1. INTRODUCTION
1.1 Geneml Description
1. The proposed Xiaoshangyuan- Lantian Highway project (XLH) is an integral component of National Highway No. 312 from Shanghaito Yining. It is also a key section of the Shaanxi province highway network. The highway links Shangzhoucity in Shangluo district to Luolicun in Lantian county (see Fgure 1.la).
2. The objective of the proposed XLH project is to provide a connecting link between the existing Shangzhou-Xiaoshangyuanand Lantian-Xi'an Class II roads, increase transport capacity and promote the economic development of Shangluo district. It is anticipated that the project will strengthen economic ties in the region, by facilitating transport of commodities and the transfer of technology.
3. The physicalcomponents of the project include constructionof a 48.28km long Class II motor vehicle highway, including: six tunnels with a total length of 2470m, the longest of which will be 1,670m; 7 large bridges, 22 mediumbridges and 12 small bridges. The project will entail acquiring 1575 mu (105 ha) of land, 880.3 mu (58.7 ha) of which is agricultural, and demolishing8923.3 me of buildingarea.
1.2 Significant Envis onmental impacts
4. Significant environmental impacts during project construction include temporary agricultural land disruption, soil erosion, and impacts on water and air qua;kty. Major anticipated operational impactsincludeairquality degradation, increase n background noise-levels and lead pollution to crops along the proposed alignment.
1.3 Considerationof Project Alternatives
5. The proposed alignment was selected from four alternatives (See Figure 1.3a) on the basis of minimizingboth soejo-econoinicand environmentalimpacts.

' 2. ENVIRONMENTAL IMPACTS AND PROPOSED MITIGATION MEASURES 2.1 SignifcanntE nvironmental Impacts 6. The major environmental impacts of theproposed XLH project are summarized below. 2.1.1 Location Issues i. Relocation, Cultivated Land Acquisition and Social Disniption 7. The total cultivated area impacted by construction of the highway is 58.7 ha. A total of 16 villages will be affected as a result of agricultural land acquisition or resident displacement. Agricultural land acquisition will affect 361 families (a total of 1771 people) who will need to be compensated with land of similar or superior quality. In addition, 18.9ha of agricultural land will be temporarily disrupted where the topsoil will be removed and subsurface soil excavated to provide construction materials. The topsoil will then be replaced and the land restored to its original use. :G. The road construction activities and operation may also impact access between communities and farmland for pedestrians and vehicles. The locations of sensitive sites and residential areas are shown in Map I appended to this report. *9. Dctails of resettlement and land acquisition compensation issues are provided in a separate Resettlement Action Plan (RAP). ii. Cultural and Historic Sites 10. Two historic sites were identified along the alignment during a survey of cultural and historic locations undertaken during the EIA (see Map 1). Neither of these are listed as protected and they will not be directly impacted by the proposed highway. 2.1.2 Construction Phase 11. Potential construction phase impacts include disruption of areas adjacent to construction locations and excavation sites, soil erosion, potential air quality degraation, and noise and vibration disturbance resulting from construction activities, blasting and transportation of construo.tionmaterials. Impacts on water course and water quality may also arise where bridges are constructed across water courses or sand is excavated from flood courses. Map I shows the locations of water course along the alignment. 12. Soil erosion is of major concem during the construction phase. It is anticipated that uncontrolled soil erosion due to construction activities will be approximately 8 to 12 4 times current erosion levels. Prevention measureswill be adopted cspeciallyat excavation and fill sites to minimizeerosion potential. 13. An eslimated, 135,107 ni of earth and 2,270,117 m3 of stone will be excavatcd with estimated utilization ratiosof 88 and 41.4 percent respectively. Therefore significant volumes of surplus will be generated and stockpiledal various locations along the alignimentwhich may contribute to soil erosion and disruptionof vegetation cover. Improper disposal of debris and carth miayalso lead to obstruction of water courses during nood periods. Adequatc and secure disposal of the anticipated excavation debris is a signilicant concern and shall be managedas discussed below. 2.1.3 Operation Phase -' 14. Operation of the road may lead to air quality degradation and an increase in background noise levels. Backgroundair quality monitoringindicates that current pollution j IIlevels are withinClass II NationalAnmbient Air QualityStandards. No significantimpacts on atmospheric quality are anticipatedduring the operationphase. In the proposed tunnels, air quality is expected to meet Design Standards for Tunnels (JTJ026-90) wilicil stipulates a maximumii CO level of 150ppmunder normialoperating conditions. 15. Since the road is to restrict access to all but mnotorvehicles, the risk from mixed vehicle type accidents will be eliminated. Althoughindustrial development along the alignmentis minimal, the road's importance as a link between Xi'an and Shangzhou municipalityand as a component of the nationalhighway network will increase the risk of traffic accidents resulting in chemical and other hazardous materialsspills. Emergency response measures and surveillancefacilities along the propose highway and in the 1.67 km tunnel are planned to respond to spill incidents, and mitigate impacts on the ecological environment and human health. 16. An additional potential impact is a slight increase in lead content of green leaf vegetables grown along the alignmentwhich is anticipated to exceed National Food Hygiene Criteria after 20 years of highway operation. 2.2 Proposed Mitigation Concepts and Measures 17. Environmentalprotection strategies for the project area are as follows: a. project design includes elements which optimize opportunities for environmental improvemiientand avoids or minimizes adverse environmental impacts. Where avoidance or minimizationis not possible, economically and technically feasible mitigation measures have been formulated and shall be implementedwithin a reasonable time frame; 5 b. environmental protection measures include mitigation of impacts during design, construction anicloperation phases of lhe project. 18. E:nvironmentalimprovement measures include upgrading existing dirt roads along routes used for transport of materials. This reduces fugitive dust and irnprbvcsrural traffic movement. In addition, diversion of throughtrafrli' form "'e center of villages will have a net positivc impact on air quality and noise levels within scititenients. It will also 1 serve to reducc congestion and the risk of accidents which may involve loss of human life or release of hazardous materials. 2.2.1 Design Phase I i. EnvirominentalConsideration 19. The project was formulated and authorized in accordance with the "Three Synchronization" rule, whichi requires that all developimienltand construction projects incorporate environmentalprotection measures in planning, design, construction and j operation phases. 20. Environmentalfactors have been taken into considerationin order to ininimize visual impacts and the need tor physical alteration of the landscape, as well as impacts to natural resources, sensitive ecosystems, cultural resources, agricultural lands and populated areas. ii. Route Selection - 21. The alignment of the proposed Xiaoshangyuan-Lantianhighway was selected from among four alternativeson the basis of minimizingland acquisition, adverse air quality and noise impacts on sensitive sites and residential areas, as well as avoiding cultural relics and unfavorable geological conditions. n22. In comparison with the other three alternatives, the proposed alignment is environmentallypreferable on the following points: 1. Ninety percent of die alignment is located in Qinling mountainarea, making useof favorable natural terrain along Qipanheand Lanqiaoheriver valley. As | a result, agricultural land acquisition, land excavation and land fill, and impacts on natural scenery are minimized. X 2. The route is shorter thanthe other alternatives and makes use of the existing Class 11 road in some sections. Road construction is therefore shorter and disruption to the natural and socio-economicenvironment is minimized. 6 3. Six ttunelswith a totallengtlh of 2470m,including one, I ,670mlong, are desiginedat the scctions with unfavorable topography whicil reduce destruction of natiuralvegetation, topography and potential soil erosioninduced by large amount of' land CUland lanclfill. 4. Tlicrcare fewresidential areas along the alignmentand thealignment detours aroundpopulated areas. This reducesresident displacement, relocation and noisedisturbalce. iii. SocialDisrupLion 23. Provisionshave been madein the projectdesign for residenitialareas aflfccted by lhe proposeddevelopment. Thcse includereducing right-of-way land requirementsand minimizing severanceor local access roads in selectinigtransportation routes. 24. Seven large bridges, 22 medium bridges and 12 small bridges have been incorporatedin theproject design as well as 16 crossingsto facilitateaccess to farmland, avoid commnuniityseparation and meel requirements of vehicle access. iv. Soil Erosion 25. Topographicaland geologicalcharacteristics of the alignment require that both engineering solutionisand stabilization tlhroughafforcstation be adopted to reduce surface erosion and prevent land subsidence. 26. A totalof 3130m of slope protection, 20643mnof retaining walls (hIeightrange from 3-8m), and 119 culverts have been incorporatedin the engineeringdesign so as to avoid soil erosion, slope failure and facilitate natural drainage. Drainage courses and silt traps will also be installed on slopes and emnbankmentswhere appropriate to prevent slope collapse and sedimentation impacts on water courses or fields. Temporary and permanent drainage systems were designed to minimize soil erosion and alteration of hydrological regimes, including impactson irrigation and artificial ponds. Drainage channels will be properly lined where necessaryand directed to discharge ponds so as to avoid direct discharge to farmland. 27. An extensive landscaping program has been integrated into the engineering design, takinginto account topographicaland geological characteristicsalong the alignment, to prevent potential soil erosion due to construction activities and during operation. This program will be initiated from the very beginning of road construction. Where appropriate, grading and revegetation of cut slopes, ernbankrnents, median dividers, shoulders, closed borrow sites and waste soil mounds will be undertaken. Following the completion of activities at each site, grading will be undertakenand trees and grasses will be planted. 7 U~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ v. Dust/Air Pollution 28. Quarries, borrow areas and transportationroutes, as well as waste disposal sites have been identiried, taking into account the transportationdistance from the material borrow sites to constructionsites (see Map 1). Dust and atmosphericpollution impacts from these areas were evaluatedwith particular emphasisto protectionof environmentallysensitive locationssuch as residentialareas. 29. Ventilationmeasures have been incorporatedin the design of the longesttunnel to ensure adequate ventilationin order to avoid accumulationof pollutants such as CO ane NO,L. Eighteen c-flractor fans shall be installed at regular intervals within the tunnel to facilitate ventilation. Details are provided in the project engineeringreport. vi. Water Pollition 30. Permanent and temporary drainage systems are incorporated in the project design to minimize surface water pollution and disturbance to irrigation channels and drainage systems. 31. Sanitary waste water facilities (septic systems) have been incorporatedin the service station design proposed at Muhuguan. This station includes re-fuelingfacilities. In order to prevent direct discharge to surface water bodies, contaminated runoff shall be collected into settling tanks prior to discharge. 32. Undergroundstorage tanks for gasoline and other hazardousmaterials shall be installed in a crypt with adequate monitoring facilities to detect leakage and prevent groundwater contamination. vi. Waste Construction Material Disposal 33. Twelve debris disposal sites have been included in the project design to stockpile surplus construction materials. These will be covered with soil and restored for cultivation. One of the largest debris sites. located in Putao Valley. will be restored for agricultural use. 34. Debris from tunnel excavation and quarry activities will be used to upgrade existing access road surfaces especially those affected by transportationof construction materials or shall be used for other local constructionprojects. 8 vii. Noise 35. Other than considerationof alternativealignments, noise screening measures such as forest belts have been integratedin the design and bid documents. The proposed I alignmentselected has minimalnoise impactson sensitive sites and residentialareas. 1 viii. Flooding 36.

The EnvironmentalMonitoring Plan of the project has been formulated in consultation with the Shaanxi Provincial Highway Survey and Design Institute and the Shaanxi ProvincialInstitute of EnvironmentalScience. 74. As detailed in the EIA report, the overall project impactswill be minimized due to sound planningand implementationstrategies on the part of the project proponents. An overall monitoringprogram has been formulatedin order to (i) ensure early detectionof conditionsthat necessitateparticular mitigationmeasures, and (ii) provideinformation on the progress and consequencesof mitigationmeasures. 75. The purposeof monitoringactivities during highway construction and operation is to determinethe influenceon air, noiseand vibration,and water qualityso that appropriate mitigation measures can be undertaken to alleviate any identified impacL Monitoring parameters,network distribution and frequencyhave been determinedaccording to the nature and locationsof potentiallysignificant impacts as well as results of the baseline monitoring program. 32 MonitoringPlan: Schedule,Parameters and Locations 76. Baselineenvironmental monitoring along the alignmentwas performedby the Shaanxi Provincial EnvironmentalMonitoring Center (SPEMC) between 1993 and 1994, which includedair qualitymonitoring, background noise levels, surface water quality, and soil and crop lead content monitoring. 77. In addition, a survey of habitat and wildlife along the alignment was undertaken. No ecologicallysensitive locations were identified. 14 78. A systematicmonitoring plan is presented in Table3.1. The detailed locations of monitoring sites are shown in Map L. 3.2.1 ConstructionPhase i. Air Quality Monitoring 79- TSP will be monitored four times per year for 3 consecutivedays, once in the morning and once in the afternoon, by the environmentalmonitoring group of the Centrl Supervision Laboratory. Monitoring will be undertaken around the construction sites, quarry areas, material borrow sites and major roads used for transportation of construction materials. Monitoring results will be assessed in relation to Class II National Air Quality Standards (GB 3095-82). 80. Fugitive dust monitoring wil1be undertakenby environmentalsupervisors at each contract lot every 5-10 days. Dustpans will be placed in at least 6 sampling locations at construction sites, quarries and material borrow sites and major access roads. More frequent monitoringwill be undertakenduring the beginning stages of construction. ii. Noise and Vibration Monitoring 81. Noise and vibration monitoring will be undertaken by environmental supervisors on a weekly basis, two-three times per day (once in the morning, afternoon and at night) at construction sites and major access roads for transportation of construction materials. Ad hoc noise monitoring will also be undertaken as appropriate.
