The construction of it will play a very important role in realizing the hub function of Gan-Yue Expressway, improving local comprehensive transport network. It provides an important basic condition of opening to the outside world for Suichuan countv. According to the requirements and suggestions of the World Bank experts, we have made the Envirorunental Assessment Report for this linking road separately. The Research Institute of Highway (RIOH) under the MOC completed the EIA of Suichuan Linking Road (Version 1) for Gan-Yue Expresswav Taihe-Ganzhou Section in June.2000. In accordance with the suggestions in the aide-memoire at the second preparatory mission by the World Bank environmental experts for Jiangxi NO.2 highway. the RIOH made modification and compiled this EIA report. In December 2000, the EIA team again modified this EIA report in accordance with the aide-memoire at the pre-evaluation mission of Gan-Yue Expressway (Taihe-Ganzhou Section) of the World Bank environmental experts. 1.2 Assessment Basis (1) People's Republic of China Law on Environmental Protection (26 Dec.. 1989): (2) People's Republic of China Law on Water Pollution Control (I 5 Mav. 1996); (3) People's Republic of China Law on Atmospheric Pollution control (29 Dec., 1995) (4) People's Republic of China Law on Environmental Noise Pollution Control (29 Oct.. 1996); (5) People's Republic of China Law on Water and Soil Conservation (29 June.1991) I  (6) People's Republic of China Law on Land Management (29 Aug.,1998) (7) Act of Environmental Protection and Management for Construction Projects [The State Council, C. 253] (18 Nov., 1998); (8) Announcement on Further Management of Environmental Impacts Assessment of Construction Project Loaned From Intemational Financial Institution [(1993) No.324 Document on Environmental Supervision, issued by China National Environmental Protection Bureau etc.]; (9) World Bank Operation Handbook OP/BP/GP 4.01 Environmental Assessment, March 1999: (10) Technical Guiding Provisions for Environmental Impacts Assessment (HJ/T2.1-2.3-93, HT/T2.4-1995.

The protective targets include: farmland. woodland, pond. high filling/cutting section (KO+000-K2+750.K4+200-K4+750). earth borrowing area (K14+400-K14+680). Meijiang river and canals. The impact factors on acoustic and ambient air include construction noise. secondary dust. Traffic noise and tail gas. The protective targets are presented in Table 1-6. As the construction of this road is the up-grade on the existing old road, no great impact would occur from the point view of ecological environment.. The main impact on the surrounding residents, schools and living comes from construction noise and traffic noise as well as tail gas in operation phase. Therefore environmental protection targets in this project are the sensitive locations to noise and ambient air along the road.  Table 1-6 Sensitive Locations to Noise and Air along the Road Distance from Households No. Name Location Central Line of /Number of Environmental Features Road People Hongshan . 330 Enclosing wall around the school.

TSP. 1.5.2 Assessment Method In this report. the environment noise and atmospheric environment are assessed by 6  status monitoring and surveying statistic analysis, and predicted by analogic analysis and module computation. The analogic analysis is used for the prediction assessment at the construction stage, while the module computation is employed for the prediction assessment in the operation stage. According to the predicted results, the range up to the standard is given and used as a basis for the developmental activity conducted by the planning / construction department. Meanwhile, the locations sensitive to noise / waste gas environment are predicted and assessed. The ecological environment, water, and soil-and-water loss are assessed by surveying combined with analogic analysis, while the social environmnent, living quality and public participation are assessed by surveying analvsis. 1.6 Assessment Category and Key Points This works is the expanding construction and rebuilding project. There are environmental sensitive locations as schools and residential areas along the road within the range of assessment. The building of bridge has a certain influence on water environment. but smaller influence on ecological environment and soil-and-water erosion. According to Technical Guiding Provisions for Environmental Impacts Assessment, it is required that the assessment of special subject is analyzed. in which ecological environment (including soil-and-water loss) is assessed to be Category 111, water environment and atmospheric environment be Category III respectively, and acoustic environment be Category 11. According to features and pollution of this project, the assessment of acoustic environmental impacts is a key point in the assessment of this project. 7  Chapter 2 Project Overview 2.1 Alignment and Major Controlling Points The proposed road starts from Suichuan interchange of the main road, via Daquan, Hongshan, Huanggang, Zhongping, Dongtang, Zhangtang, Meijiang, Shaoxi, Hongtaxia (Niutou Computer station), Yangcun, Anxia, Jihe, Shangmaocheng, Zhuzitouxia, Xizhuang and ends at Jinggangshan highway, with a total length of 20.596km. Basically, the proposed road runs along the old road and is built by Class II highway standard. The design speed is 80 km/h with 12.Om for roadbed width. 2.2 Scale of Construction, Technical Standards & Quantities of Main Works According to the prediction of traffic volume. by reference to the regulations in JTJOO 1-97 Technical Standard for Highway Engineering and JTJO 11-96 Highway Alignment Design Specifications (The Ministry of Communications). the whole road is built by Class II highway standard with design speed of 80 km/h . and its main technical indicators and quantities of main works are shown in Table 2-1.
