General Description 1.1 Project Background 1. 1. I Project Source The proposed S328 Nanzhao-Funan-Yangqiao highway section is one of the highway maintenance component of Anhui Province applying for the World Bank loan. This component is selected from more than 400 highway sections totaling 8000km long, based on the comparison conducted by Anhui Provincial Communications Department of China. The criteria of selection for the highway maintenance component are: (1) Beneficial to the economic development in the poverty stricken areas; ( 2 ) Favorable to transportation centralization and decentralization of the main route (Hefei-Anqing Highway ) ; (3) Fitted for the provincial 1IOh five-year plan of highway improvement, and priority given to the sections which have started construction and completed tasks of subgrade widening or land acquisition under the 9' five year plan so as to improve efficiency of the whole route and the highway network; (4) The existing road sections cannot meet the increasing demand for transportation and need rehabilitation. (5) The average indicators (PQI) of road pavement quality are low and pavement is poor. S328 Nanzhao-Funan-Yangqiao section is located on the north of Huai River of Anhui Province where the major transportation relies only on road for there is no railway to reach these areas. Therefore the improvement of road pavement and the increase of the communication capacity directly relate with the local economic development and people's living quality. As the economy develops and the transportation increases, the existing road with low grade, narrow pavement and poor quality cannot mect the demands of economic development and transportation. Thus, Anhui Provincial Communications Department is applying for the World Bank loan (remaining volume) to support the rehabilitation of S328 Nanzhao-Funan- Yangqiao highway section for the sake of improving local condition of transportation to the outside. stimulating local economic development and bettering the people's life. According to the requirement of Anhui Provincial Communications Department of China, in July 2001, Anhui Provincial Highway Administration Bureau entrusted the job to Hefei Design & Research Institute, Ministry of Coal Industry, of environmental assessment and preparation of the environmental impact assessment on S328 Nanzhao-Funan- Yangqiao section of highway maintenance. 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 S328 Nanzhao--Funan- Yangqiao highway section. The group conducted deep field investigation relatingts environmental status and environmental protective targets along the section. Based on the site visits, data collection and further study of the I  project feasibility study report and under the direction and assistance of the environmental experts of the World Bank, the group worked out the draft "Environmental Impact Report of S328 Nanzhao-Funan-Yangqiao section of Highway Maintenance Component of the World Bank- financed Anhui Provincial Highway Project of China". Now the report is submitted to the World Bank for review. 1.2 Aim of the Environmental Assessment The report shall make qualitative or quantitative anticipation analysis and assessment on the possible environmental impacts caused by the project construction, on the base of the investigation into the natural and social environment and environment quality within the assessment scope of S328 Nanzhao-Funan-Yangqiao section, and combined 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 measures 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. (1) Provide basis for the decision making relating the project, fairly and objectively identify and describe possible environmental impacts during the construction as well as the impacted scope and degree, so as to assure the rationality and appropriation of the construction and operation of the project. (2) Investigation result shall be presented in the report based on the understanding towards the public opinions via the investigation along the section. (3) Various measures of prevention; alleviation and reduction to the lowest degree of the negative impacts shall be proposed, established on the 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 Bureaus and local government 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 2  (3) "Environment 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" Dwlel on Aug. 29, 1995 (6) "Solid Waste Prevention Law of the People's Republic of China" Dated on Oct. 30, 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 for Projects under Construction" 253' order of the State Council, Dated on Nov. 18, 1998 (11) "Environmental Protection Management Methods of Communications Project under Construction"(90), 1 7horder of the Communications Minister (12) "Circular on the Management Work of Environmental Impact Assessment of the Projects Financed by Intemational Financial Organizations" the Stale Environment Protection Agency, the State Development & Planning Committee, Ministry of Finance and the People 's Bank of China, 1993 (13) "Environmental Impact Assessment Standard of Highway Project Construction (trial) "JTJ 005-96, Ministry of Communications (14) "Technical Guideline of Environmental Impact Assessment" HJ/IT2. 1-2.3-93, HJ/I'2.4-1995, HJ'T19-1997, ihe State Environmental Prolection Agency 1.3.3 Project Design Document and Relative Data (15) "Studies on the Highway Maintenance Component * 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 S328 Nanzhao--Funan-Yangqiao 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 municipal highway administration bureau, statistics and data collected on site. 1.4 Assessment Criteria 1.4.1 Class of Environmental Assessment In line with the criteria set in the World Bank "Environmental Assessment" (OP4.01 ), the environmental assessment of S328 Nanzhao-Funan-Yangqiao highway section should be classified as class A in accordance with Hefei-Anqing 3  highway Project which environmental assessment is Class A.
