Background of the Project 1. The study work of Xiangtan-Leiyang Expressway belonging to Hunan highway corridor project (formerly termed MXiangtan-Leiyang Section of Beijing-Zhuhai National Highway, Xiangtan-Yizhang Expressway') started in September, 1992. The prefeasibility study report of the project was finished in November, 1993, and the feasibility study report was completed in May, 1995. The preliminary design was finished in February, 1995. As agreed upon by Hunan Provincial Communications Department and experts from the World Bank in October, 1995, this project contains Xiangtan-Leiyang highway (the main road), nine linking-roads and the subproject-Loudi-Lianyuan Class II Auto-only highway. 2. The Highway Science Research Institute of the MOC was entrusted with the environmental assessment for the project by Hunan Communications Department in September, 1993. The research institute holds Class A certificate on environmental assessment awarded by China National Environmental Protection Agency (NAPA). The project's Environmental Assessment Synopsis was examined and approved by the National Environmental Agency in April, 1995. The environmental impacts assessment was examined and approved by both the Environmental OFFice of the Ministry of Communications and the National Environmental Agency in November, 1995. 3. The experts from the World Bank has checked the following reports: Environmental Impacts Assessment (EIA) in April, 1995, Environmental Assessment Plan (EAP) in July, 1995, Environmental Assessment Summary (EAS) in November, 1995, all the three concerning Xiangtan- Leiyang Highway Project and its eight linking-roads. Besides, the world Bank experts checked the EIA and EAP of the subproject, i.e. Loudi- Lianyuan Highway, the EIA of the linking road between Tian Taishan in Zhuzhou and Yi Shuhe (Tianyi road) in Xiangtan respectively in Duly, November, November, 1995. Based on suggestions given by the experts after checking the aforementioned reports, final revisions have been made by the assessing unit and Hunan Provincial Communications Department. 4. Major regulations and standards on environment adopted in this project. Regulations: (1) China Environmentai Protection Reaulation (2) China Atmospheric Pollution Prevention Regulation (3) China Water Pollution Prevention Reqiulation (4) China Cultural Relics Protection Regulation (5) China. Environmental Noise Prevention Regulation (6) China Land Management Law (7) (86) NAPA No. 003 Document, i.e. Environmental Protection Manaaement Measures for Constructive Proiects I  (8) (90) No. 17 by the MOC, i.e. Environmental Protection Management Measures for Communication Constructive Projects Environmental Standards: (9) GB 3095-82 AtmosDheric Environment Quality Standards: (10) GB 3096-93 Urban District Environmental Noise Standards; (11) GB 3838-88 Surface Water Environmental Quality Standards. Specific Limitations concerning each environmental standard are shown in Appendix VI. 5. Scope and Period of Assessment (12) In this project, the assessment scope of atmosphere, noise and cultural relics is on both sides 200m away from the proposed highway's central line. That of ecological environment and ordinary waters is also 200m, but that of wildlife and air pollutant is to be extended to 500m on both sides away form the proposed highway's central line. The scope for studying social, economic and life quality value is the concemed areas along the whole line including regions or cities as well as districts under their jurisdiction. (13) Assessment standards of the project are as follows: GB 3095-82 Grade II Standard for atmospheric environment; GB 3096-93 Urban District Noise Standards as reference for noise environment; Class IV standard for schools and hospitals; Class II Standard for residential areas; Class II standard defined in GB 3838-88 Surface Water Environmental Qualitv Standard forwaterquality. (14) According to the characteristics and construction period of the project, the assessment period limitation is hereby defined as the year 2020, the predicted year number for specific phase being as follows: construction phase (1996-1999); early operation phase, 2000; medium operation phase, 2010 and late operation phase, 2020. B. Brief Introduction to the Project 6. Xiangtan-Leiyang expressway is 1 68.847krn in total length and will be built under the standards of highways in plains or lightly hilly area with designed drive speed of 1201akh, 27.5m of subgrade. It is a total access controlled expressway with 9 interchanges, 85 Grade separation, 8 extremely big and big bridges. Besides, there will set up complete facilities including 3 service areas, 3 parking lots, 3 administration stations and 9 tolling stations. Land to be used is 20500.91 mu (equal to 1366.73 hectares, including temporary landuse). It is estimated the total investment is 4.302 billion yuan. There are 9 linking roads with a total length of 39km, in which the distance of 8 roads amounts to 23km in length. 7. The linking road between Tian Taishan in Zhuzhou and Yi Shuhe in Xiangtan is the longest included in Xiangtan-Leiyang highway project. It has a total length of 16.056km, being Class I road and containing 4 lanes. 2  The designed drive speed is 1COkm/h and the subgrade is 24.5m. Altogether there will set up 2 interchanges. 4 level intersection, 3 big and medium bridges. Land to be used is 1124.57mu (equal to 74.97 hectares). It is estimated that the total investment is 123.68 million yuan, and the earth and stone work is 1.1 51208 million m3. 8. Loudi-Lianyuan Class II Auto-only highway is 59.6km in total length, with 4 lanes and designed drive speed being 80km/h. The subgrade is 1Sm. Besides there will set up 4 big bridges, 4 interchanges, 50 grade separations and 5 tolling stations. Land to be used is 2835 mu (equal to 189 hectares), with 4.65749 million m3 of earth and stone work. The estimated investment amounts to 426.23 million yuan. C. Description of the Primary Environment 9. Topographical Features (1) The proposed Xiangtan-Leiyang rcad is located in the mid-south of Hunan Province, whose altitude decreases from the middle to both north and south: in north lies the Xiangtan-Hengshan red soil basin; in the middle extends Shiwan-Than lightly hilly or hilly terrain; in the south is the sout,hern Hengyang basin. Landforms along the road are mainly erosive- accumulative plain and slightly hilly terrain. In some areas is lightly hilly or hilly terrain erosive-denudation of erosive denudation. The seismic degree is less than IV deqree. (2) The Tiantaishan-yishuhe linking road lies between Zhuzhou city and Xianr'tan city, both located in Middle Hunan Province. Topography of the arca is plain or lightly hilly land. of quite great undulation. Hilltops are perfectiy round and bedrock appear exposed in most paris. (3) Loudi-Lianyuan highway is situated in Middle Hunan Province, topographically being low hilly land with some sections atong the road having quite great undulation. General feature is that the altitude decreases form both south and north to the middle, and that the river valley is relatively wide. The areas where the project lies are of heavy soil erosion. 10. Climate and Hydrology The project areas have a temperate climate with four distinguished seasons, adequate heat, concentration of rainfiall, varying spring temDerature, drought-attacked summer and autumn, short-term coldness ano long-term summer. The annual average temperature is 17.2-17.9
