4. 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: 4.1.1 Impact on the hydrology and sediment 4.1.1.1 Hydrological changes 4.1.1.1.1 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 1092.70 m, the total capacity is1.79 million m3, the backwater length is about 3.5 km, and the designed reference water is 1.651 million m3/a. In running period, the downstream of the dam comprises a diversion effect river section of 4 km. 4.1.1.1.2 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 248.2 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 0.138 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 0.138 m3/s, thereby ensuring the minimum ecological water use of the diversion effect river section. 4.1.1.1.3 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 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 0.138 m3/s.

Figure 4.1-1 Location Diagram of Sensitive Points of the Project 4.1.1.2 Impact on Sediment Load and Mitigation Measures The factor impacts the bedload sediment is more. According to the current technology and the test means and equipment thereof, the accuracy of the test data is not high, the relation of push and suspension ratio of the sediment to the various hydrological factors is bad. In the project, the bedload sediment of the region is designed to the 15% of the suspended load sediment by combining with the general relation of the mountain stream push and suspension ratio of 10 to 20%. The annul bedload sediment of the hydrological station of Cheng County is 133,600 t, the average total sediment load of many years is 1.024 million t, and the average sediment load modulus of many years is 682 t/km2. According to the calculation, the average suspended load sediment of many years of Moba gorge dam is about 147,200 t, the annual bedload sediment is about 22,100 t, and the average total sediment load of many years is 169,000 t. After completion of the project, the speed of the water floor is reduced, which is conducive to sediment deposition, and thus sediment deposition speed in the reservoir can be accelerated. In order to ensure the capacity, the project should discharge sediment to the downstream irregularly. In the sediment discharge period, the flow of the diversion effect river section will be increased, the sediment concentration will be increased, but the impact to the downstream river is in the acceptable range. 4.1.2 Impact on Local Climate After running of the reservoir, the original undulating land of the submerged area is replaced by smooth water surface, so that the energy exchange method and intensity between the underlying surface and the air are changed. As the heat capacity of water is more than that of the land soil, the temperatures, before and after constructing the reservoir, of the same point in the submerged are different, the horizontal exchange is caused due to the temperature difference of land and water, and the temperature of the land around the reservoir is also changed. Due to the large-area water storage formed by the construction of the project, the evaporation capacity is increased and the rainfall is increased; due to the effect of lower temperature of the reservoir, the distribution of rainfall is changed, the rainfall of the protected areas over the reservoir and the coastal flow will be reduced, and the rainfall of the windward slope along the air flow direction will be increased; the underlying surface of the reservoir region is changed from a land surface into a water surface, and the energy exchange method and intensity thereof to the air are changed, so that the temperature is changed, the annual mean temperature is increased slightly, but the regional impact is in the acceptable range. 4.1.3 Impact on Water Environment and Mitigation Measures 4.1.3.1 Impact of Construction Period on Water Environment and Mitigation Measures 4.1.3.1.1 Foundation Pit Wastewater Treatment Measures The foundation pit drainage of the project is mainly composed of precipitation, seepage, concrete pouring and maintenance water, and foundation pit excavation drainage; the main pollutant is composed of SS, pH, and oil.

The change of the water temperature will influence the vertical structure of the reservoir, so as to form water temperature stratification, according to the determination based on runoff-storage capacity ratio method, alpha=2.52, the reservoir is a stable layered reservoir; beta=0.2, and the impact of flood to the water temperature structure is basically free. 4.1.3.2.2 Impact on Water Quality and Mitigation Measures According to the survey, the upstream of the reservoir has a lead-zinc concentrator, a gold concentrator and a gold ore mine. The two concentrators has been closed by the Environmental Protection Bureau of Cheng County, and the gold ore mine will be closed down soon. In addition, the ambitus of the reservoir does not have pollution and industrial pollution enterprises, when the concentrators and the gold ore mine are closed, the impact on the water quality of the reservoir is mainly caused by regional soil and water loss and the organic matters of part soil are entered into the reservoir together with the sediment, so that the sediment in the reservoir is increased, and the contents of nitrogen and phosphorus are increased. However, the generation is relatively small, and the water quality of the reservoir will not be impacted basically; in order to ensure the water quality of the reservoir, the following measures should be taken when the project is completed, so as to prevent the impact of unexpected incidents on the water quality: (1) Strengthen water quality monitoring the reservoir area, complete the cleaning work well, and regularly fish the floating material on the water surface of the reservoir. (2) Draw a certain range with clear boundary as the water source protection area on the upper and lower basins of the water intake port and the deep land-based area, protect strictly, take practical and effective measures, and prevent water pollution. (3) In order to ensure standard discharge of the water source, the ―Moba gorge water source protection regulations‖ must be developed according to the relevant laws and regulations of the Country and Longnan City, so as to protect the water source effectively. (4) Strengthen natural vegetation protection and ecological construction, prohibit deforestation, protect natural vegetation and water source conservation, and reduce water loss and soil erosion. 4.1.3.2.3 Water Source Protection Measures (1) When the ―Moba gorge water supply project is completed, the water source engineering construction management department of Moba gorge for city water supply of Cheng County should divide a drinking water source protection area according to the requirements of ―Pollution Control Management Regulations of Drinking Water Source Protection Area‖ and manage by complying with the regulations completely. ① First-grade Protection Area Prohibit new construction and extension of the construction projects which are not related to the water supply facilities and water sources protection, prohibit the discharge to the basin, and remove the discharge port; Prohibit the wharf which is not related to the water supply requirements, and prohibit vessel callings; Prohibit the industrial waste, municipal waste, manure and other wastes from stacking and storing; Prohibit the construction of oil depot; Prohibit from engaging in cultivation and livestock restocking, and strictly control cage culture activities; Prohibit the tourist activities and other activities which may pollute the water source. ② Second-grade Protection Area Prohibit new construction and extension of the construction projects for discharging pollutant to the water. The discharge of pollutant in the reconstruction project must be reduced, the wastewater discharge of the original discharge port must be reduced, and the water quality in the protection area must be in line with the water quality standards provided; Prohibit the construction of the wharf for loading/unloading garbage, manure, oil and toxic substances. ③ Quasi-protection Area Wastewater directly or indirectly discharged to the basin must be in line with the national and regional wastewater discharge standards. When the total discharge amount of the protection area cannot be in line with the standards provided, the discharge load must be reduced. (2) The water source engineering construction management department of Moba gorge for city water supply of Cheng County should compile an ―Environment Protection Plan of Drinking Water Source of Cheng County‖ according to the ―Compilation Technical Specifications of the ‘Environment Protection Plan of National Drinking Water Source‘‖ (May 2006). (3) Strengthen the construction of water conservation area. In the protection area of Moba gorge water source, the vegetation construction should be strengthened, the forestation should be strengthened, the damage to the vegetation cover should be reduced, the forest coverage should be improved, and the ecological water source should be protected. (4) Strengthen the use management of farmland pesticide and fertilizer in the protection area. As the upstream of the Moba gorge water source has part of plantation, the large-scale use of pesticide and fertilizer will be entered into the surface water bodies together with the rainwater, so that the ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in the water quality of water source are obviously exceeded the standards, which not only affect the water quality of the reservoir, but also affect people's health directly. Thus, the use of pesticide and fertilizer must be strengthened, and the agricultural non-point pollution should be reduced. (5) Order to close the two concentrators upstream the reservoir, and close the gold ore mine, treat the remaining issues, and develop perfect emergency plan. (6) Strengthen water quality monitoring of water source 4.1.3.2.4 Impact for Domestic Wastewater of Management Station and Mitigation Measures The wastewater discharged in the operation period mainly comprises the domestic wastewater of managerial personnel of the management station, wherein the fixed staff of the management station is 35 people, the maximum water consumption of the production and living area is about 3.5 m3/d on the basis of 100L/person/d. Accordingly, the domestic wastewater discharge is about 3.3 m3/d. In order to ensure that the pollution of the water source caused by the domestic wastewater generated by the managerial personnel of the management station is prevented from is prevented, the WSZ buried wastewater treatment equipment is recommended to treat the domestic wastewater generated by the managerial personnel, wherein the specific process is shown in Figure 4.1-4. After treating by the equipment, the discharge concentrations of CODcr, BOD5 and SS are 60 mg/L, 30 mg/L and 60 mg/L, respectively; so that the first-grade standard in the ―Integrated Wastewater Discharge Standard" (GB8978-1996) can be met, the domestic wastewater treated is used as the surrounding green water, and the sludge settled is used as agricultural fertilizer. See the Table 4.1-2 for the effects of WSZ buried wastewater treatment equipment.

In order to reduce the impact of dust on the environment and the construction workers, the following mitigation measures should be taken: (1) In the construction process, the construction site will be provided with blocks and envelope to reduce dust diffusion, the block and envelope play a significant role in reducing the pollution of the dust to the environment; when the wind speed is 2.5 m/s, the impact distance can be shortened by 40%. The surrounding space of the construction site is continuously equipped with the blocks of less than 2.5 m, and the blocks are firm and beautiful; (2) Assign the staff to water the construction site regularly to reduce dust emission on the construction site, wherein the time of watering is determined according to the weather, wherein the general frequency is 1 to 2 times per day, and the time can be appropriately increased in case of high wind or dry weather. The impact of watering operation on the construction site is large to the dust; after watering the dust can be reduced by 28 to 75%, and therefore the impact of the dust on the environment is reduced greatly; (3) Set a tarpaulin on the vehicle for transporting the building materials and the construction waste to reduce scatter. At the same time, the tires of the vehicle should be cleaned with water while accessing the site and loading and unloading on the site, and the traffic route of the vehicle should be prevented from the residential areas as much as possible. (4) In the application of commercial concrete, the construction work of windy weather should be prevented as much as possible. At present, it is determined that the earthwork and stonework construction is prohibited in wind of Category 4, the project can learn from the provision; (5) Assign a specially-assigned person who is specifically in charge of the treatment, cleaning and stacking of spoil, construction waste and building material on the construction site, wherein the stacking yard should be provided with a cloth cover or watered to prevent secondary dust; (6) The construction waste and spoil should be treated and cleaned in time, so as to reduce the space, prevent dust pollution, and improve the environment of construction site; (7) In the mechanical excavation process in the tunnel, the intermittent operation method is used, the ventilation should be in time, and the construction worker should wear a mask, if necessary. 4.1.4.2 Exhaust Gas Environmental Impact and Mitigation Measures In the construction process, the fuel exhaust gas generated by the construction machinery and the transport vehicles mainly comprises CO, NOx and THC. The total amount of the fuel consumed by the project is 1663.4 t, and the discharge of each pollutant is as follows: CO is 148.1 t, NOx is 95.78 t and THC is 27.5 t; the tail gas discharge port of the fuel machine is low, and the discharge belongs to low-point source disorder discharge, and the discharge mainly in the range of 100 m in relation to the discharge source. In the project, the environmental sensitive points in the range of 100 m in relation to the construction area are free, and the discharge mainly impacts the construction area. The impact of the transport vehicles on the environment along the route in the transportation process is relatively small. In order to mitigate the impact of exhaust gas on the environment, the management of large-scale fuel construction machinery and vehicles should be strengthened, the regular inspection and maintenance system should be implemented, and all the tail gas discharge of fuel machinery and vehicles of the contractor should implemented according to the ―Automobile Air Pollutants Discharge Standards‖, and the smoke and dust removal equipment must be provided in case of the purpose of standard discharge cannot be achieved. The construction machinery uses unleaded gasoline and other high-quality fuels. Strictly implement ―In-use Vehicle Rejection Standards‖, implement a mandatory retirement and update system, and update the old vehicle with more engine fuel consumption, low efficiency and seriously excessive exhaust gas discharge. 4.1.5 Impact on Acoustic Environment and Mitigation Measures The noise impact of the project is mainly presented in the construction period, the noise impact of the operation period on the environment is relatively small, so that the impact on acoustic environment and mitigation measures are mainly targeted to the construction period. The construction machinery used in the project mainly comprises rock drilling machines, bulldozers, excavators, mixers and drills and etc., and the noise source will have some impact on the surrounding acoustic environment without taking measures. The acoustic pressure level is shown in Table 4.1-3, and the prediction results are shown in Table 4.1-4.

But in the actual construction process, variety of machines are always used simultaneously, the noise impact will be greater than the scope; (2) In the range with the distance about 5-35 m to the construction site boundary, the impact of construction noise on the surrounding acoustic environment is relatively large; (3) With the completion of the project, the construction noise will no longer exist, so that the adverse impact of construction noise on the environment is temporary and short-term. In order to mitigate the impact of noise in the construction period, the following mitigation measures should be taken: (1) Control from the acoustic source: construction units should require the main mechanical equipment used by the construction unit is low-noise mechanical equipment while signing the contract with the construction unit, meanwhile, the construction unit should appoint a specially-assigned person to regularly maintain and service the equipment in the construction process, and the construction unit should be responsible for training the on-site staff so as to use the various machines by complying with the operation specifications strictly. Reasonably arrange the service time of hammers, air hammers and rock drill machine and other high-noise construction machinery, reasonably arrange blasting time, and reduce the noise generated by the equipment in the abnormal operation process. As the distance of Majiaya construction site to the Majiaya is 400 mm, the distance of Xiaozhuang construction site to the Xiaozhuang is 650 m, the nighttime construction will have a greater impact on them, so that the high-noise construction machinery (such as rock drilling machine and drill) should be prohibited from night construction. (2) In the structure stage of construction, the exterior of the building should be equipped with a block, so as to reduce the impact of equipment noise on the surrounding environment. (3) Personal protective measures of construction workers: strengthen labor protection, and improve workers' working conditions. For the construction workers in the high-noise environment of the first production line, the consecutive working hours per day should not be more than 6 h; the construction workers with large noise impact should be provided with noise protective equipment; and the workers on the construction site should wear anti-noise cotton to reduce the impact of noise. 4.1.6 Impact of Solid Waste on Environment and Mitigation Measures Thereof 4.1.6.1 Impact of Solid Waste of Construction Period on Environment and Mitigation Measures Thereof 4.1.6.1.1 Impact of Construction Waste and Vegetation Cleaning on Environment and Mitigation Measures Reference to the ―Technical Specification for Cleaning Solid Waste on the Bottom of Three Gorges Reservoir" and the requirement of water source protection, the vegetation and the construction waste of submerged area in the project should be cleaned. According to the estimation, the vegetation to be cleaned is about 50,000 m3, and the construction waste cleaned is about 14.13 t. The part of the vegetation cleaned further can be restored, and the optional stacking of the vegetation not only has impact on the environment, but also wastes resources. The vegetation which can be restored is recommended to be given the farmers of the surrounding villages, and the vegetation which cannot be restored is transported to the landfill site of Cheng County. The construction waste cleaned is transported to the residues place of the project. 4.1.6.1.2 Impact of Household Wastes of Construction Workers on Environment and Mitigation Measures As the huge quantities of the project, the construction workers are more, the random storage of a lot of household wastes not only pollute the environment, but also easy to breed mosquitoes, which is harmful to human health. In order to mitigate the environmental impact of household wastes, each construction site should be equipped with two garbage cans, and the total number of the garbage can in the construction site is 28. The household wastes are uniformly stored in a sealed garbage can, regularly collected by a special car and subsequently transported to the landfill site of Cheng County to landfill. 4.1.6.2 Impact of Solid Waste of Operation Period on Environment and Mitigation Measures When the project is completed, the total establishment determined of the operation management personnel is 35 people. The household waste generated by each person per day is 0.8 kg, and the household waste generated by the 35 people per year is 10.22 t. In order to prevent the impact of household waste on the surrounding environment, the management station is provided with 2 garbage cans to collect that, and the household waste will be regularly transported to the landfill site of Cheng County to implement centralized treatment. 4.1.7 Impact of Environmental Geology and Mitigation Measures The dam area of Moba gorge water source project and the neighborhoods belong to east-west Qinling tectonic system and the composite part on the east of the Wudu epsilon structural system, the project is located in the northwest edge of the emblem basin. Both the north and south sides are composed of a series of curved folds and fractures of SWW ~ NEE direction. In the early Quaternary Pleistocene, the area also belongs to the general uplift phase of Qinghai-Tibet Plateau due to the impact of movement of the Himalaya, and accretion of 10 to 50 m thick of the Quaternary system is accumulated in the area. In the project area, the movement of the new construction is relatively active, and the movement mainly comprises differential uplift and subsidence, the movement is more prominent in the Quaternary; the valley terrace is developed, and the more active fractures are developed in the periphery of the project area. In the range of the project area, the active fracture is free, and the construction site is in a relatively stable tectonic area. The acceleration of peak ground motion of the construction site is 0.20 g, the basic earthquake intensity is VIII degree, and the ground motion response spectrum characteristic period is 0.40s. The distance of the latest active fracture to the dam is 6 km. In order to mitigate the impact of environmental geological disasters on the project, the purpose of protecting geological environment and preventing and reducing the loss of geological disasters should be achieved according to the principle of "prevention first, combining prevention with control", and the following recommendations of control measures are provided for the various types of geological disasters: (1) For the collapse of fat rock and soil and caving and other geological disasters which may be presented while excavating the abutment construction, temporary support or temporary bracing and other measures can be taken to ensure the security and stability of abutment construction, and the surface and groundwater discharge work should be simultaneously completed well. (2) For the collapse and caving-in and other geological disasters of slope break and weathered sediment layer which may be presented while excavating the inlet of the water tunnel, the outlet slope and the construction, temporary support or temporary bracing and other measures can be taken while combining with the permanent slope protection measures of the hole face slope, so as to ensure the security and stability of construction and operation, and the discharge and guide work of surface and groundwater should be simultaneously completed well. (3) When the tunnel through the broken belt or soft interlayer, the stability of surrounding rock is poor, the collapse, roof collapse and other geological disasters may be caused, the support should be provided in time while excavating, the support should be provided while excavating, and the waterproofing work of the tunnel should be made well. (4) For the lateral sliding of foundation pit geotechnical slope and collapse and other geological disasters which may be presented in the excavation process of dam foundation, temporary support or temporary bracing and other measures can be taken, the high slope formed after excavation should be shown in the form of cascade slope, so as to ensure the safety of the foundation pit slope in the construction period. (5) The earthwork and stonework construction should be subjected to the operating for filling with the excavation as far as possible, so that the unstable slope caused by stacking the residues can be reduced, the residues must be stacked should be provided with corresponding protective measures. 4.1.8 Impact on Ecological Environment and Mitigation Measures 4.1.8.1 Impact on Terrestrial Animals and Mitigation Measures 4.1.8.1.1 Impact of Construction Period on Terrestrial Animals and Mitigation Measures (1) Impact on mammals The interference of construction activities of the project to the mammals mainly in the hub, plant and tunnel construction areas, the impact on the mammals mainly comprises the drive of construction activities and construction noise to the mammals, namely the animals fled to other places after frightening, and the food debris and wastes left behind by human activity will attract rodents (mice) gather in the construction area. As mammals will avoid the harm caused by the project construction by means of migration, the total direct impact of the project construction to the mammals is small. With the completion of the construction activities and the restoration of the construction site and the nearby natural ecological environment, the animals will return to the original project area, so that the long-term impact of the project on the mammals is small. (2) Impact on birds The construction activities will cause disturbance and destruction in the habitat of the bird, so that the habitat of the bird will be directly or indirectly destroyed, the nests will be damaged, and the bird habitat in the shrub niche will be disturbed. Due to theses impacts, most of the birds will migrate to other places far from the construction site, and a small part of the bird with shrubs and forest-dwelling habitat will disappear from the project area due to the loss of the habitat; a part of the bird populations will be reduced as the nest destruction, particularly the construction period is in the bird breeding season (summer). The overall result is that the species and number of the bird in the project range are reduced. Since most birds will fly and make a short-distance migration to avoid the harm caused by the construction project, the impact of the project construction on the bird is small. The main indirection impact is the reduction of the foods such as rodents of the birds in the project area caused by the construction interference, thereby forcing the birds to prey in a greater range. With the completion of the construction activities and the restoration of the line construction site and the nearby natural ecological environment, the birds in the project area will return to the project area, so that the long-term of the project on the birds is small. In order to ease the impact of construction period on the terrestrial organisms, the education of ecological protection to the construction workers should be strengthened by means of notice, dissemination of brochures and other methods in the construction period of the project, the construction workers are strictly prevented from cutting the trees, outside the construction site, without permission by means of institutionalization, and the construction workers are prohibited from preying frogs, birds and snakes and other wild animals. The Majiaya Qiaotou construction site of the left bank, the construction site upstream the dam of left bank, the Xiaozhuang-Gumugou construction site of right bank, the dam construction site between the cofferdams, the construction site upstream the dam of right bank and water pipeline construction site and other sites are provided with 1 to 2 blocks of terrestrial vegetation and wildlife protection warning signs, and the total number of the warning sign is 15 blocks. The warning signs are thin steel plates with blue bottom and white words, the specification of the warning sign is 100 cm x 60 cm, (length x width), and the warning sign has the words of prohibiting vegetation destruction and wildlife hunting. The operation mode and time of the construction machinery should be reasonably arrange, the construction mechanical equipment should be the mechanical equipment with low acoustic level, and the time of whistle of the transport vehicle should be reduced, so as to reduce the disturbance of construction noise to the wildlife. 4.1.8.1.2 Impact of Operation Period on Terrestrial Animals and Mitigation Measures When the project is completed, the impact of the project on the local animals will not be significant while ensuring the discharge ecological water use. The habitat of the wildlife at the reservoir area will not be reduced as the water storage of the project, and the project will impact some species of the reservoir area; however, the impact is short, and the new habitat environment can be formed after a period of time, so that the impact of the project on the local wildlife is in an acceptable range. The damage of variety of vegetation and habitat types caused by the construction should be gradually restored by implementing ecological restoration measures in the operation period, and the wildlife habitat can be partially restored. 4.1.8.2 Impact on Aquatic Life and Mitigation Measures According to the ―Aquatic Life Status Monitoring of Environmental Impact Assessment of Cheng County Moba Gorge Water Source Engineering of Gansu Province and Apecial Report of Assessment‖ provided by the Fengyuan ecological counseling center of Gansu, the following analysis is provided: (1) Impact on fish and mitigation measures The construction of the project will change the position for the spawning ground and the wintering ground of Schizothorax subfamily in a short time, but due to the Schizothorax fish will soon find a new wintering ground and spawning ground as the same habitat upstream, so that the wintering and spawning process can be carried out. When the new wintering ground and spawning ground are found, the impact of the project is free. Thus, the impact of the project on the wintering and spawning of the Schizothorax fish is free while ensuring the discharge water. In order to mitigate the impact of the project on aquatic life, following measures should be taken: ① The most basic discharge flow for the growth, reproduction, habitat and wintering and other survival conditions of the aquatic life (especially fish) must be ensured, particularly the discharge should be increased in fish breeding and wintering season. ② Effectively implement the spirit of ―Chinese Aquatic Resource Conservation Platform for Action‖, implement the aquatic organisms maintenance system of "who develops protection, who benefits compensation, who damages restoration", and ensure the on-time and in-full funds for the various funds of aquatic life resources, particularly for the germplasm resources communication and aquatic biological monitoring. ③ The owners should increase the propaganda of the relevant laws and regulations for the protection of aquatic organisms, strictly crack down the illegal practices of poison fishing, electric fish, catch fish and excessive catch by coordinating the local fishery agencies, and resolutely implement the spirit for the notice of natural waters banned of Gansu Province, so as to ensure sustainable development of fish resources, and long-term use purpose. ④ Purchase Jialing Schizopygopsis Tajiri Schizothorax fish artificially bred to implement discharge proliferation. When the water project is finished and run, the discharge cycle is three years, the amount thereof is 2000 Jialing Schizopygopsis Tajiri Schizothorax fishes with the size of 3 to 4 cm, the discharge is a long-term work, and the discharge fees are included in the operation costs. (2) Impact on plankton After the completion of the dam, a reservoir of water is formed, and lots of land and vegetation are flooded; due to the nutrient leached from the flooded soil, the organic matter provided by the decomposition of flooded plants and the scouring effect of the runoff to the surface, a number of nutrients are provided for the growth of algae. At the same time, the growth of algae is convenient as the speed of water flow is reduced, the transparency is improved, and the algal blooms can be promoted. However, when phytoplankton blooms, the transparency of the water is reduced, the optical radiation condition of the water is changed, and the phytoplankton in the reservoir is stabilized after a period of time, so as to reach to a new dynamic equilibrium of algae number. The zooplankton of the reservoir mainly comprises rotifers, cladocerans and copepods. The existing volume and production level of the zooplankton are the impact on the existing volume and production capacity of algae, bacteria and other microorganisms, and the zooplankton is another biological resource in the water reservoir. The change for the geographical position, climate, water temperature and water level of the reservoir are closely related to the reproduction of the zooplankton. (3) Impact on zoobenthos The initial stage when the project is completed, the sediment is deposited on the upstream of the dam, the water surface is expanded, the types of zooplankton, the number of individuals and biomass are increased and improved, a good growing environment and food source are provided to the zoobenthos, so that the biomass and the density of the zoobenthos will be increased, and a rich food source is provided for many indigenous fishes; but as time goes on, the silt layer is thickened, the living environment of the zoobenthos is damaged, and there are some negative impacts on the growth and reproduction of the zoobenthos. If the normal ecological discharge downstream the dam is ensured, the adverse impacts to the zoobenthos are basically free. 4.1.8.3 Impact on Terrestrial Plant In the permanent land of the project, the occupation land of forest is 57.91 hm2 and the occupation land of cultivation is 15.33 hm2; according to the statistics of Cheng County, the local annual production of forest land per hectare is 3200 kg, the annual output of arable land per hectare is 2746.83 kg, the loss of the project to the local biomass is 234.37 t/a, and the details are shown in Table 4.1-5.

As the crowd is complex, the lifestyle is different, the physical conditions are different, the immunity is different, the kinds of pathogen carriers are possible, the susceptibility is enhanced, and a variety of diseases transmission method are coexistent. Thus, if the health protection work cannot be completed well, the infectious diseases can be lead (gastrointestinal, respiratory, and insect-borne), the cross-infection and epidemic spread are easy to be caused, the adverse impact on human health will be caused, so that the health protection work should be paid enough attention. In order to mitigate the impact of construction period on the construction workers, and the following measures should be taken: (1) Hygienic cleaning of construction living area and management area When the civil engineering works of the temporary construction living area and the management area are completed, the site should be cleaned. The garbage, human and animal feces and other contaminants in the site should be cleaned; the sewage pit and the refuse dump should be filled after sterilizing with lime, and the weeds should be cleaned up. (2) Drinking water source protection and drinking water disinfection The drinking water is purified and disinfected, wherein the specific methods are as follows: adding bleaching powder into the drinking water to disinfect after depositing and filtering, adding chlorine into the water for 30 min, so that the killing effect to the variety of intestinal infectious disease pathogens in the water is sufficient when the residual chlorine in the water is more than 0.3 mg/l, and the water purified can be used as drinking water. As the construction and living water is taken from the river and the water source is open, the water quality is easy to be impacted by the human actives around the construction site, so that the protection of the water source should be strengthened, and the protection measures are as follows: the range which is apart from the water source with 100 m should not be provided with temporary life area, management area and production area, and the latrines and seepage pits should be built in the range, and the garbage and other pollutants should not be stacked in the site. (3) Innocent treatment of garbage, manure and wastewater With the collection and treatment facilities arranged on the living area, management area and production area and applied to domestic wastewater, production wastewater and household waste and the like, the innocent treatment purposes of garbage, manure and wastewater are basically carried out. (4) Mosquito prevention, fly disinfestation and rodent control When the construction workers are entered into the site, a good breeding ground will be provided to a variety of animals and insects in case of poor sanitation, the density of mosquitoes and rodents and the like will be improved, and the opportunity of infectious diseases will be increased. Thus, the living area should be subjected into mosquito prevention, fly disinfestation and rodent control, the rodent prevention drugs should be provided regularly so as to cut off the disease source the transmission method. (5) Prevention and quarantine of population health Before entering into the construction site, all the dining room staff of the construction site should be quarantine, part of the construction worker should be subjected to prevention and quarantine by means of a sampling method, wherein the sampling ratio thereof is 15% of the construction workers. Through quarantine, the health status of the construction population can be controlled, and the occurrence of contagious disease in which the construction worker is the epidemic focus can be completely eradicated in time. (6) Crowd evacuation of blasting site The use of explosive on the blasting site is operated by a specially-assigned person, the places around the blasting site are provided with striped flags so as to define the risk area, and all the personnel in the blasting area should be evacuated, so that the casualties caused by blasting can be prevented. 4.1.10.2 Impact of Operation Period on Human Health As the river valley of the project is mainly shown in the form of a "U"-shaped valley, the mountains of the two banks are relatively symmetric, the river is deep, the bedrock of the riverbed is exposed, the falling head is large, and the submerged area does not have large-scale unleveled low-lying land and pond marshy with aquatic weeds and etc., and therefore the submergence for the operation period of the project will not cause the transfer of mosquitoes and the transmission of pathogenesis. 4.1.11 Impact on Reservoir Resettlement and Mitigation Measures The backwater length for the reservoir of the project is 3.5 km, the area of the submerged land is 53.85 km2, wherein in the land, the forest is 45.13 km2, the plantation is 7.45 km2 and the unused land is 1.27 hm2. The submerged area of the reservoir mainly comprises three towns, i.e. Shaba Town, Paosha Town and Chenyuan Town, part area of 6 administrative villages, and the total immigrants thereof is 3 families. In allusion to the special resettlement and compensation problems, the Water Authority of Cheng County develops ―Resettlement Plan of Water Source Project of Cheng County‖, the resettlement point is located in Baimashi Village of Chenyuan Town of Cheng County, wherein the distance of the village to the county is 6 km, the village comprises 8 cooperations, the existing residents is 391, the population is 1,600, the acreage under cultivation of the total village is 2800 Mu, and the net per capita income is 2200 Yuan/year. The distance of the village to the nearest road is about 0.5 km, so that the traffic is convenient. The distance to the post office, shops, schools, kindergartens, theaters and other places is about 1 km. The agricultural products produced therein mainly comprise wheat, corn, soybeans, canola and tobacco and etc. The settlement point planned comprises 20 rooms reconstructed from original farm buildings, the land area thereof is 13.5 Mu, the settlement point has a campus testing field of 76 Mu, wherein the irrigation project thereof is the Lugou reservoir water-saving irrigation project which has been implemented, the requirements of three families to the relocated of Chenyuan Town and Shaba Town can be met, and the irrigable land per capita ensured is about 2 Mu. The compensation measures for the resettlement are in line with the principle of ―ensuring the ‗feasible moving, stable settling, and feasible enriching‘ of the migrants‖, and the compensation measures are reasonable and feasible; the resettlement point has adequate houses for the live of the immigrants, sufficient arable land and good irrigation conditions to ensure the living and production need of the immigrants; the resettlement point has relatively complete municipal facilities, convenient transportation, and favorable new life of the migrants, and the resettlement point can meet the requirements of the resettlement compensation plan. 4.1.12 Dam Break Risk and Mitigation Measures 4.1.12.1 Dam Break Risk According to the research results for the dam safety at home and abroad, the reason for causing the dam break and the break is more and complex, and the reason comprises natural factors and human factors and their mutual relations and complex effects. With the probably analysis, the main reason comprises: (1) Violent earthquake Small earthquakes are not likely to cause the damage and break of the reservoir dam, but a strong earthquake (magnitude is not less than 7.0) is more likely to cause the damage and break of the reservoir dam. As the earthcrust of the place where the reservoir dam is located is relatively stable, the basic seismic intensity is grade VIII, the earthquake fortification of the reservoir dam project is implemented according to the same; furthermore, the reservoir is small (the height of the dam is less than 100), and the earthquake cannot be induced easily, so that the possibility for the large-scale and high-intensity damage of the reservoir dam caused by the earthquake is very unlikely. (2) Temperature change The local damage accident for the concrete arch dam of the reservoir dam due to the temperature change is relatively common, the reason thereof is the thickness of the arch dam is relatively thin, and the arch dam is a highly indeterminate space structure limited by the boundaries. In the operation period of the reservoir dam, the change of the ambient temperature is easy in causing temperature stress in the arch dam body, and the reservoir dam will be broken as the overstressing in certain conditions. However, the temperature change just can cause the local damage of the reservoir dam under normal circumstances, and the suddenly break of the dam can be prevented. (3) Landslides Large-scale instability and high-potential fast slope body will cause enormous swell, the flood downstream the reservoir dam and around the reservoir will be caused, and safety of the reservoir is endangered. Particularly, the large-scale landslides in the place close to the dam and the two sides upstream and downstream are easy to cause reservoir damage and break. Although the project has small-scale hidden danger of slope instability, the total geological conditions of the reservoir area, the dam and the site engineering are relatively good as the diastrophic activity of the place where the project is located are relatively stable, so that the possibility for causing huge surge flood and collapse due to the large-scale instability of the bank and the high-potential landslide is very unlikely. Here, it must be emphasized that the many small-scale instable geologic bodies presented in the slops on the two sides of the river section inside and outside the reservoir area should be strengthened, prevented and subjected to the treatment of embankment and supporting project, so as to prevent the large-scale reservoir banks instability caused by the small-scale reservoir instability can be prevented. In addition, the operation period for putting into production of the reservoir dam, the stone blasting and fish blasting and other blasting activities in the place close to the dam and around the dam should be prevented, and the a large number of materials optionally stacked on the slops of two banks on the place of the reservoir area and the place close to the river downstream the dam should be prevented, and the buildings on the places should be prevented to avoid slump. (4) Destruction of dam foundation The deformation, permeability and stability of the dam foundation are tightly related to the safety of the dam. The good dam foundation should have sufficient deformation resistance and bearing capacity, small permeability and complete and stable rock, so as to prevent the foundation damage caused by excessive deformation, the excessive uplift pressure and the unstable dam body or dam seat rock slide caused by excessive penetration water pressure. The dam foundation of the project can be prevented from the collapse accident caused by instability and deformation, cracking, sliding and water seepage just be strengthening and stabilizing to eliminate the hidden troubles completely through a scientific project processing technology and strict consolidation prevention measures, (6) War and terrorist attacks If the reservoir dam of the project is damaged instantaneously in case of war and terrorist attacks, the flood damage is severe, and the basin-wide disaster may be caused. However, from the military point of view, the possibility for taking the dam as a military target is very unlikely. (7) Extraordinary flood In case of extraordinary flood, the extraordinary flood is always accompanied by heavy rain. Due to the strong erosion effect of the heavy rain, the downstream dam surface will have scour holes. Although these local scour holes will not affect the stability of the dam, the opportunities of overflowing the top of the dam is increased while pushing by the winds and waves in the reservoir. Theses small scour holes will be rapidly expanded under the erosion effect of the flood padding through the dam. When the scour holes are reaches a certain size, the dam will be local instable, and then the dam break phenomenon can be presented. The engineering grade of the reservoir is grade III, the permanent main buildings are designed according to the grade 3, the permanent secondary buildings are designed according to the grade 4, and the temporary buildings are designed according to the grade 5. The concrete gravity dam is designed according to the flood per 50 years and is reviewed according the floor per 500 years, the energy dissipation and erosion prevention buildings are designed according to the flood per 30 years, and these buildings are in line with the requirements of ―Standard for Flood Control‖ (GB50201-94), so that the dam break risk caused by the extraordinary flood can be reduced effectively. (8) Error of survey design If the early work do not be completed well, the hydrographic survey and the geological survey are not detailed, the calculation of the water account is incorrect and the design consider is not thoughtful, the construction may be blind, the hidden danger for the safety of the reservoir will be caused, and the collapse accident of the reservoir is easy to be occurred. Thus, for the flood prevention safety of the dam, the correct survey design and reasonable dispatch application should be paid attention in addition to the reasonable selection of flood prevention standard. The project has done a lot of preliminary works, so that a scientific basis is provided to ensure the quality of design. (9) Quality defects of the dam During the construction process of the dam, the chance of quality defect is always existed due to the uncritical local quality control. The weak link is the place for the occurrence of concentrated seepage and piping, and the dam break can be occurred under the effect of adverse external dynamic loads. Thus, project supervision in the project should be strengthened, the supervision, inspection, evaluation and acceptance of the construction should be organized, and the left tail works should be completed well. (10) Mismanagement of operation In the management work of the dam, the probability of man-made omission and equipment failure is always existed, so that the real-time monitoring for the operation status of the dam will be influenced, the working status of the dam cannot be reflected in time, so that the dam will be dangerous and broken. Therefore, the technical management work of the reservoir should be strengthened, and the safety of the dam should be ensured. In summary, the main reason of dam break comprises low flood control standard of the reservoir, poor construction quality, poor management work and other human factors. But the safety of the reservoir dam can be ensured and the purpose of promoting benefit and abolishing harm can be achieved by seriously implementing the Decree [1991] No.77 ―Reservoir Dam Safety Management Regulations‖ of the State Council, carefully implementing survey design while strictly complying with the regulations, strengthening project quality and technical management work of the reservoir and complying with the provisions for the safe operation of the reservoir. 4.1.12.2 Risk and Result of Dam Break Once the dam is broken, the impacts on the upstream and downstream of the dam are large. In the upstream of the dam, the water of the reservoir area, particularly the water level before the dam will be sharply reduced due to the suddenly discharge, so that the bank of the reservoir dam is easy to be unstable, and the bank is easy to be collapsed. The dam break risk is mainly presented in the downstream, i.e. the dam break wave will be formed as the suddenly discharge of the water in the reservoir, and the damage to the human and property downstream the dam is serious. Thus, when the maximum flow of the dam broken is reached to the flow path L of the downstream dam according to the source strength of the broken dam, the maximum flow is calculated according to the following formula:

wherein, QLm represents the maximum flow (m3/s) for the controlled section of the broken dam apart from the dam with L (m); Vm represents the largest velocity (m/s) of the river section, the value of that in the assessment is 3.0 m/s; K represents the experience factor. The experience factor of the project is 1.2, and the other parameters are ditto. According to the topography downstream the project and the resident distribution condition, the cross-section of rivers of the eight downstream villages which may be impacted are estimated, wherein the details are shown in Table 4.1-10. List for Estimation of Cross-section of River of Each Village Table 4.1-10 village Local dam distance (m) Area of cross-section of river (m2) Majiaya 800 748.53 Jianjiagou 1600 394.63 Zhuanwancun 3500 186.19 Ganlushi 4500 144.81 Xiaozhuang 1300 471.05 Zhangjiashan 1800 350.78 Luangoumen 3300 197.47 Niujiaya 4300 151.55 According to the estimation results of 4.1-10, the households lived in the low-lying and the place close to the river of the eight villages will be submerged, and some villages will be submerged completely. 4.1.12.3 Management Measures of Dam Break Risk In order to ensure the safety of the dam, achieve the purpose of promoting benefit and abolishing harm, prolong the service life of the dam, play the efficiency fully and avoid the dam collapse disaster and risk, the project should take the various of effective protection measures and emergency measures in the whole process of survey, design, construction and operation, so as to take preventive measures and check erroneous ideas at the outset. According to the environmental risk analysis result of the reservoir dam of the project, the reference to the reservoir dam safety work research results at home and abroad, the following prevention and emergency measures are provided by targeting to the main reason which may cause dam damage and dam break. (1) Seriously implement the ―Reservoir Dam Safety Management Regulations‖ (State Council [1991] Decree No. 77). The Regulations clearly defines and strictly requires the construction, management and treatment of the reservoir dam with the height of more than 15 m or the capacity of more than 1 million m3. (2) Strictly handle affairs according to the hydropower project management procedures. In order to prevent damage and break of the dam, the survey, design, construction, acceptance, operation, identification and reinforcement works should be completed well in order. (3) Strengthen geology investigation work of the project. In the project, the geological conditions of the reservoir area, the dam site, and the plant site are relatively complicated, the detailed geological and groundwater survey work should be carried out, and the situation should be identified successively. (4) Carefully design by strictly complying with the specifications. (5) Enhance quality management of project construction. In order to ensure safe operation of the reservoir, the construction period for the construction of the reservoir dam should be provided with the concept of "long-term project, quality first", the supervision work of the project should be strengthened, the quality supervision, inspection, evaluation and acceptance works of the project should be organized, the specifications of construction technology should be carried out, the construction material should be reasonable, the construction work should be strict, and the left tail work should be treated well, so as to ensure the quality of the project and eliminate ―purple‖ project. (6) Strengthen the technical management of reservoir operation. In order to ensure safe operation of the reservoir, a complete reservoir operation schedule and a safe operation of technical system should be established in the operation period for putting into production of the reservoir dam, the level of technical management should be improved, the flood prevention program and schedule application plan should be compiled reasonably, the provisions for the safe operation of the reservoir should be complied; the safety monitoring and identification works of the dam should be emphasized, the dam protection on the bank of the reservoir and the maintenance of the gate crane should be strengthened, the facilities meeting the dam safety observation are set, the safety condition of the dam should be frequently inspected and regularly observed, the flood data should be rechecked, so as to achieve the purpose for finding the problems in time, taking measures in time and preventing the reservoir from adventure operation; the reliable forecasting of construction, early warning systems, transportation and communication facilities improvement should be paid attention, an emergency flood plan should be developed to achieve the purpose of preparing before the flood and responding while flooring; and the power supply and equipment which meet the requirements of gate starting and closing are set to ensure the timely drain. For the flood caused by extraordinary rainstorm, the extraordinary drain measures should be prepared, and the notice on the flood fighting work should be issued in advance. (7) Prohibit the slump in the reservoir area. In the operation period for putting the reservoir dam into production, the stone blasting and fish blasting and other blasting activities in the place close to the dam and around the dam should be prevented, and the a large number of materials optionally stacked on the slops of two banks on the place of the reservoir area and the place close to the river downstream the dam should be prevented, and the buildings on the places should be prevented to avoid slump. 4.1.12.4 Emergency Plan The emergency plan for the dam break risk of Moba gorge water source engineering is "APELL plan" (Awareness Preparedness for Emergencies at Local Level).
