located in the northwest part of China, and in the middle of Xinjiang Uygur Autonomous Region by east lies Turfan Prefecture, a basin among mountains at the foot of Tianshan Mountain in its south, 300km long from east to west and 240km from south to north, with a total area of 69,713km 2 . Its geographically position is longitude 87°16 -91°55 east and latitude 41°12 -43°40 north. Abounding with land and photothermic resources and teeming with melons and grapes, Turfan Prefecture is one of China’s famous tourist attractions with its unique natural scenery. The climate of Turfan Prefecture is typical of continental warm temperate desert zone, full of sunlight, rich in thermal energy but extremely dry with rare rainfall and frequent winds, hence the name “fire continent” and “wind storehouse”. Its annual average precipitation being 16.6 mm and annual evaporation 2,845 mm, the prefecture is one of the extremely desert areas in China. Water resources are most scarce in the place, amounting to 535 million m 3 in total. The problems with water resources utilization at the present are, on the one hand, water resources are unevenly distributed among the seasons. There are very few control structures in the mountains, so it is impossible to effect spatial regulation of water. As a result, very little surface water can be diverted and utilized during flood period and water is very short during dry season. On the other hand, deep irrigation, series irrigation and other flood irrigation methods are still being adopted in agriculture in the prefecture, which cause unnecessary waste of water. At present, industrial and agricultural development in Turfan Prefecture rely mainly on surface water and groundwater. However, in recent years, with rapid economic development water use in various sectors has been constantly increased. Especially in industries much more water has been used, resulting in sharper and sharper conflict between water supply and demand in the region. In order to meet the normal domestic and production needs, people have started exploiting groundwater in enormous quantities and water table has dramatically declined, causing a series of environmental problems: groundwater overexploitation, Kariz systems dry-up, serious conflict between water resources shortage and rapid development, and degradation of the already very fragile environment. Therefore, water saving in a planned manner and agricultural development through water saving have become the only solution to the agricultural and economic development of Turfan. In order to broaden its financing channels of water saving irrigation in agriculture, speed up its water saving society development and achieve its sustainable development objectives, Turfan Prefecture Water Bureau, Regional NDRC and Regional Finance Department agreed with the World Bank and water bureaus of Turfan City, Shanshan County and Tuoxun County on the plan to use World Bank loan at an amount of $100 million for the water conservation project in the prefecture. The proposed World Bank Financed Turfan Prefecture Water Conservation Project comprises civil works construction and management system and institutional capacity building. The construction component includes: a) constructing three medium- and small- sized mountain reservoirs; 2) reconstructing 47.5km of lined main and branch canals; b) constructing 161.4 thousand mu of water saving irrigation schemes for agriculture; c) for Kariz system preservation, restoring one selected Kariz system to protect ancient water Page 5 3 delivery system of historical cultural heritage. The management system and institutional capacity building part includes: d) carrying out integrated water and environment management by introducing integrated basin management concept and methodology; e) for institutional capacity building, establishing WUAs, monitoring and evaluation system and management information system. For names and area of the subprojects and EIA report (table) preparation institutions, see Table 1.1-1. Subprojects, their area and EIA report (table) preparation institutions Table 1.1-1 City county Serial No. Code Name of subproject EIA preparation institution 1 TLF1 Meiyaogou Reservoir 2 TLF2 Turfan City water saving irrigation 3 TLF3 Tarlang Branch Canal Turfan City (4) 4 TLF4 Wudaolin Kariz system preservation Xinjiang Institute for Water and Hydropower Survey, Design and Research 5 SS1 Ertanggou Reservoir in Shanshan County 6 SS2 Water saving irrigation in Shanshan County Shanshan County (3) 7 SS3 Ertanggou branch canal lining reconstruction Xinjiang Institute for Water and Hydropower Survey, Design and Research 8 TKX1 Alagou Reservoir in Tuoxun County Hunan Institute for Water and Hydropower Survey, Design and Research 9 TKX2 Water saving irrigation in Tuoxun County Tuoxun County (3) 10 TKX3 Alagou main canal Xinjiang Institute for Water and Hydropower Survey, Design and Research Note Since the seven subprojects of TLF4,SS2,SS3,TKX2 and TKX3 have very little environmental impact due to their small scale, small quantity of work and simple construction. In accordance with relevant domestic regulations on EIA and World Bank safeguard policy requirements, only tabulated EIA reports are prepared. The goals of this project are to adopt the new concept and methodology of integrated water and environment management and agricultural water saving irrigation with the focus on non- beneficial evapotranspiration (ET) reduction, improve regional on-farm water infrastructure, attach importance to software development, push forward with sustainable water resources utilization and development, and facilitate socioeconomic development in Turfan Prefecture. The specific objectives of the project are to increase regional flood control capacity so that flood water resources are effectively utilized, increase the number of employed farmer labors, improve canal and irrigation efficiency, reduce non-beneficial ET in the project area, cut down on total ET in the project area, increase agricultural output value in the project area, reduce groundwater drawdown in the project area, protect Kariz system of cultural heritage, and make regional project management in keeping with international practice. 1.2 Objectives of Environmental Management Plan (EMP) The environmental management plan is prepared for the purpose of formulating a set of detailed environmental measures that are technically feasible and financially sustainable and operable in view of the unavoidable potential adverse impacts of the project on environment to specify that the project contractors, supervisors, operators and environmental management department will implement measures and arrangement for environmental mitigation and management and institutional establishment during project implementation and operation so as to minimize as much as possible or compensate for the adverse environmental and social impact of the project and reduce it to an acceptable level. The specific objectives include: Page 6 4 1) Specifying environmental management obligations of the contractors and operators Xinjiang Uygur Autonomous Regional Environmental Protection Department, Turfan Prefecture Environmental Protection Bureau, the environmental impact assessment institution and the design institution have carried out detailed field verification and confirmation with regard to environmental protection objectives and come up with effective environmental impact mitigation measures, which are included in the project design as contractual responsibilities of the project construction contractors and operators. 2) Serving as operational guidelines on environmental management The environmental monitoring plan for construction and operation periods stipulated by the EMP will ensure effective implementation of the environmental impact mitigation measures and will be provided as an environmental protection document to the construction supervisor, environmental supervisor, and other relevant organizations during construction and operation periods to specify the responsibilities and roles of relevant function departments and management organizations and provide for communication channels and methods among various departments. 3) Ensuring funds for environmental management actions In the EMP, costs of environmental management, environmental supervision and capacity building are estimated and their sources are explained to ensure implementation of the various environmental management actions. The management costs include staff salaries, office expenses and transportation costs. The EMP serves to avoid and control adverse environmental impact during project implementation and operation, for which purpose it sets out the environmental impact mitigation measures, monitoring measures and legal and regulatory tools to be implemented and measures for ensuring implementation of these measures. At the same time, it is the key link to connect the assessment of EIA with detailed environmental impact mitigation measures and their alternative measures. For each of the environmental management measures the EMP provides for its technical implementation, investment estimates, implementation plan, government agency functions, funding sources and monitoring plan. In order to achieve the mitigation objectives the measures set out by the EIA and EMP must be fulfilled. 1.3 Preparation of the Environmental Management Plan The EMP of “Turfan Prefecture Water Saving Irrigation Environmental Development Project” comprises the overall EMP and 10 subproject EMPs. The subproject EMPs are prepared by the project owners and their environmental impact assessment institutions with descriptions focused on project budgets and project environmental management plan organization. The overall EMP submitted to the World Bank for review is jointly prepared by Turfan Prefecture Water Bureau PMO and the environmental expert group of Turfan Prefecture Water Bureau PMO. The overall EMP and the subproject EMPs are in consistency and are strictly in accordance with the national level and regional level environmental management regulations. Under the condition of meeting the requirements of Chinese environmental impact assessment, special attention is paid to the requirements of World Bank’s safeguard policies, specifically relevant rules of the operational regulations 4.01. Page 7 5 The information of the overall EMP comes from: 1) Overall EIA 2) Subproject EIAs 3) Subproject EMPs 4) Subproject feasibility study reports 5) Overall feasibility study and assessment report 6) Workshops organized by PMO and attended by subproject environmental impact assessment owners and World Bank representatives 7) Subproject soil and water conservation plan 1.4 Design of EMP The EMP serves as a guiding document for environmental management during project implementation and its action plans mainly include the following three parts: Environmental impact and mitigation measures: main project impacts during its construction and operation and engineering and management measures taken to prevent or mitigate adverse impacts created by the project. Environmental management and supervision plan: environmental supervision actions taken to ensure synchronous implementation of environmental protection measures and project construction. Environmental monitoring plan: environmental monitoring actions taken to supervise the achievement of environmental standards during construction and operation and ensure safe operation and improvement in environmental conditions in the construction areas. Capacity building (i.e. personnel training) plan: knowledge and skills trainings provided for managers, environmental supervisors, full-time or part-time environmental managers and so on during project implementation in order to ensure implementation of the environmental management plan. 1.5 Details of Technical Preparation This EMP is prepared through proper addition, revision and improvement of and based on the “Comprehensive Assessment Report on the World Bank Financed Turfan Prefecture Water Conservation Project, Xinjiang” and the 10 subproject EMPs. As an independent document, it includes all the environmental management actions to be taken during project construction and operation and provides an action guide and framework for the implementation of the adverse impact mitigation measures, environmental supervision, environmental management and environmental monitoring. In addition, the pest management policies of the World Bank under this project are dealt with separately in “Pest Management Plan” and are not concerned in this article.

However, construction of the Ertanggou reservoir will impact to some extend on the native fishes in the Ertanggou river system. Native fishes in the river system include four kinds, namely small eyed loach, small strip loach, Triplophysa stoliczkae and Turpan loach. Therefore, construction of the Ertanggou reservoir will trigger the World Bank safeguard policy of “Natural Habitat”. Mitigation measure: Conducting monitoring of aquatic ecosystem and the fishes in the Ertanggou river system during operation period. 4.1.1.4 Analysis of Environmental Risks and the Mitigation Measures Risks relating to reservoirs’ construction and operation are: transportation and storage of explosives and fuel during construction period; river water pollution during construction period; dam failure during operation period and environmental risks of construction material storage space of the Alagou reservoir and radioactive material distribution, etc. Water saving irrigation sub-projects and new construction/rehabilitation canal sub-projects are typical rural water works in nature. A lot of water works that are similar to the proposed works have been built up in the project area since the past decades. The consequences of those water works and their long-term running prove that those small-size rural water works would not trigger emergent or nonemergent environmental risk basically. Although protection of Karezes is cultural relic restoration project, it will only concern small working quantities and limited area. The consequences of the similar works that have been Page 34 32 done in the project area and their long-term running prove that the protection work works would not trigger emergent or nonemergent environmental risk basically. Hence, this chapter gives analysis on the possible environmental risks to be encountered during construction period and operation period of the proposed project and proposes corresponding mitigation measures and contingency plan. . 4.1.1.4.1 Evaluation on environmental risk of explosive and oil material 1 risk identification The construction and operation of totally 3 (three) reservoirs will not concern with virulent raw material or disproducts; However a certain amount of the explosives and oil material will be needed during construction period. The flammable and explosive material may cause some accidents during their transportation and store or as a result of improper handling. 2 analysis on damages of environmental risk All project concerned explosives and oil material will be transported by road. During transportation, possible traffic accidents would be encountered or occurred, which would lead to oil material leakage, combustion or explosion, then contaminate circumferential bio- environmental and environmental quality or cause environmental damage. In accordance with respective construction scheduling of each reservoir, all transportations necessary for the project constructions will be done by special vehicle, driven and escorted by special professional person so as to effectively get rid of traffic accidents; in addition, transportation capacity of oil material per vehicle shall be strictly controlled in accordance with national codes so that to limit the possible environmental damages probably caused by an accident within a controllable range. (3 preventive measures and mitigation measures Preventive measures against damages that endanger people’s life and property in the process of transportation and store of explosives and oil material during constructions A. Whole transportation shall be in accordance with the rules specified by the Ministry of Public Security of the People’s Republic of China. Before transportation detailed transportation specifications shall be put forward describing transportation line, vehicle, time, escort in transportation, delivery and acceptance, etc. B. The dangerous goods shall be stored in accordance with current applicable rules. It is required that the Contractor should report daily consumption, and then the Supplier should put forward a daily transportation plan, so that those dangerous goods would not be exposed in the project site for a long period. C. The application of those dangerous products shall be in accordance with the applicable codes. Only the persons who received related training, got certificate and are satisfied with security administration requirements are allowed. D. Xinjiang has a very hot summer. The vehicles that do transportation of dangerous goods shall have proper shield against insolation. In addition, appropriate cooling measures shall be taken. E. Strengthen traffic security administration, upgrade technical capability of drivers and give more training on safe driving and courteously driving. Page 35 33 F. In case of a leakage of dangerous goods into river courses during transportation or an accident of pollution of production water or living water with the river water, an water quality monitoring and inspection shall be done at once with concerned region to figure out pollution source diffusion law and incidence, meanwhile, such accident shall be reported to the local government of the downstream area in a timely manner to prevent people from the endangers to their security, health and crops at the downstream area as a result of leakage of flammable and explosive goods, in addition, the administrative department at the upper level shall be reported. G. In then event of an oil leakage of explosion, the people in the vicinity of accident site shall be evacuated immediately. A disastrous fire of the flammable products as a result of leakage caused by people shall be strictly prevented. In addition, given a traffic jam or river course block made by an explosion, vehicles leading and river course unblocking shall be carried out, for instance, the vehicles hold in the traffic jam can be led to other paths. H. After an accident, a professional team shall be assigned to identify the accident nature, assess the consequence, determine the degree of pollution with the water environment and provide decision-making reference for the headquarters and post treatment. I. High dangerous goods, for instance, explosive, shall be taken care of by specific person, handled by specific person and used by specific person. The scope of 100m around the explosive depot shall be set out as dangerous zone with security belt built up. Before utilization of explosives, all people who have no specific job concerned with the explosion construction shall be got out of the explosion scope and kept 100m away, no entrance may be permitted. Preventive measures against the pollution of waste fire -fighting water to the ambient after a fire disaster A. Strengthen training of fire fighting and security on the administrators and improve their fire awareness. B. Bring forward necessary safe production and administration system and provide more safe production training for the administrators. C. Drainage ditches shall be built around perimeter of oil depot. A concrete water tank with a capacity of 1.5 times the maximum waste fire-fighting water shall be built at the end of those drainage ditches to collect all waste fire-fighting water and get rid of arbitrary discharge. 4.1.1.4.2 Evaluation on environmental risk of pollution to river water during construction period 1 risk identification The quality of water in the river reaches where the reservoir project will be located is classified at Class II. In accordance with the integrated wastewater discharge standard, GB8978-1996, no pollution discharge into the river basin may be allowed. Hence, all production waste water and living sewage from the construction of reservoir project will be forbidden to be discharged into the river course and river bed. The construction waste water will be the production waste water and living sewage from construction camp area and construction site. The production waste water will mainly come from machinery cleaning or repairing with the dominant contents of SS and petroleum group. Petroleum group will be heavily harmful to the water quality. Due to the limit of management of construction teams, there would be some treatment of waste water Page 36 34 inconsistent with environmental protection requirements during the construction period, direct discharge of waste water into river course or river bed would occur, river water would therefore risk pollution during construction period. 2 analysis on damages of environmental risk All 3 (three) reservoir proposed are key control reservoirs to be located on Meiyaogou River basin, Ertanggou River basin and Alagou River basin respectively. Meiyaogou Reservoir and Ertanggou Reservoir will be arranged on the middle reaches of respective river basin, but Alagou Reservoir on the upstream reaches. In this case, the water quality situation of downstream irrigation use will be directly subject to the quality of reservoir water after project completion, while, the water function of the river basin where a reservoir will be built will be deteriorated. (3) Preventive measures and mitigation measures put in place various environmental protective measures with regard to the treatment of production waste water and living sewage during construction period. Preventive measures against damages that endanger people’s life and property in the process of transportation and store of explosives and oil material during constructions; Strengthen the training of environmental protection on construction personnel and improve their environmental protection awareness; Aperiodically carry out inspections on the si te. Strictly forbid direct discharge of production waste water and living sewage into river course or river bed; Effectively put in place the water environment monitoring and measurement plan during construction period. 4.1.1.4.3 Risk of dam failure 1 risk of dam failure of proposed reservoirs The types of dams to be a part of the proposed reservoirs are that: concrete-faced rockfill dam for Meiyaogou Reservoir, and concrete-faced rockfill dams both for Ertanggou and Alagou Reservoirs. The statistics conducted by the International Committee on Large Dams (ICOLD) throughout 110 countries and regions with regard to the dams indicate that dam failures indicate that dam failures account for 2.3%, of which earthfill dams take a large percent (earthfill dam failures takes 95% out of all dam failures), while concrete-faced rockfill dam and concrete-faced rockfill dam have a quite low failure rate. The research results both abroad and at home in terms of dam safety show that there are a lot of and complicated factors that would lead to a dam damage and failure finally. The analysis on possible reasons is described as follows: overtopping flood The analysis based on the historic dam failure data shows that most dam failures were caused by overtopping floods. The main reasons leading to overtopping flood are improper design standards, inadequate capacity of discharge facilities or inappropriate dispatching behavior. The Chinese national Standard for Flood Control, (GB50201-94) shall be strictly followed in determining design flood standard because the satisfaction with flood control demands will be crucial to guaranteeing a dam safety. Meiyaogou Reservoir and Ertanggou Reservoir are of class III projects consisting of dams of Grade 3, 50-year-recurrence design flood standard and 1000-year-recurrence check flood standard, so that the discharge capacities are fully consistent with related requirements; Alagou Reservoir is of class III Page 37 35 project consisting of a dam of Grade 2, 100-year-recurrence design flood standard and 2000- year-recurrence check flood standard, so that the discharge capacities are fully consistent with related requirements earthquake Earthquake could deadly damage the rock mass beneath the dam base and ancillaries. The geological reports of three projects indicate that dam area of proposed reservoirs is comparatively stable with less probability of occurrence of earthquakes. Hence, the possibility of earthquake that extensively damage the projects at a large area is at a lower side. Reservoir bank ruin Reservoir bank ruin will lead to a reservoir leakage and reservoir bank instability and endanger dam safety. Thus, the geological reports of three projects indicate that dam area of proposed reservoirs is comparatively stable with less probability of occurrence of earthquakes. Hence, the possibility of earthquake that extensively damage the projects at a large area is at a lower side. dam foundation breakage Dam safety is subject to the deformation, permeability and stability of dam foundation to a quite extent. A fine dam foundation shall have adequate capability to fight against deformation, bear loads, show a low permeability and possess intact rock mass so that dam foundation breakages would not happen, such as large deformation destroying the dam foundation, exceedance of uplift due to over pressure of leakage water or instability of sliding of rock mass that is a part of dam body or dam base. Thus, the geological reports of three projects indicate that the proposed reservoirs would not trigger reservoir immersion and permanent leakage. improper construction and utilization of material Improper behaviors include that poor concrete placement quality due to unstandardized construction workmanship; dam splitting, expansion and erosion due to chemical reactions of alkaline aggregates in concrete; leakage due to poor quality of joint grouting. Those improper construction and utilization of material will degrade dam body, destroy dam body locally and finally threaten dam safety. But those improper people ’s behaviors can be strictly controlled by means of application of codes and specifications. terrorism attack The consequences of the accidents of terrorism attacks are of graveness. However, the possibility of terrorism attacks is quite rare and unforeseen. Generally, the dam failure of proposed reservoir projects is at a quite lower side. 1dam failure of existing reservoirs In accordance with the Dam Safety Policy OP4.37 issued by the World Bank, PMO of Turpan Water Conservation Project (Turpan Water Resources Bureau) entrusted a Dam Safety Expert Panel that is consisting of Nanjing Hydraulic Research Institute and Dam Safety Management Center under the Ministry of Water Resources Bureau of China to conduct an evaluation over the dams of existing reservoirs which the proposed project would be concerned. This Dam Safety Expert Panel has figured out 4 existing reservoirs according Page 38 36 to the WB ’s requirements, including PuTaoGou Reservoir, YaErNaiZi Reservoir in Turpan City, KeKeYa Reservoir in ShanShan County and KanErQi Reservoir in TuoKeXun County, in addition, proposed contingency program. PuTaoGou Reservoir A. risk identification PuTaoGou Reservoir is of a self-filling reservoir without flood control problem, and the stability of main dam and embankment are all satisfied with related code and standard. Hence, Overtopping or dam failure would not occur with PuTaoGou Reservoir. However, in case that PuTaoGou Reservoir suffers a terrorist attack, such as jagging the dam crest, reservoir water may flush through the jag and get the dam failed. The core wall of the main dam of PuTaoGou Reservoir has a bottom of 1m wide. It is specified in the Design of Roller Compacted Embankment, SL274-2001, that earth-made impervious part should have a thickness not less than 1/4 of the water head, so the main dam’s core does not meet stability requirement. Given a damage with the main dam’s geotextile membrane, the core bottom could be destroyed by leakage and finally lead to a dam failure. When multiple frequency floods occur in the Meiyaogou River Basin where the PuTaoGou Reservoir is located, the dam and its downstream reaches would risk in various kinds. The PuTaoGou Reservoir is designed to have a NPL of 125.00m, but its reservoir impoundment plan shows that the highest filling level as so far is 117.25m. In general, the most possible emergency with this reservoir would be as follows: a. Under NPL of 125.00m, main dam’s geotextile membrane is broken, a leakage occurs at El.90.00 of core wall bottom, dam failure happens as a result of dam piping; b. Under present highest NPL of 117.25m, main dam’s geotextile membrane is broken, a leakage occurs at El.90.00 of core wall bottom, dam failure happens as a result of dam piping; c. Under present highest NPL of 117.25m, main dam suffers a terrorist attack, dam crest is jagged, the reservoir water may flush through the jag and get the dam failed; B. analysis on risk damages In the event of a dam failure, both upstream and downstream of the dam would suffer a lot. At the upstream, sudden discharge of a large quantity of water will get reservoir water level drop down sharply, reservoir bank ruin happens, wave surge induced by bank ruin will impact the dam sequentially. However, the most damages would occur at the downstream because sudden discharge of huge amount of water will cause high wave surge and flush out in a manner just like overturning the mountains and upsetting the sea, gravely destroys would be imposed. C. preventive measures and mitigations measures a. establishment of emergency and contingency system Centering Turpan Flood Control Command Centre, Turpan establishes a flood control and emergency institutions at various levels from bottom up, the administrative chief of each level is responsible for his level’s command centre. Turpan’s flood control institutions have Page 39 37 two levels as: Turpan City flood control headquarters and township/national farm flood control command centre. b. emergency headquarters leaders and staff and institutions involved The emergency headquarters is Turpan Flood Control Command Centre, it shall strictly follow the principle of administrative chief taking responsibility. The Mayor who is also the chief commander is assigned to be in charge of whole flood control issue. The vice commanders are the leaders from city committee and government. All staff members of the centre are the leaders from related township, national farms, who shall be the chief of those institutions. Turpan PuTaoGou Reservoir Contingency Program gives a detailed list describing names, positions and institutions of the leaders and members of this emergency command centre. c. emergency inspection patrol Patrol route: PuTaoGou Reservoir —YaErNaiZi Reservoir; Patrol time: from 18 p.m. to 20 p.m. every day (Beijing Time); The name list of possemen consisting of the patrol team is included in the Turpan PuTaoGou Reservoir Contingency Program. d. rescue team Rescue team members must obey orders, follow mission, come at commander’s order and do a good job. Those members shall be given training and mobilization advertising, and they shall an awareness of devoting into a rescue at once in case of an emergency. Such a rescue team consists of the youth and able men from nearby PuTao Township, QiaTeKaLe Township as well as possemen from original weed farm. Once a pre-alarm or emergency arises, such team shall be well mobilized by the Party Secretary or government at township level to conduct rescue. When an emergency is beyond the capacity of township level, the flood control and emergency headquarters at city level shall do all its best to mobilize the human resources from the institutions involved or call for a hand from local army. YaErNaiZi Reservoir A. risk identification The status-quo of the safety situation of this reservoir’s dam, the field inspection result and the dam data pertinent show that the most possible emergencies of this dam would be as follows: a. in the event of a flood over 500-year-recurrence or equal to a 500-year-recurrence check flood of 16.93m, but the gates at the sluice and discharge outlets can be handled normally, meanwhile the emergent spillway can’t ensure a smooth discharge; b. in the event of a reservoir NPL of 15.00m, a piping occurs at downstream dam toe and destroys dam fill; c. in the event of a large-scale mountain collapse (it could block the normal discharge through emergent spillway), then reservoir level may rise up during flood period, and reach dam crest level even exceed dam crest level; d. in the event of multiple-frequency flood occurring in the TaErLang River Basin (YaErNaiZi Gulley) where the reservoir is located, emergencies in some ways happed at the dam and its upstream; e. in the event of failure of the gates at the sluice and discharge outlets, those gates can be handled normally. B. analysis on risk damages In case of a dam failure, the overtopping flood may ruin reservoir management station within 30s, rush out of the YaErNaiZi Gulley after 2 minutes approximately, devour copper Page 40 38 mine plant on the right bank of the gulley entrance (about 0.8km away from the dam), swallow 8 rural household and their irrigation land in YaErBa Township on the left bank of the gulley entrance, after that, run down continuously at a high head along the downstream route of the gulley, overtops a country road after about 15 minutes, flood the ChunGuang Group No.1 totally and its irrigation district of YaEr Township of 1.3 km downstream after about 20 minutes, flood YeMuShi Village and its irrigation district of 1.5 km downstream after 25 minutes, and impose submergence losses to AiDingHu Farm, Qianjing Goups No.1, No.2 and No.3, Branch No.3 of National Farm No.221. Thus a dam failure not only destroys the reservoir project itself but also causes heavy economical losses to the downstream area that will be submerged, even grave disasters of human life without a timely alarm. C. preventive measures and mitigation measures a. fight against collapse and slide. In case of an emergency of collapse or slide of reservoir dam, throw blocks, earth/sandbags or lead (bamboo strip) caged stones. Firstly, throw them to the locations where collapse or slide is quite extensive, then throw them in orders specified, until the bank or slope is stable. b. fight against piping. When leakage paths occur at the dam downstream side or foundation, given small paths, cotton, straw bags, fibre bags or wedges made of straw bound in bundle can be used to calk the paths; given big paths, cotton, straw bags, fibre bags or wedges made of straw bound in bundle can be used first, then the path shall be covered by tarpaulin or net cloth, compacted by earth bags, sandbags and finally sealed with clay tightly. c. fight against leakage. In the event of a leakage, the method of “cut off leakage from upstream side, guide leakage water out from downstream side” is taken. The details are that: at the upstream side, compact the beam with clay material with low permeability or tarpaulin or geotextile membrane to reduce water going into dam body; at the downstream side, use sandstone, geotextile, firewood or straw to play a filter role to prevent the losses of earth fills, so that the phreatic line of dam body can lower down, and dam stability can be kept. It is noted that clay material is forbidden to used at the downstream side, otherwise the phreatic line of dam body would rise up and worsen the leakage scope and emergency situation. d. fight against pitfall. In the event of a pitfall on the dam, clay material packed in the straw bags, burlap bags or fibre bags can be used to fill the pitfall directly, then the pitfall can be filled with clay as the case may be. e. fight against cracks. In the event of a crack and heavy leakage accompanied, a shaft shall be dug along the crack at an interval ranging from 3m to 5m to do cut off. The shaft shall go 0.3m~ 0.5m deeper than the crack and have a bottom width of 0.5m least. At the upstream side, beam shall be made to close the leakage paths; at the downstream side, filter and leakage water guiding out shall be prepared well. f. fight against wave surge. The wave surge in the reservoir could seriously erode the dam and endanger dam safety. Straw mats and straw bundles can be placed on the upstream side to mitigate erosion, or fibre bags and plastic film can be braced by bamboo and extended on the water surface to ease up the wave surge. g. fight against overtopping. In case of a flood in exceedance of design standard or overflowing the dam crest according to the forecast, overtopping shall be prevented by means of following measures: 1. earth-made sub-cofferdam. A sub-cofferdam shall be built up on the dam crest close to the upstream side and 0.5~1.0m away from the dam abutment. Such sub-cofferdam shall be 0.5m~1.0m wide, in a gradient no more than 1:1, and with a height more than the maximum possible flood level. When carry out emergent construction, Page 41 39 first cut a trench along the determined axis of the sub-cofferdam with a depth of about 0.2m and a bottom width of about 0.3m and in a slope of 1:1, then clean up dirot and sundries, finally scarify the trench bottom surface or plough it into small ditches to facilitate the joint between fresh earth and previous earth. Clay material shall be ideal. 2. earth-made sub- cofferdam. Pack earth in the strawbags or fibre bags, to 70~80% of a bag capacity, leave it open, no binding needed, facilitate placement. Bag placement can be done at the place 0.5m ~100m away from the downstream abutment, bag mouth shall be put toward the downstream side, bag seams shall be placed staggered. This sub-cofferdam shall be sloped 1:0.5 at the upstream side with its top higher than the maximum possible flood level. 3. piles-made sub- cofferdam. A row of piles shall be driven at the upstream side of 0.5~1.0m away from the dam abutment at an interval of 0.5m~1m. The exact length of piles shall depend on the height of the sub-cofferdam. Piles shall go into the earth at a depth of ½ of the whole pile length. Tree branches or wooden boards are bound to the downstream side of the piles by means of lead wire or hemp, and then stone blocks and clay are filled thereupon. KeKeYa Reservoir A. risk identification The status-quo of the safety situation of this reservoir’s dam, the field inspection result and the historic failures of concrete-faced dams show that the most possible emergencies of this dam would be as follows: a. flood no more than flood control standard; b. flood in exceedance of flood standard; c. dam failure flood: in the event of a flood over 1000-year- recurrence or equal to a 1000-year-recurrence check; d. in the event of a large-scale mountain collapse, then the spillway blocked impairs normal flood discharge, the reservoir level may rise up during flood period, reach even exceed check flood level, finally dam failure occurs; e. in the event of failure of the gates at the diversion tunnel (which is also discharge tunnel), those gates can be handled normally. B. analysis on risk damages In case of a dam failure, the overtopping flood may ruin KeKeYa river basin management station that is only 0.3km from the dam, run down continuously at a high head along the KeKeYa river valley, draw down within 2m after reaching KeKeYa Village of 3~7 km downstream, and drop within 0.5 m when reaching ShanShan Township of 45km downstream. The overtopping flood will submerge KeKeYa Village. Northwest of ShanShan Township and Railway Lanzhou - Xinjiang, national road No.312, and agricultural irrigation district. Thus a dam failure not only destroys the reservoir project itself but also causes heavy economical losses to the downstream area that will be submerged, even grave disasters of human life without a timely alarm. C. preventive measures and mitigations measures a. establishment of emergency and contingency system ShanShan County People’s Government is the highest commanding body. Its office is located in the ShanShan County river basin management official building. b. emergency headquarters leaders and staff and institutions involved The emergency headquarters is Shanshan County Flood Control Command Centre; it shall strictly follow the principle of administrative chief taking responsibility. The County Chief who is also the chief commander is assigned to be in charge of whole flood control issue. The vice commanders are the leaders from county committee and government. All staff members of the centre are the leaders from related township, national farms, who shall be the chief of those institutions. ShanShan County KeKeYa Reservoir Contingency Page 42 40 Program gives a detailed list describing names, positions and institutions of the leaders and members of this emergency command centre. c. reporting, notification and publication of emergency Once an emergency is shot by the observation people, patrol people or guard people, they shall immediately report it to the commander Mr. Zhu Jing Gang (director of ShanShan County Water Resources Bureau, cell phone: 13909958286) or to the vice commander Mr. Shi Chang Shuang (chief of KeKeYa River Basin Management Station, telephone: 8328666), and record specific location of emergency and its extension, receive the orders released by the commander or vice commander, do observations and inspection more densely, and report the evolvement of the emergency situation. d. emergency inspection patrol Upon the launch of a contingency program, risk relief team shall assign proper human resources based on the actual conditions (2 people least per shift) to keep an eye on the monitoring, measurement and patrol over the locations and extension of the emergency. Those people shall be on the duty around the clock in turn, timely write down emergency and its sequences and report to the commander or vice commander. e. emergent evacuation and temporary resettlement in case of dam failure and flood In case of emergency that would induce dam failure or occurrence of dam failure, the commander shall call for ShanShan County People ’s Government to evacuate the people and property within the scope of flood submergence and provide resettlement properly. The residents at the downstream should evacuate within 30 minutes after the release of an evacuation alarm. In addition, the basic living facilities and standard shall be guaranteed with the people evacuated (including reservoir management staff) covering their living, sanitation, medical, traffic, communication and education. Temporary depositary to receiving the people’s properties (including livestock) and necessary security measures shall be prepared well by related departments and principals. KanErQi Reservoir A. risk identification The status-quo of the safety situation of this reservoir’s dam, the field inspection result and the historic failures of concrete-faced dams show that the most possible emergencies (risks) of this dam would be as follows: a. flood no more than flood control standard; b. flood in exceedance of flood standard; c. dam failure flood: in the event of a flood over 1000-year-recurrence or equal to a 1000-year-recurrence check; d. in the event of a large- scale mountain collapse, then the spillway blocked could impairs normal flood discharge, the reservoir level may rise up during flood period, reach even exceed check flood level, finally dam failure occurs; B. analysis on risk damages The flood routing results of a dam failure show that in case of a dam failure under the check flood level, the overtopping flood may promptly ruin KanErQi river basin management station that is only 0.3km from the dam, run down continuously at a high head along the KanErQi river valley, draw down within 2m after reaching the northeast of HuoCheZhan Township of 13 km downstream, and drop within 1 m when reaching QiKeTai Township of 20km downstream. The overtopping flood will submerge ShanShan County Railway Station, east region of HuoCheZhan Township, east region of QiKeTai Township, Railway Lanzhou—Xinjiang, national road No.312, HaTu oil field and agricultural irrigation Page 43 41 district. Thus a dam failure not only destroys the reservoir project itself but also causes heavy economical losses to the downstream area that will be submerged, even grave disasters of human life without a timely alarm. C. preventive measures and mitigations measures a. establishment of emergency and contingency system chart Based on the staffing of KanErQi river basin management station, the emergency and contingency headquarters will consist of a command center, risk relief team and rescue team as well as headquarters office. b. headquarters leaders and staff and institutions involved The ShanShan County People ’s Government shall be the highest body among the entire emergency and contingency system responsible for the KanErQi reservoir dam safety management. Its office is located in the ShanShan County KanErQi river basin management official building. Such headquarters and commander shall play a leading and coordination role in case of an emergency. c. establishment of a command centre The main responsibilities of this center is to keep close contact with the ShanShan County People’s Government, ShanShan County Water Resource Bureau, ShanShan County People’s Government Flood Control and Drought Relief Headquarters, ShanShan County armed police force and the downstream possemen; release the order of launch and end of a contingency situation; fully lead the application of contingency program and running of headquarters; organize experts to discuss the situation; put forward a rescue plan; conduct emergency dispatching, mobilize rescue team and material; coordinate with Shanshan Railway Station, HuoCheZhan Township, QiKeTai Township and TuHa oil field at the downstream of the dam and release people evacuation order. The name list and contacts are shown in the table of KanErQi Reservoir Contingency Program. d. risk relief team The main responsibilities of this team are to be responsible for the safety, security and anti terrorist of KanErQi reservoir dam and its affiliates; do patrol, monitoring and alarm upon a risk of the dam, report and transfer related information; do a good job assigned by the headquarters, call for a hand from TuHa oil field public security bureau and the armed possemen of HuoCheZhan Township and QiKeTai Township; and call for help from the people’s armed force department, armed force, policies of ShanShan County. e. rescue team The main responsibilities of this team are to recruit risk relief team’s human resources and in charge of the security at the entrance into the dam. f. headquarter’s office There is an office under the headquarters responsible for routine issues. g. downstream emergency and rescue team In case of an emergency but inadequate working staff members, call for the help from TuHa oil field public security bureau and the armed possemen of HuoCheZhan Township and QiKeTai Township. The emergency and rescue team at the downstream of the KanErQi reservoir can consist of the people from ShanShan County Armed Force Fire Fighting Unit, armed possemen of HuoCheZhan Township and QiKeTai Township, staff members of Page 44 42 industry line, mine line and enterprises, medical personnel and ordinary masses. This team shall follow the orders of the headquarters. The number of people and equipment of this team shall be provided based on the grade of an emergency. All team members shall meet at the place designated by the headquarters, and take the bus to the reservoir site to carry out risk relief and relief actions. In case of an dam failure flood, the team shall help the residents within the downstream submergence area to do evacuation and carry their property out. 4.1.1.4.4 Risk of radioactivity 1analysis on the ri sk Pertinent investigations indicate that there is a slag left by previous Yuergou Coal Mine and No.505 Mine in the river course of the Yuergou River Basin at the north of the Alagou River. The slag of the mine tailings contains radioactive matters. When quarrying and borrowing of aggregates for the construction of Alagou Reservoir, the aggregates mixed with mineral slag may be quarried together, this would impose a probability of unfavorable impacts on the health of project construction people and reservoir management staff. 2preventive measures set up a security belt around the stacking place of radioactive matters and potential radioactive zone, strictly forbid to quarry aggregates and borrow soil from the river course at the downstream of Yuergou Coal Mine slag; set up a clearly visible alarm board at the perimeter of this area; do a good job of dissemination and training for the construction people, tell them the existence of radioactive matters, incidence and serious consequence. The cost of this part has been list in the line of routine activities. 4.1.1.4 Impact of plant diseases and pests After the service of water conservation project, the change in the irrigation way could increase the utilization of agricultural chemical products in the project area and bring on negative environmental impacts to some extend. In view of this unfavorable impact, a separate Disease and Pest Management Plan is included in the project. Following measures will be taken in the water conservation project area to limit the increment of agricultural chemical productions and its negative impacts on the regional environment during future operation period of the project. Mitigation measures: during the implementation period, take a composite method to integrate together the pesticide use, agricultural control, physical control and biological control. the use of pesticide shall follow the principle of economy, safety and effect. Turpan Prefecture WB PMO shall keep contact with the plant protection and quarantine stations at prefecture, city and county levels, and request them to recommend high effective and low poisonous pesticide.

Design results during this stage will be the fundamental reference for project build, implementation and operation. The design shall consider the project from project itself and environmental protection two prospects, optimize design schemes, and carry out selection and optimization in terms of project site selection, arrangement of disposal yards, construction conditions and construction ways so as to minimize the scope of disturbance and interference, reduce the quantities of permanent mucks and avoid or cut down unfavorable impacts on the environment during construction period and operation period. Besides, from the perspective of environmental protection, the basic ecological discharge and discharge way are proposed in respective EIA reports based on the actual conditions of the river basin where the reservoir alike projects will be built. (1) Meiyaogou Reservoir Project Meiyaogou Renmin Canal Headworks was built in 1950s-60s. It is the first water retaining and conveyance works on the Meiyaogou River. However, the water diversion conducted by the Renmin Canal Headworks dries up the downstream river reaches. The runoff could not reach the downstream reaches except that the flood in the upstream is very big and can’t be handled by the canal completely. It is obvious that the service of Meiyaogou Renmin Canal Headworks has converted the Meiyaogou River into a channel, and the river courses downstream the headworks are dry up generally. The proposed Meiyaogou Reservoir dam site will be located at the place of about 4 km downstream to the Renmin Canal Headworks. There is no aquatic life and distribution of forest and grass along the river course downstream the proposed dam site, which needs Page 46 44 nothing ecological discharge demands. In addition, the development of this project will not extend dry-up river course and dry-up period. In this case, the development of this project will have no requirement of basic ecological discharge. 2 Ertanggou Reservoir Project Determination of basic ecological discharge Since the river reaches downstream of the proposed Ertanggou Reservoir dam site have no special and sensitive ecological water demands, only basic ecological discharge is required. The ecological water demands are determined by means of the calculation method recommended in the Technical Instructions for Evaluation on the Environmental Impacts of Ecological Discharge, Low Temperature Water and Fish Passing Facilities in Hydropower and Water Conveyance Projects (provisional) issued by the Ministry of Environmental Protection of the People’s Republic of China. French “Country Method” is used to determine the ecological water demands of the river reaches. It is specified in this Method that the minimum ecological discharge should not be less than the 10% of the mean annual average discharge. The mean annual average discharge at the proposed dam site of Ertanggou Reservoir is 2.52 m 3 /s, its ecological discharge is taken at 0.25 m 3 /s. Evaluation on the satisfaction degree of basic ecological discharge cut at the cross section of Ertanggou Reservoir dam site Based on the status-quo of river course, the river reaches downstream of the dam site will be diverted through gates No.0 & 1. Since the river reaches below the gate No.1 have been dry up, the basic ecological discharge shall least maintain a continuous flow along the river reaches of 4.6 km long between the cross section of dam site and gate No.1. The monitoring and measurement data available from the Ertanggou Hydrological Station indicate that the mean annual average flow through the station controlled cross section (located at 100m upstream to the project dam site) is 0.22 m3/s in March, which is the smallest value throughout a year. Because the temperature is quite cold in March, no diversion will be done through gates No.0 & 1 to protect headworks; It is introduced by the management station people that there has been no dry-off phenomenon at the gate No.1 in March. Thus, based on the actual conditions, the discharge of 0.25 m3/s can maintain a continuous flow along the river reaches of 4.6 km long between the cross section of dam site and gate No.1. Hence, the basic ecological discharge determined with the project will not extend dry-up river course and dry-up period of the Ertanggou River. guarantee of basic ecological discharge of Ertanggou Reservoir The design of main civil works that a glass lined steel pipe in a diameter of 500 mm will be erected at the outlet of irrigation discharge tunnel, and routed along the dam access road to the dam downstream riverbed, this pipe will provide the basic ecological discharge. The irrigation discharge tunnel will be designed to have an invert at El.1435m, while the reservoir will have a minimum pool level of El.1439.00m, the invert is lower than the minimum pool level, thus this project can guarantee a basic ecological level through the dam cross section at any time. 3 Alagou Reservoir Project Page 47 45 Determination of basic ecological discharge Suffering the impact of reservoir dispatching, regional ecological water demands will be influenced unfavorably due to the reduction of flow in local downstream river reaches. The river reaches with flow reduced will be about 3.6 km long between dam site and the confluence of Alagou and Yuergou, and there is no flow contribution from other basins. Hence, a certain discharge shall be considered with this river reaches to maintain a basic ecological discharge and keep continuous flow along the river course. Since the river reaches downstream of the proposed Alagou Reservoir dam site have no special and sensitive ecological water demands, only basic ecological discharge is required. It is specified in the French “Country Method” that the minimum ecological discharge should not be less than the 10% of the mean annual average discharge. The mean annual average discharge at the proposed dam site of Alagou Reservoir is 4.06 m 3 /s, its ecological discharge is taken at 0.4 m 3 /s. Evaluation on the satisfaction degree of basic ecological discharge cut at the cross section of Alagou Reservoir dam site The 50-year series monitoring and measurement data available from the Alagou Hydrological Station indicate that the mean annual average flow through the station controlled cross section is 0.4 m 3 /s in March. It is introduced by the management station people that there has been no dry-off phenomenon along the river longer than 3.6 km between the station and river out of the valley. Thus, based on the actual conditions, the discharge of 0.4 m 3 /s can maintain a continuous flow along the river reaches. Hence, the basic ecological discharge determined with the project will not extend dry-up river course and dry-up period of the River. guarantee of basic ecological discharge of Alagou Reservoir Since the basic ecological discharge of this project is less, it is recommended that a siphon conduit shall be erected to delivery water to the downstream. This siphon conduit can be adjusted to get a good water intake position to ensure a smooth basic ecological discharge. However, this measure is subject to people’s behaviors, it is recommended to strengthen management and monitoring by engineering administration department and Tuokesun County Environmental Protection Bureau during project operation period and aperiodically inspect the discharge measures so as to guarantee making in place those discharge measures. 4.1.2.2 Environmental Impacts during Construction Period For possible adverse impacts that may commonly exist in the course of implementation of the World Bank Financed Turfan Prefecture Water Conservation Project, see Table 4.1-2. Page 48 46 Common Adverse Impacts on Environment During Implementation Table 4.1-2 S N Source item Adverse environmental impact Productio n waste water has adverse impact on local surface water environment, surface vegetation, and soil. 1 W a t e r e n v i r o n m e n t Domestic sewage If domestic sewage is not strictly treated and strictly discharged, it will not only pollute the surface water and groundwater in the neighborhood but also breed mosquitoes and flies and spread bacteria and, as a result,risk the health of the construction staff and damage ecological and living environment. Exhaust gas during constructi on Exhaust gas from fuel-powered machinery and waste gas from coal burning in construction work and life of construction staff will have adverse impact on those who work with intensive machinery operation for a long time. 2 A t m o s p h e r i c e n v i r o n m e n t Dust emission during constructi on Construction, excavation, highway transportation and so on may emit dust to create adverse impact on the atmospheric environment and mainly on the construction staff around the construction site. 3 Acoustic environment During construction, noise pollution mainly comes from constant noise such as produced by mixer plants, blending machines, sieving plants, belt feeders, and so on, from non-constant noise such as strong noise produced by blowing up, which is very loud, and from dynamic noise produced by construction machinery such as dump trucks, water wagon, load-carrying vehicles, and so on. Noise mainly has impact on construction staff. 4 Solid waste Solid waste generated during construction mainly includes spoil, debris, and so on and domestic waste from construction staff. Large quantities of spoil will be generated from production during construction. If relevant measures are not taken to protect against it, a lot of soil and water losses will be caused. Domestic waste mainly comprises fruit peel, paper scraps, vegetable leaves, refuse, and so on discarded from the daily life of the construction staff, which have high content of organic matter. Randomly piling and dumping domestic waste will affect the living environment and health of the construction staff as well as create adverse impact on local landscape environment. 5 Ecology and environment impact on soil: permanent land occupation will completely change the type and properties of the surface cover within the occupied area and the surface soil will be unrecoverable permanently. During construction the surface soil on the gravel and earth borrow sites will be removed and should be backfilled with the original surface soil at the end of construction. In the process of soil backfill, the compactness, permeability and physical properties of the soil will be affected by disturbance of machines and so on. impact on vegetation: the surface vegetation within the permanent land occupation and reservoir inundation areas will be permanently replaced. Temporary land occupation tend to cause soil and water losses due to destruction of the surface cover and vegetation. Therefore, temporary protection work should be done well during construction. Besides, concentrated discharge of production and domestic waste water will also adversely affect the vegetation if not properly disposed of. impact on wild animals: wild animals within the construction areas are mainly the usual rodents and small reptiles. The reservoir construction will have impact on wild terrestrial animals mainly through construction noise, land occupation, reservoir inundation, and activities of construction staff in the neighborhood of the reservoirs and their planned areas. Page 49 47 6 Soil and water loss Within the land occupation areas surface soil and vegetation are destroyed, which will increase exposed area and intensify soil and water losses. During excavation, the loose earth and stone piled and backfilled provide materials for wind erosion and water erosion and accelerate soil and water losses in the construction areas. If not taken good care of, temporarily kept spoil during construction will emit dust when there is a strong wind and, as a result, affect the health of the construction staff and cause soil and water losses. 7 Health of people When a large number of construction staff gather together, there will be high chance of creating conditions for incidence of enteric infectious diseases and respiratory infectious diseases, which will affect the health of the construction staff, if sanitation and living conditions are poor or hygiene and disease control are not in place. 8 Cultural relics Construction and excavation may be concerned with cultural relics. Page 50 48 4.1.2.3 Environmental Impact during Project Operation Period During the operation of World Bank Financed Turfan Prefecture Water Conservation Project, the subprojects that have adverse impact on environment are mainly reservoir construction schemes. The subprojects of water saving irrigation, canal construction or reconstruction and Kariz system preservation will not create adverse impact on the ambient environment. For possible common adverse impacts of reservoir construction on environment, see Table 4.1-3. Common Adverse Environmental Impacts during Operation Table 4.1-3 SN Source item Adverse environmental impact Hydrological regime in reservoir areas After inundation of the reservoir, water level will rise significantly from the front to the tail of the dam. Area of water surface also becomes vast from the previous frequent dry-up or narrow area, which will change the terrestrial habitat into aquatic habit. Due to the high water level and deep water body, the gradient ratio of water surface becomes small and flow slow in the reservoir. 1 H y d r o l o g i c a l r e g i m e Hydrological regime downstream Hydrological regime in the rivers downstream is changed from natural runoff into artificially regulated runoff. The reservoirs will effect regulation in accordance with the production demand of various sectors and the incoming water in the natural rivers. Owing to the regulation and storage of the reservoirs, the monthly runoff distribution within a year in the rivers downstream will change. Water temperature in reservoir areas The construction of the project will change the water temperature pattern in the rivers of the reservoir areas. 2 W a t e r t e m p e r a t u r e Temperature of water discharged downstream The temperature of the water discharged downstream form the reservoirs will be higher in spring, which will be good for crop growth in the irrigation areas downstream. In summer, the temperature will be a little lower, but the atmospheric temperature in Turfan in summer is high, so is the earth surface temperature, which will heat the irrigation water. Besides, the water discharged downstream form the reservoirs will need to flow through more than 20 km open canals in its delivery, which makes water temperature go up gradually. Therefore, the temperature change of the water discharged downstream form the reservoirs will not affect agricultural production very much. 3 Water quality After inundation of the reservoirs, the water body will expand dramatically, water will flow slowly and the capacity is greater. Then the sediment of suspended matter will be stronger and the concentration of suspended matter is lower. Without increasing pollutants discharge, the quality of the water in the reservoirs will basically remain the same. In order to prevent worsening of water quality, the bottoms of the reservoirs should be well dredged before water storage. Strict measures must be taken to treat the domestic waste water generated during project operation. The treated water will be utilized in a comprehensive manner and may not be discharged into the rivers. 4 Solid waste Solid waste mainly comprises fruit peel, paper scraps, vegetable leaves, refuse, and so on discarded from the daily life of the reservoir management staff, which have high content of organic matter. Randomly piling and dumping domestic waste will affect the living environment and health of the reservoir management staff as well as create adverse impact on local landscape environment. 5 Dry-up of rivers Affects downstream water environment and aquatic ecology. Page 51 49 4.2 Mitigation Measures 4.2.1 Reservoirs 4.2.1.1 Mitigation Measures During Project Design 4.2.1.1.1 Common measures Following measures will mainly be taken to mitigate environmental impacts of the project during the design of the three reservoirs: 1 environmental justification analysis of the selection of the dam sites; 2 en vironmental justification analysis of the selection of the borrow sites; 3 environmental justification analysis of the selection of the spoil disposal sites; 4public participation in surveys The above-mentioned measures taken for each of the reservoirs will vary. For specific information, see 4.2.1.1.2. 4.2.1.1.2 Specific measures 1 Meiyaogou Reservoir During the design of Meiyaogou Reservoir, consideration was given as much as possible to environmental protection requirements in terms of comparison and selection of the dam site, selection of the spoil disposal site, construction design organization, so on, so as to achieve the maximum benefits with the least possible disturbance and change in environment. Selection of dam site At this stage, two optional dam sites, i.e. a upper site and a lower site, are preliminarily compared and selected. The upper and lower sites have basically the same conditions and neither has environmental constraints. The type of occupied land of both sites is also basically the same and the upper one will inundate less area than the lower. The impact of inundation can be mitigated through compensation measures. The excavation at the C4 and C5 borrow sites of the upper option can be utilized. The upper site will enable water delivery by gravity, which will save staff and energy input. At the same time, the upper one will involve more earthwork, which will cause more soil and water losses, but the impact can be mitigated through soil and water conservation measures. The construction of the dam at the upper location may create impact on the villagers of Meiyaogou, but it can be mitigated through strict management measures. Therefore, it is believed that the recommended upper site is environmentally reasonable. Environmental just ification analysis of the selection of the borrow sites; Page 52 50 At the current stage, the selected C3 gravel borrow site is located in the river bed and Level I terrace of the reservoir; C4 borrow site rests in the left side of the dam; and C5 borrow site lies in Level III terrace on the right bank. There is no vegetation in either C3 site or C4 site while in C5 site there are trees planted by people. With regard to C3 borrow site in the reservoir area, the river bed is dried up with only a few shrubs growing down there. At the time of excavation, the headwork of Renmin Canal will be used for diversion, which will reduce scouring of water. Before geo-membrane is laid, the reservoir basin should be leveled. Therefore, the exploitation at this borrow site will not create major impact. C4 site is located on the left bank, where there is basically no vegetation. The exploitation will facilitate the stability of the reservoir bank, expand the reservoir storage capacity, and the excavation will be utilized. At the time of exploitation, soil and water losses should be prevented with care, which will not create major impact. C5 borrow site will be excavated on the Level III terrace on the right side of the river bed so as to increase the reservoir storage capacity. In this place there are some abandoned factory workshops and a woodland in the southern area. The site can serve as both a borrow site and an inundated area of the reservoir. It will be compensated for in the form of money. For environmental justification analysis of each of the borrow sites, see Table 4.2-1 below. Table 4.2-4. Analysis of Environmental Rationality of Material Ground Site Selection In conclusion, the selection of the borrow sites is basically reasonable. In accordance with the survey, there are some dregs from the previous Yuegou Coal Mine Items Sand/gravel material ground Rock material ground Earth Material Ground Evaluation of Environmental Rationality Is it within environmentally sensitive area (ESA) such as nature reserve, zone of famous scenery, zone of cultural heritage? None of these material grounds is within ESA. Rational Is it at site of important resources such as basic farmland and land of special local product and so on? The earth material ground will be located on a piece of dry wasteland outside zone of basic farmland. The sand/gravel material ground at Yuegou will be located on a piece of Gobi desert and flood plain, while the sand/gravel material ground at the dam site is on the river bed. These 2 material grounds have nothing to do with basic farmland. Therefore, the material grounds are not at site of important resources Rational Is it within environmental risk area with problems such as land collapse, slope slide, mud-rock flow, flood discharge, big wind passage and so on The geological condition at the place where all the material grounds are located is stable. They are not within environmental risk area. Rational Are the environmental sensitive targets impacted? There is no environmental sensitive target close to any of the material grounds, the targets such as residential area and rare vegetation. Rational Is it possible to rehabilitate the landscape, vegetation and land? The earth material ground will be located on a piece of dry wasteland, the sand/gravel material ground at Yuegou will be located on a piece of Gobi desert and flood plain and the sand/gravel material ground at the dam site is on the river bed. The original vegetation is very limited. The development of material grounds has very limited impact on the local vegetation, but the local vegetation will be rehabilitated after the use of the material grounds. Basically rational Does the transport route pass through any place that should not thus impacted, the places such as urban district, residential area, school and so on? None of the transport route for the material grounds will pass through any place that should not thus impacted. Rational Page 53 51 and Mine-505 at the riverbed of Yuegou Catchments at the north of Alagou District. The tailings and spoil content 3 radioactive substances such as uranium, thorium and radium-226. The dregs are the small quantity of tailings and spoil mixed in the sand and gravels on riverbed after clearance. Although the radioactivity dosage is relatively small, there are still possible impacts on the regional environment and public health. To avoid any risks of radioactivity, therefore, it is suggested to forbid excavating sand, gravel or earth material downstream the tailings and spoil at the riverbed in Yuegou. Rational Analysis of Waste Dumping Site Selection There will be 292,100 m 3 of engineering spoil from the project. It is planned to have one set of waste dumping site (7.8 ha) in the gully 5 km from the railway at the right bank. The elevation of the original ground is 804 m, and the waste dumping will make an elevation of 810.5 m. This waste dumping site will be located at a piece of lowland in the gully. There is no rare vegetation/wild animal or residential area within or around the impacted area of the waste dumping site. From the viewpoint of environmental protection, the site selection is reasonable. However, the dumping site must be protected during its functional period in favor of soil conservation. Public Participation Public participation aims at soliciting the opinions of the impacted public on environmental issues before/during/after the project construction so as to improve the project design. The EIA staff for Alagou Reservoir construction has twice carried out activities of public participation. The first action was made one week after they were entrusted, while the second action was made after drafting EIA report. Considering different target groups, multiple measures of public participation were taken such as posters, questionnaires, interviews and forums. The overall considerations of the public are: A. Alagou Reservoir construction will play a very important role for the development of Tuokesun County. It will effectively alleviate the pressure of water supply to irrigation and petroleum extraction in favor of local socio-economic development, livelihood upgrading and social stabilization. B. Generally speaking, Alagou Reservoir construction will not have much impact on the environment. Although there will be less water downstream the dam site, this will no become a big adverse impact on the environment. At the same time, the public contributed some proposals to Alagou Reservoir construction: A. It is proposed to strengthen environmental protection (especially the protection of www environment) during the construction period, so that water pollution in Alagou River due to the construction will be avoided and the quality of water use downstream will not be impacted. B. With diverging water from the mainstream of Alagou River, the ecological environment and scenic environment downstream the dam site will be impacted. Therefore, the project should pay attention to both the development and protection to make sure there will be no Page 54 52 dry-up downstream the dam site. C. The engineering staff should highly respect the custom and habits of the indigenous people, take serious consideration of the vital interest of the local farming herdsmen, and be strictly abided by the legal regulations of environmental protection. Management of the solicited opinions in the public participation : A. The key point of environment protection during the construction period is the protection of water resources. For this, EIA report of Alagou Reservoir construction has pointed out target-oriented measures of environment protection. The required budget has been integrated into the overall budget of the project construction. At the same time, an action plan of environment management and supervision during the construction and operation periods has been formulated, in which responsible person, executor and supervisor are arranged. B. EIA report of Alagou Reservoir construction has pointed out the quantity and patterns of ecological baseflow discharge at the cross section of the dam site during the project operation. C. To satisfy the requirement of the local public for good social security during the project construction, the management of the workers will be strengthened and how to respect the custom and habit of the indigenous people will be one of the items in capacity building so as to keep the local social security in good order. 4.2.1.2. Mitigation Measures in the Construction Period In terms of the main structures and construction pattern, the 3 reservoirs to be built in the project look basically the same. Since they are located in different natural environment and social environment, the environmental issues in each of them are different. Therefore, the countermeasures have both something in common and in difference. 4.2.1.2.1. Countermeasures in Common 1 Measures for Water Environment Protection Conventional explosives in engineering have relatively big impact on water quality. In order to mitigate the impacts of nitro-explosives on water quality, it is proposed to use emulsion based explosives, water/binder explosives or other environment-sound explosives. In order to make sure of the effective operation of the wastewater treatment station, the construction and effective operation of the wastewater treatment station should be included as one of the clauses in the project contract. The environmental management sector of the project should make regular checks and supervisions in the field to timely handle the situation of wastewater treatment and rectify any problems observed in forms of oral and written recommendations. Reservoir bed should be cleared. With the above measures, the nearby water body can be protected from contaminations by the construction wastewater and domestic sewages. Page 55 53 2 Measures for Air Environment Protection Dustproof Measures A. Earthwork and Stonework In excavation activities at dam site and material ground, measures such as of dust control water spraying (mainly at the excavating, dumping and loading sites) will be taken to accelerate dust deposition and reduce the time span and scope of the dust impact. The quantity and frequency of water spraying will be set according to the weather conditions and dusting situation. B. Dust Treatment at Concrete Preparation The concrete preparation system should be supported by dust control water spraying around to reduce the time span and scope of the dust impact. C. Dustproof at Roads and During Transportation Vehicle dust is generated mainly from road surface, road damage and the goods on a running vehicle. It can be reduced when effective control measures are taken. Air pollution should be prevented in the process of transportation. When transporting a dusty material, the material should be properly moistured or covered with canvas. When transporting bulk cement, the tank should be well sealed. When transporting bagged cement, it must be properly covered. In addition, the vehicles should be frequently cleaned. Damaged road should be timely repaired, and the temporary roads at construction sites should be covered with pebbles so as to reduce dust. D. Water-Spraying Vehicles The construction sites should be equipped with water-spraying vehicles especially at the material excavating, stacking and loading sites as well as roads. The quantity and frequency of water spraying will be set according to the weather conditions and dusting situation. E. Labor Protection In accordance with the national stipulations on labor protection, on-site engineering staff should be access to dustproof respirator. Control Measures against Waste Gas from Machine The waste gas emission of construction vehicles and machines is of intermittent and mobile features. The vehicles and machines should be well managed: A. In order to reduce the emission of CO 2 and NO 2 in favor of air protection, machines and vehicles in line with the national standards relevant should be employed in the project construction, so that the waste gas emission will below the limit of national standard. B. On the basis of Car Scrapping Programs, mandatory update will be practiced to the poor vehicles of high consumption, low efficiency and the tail gas emission seriously exceeding the limit. Page 56 54 C. The machines will be maintained in good conditions. Waste Gas Management in Tunnel Engineering Tunnel engineering will generate toxic gas and much dust and the environmental conditions in a tunnel restrict the waste gas and dust from diffusing, which is quite harmful for the health of engineering staff. Therefore, the sections of drilling and exploding practices are equipped with ventilation and dust removal equipment such as axial-flow fans and air purifiers. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of waste gas and dust on the health of engineering staff and air environment will be effectively reduced. 3Measures of Noise Control The engineering staff will be access to earplug, ear protector, cotton and headpiece of noiseproof according to the actual conditions. The roads and vehicles will be properly repaired and maintained to redu ce noise. The vehhicle to be employed will be of low noise and in line with regulations such as Limits of Noise Emitted by Stationary Road Vehicles (GB16170-1996) and Limits and Measurement Methods for Noise Emitted by Accelerating Motor Vehicles (GB1495-79). Machine base of vibration reduction will be used for an equipment with large vibration. Evaluation of Measures : With the above environmental mitigation measures, the impacts of noise on the engineering staff will be reduced to an acceptable level. 4Treatment of Domestic Garbage Mobile recycling collection points and garbage bins will be arranged at the temporary living quarters, and these sanitation facilities will be regularly managed to prevent and reduce mosquitoes and flies. Garbage truc k will be equipped to carry the domestic garbage for landfill disposal. Information publicity on sanitation will be strengthened for capacity building of sanitation and environmental protection among the engineering staff. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of domestic garbage on the environment will be greatly reduced, and there will be no permanent impact on the environment. 5Measures in Favor of Ecological Environment Protection of terrestria l plants The construction activities will unavoidably generate some impacts on the plants. To mitigate the impact, the scope of construction sites and living quarters will be clarified according to the general arrangement plan. After the completion of engineering activities, the Page 57 55 temporary facilities of construction and livelihood will be demolished, and these sites together with the material grounds will be leveled for vegetation rehabilitation. The practical measures are illustrated in the chapters of soil conservation of the project reports. The compensation for the inundation and occupation of farmland and forest land in the project will total to 51.7671 million yuan, including 8.46 million yuan for Meiyaogou Reservoir, 23.8182 million yuan for Ertanggou Reservoir and 19.4844 million yuan for Alagou Reservoir. Protection of terrestrial animals A. In the construction period, information publicity of ecological protection will be strengthened among the engineering staff and the local people by means such as of leaflets and information boards to reduce impact on wild animals. B. A mechanism of punishment against damaging ecological environment will be set up. Any of the engineering staff is forbidden to hunt wild animal. To mitigate the impact, the scope of construction sites and living quarters will be clarified according to the general arrangement plan. Fire will be forbidden outside the construction sites. C. Most of the wild animals look for food in the morning, early evening or at night, and noon is the time for rest. In order to reduce the disturbance of engineering exploding against wild animals, the pattern, quantity and time of the exploding activities should be well planned. D. Supervision on environmental protection will be strengthened. Supervision institution of environment protection will be set up and be equipped with full-time staff. The engineering staff will be upgraded with environmental protection education. Any illegal hunting of wild animals will be punished according to the law. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of the construction on ecological environment will be reduced to an acceptable level. 6 Health Protection during the Construction Period Sanitation Management at the Living and Management Quarters After the civil construction of temporary living quarter and management quarter is completed, the sites should be cleared. The sewage pit and garbage should be treated for landfill disposal after disinfection with lime. Protection of Drinking Water Drinking water will be purified and disinfected. The practical measures will be: After sedimentation and filtration, chloride of lime is added into the water for disinfection. The residual chlorine in water above 0.3 mg/l after 30 minutes will be effective to eliminate pathogens of infectious intestinal diseases in water. Then, the water is safe to drink. Since river is the only water source for construction and livelihood, the water quality is easily impacted. Therefore, the water source should be protected. The measures will be: No temporary facility such as of living quarter, management quarter or construction sites as well as toilet, seepage pit, garbage pile or other dirt will be allowed 100 m within around the water source. Page 58 56 Treatment of Garbage, Feces and Sewage The domestic sewage, construction wastewater and garbage will be properly collected and treated. Pest Control Sites of poor sanitation are good places for vector animals such as mosquitoes, flies and rats. Then, the opportunities to be infected will increase. Therefore, attention will be paid to controlling these pests in the living quarters. Prevention and Quarantine Before entering the construction sites, all the cooking staff and the sampled engineering staff should pass the medical examination. The rate of random sampling will be 15%. Evaluation of the Measures: With the above sanitation and medical measures, the health of the construction people will be safeguarded. Crowd -dispersal from Blast Site Explosives will be operated by person specially assigned for them. Blast site must be closed with color stripes to warn people of the danger zone. All the people must be dispersed before an exploding activity. 7Cultural Relics Once cultural relics are found during the construction, the sector of cultural relics protection should be immediately informed of the event and the site should be well-protected. The engineering will continue when the cultural relics is properly managed. The cost thus generated will be shouldered by the project itself. 8 Information Publicity of Environmental Protection Before the construction, information publicity and education on the legal regulations and the project guidelines of environmental protection will be done among the engineering staff to upgrade their awareness of environmental protection. The approaches will include lecturing, material distribution and information boards. Evaluation of the Measures: The measures of information publicity can practically upgrade the engineering staff of their awareness of environmental protection. These activities should be done throughout the project construction. 9 Risk Prevention Measures in the Construction Period Prevention and Control Measures for the Transportation, Store and Use of Explosives, Oils and Other Dangerous Goods A. In accordance with the relevant regulations from Ministry of Public Security, the transport of dangerous goods should be carefully planned before the transport and well handled in the whole process. The planned activities will include the routes, vehicle and time of transport as well as transport escorts and hand-over and acceptance. Page 59 57 B. According to the current regulations on storing dangerous goods, the user is required to submit the quantity of daily use to the supply, who will deliver the dangerous goods according to the plan of daily transport so as to avoid long time store of dangerous goods. C. The stipulations for the use of dangerous goods will be strictly followed. The operator must have induction eligibility. D. It is very hot in Xinjiang summer. The vehicle to transport dangers goods should be protected from insolating. Proper time of transport should be selected and proper measures of cooling should be taken. E. Management of transportation safety will be strengthened. Only the drivers of good skill and high sense of responsibility will be arranged to transport dangerous goods for safe driving F. Once there is an accident when dangers goods leaks in a river in the transport or when the river water is polluted by construction wastewater and/or domestic sewage, the water quality at the accident area should be checked immediately, and the diffusion and impact scope should be investigated. The communities and governments downstream should be timely informed of the accident to prevent the people and crops downstream from hazard. At the same time, this should also be reported to the upper authorities. G. Once there is an accident of oil leakage or there is an explosion accident, the accident area should be immediately evacuated of people. If the road or river is blocked by the explosion accident, the traffic congestion should be eased and the river should be dredged up. H. Professional team should be designated to investigate and evaluate the accident. The report will be one of the evidences for decision-making. I. Explosives and other very dangerous goods will be managed and operated by person specially assigned for them. 100 m around explosive store will be recognized as dangerous area and security cordon is arranged. In explosion operation, 100 m around the explosion zone will be evacuated and closed. Management of Wastewater from Fire Fighting A. The management staff of the power station will be upgraded in the awareness of fire safety through information publicity and education. B. Management regulations of safe production will be formulated and executed. C. There should be drainage around the oil storage. At the end of the drainage, a concrete tank with a volume of 1.5 times of the maximum water use in a fire fighting will be constructed to collect the wastewater from fire fighting. It is forbidden to randomly discharge the wastewater from fire fighting. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of the accident will be reduced to minimum level. 4.2.1.2.2. Target Features and Countermeasures Page 60 58 1 Management of Water Environment Treatment of Construction Wastewater A. Treatment of the wastewater from sand/gravel washing a. Construction of Meiyaogou Reservoir The procedures of wastewater treatment are illustrated in Fig 4.1-1. The wastewater flows from sand washing machine into wastewater regulation pool. The wastewater with high suspended solids is pumped to fine sand recycling processor, in which 80% of the fine sand with diameter above 0.035 mm is recycled. The screen filtered water flows into sand basin for the 1 st sedimentation. After adding flocculant, the supernatant flows into sand basin for the 2nd sedimentation. Finally, supernatant will be used after flocculation and sedimentation.

Procedures of Wastewater Treatment on Washing Sand/Gravel for Meiyaogou Reservoir The sand/gravel processing system for the construction of Meiyaogou Reservoir will be located at the river bed downstream the main dam. One set of sand basin and one set of flocculation and sedimentation tank will be constructed. They will be directly excavated without anti-seepage. On the basis of containing the wastewater for 2 days, the specification of sand basin will be length x width x depth = 20m×10m×2m, while the specification of flocculation and sedimentation pool will be length x width x depth = 20m×10m×2m. In the intermittent phase of sand washing, the water in sand basin is pumped out. When the slurry becomes dry, it is excavated and carried to dumping sites. After the completion of Meiyaogou Reservoir construction, the sand basin and flocculation and sedimentation pool will be backfilled flat. b. Construction of Ertanggou Reservoir The procedures of wastewater treatment are illustrated in Fig 4.2-2. The wastewater from sand/gravel process flows into fine sand recycling processor, in which 80% of the fine sand with diameter above 0.035 mm is recycled. The screen filtered water flows into sand basin for the 1 st treatment and to the sedimentation pool for the 2 nd treatment. After twice sedimentation, the treated water will be pumped into water tank for re-use.

When the slurry in the sedimentation pool becomes dry, it is excavated and carried to dumping sites. The main structures in the designed system will be sedimentation pool, sludge drying pool and construction water pool. 2 sets of sedimentation pools ( 12m×10m×3m) will be excavated between the sand/gravel processing zone and concrete preparation zone. Since coarse sand takes larger proportion in the suspended solids in the wastewater from sand/gravel washing system and concrete preparation system, the sedimentation capacity is large. The technical specification can be satisfied, after the wastewater with high suspended solids pass through a static sedimentation for 1.5 hours. 2 operators will be required in the wastewater treatment. The sludge will be transported by 5 ~ 10t vehicles. Page 63 61 Evaluation of the Measures : With the above environmental mitigation measures, the impacts of the wastewater from the sand/gravel washing systems for the construction of the 3 reservoirs will be reduced to the level that the nearby water body will not be polluted. B. Wastewater Treatment in Concrete Preparation System After evaporation and infiltration, the suspended solids in the wastewater from the sand/gravel washing system and concrete preparation system will spread over the ground in form of crust. It should be cleared after the completion of the construction. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of the wastewater from the sand/gravel washing systems for the construction of the 3 reservoirs will be reduced to the level that the nearby water body will not be polluted. C. Treatment of Oily Wastewater The structures for the treatment of oily wastewater will be composed mainly of sedimentation pool and water tank. A rectangular pool will be constructed near a machine repair station to collect oily wastewater. Oil removal material will be arranged at the entrance of the pool. The oily wastewater flows into the pool through the oil removal material by gravity. When the pool is filled up, the floating oil is collected. After the oil wastewater stays in the pool for 12 hours, it is discharged into water tank for re-use. There is no need for mechanical maintenance in this simple structure. In the operation, the oil removal material will be regularly cleaned or replaced, and the floating oil will be timely collected.

It is proposed to built a septic tank of Model 10-40B10. The treated water will be collected into an anti-seepage water tank (600m 3 ). The treated water can be used for watering vegetation, in which the water disappear through evaporation and there will be no impact on the water body nearby. Evaluation of the Measures : With the above environmental mitigation measures, the impacts of the domestic sewage from the construction of the 3 reservoirs will be reduced to the level that the nearby water body will not be polluted. E. Reservoir Bed Clearance a. Meiyaogou Reservoir In accordance with the technical requirements for using geotextile membrane, the structures in the reservoir area will be demolished, the trees being cut and the floating debris being cleared. After the structures are pushed down, the construction wastes will be carried to permanent dumping ground. The floating debris will be cleared. All the trees will either be cut or transplanted outside the reservoir area. The residual stumps should not exceed 0.3m above the ground surface. b. Construction of Ertanggou Reservoir In the operation period, it is predicted that the water surface of Etanggou Reservoir will be 0.9 km 2 . The inundation will involve in varieties of houses, auxiliary structures, tombs, trees, Page 67 65 special structures and other on-the-ground structures. In order to prevent the reservoir and its water from impacts of the said items, it is necessary to clear up the reservoir bed. The concrete measures will include: Clearance for Health and Epidemic Prevention The clearance for health and epidemic prevention will be done under the technical guidance of the local sector of health and epidemic prevention. There are 16 sets of manure pits in the inundation-impacted area. After the dirt is removed outside the reservoir area, the pits will be disinfected with lime (1 kg/pit) and backfilled with soil. There are 3240.8m 2 of livestock stables in the inundation-impacted area. The method to clearance is the same as for the manure pits above. There are altogether 99 sets of tombs (including 20 ancient tombs) to be removed outside the reservoir area. Of the above, all the tombs younger than 15 years will be removed, the tombs older than 15 years will be managed in accordance with the local culture. After the removal, the tomb pits will be disinfected with chloride of lime (1 kg/pit) and backfilled with soil. Clearance of Trees In the reservoirs area, 167.86 of trees will be clear, including 21.37 mu of fruit plantations and 167.86 mu of other trees, in addition to 958 pieces of scattered trees. Before the reservoir impoundment, all the trees above will either be cut or transplanted outside the reservoir area. The residual stumps should not exceed 0.3m above the ground surface. Clearance of Structures In the reservoir area, 2960.07m 2 of varieties of houses will be demolished and cleared. The height of the remaining part should not exceed 0.5 m above the ground surface. The floatable things will be managed in line of the regulations for health and epidemic prevention. The auxiliary structures include fencing walls, threshing grounds, cellarage, manure pits, livestock stables, water tanks, stoves and ovens. They will be demolished together with the houses. Clearance of Special Structure In the inundation-impacted area, there is a hydrological station. It should be cleared before the reservoir impoundment. c. Alagou Reservoir The scope of Alagou Reservoir bed clearance is the area below the normal water level (940.77m). Clearance for Health and Epidemic Prevention Page 68 66 Domestic garbage and excreta from livestock stables and toilets should be completely cleared. The remaining should be disinfected with chloride of lime (l kg/m 2 ). The treatment of excreta should follow Hygienic Standards for Sanitization of Human Excreta" (GB 7959- 1987). The manure pits and sewage pits should be disinfected with chloride of lime (l kg/m 2 ) and buried. The floor of houses, livestock stables and toilets as well as the walls 2m above ground will be sprayed with 4% supernatant of chloride of lime (0.3 kg/m 2 ). The time of disinfection should be no less than 30 minutes. The above activities of clearance for health and epidemic prevention will be done in the order a resettlement, clearance and demolishment. The floatable things such as leaves, branches and crop residues should be burnt on the site. Demolishment and Clearance of Structures In the demolishment of houses and auxiliary structures, the principle of “disinfection before demolishment” should be followed. Houses and sheds/stables will be demolished manually. The recyclable materials will belong to the owner, and s/he can carry them back home for re- use. The floatable things such as leaves, branches and crop residues should be burnt on the site. The walls should be pushed down and leveled. The water wells (pits), cellarage, shaft sinking and drifting and other underground engineering in the draw-down area of the reservoir will be properly managed on the basis of the geological conditions. Clearance of Trees Before the reservoir impoundment, all the trees above will either be cut or transplanted outside the reservoir area. The residual stumps should not exceed 0.3m above the ground surface. Evaluation of the Measures: Before the impoundment, bed clearance of the 3 reservoirs will be done strictly following the above measures to effectively reduce the contamination possibility against the water quality. 3Management of Air Environment Sensitive Points in the Construction of Meiyaogou Reservoir Dustproof at Roads and During Transportation: Vehicle dust is generated mainly from road surface, road damage and the goods on a running vehicle. It can be reduced when effective control measures are taken. Air pollution should be prevented in the process of transportation. When transporting a dusty material, the material should be properly moistured or covered with canvas. When transporting bulk cement, the tank should be well sealed. When transporting bagged cement, it must be properly covered. In addition, the vehicles should be frequently cleaned. The speed should not exceed 20 km/h when passing by Meiyaogou Village and the living quarters. Damaged road should be timely repaired, and the temporary roads at construction Page 69 67 sites should be covered with pebbles so as to reduce dust. In hot dry period, water spraying 4~6 times a day will be required at sensitive areas. Generally speaking, a diesel engine discharges more tail gas with higher contents of pollutants. Most of the vehicles in the construction are of diesel engine, and it is required to be equipped with tail gas cleaner. Evaluation of Measures : With the above environmental mitigation measures, the impacts of waste gas and dust from the construction on the sensitive target will be reduced to an acceptable level. 4Measures of Noise Control Sensitive Points in the Construction of Meiyaogou Reservoir The engineering time will be properly arranged.

Production Area In accordance with the resettlement action plan, 15.73 ha of farmland will be required for the resettlers due to the construction of Ertanggou Reservoir. It is planned to reclaim 13.07 ha of farmland. Vegetable cultivation will be the main crop, and there will be limited problem of Page 75 73 water-soil loss. At the new production area for resettlement, the following measures of soil conservation will be taken: According to the resettlement action plan, the land reclamation will be: When the slope is between 20°~25°, farmland of sloping terrace will be built, and when the slope is less than 20°, farmland of leveling terrace will be built. Some of the farmland ridges will be protected by dry-laid stone masonry. In addition, irrigation and drainage facilities will be built around. The terraced farmland will be reclaimed along the contour. Small structures such as water interception trench, water retaining pool and drainage channel will be constructed for water harvest and soil conservation. Contour cultivation and intercropping will be the major patterns in the agricultural production in the resettlement zone. Then, the vegetation coverage and duration will be enlarged together with soil conservation. b. Living Quarter The living quarter for the resettlers will be 2.67 ha. It will be composed of the facilities of residential houses, school, roads and other infrastructures. Problems in soil conservation will take place mainly during the period of land leveling. According to the resettlement action plan, the measures of soil conservation here will include the construction of masonry retaining walls, slope protection, drainage channels and so on. Construction of Alagou Reservoir The project construction will be done in 6 sections. They are dam construction site, material excavation site, material stacking ground, road building site, temporary engineering site and living quarter and special structure construction site. The measures will include engineering measures, biological measures and temporary measures. A. Salient works area a. Salient structure During the process of dam filling, there will be a cofferdam on the upper side but no retaining structure on the lower side, so a retaining wall needs to be built at the dam toe on the downstream side to prevent mud and stone from entering to the lower river channel in construction. The retaining wall will be of masonry gravity wall with a length of 450m, a crest width of 0.5m, a height of 1.0m, a slope ratio of 1:0.3, and a foundation depth of 0.5m, and it requires 146m 3 of earth cut and 517 m 3 of grouted rubble. b. Reservoir management station Prior to the construction the management station, the topsoil in this area will be stripped and placed at a corner in a concentrated way. It will be retained by sacked earth and covered with color striped fabric in case of strong wind or rainstorm. When the station is built, make green the open spaces, backfill the land with topsoil and level it, plant bushes sacsaoul, Calligonum and seeds of Astragalus Adsurgens Pall, and furnish a complete set of irrigation system. Topsoil stripping and backfill amounts to 150mm 3 , and the area to be retained with sacked earth is 50m long. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m Page 76 74 high, and 1:0.5 in slope ratio and require 43m 3 of sacked earth. The area to be greened is 0.05hm 2 , which will be planted with 140 sacsaouls, 140 Calligonums, and sown with 2.5kg of Astragalus Adsurgens Pall seeds. c. Access to reservoir The accesses from the reservoir area to outside include a 2km-long road from the reservoir to the reservoir management area and a 4km-long road from the reservoir management area to Nanshan mining area. Both are of Grade 3. The roadbed will be prepared through excavation and filling, and the latter will be the major part. To prevent loss of soil and water during the roadbed construction, it’s planned to use sacked earth for retaining on both sides of the filled roadbed with a retaining length of 7200m. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio and require 5400m 3 of sacked earth. B. Quarry area Although the quarry upstream of the dam for dam fill materials will be inundated at reservoir impoundment, it should be excavated at a stable slope to avoid landslide caused by watering. The project spoil will be treated combined with the use of the quarry upstream of the dam. Since the amount of the excavated materials is far more than that of the spoil, the excavated pit will be big enough to accommodate the spoil. The quarry will be excavated by zone. After one zone is exploited, it will be backfilled with spoil in time, and then the spoil will be spread and leveled. The surface of the filled spoil will be covered with derrick stone collected from the shoal in two layers, the lower one with stone of about 100mm in diameter and the upper one with stone of about 200mm in diameter. The spoil surface to be treated totals 5.5hm 2 . As for the quarry downstream of the dam, to prevent water flow from scouring the excavated slopes and the consequent landslide and collapse of the banks, masonry slope protection is proposed for the excavation slopes of the section that may suffer scouring. Meanwhile, river dredging should be conducted to smooth the water flow. The section to be protected is 1500m long with a slope ratio of 1:3 and a protection thickness of 0.3m and requires 5985m 3 of grouted rubble. The quarry for aggregate is at Yu’ergou Gobi. To prevent loss of soil and water on the mining surface, under which a retaining ridge will be build before exploitation, and the rock will be piled within the ridge. The ridge will be built with sacked earth, 300m long, 0.75m wide on the top, 0.75m high and 1:0.5 in slope ratio, and require 255m 3 of sacked earth. After the exploitation, the excavation slash will be treated. The land will be leveled first, and then be covered with derrick stone collected nearby in two layers, the lower one with stone of about 100mm in diameter and the upper one with stone of about 200mm in diameter. The slash to be treated totals 2.85hm 2 . C. Storage area The temporary storage area is located at the left-bank alluvial plain 1km downstream of the damsite. To prevent loss of soil and water, sacked earth will be piled around the area prior to material storage for the purpose of retaining. The piled sacked earth will extend 720m long with a sectional size same as that of the salient works area and require 540m 3 of sacked earth. The stored materials will be covered with color striped fabric in construction in case of strong wind or rainstorm. The color striped fabric demand is 25500m 2 . When the stored materials are used up, the storage slash should be treated through covering it with derrick stone collected nearby in two layers, the lower one with stone of about 100mm in diameter Page 77 75 and the upper one with stone of about 200mm in diameter. The slash to be treated totals 2.4hm 2 . D. Construction access area Sacked earth will be arranged on both sides of the access during the construction period to avoid soil loss in roadbed construction and operation. The sacked earth block will be 5140m long in total with a sectional size same as that of the salient works area. When the construction is completed, the access will be demolished, and the area being occupied will be leveled and treated through covering it with derrick stone in two layers, the lower one with stone of about 100mm in diameter and the upper one with stone of about 200mm in diameter. The area to be treated totals 1.8hm 2 . E. Production and living quarter in construction The production and living quarter in construction is situated at the foot of the mountain and is 2km downstream of the dam, covering 1.07hm 2 . Temporary protective measures should be taken during the construction to prevent loss of soil, and the construction slash should be treated after the completion of construction. The temporary protective measures in construction are: to pile sacked earth into a retaining ridge around the construction area for 425m in total with a sectional area same as that of the salient works area; and to treat the construction slash when the construction is completed, i.e., to cover the ground surface being leveled with derrick stone collected nearby in two layers, the lower one with stone of about 100mm in diameter and the upper one with stone of about 200mm in diameter. The area to be treated totals 1.07hm 2 . F. Special facilities reconstruction area a. Relocation area for hydrometric station Alagou Hydrometric Station will be inundated in the reservoir area, so it’s planned to select a site on the upstream to rebuild a hydrometric station. The relocation area will occupy 1.53hm 2 of Gobi barren land. The planned water and soil conservation approach is as follows: the topsoil in the area will be stripped prior to the construction with an amount up to the demand of vegetation and be placed at a corner in a concentrated way. It will be retained by sacked earth around and covered with color striped fabric in case of strong wind or rainstorm. Since there are many strong wind days in the local area, it’s proposed to temporarily cover the disturbed ground surface with color striped fabric until the end of the construction so as to avoid loss of soil and water due to wind erosion. When the hydrometric station is built, make green the open spaces, backfill the land with topsoil and level it, plant bushes sacsaoul, Calligonum and seeds of Astragalus Adsurgens Pall, and furnish a complete set of irrigation system. As for the relocation area for hydrometric station, topsoil stripping and backfill amounts to 1350mm 3 , and the area to be retained with sacked earth is 150m long. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio and require 112m 3 of sacked earth. The color striped fabric demand is 2200m 2 . The area to be greened is 0.45hm 2 , which will be planted with 1260 sacsaouls, 1260 Calligonums, and sown with 22.5kg of Astragalus Adsurgens Pall seeds. Page 78 76 b. Power line reconstruction area 3km of 220kV power line needs to be reestablished at other place for the project, and the construction will disturb the ground surface and result in loss of soil and water. The reconstruction area will occupy 0.16hm 2 of land. It’s planned to temporarily cover the area with color striped fabric in construction and to treat the area by covering it with derrick stone after construction. The color striped fabric demand is 220 m 2 , and the slash to be treated is 0.16hm 2 . c. Water supply pipe line reconstruction area 2.0km of water supply pipe line needs to be reestablished for the project, and that will occupy 0.82 hm 2 of land, of which 0.63hm 2 is Gobi desert and 0.19hm 2 is dry land. The backfill earth will be piled on one side of the pipe temporarily during the excavation period, retained by sacked earth and covered with color striped fabric. The time for temporary piling of the earth rock should be minimized in construction, and the construction should avoid strong wind or raining days as far as possible. When the pipes are installed, the occupied area will be covered with rock block. The land to be treated totals 0.82 hm 2 , and the sacked earth retaining ridge will be 550m long, 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio, and require 468m 3 of sacked earth. The color striped fabric demand is 650m 2 . d. Communication line reconstruction area 4km of communication line needs to be reestablished at other place for the project, and the reconstruction area will occupy 1.15hm 2 of land. The prevention measures proposed are the same as those for the power line reconstruction area, and the main measures are to temporarily cover the area with color striped fabric in construction and to treat the area by covering it with derrick stone after construction. The color striped fabric demand is 450 m 2 , and the slash to be treated is 1.15hm 2 . e. Simple road reconstruction area 6.5km simple road needs to be reconstructed, and that will occupy 8.45 hm 2 of land, of which 5.98hm 2 is Gobi desert and 2.47hm 2 is dry land. The roadbed will be prepared through excavation and filling, and the latter will be the major part. To prevent loss of soil and water during the roadbed construction, it’s planned to use sacked earth for retaining on both sides of the filled roadbed with a retaining length of 13,000m. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio and require 11050m 3 of sacked earth. Evaluation on the measures: The above measures to control soil and water erosion can significantly reduce the loss of soil and water for the three reservoirs during the project construction period and natural restoration period. In addition, the planting measure can increase the greening area in the project area, and that will play a certain role in improving the regional environment. 4.2.1.3 Mitigation measures during operation period 4.2.1.3.1 General measures Page 79 77 (1) Domestic sewage treatment measures; (2) Solid waste treatment measures; (3) Ecological environment protective measures - measures to prevent drying up of the lower watercourse; Specific measures to be taken for the three reservoirs in regard to the above three aspects are presented in Section 4.2.1.3.2. (4) Measures to prevent dam failure risk during operation period To prevent dam failure risk, the emergency measures for the three reservoirs are: internal emergency measures, emphasizing on the measures for the dams; external emergency measures, emphasizing on the protective facilities for the safety downstream of the dam and remedy measures. Internal emergency measures A. To take urgent measures to lower the water level of the reservoir, for example, to open the spillway, flood release tunnel and other water discharge facilities. B. To immediately evacuate the construction and management personnel on the dam and in the adjacent areas to ensure the personal safety of the staff. External emergency measures A. To analyze the range of inundation of the lower reaches by GIS and other information technologies, and to determine the impact range of dam failure based on the analysis results. B. To inform the local government of the area downstream of the dam about the accident, evacuate the residents possibly impacted, and minimize the personal and property dangers to the residents caused by dam failure. C. To clarify the quantity, position, and performance of emergency supplies and initiate the distribution and receiving procedures. D. To ensure the accesses in the plant area and to outside are unimpeded. E. To initiate the communication, transportation and other systems that can be used when the accident occurs. Evaluation on the measures: The above measures can minimize the losses of dam failure. 4.2.1.3.2 Special measures (1) Domestic sewage treatment measures Meiyaogou Reservoir Meiyaogou Reservoir is staffed with 6 front-line persons. If they work in two shifts, there will be 3 front-line operators constantly, plus 4 management personnel, then the sewage Page 80 78 discharge will be 0.6t per day based on a per capita sewage discharge of 85L per day, and the annual sewage discharge will be up to 217t. WSZ underground complete sewage treatment equipment is proposed to treat this part of sewage. It has a sewage treatment capacity of 1m 3 /h, which can meet the demand of domestic sewage treatment for the management area. After being treated, the domestic sewage can be used to water the grasses and plants in the area and the trees along the permanent road in summer and be discharged to the desert and Gobi far away from the river course in winter. Ertanggou Reservoir WSZ underground complete sewage treatment equipment is proposed to treat the sewage produced by the reservoir operators and management personnel during the operation period. It has a sewage treatment capacity of 1m 3 /h, which can meet the demand of domestic sewage treatment for the management area. After being treated, the domestic sewage can be used to water the grasses and plants in the area and the trees along the permanent road in summer and be discharged to the desert and Gobi far away from the river course in winter. Alagou Reservoir Alagou Reservoir is staffed with 16 persons during the operation period who will produce 4 tons of sewage per day. The domestic sewage from the reservoir management area will be collected and drained to a septic tank via pipe. The 10-40B10 septic tank built during the construction period can be used, but vehicles cannot pass over it. Due to the small flow of the Alagou River on the downstream of the reservoir, direct discharge of sewage to the river will pollute the lower reaches to a cer tain extent. It’s required that the treated domestic sewage be collected through an impervious tank. The impervious tank will utilize the facilities built during the construction period and will collect the outflow from the septic tank. The water can be used for plant watering in the management area or evaporate naturally and will not be discharged directly to the water body. Evaluation on the measures: The above domestic sewage treatment measures can ensure the sewage treatment up to the standard 100%, and the comprehensive utilization of the treated water can permanently and effectively avoid the pollution of domestic sewage to the river water. (2) Solid waste treatment measures Meiyaogou Reservoir, Ertanggou Reservoir 3 garbage collectors will be furnished in the management and living quarters of Meiyaogou Reservoir and Ertanggou Reservoir respectively to collect the domestic garbage in a concentrated way. The garbage will be cleared regularly each week and be transported to and filled in the solid waste landfill of Tuokexun County so as to prevent it from entering the reservoir area and polluting the water body. Alagou Reservoir 4 garbage collectors will be furnished in the management and living quarters of Alagou Reservoir to collect the domestic garbage in a concentrated way. The garbage will be cleared Page 81 79 regularly each week and be transported to and filled in the solid waste landfill of Tuokexun County so as to prevent it from entering the reservoir area and polluting the water body. Evaluation on the measures: The above domestic garbage treatment measures can ensure a garbage treatment rate of 100% and can effectively protect the living environment of the management area. (3) Ecological environment protective measures - measures to prevent drying up of the lower watercourse To carry out the essentials of the Circular on Strengthening Environmental Protection in Hydropower Development (HuanFa [2005] No. 13) jointly issued by the former General Administration of Environmental Protection of China and the National Development and Reform Commission, dehydration of the lower watercourse and increment of drying-up extent of the watercourse should be avoided so as to reduce the impact on water environment and aquatic ecology. Meiyaogou Reservoir Currently Meiyaogou River course is basically drying up when water is diverted from the headwork of Renmin canal; in addition, there is no ecological flow demand for the watercourse downstream of the Meiyaogou Reservoir dam. Therefore, the reservoir will not discharge water to the lower watercourse during the operation period. Ertanggou Reservoir According to the design of main works, a 500mm-diameter glass fiber reinforced plastic pipe extending from the access to the dam to the riverbed downstream of the dam is proposed at the outlet of irrigation water outlet to discharge ecological base flow. The discharge is required to be not less than 10% of the long-term average flow at the damsite section, i.e., 0.25 m 3 /s. Alagou Reservoir A small-sized siphon pipe will be installed at the damsite to discharge ecological base flow not less than 0.4 m 3 /s. Evaluation on the measures: The discharge measures for ecological base flow can ensure no increment in drying up section of the Ertanggou and Alagou rivers during the operation period of the works. (4) Resettlement Among the three proposed reservoirs, only Ertanggou Reservoir involves resettlement. To solve the problem of poor soil quality of farmland in the host area for Ertanggou Reservoir, it’s required to mellow the soil of farmland in the host area to ensure the quality of the farmland not inferior to that of the original farmland. Page 82 80 Summary of General Mitigation Measures against Environmental Impacts of Reservoir Works Table 4.2-10 Typ e Perio d EI Factor Mitigation Measures Enforcem ent Unit Supervision Unit Monitorin g Unit D e s i g n s t a g e During the design stage of the three reservoirs, the environmental protection requirements have been considered as far as possible in the selection of damsite, quarry, and dumping area, construction planning and other aspects so as to obtain the maximum project benefit with the minimum disturbance and environmental change. In the preparation of the environmental impact report, the second time of public participation will be involved to solicit the comments and suggestions from the people that may be impacted in the project construction so as to further improve the design of main works and environmental protection measures. Meanwhile, the public comments and suggestions will be reported to the relevant authorities and monitoring departments, and the solutions will be publicized. Designer, Environm ent workgroup Environment al managemen t offices of Turpan City, Shanshan County, and Tuokexun County — Water environm ent Use of conventional explosive in construction will greatly influence water quality, so it’s suggested to use emulsified explosive, water gel explosive and other environmental friendly explosives to mitigate the impact of explosives on water quality. In line with the requirements of “three simultaneousness”, the Owner should include the construction and effective operation of waste water treatment station as an article of the Project Contract to ensure its effective operation. Project environmental management department should oversee and inspect the construction site regularly, find out the production waste water treatment status, and put forward the corrective comments on harmful situations orally and in written. Reservoir bottom clearance measures. R e s e r v o i r C o n s t r u c t i o n p e r i o d A m b i e n t a i r Dust The dam construction area and material piling area where there is quite a lot of excavation, the measure of sprinkling will be taken on days without rain (mainly for the places of excavation, dumping and loading) to speed up the dust settlement and lessen the time and scope of dust impact. The times of sprinkling and water demand will be determined according to the weather and dust yield. The neighboring areas of the processing system will be supplemented with dust reduction through sprinkling to lessen the time and scope of dust impact. Air contamination should be prevented during the material transportation process. The dusty materials should be wetted properly or covered with canvas tarpaulin. The tanks of vehicles to transport bulk cement should be in good sealed status, and the bagged cement should be covered and closed in transport. The transportation vehicles should be often cleaned. The pavement damaged by vehicles should be repaired in time, and the temporary construction road should be paved with gravel to reduce the dust caused by poor road conditions. Sprinkling trucks should be arranged in the construction area to sprinkle the excavation area, material piling area, construction road and other places with much dust on the days without rain. The dumping area should be sprinkled regularly to control dust, and the times of sprinkling will be determined according to the actual dust yield. In the light of the relevant regulation on labor protection of China, the construction personnel on the site must be provided with dust proof mask and other protective articles for labor protection.

To implement the Standard of Vehicles Scrappage, carry out the system of mandatory renovation and scraping, and duly replace the old vehicles whose engines have high gas consumption and low efficiency and the tail gas emission seriously exceeds the standard. Enhance the maintenance of the machinery equipment using fuel oil so as to keep the engines in normal and good service condition. In the section of tunneling by drilling and blasting, ventilation and dust removal measures will be considered in construction. The installation of axial flow ventilators and air purifiers can significantly improve the air quality. Acoustic environm ent Distribute earplugs, earflaps, anti-noise cotton, anti-noise helmet and other personal protection articles, and choose the most proper protection articles according to the post. Strengthen road curing and vehicle maintenance so as to reduce noise source. Vehicles in service must conform to the Limits of Noise Emitted by Stationary Road Vehicles (GB16170-1996) and Allowable Noise Limits for Motor vehicle (GB1495-79), and low-noise vehicles should be used as far as possible. Use anti-vibration mounting for equipment vibrating greatly. Domestic garbage Arrange movable garbage collectors and garbage cans in the temporary living quarters, often spray pesticide at the garbage collecting station to avoid unfavorable impact on the living and health of the construction personnel due to breeding of mosquitoes and flies. Furnish refuse trucks to deliver domestic garbage to the wasteyard closest to the project area, and treat the garbage by filling. Do a good job in sanitation propaganda to the construction personnel and make them get used to put garbage in the garbage collector. Ecologica l environm ent Protection of terrestrial plants Identify the scope of area for construction and forbid the construction personnel and vehicles to enter into the non-construction area. When the construction is completed, the temporary production and living facilities will be removed, and these areas, quarry, and other construction slashes will be leveled to facilitate the recovery of vegetation under natural status. Protection of terrestrial animals: A. Strengthen propaganda and education of the ecological protection in forms of brochure and sign plates to the construction personnel and residents around, and restrict the construction personnel to hunt the local wild animals illegally and eat birds and beasts to mitigate the impact of construction of the local terrestrial animals. B. Set up a punishment system for ecological destroying, forbid the construction personnel to hunt wild animals illegally or to eat birds and beasts; identify the scope of construction area according to the general construction layout, establish stakes and boundaries, construction personnel and vehicles to enter into the non-construction area; forbid smoking and firing in the non- construction area, and prohibit the construction personnel to use fire in the field. C. Most of the wild birds and beasts go out to find food in morning and evening, and the birds rest at the noon time. To reduce disturbance of blasting and construction noise to wild animals, blasting method, quantity and time should be planned well, and blasting in the morning, evening and noon should be minimized. D. Reinforce the environmental protection, supervision and management for the project construction, establish environmental protection and monitoring organization and specific environmental protection personnel, strengthen environmental protection education to the construction personnel, forbid them to hunt wild animals, and handle the illegal activities by law.

The wastewater of aggregate processing plant will flow from sand washer to wastewater regulation tank, and then the wastewater with high content of suspended solid will be pumped to fine sand recovery and treatment machine. That can recover about 80% of fine sand greater than 0.035mm. The filtered water will be subject to primary sedimentation in grit tank, and the clear liquid on the top will be added with flocculant and flow to sedimentation tank for secondary sedimentation. The top clear liquid subject to flocculating sedimentation can be used for watering of the construction site for dust reduction, vegetation irrigation, and so on. A rectangular tank will be built at the confluence of oily wastewater for machinery washing, and at its inlet oil-separating materials will be furnished. The oily wastewater will flow through the materials to the tank by gravity, and the floating oil will be recovered when the tank is full. After 12 hours the water will be drained to water storage tank and may be used for water spraying to reduce dust. The treatment structure is simple and free of maintenance of mechanical equipment. During the operation, the operator only needs to regularly clean and replace the oil-separating materials, clean the tanks, and recover the floating oil on time. After the construction, the bottom of the treatment tanks will be cleared with the waste residue being transformed to solid waste landfill. The treatment tanks will be filled with earth after clearance. Wastewater from concrete batching system will be mainly spread on the ground surface in flake, and the cement slurry will be condensed after water evaporation and seepage and harden the ground surface. It needs to be moved after the construction.

The daily sewage discharge of the construction area of Meiyaogou Reservoir works is 49m 3 /d, the sewage receiving tank for the temporary living quarter is designed to accommodate 5 days of sewage discharge, so its design sewage receiving capacity is 250m 3 . The design size of the septic tank is: L×W×D=15m×10m×2m. Latrine of brick and concrete structure is arranged in the temporary living quarter, and it’s considered to use grouted rubble for seepage control. Only feces drying tank is considered, and the feces treated will be used as manure. The latrine unnecessary after the construction will be cleared, disinfected and embedded. Environmental friendly lavatories will be built based on the number of people and the inhabitation density of the construction areas of the main works and for other works. The lavatories are simple and easy to remove, and their location can be adjusted according the need of the construction personnel. Rot of plants in reservoir area and others The construction of geomembrane requires the removal of building in the reservoir area, felling of trees, and clearance of floating matters. As for the removal of buildings, the walls will be pushed over and leveled with bulldozer, and the garbage be transported to the permanent dumping area. The matters easy to float in the reservoir will be cleared manually, and all the trees will be cut down and transported out of the reservoir area or be moved outside. The trees should be cut flush with the ground surface with the studs left over not more than 0.3m over the ground surface. The remaining branches, withered trees and other floating matters will be transported outside the reservoir area.

The design of the salient works has considered such measures as slope protection for the upstream and downstream slopes of the dam, energy dissipation and anti- scouring for the spillway and diversion and flood release tunnel, rock surface for the excavation slopes on both ends of the dam, and all slopes being excavated at stable slope ratio. b. Temporary measures: Construction in strong wind day or raining day will be minimized. During the construction, masonry retaining wall is required at the lower dam toe in dam filling to avoid the earth and rock from entering the downstream river reaches and the soil erosion. It’s forbidden to excavate, pile materials and harden the ground at discretion to minimize damage to the original ground. Reasonable measures will be taken to protect the soil and water resources. The excavated earth should be utilized as far as possible, and temporary protection treatment should be conducted in piling prior to the utilization. Effective measures will be taken to control and prevent landslide and other soil erosion disasters caused by construction. The area will be cleared after the construction. The retaining wall will be of masonry gravity wall a crest width of 0.5m, a height of 1.0m, a slope ratio of 1:0.3, and a foundation depth of 0.5m. Access area: The temporary construction roads mainly consist of the temporary roads between the damsite and the quarries and those between the reservoir structures. The measures for soil and water conservation are: to make watering and dust prevention treatment in construction and to reduce loss of soil and water in operation. The area occupied should be leveled after the completion of construction. Quarry area: Excavate the quarries in non-flood season. The excavated materials can be directly piled on the side for flood passing to play a role of flood prevention and release. The quarries should be excavated by zone. When the upper quarry is excavated, the excavation slash should be leveled. Although it will be inundated at reservoir impoundment, it should be excavated at a stable slope. A sacked earth residue retaining ridge will be built below the excavation surface prior to the excavation of the left-bank quarry, which will be treated after the excavated and be covered with cobble and gravel. The quarry for concrete aggregate is in the shoal of the upper river course. A residue retaining ridge will be built below the excavation surface prior to excavation, and the rock materials will be concentratedly piled within the ridge. The excavation slash will be leveled after the excavation, and it will be inundated at reservoir impoundment. The ridge will have a crest width of 0.75m, a height of 0.75m, and a slope ratio of 1:0.5. Transmission line area: During the construction of permanent transmission line area, exposing of the excavated materials should be minimized, and the materials can be covered with color striped fabric. The land occupied will be treated after the construction. Production and living quarter in construction: It includes the land temporarily occupied for production and living. The temporary production areas cover the areas for concrete batching, rebar processing and timber processing. The temporary living quarter s cover dormitory and work shed. Temporary production and living quarter will be watered for moisture proof in construction so as to reduce the dust. The land temporarily occupied will be leveled and covered with cobble and gravel after construction.

The main structures are grit tank, sludge drying bed, and construction water tank. Two simple 12m×10m×3m (L×W×H) sedimentation tanks will be excavated between the aggregate processing zone and the concrete batching zone. After sedimentation in the tanks for 1.5 hours, the wastewater with sand can meet the discharge requirements. Sludge will be transformed away in time according to its amount by 5-10t truck. A rectangular sedimentation tank and water storage tank will be built at the confluence of oily wastewater for machinery washing, and at the inlet of the sedimentation tank oil-separating materials will be furnished. The oily wastewater will flow through the materials to the tank by gravity, and the floating oil will be recovered when the tank is full. The water treated will be used for water spraying to reduce dust. After the construction, the bottom of the treatment tanks will be cleared with the waste residue being transformed to solid waste landfill. The treatment tanks will be filled with earth after clearance. The size of the sedimentation tank: L×W×D=4.0m×2m×2.3m (freeboard 0.3m), and that of the water storage tank is: L×W×H = 2.5m×2m×2m. Wastewater from concrete batching system will be mainly spread on the ground surface in flake, and the cement slurry will be condensed after water evaporation and seepage and harden the ground surface. It needs to be moved after the construction. Tuokexun County Alagou Reservoir Domestic sewage The domestic sewage treatment equipment is arranged close to the temporary living quarter.

The management and office area will produce less garbage, so it’s suggested to arrange 10 garbage cans to collect garbage. 1 refuse truck will be furnished to deliver the domestic garbage to Tuokexun County wasteyard and treat it by filling. Constructor Xinjiang Environmental Protection Department, Turpan Prefecture Environmental Protection Bureau, Tuokexun County Environmental Protection Bureau Page 91 89 Location Description EI Factor Mitigation Measures Enforcement Unit Supervision Unit Monitoring Unit Soil and water conservation Salient works area A. Salient structure: During the process of dam filling, there will be a cofferdam on the upper side but no retaining structure on the lower side, so a retaining wall needs to be built at the dam toe on the downstream side to prevent mud and stone from entering to the lower river channel in construction. The retaining wall will be of masonry gravity wall with a length of 450m, a crest width of 0.5m, a height of 1.0m, a slope ratio of 1:0.3, and a foundation depth of 0.5m, and it requires 146m 3 of earth cut and 517 m 3 of grouted rubble. B. Reservoir management station: Prior to the construction the management station, the topsoil in this area will be stripped and placed at a corner in a concentrated way. It will be retained by sacked earth and covered with color striped fabric in case of strong wind or rainstorm. When the station is built, make green the open spaces, backfill the land with topsoil and level it, plant bushes sacsaoul, Calligonum and seeds of Astragalus Adsurgens Pall, and furnish a complete set of irrigation system. Topsoil stripping and backfill amounts to 150mm 3 , and the area to be retained with sacked earth is 50m long. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio and require 43m 3 of sacked earth. C. Access to reservoir: The accesses from the reservoir area to outside include a 2km-long road from the reservoir to the reservoir management area and a 4km-long road from the reservoir management area to Nanshan mining area. Both are of Grade 3. The roadbed will be prepared through excavation and filling, and the latter will be the major part. To prevent loss of soil and water during the roadbed construction, it’s planned to use sacked earth for retaining on both sides of the filled roadbed with a retaining length of 7200m. The sacked earth retaining ridge will be 0.75m wide on the top, 0.75m high, and 1:0.5 in slope ratio and require 5400m 3 of sacked earth. Quarry area: Although the quarry upstream of the dam for dam fill materials will be inundated at reservoir impoundment, it should be excavated at a stable slope to avoid landslide caused by watering. The project spoil will be treated combined with the use of the quarry upstream of the dam. Since the amount of the excavated materials is far more than that of the spoil, the excavated pit will be big enough to accommodate the spoil. The quarry will be excavated by zone. After one zone is exploited, it will be backfilled with spoil in time, and then the spoil will be spread and leveled. The surface of the filled spoil will be covered with derrick stone collected from the shoal in two layers, the lower one with stone of about 100mm in diameter and the upper one with stone of about 200mm in diameter. The spoil surface to be treated totals 5.5hm 2 . As for the quarry downstream of the dam, to prevent water flow from scouring the excavated slopes and the consequent landslide and collapse of the banks, masonry slope protection is proposed for the excavation slopes of the section that may suffer scouring. Meanwhile, river dredging should be conducted to smooth the water flow. The section to be protected is 1500m long with a slope ratio of 1:3 and a protection thickness of 0.3m and requires 5985m 3 of grouted rubble. The quarry for aggregate is at Yu’ergou Gobi. To prevent loss of soil and water on the mining surface, under which a retaining ridge will be build before exploitation, and the rock will be piled within the ridge. The ridge will be built with sacked earth, 300m long, 0.75m wide on the top, 0.75m high and 1:0.5 in slope ratio, and require 255m 3 of sacked earth. After the exploitation, the excavation slash will be treated.

In the design, the temporary dumping areas for the construction period and the permanent dumping areas after the construction should be arranged reasonably based on the specific conditions of various canal sections, and flood-control tailing hold works and sewage-control tailing hold works should be arranged to control the spoil in a concentrated way and minimize the impact of spoil piling on environment. Soil and water conservation plan should be prepared well. The general layout should fully consider not only the type, mode and impacting degree of soil erosion and water loss caused by the project construction, but also the master plan of the management area for the operation period of the project. Great attention should be attached in design on the public health during the construction period. The dwelling conditions in the temporary living quarter should not be too simple, crude and crowded, and the area with good surroundings should be selected as the living quarter for the construction personnel to prevent the introduction and spreading of epidemic diseases. The construction of the works will cause great noise, so the designer should take reasonable sound insulation and noise reduction measures as required so as to mitigate the impact of construction noise on site construction personnel. Find out the opinions and comments on environmental problems and impacts of the public and all walks of life to be impacted through public participation before, during and after the project development so as to improve the design. 4.2.2.2 Mitigation measures at construction stage Since the canal building (rehabilitation) works have similar construction items but different surrounding characteristics, their mitigation measures have commonness and differences. The section elaborate the general measures applicable to all works and the special countermeasures for each specific works (unless otherwise specified, the measures mentioned hereinafter will be general measures). (1) Water environment Production wastewater General measures: Production wastewater will be mainly from concrete batching and curing and cleaning and maintenance of transport vehicles and other machinery. Since the construction sites are dispersed, the wastewater from concrete batching and curing is difficult to collect and will be fully consumed through evaporation. Only minor repair and Page 99 97 maintenance will be conducted for the mechanical equipment at the site, so the production wastewater is mainly from washing of the batching system which is small in quantity and will be fully consumed through natural evaporation and seepage. Therefore, no mitigation measure will be taken for the production wastewater. Special measures: Alagou Main Diversion Canal Works will have one concrete aggregate quarry area located on the riverbed 1.0km downstream of the maintain outlet of the Alagou River. The concrete aggregate will be screened on the spot. One desilting tank will be built in the concrete aggregate quarry area with a capacity of 60m 3 and a size of 10m ´ 3m ´ 2m (L ´ W ´ D), designed to accommodate 3-day wastewater discharge. The wastewater will be collected in the temporary desilting tank, and be used for watering the construction access and spoil to reduce dust after deposition. Finally the desilting tank will be removed and transported to the permanent dumping area, and the spot will be backfilled with the excavated earth or stone. Domestic sewage Special measures: A. Taerlang Branch Canal Works In accordance with the construction production layout and due to the short construction period of the project, limited domestic sewage discharge and strong evaporation in the project area, it’s decided that the domestic sewage will be collected in the temporary sewage receiving tank and be consumed through natural evaporation and seepage. Five tanks are arranged, one for each living quarter. The tank is designed to accommodate 2-day sewage discharge and will have a design capacity of 25.5m 3 and a size of 4m ´ 2.8m ´ 2.5m (L ´ W ´ D). Five latrines of brick and concrete structure with a floor area of 6m 2 will be built, one in each living quarter. After the construction, the sewage receiving tanks and latrines will be cleared, disinfected and buried. B. Alagou Main Diversion Canal Works The temporary production and living quarter is located in gravel desert, where the mean annual evaporation is up to 3744mm. The domestic sewage can be collected in the temporary sewage receiving tank and evaporate naturally. The daily sewage discharge will be 10.1m 3 /d in the construction quarter during peak period, and a sewage receiving tank will be built in the temporary production and living quarter. The tank is designed to accommodate 2-day sewage discharge and will have a design capacity of 20.2m 3 and a size of 5m ´ 2m ´ 2m (L ´ W ´ D) to facilitate design and construction. Meanwhile, one environmental friendly lavatory with a floor area of 20m 2 will be provided in the temporary production and living quarter, and one simple lavatory with floor area of 6m 2 be provided in the concentrated construction site. Feces from the lavatories will be used as manure after being disinfected with lime. When the project is completed, the sewage receiving tanks and lavatories will be dismantled, be backfilled with the excavated earth after the concrete and gravel being delivered to the permanent dumping area, and be leveled and compacted. C. Ertang Branch Canal Seepage Control Upgrading Works Page 100 98 The construction personnel for Ertang Branch Canal Seepage Control Upgrading Works will stay in the residential area nearby, so the domestic sewage produced will be collected and treated in a unified way in the residential area, no additional treatment measure will be taken. Evaluation on the measures: The above measures can effectively mitigate the adverse environmental impact of domestic sewage in the construction period. (2) Ambient air Specific measures: Operators for the batching plant will be protected for health care, for example, wearing gauze masks and wind glasses; Cement, lime and other powder materials should be canned or bagged. Transportation in bulk is forbidden so as to prevent dust along the transportation route; Cover the piled materials with tarpaulin in rain and strong wind days; Strictly regulate the traveling route of the transportation machinery during the construction period; Often sprinkle water for curing during the construction period to reduce dust. Water 2-3 times per day or more often in strong wind event; Avoid earth excavation under strong wind weather. Evaluation on the measures: The above measures can minimize the impact of atmospheric environment contamination on the construction personnel during the construction period. (3) Acoustic environment Specific measures: In accordance with the Noise Limits for Construction Site (GB12523-90), the working hours of the people working at the screening system, batching system and other highly noisy environment should be controlled as per the labor protection regulations and be offered with anti-noise articles. Use low-noise equipment as far as possible, and strengthen the maintenance of mechanical equipment. Evaluation on the measures: The above measures can minimize the impact of noise on the construction personnel during the construction period. (4) Solid waste Engineering spoil General measures: Engineering spoil produced in construction is mainly of refused debris and earth. The best solution is to use refused debris and earth as filling materials or backfill Page 101 99 materials on the spot to reduce the amount of waste, and the remaining spoil will be piled at the planned dumping area. Domestic garbage Special measures: A. Taerlang Branch Canal Works a. Provide five movable garbage collectors, one in each temporary construction living quarter, publicize the hygiene knowledge to the construction personnel, and nurture their habit of put garbage in garbage collector. b. Rent one refuse truck every week during the construction period to transport the garbage to the wasteyard belonging to Turpan City Sanitation Bureau. The wasteyard lies at Daqiao Village, Putao Township, Turpan City and is 30km away from the project area in average. B. Alagou Main Diversion Canal Works Domestic garbage will be produced mainly in the temporary living quarter. The domestic garbage yield will be 0.17t daily, and the total domestic garbage yield during the whole construction period will be about 38.8t. One movable garbage collector will be arranged in the temporary production and living quarter, and one temporary garbage collecting tank at each main construction site. The domestic garbage will be cleared once every three days and be transported to Tuokexun County wasteyard. C. Ertang Branch Canal Seepage Control Upgrading Works The construction personnel for Ertang Branch Canal Seepage Control Upgrading Works will stay in the residential area nearby, so the domestic garbage produced will be collected and treated in a unified way in the residential area, no additional treatment measure will be taken. Evaluation on the measures: The above measures can lower the impact of solid waste in construction on the surroundings to a degree within environmental endurance. (5) Ecological environment Specific measures: Strengthen the propaganda of the Environmental Protection Law and the Soil and Water Conservation Law, intensify the construction personnel’s sense of environmental protection, standardize their behavior in construction, and strictly prohibit them from rolling and damaging soil and vegetation at discretion. Strictly designate the traveling route of vehicles and other construction machinery and set warning signs on both sides of the construction access. Evaluation on the measures: The above measures can effectively protect the ecological environment around the project area. (6) Soil and water conservation measures Page 102 100 Special measures: Taerlang Branch Canal Works In accordance with the existing status of soil erosion and water loss in the project area and the analysis on the soil erosion and water loss caused by the project construction, the soil erosion and water loss control area is divided into salient structures area, access road area, dumping area, and temporary production and living quarter according to the general project layout. A. Salient structures area Salient structures area includes canal works area and flood control works area. a. Canal works area The land to be disturbed in canal works area is 60.11hm 2 . The canal works area covers water carrying canal, flood control culvert, and flood discharge aqueduct. When the water carrying canal is built, its water passing section will occupy 7.34hm 2 of land. According to the feasibility study report, first, the canal works area is arranged in a relatively concentrated streamline to avoid excessive dispersing of the production line, occupation of large amount of land resources, and soil and water loss caused by increased ground surface disturbance. Next, since the general relief of the project area is quite gentle, the filling and excavation for land leveling should be done nearby so as to minimize the earthwork and avoid soil and water loss. The progress of the structure crossing canal should coordinate with that of water carrying canal. In the design of the salient works, in-situ concrete slab or grouted rubble lining will be adopted for the flood passing section of the structure crossing canal to increase its anti-scouring capacity. Meanwhile, a 9-12m-long V-shaped diffusion area will be made on the downstream surface to reduce the scouring capacity of flow. In a word, the measures stated in the feasibility study report for the salient structures area conform to the requirements on soil and water conservation. Engineering measures: When the construction of canal works is completed, the loosened deposit higher than the ground surface will be leveled according to the topographic conditions so as to prevent wind erosion on strong wind days. Temporary engineering measures: Construction in strong wind day or raining day will be minimized. During the construction, it’s forbidden to excavate and pile materials at discretion to minimize damage to the original ground. The excavated earth should be utilized as far as possible. The earth temporarily piled needs to be covered with dust-prevention net in strong wind day or raining day. b. Flood control works area The main structure in the flood control works area is flood control diversion dikes arranged along the canal. Each flood control diversion dike is arranged in herringbone, and its downstream side is connected with the flood control culvert or flood discharge aqueduct. The earth to backfill the flood control diversion dike will directly use the excavated earth along the canal, and the dike will occupy 78.52hm 2 of land. According the feasibility study report, it’s required to coordinate the construction progress of flood control diversion dike with that of the water carrying canal, flood control culvert or flood discharge aqueduct, Page 103 101 arrange the works in a relatively concentrated streamline to avoid excessive dispersing of the production line, occupation of large amount of land resources, and soil and water loss caused by increased ground surface disturbance. Additionally, in the design of the salient works, grouted rubble protection will be employed for the water-passing surface of the flood control diversion dike to effectively protect the earth on the water-passing surface from scouring. To sum up, the measures stated in the feasibility study report for the salient structures area conform to the requirements on soil and water conservation. Engineering measures: When the construction in the flood control works area is completed, the loosened deposit higher than the ground surface will be leveled so as to prevent wind erosion on strong wind days. Vegetation measures: No vegetation measure is taken because there is neither water source nor soil suitable for plant growth in the area. B. Access road area The project has very convenient access conditions to the outside, and its onsite access road is a newly built one and is included in the salient structures area. This access road, occupying 13.69hm 2 of land, will be used for construction and as the maintenance road for canal after the completion of the project. According to the feasibility study report, the natural gradient will be adopted for the onsite access road based on the topographic variation. The construction road will be sprinkled with water during the construction period to avoid dust. The salient structures conform to the requirements of soil and water conservation. C. Dumping area In accordance with the general project layout, construction of salient works and construction land leveling, it’s finally decided to locate the dumping area within the herringbone dike in the flood control works area to satisfy the demands of construction, and the dumping area will occupy 11.41hm 2 of land. It is safe, reliable, practical technically, and reasonable economically. In line with the characteristics and procedures of site construction, the large amount of waste earth produced from the cross-section of the canal in construction can be reused for the earth backfill of the diversion dyke. Therefore, some earth needs to be stored temporarily during the construction period. The temporary storage area will be 6.85hm 2 . According to the feasibility study report, this scheme required supplementary design of measures for temporary spoil storage and surface protection for the purpose of soil and water conservation. a. Engineering measures The temporary dumping areas will be located within 2.5m away from each excavation face to pile up the excavated materials from the construction and production in a form of trapezoidal bench. The outer slope will be 1:1.5 with a height around 1.0m. The waste earth will be piled according to its amount and piling mode, and the land it occupies is mostly of Gobi. After the construction, the land surface will be protected through covering with gravel. For the purpose of soil and water conservation, an engineering measure of covering the surface of the piled earth with dust-prevention net temporarily in strong wind days will be adopted. Page 104 102 As for the permanent dumping area, the spoil will be piled in a concentrated way utilizing the specific arrangement of the project area, and the spoil surface will be covered with gravel when the construction is completed so as to reduce wind erosion. b. Temporary engineering measures Construction in strong wind day or raining day will be minimized. During the construction, it’s forbidden to excavate and pile materials at discretion to minimize damage to the original ground. The excavated earth should be utilized as far as possible. The earth temporarily piled needs to be covered with dust-prevention net in strong wind day or raining day. D. Temporary production and living quarter The temporary production and living quarter includes temporary production area and temporary living area. The temporary production area covers the places for concrete batching system, aggregate processing system, equipment repairing workshop, rebar processing workshop, wood workshop, parking lot, construction equipment warehouse, consumption goods warehouse, cement storage, fuel storage, and so on. The temporary living area covers the places for office, dormitory, work shed, temporary piling and transfer areas, and so on and will occupy 0.165hm 2 of land. The temporary production and living quarter will be watered to reduce the dust at the construction site. Since the original ground surface of the temporary production and living quarter is covered with gravel, it will be basically free of wind erosion through treatment after the construction. The engineering measures above mentioned are newly added for soil and water conservation. Alagou Main Diversion Canal Works In accordance with the type of relief and existing status of soil erosion and water loss in the project area and the analysis on the soil erosion and water loss caused by the project construction, the soil erosion and water loss control area is divided into canal works area, flood protection dyke area, construction access area, temporary production and living quarter for construction, quarry area and dumping area. A. Salient structures area (canal works area and flood protection dyke area) a. Engineering measures The excavated materials will be piled in a concentrated way on one side of the excavated section within the managed scope. The earth will be piled in trapezoidal bench. The slope ratio and height for earth piling for the canal are 1:1.5 and not over 1.4m, respectively, and those for the flood-prevention dyke are 1:1 and not over 3.0m, respectively. The temporary spoil piled will be covered with geomembrane during the construction period, and watering and other temporary protective measures will be taken for the disturbed ground surface in the construction area. The slash of temporary dumping area and the construction area will be leveled and covered with gravel. b. Vegetation measures: Not applicable c. Temporary engineering measures Page 105 103 Construction in strong wind day or raining day will be minimized. Temporary earth piling will be made in a concentrated way, sprinkled with during the construction period and covered with geomembrane. B. Construction access area Temporary engineering measures: During the construction period, the temporary construction roads in the project area will be watered frequently on the pavement, and the construction vehicles are prohibited to roll their peripheral land. C. Temporary production and living quarter for construction The temporary production and living quarter includes temporary production area and temporary living area, mainly referring to material piling area, temporary housing, concrete batching plant, storage area, and so on. The quarter will be watered to reduce the dust at the construction site. The pollutants (refuse and fuel) will be cleared or buried after the construction, and the Constructor needs to remove all the surface structures and wastes and transport them to the dumping area. Since the original ground surface of the temporary production and living quarter is covered with gravel, it will be basically free of wind erosion through treatment after the construction. The engineering measures above mentioned are newly added for soil and water conservation. D. Quarry area a. Cobble quarry area Cobble quarry area is in the riverbed, so it’s difficult to take engineering measures and vegetation measures. The collection of cobbles should minimize the disturbance to the riverbed, and it’s required to collect only the cobbles that are on the top of the riverbed and move from the upper reaches in flood season. No exposal of riverbed is the criterion for cobble collection. Since the piling of big cobbles on the riverbed can play a role of anti- scouring to some extent, attention should be paid on the protection of riverbed in cobble collection. b. Concrete aggregate quarry area Engineering measures: As for the concrete aggregate quarry area, it’s proposed to backfill the quarrying pit of the quarry with the nearby discards from the screening after the construction of the salient works, and level and compact the pit mechanically. E. Dumping area The temporary dumping areas will be located within 3m away from each excavation face to pile up the excavated materials from the construction and production in a form of trapezoidal bench. The waste earth will be piled according to its amount and piling mode, and the land it occupies is mostly of Gobi. After the construction, the land surface will be protected through covering with gravel. For the purpose of soil and water conservation, engineering measures of watering and covering the surface of the piled earth with dust-prevention net temporarily in strong wind days will be adopted. Page 106 104 The permanent spoil will be transported to the permanent dumping area and piled in a concentrated way when the construction is completed, and the spoil surface will be covered with gravel so as to reduce wind erosion. Ertang Branch Canal Seepage Control Upgrading Works In accordance with the existing status of soil erosion and water loss in the project area and the analysis on the soil erosion and water loss caused by the project construction, the soil erosion and water loss control area is divided into 5 zones, i.e., salient structures area, quarry area, access road area, temporary dumping area, and temporary production area. The main measures for soil and water conservation are as follows: A. Salient structures construction area During the construction period, the temporarily piled materials will be covered with color striped fabric, and watering and other temporary protective measures will be taken for the disturbed ground surface in the construction area. After the construction, the slash of temporary dumping area and the construction area will be leveled. Construction in strong wind day or raining day will be minimized. I t’s forbidden to excavate and pile materials and harden the ground at discretion in construction to minimize damage to the original ground. Rational measures should be taken to protect the soil and water resources. The excavated earth should be utilized as far as possible, and temporary protective measures should be taken for the earth in the period of being piled before the utilization. It’s prohibited to dump and pile the waste earth and other solid wastes at Gobi and other areas not for this purpose, and those wastes must be cleared and transported to the specifically designed storage area and piled in a concentrated way. Covering and retaining measures should also be taken for the temporary storage area. Effective measures should be taken to control and prevent landslide and other soil erosion disasters caused by the construction. The area should be cleared after the construction. B. Quarry area Cobble quarry area is in the riverbed, so it’s difficult to take engineering measures and vegetation measures. The collection of cobbles should minimize the disturbance to the riverbed, and it’s required to collect only the cobbles that are on the top of the riverbed and move from the upper reaches in flood season. No exposal of riverbed is the criterion for cobble collection. C. Access road area The salient works have very convenient access conditions. Natural gradient will be adopted for the onsite access road based on the topographic variation, and the land will be leveled. The salient structures conform to the requirements of soil and water conservation. The construction road will be sprinkled with water during the construction period to avoid dust. D. Temporary dumping area In accordance with the demands of canal works, the dumping areas will be located within 2.5m away from each excavation face to pile up the excavated materials from the Page 107 105 construction and production. The temporarily piled materials will be covered with color striped fabric and be watered. The waste earth will be piled according to its amount and piling mode, and the land it occupies is mostly of Gobi. After the construction, the land surface will be protected through covering with gravel. E. Temporary production area Temporary production and living quarter will be watered to reduce the dust at the construction site. The pollutants (refuse, fuel, etc.) will be cleared or buried after the construction, and the Constructor needs to remove all the surface structures and wastes and transport them to the dumping area. Since the original ground surface of the temporary production and living quarter is covered with gravel, it will be basically free of wind erosion through treatment after the construction. Evaluation on the measures: The above measures can minimize the soil erosion and water loss caused by construction during the construction period. (7) Public health Specific measures: Request the local sanitation and antiepidemic authorities to specially assign person to instruct and supervise the sanitary clearance of the construction area; Organize and implement the health and antiepidemic measures before the mobilization of the construction personnel; Do a good job in treating the ordinary personal injuries and diseases; Strengthen publicization, dissemination and education of health knowledge, and instruct the construction personnel to form good living habits; Ensure the hygiene of food and drinking water at canteen and drinking water supply point and do a good job in sanitation, disinfection, epidemic prevention and immunization so as to eliminate the epidemic outbreak; Earnestly protect the safety of the construction personnel during the construction period to avoid industrial injury. Evaluation on the measures: In case proper sanitary and epidemic prevention measures are taken, the public health of the construction personnel will not be affected. 4.2.3 .3 Mitigation measures during operation period According to the environmental impact analysis on canal building (rehabilitation) works stated in Section 4.1, this type of projects will cause adverse environmental impacts mainly in the construction period, and they will not adversely impact the surroundings during the operation period. Consequently, no mitigation measure is considered during the operation period. Page 108 106 Summary of General Mitigation Measures against Environmental Impacts of Canal Building (Rehabilitation) Works Table 4.2-12 Type Period EI Factor Mitigation Measures Enforcement Unit Supervision Unit Monitoring Unit Design stage The designer should consider all the factors comprehensively, divide the permanent land use plan into more details according to the design of the surroundings, and utilize the land rationally. In the design, the temporary dumping areas for the construction period and the permanent dumping areas after the construction should be arranged reasonably based on the specific conditions of various canal sections, and flood-control tailing hold works and sewage-control tailing hold works should be arranged to control the spoil in a concentrated way and minimize the impact of spoil piling on environment. Soil and water conservation plan should be prepared well. The general layout should fully consider not only the type, mode and impacting degree of soil erosion and water loss caused by the project construction, but also the master plan of the management area for the operation period of the project. Great attention should be attached in design on the public health during the construction period. The dwelling conditions in the temporary living quarter should not be too simple, crude and crowded, and the area with good surroundings should be selected as the living quarter for the construction personnel to prevent the introduction and spreading of epidemic diseases. The construction of the works will cause great noise, so the designer should take reasonable sound insulation and noise reduction measures as required so as to mitigate the impact of construction noise on site construction personnel. Find out the opinions and comments on environmental problems and impacts of the public and all walks of life to be impacted through public participation before, during and after the project development so as to improve the design. Designer Environment workgroup Environmental management offices of Turpan City, Shanshan County, and Tuokexun County — C a n a l B u i l d i n g ( R e h a b i l i t a t i o n ) W o r k s Construction period Production wastewater Production wastewater will be mainly from concrete batching and curing and cleaning and maintenance of transport vehicles and other machinery. Since the construction sites are dispersed, the wastewater from concrete batching and curing is difficult to collect and will be fully consumed through evaporation. Only minor repair and maintenance will be conducted for the mechanical equipment at the site, so the production wastewater is mainly from washing of the batching system which is small in quantity and will be fully consumed through natural evaporation and seepage. Therefore, no mitigation measure will be taken for the production wastewater. Constructor Xinjiang Environmental Protection Department, environmental protection bureaus of Turpan Prefecture, Turpan City, Shanshan County and Tuokexun Page 109 107 Type Period EI Factor Mitigation Measures Enforcement Unit Supervision Unit Monitoring Unit Ambient air Operators for the batching plant will be protected for health care, for example, wearing gauze masks and wind glasses; Cement, lime and other powder materials should be canned or bagged. Transportation in bulk is forbidden so as to prevent dust along the transportation route; Cover the piled materials with tarpaulin in rain and strong wind days; Strictly regulate the traveling route of the transportation machinery during the construction period; Often sprinkle water for curing during the construction period to reduce dust. Water 2-3 times per day or more often in strong wind event; Avoid earth excavation under strong wind weather. Acoustic environment In accordance with the Noise Limits for Construction Site (GB12523-90), the working hours of the people working at the screening system, batching system and other highly noisy environment should be controlled as per the labor protection regulations and be offered with anti-noise articles. Use low-noise equipment as far as possible, and strengthen the maintenance of mechanical equipment. Evaluation on the measures: The above measures can minimize the impact of noise on the construction personnel during the construction period. Engineering spoil Engineering spoil produced in construction is mainly of refused debris and earth. The best solution is to use refused debris and earth as filling materials or backfill materials on the spot to reduce the amount of waste, and the remaining spoil will be piled at the planned dumping area. Domestic garbage Strengthen the propaganda of the Environmental Protection Law and the Soil and Water Conservation Law, intensify the construction personnel’s sense of environmental protection, standardize their behavior in construction, and strictly prohibit them from rolling and damaging soil and vegetation at discretion. Strictly designate the traveling route of vehicles and other construction machinery and set warning signs on both sides of the construction access. Public health Request the local sanitation and antiepidemic authorities to specially assign person to instruct and supervise the sanitary clearance of the construction area; Organize and implement the health and antiepidemic measures before the mobilization of the construction personnel; Do a g ood job in treating the ordinary personal injuries and diseases; Strengthen publicization, dissemination and education of health knowledge, and instruct the construction personnel to form good living habits; Ensure the hygiene of food and drinking wate r at canteen and drinking water supply point and do a good job in sanitation, disinfection, epidemic prevention and immunization so as to eliminate the epidemic outbreak; Earnestly protect the safety of the construction personnel during the construction period to avoid industrial injury.

In the design, the temporary dumping areas for the construction period and the permanent dumping areas after the construction should be arranged reasonably based on the specific conditions of various construction zones, and flood-control tailing hold works and sewage-control tailing hold works should be arranged to control the spoil in a concentrated way and minimize the impact of spoil piling on environment. Soil and water conservation plan should be prepared well. The general layout should fully consider not only the type, mode and impacting degree of soil erosion and water loss caused by the project construction, but also the master plan of the management area for the operation period of the project. Great attention should be attached in design on the public health during the construction period. The dwelling conditions in the temporary living quarter should not be too simple, crude and crowded, and the area with good surroundings should be selected as the living quarter for the construction personnel to prevent the introduction and spreading of epidemic diseases. The construction of the works will cause great noise, so the designer should take reasonable sound insulation and noise reduction measures as required so as to mitigate the impact of construction noise on site construction personnel. Find out the opinions and comments on environmental problems and impacts of the public and all walks of life to be impacted through public participation before, during and after the project development so as to improve the design. 4.2.3.2 Mitigation measures during construction period (1) Water environment Production wastewater Specific measures: Production wastewater will be mainly from concrete batching and curing and cleaning and maintenance of transport vehicles and other machinery. Since the construction sites are dispersed, the wastewater from concrete batching and curing is difficult to collect and will be fully consumed through evaporation. Only minor repair and maintenance will be conducted for the mechanical equipment at the site, so the production wastewater is mainly from washing of the batching system which is small in quantity and will be fully consumed through natural evaporation and seepage. Therefore, no mitigation measure will be taken for the production wastewater. Page 119 117 Domestic sewage Special measures: A. Turpan City Water-Saving Irrigation Works a. The daily domestic sewage discharge will be 16.2m 3 /d (2.31m 3 /d by 7 living quarters) during peak construction period. In accordance with the construction production layout and due to the short construction period of the project, limited domestic sewage discharge and strong evaporation in the project area, it ’s decided that the domestic sewage will be collected in the temporary sewage receiving tank and be consumed through natural evaporation and seepage. Seven tanks are arranged, one for each living quarter. The tank is designed to accommodate 3-day sewage discharge and will have a design capacity of 6.94m 3 and a size of 2m ´ 2m ´ 2m (L ´ W ´ D). b. Seven latrines of brick and concrete structure with a floor area of 6m 2 will be built, one in each living quarter. After the construction, the sewage receiving tanks and latrines will be cleared, disinfected and buried. B. Tuokexun County Water-Saving Irrigation Works a. The construction personnel will stay in the residents’ houses around each construction zone, where the existing living facilities can fully meet the demands of the construction personnel. b. Eight simple lavatories (6m 2 each) will be provided at the seven concentrated construction sites and the temporary production area. Feces from the lavatories will be used as manure after being disinfected with lime. When the project is completed, the sewage receiving tanks and lavatories will be dismantled, be backfilled with the excavated earth after the concrete and gravel bedding course being delivered to the permanent dumping area, and be leveled and compacted. C. Shanshan County Water-Saving Irrigation Works The construction personnel for Shanshan County Water-Saving Irrigation Works will stay in the residential area nearby, so the domestic sewage produced will be collected and treated in a unified way in the residential area, no additional treatment measure will be taken. Evaluation on the measures: The above measures can effectively mitigate the adverse environmental impact of domestic sewage in the construction period. (2) Ambient air Specific measures: Construction personnel will be protected for health care, for example, wearing gauze masks and wind glasses; Cement, lime and other powder materials should be canned or bagged. Transportation in bulk is forbidden so as to prevent dust along the transportation route; cover the piled materials with tarpaulin in rain and strong wind days; Page 120 118 strictly regulate the traveling route of the transportation machinery during the construction period; often sprinkle water for curing during the construction period to reduce dust. Water 2-3 times per day or more often in strong wind event; Avoid earth excavation and backfill under strong wind weather. Evaluation on the measures: The above measures can minimize the impact of atmospheric environment contamination on the construction personnel during the construction period. (3) Acoustic environment Specific measures: Prepare the construction planning well to locate strong noise sources far away from the living quarter of construction personnel, and control the noise of excavators, mixing machines and other equipment within 55dB(A). In accordance with the Noise Limits for Construction Site (GB12523-90), the working hours of the people working with mixing machines, bulldozers, excavators and under other highly noisy environment should be controlled as per the labor protection regulations and be offered with anti-noise articles so as to alleviate injury to construction personnel ’s health caused by noise. Evaluation on the measures: The above measures can minimize the impact of noise on the construction personnel during the construction period. (4) Solid waste Engineering spoil Special measures: A. Turpan City Water-Saving Irrigation Works Do a good job in design and construction planning, use the spoil produced in construction as filling materials or backfill materials on the spot as much as possible to reduce the amount of waste, and the remaining spoil will be transported to the permanent dumping area, which is located at Gobi close to Yaer Township project area and the desilting tank of Aidinghu Township project area and will be used to pile the spoil with the existing depression. B. Tuokexun County Water-Saving Irrigation Works The agricultural water-saving irrigation works involve much earth cut, mainly caused by desilting tank, pipe chases, control gates and anchorage blocks. The earth cut amounts to 507300m 3 , of which 492,800m 3 to be used for backfill and 14500m 3 as refuse. Mostly of the earth from pipe chase excavation will be used for backfill. The pipework will produce 8600m 3 of spoil, which can be built into a pipe dyke along the pipeline. The dyke will be 0.6m wide on the bottom, 0.15m high and 1:1.3 in slope ratio. The spoil from pipework can be fully utilized on the spot. The anchorage blocks will be precast and cause 1500m 3 of spoil, which can be used to build the pipe dyke since the anchorage blocks are arranged along the pipeline. When the desilting tank is built, the spoils will be used to level the land around the desilting tank and then be compacted. The land leveling will be 5m wide, 2794m 2 Page 121 119 in area, and 0.5m in thickness, using 1400m 3 of spoil, and the remaining 2800m 3 will be delivered to the permanent dumping area. The spoil from building of control gates is quite little, only 200m 3 , and the way to treat it is similar to that for the desilting tank. C. Shanshan County Water-Saving Irrigation Works The solid waste from the construction covers refused earth, sand and stone excavated, and refused bricks. The refused earth produced in the earth excavation is quite little because the earth is used for backfill while being excavated in the process of pipeline laying and the rest is blocked up along the pipeline to build into a pipe dyke, thus excavation and backfill are balanced basically. When the rehabilitated pump wells, gate well valves and inspection wells are built, the earth, sand, stone, and refused bricks from the excavation can be used to level the land around the excavation site, then be compacted, and finally be covered with gravel on the surface. Since the surplus earth is of perennial cultivated soil, it can be evenly scattered to farmland again. The earth can be reused although it is waste. Domestic garbage Special measures: A. Turpan City Water-Saving Irrigation Works a. Provide seven movable garbage collectors, one in each living quarter, publicize the hygiene knowledge to the construction personnel, and nurture their habit of putting garbage into garbage collector. b. Rent one refuse truck every week during the construction period to collect, clear and transport the garbage in time, and treat the garbage together with that from the local residents. B. Tuokexun County Water-Saving Irrigation Works The peak domestic garbage yield will be 0.36t daily, and the total domestic garbage yield during the whole construction period will be about 106t. Since the construction personnel will stay in the residents ’ houses around each construction zone, the existing living facilities can be utilized. However, one movable garbage collector needs to be arranged at the seven main construction sites and the temporary production area separately. The domestic garbage will be transported to Tuokexun County wasteyard for treatment. C. Shanshan County Water-Saving Irrigation Works The construction personnel for Shanshan County Water-Saving Irrigation Works will stay in the residential area nearby, so the domestic garbage produced will be collected and treated in a unified way in the residential area, no additional treatment measure will be taken. Evaluation on the measures: The above measures can lower the impact of solid waste in construction on the surroundings to a degree within environmental endurance. (5) Ecological environment Specific measures: Page 122 120 Strengthen the propaganda of the Environmental Protection Law and the Soil and Water Conservation Law, intensify the construction personnel ’s sense of environmental protection, standardize their behavior in construction, and strictly prohibit them from rolling and damaging soil and vegetation at discretion; Strictly designate the traveling route of vehicles and other construction machinery, mark clearly the area of construction activities at the site, and set warning signs on both sides of the construction access. Evaluation on the measures: The above measures can effectively protect the ecological environment around the project area. (6) Soil and water conservation measures Special measures: Turpan City Water-Saving Irrigation Works A. Diversion gate, desilting tank, management room and gate valve well works area It mainly includes diversion gate, diversion canal, desilting tank, concentrated surface water treatment station, pump room, management room, gate valve well and other structures, and occupies 10.88hm 2 of land, of which 0.0425hm 2 for the diversion gate and diversion canal, 1.18hm 2 for the desilting tank, 0.35m 2 for the management room and pump room, and 9.31hm 2 for the gate valve well. All the construction of the diversion gate, desilting tank, management room and gate valve well will be concentrated during the period from October to November of 2009, so the strong wind season lasting from every March to April will be avoided. The earth excavation will be done with 1m 3 excavator, accompanied by 15t dump truck for transport. A means of consecutive excavation, loading and transport is adopted. The excavated earth for backfill will be directly transported by dump truck to the place to be backfilled. If the place cannot be backfilled for the moment, the backfilling material will be piled beside the place in a concentrated way and be subject to temporary watering and hardening treatment. The earth not for backfill will be directly transported to the permanent dumping area. B. Pipeline works area The pipeline works area includes the main diversion pipe and field pipeline network works and occupies 50.11hm 2 of land. The main diversion pipe is 7580m and occupies 2.57hm 2 of land in total, and the field pipeline totals 453.867km long and occupies 47.54hm 3 of land. The excavated materials will be piled up in a concentrated way on one side of the excavated section within the managed scope. The earth will be piled in trapezoidal bench with a slope ratio of 1:1. The temporary piling height of the excavated materials for the main diversion pipe is controlled at 2.0m because it is in Gobi, and that for the field pipeline is controlled at 1.0m because it is in oasis farmland. The temporary spoil from the main diversion pipe can be watered and temporarily hardened with the water from canal, and that from the field pipeline can be compacted solidly with manpower for an earth layer of 5cm thick on the windward side. The slash of temporary dumping area and the construction area will be leveled after the construction. Page 123 121 C. Access road area Access road area includes maintenance road (7.58km long) and temporary construction road (22km long) and occupies 13.20hm 2 of land, of which 2.27 hm 2 for the maintenance road and 10.93hm 2 for the temporary construction road. The land for the maintenance road and temporary construction road will be leveled, and the earth produced therefrom should be stored concentratedly and be treated with corresponding temporary watering and protective measures. In accordance with the construction requirements, the earth from roadbed excavation should be transported to the place to be backfilled for roadbed, thus the soil erosion due to temporary earth piling can be reduced. Water sprinkling against dust will be carried out during the construction period. D. Dumping area In line with the characteristics and procedures of site construction, a large amount of spoil produced in the construction can be reused and needs to be stored temporaries. Therefore, a temporary dumping area needs to be built, mainly for the diversion gate, desilting tank, main diversion pipe, field pipeline and gate valve well works area, and it will occupy 99.38hm 2 of land. a. Permanent dumping area In accordance with the master plan of the project, two permanent dumping areas are arranged to meet the demands of production, located in Gobi close to Yaer Township project area and desilting tank in Aidinghu Township project area, respectively. The two areas will occupy 1.47hm 2 of land. The permanent dumping area will mainly accommodate the spoil from the diversion gate and the desilting tank. The dumping area is situated 200m away from the diversion gate and desilting tank and is close to the original canal, so it ’s convenient for water use and can be watered more during the construction period so as to lessen soil erosion. Cobbles and rock blocks with a diameter greater than 5cm will be picked out from the spoil pile nearby by manpower during the construction period and be transported to the permanent dumping area by 5t dump truck when the construction is completed to cover over the top and slope corners of the dumping area. The gravel coverage will be 10cm thick, and it will be spread and leveled with manpower and be compacted with 8-10t mechanically driven smooth wheel road roller. b. Temporary dumping area In line with the characteristics and procedures of site construction, a large amount of spoil produced in the construction can be reused and needs to be stored temporaries. Therefore, a temporary dumping area needs to be built, mainly for the diversion gate, desilting tank, main diversion pipe, field pipeline and gate valve well works area, and it will occupy 99.38hm 2 of land. Temporary dumping area for diversion gate and desilting tank Page 124 122 The temporary dumping area for the diversion gate and desilting tank is located 50m away from the construction side and is close to the original canal, so it ’s convenient for water use and can be watered more during the construction period so as to lessen soil erosion. Temporary dumping area for main diversion pipe The temporary dumping area for the main surface water diversion pipe is arranged by the pipe. It is 0.5m away from the pipe duct and between the canal and the pipe, so its surface can be sprinkled with water pumped from the canal during the construction period so as to lessen soil erosion. Temporary dumping area for gate valve well The gate valve well works area is on the boundary of the existing farmland, and currently the farmland, roads and shelterbelt are arranged in order and reasonably and have the function of soil and water conservation to some extent. All the temporary dumping areas for the gate valve wells are located beside the corresponding gate valve well. The windward side of the temporary spoil pile will be compacted solidly with manpower for a thickness of 5cm during the construction period. The temporary land occupied for the works do not have vegetation except the field pipeline network area, where the main vegetation is field weeds. The construction is scheduled from October to November, when the crops will have been reaped and the weeds will be withered and yellow. When excavating the pipe duct, top mellow soil of 30~50cm thick with grass roots and seeds will be took off and piled on the lowermost of the temporary spoil, and when backfilling the pipe duct after the pipes are installed, it will be put on the uppermost. Thus the vegetation will be resumed naturally in the next year. Temporary dumping area for field pipeline network The field pipeline network is in the existing farmland without exception, and currently the farmland, roads and shelterbelt are arranged in order and reasonably and have the function of soil and water conservation to some extent. All the temporary dumping areas for the field pipeline network are located along the network. The windward side of the temporary spoil pile will be compacted solidly with manpower for a thickness of 5cm during the construction period. The construction is scheduled from October to November, when the crops will have been reaped and the weeds will be withered and yellow. When excavating the pipe duct, top mellow soil of 30~50cm thick with grass roots and seeds will be took off and piled on the lowermost of the temporary spoil, and when backfilling the pipe duct after the pipes are installed, it will be put on the uppermost. Thus the vegetation will be resumed naturally in the next year. E. Temporary production and living quarter The temporary production and living quarter includes temporary production area and temporary living area. The temporary production area covers the places for concrete batching system, aggregate processing system, equipment repairing workshop, rebar processing workshop, wood workshop, parking lot, construction equipment warehouse, consumption goods warehouse, cement storage, fuel storage, and so on. The temporary living area covers the places for office, dormitory, work shed, temporary piling and transfer areas, and so on and will occupy 0.38hm 2 of land. Page 125 123 The temporary production and living quarter will be watered to reduce the dust at the construction site. The pollutants (refuse and fuel) will be cleared or buried after the construction, and the Constructor needs to remove all the surface structures and wastes and transport them to the dumping area. Since the original ground surface of the temporary production and living quarter is covered with gravel, it will be basically free of wind erosion through leveling of the temporarily occupied land (0.38 hm 2 ) after the construction. The engineering measures above mentioned are newly added for soil and water conservation. Tuokexun County Water-Saving Irrigation Works A. Field pipeline control area The pipeline control area covers the gate valve well and field pipeline network works. The excavated materials will be piled up in a concentrated way on one side of the pipe duct in trapezoidal bench with a slope ratio of 1:1 and a height controlled at 1.0m.

The temporary production and living quarter will be watered to reduce the dust at the construction site. The pollutants (refuse and fuel) will be cleared or buried after the construction, and the Constructor needs to remove all the surface structures and wastes and transport them to the dumping area. Since the original ground surface of the temporary production and living quarter is covered with gravel, the temporarily occupied land (0.70 hm 2 ) will be leveled after the construction. Page 126 124 E. Preventive management measures To reduce the soil erosion in construction, management of various construction stages should be intensified besides the specific engineering measures. a. The temporarily stored earth to be transferred and utilized should be piled into bench and compacted solidly on the surface to avoid wind erosion. In addition, the Constructor should arrange the construction procedures rationally to minimize the time of temporary storage of earth. b. Plan the range of construction activities during the construction period, and arrange the existing traffic at the sections with quite strong wind erosion, specially assign person to strictly control and manage the traveling route of transport vehicles and heavy machinery to prevent damage to ground surface and vegetation and the soil erosion arising thereof. c. Set up warning boards for vegetation protection at the passageway of service roads to remind the construction personnel and operators. d. No construction in strong wind or rainstorm weather, especially the excavation and backfill of pipe ducts. e. Strictly prohibit the pile and place the construction materials in disorder to prevent enlarging the damage to ecological environment. Shanshan County Water-Saving Irrigation Works Its construction area consists of 9 construction zones, 15 subzones and 60 control areas for the control of soil erosion and water loss. In accordance with the existing status of soil erosion in the project area and the analysis on the soil erosion caused by the project construction, and due to the fact that the control areas and the corresponding construction method and content are the same for the various construction zones, the soil erosion control system is designed only for the four control areas of one subzone of one construction zone. The four control areas are the management room control area, pipeline control area, temporary construction road control area, and temporary production and living control area. The major soil and water conservation measures are as below: Management room control area: The excavated materials will be piled up in a concentrated way on one side in trapezoidal bench with a slope ratio of 1:1 and a height controlled at 1.0m, and its windward side will be compacted solidly with manpower as a temporary measure. The slash of temporary piling area for the excavated materials will be leveled after the construction. Pipeline control area: The materials from pipeline excavation will be piled up in a concentrated way along one side of the pipeline in trapezoidal bench with a slope ratio of 1:1 and a height controlled at 1.0m, and its windward side will be compacted solidly with manpower as a temporary measure. The slash of temporary piling area for the excavated materials will be leveled after the construction. Page 127 125 Temporary construction road control area: The construction roads are mainly in the farmland. They will be temporarily protected through watering during the construction period and can be directly used for re-cultivation when the construction is completed. Temporary production and living control area The temporary production and living quarter includes temporary production area and temporary living area. The temporary production area covers the places for concrete batching system, aggregate processing system, equipment repairing workshop, rebar processing workshop, wood workshop, parking lot, construction equipment warehouse, consumption goods warehouse, cement storage, fuel storage, and so on. The temporary living area covers the places for office, dormitory, work shed, temporary piling and transfer areas, and so on. The temporary production and living quarter will be watered to reduce the dust at the construction site. The pollutants (refuse and fuel) will be cleared or buried after the construction, and the Constructor needs to remove all the surface structures and wastes and transport them to the wasteyard. Since the original of the temporary production and living quarter is covered with gravel, the ground surface will be basically free of wind erosion through treatment of the temporarily occupied land after the construction. The engineering measures above mentioned are newly added for soil and water conservation. (7) Public health Specific measures: Request the local sanitation and antiepidemic authorities to specially assign person to instruct and supervise the sanitary clearance of the construction area; Organize and implement the health and antiepidemic measures before the mobilization of the construction personnel; Do a good job in treating the ordinary personal injuries and diseases; Strengthen publicization, dissemination and education of health knowledge, and instruct the construction personnel to form good living habits; Eliminate the epidemic outbreak; Earnestly protect the safety of the construction personnel during the construction period to avoid industrial injury. Evaluation on the measures: In case proper sanitary and epidemic prevention measures are taken, the public health of the construction personnel will not be affected. 4.2.3.3 Mitigation measures during operation period During operation period, the environmental impacts of water saving irrigation works will be mainly certain adverse environmental impacts caused by change of agro-chemical uses. The mitigation measures are summarized in table 4.1.1.4. Page 128 126 Summary of General Mitigation Measures against Environmental Impacts of Water Saving Irrigation Works Table 4.2-14 Type Period EI Factor Mitigation Measures Enforcement Unit Supervision Unit Monitoring Unit Design stage The designer should consider all the factors comprehensively, divide the permanent land use plan into more details according to the design of the surroundings, and utilize the land rationally. In the design, the temporary dumping areas for the construction period and the permanent dumping areas after the construction should be arranged reasonably based on the specific conditions of various construction zones, and flood-control tailing hold works and sewage- control tailing hold works should be arranged to control the spoil in a concentrated way and minimize the impact of spoil piling on environment. Soil and water conservation plan should be prepared well. The general layout should fully consider not only the type, mode and impacting degree of soil erosion and water loss caused by the project construction, but also the master plan of the management area for the operation period of the project. Great attention should be attached in design on the public health during the construction period. The dwelling conditions in the temporary living quarter should not be too simple, crude and crowded, and the area with good surroundings should be selected as the living quarter for the construction personnel to prevent the introduction and spreading of epidemic diseases. The construction of the works will cause great noise, so the designer should take reasonable sound insulation and noise reduction measures as required so as to mitigate the impact of construction noise on site construction personnel. Find out the opinions and comments on environmental problems and impacts of the public and all walks of life to be impacted through public participation before, during and after the project development so as to improve the design. Designer Environment workgroup Environmental management offices of Turpan City, Shanshan County, and Tuokexun County W a t e r - S a v i n g I r r i g a t i o n W o r k s Construction period Production wastewater Production wastewater will be mainly from concrete batching and curing and cleaning and maintenance of transport vehicles and other machinery. Since the construction sites are dispersed, the wastewater from concrete batching and curing is difficult to collect and will be fully consumed through evaporation. Only minor repair and maintenance will be conducted for the mechanical equipment at the site, so the production wastewater is mainly from washing of the batching system which is small in quantity and will be fully consumed through natural evaporation and seepage. Therefore, no mitigation measure will be taken for the production wastewater.

In accordance with the construction production layout and due to the short construction period of the project, limited domestic sewage discharge and strong evaporation in the project area, it’s decided that the domestic sewage will be collected in the temporary sewage receiving tank and be consumed through natural evaporation and seepage. Seven tanks are arranged, one for each living quarter. The tank is designed to accommodate 3-day sewage discharge and will have a design capacity of 6.94m 3 and a size of 2m ´ 2m ´ 2m (L ´ W ´ D). Seven latrines of brick and concrete structure with a floor area of 6m 2 will be built, one in each living quarter. After the construction, the sewage receiving tanks and latrines will be cleared, disinfected and buried. Engineering spoil Do a good job in design and construction planning, use the spoil produced in construction as filling materials or backfill materials on the spot as much as possible to reduce the amount of waste, and the remaining spoil will be transported to the permanent dumping area, which is located at Gobi close to Yaer Township project area and the desilting tank of Aidinghu Township project area and will be used to pile the spoil with the existing depression. Turpan City Turpan City Turpan City Water- Saving Irrigation Works Turpan City Water- Saving Irrigation Works Domestic garbage Provide seven movable garbage collectors, one in each living quarter, publicize the hygiene knowledge to the construction personnel, and nurture their habit of putting garbage into garbage collector.

All the construction of the diversion gate, desilting tank, management room and gate valve well will be concentrated during the period from October to November of 2009, so the strong wind season lasting from every March to April will be avoided. The earth excavation will be done with 1m 3 excavator, accompanied by 15t dump truck for transport. A means of consecutive excavation, loading and transport is adopted. The excavated earth for backfill will be directly transported by dump truck to the place to be backfilled. If the place cannot be backfilled for the moment, the backfilling material will be piled beside the place in a concentrated way and be subject to temporary watering and hardening treatment. The earth not for backfill will be directly transported to the permanent dumping area. Pipeline works area: It includes the main diversion pipe and field pipeline network works and occupies 50.11hm 2 of land. The main diversion pipe is 7580m and occupies 2.57hm 2 of land in total, and the field pipeline totals 453.867km long and occupies 47.54hm 3 of land The excavated materials will be piled up in a concentrated way on one side of the excavated section within the managed scope. The earth will be piled in trapezoidal bench with a slope ratio of 1:1. The temporary piling height of the excavated materials for the main diversion pipe is controlled at 2.0m because it is in Gobi, and that for the field pipeline is controlled at 1.0m because it is in oasis farmland. The temporary spoil from the main diversion pipe can be watered and temporarily hardened with the water from canal, and that from the field pipeline can be compacted solidly with manpower for an earth layer of 5cm thick on the windward side. The slash of temporary dumping area and the construction area will be leveled after the construction. Access road area: Access road area includes maintenance road (7.58km long) and temporary construction road (22km long) and occupies 13.20hm 2 of land, of which 2.27 hm 2 for the maintenance road and 10.93hm 2 for the temporary construction road. The land for t he maintenance road and temporary construction road will be leveled, and the earth produced therefrom should be stored concentratedly and be treated with corresponding temporary watering and protective measures. In accordance with the construction requi rements, the earth from roadbed excavation should be transported to the place to be backfilled for roadbed, thus the soil erosion due to temporary earth piling can be reduced. Water sprinkling against dust will be carried out during the construction period . Dumping area: In line with the characteristics and procedures of site construction, a large amount of spoil produced in the construction can be reused and needs to be stored temporaries. Therefore, a temporary dumping area needs to be built, mainly for the diversion gate, desilting tank, main diversion pipe, field pipeline and gate valve Page 132 130 Location Description EI Factor Mitigation Measures Enforcement Unit Supervision Unit Monitoring Unit Domestic sewage The construction personnel will stay in the residents’ houses around each construction zone, where the existing living facilities can fully meet the demands of the construction personnel. Eight simple lavatories (6m 2 each) will be provided at the seven concentrated construction sites and the temporary production area. Feces from the lavatories will be used as manure after being disinfected with lime. When the project is completed, the sewage receiving tanks and lavatories will be dismantled, be backfille d with the excavated earth after the concrete and gravel bedding course being delivered to the permanent dumping area, and be leveled and compacted. Engineering spoil The agricultural water-saving irrigation works involve much earth cut, mainly caused by desilting tank, pipe chases, control gates and anchorage blocks. The earth cut amounts to 507300m 3 , of which 492,800m 3 to be used for backfill and 14500m 3 as refuse. Mostly of the earth from pipe chase excavation will be used for backfill. The pipework will produce 8600m 3 of spoil, which can be built into a pipe dyke along the pipeline. The dyke will be 0.6m wide on the bottom, 0.15m high and 1:1.3 in slope ratio. The spoil from pipework can be fully utilized on the spot. The anchorage blocks will be precast and cause 1500m 3 of spoil, which can be used to build the pipe dyke since the anchor age blocks are arranged along the pipeline. When the desilting tank is built, the spoils will be used to level the land around the desilting tank and then be compacted. The land leveling will be 5m wide, 2794m 2 in area, and 0.5m in thickness, using 1400m 3 of spoil, and the remaining 2800m 3 will be delivered to the permanent dumping area. The spoil from building of control gates is quite little, only 200m 3 , and the way to treat it is similar to that for the desilting tank.

Engineering spoil The solid waste from the construction covers refused earth, sand and stone excavated, and refused bricks. The refused earth produced in the earth excavation is quite little because the earth is used for backfill while being excavated in the process of pipeline laying and the rest is blocked up along the pipeline to build into a pipe dyke, thus excavation and backfill are balanced basically. When the rehabilitated pump wells, gate well valves and inspection wells are built, the earth, sand, stone, and refused bricks from the excavation can be used to level the land around the excavation site, then be compacted, and finally be covered with gravel on the surface. Since the surplus earth is of perennial cultivated soil, it can be evenly scattered to farmland again. The earth can be reused although it is waste.

Since construction sites will be arranged in a relative scattered way, it is not easy to collect together the dust and wastewater from concrete batching and concrete care. The main contents mainly consist of solid matters as mud, sands, rock debris. Except poor SS values, the wastewater would not occur a large quantity and basically have a big content of toxicant, the wastewater to be occurred will be naturally evaporated or seepage; Page 137 135 B. The application of construction material will conform to related requirements, particularly the treatment of grout. Before grout injection, water body and shaft wall shall be given partition protection to protect them from contamination by construction material; C. Before consolidation with the shafts, buried channel top should be covered temporarily to prevent entrance of running oil, spilled oil, oil drop and oil leakage from construction machinery; D. After the consolidation with the buried channels and shafts, all solid deposition accumulated along the channels such as sediment and rock debris shall be dredged out completely. Evaluation: Applications of the aforesaid measures will effectively mitigate the unfavorable impacts of production wastewater on the water in kareses and ambient environment in the vicinity. domestic sewage Specific measures: A. Daily domestic sewage discharge peak will reach 1.91m 3 /d during construction period. The construction production layout shows that only septic tank and natural evaporation and leakage can satisfy demands due to short-term construction period and limited domestic sewage discharge and local high evaporation. A temporary septic tank with a capacity based on 3-day discharge will be provided in living area. This tank is designed to have a capacity of 5.73m 3 , sized 2m length by 2m width by 1.5m depth, concrete structure, 20cm thick bottom and 10cm thick cushion made of gravels. After flowing into the septic tank, domestic sewage will experience sedimentation, disinfection and evaporation; finally the residual solid deposition will be used in green work by local farmers. After the completion of construction, septic tank will be cleaned, disinfected and buried. B. One brick-concrete waterless toilet in a building floor area of 6m 2 will be built in the living area, and cement masonry will be done for lining purpose. Feces to be occurred will be collected and used for green work. After the completion of construction, this waterless toilet will be cleaned, disinfected and buried. Evaluation: Applications of the aforesaid measures will effectively mitigate the unfavorable impacts of domestic sewage on the environment. 2Ambient air Specific measures: give hygienic protection to the operators of batching plant, for i nstance, provision of respirator, goggles, etc.; powder like material, such as cement, lime, etc. should be transported by tank truck or in bags. Transportation in bulk must be forbidden. No dust dispersion may be allowed. Stacking material will be covered by awning cloth in case of rain and strong wind days; Traveling line of transportation vehicles should be set out strictly during construction period.

Page 183 181 Chapter 9 Cost Estimation and Fund Source of Environmental Management 9.1 Allocation of Budget EMP will concern many intuitions, fund sources will therefore be different. Most environmental protection activities will be engineering measures. In view of this, engineering measures will be provided by project contraction contractors and operators and list in project cost. The lines of the cost will be classified in list in their competitive bids. EMP budget will be mainly used for the environmental management during construction period and operation period, including: environmental monitoring, environmental supervision, personnel training, and environmental management institution functioning and risk resistance for some projects. EMC activities will be included in the budget for PMO, PIUs international project management, monitoring over water quality/air/noise, the same as CSEE and EFSI. CSEE ’s monitoring and supervision activities will be the part of budget for building and supervision. Project Owners will bear monitoring cost. If routine monitoring of local environmental protection institutions will be done concurrently with that of this project, the data coming from routine monitoring executed by local environmental protection institutions can be used. 9.2 Fund Sources and EMP Budget The summary of environmental management cost for all project components during construction period sees Table 9.2-1.

Temporary stacking ground will be equipped with covering and retaining measures to keep the material in order. The solid waste will be dumped only at designated places. Effective measures will be taken to prevent geological hazards such as slope slide in engineering activities. After the completion of the construction, the engineering site will be cleared. The material ground of pebbles is located on riverbed, where the vegetation rehabilitation is impossible. In collecting pebbles, there will be as little disturbance to the riverbed as possible. Only the surface pebbles are collected. The criteria is the riverbed will not become of exposure. Road Building Site: The engineering site is convenient in access to the outside. The construction of the in-site road will take advantage of the natural slope. Water-spraying will be done in the construction period for dust depression. Therefore, the requirements for soil conservation are satisfied. To satisfy the needs in the canal construction, the stacking ground of the excavated will be located within 2.5 m from each of the engineering sites. Measures of covering and water-spraying will be taken for dustproof. The occupied land is basically a piece of Gobi desert. After the completion of the construction, the engineering site will be mulched with gravels. In the construction period, the dust in the temporary production area and living quarter will be depressed by water-spraying. After the completion of the construction, the pollutants such as garbage and oily matters will be cleared or landfilled. The ground structures will be demolished and transported to the dump ground. Since the site was originally covered with gravels before the construction, the proper land treatment can basically prevent the temporarily occupied land from wind erosion.

The pollutants in the wastewater are mainly silt, debris and other solid wastes. Except the fact that the SS indicator is poor, there is basically no other toxic or harmful substance and the quantity is very small if ever. Since the engineering sites are scattered allover, this wastewater will disappear by evaporation and seepage. Relevant stipulations on the materials to be used for such project should be highly respected. In particular, water body should be kept safe from the shaft wall before the process of grouting. All the possible measures will be taken to prevent the water body and shaft wall from the pollution by an engineering material. When reinforcing a shaft, a temporary safeguard plate must be put over the underground canal to prevent the water from oily pollutant(s) from engineering activities. After the completion of reinforcing the underground canal and shaft, all the solid wastes such as muddy sand and rock debris must be cleared up. Since the evaporation in the project area is intensive and the engineering period is short and there is not much domestic sewage at each site, the sewage will be collected in a temporary sewage tank for natural evaporation and seepage. One set of temporary sewage tank will be constructed in the living quarter. After the completion of the construction, the sewage tank will be cleared, disinfected and buried. One set of dry toilet of brick -concrete structure will be built in the living quarter. Cement laid stone masonry will be used for anti- seepage treatment. After the completion of the construction, the dry toilet will be cleared, disinfected and buried. 31.262 Contractor Turpan City Bureau of Environmental Protection; Turpan Prefecture Bureau of Environmental Protection Page 269 267 Environmental Impact Factor Mitigation Measures Cost (10,000 RMB) Executing Agency Supervising Agency Air Environment The engineering staff will be properly protected for safe production. They will be access to protective things such as respirators, goggle and so on. Powder materials such as cement and lime will be carried in containers or bags. It is forbidden to scatter and lose powder materials in transport to generate dust. The materials will be covered with tarpaulin in rainy and windy conditions. The routes of the engineering vehicles and other machines will be strictly stipulated. Water-spraying will be regularly done to depress dust in the construction period. The wastes from dredging will be properly manage both in and after the period of the project activities. Acoustic Environment In operation, the noise of machines such as drilling machine, excavator and concrete mixer will be controlled below 55 dB(A). In accordance with Noise Limits for Construction Site (GB12523 - 90), the daily working time of the staff working in strong noise environment such as operating concrete mixer and drilling machine will be controlled within the limit of labor insurance, and these staff will be access to noiseproof wares. Low -noise equipment will be employed, if applicable. In addition, the repair and maintenance of machinery will be strengthened. Solid Waste Each of the temporary living quarter will be equipped wi th mobile recycling collection point and garbage bins (2 sets). Information publicity on sanitation will be strengthened for capacity building of sanitation and environmental protection among the engineering staff. In the construction period, one set of garbage truck will be employed every week to carry the domestic garbage to the garbage dump ground. Ecological Environment Information publicity on the Law of Environmental Protection and Law of Soil Conservation will be strengthened, so as to upgrade the engineering staff in the awareness of environmental protection and to keep the vegetation and soil conditions from damage. The routes of the engineering vehicles and other machines will be strictly stipulated. Signing boards will be erected at the engineering sites and the roads. Measures of Soil Conservation A. Main Construction Area: The earthwork from the Karez dredging and the residues from drilling machine will be take out from the shaft. They will be stacked around the shaft with height of 0.5~1.5 m and internal/external slope of 1.75. The surface will be compacted and covered. The site will be cleared after the completion of the engineering. B. The land to be occupied by temporary engineering road will be a piece of Gobi desert with gravels all over and without vegetation coverage. Before the engineering, only some land leveling measures of slope cut and land fill will be taken. There will be a balance between the excavation and land fill to reduce residue production. C. Permanent dump ground will be located at the external side of the original soil ridge around each of the shaft. After the completion of the construction, the residues will be arranged as ring ridge on the external side of the original soil ridge. These 2 ring ridges will be integrated, mulched with gravels and compacted to prevent wind erosion.
