat and growth field for various flora and fauna species of high values of economy and biodiversity.

(ii) Its bio-productivity is high. (iii) It receives rain water and upstream effluents from urban areas of Ho Chi Minh

City, Long An, Dong Nai, storing water and treating polluted water. (iv) It regulates the hydrological regime and climate. (v) It is very sensitive to internal changes of the environmental factors and external

effects. 690. The reduction of wetland area due to the construction of the expressway and bridges would reduce the value of the natural ecosystem. Nevertheless, the wetland areas to be acquired for the bridges are minor (less than 10 ha in total) compared with the area to be acquired for industrial parks and urban areas in this region. As such, this impact is assessed as irrecoverable but minor.

ii. Natural Ecosystems

691. The investigation of the existing biodiversity and bio-resources of the study site of the entire Ben Luc – Long Thanh expressway has noted the following :

(i) At the sites projected for the bridges of Ong Thoan (Km2+225), Chua (Km8+100), Can Giuoc (Km12+600), Ong Nam (Km15+600), Ba Lao (Km17+100), Ong Cai (Km19+150), Tac Thay Cai (Km19+750), Kenh Bun Dua (Km20+125), Ba Minh (Km20+670), Ngon Lap Dau (Km21+125), Ca Noc (Km21+475), Binh Khanh (Km23+400), Song Cha Lon (Km26+150), Song Cha Nho (Km27+850), and Xom Quan (Km28+850), the natural vegetation cover has already been encroached upon for expandion of agriculture and aquaculture land. Therefore, the remaining vegetation is mostly strips and bands of brackish water species scattering on riversides, which include communities of Nypa fruticans and Sonneratia caseolaris, Aglaodorum griffithii, Derris trifolia. The site clearance in the pre-construction phase will cut off the remaining trees at the sites, thereby reducing the local biodiversity. Nevertheless, since the riverside ecosystems are poor in term of biodiversity, and the area of site clearance is limited, this negative impact is assessed as minor.

(ii) At the sites projected for the bridges of Phuoc Khanh (Km30+300), Thu Ho (Km31+800), Ong Keo Lon (Km34+700), Ong Keo Nho (Km35+400), Dai Dien (Km38+900), Vung Gam (Km43+150), Ba Bong (Km45+550), and Ben Ngu (Km55+700), the riverside mangrove ecosystems are changed with brackish water species replaced with typical saline water species with the prevailing of communities of Rhizophora apiculata, Avicennia alba, Excoecarta agallocha. The

236

destruction of riverside mangrove belts for building bridges would damage those ecosystems. Nevertheless, the results of the environmental surveys (Chapter III) show that the ecosystems are already deteriorated and the species number is limited. Areas of mangrove trees to be cleared at riversides of each river vary from about 1,500 m2 at Ben Ngu, Dai Dien, Vung Gam bridges to 2,000 m2 at Ong Keo Lon bridge and 3,000 m2 at Phuoc Khanh, Binh Khanh bridges. Therefore, the impact of site clearance for bridges on the ecosystems is minor.

(iii) The mangrove ecosystem appears only at the sites for the projected bridges of Thi Vai (Km53+100) and Tacdoi (Km54+200) at Phuoc An commune in Nhon Trach district - Dong Nai province. The forest structure there is simple with one layer of wooden trees (Rhizophora apiculata) of 5 – 10m height, 5 – 17cm diameter (12cm on average) and density of 100 to 500 trees per hectare. The dominant species of Rhizophora apiculata account for more than 95% and the remainders include Avicennia alba, Excoecarta agallocha, Nypa fruticans, Sonneratia caseolaris, Aglaodorum griffithii, Derris trifolia, Acrostichum aureum. This is the habitat of various bird species, some amphibian and reptile species, and a number species of fish, shrimp and mollusk. Site clearance for building up Thi Vai bridge and viaducts will remove a part of the vegetation carpet located in the ROW (approximately 3,000m2 to 5000 m2 in option of viaduct construction and at most 28 ha in option of construction of road to the bridge). Because the project has designed and will build a viaduct, this impact is assessed as minor. Furthermore, this impact can be minimized by the program of compensatory reforestation.

b. Socio-Economic Environment

i. Housing Loss for Building bridges

692. The survey of the EIA Team found that at the sites projected for the bridges on the rivers and canals of Chua (Km8+100), Can Giuoc (Km12+600), Ba Lao (Km17+100), Tac Thay Cai (Km19+750), Ba Minh (Km20+670), Ca Noc (Km21+475), Song Cha Lon (Km26+150), Song Cha Nho (Km27+850), Xom Quan (Km28+850), Phuoc Khanh (Km30+300), Thu Ho (Km31+800), Ong Keo Lon (Km34+700), Ong Keo Nho (Km35+400), Ba Bong (Km45+550), many households setting on the riversides. Particularly at the sites of Ba Lao (Km17+100) and Ca Noc (Km21+475), the number of the PAPs would be large. They will lose residential land and must relocate. Number of households to be affected by bridges construction is included in Table V.18. This socio-economic impact was assessed in Section V.B.3 (Socio-Economic Environment)

ii. Loss of Agriculture and Aquaculture Land

693. The environmental survey found that rice cultivation and aquaculture plays a major part in economic activities of people in the zones to be crossed by the expressway. Those exist at almost all sites for bridges. That means site clearance will affect the existing rice cultivation and aquaculture (mostly fish and shrimp culture). The acquisition of agriculture or aquaculture land will adversely affect the family economy of the PAPs. 694. At the site for the bridges in Nhon Trach district of Dong Nai province, i.e. from Thu Ho bridge (Km31+800) to Dai Dien bridge (Km38+900), in addition to rice cultivation, farmers also plant industrial crops such as cassava and cashew nuts. As such, land acquisition cause loss of production land, consequently, impacts on income of the PAPs. At the sites for the bridges of Vung Gam (Km43+150), Ba Bong (Km45+550), and Ben Ngu (Km55+700), land acquisition will affect local aquaculture.

237

iii. Overall Assessment on the Socio-Economic Impact of Site Clearance for Bridges Construction

695. The acquisition of aquaculture/agriculture and residential lands for building bridges and viaducts will cause negative socio-economic impacts on the PAP. The impacts are assessed and predicted in details in the RAP report of the project. They are inevitable but the areas of land acquisition for bridge construction are small and the overall impact is therefore minor and mitigable. 696. To minimize the adverse impacts of land acquisition and site clearance to the PAHs the RAP report of the ADB TA 7155 - VIE has suggested various policies and action plans. The project Resettlement Action Plan (RAP) was prepared based on the legal documents of Vietnam but it also complies with the ADB policy principles and requirement on Involuntary Resettlement. The project owner in cooperation with district's Resettlement Committees will implement the laws, regulations and policies of the Government, relevant city/provinces and the ADB policy to support the PAHs in resettlement, restoration of their production and improvement of their living conditions.

3. Impacts Associated with Bridges Construction


697. During bridge construction the following impacts would be produced.

i. Noise and Vibration

698. In the construction phase, noise will be generated by:

(i) Construction machines (ii) Concrete mixers (iii) Piling (iv) Transport of sand, macadam, steel and iron, and construction materials in

general (v) Electric generators

699. The impacts are similar with those of the construction of the expressway which have been predicted and assessed in above para 548 - 564.

ii. River Erosion

700. Main characteristics of rivers in the region include permanent availability of water, small slope of riverbed, dependency of water level upon seasons (dry and rainy) and tidal influence. The basin is lying over weak foundation (soft soil) and river banks are muddy and easily eroded. Therefore, bank erosion is possible during the construction of bridges. 701. The cause of erosion is water that erodes, digs and washes away materials of the riverbed and river banks. Erosion is a natural cycle; therefore, determination of erosion at the project area is very complicated. 702. In the construction of bridges, the main cause of narrowing is the flow constriction (encroachment) by the viaduct foundation or piers/pillars. Consequently, the flow passage is reduced; the speed and riverbed cut press increase. 703. Local erosion at piers/pillar or abutments is the washing away of bottom mud or sand by the formation of "horse-shoe" whirlpools at their foundations. Horse-shoe whirlpools are formed

238

when the upstream flow bumps into the obstructing face, increasing the current around the pier or abutment and consequently, the materials at their foundations are moved. In addition to horse-shoe whirlpools, there are downstream film whirlpools. Both kinds of whirlpools can wash away materials at the foundation. The intensity of whirlpools is quickly reduced when the downstream distance from the pier expands. Consequently, deposition of materials takes place in the downstream zone. 704. The factors affecting the depth of local whirlpools include:

(i) Speed of the inflow, (ii) Depth of the flow, (iii) Width of the pier, (iv) The flow stopped by the abutment, (v) Length of the pier, (vi) Dimension and particle distribution of bottom materials, (vii) Angle of the inflow, (viii) Shape of the pier or abutment, (ix) Riverbed status,

705. The erosion is predicted for the main bridges that have piers located in rivers, i.e. Ba Lao, Binh Khanh, Phuoc Khanh and Thi Vai. The flow used in the computation has the 1%, frequency of the record high in history. Because the analytical data of particle distribution, in this study, D50 and D95 are presumed at 0.015mm and 0.5mm, respectively as the data used in the designing of Long Thanh bridge (see the Hydrological Study Report on Ho Chi Minh City - Long Thanh - Dau Giay Expressway) with similar conditions taken into account. Nevertheless, in the phase of detailed design, the erosion prediction will be updated with relevant dimensions, i.e. actual D50 and D95 at each bridge. The predicted erosion of the bridges is shown in Table V.45.

The predictive results of erosion in Table V.42 and hydrological data in Table V.43 indicate that: at the project sites of Ba Lao bridge (Km17+100) where the flow rate and velocity are 1,296m3/s and 1.25m/s, respectively; of Binh Khanh bridge (Km23+400) with 11,500m3/s and 1.25m/s; Phuoc Khanh bridge (Km30+300) with 11,500m3/s and 1.25m/s; and Thi Vai bridge (Km53+100) with 3,748m3/s and 1.25m/s, the risk of erosion is very high. Therefore, it is essential to take appropriate measures to prevent and limit erosions, including pier erosion, abutment erosion and bank erosion. 707. In order to minimize river bank erosion the following measures will be implemented.

239

(i) At all bridge construction areas where may be eroded, embankments with solid

stone layer, will be constructed. The area of stone embankment at each site will be designed case by case.

(ii) At river banks closed to the bridge construction site vegetation carpet will be planted for soil erosion control. The length and width of tree belt for each bank at each bridge construction site is about 50-100*2-10m, depending on the actual situation at each site. The trees to be planted are Nipa palm (in Ben Luc, Binh Chanh and Nha Be districts), Sonneratia spp. and Nipa palm (in Can Gio district) and Rhizophora spp. and Sonneratia spp. in Nhon Trach, Long Thanh districts. Density of trees is 1.0*1.0m (for Rhizophora), 1.5*1.5m (for Nipa palm), 2.0*2.0m (for Sonneratia spp.). Area of mangrove trees to be cleared for bridge construction is estimated in Section IV.B.2.g (Chapter IV). Detailed calculation of vegetation areas to be cleared at each location will be done in the construction stage, based on construction options of each contractor. Therefore, replanting cost for each location will be calculated in detail at that stage.

(iii) Properly design and construct structures of piers and abutments to avoid soil erosion.


708. During bridge construction, activities such as drilling, pier piling, etc. will all cause negative impacts on water quality and aquatic ecosystem at the rivers. Those impacts include:

(i) Disturbance of water and river bed where is habitats of fish and mollusk species because of drilling, piling and concrete filling;

(ii) Increases in suspended solid (SS) organic matters heavy metals and oil from bottom sediment, because of pier construction activities. Consequently, the dissolved oxygen (DO) in water are reduced, turbidity and concentrations of toxic chemicals are increased with this water pollution, aquatic species (fish, shrimp, crab, etc.) at the construction site would be affected.

(iii) Oil pollution created by discharge of oily wastes and leakage of fuel from barges to canal or river.

(iv) Riverbed disturbance and changes of the structure and composition of zoobenthos in the site as a result of dredging.

709. In general, all impacts mentioned above are negative to aquatic organisms in the project site. Nevertheless, since the construction volumes of piers, abutments and waste matters will be small, those impacts are assessed as minor, local and temporary (during bridge construction only). After completion of construction, those impacts will no longer exist and the aquatic biota can be restored. 710. Due to impacts caused by piers/pillar construction on local water quality and aquatic ecosystem is minor and specific mitigation measures are not necessary to be implemented. However, to prevent water pollution caused by wastes from barges used for bridge construction the following measures will be implemented.

(i) Discharge untreated wastewater and release rubbish from barges to water is forbidden. The barge owners shall install wastewater collection and treatment system and rubbish bins. Solid wastes shall be periodically collected and transported to local disposal sites.

240

(ii) The barge owners participated in bridge construction for this project shall have an oil spill prevention and response plan and relevant technical facilities for its implementation.

(iii) Proper organization of barge operation so that navigation risk could not occur.

c. Socio - Economic Environment

i. Impacts on Waterway Transport

711. According to investigation results, the alignment of Ben Luc – Long Thanh expressway will cross 3 main branches of the Dong Nai – Sai Gon River, namely Soai Rap, Long Tau and Thi Vai. They are important waterways in the Southeast Region. 712. The investigation of the sites for the bridges of Can Giuoc (Km12+600), Ba Lao (Km17+100), Binh Khanh (23+400), Song Cha Lon (Km26+150), Phuoc Khanh (Km30+300), Ong Keo Lon (Km34+700), Ba Bong (Km45+550), Thi Vai (Km53+100), and Ben Ngu (Km55+700) found them having high density of waterway traffic. The most important waterway crosses the site of Binh Khanh bridge (Km23+400) on the Soai Rap River and Phuoc Khanh bridge (Km30+300) on the Long Tau River. They are two rivers linking the ports of Ho Chi Minh City, Dong Nai, Ba Ria - Vung Tau, and Long An to other ports in Vietnam and the World. 713. In the construction phase, the large number of construction machines for building the bridges, for instance, barges, piling machines, and others, will narrow the width of rivers or canals, obstructing the river traffic. This impact is assessed as minor to medium depending on the bridge site but temporary and possible to mitigate. 714. In case of construction of small bridges at narrow canals the activities in excavation, earthworks, stockpiling etc. on canal banks may cause obstruction of waterways. These impacts may be observed at some bridge construction projects in the Mekong Delta of Vietnam and in other countries. At these bridge construction sites, these activities may not only obstruct waterways, but also reduce canal water flow, causing stagnation, and deterioration of water quality. 715. To well prevent obstruction of normal waterway transport the following measures will be applied by bridge construction teams:

(i) Installation of machines for bridge construction (floating cranes, barges etc.) will be done within only the limit which will not encroach into the ship movement channel. This limit shall be agreed by the Vietnam Maritime Board or the DOT of the relevant provinces/city.

(ii) Installation of temporary signaling points to regulate boat movement at the bridge construction sites.

(iii) Proper cooperation with local Waterway Police in regulation of waterway transport and protection of the bridge's construction machines.

(iv) Water courses (rivers, canals) shall be kept free of excavation spoil and construction debris, floating and submerged.

(v) Spoil and construction materials stockpiles area shall be located away from water bodies and under no circumstances will these materials be dumped into watercourses.

716. Obstruction of waterways may result due to by excavation, earthwork or stockpiling during construction of the large bridges (Binh Khanh and Phuoc Khanh bridges). However, from observation at the large bridge construction projects, like Phu My bridge on the Sai Gon river (2006-2008), Can Tho bridge on the Hau (Bassac river) (2004-2009), Bai Chay bridge on the

241

Cua Luc Bay (2002-2005) activities in earth works, stockpiling did not cause obstruction of ship or boat movement, as materials were stored at the river banks far from navigation channels. Therefore, this type of impact will rarely occur during construction of Binh Khanh, Phuoc Khanh and Thi Vai bridges. Implementation of the above mitigation measures will avoid such impact.

ii. Impacts of Waterway Accidents

717. Movement of barges and operation of floating cranes for bridge construction, particularly at Binh Khanh bridge over the Soai Rap River and Phuoc Khanh over the Long Tau River, may obstruct traffic and accidents may occur. Nevertheless, this impact is avoidable because the investor and subcontractors will take proper managerial measures in the construction of bridges, particularly large ones. 718. To avoid this type of accident the following measures will be implemented by bridge construction contractors.

(i) Proper organization of construction activities at bridge's pier construction (installation of construction machines, barges etc at the place permitted by the Waterway Transport Authority) so that construction activities could not encroach into the navigation channels.

(ii) Proper management by the contractors in cooperation with Waterway Police for movement of barges/ships transported materials for bridge construction, so that interference between them and commercial ships or passenger boats would not occur.

(iii) Installation of rescuing facilities (oil collectors, hydrants, pumps, chemicals, fire extinguisher etc. for fire control, life buoys, etc.) at all barges/ships of the bridge construction contractors.

(iv) Setting up of temporary signaling stations to warn boats on any obstruction to traffic.

719. In case of oil spills the constructor shall immediately implement the following actions

(i) Inform the Sai Gon Port Authority, who is responsible for waterway transport in Ho Chi Minh City and surrounded region.

(ii) Inform to Oil Rescue Companies operated in the region of Ho Chi Minh City asking them to support in oil spill control.

(iii) Inform the communes which may be affected by oil spill dispersion, so that they could prevent water, land and economic damages.

(iv) Organize oil collection in cooperation with the oil rescue companies to minimize as much as possible oil dispersion.

(v) After control of oil spill the contractor will cooperate with the relevant local communes in treatment of water, land pollution and compensation for environmental and economic damages, following the relevant Vietnamese Laws and Guidelines, if oil spills came from bridge construction activities..

4. Impacts in the Operation Stage of Bridges

720. In the operation stage of bridges, main environmental impacts will be caused by traffic operation, including:

(i) Increased air pollution. (ii) Increased noise and vibration pollution. (iii) Increase in traffic accidents.

242

721. These impacts are the same as those of the operation of the expressway and predicted in above section. F. Preliminary Assessment of Impact of Climate Change

722. Climate change may affect the natural environment and socio – economic development of Viet Nam in general and the estuarine regions of the Dong Nai – Sai Gon river basin and Mekong river delta in particular. 723. As suggested by some scientists, Viet Nam will be one of 5 countries in the world to suffer the most serious consequences of climate change. The Mekong river delta and the Dong Nai – Sai Gon estuarine region may be seriously affected by the consequences of climate change. 724. The main consequences of climate change in this region will be:

(i) Increased drought in the dry season (ii) Increased flood in the rainy season (iii) Increased frequency of typhoons and other bad weather phenomena (iv) Increased sea water level rise.

725. Increase of sea water level rise would be the most serious consequence of climate change to this region. With the increased sea water level the following consequences would be expected:

(i) Soil and water in the inland area will be saline, causing constraints for water supply, agriculture, infrastructural facilities etc.

(ii) Reduction of agricultural, freshwater aquaculture land, causing loss in income of local farmers.

(iii) Damage on infrastructural facilities urban and industrial facilities. (iv) Damage on native ecosystems in the region. (v) Increased inundated area in the low land region. (vi) Increased diseases, particularly, epidemic diseases.

726. As preliminary prediction of MONRE (2009) the rise of sea level in the Mekong Delta Region would be + 30 cm in 2030, + 50 cm in 2050 and + 75 – 100 cm in 2100. 727. With the above prediction by the year 2100, the Ben Luc – Long Thanh Expressway would not be affected by the sea water rise due to the height of its embankment is 1.0 m higher than the high water (5%) predicted in year 2036. 728. However, with long – term inundation by seawater in the area surrounding the expressway, the road embankment could be eroded and damaged if not strong enough. 729. To minimize road damage caused by sea water inundation the road embankment will be designed and constructed, so that it will not be infiltrated by inundated water and the embankment heights may be raised in the future if necessary. 730. In case of high sea water rise, the physical barrier of the expressway may cause sea water inundation at the seaward side, creating adverse impacts on living conditions, agricultural production for local residents. However, this impact is expected as minor because the project has designed various culverts to create normal flow of flood water from upstream to downstream sides and vice versa.

243

731. To properly mitigate this impact in the design phase the design consultants will carefully study topographic, hydrological features and socio – economic conditions at each section to design sluices, underpass roads suitable for each site to assure normal flow of flood water from the sea and from the upstream side.

VI ANALYSIS OF ALTERNATIVES

A. Relation to National Strategy

1. Summary of Project Alignment

732. The Traffic Master Plan for development of the North – South Expressway is being implemented by the Ministry of Transport (MOT) through investment in several expressways including the HCMC – Trung Luong Expressway, Trung luong – My Thuan – Can Tho Expressway, and the Ho Chi Minh City – Long Thanh – Dau Giay Expressway. 733. The master plan of traffic development of HCMC for year 2020 and afterwards was approved by the Prime Minister (Decision No. 101/QĐ-TTg dated 22/01/2007), and the Ben Luc - Long Thanh expressway is one of six expressways located near HCMC and its surrounding areas. (Figure 1, Chapter I) 734. Running pass HCMC, the North - South Expressway will link to the Ring Road 3 (RR3). If the project alignment link to RR3 to the Western Region was through Cu Chi district to Binh Duong province and Bien Hoa city, it would have an advantage on topography and geology, however, it would not efficiently service the developed economic areas such as Nhon Trach - Long Thanh, Thi Vai ports and Cai Mep ports at the Eastern Region. Therefore, the connection of the project alignment and the North–South expressway at HCMC to the Southern Region through Ben Luc to Nhon Trach will be consistent with the traffic master plan approved by the Prime Minister.

2. Do Nothing Option

735. This expressway is class A with 120km/h designed speed. If the expressway is not built a major link connecting regional economic development with the national highway network will be missing. “Do nothing” is not an option. B. Structures

1. Bridges or Tunnels

736. The large river crossings were studied for the alternative alignments. The first possible choice is the type of crossing. The road could either run below the rivers in tunnels or above the river by a bridge. Each of the two types of crossing were studied carefully for each alignment.

2. Types of Tunnels

737. Two types of tunnels were considered : The immersed tube tunnelling method (IMT) and the tunnel boring machine (TBM) method. The immersed-tube, or sunken-tube, method, used principally for underwater crossings, involves prefabricating long tube sections, floating them to the site, sinking each in a previously dredged trench, and then covering with backfill. 738. Tunnel boring machines (TBM) are used as an alternative to drilling and blasting (D&B) methods in rock and conventional 'hand mining' in soil. A TBM has the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in heavily urbanized areas. The major disadvantage is the upfront cost. TBMs are expensive to construct, difficult to transport and require significant infrastructure. A TBM is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through hard rock, sand, and almost anything in between. This could be one of the first times used in Vietnam.

245

739. The Immersed Tube Tunnels cost much less than the Tunnel Boring Machine type. This eliminated the TBM type from further consideration. The cost of IMT tunnels was then compared with the cost of bridges. Feasible alignments for tunnels do exist, however these would involve passing under land adjacent to land used for storage of petroleum products and unloading jetties. Obtaining agreement for such an alignment would be difficult. There are also safety concerns for the fire risk in a tunnel, as well as risks during construction of an immersed tunnel in a busy shipping area. Consequently bridges were selected.

3. Types of Bridge

740. There are three main types of bridge:

(i) Cable-stayed bridge (ii) Suspension bridges (iii) Cantilever bridge

741. A cable-stayed bridge is a bridge that consists of one or more columns (normally referred to as towers or pylons) with cables supporting the bridge deck. Suspension bridges generally require more cable than a cable-stayed bridge. A full cantilever bridge would require even more material and be substantially heavier. A cantilever bridge also has a more noticeable impact on water turbidity than either the suspension bridge or a cable-stayed bridge. 742. Cable-stayed bridges are considered economically more feasible; aesthetically more pleasing; and easier to construct than either cantilever or suspension bridges. On environmental grounds, especially in relation to water resource issues there are clear environmental advantages in constructing cable-stayed bridges. Cable-stayed bridges have been selected for this Project. C. Alternative Alignments

743. There were a total of three alternative alignments considered. Along with these three alignments there were also the two alignments considered in the JETRO Study and the Pre-Feasibility Study. These were :

(i) Alternative FS: which crosses the Soai Rap River between the 220 kV and the 500 kV power-lines approximately 110-metres south of the all the power-lines and runs between them until South of Binh Khanh Commune and it emerges south of the these power-lines then crossing the Long Tau River and entering Dong Nai Province.

(ii) Alternative JETRO: which crosses the Soai Rap River again between the 220 kV and the 500 kV power-lines approximately 110-metres south of the all the power-lines and runs between them and overlaps these powerlines near Binh Khanh Commune and then crossing the Long Tau River north of the Pre FS Alignment and entering Dongnai Province.

(iii) Alternative 1: which crosses the Soai Rap River approximately 110-metres south of the all the power-lines and runs parallel with the power lines within Can Gio District of Ho Chi Minh City South of Binh Khanh Commune then crossing the Long Tau River and entering Dong Nai province very near the Pre-FS Alignment.

(iv) Alternative 2: enters Phu Xuan Commune of Nha Be District of Ho Chi Minh City and crosses the Nha be River.

246

(v) Alternative 3: enters Phu Xuan Commune of Nha Be District of Ho Chi Minh City but runs North of Alignment 2 to avoid a temple then and crosses the Nha Be River (see Figure 4, Chapter I).

D. Description of Project Alignments

1. Alignment in Long An Province

744. The alignment runs through Long An province from Km 0 – Km 10. The starting point is located in Ben Luc District on the HCMC-Trung Luong expressway and connects to RR No.3. From here the alignment goes to the South-East direction and crosses National Highway (NH)1A at Km 3+400 where there are the least number of houses on the both sides of the alignment (at Km1923+700 on NH1A). From Km 4 to Km 10, the alignment goes parallel with the administrative boundary between Binh chanh and Can Giuoc Districts. At Km 6 the alignment was adjusted to avoid the resettlement area that is under construction by the Five Stars International JSC (50m away from the right side of the alignment). The alignment has been agreed by Longan PC (letter No. 5414/UBND-CN dated 3rd November 2006).

2. Alignment in Ho Chi Minh City

745. In HCMC the alignment runs through Binh Chanh, Nha Be and Can Gio districts from Km 2+200 to Km 30+500. At Binh Chanh district: from Km 2+200 to Km 17+100 the alignment goes across Binh Chanh, Tan Quy Tay, Hung Long and Da Phuoc communes. The alignment was modified to avoid the Da Phuoc Waste Treatment Complex as requested by PC of HCMC (Letter No. 8197/UBND-DT dated 16th December 2005). The alignment is in accordance with the landuse master plan of Binh Chanh District.

3. River Crossings

746. The FS and JETRO alignment (dark blue & purple lines in Figure IV.4) did not have an accurate map of the location of the OTL and so proposed a location too close to them. They went between the overhead transmissions at the Binh Khanh Bridge location, north of the 500 KV OTL and south of the 200 KV one. There is not enough room to build the bridge safely. 747. At Nha Be and Can Gio districts the consultants have studied three alternative river crossing locations to avoid the OTL and keep away from Binh Khanh Town and a new port development near the Phouc Khanh Bridge on the Dong Nai side.

a. Alternative 1 (South Alignment)

748. To overcome the disadvantages of the previous alignment studied by TEDIS and JETRO, and avoid conflict with the water pipelines in Cangio area, avoid affecting the 500KV and 220KV electric transmission lines, Phu Huu 1 port and the existing dense residential area at Nguyen Van Tao street, the alignment runs on the right side and 120m away from the existing 500KV transmission line. There is an overlap of about 20m-30m of a project proposed by Vietnam Maritime Administration (from Km 22 to Km 23). However its master plan can be adjusted (Letter No. 517/UBND-PCT dated 16/6/2009 of People’s Committee of Nha Be District).

i. Advantages

749. This Alternative has the following advantages

(i) In accordance with HCMC master plan up to 2020 approved by the Prime Minister at the Decision No.101/QD-TTg dated 22 Jan. 2007.

(ii) The alternative has been agreed by the ADB TA 7155-VIE,, MOT and HCMC Department of Transport as per the Notice No. 301/TB-BGTVT dated 30/6/2009 of MOT and Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC Department of Transport.

(iii) In accordance with comments from HCMC People’s Committee in the letter No. 207/TB-VP dated 11 April 2006.

(iv) Avoids running between 500KV and 220KV transmission lines, which is very dangerous during construction as well as operation of bridges.

(v) Avoids the Phu Huu 1 Port as requested by Dong Nai People’s Committee at the Letter No. 8156/TTr-UBND dated 01 Oct. 2008.

(vi) Does not impact on the master plan of Nha Be Area (vii) In accordance with the development master plan of HCMC. (viii) It is agreed by the Can Gio district PC in the Letter N622/UBND dated 10 June

2009 and the Can Gio Protected Mangrove Forest Management Board (in the letter N126/CV dated 29 July 2009).

(ix) ii. Disadvantages

750. The Alternative 1 has the following disadvantages

(i) There are two long high bridges with navigation clearance (about 250x55m). (ii) At weak soil area. (iii) The overhead transmission lines are visible from the bridge which does not

present an attractive vista

b. Alternative 2 (North Alignment)

751. To avoid the disadvantages of alternative 1, alternative 2 runs to the North of alternative I crossing through Nhon Duc – Phuoc Kieng urban area (Km 20+800-Km 21+100), crossing the Muong Chuoi river at Km 21+500 and running overlaid to an internal road and Phu Xuan residential area (Km 21+900-Km 22+700), going in between Techim Petrolimex and Saigon Metrolimex Store. However, the alignment of alternative II was not agreed by DOT of HCMC of Nha Be district (as stated in the letter No. 517/UBND-PCT dated 16/6/2009 of Nha Be PC and the Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC DOT). 752. This Alternatives has the following advantages and disadvantages

i. Advantages

(i) Construction site is easier than alternative I. (ii) Horizontal alignment is smooth (iii) Only one long high bridge with navigation clearance required (about 300x55) at

the Nha Be river.

ii. Disadvantages

(i) The alignment runs through Nhon Duc – Phuoc Kieng urban area (which has

been approved by HCM PC). (ii) May affect the future Phu Dong port. (iii) At weak soil area. (iv) Runs under the 500KV and 220KV transmission lines.

248

(v) Affects many houses at the existing residential area (particularly at Huynh Tan Phat street).

(vi) Affects Phap Vo Pagoda (25m away from left side of the centerline).

c. Alternative 3 (North alignment)

753. To avoid the disadvantages of the above two alternatives, alternative 3 runs to the North of alternative I crossing through Nhon Duc – Phuoc Kieng urban area (Km20+800-Km21+100), crossing the Muong Chuoi river at Km21+500 and running avoided Phu Xuan residential area (Km22+00-km23+300), avoiding Phap Vo Pagoda, then going through Saigon Petrolimex Port. 754. However, the alignment of alternative III was not agreed to by DOT of HCMC PC of Nhabe district (the letter No. 517/UBND-PCT dated 16/6/2009 of Nha Be PC and the Notice No. 270/TB-SGTVT dated 09/6/2009 of HCMC' DOT). 755. The Alternative 3 has the following advantages and disadvantages.

i. Advantages

(i) Construction site is easier than alternative 1. (ii) Horizontal alignment is smooth. (iii) Crossing at the narrowest location of the Soai Rap river (perpendicular with river)

so has the shortest crossing of the three alternatives.

ii. Disadvantages

(i) The alignment runs through Nhon Duc – Phuoc Kieng urban area, which has

been approved by PC of HCMC. (ii) May affect the Master Plan of Port system at the other side of the river. (iii) At weak soil area. (iv) Affects many houses (particularly at Huynh Tan Phat street). (v) Affects Saigon Petrolimex port. (vi) Is not accepted by DOT of HCMC and PC of Nha Be district

756. Comparison of Project Alignment Options at River Crossing Section is given in Table 3 (Chapter I).

4. Alignment in Dong Nai Province

757. In Dong Nai province the alignment runs through Nhont Trach district (Km 30+500- Km 53+100) and Long Thanh district (Km 53+100-Km 58+500). The alignment avoids Phuhuu I port at Km 30+750 (as requested by Dong Nai PC) and running in parallel with the left side of 500 KV transmission line (away 130 m from the 500KV), crossing 500 KV and 220 KV at Km 32+000. From Km 32+000– Km 52+500 the alignment runs in between the right side of 110 KV and Nhon Trach outer road in accordance with Nhon Trach Master Plan as approved by the Prime Minister. The alignment avoids the Phuoc An port from Km 49+500-Km 52+500, crosses Thivai river at Km 53+100, crosses NH51 at Km 57+500 and connects to future Bienhoa-Vungtau expressway by an interchange. 758. There are four tentative interchanges in Dong Nai province at: Inter-ports road (about km33), NhonTrach city road, National Highway No.51, Bienhoa-Vungtau Expressway. Total length in Dong Nai Province is about 28km.

249

5. Horizontal Alignment

759. The horizontal alignment was designed based on the Alignment 1 selected and agreed to by all the relevant authorities of Long An province, Ho Chi Minh City, Dong Nai province and by the Ministry of Transport. E. Agreed Alignment

760. The Consultants presented the alignment to DOT of HCMC at the meeting on 03/June/2009 with the participants of the city agencies and departments and PCs of Binh Chanh, Nha be and Can Gio districts. Due to lowest negative impacts on local socio – economy of the alignment alternative 1, the meeting has agreed to select this alternative of total length in HCMC 26 km as per the Notice No. 270/TB-SGTVT dated 09th June 2009. In general, the selected alignment of the project was approved by MOT and People’s Committee (PC) of HCMC, Long An and Dong Nai provinces.

PC and the FFC of Binh Chanh commune fully support the project. The expressway crossing over Binh Chanh commune will contribute to create a perfect traffic network of the region as well as the rural roads in the commune. It will help streamline the traffic flow over the commune, thereby assist for local socio-economy. Nevertheless, the expressway will certainly cause direct and indirect impacts on local people

f C f

254

instance: traffic safety, social security and discipline. The PC and the FFC of Binh Chanh commune requests the investor and governmental authorities to cooperate for implementation of the project in compliance with applicable regulations, and to take concrete measures for management of motorized vehicles and trucks, for traffic safety in order to avoid of traffic accidents. At the same time, during the taking of steps of the project, the investor and functional agencies should actively and directly cooperate with authorities in order to prevent bad psychological impacts on local people who are affected by the expressway. The section of Ben Luc – Long Thanh expressway that will cross over Binh Chanh commune. As such, local people will suffer great environmental impacts. The PC and the FFC of Binh Chanh commune basically agree with the environmental impact assessment as well as the mitigation measures specified in the executive summary. Nevertheless, some environmental impacts should be more concerned: When construction activities are carried out, from leveling, digging, building of basement, etc. people living near by the construction sites will be strongly affected by dust, particularly dust from machines and trucks. Besides, there are 83 houses in the impacting scope of the project, not to say many others in the distance of 200m from the expressway. As such, environmental impacts will strongly affect great number of households.

The project EMP requires contractors to implement effective measures for pollution control and implement compensation for damage of houses, public works, economic facilities following the laws and regulations. Grievance Redress Mechanism is prepared for this project will be applide.

The construction will cause water logging, affecting cultivation and aquaculture, etc. That will greatly affect the family economy of households. In addition, an amount of sanitary waste and chemicals from construction materials will directly affect inhabitants. Therefore, in order to mitigate those impacts, the PC and the FFC of Binh Chanh commune request the contractors to use, enclosing dikes or the like to prevent wastewater from overflowing or

B. Public Consultation following the ADB Guidelines

1. Process of Public Consultation with PAHs Following the ADB Guideline

765. Public consultation following the ADB Guideline has been implemented by the EIA Team in 2 rounds:

(i) Round 1: meeting and interviewing 50 PAHs (by random selection) at 7 districts during EIA study (in August 2009) to obtain information on their actual living condition and their suggestions on project’s impacts.

(ii) Round 2: organizing 6 meetings with 497 PAHs at 6 representative communes after preparation of a Draft EIA report (in September and October 2009) to disclose information on the environmental impacts and mitigation measures and to obtain their comments/suggestions

268

2. Preliminary Evaluation on the Present Socio-Economic Conditions of 50 PAHs in the First Round of Public Consultation and Their comment on Project Environmental Impacts

766. To obtain preliminary information on the present socio-economic conditions of the project affected households (PAHs) the EIA Team has conducted interview with 50 households in 7 districts at the Project area: Ben Luc, Can Giuoc (Long An province), Binh Chanh, Nha Be, Can Gio (Ho Chi Minh City), Nhon Trach, Long Thanh (Dong Nai province. The obtained results from the filled questionnaires were synthesized and assessed as follows:

a. Interviewers’ Information

767. Through survey on 50 representative PAHs in the affected area of the project, there are 63.33% of male, 36.67% of female. All of them belong to the ethnic majority of Kinh. There are a variety of religion component including Buddhism (46.67%), Cao Dai Religion (16.67%), other religions accounting for 36.67%.

b. Education Level

768. In 50 PAHs there are 194 people, 7.73% of them at university education level or post - university level, 9.28% of them at college level, 28.35% of them at grade 10-12 level. 65% of them at grade 6 - 9, 22.68% under grade 6 and 10.31% of them illiterate. The collected information shows that education level in different regions greatly differs so that land acquisition and compensation need to be handled carefully and have meticulous recorded paperwork for households having a low education level.

c. Main Income

769. The main income of the interviewed households at the Project communes is as follows:

(i) Aquaculture: 17% (ii) Trading: 35% (iii) Office staff: 24% (iv) Animal husbandry: 12% (v) Gardening: 12% (vi) Forestry: 0%

770. Through the socio-economic conditions collected from 50 typical households affected by the project, the number of households with main income from salary and business is much more than that from aquaculture, animal husbandry and gardening. According to the survey’s results, although at Ben Luc, Can Giuoc, Binh Chanh and Nhon Trach districts have a quite large areas of rice cultivation, most of output is used for households and animal raising. 771. Monthly average income of 50 households interviewed have 6.67% of 1-2 million/month; 16.67% of 2-3million/month; 26.67% of 3-5 million/month; 30.00% of 5-10 million/month of and 20.00% of 10 million/month and none under 1 million/month. The survey results show that main income of households is higher than and more stable some other districts in the Mekong Delta Region.

d. Requirements in Future Employment

772. There are 53.33% of interviewees keep working their job at present (mainly businessman and workers) and 46.67% do not know what they will work as after land loss for the project (almost all households using land as rice planting, gardening, animal raising and aquaculture)

269

e. Environmental Sanitation

i. Water Supply

773. Some of 50 households interviewed use rain-water and well-water as main water supply sources, some use drilled well-water and tap-water. According to survey’s results, 51.28% of households use rain-water source, 15.38% of them use rain-water source, 25.64 of them use tap-water source and 7.69% of them use dug-well water source. Almost all households in Nha Be and Can Gio use tap-water with price about VND 50,000/m3 (of over 20 times higher than the average price of clean water in the urban area). Groundwater cannot be used for households in Can Gio, whereas in Nha Be water from drilled-well water can be used for bathing and washing mainly, water for cooking and drinking is from water-tap or water supply tankers. Concerning water quality in 50 households interviewed, 36.67% of them think that water source is good, 43.33% of them think that it is medium, 3.33% of them think that it is bad and the rest (16.67%) have no comments.

ii. Waste Collection, Disposal and Treatment

774. There are 43.33% of households who said that wastes are collected and treated by collecting system of commune or company; 30.00% of them bury waste; 26.67% of them collect waste and burn. At the crowded population site including Binh Chanh, Nha Be, Long Thanh and a part of Can Gio, there is collecting waste system. At the remaining districts in thinly populated sites, most wastes are collected and treated at households by digging holes to bury making fertilizers for gardening, or by burning.

iii. Sewage Drainage System

775. In 50 households interviewed 23.33% of them have public drainage water system of commune; 33.33% of them discharges waste water in canal system, the rest of them let waste water overflow and absorb by soil (43.33%). Almost all areas that the alignment will pass do not have a sewage drainage system, accept for some area close to Highways 1 and 51 or some dense population sites.

i. Requirements of PAHs in Environmental Management of the Project

776. According to the results from interview on the representative PAHs the project owner is required to have effective measures in environment protection, particularly dust, noise and vibration mitigation during the project construction activities. The project should ensure a good drainage system, not make difficulties for people in daily life and production, be good at labour resource management that does not affect to public security and spiritual life of the local people. Moreover, the PAHs require that the policies on land acquisition and compensation should be reasonable and the investors should create policies on employment, using local labour resource.

3. Comments of 497 PAHs in the Second Round of Public Consultation

777. After completion of a Draft EIA for the Project, from 16 September to 16 October 2009 the Environmental Consultant in the ADB TA – 7155 – VIE has cooperated with the Social Consultant in consultation with PAHs in 6 typical communes affected by the project.

C. Feedback by the Project Owner to Comments of PCs, FFCs and PAHs

792. The project owner (Vietnam Expressway Corporation) found that comments of the PCs and FFCs of 15 communes and the interviewed PAHs very diverse and correct. Therefore, the project owner accepted the comments and suggestions of the PCs, FFCs and people of 15 communes in the project area. 793. Although requirements of the commune’s PCs, FFCs and PAHs are diverse, but they mainly focus on the following issues:

(i) Proper implementation of RAP policy (ii) Proper control of dust, noise, water pollution during road and bridge construction (iii) Proper manage solid wastes and waste waters from worker camps and

construction sites. (iv) Well organize construction activities to avoid encroachment into residential,

agricultural, aquaculture areas (v) Prevent water inundation, do not fill up canals and drainage system. (vi) Repair the local roads and public facilities (vii) Prevent health accident during road and bridge construction (viii) Proper management of labor force (ix) Strictly follow the Vietnamese Law on Environment, relevant laws and Standards

for Environmental Quality. 794. To meet the requirements of local peoples the project owner will undertake proper measures to prevent and mitigate negative impacts on the environment quality, biological resources and local socio-economy as predicted in this EIA report.

277

795. For the implementation of the Ben Luc – Long Thanh expressway project to reach high economic efficiency and at the same time, to minimize negative environmental impacts, the project owner will properly implement all items in the Environmental Management Plan (EMP) given in this EIA report, approved by MONRE and ADB. The main tasks in environmental management for this project to be well implemented by VEC and its contractors are summarized below.

(i) Select best alignment to minimize encroachment into industrial parks, churches, temples, pagodas, forest areas (especially in the Can Gio Biosphere Reserve) and dense populated areas.

(ii) Implement the site clearance and resettlement plan in compliance with the laws of Viet Nam, policy of ADB to support the PAHs in life restoration and economic improvement as required by local government and people

(iii) Apply management and technological measures to control air pollution, noise, vibration, and pollution of surface water, groundwater and soil due to construction activities.

(iv) Properly protect the aquatic and terrestrial habitats throughout the construction and operation of the expressway.

(v) Well manage the labor force in order to avoid community disturbance and negative social matters

(vi) Well comply with Vietnamese Environmental Standards and Technical Regulations (TCVN, QCVN) for quality of soil, air, surface water, ground water, and noise.

(vii) To bear responsibility to the laws of the Socialist Republic of Viet Nam in case of any occurrence of serious environmental pollution and environmental accidents that severely affect the life and business of people and the natural environment.

VIII GRIEVANCE REDRESS MECHANISM

A. Introduction

1. Definition of Grievance Redress Mechanism

797. According to a paper of Compliance Advisor Ombudsman (CAC), prepared for IFC, June 2008 Grievance Redress Mechanism (GRM) is an institutionalized and organized method consisting of specified roles, rules and procedures for systematically resolving complaints, grievances, disputes or conflicts, GRMs provide a way to reduce risk for projects, provide an effective avenue for expressing concerns and achieving remedies for communities, and promote a mutually constructive relationship. 798. Local people need a trusted way to voice and resolve concerns linked to a development project, and project owners need an effective way to address community concerns. A locally based grievance resolution mechanism provides a promising avenue by offering a reliable structure and set of approaches where local people and the project owner can find effective solutions together. 799. A well-functioning grievance mechanism includes the following requirements.

(i) Provides a predictable, transparent, and credible process to all parties, resulting in outcomes that are seen as fair, effective, and lasting

(ii) Builds trust as an integral component of broader community relations activities (iii) Enables more systematic identification of emerging issues and trends, facilitating

corrective action and preemptive engagement.

2. Principles of Good GRMs (according to CAC)

800. Problems are often resolved more easily, cheaply, and efficiently when they are dealt with early and locally. The experience and research indicate that there is a core set of practices that mark effective, credible company (project owner or its contractor) − community grievance mechanisms. 801. The followings are some principles of effective grievance resolution systems in resolution of complaints in adverse social impacts as well as environmental impacts. 802. Refine core company values. To improve their community relations in general and grievance resolution in particular, companies can adopt certain critical values or attitudes. These include:

(i) Commitment to fairness in both process and outcomes. (ii) Freedom from reprisal for all involved parties within the company and in the

community. (iii) Dedication to building broad internal support for the grievance mechanism across

project lines. (iv) Mainstreaming responsibility for addressing grievances throughout the project,

rather than isolating it within a single department. (v) Willingness by senior management to visibly and sincerely champion the

grievance system.

284

803. Start early in the project cycle. The most successful grievance mechanisms are put in place as early as possible ideally, during the project feasibility phase and are modified for later project phases. Problems are often resolved more easily, cheaply, and efficiently when they are dealt with early and locally. 804. Involve the community. Stakeholders (in Vietnam they are local administrative agencies, environmental management agencies, social organizations, environmentalists, scientists, legal agencies etc…) from the community and company should be involved in the grievance mechanism. 805. Ensure accessibility. An effective grievance mechanism should be accessible to diverse members of the community. Multiple points of entry, including face-to-face meetings, written complaints, or e-mail, should be available. Opportunities for confidentiality and privacy for complainants should be honored where this is seen as important. 806. Maintain a wide scope of issues. The grievance mechanism should be open to a wide range of concerns: both those based in factual data and those arising from perceptions or misperceptions. Perceived concerns can be as critical to address as actual hazards. The mechanism should also be able to address multiparty and multi-issue complaints. 807. Develop culturally appropriate procedures. The mechanism should be responsive, respectful, and predictable clearly laying out an expected timetable for key process milestones. The grievance mechanism should be capable of bridging deep divides, including cultural divides. The design and operation of the grievance mechanism should consider cultural differences, such as communities’ preferences for direct or indirect negotiation; attitudes toward competition, cooperation, and conflict; the desire to preserve relationships among complainants; authority, social rank, and status; ways of understanding and interpreting the world; concepts of time management; attitudes toward third parties; and the broader social and institutional environment. 808. Incorporate a variety of grievance resolution approaches. To accommodate differences in personal and cultural preferences, the grievance mechanism should offer a variety of grievance resolution approaches, not just a single grievance procedure. The complainant should have influence over which approach to select. Some complaints may be managed in an informal way solely by those directly involved, such as a company representative and the complainant. Others may rely on more formal independent redress, such as arbitration, using a neutral third party. Some mechanisms may rely on an interest-based approach, such as responding to the stated legitimate and perceived needs of the complainant. Others may rely on a rights - based approach, based on legal, contractual, or other rights. Where possible, local, customary ways of grievance resolution should be evaluated and incorporated into the system. 809. Identify a central point for coordination. A well-publicized and consistently staffed position, held by an individual or team, should be maintained. This central coordinator facilitates the development and implementation of the grievance mechanism, administers some of its resources, monitors internal and external good practice, ensures coordination among access points, and makes certain that the system is responsive to the information it manages. 810. Maintain and publicize multiple access points. Expanding access beyond those individuals who have the primary responsibility to receive grievances can significantly reduce barriers to entering the system and encourage community members to address problems early and constructively. Individuals serving as access points are most effective if they are

285

trustworthy, trained, knowledgeable, and approachable regardless of the ethnicity, gender, or religion of the complainant. 811. Report back to the community. The company should provide regular feedback to relevant stakeholders to clarify expectations about what the mechanism does and does not do; to encourage people to use the mechanism; to present results; and to gather feedback to improve the grievance system. Information reported back might include types of cases and how they were resolved and the way the grievance has influenced company policies, procedures, operations, and the grievance mechanism itself. 812. Use a grievance log to monitor cases and improve the organization. In addition to resolving individual or community disputes, the grievance mechanism is an opportunity to promote improvements in the company. A grievance log (or register) can be used to analyze information about grievance and conflict trends, community issues, and project operations to anticipate the kinds of conflicts they might expect in the future, both to ensure that the grievance mechanism is set up to handle such issues and to propose organizational or operational changes. Sometimes, enacting policies or other types of structural change can resolve grievances around a common issue, rather than continuing to settle individual complaints on a case-by-case basis. 813. Evaluate and improve the system. The company should periodically conduct an internal assessment of the grievance mechanism to evaluate and improve its effectiveness. Important elements of evaluation include general awareness of the mechanism; whether it is used and by whom; the types of issues addressed; the ability of the mechanism to resolve conflicts early and constructively; the actual outcomes (impacts on project operations, management systems, and benefits for communities); its efficiency; and, most fundamentally, the ability to accomplish its stated purpose and goals. At certain times, the company should also solicit and include the views of stakeholder representatives to see how the mechanism is proving effective in practice. A good grievance mechanism should be simple to understand but not simplistic in its dealings with people and issues. Clarity and a user - friendly approach are certain to yield positive results. B. Proposed Grievance Redress Mechanism (Environmental) for the Project

1. Identification of Stakeholders in GRM for this Project

814. This GRM identifies the following stakeholders : .

(i) Community includes people of different groups who may be positively or negatively affected by the project during the pre-construction, construction and operation stages.

(ii) Project affected people (PAPs): people who may be negatively affected by environmental impacts generated by the project activities in the pre–construction, construction and operation stages.

(iii) Complainant: an individual or group of people with an issue, concern, problem, complaint or claim that he, she or they want addressed and/or resolved (in the field of environmental impacts).

(iv) Governmental authorities: governmental agencies responsible in state management on natural resources, environment, security and justice in the project’ provinces or at the central level. In this project, relevant agencies in resolution of grievances in environmental performance include: a) People

286

Committees (PCs) of communes, districts and provinces/city in Ho Chi Minh City, Long An and Dong Nai provinces. b) Functional agencies of the PCs at commune’s level: Section of Economy – Natural Resources and Environment; Section of Agriculture - Forestry-Fishery; Section of Security, Resettlement Teams, etc. c) Functional agencies of the PCs at district level: Division of Natural Resources and Environment ; Division of Economy; District’s Police; Division of Agriculture - Forestry – Fishery, Division of Labor – Invalid and Society; District’s Resettlement Committees; d) Functional agencies of Province’s PCs: Departments of Natural Resources and Environment (DONRE); Justice (DOJ), Agriculture and Rural Development (DARD), Labor - Invalid and Social Affairs (DOLISA); Environmental Police’s Divisions of Departments of Public Security, Department of Planning and Investment (DPI); e) Relevant ministries: Natural Resources and Environment (MONRE), Transport (MOT), Justice (MOJ), Labor- Invalids and Social Affairs (MOLISA) and Planning and Investment (MPI).

(v) Social - Political Organizations: Public organization in all communes, districts in the project area. The most relevant to this project are: Fatherland Front Committees (FFCs), included Women Associations, Veterans Associations, Youth Associations, Associations of Farmers.

(vi) Social Professional Organizations: include non-government organizations (NGOs) at all project’ provinces. The most relevant for this project are Vietnam Union of the Sciences and Technology Associations (VUSTA), Vietnam Association for Conservation of Nature and Environment (VACNE), Vietnam Association for Environmental Impact Assessment (VAFEIA), Vietnam Association of Biology, and Vietnam Association of Construction etc.

(vii) Project Owner: in this project this is the Vietnam Expressway Corporation (VEC) and/or its representative: the Project Implementation Unit 3 (PIU3) who is responsible in management of this project.

(viii) Contractor: a unit who have signed a contract with VEC or PIU3 to implement any part of the project in the pre - and construction stages.

(ix) Third party: one or some governmental units or independent units who have functions to evaluate damages caused by the project to the PAHs and it is invited by the complainants or local PCs/local socio-political associations to resolve the claims in cases that the project owner or contractors and complainants can not resolve the grievances. In this project the third party may be the local Meditative Committee (Ban Hoa Giai in Vietnamese) (first step) or local and central courts (final step).

2. Legal Guidelines of Vietnam on Grievance Redress in the Environmental

Field

815. Chapter XIV in the Law on Environmental Protection (LEP) passed by the National Assembly on 29 November 2005 gives detailed guidelines in inspection, resolution of grievances in cases of environmental damages or risks caused by projects or companies. Some clauses related to directly to grievance redress in the environmental field are listed below. 816. Clause 127 regulates that:

(i) Individual/company, caused environmental pollution or damage for communities, should compensate and restore the environment following the LEP and other relevant laws.

287

(ii) Head of organization/company, governmental officers, who shielded violation of the LEP, causing environmental pollution or damage, should be punished and be responsible for compensation according to the relevant laws.

817. Clause 128 gives the following general guidelines on grievance redress mechanism:

(i) Organization/ individual has right to complain to governmental authorities or to courts on any actions violating the LEP and/or affecting its/his/her or their legal rights or benefits.

(ii) Citizens have rights to accuse to governmental authorities in the following actions violating the LEP: a) Actions causing environmental pollution, degradation or environmental risks; b) Actions violating rights and/or benefits of the State, communities, citizens, organizations and individuals.

(iii) Government agencies receiving complaints or accusing letters/petitions should be responsible for review and resolution according to the legal guidelines on grievance and complaints and the LEP.

3. ADB Requirements in Grievance Redress Mechanism

818. In Appendix 1 of the ADB Safeguard Statement (2009) the requirements in GRM are as follows. “The borrower/client will establish a mechanism to receive and facilitate resolution of affected peoples’ concern, complaints, and grievances about the project’s environmental performance. The grievance mechanism should be scaled to the risks and adverse impacts of the project. It should address affected people’s concerns and complaints promptly, using an understandable and transparent process that is gender responsive, culturally appropriate, and readily accessible to all segments of the affected people at no costs and without retribution. The mechanism should not impede access to the country’s judicial or administrative remedies. The affected people will be appropriately informed about the mechanism”.

4. Project’s Potential Environmental Impacts and Types of Grievances the Project Owner/Contractors Typically Encounter

819. Information from Chapter V and lessons from various road development projects in Vietnam indicate that in 3 stages of the Ben Luc – Long Thanh Expressway Project various adverse impacts will be generated but only the medium or major impacts will be claimed. The most common potential impacts and correlative types of grievances that the project owner (VEC or its PIU3) and/or its contractors will encounter, are indicated in Table VIII.1. Table VIII.1: Typical Impacts and Types of Grievances in the 3 Stages of the Ben Luc –

This type of claim, concern, and complaint will arise in cases that the project or local Resettlement Committees will not properly implement the compensation and support policies.

288

population of people

2 Resettlement ditto ditto ditto 3 Site

clearance - Minor or medium or major claim that the project activities in site clearance have caused adverse impacts on public facilities, cultural sites, economic facilities. - From lessons of other similar projects impacts on mangrove trees or mangrove forests are not reason of claim or grievance, due to people not being well aware of their importance.

- Some PAHs. -A group of PAHs. - Some companies -Local governmental agencies.

This type of concerns, claims, grievances may arise in the following cases: - Encroachment or disposal of wastes into cultivation, aquaculture areas outside the project ROW. - Encroachment into business areas outside the project ROW - Encroachment into public technical facilities, cultural, religious sites

In the Construction Stage 4 Noise

pollution caused by road/bridge construction and material transport

Medium claim - Some families - Local PCs or local social - political organizations.

- Trucks moving at dense populated area generate big noise. - Operation of strong noise generators (constructions machines makes big noise).

5 Canal or aquaculture water pollution caused by storm and waste water from construction sites

Medium claim Ditto Discharge of waster water or polluted storm waters from construction sites to shrimp ponds or canals that may kill shrimps, fish affect water supply or tourism activity.

6 Land pollution caused by disposal of wastes

Minor or medium claim

Ditto Disposal of solid wastes and/or waste waters from construction site/ worker camps, caused land pollution, affecting on food crops and landscape etc.

7 Damage of houses,


Ditto This type of claim will arise when houses, roads and

289

roads or local infrastructural facilities, caused by road, bridge construction

public works will be damaged by construction activities.

8 Filling canals, local water drainage systems

Medium or major claim

Ditto This type of grievance may arise when the contractors fill canals or drainage channels of dispose solid wastes obstructing drainage systems of local residents.

9 Obstruction of waterway transport caused by bridge construction

Minor claim - Waterway transport companies, - Inland waterway Police.

This type of claim may be risen when operation of barges transported materials for bridge construction or floating cranes will obstruct the normal movement of ships, boats

10 Air (dust) pollution caused by earth works and transport of materials

Medium or major claim

- Some families - Group of families - Local PCs or Socio-Political associations - Some companies, affected by air pollution.

This type of grievances is common at various road construction projects in Vietnam. Claim will be arise when dust pollution is seriously affecting normal business and life of local residents.

11 Land slide, soil erosion, caused damage for cultivation field, aquaculture ponds, local landscape


- Some families - Local PCs or local socio-political associations - Some companies.

This type of grievances may arise when soil erosion or land slice may cause significant damage for rice fields, fish/ shrimp ponds local canals or roads.

In the Operation Stage 12 Traffic

accidents Minor - Local PCs Accident would be big

problem but complaint about this problem is rarely given, because reasons for traffic accidents are commonly caused by drivers not from the project owner.

13 Noise pollution, generated by traffic activity

Minor - Local PCs In Vietnam so far, this type of grievance is not common, although at many places noise levels caused by traffic operation exceed the standard. Most households can live closely to the roads where noise pollution is evident but do not like to have a noise control wall in front of their houses.

14 Environmenta risks (fire, explosion)

Minor Local PCs This type of grievances did not occur in Vietnam

5. Mechanism of Grievance Redress Applied for this Project

a. Legal Guidelines on Compensation for Damages Caused by Environmental Impacts

820. The LEP (2005) regulates scope and mechanism for compensation and resolution of damages in the environmental field with the following clauses. 821. Clause 130 gives identification of damages caused by environmental pollution and degradation which affected people can complain:

(i) Degradation of functions and useful properties of the environment. (ii) Damages of health, life of people and legal profits of organizations/individuals

caused by environmental degradation. 822. Clause 131 regulates on determination of damages/loss caused by environmental pollution or degradation:

(i) Loss of environmental functions and useful properties is divided into 3 following levels: a) Slight degradation; b) Serious degradation; c) Very serious degradation.

(ii) Determination of areas, limits of degraded environment include: a) determination of limit and area of the serious and very serious impacted core zone; b) determination of limit and area of the directly affected buffer zones; c) determination of other zones affected by the impacts from the core zone and buffer zones.

(iii) Determination of degraded environmental components includes: a) Determination of number of the degraded environmental components, types of ecosystems and affected species; b) Damage levels of each environmental component, ecosystem and species.

(iv) Calculation of environmental damages is regulated as follows: a) Calculation of direct and long-term damage due to environmental degradation; b) Calculation of expenditures for environmental restoration; c) Calculation of budget for mitigation or deletion of the pollution sources; d) Public consultation in resolution.

(v) Determination of environmental damages is implemented independently or in cooperation of project owners and affected sides.

(vi) In cases that project owners or affected sides require the functional agencies in environmental protection should have responsibility to give guideline for calculation.

823. Clause 132 regulates appraisal of environmental damage or functional degradation with the following requirements:

(i) Appraisal of environmental damages or useful properties of the environment is implemented according to requests of complainants or agencies responsible for grievance resolution

291

(ii) Basis of appraisal of environmental damages are: letters of complainants, information, document, evidences related to damage compensation.

(iii) Selection of appraising body should be mutually agreed by the compensating side and complaining side. In case no mutual agreement of 2 sides the agency responsible for resolution of grievance will decide.

824. Clause 133 guides resolution in complaint on environmental damages with the following three options:

(i) Self – negotiation between related sides. (ii) Request arbitrator to resolve. (iii) Request court to resolve.

825. The above legal guidelines on compensation of environmental damages indicate that in the Ben Luc – Long Thanh Expressway Project as well all the projects in Vietnam all adverse impacts caused by project activities, damaging the environmental quality or natural resources, affecting their properties or life of local residents may be claimed by the affected individual or organizations and the project owners or their contractors should have responsibilities in compensation for the damages and restoration of the degraded components of the environment. Mechanism of grievance redress is regulated in the clauses of the LEP (2005).

b. Steps in Grievance Redress Related to Environmental Impacts for the Ben Luc – Long Thanh Expressway Project

826. To make local residents clearly understand and easily follow the legal regulations in grievance resolution on environmental performance a process of 6 (six) steps in Grievance Redress Mechanism for this project is proposed below.

i. Prepare a Complaint

827. Based on the above legal guideline any individual, household or organization (business unit, production unit, governmental or private office socio-political association etc…) or commune/district PCs can make a claim against the project owner or its contractors, if her/his or their properties/ life/ business/health or public environment will be damaged by project activities. Their claims may concern all evident adverse impacts : small, medium impacts (noise or dust pollution) to major impacts (massive shrimp death caused by waste water from construction site or strong vibration caused by pile drivers making house collapse or inundation, caused by filling drainage channel etc.). 828. In cases where complainants are individuals/households companies or NGOs claim can be performed by various ways:

(i) Verbal: direct express their complaint to representatives of the contractor or project owner in a face to face meeting. Witness of village representatives and neighbors of the complainant is important in verbal conversations.

(ii) Written form: express their complaint to contractor of project owner (VEC or PIU3) in a written form. In this case witness and confirmation of neighbors of the complainant and representatives of commune’s PC or FFC is not compulsory but important for further resolution of VEC/PIU3 or its contractors

292

(iii) Use public media: the complainant can provide evidence of impact caused by the project activities to a local or central newspaper or TV to ask the media supporting her/him/them in resolution.

829. In cases of complainants are commune’s or district’s PCs claim can be performed by following ways:

(i) Written form: express complaints to contractor or the project owner in written form, included evidences (data, photos etc.) of the damaged caused project activities.

This document should be signed by PCs authorities and sent to the contractor, project owner and a copy of the document should be sent to the higher administrative agency (e.g. commune’s PC should send a copy of its complaint to district’s PC).

(ii) Use public media if it is necessary. 830. To obtain proper and fast resolution in all types of preparation of complaints the complainant (individual/household, company, NGO) should:

(i) Ask local village / commune officers (PC or Police) to prepare Minutes of Record of evidence of damages caused by the impacts of project activities and with signature of representatives of 3 sides: the project owner or contractor who directly making this damage, complainant and local PC or FFC or witnesses.

(ii) In principle, the measure may be used in any case, but it is better in the case of failure in self–resolution between the complaint and representatives of project owner/contractor.

831. The complainant can directly express her/him/their claims to representative of the contractor/project owner (in case of verbal complaint) or send her/his/their grievance letter to offices of project owner/contractor and with a copy to local commune PC (in case of grievance in written form). If the complainant does not know how to send a complaining letter he/she can ask local PC or a media company help them to send this letter to the contractor/project owner.

ii. Receive and Register a Complaint

832. Once a complaint has been received, it should be registered by the project owner/contractor and local PC. Within maximum 15 calendar days a reply in written form from the project owner/contractor should be sent back to the complainant with a copy to the local PC. In this reply letter includes the main following information:

(i) Registration of the project owner/constructor on the complaint (ii) Proposal of project owner/contractor on methods applied for assessment of the

damages. (iii) Schedule of damage assessment, negotiation and resolution.

iii. Screen for Eligibility and Assess the Complaint

833. This steps to be done by the project owner/contractor are to:

(i) Determine whether a complaint is eligible (if it is due to the project) or ineligible (if it is not project - related). This step is important as in some cases the reasons of the claim may not related to the project (for example, in the case of claim about

293

loss of shrimp culture: in fact, shrimps may be massively died by bacteria contamination but not by run-off water from the construction site, due to this phenomenon is also happen at the shrimp farms where do not receive run-off water from the project site).

(ii) To clearly determine validity of the complaint the project owner/contractor should invite a third party such as District/commune’s PCs, DONRE or other organization to be involved.

(iii) In case the complaint is found not to be related to the project, the project owner/contractor should clearly explain to the complainant. If the complainant will not agree with the explanation he/she may ask local PC to find a third party (local PC, DONRE or other organization for reassessment.

(iv) Determine who will conduct the assessment of the damages: Depending on the contents of the complaint some agencies may be asked to help the project owner/contractor in assessment of levels of impacts and damages. They may be an environmental monitoring unit or an economic evaluation unit in the project provinces. In cases that assessment of damages are very complicated, for example, strong inundation caused by canal fill, massive die of shrimp, etc. some functional agencies from central level: MONRE, MARD and experienced specialists may be invited. According to the Law on Environmental Protection (2005), assessment unit should be mutually agreed by 2 sides (the complainant and VEC/or its contractor).

834. This step is completed within 30 calendar days from receiving the complaint.

iv. Assess the Damages Caused by the Project Activities

835. In case the complaint is related to the project activities, representatives of the project owner/contractor with the selected assessment unit should visit the complaint and the place where damaged was complained of. The assessment should be implemented with participation of the complainant and witness of representatives of commune’s PC or FFC The results of the assessment should be agreed by the complainant and should be signed by the complainant, representatives of project owner/contractor, assessment unit and communes’ PC. 836. If one side is not satisfied with the assessment results they can propose another method or another assessment unit to re-assess the impacts until the assessment satisfies both sides. In case the complainant requests, the local PC should help her/him/them to find the assessment unit suitable for the case. 837. The step of assess the damages should not be lasted over 45 calendar days from receiving the complaint

v. Select grievance resolution approaches

838. Depending on the contents of the complaint and level of adverse impact in this step the project owner/contractor may select a reasonable way for resolution. Some common ways suitable in the conditions of the project’ provinces are suggested below.

(i) The complainant proposes a solution, based on their self - evaluation of their damages.

(ii) The project owner/contractor proposes a solution, based on the legal regulation and their assessment of the damages.

(iii) The complainant and project owner/contractor negotiate.

294

(iv) Two sides defer to a third party (local mediating committee), governmental agencies with participation of environmental management units. In case of failure in solution proposed by these bodies both sides may request a court to decide.

839. So far, in Vietnam, almost all claims in environmental pollution caused by impacts of the infrastructural projects, included road and bridge construction were resolved by negotiation of the related sides. No case resolved by a court is recorded, excepted for damage in local economy caused by land acquisition and relocation. 840. This step is required to be completed within 60 calendar days from receiving the complaint. After this determined time if this process has not been fully resolved the complainant may send a letter to the project owner / its contractor to require them to speed up the process of resolution. The complainant may also ask local PC to support in enforcing the project owner to speed up the process.

vi. Compensate Damages Caused by the Project Activities and Communicate Back to All Parties Involved

841. After obtaining agreement of the complainant and the representatives of the project owner/contractor in levels of damages relating to environmental impacts of the project and methods of grievance redress, the project owner or its contractor will immediately implement compensation for the complainant. The compensation may be done by money and/or properties provision (land, construction materials, house, apartment etc.), depending on the negotiation between two sides or by decision of courts. Compensation includes also restoration of the damaged environment caused by the project activities, if the complainant required (for example, clean aquaculture ponds, polluted by the project or repair/reconstruct damaged house or road). 842. Compensation for the damaged environment should be resolved as fast as possible but should not take over 90 calendar days from receiving the complaint. Only in some cases where a long time is needed for environmental restoration repairing damaged roads, cleaning aquaculture ponds, mangrove replanting etc. the time for completion of compensation may be longer but must not exceed 365 days. The compensation should be observed by a witness who is a representative of the local communes’ PC. 843. A minute recording the results of this grievance redress should be prepared and signed by the complainant, representatives of the project owner/contractor and local PC. A summary of this minute should be informed to the relevant sides: local PC, complainant, project owner/contractor and media and court (in case of their involvement in the resolution). 844. From resolution of the grievance the project owner/contractor and local PC, socio-political and social associations should obtain lessons, so that faster and better resolutions to can be achieved for other claims if they again arise during project implementation. 845. To properly implement the compensation of damages caused by the environmental impacts created by the Ben Luc – Long Thanh Expressway Project the above suggested Grievance Redress Mechanism should be monitored by the following agencies:

(i) Commune’ PCs where there is a complaint. (ii) Fatherland Front Committee (FFCs) where there is a complaint.

295

846. To get better results in grievance redress monitoring these agencies may invite professional agencies, e.g. the Provincial DONRE and Environmental Police or DOJ (in the complicated cases) to participate in the monitoring plan. 847. In case the complainant is not satisfied with the resolution of the project owner/contractor he/she/they can implement the following measures:

(i) Re-calculate his/her/their loss by project activities; find more evidences of the damages.

(ii) Refer with a third party (mediator, lawyers to find other approach). (iii) Stop complaint if he/she/they aware that his/her/their evidences are not clear or

reasons are not from the project.

vii. Responsibilities of Commune’s or District’s PCs and Public Social Organization in Resolution of Complaints

848. The commune’s and district People Committees (PCs) are administrative agencies responsible for management of all socio-economic sectors in territory of commune and district. The PC can use its sectoral offices (Resettlement Committee, Office of Agriculture – Forestry – Aquaculture; Office of National Resource and Environment; Commune’s police…) in implementation of its responsibilities. 849. In the Grievance Redress Mechanism for Ben Luc – Long Thanh Expressway Project People Committees take the following responsibilities.

(i) Assist the complainant in making a minute of record about the environmental damages caused by the contractor during project activities.

(ii) Receive a copy of grievance letter to contractor/project owner from complainant. (iii) Monitor the process of the project owner in complain resolution. Based on the

Grievance Redress Mechanism proposed for this project. (iv) Assist the complainant to enforce the project owner to speed up the process of

complaint resolution, if this process was not followed the schedule proposed in the Grievance Redress Mechanism.

(v) Involve in screening the validity of the complainant. (vi) Advise the affected persons that his/her complaint was found not related to the

project by the following steps: - Check again to find real reasons caused damages for his/her property. - Support him/her to prepare and to send complaint letter to relevant

agencies, if the reasons were identified. - Support him/her in restoration of living conditions during waiting

for compensation from the companies caused damage. (vii) Act as Witness in compensation process of the project owner/its contractor for

the complainant. (viii) In case of the public environment or public works (e.g. river, canal, land, forest,

roads, water supply system, communication system etc.) will be damages by construction activities the commune’s or district PC will take responsibilities to be a complainant. In this case the PC will implement all legal guidelines and follow the steps of the Grievance Redress Mechanism proposed for this project.

296

850. The Fatherland Front Committee (FFC) is a socio-political organization at commune, district, provincial and central levels. A FFC includes various members – associations such as Farmer Association, Youth Association, Veteran Association. 851. In the Grievance Redress Mechanism for this project the FFC at commune or district has the following responsibilities.

(i) to be a representative of commune/district to complain the project owner /its contractor in case of public works or economic activities of local people damaged by project activities

(ii) Assist in document preparation for individual complaints in process of grievance redress.

(iii) Witness environmental damage assessment, negotiation between the project owner/its contractor and the complainant and in compensation process.

852. Provincial Department and District Division of Natural Resources and Environment (DONREs) may support complaints in assessment of environmental impacts caused by the project activities if it is required by one of 2 sides (complainant and project owner) or by the PC. 853. This may be done by measurement of the loss of fish, shrimp, analysis and evaluation of water pollution (in case of water pollution: generated by storm water from project site) or measurement and analysis of air, noise, vibration pollution caused by construction activities. Data from DONRE in environmental impact assessment may be used by 2 sides: the project owner and the complainant in grievance resolution. 854. Framework for handling complaints involving most relevant sides, included governmental agencies is shown in Figure VIII.1.

297

Figure VIII.1: Steps in GRM for Ben Luc-Long Thanh Expressway Project and participation of stakeholders

855. The time frame for the above procedure is:

(i) Reply to the complainant: within 15 days from receiving the complaint (ii) Assess the damage within 45 days from receiving the complaint (iii) Select grievance resolution approach: within 60 days from receiving the

complaint (iv) Compensation for the damaged environment: within 90 calendar days from

receiving the complaint, except for some specific cases (within 365 days).

Notes: 864. External Experts. Being an environmental category A project, VEC shall engage and retain qualified and experienced external expert(s) to verify, on an annual basis, the monitoring information submitted to ADB. This is required under ADB’s Safeguard Policy Statement 2009. The terms of reference for the external monitoring consultant (EMC) is given in Appendix IX.1. 865. GHGs Monitoring/ GHG Emission Inventory. According to Para. 39, Appendix 1 of the ADB Safeguard Policy Statement (2009), quantification and monitoring of GHG emission annually in accordance with internationally recognized methodilogies is required if a project’ aggregate emissions of direct sources as well as indirect sources such as from electricity purchased for own consumption of the project, is equal to or exceed 100,000 tons of CO2 equivalent per year. 866. Based on the calculation provided in Chapter IV of this EIA report, the 100,000 tons/year threshold will be exceeded. Therefore, a GHG Monitoring Plan through inventory of CO2 emitted annually by traffic activities on the BL-LT expressway is triggred. 867. The data obtained from the GHG inventory can help:

(i) Understand CO2 emission amount and trend of ADB supported projects; (ii) Test and improve the methodology for CO2 quantification and monitoring; (iii) Help the borrower (Government of Viet Nam) and VEC to enhance their

awareness and promote emission reduction. 868. The recommended method for GHG monitoring for the BL-LT expressway is as follows:

(i) Apply ADB’s suggested formula using a simple tool to calculate GHG emission (CO2 load) (see Appendix IX.2) for annual inventory of CO2 emission generated by all vehicles using the the BL-LT expressway.

(ii) To readily apply ADB’s formula, the following table (Table IX.4) shall be used by the project owner (VEC) in calculating annual CO2 emission on the Project expressway.

336

Table IX.4: Simple Tool to Calculate GHG Emissions (CO2 Load) and Threshold Traffic in Terms of Passenger Car Units (PCU): Applied for the Ben Luc - Long Thanh

Expressway Project (in the Operation Phase)

Step 1: Estimate emissions per PCU-Km for different category of vehicles for 50 km/hour average speed (information source EKB, ADB 2010)

Veh Type Fuel consumption PCU

l/100km per PCU-km Kg/l kg/PCU-km 2w 2 0.5 0.040 2.416 0.103w 3.1 1 0.031 2.416 0.07PC 10 1 0.100 2.416 0.24LCV 12 1.5 0.080 2.582 0.21Bus 28 3 0.093 2.582 0.24HCV 25 3 0.083 2.582 0.22

Step 2: Notice that for 4/6w vehicles CO2 emissions per PCU-km are about 0.24 kg. Step 3: Calculate threshold traffic in PCU likely to generate 100,000 tons of CO2 emissions, annually. Per 1000 PCU, Annual CO2 Emissions for L km long road in tons = Emission/PCU-km*356*L (say A) Threshold PCU to generate 100,000 tons CO2 annually in 1000 PCUs = 100000/A and thus

869. To calculate number of PCUs the project owner should register the total number and corresponding vehicle types passing through each of the seven toll gates on the length of the expressway. Number of PCUs will be calculated based on the ratios used for change from different types of vehicle into equivalent PCU. 870. VEC, the project owner, is responsible for CO2 emission monitoring. No external environmental specialist is needed for this task. Accordingly, budget for this activity will be included in the VEC annual operation budget, no extra budget is suggested for this activity. 871. Annually, VEC will send to ADB a report on the results of GHG monitoring for this project. D. Responsibilities and Authorities for Mitigation Measures and Monitoring

X CONCLUSIONS AND RECOMMENDATIONS

883. The Ben Luc – Long Thanh Expressway Project will play a vital role in improvement of the transport system of Viet Nam. It will contribute to develop socio – economy of the Southeastern and Mekong River Regions. Therefore, the project is strongly supported by MOT, the provinces and people in the project area. The expected impact of the Project will be achievement of increased competitiveness of regional economy along the GMS Southern Economic Corridor in southern Viet Nam and the GMS countries. By expanding access to markets, facilitating the movement of goods, and people, and contributing to connectivity improvements in the GMS, the Project will promote sustainable economic growth, a necessary precondition for poverty reduction. The Project may not have a direct impact upon people living in poverty, but will have indirect impacts through improvement of the investment climate for labor-intensive and export-orientated economic growth. The Project will achieve a more efficient and safer movement of goods and people in the greater HCMC area. Through construction of the project expressway, connectivity of cities and towns around HCMC will be improved and the cost and travel times for the movement of passengers and goods in and around HCMC will be reduced. 884. From primary and secondary data collected in this EIA, the characteristics of the present state of the environment at the districts where the expressway will pass across are summarized below.

(i) The projects area is located in the downstream of the Dong Nai – Saigon river basin; most of the area belongs to wetland with soft, flat and low elevation land.

(ii) At present, water contamination is high at the canals and evident at the rivers where the expressway will go across. Fish populations are poor in species and density.

(iii) At present, at the national roads air and noise pollution is significant, but air quality, noise and vibration levels at most communes where the expressway will be constructed, still meet the Vietnamese Standards.

(iv) In the past most of the area was agricultural land and waste wetland. During the last 20 years, with the rapid urbanization and industrialization a large area was converted for urban, industrial, tourist and aquaculture development. Therefore, natural habitats, biodiversity of aquatic and terrestrial ecosystems were reduced.

(v) Within a distance of 30 km from the project alignment is the Can Gio Protected Mangrove Forest (official name given by Ho Chi Minh City PC) which was approved by UNESCO in 2000 to be included in the World Biosphere Reserve Network. This biosphere reserve is an important site for conservation of mangrove forests, protection of the environment, education in biodiversity and economic development to meet local and national demands.

(vi) The design and construction of viaduct for the expressway will not involve an interchange with the existing Rung Sac highway in Can Gio district. It will go over Binh Khanh Commune, located in Transition Zone of Can Gio Biosphere Reserve. In the past and at present, there is no area of mangrove forest in this commune. The alignment passes through the transition zone of the biosphere reserve. According to UNESCO in the transition zone of biosphere reserve the economic objective is to develop urban areas, industrial zone and economic development to meet the local and national demand. As such, the project alignment in Binh Khanh commune complies with the Vietnamese Laws and UNESCO Guideline. Therefore, it is supported by Ho Chi Minh, Can Gio PCs and Management Board of Can Gio Protected Mangrove Forest.

348

(vii) The area, where the large area of mangrove forest still occurs, is the Thi Vai river banks in Dong Nai province. The project has been designed to minimize impacts on mangroves in the area through construction of a viaduct in densely vegetated areas instead of a road embankment.

885. This EIA has identified adverse environmental impacts due to the project, most of which will be experienced during construction and are therefore, temporary in nature. During construction, communities in the vicinity of the construction site and access roads will be most likely affected by elevated levels of noise and dust emission. Pollution of water resources and the surrounding environment may occur due to earthworks, generation of construction and domestic wastes, disturbance of acid sulphate soils and other project-related activities. During operation, it is anticipated that noise levels at residential areas along the expressway are likely to exceed ambient standards. Exhaust emissions will also contribute to air pollution in the project area. 886. Proper and timely implementation of various provisions of the EMP in terms of mitigation measures, monitoring and capacity building will minimize adverse environmental impacts due project construction and operation. To ensure that adverse impacts due to project implementation will be adequately addressed, the tender and contract documents for civil works for the entire project (ADB and JICA sections) shall include the EMP. Regular monitoring and reporting on the status of EMP implementation shall be undertaken to ensure that mitigation measures are implemented as required and to allow for formulation and implementation of corrective actions, as necessary.

APPENDIX II.2.2. WHO Guideline Values FOR NOISE

The WHO guideline values in Table 4.1 are organized according to specific environments. When multiple adverse health effects are identified for a given environment, the guideline values are set at the level of the lowest adverse health effect (the critical health effect). An adverse health effect of noise refers to any temporary or long-term deterioration in physical, psychological or social functioning that is associated with noise exposure. The guideline values represent the sound pressure levels that affect the most exposed receiver in the listed environment.

The time base for LAeq for "daytime" and "night-time" is 16 h and 8 h, respectively. No separate time base is given for evenings alone, but typically, guideline value should be 5 –10 dB lower than for a 12 h daytime period. Other time bases are recommended for schools, preschools and playgrounds, depending on activity.

The available knowledge of the adverse effects of noise on health is sufficient to propose guideline values for community noise for the following:

a. Annoyance.

b. Speech intelligibility and communication interference.

c. Disturbance of information extraction.

d. Sleep disturbance.

e. Hearing impairment.

The different critical health effects are relevant to specific environments, and guideline values for community noise are proposed for each environment. These are:

a) Dwellings, including bedrooms and outdoor living areas.

b) Schools and preschools, including rooms for sleeping and outdoor playgrounds.

c) Hospitals, including ward and treatment rooms.

d) Industrial, commercial shopping and traffic areas, including public addresses, indoors and outdoors.

e) Ceremonies, festivals and entertainment events, indoors and outdoors.

f) Music and other sounds through headphones.

g) Impulse sounds from toys, fireworks and firearms.

h) Outdoors in parkland and conservation areas.

It is not enough to characterize the noise environment in terms of noise measures or indices based only on energy summation (e.g. LAeq), because different critical health effects require different descriptions. Therefore, it is important to display the maximum values of the noise fluctuations, preferably combined with a measure of the number of noise events. A separate characterization of noise exposures during night-time would be required. For indoor environments, reverberation time is also an important factor. If the noise includes a large proportion of low frequency components, still lower guideline values should be applied.

Supplementary to the guideline values given in Table 4.1, precautionary recommendations are given in Section 4.2 and 4.3 for vulnerable groups, and for noise of a certain character (e.g. low-frequency components, low background noise), respectively. In Section 3.10, information is given regarding which critical effects and specific environments are considered relevant for vulnerable groups, and what precautionary noise protection would be needed in comparison to the general population.

APPENDIX III

AIR POLLUTION MODELING FOR YEAR 2036

APPENDIX III.1. MODELING SOFTWARE USED

ISC3 (Industrial Source Complex Model) a steady-state Gaussian plume model which can be used to assess pollutant concentrations from a wide variety of sources associated with an industrial complex. This model can account for the following: settling and dry deposition of particles; downwash; point, area, line, open pit, and volume sources; plume rise as a function of downwind distance; separation of point sources; and limited terrain adjustment. ISC3 operates in both long-term and short-term modes. The Complete Equation For Gaussian Dispersion Modeling Of Continuous, Buoyant Air Pollution Plumes shown below:

where:

f = Crosswind dispersion parameter

g1 = Vertical dispersion with no reflections

g2 = Vertical dispersion for reflection from the ground

g3 = Vertical dispersion for reflection from an inversion aloft

C = Concentration of emissions, in g/m³, at any receptor located:

x meters downwind from the emission source point

y meters crosswind from the emission plume centerline

z meters above ground level

Q = Source pollutant emission rate, in g/s

u = Horizontal wind velocity along the plume centerline, m/s

H = Height of emission plume centerline above ground level, in m

σz = Vertical standard deviation of the emission distribution, in m

σy = Horizontal standard deviation of the emission distribution, in m

L = Height from ground level to bottom of the inversion aloft, in m

So far, ISC3 v. 2000 is the latest version was released in 2000-2001. ISC3 is used by Environmental Protection Agencies in the United States, Australia, China, Japan and European countries. . . and also be used in projects of international organizations, funded by WB, ADB, IFC, JBIC.

In Vietnam, ISC3 be used to predict the spread of industrial pollution for the Important Economic Region in South of Vietnam (in 1997 and in 2002) and for Important Economic region in Central of Vietnam (in 2000) and for air pollution prediction of East-West Highway Project (1999, 2002).

How to calculate Pollution coefficient applied for ISC3

Pollution coefficient applied for PCU: gr (air pollutant)/1000km issued by US EPA. Load of air pollutants generated in a road section: (Volume of PCU* PCU pollution coefficient /time) x length of road.

Pollution coefficient applied for ISC3: gr/s.m2 = (Load of air pollutants)/time/road area (gr/s.m2)

Selected pollutants: Pollutants calculated for the project include TSP (arising from fuel combustion), NO2 and SO2.

Terrain: chosen terrain is plain and the map uses DEM or XYZ format.

Meteorological parameters use meterorological data provided by the Southern Station for Hydro - Meteorology

Results of the calculations are ISC3 data files with distributed pollutants within the calculated concentrations of pollutants in a day. 58 km length of BL-LT was divided into different section (every 2km), calculated and resulted on a data sheet, analyzing data to find the max figures, mapping the distribution of air pollutions. These results will be processed with GIS software to integrate with the population and forest distribution maps to create the distribution maps of the impact caused by the spread of pollution by emissions from the transport of the project to surrounding areas.

Can Gio, 22 July 2009

Attn.: Southern Highway Projects Management Unit

On 28/07/2009, Can Gio Protected Forest Management Broad received Official Letter 20/KTTGSMT-PIU3.1 dated 27/07/2009 by the Southern Highway Projects Management Unit asking the opinion on impact of the Ben Luc – Long Thanh Expressway Project (the section crossing Binh Khanh commune, Can Gio district) to Can Gio Protected Forest. The Protected Forest Management Broad has the opinion as follows:

The Ben Luc – Long Thanh Expressway Project, i.e. the section crossing Binh Khanh commune, Can Gio district, is located in the Transition zone of Can Gio Biosphere Reserve; the project site does not cross Can Gio protected forest (Binh Khanh commune has no mangrove forest of the protected forest) and therefore causes no effect on the growth of the mangrove forest as well as on the protected of the protected forest. However, it will affect the land use planning of the district and the aquaculture environment in the project site.

Foregoing is the content of the reply from the Protected Forest Management Section.

No. 022/CV-BQL Re.: Opinion for aligning Ben Luc – Long Thanh Expressway (section crossing Can Gio dist., Ho Chi Minh City)

Can Gio, 10 June 2009

Attn.: - Ho Chi Minh City Department of Transport

- Southern Highway Projects Management Unit

It is known from the meeting on 03 June 2009 at the City Department of Transport for giving opinions about the Ben Luc – Long Thanh Expressway Project; according to the project, the instant plan of the expressway (plan 1) has a section that crosses Can Gio district, Ho Chi Minh City. After consideration, the PC of Can Gio district has the opinions as follows:

It is agreed to select plan 1 of the expressway that Consultant TEDIS presented at the meeting.

Attentive matters:

- The task of adjustment of the approved plan for Can Gio district construction, accordingly the juncture of Rungsac road (Can Gio district) with the expressway is 1.35 to 1.50 km from Binh Khanh ferry landing (along Rungsac road). Besides, the ROW of Rungsac road is 30 for the section from Binh Khanh ferry landing to the juncture and 120 m from the juncture to the center of the district; therefore, it is recommended to study a juncture to connect the expressway and Rungsac road at a place that is 1.35 – 1.50 km distanced from Binh Khanh ferry landing.

- The zone to be crossed by the expressway is beyond the border of the protected forest, in the transition zone of Can Gio biosphere reserve; at present, there are residential land lots amid agriculture land of individuals and organizations with land use certificates. - The expressway will cross rivers such as Tac and Tra, Binh Khanh commune, Can Gio district, where there are many passenger and cargo ships and furthermore, bank erosion is significant. Therefore, it is necessary to calculate the passage for ships and to take proper measures against erosion. Foregoing is the opinion of the People’s Committee of Can Gio District. To: P.P. Chairman - As above Standing Vice Chairman - Standing Dist. Party Committee - Standing Dist. PC - LDVP-TH. Doan Van Thanh (signed and sealed)
