I. INTRODUCTION

The productive rural infrastructure development project in the central highlands is funded by ADB. Ministry of Agriculture and Rural Development (MARD) is the project investor. This project will be implemented in the 5 provinces (Lam Dong, Dak Nong, Dak Lak, Gia Lai and Kon Tum) of the Central Highlands.

The long-term purpose of the project is to contribute to hungry alleviation and poverty reduction programs of the Government through sustainable development of the society, ecology and environment at community level by developing infrastructures for production, improving socio-economic conditions and living standards of people in the area. The short-term objectives of the project are (i) to rehabilitate and upgrade deteriorated or damaged irrigation system and rural roads; (ii) to strengthen management capacity and implementation of ODA projects, infrastructure management at community including province, district and commune levels to gradually improve living standards and conditions of the poor in the project area in the Central Highlands; (iii) to build models, institutional policies on "water saving irrigation technology for strategic and economic valuable plants" and "management and exploitation of irrigation schemes sustainably with the participation of all economic sectors ".

One sub-project of the project is “repairing, upgrading Cu Jut irrigation works system, Cu Jut district, Dak Nong province” that will be implemented in three communes including Nam Dong, Dak Drong and Cư Knia, Cu Jut district, Dak Nong province. This Initial Environmental Examination (IEE) of the subproject is prepared to meet the requirements of environmental safety of ADB and the Government of Vietnam. It includes 11 parts:

II. POLICY FRAME, LEGISLATION AND MANAGEMENT

2.1 ADB policy

ADB safeguard policy statement (SPS) 2009 imposes safeguard requirements for all its funded projects. The SPS 2009 clarifies reason, scope and contents of the environmental assessment. Safeguard policy statement emphasizes on environmental and social sustainability in progress of economic growth and poverty reduction in Asia and the Pacific, therefore the objectives of SPS focus on:

i. areas Avoid adverse impacts of projects on the environment and affected people, where possible;

ii. Minimize/mitigate and/or compensate for adverse impacts on environment and affected people when avoidance is not possible; and

iii. Help borrowers/clients to strengthen their safeguard systems and develop the capacity to manage environmental and social risks.

SPS requires preparing environmental safeguard documents in the process of preparing a project including environmental management plan (EMP). The borrower/client needs to monitor EMP implementation. The monitoring will identify outstanding issues of EMP implementation and propose appropriate mitigation measures. Periodic monitoring report on EMP activities will be submitted to ADB every semi-annual during construction of the project.

Moreover, all subprojects under the loan 3032-VIE need to follow the specific guidance on environmental assessment as stated in the Environmental Assessment Review Framework (EARF) of the project, prepared by the project owner and approved by ADB. The subprojects under loan 3032-VIE only categorized as Category B or C will be included in the list of eligible subprojects for possible funding under the proposed Project. It is anticipated that all eligible subprojects will fall into Category B, whereby some adverse environmental impacts are expected, but of a lesser.

The subproject ““Repairing, upgrading Cu Jut irrigation works system, Cu Jut district, Dak Nong province” is selected based on the project’s EARF that may cause the insignificant environment impacts and ranked as categorized B because: (i) It is not close to any preserved areas; (ii) there are not any households whose houses will be affected due to land acquisition to the subproject implementation;;(iii) it estimates there are about 36 households whose land will be acquired to implement the subproject but not any households will lose more than 10% their land. (iv) some environmental adverse impacts but these impacts will take place within subproject sites but can be controlled by mitigation measures. Thus an IEE needs to be prepared with an enclosed EMP.

2.2 Environment regulations of Vietnam government

The project must also comply with the environmental regulations. The Vietnam legal framework comprises of the following items:

- The Law on Environmental Protection adopted by the National Assembly of the Socialist Republic of Vietnam dated January 01, 2015. The law regulates general environmental protection requirements, policies and resources for protecting the environment;

4.2 NATURAL ENVIRONMENTAL CONDITIONS

Air quality

The subproject is located in the mountainous area. There is no industrial or mining activities are taking place.

Center of Technology & Environment and Natural Resources Management - University of Agriculture and Forestry Ho Chi Minh City took 3 samples at Cu Pu irrigation works, 3 samples at Đăk D’Rông irrigation works and Đăk Diêr irrigation works in September 17, 2014. 7 parameters including noise, dust, SO2, NO2, CO, temperature from each sample were analyzed. The analysis results showed that air quality around the project was quite good, all the parameters are within limits of National technical standards for ambient air quality QCVN 05 : 2013/BTNMT. (See more details of ambient air quality analysis in annex 4)

Noise and vibration

The subproject is located in mountain area with low traffic density and opened green space. Moreover, it is found that Industrial/mining activities are underdeveloped in the area, therefore noise level is very low.

The measurement of noise level in comparing with National Technical standards on noise level, QCVN 26:2010/BTNMT indicates that sub-project area is in good condition without noise pollution, noise level in the Cu Pu reservoir area: 49.5 – 61.0 dBA (See more details of ambient air quality analysis in annex 4)

Climate and natural disasters

The subproject area is influenced by the tropical monsoon and plateau tropical monsoon climate. The year is divided into two distinct seasons:

- The rainy season is from May to October (accounting for approximate 90% of annual rainfall).

- The dry season is from November to April of the next year (accounting for approximate 10% of annual rainfall). May and June are the transitional months (beginning of rainy season).

(source: Statistical Yearbook of Dak Nong province, 2013)

Natural disasters: A report by Dak Nong – Department of Agricultural and Rural Development (DARD) said that there are typically natural disasters in Dak Nong in recent years (i) sweeping floods; (ii) landslides; (iii) Floods; and (iv) droughts

- Sweeping floods took place in Dak Nong in recent years. In which one on September 14,15 and 16, 2012 in Dak Glong and Tuy Duc districts. It swept away 14 bridges and three persons. According to local people, this is a fiercest sweeping flood in 10 recent years through the province. Another one on October 07, 2013 in Quang Tan commune, Tan Duc district, it swept away temporary bridges, trees and farms and two persons died.

- Land slide often has taken place in the southern districts as Dak Song, Dak Dlong, Dak R Lap, Tuy Duc and Gia Nghia town. From 1992 to present, this phenomenon has happened with different extents and has risks, but not clarified reasons. In recent years land slices often takes place (i) in constructing the national highway No14 due to too high slope talus development; (ii) Gia Nghia-Quang Khe road; (iii) and bauxite mining areas etc..

- Flood phenomenon often takes place in the northern districts including Krong No and Cu Jut where have rather flat terrains. Like other provinces in the central highland, rivers and streams in Dak Nong do not have dykes so when it rains a long time, water from rivers, streams will flow to lower areas. Some typical floods in



Page 16


Dak Nong was (i) on October 10, 2006, a flood in Dak Nong river has sunk hundred houses as heavy rain in days in upstream areas. As a result water level has risen up 2-5m and caused the flood. (ii) On September 10-28, 2012, a flood caused flooding for produce farms at Dak R’moan, Gia Nghia. (iii) on December 29-30, 2013, water on rivers and streams of Dak Nong reached peaks and had risks to happen sweeping floods in areas in Ea Krong river, Cu Jut district but luckily it did not happen.

- Drought, climate in Dak Nong has two clear seasons, rainy season is from May to October and dry season from November to April. Since deforestation for agriculture takes place commonly while rainy volume is reduced, rainy season finished sooner so surface and ground water has reduced significantly.

In Spring -Winter Crop of 2004-2005 , Dak Nong Province is damaged heavily by drought, ten thousands crop plants are dried & complete loss, mostly coffee with approximately 30,000 ha, about 3,000 ha of pepper, 2,000 ha of wet rice are damaged with value of approximately 2,000 billion VND ( Source : Study on Drought assessment of Dak Nong – Phan Thi Thanh Hang – Institute of Vietnam Geography & Science –Technology)

Topography and soil

- The subproject area is dominated by tectonics of plateaus; the terrain is relatively complex, only irrigated areas of the reservoirs are relatively flat. The topography is lower from West to East, from South to North; the average elevation is about 330m. The topography is with alternate valleys, rivers and streams.

- Sub-project is located on an area with 4 main categories of soil as follows: Yellow land on clay, black soil on basalt and Jail, red-brown soil on basalt and converged sloping valleys.

Surface water resource - The entire system of rivulets and streams in the subproject area is in basin of Serepok River flowing from South to North through the boundaries of two provinces of Dak Nong and Dak Lak and flows into the Kingdom of Cambodia.

- In the subproject, there are 03 reservoirs: Cu Pu reservoir, Dak Dier reservoir and Dak D’Rong reservoir.

- There are some streams flowing through communes such as: Ea Gang, 1,5km from Cu Pu reservoir, stream flowing Nam Dong and Tam Thang communes; Dak Dier stream at the southwest of Dak Dier reservoir; Dak D’Rong stream at the Southwest of Dak D’Rong reservoir. Around the reservoirs, there are also a lot of swallow brooks.

The above water resources are for domestic usage and agricultural activities of the local people.

Underground water Groundwater in subproject area is without pressure and located at the depth of 5 m - 30 m. Local people exploit it for domestic purposes.

Water quality

The 6 samples of surface water had been collected and analyzed with 10 parameters in 3 areas of subproject. The results of analyses have been compared with National technical standard for surface water quality QCVN 08:2009/BTNMT proves that almost



Page 17


parameters are in limits except Fe-total in 3 samples (NM 4 in Dak Drong; NM 5 & NM 6 in Dak Dier).

There is 9 parameters of groundwater quality at 6 wells of households around 3 reservoirs (Cu Pu, Dak Dier and D'Rong) were sampled and analyzed by the Centre of Technology & Environment and Natural Resources Management-University of Agriculture and Forestry Ho Chi Minh City in September 2014 showed that all parameters were within the allowable limits of QCVN 09: 2008/BTNMT. Coliform indicator in the groundwater samples exceeded the threshold from 50 to 3,600 times (Coliform = 150 – 11,000 MPN / 100 ml of 02 groundwater samples of two households living in Cu Pu reservoir area)(Annex 4).

Flooding Flooding occurs only at cultivation area in valleys or adjacent to streams where altitudes are lower than residential areas and roads. Flooding occurs rarely, which takes place when heavy rainfall continues several days.

Terrestrial fauna and flora

+ The main flora in the subproject area includes agricultural crops (paddy, cassava, maize, beans, coffee, pepper, rubber...);

+ Terrestrial fauna in the area includes cattle, pigs, chickens, etc.;

+ No protected wild animal has been found in the area.

Aquatic fauna and flora + Aquatic fauna: fish, shrimp, eels and snails ...

+ Aquatic plants: algae, duckweed, grass ...

+ No aquatic fauna & flora species listed in the Red Data Book of Vietnam

Protected areas No ecological/protected area is within or near the subproject area. The closet protected area to sub-project is National Park of Yok Don, but really distance towards south-west of Dak Drong commune;

4.3 ENVIRONMENTAL AND SOCIAL CONDITIONS

Unexploded bombs, mines

The construction activities will be taken place at 03 reservoirs, irrigation canals and connecting roads to reservoirs.

However, almost construction places are in existing foundations, which had been built and used in recent years (Dak Drong – 2002; Dak Dier – 2011 and Cu Pu – 2001), therefore no need for checking UXO in those places. Only areas of expanded canals, roads and soil mines will be checking UXO, but in small areas and those places have been cultivated for long period;

Land use

Land adjacent the sub-project area includes: (i) agriculture and forestry land; (ii) non-agricultural land, distributed in the communes as follows:

V. ENVIRONMENTAL IMPACT SCREENING

5.1 Positive impacts

Constructing the subproject "Repairing, upgrading Cu Jut irrigation works system, Cu Jut district, Dak Nong province" will bring positive impacts on environment and society as follows:

- It will ensure water to irrigate initiatively for 532 hectares of wet paddy, 285ha of coffee, pepper and 216 hectares of maize, 400 hectares of cotton and crops.

- It links the traffic from residential areas with production areas and works so that transporting materials and fertilizers for production as well as agricultural products will be more convenient. It creates favorable conditions for mechanizing agricultural production, bringing scientific advances into production, intensive cultivation to increase crop yields. The sub-project also reduces cultivation and labor costs and improves income of local peoples in the subproject area.

- It contributes to early completion of criteria No.2 - on transport, criteria No.3 - on irrigation, criteria No.10 - on incomes, criteria No.11 - on poverty rate of the new rural criteria in construction plan of new rural areas, which have been approved and are deployed at the locality.

5.2 Negative impacts

However, the subproject could also create several negative impacts, especially during construction phase, which need to be managed through appropriate mitigation measures. The negative impacts from subproject could be summarized in the following table.

Risk when detecting unexploded ordnance

Yes Moderate Negative Temporary

Description: Unexploded ordnance detection along the constructed road & canals may be risky for detectors and local people. However, the Cu Pu, Dak Dier and D'Rong reservoir had been constructed since 2001 therefore; detecting unexploded ordnance had been done. While the upgraded roads are in the existing ones which small adjustment, and the new constructed canals are located in the fields, which have cultivated so long, therefore the possibility of finding unexploded ordnance is very low. though the possibility of finding unexploded ordnance is low, its consequences, if explosion occur, causing to detectors and local people are high, which could be death or losing body parts. This activity needs to be managed carefully by authorized people.

Objects : Detectors and local peoples living closed to UXO points.

Affected level: This impact is moderate.

Location: Impact could occur in Cu Pu reservoir as well as along the whole road and canals.

Time: Short time during the detection and treatment period.

HHs due to site clearance (land acquisition)

taken place in existing foundation and alignment, however, sub-project components still require the land acquisition. However, the area of land need to be acquired is not much and 0.88 ha of losing land in Cu Pu reservoir (as rising dam crest) is under management of Irrigation Unit of Cu Pu and no need compensation. The acquired lands are in management areas of reservoirs, canals and roads as well as in productive areas, therefore, almost acquired lands are agricultural land, except material storages and 03 camps will be located in vacant land.

The acquisition of agricultural land will affect 36 HHs of 180 peoples, in which 10 of them are minorities. However, as described above, because the scattered of sub-project activities, the acquired land of each household is limited with small amount for permanently acquisition, while temporary acquired land will be returned after completion. Even though, the acquired of productive lands, though not much, of local people could slightly burden on their economic situation. Therefore, compensation plan need to be prepared and implemented.

In addition, this impacts has been informed to local people through public consultation, and all affected households have agreed to development of sub-project as well as voluntarily donate their land.

Objects : Affected peoples to be land acquired in Nam Dong, Cu Knia and Dak Drong Communes.

Affected level: Thus, social impact due to land acquisitions is minor due to these affected HHs will get beneficiary from upgraded road that it creates favorable condition for travelling from resident area to the agricultural production area & surrounding areas. However, compensation program still need to be implemented to reduce economic burdens for affected

households.

Location: 36 households along the upgraded roads and canals.

Time: Both permanent and temporary during preparation and construction phases.

Description: Subproject will raising dam crest elevation from 509.7 to 510.8 m, this make 0.88 ha of land will be submerged permanently. However, the losing area around Cu Pu reservoir is management land of reservoir, and managed by Irrigation Unit. This land is uncultivated land, only glasses, shrub. Therefore, no forest land will be lost. However, it will impact on grasses , shrub in Cu Pu reservoir area;

Objects: Vegetation cover of 0.88 ha will be submerged as raising dam crest

Inappropriate construction plan in term of time to crop activities of local people


Description: Although the construction period is only 12 months but it can cause significant impacts on crops of local people if the construction schedule takes place at the same time with crop activities of local peoples, then could potential impact on socio-economic situation of local people. In fact, the construction of Cu Pu reservoir, and irrigation canals, have to be implemented mainly in dry season, which are the same period with cultivation. So that, this impact need to be managed and mitigated carefully;

Objects: Crops of local peoples are irrigated by subproject canals

Affected level: Because of potential consequences, this impact is considered as moderate;

Location: on all construction sites of the irrigation component

Time: temporary

Canal design is inappropriate with use and does not consider climate change

Yes

Minor

Negative

Permanent

Description: Inappropriate technical consideration during design of dam and canals can be listed as (i) inappropriate consideration on risk of landslide and soil erosion (ii) it can become a dyke that blocks water flow and cause local flooding in rainy seasons. (iii) Climate change/flooding issue has not been taken account into their design. According to “Report on Climate Change Scenarios of Vietnam, MONRE-2011”, With medium emission scenarios (B2): By the end of the century, annual rainfall would increase by about 2 to 7% in most of the regions. In Highland Region, including Dak Nong, where to be affected at least in competition with other areas in Vietnam, forecast is an increase about 0.9 - 3% (0.9% for Dak Nong) compared to 1980 – 1990 period.. In general, the dry season rainfall would decrease while rainy season rainfall would increase. However, with medium emission scenarios (B2): by the end of the century, maximum one day rainfall in the North Region would increase by about 50% compared to 1980 - 1990 period, about 20% in the Central North Region. Otherwise, maximum one day rainfall would decrease in the Central South & High Land, the South Regions about 10% to 30 % (10% in High Land Region). However, it may occurs extraordinary one day rainfall, which 2 times bigger than compared to current record in different regions

In dry season, rainfall decrease 10-14 % for High Land Region. The increase of temperature in accompanying with less rainfall in dry season could result in drought or less water availability, while the high concentration of rainfall as well as increase magnitude of extreme rainfall

could lead to extreme hazards such as flooding, landslide.

The in appropriation of design without considering CC impacts in reservoir and canal designs could result in significant impacts such as lacking and/or without water for irrigation during dry season, which is less rainfall in future, then reduce productivity. In addition, the higher precipitation and extreme rainfall could cause to flood and/even emergency of reservoir (this impact has been analyzed in operational phase).

However, the aim of sub-project is increase water availability for irrigation during dry season and concrete dam for ensuring safety during operation, especially during rainy season as improving existing works of dam and canals. In addition, the design of sub-project has carefully considered hydro-meteorological data series including during past years & extreme events and future trends of climate change as reducing potential impacts.

Objects

� Crops of local peoples are irrigated by subproject canals

� Local peoples in downstream of 3 Reservoris : Cu Pu, Dak Dier & Dak Drong

Affected level: Sub-project improve situations of existing reservoir and canals with consideration of climate condition, therefore, this impact is insignificant.

Location: All upgraded canals & Cu Pu reservoir.

Time: Permanent.

II. Construction phase

Landslide, soil erosion or sedimentation

Yes Minor Negative Temporary

Description: The construction activities, especially excavating, filling/ embankment work and storing materials, taken place in reservoirs of Cu Pu, Dak Drier & Dak DRONG as well as in upgraded roads and canals will create debris and/or cause materials falling into surface water sources. If they are not collected, it could cause to increasing sedimentation in the canal bed, blocking water flow from main canal into the branches due to debris, solid waste not collected properly; sedimentation may affect the rice fields of the local peoples in Nam Dong, Dak Drong and Dak Dier communes. However, as described in material sources, the excavated soil will be used for upgrading of management/ production/ interior field road along the canal system. In addition, the amount of excavation and embankment at each construction place is quite limited and scattered of construction activities and mainly implemented during dry season, therefore the magnitude of impact is small and duration of impact is short.

Location: Slope of the upgraded roads and canals bed and Cu Pu reservoir, in which with the highest potential impact is in slopes of Cu Pu dam because of the extent of workload

Time: Temporary during the construction phase.

Polluted surface water


Description: surface water on Cu Pu, Dak Dier, Dak Drong reservoirs, Ea Gang, Dak Dier, Dak Drong streams and other small streams surrounding the subproject area could be polluted due to construction activities. Those are (i) domestic wastewater from 03 worker camps; (ii) grease from construction machine maintenance and (iii) runoff water passing through from constructional areas/activities during rainy days as well as (iv) discarded soil and/or sludge from excavation, embankment in Cu Pu reservoir, and upgraded canals and roads as well as materials storage. If such pollutants falling/flowing into water bodies could result in water pollution, which reduces water quality for irrigation, domestic use (which is quite limit currently) as well as impact on aquatic-ecology in sub-project area;

However, because of the limitation (100 workers) and scattering of workers (03 camps) and construction machines, the generations of domestic wastewater (approximate 10 m

3/day but in 03 communes) and the

grease are limited, as well as the amount of constructing materials into water bodies during rainy days is also small. In addition, the construction of Cu Pu reservoir and its works mostly conducted during dry season with withdrawing all water in Cu Pu reservoir, therefore, the extent of impact is small and controlled in according to previous impact of increasing sedimentation into water bodies;

Objects:

� Water in Cu Pu , Dak Dier, Dak Drong reservoirs,

� Ea Gang, Dak Dier, Dak Drong streams

Affected level: Because the significant role of surface water bodies, this impact is considered as moderate, an appropriate mitigations need to be implemented;

Location: Cu Pu, Dak Dier, Dak Drong reservoirs and their irrigation canals are the main potential locations of this impact, however, nearby water surface bodies such as, Ea Gang, Dak Dier, Dak Drong streams and other small streams need to be concerned also..

Time: Temporary during the construction phase;

Noise and vibration


Description: The upgraded road of the subproject is connecting roads between reservoirs, residential areas and in field paths. Noise from construction machines such as concrete mixers, bulldozers and from material transportation trucks may impact on residential areas

along the upgraded roads.

Objects

� Resident areas closed to 3 reservoirs : Cu Pu, Dak Drier, Dak DRong

� Resident areas along the material transportation roads & upgraded roads.

Affected level: The impact is insignificant because extent of the road construction component is small so only few equipment’s will be mobilized to the site, the irrigation component is far from residential area (400m);

Location: Residential areas in Cu Kniwa, Nam Dong and Dak D’Rong communes and travellers.

Time: temporary during the construction phase

Air pollution Yes Minor Negative Temporary

Description: The construction activities will generate dust, air pollution, particularly in dry/sunny days. Dust could also be generated from excavation activities and operation of trucks on the inter-commune roads, or mobilizing mixing concrete, which need to be managed to reduce impacts on local people. Other air pollutant such as NOx, SO2X will be minor since the number of construction equipment mobilized on the site will be small. However, the construction is scattered and the extent of construction activities per place is limited, therefore, the transportation vehicles and operation of construction machines are also limited. In addition, according to site visit, the construction of irrigation canals is distance, at least 400 m from residential areas. And the number of people travelling on roads is quite small;

Objects : Resident areas closed to 3 reservoirs : Cu Pu, Dak Drier, Dak DRong. Resident areas along the material transportation roads & upgraded roads.

Affected level: This impact is minor;

Location: Residential areas in Cu Knia, Nam Dong and Dak D’Rong communes and traffic participants;

Time: Temporary during the construction phase

Soil pollution Yes Minor negative temporary

Description: Soil quality in the subproject area could be affected by (i) domestic wastewater from 03 worker camps; (ii) grease from construction machine maintenance and (iii) domestic and construction waste (solid waste). Soil could be also impacted due to scattering material and death concrete from construction site. If those wastes are not collected and treated in proper manners, it could contaminate soil, especially wastewater with high contaminants and grease as hazardous substances.

Affected level: This impact is minor, but still need to be managed in waste management section;.

Location: The agricultural area along the irrigation canals and rural roads component;

Time: Temporary during the construction phase;

Local flooding

Yes Moderate negative temporary/permanent

Description: Constructing concrete canals or roads may block local water flows in rainy seasons and generate local flooding. Sometime, design is inappropriate or contractor will not fully follow the technical specification, which could lead to blocking existing intakes, culverts and/or, material, spoil on the flow. The scattering construction material/waste to streams/river could also lead to block the water flow. This could effect on crops of local people. However, the construction schedule has planned to work mainly in dry season, as well as withdrawing all water in Cu Pu reservoir, therefore, the possibility of flooding by blocking water flow is low. In addition, the historical data has indicated that there is no heavy flooding in sub-project areas and construction activities do not implement on existing intakes, culverts, therefore the existing drainage system is remained;

Objects: Crops of local peoples that irrigated by subproject canals and local peoples in the beneficiary area

Affected level: The level of impact is moderate, therefore the management measures need to be fully considered and implemented;

However, during construction, small vegetation covers within the reservoirs of Cu Pu and Dak Drong, and along upgraded roads and the newly constructed canals could be destroyed. However, the affected flora is invaluable. In addition, during construction of canals, soil and rock can slide down the canals and affect aquatic ecological environment. However, the extent of construction is small and fragmented in many places, therefore it will not significant impact on canal aqua-ecology. Furthermore, the construction of Cu Pu & Dak Drong reservoirs required to withdraw all water, this could result in disappearing of aqua-species available in reservoir currently, and take time to recover after completion of construction. However, the site assessment has indicated that the aqua-ecology in Cu Pu and Dak Drong is very poor and this reservoir is almost out of water storage function because of penetration.

Objects:

• Vegetation covers within the reservoir of Cu Pu and Dak Drong as well as upgraded roads and canals

• Aquatic flora & fauna in Cu Pu & Dak Drong reservoirs

These could cause to occupational accidents during working and/or traffic accident for people passing through construction places. In lesser consequences, the workers may get sick because of unsafe living conditions, unsafe food and inappropriate personal protection equipment. However, few workers concentrated in each construction place, as well as low traffic density along constructed road, which results in less people being exposed to this impact. In addition, the construction activities do not require complicated skills, as well as required to follow environment and labor safety requirements, therefore it is low probability of occurring of accidents;

Objects: Workers in the sites and residential areas along the transport route and near the canal construction area;

6.3 Building capacity for EMP implementation

The relevant stakeholders need to ensure the EMP implementation as their responsibilities. All CPMU, Dak Nong PPMU, CSC, CC need to appoint officers/staffs to in charge of environmental management. However, most of these officers/staffs are also assigned for other works and they are not specialized in environmental management. Thus, to ensure EMP is implemented in compliance with sponsor policies and Vietnamese legislation, these officers/staffs must be guided /trained on EMP implementation capacity building. Training on EMP implementation must be held for different groups with different requirements.

- Dak Nong PPMU and CSC: The staffs that are in charge of environment will be trained (at least once in the first 3 months of the project) on monitoring and preparing environmental reports.

- Construction contractor: Will be trained (immediately after contract signing) on implementing mitigation measures and preparing reports.

IX. GRIEVANCE REDRESS MECHANISM

9.1 Purpose of the mechanism

During the deployment of the subproject, local people are disseminated environmental protection activities such as EMP. Negative impacts on the environment may occur during the construction and operational phases. Any comments/ suggestions of local people will be solved quickly, transparently and protected by law, particularly for affected people by the subproject. Complaint handling mechanism was classified by level and responsibilities of involved parties.

9.2 Grievance redress mechanism

Per the environmental management frame, there are 03 steps to redress complaint as below:

Stage 1: If a household has any complaint he/she can submit a complaint to the CPC-community monitoring board. CPC will work with CSC and CC to solve complaints.

Stage 2: If the complaint is not resolved, the complainant will submit an application to the Cu Jut DPC to resolve the complaint.

Stage 3: If more than 15 days but no response from Cu Jut DPC, the complainant may submit a complaint to the Dak Nong PPC (through Dak Nong DONRE). Dak Nong PPC will require Cu Jut DPC to solve the complaint. In case the complaint is still not resolved, Dak Nong PPC will require environmental police to investigate and requested stakeholders to resolve the complaint. See the mechanism in figure 1 below:

Figure 1: Grievance redresses mechanism
