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 fiilly and reasonably utilize hydropower resources, Chinese government planned 16-level dams in Han River truck stream and canalized the truck stream o f HanRiver in stairs so as to fully play the comprehensive functions of shipping, power generation, irrigation and flood control o f Han River. Among the planned 16-level dams, there are 7 dams in Hail 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 d a m 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 Changjiaiig 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 o f the main water carriage channels by Ministry o f Communications. According to the objective conditions that Ministry of Communications regards the main water carriage channel o f Han River by 2020 as the route goal in the third stage of Ministry o f Coininunications and the development of Han River in stairs, Hubei Bureau o f 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 in2012. 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 i s 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). 1  Among these safeguards policies, Environinental 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 o f Dams (OP/BP4.37), Natural Habitats (OP/BP4.04), Pest Management (OP4.09) and Forestry (OPlGP4.36) will be applied in this Report too. Involuntary Resettlementand Cultural Property will be applied in by two separate teams. Since there are no project components that involve international \caterways (OP/BP/GP7.50), indigenous people (OD4.20) or disputed areas (OPIBPICiP7.60) 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 PollutionPrevention Law of PRC; 5). Air PollutionPrevention Law of PRC; 6). Water Pollution Prevention Law of PRC; 7). Solid Waste Pollution Prevention Law of PRC; 8). Water and Soil Conservation Law ofPRC; 9). Anti-flood Law o f PRC. 2.0 BRIEFINTRODUCTIONTO 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 impounded level is 63.23~1and its corresponding reservoir volume is 285 million 1n3, and its installed capacity is 96MW. The total capacity o f the reservoir is 10- 1.OxlOSin3,this project i s decided as Class I1 with Large (2) type scale. The installed capacity o f the hydropower station is 50-300MW. the project class is Class 111, 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 11. The pivot building is composed of shiplock, hydropower station, sluice gate and earth darn. According to the pivot classification standard. permanent buildings belong to Class 11, secondary buildings Class 111, 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 13.06~10~ kin2,norinal impounded level of 63.231~1, backwater length o f about 39.8k1n 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 I1 hydraulic structure, with gate top elevation o f 66m, design flood discharge capacity of 19600iii3/sand total gate length of 543.21~1. 2. Dam It is of clay inclined wall grit shell structure, with the dam top elevation just tlie same as that of water release gate, top width of 6.5111 (coiiiniunication requirements have been considered) and total dam length of 1324m. 3. Shiplock Its hydraulic structure i s of dock structure with loclc chamber's effective dimension of 180X 23 X 3.5111 and the design annual maximum trafficability of 1425.6~04t. 1 4. Powerhouse I t s installed capacity is 96MW (5 power generating units) and two circuits o f 11OkV HV lines are connectedwith the Xiangfan city power network. Its geographical location i s shown in the attached drawing No1. 3.0 ENVIRONMENTBASELINE 3.1 PhysicalEnvironment As located in northern monsoon climate area of subtropical zone. tlie IHan River, enjoys abundant precipitation in spring and summer and limited precipitation in autumn and winter. Statistics show that annual average rainfall is 700- 1300nim. 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 witliiii the year, with the majority concentrated from May to October Annual average evaporation is 900 - 1300 mms in tlie basin of Hail 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 minimuin inJanuary. February. Annual average temperature in the basin ranges 15-17
