Objectives of the Environmental Assessment (EA) Report * The objectives of the draft EA Report are to assess the potential environmental impacts of activities proposed in Phase 1 investment activities of the Dong Hoi City Sub-project under the Coastal Cities Environmental Sanitation Project (CCESP) and recommended needed mitigation and monitoring measures to address such impacts. Based on the Pre-Feasibility Study (Pre-FS) and CIP prepared for the sub-project, the draft EA was prepared to meet the requirements of both the Government of Vietnam (GoV) and the World Bank as part of the project preparation process. Potential social impacts of proposed Phase 1 activities are assessed in the separately submitted Resettlement Plan. | Safeguard Policies of the World Bank: In addition to procedures of environmental review and approval of the GoV, the CCESP shall be prepared and implemented in compliance with | environmental and social safeguard policies of the World Bank. Based on these safeguard policies, 3 the CCESP has been classified as a Category A type project due to the potential to cause significant environmental impact if proper assessment and mitigation measures are not applied. Specific Bank safeguard policies that were assessed during the EA study were: | . Environmental Assessment - Operational Procedure / Bank Procedure 4.01 (OP /BP 4.01) 1 * Natural Habitats (OP 4.04) . Cultural Resources (draft OP 4.11 - OPN 11.03) Public Consultations: As a Category A type project, two (2) stages of public consultations were | carried out and documented in accordance with OP 4.01. A first stage of consultations was held in September - October 2005, involving focus group discussions and household surveys of some 300 I households. A second stage of consultations was conducted on December 27, 2005 and involved 20 participants. This second stage of consultations was supplemented by a written questionnaire survey conducted on February 25, 2006 involving 20 ho.useholds residing near the proposed Phase 1 discharge outlets. Public Disclosure: As a Category A project, completed EAs must be available made to the public in | accordance with BP 17.50. The draft EA was disclosed in Washington DC and the Vietnam Development Information Center (VIDC) in Hanoi on January 19, 2006. The Vietnamese translations I of Executive Summary were disclosed by January 13, 2006. All documents were disclosed locally by the Provincial People's Committee (PCC), the provincial Department of Natural Resources and Environment (DONRE), the Project Preparation Units (PPUs), offices of the Wards in which people will be affected by the project, and were accessible to local NGOs and project affected people (PAPs). I I Final Environmental Assessment Executive Summary ES-i Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City 2. PROJECT OUTLINE 2.1. Project's Objectives Project's objectives in Phase 1: Objectives of the Phase 1 activities in Dong Hoi are as follows: Mitigate flooding and improve environment conditions in the City Center; . Initiate a revolving fund for the improvement cf household sanitation; and . Strengthen the capability of the Project Management Unit (PMU). 2.2. Description of Proposed Project Components Phase 1 (scheduled from 2007 to 2011) of the Dong Hoi sub-project will focus on the following mai components and investment items: Component 1: Drainage, Flood Control & Wastewater Collection - involving rehabilitation and improvement of some 22 km of existing pipes and drainage systems, rehabilitation of some 3.8 km of embankment along the Cau Rao River, Phong Thuy Channel and Nam Ly Pond, involving the dredging some 183,896 m3 of materials from these waterways to restore their drainage capacity. Component 4: Resettlement - involving compensation of the 47 project affected households currently residing along the waterways and embankments that will be rehabilitated under Component 1. Supporting components include Component 5 (sanitation revolving fund) and Ccmponent 6 (Capacity Building and Implementation Support). Phase 2 (scheduled from 2008 to 2013): In addition to continuation of the Phase 1, the proposed Phase 2 investments will include construction of the wastewater treatment plant (WWTP) for the city. 3. Summary of Existing Environmental and Socio-economic Conditions Based on available reports of the Quang Binh DONRE, current air and water quality in the city's urban environment generally meet national standards. A noted exception is the apparently increasing levels I of coliform bacteria to levels which are generally above national standards. According to 300 respondents to the socio-economic survey conducted as part of the EA, the most serious environmental issue in their area was the lack of sewage and drainage system and the second most serious issue was flooding. Illnesses related to poor environmental sanitation conditions, such as diarrhea and dysentery, are common and apparently increasing in frequency. In the household survey, 60 % of respondents reported that household members had been sick during the previous month from an environment-related illness. 3 According to the local authorities, the Loc Ninh dumpsite located about 8 km from the City center has been listed by the government as being in serious violation of environmental regulations and is planned to be closed. This dumpsite covers some 13 ha and has been operational since 1995. The wastes deposited at this dumpslte are not levelled or well covered, and generated leachate is not properly I collected and treated. As a result, the leachate flows directly to nearby surface and ground waters, | polluting these water sources. Groundwater from a tested well showed a serious level of pollution that is 3 attributed to these uncontrolled and untreated leachate discharges. Based on thq results of a Due | Diligence Review conducted as part of the EA process, the on-going Dong Hoi Urban Development 1 Project (DUDP) will not have adequate budget remaining to fund the proper closure of Loc Ninh dumpsite contrary to previous expectations. I. Final Environmental Assessment Executive Summary ES-2 Coastal Cities Environimental Sanitation Project (CCESP) Dong I loi City 4. FORECAST AND ASSESSMENT OF PREDICTED ENVIRONMENTAL IMPACTS 4.1. Summary of Predicted Impacts Based on completed studies and local consultations, the sub-project is expected to have significant positive benefits for the environment, public health and the tourism-based economy due to reduced frequency and level of flooding in the City's urban center, improved collection and handling of liquid and solid wastes, and supportive improvements in sanitation service and capacity. Five (5) key sources of potentially adverse environmental impacts were identified during the EA study: J (1) Impact of the construction work; I (2) Discharge of untreated wastewater effluents from 3 outlets at the Nhat Le and Cau Rao Rivers and the Phong Thuy Channel (3) Transport and disposal of dredged sediment | (4) Impacts of mine and unexploded ordinance removal (5) Potential cultural impacts to the 200 year old Binh Quan Citadel (6) Impact of Retaining Septic Tanks 4.2 Impacts of Construction Work I The construction works for upgrading drainage and combined sewer systems will involve two catchment areas of Dong Hoi City. Potential sources of environmental impact will include some 3.08 3 km street excavations and an estimated 13,270 m3 .of excavated soil. These excavated materials will consist largely of sand which will be directly re-used on-site for back-filling excavated pipeline 3 trenches once installation has been completed. The draft EA also provides an assessment and mitigation measures for the following common types of construction impacts: * Dust, noise and air pollution from excavations, levelling and construction vehiicles I . * Domestic wastes generated during construction . Leakage of residual grease and oil 3 . Impacts to traffic 4.3 Discharge of Untreated Wastewater Effluents from New Household Connections The untreated wastewater discharges of new household connections made to the combined sewer | systems before WWTP are completed in Phase 2 would increase pollution loads and concentrations 3 in the receiving water bodies. Based on the Construction Investment Project (CIP), 85% of the households in wards of Dong My and Hai Dinh are expected to be connected during Phase 1, or a the total of some 1,258 households (estimated 5,032 people). This compares to some 2,128 people (about 532 households) that are reportedly connected now. 3 The four (4) combined sewer outlet areas that would be directly impacted in the Dong My Ward are Catchments Discharge Outlet Phan Boi Chau street Phong Thuy Channel Nguyen Du street: Nhat Le River (3 outlets - Le Qui Don, Han lMAac Tu & Ba Huyen Thanh Quan) The five (5) combined sewer outlet areas that would be directly impacted in the Hai Dinh Ward are Catchments Drainage Outlet 3 DONRE Hao Thanh Final Environmental Assessment Executive Summary ES-3 U Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Hung Vuong Hao Thanh Nguyen Trai Street Nhat Le River Nguyen Viet Xuan street Nhat Le Thach Han Street Nhat Le I Based on the CIP for Phase 1, the domestic waste water from Dong Hoi City will be discharged through aseries of nine (9) outlets, which are located close to each to other along a short segment of 3 Nhat Le River from the Cultural House in Dong My ward to the confluence of Nhat Le and Cau Rao Rivers (including the confluence area). This large estuary - river mouth area represents the receiving water body for the outlet discharges during Phase 1. It is necessary to note that this water body | receives fresh water with high flow rate from upstream and also has high level of tidal exchange with the sea. Due to this high water exchange / flow rate and the close proximity of the nine outlets, the estimated pollution load and predicted change in pollution concentrations is calculated as a single value for the preliminary assessment (Tables ES - 1 and ES - 2).

The model makes certain assumptions. These assumptions and their limitations where the results are concerned are discussed in Section 6.2 Details of the model and results are in Annex 2. These concentrations were used in a model to predict the pollution level near the outlets. 1her-e will be an increase but not significant compared to the existing pollution situation. The concentration of | coliform, and COD near by the outlets in Nhat le River will be higher than allowed by national standards but these pollution concentrations are quickly reduced further from the outlets. Based on the above calculations, the predicted concentrations for coliform will meet national standard within 90 m downstream of the outlets. These predictions are based on the assumption that all discharges will be made from just one outlet (due to the close proximity of the 9 outlets). If we could calculate the discharge impact of each outlet, it is predicted that the pollution concentrations would be more dispersed 3 and impacted areas (decay distances to met national standards) may be closer to each outlet. The sample taken from the site near by the outlet in Phong Thuy Chanel (see Station Ti in Annex 2.2) also showed that the COD and coliform parameters are much higher than allowed by national standards. The poor water quality of this constructed channel is visible with the black-gray color of wastewater near the outlets. Additional discharges to this Channel from Outlets 1 and 6 are not recommended due to the existing poor water quality in the channel and the significantly reduced dilution and dispersion capacity. The most effective impact mitigation measure is to postpone the household connections until thle WWTPs are operational or advance the schedule for constructing WWTPs to provide treatment earlier in the project period so that these project components are more closely linked. However, if it is agreed and locally approved to allow household connections to the combined sewer system prior to completion of the WWTPs, mitigation measures for "end of the pipe" treatments to reduce impacts and potential health risks are available and described. 4.3.5 Impact from Septic Tanks The question of whether to retain the septic tanks after the house connections are made is still unanswered. The prefeasibility study done by the National Consultant states that most of the septic tanks are either leaking or not functioning properly. If the septic tanks are retained then test should confirm that all are watertight and will remain so for the life of the project. 4.4 Impacts of Excavation, Transport and Disposal of Dredged Sediments and Septage Based on the sub-project CIP, the proposed areas and volumes of dredging activities are: Cau Rao River (138,800 m3), Phong Thuy Channel (23,900 M3 ) and Nam Ly Lake (20,598,m ). Key impact 3 concerns of these proposed activities include potential impacts to existing aquatic ecology, air quality and safety; transport, and disposal. Based on completed sediment testing results, the sediments to be dredged consist primarily of organic matter and can be used or disposed without special treatment Expected uses of the dredge sediment include agricultural and landscaping uses. To improve handling and reduce volume and weight (by about 50%) of sediments needing to be transported, it is Final Envir-onmental Assessment Executive Summary ES-5 lI Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City recommended that "de-watering" and partial drying will be conducted along the river banks where dredging is conducted. It is estimated that a drying area 20 m by 1,770 m along Cau Rao River and 8 m by 1,000 m long along Phong Thuy Channel may be needed for this recommended sludge de- watering to be conducted during the dry season to be effective. Based on recent site surveys, open areas for such sludge drying are available near the dredging sites. 4.5 Impact of Mine and Unexploded Ordinance Removal The potential presence of unexploded mines and ordinance is a recognized impact issue in the Dong Hoi area. Local concerns for potential impacts to residents and work crews during construction included areas to be excavated under the city streets and areas to be dredged. Within the CIP cost estimates, budgets are provided for de-mining operations of proposed project sites. To minimize potential impacts, these activities will need to be well coordinated with concerned agencies and capable sub-contractors well in advance of proposed work schedules. 4.6 Summary of Predicted Impacts on Natural Habitats (OP 4.04) The proposed sub-project area primarily involves urban or sub-urban areas of Dong Hoi City. Non- urban lands in the area are widely used for farming and tree plantations. The nearby coastal areas largely consist of sandy beaches and offshore slopes. The natural lakes which are present in near the project area serve as part of the City's drainage an-d wastewater discharge system. Coral reefs and mangroves are not common in the coastal area. Quang Binh is located within the biological zone of north Truong Son which has a recognized high level of biodiversity and endemic species, particularly in the Karst Phong Nha- Ke Bang National Park, which is a UNESCO World Heritage Site. This unique national park is located some 30 - 50 km inland from Dong Hoi and the project investments are expected to benefit visitors to this protected area. 4.7 Summary of Predicetd Impacts on Cultural Resources (OP 4.11) Based on site surveys and local consultations, the proposed sub-project sites do not include any known physical cultural resources, with the noted exception of the 200 year old Binh Dinh Citadel. Proposed drainage works in the Citadel area are located more then 150 meters away from this historic structure which is currently being renovated by the Department of Culture and Information, including similar types of drainage improvements to help protect this building from floods. The cultural history of the general area is significant. As result, special attention will need to be given during proposed excavation and dredging activities for possible discovery of cultural or historical artifacts. Provisions for reporting any discoveries during excavation or dredging works are provided in the proposed SOPs of the Contract Documents. 5.0 ENVIRONMENTAL MANAGEMENT PLAN (EMP) In accordance with the Bank's OP 4.01, the draft EA provides an environmental management plan (EMP) which is designed to: (a) Identify the set responses to potentially adverse impacts; (b) Determine requirements for ensuring that those responses are made effectively; and (c) Describe the means for meeting those requirements. 5.1 Mitigation Measures Final Environmental Assessment Executive Summary ES-6 3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Based on the predicted Phase 1 environmental Impacts, appropriate mitigation measures are identified and described for each of the key project stages and types of impacts, including: 3 Mitigation Measures during Detailed Design, including general design considerations; design of drainage and sewerage systems; design of solid waste transfer stations: | Mitigation Measures during Construction, including specific mitigation measures during excavation and dredging activities; 3 Mitigation Measures During Operation, including drainage and sewerage systems, solid waste transfer station: environmental mitigation measures for resettlement sites l Septic tanks: The majority of the septic tanks are either poorly designed, leaking, in need of major repairs or not functioning properly. If any is retained in service the long term integrity should be convincingly established by appropriate tests. This will be difficult, expensive and inconvenient. (Septic tanks are * usually tested before placing in service). They will serve no useful purpose after the house 3 connections are installed. They should be abandoned completely at the same time the house connections are made. l Il I I l I I' II l Final Environmental Assessment Executive Summary ES-7 - - -- m~ - - - - - e- m-~~~ - Dong I loi City Coastal Cities Environmental Sanitation Project (CUEtH) discharge - Dong Hoi city Table ES - 3 Summary of environmental impacts and mitigations for temporary Outlet 2,3,4,5,7,8,9 Outlet 1,6 Nhat Le River Description of Receiving body Phong Thuy Channel - Hydrology regime of Nhat Le river is affected by tide regime.

Overall regulatory monitoring of the project. A set of monitoring indicators is proposed to assess the implementation at various project stages. These performance monitoring indicators will be agreed in the final EA report, EMP and Project Implementation Plan (PIP) as well as the findings and recommendations of the Independent Safeguards Monitoring (ISM) Consultant to be appointed under the project. The PMU will prepare for the Bank bi-annual performance monitoring reports, which will detail project progress with respect to agreed targets for the environmental performance indicators. 5.3 Project Organization for Environmental Management System The draft EA recommends an organizational and systematic approach towards an environmental management system involving the following key project stakeholders and responsiblities: Project Management Unit (PMU): The PMU has the overall responsibility to implement and monitor the EMP. Assisted by the ISM anbd CMC consultants, the PMU will moniitor and report on the implementation of mitigation measures during the constrctor's construction works. The proposed PMU staffing organization will include at least one environmental mitigation and monitoring specialist. Community Representatives: At the sub-project's teriary and household connection levels, community representatives will be encouraged to monitor the environmental sanitation conditions in their areas. Construction Management Consultant (CMC): The main tasks of CMC are monitoring basic construction practices and procedures, including Standfard Operating Procedures (SOPs) for mitigating environmental impacts as described in the draft EA. Independent Safeguards Monitoring (ISM) Consultant: The ISM will be responsible for monitoring EMP implementation activities and ensuring that agreed environmental and social safeguard policies oif the GoV and the Bank are applied and monitored. 5.4 Capacity Development and Training Needed training on how to implement effective environmental monitoring, mitigation and reporting measures and systems will be provided to key stakeholders (PMU, contractors and commurnity representatives) based on the actual project needs, roles and responsibilities.

The CCESP builds on recent and on-going projects of the Bank's urban sector portfolio in Vietnam, including the on-going Three Cities Sanitation Project (Loan No. 3211 - VN) and previously completed Ho Chi Minh City Sanitation Project and Urban Upgrading Project. As an initial step to help improve sanitation and control pollution in smaller coastal cities, the GoV selected the three cities of Nha Trang (Khanh Hoa Province), Quy Nhon (Binh Dinh Province) and Dong Hoi (Quang Binh Province) to participate in the proposed CCESP, the general locations of which are shown in Figure I -1.1. These three cities of central Vietnam were selected because they are currently experiencing higher than average rates of population growth and economic development, and a recognized need for environmental sanitation investments that are beyond the present resources of the national and local governments to address in the near future. Within the three targeted urban areas, the primary environmental sanitation objectives of the CCESP project are to help: 3. Reduce the incidence of flooding; 3 . Separate wastewater and storm drainage collection systems, . Construct new wastewater collection, pumping and treatment system and facilities; . 3 * Improve the collection and ensuring the safe disposal of solid waste; Establish new and better designed landfill sites . Strengthen the capacity of the urban environmental companies (URENCO) in each of the three cities to sustain the improvements made.

To meet these objectives, the CCESP will support six (6) components, namely: * Component 1: Drainage and wastewater . * Component 2: Wastewater treatment 3 * Component 3: Solid waste management * Component 4: Resettlement 3 * Component 5: Sanitation revolving fund Component 6: Capacity building and implementation support In May 2005, a consultancy contract was signed with the Vietnamese National Consultants - Vietnam Water Supply and Sewerage Consultant Company (VIWASE) for a part of Phase 1 work and on August 2, 2005, a similar contract was signed with The Louis Berger Group - The Nippon Koei (LBG- NK) association to do other work related to Phase 1 preparation. Prior to this, separate specialist studies in solid waste and wastewater treatment options were funded by Dutch government, World Bank and US Agency for International Development (USAID) to investigate treatment and disposal choices and to advise the National Consultant before and during the preparation of the Pre-FS, which was completed in February 2005. More recently, the World Bank (WB), on behalf of the Governelnt of Vietnam (GOV), secured Japanese grant funding (PHRD Grant) to support preparation of the two CCESP phases. Purpose and Objective of the Environmental Assessment (EA): This EA has been designed to meet the concurrent requirements of the World Bank, the GoV and the Province of Quang Binh to properly assess potential environmental impacts as a basic part of the project preparation cycle and to provide specific guidance on measures needed to mitigate, manage and monitor potential environmental impacts during project implementation and operation. In addition to avoiding or minimizing impacts from the planning stage, the objective of the EA study and document is to help improve overall performance and benefits of the project if it is implemented. In general, social impacts are separately addressed and assessed in specific cases where Resettlement Action Plans (RAPs) are required. Summary Description of Phase 1 of the Proposed Sub-Project In summary, the objectives of the Dong Hoi City Sub-project, Phase 1 are to: . * Mitigate flooding and improve environment in the City center; * Initiate a revolving fund for the improvement of household sanitation; and .* Strengthen the capability of the Project Management Unit (PMU).

It is an attraction to tourists due to its famous historical sites, culture, attractive beaches and the Phong Nha - Ke Bang National Park, which is recognized as a World Natural Heritage Site by the United Nations Educational, Scientific and Cultural Organization (UNESCO). Dong Hoi City has a total land area of 155.5 square kilometers, administratively subdivided into 10 wards and 6 communes. As of 2003, the City registered a total population of nearly 99,197 people, of I which over 58,000 (or 60%) reside in the urban area (10 wards). In recent years, the economy of Dong Hoi has been developing at a high rate with its industry (manufacturing, construction and tourism) and service sectors increasingly contributing to overall gross domestic product (GDP). | 3.2 Summary of Current Environmental Sanitation Issues and Constraints Current issues and constraints from lack of environmental sanitation and related infrastructure 3 include: 3 * The urban drainage system, which basically consists of the combined sewer type, was built over the past two decades and has undergone a series of small renovations and upgrading. It is currently in a deteriorated state, and rapid urban growth, coupled with inadequate maintenance, I has rendered its drainage capability inadequate. The existing drainage system is located mainly in two (2) wards, Hai Dinh and Dong My. During the rainy season, the City's central areas are urban regularly flooded. | a The City's natural drainage system relies mainly on the Cau Rao River and Phong Thuy Channel, the downstream drainage flow of which has been drastically reduced by aquaculture activities, | vegetative overgrowth and settlers along riverbanks. These natural drainage flows are also constricted by several under-designed road crossings, which often are blocked by debris during I flood periods. . Not all of the generated domestic and industrial wastewater is pre-treated in septic tanks prior to 3 discharge to the environment. Some wastes are collected through the existing combined sewers. highly In populous areas, infiltration latrines are still used, creating risks to ground water quality. 3 . Wastewater from the largest hospital in Dong Hoi (the Vietnam - Cuba Hospital) merely passes through asimple small-scale aeration pond prior to discharge to the environment, while wastes from small businesses, restaurants and hotels are coursed through local septic tanks or settling tanks prior to discharge to the drainage system. * . Only 50% of solid waste generated in the urban area is reported collected. In some suburban 3 areas, collection is performed only in central markets. Collected solid wastes are disposed of openly in City dumpsite, some 8 km from the City center. the 3.3 Previous and On-going Related Projects and Studies | To help address these environmental sanitation issues and constraints, various project-related studies and programs have been conducted or are on-going, including: Final Environmental Assessment PART I 3.1 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City | . Adjustment of the development master plan of Dong Hoi, prepared by Urban Panning Institute in 2000, and approved by Quang Binh Provincial People's Committee (PPC) in 2001. | .

Urban area shall develop under Corridor shaped in combination with Multi Centric, base on topographical of the city and sustainable development. Bao Ninh is planned to be for commercial and tourist development area with specific master plan. U Population forecast: According to the plans, the City's urban population will be about 184,900 by 2020, in 62,200 which the urban population is 122,700 and this number in suburban area is Water supply svstem will continue to expand with a 2020 targeted domestic water supply of 130 liters / person / day and a population coverage of 90%. I | Wastewater drainage plan: By 2020, the inner city center will continue to use the combined sewer system with interceptors, while new development areas will use separated systems. Wastewater will be collected and treated in wastewater treatment plants (WWTPs). Solid waste plan: municipal solid waste will be segregated for recycling before disposal at the landfill and all hospital wastes will be burn in special incinerators. U 3.5 Master Plan Objectives for Environmental Protection * The importance of environmental protection and improved environmental sanitation are highlighted in I the current development master plans, which set the following targets . Prevent the risks of environmental pollution caused by socio-economic development activities. 1 . Protect the marine and coastal environment to sustain and enhance tourist develppment. .

Zone 5: Loc Ninh Area is mixed between hills and sea dunes with an average elevation of 10 m. There is no comprehensive database or surveys available of soil and geological conditions for Dong Hoi but most soils in the urban center are sandy based on local reports and observations. 4.3.2 Soil Conditions Dong Hoi's topography is that of a low coastal plain, the soil consists of deposits of sand and clay with a little gravel. According to the result of geotechnical survey, the structure of layer through 12 boreholes in 4 wards: Dong My, Dong Phu, Hai Dinh, Bac Ly, Nam Ly (studied areas of Phase 1) is as follows: Layer 1: The layer is dark yellow to grey alluvia layer with gravel, organic impurities. The consistency is medium dense, flexible to stiff. The layer is extends to depth of 0.0-2.2m. Layer 2: Mud clay with dead arca, very dark grey organic impurities. The consistency is porous - flexible - soft plastic. This layer is encountered at depths of 2.0-4.9m Layer 3: Composition is light, coarse sand with small gravel, white grey-to-light yellow. The consistency is dense, semi-stiff state. It is encountered at the depth of 4.0-7.Om Layer 4: Composition is clay with little small gravel, yellow grey. The consistency is dense, semi-stiff state. It is found at the depth of 7.0-9.4m Layer 5: Composition is sand with dust, motley, white grey, light pink. It is dense, stiff plastic. It is encountered at the depth of 4-9m 4.4 Flora, Fauna and Natural Habitats Quang Binh is located within the biological zone of north Truong Son with has a recognized high level of biodiversity and endemic species, particularly in the Phong Nha - Ke Bang National Park, which is a UNESCO World Heritage Site. This unique national park is located 30 - 50 km inland from Dong Hoi and extends until the Laos border area. The actual sub-project areas have very limited natural flora and fauna due to the level of urban development. Non-urban lands of the sub-project area are widely used for farming, dominated by paddy rice. No undisturbed native vegetation or natural habitats remains in the general area. The nearby coastal areas largely consist of sandy tp muddy beaches and offshore slopes. Representative photographs of the proposed sub-project areas are provided on the following pages.

As the coastal plain and urban area of Dong Hoi is only about 2 m in elevation above sea level, the lower reaches of these rivers within the city center are generally saline and influenced by the tides which typically range from 0.75 to 1.5 m but during storm surges this can reach heights of 2 to 3 m. River flow and discharge volumes very significantly between the wet and I3 dry seasons.

Key findings of the Pre-FS review are summarized in the following sections. 1 4.7. 1Drainage, Flooding and Wastewater Combined Sewers: The total length of combined sewers within the city as of December 2003 is about 31 km, most of which are made of reinforced concrete (RC) pipe with diameters ranging from 300 to 800 mm and the remaining combined sewers are constructed of brick box culvert with concrete cover slab. The quality of these pipes and culverts, which were built in 1995-1997, are in good condition. The remaining sections built prior to 1995 are reportedly in a degraded and partly collapsed condition. Flooding Situation: As a result of both the low laying elevation of some City areas and poor quality of drainage infrastructure and maintenance, floods are common in the following areas; - Downstream of the Cau Rao River in Duc Ninh commune. | - Along Tran Hung Dao street, west of the Cau Rao River. - Northern part of Viet Nam - Cuba Hospital property, in Bac Ly Ward. | - Paddy rice field areas of Loc Ninh commune. 3 - Urban areas of Dong My Ward and Hai Dinh Ward. The general location of the flood and inundation areas of the City is shown in Figure 1 - 4.3. According to the socio-economic survey, 26.3% of households said that their houses are frequently flooded in rainy season and 29% reported that they are sometimes flooded. Of these respondents, 31.9% Final Environmental Assessment PART I 4.10 _ ± Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City of households reported that the flood waters drained after half day and 33.1% reported that the flood waters drained after 3 days. Sewage System and Wastewater Treatment: The existing drainage system in Dong Hoi City is combined system; both wastewater and storm wastewater are collected in one system. This combined sewer system does not yet coverall of the city area, only in No.1 area (Dong Phu, Dong My, Hai Dinh wards) is the coverage complete. The total wastewater flow in Dong Hoi city is from 20,000 to 25,000 3 m / day, in which the domestic wastewater flow is from 7,000 to 8,000 m3 / day. According to the socio-economic survey, most surveyed households presently discharge their domestic wastewater into their garden (44.3 % of the total surveyed), while only 34% of households surveyed are connected to existing combined sewer system. The industrial wastewater in the area reportedly has a high organic content because the main industrial activities in Dong Hoi are fish processing, beer and soft drink manufacturing and only few manufacturers are present, such as the Pre-shaped Aluminium Frame factory. In general, no proper wastewater treatment facilities currently exist in the small industrial factories in Dong Hoi. Only some larger enterprises are equipped with a simple treatment facility, but the level of treatment and quality of discharged effluents does not meet national standards. Most of the wastewater from hotels and hospitals passes though primary treatment provided by simple facilities such as sep!ic or settling tanks before being discharged to the existing combined system. The Cuba Hospital is the largest general hospital in Quang Binh province with 200 beds. Average volume of wastewater generated by the hospital is about 300 to 500 m3 / day and it has a high concentration of biological oxygen demand (BOD) and chemical oxygen demand (COD). This is the only hospital equipped with wastewater treatment / aeration facilities which are not operated or maintained properly. l I' I l l l I Final Environmental Assessment PART I 4.11 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City \ ,/ Iyi Lk Ninh *7 .' .'p .

With it's current capacity, the Quang | ~~Binh Urban Works Company (UWC) can reportedly only collect about 50 - 55% of the 36,000 tons of solid wastes that is generated annually, which consists of domestic wastes (22,000 tons / year), | ~~industrial and construction wastes (14,000 tons / year) and hazardous (medical) wastes (25 tons / * ~~year). For this solid waste collection, the UWC currently operates some 6 trucks for waste collection and g ~~conveying, supported by 147 push carts and 1 bulldozer. | ~~~Final Environmental Assessment PART I 4.12 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Based on the Pre-FS, the summary composition of Dong Hoi's collected solid waste is provided in (Table I - 4.8). Important opportunities appear to be present to further reduce and minimize current | and projected volumes of solid waste, particularly of recyclable and organic materials. Hospital Wastes: The City's only incinerator is located in the Vietnam - Cuba Hospital but this I incinerator does not met proper sanitation criteria. The classification of domestic and hospital waste in this hospital is carried out regularly. The quantity of waste from other health services, such as private clinics is less, but it is not controlled or completely treated. Up to now, the UWC does not have a | special vehicle or containers for handling hospital hazardous waste collection and transportation.

Quang Binh Urban Works Company. Industrial Wastes: Some industrial wastes are not fully and properly collected and disposed of. However, the current volume of waste from industries in Dong Hoi is not considered a major component of the total volume of wastes. Private enterprises enter into individual contracts for industrial waste collection service with the Quang Binh UWC. Some of these industrial wastes are reportedly disposed of informally and illegally in the City's open areas creating an increasing problem for water quality and public health. Waste from commercial facilities: Unsorted wastes from hotels and restaurants are gathered in dustbins (waste storage containers), where it is collected by the UWC. The solid and vegetative waste | | on local beaches is also manually collected by the UWC workers in the same manner as waste 3 collection from the city's streets. | Waste from wet markets: wet waste is put in the corner of the market and a compactor truck collects 3 the unsorted waste daily for transport and disposal at the existing Loc Ninh dumpsite. If the truck does | not arrive as planned or is under repair, the uncollected piles of wet wastes quickly create sanitation and health problems in the open market area. | | 4.7.3 Status ofthe Existing Dong Hoi Dumpsite The existing dumpsite of Dong Hoi is located in Loc Ninh commune area, which is about 8 km from the city center. This dumpsite covers an area of 13 ha, and started operating in 1995. It is situated in a hilly area, which has been planted to pine forest. According to the local authorities, the Loc Ninh dumpsite * , has been listed by the government as being in violation of environmental regulations and is planned to Final Environmental Assessment PART I 4.13 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City be closed. The wastes deposited at this dumpsite are not levelled, compacted or well covered. Leachate is not properly collected and treated, and as a result, the leachate infiltrates directly to ground and pollutes water sources. The quality of this leachate as tested in 2002 (rainy season) is summarized in Table I - 4.9, indicating levels of COD and BOD above,national standards.

Under the Swiss-funded Dong Hoi Urban Development Project (DUDP), environmental assessmelnt (EA) studies of both the closure of the Loc Ninh dumpsite and opening of a new sanitary landfill site in Ly Trach were prepared in 2002. Implementation of these two related projects is apparently still in progress, with approval by the Quang Binh Provincial People's Committee (PCC) in March 2005. As part of the EA process, a due diligence review was conducted by the CCESP International Consultant, with a report separately submitted to the Bank in February 2006. I I II | ~~~~Final Environmental Assessment PART I 4.14 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City 5 ALTERNATIVES OF THE PROJECT The proposed Phase 1 investments are preparatory to and directly linked to the subsequent Phase 2 investments. A description of the "without project" situation and alternatives that were identified in the process of preparing the Phase 1 sub-project components is provided in the following sections. Additional comments to the Pre-FS and recommended alterative considerations were provided by the International Consultant in its' "Review of the Pre-Feasibility Study" report (Oct. 2005). 5.1 Without the Project Situation The preparation of the CCESP was initiated based on the understanding that the GoV lacked the financial resources to directly fund the proposed project investments. As a consequence, without project funding from the World Bank or other donors, it is assumed that these needed investments to improve environmental sanitation would not be able to be made by the GoV in the near future, if at all. As a result, public health risks and costs will increase and projected growth in economic development lead by tourism will be threatened. Delays in implementing the project as proposed may also lead to increased costs and social impacts at a later date, when current facility sites and needed right-of-way (ROW) areas may no longer be available. Under this "without project" situation, the environme.ntal sanitation conditions and related institutional capabilities will continue to decline, particularly within the densely population urban center. In contrast to recorded (1992 - 2002) annual population growth rates ranging from 1.0 %, official projections for 2003 - 2020 are 3.8 %. The generation and management requirements of liquid and solid wastes are expected to increase at even higher rates due to improving per capita economic conditions in the sub-project cities. 5.2 Drainage, Flood Control and Wastewater Collection Alternatives Various alternatives were assessed during the Phase 1 preparation activities, including: . Alternative sites of proposed WWTPs, which will be decided during Phase 2. . Alternative routings and configurations of the drainage and wastewater collection systems to support the proposed alternative WWTP sites. * Alternative capacity, pumping system and materials for the pipeline and channel systems. . Options for making the household connections to new sewer systems. 5.2. 1 Scheduling Options for Household Connections to the New Sewer System The pre-feasibility study recommends connecting 1,288 houses in Dong Hoi in Phase 1 before the wastewater treatment plants are completed in Phase 2. Doing so would result in varying volumes of untreated wastewater discharged to the receiving waters thereby increasing: - Pollution levels in the receiving water bodies; - Exposure of human and livestock to polluted water; and - The risk of waterborne diseases - diarrhea, cholera, typhoid, and dysentery. Final Environmental Assessment PART I 5.1 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City In assessing this option, the following advantages and disadvantages of household connections to the | new sewerage system were considered. The main reasons often given for making the connections early (i.e. before the WWTPs become I operationsl) are: a) It avoids excavating the street twice - once for the main line sewer and a second time when the house connections are made. b) It provides a large and or sufficient volume of wastewater to operate the wastewater treatment | plants immediately after they are completed. c) The wastewater can be tested so that proper design criteria for the wastewater treatment plants can be established. d) The customers that are connected will realize immediate benefits from the fees they will start paying because they will get their septic tanks cleaned. There are practical alternatives to the four (4) reasons advanced for the early connections a. Breaking the road twice: It is standard and normal practice in sewer construction to install the house connection laterals to the property or fence line - but within the property, at the same time the main line sewers are installed and by the same contractor. The end of the laterals in the property are then plugged and marked with a stake in the ground until it is time to connect to the houses. This avoids breaking and repairing the road twice. L | b. Sufficient wastewater to operate the plants: A significant volume of wastewater and enough to operate the plants initially can be obtained by making the following connections: Connect the hotel zone and the main commercial areas. The hotel zone is Tran Phu street, Hung Vuong street, Nguyen Thien Thuat street or in general the beach road and the streets west of the 3 beach road. c. Design criteria: Domestic wastewater is similar from one place to the next even from one I country to the next. The main factor influeneing the characteristics of domestic wastewater is J water usage pattern. There is nothing unusual about the water usage in Vietnam or the Coastal cities that would significantly affect the wastewater characteristics from the norm. | I Therefore the design criteria used elsewhere or those found in most textbooks can be used 3 practically or conservatively here. Also, the design criteria must be established a long time | before the house connections are made. d. Immediate benefits: Septic tanks are cleaned once every five to ten years. At best each household could expect to get their septic tank cleaned once if at all before the WWTP are * | completed. The risks and impact from prolong discharge of wastewater to the environment exceeds those of not cleaning the septic tanks for the 3-5 years to construct.the septic tanks. 3 Connecting households to sewerage system before WWTPs become operation-- is unusual although | there could be a good reason to do so when subsoil is predominantly clay or clayey, which would prevent the septic tanks from operating properly or would contribute to the wastewater writing to the Final Environmental Assessment PART I 5.2 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City surface. However, in Dong Hoi, the subsoil is sand or sandy in nature, and drainage is highly effective. With above advantage and disadvantage being considered, the following options were identified: Option 1: No households are connected to the new sewer system until the proposed WWTPs are operational. Existing households connected to the system would be allowed to continue | discharging their untreated effluents to the new combined sewer system. Option 2: Proposed household connections to the new sewer system will be rnade during construction of the sewer and before the proposed WWTPs are operational in year 2 or 3 of Phase 2. Option 3: The commencement of making the household connections to the new sewer system is delayed until six (6) months before the projected completion of the WWTPs to provide additional effluent flows within the system. Existing households connected to the system would be allowed | to continue discharging their untreated effluents to the new combined sewer system. I Regardless of the option followed, there will be no increase in excavations to make the household connections if all options share the same design for installing lateral connections if they are installed I to within the household property lines. So the issue of timing the connections with respect to excavations is not an advantage to any option. A summary of the identified advantages and disadvantages of each option is provided in Table I - 5.1. l Table I - 5.1: Summary of Advantages and Disadvantages of Household Connection Options | Option Advantage Disadvantage Option 1 No increase in risk to public health and May cause some delay in getting a significant flow tourism. to the WWTPs once these are completed. However, this can be resolved by connecting the hotel and commercial areas first. Option 2 Earlier environmental sanitation benefits to Increase in pollution loads and concentrations connected household. from discharge of untreated effluents. Public health and tourism risks Earlier collection of service fee revenues Prolonged risks if WWTP construction in Phase 2 is delayed Option 3 No significant increase in risk to public May present limited public health and tourism risks health and tourism. during 6 month period before WWTPs are | Potential risks are reduced if ~~~~~~~~~~~~~~~~~~~~operational. Provides a reasonable flow to WWTPs once connections are made during rainy season when these are completed. dilution and dispersion capacities are highest. 3 The most effective environmental mitigation measures for the additional pollution due to new household connections would be to postpone the household connections until the WWTPs are operational or advance the schedule for constructing WWTPs to provide treatment earlier in the Final Environmental Assessment PART I 5.3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City project period so that these project components are more closely linked (Option 1). However, if Option 2 above is selected, the new sewer system would be made during construction of the sewer and before the proposed WWTPs are operational in year 2 or 3 of Phase 2. Based on the assessment and hydraulic modelling calculations of this option indicate that the incremental etfect of the new connections would be relatively small. Combined with the existing conditions as described above, however, the dilution and dispersion capacity of the receiving water bodies are not adequate to assimilate current discharge level within national water quality standards. Therefore, disallowing household connections is incorporated in project design as a mitigation measure in lieu of this alternative. If it is agreed and locally approved to allow some household connections to the combined sewer system prior to completion of the WWTPs, this report considers the impacts, potential risks and presents some mitigation measures and guidelines. 5.3 Resettlement Alternatives Component 4 is designed to address the compensation and resettlement requirements of the GoV and the Bank of the 42 project affected households currently residing along the Cau Rao River and Phuong Thuy Channel. Key safeguard issues of the Bank include the issues of consultation, compensation on the basis of "market" or "replacement" values and rehabilitation of lost income and/or livelihoods. Based on the separately submitted, alternative preferences of some households may involve adequate cash compensation as opposed to physical resettlement. 5.4 Retaining the Septic Tanks: One objective of the project is to reduce the infiltr'ation of septage and wastewater to the ground water. The question of whether to retain the existing septic tank in service after the house connections are made, to retain the newer ones, or to completely abandone all is still unanswered. The prefeasibility and feasibility studies done by the National Consultant state that most of the septic tanks are either not designed properly, not functioning adequately or both. The report states that approximately 87 percent of the wastewater penetrates to the surrounding soil. If this statement is true or mostly true then a significant (the majority) volume of the wastewater will be lost through the septic tanks to the surrounding ground and very little will be transferred to the treatment plants if they are retained in service after the house connections are made. If the septic tanks are retained all should be 100% watertight and this should be confirmed by appropriate and recognized tests. The decision to retain should not be based on the age - i.e whether recently constructed or not, or whether likely to leak or not but rather that they are currently watertight and are more than likely to remain so for the life of the project. It will be difficult and costly maybe impossible to waterproof test all the septic tanks, and certainly it will be highly inconvenient. It would be a less costly to abandon all septic tanks. Final Environmental Assessment PART I 5.4 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City 6 ENVIRONMENTAL IMPACT ASSESSMENT Based on completed studies and local consultations, the sub-project is expected to have significant positive benefits for the environment, public health and the tourism-based economy due to reduced frequency and level of flooding in the City's urban center, improved collection and handling of liquid and solid wastes, and supportive improvements in sanitation service and capacity. From an assessment of proposed Phase 1 sub-project components, baseline conditions and consultations, supported by the experienced gained from similar types of World Bank-funded projects in Vietnam, the following four (4) key sources of potentially adverse environmental impacts were identified and are recommended for detailed management, mitigation and monitoring measures: (1) Impact of the construction work; (2) Temporary wastewater discharges from the outlets at the Nhat Le and Phong Thuy Channel (3) Transport and disposal of dredged sediment (4) Impacts of mine and unexploded ordinance removal (5) Potential cultural impacts to the 200 year old Binh Quan Citadel 6.1 Impacts of Construction Work The main activities of construction works during Phase 1 include: - Street excavations to install drainage and wastewater system and restoring these areas - Changing and installing 11 new inlets and 4 new discharge gates - Providing 25,000 m2 of new street pavement along upgraded sewer routes - Transport of materials to the construction sites - Temporary storage of dredged and construction material at the construction sites 6.1.1 Street Excavations The construction works for upgrading drainage and combined sewer systems will involve two catchments areas of Dong Hoi City, which are summarized in Table I - 6.1. Potential sources of environmental impact will include some 3,078 m of street excavations and an estimated 13,270 m3 .of excavated soil. These excavated materials are expected to consist largely of sand (the most common type of soil in the city's urban center) which will be directly re-used on-site for back-filling excavated pipeline trenches once installation has been completed. The estimated construction period along each street section is in the range of 1 - 2 weeks, during * which stockpiles of excavated materials along pipeline trench may cause dust (if excavations are conducted during the recommended dry season) and traffic problems is not properly managed. If excavations are made during the November- January rainy season, addition impacts are expected to U include increased flooding, soil erosion into drains and adjacent streets, and unsanitary stagnant | water filling open trenches.

The total amount of soil materials to be excavated for the pipelines is 13,270 m3 and it is expected that 50 % of these excavated sandy materials will be used on-site for - back-filling trenches. Disposal of the excess materials may involve estimated 2,700 vehicles trips (in and out) if 5 ton capacity trucks are used on constructed road with the length of 3,078 m. Based on a Final Environmental Assessment PART I 6.2 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City | 5-year project duration of Phase 1 (2007 - 201 1), the proposed excavation works may involve an average of 2-3 vehicle trips per day along 3,078 km of pipeline routes. 3 Based on the methods of the World Health Organization (WHO, 1993, an estimate of the generated 5 dust and other key air pollution parameters generated by transport-type vehicles is provided in Table I - 6.3 and I - 6.4. The existing baseline data (Annex 2) on some roads where the construction work will take place show that among the monitored parameters of air pollution (CO, S02, N02), the concentration of CO is still much lower than national standards while S02, is slightly higher than the national standard for urban areas. During project construction, elevated levels of SO2will be a key air 3 quality impact near the construction sites and along transport routes. However, this impact is identified to be short-term and limited to actual construction periods.

The predicted noise levels one (1) m from the point source of 3 noise is presented in Table I - 6.4 with the predicted attenuated noise levels with distance from noise | sources based on the following formula (Pham Ngoc Dang, 1997): Lp (X) = Lp (Xo) +20 logi 0 (Xo/X) (dB) Lp(X 0 ): noise from 01 with the source (dBA) X.= 1 m X: the location that needs to be calculat^d 3 Lp(X): the noise at the location that needs to be calculated Table I - 6.4 Predicted Noise Levels from Construction Vehicles and Equipment Type of Vehicle Noise Level - 1 m from Source Predicted Noise Predicted Noise 3 and Equipment Range Average Level Level 10 m Source from from 20 m Source Bulldozer 93 .73 67.0 I Leveler Excavator Concrete mixer 72.0 72.0 - 84.0 75.0 - 88.0 74.0 78.0 54 58 45.0 52.0 81.5 61 5, 55.5 National standard (TCVN 5949-1998): 50 - 75 dBA (between 6 AM - 6 PM) for residential areas 3 National standard for working environment issued by Ministry of Health: 85 dBA (8hour work day) During construction, the noise sources will be about 10 - 20 m away from residential areas. According to the existing baseline monitoring data (Annex 2), current noise levels along the city streets is around 65 - 75 dBA. Compared to baseline conditions, the noise generated by project construction vehicles Final Environmental Assessment PART I 6.3 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City and equipment will be higher than existing transportation noise. However, the predicted noise levels 10 - 20 m from the construction sources are reduced. The noise also could be higher due to some noise sources operate at the same time and together with the transport vehicles (from 82 to 94 dB). In some cases, the noise could be higher than the national standards at a distance of 10 m from the noise sources. It is predicted that some residences and businesses along narrow streets could be affected by the noise during the construction period which is expected to last not so long time for each street section and the noise management will be applied as show in Part 2 6.1.4 Impact to water environment Most of Phase 1 construction will be trenching and pipe installation. The construction will most likely establish an off site office and camps with shower and toilet for the workers as well as material storage and garage for vehicles. Workers will not be accommodated on the construction site. Domestic wastes generated by construction workers can be estimated based on the maximum number of workers working in the construction period, which is estimated at 200 workers. The estimated amount of generated wastewater is 40 m3/day if workers are allowed to bath at the working location. If we don't have any mitigation measures, the estimated BOD5 pollution could be in the range of 6 kg/day (30 gm / person / day). The domestic wastes generated during construction could affect local areas, soil and ground water if proper mitigation measures are not applied during construction. If construction site toilets with septic tanks are applied for treatment, the load of organic pollution from wastewater will be reduced by 50 %. The bad sanitary conditions at the construction sites caused by sediments and rubble, the worse effect on surface water quality of canals/channels (Nhat Le river, Phong Thuy channel) due to discharge of contaminated storm water, run-off water and domestic wastewater from workers sanitation. The contaminated stormwater is generated from the sites under excavation, piles of construction materials. This stormwater contains high suspended solids such as grits and clays. The volume of this stormwater is dependent on the area of sites and open store of construction materials and storm intensity. 6. 1.5 Impact from domestic solid waste Estimated solid wastes generation would be in the 100 kg/day based on a rate of 0.5 kg / person / day and assuming that the workers are allowedi to eat at the construction works. This is a small amount and will be collected and disposal by contractors. 6. 1.6 Leakage of Residual Grease and Oil During construction, grease and oil residuals may be generated from maintaining and preparing vehicle and machinery. According to technical documents, the average oil residual from construction machinery is around 7 liters per change of oil and the period of changing is every 3 - 6 months. If the estimated number of construction vehicles and related machinery is 30 units, the oil residuals that would be generated is around 30 -70 liters / month. The grease and oil wastes are recognized as a hazardous waste (code: A3020, Basel: Y8). If strict management measures for collection and disposal Final Environmental Assessment PART I 6.4 U Coastal Cities Environnmental Sanitation Project (CCESP) Dong Hoi City of residual oils are not applied, such residual wastes can be a potential source for soil and ground water pollution. 6.1.7 Impacts to Traffic Stockpiles of excavated soil and materials along the street excavation sites can cause temporary disruption of normal traffic flows and create public safety issues. Based on the above calculations, the amount of excavated soil can be a maximum of around of 3 - 4 m3/ m of road (in cases where main drains are being upgraded). If the height of soil stockpiles is about 1.5 m, the wide of road is 20 m, the temporary soil stockpile will occupy about 10 - 15 % of the roadway. For narrower streets, the percentage of roadway that may be temporarily blocked by soil stockpiles would increase proportionately. Most traffic using the project streets consists of motorcycles and bicycles, which can more easily adjust flow patterns. Proper traffic management and public safety measures are required to minimize these temporary traffic impacts and possible disruptions. 6.2 Discharge of Untreated Wastewater Effluents from New Household Connections Based on the CIP, 80 % of the households in the wards of Dong My and Hai Dinh are expected to be connected during Phase 1, or a total of some 1,288 households (estimated 5,032 people). This compares to some 2,128 people that are reported to be connected now. The discharged of untreated wastewater effluents form the proposed new Phase 1 household connections would be made through a series of outlets, which are located close to each to other along a short segment of Nhat Le River from the Cultural House in Dong My ward to the confluence of Nhat Le and Cau Rao River (including the confluence area). This large estuary - river mouth area represents the receiving water body for the outlet discharges during Phase 1. The four (4) combined sewer outlet areas that would be directly impacted in the Dong My Ward are Catchments Discharge Outlet Phan Boi Chau street Phong Thuy Channel Nguyen Du street: Nhat Le River (3 outlets - Le Qui Don, Han Mac Tu & Ba Huyen Thanh Quan) The five (5) combined sewer outlet areas that would be directly impacted in the Hai Dinh Ward are Catchments Drainage Outlet DONRE Hao Thanh Hung Vung Hao Thanh Nguyen Trai Street Nhat Le River Nguyen Viet Xuan Street Nhat Le Thach Han Street Nhat Le Due to the discharge locations of these outlets (Figure I - 6.1), the key concerns pf impact from the new household connections are the changes in the pollutant concentrations in the Phong Thuy Channel (2 outlets) and Nhat Le River (7 outlets). This water body receives fresh water with high flow rate from upstream and also has high level of tidal exchange with the sea. Due to this high water exchange / flow rate and the close proximity of the nine outlets, the estimated pollution load is calculated as a single value for this impact assessment (Table I - 6.5) which served to: Final Environmental Assessment PART I 6.5 I |~~~~~ia Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City | .

Therefore, to estimate the total load of domestic wastewater pollutants to be connected and discharged from the nine (9) outlets in Phase 1, the following "parameter of untreated values" from Standards for Infrastructure Construction (TCXD 51:84) were used: 3 Biological Oxygen Demand (BOD5): 30 gm/person/day Total Nitrogen (TN): 7 gm/person/day I | Phosphate (P205): 1.7 gm/person/day I Due to the lack of applicable standard for BOD, the load of COD will be applied from similar standards | issued by WHO and US Environmental Protection Administration: 50g/person/day. For total coliform, the average value is 250 mils /person/day. MODEL STUDIES: A mathematical model was done to estimate the impact of connecting the houses planned in Phase 1. * The following assumptions were made to simplify the analysis. 3 * The concentrations (BOD5, COD) and flow in the wastewater and receiving bodies are constant and uniform throughout. * There is complete mixing of the wastewater and the receiving body on contact at the discharge points. The likelihood of complete or near complete mixing of the wastewater and the receiving bodies occurring is dependent on: * Width of the receiving stream or channel Final Environmental Assessment PART I 6.8 3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City a Depth of the receiving stream or channel 8 Relative velocity of the stream and discharge | * Depth of the discharge. 3 Mixing to any degree - partial or complete will be promoted by turbulence (Reynolds No). In these coastal areas the receiving streams are generally considered as wide open channel i.e the width is greater than 5 to 10 times the depth, velocities are low in both the wastewater discharge and receiving streams. These conditions will inevitably result in laminar flow - and there will be very little 3 or no mixing across boundary layers. The most likely occurrence is a narrow band of highly polluted water on the discharge side of the stream or canal for a length much greater than that predicted by the simplified model. The risks would also be significantly greater than that predicted using the complete mixing assumption as well. The model makes little or no allowance for an extended lack of rainfall or for variation in BODs, both could markedly affect the results. 3 These assumptions will result in a simplified model, hence while the results and conclusions cannot be ignored but they must be reviewed accordingly and any decision based on the model analysis should consider the limitation and simplification of the model. Actual field results will always be higher than the model results because of the assumptions and simplifications. The different between the two results will be a function of the relative difference in volume. If the volume of the wastewater discharge and the receiving body are close then the resulting concentration will be close to that predicted by the model. If there is a significant difference in volume there will be a corresponding difference between the actual field and model results. In the latter case the model results will be very unreliable. U Impact Assessment of Pollutant Load Increase to Nhat Le River: The initial concentration of any I substance or microbial count of a river is determined by degree of initial dilution, which can be computed by the WHO method, through the following equation (Alexander P.E, 1993): Na = (QrNr + QiNi)/(Qr +Qi) (1) * Where: 3 Na, Pollution concentration of the river water just after discharge point Ni, Pollution concentration in the wastewater discharge stream Nr, Pollution concentration of river water just prior to the discharge point Qw, Input wastewater flow rate, m3/h Qr, River water flow rate (m3/h), in dry season 3 After the proposed new Phase 1 household connections are made, the predicted changes in pollution concentrations of the river water just after outlet discharge point can be computed based: | - Estimated increase in pollutant loads (Table 1-6.5) - Available hydrographic information on the Nhat Le River - Results of water quality testing conducted in December, 2005 and January, 2006 - Results of water quality monitoring conductdd by Quang Binh DONRE from 2002 - 2005, * Final Environmental Assessment PART I 6.9 l Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City The predicted changes of pollution concentration in Nhat Le River are summarized in Table I - 6.6. 3 Table I 6.6 - Predicted Changes of Pollution Concentration in the Nhat Le River after Phase 1 Household Connections BODs COD SS Coliform (mg/I) (mg/I) (mg/l) MPN/100m1l At present (concentration in the 21.1 56.1 14.2 80.4 x 103 | river just after discharge point) Phase 1 (concentration in the river 21.58 56.86 15.04 80.68 x 103 just after discharge point) 2.27% 1.4% 5.9% 0.35% Predicted Increase (%) TCVN 5942: 1995, Column B < 25 < 35 80 10 x10'3 In addition to dilution and dispersion factors, the predicted increase in BOD5 and coliform | concentrations will be reduced through natural decay as measured by time or by the distance from the discharge outlet. For calculating these decay rates, the following formula and factors were applied: | Nt = Na e-kt (2) The relation between time t and the distance form outlet can be given by the equation: Where: L = (Qr+ Qi)/(h*l)*t *24 (3) (m) j * ~~Where: 3 NL: Pollution of river water after the elapse of L (m) from outlet. | K, decay rate constant is dependent on the stream water temperature, can be computed by following equation: K = K2oeT-20 (4) K- die -off rate The reported value for coliform die off is in the range of 1.0 day-1 for large streams to 1.8 day-1 for medium size streams, while the constant e is 1.075. If the average temperature in Nhat Le River is 25oC, then K for Nhat Le River is K20, Microbial die -off constant at 2OoC day-1 = 1.8, so K coliform at 26.5 oC 9.675 K20, BODs of = 0.08 day-1 K BOD5at26.5oC = 0.15 * | T, time L, distance downstream from outlet. | h. the high level of water = 1.8 m I, the width of Nhat Le river = 570 m Based on equation (2) and (3) above, the predicted reduction rates for coliform concentrations is presented in Figures I - 6.2 Final Environmental Assessment PART I 6.10 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Figure I - 6.2 Predicted Change in Coliform Concentrations with Downstream Distance from Outlet 90000 80000 70000 60000 Co 50000 > < 5 r 40000 30000 20000 1 | 10000 20 S e 0 i 0 10 20 30 40 50 60 70 80 90 Distance (m) Based on these calculations, when additional household connections are made in Phase 1, it is predicted that the pollution near the outlets will be increased but not remarkably comparing to the existing pollution situation. The concentration of coliform, and COD near by the outlets in Nhat le River would be higher than allowed by national standards but these pollution concentrations are reduced with distance from the outlets. Based on the above calculations, the predicted concentrations for coliform will meet national standard within 90 m downstream of the outlets. These predictions are I based on the assumption that all discharges will be made from just one outlet (due to the close proximity of the 9 outlets). If we could calculate the discharge impact of each outlet, it is predicted that the pollution concentrations would be more dispersed and impacted areas (decay distances to met national standards) may be closer to each outlet. The sample taken from the site near by the outlet in Phong Thuy Chanel (see Station Ti in Annex 2.2) also showed that the COD and coliform parameters are much higher than allowed by national standards. The poor water quality of this constructed channel is visible to the naked eye with the I black-gray color of wastewater near the outlets (see picture in Chapter 4). A special concern is raised for any additional discharges to this Channel along which Outlets 1 and 6 are located due to its existing poor water quality and a significantly reduced dilution and dispersion capacity as compared to the Nhat Le River. | Recommendation: As described in Section 5.2.1, the existing COD and coliform concentration in Nhat Le river are exceeded the national standard. Although the analysis demonstrates that these' concentrations in Nhat Le River will meet national standard within 90 m downstream of the outlets, the main concerns are the potential risks for public health, especially for the local communities along the river and those whose livelihood depends on the river. The most effective impact mitigation meas ire is to postpone the household connections until the WWTPs are operational or advance the schedule for constructing H | Final Environmental Assessment PART I 6.11 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City | WWTPs to provide treatment earlier in the project period so that these project components are more closely linked. However, if it is agreed and locally approved to allow some household connections to the combined sewer system prior to completion of the WWTPs, This report considers the impacts, potential risks and presents some mitigation measures and guidelines. 1 6.3 4. Excavation, Transport and Disposal of Dredged Sediments and Septage Based on the sub-project CIP, the proposed areas and volumes of dredging activities are: 3 - Cau Rao River: 138800 m Phong Thuy Channel: 23,900 m3 - - Nam Ly Lake: 20,598 m3 I - Sediment 183,298 m3 3 - Sewer: 520 m - Septic tank material: 78 m3 Key impact concerns of these proposed activities include potential impacts to existing aquatic ecology, air quality and safety; transport, and disposal. I | 6.3.1 Impact of Sludge Excavation The impact to aquatic ecology: The proposed dredging areas involve key components of the City's | drainage, wastewater discharge areas and water storage system. The Cau Rao River is one of four main rivers of Dong Hoi City, which are connected by the Phong Thuy Channel. Most of tile proposed dredging will be conducted along both sides of the Cau Rao River (13,880 m3), involving the North Bank (total length of dredging activities: 1,780 m) and the South Bank (total length of dredging activities: 1,770 m). To restore drainage capacity and river profile, a volume of about 55 m3 will is dredged along each meter along these two river bank sections, involving dredging to a sediment depth of about 1 m. Based on site surveys, local consultations and information provided by the L L DONRE, the existing aquatic ecology and water quality conditions of the targeted dredging areas are poor. The proposed dredging activities are expected to help restore water flows, exchange capacities and quality in the lower sections of the Cau Rao River and Phong Thuy Channel as well as in the adjacent Nam Ly Lake. Following the short-term impacts of the dredging activities to benthic ecology and water visibility, it is expected that the drainage and water flow improvements will also help restore the ecological values of these waterways. ll A key impact concern from turbidity impacts during dredging are the extensive (and illegal) shrimp pens located near the mouth of the Cau Rao River. To minimize such turbidity impacts, it is * | recommended that dredging schedules be locally planned and announced well in advance of actual activities so that shrimp farmers can time their activities and harvests accordingly. l II Final Environmental Assessment PART I 6.12 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City 6.3.2 Impact Disposal of Dredged Sediment and Transport Sediment samples were collected within the proposed dredging areas in February 2006 and tested for key quality parameters to assess disposal impacts and any special handling requirements. The summary results of this sediment testing are provided in Table I - 6.7 and supporting laboratory results are proVided in Annex 2. There is no Vietnamese sediment quality standard, so similar to recent EAs prepared for World Bank funded projects, quality standards and sediment classifications used in Dutch Soil Clean-up Guidelines (1995; 1999) were applied as summarized in the Table below.

Following general practices and land use in the area, it is expected that these dredged sediments will be used for agricultural and/or landscaping use near to the dredging sites. Due to the high organic content of these sediments, this use of such material for constructing river or lake embankments or for fill | materials at the resettlement site are not recommended. It is recommended that temporary "de-watering" and partial drying will be conducted along the river banks where dredging is conducted.. This drying process will greatly reduce the volume and weight (about 50 %) of the dredged materials and reduce possible impacts form their transport. It is estimated that a drying area 20 m by 1,770 m along Cau Rao River and 8 m by 1500 m long along Phong Thuy Channel may be needed for recommended sludge drying activities which would need to Final Environmental Assessment PART I 6.13 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City be conducted during the dry season to be effective. Based on recent site surveys, open areas for such sludge drying are available near the dredging sites. In the case sludge is stockpiled and kept on-site for de-watering purposes, retaining structures and dikes will need to be provided to prevent sludge leakage to surrounding areas and surface waters. The projected sediment volume is very large of some 183,298 m3 , however as our recommendation 3 that if the sediment is de-watering, the volume of sediment much reduce (around 100,000 m ). This volume may require an estimated 20,000 vehicle trips if typical 5 m3 (in case the sediment directly transport out of dredged capacity trucks are used to bring dredged material to the selected disposal site(s). The impact of these dredging and sediment transport activities will be distributed over a several year construction period and will primarily involve areas near to the lake areas which are less populated. Because the dredged sediment will be very wet, leakage of muddy materials and liquids will be an important impact concern during transport if the proper measures and vehicles are not used 6.1.3 Impact of Sludge and Septic Tank Management, Transport and Disposal At present, the septic material is managed by Public Works Company. The septic material is removed and transported by special vacuum trucks. Based on available reports, the volume of septic materials that is removed and transported is some 78 m3 /year. With small volume of septic material and special vehicle, the impact to transport is not significant. Following anaerobic digestion in a properly functioning septic tank, the septic material is locally considered as a good and free fertilizer source, rich in nitrogen and phosphate. Following traditional agricultural practices, these septic materials are directly applied in rice field and gardens, which are very common around Dong Hoi. The volume of dredge sludge in sewer is small volume of 520 m3 will need to be placed directly into transport tankers and brought to the disposal sites, it is recommended in the landfill, to minimize storage time and impacts at the site. 6.4 Impact of Mine and Unexploded Ordinance Removal The potential presence of unexploded mines and ordinance is a recognized issue in the Dong Hoi area. Local concerns for potential impacts to residents and work crews during construction included areas to be excavated under the city streets and areas to be dredged. Within the CIP cost estimates, budgets are provided for de-mining operations of proposed project sites. To minimize potential impacts, these activities will need to be well coordinated with concerned agencies and capable sub- contractors well in advance of proposed work schedules. 6.5 Potential Cultural Impacts to the Quang Binh Citedal Based on site surveys and local consultations, the proposed sub-project sites do not include any known physical cultural resources, with the noted exception of the 200 year old Quang Binh Citadel. Proposed drainage works in the Citadel area (Figure I - 6.2) are located more then 150 meters away from this historic structure which is currently being renovated by the Department of Culture and Information, including similar types of drainage improvements to help protect this building from floods.

If the septic tanks are retained all should be 100% watertight and this should be confirmed by appropriate and recognized tests. The decision to retain should not be based on the age - i.e whether I recently constructed or not, or whether likely to leak or not but rather that they are currently watertight and are more than likely to remain so for the life of the project. We believe it will be difficult and costly maybe impossible to waterproof test all the septic tanks certainly it will be highly inconvenient. It would | be a less costly to abandon all septic tanks. Retaining the septic tanks (or some of) or the project will incur four (4) additional costs: * Cost of cleaning and maintaining the tanks periodically * Transporting the septage to the treatment plants or landfill sites I * Treatment * Cost of storage in the landfill 3 All these costs which can be substantial but would be avoided if the septic tanks are abandoned. The cost of treating septage is especially prohibitive because the septage is several times stronger than 3 domestic wastewater. The wastewater treatment plants would also require special design to handle anything other than low volume of septage. It is normal practice elsewhere to connect the households directly to the mainline sewer for this type of system and to design the treatment process accordingly. There is no good reason or significant advantage to retain the septic tanks after the house connections are made. The treatment plants will be designed for domestic wastewater consistent with * direct connection to the system. Accordingly, we recommend that all the septic tanks in the system be abandoned at the same time | the house connections are made. This will also avoid excavating twice in the premriises. U 6.7 Impacts Identified during Public Consultations 6.6. 1 Public Consultation Meetings Following completion of the Pre-FS, initial consultations were held in February 2005 with local government agencies, lead by the Provincial People's Committee (PCC) and the 6ONRE, and other concerned stakeholders. These initial consultations focused on pipeline route alternatives, transfer X stations, public toilets and potential impacts. The consultation Minutes are provided in Annex 3 6.6.2 First Stage of Public Consultations Final Environmental Assessment PART I 6.16 11 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City As required by the Bank safeguard policies, a first stage of public consultations with PAPs and local 3 community representatives was conducted in September - October 2005 and involved household surveys and interviews of some 300 households in the directly affected communities, a sample size representing 5 % of the total population of three wards that are a focus of Phase 1 subproject activities. No objections to the project or environmental and social concerns other than those addressed in the EA were raised during the consultative process. A summary of these conducted I household surveys and consultations are provided in Annex 3. Prior to conducting these household surveys, focus group discussions and consultative meetings were organized and conducted on September 29 - October 10, 2005 with a total of 81 local community leaders and members. | 6.6.3 Second Stage Public Consultations U A second and final stage of consultations focusing on the draft EA report was organized and conducted on December 27, 2005. This half day consultation, involving 20 participants was held in 3 Dong Hoi City and the complete Minutes are provided in Annex 3. This second stage of consultations was supplemented by a written questionnaire survey conducted in February 2006 for stakeholders residing near proposed discharge outlets. In addition to general support for the proposed project, the | key impact concerns that were raised by the 20 surveyed households included: * The existing problems in respondent'.s area: U - Pollution by traffic (dust, noise, and air emissions) - Pollution from open channel - Flooding during heavy rain and tides 3 - Uncollected garbage - Lack of household toilets | * Expected environmental impacts during construction of Phase 1 investments: - increased traffic - Increased noise | | - Increased dust 3 - Increased actidents | - Interrupted water supply - Stockpiles of materials and dredged sediment - Increased garbage from construction - Increase odors · Expected environmental impacts of increased outlet discharges during Phase 1: - Increase pollutants in the river Impacts to ground water I - - Increased odor - Increased public health risks | - Increased mosquitoes and flies * Recommended mitigation measures for increased outlet discharges: - Use chlorine for disinfection - Install coarse screen * - Monitor water quality Final Environmenlal Assessment PART I 6.17 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City - Regularly check and dredge areas near outlets 3 - Conduct public awareness program All the responses are ranked by the no, light, moderate affects. The most common concerns about the existing environment are the polluted condition by open channels (80% correspondents) and the pollution caused by traffic (45%) and uncollected garbage (40%). During the construction stage, the most comnmon impact concerns were increased odor (80%), noise and dust (65 and 60% respectively). The most common concern about the expected impacts of increased outlet discharges *rwith the proposed new Phase I household connections are: Increased odors near discharge areas (100 %), 3 * . Mosquitoes and flies (100%) * Increased public health risks (95%), | Increased level of pollutants in the river (85%). During construction, most of respondents agreed with the impact mitigation measures proposed in the draft final EA. For the proposed Phase 1 increase in outlet discharges, most people considered that the proposed impact mitigation measures have moderate effects. | Public Disclosure: Complimentary to public consultations, public disclosure of the EA report is 3 required in accordance with World Bank Procedure (BP) 17.50. The draft EA was disclosed in Washington DC and the Vietnam. Development Information Center (VIDC) in Hanoi by January 19, 2006. The Vietnamese translations were disclosed by January 13, 2006. All documents were I disclosed locally by the Provincial People's Committee (PCC), the provincial Department of Natural Resources and Environment (DONRE), the Project Preparation Units (PPUs), offices of the Wards in which people will be affected by the project, and were accessible to local NGOs and PAPs.

The plan also includes the actions needed to implement these measures. In accordance with the Bank's OP 4.01, the EMP serves to: I Identify the set responses to potentially adverse impacts; (a) (b) Determine requirements for ensuring that those responses are made effectively and in a timely manner; and I Describe the means for meeting those requirements. (c) 7.2 Mitigation Measures during Detailed Design | 7.2. 1 Generic Design Instructions Environmental matters have to be integrated in all the design work and planning of the project. The | detailed designs need to minimize adverse impacts on environment by maximizing the use of existing facilities and selecting the location of new facilities in areas where the disturbance to the environmeint, people and existing structures is minimized. Where possible, existing right-of-way (ROW) areas should be used rather than create new ones. The key mitigation measures will be provided in the Project Implementation Plan, Engineering Design Reports, Bidding Docurments and Contract | Documents. U According to the Vietnamese Construction Regulation Standard Article 3.3 (Protection of the Natural | Resources and Environment), construction projects should: . Not cause adverse effect to environment, and technical regulations on scenery and environment I | protection should be observed, * Protect natural preservation areas, and historical, cultural and architectural places, | . Ensure rational and sustainable use of natural resources, and . Respect traditional customs, practices, and religions of local people. In the Vietnamese Construction Regulation Standards, there are general instructions especially for I the design of sewerage and drainage systems to ensure that the constructed systems are: . Able to discharge all types of urban waste water Final Environmental Assessment PART II 7.1 I Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Suitable solution for treating wastewatei- so thatL the urban area is not flooded and environment and water sources are not polluted. In the nalonal standards for Branch Sewerage and Drainage System Works, there are mnore detailed design instructions which will be supplemented as needed under the project by international design standards to enhance the overall designs and environmental mitigation measures they provide. As part of the detailed design, the construction works will also be scheduled in an appropriate mannier to minimize the movement of construction equipment and disturbances to the site and nearby communities. 7.2.2 Drainageand Sewerage In the design of drainage and sewerage, attention has to be paid to preventing the possibility of contaminating the domestic water supply. Special attention has to be paid to the possible crossing of water pipes and sewers. For this purpose, it will not be allowed to have water pipes going through the same drainage manholes or box culverts. If possible, the drainage and sewer systems should be designed to be located as far as possible from water pipelines. Discharging points of the drainage system have to be selected so that the adverse impact is minimized and the back flow of drainage water to pipes is prevented or minimized. Drainage design principles have to be selected in co- operation with the other projects being implemented in the same area to ensure consistericy betweeni projects and to optimize the effectiveness of the constructed drainage system with minirnal site and community disturbance. Upgrading and dredging of channels has to be designed to minimize the need of resettlemnent and to assure proper construction and maintenance access is provided. Transport and disposal of excavated material has to be properly designed and appropriate disposal areas identified and reserved. To minimize transport and off-site impacts, maximum on-site or near site use of excavated and dredged materials will be encouraged. Deposited solid wastes and any contaminated sludge materials whicth are blocking existing drainage pipelines and channels will be transported to the landfill for disposal, but most excavated organic materials can be used locally for agricultural and 11-ndscaping purposes. Handling and disposal of sediment and solid waste to specified places with suitable means of transport has to be coordinated with relevant authorities. 7.3 Mitigation Measures during Construction All construction work funded by the sub-project will need to be implemented in accordance with the appropriate standards, specifications and Bidding / Contract Documents. The preparation of these Bidding / Contract Documents as well as the TOR for the construction management consultants (CMC) will be subject to Bank reviews and issuance of a No Objection Letter (NOL). A summary of t these nmeasures which have proven effective i'n managing potential environrmental impacts during construction is provided in Table II - 7.1.

Site Regulations and Safety: The contractor shall prepare and submit proposed site regulations for the PMU's approval prior to the start of construction. Such site regulations shall include, but not be | limited to, rules in respect of security, safety of the facilities and public, gate control, sanitation, medical care, and fire prevention. Signs.to show the name of the project, the name of employer and U the name of contractor have to located in visible places in the construction site. Noise, Odor, Litter and Dust: The maximum level of noise that will be pernitted in public and 5 residential areas is defined in Vietnamese standard TCVN 5949-1998,. The strongest limitations are from 10 p.m. to 6 a.m. in the vicinity of hospitals, sanatoriums, libraries and schools where maximuin 3 noise level allowed is 40 dB. | The contractor is responsible to collect all the solid waste from work sites and transport it to the landfill. In the construction sites, dust, litter and public inconvenience have to be minimized by good I construction management and site supervision. To minimize dust emissions caused by construction * works regular, sprinkling or preferably wetting of the streets is recommended. Streets that are 3 prepared for asphalt restoration will be sprayed with a prime coat of MC-30 asphalt to mitigate and | surpress dust creation. If there is a need for the incineration of any solid wastes at the construction sites, an appropriate control measure is required, and the local authorities will be informed of these | activities prior to their implementation. Waste and disposal of excavated materi?)s has to be disposed at the sites, which are agreed with URENCO. Appropriate equipment should be used to prevent overloading of trucks and to collect accidental spills (sludge, oils from equiprnent, etc.) during the construction works. Safety, Security and Protection of the Environment: The contractor shall, throughout the execution * and completion of the works and remedying of any defects therein: * . All local health requirements and safety methods and instructions as described in the Contract Documents will be followed. For any proposed work camp where workers will stay 3 overnight, the contractor will be responsible for providing appropriate guidance and information material on community relations and HIV / AlDs prevention in coordination with local health officials. Full regard will be given by the contractor for the safety of all persons entitled to be upon the site and keep the site and the works in an orderly and safe condition. Final Environmental Assessment PART II 7.5 U! 3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City Provide and maintain at his own cost all lights, guards, fencing, warning signs and flagmen, when and where necessary for the protection of the works or for the safety and convenience of the public or others, and * Take all reasonable steps to protect the environment on and off the work site and to avoid damage or nuisance to persons or to property of the public or others resulting from pollution, noise or other causes arising as a consequence of his methods of operation. During the construction works, the contractor shall keep the site reasonably free from all unnecessary obstructions and shall store or dispose of any contractor's equipment and surplus materials ana remove from the site any wreckage, rubbish or temporary works no longer required. The contractor shall have designated staff who are trained and responsible for site safety and accident prevention. The contractor shall be responsible for reporting the details of any accident as soon as possible after its occurrence. The contractor is further responsible to provide appropriate equipment, tools and protective clothing to the construction workers. The contractor has to ensure that appropriate working methods are applied. For example, anti-vibration mountings and noise insulation on equiptnent has to be used when possible. The contractor has to provide and train workers on how to use appropriate ear protectors when noise level in the working place exceeds 85 dB. Traffic and Transportation Arrangements: All operations necessary for the execution and completion of the works and the remedying of any defects therein shall be carried on so as not to interfere unnecessarily or improperly with the convenience of the public and/or access and use of public or private roads and footpaths. The contractor shall use every reasonable means to avoid traffic disruptions and to prevent any damage to roads or bridges used as transport routes. Work at Night and on Holidays: Unless otherwise provided in the contract, no work shall be carried out during the night and on public holidays without prior written consent of tile PMU, except where work is necessary or required to ensure safety of the facilities or for the protection of life, or to prevent loss or damage to property, when the contractor shall immediately advise the PMU. Public Relations: The PMU shall announce the construction works and any new traffic arrangernents during these works to the public through appropriate media (local newspapers, TV and radio) and through the ward representatives. As needed, loudspeakers can also be used during the construction work to provide the latest information to concerned areas. It is extremely important to inform the ward chairman and local residents in advance about any possible public disturbance or nuisance that may be caused by the construction works to mitigate such possible impacts. 7.3.2 Standards for Making Households Connections Based on the Final Report (January 2006) for the World Bank's Household Connections Mission, there is a recognized need to prepare project-specific standards for making household connections to the improved wastewater collection systems. Such standards are needed to ensure that when the household connections are allowed to be made, these connections will be made in a uniform manner that minimizes impact during installation and allows for proper maintenance. As described in this Final Report, these connection standards will be prepared during the project's detailed design stage by the National Consultant, working in close cooperation with the URENCO and WSSC (who will be in charge of maintaining the sewerage network) and with the Ministry of Construction and the Bank who Final Environmental Assessment PART 11 7.6 lIl Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City will need to approve the standards. It is expected that these connection standards shall provide a clear definition of: * Agreed procedures and typical arrangement for making connections (with schematic drawings to be followed); . Identification of possible connection points to the tertiary network (manholes, chamber or straight to pipe); * Materials to be used, minimum and recommended pipe diameters and slopes; * Number, placement and detailed design of any required special appurtenances (grit cambers, connection chambers, etc.). . If the septic tanks are retained, the condition for retention should be stated, * If the septic tanks should be abandoned, the method of abandoning should be stated. It is expected that these connection standards shall further define the arrangements for the existing septic tanks which will become redundant facilities once the WWTP(s) are completed in Phase 2. 7:3.3 Specific Mitigation Measures during Dredging Activities The current estimate of the total volume of dredged material is 160,000 m3 . Based on the results of sediment testing conducted as part of the EA in February 2006, this dredged sediment is expected to consist primarily of organic materials which could be re-used locally without further treatment for agricultural and landscaping purposes. The amount of dredged material will be clarified during the detailed design and more detailed instructions will be included in the Contract Documents. Specially, the contractors will be required to use special vehicles (tankers) for sludge transport to any off-site disposal area(s) to minimize leakage of sludge materials. Any dredge sediments which are later found to be contaminated or not suitable for agricultural or landscaping use will be disposed of in the landiili site. Prior to disposal, the sediment can be dried out for use as covering layer at the dump site. Such disposal will need to be agreed with PMU, DONRE and the UWC. To avoid public disturbance during dredging works, the local ward chairman, residents and other concerned stakeholders will be informed in advance about the dredging schedule and work plan, including information on any proposed sludge dewatering and/or on-site storage activities. 73.4 Specific Mitigation Measures for Mine and Unexploded Ordinance (UXO) Clearance Because of the potential mine/UXO risk in the Dong Hoi area, arrangements will be made with Quang Binh offices of the People's Army of Vietnam (PAV) to provide adequate mine/UXO clearance services as needed during excavation and dredging works, In addition, arrangements will be made with these parties to provide adequate mine/UXO risk education (MRE) and training to the PMU, all contractors, consultants and any other field staff, as follows: . Basic knowledge about the mine/UXO threat in the Dong Hoi sub-project areas, . Knowledge on the official and improvised mine/UXO signs used in Vietnam, . Knowledge about commonly used landmines and UXO that can be found in Vietnam, . Understanding about the procedure to follow should mines/UXO be discovered. All field staff must have received mine/UXO awareness training prior to commencement of work in the field, and be provided with refresher training at least once per year during the construction period. Coordination with be established with related on-going projects in the area prior to start of any Final Environmental Assessment PART li 7.7 3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City construction and dredging works. In Quang Binh province, in addition to GoV activities, these related projects are expected to include the US-funded National UXO/Landmine Impact Survey being conducted in partnership with the Technology Center of Bomb and Mine Disposal (BOMICEN) of the Vietnamese Ministry of Defense and MRE programs lead by UNICEF. Steps to be Taken in when Mines/UXO Discovered during Construction: In the event that contractol- work teams discover mines/UXO, the following steps shall be taken: I a) The contractor shall immediately cease work activities within a 50 m radius of the site of the discovered mines/UXO. 3 b) The contractor shall immediately notify iie PMU, who in turn shall immediately arrange with the PAV or contracted party for the removal or other suitable treatment of the mines/UXO. 3 c) When the mines/UXO have been suitably dealt with, PAV or contracted party shall notify the PMU in writing and accompanied by an Incident Report, or a Certificate of Clearance. The Certificate shall clearly define the area concerned and be supported by the log sheets giving details of the types of survey carried out and the types and methods of disposal of, the mines and UXO encountered. d) When in receipt of written notice from the PAV or contracted party and a copy of the Incident Report (Certificate of Clearance), the PMU inform the contractor in writing that works can continue in the affected area. Safety and Medical Mitigation Measures: The contractor is solely responsible for safety of its staff and equipment, and for safety of any third person and third person's goods and properties, present on the Extended Site during execution of the Works. For this purpose, the contractor shall provide adequate medical support and casually evacuation capacity consistent with International Mine Action Standards (IMAS) and own procedures. At a minimum, the Contractor shall ensure that: a) One trained medical orderly equipped with adequate first aid kit, and a vehicle fitted for carrying a stretcher (for use as a dedicated ambulance), are available to the Team when Mine/UXO Clearance is in progress; the medical orderly and the ambulance driver shall be in permanient contact with the Tearn leader; anid b) The medical orderly, the ambulance driver and the Team leader know the adequate procedures for first emergency care and transport of injured personnel to hospital, as well as the location of the near-est medical facility (and the corresponding routes). c) Provide reliable communication means between contractor field supervisors, the Engineer, PAV or | contracted party and with local medical services and facilities. d) Protect the drivers of machinery used for excavation and clearing from an accidental detonation. Protection should be obtained either by fitting the machinery with protective shields and/or attire the drivers with protective equipment. The minimum requirements for protective equipment are the requirements specified in IMAS. The contractor must describe the equipment and procedures to be used to protect drivers and workers in details. Furthermore a safety distance from machinery to persons not involved with the road works should be established. 7.4 Mitigation Measures during Operation 7.4.1 Drainageand Sewerage During operation of the drainage and sewerage systems, the following impact mitigation measures will | L be applied in coordination with local community stakeholders as described in the following chapter: Final Environmental Assessment PART 11 7.8 I~~~~~~~~~~~~~~~~~~~~~~~~~ 3 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City . Regular visual inspections have to be made of the condition of roads where pipeline excavations are made; new drainage systems, solid waste collection equipment and services, public toilets and solid waste transfer stations. Based on these visual inspections and local reports, any possible breakages, problems or service disruptions will be reported immediately to the PMU and URENCO for repair. * Operational and safety standards have to be followed * Maintenance of drainage system has to be arranged; transportation of dredged material has to be done in proper means of transportation and loads have to be covered during transport to the landfill or other disposal sites; the dredged material has to be transported to the landfill or other suitable place agreed in advance with DONRE and URENCO * Trees should be planted on embankments of the open drainage canal to strengthen these structures, reduce air pollution and to enhance the local landscape. 7.4.2 Untreated discharge from Household Connections. The most effective mitigation measure would be to postpone the schedule for supporting household connections until the WWTPs are operational or advance the schedule for constructing WW EP to provide treatment earlier in the project period so that these project components are more closely I linked. However, if it is agreed and locally approved to allow some household connections to the combined sewer system prior to completion of the WWTPs, mitigation measures for "end of the pipe" treatments | to reduce impacts and potential health risks are recommended. Connections in Phase 1 can be done 3 at outfalls disposing to Nhat Le river, because of large river water volume and its strong water | exchange. The Phong Thuy channel is already polluted at present, and it is used for irrigation during dry season. Discharging more wastewater to this channel would increase pollution expose the farmers I and their families to polluted water and other public health risks. It is recommended that in Phase 1, the houses that already connected to the sewer will be allowed connecting, but there are no new house connection should be done in phase 1 for outlet 1 and 6. In general, all houses that are | currently connected to the system will remain connected. 3 | Although the characteristics and flow at the various outlets are dissimilar we are proposing the same mitigation at each outlet for the following reasons: - The current characteristics were determined from limited sampling over a short period that did not include all the seasons. It is possible, indeed likely that these characteristics will change. Therefore we believe it is prudent to be conservative and design for the worst case. An indication | of the worst case can be established by reviewing the result of all the outlets. - If there are changes in the characteristics for even a short period a conservative design will | mitigate the impact. - The equipment for the different outlets will be standardized, parts will be interchangeable and unit cost will be reduced. Final Environmental Assessment PART II 7.9 Coastal Cities Environmental Sanitation Project (CCESP) Dong Hoi City - To propose individual mitigation for what is essentially the same impact or could be the same would be tantamount to micro-managing without considering the possibility or likelihood of | changes. In both cases proposed above for outlets discharge to Nhat Le River and Phong Thuy channel. * Mitigation measures in projected areas should include: * At outfall, manholes should be designed and constructed (overflow manhole designed in I Phase 1 can be used) to input disinfections (chlorine) in order to kill pathogen bacteria. Liquid chlorine will be injected in a manhole automatically. The manhole will be designed to pernlit 3 adequate mixing of the chlorine and wastewater. The liquid chlorine will be stored in plastic drums in aspecial building constructed for the purpose * Placement of coarse screens on the outlets to help remove visible / floating solids. 1 . Increased water quality monitoring of discharge areas, public awareness programs, and signage to alert the public and tourists of aniy potential health risks in the effluent dispersion | areas; . Periodicly dredge of sludge in sewers and outlets Summarized existing environmental conditions, baseline conditions, changes in baseline conditions | resulting from the additional house connections and recommended mitigation are represented in table 11-7.2 l 7.4.3 Septic Tanks.- | The majority of the septic tanks are either poorly designed, leaking, in need of major repairs or not functioning properly. If any is retained in service the long term integrity should be convincinigly established by appropriate tests. This will be difficult, expensive and inconvenient. (Septic tanks are 3 usually tested before placing in service). They will serve no useful purpose after the house connections are installed. They should be abandoned completely at the same time the house connections are made. The procedure to be followed to abondone these tanks are: * a) Empty the tank completely 3 b) Pressure wash the inside of the tank c) Disinfect the inside using a strong disinfectant d) Punch holes in the bottom to permit future use or accumulation of water. e) Backfill the tank, and soak away pit with compacted sand, gravel, and/or limestone 3 f) If necessary install house connection pipe through backfilled tank g) house connection for watertightness Test h) Restore ground or floor to match surrounding areas.
