Preface

P.R.China Sichuan Wudu Irrigated Agricultural Development Project (WIADP) is composed by Xizi canal, Jinfeng Reservoir, 17 branches (sub-branch), three CDD-based on-farm demonstration areas, institutional capacity building and project management, which is also named as Sichuan Wudu Second Phase Irrigation Scheme (Wudu Phase II Irrigation Scheme).

The World Bank financed WIADP includes 12 canals in Mianyang prefecture under Wudu Phase II Irrigation Scheme, three CDD-based on-farm demonstration areas, institutional capacity building and project management. The 12 canals include the first section of Xizi main canal (23.191 km in length), a branch canal (Jinlong branch) and 10 branch (sub-branch) canals (right branch canal of directly irrigated area of Wudu reservoir, Yongzhong branch canal, Yongdong branch canal, Dabao branch canal, Zenbo branch canal, Yunashan branch canal, Shihei branch canal, Fucheng branch canal, Linma branch canal, Jinxi branch canal). The length of all the branch canals is 258.503km and the irrigated area is 870700mu which covers Jingyou, Yanting and Zhitong counties. The development tasks of the World Bank financed Wudu Irrigated Agricultural Development Project (WIADP) are agricultural irrigation, domestically and industry water supply. WIADP plans to apply US$100 million (RMB 680 million) for part invest of the civil engineering, construction of three CDD-based on-farm demonstration areas, institutional capacity building and project management.

Government fully financed part of WAIDP comprises the second to the ninth section of Xizi main canal, Jinfeng reservoir, 6 branch (sub-branch) canals (left branch canal of directly irrigated area of Wudu reservoir, Guangzhong branch canal, Renxing branch, Wenxing branch, Gongtuo branch and Huilong branch), Jinlong branch canal and Yunashan branch canal located outside of Mianyang prefecture. The total length of the canals is 199.368km and the irrigation area is 252,500mu in 6 counties of 4 cities, that is Jiangyou, Yanting, Tongzi in Mianyang city and Sheyuan in Shuining city, Yange in Guangyuan city and south part of Nancong city. The development tasks of government financed Wudu Irrigated Agricultural Development Project (WIADP) are agriculture irrigation, domestically and industry water supply.

World Bank-financed WAIDP is an important component of Wudu Water Diversion Scheme, which is a large-scale water project constructed in the middle and up stream of Fujiang river and mainly for agricultural irrigation as well as power generation, flood protection and urban water supply. Wudu Water Diversion Scheme has been constructed in two phases. Phase I mainly included sluice water diversion project and Fuzi Irrigation Scheme which has been constructed since the end of2004 and planed to completed in 2010. "Feasibility Report of Wudu Phase II Water Diversion and Irrigation Scheme" was compiled by two organizations, Sichuan Water Resources and Hydropower Survey, Design and Research Institute and Mianyang Water Resources Planning and Design Institute, in December 2009.

Irrigated areas under Wudu Phase II Irrigation Scheme are an important food and edible oil production base in Sichuan province and Mianyang City. Water quantity and water source can't up to the standard for long time because of uneven rainfall distribution in space and time and so as to cause extreme harm to the agricultural production and economy, even

limit the economic development in the irrigation region. Wudu Irrigation Phase II Project could satisfY the basic requirement of the safety water supply, with insurance of the food safety and social stability. It is an important measure to construct "new food granary" of northwest Sichuan and speed the re-building ofWenchuan after big earthquake.

National Development and Reform Commission approved the proposal of WIADP on Oct.9, 2009 (No. [2009J2504). "Feasibility Research Report for Sichuan Wudu Phase II Water Diversion Project" passed the technical review organized by Institute of Water Resources and Hydropower Planning and Design, Ministry of Water Resources (MWR) in February 20 I O. Water Source Study Report of Sichuan Wudu Phase II Water Diversion & Irrigation Scheme prepared by MWR and Hydropower Survey and Design Institute of Sichuan in April 2010 passed the technical review Organized by Wuhan Changjiang Water Resources Commission, Ministry of Water Resources in July 20 I O. Water and Soil Conservation Program of Sichuan Wudu Phase II Irrigation Scheme prepared by the Sichuan Water Resources and Hydropower Survey, Design and Research Institute ofMWR and passed the technical review organized by Institute of Water Resources and Hydropower Planning and Design, MWR in February 2010. "Environmental Impact Assessment of Wudu Phase II Irrigation Scheme" (EIA) was prepared by Chengdu Investigation, Design & Research Institute of China Hydropower Consulting Group in Jan. 2010, which has passed the pre-check organized by the Institute of Water Resources and Hydropower Planning and Design of MWR in February 2010 and is waiting for the approval of Ministry of Environmental Protection. During the EIA of phase II project, Chengdu Institute of Biology, Chinese Academy of Sciences, Fisheries Research Institute in Sichuan Province were delegated to develop investigation and assessment of terrestrial, aquatic ecology in the project region. Various public participation activities were carried out in accordance with the requirements of "Interim Measures on Public Participation in Environmental Impact Assessment". Wudu Phase II Irrigation Scheme has obvious irrigation benefits and social benefits without restriction of environmental factors from the environmental point of view.

National Development and Reform Commission approved Sichuan Wudu Water Diversion Schema as one of alternative projects which could use the World Bank loan in the finical year of 2010-2012 (see Annex 2). Sichuan Wudu Hydro-electric Group Co., Ltd., as the owner of the project, was going to apply US$IOO Million (680 million RMB) from the World Bank to construct 12 main (branch) canals in Mianyang prefecture, three on-farm demonstration projects, institutional capacity building and project management under Sichuan Wudu Phase II Irrigation Scheme. Project Leading Office was established by Mianyang Municipal government (No [2010]37, see Annex 3) to ensure the implementation of WIADP. Project Leading Office (PLO) is the organization that is responsible for implementation of the World Bank-financed WIADP (Annex 4). PLO organized corresponding experts team to supply technical support for this project.

Wudu Phase II Irrigation Scheme with total investment 4471 million RMB has two parts in consistence with the investment components, one is financed by the World Bank, which includes the first section of Xizi canal, II branches (sub-branch) and three on-farm demonstration areas, institutional capacity building and project management, the other is financed by the government, which includes the second to the ninth section of Xizi canal, Jinfeng reservoir, 6 branch (sub-branch) canals, Jinlong branch canal and Yonatan Branch canal outside of Mianyang prefecture. The World Bank financed WIADP uses the World Bank Loan US$I 00 million (680million RMB), 15.21 % of the total investment.

4 Environmental Impacts and Mitigation Measures

4.1 EIA Conclusion 4.1.1 Water Environment 4.1.1.1 Impact assessment on water regime of irrigated areas

The main water systems related to WIADP mainly include Fu River, Zitong River and some tributaries. The impacts on runoff regime of the irrigated areas will be mainly posed by crossing-river components and water diversion and interception components of reservoirs during construction period, and posed by all level tributaries which irrigation return water flows into during operation period.

(I) Construction period Tributary gullies where the siphons are located all have small catchment area, and are almost dry during non-rainy season. It is impossible to cause impact on water regime by water diversion during construction.

Staged construction in dry period will be adopted for Zitong River siphon, the first section of Xizi Main Canal to be financed by the World Bank. Right bank part is constructed in the first stage, and then the left bank part in the second stage. In this case, Zitong River water will not be cut off during construction. Water table upstream the cofferdam will be slightly increased. The impact on Zitong River from the contraction will be little.

As the government financed Maming River inverted siphon, Qinglong inverted siphon, Erdongqiao aqueduct and Laoyingshi aqueduct included in Xizi Main Canal component will cross gullies and rivers, and water width of Maming River is about 30m in dry season and has perennial flow, water diversion will be required during construction. Diversion in drought period will be applied. As water flow in these gullies is very small, for which flood flow with return period of five years is smaller than I.Om3/s, water diversion will be less difficult. Flow of rivers (gullies) where other inverted siphons and aqueducts are located is very small and almost dry in dry season. Water in these gullies will not be intercepted and generally there will be no impact on downstream water regime.

Given extremely small flow of Wangjiagou Gully where Jinfeng Reservoir is located, only construction procedure and safety are considered for water diversion and interception. Short period interception will not have noticeable impact on downstream water regime.

(2) Operational period Impact of irrigation return water on local surface runoff during operation will be very limited and concentrated in dry period of rice growth. The replenishment of return water can alleviate the negative impacts on water regime to some extent for the tributary gullies which are discontinuously dry due to drought.

4.1.1.2 Impact on surface water quality

(1) Construction period Impacts on surface water quality during construction are caused by river disturbance due to inverted siphon and aqueduct construction, wastewater from sand and gravel processing,

25

r lj

wastewater from concrete mixing system, and sewage from mechanical and vehicle repair and maintenance as well as domestic sewage. Investigation and analysis show that these will have insignificant environmental impact after appropriate measures are taken.

I) Impact of siphon and aqueduct construction 14 siphons and 37 aqueducts of proposed WIADP will be financed by the World Bank and 7 siphons and 29 aqueducts by the Government. Most of the creek gullies to be crossed by siphons and aqueducts are seasonal tributary gullies with relatively small flowrate. Only flowrate for Zitong River to be crossed by Zitong Siphon is bigger (annual average flowrate 27.2m3/s).

Diversion will be carried out for the Zitong siphon and Maminghe siphon during construction. When constructing cofferdams, water body may be disturbed resulting in SS increase at river sections with construction activities. Comparing with similar projects in the Province, increase of SS beyond 100m downstream of a cofferdam will not exceed 50mgIL. The minimum impact on water quality will be caused general. Moreover, a small amount of foundation pit wastewater may be generated during the excavation for siphon foundation, which should be pumped out of cofferdam for agricultural irrigation or forest irrigation after sedimentation treatment. The impact on surface water environment from the wastewater will be insignificant. Construction of foundation of aqueduct bents will be implemented in dry season, which basically will not pose impacts on surface water environment.

Construction of aqueduct bent foundation will be scheduled in dry season and will have insignificant impact on surface water environment.

2) Impact of Sandstone Aggregate processing wastewater According to the construction plan, the concrete aggregates and strip and block stones needed for small and medium size canals will be outsourced. And no aggregates or stone processing system will be installed. Therefore, pollution on surface water posed by aggregate processing wastewater will not exist.

Chaiba Sandstone Aggregate Processing Plant, located in Chaiba quarry, is within the area of first section of Xizi Main Canal, and the receiving water body is Zitong River. Analysis shows that processing wastewater under normal operation will be treated to meet discharge standard before discharge and will not have adverse impact on water quality of Zitong River.

In accordance with project contraction plan, aggregates needed for the second to the ninth sections of Xizi Main Canal and linfeng Reservoir will be supplied by Xindeba Sandstone Aggregate Processing Plant, for which the receiving body of wastewater discharge is Fu River. During normal operation, the processing wastewater will be reused after treatment and will not have adverse impact on Zitong River water quality.

3) Impact of flushing wastewater discharged from concrete mixing system WIADP is a project in a line shape with dispersed buildings. Considering layout of tunnels, aqueducts, siphons, and reservoirs, concrete mixing systems will be installed in a decentralized manner for components to be financed by the Word Bank and the Government. Compared with similar projects, no flushing wastewater is generated from asphalt concrete mixer. Wastewater is generated when flushing the rotary drum and feed

26

bucket of the concrete mixer. Flushing wastewater will be settled before discharge and will have insignificant impact on water environment near the outfall.

4) Impact of oil containing wastewater discharged from machine maintenance and integrated processing plants According to construction plan, Xizi main canal, Jinfeng Reservoir and medium and small sized canals will cross some large cities and towns including Zitong County seat and Yanting County seat, thus overhaul of construction machinery will totally rely on nearby cities and towns and some small scale machine or vehicle maintenance stations will be established next to the production and residential areas for light repair and regular maintenance.

In general, the amount of wastewater generated from machine and vehicle maintenance in the construction sites is minor. Compared with WIADP Phase I, one machine and vehicle maintenance station generates about 5m3/d wastewater. Most are vehicle cleaning wastewater. The major pollutants are SS and oils with concentrations of 3,000mg/L and 30mg/L respectively. Wastewater generated will not have significant water environment impact near the outfall after sedimentation and oil separation.

5) Impact of domestic sewage For components with a line shape, such as Xizi Main Canal and other small and medium size canals, most workers will rent houses in towns or villages along the project to live. A few small camps will be set up at the inlet and outlet of tunnels which are far away from towns and villages. Thus, domestic sewage generated by construction workers will be extremely dispersed, which can be collected and treated in onsite dry toilet or biogas tank and then used for agricultural irrigation or as fertilizer. Thus, no wastewater will be discharged into water environment. Water quality of the project area will not be impacted. The wastewater from construction workers temporarily living in towns or villages will be collected and treated by facilities in the towns or villages. The impact on surface water is very little.

Number of construction workers in peak period of Jinfeng Reservoir construction will be 850, so construction camps will be built. In accordance with construction plan, the camps will be set downstream dam location and upstream of Wangjiagou Gully. Hydrological information shows that average annual flow at Jinfeng Reservoir dam location is only 0.073m3/s. In this case, direct discharge of domestic sewage generated by construction workers will have significant impact on local water environment as the ratio of runoff and wastewater flow is only 61.8. Therefore, effective measures should be taken for wastewater collection and treatment during construction to meet applicable standard.

(2) Operation period 1) Impact of water conveyed by canals Pollution risk of water conveyed in canal will be very low but management should be strengthened as stipulated in relevant protection regulations on irrigation.

2) Impacts of return water from the irrigated areas Analogical analysis of Wudu Water Diversion Phase I irrigation return water indicates that irrigation return water of WIADP during operation will have insignificant impact on water quality of Fu River and Zitong River. However, return of irrigation water to local water body may pose greater possibility of eutrophication and water quality deterioration in case

27

of small and sluggish flow in some river sections.

3) Impact of Jinfeng Reservoir Analysis of impact of Jinfeng Reservoir on surface water quality during operation is different from other canals. For Jinfeng Reservoir, Dillon model is applied to forecast total phosphorus and nitrogen concentration in reservoir water. The forecast shows that basically it is impossible for breakout of eutrophication in the reservoir.

4.1.1.3 Impact on groundwater

(1) Construction period Impacts on loose accumulation strata pore water during construction are mostly caused by construction of siphon and deep excavation of open canal, while impact on bedrock crevice water is mainly from construction of tunnels. As construction activities of this project have a nature of line shape distribution, project construction will impossibly result in large range groundwater level depression and tunnel construction will have very minimal impact on bedrock crevice water.

(2) Operation period Ground water quality during operation period will be impacted by following factors, irrigation water quality, application of pesticide and fertilizers, and pollutant contents of soils. During operation, residual pollutants introduced by chemical use will have minimal impact on groundwater quality in the irrigated areas. The proposed irrigation scheme has certain topographic elevation difference and preliminary analysis indicates insignificant impact on groundwater because of short irrigation time and rapid discharge. Additionally, there will be no possibility of pollution to groundwater source for potable purpose of rural area.

4.1.1.4 Impact on drinking water source protection zones

(l) Construction period The impacts on drinking water source protection zones during construction mainly posed by direct disturbance of construction activities or wastewater discharge.

I) Impact of WIADP components to be financed by the World Bank According to the project plan, Zitong River siphon at the first section of Xizi Main Canal will pass through the Class
