Highways are the major means of transportation within the Region and to the neighboring provinces and countries. Highway transportation plays a very important role in Xinjiang. The Kuitun - Sailimu Lake Highlway (hereinafter the Kuisai Highway) is one part of the Lianyungang - Korgas national trunk highway. It forms a main section of the national trunk highway "Three Longitudes and Three Latitudes". In the Xinjiang 30-year Network Program, it is one part of "Y-type' main passage. It lies in the middle of Eurasian Continental Bridge. Since ancient times, it has been a road for international trade and cultural exchanges between the countries of middle and East Asia. Of 13 opened passes in Xinjiang, the Kuisai Highway reaches 8. Therefore, it is the crucial highway conmectinig eastern and westem areas in Xinjiang. The Country focuses on developing the western regions. Kuisai Highway, as one of the significant projects of infrastructure constrmction, will play a significant role in the development. However, the existing Kuisai highway is of low standard and poor quality, providing poor service to traffic. Its present condition cannot meet the requirements of fast social and economic development in the locale. Following the opening of the Unimqi - Kuitun Highway, it will undoubtedly become a bottleneck to traffic in the section from Urumqi to Korgas Pass. Therefore, the proposed Kuisai Highway will play an important role in improving transportation conditions of the national highway corridor. It will relieve the conflict between poor transportation capacity and fast economic development requirements by removing the bottleneck section from Urumqi to the Korgas Pass, which can guarantee smooth traffic flow on National Road 312, improve the Region's ability to connect with outside areas and accelerate economic development. The State Development and Planning Committee, the Ministry of Conmmunication and the World Bank have in principle approved the proposed Kuisai Highway Project. It will be constructed with World Bank Loan. The Project Executive Office of Xinjiang High Grade Highway Construction Authority has authorized Xinjiang Highway Planning, Survey & Design Institute to undertake the Projcct Feasibility Studies, the Engineering Feasibility Studies and the initial engineering design. It has also authorized Xinjiang Environmental Techniques and Assessment Center to undertake enivironmienital impact assessment. Project Feasibility Study Report has ratified by the State Council on April of 2001 (see SPC Doc. No. 574 (Jijichu 2001) "Notice of Ratifying the Project Feasibility Study Report of Kuitun-Sailimu Take Highway in National Trunk-way of Lianyungang to Korgas"). Environmental Impact Assessment Report of Kuisai Highway Xinjiang, China January 2002 1.2 Assessment Objectives and Categories 1.2.1 Objectives The objectives of construction environmental impact assessment of Kuisai Highway is to survey social and economic status, the natural ecological status, noise environment and the air quality along the alignment of the proposed highway. Such assessment will be in accord with likely features of highway construction and future traffic status. It will forecast and analyse the Project's degree of impact and scope of influence in acoustic and air environment, the natural ecology, agriculture and husbandry and social and economic environment during construction and operation periods. It will make recommendations in prevention measures for technique feasibility and economical reasonable environmental protection and submit a scientific basis for design and administration departments. This is to minimise any unfavourable impact to environment by the Project. Producing a well co-ordinated economy and environment. 1.2.2 Categories Based on the relevant Document No. [1993] 324 "Circular on Strengthening Management of the EIA of the Projects Loaned by International Financial Organizations" by the SDPC, the National Environmental Protection Bureau, the MOF and the Bank of China, the stipulations in the Guideline of Environmental Assessment by the World Bank (OP/BP/GP4.01) and the conmnents on TOR by the National Environmental Protection General Bureau and the World Bank, the Environmental Impact Assessment (EIA) has been completed as "Category A".

Commencing from the western end of the Ururnqi Kuitun Highway, ending at Sailimu Lake a total length of 311.5km. The Kuisai Highway, part of National Road 312 has been a crucial passage for cultural exchange between China and countries to the west since ancient times. For Project location refer to Annex Fig. 1. 2.3 The Alignment and Major Control Points 2.3.1 Start and Finish Points The Project starts from the end point of Urumqi-Kuitun Highway and ends at Sailimu Lake 2.3.2 Alignment and Main Control Points Between start and finish points of the Project, the alignment runs from east to west. The main control points are Wusu City, Gaoquan (Farmn 124), Tuotuo, Jinghe County, Shashanzi (Farm 83), Wutai, Bole Fork and Sitai. 2.3.3 Alternatives There are two alternatives in the Engineering Feasibility Studies Report of the Project. Reference Alternative--- construct a new highway. Proposed Alternative--- upgrade the existing road. The alignment of Reference Alternative runs typically east to west. Westward from Kuitun to K253, it passes under the Kuitun to Dushanzi leased railway. An interchange will be constructed at K254+940 where the highway intersects with Karamay to Dushanzi section of National Road 217. Continuing westward crossing the Kuitun Rive r at 1.5km downstream of the existing Kuitun Bridge. Thereafter, it will cross National Road 312 at K260.3, while to south of the Northern Xinjiang Railway. Further west it passes Gaoquan, Tuotuo and Shaqiudaoban. To avoid a sandy area, the route crosses over the existing road and the railway at K386. The to the south of Shaquanzi to existing railway intersection, it crosses over the railway with an interchange at K407+300. Then back to the southern side of the existing road to Heishantou. Between - 8 - Environmental Impact Assessment Report of Kuisai Highway Xinjiang. China January 2002 Heishantou and the existing road it passes through Huanggonig Village l.Skm south of Jinghe County. Continuing westward to the south of the old road then via Shashanzi and Wutai Town and thereafter crossing over the existing road west of Wutai. Through Bole Fork it runs to the north of the existing road passing Sitai to the end Sailimu Lake connecting the already upgraded road. Alignment and the main control points in Proposed Altematives are basically the same as the ones in Reference Altermative. While Proposed Alternative mostly will use the existing road apart from the three sections in Wusu (Kuitun East Interchange Toudaochangzi Village), Jinghe County (Heishantou - Bajiahu) and Shaqiudaoban - Heishantou with total length of 73.1km. which will be newly constructed, because the two alternatives are quite close.

Chlia Januarv 2002 2.7 Engineering Introduction 2.7.1 Subgrade 2,7.1.1 Design of Subgrade Elevation Only in Jinghc Hcishantou and Sitai road sections, sub-grade needs to be excavated, because they are located in hilly or river beach areas. The other sections of the proposed Highway are located in the Gobi Desert, natural grazing land and faming area. Predominantly this Project is one of subgrade filling. The subgrade fill height mainly depends on topographical conditions, clearances of viaducts, bridges, culverts and underpasses. The average filling height is: expressway 2.7m, Class I road 2.3m and Class II road around 1.2m. According to local geological conditions, the minimum subgrade fill height shall not be less than 1.0m. Subgrade fill materials shall meet the requirements of the design specification. In fanning area, fill shall be taken from designated borrow locations. In the Gobi Desert, materials can be taken from adjacent to the roadside. 2.7.1.2 Subgrade Cross Section a) Subgrade Width of Kuitun to Wusu Expressway Subgrade width 28.0m, lane width 4 x 3.75m, left side strip 0.75m, hard shoulder width 3.5m (including right side strip 0.5m), earth shoulder width 0.75m, median strip 3.00m. b) Wusu to Bole Fork Class I Highway Subgrade width 25.5m, lane width 4 x 3.75m, left side strip 0.50m, hard shoulder width 3.0m, earth shoulder width 0.75m, median strip 2.00m. In this section, Class I road can make full use of the frec land in the existing road corridor. Overall cross section will be applied. In desert without any residents, it is possible to adopt the design of separate Class I cross section. c) Bole Fork to Sailimu Lake Former part is an area of plain, 35km of the section from Sitai to the destination is in hilly area. Considering that the route arranged alongside open valley will not cause too high quantity of hard work and there is no resettlement problem, therefore Class II highway standard for slight hilly area will be adopted for this section, that is, subgrade width 12m and pavement width 9m. 2.7.1.3 Drainage and Protection Works The natural ground slope of the plain area in this Projcct is very slight, especially in the farming area. There is a danger that water will pond adjacent to the subgrade (such as Gaoquan, Bajiahu Farm and Shashanzi). Water does not drain easily through the natural watercourses. Drainage will require detailed design to overcome ponding taking such water through lower elevation ditches. Retaining dykes need to be built at outer side of the ditch to prevent irrigation water from seeping illto the subgrade. The subgrade throughl the long section of the Gobi might be easily flood - 13 Environmental Impact Assessment Report of Kuisai Highway Xinjiang, China January 2002 damaged because of lack of vegetation anid large violent floods. The "Y"-shape water blocks will be set up within this section, and introduce water into bridges and culverts. In river beach sections, side slope of front face embankment shall be consolidated with cast-in-place concrete slab according to the water level of the flood and in combination with bridge diversion works. 2.7.1.4 Earth and Stone Quantities of Subgrade For the estimate of earth and stone quantities, see Table 2.7-1.

China January 2002 2.8 Investment Estimation and Arrangement The first proposal was to make a inew expressway from Kuitun to the Sailimiu Lake. In order to protect fragile ecological environmeit, the best way is to reduce new alignments. Accordingly an alternative was developed where only the 73.1km is new road, the next 180.4km is an upgraded class I existing highway, and the last and most fragile 58km is an upgraded class II existing highway. This is the biggest change of the project from environmental reasons. In order to minimize impacts on residents of Wusu and Jinghe, the bypasses run out of these two places are designed respectively using the existing road and constnicting a new section on the south sides. This is to minimize impacts on residents and to protect cities. In the section of Shaqiudaoban-Heishantou. a new line will be constructed on the south side of the existing road to prevent damages by flood and sand. For Proposed Altermative, the static investment is RMB 2.65 million Yuan; total cost is RMB 2.786 million Yuan. Details see Table 2.8-1.

C hina January 2002 Chapter III The Status and Evaluation of the Environmental Quality 3.1 Introduction of Natural Environment 3.1.1 Topography The proposed Kuisai Highway is located in upper fringes of alluvial and diluvial plains on the northern foot of Tianshan Mountain and the southem edge of Junggar Basin. The section from Kuitun to Jinghe is about 560m-330m above sea level, slanting from south to north and fonr horizontally alluvial and diluvial plains. The section from Jinghe River to Sailimu Lake is 330-2118m above sea level, which belongs to Bortala Valley, in which the section from Jinghe to Wutai slants from south to north and reaches Ebnur Lake, typically low salty swampland. Bortala Valley becomes narrow from Wutai towards west and goes by the basin edge and into mountain gradually, slanting from south to north. The proposed Highway mainly lies at the edge of oasis, passing agriculture fields of 42km (13% of total length) and 269.5km of desert (87% of the total). 3.1.2 Hydrology The proposed Highway is located in the west section of the Northern Tianshan Mountain side stnk belts. The mountain front structure is not obvious from Kuitun to Tuotuo section. and totally disappears from Tuotuo to Jinghe section. The mountain range connects with Quatemary Period stratum so that its lack of adjustment of the mountain front structures. Therefore, the base layer crevice water and river seepage water compensates the plain pyretic water. The underground water is abundant due to small valley area. In the upper fringes of the diluvial fan, the water table lies at a depth of several tens of meters. In the alluvium and diluvium, the water table is below ten meters. The water's degree of salination is carbonate water smaller than 0.5g/l (freshwater). At the edge of alluvial and diluvial plain, that is connection of slanting plain, the spring water overflow area has becn formed. The water table depth is around 2 to 3 meters, it issues in the way of springs and marsh swamp. For example, near Gaoquan. Shaquanzi, Jinghc and Wutai, the water-mineralized degrees are relatively high, wvhich is 1-3g/l sulphate chloride carbonate water (feeble half-salt water). Along the proposed Highway, except some areas, such as Gaoquan, Shaquanzi, Jinghe, where the ground water table is higher, the other areas are all more than 10 meter. From Jinghe County to Kuitun, the water-mineralized degree is less than Ig/l. There is plenty of water. This area is suitable for sand and gravel excavation. It belongs to No. IV loose rock leaking water in the plain. The structure is unique stone and gravel layer. which is very loose and permeable for water. - 19- Environmental Impact Assessment Report of Kuisai Highway Xinjiang, China January 2002 3.1.3 The Status of the River System The rivers in the Project area all belong to the Ebnur Lake water system. The direction of flow for all rivers is from south to north leading to the Ebnur Lake. All rivers originate in the west Tianshan Mountains of Xinjiang. They are in the main Kuitun, Sikeshu, Gurtu, Jinghe and Daheyanzi Rivers. These rivers contain water throughout the year, while most of the water volume is intercepted upstream for agriculture irrigation. The remaining flow tends to be minimal, sometimes disappearing completely. However during flooding water volumes can be extremely high. The flow peak of the large rivers in these areas results from snowmelt and mountain rainstorm in a mixed runoff. Other smaller rivers are the result of rainstormn and intermittent springs. In diluvial fan lands, because of scarcity of plant life, when flooding starts, the converging speed is fast, and current turbulent, resulting in flooding. It is calculated that about IOOkm road section will pass through flow-over area (such as Toto - Shaqiudaoban, Shashanzi - Daheyanzi -Wutai - Sitai section). The flood might damage the highway, so subgrade protection sections will be longer. Main hydrological characteristics of the rivers are shown in Table 3.3-1. 3.1.4 Meteorology The areas through which the proposed highway passes belong to a continental dry climate. Typically, very long and cold winters and very short and extremely hot summers. In spring and autumn, atmospheric temperature rises and falls sharply. The basic climate characteristic in the areas is that the difference in annual and daily temperatures can be great, annual rainfall is little and evaporation is considerable. The annual average temperature is 5.80C-7.30C. Annual average rainfall is 91.4-183.2mm, maximum drifting snow depth reach 1341cm, maximum frost depth reaches 137-172cm. The frost-free period in a year lasts 140-185 days. The frost season begins from November and ends in March of the next year. Maximum wind speed is 20m/s; annual average wind lasts less than 33 days. Annual average maximum evaporation is 1562.4-2046mm, which is greater than rainfall. That is the main reason of the dry climate. Meteorology status in each area along the line sees Table 3.1-1. 3.1.5 Earthquake Intensity The Project area is located in the Junggar Basin sunken belts. Because of the moving of Yanshan Mountain and the Himalayas, the sunken stratum of Mesozoic and Genozoic era in front of the mountain are folded and broken, formning fracture belts parallel to Tianshan Mountain in axial direction. The new structure is moving very strongly. In Northern Tianshan the earthquake intensity zone is very active along route. In 1944, because of the west section of Tianshan Mountain Boluokenu moved a Grade 7.25 (9.28 degree) earthquake occurred in Wusu. For earthquake intensity, according to Division Map of Earthquake Intensity in China (1990) (as Table 5-1), the section from Kuitun-Wusu-Sikeshu lies betveen Class VII and Class VIII, the rest of the route belongs to Class VIl intensity zone. It is suggested that the section from Kuitun-Wusu-Sikeshu precaution be constructed against earthquake of Class VIII intensity and from Sikeshu to Sailimu Lake, of Class VII intensity. - 20 - Environnmental Impact Assessment Repoit of Kuisai Highway Xinjiang.
