G(ENERAL 1.1 SIGNIFICANCE OF PROJECT Beijing-Zhuhai road is one of the 4 national truck roads (2 longitudinal and 2 horizontal) to be completed by around 2000 as planned by the Government. With Beijing-Xinxiang segment completed as an expressway at the full length, the existing Grade I road from Xinxiang to Zhengzhou remained as it is in the transition period (preparatory work constructing another expressway is underway), Zhengzhou-Xuchang segment completed and opened to traffic, Xuchang-Luohe expressway completed and put into service by the end of 1998, and Luohe- Zhumadian expressway started in late 1998 and expected to be completed by early 2001, Zhumadian-Xinyang expressway with a length of some 133 km is the only segment to be completed in Henan Province before Beijing-Zhuhai national truck road is totally completed. Active financing and accelerated preparation for the proposed expressway will gr-eatly encourage the completion of expressway segments in Henan on schedule, the formation of a fast highway network based on expressways in Henan as early as possible, and the promotion of economic development and social advance in Henan, especially along the alignment. Connecting roads to an expressway are an important part of the expressway per se, and ties to link the expressway with the existing cities and highway networks for the establishment of an | easy and efficient road transportation system. They play an important part in developing the overall benefits of an expressway. Zhumadian Prefecture and Xinyang City are both less developed agricultural areas, the expressway including connection roads will greatly contribute to change the backward economy as early as possible. The proposed expressway has 5 connecting roads, including 3 in Zhumadian Prefecture and 2 in Xinyang City. The connecting road south of Zhumadian and that between Xinyang City to Shiheqiao will be newly built, while the rest 3 will be upgraded. The total length is 50.62 km, requiring a total estimate of 281.92 million RMB. 1.2 PURPOSE OF EIA All of the said connecting roads are located in rural parts, including 2 to be newly built and the other three to be upgraded. In light of this characteristic, this EIA is intended to achieve the following purposes: 1.2.1 Finding out the present situation of eco-environment, acoustic environment and air quality in the project area through monitoring, investigation and assessment; 1.2.2 Forecasting and analyzing the scope and degree of project impacts on ecology, noise and air quality during (construction period) and after (operation period) construction of the connecting roads, analyzing social impacts to be caused by the project; 1.2.3 Arranging environmental impact mitigating/offsetting measures for construction and operation periods in light of the environmental setting and the environrnental impacts  arising out of the connecting roads, developing environmental management and monitoring programs for the construction and operation periods; and 1.2.4 Environmentally justifying the alignment adequacy and feasibility. 1.3 BASIS OF PREPARATION 1.3.1 Law of Environment Protection, PRC 1.3.2 Law of Land Management, PRC 1.3.3 Law of Agriculture, PRC 1.3.4 Law of Soil Conservation, PRC 1.3.5 Law of Highway, PRC 1.3.6 Law of Air Pollution Prevention and Control, PRC 1.3.7 Law of Water Pollution Prevention and Control, PRC 1.3.8 Law of Noise Pollution Prevention and Control, PRC 1.3.9 Law of Cultural Relics and Historical Sites Protection, PRC 1.3.10 The World Bank OP4.01 Environmental Assessment, January 1999 1.3.11 Regulation for Environment Protection of Construction Project, issued by the State Council in letter No. 253 1.3.12 Regulation for Environment Protection and Management of Construction Project, issued by the Minister of Communications in letter No. 17 (90) 1.3.13 Circular Letter on Enhancement of EIA Management of Construction Project Financed by International Financial Institutions, jointly issued by NEPA (National Environment Protection Agency), SPC (State Planning Commission), MOF (Ministry of Finance) and People's Bank of China in letter No. 324 (1993) 1.3.14 Henan Regulation for Environment Protection of Construction Project 1.3.15 EIA Letter of Assignment issued by Henan Highway Administration Authority. 1.3.16 Project Feasibility Study Report (first draft) prepared by Zhumadian Highway Headquarters; 1.3.17 Technical Guidelines for EIA (HJ/T2.1, 2.2, 2.4, 19), and 1.3.18 Specification for EIA of Highway Construction Project (on a trial basis) (JTJO05) 2  1.4 ENVIRONMENTAL STUDY AREA AND APPLICABLE STANDARDS In light of the environmental conditions in the project area and the project features, the study area is tentatively identified as follows: Eco-environment impact assessment: within 300 m on both sides of connecting roads; Ambient noise and air impact assessment: 200 m on both sides of connecting roads; Eco-environmental impact assessment: 300 m on both sides of connecting roads; Physioenvironmental/socioeconomic study and public consultation: cities and counties involved in the connecting roads. According to Zhumadian/Xinyang Environrment Protection Agency, the following standards are proposed to be applied to this EIA: Environmental quality standards: * AAmbient noise: 70 dB(A) in day time and 55 dB(A) in night time for general areas within 200 m on both sides, 55 dB(A) in day time and 45 dB(A) in night time for hospitals and schools within this range; j Ambient air: Class II standard as defined in "Standard for Ambient Air Quality" (GB3095-1996); and Pollution control standards: - "Noise Limits for Boundary of Construction Site" (GB12523-90) j * "Comprehensive Standard for Air Pollutant Discharge" (GB16297-1996), Class 2 as shown in Table 2 * . - "Comprehensive Standard for Sewage Discharge" (GB8978-1996), Class 2 as shown in Table 2 Methodology standards * Measurement of Ambient Noise Levels in Urban Areas (GB/T14623); l * Technical Guidelines for EIA - General (HJ/T2. 1); | .

The expressway is in Zhumadian Prefecture and Xinyang City in the south part of Henan, on both banks of the Huai River. There are 5 connecting roads to the expressway, including 3 in Zhumadian Prefecture and 2 in Xinyang City. Those in Zhumadian Prefecture are on the north bank of the Huai River, they are south Zhumadian connecting road (new), Queshan connecting road (upgrading) and Minggang connecting road (upgrading) from north to south. The other in Xinyang City are on the south bank, they are north Xinyang connecting road (upgrading) and south Xinyang connecting road (upgrading) from north to south. Geographic locations of Henan, the expressway and the connecting roads are as shown in Maps 2-1 and 2-2 attached hereto. 2.3 ALIGNMENT AND MAIN CONTROL POINTS 2.3.1 South Zhumadian Connecting Road According to the location of the south Zhumadian interchange on the expressway, in view of the general planning of Zhumadian City, the aligmnent and main control points of the subject connecting road, as recommended in the feasibility report, are initially as follows: 7  . I I / Map 21 Geographical Locationof HenanProvince0* ;tMap 21- -' Gegrphca Lcaio o Hna Povnc  MAP 2-2 GeograPhical Location of Zhu-Xin Expressway Conneing Road  The connecting road will start south of Lianjianghe highway bridge provided for national road No. 107, passes across the old national road No. 107 (used as street now), goes through the north part of Jinqiao development park, crosses Beijing-Guangzhou railway and Lianjianghe River, passes through the south part of Liulou Village, through Zhuanghu Village and north part of Chenzhuang Village, before it ends at Chenzhuang interchange on Zhumadian- Xinyang expressway (at station No. KI +100), covering a total length of 7.35 km. This will be a new road with straight and smooth lineshape. It will serve as the south ring road reserved for Zhumadian City, about 5 km from the city proper, without any existing municipal facility on both sides of the alignment, so there will be nearly no conflict with the municipal development program. 2.3.2 Queshan Connecting Road This connecting road will be upgraded by using a part of the existing Queshan-Runan Yoad. The upgraded road segment is aligned to start north of Longshan Cement Factory on national I road No. 107, head east to underpass Beijing-Guangzhou railway, go by north of Guanshan, south of the agricultural machinery repair shop, north of Dapizhuang Village, cover a distance of 5.87 km before arriving at Queshan interchange on Zhumadian-Xinyang expressway (station No. K1 8+950); The existing Queshan-Runan highway is at Grade 3. The connecting road will be the west part of this road. The existing road to be upgraded has a subgrade width of 11 m and surface width of 9 m, with open space reserved on both sides for the purpose of upgrading. 2.3.3 Minggang Connecting Road This connecting road is to be provided by upgrading a part of the existing road between Minggang and Zhengyan. The existing road includes a 3.5 km segment east of national road No. 107 in Minggang Township governed by Xinyang City. This segment, as being already upgraded as Grade II concrete road by Minggang Township, is not included in the proposed connecting road. As a result, the alignment of this connecting road is arranged as follows: The startpoint is in the vicinity of Wangzhuang Village 3.5 km east of national road No. 107. It goes east somewhat by north, passing by south of Xiaoliugang, north of Xiaoliuzhuang and Wudian, and links with Zhumadian-Xinyang expressway in the vicinity of Zhouzhuang where an interchange is provided (Minggang interchange at station No. K53+150 of the expressway). After leaving the expressway, it turns to the northeast and ends at Tianzhuang (endpoint chainage No. 69+600) in Shuanghe Township, Queshan County. The total length is 6.1km. The existing Minggang-Zhengyang road is at Grade 3. The segment to be upgraded has a subgrade width of 9 m and surface width of 7 m. The range within 200 m on both sides is almost all farmland, without any compact community. This connecting road will make Zhengyang easily accessible to the expressway. 8  2.3.4 North Xinyang Connecting Road This connecting road is to be built by upgrading a part of the existing Xinyang-Zhengyang road. Starting from national road No. 107, it goes eastward for 4 kin, arrives at the safety island at Xinyang Tobacco Bureau, heads northeast to Wangjiawan, grade crosses the north ring road at Qilidun, turn north and goes west of Fengtumen, Shierlimiao, Shilihe and Lumiao, at finally ends at Fengjiatang interchange (k83+000) in Yanghe Township. The total length is 19 km, with 4 km city road excluded from the project, so the actual mileage of upgrading is 15 km. 2.3.5 South Xinyang Connecting Road According to the location of the south Xinyang interchange and the municipal planning of Xinyang City, the startpoint is arranged at Chuwanghceng safety island in Xinyang City proper. This connecting road is aligned to go northeast, cross the north ring road at Lijiawan, turn north and go west of Gaojialaowan and Xiaohuangwan, deflect east and go through Yangjiawan, Shenjiawan and Zhulin before it connects with Guopeng interchange (chainage No. K95+150) northwest of Tianwan. The total length of this upgraded road is 16.3 km. 2.4 TRAFFIC VOLUME FORECAST As forecast in the feasibility study report, the traffic volume by year will be as shown in Table 2-1 below.

Main technical indices of these connecting roads are included in Tables 2-2 through 2-4. 2.6 CONSTRUCTION CYCLE AND SCHEDULE It is scheduled to complete preparatory work by the end of 1999, project design and tendering by 2000, commencement of works before or after the second half of 2000, bridge/culvert, subgrade and some surface works by 2001, all surface works and supporting facilities by 2002. Construction will be completed by early 2003, covering a total of 3 years. 2.7 MAIN QUANTITY OF WORKS The main quantities of works involved in the 5 connecting roads are included in Table 2-6 through Table 2-11. 2.8 COST ESTIMATE AND FINANCING As roughly estimated in the feasibility report, the total project cost will be as follows: 126.13 million RMB, including 53.77 million RMB for south Zhumadian connecting road, 19.11 million RMB for Queshan connecting road, 13.98 million RMB for Minggang connecting road, 68.93 million RMB for north Xinyang connecting road, and 126.13 million RMB for south Xinyang connecting road. The project financial requirements are proposed to be met by 3 financial sources: loan proceeds of the World Bank, subsidies of Henan Department of Communications, and self-financing of the local government. The World Bank loan, taking up 40% of the total cost estimate, will amount to 13.5864 million USD at an exchange rate of I USD=8.3 RMB. 2.9 SOURCE AND TRANSPORTATION OF BUILDING MATERIALS Steel, cement and timber required for the connecting roads will be purchased from the market in Zhumadian and Xinyang, while asphalt is purchased from within or out of the province. All of these major materials will be trucked to the construction site via national road No. 107. Stone materials for the project will be from Queshan and Shihe quarries, and sand will be from Suiping and Huaihe sand borrow areas. Both will be trucked to the construction site. The hauling distance will be less than 50 m. The subgrade will be generally 1-1.5 m high. The 2 new roads will require a larger quantity of soil, which is proposed to be met by central borrow area operation. As for the rest 3 roads to be upgraded, the quantity of soil works will not be large, and soil materials will be generally taken from roadside.
