Introduction 1.1 Background Phase I of Danang- Sanitation Project xvas approved by Governmileit of Vietnam in Decision No 414/QD-TTg dated April 20, 1999 with total investment of about USD 41 million. Pliase I wvill support improved sanitation services to 33 phuongs in Danang's five ulbanl districts. Kev drainage and wastewatcr works supported by tile Phase I include: * installation of gravity interception drains (GlDs), connections and rising mains; * construction1 of drv weathier tiow diversion strUctUres within major existing drains; * installation of submersible purnp stations; * installation of primary treatment plants (F1oa Cuong, Phlu Loc, NguL Haanil Son, and Son Tra) with capacities ranging from 3.7 to 45 M'IL/day; * construction of major drains in critical areas in Danang; * construction of public toilets, some of whiich are incorporated into solid waste transfer stations; and * implementation of comnmunitv based sanitation improveinenit programs involving community educationi programs. The construction of Pliase I works is currently underway and is expected to bring substantial net benefits to Danang city. Due to savings generated through Phase l's bidding process, about 11 USD million of additional drainagre and wastewater works (hereafter known as the Additional Works Project) have been approved both bv World Bank (in Aide M\e[emoire of April 2, 2002) and Danang Peoples' Committee (in Decision No 1450/VP of April 11, 2002). A feasibility study for the additional works was prepared in the second half of 2002. The final version was completed in November 2002. CivMC was assigned to prepare detailed designs for all additional works. A start with design activities was made in Februa-y 2003 and this EIA report is part of the output of the engineering studv. 1.2 Preposed Drainage and Wastewater Improvement The majority of Project funds will be tised to support drainage works (USD 7.6 million). Wastewater works are the Project's second budgetary prioritv (USD 1.6 million), and beach cleaning is a tertiary priority (USD 0. 1 million). The remaining funlds are allocated to consulting fees, contingencies, and taxes (USD 1.7 million). 1.3 Proposed Drainage Works Thle Project wvill construct drainage: I) in Binil lThliain ward fiom Le Dinii Tham to LDuy Tan Roacl; 2) fiom Dien Bien Phu Steet to Danang Bay thlloLlgl Le Do Street; 3) fiom Dien Bien PIhu Steet (Xuan H-oa pond) to Trani Cao Van Street (PlItI Loc River); 4) fi-om An KhCe pond to Phu Loc River; and 5) ftroim i9v Khe to Bac tle AAn.

Potential Environmental Impacts of the Project 2.1 Summary of Impacts The EIA evaluated a range of potential impacts that could occur as a result of the Project. The selection of potential impacts for evaluation was based on site visits, discussions with Phase I project staff, URENCO, DoSTE and others; and through review of relevant documents such as World Bank's Environmental Assessment Sourcebook, Phase I environmental assessment reports, the Project's Feasibility Study and others. Table I provides a summary impact evaluation of potential impacts that could be created by the Project. These impacts are further detailed in the EIA Report. Table 1: Summary of impacts.

The impact of these activities on affected persons (resettlers, land owners) is loni term and permanent. Tlle Project is developin(g a detailed Resettlement Action Plan (RAP). Thle RAPs objectives include: 1) providing recommendations to minimise resettlement and land acquisition; and 2) provide fair compensation schemes for those whose land, hoQLues, cultural property, and graves must be purchased or relocated by the Project. The RAP is a stand-alone document that can be used as a reference for further details on impacts identified in this section. 2.2 Construction Phase Impacts Construction phase impacts are generally short term, localised, and reversible. As with most urban civil works projects, constrLction phase impacts usually have negative human health, safetv, and environmental consequences. This section identities the most likely impacts that will arise durinig construction, and provides both mitigation objectives and measures to achieve those objectives. As described below, many of these measures can be directly inserted into Contractor Specifications. This will help ensure that the measures are woven into the norrnal scope of Project works, that the measures can be monitored, and that if the measures are not achieved, then there is a means to apply negative consequences to the delinquent partv (in most cases, the Contractor). 2.3 Operation Phase Impacts Operation phase impacts will be long term and cumulative. As the Project is essentially a set of urban environmental mitigation measures, the operation phase impacts are almost entirely positive. Construction Management Consultants Page 5 DHV, CDM and VIWASE Vietnam Three Cities Sanitation Project Additional Works Project - EMP Danang Sub-project August 2003 3. Environmental Mitigation Plan 3.1 Approach to Developing Mitigation Measures When constructing the mitigation measure tables of Section 3, the following points were considered: * Mitigation measures for negative impacts identified in Section 2 (regardless of their magnitude) are considered in Section 3 tables. * Construction mitigation measures are, whenever possible, woven into the construction specifications. This enables the Engineer to have significant authoritv over the implementation of mitigation measures. * "Environmental Best Practices" will not be made explicit within the Contractor Specifications. This in line with the general approach to seamlessly integrating environment into contract management and civil works projects in general. * If a measure was considered to be ineffective during Phase I (e.g. spraying roads with water to reduce dust) alternate mitigation measures were considered. * Costs that WLould be borne by the Contractor are not identified in this table -these costs will become part of ihe competitive bid of contractors. Costs of resettlement and land acquisition will be identified in the Resettlement Action Plan.

Environmental Monitoring The Project's performance and environmental effects will be monitored throughoult pre-construction, construction, and operation. Performance monitoring is conducted to evaluate compliance with standard operating procedures (SOP), national standards, and/or contractor specifications. In most cases performance monitoring results are evaluated against established performance criteria. For example: I) a Contractor specification may be to place a tarp over all vehicles that carry soil. The performance monitoring activity could be to count the number of soil-carrying vehicles that use tarps, and compare the result against the Contractor Specification; 2) Wastewater effluent may be monitored and compared witi national standards for xvastevater quality. Environmental effects monitoring is conducted to estimate the impacts of project activities on ambient environmental conditions. For example, total suspended particulate matter (i.e., dust) may be measured to estimate the degree to which project activities are affecting ambient air qualitv; 2) Fecal coliform levels in the river may be measured to estimate the impact of wastewater effluent on the river water quality. In both cases, it is recommended that URENCO's Environmental Mvfonitoring Team play the primary role in managing and implementing Project monitoring activities. This team has received substantial training and experience on environmental monitoring through Phase I project and they should be able to conduct most of the tasks identified in the below table with some occasional guidance from an international environmental specialist. Detailed monitoring programmes should be developed during Pre-construction. The tables in this section can be used as a guide to develop the detailed monitoring programmes Construction Management Consultants Page 15 DHV, CDM and VIWASE Vietnam Three Cities Sanitation Project Additional Works Project - EMP Danang Sub-project August 2003 MONITORING PLAN What Where How When Why Cost Responsibility parameter is to be is the parameter to is the parameter to be is the parameter Is the parameter to be monitored? be monitored? monitored! type of to be nmonitored? monitored? equipment?

Institutional Responsibilities This section identifies responsibilities for mitigation and monitoring, environmenltal information flow, and decision-making chains of command.3 5.1 Pre-Construction Phase Responsibilities 5.1.1 URENCO URENCO will ensure design capacity of pumps, weirs, outlets and chaniiels is adequate to redirect the vast majority of wastewater to the wastewater treatment plants. URENCO will be responsible for managing both environmental effects and project performance monitoring during Pre-construction. URENCO will review and comment on Contractor's Site Environmental NManagement Plan. 5.1.2 Contractor Contractor will be responsible for developing a Site Environmental Mfanagement Plan (SEivMP). SEMP will be based on issues presented in EM\[P and any other issues deemed relevant to the environmental management of the Project. Contents could include: * purpose of the Site Environmental Mvlanagement Plan; * project background; * regulatory framework for environmental protection during construction; * potential significant impacts during construction phase; * mitigation Measures that to address potential significant impacts; * monitoring the effectiveness of the mitigation measures; * resolvino environmental impacts created by construction activities; * experience and qualifications of environmental monitoring team; and * reporting format and schedule. SEvIP must be approved prior to the initiation of construction phase activities. 5.1.3 Engineer Engineer will review, comment on, and approve Site Environmental Management Plan. 5.2 Construction Phase Responsibilities 5.2.1 World Bank World Bank will review the implementation of the SEMvP. Problems identified will be raised to Danang People's Committee, URENCO, the Contractor, the Engineer-, and other relevant bodies as part of the regular project review process. 5.2.2 Danang Peoples' Committee Danaing People's Committee has overall responsibility for managing provincial administrative bodies, including DoSTE, Danang Urban Transport Division, and URFENCO. Institutional responsibilities relating to lancd acquisition, resettleimcit. and cultural artifacts are otuncl in the Rescttlement Action Plan. Construction Management Consultants Page 24 DHV, CDM9 and VIWASE Vietnam Three Cities Sanitation Project Additional Works Project - EMP Danang Sub-project August 2003 5.2.3 Danang DoSTE Danang DoSTE will represent MvoNRE as environimenital regulator." DoSTE will be responsible for advising the Project of any contravenltionl to Vietinam's environmental management anld protection policies. They will also plav a key role in the assessment of any unforeseen designi chlaiges which may create environmental effects. 5.2.4 Danang Urban Transport Division Danang Urban Transport Division will provide support for URENCO to conduct its environmelntal management duties. 5.2.5 Project Management Unit The P.IU will assist with co-ordination of mitigation measures implemented during the constrLction phase. 5.2.6 URENCO UR-ENCO will be responsible for ensuring that any recommendations to improve on how to improve environmental protection and sustainability will be integrated into the Project. URENCO will be responsible for managing both environmental effects and project performance monitoring during Construction. 5.2.7 Engineer Engineer has key responsibility for overseeing the quality of works conducted by the Contractor. Engineer holds key decision making tasks related to the SEivP, including: assessing compliance with contract environmental clauses, decisions to stop work or withhold payment from contractors for non- compliance withi contracted environmental agreements (methiod statements, conditions of contracts, contractor specifications, etc). Engineer Site M'vlanager will conduct on-site monitoring of performance mitigation measures proposed by thie SEivlP (i.e. ensure contractor activities are being conducted as per contractor specifications). They will report their findings in regular reports to the Eng,ineer as part of their regular duties. 5.2.8 Contractor Contractor will implement all environmental protection and mitigation measures in the SEMP, contractor specifications, and other relevant documents. The Contractor may assign a Control Engineer to conduct on-site management of the EiMvP. Control Engineer's tasks could inclLide: ensuring all supervisors and workers are fully aware of the relevant EMv[P procedures, all surveys are carried, necessary records taken, advise management of any problems or potential environmental problems encoulitered. Contractor will submit SEivMP reports to the Engineer every three montis. If, for any reason, the Engineer, URENCO, the World Banlk, DoSTE, Danang, PC, or the Contractor deem mitigation measures proposed in the SEMP to be ineffective, the Construction Contr-actors will need to proposed new/improved mitigation measures. 4Due to administrative restructuritig. DoST'E will split into Department of Sciciice anid Tecihinology (DoST) andi Department of Environnmet atnd Na[ural Resouirces (DoNRE) in late 2003 or eairli 2004. AfIter restructurinie. DoNRE will likely assumie DoSTE's environmental management responisibilities.

Construction Management Consultants Page 27 DHV, CDM and VIWASE Vietnam Three Cities Sanitation Project Additional Works Project - EMP Danang Sub-project August 2003 6. Capacity Development for Environmental Management 6.1 Pre-Construction and Construction Phases Capacity Building Requirements of the Contractor The Contractor's Site Environm1enital Nlanagement Plan (SEMIP) should include a section on safety, hygiene, and environment training for appropriate staff members, sub-contractors, and constrUction workers. If URENCO notes lapses in worker standards for safety, hygvienie and environment after tihe scheduled training occurs, URENCO shoLIld instruict the Contractor to make provision for further training of selected individuals. Capacity Building Requirements of URENCO Due to a recent restructuring of URENCO and Phase I PLvIU, URENCO's current capacity to manage ENIP activities during pre-constrUction and construction of the Additional Works Project is relatively low. Selected URENCO staff wyould benefit from a qualified international environmental specialist who can provide appropriate capacity development assistance. The international environmental specialist's assistance should focus on providing "learning by doing" guidance on design, management, and reporting of the EivlP's pre-constriction/construction monitoring and mitigation, activities. The estimated level of effort for an international environmental specialist durinig pre- construction and construction is three months. 6.2 Operations Phase Capacity Building Requirements of URENCO As with pre-construction and construction, URENCO's currenlt capacity to manage EMvP activities during operation is relatively low. Selected URENCO staff would benefit from a qualified international environmental specialist to provide "learning by doing" guidance on the management and reporting of operations phase monitoring and mitigation activities identified in the EIP. The estimated level of effort for an international environmental specialist during operation is one montlh.

Costs of Implementing the EMP This section estimates the marginal costs for condUCting the EMP's main SLub-components: mitigation, monitoring, and capacity building. Costs that are inCLirred by other project components but satisfy some aspect of thie EMP are not inciluded in this section. Thle division of costs between URENCO and IDA funids was developed in conisultation with URE-NCO PMU Director. Thie total marginal cost of the EMP from Pre-Construction throughl to the end of the first year of operation is 117,700 USD (not inCiLuding continigencies, taxes, or inflation). This amouint is abouIt 1.07 % of the project's estimated USD I1I million buidget. EMP costs can be broken down as follows: Pre-Construction ('31,800 USD);- ConistruICtion: (64,200 USD); and Operation 21,700 USD (Year 1); and 3,1 00 USD (Year 2 onwards).
