Background 1.1.1. Brief introduction of the project "Dongping hydropower project in Hubei Xuanen County", planned to build on the main part of Zhongjian River, which is from Xuanen County to Zhongjian River County on Dongping spot in Hubei Province. Total investment is 0.805 billion RMB, storage capacity is 0.308 billion m3, surface area of the reservoir is 8.12 km2, backwater length is 31.35 km, capacity of the electric station is 102 MW. DONGPING hydropower project prepared ever since 1994, by now it had lasted for 6 years. Major prophase work includes: * 1993.10 Hubei Bureau of Water Resources signed the development plan, which was compiled by Hubei Design and Exploration Academy of Hydropower Institute. 1993,12 Hubei Planning Committee agreed to start the prophase work of the DONGPING hydropower station. * 1996,1 Hubei Planning Committee examined and approved the feasibility study report of Dongping hydropower station. * From 1997, started to prepare the prophase work. e 1997.9 Hubei Bureau of Water Resources examined the water and soil conservation scheme of the project. i 1998.12 Hubei Design and Exploration academy of Hydropower Institution completed the technique design work. * 2000.6 compiled the resettle plan report. 1.1.2. Environment assessment (EA) work progress The EIA (EIA) started from 1999, according to the domestic EIA progress, major works had been done as follows: * 1995.9 Hubei Research Institute of Environmental protection completed the outline of the EIA, which was signed by Hubei Bureau Environmental protection * 1996.5. Hubei Environmental Protection Bureau proved the Environmental Impact Report, 1996, 12 the report was completely finished. 1.1.3. Origin of the assignment Since the project planned to use the loan of World Bank (WB). the EIA should meet the requirements of the WB. According to the suggestions' raised by the WB in 2000. Feb. llu Bei Planning committee entrusted CRAES to take the consulting business of the project, which is emphasizing on providing a supplement for the Environmental Impact Report. Based on the Environmental impact report2 proposed by the Hubei Research Academy of Environmental Sciences, CRAES will do the following work from 2000,4: * To analyze, supply and recompile the content of the work according the suggestions and requirements proposed by the WB, and to contact the project company to prepare the relevant information. * To support the fieldwork including exploring the location of the dam site, gathering 'Consults the revising opinions for the report outline proposed by WB expert Scott Henna, 2000/06/22. 2 Consults the revising opinions for the report content proposed by WB expert Scott Henna, 2000/09/02. .] .  EIA Report on Dongping Hydropower Project Chapter I Executive summary biological samples, collecting supplementary materials and carTyingout several kinds of consulting and surveying work. To recompile the Environmental Impact Report based on the supplementary work and on the discussion with the experts of WB about modifying the outline3 and the report content4. According to the domestic approve-procedure and the WB's requirements, the supplemental modification and the recompiling report should be in both Chinese and English. Also should be submitted to the delegates of WB and representatives of Chinese govemment to examine the Environmental Impact Report. 1.2. The EIA Classification and Purpose 1.2.1. The EIA Classification According to P.R.C. "Circulation on strengthening the management of EIA of the construction project financed by the international financial organization" andthe rules of the World Bank OP4.01 concerning classification of the EIA, averagewhile according to the characteristics of the proposed project, the project of Hubei Xuanen Dongping hydropower project was ascribed to the category A. 1.2.2. Compiling objective TIhe objectives of compiling this report are as follows: Based on analyzing the environmental conditions of the water area and reservoir region, impersonally assess the positive and negative impact on the natural environment and social environment; propose suggestions and measures to rationally utilize the positive impact and mitigate the negative impact; make conclusion on the long term and short-term impact of the project; propose environment inspection and management plans, and provide scientific foundation to further fulfill the project.(evaluating loans, compensating the implement of the activity and implementing the project) 1.3.
