Project Background This document summarizes the environmental impact assessment of the World Bank financed Yan’an Water Supply Project (YWSP), highlighting the main issues and conclusions of the environmental impact assessment (EIA) and environment management plan (EMP) for YWSP. According to both the Chinese Environmental Assessment laws and the World Bank’s Operational Policy 4.01 Environmental Assessment, the proposed project is classified as Category A for environmental assessment purposes, due to the scale and significance of potential environmental and social impacts. Therefore, a full environmental assessment report was required. The project is estimated to cost about 1.041 billion RMB, of which the World Bank is to finance US$ 60 million; the rest will be financed by the Borrower’s counterpart funds. In accordance with Chinese internal review and approval procedures, an EIA report together with an EMP was prepared for YWSP by the Shaanxi Hydropower Investigation, Design & Research Institute (SHIDRI). The Chinese EIA report for YWSP has been reviewed and approved by the Shaanxi Provincial Environmental Protection Department (SEPD) in 2009. This Executive Summary is based on a modified EIA and EMP which reprepared by SHIDRI in accordance with the World Bank environment policy, as well as feasibility studies carried out for the project. The EA reports and EMP were submitted to the World Bank for review and they fully conform to the Bank policy guidelines regarding environmental and social issues. All reports mentioned above will be made available in China and in the Public Information Center (Infoshop) of the World Bank. 2. Project Development Objectives The development objective of the proposed project is to: a) expand the water supply for Yan’an city through supplemental water diversion b) improve the management of the raw water supply system by integrating the institutions for supply of water and c) institute a demand management system so that water demand can be contained. The economy and population of the Yan’an city have grown rapidly during the past decade. Water has become the number one bottleneck for the continued socio-economic development of the municipality. The existing water sources are no longer able to provide reliable water in sufficient quantity to the urban and rural residents even for drinking purpose. Also some key industrial enterprises such as Yanchang Oil Company are confronted with the issue of reducing and possibly shutting down production because of water shortage if immediate actions were not taken to bring additional water to the area. The water shortage in Yan’an is to get worse according to conducted water resources assessment studies. The proposed project is intended to help address this challenge and enhance the water supply security in Baota District to benefit a population of 500,000. Yan’an will use the Yellow River as the water source since the smaller rivers in the area have either insufficient volume or inadequate water 1 quality to supply the core city and the urban areas in the surrounding counties. Figure 1 shows the geographic location and layout of the proposed project. Figure 1 Geographic location and layout of the proposed project 3. Environmental Assessment Process and Legal Framework A full Environmental Assessment (EA) was carried out in accordance with Chinese EIA Law and relevant regulations and World Bank environmental safeguard policies. The project triggered the following World Bank Policies: Environmental Assessment (OP/BP 4.01), Natural Habitats (OP/BP4.04), Involuntary Resettlement (OP/BP 4.12); and Safety of Dams (OP/BP 4.37). Compliance with these policies, and the World Bank’s disclosure of information policy, is summarized in Table 1.

The sludge from water treatment plant (WTP) during operation phase will be treated before disposal. Water Pollution Prevention and Mitigation measures are built into the EMP based on the Water Control Law Resources Assessment Report developed for this project. Based on a special study, water and soil conservation plan and mitigation measures were developed and incorporated into the EMP. Water and Soil Conservation Law The plan will be specified in bid documents for contractors to allow for implementation. Consultations with local cultural property authorities in the project Cultural Property Law counties and cities were held. Chance finding procedures will be followed. Tentative Method for Public Public consultation was conducted following the tentative method Participation in EIA during the preparation of the EIA. 4. Project Description The proposed project will abstract 12.75 MCM water annually from the Yellow River at Wangjiaqu in Yanchuan County onward transfer to Yan’an city by 2020, and 27.77 MCM water annually by 2030. The total length of the conveyance works from Wangjiaqu intake in Yanchuan County to the outlet of Dongchuan WTP in Yan’an is 83 km, including six online booster pump stations. To address special 3 circumstances such as excessive sand content (greater than 60 kg/m3) in the Yellow River water under certain river flow conditions and/or at very low flow rate (smaller than100 m3/s) in which drawing water from the Yellow River is no longer appropriate, it is proposed to construct a reservoir in Baishugua for storage and regulating. Also, a reservoir will be built in Kanjiagou for maintenance backup. Meanwhile, at the end of transfer line, one water treatment plants will be constructed in Dongchuan for full treatment. The proposed project scope however covers only the transfer works from the inlet of Gaojiawan pump station to the Dongchuan WTP, and associated pump stations, transmission pipes, reservoir, and the aforementioned water treatment plant. Due to a tight timeframe and expected long construction period, Yan’an has chosen to finance the section from the raw water intake to the inlet of Gaojiawan pump station with its own funds.

Environmental Baseline 5.1 Physical Environment Topography and Landscape The proposed project is located in the center of northern Shaanxi loess plateau, where topography is featured in hilly area, including numerous of valleys, ravines and gully. The elevation of northwest terrain is higher than that in southwest with an attitude between 800 and 1800 meter. Most of the valleys are narrow and deep, both sides are broken terrain, with V shaped cross-section. The bottom widths of the valley are ranges from 30 to 60 meter and terraces were developed when the channel is wide enough. Regional Geology The project area is in the monocline structure area of Northern Shaanxi Depressions of Ordos platform syncline. There is no regional tectonic fault, folds are not developed. Neotectonics movement is gently uplifting in a large-scale with small difference. The crust is relatively stable. The project area basic seismic intensity is Ⅵ. Groundwater in the project area can be classified as Quaternary pore diving and Triassic bedrock fissure water. As the area broken terrain and poor storage condition in the rock, coupled with low annual precipitation, groundwater resources are poor. Climate 6 The project area belongs to the temperate semi-arid continental monsoon climate and enjoys four C distinct seasons. The annual mean temperature is 9.4 º with an extreme high temperature of 39.7 C C º (June 21, 1966) and an extreme low temperature of -25.4 º (Jan 22, 1967). The monthly mean C, temperature in January is -6.4 º and monthly mean temperature in July is 22.9 º C. The duration of annual sunshine is 2,445 hours. Average annual precipitation is 493 mm with an uneven spatial and temporal distribution. Precipitation gradually declines from the south to the north and two-thirds of it is concentrated during the months from June to September. Average annual evaporation is 983 mm. Southwest winds prevailed throughout the year. The annual average wind speed is 2.0 m/s, while the maximum wind speed is 18 m/s. The maximum depth of frozen soil in the area is 79 cm. River System and Water Resources Yan’an municipality is in a region which is extremely short of water. The per capita water resources is 463 m3 compared to the national average of 2,200 m3, and the international threshold for extreme water scarce regions of 1,000 m3. The following factors make things worse: (i) a rather uneven temporal distribution of Yan’an’s 493 mm annual precipitation, with over 70% concentrated in the months of June-September; (ii) sedimentation resulting from soil erosion of the Loess Plateau which reduces the limited storage capacity of the existing water source reservoirs; and (iii) heavy water pollution and water quality deterioration in its river systems as a consequence of rapid economic growth, particularly in the oil and coal-mining industries. The project area is located in the drainage basin of the middle reaches of the Yellow River. The surface water system is mainly consisted of three rivers, namely the Yellow River, Yan River and Qingjian River. The segment of the Yellow River in Yan’an municipality is 183 km with an annual mean runoff 28.87 billion m3 at Yanshuiguan section. Yan River and Qingjian River are the first class tributaries of the Yellow River with an annual mean runoff 282 million m3 and 163 million m3, respectively. Water supply in the Yan’an Municipality is at present based on two water sources, i.e., municipal waterworks system and private groundwater wells. The municipal water waterworks abstracts about 50,000 m3 per day from the Wangyao and Hongzhuang reservoirs on the Yan River. While Beiguan Waterworks, as a supplementary source, abstract about 30,000 m3 per day from the Yan River and Xichuan River directly. However, the supply of Beiguan Waterworks is not reliable because of the fluctuation of runoff in the two rivers. 5.2 Environmental Quality Surface Water Routine monitoring data indicated that water quality in sections of mentioned rivers within the project area ranges from Class Ⅲ to Class Ⅴ against the Chinese National Environmental Quality Standard for Surface Water (GB3838�2002). Specifically, water quality in Yan River is satisfied with the standards of Class Ⅳ, while water quality in Qingjian River is barely reaches the standards of Class Ⅴ, with exceeding of oil, volatile phenolic compounds, COD, total phosphate, and ammonia nitrogen. 7 However, water quality in the Yellow River is between Class Ⅱ and Ⅲ, which is the target objective1 of the surface water protection. Fortunately, the monitoring data shows a trend that water quality at the sections of the above rivers is improving with the enforcement of the national and local emission standards. Ground Water Based on a survey in 2005, 11 of 26 ground water sources in Yan’an was in compliance with Class III of the Chinese National Environmental Quality Standard for Ground Water (GB/T14848-93) and water quality from the other 15 wells satisfied with the standards of Class Ⅳ or worse. According to this standard (GB/T14848-93), only water with Class III quality I can be used for centralized drinking water supply, and industrial and agricultural uses. Acoustic Environment To assess the acoustic environment, a two-day continuous acoustic environment monitoring was conducted during June 2009 at three locations along the project alignment. The monitoring results of equivalent A-weighted sound pressure level (Leq) indicate that the acoustic environment was pretty good, with no point (during day or night) exceeding Class 2 of the Chinese National Environmental Quality Standard for Acoustic Environment (GB3096-2008). Ambient Air Ambient air quality monitoring was carried out as part of the EIA. Concentration of sulfur dioxide (SO2), nitrogen dioxide (NO2), and total suspended particulate (TSP) was monitored at two stations in the PA for five successive days during June 2009. Results indicate that air quality was in compliance with Grade 2 of the Chinese National Environmental Quality Standard for Ambient Air (GB3095-1996), except TSP exceeded the same standard slightly at both monitoring stations. The TSP exceeding may relate to the local dry and windy weather in couple with the mediocre vegetation. 5.3 Ecological Environment Terrestrial Ecology Based on a terrestrial ecological survey conducted in 2009, there are no natural reserves in the project area. The land that will be requisitioned or temporarily occupied by the project is mainly farming land or uncultivated land. Vegetation is dominated by farming crops, grasses and bushes. Some secondary forest on the south bank of Yan River was replanted in 1970s. The survey reported that there are 596 plant species in 323 genus and 93 families. Other findings included 117 vertebrate species (in 4 classes 23 orders and 49 families), including 2 species of amphibians, 7 species of reptiles, 89 species of birds and 19 species of mammals. However, none of this species are considered endangered, rare or protected. Aquatic Ecology 1 The protection objectives of the sections of the mentioned rivers in the project area have been established as equivalent to Class III of GB3838�2002 by the Surface Water Function Zoning in Shaanxi in 2004. 8 A dedicated survey was conducted by Shaanxi Fisheries Research Institute in 2009. The results indicated that aquatic flora and fauna communities in the water bodies of Yan River, Qingjian River are relatively simple. There is almost no fish in the two rivers because of degradation of water quality and runoff decreasing in recent years. In the Yellow River, however, the survey revealed that there are 87 species of phytoplankton with an average biomass of 0.093 mg/l, and 42 species of zooplankton with an average biomass of 0.1452 mg/l. It is also found 14 species of benthic organisms. The historical record shows that there were about 20 fish species in the middle reaches of the Yellow River, including 5 endemic species of the Yellow River. Unfortunately, the fish species have been decreasing in Wangjiaqu section (intake) in recent years due to the construction of the upstream Tianqiao Hydro (dam) and the downstream Sanmenxia Dam in the 70's and 60's, respectively. The survey also concluded that none of the fish species is in the first or second class of the national or provincial protection list. Soil Erosion The project area is the most severe soil erosion area in the province and one of the major sediment contributors to the Yellow River. A total of 4,256 km2 of land, accounted for 75% of the territory of Baota District and Yanchuan County, is suffering soil erosion with an average erosion modulus of 12,000 t/km2 a. The main causes of the bad soil erosion in the region are the characteristics of loess plateau with fragile ecosystem, plus the extensive agricultural and industrial development. Fortunately, the trend of soil erosion is slowed down and the ecosystem is gradually improving in the last decade due to a series of effective measures taken by the government, including the grain-for-green policy and implementation of the World Bank loan project for Loess Plateau Watershed Rehabilitation Project2 which focuses on water and soil conservation while increasing agricultural production and income. 5.4 Socio-Economic Situation The project city of Yan’an is a medium-size city in northern Shaanxi Province, rich in oil and coal resources and of national strategic importance as an energy production base. Yan'an is a historical, rapidly growing prefecture-level city located on the Loess Plateau, administering thirteen counties in addition to the core city.3 The World Bank financed portion of the YWSP lies in Baota District and Yanchuan County. The socio-economic situation of the project area is summarized in Table 4. Table 4 Socio-economic Situation of the Project Area County Unit Yan’an Municipality Baota District Yanchuan County Item 4 2 Total area 10 km 370.37 35.56 19.85 Township/town Nr 166 23 17 Rural village Nr 3,391 631 346 On May 20, 2004, Loess Plateau Watershed Rehabilitation Project was gained the World Bank group president’s awards 2 for excellence 2003 which chose from 3105 projects 3 The current population of Yan’an municipality is estimated to about 2.15 million, of which about 0.5 million reside in Yan’an City. 9 4 Total population 10 people 215 45 18.7 4 Rural population 10 people 153.46 22.06 14.5 2 Arable land km 312,000 34,600 24,400 Per-capita arable Mu 2.20 2.36 2.55 4 Total grain output 10 ton 82.04 8 Agricultural output 10 Yuan 51.99 7.24 2.13 Farmer’s per-capita net Yuan 4,845 4,147 3,279 income 8 GDP 10 Yuan 885.4 125.2 44.3 5.5 Sensitive Sites During the EIA process, environmentally sensitive sites in the project area were identified and analyzed. There is no natural habitat and other environmentally sensitive sites within the project area and all the significant historic and cultural relics are far from the project sites. Main environmental concern will be the fish species in the Yellow River. Necessary protective and mitigation measures will be taken in the intake facility engineering. 6. Analysis of Alternatives The project has been subject to intense analysis of alternative options including the project-no project scenarios, and various options for the water supply sources, water transfer line alignments, reservoir sites, technologies in the Dongchuan WTP, as well as the arrangement of borrow pits, and the transportation plan for construction. The optimal alternatives were selected based on the avoidance of or possibility to mitigate adverse social and environment impacts, as well as other economic, technical, and financial considerations for the least cost solutions. 6.1 With and Without-Project Analysis With and without-project analysis is conducted based on socio-economic benefits and potential positive and negative environmental impacts. Under the “without-project� scenario, there will be continuous threats to production and living standards of the local people and retarded economic and social development in Yan’an, since the conflict between water supply and demand and environmental deterioration in the region are becoming increasingly serious. On the other hand, the “with-project� scenario will generate long-lasting social and economic benefits, while the environmental impacts, mainly during construction period and thus temporary, can be avoided or mitigated by using well known environmental protection measures. Environmental benefits clearly outweigh environmental impacts. 6.2 Alternative Analyses of Water Supply Sources Five water supply sources were considered, including supply water from Yan River, Qingjian River, Beiluo River, the Yellow River and groundwater. These sources were compared according to a wide 10 range of factors such as water quantity, quality, construction conditions, resettlement, environmental impacts, sustainability, and total investment. Abstracting water from the Yellow River at Wangjiaqu in Yanchuan County is the best choice. 6.3 Alternative Analyses of Water Transfer Alignments The water transfer is consisted of two parts, i.e., the Yellow River-Gaojiawan (Domestic fund), Gaojiawan – Yan’an (the WB fund). Two alternative alignments for each part of the water transfer line were developed and evaluated, in terms of section alignments, length, arrangement of tunnels, construction and maintenance costs, to recommend the most economically, socially, and environmentally sound alignments. 6.4 Alternative Analyses of Dam Sites and Structures This project involved two dams. One locates downstream, in Baishugua, for regulating and another located upstream, in Kangjiagou, for emergency and maintenance backup. In principle, the initial sites of the two dams are satisfying with the project design concept. In order to optimize the design and construction, two alternative sites and dam structure were examined and analyzed. The final sites of the two dams were selected according to a number of considerations including topography, engineering geology, construction conditions, quantities of earth and stone works, land occupation, inundation damages, resettlement, environmental impacts, and total investments. Given the locally available construction material, the structure of the dams was narrowed down to masonry gravity dam and earth-fill dam. Since the later structure is widely used in Yan’an and the loess plateau area, it would be used for construction of both dams. 6.5 Alternative Analyses of Water Treatment Process The site of the Dongchuan WTP has been sound decided during the feasibility study considering its closeness to the water pipeline, topographical, geological conditions, and environmental settings. During the EIA, the focus of alternative analysis was given to the ground layout, in terms of land requisition, and water treatment process in the Dongchuan WTP. As a result, a staging land requisition plan and integrated water treatment technology, including zero wastewater discharge and sludge disposal were developed. 6.6 Access Roads Optimization No doubt, the existing state highway G210, provincial highway S201 and many local roads will provide great convenience to the project. However, optimization of infield construction roads was one of the EIA objectives. The following principles were applied in the alternative analysis.1) maximize the use of existing roads; 2) integrate temporary construction roads with the permanent pipeline maintenance roads; 3) minimize new road and temporary roads; 4) minimize land occupation and side slope excavation; 5) design roads with considerations to accommodate the construction traffic. Among the infield roads optimization, reduction in access roads to Yangjiashan Tunnel construction sites was significant. Table 5 shows the details. 11 Table 5 Infield Road Plan Optimization from Feasibility Study (FS) to Preliminary Design Stage Stage FS Stage PD Stage Comment Infield roads, km New roads to be 55.3 36.44 To pipeline constructed Road to be rehabilitated 20 20.38 Due to the use of existing road Use of existing road 75.2 95.80 st nd and road rehabilitation, new road New roads to 1 and 2 3.60 3.60 construction was substantially pump stations To pump stations and reduced rd th New roads to 3 to 6 pump , resulting in a reduction in earth 0.61 0.32 reservoirs stations and stone works and number of New roads to Dongchuan spoil disposal site, and land 0.29 0.25 WTP occupation. Ultimately, the environmental footprint of the New roads to two reservoirs 2.0 1.5 project is minimized. Temporary infield roads 3.5 3.0 New roads to be constructed To YJS 7.0 2.74 Tunnel Road to be rehabilitated 5.43 9.05 4 6.7 Optimization of Spoil Disposal Sites It is estimated that about a total of 316,000 m3 of spoil needs to be disposal. Two third of the spoil will be generated from the tunnel construction. The Yangjiashan tunnel will alone produce 107,800 m3 of waste. Spoil disposal sites have been optimized in many ways such as the total number and distribution, site capacity, location and transportation distance as well as environmental impact to the surrounding ecosystem. 7. Environmental Impacts and Mitigation Measures 7.1 Impacts during Construction and Mitigation Measures Project construction will have a temporary impact on the surrounding environment. Typical short-term construction impacts include those on the river water regime, ecological environment, soil erosion, water quality, air quality, noise, and solid waste. If properly planned, construction impacts on the natural environment can be minimized to an acceptable level. Water Environment Hydrological regime The construction of the project will involve several inverted siphons when crossing Yan River and Wenanyichuan River. It is suggested to schedule the constructing of cofferdam during Nov-Mar (dry season) so that the impact to the river hydrological regime can be reduced to an acceptable level. Yang-Jia-Shan tunnel, 11.34 km, is part of the water transfer line between the intake at the Yellow River and Gaojiawan 4 pump station. The tunnel will be built by using the government fund. 12 Water quality The impact of wastewater from the construction sites and construction camps on the water quality of the rivers and streams, as well as the impacts of siphon and tunnel construction on ground water were also assessed. It was found that the limited impact on the water environment during construction can be mitigated by several measures, including installing sedimentation tank to each of the construction material process sites, concrete mixing sites, applying water recycling and reusing, installing small oil-separation tanks at vehicles and equipment maintenance stations, and providing dry latrines at construction camps. Special attention was paid to the cleanup of the new Kangjiagou reservoir. An agreement between the Qinghuabian Oil Field and YWIC has been reached on capping 29 oil wells which located in the site of the proposed Kanjiagou reservoir. The 29 oil wells will be capped in two stages and the inactivation of the wells will follow the guidance of Well Abandonment and Inactive Well Practice (SY/T 6646-2006)5. Prior to storage water, the reservoir will be throughout cleaned up according to the requirements specified in the Design Specifications for Cleaning of Reservoir Zone of Hydroelectric Project (DL/T 5381-2007)6. Ecological Environment Potential impacts on terrestrial ecology during construction would be mainly on agricultural ecosystems, including crops vegetation, fruit trees, secondary forests, and grass land. The impact also include disturbance of some small terrestrial animals and birds. Such impact will be temporary and can be mitigated or minimized by the implementation of well planned and budgeted soil conservation measures at all construction sites. The recovery of farming crops and local indigenous vegetations are expected after construction. Potential construction impacts on aquatic ecology in Yan River and Qingjian River are also not expected to be significant as no aquatic plants or animal species with a high economic value or ecological protection status were identified. However, the construction of intake facility in the Yellow River at Wangjiaqu would disturb some fish species. The mitigation measures include minimizing construction activities in the river course and scheduling the construction in dry season. The impact of the construction on fish is not expected to be significant because most of the construction activity would be on the shore and construction activity in the river will be very limited and would not last long. Social Environment Social impact during construction will include the impact on local traffic, infrastructure, and public health. Although the EIA concluded that the construction impact to the downstream Yellow River Meanders National Geopark will be negligible, some impact, during construction phase, to the local infrastructure will be inevitable, including impact on roads and wire poles, communication cables, utility lines and natural gas transmission pipelines. The construction impact on local traffic will be mitigated by (1) build new alternative roads prior to the construction to compensate the damage and loss; (2) strengthen traffic management of the affected areas, including scheduling construction 5 National Development and Reform Commission of the PRC, July 10, 2006 6 National Development and Reform Commission of the PRC, July 20, 2007 13 traffic to avoid busy roads and rush hours, placing safety warning signs and detour maps, and preparing traffic emergency preparedness plans. Regarding the potential impact to the natural gas transmission pipeline, the construction activity will strictly follow the required specifications provided by the West-East Gas Pipeline Company to secure the safe operation of the gas pipeline. To ensure construction workers’ and local people’s health during construction, the EIA recommends epidemic prevention measures to strengthen food safety, and to increase public health awareness. Air Environment During the construction, explosions, excavations, backfilling, sand and stone processing, concrete stirring, the movement of construction vehicles and the handling of materials will all generate air-borne dust. Dust resulted from explosions will be within a range of 100 m referring to the experience in the similar operations. Tail gas emissions from construction machines and vehicles are also predicted. The impact of air-borne dust will be limited to local residents and the construction workers. Dust impacts will also disappear with the completion of construction. Mitigation measures for dust and emission control include selection of sound explosive technology to control air-borne dust at its sources, placing dust removal devices on concrete mixers, and delivering cement by closed vehicles, regularly watering the construction sites and roads, installing ventilation systems for tunnel construction, providing protective devices (such as masks) to construction workers, regularly checking and maintaining the construction vehicles and machineries to ensure emission are compliance with the national standards. Acoustic Environment Noise from construction activities will potentially affect nearby residents and construction workers. Based on a quantitative analysis of noise attenuation with distance, the sensitive spots and affected time periods were identified and analyzed. Accordingly, appropriate mitigation and protective measures were developed and recommended to the concern parties. Impact of Solid Waste A total of 316,000 m3 of construction spoils and 570 tons of domestic waste will be generated during the construction phase. A total of 16 disposal sites have been arranged and optimized for disposal of construction spoils. Soil conservation measures will be applied to control soil erosion at these sites. In respect of domestic waste, garbage bins will be provided to the construction sites and campus for collecting and sorting. Food waste will be used for livestock or composting. Organic solids waste will be collected and disposed in the local municipal landfill sites. Inorganic waste will be disposed in the nearby spoil disposal sites. 7.2 Impacts during Operation and Mitigation Measures During operation stage, the YWSP will impact Yan’an and its vicinity environmentally and socially. However, the positive impact will be much more significant than its negative impact. In addition, many of the negative environmental impact can be reduced to an acceptable level with the implementation of environment management plan (EMP). 14 Water Environment The impact of proposed project on the water environment includes two aspects, hydrological regime and water quality. Change of hydrological regime usually cause by flow pattern and/or runoff fluctuation. The proposed intake facility is an onshore stationary pump station with no any cofferdam and other obstacle in the river. Therefore, the project has no change to the original watercourse of the Yellow River. In respect of runoff change, the Water Resources Study Report7 conducted an intensive analysis and concluded that, the volume of the water, 56.83 million m3/a, extracted by the project in 2030, that will be reach the objective volume, accounts for 0.21% of the annual average runoff (27.53 billion m3/a), or 0.43% of dry year runoff (13.19 billion m3/a at 95% confidence) at Yanshuiguan section of the Yellow River. Therefore, the project has little impact on the hydrological regime of this section in the Yellow River. It is also anticipated that a total of 23.06 million m3 return water will be discharge to Yan River by the objective year 2030. Comparing to the total runoff (282 million m3/a) of this segment of Yan River, the return water is about 8.2 % of the runoff of Yan River. The impact of returning water to the hydrological regime of the surface water is limited. In opposite, the local surface water system may benefit from the return water, especially in dry seasons. Return water are combination of domestic sewage and industrial wastewater, containing BOD5, COD, NH3-N, oil and volatile phenolic compounds, and has potential impact on surface water and aquatic environment. Two strategic measures will address this threat. One is enhancement of the Energy Saving and Emission Reducing policy across all industrials to make sure the industrial discharge is meet the requirements of the national standard. Another is increase wastewater treatment capacity. According to the YMG plan, the city’s wastewater treatment capacity will be increased to150, 000 m3/d by 2015 from 50,000 m3/d at present. Ecological Environment As mentioned above, the quantity of water to be extracted from the Yellow River, during operation phase, is relatively small comparing to the runoff in the river. Therefore, it is not expected to bring a significant impact on the fish in the river. In addition, a protective fence with 1×1 cm mesh will be installed around the intake to prevent the loss of fish in the river. Despite this, an ecological base flow of 100 m3/s has been defined to maintain the river health and ecological functions. It is agreed that extraction of water from the Yellow River must be stopped and switch to using the reservoir water whenever the flow at this section of the Yellow River is smaller than 100m3/s. According to the Yan’an Government plan, once the YWSP is in operation some of the groundwater wells will be capped and water demanding from the Yan River for industrials use will be reduced. As a result, the groundwater regime and agriculture ecology will be improved gradually. 7.3 Safety of Dams The project will finance construction of a regulating and emergency reservoir/dam at Kangjiagou (42m high earthfill dam, reservoir capacity: 1.55MCM). Another reservoir/dam of similar function at Baishugua near the water intake (59m high earthfill dam; reservoir capacity: 5.56MCM) is also to be Yellow River Engineering Consulting Co. Ltd., 2011, Water Resources Study Report of YWSP 7 15 built as part of the complementary works (to be financed with government funds) ahead of the Bank project. In addition, two existing reservoirs/dams, Wangyao (55m high earthfill dam, reservoir capacity: 203MCM) and Hongzhuang (50.2m high earthfill dam, reservoir capacity: 9.79MCM) supply water to the existing service areas of Yan’an city (Baota District). All the above-mentioned dams are owned by YWIC. A dam safety panel (DSP) was established by Yan’an PMO with terms and conditions satisfactory to the Bank. A dam safety review report was prepared by the DSP for the two existing dams, Wangyao and Hongzhuang, and the two new dams, Kangjiagou and Baishuwua, both of which were reviewed by the Bank team during pre-appraisal mission. An updated report on the results of dam safety review for Wangyao and Hongzhuang dams, and on the feasibility study review (incl. dam safety plans) for Kangjiagou and Baishuwua dams, incorporating Bank’s comments, will be prepared. The YWIC with assistance of its consultants will prepare Operation, Maintenance and Surveillance Plans (OMS Plans/Manuals) and Emergency Preparedness Plans (EPPs), which will be furnished to the Bank for review a year ahead of the dam commissioning time. During project implementation, qualified contracts will be contracted for the dam construction, and competent consultants will be engaged to supervise the dam construction. 7.4 Cumulative Impacts Linked Project An overview of the linked project is presented in Table 6.

During the Construction in 1997 and first several years, it In the projects To be completed in Hongzhuang Reservoir runs with a capacity Duration 3 preparation stage 2016 was built in 2005 as a less than 28,000 m /d. supplementary water Now, it is running with source full capacity., 16 Water Resources Analysis The Water Resources Study Report, by the Yellow River Engineering Consulting Co. Ltd, conducted an intensive analysis of total water balance. The study shown that the target abstraction volume of 56.83 million m3/a, which includes the water supply to Yanchuan County and Qingjian County in 2030, accounts for 0.21% of the annual average runoff (27.53 billion m3/a), or 0.43% of dry year runoff (13.19 billion m3/a at 95% confidence) at Yanhuiguan section of the Yellow River. Based on the analysis, the project will have little impact on the hydrological regime of this section in the Yellow River. Impact on Water Quality It is estimated that an additional 23.06 million tons of domestic sewage and industrial waste water will be added to the existing 10 million tons of wastewater annually. However, the wastewater treatment capacity in Yan’an is only 50,000 tons per day (≈16.5 million tons per year) at present, although the city government has forecasted this issue and planned to build two more new WWTPs in Yan’an with an additional capacity of 100,000 tons per day. Feasibility studies of the new WWTP projects are in progress. Impact on Eco-Environment Water transfer pipeline is built under ground; therefore, its impacts on the eco-environment are, occurring during construction, minor and temporary. Baishuguan reservoir and Kangjiagou reservoir will be built at two small tributaries of Qingjianhe River and Yanhe River, respectively. The two tributary are small intermittent with no fish. In contrast, the two reservoirs will create additional water surface in the project area and a mini humid environment, which will benefit amphibians, birds, macrophytes and fish. The project will be beneficial for the local eco-environment. Impact on Social Environment Although the YWSP involves some involuntary resettlement, the two reservoirs will inundate certain areas, which bring some negative social impact, the entire project will generate significant socio-economic benefit to Yan’an and northen Shaanxi Province. The annual income from water supply, 27.77 m3/a by 2030, will be 350 million RMB. Given the total 139.38 million RMB in environmental loss in cash (13.04 m RMB for environmental protection, 26.39 m RMB for soil and water conservation, and 99.95 m RMB for land acquisition), the benefit/loss ratio is 2.5:1. Most importantly, the increased water supply and expanded coverage for Yan’an City will greatly improve people’s standards of living and solve the bottleneck of industrial development, in turn, create more employment opportunity in the region, provide a health infrastructure for Yan’an’s sustainable development. 8. Environmental Management Plan The EIA report of YWSP recommends the implementation of an Environmental Management Plan (EMP). The EMP proposes a number of measures to mitigate environmental impacts during the 17 construction and operation of the proposed project and establishes an organizational structure, set of procedures and a budget to implement activities under the EMP. The EMP has also identified a set of environmental monitoring activities, water & soil conservation monitoring activities, and capacity building programs to ensure achievement of the project’s environmental objectives. The EMP addresses all issues identified in the EIA, and includes a detailed description of all activities, the institutional responsibilities for implementation, and defines a budget and source of financing for each one of the activities included in the EMP. Most mitigation measures have already been included in project design and included in project costs. Main components of the EMP include: � Environmental management system. � Environmental management capacity building and training � Management of construction impacts � Environmental monitoring, and water & soil conservation monitoring � Resettlement Action Plan � Budget for environmental management � EMP reporting and information management Clear environment management responsibilities have been defined for both construction and operation of the YWSP. Environmental management must be available throughout the construction and operational periods whereby there will emerge many factors that will have impacts on the environment. Therefore, the project will establish professional administrative institutions and equipped with necessary environmental protection personnel, being responsible for carrying out and supervising the work of environmental protection of the project. 18 Provincial level YWSP Steering Committee City level The World Bank YWSP Leading Group Yan’an Water Investment Company Project Management Office Design Institute Project Safeguards Section Project level EA consultant Institution Envi. Monitoring Agency Envi. Supervision Contractors Figure 3 Environmental management system of YWSP To ensure the implementation of the EMP, a qualified professional environmental supervision agency will be hired and working onsite to monitor the implementation of mitigation measures, and reporting to PMO, local EPBs and the World Bank. Comprehensive environmental monitoring programs have been designed for both construction and operation phases of the project. Monitoring includes water quality, air quality, noise, public health, ecology, as well as erosion of the PA. Monitoring will be conducted by qualified professional agencies. After trial operation, environmental monitoring and erosion monitoring will be carried out by provincial and Yan’an municipal environmental protection bureaus, and water conservancy bureaus, respectively. All personnel of the Project Office Safeguards Section and construction workers will receive environmental protection training before commencement of construction. Key environmental administrative and monitoring personnel will also receive the technical training. The main issues addressed in the EMP are presented in the following Table 7. 19 Table 7 Main Mitigation Measures and Responsibility in EMP Impact Mitigation Responsibility A detailed set of environmental specifications including a soil and water conservation plan will be General Contractor, enforced by included in all bidding documents and contracts; construction Environmental Supervision Environmental training and technical consultation impacts Consultant and PMO/YWAB will be provided to the contractors; Environmental Supervision Consultant will be hired. The part of the 19.2 km government financed work, including 11.36 km long Yanjiashan Tunnel, will be Construction work follow the same standards/requirements specified in Contractor, enforced by financed by the the EMP. A special clause will be included into the Environmental Supervision Government contracts as contract variations, that is, the Consultant and PMO/YWAB contractors must comply with all the environmental safeguard requirements of the EIA/EMP. Construction of the two reservoirs will strictly follow the specification/requirements developed by the Dam Safety Expert Panel according to the bank Contractor, owners of the oil policy of Safety of Dams (OP/BP 4.37). In additional, wells, enforced by Reservoir the construction activities will obey the general Environmental Supervision Construction environmental specifications including a soil and Consultant and PMO/YWAB water conservation plan. In particular, capping the with support of YMG 29 oil wells in Kangjiagou site must follow the guidance of Well Abandonment and Inactive Well Practice (SY/T 6646-2006). To minimized the impact on water resources and fish species in the Yellow River, a ecological base 3 flow, 100 m /s, has been established for the Wangjiaqu section of the Yellow River, the project Water resources will stop diverting raw water from Wanjiaqu water YWSP, Yellow River and fish species intake of the Yellow River at any time when the flow Conservancy Commission 3 is less than 100 m /s. As an engineering measure, a protective grid of 1×1cm mesh will be installed around the intake to keep fish away from the pump intake. Relocation of Resettlement Action Plan PMO of YWSP Population 20 9. Resettlement Action Plan To achieve its objectives, the project envisages abstracting Yellow River water and building the associated works (pipes, tunnels, water treatment plant, and reservoirs) to transfer water to Yan’an city. While bringing benefits to local populations, these project activities would also cause some land acquisition and involuntary resettlement of local community. The project social assessment (SA) was first carried out in Dec 2008, and a supplementary survey was carried out in Jun 2011. The survey covers 45 villages in 7 townships that may be affected by the project, and the result is illustrated in Table 8 below. Based on fully informed and extensive consultation among these communities, the SA proved a broad support of local communities to the project and this led to a Resettlement Action Plan (RAP). Since the Bank supported project is an integral part of the YWSP as a whole, the RAP also contains the resettlement contents of the overall YWSP. Appropriate and practicable measures were planned for compensation and rehabilitation of the affected peoples’ livelihoods, as agreed and satisfied by them. Policies and entitlements included in the RAP are based on national, provincial and municipal regulations, as well as requirements in the World Bank’s OP 4.12. The following key considerations were applied in project planning and design and in RAP preparation:  Minimizing the extent of land acquisition and resettlement by optimizing project design, and minimizing the impact to the local communities if land occupation and resettlement is inevitable.  Surveying socio-economic baseline conditions, and identifying all displaced persons (DP) in households, enterprises and others at the project preparation stage.  Determining compensation for land, structures, and other fixed assets at replacement cost, and guarantee their incomes and living standards can be improved or at least restored.  Providing assistance to help the displaced people diversifying incomes avenues and improving their livelihoods.  Consulting with displaced persons on arrangements for compensation and assistance.  Establishing mechanism to address complaints and grievances for the displaced persons including discussions, negotiations, arbitration, and legal proceedings.  Arranging supervision and monitoring to ensure the RAP compliance and to address other issues that may arise during RAP implementation 21 Table 8 Details of Resettlement Surveyed Project Yellow River (intake) – Gaojiawan Pump Station Gaojiawan Pump Station – Dongchun WTP included sections (Government fund, 19.20km) (The World Bank loan, 63.78km) Land Dry Dry Greenhouses Orchard Residence Temporary Dry Dry slope Greenhouses Orchard Residence Temporary Total Occupation flat land slope land land occupy flat land land land 0 occupy (mu) 71.13 62.87 0 133.99 3.3 288 8.1 92.86 17.4 25 1423.8 Subtotal Acquisition Area:271.29 Subtotal Acquisition Area :143.36 Temporary occupy:2126.45 acquisition :414.65 Affected Five villages: Fengjiayan, Yanshuiguan, Baishugua, Gaojiawan, Zhangjiahe Four villages: Gaojiagetu, Xiuejiagou, Kangjiagou, Yaodianzi 9 villages Total population: 3151, Total household: 685 Total population: 2636, Total household: 570 Population Affected by land: Affected by residence: Affected by land: Affected by residence: Total affected 455 persons 70 persons 355 persons 0 population: 814 99 households 12 households 77 households Affected household:177 Building Brick/ concrete: Brick/wood Stone cave Earth cave Brick/ concrete : Brick/wood : Stone cave Earth cave 2130 m2 demolition 290 60 (㎡/number) (㎡number) 0 0 (㎡/number): (㎡/umber): 1110/37 220/8 450/15 0 Subtotal:1,680 m2 Subtotal:450 m2 Ground Fruit tree Lumber tree Young tree Nursery Fruit tree Lumber tree Young tree Nursery objects (No.) (No) (mu) (mu) (No.) (No) (mu) (mu) 7360 4136 272.05 3.1 18266 5985 1692.11 27.9 Infrastructure Oil well Wire Communic Power Paved road Unpaved Oil well Wire Communic Power Paved road Unpaved road (No) (km) ation cable cable (km) road (No) (km) ation cable cable (km) (km) (km) (km) (km) (km) (km) 0 1.5 1 1.1 0 0 29 8.5 6.5 7 1 3 Affiliated Cook stove Heating Cellar poultry Pens Toilet Cook stove Heating Cellar poultry Pens Toilet Buildings (No) bed (No) house (㎡) (㎡) (No) bed (No) house (㎡) (㎡) ( No) (No) ( No) (No) 15 25 8 10 50 25 0 0 0 0 0 0 22 10. Public Consultation and Information Disclosure A variety of ways of public participation, including questionnaires, public announcement, public meetings in the township government, village committee and affected villagers’ homes, as well as meetings with key stakeholders, have been implemented during preparation of the EIA and Resettlement Action Plan. Each mitigation measure was determined by suggestions from both experts and the public. Most of the concerns have been incorporated either in project design, project management or in the environmental management plan or resettlement plan. Two-stage public consultations have been conducted with those affected by the proposed project and included persons from different groups, gender, socioeconomic and educational backgrounds, and occupations. The primary objective of the first round was to survey the public’s opinion about the project, while that for the second was to communicate the EA findings, discuss intended mitigation measures, and confirm public acceptance and satisfaction. In addition, there have been several rounds of consultations with government agencies, local governments, and other stakeholders to discuss site location, scope, and potential environmental and socioeconomic impacts of the proposed project. On the top of that, intensive consultations have been conducted with Yanchang Oil Company, the West-East Gas Pipeline Company and Land and Resources Bureau of Yanchuan County for the potential impact on oilfield in the site for proposed Kangjiagou reservoir, natural gas pipeline and the Yellow River Meanders National Geopark, respectively. All the stakeholders have well informed about the project impact and expressed their understanding and support; together some constructive solutions have been worked out. Information about the project has been disclosed through major local newspapers, Yan’an Daily on Nov 8, 2011. Telephone hotline has been established for the public to access relevant documents and offer comments. The EA/ EMP/EA Summary, and RAP will be available at the PMO and Project owner. The reports will also be disclosed at the website of the Bank’s Beijing office and at the Infoshop in Washington, DC. 11. Conclusions The project city of Yan’an is the political, economic and cultural center of northern Shaanxi, rich in oil and coal resources and of national strategic importance as an energy production base. However, Yan’an has suffered from water shortage for many decades, because of limited water resources on the Loess Plateau, outdated infrastructure, and increasing water demand caused by rapidly population growth and industrial development. The World Bank financed YWSP is essential to safe water supply for Yan’an. The project implementation will substantially relieve the tension between severe water demand and water supply. It is the most critical and effective measure to resolve the 23 water crisis in the region, improve people's standard of living, and ensure sustainable development in Yan'an. After the completion of YWSP, many groundwater supplies will be gradually closed and the trend of over-exploitation in groundwater will be reduced. It will beneficial to groundwater resources recovery and protection. Meanwhile, the increased water supply will produce a volume of return water of about 23.06 million m3 annually, which will be treated to be compliant with the national discharged standards and returned to the surface water system. The treated return water is useful for maintaining an ecological base flow in the Yan River, which has been seriously polluted by the domestic and industrial discharges. Therefore, the project will also improve the local aquatic environment and ecosystem. The adverse impacts on the eco-environment and soil erosion during the construction phase are considered minimum, and will further be reduced and mitigated to an acceptable level by taking environmental friendly measures. The Environmental Assessment concludes that the YWSP will not affect the environment and the project construction will be environmentally feasible. 24
