Environmental Impact of the Project and Mitigation Measures Summary 4.1 Environmental Impact Assessment In the implementation process of environmental impact assessment, the layout of the project, the main environmental protection objectives in surrounding assessment range and the sensitive points are identified (see the Figure 4.1-1), the possible adverse environmental impacts caused by the project are as follows: Impact on the hydrology and sediment Hydrological changes Impact on regional water resource In the Cheng County Moba gorge water supply project, water is stored in a reservoir, wherein the normal water level of the reservoir is m, the total capacity is1.79 million m3, the backwater length is about 3.5 km, and the designed reference water is million m3/a. In running period, the downstream of the dam comprises a diversion effect river section of 4 km Ecological water of river and mitigation measures When the reservoir of Moba gorge is completed, the inflow of Nan River over the dam (the basin area is km2) is retained, and the mean runoff of many years is 1.22 million m3 when the reliability is 95%. The ecological water use of the river is calculated according to the Tennant method recommended by the Environmental Impact Assessment Specification of River Basin Planning, in which the ecological water use of Nan River is the minimum, namely about 10% of the annual average flow as the minimum use of ecological water, and according to the calculation of the method, the minimum ecological water use of Nan River is m3/s. Thus, the ecological water of the diversion effect river section is ensured, and the dam should be provided with permanent plug holes while construction. The plug hole should lower than the water inlet while higher than the flood discharge sand flushing port, specifically the elevation is 1024 m-1065 m, the discharge amount is m3/s, thereby ensuring the minimum ecological water use of the diversion effect river section Impact on the diversion effect river section Due to the abouchement of Nan River from the Fengquan River downstream the dam of 4 km, and the normally annual runoff of the Fengquan River is 2.06 million m3, it can be determined that the diversion effect river section is 4 km. The section comprises eight villages, i.e. Zhuanwancun, Ganlushi, Majiaya, Jianjiagou, Xiaozhuang, Zhangjiashan, Luangoumen and Niujiaya. Zhuanwancun comprises about 900 people or more, Ganlushi comprises about 1000 people or more, Majiaya comprises about 300 people or more, Jianjiagou comprises about 350 people or more, Xiaozhuang comprises about 250 people or more, Zhangjiashan comprises about 600 people or more, Luangoumen comprises

28 about 100 people or more, and Niujiaya comprises about 120 people or more. The water of the eight villages is mainly supplied from the local mountain spring and groundwater which are not the water in the river section, so that the impact of the project to the water source is controllable. The ecological water use can be ensured in case of the discharge flow ensured is m3/s.
