Environmental impact:
|
Screened B/1. The project is expected to have significant positive environmental impact due to improved quality and efficiency of water supply and sewage services in the City of Volzhski. The environmental due diligence is a part of the Feasibility Study and brings forward environmental considerations, which are taken into account during the selection of the priority investment components.
Environmental Review Summary
1. Description of the project
Volzhski Municipal Water Services Company “Volzhsky Vodokanal” has requested the European Bank of Reconstruction and Development (the “EBRD”) to provide financing in support of their priority investment programme (PIP) to improve the quality and efficiency of drinking water supply and sewerage treatment services in Volzhski City. The Project is designed to address the main safety and environmental problems existing to date and includes the following investment components:
1) Construction of drinking water supply main from the 3rd lift pumping station (PS) to the 4th lift PS alongside the already existing pipeline;
2) Reconstruction of the chlorination unit at the 3rd lift PS;
3) Reconstruction of the 3rd line wastewater treatment plant (WWTP), including reconstruction and extension of the WWTP, reconstruction of the existing sludge beds and construction of the mechanical dewatering unit.
2. Environmental classification and rationale
The EBRD has classified the project B/1. The project is associated predominantly with the rehabilitation of the existing structures. This will result in limited adverse environmental and social impacts and in significant environmental benefits, which can be readily identified and quantified by means of an Environmental Analysis. As the existing facilities are involved, an Environmental Audit has also been undertaken.
3. Information reviewed during the environmental appraisal
The environmental appraisal has been based on the review of the Environmental and Technical Due Diligence Report of Volzhski Water Project, prepared by independent consultants from COWI in June 2008 in accordance with the requirements of the EBRD Environmental Policy (2003).
4. Environmental and social issues
The environmental due diligence revealed that Vodokanal developed a sound EHS management system and its operations are generally well organized and managed. The existing environmental, occupational health and safety and labour practices are mostly compliant with the applicable Russian laws and regulations. Major issues of environmental concern for Vodokanal are related to drinking water supply, wastewater treatment and sludge management. Water distribution and sewerage systems of the Volzhski City are considerably worn-out, and significant part of the existing equipment and facilities are in need of urgent modernisation. Corrosion of the network pipes leads to high level of leaks and water losses as well as to significant capital expenditure to maintain drinking water quality and stable water supply. Increased quantities of chemicals used for the purpose of water purification and treatment creates high potential for secondary contamination. The existing system of secondary chlorination at the 3rd lift PS is not compliant with the national safety requirements and presents a hazard to the environment and health. Existing wastewater collection and treatment in 1st and 3rd WWTP line is inefficient, their capacity is overloaded, and current wastewater treatment technology results in high levels of polluting substances being discharged into the watercourses. High effluent load in wastewater is to large extent a result of highly toxic discharges from some of the major industries based in Volzhski City. Finally, sludge is currently discharged onto sludge beds without any treatment, and the existing sludge beds are worn-out and do not have enough spare capacity to provide stable operation of the WWTP.
The project’s PIP measures are designed to address the most urgent environmental, occupational and public health and safety concerns revealed during environmental due diligence and they will support key improvements to water main, chlorination unit and existing WWTP. The PIP has been structured to meet Russian and EU environmental standards, and adequate mitigation measures have been incorporated in the project design and into the resulting Environmental and Social Action Plan.
The environmental investigations showed that the project would result in significant environmental, health and safety improvements, and that any adverse environmental impacts would be limited. Implementation of the PIP will provide a number of benefits including increased reliability of water supply services for the city, mitigation of risks associated with operation of the chlorination unit, increased capacity of wastewater treatment plant to ensure stable sanitation services for the growing city, increased quality of wastewater treatment, and mitigation of negative impacts of stored sludge on soil and groundwater by introduction of safe and reliable sludge management system. The operation will significantly contribute to decreasing the level of polluting discharges into Volga tributaries and the Caspian Sea basin.
There are no adverse impacts associated with the implementation of the PIP. Construction-related impacts are likely to be localised, short term in nature and they will be efficiently prevented or mitigated by applying international construction practice and planning. Any negative impacts and risks revealed can be fully mitigated through thorough implementation of the Environmental and Social Action Plan.
5. Summary of mitigation measures
A comprehensive Environmental and Social Action Plan (ESAP) has been developed to help Vodokanal implement the Project in the environmentally sound and sustainable manner. The ESAP has been structured to bring the facilities and the Company’s environmental performance into compliance with EU environmental, health and safety standards. The ESAP includes measures for managing and mitigating the impacts of the construction activities and operation stage of the Project, and guides Vodokanal to enhance the performance of its drinking water services, wastewater treatment facilities and sludge management operations.
6. Disclosure of information and consultation
Environmental information on the project will be disclosed to public in accordance with the planning and construction procedures of Russian law. In the context of EBRD’s participation in the project, this environmental summary will be disclosed locally at Volzhsky Vodokanal offices and local media as well as in English on EBRD website at www.ebrd.com
7. Monitoring and Reporting
Volzhsky Vodokanal will report to the EBRD annually on the measured environmental impacts and on the implementation of the ESAP. The Bank will evaluate the project's compliance with the applicable environmental and social standards during the lifetime of the project by reviewing these reports and by conducting monitoring visits to the project when and if deemed appropriate.
