INTRODUCTION

Background

Can Tho city is the center of the Mekong River delta. The city has experienced over 120 years of development and has achieved many accomplishments in economics, culture, science and engineering. However, the city's infrastructure is still insufficient and seriously degraded adversely affecting peoples' quality of life and urban landscapes. Due to such conditions, Can Tho city needs to develop upgraded infrastructure to secure its socio-economic future. Therefore, implementing the National Urban Upgrading Project, Mekong Delta region (MDR­UUP), Can Tho city sub-project will benefit many areas including improvement of infrastructure, sanitation, living conditions, roads, ponds, and lakes. The sub-project will also provide technical assistance to government authorities and stakeholders. The Can Tho MDR­UUP sub-project includes five components:

Component 1: Tertiary Infrastructure Upgrading In Low-income Areas

Component 2: Supporting Primary and Secondary Infrastructure

Component 3: Resettlement Site

Component 4: Implementation and Project Management

Component 5: Technical Assistance to the Ministry of Construction to Implement NUUP and for Project Coordination

A full Environmental Impact Assessment report, a detailed resettlement and compensation plan report, and a development plan report for ethnic minority have been prepared to ensure the project will be implemented to safeguard environmental and social issues in compliance with Vietnamese laws and regulations and the World Bank's Safeguard Policies, including the World Bank's Environmental, Health and Safety Guidelines.

CHAPTER 2: BASELINE CONDITIONS IN THE PROJECT AREA

2.1. Geography and climate

Can Tho city is a Class I city under the management of the Central Government. The city is the center of economy, finance, trade and advanced science and technology in the Mekong River Delta with a well developed and diversified waterway and highway transport network.

Can Tho city is surrounded by the following provinces: An Giang in the North, Hau Giang in the South, Vinh Long and Dong Thap in the East, and Kien Giang in the West. Total area of the city is 1,401.61 km2

, which includes five urban districts: Ninh Kieu, Binh Thuy, Cai Rang, 0 Mon and Thot Not, occupying about 295 km2

, and four suburban districts and outlying communes, wards and townships occupying approximately 1,106 km2

•

Can Tho's terrain is flat with an average elevation ranging from 0.8 - 1.0m above the sea level. Can Tho city is characterized by many rivers and canals; the major waterways flowing through the city are the Hau River and Can Tho River and several major canal systems.

The monsoon season lasts from May to November. The total annual rainfall in 2009 was 1,247.7 mm. The highest temperatures occur in April while the lowest are in January. Storms and typhoons may occur in May and October; the average number of potential storm events is 63 days/year. The flood season usually extends from July to December due to heavy rains upstream; flooding peaks mostly happen in September and October. Local flooding is caused by high tides and rains. With maximum rainfall amounts of up to 100 mm/day, inundation levels may reach about 0.2 - 0.5 m.

Can Tho city is influenced by tidal regimes of the Hau River, and the semi-diurnal tidal regime of the East Sea. The highest water levels can reach 1.93 - 2.0 m above sea level.

2.2. Socio-economic conditions

The total population of Can Tho city was 1,189,555 in 2009, of which the urban population was 783,104 or 65.8%, and the rural population was 406,451 (34.2% of the total population. The average population density of the city is 1,189 people per km2 and annual popUlation growth rate is 7.9% (2010). Average per capita income is 463,500 VND/month (about US$22 equivalent). In general, the poverty rate in the LIAs is about 24%, and the employment rate is estimated at about 71 %.

The Kinh ethnic community predominates in the project area, but in three LIAs (1, 3, 6) ethnic Khmer people account for a significant percentage of the population. There are 15 temples and pagodas and 16 schools located near the project works.

2.3. Urban infrastructure and services

Can Tho city has five water treatment plants: Can Tho No.1 (50.000 m3/day), Can Tho No.2 (40,000 m3/day), Tra Noc (10,000 m3/day), Hung Phu (10,000 m3/day) and 0 Mon (2,400 m3/day). Raw water is withdrawn from the Hau, Can Tho and 0 Mon Rivers. Among the 31 LIAs, there are 5 LIAs where households are still without water meters.

10

Both Binh Thuy and Ninh Kieu districts have no separate wastewater systems, and only a small percentage of alleys have adequate drainage systems. The drainage capacity of existing lakes and canals is poor, resulting in water logging and local flooding after heavy rains. Flood levels can reach about 0.3 - 0.4 m in some places, lasting for several hours. In the 31 LIAs, wastewater and domestic wastes are not collected but are discharged/disposed of directly into lakes and canals, thereby causing serious pollution.

Municipal solid waste is mainly collected from 4 districts: Ninh Kieu, Binh Thuy, Cai Rang, and 0 Mon). The collection and transport capacity is about 416 tons/day. The waste collection rate is 55% of the city's total waste generation. Two landfills service the city: (i) Tan Long landfill in Phung Hiep district in Hau Giang province with total area of 20.8 ha, and (ii) Phu Thu landfill in Phu Thu ward in Cai Rang district with a total area of 3.5 ha; it can be expanded to 6 ha.

2.4. Environmental baseline

Analysis of air samples shows that air quality has deteriorated due to dust and vehicular exhaust fumes. Air pollution concentrations and noise levels are high, and not in compliance with current national standards.

Surface water in the subproject areas is contaminated with organic matter and microorganisms from waste and wastewater discharges. The concentrations of BOD5, COD, N are 1.2 - 4.3 times higher than the regulatory threshold. The coliform count is 10 - 100 times higher than the current threshold.

Local groundwater is contaminated by ammonia and coliform in the 4 districts of the project area, exceeding the standard threshold by 1.8 - 24 times. Groundwater pollution is likely caused by wastewater leaking from abandoned or improperly sealed wells; the excessive use of fertilizers may also contribute to groundwater pollution.

The concentration of heavy metals in the sludge in canals that are proposed to be dredged, is lower than the current Vietnamese standards. Therefore, dredged sludge can be used for leveling land or as fill material.

CHAPTER 3: SUMMARY OF ASSESSMENT OF NEGATIVE IMPACTS

When the project is completed, the overall impact will be positive. The total number of direct beneficiaries from the project is 46,205 people, including: 26,075 people (from component I), 19,598 people (from component 2), 532 people (from component 3) and the indirect beneficiaries are 479,466 people. Nevertheless, the project will cause some negative impacts on the local environment and the local population. Therefore, effective implementation of mitigation measures will be necessary.

The potential negative impacts of the project's subcomponent on the physical, biological, and socio-economic environments are identified using the checklist method, including assessment of the levels of impacts during the preconstruction, construction, and operation phases. Potential negative cumulative and social and impacts on physical cultural resources (peR) have been identified separately.

3.1. General impacts

Based on the analysis of baseline data, field visits, and discussion with key officials and stakeholders, the potential negative impacts on the physical, biological, and socio-economic environment caused by the project have been identified. Table 3 summarizes the potential impacts by the project subcomponents. The level of impacts are assigned as follows: None (N) -no impact; Low (L) - Small works, minor impacts, localized, reversible, temporary; Medium (M) - Small works in urban/sensitive areas, medium scale works with moderate impacts of which most are reversible, reducible and manageable, localized, temporary; High (H) - Medium scale works in small urban Isensitive area, large scale works with significant impacts (socially and/or environmentally) of which some are irreversible and require compensation. The residual impacts of the project, after implementation of mitigation measures discussed in the EMP, are expected to be mostly negligible.

3.2. Site specific impacts assessment

3.2.1 Component 1

(1) Construction phase

Impacts on ethnic minority

There are no Khmer households displaced in the project area. Only one household of Mr. Pham Van Tuan at alley 3 and LIA 2 will lose 3m2 of agricultural land (accounting for 8.3% of his total land area) due to alley expansion.

Impact from sludge transportation

Volumes of dredged materials from Mieu canal (2,900m long, LIA 12, 13) and Ranh canal (600m long, LIA 31) are 1,493.5m3 and 3,242m3

, respectively. The dredging activities are conducted mainly by hand and the dredged materials will be transported by special trucks to Cai Sau landfill. Sludge transport routes are proposed for Mieu and Ranh canals as following:

+ Mieu canal (12km): Mieu canal -+ Binh Thuy street -+ CMT8 street -+ 30/4 street -+ Quang Trung street -+ Cai Sau landfill

+ Ranh canal (12km): Ranh canal -+ Nguyen Viet Dung street -+ National Highway No.1 -+ Quang Trung street-+ Cai Sau landfill

The dredged material transportation process also generates a large amount of dust and other air pollutants due to fuel consumption.

(2) Operation phase

Impacts of temporary discharge of wastewater into rivers

Installed drainage systems will collect wastewater from 3,535 households (15,909 people) of 12/31 LIAs and discharge directly into receiving water sources. The predicted sewage volumes range from 2,912m3 (in 2015) to 4,705 m3 per day (in 2025). These impacts will be assessed in more detail with Component 2.

Risk assessment of temporary flooding caused by raising road level

There will be 100 alleys upgraded. However, most of them are only few hundred meters in length and will be increased about 20-40 cm in elevation. There are only 12 alleys longer than 400 m which could have some risk of flooding. This impact is not great because after completion of drainage systems, the drainage capacity is also significantly increased. The flooding risk only occurs in short periods; a few hours on certain days when heavy rainfall and high tide occur simultaneously. Some alleys run along the river and canals (LIA 1, LIA 19) where house levels are much higher than the existing road level. The flooding effect only occurs in a short-time and can be minimized.

3.2.2 Component 2

(1) Construction phase

Dredged material

Total sludge volume of dredged materials from Bun Xang lake, Ngong canal, Sao canal and canal at the south of Bun Xang lake will be 233,035 m3

• Sediments will be dredged by shell

19

scrapers, and then loaded on barges for transporting to Cai Sau landfill. According to the sediment quality sampling results in the dredged canals and lake, pollutant and heavy metal concentrations are below the permitted standard, QCVN 03:2008. The sediment/dredged materials can be also used as leveling material or farmland soil conditioner after pretreatment.

Dredged material transportation

Dredged material will be transported by barge starting from Bun Xang lake, Ngong canal, Sao canal and the Southern canal -+ Cai Khe canal -+ Hau River -+ Can Tho River -+ Cai Sau sludge dumping landfill. The one-way transportation distance is estimated to be 10km and barge capacity is 100 ton. Dust and pollutants generated from dredging equipments TSP, S02, N02, CO, and THC. Generated pollutants from the transport of dredged materials include HC, CO and NOx.

Impact assessment of construction of water supply line for LIAI - section through 0 MonBridge

According to the project design, the steel water-supply pipeline for LIAI has a total length of 114m and a diameter of 150mm aligned over the bridge installed on a V -shaped steel frame . Pipeline construction and installation are simple and not obstructive and will not affect traffic on the bridge during the construction and operation.

(2) Operation phase

Impacts on water quality of receiving sources

In operation phase, drainage renovation installed along routes in Le Binh Ward (component 2) and 12/31 Lias (Lia 2, 4, 6, 10, 11, 14, 17, 18, 20, 21, 22, 24) (component 1) will be

temporarily discharged untreated domestic wastewater into 0 Mon, Binh Thuy, Can Tho

Rivers. They will increase environmental pollution risk in these rivers. The calculation results

in comparison with class A2, QCVN 08-2008 and wastewater quality of the World Bank

Environmental, Health and Safety Guidelines (Table 4) show that 0 Mon, Binh Thuy, Can Tho

Rivers are still able to receive pollution loads except NRi. The temporary discharge of

untreated wastewater will increase ammonia concentrations in Can Tho River slightly above

allowed standards, class A2, QCVN 08-2008 (0.5 mg/l) (WB HSE only has standard on total nitrogen (10 mg/L) not for amonia). Therefore, for long term, it is necessary to collect and

treat wastewater to meet permitted standards before discharging into surrounding environment, as well as control ammonia discharges from non-point sources entering these nvers.

Estimated solid waste amount is 125, ton/day arising from canals: Sao canal, Ngong canal, Southern canal of Bun Xang lake and Bun Xang lake. The calculation results for Component 2 for canal sedimentation shows that Component 2 contributes to open flow and requires significantly periodic sludge dredging of Sao canal, Ngong canal, and Southern canal of Bun Xang lake. Sediment deposition will depend on the suspended solid concentrations of Hau River. So wastewater discharge to the lake basin does not significantly impact dredging frequency. The sludge dredging frequency to clear sediment build up in lake and canals is 80 years for Sao canal, 86 years for Ngong canal, 117 years for canal at the south of Bun Xang lake and 38 years for Bun Xang lake.

3.3. Socio~economic impacts

Land Acquisition and Resettlement

Detailed information regarding the nature and scale of the impacts and proposed mitigation measures are provided in the "Resettlement Plan" (RP) report which was prepared separately. There are no indigenous people affect~d by the Can Tho city subproject.

Based on the RP, the impacts due to land acquisition and resettlement include the following:

Other potential social impacts on local communities are transportation obstructions, road safety or public safety, labor accidents, or disruptions to communities during site clearance, construction, and operation.

3.4. Potential impacts to sensitive facilities

The project will not directly impact historical and cultural monuments, religious sites, schools or health facilities during the land acquisition process. However, during the construction phase, construction material transportation and construction activities can affect sensitive points. There are 15 temples, pagodas, churches and 16 schools which could be affected by dust and noise during construction phase. Most sensitive areas more than 10m from construction sites. A few of them are as close as 5 m including: Van Phuoc pagoda, national historic and cultural monument - Hau Giang An Nam Communist Party, Ngoc Hoa monastery, Thien Hau temple, Bach Chu Su temple, Linh Thanh pagoda, Long An pagoda, the Duc Me Hang Cuu Giup Cathedral, Kim Ngoc temple, Thanh Quy seminary, Nguyen Du Primary School, Thai Hoa kindergarten, Trung Vuong primary school, and Le Binh kindergarten.

3.5. Cumulative impact assessment for relative projects

1. KFW project. This is considered an associated subproject to MDR-UUP subproject in Can Tho City since it will treat wastewater collected from MDR-UUP prior to discharge. As such, due diligence work has been conducted by the PMU/consultant and below are the detailed information and findings of the due diligence work.

KFW project

~ Scope of work

Can Tho drainage and domestic wastewater treatment project (KFW) with capacity of 30,000 m3/day.night in the frrst stage and extended to 30,000 m3/day.night in the second stage, in the area of2lha. The project owner is Can Tho Water Drainage and Supply Company. The objectives of the project are to build a new collection system and upgrade the old sewer system to collect and treat wastewater of 10 wards, including An Phu, An Lac, An Hoa, Xuan Khanh, Thoi Binh, Cai Khe, Tan An, An Cu, An Hoi and An Nghiep of Ninh Kieu District.

~ Relationship with MDR-UUP project:

The collected wastewater from MDR-UUP (16/31 Lias including Bun Xang lake) will be pumped to the KFW treatment plant. The drainage system of some Lias in Ninh Kieu district, and the drainage system of Bun Xang lake of MDR-UUP project witt be connected and associated with the drainage network of the KFW project.

Wastewater flow from the project area will account for 38% of the total design capacity of the KFW plant (60,000 m3/day). However, it will not overburden the capacity of the treatment plant because this flow had been included in the design of the KFW project.

~ Sources of Finance

The capital source is from the German Development Bank (KFW) with the total investment of 18.723 million Euro.

The collection system and wastewater treatment plant of the KFW project have been

22

started since 2007 and will be completed at the end of2012. ~~--~--~--~~~--------

The EIA of the project have been approved by Can Tho DONRE and evaluated by environmental specialist from the German government. Below are summary of the impact evaluation for each project component:

);> Newly building separate drainage systems for wastewater and rainwater

Digging ditch, canal to install water pipe to cause dust, noise and to affect on living activity of people on surrounding areas.

Flooding: The execution process can cause local flood at improper and prompt arrangement of drains.

);> Waste water treatment plant

The treatment position selection is very important action to ensure effective treatment, support of people and maximum restriction of impacts on environment and people living. Design works for the components are suitable with the general planning of Can Tho City to ensure safe distance to residences, discharge gates at the downstream of Can Tho River and the treated wastewater must be met the Viet Nam environmental standard of type A, TCVN 5945:2005 (now it is replaced by the QCVN 14:2008/BTNMT) before discharging to receiving source.

Most of the negative environmental impacts are insignificant, short-term and reducible. Mitigation measures have been properly proposed in EMP including mitigation measures, roles and responsibilities of stakeholders concerning to the environmental management, monitoring and the capacity building program.

Community consultation has been conducted during project preparation. Almost participants agreed with the contents of the project. However, some comments asked the PMU must comply with the mitigation measures proposed, particularly with odor emissions from the wastewater treatment plant.

Proposed mitigation measures in the approved EIA report of the WWTP project foUowas:

);> Mitigation measures to treat generated sludge of the WWTP

Generated sludge from WWTP processing will be treated by the technical diagram following as: Activated sludge ~ Sludge pump ~ Sludge conveyor, press ~ to transport to landfills or recycle into fertilizer.

);> To control tbe quality oftbe treated wastewater of the WWTP

According to the approved decision of the EIA report by Can Tho province People's Committee - Department of Natural Resources and Environment (DONRE), the effluent of the WWTP must meet standard of type A, TCVN 5945:2005 (now it is replaced by the QCVN 14:2008/BTNMT).

);> Mitigation measures to treat odor and pathogens microorganisms

To prevent odors, to spray EM (effective microorganism) regularly during the WWTP operation period.

To plant trees to create buffer areas separated from residential areas should be performed adequately and construct walls (fences) around.

To spray insecticides to kill flies, mosquitoes and insects which have the potential to cause disease at the sludge treatment area.

23

Environmental management program has been proposed in the EIA report, has mentioned the roles and responsibilities of stakeholders in the implementation of the environmental management plans for the KFW project.

Environmental monitoring program proposed in the EIA report, including monitoring indicators, locations, frequency and applicable standards. Monitoring frequency of environmental quality is 4 months per time during the construction period and 6 months per time in the first operation year.

Due to the schedule, the project will be completed at the end of 2012 and will not coincide or overlap will with the implementation of the MDR-UUP subproject. The negative cumulative impacts of MDR-UUP and the KFW project will only occur at the drainage systems of some Lias in Ninh Kieu district and Bun Xang lake. Cumulative impacts are expected to be insignificant.

Cooperation between two PMUs need to be established in order to:

2. Cai Sau sludge landflll

Exchanging information on the environmental mitigation compliance of two project's contractors

Properly arranging schedule (especially related to heavy load work) to avoid construction activities occurring at the same time and same place.

Cai Sau sludge landfill

)0> Scope of work

Cai Sau sludge landfill has been designed to contain sludge of WWTP and dredged material of MDR-UUP. Sediment from dredging activities of the MDR-UUP project in Can Tho city will be also transported and treated at this site.

)0> Relationship with MDR-UUP project

All dredged material from MDR-UUP project in Can Tho city will be disposed at this landfill.

)0> Sources of finance

Local budget

The curent area is 3,500m2 which are being built and will be operated in the end of 2011. This landfill had been approved to expand to about 5-6 ha in 2012 by Can Tho City People's Committee, which should be completed and ready when the MDR­UUP subproject commences implementation.

Environmental protection commitment of this project was certified by the People's

Committee of Cai Rang district No. 25/GXN-UBND dated on July 13ni, 2011. Below

are summary ofthe impacts for each project item:

)0> Assessment of options to select the location

The location to construct Cai Sau landfill has enough land for treatment and landfill of sludge ofWWTP and dredging material ofMDR-UUP.

The distance from the landfill to residential areas is reasonable to limit the direct impacts to residents (noise, dust, and odor) by the waste transportation

24

and treatment; it is around 2 km radius.

The landfill location is at the end of the main wind direction.

~ Assessment of negative impacts on the implementation of Cai Sau sludge landfill: construction phase, operation phase and closure of landfill.

Construction phase: (1) change air quality, noise, vibration and dust emissions by digging activities, transportation vehicles of materials and waste and construction machineries; (2) change water quality by wastewater from camps of workers and truck washing before going out of the site; (3) change soil quality by solid waste generation from workers, (4) other impacts: occupational safety, transportation, landscape change.

Operation phase: (l) wastewater from leachate of landfill, and from worker and operator activities, (2) gas emission from landfills by decomposition of organic matter and gases (N2, H2S, C~), noise from trucks, (3) other impacts: fire risk, occupational safety and impacts on public health by creating growth medium flies and disease-causing microorganisms.

Landfill closing period: (1) wastewater: similar with landfill operation phase if fmal cover and surface water drainage systems are not designed, installed and operated reasonable, (2) gas emission: gases (N2, H2S, C~) from landfill; (3) other inlpacts: subsidence landfill, ignition risk and gas dispersion from landfill sheets, re-landscape.

The environmental impacts are significant: Leachate and gas emissions from landfill,

development of flies, sticks and microorganisms in operation period. The EMP has

been proposed including mitigation measures, roles and responsibilities of

stakeholders for environmental monitoring, management and capacity building

programs.

~ Mitigation measures to treat leachate from landfill

Landfill leachate will be collected by the pile HPHO 0200 perforated tube, the end of each pipe leachate collection arrangement of pumping station rubbish to leachate treatment system.

The quality of wastewater output has met standard of type A, QCVN 25:2009 IBTNMT.

~ Mitigation ~easure to treat gas emission from the landfill

Gas emission is collected by vertical wells spaced. Pipe HOPE 0200 collects gas from wells ..

~ Mitigation measures to treat odor and pathogens microorganisms

During the operation phase, daily use soil to cover layer to prevent odors, spray EM (effective microorganism) regularly, especially after rain.

To plant trees adequately to create buffer areas separated from residential areas and construct walls (fences) around.

To spray insecticides to kill flies, mosquitoes and insects with high potential to cause disease.

Environmental monitoring program proposed including: monitoring indicators, monitoring location, frequency and applicable standards. Monitoring frequency of environmental quality is 6 months per time in the construction period and 6 months per time in the operation period.

25

Assessment of The upgraded landfill has been designed and constructed following the national standards with sufficient technical facilities for solid waste treatment. The capacity of landfill is enough for the MDR-UUP project. Thus, the impacts generated from dumping of solid waste will be minimized within scale of landfill. As calculated, about 237,770.5 m3 of dredged sediment of MDR-UUP will be transferred and dumped into the Cai Sau landfill. The landfill totally has capacity to treat this sludge. Environmental impacts and other impacts of Cai Sau landfill were assessed and its mitigation measures were proposed to ensure that it could receive and treat all slud e enerated in the ci . The environmental monitoring program needs to be developed. It is included (but not limited) by:

Air quality monitoring Groundwater monitoring

26

CHAPTER 4: MITIGATION MEASURE

This chapter identifies measures to mitigate the key negative project impacts during construction (which include site clearance, ground leveling, and construction) and operation. Given that most key impacts will occur due to civil works and transportation of construction/waste materials, many of the potential negative impacts on physical, biological, and social environment can usually be mitigated through a set of general measures that are typically applied to construction projects to minimize impacts such as noise, dust, traffic disruption, wastewater generation, etc. As part of the Environmental Management Plan (EMP) for the project these general measures have been transformed into a set of standard environmental specification that will be incorporated into all bidding and contract documents of the project. These measures are referred to as Environmental Codes of Practice (ECOPs), and they will be applied to mitigate typical and general impacts the project's civil works. The scope and content of the ECOPs are presented below.

ECOPs are a set of actions and measures to mitigate the general negative impacts during construction. They describe typical actions to be taken by contractors, supervised by the construction supervision consultants (CSC) during construction, and monitored by the communities and the Independent Environmental Monitoring Consultant (IEMC). These ECOPs also cover the applicable provisions under Section 4.0 on Construction and Decommissioning of the IFC-W orId Bank Group Guidelines for Environmental, Health, and Safety (EHS). The detailed ECOPs will be incorporated into the bidding and contract documents (BD/CD) during the detailed design stage. The scope and content ofthe ECOPs is limited to construction activities for small and medium-size contract works. The impacts of such works are of limited extent, are temporary and reversible, and can be managed readily with good construction practices.

The ECOP measures identify typical mitigation actions for the following types of impacts:

- Dust generation - Air pollution - Impacts from noise and vibrations - Water pollution - Drainage and sedimentation control - Management of stockpiles, quarries, and borrow pits - Solid waste management - Management of dredged materials - Disruption of vegetative covers and ecological resources - Traffic management - Interruption of utility services - Restoration of affected areas - Workers' and public safety - Communication with local communities - Chance finds of cultural or archeological artifacts

The detailed ECOPs (Annex 1) are cross-referenced to the respective equivalent Vietnamese regulations, standards, and codes of practice.

If impacts require site-specific mitigation measures that are not adequately covered in these generic EeOps, they must be addressed separately in the EMP. For example, the above Eeops do not cover impacts from worker camps - assuming they would not generally be needed for small urban works projects - and impacts from large works, such as dams, bridges, tunnels, and major roads. The EeOps cover small dredging operations; however, operations generating very large amounts, or seriously contaminated, sludge would need to be handled through a separate set of measures outside of the scope of these EeOps, such as in a dredging and materials management plan (DMMP - Annex 2). Social impacts caused by involuntary resettlement or involving ethnic minorities are addressed in other safeguard instruments.

CHAPTER 5: MANAGEMENT AND MONITORING PROGRAM

Prepared as a part of the EIA, an Environmental Management Plan (EMP) is a safeguards instrument that is typically used in many projects. It consists of information on, and guidance for, the process of mitigating and managing adverse environmental impacts throughout project implementation. Typically in Vietnam, an EMP comprises a list of typical mitigation measures to be carried out by contractors and others, an environmental monitoring program, capacity building, organizational arrarigements and responsibilities, and the estimated cost of EMP implementation and monitoring.

There is a comprehensive regulatory framework in Vietnam related to EIA preparation, environmental standards, protection and management of forests and cultural property, and other aspects related to construction and operation of facilities and infrastructures in Vietnam. This EMP in consistent with these regulations.

To facilitate effective implementation of the EMP, the PPMU will: (a) Establish an Environment and Social Unit (ESU) responsible for ensuring timely implementation of the EMP, including monitoring, reporting, and capacity building related to safeguards; (b) Assign the Construction Supervision Consultant (CSC) to also be responsible for supervision of the contractor's safeguard performance as part of the construction contract and this requirement will be included in the CSC's terms of reference; and (c) One Independent Environmental Monitoring Consultant (IEMC) is hired by PMU-MOC to assist the ESUs in performing its task.

Can Tho City Water Supply Company, URENCO, and the Department of Transport will be responsible for implementation of the mitigation measures during the operation stage of the project and they will ensure that the mitigation measures are implemented and adequate budget is provided. The Provincial Steering Committee (PSC) chaired by the Chairman or Vice Chairman of the Provincial People's Committee (PCP) will provide the overall policy guidance and oversight of the project implementation. Roles and responsibilities of the specialized agencies and the Departments of Planning and Investment and Natural Resources and Environment (DONRE) will also be critical.

There are two main parts to this EMP. Firstly, the City will use Urban Construction Environmental Codes of Practice (ECOPs) for urban construction works. Environmental codes of practice (ECOPs) are mitigation measures for generic impacts from project activities during the construction phase; they must be included in the bidding documents as requirements directed to the construction contractor. ECOPs are not a formally recognized World Bank safeguards instrument but their use, as part of an EMP, is a convenient and effective way to ensure that the main generic, common and typical construction impacts are adequately mitigated during project implementation.

If impacts require site-specific mitigation measures that are not adequately covered in these generic ECOPs, they will be addressed separately in the EMP. These ECOPs also do not cover impacts (i) from worker camps (camps will not be needed for small and medium urban infrastructure projects), (ii) from large works, such as dams, tunnels, large road and bridge projects (which are not part of this project). Social impacts caused by involuntary resettlement or involving ethnic minorities are addressed in other, social safeguard instruments. The ECOPs

cover dredging operations producing relatively small amounts of sludge, whilst very large amounts or seriously contaminated sludge would need to be handled through a separate set of procedures outside of the scope of these ECOPs.

Activities carried out to mitigate impacts due to land acquisition and resettlement are presented separate safeguard documents (in the RPF and RP); they will be carried out and monitored separately.

Also included in the EMP are related measures, above and beyond actual mitigation measures. This includes the PPMUs' EMP program, including capacity building and safeguard training; and environmental monitoring.

5.1. Environmental management program

5.1.1. Management of impact on project sites

Table 6 presents site-specific impacts and mitigation measures that are not fully addressed through the application of ECOPs. This may be because the impact is not a typical one and is not included in the ECOPs, because the severity of the impact goes beyond the scope of the mitigation measures in the ECOPs, or because simply of the very specific nature of the mitigation measure that is needed.

• Before starting construction, construction management plan and traffic management plans in the construction sites will be informed to local authorities and communities in order to request their cooperation and discuss with them to fmd out the feasible traffic management plans, especially on main transportation routes, high traffic density or more activities of production and business or religious activities, e.g. roads in Le Binh ward.

• Establish temporary paths for residential and business households; avoid traffic on main roads at rush hour if possible; the temporary paths must be determined before construction and upgrading when needed.

• All roads must be restored like the old status as soon as possible. During and after construction, contractors must clean and wash surface roads and alleys, sidewalks, roadsides to ensure traffic safety and sanitation of roads.

• All constructing vehicles used for the project must be clearly stated (e.g. paste the project logo and the project relative information) or registered. If any vehicle does not comply, the project staffs or communities can detect and report to managers.

• Install protective fences or warning signals, lighting to ensure safety for traffic vehicles in the construction site. The separation and physical signs must have reflective strips or maintain a signal light system that help pedestrians and vehicles can easily recognize and avoid the working sites.

• Must maintain barriers/ protective fence at least at 1.5 m high, which defme the boundary of working sites and not allow anyone to encroach and ensure traffic order in residential areas.

• Respect lanes reserved for traffic, plan routes for construction vehicles to avoid traffic congestion, prohibit contractors parking motor vehicles encroaching roads, especially in small and high traffic areas.

• Traffic-separating subjects should be used appropriately during peak hours; separate clearly lanes for cars and motorcycle, bicycle, walkers; promote separation of one­way when necessary.

• Request the assistance of traffic polices, the direct local authorities to solve problems and risks (e.g. accident, congestion)

• Consult and disseminate information to all business and enterprises to early alarm and help them to have active plans to reduce impacts (e.g. adjust goods transport time, working time, travel route, transportation means), typically for large businesses on Cach Mang Thang 8 street, extended Nguyen Van Cu street and National Highway No.91B.

• Disseminate the construction plans to local authorities, management officers of sensitive areas (e.g. kindergartens, schools, hospitals, pagodas, churches, clinics) to allocate and separate traffic reasonably.

5.2. Environment monitoring program

The Environmental Monitoring Program is a key element of the EMP. Its main objective is to check and ensure that (a) the potential negative impacts of the project are minimized; (b) the EMP is effectively implemented; and (c) the EMP is adequate to mitigate the potential negative impacts. Given that monitoring the implementation of the RP will be conducted separately, the environmental monitoring program will comprise (a) monitoring the safeguards performance of the contractors during site clearance and construction, (b) environmental quality monitoring, (c) monitoring the effectiveness of the EMP.

It is essential to design the monitoring program - in conjunction with the selected monitoring locations, parameters and frequencies - in such a manner to be able to record both, the overall performance of the project works as well as the short-term impacts due to construction activities. The environmental monitoring program will be implemented during construction at three levels:

• Monitoring the level of compliance with mitigation measures, • Monitoring the environmental,parameters set out in the EIAs for each of the works,

and • Community-based monitoring.

Monitoring of Contractor's Safeguard Performance

Three levels of environmental safeguards monitoring will be implemented as follows:

- Routine monitoring: This will be done by the Construction Supervision Consultant (CSC) as assigned by the PPMUs. The CSC will include the environmental monitoring results in the monthly project progress reports.

- Periodic monitoring: This will be done every six months as part of the overall monitoring of the EMP implementation. The environmental and social unit (ESU) of the PPMUs, assisted by the Independent Environmental Monitoring Consultant

37

(IEMC) will also monitor the contractor performance every xis months and the results will be reported to the PPMUs and the WB.

- Community monitoring: Monitoring by local communities will be conducted following Government practices, with technical and management support from the PPMU.

To ensure an acceptable level of environmental quality, monitoring of dust, noise, vibration, air quality, and water quality will be .made at project-specific locations that are likely to be most affected by the construction activities. Specific monitoring locations may also be requested by local authorities and/or communities for specific purposes. ESU/IEMC will have overall responsibility for the monitoring program.

The following are the key issues, citeria and scope of monitoring that will be taken into account in the implementation of the monitoring program:

- General Construction Impacts: local flooding; traffic congestion and/or disruption, especially in residential areas; air quality, and noise and dust levels in residential areas; surface water quality upstream and downstream of construction sites, with specific attention paid to impacts on local residents;

- Implementation of site-specific EMPs that require specific monitoring activities that are not covered by the ECOPs nor by the Vietnamese lregulations, standards and codes. Such monitoring activities will be as agreed with local agencies and communities during the preparation of the EMP and monitoring program.

- Implementation of Dredged M.aterials Management Plan (DMMP): for all sludge and similar material excavated from the project work sites that exceeds the national thresholds for toxic substances, a site-specific DMMP will be used. Amounts, levels of heavy metals, if any, locations and activities at disposal sites, and impacts on local residents will be monitored, based on a water quality monitoring plan with specific stations and parameters for monitoring impacts on other water users.

- Monitoring the Effectiveness of the EMP: The ESU assisted by IEMC will monitor the overall performance of the EMP implementation during the detailed designlbidding stage as well as during construction and the first year operation of the facilities to ensure that (a) appropriate dredging and disposal of drainage sludge is properly carried out, in accordance with the DMMP, (b) other impacts identified in the EMP are effectively managed and mitigated; (c) traffic management is adequate and the levels of impacts are acceptable, i.e. there are no new complaints nor any outstanding cases, and (d) all typical general impacts are mitigated in accordance with the ECOPs. Results are to be kept in the project file for possible review by PPMU and the WB. Cost for the monitoring will be part of the PPMU cost.

The following tables outline the parameters for the part of the monitoring program that is performed by sampling and testing air, soil I sediment, and water quality, and also measures noise levels and any other pertinent ambient parameters, if needed. Its estimated cost considering that some activities will be carried out (i) before construction (project baseline environmental conditions), (ii) during construction (assumed to take five years), and (iii) during the first year of operation. Detailed monitoring programs will be prepared during the detailed design stage. The estimated cost for monitoring forms part of the EMP costs; the costs for sampling and laboratory testing will be included in the CSCs' contracts. Many of the parameters listed below are required by Vietnamese regulations and would need to be done even if they are not directly related to expected project impacts.

Total Total

(VND) (USD)

30,240,000 1,475.12

The Project Management Unit (PMU-MOC) in the Ministry of Construction (MoC) will be responsible for the overall consolidated monitoring and quality assurance of the Project. While Cities are responsible for EMP implementation, the PMU-MOC will have a quality assurance and monitoring role including all safeguards aspects. The Cities will submit all safeguards progress and monitoring reports to the PMU-MOC. The MoC will also be responsible for contracting and managing the Independent Environmental Monitoring Consultant (IEMC) who will monitor the environmental performance in all six project cities. The IEMC's costs are therefore part of the MoC budget, and not do not form part of the cities' EMP implementation costs. The figure and subsequent table below summarize the roles and responsibilities of the key parties and their relationships with regard to the implementation of the EMP. The roles and responsibilities of the ESU, PPMUs, CSC, and IEMC are outlined below:

• Contractors have the main responsibility for implementing mitigation measures. Those measures will be included in the bidding documents and the costs are to be included in their bids and the construction contracts.

• CSC is responsible for supervising and monitoring the day-to-day implementation of mitigation measures. The associated costs are included in CSC service contracts.

• IEMC will be responsible for environmental monitoring which includes (i) support to the ESUIPPMU for implementing supervision and monitoring, and (ii) reporting on the implementation through periodic monitoring reports.

50

Table 11: Roles and responsibilities of key parties (Description referred to Figure 3)

Links Description of Roles and Responsibilities

la Based on quarterly reports of IEMC, PMU-MOC is responsible for preparing periodic reports to i submit to the WB.

Ib PMU-MOC send a notice to PPMU on working plan of IEMC, receive reports of lEMC and monitoring the implementation of agreed proposals and monitor the sending of the monthly report from the Safety policy officer to the PPMU

Ic PMU-MOC with the assistance of contracted lEMC, provide the guideline to and monitor the implementation ofPPMU's EMP,

(2a) PPMU assigns the safeguard staff (ESU) to review and check the environment-related sections in of the bidding and contract documents for appropriate items, such as the ECOPs, to ensure compliance with EMP

PPMU assigns the safeguards staff (ESU) to supervise, manage and carry out EMP activities and also assigns CSC to closely supervise and monitor safeguard performance of the contractor, including implementing the environmental monitoring program.

PPMUIESU establishes a hotline communication with the local community to be responsive to the complaints, comments, and/or recommendations from local people and the public throughout the site clearance and construction period.

(2b) Based on quarterly reports oflEMC, PPMU is responsible for preparing periodic reports to submit to the Provincial DONRE.

(2c) lEMC contracted by PMU-MOC supports PPMUIESU to implement the EMP in line with Government's environmental regulations as well as the WB safeguard policies. In consultation with DONREs, lEMC will establish a specific environmental monitoring program for the project to be implemented by CSC at key locations as shown in the detailed design documents.

51

(3 a) Contractor: Before construction, with general guideline from IEMC, prepares a site-specific environment management plan (SEMP) during site clearance and construction process as part of their construction method statement, then submit it to CSC and/or PPMU for review and approval; During construction, the contractor has to submit a monthly report on safeguard issues, mitigation, and results throughout the construction period. In case of unexpected problem, the contractor will consult CSCIPPMU.

PPMU/CSC: Reviews the SEMP and can propose change as deemed necessary to be in line with the contractual obligations as well as appropriate to each specific site. Daily supervision and monitoring of contractor's safeguard performance will be responsibility of the CSC.

(3b) CSC submits periodic monitoring reports of environmental mitigation measures to PPMU; recommends to the PPMU to suspend, in part or completely, construction work if it does not meet labor safety or environmental protection requirements of the contract.

PPMU reviews CSC's periodic reports to monitor compliance with mitigation measures.

(3c) Community: According to Vietnamese practice, the community has the right and responsibility to routinely monitor environmental performance during construction to ensure that their rights and safety are adequately protected and that the mitigation measures are effectively implemented by contractors and/or PPMU. In case of unexpected problems, they will report to CSCIPPMU and/or call the hotline.

PPMU: Encourage, support and create good conditions for local community to participate in the environmental supervision and monitoring activities. PPMU/CSC will review and response to the requests and/or recommendations made by community to ensure that the potential negative impacts are adequately mitigated.

(4a) Contractor: Carries out the EMP as required during site clearance and construction, including conduct self-monitoring and submission of report.

IEMC: periodically supervises and monitors the overall project EMP implementation including provision of safeguard training to PPMUIESU staff, community, CSC, and contractors as needed. The training will be designed· to enhance the effectiveness of the EMP implementation and reporting.

(4b) Community: Support and collaborate with IEMC during periodic monitoring and provide inputs to the overall safeguard issues that require attention and/or mitigation.

IEMC: Strengthen local community's capacity and relevant agencies through preparation of relevant documents necessary for monitoring, supervision, and reporting including preparation of a database for the activities.

IEMC: assist PPMU and communities for the implementation of Information-Education­Communication (1EC) activities within Component 4 with regard to environmental hygiene, sanitation, road safety, etc.

(4c) CSC: Supports and colIaborates with IEMC to establish, collect and highlight information about essential environmental parameters in the field, and information for construction implementation.

IEMC: Monitors the implementation of the EMP every 3 months including submission of the field report. Creates database of results from environmental supervision and monitoring and training PPMU in use of such a database:

IEMC: Coordinates with CSC for carrying out the monitoring activities and the preparing the safeguard reports on EMP performance; enhances the capacity of CSC staff through training programs in environmental supervision.

5.3.2. Specific Responsibilities ofPMU, CSC, and IEMC

City-level Project Management Units (PPMUs)

1. PPMUs are responsible for implementing the EMP during the detailed design and construction stages. EMP implementation during operation stage is the responsibility of the facilities' operators at the city level. PPMU will set up an Environmental and Social Unit (ESU) to ensure timely and effective implementation of the EMP, including preparation of reports on safeguard compliance as required by Government and WB.

PPMUIESUs are responsible for ensuring that the relevant sections in the bidding and contract documents for all construction works are in compliance with the EMP; this means they contain the requirements of the ECOPs and site-specific EMPs.

PPMUIESUs are responsible for communicating with relevant local, provincial and national departments; and with the agencies responsible for implementing and supervising EMP, especially with the provincial Department of Natural Resources and Environment (DONRE), and with the concerned wards/communes during planning, monitoring, management and operation.

PPMUIESUs will coordinate with community organizations to encourage them to actively participate in the planning, management, and implementation of the project, including monitoring of the contractor's performance.

To ensure effective monitoring and timely implementation of the EMP, PPMUIESUs will hire national environmental consultants to assist them with carrying out and monitoring the EMP implementation. Responsibilities of the Independent Environmental Monitoring Consultant (IEMC) are described further below.

- In the course of supervising and monitoring the contractors' perfonnance, PPMUs will be responsible for: (a) checking project implementation indicators relating to the environment; (b) conducting unscheduled, surprise inspections to ensure that mitigation measures are being implemented as required in construction contract by contractor; (c) reviewing the periodic reports of the construction supervision consultant (CSC) to ensure compliance with mitigation measures and EMPs; and (d) based on the periodic reports by CSC and IEMC, preparation of reports on environmental compliance of subprojects, to be submitted to WB and DONRE (this will be part of the submission of progress report to WB every six months).

PPMUs will coordinate closely with relevant city enterprises for water supply, environmental sanitation, and solid waste collection, to monitor their operation and maintenance activities during project implementation.

Construction Supervision Consultant (CSC)

The CSC is responsible for monitoring the safeguard perfonnance of the contractors during site clearance and construction, including oversight of the self-monitoring to be conducted by contractor. With regard to environmental safeguards, the CSC's main responsibility will include, but not be limited to, the following:

- Assist IEMC to establish, collect and provide infonnation essential environmental indicators, on-site and for the construction works.

- Ensure that all work comply with the approved EMPs, relevant enevironmental standards and codes of practice (ECOPs), as set out in docwnents for environmental impact mitigation and monitoring.

- Monitor the implementation of mitigation measures by the contractors, propose and deploy any necessary supplementary measures in time to improve mitigation measures to fully meet the environmental management and safety requirements of project.

- Prepare action plans and/or propose urgent solutions to cope with environmental problems, emergency situations and damage that occurred during construction

- Recommend to PPMUs to suspend partially or completely construction work if labor safety and environmental protection requirements of the contract are not being complied with.

- Organize regular discussions with relevant parties, agencies and other stakeholders to provide infonnation about implementation plans to increase people's awareness of the need for environmental protection and management during construction process.

Construction Contractor

The construction contractor's responsibilities with respect to all aspects of the works, including the environmental aspects, are set out in the contract docwnents, signed with the PPMU.

Construction contractors are responsible for carrying out environmental impact mitigation measures and for complying with the approved EMP when implementing construction contracts. When preparing the "technical method statement", the contractor will study the project's approved EIA report and propose a construction method that includes environmental mitigation and monitoring measures that are in line with the approved EMP.

55

- Contractor's method statement will be submitted to PPMUs and CSC for review, as well as to IEMC, as deemed necessary. Changes, if any, will be evaluated for their feasibility and for legal issues (laws, decrees, circulars and other regulations) before suitable adjustments are approved for specific cases on-site.

During the construction work, the construction contractors will be closely supervised by PPMUs, CSC, IEMC, environmental authorities and the local community for their compliance with the EMP.

Independent Environmental Monitoring Consultant (IEMC)

The IEMC will be responsible for assisting the PPMU with the EMP implementation. This also includes advising the CSC, contractors and communities on environmental compliance, and on carrying out the monitoring program in accordance with regulations, procedures and policies of the Government and the WB, respectively. After the detailed implementation of the environmental monitoring programs was discussed by the city-level PPMU and World Bank supervision staff, the IEMC will be responsible for quarterly checking, and for supporting the PPMU staff to supervise overall project activities to ensure that uniform environmental policies of the Government and World Bank are applied and supervised during project implementation. The IEMC will be responsible for: (1) providing training and capacity building for construction management PPMUIESU staff, including field engineers and/or consultants (CSC), in supervising the EMP implementation by the contractors; (2) ensuring active participation of the local communities and schools in the project areas, (3) monitoring of environmental parameters to assess the overall impacts of the project, and (4) establish the environmental training program that is part of Component 4.

Specifically, the IEMC's responsibilities include:

- Ensuring that the approved EMP and all other relevant project legal agreements related to environmental safeguards are fully applied and complied with during project implementation.

- Assessing the effectiveness of mitigation measures which are applied by contractors and CSC during project implementation; providing proposals and recommendations to the PPMUs on improvements needed to meet the safeguard requirements.

- Reporting periodically (every 3 months) to the PPMUs on actual EMP performance during project implementation.

- Establishing standard procedures, methods and forms to assist the PPMUs and CSC to assess contractors' progress in implementing the required impact mitigation and monitoring measures.

- Assisting the PPMUs' environmental staff to review and check that relevant environmental sections (based on the ECOPs) have been included in the bid packages and concstruction contract documents to ensure compliance with environmental policies and impact mitigation and monitoring requirements.

- Measuring, taking samples and monitoring periodically the key environmental parameters, i.e. once every 3 months.

- Assistance with the preparation of documents and implementation of training programs in environmental monitoring and supervision for contractors, CSC and relevant staff of the PPMU s (environmental staff and coordinators of contract packages).

Via PPMUs, discussing with relevant enterprises, as necessary, to find suitable solutions for unexpected risks relating to environmental sanitation.

56

7.3.3. Reporting Arrangements

The PPMU will prepare reports twice per year for submission to the World Bank including the compliance with the EMP. The report will contain the monitoring results and assessments of the IEMC that show project progress and the status of implementation of the EMP. The reports will cover, among other matters as appropriate, the following:

- Contractor's compliance with mitigation measures

- Wastewater and environmental sanitation issues

- Existing flooding situation, where relevant

- Traffic congestion or disruption

- Performance of the water supply systems

- Quality of wastewater-receiving water bodies

- Potential project-related risks and risk management issues

- Quality of water in rivers (fien, Hau, 0 Mon and Binh Thuy), canals (Ngong, Sao and canal at the south of Bun Xang lake) and Bun Xang lake

- Status of measures to assist project-affected people at the new resettlement sites on environmental aspects

- Consultation with local communities in key project areas

5.4. Capacity Building Program

5.4.1. Technical Assistance support for the implementation of safeguards

An assessment of safeguards implementation capacity of existing PPMU staff indicates that PPMU staffs have limited knowledge on WB safeguard requirements as well as limited knowledge of environment and social issues. Such lack of capacity represents a risk to project implementation of safeguards requirements contained in the EMP and, as required by the WB policy, is to be addressed through capacity building. Therefore it is proposed to provide capacity building through technical assistance that will support the PMU during the implementation of the safeguards requirements. The technical assistance will provide the necessary technical support the PPMU in its work with contractors as well as other entities involved in the implementation of the EMP.

The scope of the technical assistance would cover support from experts and training that would cover both the knowledge on safeguards requirements and procedures for the project as well as training that covers both specific knowledge on safeguard procedures and requirement for the project staff, consultants, and national contractor would be important. This would include, for example, assistance in the preparation of documents and implementation of training program on environmental management and environmental monitoring for contractors, CSC and relevant staffs of PPMU (environmental staffs and coordinators of packages) to do their tasks. It would also include assisting the PPMU's environmental staffs with the review of contract documents on the bidding packages for construction items of the project to ensure compliance with environmental protection policies and impact mitigation and monitoring requirements as well as provide general environmental guidance as requested by the PPMU to enhance overall project implementation and performance.

Given the nature, locations, and scale of construction, it is anticipated that the safeguard technical assistance support and training will be provided at least during the first 3 years of the project implementation. The WB safeguard specialists will participate in the capacity building in particular in the training activities as appropriate.

5.4.2. Training programs proposed

Table 11 below provides examples of the basic trainings for safeguards during project implementation. The training programs will be developed and delivered by the Technical Assistance team for the implementation of safeguards for the PPMU training. The PPMUIIEMe with the support of the Technical Assistance team for the implementation of safeguards will provide the training to contractors, esc and other groups.

Other more specific and tailored training will be developed and agreed upon between PMU, IEMe and the Technical Assistance team for the implementation of safeguards during project implementation based upon a reassessment of needs and the status of safeguards implementation.

- Target groups for the training: include PPMU staff, ESU staff, field engineers, esc, construction contractors, local authorities and community representatives in the project area. Training of workers and drivers is the responsibility of the contractor.

- Training schedule: At least 1 month before the construction of the first contract. The training can be adjusted in line with the implementation schedule of the subproject/contracts.

- Training frequency: The basic training programs proposed in table 12 will take place every six months on a yearly basis and its content updated and adapted to implementation issues. Training frequency and content will be reassessed during implementation depending on needs. It is foreseen that the training program for PPMU staff will continue until year three of implementation. Three days of training for esc and contractors are also planned to take place twice a year on an annual basis for at least two years.

59

safeguard management costs, including technical assistance support for the implementation of safeguards and training. They exclude all resettlement cost and all costs for independent monitoring of the RP and EMDP implementation.

Costs for the implementation of the mitigation measures during construction will be part of the contract costs while the costs for the supervision and monitoring of all construction contractors by the CSC is provided for in the construction supervision contracts. Costs for PPMU operations related to EMP are provided for in the project management budget of the PPMU, including basic safeguards training and allowances for all staff who participate in the monitoring program. After project completion, the cost for environmental monitoring of the constructed facilities will be funded by the cities' operations and maintenance budgets.

The participation of community representatives in EMP implementation is voluntary, and without salary. Hence, to encourage the participation of community members, the cost for materials, equipment used for monitoring and rewards for people who are voted to implement monitoring are taken into account.

The table below shows the sources of funding for the EMP implementation, including the environmental quality monitoring program.

ANNEX 2: Guidelines for the Preparation of a Dredged Materials Management Plan (DMMP) for Contaminated Sludge

To ensure that dredging, transportation, and disposal of contaminated sludge will not create adverse impacts on local residents and the environment, a guideline for the preparation of a DMMP is provided below. If during the environmental assessment stage, contaminated material is identified in the water body to be excavated, the detailed design will include a comprehensive testing program and the development of a DMMP, reflecting the guidelines below. The detailed DMMP shall be prepared by the contractor in consultation with the PMU and the World Bank: prior to commencement of civil works.

The main environmental and social issues related to contaminated dredged materials are: (a) pollution during the transport of the dredged materials from the dredging site to the disposal area; (b) potential increase in turbidity and pollution of the ambient water in the lakes/canals during dredging; (c) odors and other nuisance to local residents; and (d) potential improper use of contaminated sludge for public infrastructure works or in residential areas. To facilitate the preparation of a DMMP given that the activities will be carried out in an urban area and/or in an existing water body that may be used by other water users, the following important aspects must be considered:

• Assess the quality of the sediments. This assessment mustbe carried out to confirm that the sediments do not include large amounts of environmentally harmful materials, such as heavy metals and/or other toxic substances. If the materials are found to be above the thresholds for heavy metals or toxic substances stipulated by the national standards, a special disposal plan should be prepared, together with a monitoring plan. The special disposal plan should also include a program to protect the residents in nearby communities from using the dredged materials for house construction or gardening. The bottom sediment/sludge samples will be analysed for key pollutants according to the Vietnamese national standards. The sampling and analytical methods should be in line with the Go V regulations while the number of sampling locations will depend on the risk levels for each specific site. The number of samples to be analysed will be determined by the proposed volume of dredging as follows:

Volume of Dredged Material in m3 No. of Sediment Samples

IUp to 25,000 3

~5,000 to 100,000 4-6

100,000 to 500,000 6-10

500,000 to 2,000,000 10-20

For each 1,000,000 above 2,000,000 Additional 10

• Identify the land available for the disposal of the dredged materials. The DMMP should identify the landfill sites andlor land that would be suitable for the disposal of dredged materials in line with the level of risks associated with it. Public land, land for construction of rural roads or other public works, or private land, may be used, if the affected landowners agree. If the risks due to contamination of the sludge are high, the sludge must be disposed of at sanitary landfills.

• Prepare a dredging and transport plan. The dredging procedures and transport plan will outline the following: (a) dredging methods (pipeline, water pumping before digging, etc.), mode of transport to the disposal areas andlor temporary storage sites. If trucks are used, indicate proposed transport routes from the dredging site to the disposal area, (b) time and hours of operation, (c) types of barges or vehicles/trucks and proposed measures to reduce the leakage of the dredged materials from the transport trucks, (d) contractors' responsibilities for cleaning the roads and carry out remedial works if necessary, and (e) a communication plan for the nearby communities, including contact numbers for lodging complaints.

• Temporary storage/disposal for uncontaminated sediment/mud The dredged materials are in a mud-like state before settling for 24 - 48 hours. All drainage water from the temporary storage on land shall be discharged back to the canaInakes. For highly contaminated sludge, or sludge containing organic materials that generate strong odors, the dredged materials should be hauled by closed tanker trucks away from the construction site as soon as possible. For bottom sediments with a low content organic materials, the dredged sediments will be transported to a containment area which is appropriately located and properly designed and of an adequate size. A monitoring plan for tracking the disposal of highly contaminated materials, if any are present, will also be prepared.

• Identify key areas and/or facilities (businesses, schools, public services, etc.) that are sensitive to dredging and transport of dredged materials. The DMMP shall include an inventory / analysis of the potentially affected local businesses, access to water, and transport due to the dredging operations, and provide a plan to mitigate andlor compensate for the disturbances. The plan should include all measures necessary to avoid impacts on local transportation and water supply, and access to local residents as much as possible.

• Identify other water users. In areas where dredging may cause negative impacts to these water users, the respective subproject owner is required to inform/consult them and develop a series of actions to address their concerns, including water quality monitoring intheDMMP.
