Preface 1.1 Project origin In order to develop water saving irrigation undertakings. alleviate the contradiction of water shortage and increase the yield of grains, vegetable and fruit. the Ministry of Water Resources decide to apply for 77 million US$ loan from the World Bank to be used in Hebei. Beijing, Shenvang and Qingdao four provinces and municipalities. Xinchenzi, Yuhong, Sujiatun. Dongling, Xinmin. Liaozhong, Kangping and Faku eight districts and counties (cities) totally 38.9 thousand ha cultivated land were selected as the project areas of Shenvang Municipality. These project areas are located in the alluvial plain of Liao River and Hun River where the water resources are relatively short and water saving irrigation has become an urgent issue for development. The water facilities are in good conditions and the staff has certain experiences in water saving irrigation construction in the project areas. The implementation of the project will further improve the conditions for agricultural production. increase the agricultural yield and farmers income and facilitate the sustainable utilization of water resources and the sustainable development of agriculture. However, the adoption of water saving irrigation will change the distribution of water resources and the related agricultural measures for yield increase will also exert impact on local water resources utilization and the water, soil and ecological environments, therefore, it's very necessary to assess the impact of the water saving irrigation project on the environment. Entrusted by the Comprehensive Agricultural Development Office and led off by the Institute of Water Resources and Hydropower Research, the Water Resources Bureau of Shenyang Municipality assist to undertake the compilation of the environmental impact assessment report. 1.2 Assessment basis, criteria and classification 1.2.1 Assessment basis "Environment protection regulations of construction project" No. 253 issued by the State Council of the People's Republic of China "State technical guidelines for environmental impact assessment"(HJ/T2.1-2.3-93) "Environrmental impact assessment regulation of water resources and hydropower project"(SDJ-302-88) Project proposal book of Shenyang Water Conservation Project "(1998.10.13) "Water environment finction region of Liaoning Province" "PIP report of Shenvang Water Conservation Project" -'Guidelines for environmental impact assessment of the World Bank" 1.2.2 Assessment criteria 'Standard for irrigation water quality"(GB5084-92) The fourth classification water qualitv standard in "Quality standard for groundwater"(GBl/TI4848-93)  The fifth classification water quality standard in "environinent quality standard for surface water"(GB3838-88) 1.2.3 Assessment classification The assessment classification of the project was determined as B according to the "guidelines for environmental impact assessment of the World Bank" and the "state technical regulations for environmental impact assessment" and in association with the project situations. 1.3 Environment protection objectives The main environment protection objectives are: ' Maintaining the balance of water resources supply and demand and can't result in the descent of groundwater level for the implementation of the project; Adopting effective measures and applying fertilizer and pesticide appropriately, ensure not to increase the pollution of groundwater and other environment. 1.4 Assessment procedures Shows in chart 1.1  E n *| u 0| 7U 4u Analysis on the influence to social economic development Analysis on the influence of the construction process to the environment | AE An'alysis on the influence of pesticide and fertilizer to water environment 1 E 2 |1 0 > .

Project 2.1 Generals 2.1.1 Project characteristics The project is rehabilitation and extension project, i.e. undertake canal lining in paddy field, sprinkler irrigation in dry field and micro-sprinkler irrigation and pipe irrigation in vegetable field. The project will be constructed from 2001 and completed in 2005. 2.1.2 Project scope Eight districts and counties (cities) totaled 95 townships involved in the project and the planed irrigated area is 580 thousand mu. Of which, 27 thousand mu in Dongling district, 57.4 thousand mu in Yuhong district, 50 thousand mu in Sujiatun, 58 thousand mu in Xinchengzi, 100 thousand mu in Xinmin city, 103 thousand mu in Liaozhong county, 93 thousand mu in Faku county and 95 thousand mu in Kangping county. Their geographical locations are detailed in the sketch map of Shenyang Municipality water saving project areas. The construction component of the project include irrigation system and management system of water saving irrigation project, agriculture, forestry, agro-machinery, environment protection, SIDD development, construction of MIS svstem and institutional support and development. There are totally 7.73 thousand ha paddy field, 18.83 thousand ha dry field, 9.11 thousand ha vegetable field and 3.23 thousand ha cash crops in the project areas. Their total agricultural output value is 744 million RMB yuan. The relief is flat, the communication is convenient, the water resources are in good conditions, the plots are concentrated, the economic foundations are strong and the masses have capacity for funds collection in the project area and are in conformnity with the selection principles of project area. 2.1.3 Project objectives The overall objectives of the project are establishing and improving the agricultural irrigation system and the high efficient agricultural productive service system and improving the ecological environment and agricultural productive conditions in the project area and achieve the following objectives: * increasing water use efficiency;
