This Summary can be submitted to the board of executive directors of the World Bank for review and approval and can be provided to the environment protection authorities, affected groups, non-governmental organizations and wide public as a brief report too. 1.1 Project Background According to the principle of fully and reasonably utilize hydropower resources, Chinese government planned 16-level dams in Han River truck stream and canalized the truck stream of Han River in stairs so as to fully play the comprehensive functions of shipping, power generation, irrigation and flood control of Han River. Among the planned 16-level dams, there are 7 dams in Han River in Shaanxi Province. At present, the 2-level operation has been built in Shaanxi as well as Hubei. According to the order from the upper to the lower, the 9-level dams in Hubei Province are as follows: (1) Gushan; (2) Danjiangkou (built into); (3) Wangpuzhou; (4) Xijin; (5) Cuijiaying; (6) Yakou; (7) Nianpanshan; (8) Huajiawan and (9) Xinglong. The Han River is the main branch of Changjiang River water system, with the advantages of very good natural conditions and regional advantages of developing water carriage and comprehensively utilizing water resources; which is listed as one of the main water carriage channels by Ministry of Communications. According to the objective conditions that Ministry of Communications regards the main water carriage channel of Han River by 2020 as the route goal in the third stage of Ministry of Communications and the development of Han River in stairs, Hubei Bureau of Communications prepared the internal river shipping development planning in 2002 and specified the construction time of each stair, namely: Xinglong in 2009, Huajiawan in 2014, Nianpanshan in 2014, Yakou in 2017, Cuijiaying in 2009, Xinjin in 2014 and Gushan in 2012. In view of comprehensive benefit, the reason why Hubei selected Cuijiaying as the third largest dam in Hubei for construction is that this dam is adjacent to Xiangfan, the second largest city in Hubei; after it is built, it can release the contradictions in the aspects such as irrigation, urban power supply, harbor and water level of the channel and so on in Xiangfan. 1.2 Preparation Basis 1.2.1 World Bank Requirements The World Bank requirements include primarily the Bank's ten safeguard policies, including Operational Policies (OP), Best Procedure (BP), Good Practice (GP) and Operational Directives (OD).   Among these safeguards policies, Environmental Assessment (OP4.01) is the primary requirements and thus will be fully applied in this report and other EA documentation. In addition, other safeguard policies will first be screened during the EA and fully applied if triggered by the screening. Safety of Dams (OP/BP4.37), Natural Habitats (OP/BP4.04), Pest Management (OP4.09) and Forestry (OP/GP4.36) will be applied in this Report too. Involuntary Resettlement and Cultural Property will be applied in by two separate teams. Since there are no project components that involve international waterways (OP/BP/GP7.50), indigenous people (OD4.20) or disputed areas (OP/BP/GP7.60) as defined under OP7.60, policies related to these subjects will not be applied in the report. 1.2.2 National laws and regulations 1). Environmental Protection Law of PRC; 2). Environment Impact Assessment Law of PRC; 3). Land Management Law of PRC; 4). Noise Pollution Prevention Law of PRC; 5). Air Pollution Prevention Law of PRC; 6). Water Pollution Prevention Law of PRC; 7). Solid Waste Pollution Prevention Law of PRC; 8). Water and Soil Conservation Law of PRC; 9). Anti-flood Law of PRC. 2.0 BRIEF INTRODUCTION TO THE PROJECT The Cuijiaying Shipping and Hydropower Pivotal Project is a comprehensive application project mainly featured as shipping one and compromises to generate hydropower with the hydropower generated to promote shipping, its normal 3 impounded level is 63.23m and its corresponding reservoir volume is 285 million m and its installed capacity is 96MW. The total capacity of the reservoir is 10- 1.ox 1 08m3, this project is decided as Class II with Large (2) type scale. The installed capacity of the hydropower station is 50-300MW, the project class is Class III, its scale is middle scale; As for the integrated application water conservancy and hydropower pivot project, the standard specifies that the highest class will govern for the whole pivot project when classification figures belong to several different classes, therefore, this project is classified as Class II. The pivot building is composed of shiplock, hydropower station, sluice gate and earth dam. According to the pivot classification standard, permanent buildings belong to Class II, secondary buildings Class III, and temporary buildings Class IV. The pivot is situated at 17km at the downstream of Xiangfan City of HUBEI Province with control drainage area of 13.06X104 km2, normal impounded level of 63.23m, backwater length of about 39.8km up to Xinji, and it is composed of water release gate, dam, shiplock and powerhouse. 2   1. Water release gate It is of RC lock-and-dam structure, designed as per Class II hydraulic structure, with gate top elevation of 66m, design flood discharge capacity of 19600m3/s and total gate length of 543.2m. 2. Dam It is of clay inclined wall grit shell structure, with the dam top elevation just the same as that of water release gate, top width of 6.5m (communication requirements have been considered) and total dam length of 1324m. 3. Shiplock Its hydraulic structure is of dock structure with lock chamber's effective dimension of 180 X 23 X 3.5m and the design annual maximum trafficability of 1425.6x 1 04t. 4. Powerhouse Its installed capacity is 96MW (5 power generating units) and two circuits of 110kV HV lines are connected with the Xiangfan city power network. Its geographical location is shown in the attached drawing Nol . 3.0 ENVIRONMENT BASELINE 3.1 Physical Environment As located in northern monsoon climate area of subtropical zone, the Han River, enjoys abundant precipitation in spring and summer and limited precipitation in autumn and winter. Statistics show that annual average rainfall is 700-1300mm. The number of days of precipitation reduces gradually to the north from the south, with annual average precipitation days at about 120 days, and the maximum daily rainfall reached 60 - 100 mm. Rainfall distribution is extremely uneven within the year, with the majority concentrated from May to October Annual average evaporation is 900 - 1300 mms in the basin of Han River. It is greater in the lower reaches than in the upper reaches, greater in the river valley than in the mountain areas, greater in the north bank than in the southern bank. The atmospheric pressure is lower in summer than in winter. Evaporation reaches maximum in June or July and minimum in January, February. Annual average temperature in the basin ranges 15-17'C, and 22-34
