machinery, workers’ activities (60 workers), and impacts at the proposed borrow pits Domestic solid waste generated by construction workers, construction campsite, kitchen, toilets. Improper disposition of hazardous wastes such as waste oil, spent lubricant, and contaminated materials resulting from leakage of oil and fuel. Improper handling and storage of hazardous and chemical substances and construction materials. Erosion at borrow pit and the dyke site affecting irrigation canals and paddy rice fields. Temporary increase in volume of the local traffic system due to increasing traffic and Generation of solid and liquid waste; increased use of local resources; potential conflict between workers and local people; health issues and social evils. 3. Operation phase 3.1 Risk due to in appropriate operation of culverts and/or inadequate maintenance of the dyke May local flood and possible impacts on water quality and water uses. Small, can be mitigated during detailed design. Institutional capacity building component could help reducing the risk 3.2 Risk due to increasing local flood due to increasing high of the dyke Potential increase in damage due to flood event Low, can be mitigated through community engagement activities Social impacts and mitigation measures Table 4.3 summarizes the amount of land required and affected households, while the final affected land and pollution will be determined during the detailed design. Mitigation of these impacts will be in accordance with RAP of the subproject which has been prepared in line with the RPF and will be submitted for WB clearance. Details are provided separately.

Provincial Environmental staff (ESU) and Provincial Environmental Management Consultant (PEMC) Assist PPMU in the implementation of the EMP, including training of engineers and supervision of contractor monitoring and water quality monitoring. CSC and/or Field engineer Assist PPMU in the day-to-day supervision of contractor performance in line with the ECOP, including reporting and maintain close coordination with local community. Contractor Take actions to mitigate all potential negative impacts in line with the objective described in the ECOP and the approved CSEP. Actively communicate with residents and take actions to prevent disturbance during construction. Ensure that at least a staff is assigned to monitor the CSEP compliance during the site clearance and construction periods. Ensure all the construction activities having sufficient documents from the related organization. Ensure that all and workers understand the procedure and their tasks in the environmental management program. Report to the PPMU on any difficulties and their solutions Report to authority and PPMU if environmental accidents occur and coordinate with agencies and keys stakeholders to resolve these issues Local community Community: According to Vietnamese practice, the community has the right and responsibility to routinely monitor environmental performance during construction to ensure that their rights and safety are adequately protected and that the mitigation measures are effectively implemented by contractors and the PPMU. In case of unexpected problems, they will report to CSC/PPMU. Union and other mass organizations These organizations could play a role as a bridge between the PPC/DPC, communities, contractors, and PPMU by assisting in community monitoring, Mobilizing communities participation in the subproject, providing training to communities, and Participating in solving environmental problems if any. Province and District People’s Committees (PPCs/DPCs) Oversee the implementation of the subproject under the recommendations of the DONRE and the PPMU to ensure compliance of Government policy and regulations Provincial DONREs represents the MONRE for environmental management. It is responsible for monitoring the compliance with the Government environmental requirements. Monitoring and Reporting
engineer and construction supervising consultant will report the safeguard performance of the contractor as part of the contract's progress report to the PPMU. The PPMU will submit a progress report to CPMO periodically, including the progress on the implementation of the safeguard performance of the contractor and the progress on the CEP implementation. CPMO will submit the following reports to WB: (a) Semi-annual progress report, including; (b) Mid-term Review Report; and Annual Environmental and Social Safeguard Monitoring Report, and the reports will also include the progress on safeguard implementation and performance of contractors. Frequency of reporting is illustrated in the Table 6.2 below. Table 6.2 Subproject reporting requirements Type of report Frequency Responsible Reporting to Report on the subproject’s progress on compliance with mitigation measures, clearly demonstrating activities to comply with EMP at the construction site and monitoring results. Monthly Construction Supervising Consultant of PPMU PPMU EMP implementation report, clearly demonstrating activities to comply with subproject EMP and monitoring results. Once every six months during the construction stage Construction Supervising Consultant of PPMU PPMU Environmental monitoring reports, clearly demonstrating environmental impact monitoring process and results. Once every six months Construction Supervising Consultant of PPMU PPMU Community Monitoring on implementation measures by contractor (if available) If any complaints Community PPMU Subproject environmental management reports, demonstrating the overall subproject environmental activities and activities to comply with EMP Upon subproject completion PPMU CPMO, province Table 6.3: Tentative workplan for Subproject Activities Responsible entity Work schedule Remarks 1.
