It also one of "two south-to-north and two east-to-west" trunk roads proposed by the Ministry of Communications to be basically completed by the year of 2000 . By the end of 1997, Beiing--Xinxiang will be built up access-controled expressway while Zhengzhou--Xuchang expressway was completed for openning to the traffic in 1996 ; currently , Xuchang--Luhe expressway is under construction and expected to be put into used around 1998 , also, some preparation for initial stage are being done for Luhe--zhumadian section which is expected to be completed around 2002 . At that time, there would be only left Xinxiang--Zhengzhou section which have to share one road of National 107 , of which is north to Zhumadian on the Beijing--zhuhai national trunk road . In the requirement of MOC's planning, both Beiing--Zhuhai national trunk road and national highway 107 will parallely exist which will undertake different transportation task. Based upon this principle, the status of "sharing one road "at Xinxiang--Zhengzhou section is only temporary solution . Xinxiang--Zhengzhou is a class I highway and was completed in December 1989 also is the first high-grad highway in Henan which play a very active role in exchange communication between both bank of the Yellow River and in improving develpement of economy along the alingment . This section, however, is mixed traffic due to adopting intersection with the other road which produce a serious crossing interruption . In addition, With the city's development , the said section become street degree ,which restrict the benefit of highway and can not meet the demand of fast growth of traffic volume In order to ensure the said section to be smoothly driving prior to completion of Xinxiang--Zhengzhou expressway and the second Yellow River bridge , Henen Provincial Traffic Survey & Planning Design Institute, through comprehensive analysis, proposed to upgrade the highway section into expressway standard ,and the total investment for upgrading works amounts to RMB532.11 million yuan and it is proposed to take use of the savings from the Bank loan under National Highway Project Henan Section and of force account from Henan itself ,in which the savings from the World Bank loan under National Highway Project (Henan section) amount to US$19 million (RMB157.70 million) . As required by relevant environmental management provisions for construction project of the Government and Henan Province 3  as well as EIA provisions for World Bank-financed projects ,a full-scale EIA is required to be completed for this section, for Xinkxiang--Zhengzhou bel-ongs to project class A%. As entrusted by Henan Provincial Highway Administration Bureau-, Henan Provincial Environmental Protection Institute is held responsible for EIA of this section road 1.2 Project Location, Size and Alignment Henan province is located in the center part of China ,and in the middle reaches of the Yellow River (see Map 1-1). The existing class I highway zhenghou--Xinxiang section is situated in the north part of the province, on the both bank of the Yellow River (please see Map 1-2 for the project location of this section). According to the recommended scheme in the Feasibility study Report of the project ,the alignment of the proposed upgrading works specifically is : starting from north at connecting location between Anyang--Xinxiang expressway and national 107 i.e Xinchang interchange ,and it passes through west of Langgongmiao , west of Jinlou, Maotan in Yuanyang county , east of Ciguti , Songlou, east of Xinzhang , then going across the Yellow River ,east of Shaoyuan,east of sangyuan , west of Shilipu , center part of Bai village and Wang village , ending at Longhai railway station(K686+803.5) , with the total length of 69.773km . In accordance with the alternative proposed by the Design Institute , scale and technical standard to be adopted for the upgrading works on XZH is as follows : a : upgrading class I highway in length of 69.773km in which 39.326km is between Xinchang interchange and north bank of Yellow River, 30.447km is between north bank of Yellow River and Longhai railway interchange . b. 39.326km long highway to the north of the Yellow River will be upgraded into the fully-access controlled expressway standard with provision of service road for local vehicle access. The section to south of the Yellow River will upgraded into class I highway with partially *Lccess controlled and with motorized and non-motorized separated and overpass bridge built for pedestrian . c. the section to the north bank of YR will build 1 simple. interchange, 24 separations, reconstruct 9 passageways, 43.5km for local road and 30km for service road and overpass bridge. The section to the south of YR will newly build 9 pedestrian overpass bridges, 2 interchanges at two crossing location and reconstruct 5 intersections. d. to upgrade the section from Xinchang interchang to north bridge bend cap of YR in length of 43.776km to class I highway, rehabilitate 1 service area and toll station at Jinlou and YR of south section 4  ,Apart from above tecommended scheme, the Feasibility Study 7Report.also proposed a alternative scheme which can be seen in the Chapter 2 of this, report. .-Through comparative analysis, the EIA agree the recomSnded scheme raised in the FSR and please see comparative alternatives in Chapter 5 for detail 1.3 EIA Purpose The purpose of EIA for tpgrading of Xinxiang--.Zhengzhou Class I highway includes the following aspects: a. looking into physical eco-environment, agricultural eco-environment and socioeconomic background ,assessing environment quality status of environmental noise, air, ground water at this area and lead content in the farming layer of the soil adjacent area of both side of highway so that environmental status information could be provided for highway upgrading works ; b. analyzing and predicting environmental impacts to be posed to environmental noise, air, lead content in farming layer of soil of adjacent area in both construction and operation periods of this road ; c. proposing all kind of mitigating measures for envirometal protection ; d.proposing environmental management, environmental monitoring program in construction and operation stage; e. carrying out economic evaluation and analysis; f.looking into suggestion or recommendation regarding upgrading works and environmental question put forward by non-government organization and public people ; g. proposing environmental feasibilty for the upgrading works on XZH 1.4 EIA Basis 1.4.1 "Rules for Environmental Protection of Construction Projects" issued by NEPA in Document No.003 (86) 1.4.2 "Rules for Environmental Management of Communications Projects" issued by the Minister of Communications in his Decree No.90(17) 1.4.3 "Regulation for Environmental Protection of Construction Projects, Henan Province" 1.4.4 "Notice on Enhancing EIA Management of International Financing Organization-financed Construction Projects"issued by NEPA, SPC; MOF and People's Bank of China in Document HJ 324(1993); 1.4.5 "Feasibility Study Report of the Upgrading work on National Highway 107 Xinxiang--Zhengzhou section " prepared by Henan Provincial Transport Survey & Planning Design Institute; 5  1.4.6 "Entrust letter on EIA for the upgrading works on XZH' by Henan Provincial-.Highway Administration Bureau 1.5 EIA Class and Highlight -- Based on environment impact features of highway construction- projects and according to the "Specification for EIA of highway Construction Project ," this proposed upgrading work is identified as a Class 1.

On the premise of two conditions , the first one is that Jiaozuo Yellow River Bridge is completed and opened to the traffic by 2001 ,and the second one is that Xinxiang--Zhengzhou expressway and the second Yellow River bridge is completed and opened to the traffic by 2004 .Being completed the upgrading XZH , such section will maintain the status of sharing one road between Jingshen national trunk road and national highway 107 . 2.1.1 Current status of Xinxiang--Zhengzhou class I highway To convient description , three sections will be divided between Xinxiang and Zhengzhou highway ,which is north section to the north bank of the Yellow River (Shanbiao-- Xinzhuang) , Zhengzhou Yellow River bridge, and south section to the Yellow River bridge (south bank to Longhai interchange)respectively . Present status of such three section of highway are described as follows : 2.1.1.1 North Section to the North Bank of the Yellow River (Shanbiao--Xinzhuang) In July 1986 Henan Provincial Planning & Economic Committee (HPPEC) approved the preliminary design of vehicle accommodation road on national highway 107 prepared by the Design Institute with the documentation No.018 (1986), and the length of the road is in 57.595km in total . Class I highway at plain area with access-controled was adopted for the origial design of which design driving speed is 120/h, width of subgrad is 23.Om, two way four-lane and median was adopted . After review of design in 1987,HPPEC approved the project with the documentation No.1668 (1987)that class I highway without access-controled was defined ,i.e common class I highway would be built between north of Xingxiang--PuYang intersection and north bank of the Yellow River (Xinzhuang)with total length of 47.05km , designed driving speed 100km/h , width of subgrad 23.Om,centrer median 1.5m , two- way &four- lane , and with cement concrete being adpoted for the pavement . In addition, the bearing capacity for the bridge is : vehicle- super class 20, trailer--class 120 7  2*8.5m for the bridge width . There are 3 interchanges , 9 passageways, 2 sepa-ration iriterchanges with railway, 62 intersections used for large vehicle lane, 711.42/13 large,medium bridges, 241 culverts ; common class II highway would be built between Shanbiao--Xinpu intersection with length of 10.545km . The section of highway was commenced in March , 1988 and built for opening to the traffic in December 1989 2.1.1.2 Zhengzhou Yellow River Bridge Zhengzhou Yellow River bridge is located above the Yellow River from Huayuanko at north rural area up to Qiaobei village in Yuanyang county of Xinxiang , with 137 spans in 5549.86m , cast-in-place pile foundation ,pile frame-bent abutment, doule post pier, prefabrited concrete simple supported beam , which is bottleneck work for national highway 107 . Being approved by the State , the bridge commenced the construction work in July, 1984 and was openned to the traffic in Oct. 1986. The following is its design , execution magtitute and standard : design discharge : once every three hundred years and disgn discharge Q= 36000m3/s design bearing capacity for vehicle: vehicle--super class 20; trailer-- class 120 bearing capacity for people : 350km/m2 design earthquke intensify : degree 7 width of bridge driving lane : 16.Om width of pedestrain : 28 spans at the south bank is 2*1.5m , and the rest of it is 2*1.Om 2.1.1.3 South section of the Yellow River (from south bank to Longhai interchange ) The section of the alignment is in the length of 20.477m and was built in 1989. The alignment for this section is situated in territory of Zhengzhou city and also near downtown area , with interconnecting between Liulin of north rural area of Zhengzhou and major trunk road on Huoregose This section was designed and constructed as Class I highway ,with design driving speed lOOkm/h,pavement width 25.Om, two-way & four lane, and cement concrete being adopted for the pavement . The designed bridge loading capacity is : vehicle--super class 20, trailer--class 120. There were built 40 intersections (in which 13 of them connecting with highway, 2 of them with the railway , 25 of them with the large vehicle lane ), 756.44m/13 large, medium bridges, and 88 culverts. 2.1.2 Brief Description for the Upgrading works 2.1.2.1 North section of the North Bank of the Yellow Rive.r (starting from terminal point at AXE ending to north bank of the Yellow River ) 8  'Tv The said section ; with total length of 39.326km , will be upgraded - J4nto fully-access controlled expressway with construction of service road . The major work include : newly built 1 simple interchange, 1 toll station (at Jinlou), 24 overpass grad separations, 9 passageways. After the said section being upgraded to fully-access controlled expressway, in order to ensure transportation access for local vehicle , a complete continuously service road , 43.5km in total , need to be paved at the left (eastern) side of alignment , in which involved newly built 7 middle bridges, 9 small bridges, 150 culverts; another service road, 13.30km in length , will be built at the right (western) side of alignment for the purpose of connecting the approach of all grade separations and passageway , and also a discontinuous service road in length of 16.544km will be newly built , both of which are 29.848km for the service road at right side .

The only different section for both of the scheme is that the alternative scheme goes eastward starting from Liulin interchange along the existing Zhengzhou-Kaifeng expressway in length of 15.8km to Yanzhang (interchange to be built)and then goes southward where will built a new expressway in length of 26.2km connecting with the existing Zhengzhou-xunchang expressway .Therefore, comparison between recommended and alternative scheme is comparison both the section for upgrading existing N107 to the south of YRB and the section of newly built expressway . The newly built expressway in length of 26.2km in the alternative scheme consist of two sections with different technical standard . Two-way six-lane expressway standard , 8. Okm in length, will be adopted at the section from Yanzhuang to planned urban trunk road Zhengzhou-Zhongmu , while the section southward will build two-way four-lane expressway in length of 18.2km . The table 2-4 shows the major technical indicators for the newly built expressway The alternative scheme of the newly built expressway have the following work magnitude : the total length is in 26.2km for the newly built expressway with asphalt concrete paved . The subgrade for the whole alignment will adopt borrowed earth and the average height of the subgrade is 4.05m ; newly built 2 large bridges, 2 middle bridges, 3 interchanges, 1 grade 11-,:1  Table 2-4- Main Technical Index for altemative alignment No. description unit index value - remarks 1 ___________________ ________ four lane |six lane - 1 construction length km 18.21 I 2 terrain plain 3 class of highway expressway 4 bearing standard vehicle-super 20, trailor-120 5 design drving speed km/h 120 6 width of carriageway m 2*7.5 12* 11.5 7 subgrade width m 28 35.5 8 median divider width m 3 9 width of left curbe m 0.75 10 hard shoulder width m 3.5 11 soil shoulder width m 0.75 12 drivinevisiblility m 210 13 Max. vertical slope 4 14 Min. radius of curve m 1000 15 designed flood frquency _1/100 11-2  separation overpassing Longhii-railway and NH310 , 4 grade separations crossing with other highways, 38 passageways, 75 culverts, as well as administration and safety facilities . - The cost estimate for the alternative scheme of newly built expressway amounts to RMB 521.6233 million yuan Through comparison analysis to both schemes, it is assumed that recommended scheme in the feasibility Study Report is reasonable (please see the Chapter 5 for comparison of the alternative in detail). Hence, analysis- of environmental impact factors and environmental impact assessment will only focus on the recommended scheme 2.1.3 Origin and Transportation of Construction Material Stone and sand : The norhtwest part of area where Xinxiang --Zhengzhou highway is located belongs to frontier part of Taihang Moutain which is rich in stone resources and quarries has been formed . Stone material required for the upgrading work will be purchased from the region of Luwangfen in Xinxiang, Xinmi in Zhengzhou, Qi county, Weihui, Anyang etc. Such stone material will be hauled by vehicle to the construction site along NTH 107. Sand required for construction work will be supplied by quarry of Suiping Shizhuang , and will be hauled firstly by railway tranSporLation to Xinxiang , Zhengzhou station then to the construction site by vehicles. Soil : The most of construction work on north section of YR are works with higher embankment height over NTH 107 , which will require a large quantity of soil material . As the section of highway is located in flat area without sufficient soil source to be used , soil material will be borrowed from assembly identified location along both side of subgrade Four major material : most of them will be purchased from Xinxiang and Zhengzhou ,and insufficient part of them will be obtained from outside in other city. Cement will be from Xinxiang, Zhengzhou; asphalt product will be used from Shandong and Luoyang oil refinery factory ; Steel material will be supplied from Tianjing, Anyang steel plant; timber will be purchased from Xinxiang and Zhengzhou . Above major four material will be hauled to the construction site by vehicles along NTH 107 2.1.4 Prediction Results of Traffic Volume Beside of the factor social economic development, we still consider the following two factor which will influence the traffic volume : the former is upon openning of Jiaozho YRB in 2001, the vehicles driving toward south will be diverted so that the traffic volume on YRB and south section of YR will be decreaed, while 12  there will be no change on, north section of YR;. cthe latter. is due to openning -f -Xinxiang--Zhengzhou Expressway and the second YRB in 2004, most of pass-by vehicles and part of internal vehicles will divert to the Expressway so that the traffic volume of the proposed project at that time will significantly decrease and later it will be getting grown year by year Prediction results of traffic volume in the Feasibility Study Report are as shown in-the Table 2--4 . Table 2--4 Prediction Results of Traffic Volume of the Upgrading work (middle truck equivalent) unit : No.s of vehicle/day year north section YRB South section of YRB of YRB 2000 14954 27181 21236 2010 10342 20277 12661 2019 16790 34855 23021 2.1.5 Arrangement of Construction Period and Implementation Schedule The proposed project is the World Bank -financed project thus savings of bank loan will be financed. The proposed project expected to commence construction work by December 1998, and completion of work is by the end of September 2000 , with 23 months of construction period The detailed schedule is as follows : year 1997 completion of design and fund raising year 1998 bidding, land acquisition & resettlement, preparation of construction will be completed by early part of this year while work will be commenced by December . year 2000 All contractors put into all their efforts for construction activity , and the project will be opened to public by the end of September. 2.2 Identification of Project Environmental Impact Based on feature of the project, important part of the upgrading work is located on north of YR of which include such construction work i.e pavement upgrading, newly built service road, interchanges, passageways etc.; while on south section of YR, only separating facilities and signal system and over-pass pedestrians as well shall be installed in construction period . Towarding this end, environmental impact of the project construction is mainly on north section of YR. The environmental impact element are as shown as in the Table 2--5 . Table 2--5 Environmental Impact Element for construction period of the Project -13  North sectioq of YR Yellow River South of YR .Bridge * construction noise, * construction * construction. vibration; noise noise .*.onstruction *impact on the *impact on the fume,blown dust due to existing traffic existing traffic material-hauling accessibility accessibility vehicle; during during *flue gas due to construction construction preparation of activity activity asphalt; *wastewater discharge from construction activity * domestic sewsage by construction workers *land area for temporary use *borrow/soil due to construction of subgrade and interchanges _ we can see from above table that environmental impact element is very few on YRB and south of YR of the upgrading project, and also no local resident people would be impacted around YRB in construction period , Due to distribution of many business facilities on south section of YR at where very few resident are living , affected people due to construction noise is very few either. Because of such reason, the EIA Report will focus on analysis of environmental impact on north section of YR in construction period Environmental impact element on north section of YR is basically as same as the element on south section , which is componsed of the following : noise and vibrtio due to vehicles; exhaust of vehicles; land area for permanent use at service road and interchanges; blown dust due to vehicles; road pavement erosion due to rainfall water; traffic accident; social interruption upon completion of upgrading work; Identified results of environmental impact of the upgrading project is summarized in Table 2--6 14  Table 2-6 Identification of Enviromental Impacts Period Impact Enviromental element Air Water Vegetatio Agricultur Irrigation Archaeolo Livelihooc Lands Noise, Vibration 0 0 0 0 0 AS es a Fume, Dust eS 0 0 0 0 eS *S 0 Asphalt Flue es 0 AS AS 0 AS eS 0 constructi Construction water drainage 0 ^5 AS AS AS 0 0 Domestic Sewage AS AS 0 AS ^ 0 AS
