General Description 1.1 Project Background 1.1.1 Project Source The proposed G31 8Huaining section (1 ) Beneficial to the economic development in the poverty stricken areas; (2 ) Favorable to transportation centralization and decentralization of the main route (Hefei-Anqing Expressway ) ; (3) Fitted for the provincial 0I five-year plan of highway improvement, and priority given to the sections which have started construction but not completed yet in the 9gh five year plan so as to improve efficiency of the whole route and the road network; (4) The existing road sections cannot meet the increasing demand for transportation and need rehabilitation. (5) The average indicators (PQI) of road surface quality are low and surface is poor. G3 18 Huaining section is located in the south central areas of Anhui Province where the major transportation relies only on road for there is no railway to reach these areas. As the economy develops and the transportation increases, the existing road of narrow surface and poor quality cannot match the demands of economic development and transportation. Thus, Anhui Provincial Communications Department is applying for the World Bank loan (remaining savings) to support the rehabilitation of G318 Huaining highway section. The project is of great significance for improving the condition of transportation to the outside in the poverty stricken areas and stimulating local economic development and bettering the people's life. At the request of Anhui Provincial Communications Department of China, in July, 2001, Anhui Provincial Highway Administration Bureau entrusted the job of environmental assessment and preparation of the environmental impact assessment on G318 Huaining section of highway maintenance, to Hefei Design & Research Institute, Ministry of Coal Industry. 1.1.2 Status of Environmental Assessment The assessment unit, after accepting the entrustment, set up an environmental assessment group in July 2001. The group together with Anhui Provincial Highway Administration Bureau and Anhui Provincial Highway Survey and Design Institute carried out field visits and public participation and consultation along G318 Huaining highway section. The group conducted deep field investigation relating environmental status and environmental protective targets along the section. Based on the site visits, data collection and further study of the project feasibility study report, the group worked out the draft "Environmental Impact Report of G318 Huaining Section of Highway Maintenance Component of the World Bank financed Anhui Provincial Highway Project of China". The group got assistance from the environmental experts of the World Bank in the preparation of the report. Now the draft report is ready for the World Bank review.  1.2 Aim of the Environmental Assessment Qualitative or quantitative anticipation analysis and assessment are made on the possible environmental impact to be brought by the project construction. The work has been done on the base of the investigation into the natural and social environment and environmental quality within the assessment range of G3 18 Huaining section, and on the base of the combination with the understanding of the environmental status and relative environmental issues along the section. The report shall point out the potential problems and propose effective and reasonable alleviating measure correspondingly. The alleviating measure shall be put into practice to reduce the environmental impact during the project construction and operation to the lowest degree. The following targets shall be reached as well. ( I ) Possible environmental impact during the construction as well as the impact range and degree shall be fairly and objectively identified. (2 ) Investigation result shall be presented in the report based on the understanding of the public opinions via the investigation along the section. (3) Various measures of prevention, alleviation and reduction to the lowest degree of the negative impact shall be proposed, established on thc result of environmental impact anticipation and applicable compensation methods shall be proposed as well. The aim is to identify negative impact before the construction, raise attention in finalizing the design document and bid contract, and carry out the alleviation methods during the construction period. (4) The environmental assessment shall work as decision making reference, provided to the highway administration departments and local goverrnent institutions along the section in making environmental administration plan and environmental development programs. 1.3 Report Preparation Basis 1.3.1 The World Bank requirements (1) "Environmental Assessment" (OP4.01 ), the World Bank, January 1999 1.3.2 The national environmental protection laws, regulations and technical standard and guideline of assessment (2) "Environmental Protection Law of the People's Republic of China", Dated on December 26, 1989 (3) "Environmental Noise Prevention Law of the People's Republic of China" Dated on Oct. 29, 1996 (4) "Water Pollution Prevention Law of the People's Republic of China" Dated on May, 15, 1996 (5) "Air Pollution Prevention Law of the People's Republic of China" Dated on Aug. 29, 1995 (6) "Solid Waste Prevention Law of the People's Republic of China" Dated on Oct. 30, 2  1995 (7) "Soil and Water Conservation Law of the People's Republic of China" Dated on June. 29,1991 (8) "Highway Law of the People's Republic of China" Dated on July 3, 1997 (9) "Cultural Relics Protection Law of the People's Republic of China" Dated on Nov. 19, 1982 (10) "Environmental Protection Management Rules of Projects under Construction" 253rd order of the State Council, dated on Nov. 18,1998 (11) "Circular on the Management Work of Environmental Impact Assessment of the Projects Financed by International Financial Organizations" the State Environmental Protection Agency, the State Development and Planning Committee, Ministry of Finance and the People 's Bank of China, 1993 (12) "Environmental Protection Management Methods of Communications Project under Construction"(90), Ith order of the Communications Minister (13) "Technical Guideline of Environmental Impact Assessment" HJ/T2.1-2.3-93, HJ/T2.4-1995, HJITI9-1997, the State Environmental Protection Agency (14) "Environmental Impact Assessment Standard of Highway Project Construction (trial) " JTJ 005-96, the State Ministry of Communications 1.3.3 Project Design Document and Relative Data (15) "Studies on the Highway Maintenance Component a Anhui Province Highway Project Financed by the World Bank" dated on Sep. 2001, prepared by Anhui Provincial Highway Survey and Design Institute (16) "Two Phases Preliminary Designs of G318 Huaining Section Improvement Project" dated on March, 2002, prepared by Anhui Provincial Highway Survey and Design Institute (17) Relative data provided by Anhui Provincial Highway Administration Bureau and Huaining County Highway Administration Branch, statistics and data collected in the field. 1.4 Assessment Criteria 1.4.1 Class of Environmental Assessment In line with the criteria set out in the World Bank "Environmental Assessment" (OP4.0 1), the environmental assessment of G318 Huaining highway section subproject should be classified as class A in accordance with Hefei - Anqing Expressway Project which environmental assessment is Class A.
