1. INTRODUCTION

A draft EIA Report for the Third Highway Rehabilitation Project (hereby HRP-3) hadbeen prepared in May 1999 and was reviewed by the WB Mission in July 1999. Basedon the comments and suggestions of the WB environmentalist a Final Detail EIA Reportwas prepared and submitted to the Bank in late August 1999 (Volume 5 -.EIA ReportJuly 1999). The Bank provided comments on the report and requested for clarificationsregarding noise measurements, alternative analysis, public consultation, andstrengthening of the EMP. To avoid confusion with the Government EIA approvalprocess and condition (see Appendix 1), it was agreed with the Bank mission inOctober 1999 that a separate report be prepared as an addendum to the EIA report inresponding to the Bank comments. Contents of the report was suggested as shown inAppendix 4. The Bank comments on the outstanding issues are as follows:

1. Noise Prediction and Mitigation Measures

Since Vietnamese noise standards are set separately for three time zones and fourland-use categories, the future noise level should be predicted and evaluated in eachtime zone and land-use category as listed below:

Time zones: daytime (06:00-18:00), evening (18:00-22:00) and night (22:00-06:00);

Land-use: schools. and hospitals, residential area, commercial and service area, andsmall industrial factories in residential area.

As a result of future noise evaluation, appropriate mitigation measures should beidentified and incorporated into the Environmental Management Plan (EMP) if futurenoise level exceeds the relevant standard. In particular, emphasis should be placed onnoise-sensitive spots including schools and hospitals along the alignments.

In addition to the above, the noise measures should also satisfy the guidelines given inthe Pollution Prevention and Abatement Handbook.

2. Altermatives Analysis

According to the requirement of OP 4.01 for category A projects, alternatives analysisshould at the minimum include the 'without project" situation and should be mentionedexplicitly in the EA report, i.e., put a chapter in the EA report.

3. Public Participation

Although this EA report describes the state of public participation to some extent, itshould be made in a more explicit manner, i.e., put a chapter in the EA report. Inaddition, it seems that public consultation so far is not comprehensive. The EA reportindicates that an environmental impact study was announced in the newspaper inAugust 1999 and no response was received from the public. More effort should bemade to collect opinions from the public-to hold a meeting an in affected area, to handout leaflets in the local language, to conduct interviews, etc. And then their concernsshould be accurately reflected in the project report. OP 4.0 also requires that theborrower consult the public at least twice: (a) shortly after environmental screening andbefore the TOR for the EA is finalized: and (b) once a draft EA report is prepared.Recognizing that the project was changed from category B to A after issuing the PCD,we understand that the consultation mentioned in (a) above is not possible. Wetherefore recommend that the second required consultation that would inform the publicof the environmental mitigation measures be held as part of the EMP.

4. Environmental Management Plan (EMP)

The EMP should be strengthened to include mitigation measures outlined in the EIA.These measures should also be incorporated in the detailed engineering design.Sufficient funds should be included in the project to implement all mitigation measuresoutlined in the EMP, monitoring, and institutional strengthening.

This report is the addendum to the EIA report in responding to the above Bankcomments. Additional analysis on noise assessment is presented in Section 2 whilemore details on noise equipment and noise sensitive receptors are given in Appendixes2 and 3. It also presents the mitigation measures proposed in the EIA report, however,the detailed actions will be finalized after consultation with local communities inDecember 1999. Section 3 presents the altemative analysis without the project whileSection 4 provides more information regarding the consultation and informationdisclosure activities of the project. As requested by the Bank, a series of meetings withthe local communities on the proposed EMP will be carried out in December 1999 andthe results will be included in the final EMP and its action plan. Section 5 summarizesthe draft final EMP which to be discussed with the local communities. The final EMPand its action plan will be submitted to the Bank after completion of the DD phase.

2 NOISE PREDICTION AND MITIGATION MEASURES

2.1 World Bank comment for clarification

The following comment from the World Bank needs to be clarified in this Chapter asfollow:

Since Vietnamese noise standards are set separately for three time zones and fourland-use categories, the future noise level should be predicted and evaluated in eachtime zone and land-use category i.e. Time zones: daytime (06:00-18:00), evening(18:00-22:00) and night (22:00-06:00); Land-use: schools and hospitals, residentialarea, commercial and service area, and small industrial factories in residential area. Asa result of future noise evaluation, appropriate mitigation measures should be identifiedand incorporated into the Environmental Management Plan (EMP) if future noise levelexceeds the relevant standard. In particular, emphasis should be placed on noise-sensitive spots including schools and hospitals along the alignments. In addition to theabove, the noise measures should also satisfy the guidelines given in the PollutionPrevention and Abatement Handbook

2.2 Present noise level

Based on the noise levels obtained by the EIA Team at the selected sites at the densepopulated areas along the section of Dong Ha-Quang Ngai and Can Tho-Ca Mau(Table 3.13 and Table 3.26, respectively, in Volume 5, EIA Report, July 1999 andTables 1, 2 Figures 1-2 in this Addendum) it is noted that at present the daytime (6 am -6 pm) noise level created by traffic activity at almost all monitoring sites located 5mfrom the road edge already exceed the Vietnamese Permissible Noise Level at the 3Land-use categones: area needed special low noise; residential area and commercial-service area (mixed area). The Vietnamese Standard for Noise (TCVN 5949-1995) isshown in Table 4.7, Volume 5, EIA Report, July 1999. The present average noise levelsat a location 5m from the road edge at the section Dong Ha-Quang Ngai vary from 65.2to 75.7 dBA. At the section Can Tho-Nam Can it vanes from 68.6 to 78.6 dBA. Themaximum noise levels at all monitoring sites at both section are higher than 74 dBA(74.6 - 95.5 dBA)*.

Noise resources are not only vehicle noise (from the engine, transmission, exhaust andsuspension) and road noise (friction noise from the contract between tires andpavement) but are also driver behavior (frequent use of homs) and boat engines (atconnection of road and canal in the Mekong Delta).

Noise levels are in general lower than the standard for industrial zones. However, thislanduse category is not common in the project area. The main common landusecategories along the project sections are residential and commercial, service areas asdescribed in great detail sub-sections 3.2.7 and 3.3.7 and 3.4.1 of Volume 5, EIAReport - July 1999. The areas requiring special low noise are only small spots locatedin the above mentioned landuse categories.

So far, there are no any effective measures for noise control recommended orregulated by the Environmental Management Agencies (DOSTES) in the 2 sections.Most of households who live next to the road do not like to move to places far from theroad for noise prevention.

2.3 Noise Prediction

According to results of noise pollution modelling computed by the EIA Team in variousscenarios of traffic increase in the Dong Ha - Quang Ngai section and Can Tho - NamCan section (Figures 4.13 and 4.14, Volume 5 EIA Report, July 1999) it is predictedthat:

o In 2010 in the normal trafic condition in the daytime (6 am - 6 pm) at 5 m from theroad edge noise level will be about 73 dBA at the Dong Ha - Quang Ngai sectionand 72 dBA at the Can Tho - Nam Can section. This is will be higher than theVietnamese Noise Standard (TCVN 5949 - 1995) for the mixed (commercial andservice) area, for the residential area and for the area needed special low noise.Noise levels will meet the standard for the mixed area (70 dBA) only at the siteslocated over 13 m (at the Dong Ha - Quang Ngai section ) or 10 m (at the Can Tho- Nam Can section) from the road edge.

- The peakhournoise level will meet the standard for mixed area only at sites locatedover 80 m ( at the section Dong Ha - Quang Ngai) or 40 m ( at the section Can Tho- Nam Can) from the road edge.

According to the definition in the Vietnamese Noise Standards schools, hospitals,library, sanatona are sensitive receptors requiring low noise level ( 50dBA at 6 am - 6pm; 45 dBA at 6 pm - 10 pm and 40 dBA at 10 pm - 6 am). To meet this very strictpermissible noise level these buildings (Table 4) would be located over 1.000 metersfrom the road edge (doubling the distance between the road and the receptor results ina decrease of 3 dBA in the noise level) or the noise level have to be reduced by veryspecial and expensive measures.

The daytime noise pollution model indicates that noise pollution will be a significantproblem during the highway operation phase. It is not necessary to apply the model for


ASIA PACIFIC ENGINEERING CONSULTANTS (APECO)In assocation wrtO MaunseY: Mcintyre Pty Ltd, MaunseUt Vetnam,

other time zones, since the Vietnamese Environmental Standards do not permitpollution levels to exceed the permissible value at any time of day.

2.4 Noise mitigation measures

To mitigate noise pollution in the project areas, the feasible measures recommended inthe EIA report are given below:

> Moving the road alignment or diverting traffic away from noise - sensitive areasusing bypass roads. This measure has been applied in various places along NH1.Several bypass roads have been designed by the Project Design Team, forexample at Hue City and Vinh Dien town etc. at the section Dong Ha - Quang Ngai.

> Applying bituminous surface layer over worn concrete roadways or open-gradedasphalt to reduce frictional noise. Maintaining the road surface to avoid grooves andcracks.

> Road design should avoid steep grades and sharp comers to reduce noise resultingfrom acceleration, braking and the use of engine brakes by heavy trucks at criticallocations.

> Setting up noise barriers consisted of earth mounds or walls of wood, metal orconcrete to form a solid obstacle between road and sensitive receptors. Thismeasure is widely applied in Europe, USA, Japan, etc. In Vietnam, this measuremay be applied at schools and hospitals located next to the highway but should notbe applied in residential areas. According to a preliminary interview of residentsliving along the NH1 in Can Tho, Soc Trang and Bac Lieu provinces construction ofnoise baniers in front of their houses is not accept.

v Growing of dense trees around the sensitive areas.

The most feasible measures to be applied for the HRP-3 are enhancement ofenvironmental management, including:

> Enforce noise regulation for vehicles. Vehicles may be permitted to be used whennoise level generated from engine meets the Vietnamese Standard (TCVN 5948 -1995, Table 5);

> Ministries of Police, MOTC and MOSTE should cooperate in checking vehicles,motorbykes before giving licenses for theirs operation and during their operation onthe roads; and

> Do not permit construction of new schools, hospitals, sanatoria, churches andtemples in the noise safety corridor, which will be determined by the EnvironmentalAuthorities.

Detailed application of these measures will be finalized during the Detailed DesignPhase after consultation with the local communities. Appendix 3 identified locations ofthe sensitive receptors in the project area.

3 ALTERNATIVE ANALYSIS



According to the requirement of OP 4.01 for category A projects, alternatives analysisshould at the minimum include the "without project" situation and should be mentionedexplicitly in the EA report, i.e., put a chapter in the EA report.

3.2 General

For the without project analysis of the environmental impact covering natural andsociological impacts, the following is considered:

> Existing conditions> Future condition without the project

The impact on the natural environment is examined by studying the impact on waterpollution, air pollution and noise levels. The impacts on the social environment areexamined by studying the impact of traffic safety and damage of the floods.

In order to clearly identify the impacts on the environment the sections Dong Ha toQuang Ngai, Can Tho to Ca Mau and Ca Mau to Nam Can are treated in separatesections.

The Natural Environment

- Air pollution

In general, at present along the road the major air pollutant is particulate matter (dust).Concentration of particulate matter in all monitoring sites in the dry days at daytime areslightly higher than the Vietnamese Air Quality Standard (TCVN 5937-1995).Concentrations of other air pollutants (SO,, NO., CO, Pb) are lower than the standard,except for some places in the urban areas.

Air quality at various places in Da Nang City in May and August 1999 is shown inTables 6 and 7 demonstrates the present air pollution in the urban area along NationalHighway No.1.

- Noise pollution

It was found that in daytime (6am-6pm) noise levels, at all monitoring sites were slightlyhigher than the Vietnamese Standard for commercial and service area and muchhigher for residential area (TCVN 5949-1995) (Tables 3 and 4).

- Water pollution

Water pollution due to runoff of road, containing solids, heavy metals, grease and oilsinto fields and canals along the road with possible health hazards for the localpopulation.

However, there are not data demonstrating this impact. At present, water pollution ismainly caused by domestic wastes.

* The Social Environment

- Traffic safety

The existing paved road width of approximately 8m, including the shoulders and withoutline marking, results in mixing of pedestrians, cyclists and heavier forms of transport.The negative impact of the lack of shoulders and line marking include an increase of

the risk on cyclist accidents by approximately 25% and pedestrians accidents by 50 %(see Volume 1, chapter 9).

Given the traffic characteristics in Vietnam, a 8m wide road has a capacity ofapproximately 2,300 Passenger Car Units per hour (Volume 1, chapter 9). On allsections this capacity is being exceeded (Table 8), increasing the traffic accident rateseven further.

Source: HRP 3 Study Team estimates from traffic count in December 1998.

Other causes of high traffic accident rates are:

> Traffic regulations are not strictly followed;

> Traffic regulations are not enforced.

These problems are common in Vietnam and create a great number of traffic accidentson the National Roads, particularly on the rehabilitated roads such as National Highway5 (Ha Noi - Hai Phong), National Highway 51 (Ho Chi Minh - Vung Tau), NationalHighway 1 (Ho Chi Minh - Can Tho) etc. According to a statistics in 1998 at the NH 5traffic accidents caused hundreds of people wounded and tens died.

- Flood damage

The hydraulic and hydrology review concluded that several sections lack culvertcapacity for the existing conditions. This means that the embankment of Highway No.1forms an obstruction to the free drainage of flood water and therefore increases thewater level and drainage time upstream of the embankment. The increased water levelwill cause a larger area to be inundated than would be in case of sufficient culverts.

In the rainy season in 1998 a large area in the upstream western site of the NH1 wasinundated for 10 - 30 days. The most serious inundation occured in Duy Xuyen, DienBan Districts (Quang Nam Province) and Huong Tra (Thua Thien Hue) wherethousands ha of rice fields and residantial area were inundated.

During submergence of the road the pavement might damaged due to:

> High velocity of overtopping flow causing erosion and danger to people andvehicles passing the flooded road.

> Washing away of roadbed material (piping), causing potholes.

> Ingress of water at the shoulder, causing structural damage.

> High pore pressure due to a big difference in upstream and downstream water (lackof culverting) might results in macro instability possibly causing sliding and microinstability in the form of seepage.

These processes weakens the pavement and result in high maintenance costs andincreases vehicle operating costs and therefore causes losses to the economy. Atpresent, this problem usually occurs at the section Dong Ha - Quang Ngai.

3.3.2 Future condition without the project

* The Natural Environment

Because of annual economic growth rates in the period 2000 - 2010 at the section willbe 8 - 10%, traffic activity will also rapidly increased even in case of without project.Increase of number of vehicles, motorbykes in the conditions of poor quality road willcreate several impacts on the natural environment:

> Increased air pollution due to increase of dust from the road.

> Increased noise and vibration pollutior, due to potholes and smoothness of theroad.

> Water pollution created by leakage of fuel from vehicles to the road and run-offwater.

Although number of vehicles operated on the road is still small, air and noise pollutionalready exceeds the standard. It is expected air and noise pollution in case of withoutproject will be significantly higher in 2010.

The Social Environment

- Traffic safety

Traffic accident may increase further in comparison with the existing conditions due toincrease of traffic volumes:

The capacity of the existing road is already exceeded as described in the previous sub-section. The normal traffic growth, which has been assumed in this study to beapproximately 12%, will increase the traffic volume and capacity constrains of HighwayNo.1, resulting in diversion to rural roads not being design for these increasesmaintenance costs while the Highway No.1 constrains increase time delays and causeseconomic losses.

Planned economic zones will generate traffic and further increase the number ofheavier vehicles and decrease the road safety.

The approved and presently implemented HRP2 project upgrades the road to a 7mwide carriageway with 2m wide paved shoulders and a 0.5m unpaved verge.Maintaining the geometric status for the less severe flood -prone sections will result inshort sections with a different road geometry and further increasing traffic accidentrates.

- Flood damage

The impact of future floods are equal to these mentioned in the previous subsection,with the exception that more people will be affected due to increased road use andpopulation density in the area.

- Reduction of economic growth

As plan of socio-economic development of all provinces in the section Dong Ha -Quang Ngai, the annual growth rates in the period 2000 - 2010 will be 8 - 10%.Several large industral parks and harbours in this section have been planned. They areChan May in Thua Thien Hue; Dung Quat in Quang Ngai and Chulai Special Zone inQuang Nam. Several tourism areas such as Hue, Da Nang, Ba Ra, Hoi An... havebeen planned to be developed.

Development of all economic sectors greatly depends on transport system. Therefore,in case of without project, foreign and domestic investment into the region will bereduced creating reduction of economic growth in the region.

3.4 Can Tho to Ca Mau Section


The Natural Environment

-Air

In general, at present along the road the major air pollutant is particulate matter (dust).Concentration of particulate matter in all places are slightly higher than the VietnameseAir Quality Standard (TCVN 5937-1995). Concentrations of other air pollutants (SO.,NO,, CO and Pb)are lower than the standard, except for some places in the urbanareas. (Table 9 and 10).

- Noise

It was found that noise levels, at all monitoring sites were slightly higher than theVietnamese Standard for commercial and service areas and much higher forResidential and commercial areas (TCVN 5946-1995). (Table 2 and Figure 2).

At present, dust and noise pollution are major environmental problems caused by roadtransport in this region. Pollution by toxic gasses such as SO2, NO,, CO, HC is stillslight, their concentrations are lower than the Vietnamese Standard for Ambient Air(TCVN -5937 - 1995)

- Water

Water pollution due to runoff of road into fields and canals along the road with possiblehealth hazards for the local for population and aquatic organisms.


- Traffic safety

The traffic safety issues for the Can Tho to Ca Mausection are equal to those of theDong ha to Quang Ngai Section, except for the traffic volumes which are shown in table11.

This section of National Highway No 1 has an existing width of approximately 7.5m andtherefore a capacity of less than 2300 passenger car units per hour. Table 9 shows thatthe capacity of the road is exceeded by its present traffic volume and thereforeincreasing the traffic accident rates.

- Flood damage

The elevation of this road section is above the 10% flood level. The existing roadembankment contains sufficient culverts for cross drainage and therefore has no effecton floods for the flood-prone sections with insufficient culverting in Dong Ha to QuangNgai.



- Air, water and noise pollution is expected to increase due to increase of trafficvolumes. Congestion, due to insufficient road capacity, results in a further increase ofthe pollution. At present, number of vehicles operated on the road is small but air (dust)and noise pollution already exceeds the Vietnamese Standards for residential areas. Itis expected that this problem will be more serious in 2010.

- Impacts on biological resource in this Section will not be increased in comparison withthe present situation.

The Social Environment

- Traffic safety

The increase of vehicle speed and traffic volumes (12% p.a.) on the insufficientcapacity road leads to increased maintenance costs and time delays. The replacementof My Thuan ferry by My Thuan bridge, scheduled for completion in 2000, and Can Thobridge, scheduled for completion in 2005, will generate and divert traffic, resulting infurther congestion of the road and therefore more traffic accidents and increases thevehicle operating costs due to time delays. It is also expected that these developmentswill increase the volume of the heavy vehicle fleet in conditions of bad quality roadresulting in more serious accidents.

- Flood damage

Increased traffic volumes and a shift to heavier vehicles on the poorly drained roadsections result in an increased deterioration rate and therefore unnecessary losses tothe local economy.

3.5 Ca Mau to Nam Can Section



-Air

At present there is neglectable air pollution from the road users, but noise pollution ispresent from the waterway transport (SO2, NOx, dust) and from wind transferring dustfrom earth surface to the air

- Noise

At present there is neglectable noise pollution from the noise users, but noise pollutionis present from the waterway transport.

- Water

Due to the absence of a road system, the waterway transport sector has developedthereby damaging the embankment along the riversides and creating water pollution bywastes and fuel leakage from motorized boats.

- IThe Social Environment

- Traffic access

The earth track between Cai Ran bridge and Nam Can allows only limited access to 2wheel vehicles and is an average of 3 months per year closed due to flooding. Mosttraffic therefore consists to waterway traffic resulting in trip length of up to 8 hours forthis 53 km stretch. The bad access of the most southem part of Vietnam results in aslow down in development of the area and therefore potential economic losses.

- Flood damage

Floods causes road closure for 3 months and in combination with high water tablescauses the earth track to be in bad condition and so reducing traffic capacity further.


a The Natural Environment

There is an expected increase of the pollution for air, water and noise at waterway, butnot from the road users.

Mangrove forests will not be conserved due to increased human encroachment to theprotected areas.

The very restricted access of the area results in much lower traffic growth than in theother sections of the project and thereby restricting potential economic development ofthe area.

At present, living standards of people in Cai Nuoc, Ngoc Hien districts of Ca Mauprovince are lower then other districts in the Mekong Delta although this area has agreat potential in fishery and forestry. Due to low economic development, culture,education and health care in this area are also very poor. This is a reason of increaseof human encroachment into mangrove forests to destroy forest for shrimp culture andfor fuel and to hunt wild animals (turtles, snakes, frogs, birds, ...)

Therefore, in case of without project socio-economic environment will not be improvednatural (biological) environment at the section Ca Mau- Nam Can will be degraded,although environmental pollution will not be more serious than that in the present time.

4 PUBLIC PARTICIPATION AND CONSULTATION



Although this EA report describes the state of public participation to some extent, itshould be made in a more explicit manner, i.e., put a chapter in the EA report. Inaddition, it seems that public consultation so far is not comprehensive. The EA reportindicates that an environmental impact study was announced in the newspaper inAugust 1999 and no response was received from the public. More effort should bemade to collect opinions from the public-to hold a meeting an in affected area, to handout leaflets-in the local language, to conduct interviews, etc. And then their concernsshould be accurately reflected in the project report. OP 4.0 also requires that theborrower consult the public at least twice: (a) shortly after environmental screening andbefore the TOR for the EA is finalized: and (b) once a draft EA report is prepared.Recognizing that the project was changed from category B to A after issuing the PCD,we understand that the consultation mentioned in (a) above is not possible. Wetherefore recommend that the second required consultation that would inform the publicof the environmental mitigation measures be held as part of the EMP.

4.2 Activities during the preparation of EIA and RAP

4.2.1 General

During the FS and the preparation of the EIA report, the guidance of OP 4.01 and OD4.30 and the application of Decree 22/CP improve environmental management andresettlement regarding information dissemination, adequacy of mitigation measures,provision of rehabilitation and support services, monitoring, evaluation and institutionalmeasures was followed. Particular attention was given to reduce the impacts onresettlement and land acquisition.

Information on the Project, resettlement process and mitigation measures for theenvironmental impacts has been regularly provided by PMU1 to all Provincial andDistrict People's Committees. An information letter was sent to every PAP to informthem about the main characteristics of the project and the objectives of the mitigationmeasures for Social and Environmental impacts. Several meetings were held with localauthorities.

During the environmental surveys, DMS and preparation of the EIA and RAP, provincialand district authorities as well as representatives of PAPs have made constructivecomments on major issues relating to the Project, and particularly on resettlementplanning.

4.2.2 Information campaign and consultation prior to reporting

The following activities were undertaken during the preparation of the EIA and RAP.

Activity 1: Media campaign prior to the DMS and Environmental Surveys

Information to the general public in the Project area was given by public speakersystems, letters and announcements in the local newspaper. The contents of the mediacampaign included:

> a brief description of Project components, the content and tentative schedule for the landdemarcation and DMS;

- the cut-off date of the project and

> a request for PAPs and the local authorities to prepare their eligibility documents to show theDMS Team.

Activity 2: Information dissemination by PMU1 to local authorities. PMU1 and theConsultant (APECO) held meetings with the People's Committees at various levels forconsultation on the EIA (including the RAP).

Activity 3: Information dissemination and PAP consultation during DMS.The Consultant provided each PAP wth a letter of introduction about the Project at the tme ofDMS. The letter contained explanaton of the following:

)> Project description;

> Objectives and contents of the survey; and

P Requirement of cooperation and assistance from PAPs and the local authorities.

During DMS, each PAP was also informed about resettlement options and measures tomitigate adverse environmental impacts, and asked to declare their preferred optionaccording to their eligibility.

Activity 4: Following DMS and data analysis, PMU1 and the Consultant held meetingswith provincial, district and. commune representatives at which the following informationhas been presented:

E Project's main components;

> Proposed policies and procedures including proposed resettlement strategies;

> A summary breakdown of impacts within their particular Project area;

> The tentative implementation schedule; and

> Roles and responsibilities of the responsible committees and agencies.

The local authorities were consulted about:

> their opinions about the information given;

> their opinions about mitigation, monitoring and institutional measures in theirparticular area and land availability; and

> identification of land for group relocation.

4.2.3 Public Notification via media

The results of the Environmental Impact Assessment were made public viaannouncement in the newspaper regarding the availability of the EIA report for thepublic at large to respond or comment on the study. The public was also informed thatthe construction work would commence in year 2000. The public could write in, ortelephone to voice their comments, support or objection to the proposed project.

ASIA PACIFIC ENGINEERING CONSULTANTS (APECO)In associabon with: Maunsel MclntyTe Pty Ltd, Maunsel Vietnam,

From the survey and discussions with the public during the survey period, majority ofthe affected people support the project which would bring more benefits to the area andpeople than minimum land and economic losses caused by the project.

Since the publication of the announcement on the local newspaper until the date ofissuance of this report, there were no queries or objections made by any organizationor from the public. It is therefore can be concluded that the public have no majorobjection to the project in term of the environmental issues.

4.2.4 Consultation done by MOSTE

The Final EIA Report (July 1999) has been translated into Vietnamese and submitted tothe National Environmental Agency (NEA) within the Ministry of Science, Technology &Environment (MOSTE). NEA has organized a Review Process by sending the EIAReport to Departments of Science, Technology & Environment (DOSTEs) -Environmental Management Agencies - of 9 provinces in the project area. DOSTEshave organized provincial appraisal committees with presence of scientists,environmentalists and representatives of PAPs, then they have sent their comments toNEA.

4.3 Consultative meetings on the EMP

The major impacts of the project and the proposed mitigation measures (draft EMP inSection 5) will be informed to the local communities , particularly in the sensitive areas.At least 7 local communities will be invited to participate in one to two meetings at eachsection, which will be organized in December 1999 by PMUs with the participation ofthe consultants. In the Dong Ha - Quang Ngai sections, the meetings may beorganized in Hue or Da Nang. In the Can Tho - Nam Can section, the meetings may beorganized in Can Tho or Ca mau city.

Based on the results of the meetings, the final EMP and its action plan will be preparedand the budget will be allocated for the implementation.

5 ENVIRONMENTAL MANAGEMENT PLAN (EMP)



The EMP should be strengthened to include mitigation measures outlined in the EIA.These measures should also be incorporated in the detailed engineering design.Sufficent funds should be included in the project to implement all mitigation measuresoutlined in the EMP, monitoring, and .institutional strengthening.

5.2 Project impacts and mitigation measures per location as detailed in F/S

According to the World Bank's Operational Policies (OP 4.01, January, 1999)"Environmental Management Plans (EMP) consists of mitigation, monitoring andinstitutional measures to be taken during implementation and operation to eliminateadverse environmental and social impacts, offset them, or reduce them to acceptablelevels".

The Environmental Management Plan in Volume 5 (HRP3, July 1999) covers the DongHa - Quang Ngai flood-prone sections and the Can Tho - Nam Can section of NH-1and describes in great detail the following:

>- Mitigation measures in the design and pre-construction phases;

> Mitigation measures in the construction and operation phases; and

> Environmental Monitoring Programs.

The project impacts and mitigation measures are listed in table 13, while table 14 and15 detail the measures to apply per location for Dong Ha to Quang Ngai and Can Thoto Nam Can respectively. The locations of the flood-prone sections and EIA sub-sections as indicated in the tables are shown in figure 5.1 and figure 5.2.

5.3 Environmental Monitoring Program

5.3.1 General

Natural environmental monitoring programs should be implemented in 3 phases Pre-construction, construction and operation of the project.

Monitoring programs in the Pre-construction phase aim at getting ground data onenvironmental quality at the project locations. Monitoring programs in other phases aimat getting data to evaluate the impact of the project and effectiveness of the mitigationmeasures.

The following programs are discussed in more detail

9 air quality monitoring> Water and sediment quality monitoring> Noise and vibration monitoring> Wildlife monitoring

For these monitoring programs the following details are described in the sub-sections:

> Methodology> Pamameters to be monitored> Location and frequency of monitoring during pre-construction, construction and P

operation phase> Cost estimation

5.3.2 Monitoring Programs

Air quality

Methodology

According to the requirement of MOSTE the standard mcnitoring equipment andstandard methods for air sampling, storage'analysis and reporting, regulated by theVietnam' s National Environmental Monitoring System (NEMS) should be applied andthe Vietnam Ambient Air Quality Standard (TCVN 5937-1995) should be applied duringmonitoring in residential areas and the Vietnam standard for Exhaust Emission fromVehicles (TCVN 5948-1995) should be applied for monitoring air emission fromvehicles.

Selected parameters to be monitored

> Temperature, humidity, wind velocity;> Dust (total particulate matter);> Sulphur dioxide (SO2);> Nitrogen dioxide (NO2);

' Carbon monoxide (CO);> Lead (Pb); and> Volatile organic compounds (VOC)

In the construction phase, dust is major parameter to be monitored. In the pre-construction and operation phases all above mentioned parameters should bemonitored.

Location of monitoring sites

> In the Pre-construction phase:

Some selected sites representative for urban, historical, cultural and rural area...along each sub-sections. Due to limitation in the budget only, 5 sites/section will beselected for monitoring.

> In the construction phase

In populated areas or at historical, religious, cultural area significantly affected byconstruction activities.

Location of the monitoring sites will be mobile depending on construction progress ateach sub-section. About 30 sites will be monitored

> In the operation phase

About 8-10 sites in residential areas at each section should be monitored. Thedensely populated areas, such as Dong Ha, Quang Tri towns, Hue, Da Nang Cities,Tam Ky and Quang Tri towns (in the Section 1) and Can Tho City, Soc Trang, BacLieu, Ca Mau City (in the Section 2) will be selected to set up monitoring stations.

Monitoring frequency

> In the pre-construction phase

At least two times, one in the rainy season (from October-February in the Section 1and from May to November in the Section 2) and one in the dry season (from Aprilto September in the Section 1 and from January to April in the Section 2).

> In the construction phase

Air quality monitoring will be undertaken monthly at the peak construction hours orwhen people complain.

> In the operation phase in first 3 years.

Air quality monitoring will be done at least 2 times pear year (in the dry and therainy seasons) in the selected sites, at the peak hours of vehicle operation. After 3years of Highway operation the monitoring frequency will be reduced.

Estimate cost for air quality monitoring

Cost of air quality monitoring with the selected monitoring parameters for one site incontinuous 3 days is estimated as USD 400, including travel, sampling, analysis anddata handling. Thus, the minimum cost for air quality monitoring programs will be USD16,000 (pre-construction), USD 15,000 (during construction) and USD 15,000-20,000/year (during the operation phase).

Water and sediment quality

Water quality and sediment monitoring is requested to be implemented in the pre-construction phase and during construction and operation phases.

Methodology

The standard monitoring equipment and standard methods for water and sedimentsampling, storage, analysis regulated by the Vietnam NEMS should be applied. TheVietnam Surface Water Quality Standard (TCVN 5942-1995) should be applied duringriver or lagoon water quality monitoring.


At each construction site of the large-sized bridges (for example the Bay Hap river),about 3 monitoring sites will be set up: one at the constructing site, 1 at the upstream, 1at downstream of the river.


> River flow> pH> EC> Ss> turbidity

' colour> NH4+> NO3-> Total P> Fe> Al> BOD> grease and oil> Total coliform


Two occasions during bridge construction are recommended, one occasion may belasted in 24-continuos hours, in which 4 sampling times at different tidal fluctuations willbe followed. Monitoring program should be done in 3 phases: pre-construction,construction and after construction.

Estimate cost for water quality monitoring

For one river where a new bridge will be constructed cost of water monitoring is aboutUSD 2,400 (pre-construction), USD 2,400 (during the construction) and USD 2,400 (1year after construction).

Noise and vibration

Noise and vibration during construction and operation activities will be environmentalproblems of the project. Monitoring programs are recommended as follows.

Monitoring methodology

Noise and vibration monitoring should follow the NEMS/ s guideline. The Vietnam noiseand vibration standard for residential areas (TCVN 5949-1995) and for vehicles (TCVN5948-1995) should be applied to evaluate noise and vibration levels caused byconstruction equipment and vehicle operation.



ASIA PACIFIC ENGINEERING CONSULTANTS (APECO)In associabon with: Maunsell McIntyre Pty Ud, Maunseil Vietnam.

TEDI South. CIENCO 625 and Envronmeral Protedion Cetre

' During the construction phase

Noise and vibration will be monitored at the nearest boundary of populated areasand sensitive receptors located near by construction sites.

> During the operation phase

Noise and vibration will be monitored at the boundary of the most denselypopulated centres and sensitive receptors (pagodas, temples, churches, schools,hospitals). Location of noise and vibration sites will be at the same air pollutionmonitoring sites.


I in the construction phase: In the peak hours of construction activities.

' In the operation phase: 1-2 occasions per year, each occasion will last 24 hours toobtain hourly reading on vibration and noise

Estimate cost for monitoring

USD 100 per 24 hrs./site.

Wild life

The project wili cause some adverse impacts on biological resources, particularly inthe Sub-section 2.6. Therefore, an adequate monitoring program on wildlife isnecessary. However, the existing natural ecosystems will be impacted not only by theproject but also by various human activities, so that the project's monitoring programon wild life should focus mainly on the change in wild life diversity and quantity at theselected areas, where the impacts of the project are likely specific.


> Flora: Identification of vegetative species, vegetative cover and density.> Fauna: Wild mammals, reptiles and fish species, identification of rare and/or

endangered species.

Monitoring location

Only one area along the sub-section 2.6 (from Dong Cung to Nam Can).


Annual monitoring on wild life will be done in the duration of 5 years (one year beforeconstruction, 1 year during construction and 3 years after construction for evaluateimpacts of induced development). Biological monitoring in Vietnam is not regulated inthe Environmental Standard, therefore, this activity should be implemented byenvironmental or forestry research centres/institutes, who have experts andexperiences.

Estimate cost for wildlife monitoring

Cost for annual wildlife monitoring in the Sub-section 2.6 is USD 15,000/year.

5.5 Finalizing actions for EMP and Action Plan

To ensure effective implementation of the EMP, agreements were reached during theOctober mission on the follow up step to be taken to finalize the EMP and Action Plan:

> Prepare an action plan acceptable to the Bank, including institutional arrangement,to ensure effective implementation of the EMP during implementation of the projecti.e. pre-construction, construction and operation. This will include consultation withthe local authority and communities and the need for training of key staff - what arethe role of contractors, supervision engineers, DOSTE, other concerned agencies,and PMU1.

> During the detailed design stage, the proposed EMP will be carefully consideredand incorporated into the designs. Due attention should be given to thegovernment and the Bank requirements and the experiences obtained from theimplementation of the HRPI and HRPII, especially on road safety and the executionof the environmental measures during construction and operation.

> During construction, efforts must be made to minimize impacts on localcommunities, especially on safety, accessibility, traffic management,air/noise/vibration pollution and public information should be periodically provided.The contractor will be required to

a) use transportation trucks and heavy construction equipment with goodconditions in line with the national pollution control standards,

B) execute the mitigation during construction as identified in the EMP, andC) pay compensation to the affected people for any damage that occur due to

wrong doing.

> These measures will be included in the bidding and contract documents asappropriate. The supervision engineers will be responsible for monitoring andreporting of the environmental aspects and this task should be clearly indicated inthe TOR. The environmental aspects must be included as part of the progressreport.

> PMU1 and other concerned agencies will take necessary actions to mitigate anyunforeseen impacts during construction.

> To minimize the impacts on safety of road users, periodic training of localpopulation and road users on road safety and traffic management.

> A post-impact assessment on the medium term impacts (positive and negative) onroad safety, air/noise quality, and induced development in the project areas,especially for the Ca Mau - Nam Can section will be undertaken one year aftercompletion of the project and a report should be submitted to the Bank soon after.

> PMU1 will hire a qualified consultant to carry out environmental monitoring duringconstruction and preparation as required in the EMP.

> PMUI will assign one person from PMU1 South to be the responsible forcoordination and monitoring of the EMP.

The project impacts, mitigation measures and steps to be taken for finalizing the EMPand Action Plan are summarized in table 16.

Appendix 2. Description of Integrating and logging level MeterQUEST - Models 1900 and 2000

1. INTRODUCTION TO THE MODELS 1900/2900

The Quest Models 1900 and 2900 are advanced sound level meters which perform a widevariety of acoustical measurements. Both exponential averaged and time integratedmeasurements may be made, with the capability of either internal or external data logging.The output of an independently weighted peak detector may also be displayed or Jogged.Application include laboratory, industrial, community and audiometric measurement andanalysis.

The models 1900 and 2900 provide a numerical readout of measurements as well as a movingbar graph indication. The results of individual sound studies may be stored in internalmemory for future reference. Meter operation is controlled from either the membrane keypador through the communications port. AC and DC output jacks are provided for connecting toexternal devices such as audio recorders, chart recorders, oscilloscopes, etc. Data may be sentto a parallel printer by using special interface cable. The meters are housed in a toughinjection molded plastic case with internal shielding to protect against external electricalinterference, such as that from motor or portable radios.

The Model 1900 delivers Type I accuracy for critical measurements, while the model 2900 isa Type 2 instrument for general field survey work. The model 2900 uses a 0.52 inch electretmicrophone, while the 1900 accommodates a variety of microphones to meet event the mostunconventional applications. As both meters are operationally identical, this manual willrefer only to the model 1900 expect where appropriate.

Options include expanded logging memory and a second RMS detector to allow simultaneousmeasurement of C-A frequency weighted LEQ or LAVG.

Plug in the Model OB-300 combination 1/3 - 1/1 Octave Filter Set and create a 1/3 or 1/1octave band analyzer covering 33 bands from 12.5 Hz to 20 kHz. The addition of the ModelOB-100 Octave Filter Set will create an octave band analyzer covering 10 bands from 31.5 Hzto 16 kHz.

If sound measurements need to be made from a distance, simply remove the microphone/ pre-amplifier and insert either an ICM-10 (10 foot) or an ICM-50 (50 foot) extension cable.Distances of up to 100 feet can be accommodated by adding two ICM-50 extension cables inseries.

With the microphone and preamplifier removed, the meter can accept other input devices suchas the Quest Model VI-90 Vibration Integrator 1900 or 2900, provides a quick and precisemethod of measuring and analyzing types of industrial vibration.

Suggested Contents of the Addendum to the EIA Report

To avoid confusion with the government approval of the EIA report, it is suggested that aseparate report is prepared as an addendum to the EIA report with clear cross reference to theBank comments and the EIA report. The following contents are suggested as a guidance andmore detailed information should be provided in the final addendum.

1. Introduction --- including Bank comments; Approval of MOSTE, rural selection of thesubprojects for the Mekong delta sub-component

2. Noise prediction and mitigation measures -identify sensitive receptors (hospitals, schools,etc.) in the project areas. Since PMU 1 and consultants felt strongly that evaluation andprediction of noise levels according to the time zones and land use types as identify in thestandards would be difficult and not practical at present, main reasons should be given forthis argument. The following support information may be helpful:

Explanation on the method of noise measurements, including its constraintsGraphic presentation of existing noise levels showing a band of average, max, min, etc.Identification of sensitive areas for the project, especially those very close to the roadand likely to have serious impacts due to noise, especially the hospitals and schoolslocated next to the road edge, and identify specific measures for these areas duringconstruction and operationComparative discussion on noise generation along the road according to the timezones/land uses and why it cannot be applied in this caseProposed option for mitigation of noise levels -to be discussed in the consultativemeeting on the EMP.

3. Altemative analysis: (to minimize the environmental impacts, including resettlement and!and acquisition)

Recognizing that the environmental aspect (positive and negative) was well considered andintegrated into the decision making process durng the FS and conceptual design, theseconsiderations should be presented in this chapter. It should be noted that during thealtemative analysis for the rehabilitation works (road width, geometric designs, drainage,alignment, etc.) of the Highway 1, safety and flood protection were the main concems.Small shift of alignment was made to reduce the negative impacts on households and localpopulation and/or encroachment on cultural properties. Adequate details on theseconsiderations for each section should be described.

DH-QN (any realignment, flood level, etc??), Hue city??, by pass??, technicalconsideration (surface, geometric design?)

r . CT-CM (same as above)??CM-NC (same as above)??

It was noted that during the prioritization and selection of the subproject for improvement ofthe Mekong Delta network, the potential negative impact was considered as one of theselection criteria and 10% were given as the ranking weight. The subprojects that requireconstruction of new roads or are likely to have significant impacts were not considered forthe. project. A lower score was assigned to those require works adjacent tocanals/waterways or require new pavement construction wider than the existing pavement.High score was assigned to those would result in positive social impact by diverting trafficfrom populated areas. Other weights ranking were 601/o for economic benefits, 10% forinfrastructure cost; 10% for sub-infrastructure connection; 5% for support to planneddevelopment, and 5% to spatial distribution.

Similar discussion can be presented for the other small subprojects of the MekongDelta network (same as above)??

4. Public participationSummarize activities and results that were undertaken on this aspect for the project,

including those for DMS and RAPst * Summarize the future consultative meetings (on the EMP, RAPS, etc.) to be done

(by whom), how, and when??

5. Environmental Management Plan (EMP) -prepare a draft detailed EMP with clear referenceto the EIA report also with clear description of the works to be undertaken. Due focusshould be given to ensure effective implementation of the EMP to reduce the impacts dueto transportation of construction materials, road safety, air/noise pollution, land use control,and (for Ca Man Nam Can) mangrove protection. The final EMP should be finalized afterthe consultative meetings.

Summary of the project components and subprojects, including the contractarrangement --2 contracts for DH-QN, 3 contracts for CT-NC, and ...?? for other smallsubproject in the Mekong Delta networkAn action plan for each contract (what, by whom, when, cost, included??):Roles and responsibilities of the implementing agencies, including the need for trainingand capacity building -who will be responsible for execution and monitoring duringconstruction i.e. PMU 1, contractors, supervision engineers, local authority, DOSTE?and operations i.e. local authority, MOTC (car/driving licensing??, police), etc.
