Background 1.1 The national road project III of Beiijng-Zhuhai national trunk road (including Junshan Yangtze Bridge) in Hubei province is part of the "Two longitudinal and two lateral" national trunk roads, which shall be built in the year of 2000 as planned by the State Council. The Wuhan Junshan Yangtze River Bridge is an extra-bridge located at the joint section of the Beijing-Zhuhai national trunk road and the Shanghai-Chengdu national trunk road. In December 1992, the Hubei Provincial Communications Administration commissioned the desk study on Hubei section of Beijing-Zhuhai national trunk road. Therefore, in November 1993, the Hubei Provincial Communications Planning and Design Institute (HPCPDI) completed the pre- feasibility study report of Hubei section of Beijing-Zhuhai national trunk road. In December 1993, the Hubei Provincial Planning Commission and the Hubei Provincial Communications Administration submitted the proposal of the project to the State Planning Commission. In September 1995, the additional report related to the two sections of Shanghai-Chengdu route. The HPCPDI conducted the "Pre-feasibility Study Report for Junshan Yangtze Bridge" and the "Feasibility Study Report for the Engineering Work of Junshan Yangtze Bridge". The Hubei Provincial Planning Commission submitted the "Written Ask for Adoption of BOT for Wuhan JunshanYangtze Bridge Project" to the State Planning Commission in October 1995. 1.2 Entrusted by the HPCPDI on behalf of Hubei Provincial Communications Department (HPCD) in March 1994, the Highway Research Institute of the Ministry of Communications (a First Class Certificate holder for environmental impact assessment issued by the National Environmental Protection Agency (hereinafter NEPA)) undertook the environmental assessment study for the national road project III. The "EIA Report for Hubei Province National Highway Project III" passed the preliminary exmination by the Ministry of Comrmunications (MOC) in August 1996, and passed the final examination by NEPA in October 1996, with official written reply. Entrusted by the HPCPDI on behalf of HPCD in May 1994, the Shanghai Ship & Shipping Research Institute undertook the environmental impact assessment studv for the Beijing-Zhuhai national trunk road Junshan Yangtze river bridge engineering project. The "EJA Report for Wuhan Junshan Yanetze Bridge" passed the preliminary exmination by the MOC in August 1996, and passed the final examination by NEPA in March 1997, with official written reply. 13 The EIA report and the EAP (environmental action Plan) for the national road I  project III and the Junshan Yangtze Bridge were submitted to the World Bank deleoation in September 1996. 1.4 Major environment related statutes and standards applicable to the project are as follows. -Environment related statutes: (1) "Environment Protection Law of the People's Republic of China", December 26, 1989; (2) "Atmosphere Pollution Prevention and Control Law Of the People's Republic of China", June 1, 1988; (3) "Water Pollution Prevention and Control Law of the People's Republic of Chi-.a".

Engineering Brief The main road of the project is composed of two parts: Dawu-Shenshan road section of Jing-Zhu route (Beijing-Zhuhai national road) (including Junshan Yangtze bridge); and Wuhan East section and West section of Hu-Rong route (Shanghai- Chengdu national road). The auxiliary enginering work of road includes three connection roads: Dawu link, Huayuan link, and Xiaogan link. The main road is built by motorway standard with total length of 202.8 km; the three connection roads are built by class II standard with total length of 39.7 km. The Dawu-Shenshan section is 143.4 km long, with 11 interchanges, 51 separate grade crossings, 265 underpasses, 5 extra-large bridges, 5 large bridges, with total investment cost about CNY 385.66 million.

Present Situation of the Environment 3.1 Landform and topographical features The area along this route is vast with great landfonn fluctuations. From Dwu to Xiaohe township of Xiaochang is heavy hilly area; from Fu river to Junshan is plain lake area; and the other areas are plain hilly. Soft soil is dispersed over this project area, so that there are about 22.7 km road section of this project have to be treated artificially. Meanwhile, the ground surface is characteristic of long time temporary water storage, with higher water table. The soil quality is poor with great water content; therefore, the soil shall have to be transported from a long distance for subgrade and pavement, which makes the engineering work difficult and the cost up. The geologic conditions of the area in the north of Fu river is quite good, according to the investigation, no areas with poor geologic conditions, such as landslide, rock slide, and soft ground, have been found. Ancient stratum has been found from Dawu to Huayuan, with bedrock along the route shallowly buried and the outcropping rock can be seen everywhere. The stratum from Huayuan to the north of Fu river is dominated by the middle and ancient time Pleistocene series with hard soil texture, along the route. The slope the irrigation canals and ditches is not only steep but also stable with high load capacity. The good geologic conditions provide reliable subgrade for the engineering work. The low-lying land in the road section from the south of Fu river to Junshan is characteristic of short term deposit, soaked with surface water and underground water for a long time, with soft soil texture and low load capacity, except for the highland of Dushan, Hengshan, Zhashan. Junshan, etc. within Caidian area, which has relatively good geologic conditions. The road section in the east of the West Lake area is mainly soil ground with thick and deep soft soil layer. The sections from Quanli to Yangan and from Jinkou to Baoxie belong to corrosion hilly area. Due to the corrosion by surface runoff, the landscape with topographical features of hills zigzagged with ditches has been formed. The average subgrade filling height shall be 3.5 - 4 meters. The section along the route is dominated by soil ground with relatively good geologic conditions with a few rocks; and poor geologic conditions having not been discovered. 5  3.2 Meteorology and hvdrology The impact areas of this project are located in the middle and low latitude, belonging to tropical continental monsoon humid climate featured with clear four seasons, long frost-free period. The annual average temperature is 15 - 17
