As an individual document, this Plan involves all actions and activities taken during the construction and operation phases of the proposed project so as to protect the environment in the proposed project area. It will serve as the principle and framework for implementation of control measures, management and monitoring of environment during construction and operation phases. This plan is composed of four parts: 1) General description; 2) Potential impact brought about by the proposed project; 3) Environmental management plan; and 4) Environmental monitoring plan. Objective of Environmental Management Plan Environmental management is one component of project management and a key link for carrying out the environmental protection effectively during the implementation of project. The objective or purpose of environmental management is to guarantee the implementation of all the environmental or mitigation measures so as to control or alleviate the adverse effects on the environment, and to promote the balanced and coordinated development of local socio-economy and eco-environment. The proposed Mianyang Environmental Improvement Project (Infrastructure and Access Improvement in Pioneer Park and Economic Development Zone financed by The World Bank Loan) is designed in accordance with management regulation of infrastructure construction and is reviewed and assessed strictly according to relevant standard and specifications. All these undertakings are aimed at minimizing potential negative impact on social economy and environment through proactive mitigation measures of environmental protection. 1.0 INTRODUCTION 1.1 Source of the project In term of economic development, there is still a big gap between East China and Mianyang, which locates in West China. The city still lags behind in infrastructure construction. Along with the implementation of the strategy of West China Development, it is of important significance to develop the Pioneering Park (being referred to as West District hereinafter) and the Economic Development Zone (being referred to as South District hereinafter) to improve infrastructure and living standard Page 4 of the local people, to strengthen the service function of the city, so as to promote overall social and economic development. According to current development, Mianyang Municipal Government has put forward the aim of building the West District and South District by making use of the World Bank loan to achieve the objectives. This is very crucial in giving impetus to the economic development of the city. Thus Development & Reform Commission of Sichuan Province issued a reply to the Proposal of Mianyang Environmental Improvement Project Financed by the World Bank Loan by a formal document No. CFGW[2004]No. 617. According to the proposal, following infrastructure and access improvement work will be completed during the construction phase of the proposed project. In West District (Pioneer Park), 22 roads will be paved in width of 9~50m and total length of 21.23 km. Rain/storm water drains and trunk sewers will be laid together with the road construction, totally 91.79 km in length. In South District (Economic Development Zone), 17 roads will be paved with a total length of 24.53 km in width of 14~80m. Rain/storm water drains and trunk sewers will be laid together with the road construction, totally 74.56 km in length. In addition, one interchange, one flyover including lighting and traffic management system will be built in West District. In South District, one flyover, four bridges, greening space (2X2ha), Fuwongyan River flood control embankment in length of 4600m will be constructed. Total investment of this project is 1.3546512 billion yuan, of which 414 million yuan will be the loan of World Bank. 1.2 Contents of project and major components of construction 1.2.1 Contents of Project (1) Location of the Project The proposed project is of infrastructure development in two industrial parks, West District (Pioneer Park) and South District (Economic Development Zone). a. West District It is located in the upstream area of Fujiang River and Anchang River, adjacent to the Southwest Science & Technology University in the north, to the Mianyang Hi-Tech Development Zone in the south, and to China Academy of Engineering Physics (CAEP) and the existing urban center in the east. b. South District It is located in the southern area of Mianyang, about 2.5 km to the existing urban center; Huarun Beer Brewery and Nanshan Road are near the northern boundary; Nanjiao Industrial Park is in the south, Nanjiao Airport is in the west, and Mianyan Highway in the east. Its water surface is in the range from Dongfanghong Bridge to 200 m downstream of the Sanjiang Dam. The total planned area is 22.7 km 2 , among which 12.64 k m 2 of land and 5.06 k m 2 of water surface. (2) Contents of construction Page 5 a. West District (Pioneer Park) The project components of West District (Pioneer Park) include: (1) road construction in Paifanggou Zone and Dabaoliang Zone (including drainage, lighting and traffic management system), and (2) stormwater and sewage drainage system of Yingbin Avenue. Paifanggou Zone and Dabaoliang Zone are located in the north and southwest areas of the Park, respectively. It is planned to construct 21.23 km of roads, one interchange, a flyover, 91.79 km of sewers and stormwater drains, and greening. The project components are given in Table 1 below.
