973-2290.004 EXECUTIVE SUMMARY Introduction The East China Electric Power Group Corporation (ECEPGC) is proposing to construct the East China/Jiangsu 500 kV power transmission project to increase transmission capacity between the northern and southern regions of Jiangsu province. The project includes the addition of more than 993 km of transmission line, the construction of nine additional substations, and the expansion of two existing substations. The project spans the Province of Jiangsu, which includes the municipality of Nanjing, and traverses a small area within the independently administered provincial level city of Shanghai. The load center for the Jiangsu power grid is currently in the south of Jiangsu Province. The existing transmission system cannot satisfy this increased capacity. As a result, the Ninth Five-Year Plan includes a recommendation to increase power capacity north of the load center and, in some cases, outside of the province altogether. Therefore, the Jiangsu Provincial power grid is an important component of the East China Power Network, comprising a critical point in the transfer of electric power within the network. ECEPGC worked closely with provincial governmental organizations responsible for power development, planning, and environmental protection for siting of transmission line components and design and development of the overall line. In addition, project sponsors consulted with numerous local governments (i.e., villages and townships) to ensure that the input of local communities was incorporated into the siting of the transmission line route and substations. As a result of these consultations, the development of the project occurred within a participatory framework that involved all levels of government. In preparation for the project, engineering design, feasibility studies, and site/route selection studies were conducted by ECEPGC, Jiangsu Provincial Electric Power 1:\97\2290\2290CHNA.FNL Golder Associates May 1998 ES-2 973-2290.004 Corporation (JPEPC), East China Electric Power Design Institute (ECEPDI), and Jiangsu Electric Power Design Institute (JEPDI). ECEPGC contracted the Nanjing Environmental Research Institute (NEPRI) to conduct an environmental impact assessment (EIA) of the proposed project for submittal to the relevant Chinese authorities. Goider Associates, Inc., an environmenta1 engineering firm located in the United States was contracted to work with NEPRI to prepare an environmental assessment (EA) report for submittal to the World Bank as part of its application for financing the project. This report represents the combined efforts of NEPRI and Golder Associates to produce an EA report in strict accordance with both PRC and World Bank requirements. Description of Project The proposed project includes two principal components. The first component, referred to in this report as the rural component, involves the necessary upgrades to the transmission line system from Shanghai to Renzhuan in Jiangsu Province, including the addition of five 500 kV substations, upgrading two 500 kV substations, and the addition of approximately 993 km of 500 kV transmission line. The second component, referred to in this report as the urban component, involves the necessary upgrades to the transmission network in Nanjing, including the addition of two 220 kV substations, two 110 kV substations and the addition of 10 km of 220 kV transmission line. The rural component traverses nearly 1,000 km of Jiangsu province countryside, in China's eastern coastal region. Jiangsu province has a mild temperate climate, with an average annual temperature of 13 to 15.6 'C. The area north of the Huaihe River and Jiangsu general irrigation channel has a climate characterized as humid and semi-humid temperate, while the areas south are considered humid subtropical. The average annual rainfall in the 1:\9Y\2290\229WCHNA.FNL Golder Associates May 1998 ES-3 973-2290.004 province is between 800-1,150 mm. Prevailing wind direction is to the east, with annual average velocity of 3 m/sec. As with most of China, long-term conversion to urban and agricultural use has virtually eliminated the region's natural vegetation. With the exception of lakes, rivers, and coastal marshes, the landscape traversed by the rural component of the proposed transmission line network is now occupied by a dense mosaic of agriculture, irrigation/flood control networks, agroforestry plantations and urban/industrial zones. Virtually no natural stands of terrestrial vegetation exist; native flora persist only within protected areas or wetland margins. Nevertheless, aquatic environments, including the Yangtze River and Yancheng Marshes are important for the conservation of numerous threatened and endangered species. Regionally, wetlands are associated with the numerous freshwater lakes within the meanders of the Yangtze River floodplain. Marshes fringe the lakes, persist in ancient lake beds and river channels, and develop in seasonally flooded areas. In addition to supporting native flora, these wetlands serve as important fishery resources, and as wintering areas for migratory waterfowl. The Yangtze River will be spanned by a section of the rural component. The urban component is to be built in Nanjing, a municipality located in a humid subtropic region with distinct seasons. Recent climatological data indicate an annual average temperature of 15.3
