They will play an important role in developing the overall benefits of the expressway. Both Zhumadian Prefecture and Xinyang City are less developedagricultural areas. Construction of the expressway and connecting roads will greatly contributeto changing the undevelopedeconomy as soon as possible. 2) Altogether 5 connecting roads will be provided, including 3 in Zhumadian Prefecture and 2 in Xinyang City. These will be upgraded on the basis of existing roads except for south Zhumadian and south Xinyang connecting roads, which will be newly constructed. The total length is 50.62 kin, and the total cost estimate is 281.92 million RMB. 3) The main environment protection targets for EIA purposes are the villages and schools in the range of 200 m on both sides. According to investigation results, there is no school or any other environrnentalsensitive sites in this range. PROJECT DESCRIPTION 4) The 5 connecting roads are as follows: Chenzhuang interchange connectingroad (referred to south Zhumadian connecting road), a new road with a total length of 7.35 kmn; Queshan interchange connecting road (referred to as Queshan connecting road), a 5.87 km road to be upgraded; Minggang interchange connectingroad (referred to as Minggangconnecting road), a 6.1 km road to be upgraded; Fengjiatang interchange connecting road (referred to as north Xinyang connecting road), a 15 km road to be upgraded; and Guopeng interchange connecting road (referred to as south Xinyang connecting road), a new road with a length of 16.3 km. 5) All of the 5 connecting roads are located in the south part of Henan Province, on both banks of the Huai River. They are separatelyaligned as follows: South Zhumadian connecting road: The road will start south of Lianjianghe highway bridge on 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 Chenzhuanginterchange on Zhumadian- Xinyangexpressway. Queshan connecting road: Starting north of Longshan Cement Factory on national road No. 107, heads east to underpass Beijing-Guangzhourailway, goes by north of Guanshan, south of the agricultural machinery repair shop, north of Dapizhuang Village, before it arrives at Queshan interchange on Zhumadian-Xinyangexpressway. This is a part of the existing Queshan-Runan road. Minggang connecting road: The startpointis in the vicinity of WangzhuangVillage 3.5 km east of Minggang-Zhengyangnational road No. 107. It goes east somewhat by north, passing by south of Xiaoliugang, north of Xiaoliuzhuangand Wudian, and links with Zhumadian-Xinyang expressway in the vicinity of Zhouzhuangwhere an interchange is provided. After leaving the expressway, it turns to the northeast and ends at Tianzhuang in Shuanghe Township, Queshan County.This is a part of the existing Minggang-Zhengyangroad. North Xinyang connecting 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, turns north and goes west of Fengtumen, Shierlimiao, Shilihe and Lumiao, and finally ends at Fengjiatang interchange in Yanghe Township. This is also a part of the existing Xinyang-Zhengyangroad. South Xinyang connecting road: Starting at Chuwangcheng safety island in Xinyang City area, this road heads northeastward across the north ring road at Lijiawan, and then goes further northeastward through passes through Waojialaowanand Xiaohuangwan,turns to the east in the range of 1-2 km north of Xinyang-Shihesegment of national road No. 312, and passes through Yangjiawn, Shenjiawan and Zhulin before it links with Zhumadian-Xinyang expressway northwestof Tianwan. 6) South Zhumadian and South Xinyang connecting roads will be constructed according to technical standards for Grade I roads in plain and microhilly areas, while the other 3 are upgraded Grade 2 in plain and microhillyareas on the basis of existing Grade III roads. 7) All kinds of raw and building materialsrequired for these roads will be purchased from local sources and trucked to the site. Soil materialsfor the 2 new roads, as being large in quantity,will come from central borrow area operation,while the limited quantity for the 3 upgrading roads sources from side ditches. ENVIRONE ESCRIPTiN 8) These connecting roads are all located in the south part of Henan Province, on both banks of the Huai River. The project area is in the Huai River alluvial plain, where the flat land does not wave to a great extent. The project area is in the north subtropical-temperatetransition zone with a continental monsoon semi-wet climate. There is a temperate climate, with 4 distinct seasons, including hot sunmmer and cold winter. The rainy season exactly coincides with the hot season. 2 1. Geological conditions along the connecting roads are stable, without any adverse geological sections. The basin intensity is below 6 degrees except in the 50 km range around Xinyang, where it is at 6 degrees. 9) All of the connecting roads are distributed rural areas. The ecosystem is predominated by agricultural eco-environment. Surface vegetation is artificial in most cases, and predominantly crops and field forest belts. Vulnerableecological zones are not found along the alignment. Fauna and flora are common species. Large animals are mainly foul and livestock. Wildlife are mainly rats and insects. Plants are predominantlycrops. No rare and endangered species at the national protection level is ever found alongthe alignrment. 10) Along the 3 connecting roads distributedin Zhumadian Prefecture, soil loss is mainTyin the form of water erosion, which, however, is not serious. With an erosion modulus below 2,000 I tlkm2.a, these are slightly erosive areas. The 2 connecting roads in Xinyang are distributed in moderate erosive areas, with an erosion modulus over 2,500 t/km2.a, and even 3,376 t/km2.ato the maximum. Soil erosion managementover the past consecutive years has put the worsening soil erosion under effective control. I11)Both Zhumadian and Xinyang are agriculture-basedareas with a weak industrial ground. The level of economic development is below the provincial average. They are both less developed parts of Henan Province, so the overall living standard and quality of life are on the lower side in the whole province. 12) Major environrnental impacts in the constructionstage will include eco-environmental and ambient noise impacts, while those in the operationstage are ambient noise and air impacts. 13) Through investigation, there are 10 villages and 1 primary school in the range of 200 m away from the connecting roads. The primary school, Ershilihe primary school at k8+900 of north Xinyang connecting road, has a total number of 15 classes, about 1,000 students and teaches. There is no environmentalsensitive site otherthan these. 14) According to field monitoring along the alignment, the acoustic environment along the 2 new roads is relatively good, so is that along the 3 roads to be upgraded. Equivalent ambient noise levels in both day and night times do not exceed the applicable standard except that they do exceed the standard along Queshan connectingroad in night time. The project area is relatively quiet. 15) Field monitoring results indicate that arnbient air quality along the connecting roads in Xinyang meets Class 2 standard of the "Standard for Ambient Air Quality" (GB3095-1996), but the situation along the 3 connecting roads in Zhumadian is not so desirable, though the standard is met in 80% cases. TSP is the major air pollutionfactor in the entirety of the project area. 3 POTENTIAL ENVIRONMENTAL IMPACTS 16) Environmental impacts in the construction stage will be mainly in the following aspects: green plant reduction due to land use for construction purposes, blocked drainage from Zhumadian city proper during construction of south Zhumadian connecting road, and possible additional soil erosion during constructionof the 2 connecting roads in Xinyang, especially south Xinyang connectingroad. There will be neither loss of fauna and flora nor significant change of basic ecological conditions during the constructionstage. Upon the completion of construction activities, the green plant loss due to construction will be offset to some extent as afforestation is carried out, and soil erosion will be subsequdentlyput under effective control. 17) Generally, the range of construction noise impacts will not be 50 m beyond construction sites, although it may be 100 m beyond in night time. With constructionactivities suspended in night time, however, the normal production and rest of the local
