Project Objectives The objective of the Zhejiang Urban Environment Project (ZUEP) is to enhance the efficiency and equity of waste management in Ningbo and Hangzhou municipalities and the redevelopment of the historic inner city in Shaoxing and Cicheng, and thereby facilitating the sustainable development of these cities and establishing a model for conservation of cultural heritage in other Chinese cities. The project will support measures to increase the utilization of waste treatment facilities, increase sewerage services in underserved areas including the fast-growing suburban areas and satellite towns in Ningbo; and to improve waste management institutions and finances through implementation of utility reform measures. Public Disclosure Authorized Redevelopment of the historic inner-city and conservation of build heritage in Shaoxing and Cicheng is a top priority of the municipal governments and the project will contribute to improving the quality of life of their citizens, sustain their cultural and historic nature through tourism development, upgrade their housing stock and safeguard environmental conditions. 3. Project Description The project in the three municipalities of Ningbo, Shaoxing and Hangzhou consists of a mixture of environmental infrastructure services, urban redevelopment and cultural heritage conservation components, along with associated technical assistance. Original Project Components: (a) South Jiangdong Sewerage and Treatment Plant (b) Zhenhai Sewerage and Treatment Plant (c) Cicheng Infrastructure Development (d) Dongqian Lake Development (e) Shaoxing Historic City-Center (f) Hangzhou Landfill Expansion (g) Services, Training and Implementation Support In light of loan savings occurring during project implementation, the following two components were added to the project. Both support the original project development objective: (h) Shaoxing: Yue Kingdom Historical Area Preservation/Rehabilitation (i) Ningbo: Jiangnan Wastewater Treatment Plant and associated sewers The ISDS is being updated to reflect the addition of the two new project sub- components. 4. Project Location and salient physical characteristics relevant to the safeguard analysis Zhejiang Province (population 39 M) is one of the most important of the eastern coastal provinces in China. It is an integral component of the Yangtze Economic Zone and has a strong industrial sector and prosperous agricultural base. Hangzhou (urban population 3.7 M) is the provincial capital and has an important geographical location on the N bank of the Qiantang River at the apex of Hangzhou Bay. The city is a major tourist destination, a major attraction being the famous West Lake. Waste generation in the city is increasing rapidly, in part due to improvements in collection, and there is an urgent need for new disposal facilities as the existing landfill is nearing completion. The project proposal is to extend the existing well operated landfill, located in a small valley some 18 km N of the urban center; this option was selected in preference to 8 potential new landfill sites elsewhere on grounds of lower incremental environmental impact. Ningbo (urban population 1.26 M) is an important port and industrial center located at the estuary of the Yongjiang River. The urban center of Ningbo and the outlying township of Cicheng are traversed by a number of small rivers, which currently receive large wastewater discharges. Dongqian Lake is located about 15 km from the Ningbo urban center and is the only major scenic area for Ningbo. There are proposals to expand tourism in the lake area, but the lake is also an important water source for urban supply and agriculture. Existing and potential further pollution threatens these beneficial uses. Shaoxing (urban population 0.5M) is in the NE of Zhejiang and is one of the key cities in the Changjiang River delta. The city has a long history and has been the regional political, economic and cultural center since ancient times. Much historical and cultural heritage and many historical street areas are still well preserved, and the old city has a network of canals fed from the moat that surrounds the city. Areas adjacent to these canals in the historic areas of the city house in the order of 30 000 people, but urban services are poor and properties lack basic water, sanitation and energy supply facilities. The project would directly benefit about one million people through improved water supply, wastewater and solid waste collection and disposal, energy supply services, housing in the historic city centers, roads and transportation, flood control, and recreational facilities. A small number of people will be directly affected by the project because of resettlement and enterprise relocation from crowded inner-city locations and displacement by construction activities. The project components in Shaoxing and Cicheng are located within culturally sensitive areas but issues are adequately dealt with because of the heritage conservation approach with these components. Dongqian Lake project component is located within an environmentally sensitive area. 5. Environmental and Social Safeguards Specialists Mr Songling Yao (EASCS) Mr Feng Ji (EASCS) 6.

Key Safeguard Policy Issues and Their Management A. Summary of Key Safeguard Issues 1. Describe any safeguard issues and impacts associated with the proposed project. Identify and describe any potential large scale, significant and/or irreversible impacts: Existing Project Components. The environmental impact of the project is expected to be on balance substantially positive in terms of improved water quality in the rivers and canals in the urban areas of Ningbo (and surrounding towns) and Shaoxing and of improved and sustainable wastes management in Hangzhou. There are, however, some significant impacts in Ningbo/Shaoxing and in Hangzhou. The quantities of sludge requiring disposal will continue to increase as a consequence of population growth, increases in the wastewater treatment rates in Ningbo and the potential future further centralization of wastewater treatment. Accordingly and in light of the limited space of sanitary landfills, Ningbo Municipal Government approved in October 2008 the Ningbo Municipality WWTP Sludge Treatment Master Plan which called for incineration of all WWTP sludge at thermal power plants in the city by tapping surplus heat in thermal power plants to dry dewatered sludge before incineration. In accordance with this Master Plan, South Jiangdong WWTP and Zhenhai WWTP began to send their dewatered sludge to thermal power companies approved by local EPB for incineration. An assessment is ongoing to confirm that the sludge is disposed of in an environmentally sound manner. In the case of the Tianziling landfill in Hangzhou, although the facility will meet international standards of sanitary landfill, there will be the inevitable potential impacts of leachate and landfill gas generation. Each will occur throughout the lifetime of the site and in the case of gas generation for a considerable period thereafter. The potential impact of leachate in terms of groundwater contamination will be mitigated by means of a comprehensive site liner and collection and treatment of leachate. The impact of gas generation will be mitigated by forced extraction of gas with beneficial use of the gas for power generation. Rates of waste generation in Hangzhou, and therefore potential deposition at the Tianziling landfill site, will increase due to population growth and increases in the wastes collection service area. Such an increase would reduce the operating lifetime of the site, but at the same time there are proposals to increase the current low recycling rates for waste stream components, which will have the effect of increasing the site life. An increase in waste deposition rates may increase gas generation rates, but the overall period of gas generation
