(ZCSETI) for the World Bank financed Qinghai Province Xining Urban Transport Project. The EMP was prepared based on the main conclusions and recommendation from the Environmental Impact Assessment (EIA) report. The main contents of the EMP include: the institutional arrangement for the implementation of EMP, the major environmental issues in the project implementation and operation, the environmental mitigations measures in different phases, the monitoring plan and reporting system, the training plan and cost budget. In the project appraisal process, the EMP will be reviewed and approved by the World Bank financed Qinghai Xining Urban Transport Project Office, and will be implemented during the project implementation phase. The environmental impact assessment is an important task during the project preparation phase. Its purpose is to assess the potential impact of the proposed project on the social environment and the natural environment, and then prepare mitigation measures accordingly. During the project preparation phase, the purpose of EIA report preparation is to ensure that all environmental issues raised are addressed and incorporated into the following phases. While the purpose of the EMP is to propose measures or methods to eliminate, reduce or mitigate the adverse environmental impacts, so that the adverse impacts can be reduced to an acceptable level. The project design and the environmental impact assessment should be an interactive process that can integrate different factors including the engineering, cost, and environmental impacts in the alternative comparison and selection. The EIA has been conducted as an assignment of the project preparation and appraisal. This EMP was prepared as part of the EIA report. The preparation of this EMP was based on the findings in the EIA process, especially the adverse impacts identified for the project construction phase and operation phase, and appropriate mitigation measures to comply with the national and local environmental standards, and with the applicable World Bank safeguard policies. The EIA documents including this EMP are the product of an interaction with the project design consultant, and also the product of the integrated consideration of project design and environmental protection of the sensitive sites so as to minimize the potential environmental and social impacts. To ensure an effective implementation of the EMP, the cost budget of the environmental protection measures were already included in the project cost estimate; the environmental mitigation measures were included in the technical specifications for procurement; trainings on environmental management were provided to project management staff, project implementation staff, construction supervising Consultant and contractors; and the costs on training and the implementation of the EMP were included in the overall project cost. In addition, the Client will select a qualified and experienced Environmental Monitoring Consultant (EMC) to conduct independent external monitoring. The EMC will monitor whether the contractor has implemented the environmental protection measures required in the tendering documents, assess the effectiveness of these measures, and propose suggestions for optimization of the environmental management during construction phase and operation phase. 1.1 Project Objectives The proposed World Bank financed Qinghai Xining Urban Transport Project (hereinafter “th e Project”) is located in the Xining City in Qinghai Province. The Project will utilize World Bank 4 loan of 120 million USD. The Project Development Objective is to provide rapid, comfort and safe travel service between the city center and the western urban area for the urban residents by developing a people-oriented, bus-priority and green transportation demonstration corridor. The Project will help improve the urban road network and optimize the road network structure; (2) develop a modern transportation hub and bus priority demonstration corridor; (3) strengthen the intersection channeling design and traffic management; (4) facilitate the development of intelligent traffic management system and improve the integration of bus priority and dispatching. Due to such factors as low contract award prices, poor US dollar exchange rate, use of municipal counterpart fund for civil engineering construction of public transport corridors, WB loan savings have been actually generated. In order to rationally utilize the WB loan savings, it is necessary to make a midterm restructuring of the Project. The Midterm Restructuring Project (Hereafter referred to as “MR project”) has been proposed based on the needs of urban development and construction of the Xining Municipality at the current stage. It includes improvement and expansion of urban roads, configuration of new electrical buses and their OBU monitoring equipment, and perfection of intelligent traffic management system.

The Involuntary Resettlement (OP4.12) will apply to the preparation of the Resettlement Action Plan (RAP) from which this Report will quote the results and findings. In addition, during the project identification phase, the Indigenous People (OP4.10) and the Cultural Property (OP4.11) were both applicable. Further field investigation suggested that these two policies are not applicable in following stage. However, if they were triggered during the construction phase, they will have to be followed. The other policies including the Natural Habitats, Pest Management, Forestry, Safety of Dams, Projects on International Waterways and Projects in Disputed Areas do not apply to this Project. In addition, this Project will also comply with the Disclosure of Information (BP17.50) and the Environmental, Health, and Safety Guidelines (IFC). 1.5 Environmental sensitive sites 1.5.1 Ecological Targets It was confirmed in the field investigation that there is no ecological sensitive sites in the EIA 14 scope of the MR project, such as the nature reserve, the landscape and famous scenery, the forest, the cultural heritage protection unit, or the basic farm land. 1.5.2 Ambient Air and Noise Protection Targets Under the MR project, based on the identified EIA scope, the protection targets for noise and ambient air pollution are listed in the Table 1.5-1. There are 5 sensitive targets indentified and all of them are located along the new road; within the assessment area of the Chengxi Bus Terminal , there is only 2 environmentally sensitive sites (Wangjiazhai Village and Qingtangxiao Town). There is no sensitive site near the pit ground and the spoil ground. The urban road involved in the proposed Wusi Road Bus Corridor is part of the Xining city Road Network. Along the road there are many enterprises, residential areas, hotel and different kinds of shops. The adverse impacts from the development of the Bus Corridor are mainly from the upgrade of the bus stations. In this EIA, the sensitive sites around the bus stations such as schools, hospitals and nursing homes are investigated. There are five sensitive sites identified, including the Xining Modern Maternity Hospital, the Qinghai Radio and Television University, the Qinghai Normal University, the Huangchuan High School and the Huangchuan High School No. 2 Campus. Under the MR project, noise environment protection targets within 200m along the urban roads mainly involve schools, hospitals, research and administrative office spaces and residential compounds (Hereafter referred to as “RC”) and other sensitive points. The nature, directions and impacts regarding air and noise environment protection targets under the MR project are shown in Table 1.5-3. 15 Qinghai Xining Urban Transport Project Environmental Management Plan Table 1-5.1 Noise and Ambient Air Sensitive Sites for the Roads and the Interchange Closest distance（m） Name of Positional From From Elevati Brief Road the Stake relationship Environme Photograph No. the the on description of Name sensitive No. with the ntal Impact central red differe the sensitive site sites roads line lines nce K1+800- 35 5 0 2 stories.

HAES -34- Qinghai Xining Urban Transport Project Environmental Management Plan Chapter 3 Major Environmental Impacts The proposed project will generate domestic sewage, noise and solid waste during the implementation process, which will have a certain degree of impact on the surrounding environment.This chapter will introduce the potential environmental issues and impacts caused by the proposed project during the construction phase and the operation phase from aspects including the ecological environment, the water environment, the sound environment, the ambient air, the solid waste, the accidental risks and the social impacts. 3.1 Ecological Environment (1) The project will cause certain impacts on the ecological system along the roads alignment. However, the affected plants are common species that can grow in different areas and have good adaptability. Generally the project will not cause extinction of any species within the area. Also the post-construction landscaping will offset some of the ecological loss. (2) Most of the impacts on wild animals are in the construction phase. The area of land acquisition is relatively small with similar habitats available in surrounding area, and the affected species are mostly widely distributed in many areas. The animals in the evaluation area are adaptable to human being. As most of the project area has already become populated with human activities, the wildlives dwelling in the area are adaptable to human beings. Therefore the project will not cause extinction of these animals or cause significant change in their life patterns. (3) The Xicheng Avenue will cross the Huangshui River using the new Huangshui River Bridge. The Wusixi Road will cross the Yunguchuan River by a box culvert. The Huangshui River Bridge will cross the river by one single span with no piers in the water channel. Thus the bridge construction will cause little or no disturbance to the water environment in the Huangshui River. During the construction phase, the waste water produced will not be discharged into the Huangshui River or the Yunguchuan River, therefore no impact on the aquatic lives will be cause by the wastewater. In addition, the wastewater discharge arrangement is well designed. If the operation phase wastewaters are well managed accordingly, there will be no significant impact on the aquatic lives in the Huangshui River. (4) The landscaping in the central divider and in the greenbelts on both sides of the roads will strengthen the landscape effect and add a modern feature to the roads. (5) Impacts on soil erosions: The road construction will permanently acquire some lands, destroy the original geomorphologic conditions and reduce the area of water conservation facilities. As the top soils or vegetations are damaged in the excavation, or buried, the nature of land use will permanently be changed, causing the loss of land resource. The construction waste will be stored at temporary spoil field. If no effective measures are taken, the loose soil pile will cause erosions in storm occasions and become silted in HAES -35- Qinghai Xining Urban Transport Project Environmental Management Plan surrounding farmlands and ponds. During dry weathers, it may also become flying dust and damage the regional environment. The damage to vegetations will also cause damage to the integrity of the landscaping. The road construction activities will cause an increase in the soil erosion coefficient. As the amount of newly added soil erosion is huge, it will cause an increase in the suspended solids in the water can cause damage to the water storage capacity and the water quality. The nutrient in the soil erosion will also cause nutrient pollution as a non-point source. At the same time, as large amount of soil and sand enters the irrigation system in the project area, the irrigations trenches might be clogged and the irrigation system might not function normally. 3.2 Water Environment 3.2.1 Construction phase The wastewaters are mainly from the domestic wastewater of the construction workers and the wastewater construction (1) In the construction camp, only very simply living facilities are provided and the wastewater amount produced will be small. The wastewater will contain organic matters such as fats, food residues, detergents, etc. If the wastewater is discharge directly without any treatment, it will cause adverse impact on the surface water bodies in the surrounding area. (2) The construction wastewaters are mainly from the wastewater for cement mixing, and the wastewater for machines or vehicles cleansing and maintenance. The process water of concrete manufacturing is mainly for cleansing of sand material and for cement mixing. The wastewater has high turbidity and high sand content. The washing of machineries and vehicles will produce a large amount of wastewater with high sand content. According to similar project experiences, the major pollutants for construction wastewater are COD (50-80mg/L), oil (1.0-2.0mg/L), and SS (150-200mg/L).These wastewaters can cause water pollution; therefore they are not allowed to be discharged to the water bodies along the roads directly. The construction wastewater will be recycled after oil separation and sedimentation processes. They are not allowed to be discharged into the Huangshui River or into the Yunguchuan River. (3) According to the Xining Water Environment Function Zoning Plan, the Huangshui River is a Class III water body near the crossing location, and the Yunguchuan is a Class II water body near the crossing location. Both of them are drinking water source protection areas. If the construction wastewater is discharged into the Huangshui River or the Yunguchuan River directly, it will impact on the water quality and on the water body functions. Therefore it is required that the construction wastewater be recycled after treatment instead of being discharged into the water body. If this requirement is followed, the impact on the water quality will be insignificant. 3.2.2 Operation phase The urban road wastewaters during operation phase will cause a certain degree of wastewater. HAES -36- Qinghai Xining Urban Transport Project Environmental Management Plan (1) The wastewater from the roads during operation phase is mainly composed of the storm water. The major pollutants include the SS and the COD. According to the analogy estimation, the discharge intensity and the annual load of COD are relatively small. They are within the self purification capacity of the water body. Therefore the road runoff will not cause significant impact on the water environment. (2) The roads to be constructed in this Project are mainly urban roads that do not allow transportation of hazardous chemical. Therefore there is no risk of water pollution caused by accidents of vehicles loaded with hazardous or poisonous substances. However, consider that traffic accidents can lead to oil spill and contaminate the water environment, it is recommended that a runoff collection system on the bridge surface and sedimentation tanks on the both ends should be arranged to collect and treat the surface runoff after the traffic accident. 3.3 Sound Environment 3.3.1 Construction phase During the earth works, when a single machine is being used, the noise level at 60 meters distance will be below 70dB(A) (the day time limit of the Noise Limits of Construction Sites), and the noise level at 300 meters can be below 55 dB(A) (the night time limit of the Noise Limits of Construction Site). During the structural works, the noise level at 40 meters distance will be below 70dB(A) (the day time limit of the Noise Limits of Construction Sites), and the noise level at 200 meters can be below 55 dB(A) (the night time limit of the Noise Limits of Construction Site) There are five sensitive residential sites along the roads, including the Taobei Village, the Wangjiazhai Village, the Zuoshu Village, and the Wuzhong Village. All of these four sites are located within 3-200 m distance away from the roads. The construction activities will cause different level of noise impact. It will exceed the noise limit by 3-14 dB(A) during day time and 2-24 dB(A) at night time. 3.3.2 Operation phase (1) The prediction results of the traffic noise along the roads. 1) The Wusixi Road Short term: During the day time, the noise levels for areas outside the red lines can comply with the Class 4a standard of the Quality Standards of Sound Environment (GB3096-2008).

While during the night time, the noise level of the areas that are 69 meters away from the central line can comply with the Class 2 standard of the Quality Standards of Sound Environment (GB3096-2008). For the long term, both in the day time and in the night time, the noise levels for areas outside the red lines can comply with the Class 4a standard of the Quality Standards of Sound Environment (GB3096-2008). During the day time, the noise levels for areas outside the red lines can comply with the Class 2 standard of the Quality Standards of Sound Environment (GB3096-2008). While during the night time, the noise level of the areas that are 16 meters away from the central line can comply with the Class 2 standard of the Quality Standards of Sound Environment (GB3096-2008). From the table, the noise level compliance distances are within the scope of evaluation. In real situation, because of different factors including the terrain absorption, building absorption, vegetation absorption and air attenuation, the actual noise level will be lower than the predicted theoretical values. (2) The prediction results of the traffic noise at the sensitive sites. For the short term (by 2018) the noise levels at the sensitive sites are all below the limits. For the Midterm (by 2024), the noise levels at the Zuoshu Village and the Wuzhong Village along the Xicheng Avenue and at the Taobei Village along the No.5 Road are all below the limits. For the Taobei Village along the Wusixi Road and the Wangjiazhai Road along the Xicheng Avenue, the noise levels during day time are below the limits. But they are all above the limits at night times. They exceed the limits by a range of 1.1-5.1 dB (A). For the long term (by 2032), the noise levels at the Wuzhong Village along the Xicheng Avenue HAES -39- Qinghai Xining Urban Transport Project Environmental Management Plan and at the Taobei Village along the No.5 Road are below the limits. For the other three sensitive sites, the noise levels are below the limits during day time but exceed the night time limits by 1.8 to 6.7 dB(A). (3) The prediction results of the traffic noise near the Bus Corridor. The traffic flow will not change significantly after the upgrading as the red line width will not change. The bus speed will increase significantly. As the traffic can move more smoothly, the traffic noise will decrease compared with that on a congested road with vehicles engines idle running. In addition, the upgraded bus service will provide more convenience for the local travel and will attract more and more people to adopt the public transportation. The use of private cars will be reduced. So is the source of pollution. With a comprehensive consideration of above factors, it is predicted that the environmental noise on the road side will remain unchanged. 3.4 Ambient Air 3.4.1 Construction phase (1) In a windy occasion, the mixing of construction material will produce TSP pollution. According to the monitoring data of similar projects, the TSP concentrations at 50m, and 100m distances downwind from the mixing stations are 8.90 mg/m³, 1.65 mg/m³. At the 150 m distance downwind from the mixing stations, the TSP concentration will be below 0.3 mg/m3, the limit stipulated by the Class II standard of the Quality Standards of Ambient Air (GB3095-1996). The TSP produced in other processes can be contained within the distances of 50-200 meters from the construction sites. Outside of this range, the TSP concentration can meet the Class II standard of the Quality Standards of Ambient Air (GB3095-1996). (2) The loading/unloading and the transportation of construction materials can also produce TSP pollution. According to the monitoring data of similar projects, the TSP concentrations at 50m, 100m, and 150m distances downwind from the transportation routes are 11.652 mg/m³, 9.694 mg/m³, and 5.093 mg/m³, respectively, all exceeding the Class II standard of the Quality Standards of Ambient Air (GB3095-1996). Above analysis suggests that the dust pollution and the TSP pollution are significant and need appropriate mitigation measures. 3.4.2 Operation phase (1) Based on the prediction results, the hourly NO2 concentrations for all the reference years including 2018, 2024 and 2032 at the 5 sensitive sites (including the Guanzhong Village, the Wangjiazhai Village, the Zuoshu village, the Taobei Village, and the Yanxiaocun Village) all exceed the standard limit required by the Class II standard of the Quality Standards of the Ambient Air (GB3095-1996 and GB3095-2012). While the hourly CO concentrations for all the reference years (including 2018, 2024 and 2032) at the 5 sensitive sites (including the Guanzhong Village, the Wangjiazhai Village, the Zuoshu village, the Taobei Village, and the Yanxiaocun Village) are all below the standard limit required by the Class II standard of the Quality Standards of the Ambient Air (GB3095-1996 and GB3095-2012). The daily NO2 concentrations for all sensitive sites exceed the standard limit required by HAES -40- Qinghai Xining Urban Transport Project Environmental Management Plan the Class II standard of the Quality Standards of the Ambient Air (GB3095-1996 and GB3095-2012). The daily CO concentrations at the Guanzhong Village, at the Zuoshu Village, at the Taobei Village and at the Yanxiaocun Villages in 2032 exceed the standard limits; the daily CO concentrations for other occasions are all below the standard limit required by the Class II standard of the Quality Standards of the Ambient Air (GB3095-1996 and GB3095-2012). The yearly NO2 concentrations at the Wangjiazhai Village, at the Zuoshu Village, at the Taobei Village and at the Yanxiaocun Villages in 2024 and in 2032 exceed the standard limits, the yearly NO2 concentrations for all other occasions are all below the standard limit required by the Class II standard of the Quality Standards of the Ambient Air (GB3095-1996). However if the new Quality Standards of the Ambient Air (GB3095-2012) is applicable, then all the concentrations will exceed the Class II standard limits. (2) The traffic flow will not change significantly after the upgrading as the red line width will not change. The bus speed will increase significantly. However, as the traffic move smoothly, the pollutants from the exhaust gas will decrease. In addition, the updated bus service will provide more convenience for the local travel and will attract more and more people to adopt the public transportation. The use of private cars will be reduced. So is the exhaust gas emission. For the bus stations and the Interchange, the normal operation will not cause significant impact on the ambient air environment. (3) After the construction is completed and the traffic flow increases, the exhaust gas emission will also increase, leading to an increase in PM2.5 concentration and an adverse impact on the air quality. 3.5 Solid Waste 3.5.1 Construction phase The solid waste mainly comes from the earth works, the building demolishing, and the domestic solid wastes. According to the engineering design, it is estimated that the excavation volume will be 374,800 m3, the fill volume will be 275,700 m3 and the waste earth volume will be 99,100 m3. The waste will be mainly top soil (97,300 m3) which will be temporarily stored up for future landscaping use and bridge foundation construction waste (1,800 m3) which will be sent to landfills for disposal. According to the Resettlement Action Plan, there will be buildings of 150,261.15 m² floor area demolished which will produce construction waste of approximately 168,800 tons. This waste will be transferred to a proposed Xining Chengbei District Wuzhongdagou Landfill for treatment. It is estimated that there will be 100 workers on site at peak period and producing 0.1 tons of domestic waste per day. The construction phase solid waste will be linearly distributed along the roads. If not well stored or handled, it could damage the vegetation along the roads, clog the irrigation ditches, or fall into the Huangshui River, Yungguchuan River or the ponds and consequently pollute the water bodies. If the solid waste is stored for too long, it could also cause flying dust on windy days, and cause impact to local residents. Therefore, construction management should be strengthened to clean up the solid waste promptly to reduce or prevent the above mentioned impacts. HAES -41- Qinghai Xining Urban Transport Project Environmental Management Plan The domestic waste such as the food residue, the plastic packaging, the waste cells, can cause adverse impact on the city appearance and cause environmental pollution if not well handled. In addition, if the domestic waste is not well managed, it can attract rodents and mosquitoes which can also pose a threat to the workers’ health. The domestic waste will also produce highly concentrated leachate, which can cause further pollution to the soil and the water. When the domestic waste contains waste cells, it can cause contamination of heavy metals, making the pollution even worse. 3.5.2 Operation phase During the operation phase the solid wastes are mainly from the domestic waste produced by the pedestrian along the roads. In not properly handled, the solid waste can have an adverse impact on the landscape and the public hygiene, and can also pollute the air and pose a threat to public health. During the operation phase, the solid waste will be handled by the municipal solid waste management system. It will be sorted and collected using the garbage bins placed on both sides of the roads. The solid wastes that cannot be recycled will be sent to the sanitary landfills for disposal. 3.6 Accidental Risk There are two kinds of accident risks in this project, including the traffic accident risk. The proposed roads in this Project are mainly urban trunk roads that do not allow hazardous chemical transportation. The transportation of such chemicals will take the route of the branch roads at the south end of the city. Therefore, there is little or no risk of water pollution from traffic accidents with vehicles carrying poisonous or hazardous substances. However, there is a potential risk of that the management is not well enforced, or that the vehicle drivers make a mistake. In either case, collisions or rollover of vehicles might occur and pollute the environment. A lot of studies show that most of pollution accidents along the roads are caused by traffic accidents. When the roads are near a water body, these accidents might lead to water pollutions. However, though the possibility of a traffic accident is low, if such accident occurs, the consequence can be positive. 3.7 Social Impact (1) Positive Impact This Project can help improve the urban road network and facilitate the development of the transportation hub; it can improve the urban development and ensure the sustainable development; and it can facilitate the economic development, improve the investment environment and improve the living condition. (2) Adverse Impacts 1) The Project will involve some demolishing and resettlement of enterprises or residential houses and brings in adverse impact on the local enterprises and residents. 2) The project will occupy the land of local residents and causing loss to local farmers. Therefore it is necessary to include the local residents suffering loss into the social security system and ensure their normal life and work. In addition, preference should be given to these people suffering loss for employment placement. The Project will have certain impact of the traffic safety, especially for residents of the three villages including the Taobei Village, the Wangjiazhai Village, and the Zuoshu Village. After the Project is complete, the HAES -42- Qinghai Xining Urban Transport Project Environmental Management Plan traffic flow will increase, brings in more traffic safety risk to the area. For some sections, facilities such as the traffic lights, the zebra crossing, or the overpass should be established. 3) The Project will have certain impact of the traffic safety, especially for residents of the Taobei Village, the Wangjiazhai Village, the Zuoshu Village, and the Wuzhong Village. After the Project is complete, the traffic flow will increase, brings in more traffic safety risk to the area. For some sections, facilities such as the traffic lights, the zebra crossing, or the overpass should be established. 4) There are many sensitive sites along the Bus Corridor on the Wusi Road, including the enterprise and institutes, residential areas, hotels and shops. The construction for the bus stations upgrade will increase the pressure on local traffic and induce more traffic accidents. The construction will cause adverse impacts on the operation of local enterprises and institutes, the travel of local residents and the business operation of local shops. However, the construction period for bus stations upgrade is very short. After the construction is completed, the impacts will expire too. 5) The Xicheng Avenue undercrosses the Qinghai-to-Tibet Railway in the form a jacked-in frame bridge. Improper construction method may interrupt the normal operation of the railway. The falling gravel will cause safety concern of the construction workers and the vehicles using the undercross. 3.2 Environmental Impact Analysis of the MR Project 3.2.1 Forecast & Evaluation of Environment Impact Analysis during the Construction 3.2.1.1 Impact Analysis of Atmospheric Environment No concrete mixing station and asphalt mixing station are set at construction sites. The concrete and asphalt required for the project are all purchased by outsourcing. Therefore, the main air pollution sources during the construction period are: flying dust generated by excavation at the construction site, road dust from loading and unloading of construction materials or earthwork, and transportation, asphalt smoke produced by road paving and exhaust emissions of fuel-powered construction machinery and transport vehicles. （1）Flying Dust Loose particles of earth and rock excavation as well as sand and gravel yard form the source of flying dust pollution. In the course of material handling and transport, there appears secondary flying dust, affecting ambient air quality of the roads and their both sides. Without taking any protective measures, the TSP concentration in the wind direction at the construction sites rapidly decreases with increasing distance, and its concentration is basically stable after about 40m. Its affected scope shall be rated according to Level 2 criteria of the Ambient Air Quality Criteria (GB3095-2012) (standard daily average value of TSP: 0.3mg / m³) . The criterion shall be up to 50m away. After sprinkling construction sites, it can have an obvious effect of suppressing TSP on the construction sites. At about 35m downwind, the daily TSP concentration has dropped below the standard value. It can be seen that timely sprinkling at the construction sites to ensure the wetting of the construction sites is conducive to suppressing generation of dust on the construction sites, which can effectively reduce the impact of flying dust on the HAES -43- Qinghai Xining Urban Transport Project Environmental Management Plan surrounding environment. According to the site investigation, there are a number of sensitive protection targets surrounding the urban roads, like the Xining Jiaojindadui RC, the Jinwei Building, Wuzi Gongxiao Gongsi RC and the Qiyi RC. They are located at the nearest distance of 20m from the red line of proposed works, with great impacts of constructional flying dust. In order to reduce impacts of flying dust from construction sites and vehicle transportation on the surrounding environment, the implementing unit and the construction unit should do a fine job in carrying out air pollution prevention & control work during the construction period as required by relevant regulations of the Xining Municipality, such as setting enclosure, standardization of stacking of powder materials and vehicles transportation, regular watering, timely slag removal and so on. （2）Waste Gases of Asphalt Paving Since commercial asphalt shall be purchased from outside, the project does not have any asphalt mixing station. As a result, waste gases mainly come from asphalt pavement and maintenance. When asphalt is compacted by a road roller and subjected to about 10 minutes of natural cooling, asphalt mixture temperature will drop below 82 ℃, asphalt smoke will be significantly reduced. With asphalt solidification, asphalt smoke will disappear immediately, thus having less impact over the surrounding environment. Commercial alphalt concrete procured outside shall be transported by special vehicles with canned asphalt in order to prevent scattering and dropping along the roads from polluting the environment. 3.2.1.2 Impact Analysis of Surface Water Environment During the construction period, project impacts on the surrounding water environment mainly include construction wastewater and domestic sewage. (1) Construction Wastewater The project construction sites will not be provided with maintenance yards, and all mechanical maintenances shall take place to professional repairing shops. The construction wastewater is mainly mechanical and vehicular wastewaters. Such wastewater contains a large amount of silt and the stuff, with a high concentration of suspended particles, weakly alkaline PH value and a small amount of dirty oil. According to analogy investigation, the concentration of suspended particles is generally in the range of 1000-5000mg/l, with petroleum <10 mg/L. After oil separation and sedimentation, the wastewater can be recycled without being discharged. Since the project construction sites are relatively concentrated, the EIA requires that temporary sedimentation ponds, grease traps be built on temporary working sites. The equipment rinse water after grease separation enters the temporary sedimentation tanks for oil separation or precipitation. After more than 12 hours of sedimentation, the main pollutant - SS in the wastewater can be reduced to less than 200 mg / L. The wastewater can be recycled, for example, for equipment flushing, water-sprinkling for dust suppression, HAES -44- Qinghai Xining Urban Transport Project Environmental Management Plan instead of being directly discharged into the Nanchuan River and the Huangshui River Through the strict treatment of wastewater, it will have a small impact on the surface water of the river. (2) Domestic Sewage During the construction, construction workers will produce a certaint amount of living sewage. For living sewage of construction workers, like similar scale of construction, during peak hours, there are about 100 people per day on construction sites. According to 50L water meter and domestic wastewater discharge coefficient of 0.80 meter per person / per day, the maximum domestic sewage generated by construction workers shall be 4.0m³/d, with a characteristic pollutant concentration of COD 300 mg/L and ammonia nitrogen 30 mg/L. According to the characteristics of social environment along the urban road, the project is located in the urban areas of Xining Municipality. Its drainage status along the roads belongs to the Xining No. 1 Sewage Treatment Plant. The project construction sites shall be equipped with counterpart septic tanks and drainage pipelines, which can be connected with the municipal sewage pipe network. The construction domestic sewage shall enter the septic tanks and then be discharged into sewage pipelines the Xining No. 1 Sewage Treatment Plant for treatment. 3. 2.1.3 Impact Analysis of Acoustic Environment (1) Noise of Construction Machinery The noise during the construction mainly comes from construction machinery and vehicles for construction and transportation, of which it is based on that from constructional equipment. It is noted that construction machinery mainly includes excavators, bulldozers, road rollers and loaders. During the construction period, the Ambient Noise Emission Criteria for Building Construction Sites (GB12523-2011) shall be implemented. In the absence of obstruction, for a single machine in operation, the construction machinery should meet the criteria of 70dB(A) in the daytime at 60m away from the construction site and 55dB(A) at night at 200-300m away from the construction site according to the "Ambient Noise Emission Criteria for Building Construction Sites" (GB12523-2011) . In the actual construction process, often multiple machines work at the same time, radiations from various noise sources overlay each other, with higher noise level and greater radiation range. According to the field survey under the MR project, there are a large number of densely distributed residential areas, hospitals and schools near the physical works along the Qiyi Road, the Wuyi Road and the Changjiang Road, such as Taiheyuan RC, Qingying Linxiucheng RC, Huaningyuan RC, Xining No.1 Middle School and Xining Xiaoquan Primary School. Daytime and night construction will interfere with the normal living of the above-mentioned residential compounds, in particular, with greater noise impact at night. Corresponding measures for protection and management should be taken. For example, at night (22:00 ~ 6:00) and residents lunch break (12: 00-14: 00), construction activities are banned; it is wise to select low-noise construction machinery; construction and transport vehicles are run at speed limit; no horning is made for transport vehicles in residential areas. HAES -45- Qinghai Xining Urban Transport Project Environmental Management Plan By adopting the above measures, the impact of construction noise on residents will be reduced. With the completion of the project, the impact of construction noise will no longer exist. The adverse impact of construction noise on the environment will be temporary and immediate. (2) Noise of Traffic Transportation During the transportation of construction materials such as commercial asphalt concrete and abandoned spoils or slag from construction, the noise of transportation vehicles will affect the noise sensitive points on both sides of transportation roads. According to the analogy test, the sound levels is 82-88dB (A) at the distance of 7.5m away from the truck, 79-85dB (A) at 10m away and 72-78dB (A) at 30m away. When the transport vehicles pass, residential areas within the range of 50m along the urban roads will be more or less affected. 3.2.1.4 Impact Analysis of Solid Wastes During the project construction period, solid wastes mainly iclude abandoned earthwork and demolished constructional debris and domestic garbage of construction workers. (1) Abandoned Earthwork and Construction Waste The project has a total amount of wastes of 27,300 m³, all of which are permanently discarded. They mainly include spoils of original pavements, and unused and unallocated surplus earthwork after pipeline ditch excavation. The abandoned spoils or slags from the project shall be uniformly shipped to the Najiashan Zhengyuan Company Commercial Slags Disposal Site. During the process of excavation and backfilling of the drainage pipeline network and the common utility tunnels, there will be temporary earthwork for backfilling of pipe ditches in the MR project. Because of long pipelines, scattered layout and short construction period, the earthwork should not be piled up in a centralized way. The backfilling earthwork at the later stage of trench excavation shall be temporarily heaped up alongside the trench and there will be no separate storage site for soil dumping. (2) Living Garbage of Construction Workers During the construction peak hours, there will be about 100 workers on the sites, for living garbage of construction workers, at the rate of 1.0kg/person·d, the maximum daily garbage discharge shall be about 0.1t. The living garbage of construction workers shall be collected and handed over to the sanitation department for disposal, thus having no obvious impact over the surrounding environment. 3.2.1.5 Ecological Impact Analysis (1) Impacts on Animal and Plant Resources Located in the built-up areas of the Xining City, the project is an improvement or expansion of existing urban roads. The project land occupation is of highway land type. HAES -46- Qinghai Xining Urban Transport Project Environmental Management Plan According to the field reconnaissance, within 200m along the urban roads like the Qiyi Road, the Bayi Road and the Wuyi Road, the types of vegetation mainly include artificial arbors and shrubs and other locally common species. Currently, there are livestock and poultry such as dogs, cats within the EIA scope. The construction of the project shall take place along the existing urban roads, thus its construction activities are mainly concentrated within the scope of the roads, thus causing no damage to the current greening spaces along the urban roads. Meanwhile, ecological tree ponds of 464 m² shall be built, thus faciliting the construction of road landscape. (2) Impacts on the Urban Ecological Landscape The project falls into the category of road reconstruction and expansion. The ecological environmental impact during the construction period is mainly reflected in the impact over the urban ecological landscape. It mainly involves the following aspects are: 1) In the process of project construction, it will have a certain adverse effect on local urban appearance and urban landscape. However, this effect is temporary and will disappear after the construction is completed. Additionally, through the improvement of road greening, the city landscape will be beautified. 2) During the construction, foundation excavation, earthwork and construction materials stacking, especially piled construction spoil will affect the city's sanitary environment and urban landscape. If the spoil is piled up casually, flying dust will pollute pavements and houses in sunny days, thus having a great impact on the surrounding environment and residents. In rainy days, rainwater will scour earthwork and sediments will enter the municipal pipeline system or the Nanchuan River, causing congestion or blockage. The construction units should timely transport and dispose of slag, while leaving some space to temporarily spoil dumping. There is also need to adopt counterpart measures to reduce its environmental impacts. 3) Disorderly parking of some mechanical equipment during the construction process may also bring about uncoordinated factors and impacts to the surrounding landscape. 4) Located in the built-up areas of the city, the project is an improvement and expansion of the original urban roads, the lands for construction sites and temporary spoil dumping sites shall be the overlapping areas of main works. The project construction will not change the original land utilization function, with less disturbance of land surface. In conclusion, the project construction will neither change the existing land use pattern along the urban roads nor exacerbate the tension of land resources along the lines. Meanwhile, after the implementation of greening measures, the area of green land along the routes will increase, thus contributing to the beautification of the surrounding environment and enhancing the overall image of the city. 3.2.2 Forecast & Evaluation of Environmental Impact during the Operation 3.2.2.1 Impact Analysis of Atmospheric Environment HAES -47- Qinghai Xining Urban Transport Project Environmental Management Plan During the operation period, pollution of ambient air mainly comes from flying dust pollution and exhaust pollution generated by vehicles passing. Based on the forecast results in the EIA, it can be seen that the maximum hourly concentration, the maximum daily concentration and the annual average concentration of NO2 and CO in the regional grid prediction points can meet level 2 standard limits in the Ambient Air Quality Criteria (GB3095-2012). Therefore, NO2 and CO generated during the project operation will not cause obvious adverse impacts on the regional environment. In terms of pollutants concentration, all sensitive points can meet level 2 standard limits in the Ambient Air Quality Criteria (GB3095-2012). In the meanwhile, after the implementation of bus priority corridors works, bus speeds will be significantly increased, the bus exhaust emissions will be lower than those of idle vehicles, thus improving the quality of ambient air to some extent on both sides of the streets. In addition, with the constant convenience of public service, an increasing number of citizens will be enticed to choose the travel means of public transport while the number of trips of private vehicles and taxies will be reduced, with decreased amount of vehicle exhaust transmission. 3.2.2.2 Impact Analysis of Noise Environment Forecast evaluation shall be carried out for the near-term period (2019), the intermediate period (2025) and the long-term period (2033) of the project Operation. 1) Forecast of Road Traffic Noise For the project road traffic noise, consideration is given to noise reduction effect (5 dB(A)) using SMA low-noise road surface instead of blocking and reflecting actions of buildings on both sides of the urban roads. Under the condition of reflection, noise up-to-standard distances of category 4a, category 2 and category 1 areas in the short-term, intermediate and long-term project periods are as follows: The Qiyi Road (Jianguo Rd – Delingha Rd): for category 4a, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all within the road borderline and its night up-to-standard distances are <10m from the road borderline; for category 2, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all <10m, and its night up-to-standard distances are 12m, 14m and 15m respectively; The Delingha Road (Qiyi Rd - Bayi Rd): for category 4a, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all within the road borderline and its night up-to-standard distances are <10m from the road borderline; for category 2, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all <10m, and its night up-to-standard distances are 10m, 10m and 13m respectively. The Bayi Road (Delingha Rd - Huangzhong Rd): for category 4a, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all within the road borderline and its night up-to-standard distances are <10m from the road borderline; for category 2, its day up-to-standard distances in the short-term, intermediate HAES -48- Qinghai Xining Urban Transport Project Environmental Management Plan and long-term periods of project operation are <10m, <10m and 12m respectively and its night up-to-standard distances are 13m, 19m and 25m respectively. The Wuyi Road (Qiyi Rd - Binhenan Rd): for category 4a, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all within the road borderline and its night up-to-standard distances are <10m from the road borderline; for category 2, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are all <10m, and its night up-to-standard distances are 12m, 13m and 14m respectively; for category 1, its day up-to-standard distances in the short-term, intermediate and long-term periods of project operation are 34m, 35m and 36m respectively, and its night up-to-standard distances are 29m, 30m and 32m respectively. 2) Forecast of Noise at Sensitive Points The forecast results of environmental noise of sensitive points show that daytime noise at sensitive spots can all satisfy the requirements regarding their corresponding criteria as specified in the "Acoustic Environmental Quality Criteria" (GB3096-2008) in the near term (2019), mid-term (2025) and long term (2033) of the project operation period. Night Noise: During the project operation period, at most of sensitive points, noise at night along the urban roads can meet the corresponding standard requirements as indicated in the "Acoustic Environmental Quality Criteria" (GB3096-2008). at the first row of near-road few sensitive points, night noise is slightly over standard. According to the statistics, in the long-term (2033) of the project period, for Ganxiusuo RC (Floors 2,4 of near-road row-1 buildings), night noise will exceed 0.8 ~ 0.9 dB (A); for the Qinghai Shen Meitan Wuce RC (Floor 3 of near-Bayi-Road row-1 buildings), night noise will exceed 0.4 dB (A). 3.2.2.3 Impact Analysis of Water Environment The project itself does not produce domestic sewage, but only road surface runoff. The main pollution factors of road surface runoff are SS and COD. According to experimental data of runoff pollution of road surface of relevant line agencies in China, the concentration of pollutants in the rainwater of pavement undergoes the process of descending from large to small. the concentration of pollutants reaches the maximum within 0-15 minutes and then decreases gradually. After the rainfall lasts for 40 minutes , the road surface is basically washed clean, and the concentration of road surface runoff pollutants is relatively stable at a low level. Under normal conditions during operation, COD emission intensity and annual pollution load are relatively small, and pollutants can be basically eliminated by the purification function of the water body. Therefore, after the completion of this project, rainwater on the road will not obviously affect the water environment . This project targets the urban roads, and dangerous goods transportation is not allowed within the range of the urban roads. Therefore, there is no risk of polluting water body caused by traffic accidents of vehicles loaded with toxic and hazardous substances in this project. 3.2.2.4 Impact Analysis of Solid Wastes During the operation period of urban roads, transport materials scattered by vehicles or HAES -49- Qinghai Xining Urban Transport Project Environmental Management Plan spilled by vehicles with traffic accidents, rubbish discarded by passengers shall be supervised and cleaned up through environmental sanitation agencies. After garbage collection, there will be no adverse impact over the surrounding environment. Electric buses purchased under the component of public transportation infrastructure are driven by lithium-ion battery. The resultant used battery shall be returned to electric bus manufacturers for recycling, which will not adversely affect the surrounding environment. 3.2.3 Risk Analysis of Environmental Accidents This project is designed for the existing urban roads. According to the "Xining Municipality Master Urban Plan (2001-2020)" (revised in 2015), the land plots along the project urban roads is mainly used for residential areas, commercial service facilities land, administrative offices, schools and scientific research institutes . Transportation of dangerous goods will not be allowed within the scope of the project roads. Therefore, there is no risk of polluting the water bodies due to traffic accident risk of vehicles loaded with toxic or hazardous substances. 3.3 EIA Analysis of Wangjiazhai Interchange (Chengxi Bus Terminal) The new site of the Wangjiazhai bus terminal is located at the northeast corner of intersection between Xicheng Avenue and Wusixi Road which are both new constructed roads under the project. Current site is flat farmland and wasteland, with no buildings or structures. There is no sensitive environmental and social protection objectives at the site. 3.3.1 EIA Prediction and Analysis during Construction 3.3.1.1 Air Impact Analysis （1）Flying Dust Based on the prediction, in the absence of any dust-proof measures, construction sites will have a serious impact on the surrounding environment. The TSP concentration in the 110m range exceeds the Class II standard limit of Standards of Ambient Air Quality (GB3095-2012); with water-spraying measures taken, the TSP concentration value at about 35m from the construction site can reach the TSP daily average Class II standard of the Standards of Ambient Air Quality Standard (GB3095) in Table 2. According to the field visit survey, there are residential areas such as Wangjiazhai Village and Qingtangxiao Town in the vicinity of the project area, with the nearest distance of about 50m. Therefore, in the case of dust-proof measures, the construction dust has little impact on it. （2）Impact Analysis of Construction Machinery Tail Exhaust Gas Various construction machinery used in construction (such as trucks, forklifts and bulldozers) generally use diesel as fuel. The fuel smoke gas is directly discharged at the site. The main pollutants include HC, SO2, NO2 and soot. The construction agency shall use transportation vehicles and construction machinery that discharge pollutants in accordance with national standards, strengthen the maintenance of equipment and vehicles, and keep machinery and vehicles in good working condition. It is HAES -50- Qinghai Xining Urban Transport Project Environmental Management Plan strictly forbidden to use scrapped vehicles and out-of-service equipment to reduce the the impact of construction machinery exhaust gas on the surrounding environment. （3）Impact Analysis of Decoration Exhaust Gas The decoration exhaust gas generated during the construction period consists mainly of the dust generated by exterior wall decoration and interior decoration exhaust gas. As the amount of dust generated by the decoration is very small, it will completely disappear with the end of the construction period. Plywood, coating paint, oil paint and other decorative materials that may be used in the interior decoration process contain a certain amount of volatile toxic gases such as formaldehyde, benzene, toluene, etc. If the concentration exceeds its corresponding standard, it will cause a local impact on indoor air quality. 3.3.1.2 Impact Analysis of Surface Water Enivronment （1）Waste Water during Construction The project construction sites are not provided with machinery maintenance points. For mechanical maintenance, all machinery will have such service at professional maintenance points. The construction wastewater is mainly from mechanical and vehicle cleaning wastewater. Such wastewater has a high concentration of suspended solids, with a pH that is weakly alkaline and a small amount of oil. （2）Domestic Waste Water of Construction Workers Domestic sewage mainly comes from dirty water and fecal water generated by the daily living of construction workers. A construction camp is set up for the construction of the project. About 50 people will be on site during the construction period, with domestic sewage of 4.5 m³/d. The main pollutants in the domestic sewage of construction workers are COD, ammonia nitrogen, animal and vegetable oil, etc. If discharged directly without treatment, it will adversely affect the water quality of the surrounding surface water. 3.3.1.3 Impact Analysis of Accoustic Environment （1）Accoustic Compliance Analysis at Construction Site Boundary The noise sources during the construction period mainly come from noises such as excavators, bulldozers, scrapers, oscillators, pile drivers, diesel generators, chainsaws, grinding machines, welding machines and equipment transportation. According to the prediction, when multiple machines are being constructed at the same time, in the earthwork stage, beyond 80m in the daytime and 300m at night, the noise standard of the construction site boundary can be met; in the stage of decoration and structuring, beyond 100m in the daytime and 400m at night, that of the construction site can be satisfied. According to the analysis of the plane layout of the project, it can be seen that in the absence of measures, the eastern, western, southern and northern fields cannot meet the standard value of the Environmental Noise Emission Standard for Construction Sites (GB12523-2011) at night. The eastern and western fields can reach the standard in the daytime, whereas the fields on both sides of the south and the north exceed the standard. The Qingtangxiao Town around the project is about 50m away from the boundary of the HAES -51- Qinghai Xining Urban Transport Project Environmental Management Plan project, and the Wangjiazhai Village about 280m away from the project boundary. The noise sensitive points are all within 300m. During the day, the construction will have different degrees of impact on the residents' buildings, especially the first row of residents' buildings. At night, the impact on residents' rest is particularly obvious. Therefore, measures must be taken to strictly prohibit night construction and minimize the impact of construction noise on environmental protection objectives. 3.3.1.4 Impact Analysis of Solid Wastes （1）Abandoned Earth and Construction Waste The abandoned earthwork generated by the project is mainly the spoil generated by excavation of foundation and basement. The construction waste mainly includes construction waste and garbage generated by decoration. If the spoil and construction waste generated by the project construction are not properly disposed of but piled up randomly, they will not only occupy land resources, but also cause dust to be polluted on windy days, causing environmental air pollution. When it rains, they will easily cause soil erosion and affect urban landscape. The abandoned earth and stone and construction waste generated by the construction of this project shall be carried away to the construction waste disposal field of Xixingyuan in Chengbei District. （2）Domestic Waste At the peak of construction camp construction, there will be about 50 construction workers on site, and the daily construction of domestic garbage generated by the project will be about 0.05t. The domestic garbage of construction workers will be collected and transported to the sanitation department for disposal. 3.3.2 IEA Prediction and Analysis during Operation 3.3.1.1 Impact Analysis of Air Quality （1）Automobile Exhaust Gas at Parking Lot Automobile exhaust mainly refers to the exhaust emissions of vehicles in the parking lot/garage and when driving in the parking lot and garage, including pipe exhaust, crankcase gas leakage, fuel tank leakage. The main pollution factors in automobile exhaust gas are CO, HC, NOx, ect. According to engineering analysisand calcuation, the CO, HC and NOx emissions of the project parking lot are 5.90t/a, 1.18t/a and 1.56t/a respectively. （2）Kitchen Soot Exhaust Gas The restaurant adopts a fume purification facility that has been tested by agency identified by the government authorities. The fumes are purified and treated by a built-in special smoke flue (1.5m above the roof), with a fume purification efficiency >85%, and a soot emission concentration of about 1.65mg/m3, and an emission of soot is 15.84kg/a. it is characterized by small emission and short period. It can meet the medium-sized requirements of the Standards of Soot Emission of Catering Industry (GB18483-2001). Therefore, the exhaust emission of soot will not affect the surrounding air. （3）Exhaust Gas for Boilers HAES -52- Qinghai Xining Urban Transport Project Environmental Management Plan The boiler chamber of the project shall use two 5.6W vacuum hot water boilers, driven by natural gas as fuel. According to the feasibility study, the natural gas consumption of the boiler house is 2.07 million m3/a. As natural gas serves as a kind of clean energy, the boilers under the project have fewer pollutants. It is calculated that the emission concentrations of soot, SO2 and NOx in flue gas from natural gas boilers are 13.7mg/m³, 29.4mg/ m³ and 137.3mg/ m³ respectively, with their emission about of 0.39 t/a, 0.83 t/a, and 3.87 t/a respectively. The boiler exhaust gas passes through the special flue to the top of the apartment building (No. 1 Building) and it is discharged 1.5m above the roof (the discharge port is 40m above the ground), which meets the gas boiler emission standard limits required by the Standards of Boiler Air Pollutant Emission (GB13271-2014) in Table 2. Specifically, they are 20mg/ m³ of soot, 50mg/ m³ of SO2 and 200mg/ m³ of NOx. 3.3.2.2 Impact Analysis of Water Environment The wastewater during operation period mainly comes from domestic sewage generated by passengers and workers, canteen dining wastewater and car wash wastewater, and the amount of wastewater generated is 106.9t/d. The domestic sewage of the project is treated by septic tanks, and the oily wastewater of the canteen is discharged into the regional sewage drainage pipe network through the grease trap and the car wash wastewater through the oil separation sedimentation tank, and discharged to Xining Municpal No.4 Sewage Treatment Plant for treatment. The wastewater of this project is simple in water quality and highly biodegradable. The water quality and water volume are all within the acceptable scope of the sewage treatment plant and will not cause a load impact for No. 4 Sewage Treatment Plant of Xining Municipality. 3.3.2.3 Impact Analysis of Accoustic Environment （1）Impact Analysis of Site Boundary Noise The main noise source during the operation period comes from impacts of the noise generated by the operation of the equipment required for the project and vehicle traffic noise upon the acoustic environment. According to the prediction results, the contribution value of equipment noise and vehicle traffic noise to each site boundary can meet the corresponding standards as required by the Standards of Environmental Noise Emission for Industrial Enterprises Boundary (GBGB12348-2008). Under the project, there is no vehicle and equipment running at night and the noise disappears, cuasing insignificant impact on the surrounding environment. （2）Impact Analysis of Accoustic Environment Protection Target The Qingtangxiao Town, located about 50m north of the project boundary, has become the project recent sensitive protection target. According to the calculation, during the operation period of the project, the recent sensitive protection target – the Qingtang Town can reach the Class II Standard of the Acoustic Environmental Quality Standard (GB3096-2008), that is, the 60 (dB) standard limit requirement in the daytime, the project operation noise will have a insignificant impact on the surrounding residents. 3.3.2.4 Environmental Impact Analysis of Solid Wastes During the operation period, solid wastes mainly come from living garbage and catering HAES -53- Qinghai Xining Urban Transport Project Environmental Management Plan water generated by passengers and staff, as well as sludge separated from the waste animal and vegetable oil and car wash wastewater. They shall be separately classified and disposed of. For the Chengxi Bus Terminal, vehicle maintenance is not carried out during the operation period. In event of vehicle problems, vehicles will be repaired outside of the bus terminal, with no resultant machine waste oil from repair. Domestic garbage is collected and transported to the municipal solid waste landfill for disposal. The waste animal and vegetable oil in the catering waste and grease traps should be disposed of by the kitchen waste treatment plant for harmless treatment. It is strictly forbidden to mix domestic garbage with canteen kitchen waste. The sludge separated by the car wash wastewater by the grease trap is hazardous waste (No. HW08). The construction unit shall set up a special temporary storage room for hazardous waste (10 m²). The sludge will be temporarily stored in the HW temporary storage area and handed over to the agency with the qualification of disposal of hazardous waste. All solid wastes during the operation period of the project can be properly disposed of. They will not be discharged, without a considerable impact on the surrounding environment. HAES -54- Qinghai Xining Urban Transport Project Environmental Management Plan Chapter 4 Impact Mitigation Measures Proper measures should be taken to enhance the positive impacts and mitigate the adverse impacts. The mitigation measures discussed in this section are focusing on the adverse impacts during the project design phase and implementation phase. The contractor should prepare detailed and site specific implementation plans for environmental protection measures prior to construction commencement. This will also be required in the bid of the contractor. The mitigation measures discussed in this section will be included in the tendering documents and listed in the Appendix B. The Contractor should make sure all mitigation measures are taken accordingly. The EMC will supervise the overall environmental performance and the contractor’s duties and obligations, and report to the PMO all findings so that necessary action can be taken promptly. 4.1 Design Phase 4.1.1 Social Environment The design of the project should be people oriented. The design should take consideration of existing conditions to reduce the acquisition of farm land, forest land and water area, and to avoid the sensitive building such as schools to reduce the needs of resettlement. The identification of the road alignment should also take consideration of the planned routes in the urban master planning. The selected road alignment should be in line with the relevant urban plans. (1) Follow relevant planning During the course of road alignment selection and alternatives selection, the Xining City Master Plan should be followed. The project design should take consideration of the existing conditions and aim at improving the quality and efficiency of urban transport infrastructure, at meeting the demand of industrial structure adjusting and future planning, and at realizing the “connecting and sharing” of urban transportation while properly handling the resettlement and ecological environment issues. The project should be able to serve the transportation need of regional economy and at the same time protect the ecological environment and landscape. (2) Reduce the land acquisition and resettlement need Construction projects inevitably will involve resettlement issues. The road alignment should avoid concentrated residential area, schools and important infrastructure facilities. The villages along the roads that are populous should be maintained and the road routes should be adjusted to minimize the need of resettlement. For important infrastructure facilities, the road alignment should be arranged to avoid mutual interference on operations of the road and the facilities. Complete the preparations prior to the commencement of construction works, including carefully investigating the project related information such as the road, power supply, telecommunications, coordinating with relevant entities to confirm the demolishing and relocating plans and preparing relevant emergency plan to ensure the regular social activities are not disturbed. HAES -55- Qinghai Xining Urban Transport Project Environmental Management Plan The land acquisition should be well arranged. Local government and affected people should be consulted and consensus should be reached on concerned issues such as the compensation method, the compensation standard and the implementation arrangement. For the land acquisition from the affected village and farmer, the land adjustment and labor placement should be conducted within the original village. Detailed plans should be prepared after consensus is reached to minimize the adverse impacts. The construction unit will be responsible for the land acquisition and resettlement and for providing compensation to affected people according to relevant national and local policies. The compensation should also take into consideration of the agriculture loss caused by the land acquisition. The cost is included in the engineering cost estimate instead of being listed as the environmental protection cost. 4.1.2 Land acquisition (1) Mitigation measures for land acquisition 1) One important principle to be followed in road alignment selection is to minimize the acquisition of farm land, green land and water areas; 2) The Design Institute should follow the Notice on the Enforcement of the Strictest Farm Land Protection Policy in Highway Development, Ministry of Transportation No. 164 (2004) in the design of road alignment, bridge and landscaping; 3) The land alignment design should take advantage of the relevant plans to use the land reserved for construction use; 4) In the road base design, the elevation, slope and earth work balance should be comprehensively considered to maximize the utilization of earth excavated; and 5) The design of temporary facilities such as the construction camp, the access road, and the mixing station should also be well arranged to minimize the temporary land acquisition, especially to avoid the acquisition of green land and water bodies. (2) Mitigation measures for affected people in land acquisition During the land acquisition, the national and provincial regulations on the compensation for land acquisition should be strictly followed to ensure that the interests of the affected people are protected. 4.1.3 Water Quality Protection In order to minimize the impact on the water bodies and to reduce the water pollution, special attention should be paid during the selection of river crossing method and the bridge structures to minimize the construction works in the water. The selected construction camp site should also be kept away from the water body. These measures can help reduce the water pollution caused in the construction of bridge foundation, or by the domestic wastewater from the camp. The project will use a bridge to cross the Huangshui River, and use a box culvert to cross the Yunguchuan River. According to the Xining Water Environment Function Zoning Plan, the Huangshui River is a Class III water body near the crossing location, and the Yunguchuan is a Class II water body near the crossing location. Both of them are drinking water source protection areas. Therefore, the wastewaters are not allowed to be discharged into the water bodies. HAES -56- Qinghai Xining Urban Transport Project Environmental Management Plan 4.2 Construction Phase The construction activities will cause different impacts on the environment along the roads, especially near the sensitive sites. The contractors are responsible for protecting the environment and mitigating the adverse impacts. The mitigation measures during construction phase will be incorporated into the bidding documents and contracts to ensure that effective environmental protection measures are implemented to protect the environment, and to protect the safety of workers and the local residents. 4.2.1Social Environment (1) Complete the preparations prior to the commencement of construction works, including carefully investigating the project related information such as the road, power supply, telecommunications, coordinating with relevant entities to confirm the demolishing and relocating plans and preparing relevant emergency plan to ensure the regular social activities are not disturbed. (2) Strengthen the propaganda on land acquisition and resettlement to allow the residents along the roads understand the significance of the project and to win their support to this project. Establish Information Board on the construction site with information on the project content, construction period, to seek the affected people’s support. (3) At the entrance of the construction site, an Information Board should be established with the contact information of contractors, supervision agencies and local environmental protection agencies so that the local residents can complain to relevant entities if their life are affected by the noise, air pollution, traffic congestion or other adverse impact or report to local authorities if they identify any non compliance activities of the contractor (4) If there are ancient trees or precious trees that have to be relocated, relevant regulations should be followed to apply for the permit and to arrange the relocation of the trees. During the construction, if cultural relics are found, the construction should be temporarily suspended promptly. The site should be protected while the culture heritage management authorities should be notified. (5) Prepare and implement the traffic management plan. Designate personnel to assist the traffic diversion during peak hours at busy roads near the construction site. (6) Minimize the impact on utilities services. If the impact is inevitable, the local residents should be notified and the interruption duration should be shorted as much as possible. (7) An effective complaints addressing mechanism should be established with the contractor and the client both designate personnel to handle the complaints. (8) The safety mitigation measures for the Xichang Avenue undercross at the Qinghai-to-Tibet Railway. Approval on the slow traffic management plan should be acquired prior to the construction of the undercross. During the construction phase, construction management and supervision should be strengthened to improve the construction quality. The construction should be scheduled properly to arrange the jack-in process during the intervals of the train operation. It is forbidden to conduct the jack-in process while there are trains on the rail. During the construction, the railway road base strengthening and protection should be improved to ensure the safe operation of the HAES -57- Qinghai Xining Urban Transport Project Environmental Management Plan railway. In order to prevent the hazard of falling gravels during construction phase and operation phase, it is suggested that the railway management agencies should install safety net on both side of the undercross. 4.2.2Ambient Air Pollution The below measures are recommended to mitigate the pollution to the ambient air. (1) Contain the construction site using boundary fence (hoarding). The boundary fence can be established by using corrugated board or polypropylene cloth to build a 2.5-3.0 meter fence to prevent flying dust from escaping. (2) Keep water spraying as necessary to quench the dust 1) During excavation, drilling and demolishing to maintain water content on the working surface 2) Frequently water the exposed dry soil surface on the construction site 3) Water the drying soil as necessary when conducting filling. 4) Use offsite mixing of the construction material. Conduct water spraying to quench the dust during compression. (3)Strengthen the storing site management 1) prepare surface compacting, regular watering and covering measures 2) Loose materials on the site should be contained. 3) The spoil soil that are no longer needed and the construction waste should be transported off site in a timely manner. 4) The construction materials that can cause flying dust should be placed together and covered. 5) The storage sites should be selected at least 200 meters away from the main residential area in the downwind direction. (4) Control the hazardous gas emission 1) No waste burning is allowed on site. The on-site canteen should use liquefied petroleum gas or electricity as heating source 2) The exhaust gas emission of the construction vehicles and machines should follow relevant national and local regulations and standards. 3) The construction material should be of good quality. The material containing hazardous substances should be checked to ensure compliance prior to being used. 4) Asphalt and coal tar type anti-corrosion and moisture-proof agent are not allowed to be used in the indoor decoration for civilian buildings. 5) The discharge of ammonia gas from the flame retardants or concrete admixtures used in the construction activities should comply with relevant emission standards. (5) The vehicles transporting earth or construction materials should not overload, and should either be covered by canopy or by other measures to avoid the spilling. The roads are cleaned and watered regularly to avoid resuspending of the dust. Each road construction contract should have a water vehicle. (6) Asphalt mixing machines with sealed container and equipped with dust quenching devices should be used. When the construction is completed, the site cleaning of the HAES -58- Qinghai Xining Urban Transport Project Environmental Management Plan mixing station should be conducted promptly. The waste should be recycled by the asphalt supplier or be sent to designated place by the local EPB. It is not allowed to be used as filling material. 4.2.3Water Environment The contractors should arrange the construction activities properly and ensure the construction activities will be kept within the red lines. At the same time, the contractor should make arrangement of wastewater discharge to avoid environmental pollution. The detailed measures are as below: (1) Domestic Wastewater Septic tanks will be installed on these sites so that the wastewater can be treated prior to being discharged for farm land use. (2) Construction wastewater 1) Oil separation and sedimentation tanks should be installed on construction sites. The construction wastewaters will be recycled after oil separation and sedimentation processes. They are especially forbidden to be discharged into the Huangshui River or the Yunguchuan River. The temporary toilets on the construction sites should have anti-leakage treatment. 2) Sedimentation tanks should be arranged near the mixing machines, the concrete pumps and cleansing station of vehicles. The wastewater will be reused after settling or used for dust quenching. 3) The fuels or chemicals should be stored in special storage room with anti-leakage treatment of the ground. The waste oil and chemical should be collected for treatment. Random discharge is forbidden. 4) The slurry from bridge construction should be treated. The recommended steps are (1) prepare the mud tank before drilling; (2) during the drilling, use the mud to carry the sand and rocks into the mud tank for sedimentation; (3) reuse the settled mud; (4) clean the mud tank regularly; and (5) the waste mud should be transported to designated location instead of being disposed randomly. (3) Management measures 1) The contractor should conduct water environment protection education at the construction sites and camps to allow the workers understand the importance of protecting water environment. At the sections near the Huangshui River and the Yunguchuan River, the contractor should strengthen the construction management and supervision, enforce regular mechanical inspection to avoid oil spill that might pollute the water bodies. 2) The construction schedule should be prepared properly. The bridge foundation and the box culvert constructions should be arranged during dry seasons. The sediments or dispose excavated should be removed promptly to reduce the impact on the water bodies and are not allowed to be discarded into the river or randomly stored. 3) The construction materials such as asphalt, oil and chemicals should not be stored near the water body and these storage places should be equipped with canvas as temporary cover. Other measures should be taken to avoid the clogging of trenches by earth or construction materials. 4) The wastes, no matter they are domestic waste, construction waste or maintenance HAES -59- Qinghai Xining Urban Transport Project Environmental Management Plan waste, should be sorted and recycled (usable material such as paper, wood, metal and glass materials). These waste that could not be recycled should be sent to sanitation utilities for treatment. 4.2.4Sound Environment The construction unit should take below measures to further mitigate the noise impacts. (1) Strengthen the noise monitoring. Implement noise reduction measures according to the Noise Limits of Construction Sites (GB12523-1990) and the Noise Measure Methods of Construction Site Boundary (GB/T12524-90). Conduct testing of the boundary noise and make sure it does not exceed the noise limit required by the national standards. (2) Try to use low noise machines if possible. Before the machines are mobilized, regular noise test should be conducted to avoid the machines with poor performance from entering the site. During construction activities, the machines should be well maintained to avoid the increase of noise level due to wearing. The vehicles are not allowed to use honking on the construction site. The material unloading should be conducted with caution. (3) According to the requirements of Emission standard for industrial enterprises noise at boundary, the boundary of the construction site should be reasonably identified, the entrances for construction and transportation vehicles should be arranged away from sensitive sites such as the residential area and schools. So also is the high-noise machine. Noise reduction measures might also need to be taken, such as containing. (4) Make reasonable arrangement for construction schedule and locations. When the construction site is near a sensitive site, the construction time should be adjusted based on actual conditions. High noise machines are not allowed to operate during night times (defined as from 22:00 PM to 6:00 AM). When continuous construction activities are needed, the contractor should contact the environmental management authorities in a timely manner and apply for the license for night time construction. At the same time, the contractor should issue public notice to inform the local resident and to seek their understanding and support. (5) Strengthen the vehicles arrangement and site management. Conduct civilized construction and noise supervision. The speed of bulldozer, excavator, and roller should be controlled within 8 km/hour on the construction site. The transportation of construction materials should be reasonably arranged. When the vehicles are passing by the villages or schools, they should reduce the speed and avoid honking. The construction management near schools and villages should be strengthened by preparing feasible construction plans. The supervision unit should be equipped with sufficient amount of noise detecting devices to monitor the noise level at the residential areas that are near the construction sites and to ensure that they are not impacted by the excessive noise level. (6) Make reasonable arrangement for construction schedule and locations. For the construction near sensitive sites, do not allow the operation of high-noise machines at night times. The high-noise work area should be arranged away from sensitive sites. If necessary, temporary sound block facilities should be established, or temporary hoardings should be established to substitute the sound block facility. For the earth works, multiple equipments should be arraigned to operate simultaneously to shorten the operating time. Avoid night time construction. When night time construction is necessary, adjust the light direction of HAES -60- Qinghai Xining Urban Transport Project Environmental Management Plan the lighting equipments to avoid disturbance to local residents, while fulfilling the lighting demand of the construction site. 4.2.5Solid Waste The solid wastes mainly include the spoils, the construction waste and the domestic waste from the workers. The below measures should be taken: (1) The solid wastes are not allowed to be disposed in the area of waters and riverbanks of the Yunguchuan River or Huangshui River. (2) The solid waste should be recycled as much as possible. The intact bricks and steel bars in the construction waste should be reclaimed. The other solid waste can be made into mortar for road construction after being sorted and smashed. The excavated soil should be used for filling by balancing the earthworks within the subproject or in the region and reduce the spoils. (3) As there are concentrated residential areas and the water bodies (including the Huangshui River and the Yunguchuan River) along the roads, the temporary storage and transport of solid waste should be reasonably arranged. The temporary storage sites should be covered by plastic or straw pad and surrounded by intercepting trench to avoid soil erosion. The sites should be distant from the Huangshui River. (4) The Xicheng Avenue crosses the Huangshui River as a bridge. During the construction of the bridge, the drilling mud should be discharged to the sedimentation tank to settle down the sand and rocks. Then the mud can be reused. The settled sand and rocks will be removed regularly. The waste mud that cannot be reused will be send to landfills. (5) The domestic waste during peak days should be collected, stored and transported to solid waste treatment facilities in a timely manner. The construction waste from demolishing should be sent to proposed Wuzhong Dagou Construction Waste Landfill. (6) Minimize the waste production during construction. When the construction is completed, the waste should be cleaned up completely. The solid waste produced during construction is linearly distributed along the roads, and it will impact the ecological environment directly if not properly stored or treated. Therefore construction management should be strengthened to remove the waste in a timely manner to mitigate or to prevent the solid waste impact. 4.2.6Ecological Environment 4.2.6.1 Terrestrial plants (1) Provide education and trainings on vegetation to construction workers. (2) Contain the construction site with hoardings to avoid the vegetation damage outside the site by the vehicles and machines. (3) Reserve the top soils from the farm lands for site restoration and landscaping use. (4) Restore the vegetation immediately after the construction. (5) Do not allow the use of herbicide and pesticide. (6) If key protection target is identified during construction, promptly report to local authorities for protection. HAES -61- Qinghai Xining Urban Transport Project Environmental Management Plan 4.2.6.2 Wildlife Protection (1) Improve the wildlife protection and no-hunting awareness of the construction worker. Do not hunt wildlife. (2) In order to reduce the disturbance of the wildlife from the construction noise, the construction method and schedule should be well prepared and reviewed to avoid the noise impact especially during the twilight period and the noon time. (3) The habitat should be restored after the project is completed to reduce the adverse impact on wildlife caused by the habitat damage. 4.2.6.3 Aquatic Life Protection The protection measures for aquatic life include: (1) Arrange bridge foundation construction during dry seasons and avoid rainy seasons. (2) The wastewater should not be allowed to be discharged into the Huangshui River or the Yunguchuan River. (3) After the construction is completed, the ecological environment should be restored. 4.2.7Soil Erosion There are three categories of soil erosion control measures including the engineering measures, biological planting measures and temporary measures. Prior to construction commencement, the construction unit should conduct a survey on the soil environment in the project area and prepare protection and restoration measures that are aimed at preventing the degradation of the soil and preventing soil pollution. The temporary measures including hoarding, drainage ditch and sedimentation tanks. The planting measures include vegetation restoration and landscaping. The engineering measures include top soil cut off and restoration, soil recovery and drainage facilities. The Table 4.2-1 summarizes the proposed soil erosion control measures. Table 4.2-1 Summary of Soil Erosion Control Measures Project area Type of Measures Control Measure Top soil cut off and recovery. At the both sides of the Engineering measures road base, use separated stormwater and wastewater Urban Roads area trenches and slope protection.

Top soil cut off and return, storm water pipeline, Engineering measures Yanxiaocun wastewater pipeline Interchange area Planting measures landscaping Temporary measures Temporary drainage trench, sedimentation tank Engineering measures Land rehabilitation Temporary soil Planting measures restore the farmland storage Bagged soil retaining, geotextile cover, soil drainage Temporary measures ditch According to the project scale, the terrain characteristics, and the construction methods, the HAES -62- Qinghai Xining Urban Transport Project Environmental Management Plan quantities of works for soil erosion control are estimated as below: Urban Roads (bridge construction area). The engineering measures include 500 m3 of top soil cutoff and restoration, 1.33 hm² of land leveling, 70 m of alloy gabion embankment. The planting measures include 1.33 hm² of landscaping. The temporary measures include cofferdam with bagged earth 180 m, canopy cover 0.095 hm², and 2 sets of mud tanks. Urban Roads (road construction area). The engineering measures include 47,800 m3 top soil cutoff and restoration, 2.37 hm² of embankment. The planting measures include 9.22 hm² of road side landscaping. The temporary measures include 14.29 km of temporary drainage ditches, 28 sets of sedimentation tanks on the road sides, and installing and demolishing of 1214 m temporary retaining wall at the foot of the filling slopes. Temporary soil storage sites. The engineering measures including 2.08 hm² post construction site cleanup. The planting measures including 2.08 hm² of farm land restoration. The temporary measures include the installation and demolishing of 620 m of fence enveloping made of bagged soil, 620 m of drainage ditch, and 2.08 hm² canopy cover. 4.2.8Mitigation measures of accumulated impacts The proposed roads under this Project will be constructed at the same time with the other three roads including the South Bypass Highway, the Chaidamu Road extension section, and the Wusixi Road (Huangshui River Section). In order to minimize the accumulated impacts on the local environment, the below measures are recommended: (1) Strengthen the coordination among different contractors in the arrangement of the traveling routes and schedule of construction vehicles to make sure the traffic on the existing roads near the construction sites are smooth and to reduce the number of traffic accidents. (2) Enhance the construction management near sensitive sites. Setup warning signs and speed limit signs. Conduct traffic diversion if necessary to ensure the safety of local residents. (3) The contractors should strengthen its management on transportation vehicles. The vehicles loaded with earth or other construction materials should either be covered by canopy or by other measures to avoid the spilling. The roads should be cleaned and watered regularly to avoid resuspending of the dust. (4) Make reasonable arrangements on the traveling routes of construction vehicles and stay away from sensitive sites. Make reasonable arrangements on the transportation schedule. When the vehicles are passing by residential areas or schools, they are required to reduce speed and banned of honking to minimize the noise impact. 4.3 Operation Phase 4.3.1Ambient Air The construction unit or management unit of the Project should enhance the enforcement of HAES -63- Qinghai Xining Urban Transport Project Environmental Management Plan the policies or regulations in the whole city, while taking relevant measures to control the vehicle exhaust gas emission on the roads in this Project. (1) Request the vehicles with new registrations to follow the strict emission standards. (2) Strengthen the maintenance of vehicles and prevent the vehicles with excessive emission from being used. (3) Strengthening the traffic management to maintain smooth traffic. (4) Promote the clean fuel such as the natural gas. (5) Avoid developing new sensitive sites along the roads (6) Enhance the maintenance of the road side landscaping. 4.3.2Water Environment The sources of water environment pollution are mainly the oil-containing wastewater from vehicle vehicle maintenance and the gas station cleansing wastewater at the Yanxiaocun Interchange, the domestic wastewater from the working staff and the passengers, and the road surface runoff. (1) Road According to the engineering design, the roads will have associated drainage system with separate stormwater and wastewater collection system. The road sections are within the service area of the No. 4 WWTP. The wastewater along the roads will be discharged into the city sewer and then be transported to the No. 4 WWTP for further treatment. After the project is completed, the storm water will be collected in the storm water pipeline and be discharged to the Huangshui River and the Yunguchuan River. Normally the road surface runoff carry only low amount of pollutants and will not cause significant impact to the water environment. The bridges crossing the Huangshui River and the Yunguchuan River will have bridge surface runoff collection system and accident tanks on both end of the river to collect the initial rain water or post-accident runoffs. There will be warning signs with warnings such as “cautions” or “reduce the speed” at the bridges. The bridges will also have crash barrier to prevent the vehicles from falling into the river. During the operation phase, the local authorities will regular conduct maintenance of the drainage and sewer system. 4.3.3 Sound Environment The highway traffic noise control measures mainly include the road alignment adjustment, sound block, sound insulation window, and noise-reducing landscaping, etc. The proposed roads under this Project are mainly trunk roads (the Xicheng Avenue, the Wusixi Road Extension Section, and the No. 5 Road) and branch roads (the Guihua 1 Road and the Guihua 2 Road). According to the noise projection results for reference years (1st, 7th and 15th years after operation), the road traffic noise and the noise level at some sensitive sites will exceed the limits. In order to reduce the noise impact and improve the sound environmental quality, below measures will be taken: (1) For Roads 1) In the empty area at both sides of the road, greenbelts should be built to reduce the noise impact and ecological impact. 2) During operation, the road maintenance should be strengthened to maintain the road HAES -64- Qinghai Xining Urban Transport Project Environmental Management Plan smoothness. 3) The motorized vehicle management should be strengthened to ensure the vehicles using the road are in good conditions 4) Honking should be banned along the roads. (2) For Sensitive Sites According to the Xining Urban Master Plan (2001-2020), the city will expand towards the east and the south directions in the short term (by 2005) and in the mid-term (by 2010), towards the west and the north directions in the long term (by 2020). While according to the Xining Urban Space Development Plan (2030), the city will develop the south part of the Xichuan New Urban Area in the mid-term (2016-2020) and the north side in the long term (2020-2030). The urban roads under this Project are within the planned Xichuan New Urban Area. The planed land use along the roads is mainly for residential use. It will be a key area of future development of the city. According to the noise prediction results, in the short term (2018) the noise levels at the sensitive sites will be all below the limits. And in the mid-term (2024), except for the night time noises at the Taobei Village along the Wusixi Road and the Wangjiazhai Road along the Xicheng Avenue will exceeds the limits by a range of 1.1-5.1 dB(A), other noise levels will all be below the limits. With consideration that the city is expanding at a very fast pace along the roads and the Taobei Village and the Wangjiazhai Village are very likely to be relocated, this Report will not propose any engineering measures to reduce the noise level for the mid-term. However, during the roads operation, the landscaping, the traffic management and the road maintenance should be strengthened. In addition, the monitoring frequency should be increased. If significant adverse impacts are identified, timely remedial measures should be taken, such as the resettlement or the changing of the building functions.

Strengthen the management and maintenance of motorized vehicle and prevent vehicles with poor condition from using the road, especially the heavy duty vehicles which have the most severe noise problems. 3) Setup speed limit sign or traffic lights at intersections or near the concentrated residential areas so that the traffic will be moving at constant speed and do not use horns. 4) Strengthen the monitoring of traffic noise. If non-compliance is identified, remedial measures need to be taken in a timely manner to reduce the amount of incidents of traffic noise disturbance. (4)Requirements on the road side development The noise protection distances for planned development are determined based on the predicted noise levels during the midterm operation phase. The results are shown in the Table 4.3-3. Table 4.3-3 Noise protection distances during the mid-term operation, m Class 4a standard Class 2 standard Road 2018 2024 2032 2018 2024 2032 name Day Night Day Night Day Night Day Night Day Night Day Night time time time time time time time time time time time time Wusixi / 34 / 51 / 59 42 57 51 120 53 144 Road Xicheng / / / 41 / 66 / 34 40 94 60 167 Avenue No. 5 / / / 25 / 37 / 23 25 39 35 69 Road In the case that no noise control measures are taken, there should not be any noise sensitive buildings such as new schools, hospitals, nursing homes or residential areas to be built in the area for which class II standard is applicable. It is suggested that the planning department should avoid planning noise sensitive sites such as concentrated residential area, hospitals and schools within the noise protection distance. If such sensitive buildings are necessary, the construction unit should adopt measures such as the building sound insulation or others so that the indoor environment quality can meet relevant functional requirement. 4.3.4 Solid Waste During the operation phase the solid waste on the roads is mainly from the domestic waste produced by the pedestrian. It will be handled by the municipal solid waste management system. The solid waste will be sorted and collected using the garbage bins placed on both sides of the roads. The solid wastes that cannot be recycled will be sent to the Liujiagou HAES -66- Qinghai Xining Urban Transport Project Environmental Management Plan sanitary landfill or other designated locations for disposal. 4.4 Accident risks prevention 4.4.1Traffic accidents (1) Strengthen the transportation management along the road; Setup necessary signs with information such as the speed limit and the road shape; randomly conduct traffic safety checkup to reduce the amount of traffic accidents. (2) Prevention of risks in hazardous chemical transportation The roads in this Project are mainly urban trunk roads that do not allow hazardous chemical transportation. The transportation of such chemicals will take the route of the branch roads at the south end of the city. Therefore, there is little or no risk of water pollution caused by traffic accidents with vehicles loaded with poisonous or hazardous substances. However, these regulations should be strictly followed in actual situation by strengthening the management and monitoring. In rare occasions when the hazardous chemicals must be transported on these roads, report to the local police department and environmental protection department, and prepare a hazardous substances risk management plan in advance. Follow the time and road sections designated by the police department for the hazardous substance transportation. Implement a traffic control by the police department if necessary. The vehicles used in the transportation should strictly follow the Rules of Regulations on Safety Management of Hazardous Chemicals. (3) Prevention of traffic accidents risks on bridges The proposed roads cross the Huangshui River in the form of a bridge and cross the Yunguchuan in the form of a box culvert. According to the Xining city water environment function zoning, at the locations of the crossings, the Huangshui River is a category III water body and the Yunguchuan is a category II water body. Both of them are drinking water source protection areas. The notice on the strengthening the EIA of highway planning and development jointly issued by the legacy national environmental protection agency, the national development and reform commission, and the ministry of transportation (No. 184, 2007) states: In highway construction particular attention should be paid to the protection of drinking water sources. The design of the route should be avoid drinking water source protection areas. In order to prevent the environmental risks brought about by the transport of hazardous chemicals, for the bridges crossing the class II drinking water protected areas, the secondary protected areas, and class II (and above) water bodies, when the safety and technical feasibility is ensured, there should be a surface runoff collection system on the bridge and sedimentation tanks on both ends of the bridge to treat the runoff collected after a pollution incident occurs, to ensure the safety of drinking water. As the transportation of hazardous chemical is not allowed on the proposed roads, there is little or no risk of water pollution caused by traffic accidents with vehicles loaded with poisonous or hazardous substances. However there is still a possibility of water pollution if there is a traffic accident such as a collision, or a rollover. The risks of traffic accidents are mainly at the river crossing locations. During the operation phase, the prevention measures for water pollutions include: HAES -67- Qinghai Xining Urban Transport Project Environmental Management Plan 1) Build the runoff collection system and sedimentation tanks. If a fire or a hazardous chemical spill occurs, these facilities can be used to collect and store the cleansing waste water or fire fighting waste water. The effluent of the sedimentation tank will enter the road side ditches. The ditches should not be connected with sensitive rivers. This measure can help effectively prevent the hazardous chemical from impacting the water quality in the river. 2) Select the pipeline material that is able to meet the requirements of the strength and stiffness, has a long service life, and is resistant to corrosion caused by acid or alkali so that it can be used for hazardous chemical collection. 3) Improve the containment capacity to a level sufficient enough to prevent the accident vehicles from falling into the river. 4) Set up warning signs with contents such as “River area, drive with caution”, “Bridge ahead, do not pass” or information about speed limit. Emergency phone number should be clearly listed. 5) The traffic accidents on the Huangshui Bridge of Xicheng Avenue should be incorporated into the municipal emergency plan. An emergency plan should be prepared with emergency aid equipments and devices provided. An environmental risk emergency commanding center and a field team should be established. When an accident occurs, it should be promptly reported to the police department, and informed of to the highway management, fire protection and environmental protection departments so that the emergency response measures can be taken to prevent the escalation of pollution and hazard. 4.2 Mitigation Measures for Environmental Impacts of the MR Project 4.2.1 Requirements of Environment Protection during the Design Period According to characteristics regarding social environment, natural environment and regional planning along the proposed project roads, it is necessary to implement the concepts of environmental awareness and project design of "high commitment, full details, cost-effectiveness and effective management” in the whole process of project engineering design. Adequate consideration is given to the requirements with respect to environmental protection and urban landscape. It is important to take ecological greening as the background, to attach high importance to ecological protection, and to promote the sustainable development of social economy. (1) Landscape Design: For urban road greening, it is necessary to initially select camphora, platycladus, cypress, privet, boxwood and other evergreen species. Plant landscaping can improve ecological environment of highways, playing a role in cooling air temperature, increasing air humidity, improving soil vacuuming, etc. on the other hand, it is less affected by landform and topography, but it can improve them and beautify some unattractive artificial structures, thus enabling rigid road facilities full of life. The green space of highways is linear. In the selection of composition elements, there should be an assurance of a unified sense of coordination of green spaces along the roads. HAES -68- Qinghai Xining Urban Transport Project Environmental Management Plan Each road section should have its own theme or characteristic to enrich its road landscape. It is also necessary to plant trees, flowers or native species of rich local characteristics, forming a unique local feature. (2) Before the physical construction, all preparatory work should be done adequately to conduct a detailed investigation and a better understanding of various pipelines on the roads and in the underground roads with respect to regional roads, power supply, communications, water supply and drainage under the project. Emergency responsive preparation shall be done adequately to ensure that the cut-off of pipes and pipelines when construction is under way will not affect or destroy municipal facilities involving water supply, power supply, communications and the like. (3) According to relevant requirements of the "Design Norms for Outdoor Drainage" (GB50014-2006 (2014 version)) and those of road surface runoff in the sponge city planning, it is proposed that measures for rainwater collection system of low impact development of (LID) be adopted. The key measures are as follows: Road rainwater collection system is an important component of rainwater collection system of low impact development (LID). LID rainwater collection methods mainly include water seepage paving, concave green land, ecological grass ditch and stranded ponds. Through these rainwater collection methods, the urban runoff coefficient and the peak flow of rainwater pipe network are reduced; and the pollutants contained in the rainwater are greatly reduced, hence the pollution of rainwater to water system. ① Pedestrian sidewalks shall be provided with permeable pavements, which can effectively reduce road runoff amount; ② Tree ponds shall be built with shallow ditches of grass or grate with mangrove barks, slightly lower than pedestrian sidewalks, making the sidewalks flow into the planting ponds. Through the combination of underground infiltration, drainage pipes and overflow pipes, the collection and management of road rainwater can be realized; ③ Non-motorized roadways shall be provided with stanchion in the form of open holes to ensure that excessive road rainwater can be collected and discharged into green lands smoothly, After being infiltrated into the sub-grade drainage system, the rainwater can be finally discharged into rainwater wells; ④ The rainwater on the pedestrian sidewalks and bicycle lanes drains into concave green land plots along the roads. Their effective volume is used to store the rainwater. The rainwater is infiltrated into the gravel layer through the infiltration pipe and collected into the storm water pipeline system through perforated pipes. When it rains heavily, up to a certain level, the rainwater overflows to the concave intake and runs into the storm water pipeline. The rainwater on the road first enters into the concave green space, and a large amount of pollutants mixed with the rainwater will be deposited into the concave green space. On the one hand, the pollutants are degraded and absorbed by plants and microorganisms in the concave green space, and on the other hand, clearing up shall be done manually on regular basis; HAES -69- Qinghai Xining Urban Transport Project Environmental Management Plan ⑤ rainwater pollutants collected by water seepage pavement and sinking green space will be greatly reduced. The rainwater can be collected into the rainwater storage ponds (ponds), and be reused by using pump pressure. 4.2.2 Related Requirements of Bidding & Tendering for Physical Construction （1）Bidding Phase ① The preparation of bidding documents should reflect the EIA results of the project, clearly setting environmental protection targets for all tenders and clarifying responsibilities and obligations of project contractors with respect to ecological environment protection, soil and water & soil conservation, population health and environmental improvement. ② It is important to propose concrete environmental protection requirements for construction organization plans of all tenders, specifically, preparing an implementation plan for environmental protection, and providing corresponding personnel with environmental background and environmental protection facilities. ③ It is also necessary to standardize the bid preparation and review to ensure that project contractors can obtain reasonable profits, enabling them to implement environmental protection plans. （2）Tendering Phase ① Tendering documents shall respond to requirements of bid invitation documents with respect to environmental protection issues, formulating the construction organization plans and implementation measures in line with the requirements of environmental protection, and providing corresponding environmental protection management personnel and corresponding facilities. ② The price quotation of tendering documents should be based on the investment cost budget required for rationally formulating and implementing environmental protection management and countermeasures according to concrete environment protection requirements of all bidders. ③ The project contractor shall be highly committed to its responsibility and obligation of environmental protection, and shall not be allowed to undertake repeated subcontracting and repeated charging commission fees, but voluntarily supervised by implementing agencies and local environmental protection units. （3）Bid Evaluation Phase ① There needs to establish a team of highly competent bid evaluation experts, and attention has to be paid to the introduction of senior environmental experts to participate in bid evaluations. ② It is necessary to carefully review the contents of construction organization plans concerning environmental protection and constructional civilization, and in particular, to strengthen examination of environmental protection safeguards and to prevent construction contractors who intend to win award illegally and arbitrarily lower environmental protection input from becoming potential award-winners. HAES -70- Qinghai Xining Urban Transport Project Environmental Management Plan 4.2.3 Measures for Prevention & Control of Pollution during the Construction 4.2.3.1 Measures for Prevention & Control of Atmospheric Environment Pollution According to the Management Methods on Civilized Construction for Construction Projects in Xining Municipality, the Regulations on the Prevention and Control of Atmospheric Pollution in Xining Municipality and the Guidelines for Dust Control on Construction Sites in Xining Municipality (Reference No. Ningqi Zhiban [2013] 5) as well as the Management Methods for Urban Building Spoil Transpiration in Qinghai, five “100%s” shall be adequately implemented, specifically, 100% of building construction sites shall be enclosed; 100% of road pavement on the construction sites shall be hardened; 100% of earthwork shall be fully covered while not in use; 100% of demolition works shall be given water sprinkling; and 100% of vehicles going out of construction sites shall have wheels rinsed. In order to do a fine job in addressing the issue of prevention and control of flying dust at construction sites and in the road transport, the following measures are developed to reduce the impact of the project construction on the environment. They are as follows: （1）Demolition Works ① For the proposed project roads, the scenario of physical construction by road section, halfway construction and halfway travel shall be adopted. Before original hardened pavement layers are removed, both sides of the road sections apart from their entrances and exits should be enclosed, with continuous enclosure settings that are not interrupted or having gaps. their enclosure materials should be made of hard plate color steel, with brick foundation reinforcement. Their enclosure shall have a height of not less than 2.5 meters. ② Entrances and exits of demolition works sites should be hardened with concrete, with vehicle washing facilities. It is necessary to arrange cleaning staff to do washing work on the vehicles going out of the construction sites. The demolition sites shall be provided with drainage ditches and sedimentation tanks to ensure that drainage is unobstructed, preventing wastewater from flowing outside of the demolition work sites. ③ When wind speed easily generates flying dust at the above level 4, the demolition unit must temporarily stop its dismantling work and take effective measures such as wetting to the dismantling site to prevent the flying dust from scattering. ① Demolished construction wastes should be cleared up and shipped away in a timely manner. If they cannot be timely transported and removed for special reasons and have to be piled up on the demolition sites temporarily, the matter should be reported in writing to the authorities in charge of physical construction under the jurisdiction of the construction area for approval. The construction garbage shall be covered, with a stacking height of lower than the height of the fencing wall. For those units that have completed the demolition, but not started construction within 15 days should take measures such as covering and watering to suppressing flying dust. If one construction unit fails to obtain a construction permit for over six months, dustproof measures shall be taken on the exposed ground of the demolished site. ⑤ Transport vehicles going in and out of the demolition sites should be kept clean, without carrying mud on the road and exceeding their rated capacity. Moreover, airtight transport shall be carried out at low speed so as to ensure that there will b no dust pollution during transport. HAES -71- Qinghai Xining Urban Transport Project Environmental Management Plan (2) Flying Dust from Construction Sites ① Before the commencement of road construction, the construction unit shall set a 2.5m-high hard enclosure outside the half-width range of the construction road as per standards to carry out the entire enclosure on the construction site and maintain the enclosure in the construction process; ② At the entrance and exit of the construction site, the person in charge of construction site, environmental supervisor, dust pollution control measures and whistleblower telephone number should be publicized; ③ The earthwork temporarily stored in the ditch excavation shall be given covering measures, and the excess earthwork shall be promptly cleared up and transported to designated building garbage landfill sites after constructional backfilling; ④ When Level IV or more wind blows or the heavily windy weather occurs, earthwork shall be stopped and at the same time covered in the operating area; ② Water sprinkling shall be carried out 4-5 times a day at the construction site on an irregular basis; ⑥ Exposed surface areas shall be provided with ground compaction, covering or temporary greening and other dust-proof treatment measures. Construction wastes and spoils must be timely cleared up. For those that cannot be treated temporary, they shall be treated with covering measures. （3）Flying Dust from Transport Vehicles ① Vehicle-washing platform shall be set at the entrance and exit of the construction site, and 100% of the vehicle bodies on the construction site are rinsed; ② Construction site entrances and exits shall given full hardening of pavement; ③ Vehicles transporting construction spoil vehicles should be of specific operating vehicle type or in airtight, anti-spill, anti-flying condition, and up to standard in terms of motor vehicle noise and exhaust pollution control. ④ Construction sites shall be cleaned from time to time so as to enable construction roads and the roads within 100 meter of their entrances and exits not to retain soil and construction wastes. (4) Temporary Construction Site ① Temporary construction sites shall achieve full hardening; ② 100% of temporarily unused building materials (like cement, sand, etc.) shall be given shielding or covering; ③ Construction sites shall be cleaned from time to time and be given water sprinkling to suppress flying dust. ④ Road drainage pipes and common utility tunnels are constructed by road sections. Excavated earthwork is temporarily piled on one side of pipeline ditch but it should be given covering measures. After construction backfilling, excessive earthwork is timely cleared up and shipped to the designated construction waste landfill. HAES -72- Qinghai Xining Urban Transport Project Environmental Management Plan After taking the above measures, it is possible to greatly reduce the impact of construction dust on the surrounding environment. 4.2.3.2 Water Environment Protection Measures During the construction period, the construction unit should strictly organize and construct within the prescribed scope so as to minimize the occupied water area and make civilized construction. At the same time, the construction unit should organize the design of wastewater discharge and strictly prohibit random discharge and pollution to pollute the environment. Specific measures are as follows: (1) Measures for Domestic Sewage Treatment The project is located in the urban area of the Xining City. According to the characteristics of social environment along the project, the drainage status along the roads is in the charge of Xining No. 1 Sewage Treatment Plant. The construction sites shall be provided with septic tanks and drainage pipelines for constructional purpose, which can be linked with the municipal sewage pipeline system. The living sewage after entering the municipal sewage pipeline system through the septic tanks can be discharges into Xining No.1 Sewage Treatment Plant in Xining for treatment. (2) Measures for Construction Wastewater Treatment Construction wastewater largely consists of mechanical and vehicular wastewaters. The EIA requires that temporary sedimentation tanks, grease traps be built in temporary working sites. after entering the temporary sedimentation tanks through grease separation, the equipment flushing water will be treated there. After more than 12 hours of sedimentation treatment, the main pollutant SS in the wastewater can be reduced to less than 200 mg/L, which can be recycled. For example, it can be used for equipment flushing as well as water sprinkling for dust suppression. It is noted that discharging the wastewater into the Nanchuan River and the Huangshui River shall be banned, that is, the construction wastewater discharge shall be strictly controlled so as to avoid local water pollution problems. 4.2.3.3 Measures for Accoustic Environment Protection The forecast results show that the noise generated during the construction of the project partially exceeds the requirements of the Emission Criteria for Environmental Noise of Boundaries of Building Construction Sites. Although the construction operation noise is unavoidable, in order to reduce the noise impact on the surrounding environment, the implementing and construction units shall standardize constructional activities as specified in the "Regulations on Prevention & Control of Environmental Noise Pollution of the People's Republic of China". Prior to the startup of the project construction, the construction unit shall declare project name, construction site and period, possible environmental noise value and the noise pollution prevention and control measures taken to the project area and corresponding prevention & control of environmental protection measures to be taken, to the project location district and its authorities of environment protection. In addition, it is recommended that the construction unit, appropriate measures be taken to reduce the noise pollution generated from the following aspects: HAES -73- Qinghai Xining Urban Transport Project Environmental Management Plan （1）Noise of Road Construction ① Low-noise equipment and processes shall be selected in line with national criteria to fundamentally reduce source intensity. It is necessary to strengthen inspection and maintenance of machinery and equipment. The overall equipment should be kept stable to maintain good contact with the ground. With good sources, the construction unit can use vibration-reducing machinery base to reduce noise pollution; ② In terms of optimization of construction layout, high-noise construction sites shall stay as far as possible away from sensitive points. It is wise not to arrange a number of power machinery and equipment at the same location to avoid extremely high local noise so as to reduce noise from the sound source; ③ It is important to strengthen operational noise control by reasonably arranging construction timing. According to the “Management Methods for Civilized Construction for Construction Projects in Xining Municipality", in the concentrated areas of noise-sensitive urban buildings, it is prohibited to undertake night operations leading to environmental noise pollution". Given that a number of acoustic environment sensitive points are densely distributed along the urban roads, the project construction shall be arranged in the daytime period (8:00 am -22:00 pm) instead of nigh period (22:00 pm -6: 00 am); ④ The project shall be of half-way construction by road section, with enclosed fences in the construction road sections. The enclosed enclosure shall be made of hard-quality materials such as color steel plates, with a height of less than 2.5 meters. The enclosure helps to reduce the impact of construction on the surrounding sensitive targets of acoustic environment protection. (2) Noise of Temporary Integrated Construction Sites ① Temporary construction sites should be kept away from sensitive areas such as residential areas, hospitals and schools; ② For construction machinery in the integrated construction sites, simultaneous construction of high-noise equipment shall be avoided as far as possible; ③ For fixed equipment, it is necessary to set up simple enclosure to make sure that it can be closed or semi-enclosed place while working. (3) Noise of Transport Vehicles ① Vehicles transporting construction muck or slag shall be of special operation type with airtight, anti-leakage and anti-flying conditions and shall comply with the standards for motor vehicle noise and exhaust gas pollution control. ② The existing roads in the project area will be used for transporting construction materials during the project construction period. Care should be taken to arrange the transportation timing of construction materials reasonably. In the vicinity of the road sections with urban residential compounds, it is required that vehicle travel be slowed down, with no whistling or horning. (4) Other Measures for Prevention & Control of Noise ① Steel pipes, models and other structural parts shall be handled carefully and properly, HAES -74- Qinghai Xining Urban Transport Project Environmental Management Plan with no throwing; ② Commercial concrete shall be used so as to avoid the generation of on-site production noise. ③ It is necessary to strengthen construction management of intersecting road sections by formulating detailed construction management plans. ④ The supervising unit shall do a good job of noise supervision during the construction period, by improving construction management. A certain number of noise measuring instruments shall be equipped with to monitor residential compounds near construction sites to ensure that the they will not be affected by over-standard noise pollution. With the above measures taken, the noise in the project construction period will be effectively controlled. The adverse impacts of construction noise on the surrounding environment is temporary and short-term. With the completion of the project construction, the construction noise will disappear. 4.2.3.4 Measures for Solid Wastes Solid wastes in the project construction period mainly consist of abandoned earthwork and living garbage of construction workers. The proposed environmental protection measures for solid wastes include: (1) Abandoned earthwork mainly includes removed original pavement slag, residual earthwork after ditch excavation and rational utilization, and bridge foundation drilling slag. The abandoned spoils or slag under the MR project is proposed to be shipped uniformly to the commercial slag disposal site of the Zhengjuan Company at the Najia Mountain for disposal. (2) Domestic rubbish shall be regularly handed over to the sanitation unit for disposal after being classified and collected. (3) For the facilities, equipment and sites for collecting, storing and transporting solid wastes management and maintenance shall be strengthened so as to ensure their normal operation and use. It is not allowed to discard and scatter solid wastes along the way in the course of transportation. 4.2.3.5 Ecological Protection Measures (1) The flowers and trees along the urban roads need doing a good job of transplanting protection. It is necessary that they not be destroyed for new afforestation, but be removed for temporary transplanting purpose. According to the project design, it is better to carry out make-up replanting. In the construction process, care should be taken to protect vegetation like trees and green land in adjacent areas. (2) During the construction period, the road construction should be carried out within the red line as far as possible. The material stacking and spoil storage sites shall be set up within the permanent land occupation area, with no spoils or materials piled up occupying nearby areas. (3) During the construction period, for large amounts of trash accumulation resulting from the breaking up of road pavement, there should be an orderly section by section construction, with proper enclosure. Meanwhile, the resultant spoils should be cleared up HAES -75- Qinghai Xining Urban Transport Project Environmental Management Plan and transported to the designated commercial spoil disposal site in a timely manner to avoid forming a phenomenon of disorderly and unattractive landscape. (4) It is necessary to do a good job in the rational allocation of earthwork for excavation and backfilling. Protective measures shall be taken for temporary storage of abandoned spoils. There is a need to prevent excavation and filling of earthwork during rainfall to prevent rainwater flushing from causing soil erosion, water body pollution and blockage of drainage pipes. Abandoned soil surface should be rammed, with bagging block for temporary soil storage. Meanwhile, they should be covered by ecotextile materials. Drainage ditches are set around the temporary spoil points. Rainwater enters the grit-sinking ground through the drainage ditches. The rainwater can be discharged into the municipal pipeline system after being grit-grounded. (5) Under the premise of meeting the requirements of project construction, it is wise to save land occupation as much as possible and make reasonable arrangements for construction progress. After the project is completed, the construction sites should be timely cleared up, leaving the occupied sites empty and restoring the original roads and greening space. 4.2.4 Measures for Prevention & Control of Pollution during the Operation 4.2.4.1 Measures for Prevention & Control of Atmospheric Environment Pollution The EIA report recommends adopting the following measures to further reduce the impact of waste gases on the surrounding environment during the project period. (1) Prohibiting Traveling of Vehicles with Over-standard Emission of Exhaust Pollutants In order to reduce exhaust pollutants emission of motor vehicles, urban traffic control authorities shall carry out the system of exhaust emission of vehicles to prohibit the travel of vehicles exceeding the emission limit. All vehicles with over-standard emission of exhaust gases shall be banned on the urban roads. (2) Strengthening Inspection and Maintenance of Motor Vehicles Exhaust pollutants emission of motor vehicles is highly correlated with sound operation of vehicle engines. Over-standard exhaust emission of the motor vehicles is a result of such factors as low level of maintenance and technical deterioration of engines. When the motor vehicles use unleaded and installing exhaust purifiers, it becomes even more important to carry out inspection and maintenance. Therefore, it is important to strengthen vehicular inspection and maintenance so that they can be kept in good condition more often so as to reduce the emission of exhaust pollutants. (3) Keeping the Roads Clean, Timely Watering and Road Dust Reduction As road dust comes from dust particles fallen onto the road pavement, reducing these dust particles means reducing the source intensity of pollution. (4) Taking Advantage of Vegetation for Air Purification Experiments show that broad-leaved arbors on both sides of the roads have certain dust-proof and pollutant-purifying effects. The construction unit should carry out afforestation on both sides of the roads according to the provisions of the "Regulations on HAES -76- Qinghai Xining Urban Transport Project Environmental Management Plan Urban Afforestation Management in Xining Municipality" to make full use of vegetation for ambient air purification. (5) Intensifying Efforts of Environmental Management. Road Environment Authorities shall set up an environmental management agency that can entrust the EP department to conduct regular environmental air monitoring at the designated monitoring points as specified in the EIA. 4.2.4.2 Measures for Prevention & Control of Accoustic Environmental Impacts During the project operation, a series of measures must be taken to ensure a good acoustic environment on both sides of the urban roads, including measures for engineering control itself, planning and planned control requirements for the construction along the routes, self control measures at environmentally sensitive sites at a later stage, etc. (1) Self Engineering Control Measures 1) Road maintenance should be strengthened to ensure the leveling of road pavement, so that the increase of traffic noise caused by vehicle jolting and bumping due to poor road conditions can be avoided; 2) Motor vehicles on the roads are ensured to be in good operation condition. The management and maintenance of motor vehicles should be strengthened to ban unqualified vehicles from getting on the roads. In particular, heavy-duty trucks on the roads have the most serious noise pollution. It is suggested to implement the management of limited trips of yellow-labeled vehicles. 3) Speed limit signs and intersectional traffic lights will be set up for nearby road sections near the sensitive points such as horizontal crossings, residential areas, schools and hospitals along the routes to ensure sound vehicle driving, with no horning. 4) Afforestation should be carried out along the roads. For tree species, it is better to select evergreen tree species with relatively large canopy and leaf area. And low shrubs should be planted near the tree species to effectively reduce traffic noise. According to related researches, greening for noise reduction mainly involves the effects of reflection and absorption on sound waves. Vegetation itself is a kind of porous material that has a certain sound absorption function, which can reduce the energy of sound waves, hence the role of noise reduction. The project can construct artificial topographical spots for noise reduction under available favorable conditions. Planting tree species shall adopt the dual layer structure of arbors, shrubs and grasses so as to achieve good effects of sound insulation and noise reduction. (2) Strengthening Rational Planning and Building Layout along the Road Routes Based on the forecast results, in the absence of building obstructions, noise up-to-standard distances of categories 4a, 2 and 1 areas in the short-term, intermediate and long-term project periods are shown in Table 5.2-17. HAES -77- Qinghai Xining Urban Transport Project Environmental Management Plan According to the above road noise up-to-standard distance, the EIA puts forward the corresponding requirements regarding noise protection distance. Without noise prevention and control measures, within the above range of up-to-standard distances corresponding to the criteria of Category 4a, Category 2 and Category 1, it is not appropriate to newly build schools, hospitals, governmental institutions, nursing homes and residential compounds and other sensitive buildings. In the meanwhile, reasonable planning and building layout along the roads should be strengthened, and the construction planning authorities should reasonably plan the areas on both sides so as to avoid planning concentrated sensitive points such as residential areas, hospitals and schools within the noise up-to-standard distances. When the new construction of above sensitive points with the noise up-to-standard distances is necessary, it is ordered that the construction unit take sound building insulation or other noise reduction measures according to the national laws and regulations on environmental noise in order to make indoor environment meet functional requirements. In the meantime, for buildings of no noise sensitive types such as shops, production and office buildings, commercial buildings, the noise up-to-standard distances of back-row buildings will be shortened due to the blockage effect of these buildings. (3) Scenario of Noise Prevention & Control at Sensitive Points According to Table 5.2-18 (Analysis of Forecast Results of Environmental Noise at Sensitive Points), in using SMA asphalt concrete low-noise road pavement, during the immediate (2019), midterm (2025) and long-term (2033) periods of project operation, daytime noise at all sensitive points can meet the requirements of criteria as specified in the "Acoustic Environmental Quality Criteria" (GB3096-2008). At most sensitive points along the urban roads, noise at night can meet the corresponding standard requirements of the "Acoustic Environmental Quality Criteria" (GB3096-2008). A limited number of near-road row-1 sensitive points along the urban roads are slightly over standard at night. According to the statistics, in the immediate period of project operation (2019), they are as follows: near-Qiyi-Rd row-1 building (floor 1) of Qinghai Public Health Vocational Technology College (over-standard 2.2 dB at night); in the midterm period of project operation (2025), near-Qiyi-Rd row-1 building (floor 1) of Qinghai Public Health Vocational Technology College (over-standard 2.2 dB at night), the building (floors 1,5,7) of the Qinghai MCH Hospital (over-standard 0.5-0.8 dB (A) at night); in the long-term period of project operation (2033), near-Qiyi-Rd row-1 building (floor 1) of Qinghai Public Health Vocational Technology College (over-standard 2.2 dB at night), the building (floors 1,5,7) of the Qinghai MCH Hospital (over-standard 1.5-2.1 dB (A) at night), near-road row-1 (floors 2, 4) of Ganxiusuo RC (over-standard 0.8-0.9 dB(A) at night), near-Bayi Rd row-1 building (floor 3) of Shen Meitan Wuce RC (over-standard 0.4 dB(A) at night), the near-Changjiang-Rd building (floors 4, 7) of Jiaojindui and its RC (over-standard 0.1-0.6 dB(A) at night). The MR project involves the existing primary trunk urban roads and secondary trunk urban roads in the city. At the time of prediction, no consideration was given to the noise reduction of noise-insulating windows. Based on the later field investigation, it was found that all the sensitive points of the project have been installed with double-layer insulating window glass, which can have a noise reduction of 20dB (A) or so. During the mid-term project operation, the night over-standard value at night is 0.5-2.2dB (A). Taking into HAES -78- Qinghai Xining Urban Transport Project Environmental Management Plan account the sound insulation of double-glazed soundproof windows of existing sensitive buildings, the indoor noise at each sensitive point can meet the requirements regarding limit values as specified in the "Sound Design Codes for Civil Buildings "(GB50118-2010). Therefore, the project operation has less effect on the acoustic environment sensitive points on both sides of the roads. 4.2.4.3 Measures for Prevention & Control of Water Environment Pollution (1) Sewage from the road sections of this project falls into the service scope of the Xining No. 1 Sewage Treatment Plant. The sewage along the roads is discharged into the municipal sewage pipeline system through sewer pipes and finally run into the Xining No. 1 Sewage Treatment Plant. The rainwater from the roads is discharged into the Huangshui River through the rainwater pipeline. Under normal circumstances, the content of runoff rainfall pollutants is low, which will not have a significant impact on the water environment. (2) It is necessary to regularly check and clear the rainwater drainage system to ensure smooth flow, and to maintain drainage facilities along the lines. (3) In order to protect the surrounding Nanchuan River and other water bodies, water pollution and traffic accidents caused by oil leakage and cargo dropping of vehicles should be prevented and controlled. On the bridge decks and abutments across the Nanchuan River shall be provided with warning signs like “cautious driving” and “slow down”.

Vehicles vehicle management strenghthen. Others HAES -82- Qinghai Xining Urban Transport Project Environmental Management Plan 4.4 Environmental Emergency Procedures Environmental emergency procedures relate primarily to the event of accidental leaks, spills, emissions and other unforeseen impacts or issues. Events related to adverse weather conditions will be addressed through the Project Activity Safety Plan (PASP) as part of the Contractor‟s Safety Plan, which will be submitted to the CSE before commencement of project construction works. The Safety Plan will be reviewed on regular basis and updated if necessary. The PASP will include procedures such as the prevention of slope slide / soil erosion during the rainfall season When accidental leakage or spill of diesel or chemicals occurs, the contractor should follow below standard procedure: 1) The person who has identified the leakage/spillage will immediately check if anyone is injured and will then inform the Contractor(s), CSE and EMC. 2) The Contractor(s) will ensure any injured persons are treated and assess what has spilled/leaked; 3) If the accidents / incidents generate serious environmental pollution or in the case that the CSE asserts that there is a potential of resulting in serious environmental pollution problems (e.g. spillage / leakage of toxic or chemicals, large scale spillage / leakage, or spillage / leakage into the nearby water bodies which are used for irrigation / portable water), the CSE will immediate inform the EPB; 4) In such cases, the Contractor(s) will take immediate action to stop the spillage / leakage and divert the spilled / leaked liquid to a nearby non-sensitive areas; 5) The Contractor(s) will arrange maintenance staff with appropriate protective clothing to clean up the chemicals/chemical waste. This may be achieved through soaking with sawdust (if the quantity of spillage/leakage is small), or sand bags (if the quantity is large); and/or using a shovel to remove the topsoil (if the spillage/leakage occurs on bare ground); and 6) Depending on the nature and extent of the chemical spill, evacuation of the activity site may be necessary. Spilled chemicals must not be flushed to local surface drainage systems. Instead, sawdust or sandbags used for clean-up and removed contaminated soil will be disposed of by following the procedures for chemical waste handling and disposal already described. The possibility exists for environmental emergencies of an unforeseen nature to occur during the course of the construction and operational phases of the project. By definition, the nature of such emergencies cannot be known. Therefore, the Contractor(s) will respond on a case-by-case basis to such emergencies and will initiate event-specific measures in terms of notifications and reactions. The Contractor(s) will prepare a report on the incident detailing the accident, clean-up actions taken, any pollution problems and suggested measures to prevent similar accidents from happening again in future. The incident report will then be submitted to the CSE, CESC for review and keep in the records. The incident report will also be submitted to EPB, if required. Most important of all, the Contractor(s) and all their workers working on the construction sites will be provided full and relevant training so that they are fully aware of the various HAES -83- Qinghai Xining Urban Transport Project Environmental Management Plan possible emergency situations in construction activities, the danger and potential damages caused by the emergency to the environment and the people, as well as the above emergency response procedures. If needed, drills will be conducted that the emergency procedures will be followed. 4.5 Communications and Continued Public Consultation Communication and public consultation are a continued effort throughout the construction phase, through the following measures: 1) All project sites will have an eye catching billboard, listing project information including but not limited to brief project description, construction time, main construction activities, project manager name and telephone number, chief construction supervisor name and telephone number and invitation to the public to communicate to these site management staff on any concern they may have. 2) Each contractor will be required to hold public meetings at the villages near their sites at least once a year. At the meetings, the site management will explain the construction activities and learn from the villagers on any concerns they may have and provide responses to their concern. 3) PMO will also have a full time safeguard staff whose partial responsibility will receive public complaints on project construction and operation. The PMO staff member‟s name and contact number will be made know to the local communities through pamphlets and public meetings. 4) PMO and contractors may visit from time to from key sensitive receptors such as schools and hospitals to understand any concerns they may have and how they feel about the impact of construction activities to the natural environments and their operations. 5) In preparation for special and high impact construction activities such as exploration, night time construction, the contractors will be required to visit the potentially affected communities to explain the activities and their impacts (e.g., safety risk, high noise, etc.), listen to the concerns from the communities and take appropriate and responsible measures to address the concerns raised. HAES -84- Qinghai Xining Urban Transport Project Environmental Management Plan Chapter 5 Environmental Supervision 5.1 Compliance with legal and contractual requirements The contractor(s) should prepare detailed and site-specific environmental protection implementation plan in the bid. The plan and other contractual requirements on environmental protection and pollution control should comply with relevant laws and regulations. All the works method statements submitted by the Contractor(s) to the CSE for approval will also be checked by the CSE to verify whether sufficient environmental protection and pollution control measures have been included. The Contractor(s) will regularly copy relevant documents including the updated Work Progress Reports and the updated Works Program to the CSE so that the verifying work can be carried out. The site daily record will also be available for the CSE's inspection upon his/her request. The CSE will advise the Contractor(s) of any non-compliance with the contractual and legislative requirements on environmental protection and pollution control for them to take follow-up actions. The Contractor(s) should respond accordingly, otherwise the CSE will not issue the construction order. 5.2 Site Supervision The CSE will closely supervise the construction activities through site inspections and the CESC will carry out daily site walks and visual inspections to identify areas of potential environmental problems and advise the Contractor(s) to take immediately remedial preventive actions. The area of inspection will cover both the construction areas and the environment outside the site area that could be affected, directly or indirectly, by the site activities. The CSE will organize regular joint site environmental inspections (for example, weekly inspections). The inspection will be joined by the CET and the PMO. The CSE will keep a log-book of each and every circumstance or change of circumstances which may affect the environmental impact assessment non-compliance with the recommendations of the EMP or the project contract. The log-book will be kept readily available for inspection by all parties including the Contractor(s) and the EMC. The CSE will make reference to the following information/documents in the inspection: 1) The Contractor’s environmental performance, EMP program, waste reduction, hazardous waste management and implementation of the required mitigation measures; 2) Good practices and general environmental mitigation measures provided in this EMP; 3) Compliance with the EMP requirements, contractual specifications and PRC legislation; 4) Protection to the sensitive locations and control mechanism of the restricted areas; 5) The Contractor’s construction methodologies and condition of construction site; 6) Individual works methodology proposals which will include proposal on associated pollution control measures; 7) Works progress and program; 8) The adequacy and efficiency of the Contractor’s pollution control measures / treatment facilities for minimizing environmental impacts, Landscaping and soil erosion controls; HAES -85- Qinghai Xining Urban Transport Project Environmental Management Plan 9) Location, management and pollution control at the waste / material storage areas, borrower pits and access roads; and 10) Previous site inspection findings and results. The Contractor(s) will update all relevant information of the construction contract for the CSE to carry out the site inspections. In the event of non-compliance / discrepancy and / or exceedance of the environmental quality criteria, corrective actions required for the Contractor(s) will be documented. The Contractor(s) will follow the procedures and time-frame as stipulated by the CSE in the environmental site inspection, and report any remedial measures subsequent to the site inspections. Weekly (or monthly) meeting will be organized after the inspection during which the Contractor(s) will report the progress of implementation of remedial actions identified in the previous inspections. Findings from the current inspection and the required improvements / remedial actions will be discussed. Minutes of meeting will be prepared by the environmental management team and distributed to all participants. The Contractor(s) will be required to implement the required measures within an agreed time. 5.3 Penalty System In the compliance framework, if non-compliance with environmental regulations are identified by CSE during the site supervision, contractors will be given a grace period to correct the non-compliance activities (i.e. two weeks). If the contractor performs the corrective actions within the grace period, penalties can be exempted. However, if the Contractor(s) fails to successfully make the necessary corrections within the grace period, they will pay the cost for a third party to fix the damages. 5.4 Environmental Complaints Complaints will be referred to the CSE for complaint investigation procedures. The CSE will undertake the following procedures upon receipt of complaint: 1) Log complaint and date of receipt onto the complaint database and inform the CSE immediately; 2) investigate the complaint to determine its validity, and to assess whether the source of the problem is due to works activities; 3) If a complaint is valid and due to works, identify mitigation measures; 4) If the complaint is transferred from the EPB, submit the interim report to EPB on status of the complaint investigation and follow-up action within the time frame assigned by EPB; 5) Undertake additional monitoring and verify the situation if necessary as well as review that any valid reason for complaint does not recur; 6) Report the investigation results and the subsequent actions to the source of complaint for responding to complainant (If the source of complaint is EPB, the results will be reported within the time frame assigned by EPB); and 7) Recording the complaint, investigation, the subsequent actions and the results in the HAES -86- Qinghai Xining Urban Transport Project Environmental Management Plan monthly EMP reports. During the complaint investigation, the Contractor(s) should cooperate with the CSE and provide all the necessary information and assistance for completion of the investigation. If mitigation measures are identified in the investigation, the Contractor(s) will promptly carry out the mitigation. The CSE will ensure that the measures have been carried out by the Contractor(s). HAES -87- Qinghai Xining Urban Transport Project Environmental Management Plan Chapter 6 External Environmental Monitoring 6.1 Introduction According to the project requirements, an environment monitoring consultant (EMC) will be selected by the client during the project implementation phase. The EMC will periodically collect all the indicators at sensitive sites (including the water, air, noise, etc). Such indicators will be submitted to the client as the reference to judge the performance of complying with the environment regulation. It is essential to design the monitoring program appropriately to be able to demonstrate both the overall performance of the project works as well as the short-term impact due to construction activities. As the integral and critical part of the EMP, the environment monitoring program has the following objectives: ⚫ Confirm the impacts forecasted in the EIA; ⚫ Determine the actual extent of impact; ⚫ Evaluate the effectiveness of the mitigation measures implemented on site; and ⚫ Identify and justify the additional mitigation measures against unexpected impact as may be necessary during project implementation and operation. 6.2 Impact Monitoring Impact monitoring during project construction phase, the selected EMC will conduct the regular site monitoring and inspections. During the peak construction period or at the request from the client, the EMC will also carry out additional measurements using portable equipments to monitor short-term impact. Once non-compliance with environmental quality performance criteria is identified, additional monitoring will be carried out. The sensitive sites with possible significant pollutions will be selected as the monitoring locations based on the results of the environmental impacts predictions. The environmental qualities at these locations will be monitored during the construction phase and the operation phase. The selected items to be monitored include the noise, ambient air and surface water. The monitoring indicators are identified based on the typical pollution factors of the Project. The analytical methods will be selected from relevant methods in the Technical Specifications of Environmental Monitoring issued by the legacy National Environmental Protection Agency. The national standards identified in the EIA process will be selected as the applicable standards. Based on the engineering characteristics of the Project, the environmental monitoring plan will be phased as shown in the Table 6.2-1 and Table 6.2.2.
