It is one section of the second East-West Highway of the "Five North- South and Seven East-West Highway " configurations under planning of China. The second East- West Artery Highway stars from Dandong via Beijing and destined at Lhasa, one of the major passageways connecting Northeast China, North China, Inner Mongolia, Ningxia, Gansu, Qinghai and Tibet. The construction of the projected highway will play a substantially important role in booming the economy and extending the opening of Inner Mongolia and western provinces or regions of China. The Inner Mongolia Communications Department (IMCD) asked the Inner Mongolia Transport &Traffic Design Institute (IMTTD) to undertake compilation of "the Project Feasibility Study Report" (PESR). The report was completed in November 1998. In order to carry out the EIA simultaneously as the study report, the IMCD entrusted Xi'an Highway University to work out the EIA statement on December 4, 1998. Immediately after taking the task, a task force consisting of technicians and designers was organized and a field specific survey was conducted in detail. Based on the survey and information obtained, the TOR for EIA was worked out in January 1999. The TOR was reviewed and examined by the Assessment Center of the National Environmental Protection Agency (NEPA). Taking account into the reply to the TOR and the opinions of the experts, we conducted a further field survey and investigation, and the EIA statement (Chinese version) was compiled December 1999. June 9, 2000, the environmental impact statement was pre-examined by the Environmental Protection Section under the MOC, and it was improved and added according to the opinions of the experts and representatives. August, 2001, the Environmental Impact Statement was revised and added according to the new version of the Engineering Feasibility Study Report complied by IMTTD in Feb. 2001. October, 2001, the EIS was further modified according to Mission Aide Memoire (September 22-28, 2001). We express our genuine thanks to the following institutions and companies for their generous help in our assessment: IMCD, Inner Mongolia Environmental Protection Bureau (IMEPB), IMTTDI, Inner Mongolia Meteorology Division (IMMD), Wulanchabu League Communications Section (WLCS) and Wulanchabu League Environmental Monitoring Station (WLEMS).

and Hebei) to Jining of the national artery from Dandong to Lhasa (called Laoyemiao to Jining Highway or the Proposed highway hereinafter) is a section of Dandong-Beijing-Lhasa Highway in Inner Mongolia, one of the planned national artery highway configuration. It is a truck line connecting north China and the northwest of China. It is also one of the most important passageways to the outside. Its construction will definitely promote the formation of economic zones in both the central cities and areas along the proposed project, promoting the economical boom and investment environment in these areas. It will play a substantially important role in exploitation of resources and transport of agricultural and husbandry products in the central and western parts in Inner Mongolia. In addition, the construction of the alignment will speed up the passage capacity of the national artery highways, thus encouraging the highway construction and improving the infrastructure facilities of highway in Inner Mongolia. The destination of the proposed alignment is Jining, the capital of Ulanchabu League, 360 km away from Beijing and 120 km from Hohhot, and 240 km from Zhungeer coalfield, one of the national key energy bases. It is 270 km away from Baotou, the largest industrial city in Inner Mongolia. The City of Hohhot is one of the important "economic growth zones" of Northeastern Asia Economic Ring and the urban systems of the Economic Belt round Bo Sea. It is also one of the focused points of opening of the north borders, being one of the leading cities in booming the economy in minority regions in the development strategy of the country. Hohhot together with Baotou and Yikezhao League has formed the "Gold Triangle" of abundant resources in Inner Mongolia. Therefore, the construction of the highway will be of great significance in improving contact with outside and extent of opening, and thereby encouraging the economic growth in the central part in Inner Mongolia. It will also play an important role in the commodity circulation and getting rid of poverty in the towns, counties or banners. To sum up, the construction of Laoyemiao to Jining Highway is not only necessary, but also substantially urgent. 1.2 Purposes of Assessment 1. Survey, monitoring and analysis of the pertinent natural environment, social surroundings and the existing situation of environmental quality; 2. Prediction (analysis) and assessment of the impacts of the projected highway on the environment along the proposed highway during both the construction phase and operation phase; 3. Proof of the positive and negative impacts on the environment on both sides resulting from the highway construction and putting forward necessary environmental protection measures to minimize the adverse impacts to get coordination of highway construction and environmental protection; 4. Proof of the feasibility of alignment and construction of the highway from the viewpoint of environmental protection; 5. Provision of information for environmental management in the projected highway and in the design of environmental protection works. 1.3 Policy and Lawsfor Assessment I Law of Environmental Protection ,People's Republic of China (PRC) December, 1989; 2.

The recommended whole route is a completely new alignment. It lies in the mid-western part of Inner Mongolia being one section connecting Hohhot and Jining as major cities in Inner Mongolia. It passes through Xinghe County and the City of Jinning. For its geographical location, see Figure 2-1. 2.1.2 Major Controlling Points The starting point of the recommended option is at Laoyemiao on the border between Inner Mongolia and Hebei Province (Station K273+720). It heads from east for west to the destination (at station K365+000, Sanhaonandi of Jining via Chengguan Town of Xinghe County (south of the town), Toudaunaobao, Jiabazibei, Niuming Village, Bayintala and Shaquan. The main line crosses 208 National Highway here. 2.1.3 Route Alignment (Recommended Option) Laoyemiao to Jining Highway goes from east to west in principle. The section from Laoyemiao to Toudaonaobao goes in the south of the existing highway. However, the section from Toudaonaobao to Niuming Village the proposed alignment goes in the north of the existing highway. For more detail, refer to Appendix Figure. 2.2 Construction Scale and Major Technical Standards The total length of the recommended route is 91.28 km with a total cost of 1,779,373,900 yuan RMB. It is suggested that the whole line be newly built by adopting expressway technical standards. The width of subgrade is 26 m. The construction period is three years (2002-2004). The major technical indexes are shown in Table 2-1.

On either sides of the dividers, there is a curb belt with a width of 0.75 m. There are two driving lanes with each being 3.75 m wide. There are a 3.25 m hard shoulder and a 0.75 m earth shoulder. The standard subgrade sectional drawing is presented on Figures 2-2(a) and 2-2(b). (2) Subgrade slopes Section of filling: When the elevation of filling is less than 6 m, the cut slope is IH:1.5V. While the elevation is more than 6 m, the cut slope is 1: 1.5 at the upper part and 1:1.75 at the lower part with the division at 6 m. Sections of cutting: In case of earth cutting, the cut slope is 1:1.0; in case of stone cutting with light wind erosion, the cut is 1:0.3; in case of stone cutting with severe wind erosion, the slope is 0.75; when the elevation of cutting is higher than 20m, the slope is 1:0.5 or 1: 1.0 depending on the extent of wind erosion. (3) Subgrade protection For general sections, the cut slopes are protected with mansonry meshes and grasses; for the dry sections, the slope are protected with mansonry meshes and clay covers; for the cutting sections, the slopes are protected with slurry schists depending on the conditions. 7 u~ 0 Emergenc Tel e 2750/2 2450/2 Marker Sign Emergency Telephone . - (150) .. 75 32 5 2x375 .75 150!100 S0. 20175 2 50 7s . 5 Slope Protection Squares i 32 x 50 2 ~ ~ ~ ~ ~ ~ ~ ~ -2 50 100 240 200 00 240_100,,50 Separation I I Fence Horizontal Line ' Highway Boundary __ Right-of-way r _ _ _ _ _ _ _ _ _ _ - - ~ ~ ~1 Figure 2-2(a) Sketch Map of Standard Subgrade Cross Sectioni (Fill Subgradc) so.ggf ~ ~~~~~ 3E ,V2 R a X Z 50~~~~O0 ~ ~ u to - Separation Fence v r c c00 60 Lin 1.t . k )0 t& I~~~~~~~~~~~~~~~~~~~~~~~-lorizontal Lino __ 0 | Xj ~~~~~~~~2 7 5 0L 2 4 50Oi/2 /"O / eocn75, 325 2x375 75 150 100 50 2x375 250 1 75 @ L 7 Boundary Marker , F : 2 t.,Marker Sign Slurry Schist Slope Pr6tection - Piping I Staon Gu Right-of:way K -2 1 0 0v 1 50
