(YIES) for the World Bank financed Yunnan Honghe Prefecture Urban Transport Project (Mengzi City). During the project assessment, the EMP would be reviewed and approved by the World Bank financed Honghe Prefecture Urban Transport Project Office, and it will be implemented in project implementation phase. The purpose of the EMP is to propose measures or methods to eliminate, reduce or mitigate adverse environmental impact, so that it can be reduced to an acceptable level. To ensure an effective implementation of the EMP, in project preparation, the cost budget of the environmental protection measures were included in project cost estimate; the environmental mitigation measures were included in the technical specifications for procurement, bidding documents and implementation contracts; 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 Background Mengzi City is the key area in urban development group in south Yunnan. Centered by Mengzi and supported with Gejiu and Kaiyuan, is the so-call “Meng-Ge-Kai” urban group. In construct ion of this urban group, as the junction of Kunming-Hekou economic belt and the capital city of the prefecture that connecting coastal economic corridor, Mengzi becomes the core of the “Meng-Ge-Kai” urban group and the development core area. It is the center of politics, economy and culture of Honghe Prefecture. 1 With the great historical opportunity coming with China’s Development of the West Regions policy and the establishment of ASEAN Free Trade Area, Mengzi has shown its advantages on opening border, abundant resources and the “Development of the West Regions” policy. The city’s fast development has made it hard for existing urban transport system to meet the increasing traffic flow demand. Honghe Prefecture Government and Mengzi Municipal Government has paid much attention to the perfection and construction of the urban transportation system and have been actively seeking for finance from Word Bank. Through the implementation of Urban Transport Project in Mengzi, the radiating capacity of the city’s outbound transport system would be strengthened; the urban transport system could be constructed to be complete and sound; the city’s development principle as “stretching towards south and west” would be effectively guided, and the project would provide better direct municipal road infrastructure construction in urban development so as to realize the integration of transportation system, operation and management. Based on this, a rational road network structure for transportation would be constructed to provide guarantee for the development of the city. . Entrusted by the Implementation Agent, Kunming Design and Research Institute and Kunming Urban Transport Research Institute complied the Feasibility Research Report of the World Bank Financed Honghe Prefecture Urban Transport Project in Yunnan Province—Mengzi City. YIES was authorized by Project Implementation Agent to develop the EMP. 1.2 The EMP objective The purpose of the EMP is to develop a set of technical feasible, financial sustainable and operable environmental measures that specifically identify measures and arrangements for contractors, supervisors, operators and environmental departments to take in project implementation to mitigate and manage the environment impact and building up institutional capacity to eliminate or compensate any adverse social and environmental impacts to an acceptable level. The specific objectives of EMP include: （1）To identify environment management obligations of the contractors and 2 operators Environment Protection Bureau, environment assessing unit and the designing organizations would conduct on-site check and identify environment protection targets, develop effective mitigation measures and include them into the designing and contractual obligations for contractors and operators. （2）To working as environment management guidelines The proposed environment monitoring plans in EMP to be implemented in construction and operation periods can guarantee the effectiveness of the mitigation measures. It would be provided to supervising units working in construction and operation periods, environment monitoring units and other related departments to be environment protection documents to clarify the responsibility and roles of the functional departments, managing organizations as well as providing channels and methods for communication among various departments. （3）To guarantee fund for environment management actions. The cost estimate on environment management, monitoring, supervising and capacity building proposed in EMP has made it clear for all financing sources to guarantee all environment management actions can be implemented. 1.3 The design of EMP In order to elaborate the detailed content of environment management, supervision and monitoring, the proposed EMP would be the guidance for environment management throughout the project implementation. Its action plans mainly include the following 6 aspects: （1）Environment Impact and Mitigation Measures: main environment impact made during the construction and operation periods and the implementing and managing measures to prevent or mitigate the adverse impact. （2）Environment management system: setting up environment management organizations, clarifying monitoring and managing content and responsibilities and the supervising actions that guarantee implementation of environment protection measures in construction. （3）Environment monitoring plans: in order to eliminate environment pollutions, guarantee safe engineering and improve the environment condition of the project 3 area, external monitoring method would be adopted. （4）Environment management training plan: The plan is developed to provide knowledge and skill training for full-time and part-time management and environment supervising personnel working in project implementation to guarantee the fulfillment of the EMP. （5）Cost and organization arrangement: the implementation of EMP needs financial support from corresponding organizations. （6）Public consultation plan and complaint channels: to develop a sustainable public consultation plan and set up public complaint channels. 4 2 Environment Policies, Laws and Regulations 2.1 Related laws and regulations （1）Law of the People's Republic of China on Environmental Protection, December 26, 1989;

The main content would include cross section adjustment, dedicated lane construction, traffic 11 controlling, traffic calming, intersection transformation and transportation safety design. Honghe Avenue is trunk road, the transformation works starts from No.1 Road in Industrial Zone and ends on Xin’ansuo intersection, with a total length of 9.3m. The width of the road red line is 60m, which does not need to be widened. The colored asphalt roadside bus lanes would be paved and separated with social vehicles by greening belt. Fenghuang Road - Yinhe Road, a comparatively developed section with large number of electrombile trips has been selected for pilot electrombile experimental lane. The experimental section is 2.4 km. On bus stations, the electrombile lane would be canceled and combined with bicycle lanes. Upon leaving the bus station, electrombile lanes would be recovered as a separate one. The avenue would set up 15 signal control intersections with an average spacing of approximately 620m. On signal control intersections, traffic video surveillance systems, electronic police, traffic information collection system, traffic signal control system would also be equipped. Pedestrian crossing environment would be improved with the setting up of 23 intersection pedestrian crossings, 8 road pedestrian crossings with average spacing of 300 m. Traffic facilities like yellow flashing lights, electronic surveillance and signs like “Please take the sidewalk”, “Watch Out for Pedestrians” would be set up on pedestrian crossings. Integrated with intersection controlling forms and intervals between intersections along Honghe Avenue, traffic purification and speed management devices would be set. In most cases, they would be speeding bumps and dimensional pedestrian zebra stripes. （2）Jinhua Road: Between the new and old town in Wenlan District, because of the existing military land, there is no direct access connecting the two parts. The project would construct a north-south road as a supplementing east-west section so as to provide a more accessible route for urban traffic. The newly constructed Jinhua Road would be an extension of the existing North Jinhua Road. It starts from intersection on Xingsheng Road, passes Tianma Road and ends on Zhaozhong Road. The 1.30 km section forms 4 cross intersections and 2 T-shaped crossings with 6 roads in the old town. The planned width of road red lines is 32 m. The road would be constructed as standard two-way four-lane trunk road. Considering the impact on existing buildings along the both sides of the 12 road, geometry and openings, its designed speed would be 40km/h. Three circular curves would be set along the road with radius of 500m and 400m. （3）Zhaozhong Road: Now, there is no linking on east-west direction between the new and old town in northeast part of Wenlan district. A 30m wide extension of Zhaozhong Road would be build to connect the existing feeding roads to fill the missing east-west section so as to improve the accessibility of the urban road network. It is proposed to construct a 770m long missing section between Zhaozhong Road and Lianda Road and form a T-shaped crossing and 1 intersection with West Renmin Road and Jinhua Road. The section’s width of road red line would be 30m and it would serve as an east-west secondary main road on northeast part of Wenlan District linking the new and old town. The section would be constructed in two-way four-lane standard with design speed of 40km/h. （4）Xuefu Road: To construct a new transporting road to the east of Honghe University campus and to take measures to transform the function of the existing Xuefu Road so as to integrate it into the campus transportation system. The new road starts from Guanyin Bridge to the intersection connecting with Honghe Avenue, with a total length of 3km/4.1km and 36m width of road red line. The road class would be main road in two-way four-lane standard with designed speed of 40km/h. Along the road, the section would form 3 T-shaped crossings and 8 intersections with 11 roads, with a total length of 3.99km and 36m width of road red line. It would serve as the main access that links Honghe University with the new and old town. Along the section, three circular curves and two turning points would be set. The biggest circular curve radius would be 1000m and the smallest would be 800m. 3.2.1.2 Roadbed and Pavement （1） Roadbed In addition to consider the roadbed design elevation to ensure basic drying and drainage need, the strength and stability of the roadbed, there is also consideration for planning road network along the roads, smoothing access to land openings, keeping construction convenient, drainage flow and others 13 ① General roadbed design In construction of the roadbed, much attention should be paid to drainage. It would have no ponding on construction surface and the embankment constructed with 2% -4% drainage cross slope. When the transverse slope of the filled section is smaller than 1:5, direct filling can be conducted. When it is bigger than 1:5, terraces should be dug on the original ground with width no less than 1.0m, and then construct a 2% -4% drainage cross slope. The backfilling of the roadbed should be gravel. If there is cultivated soil before backfilling, clean it first. The designed slope excavation is 1:1 and the filling slope is 1:1.5. The filling subgrade prefers good graded gravel soils, sandy soil and other granular soil to be filler. Road bed compaction is bigger than 0.96 (0.0-0.8m underground below the bottom surface of the pavement), road embankment compaction is more then 0.94 (0.8-1.5m underground below the bottom surface of the pavement), the road embankment compaction is more then 0.93 (less than 1.5m underground below the bottom surface of the pavement), the base layer compaction is more than 0.98, and the subbase layer compaction is more than 0.97. ②Special roadbed processing Soft soil subgrade: for sections with sludge and soft soil, first drain and dewatering the part, cleasen the silt pond and fill it with 0.5m-1m slice rocks, then put soil-rock mixture to the level of the original ground and finally lay a layer of geogrid. For small area with soft ground, the approach of throwing stones to packing sedimentation can be directly used. For deep soft ground, deep piling would be applied according to the characteristics and distribution of soft soil. Roadbed in fill section: first cleanse the tree roots, sod and humus soil; then the paved embankment should be stratified, the thickness of loose lay should not exceed 30cm, then compact it uniformly. In fill section, if the original ground is low-lying or with high underground water level, the embankment base shall be designed with drain isolation cushion layer with 0.5m of good water permeability gravels and geomembrane as a filter layer on top. In high fill section (over 3m), a layer of geogrid should be laid 30cm under the pavement structure, another layer of geogrid 50 cm under the first one. Totally, there are two layers of geogrid to reinforce the stability of embankment. 14 Roadbed in Excavation section: within the road, expansive soil on cutting and roadbed within 0.8m wide area should be overexcavated and then fill with required fillings and strengthen the drainage measures. Subgrade border processing: When excavation area is soil, it should be reclaimed with materials with good water permeability and at the same time, within 0.8m of excavation, conduct overexcavation, backfilliing and compaction on the soil and put two layers of 10m wide geogrid at the junction of road bed, extend it to 2-3 meters of the excavated part and 7-8m of the filling part. ③Splicing treatment of the new and old roadbed To reduce uneven settlement between the new and old road and postpone the appearance of radiating cracks, it is designed to excavate pavement structure within 2m splicing area to pave it together. 2 layers of 2m wide geogrid would be put separately on top and bottom surface of the roadbed to make the new and old roadbed together as a whole. （2）Pavement The pavement of the road should be based on the requirement of the traffic and use as well as the natural conditions like climate, water level and geology, following the principle of adjusting measures to local conditions, reasonable selecting materials and good for construction, to identify a proper designing plan for pavement structure to enable it with a good stability and strength to meet the specifications and meet the requirement of smoothness, skid resistance and drainage.

The project will acquire 29.62hm2 of land for farmland, garden, constructive and transport land, which will not change the land structure, and little effect the land utilization. 64 (2) In the project, there is human−caused disturbance to some extent，where the vegetation types are mainly occupied by farmland and orchards. Farmland and orchards are locally common artificial vegetation, of which biodiversity is not enormous. Therefore, the construction of the project will not result in any vegetation types in the region disappearing, nor will the local vegetation ecosystem produce adversely affects to the local vegetation ecosystem stability conditions. (3) In the project, plant species in the evaluation region are mainly dry land crops, pomegranate, loquat fruit and a small part of the tree species without national and provincial protection of plants or plant specific to the region or distribution of ancient trees as well as famous wood; Wildlife within the region are mainly living species associated with people with fewer quantities and species. There are no national and provincial protected species, rare and endangered species and endemic species, also not involved in animal migration routes. Hence, although the project will result in the reduction of animals and plants individuals in the land occupied in a certain range of time and space, but it will not have a significant impact on the species diversity, which is less effective on the animals and plants. (4) During the project construction, it needs removal of part of house buildings and destroy of some landscape elements, which has undermined the local area landscape to some extent; during construction it needs foundation excavation, earthwork, stacking of construction materials or randomly parking and placing of temporary buildings or machinery, which will affect the environment and urban landscape as well as urban sanitation; the noise, flying dust, ambient air, construction waste and drainage water during construction will pollute the surrounding environment and bring some damage to the urban landscape. The above effects all take place during construction phase, which will gradually disappear in the end of the phase. (5) After the completion of the project, native trees will be used in newly established and modified roads so as to enhance the proportion of afforestation. The rational allocation of green belts can play a role of protecting pavements, reducing soil erosion, traffic dust and traffic noise, regulating and improving microclimate of roads and other integrated environment efficiency, thereby improving the environment along the landscape so as to beautify the city. 65 4.4 The Impacts of Water Environment 4.4.1 Construction Phase The wastewaters are mainly from the domestic wastewater of the construction workers, the cleansing water of the construction machineries or vehicles, and the wastewater of construction. (1) During construction, relying on the Mengzi City, the living camp site is not established in the construction area, but there are a small amount of personnel on duty (about 5 to 10 people), which will produce a small amount of domestic wastewater of with the concentration of main pollutants are: BOD5167mg/L 、 CODcr350mg/L、SS250mg/L、NH3-N25 mg/L、phosphate 5 mg/L. Calculated as 100L per person per day with wastewater discharge accounting for 80%, the maximum of domestic wastewater is about 0.8m 3/d. The amount of discharged domestic wastewater is not huge, and the dust from construction sites after temporary treatment of simple sedimentation tank will not be discharged. There is little effect on the surface water environment. （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 water of concrete manufacturing and the waste is 34m3/d. The washing of machineries and vehicles will produce a large amount of wastewater with high sand content, which is 9 m3/d. 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 not be allowed to discharge 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 discharge into the rivers. 4.4.2 Operation Phase During the operation phase, the wastewaters are mainly from the domestic wastewater of the staff members and other people, the oil containing wastewater of the vehicles maintenance, the Gas Station, and the road runoff. 66 （1）Wastewater from Central Bus Station and Terminal The output, treatment measures and discharge destination of Interchange, initiating stations and terminal are shown in Table 4.4-1. Table 4.4-1: Output, Treatment Measures and Discharge Destination of Interchange, Initiating Stations and Terminal Type of Treatment measures and discharge No. Name Output（t/a） wastewater destination Domestic Wenlan Datiepu United 10.62 wastewater 1 Central Bus-Railway Oil containing Station (incl. terminal) 1.2 wastewater The oil containing wastewater will be Domestic discharged into the municipal 11.26 wastewater pipe network with domestic wastewater wastewater after oil separation Central Bus Station pretreatment and enter the Mengzi City 2 (incl. terminal) Oil containing Treatment Plant for processing. 1.2 wastewater Domestic 8.71 wastewater 1 small set of sewer treatment is Yuguopu Central Bus configured inside the station, which can 3 Station (incl. terminal) Oil containing reuse after treatment and reach the 1.2 wastewater standard.

Wastewater treatment plant of Mengzi City is located in Lijiang River beside Shilupu and put into production and operation in January 2005. It covers 40 acres and adopts ICEAS technology, which has obtained the EIA approval. The designed processing capacity of the first stage of project is 20k tons/day, with the maximum processing capacity of 28,000 tons / day, which will be discharged in accordance with the national level B standard. After put into operation, various types of equipment are run in good condition, of which treatment process and technical parameters all meet the design requirements. The engineering project of second phase adopting ICEAS technology is 20k tons/day. Currently the construction process has been completed, while the machinery and equipment are waiting for installation. The treated effluent will be discharged in accordance with the national level B standard. 67 （ 2 ） The wastewater from the roads during operation phase is mainly composed of the rain water, whose major pollutants include the SS and the COD. The rainwater from some sections of Jinhua Road pipes into the South Lake through storm sewer, while the rainwater from other sections of Jinhua Road, Zhaozhong Road and Xuefu Road pipes into Lijiang River through storm sewer. 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. The road should be promptly cleaned to minimize rainwater pollution. （3）The roads to be constructed in the project are mainly urban roads that do not be allowed transportation of hazardous chemical. Therefore there is no risk of water pollution caused by accidents of vehicles loaded with hazardous or poisonous substances. 4.5 The Impacts of Acoustic Environment 4.5.1 Foundation Excavation of Construction Phase According to the Emission Standard of Environment Noise for Construction Site (GB12523-2011), the environment noises for the construction site are respectively at 70 dB daytime and 55db at night. The prediction results showed that: noise of construction machinery more than 50m away in the daytime （≥50m）can meet the requirements of 70dB (A) standard limits; while machinery noise in the night time during construction more than 280m away （≥50m）can meet the requirements of 50dB (A) standard limits. Thus, the impact of construction machinery noise on construction sites around the 50m-wide environmental is larger, especially serious of nighttime during construction period. Jinhua Road, Zhaozhong Road and Xuefu Road in this project are all newly constructed roads, especially Jinhua Road and Zhaozhong Road located in the densely populated regions in Mengzi. Most residential areas are close to the roads, which are distributed within the 16-200m ranges on both sides of the new highway centerline. Therefore, the machinery noise during construction will cause impact of various degrees, which should take effective measures to reduce the impact of the construction period. 68 4.5.2 Operation Phase （1）The Prediction Results of the Traffic Noise at the Sensitive Sites Zhaozhong Road: 17 sensitive sites reach the standard during operation while 7 sensitive sites are over standard, where Tianma Community is 0.7 dB over standard during nighttime in the forward period; the Second Dormitory of Sinopec's Mengzi Company is 0.6 dB over standard during nighttime in the mid period; Mengzi Yuxin Arts Preschool is 0.4 dB over standard during nighttime in the mid period; Hongyan Community is 0.9 dB over standard during nighttime in the forward period; Yuyatang Community is 0.1 dB over standard during nighttime in the forward period; the Dormitory of No.3 Mengzi Middle School is 0.8 dB over standard during nighttime in the forward period; No.3 Mengzi Primary School is 0.2-5.1 dB during nighttime in the forward period. Xuefu Road: 4 sensitive sites reach the standard during operation while 1 sensitive site is over standard. The over standard site is Dongcun, which is 0.5 dB over standard during nighttime in the forward period. Jinhua Road: 9 sensitive sites reach the standard during operation while 6 sensitive sites are over standard (Dayuanzi, Yufeng Hotel, Honghe Caring Hospital, Armed Police Hospital, No.9, 10, 11 Qilong Community, No.3 Mengzi Primary School). In which Daziyuan is 0.4 dB over standard during nighttime in the forward period; Yufeng 0.4-1.5 dB; Honghe Caring Hospital is 0.3-7.8 dB over standard during nighttime in the mid and forward period; Armed Police Hospital is 1.0 dB over standard during nighttime in the forward period; the No.9, 10, 11 Qilong Community is 1.1-2.3 dB over standard during nighttime in the mid and forward period; the 0.2-5.1 dB over standard during nighttime in the mid and forward period. （2）The Prediction Results of the Traffic Noise near the Bus Corridor According to the feasibility study report, after implementation of bus corridors project, the designed average daily traffic volume is increased to some extent compared with the current traffic volume. According to the relevant literature predictions, in case of equal distance of road, the noise of observation point near the bus stop is increased by 2dB than the noise of the observation site away from bus stop. Therefore, after the creation of bus corridors, the sensitive sites near the bus stop will increase. Noise of sensitive sites near the bus stop will be greater than 69 before construction. At the same time, because of the smooth flow of road traffic, the traffic noise is decreased in a certain extent compared with the idle state. In addition, with the convenience of transit service continues to improve, more and more citizens will be attracted to choose to travel by bus. （3）The Prediction Results of Central Bus Station and Terminal The project has set up 5 interchange, initiating stations and terminal, of which the evaluation scope of Initiating Station and terminal in the northwest of the Municipal Administrative Center and Yuguopu Interchange does not involve sensitive sites. Wenlan Datiepu Railway-highway Combined Transport Interchange is about 160m away from the nearest sensitive site. After sound insulation and geometrical spreading model, the impact of Interchange is small on sensitive sites. The Interchange of terminal station and Initiating Stations and Terminal south towards east from Beijing Road both involve 1 sensitive site. The nearest distance of Interchange is 30m away from the Luyingcun. There are 10 operating lines set in the Interchange, and a demand of 118 cars parking. The large traffic flow will bring certain noise impact on Luyingcun. The nearest distance of Initiating Stations and Terminal south towards east from Beijing Road is 30m away from Shuigoucun, which has 4 operating lines with 29 buses. Since there are no overnight parking in the Initiating Stations and Terminal, there will be less impact on the Shuigoucun. 4.6 The Impacts of Ambient Air 4.6.1 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 Environmental Air Quality Standards (GB3095-2012). 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 Environmental Air Quality Standards (GB3095-2012). 70 （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 meeting the Class II standard of the Class II standard of Environmental Air Quality Standards (GB3095-2012). 4.6.2 Operation Phase （1）According to the analogy results of Tinama Road south extension at Mengzi City, the NO2 and the CO concentrations are both meet the Class II standard of the standard requirements of Environmental Air Quality Standards (GB3095-2012). 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 exhaust gas will be reduced. For the bus stations and the interchange, the normal operation will not cause significant impact on the ambient air environment. （3）After the gas station construction, the exhaust gas is mainly originated from two substances: non-methane hydrocarbon (NMHC) which is from the loss of large and small tank breathing and oil spewing fluid; and the tail gas of the vehicles at the gas station. Because there are underground storage tanks and self –sealing nozzle, together with the recovery system, the air pollutant, NMHC, will be discharged. The exhaust pipe is no less than 4 meters in the ground, and the volume is no less than 25g/m3, which are both in compliance with the standard requirements of the Gas Station Air Pollutant Emission Standards (GB20952-2007). The boundary NMHC volume is below the limit required ≤4.0mg/m3 by the Air Pollutant Emission Standards (GB16297-1996), which will not affect the sensitive sites. 71 4.7 The Impacts of Solid Waste 4.7.1 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 290,500 m³, the fill volume will be 184,000 m³, in which 41,300 m³ from internal transportation, and 50,100 m³ are borrowed (from the river bridge construction project). The waste earth volume will be 156,600 m³, including permanently abandoned 131,500 m³ (all for building demolition waste, removal of existing roads and green belts), temporarily abandoning 25,100 m³ (all for stripping topsoil, temporarily stacked in Xuefu roadbed within five topsoil temporary yards, for post-road green casing). Since the Mengzi municipal government is responsible for the organization and implementation of project resettlement work, the 131,500 m 3 permanent spoil produced will be transported to the designated residue site in accordance with the relevant provisions. The construction units are committed to strictly follow the relevant provisions of construction waste disposal, sign contracts with the qualified processing units in the next stage which expressly indicating that no residue can be abandoned randomly, legal and reasonable disposal of residue. The construction waste transport and processing units are responsible for the soil and water conservation projects outside the construction region. The residue disposal and deployment will be recorded by the local water administrative department as a basis for acceptance. The situation of earthwork which flows is shown in Table. 4.7-1, while earthwork balance calculations are shown in Table. 4.7-1. There are about 150 people in the construction site during the peak of construction, with generating about 0.15 domestic wastes every day; the domestic waste will be sent to the Mengzi sanitary landfill for disposal. During 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. 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, 72 construction management should be strengthened to clean up the solid waste promptly to reduce or prevent the above-mentioned impacts. 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. The solid wastes that cannot be recycled will be sent to the Mengzi sanitary landfill for disposal. The Mengzi sanitary landfill is located in Chenjiazhai, southwest of Mengzi City. It was put into operation in June 2007, covering about 10.5 hectares with a designed service life is 15 years. The total capacity of landfill site is about 1.48 million cubic meters with an effective storage capacity of about 1.28 million cubic meters and daily waste processing of 200 tons. It adopts semi-aerobic landfill treatment process, which has obtained the EIA approval.

The main accident risk in this project is explosion risk at interchange gas station. The gas station technical parameters are shown in Table 4.8-2. Table 4.8-2 The Gas Station Technical Parameters Total fuel Total driving Maximum fuel Total volume of consumption Name distance per consumption of design oil tank each month day (km) bus (m3/km) （m3） （m3） Wenlan Datiepu Railway-highway 11695 2.8*10-4 98.238 110 Combined Transport Interchange Passenger Hub 14121.9 2.8*10-4 118.624 120 Interchange Yuguopu Interchange 575.9 2.8*10-4 48 55 According to Construction Project Environmental Risk Assessment Technical Guidelines (HJ/T169-2004), the environmental risk assessment grade is divided. The factors are based on the evaluation of the project's physical hazard, functional 80 unit major hazard determination result, and environmental sensitivity as well as other factors. The project mainly stores diesel and decided according to the risk guidelines of flammable substance name and critical mass determination in Table 3 of Appendix A1. Therefore, according to Table 4.8-3, the production and storage sites of this project are both significant hazards. Table 4.8-3 Flammable Substances Stock and Critical Mass Comparison Name of Critical mass（ton） Actual storage capacity（ton） substance Initiating station and Production Storage Wenlan terminal at Beijing Yuguopu site site Datiepu Road south Interchange extension Gasoline 2 20 82.5 90 41.2 Note: As diesel is involved in this project while where no diesel in guideline, so this project will be implemented with gasoline reference, oil density is calculated according to 0.75 After hazardous substance identification and analysis of the production process, according to requirements of Construction Project Environmental Risk Assessment Technical Guidelines (HJ / T 169-2004) and Major Hazard Identification (GB18218-2000), the identification of major hazard is based on substances dangerous characteristics and quantity. The diesel storage capacity in this project is over than the critical mass that set forth in standard (GB18218-2000), which is referred to as major hazard. According to the table 4.8-4, major hazard source is present in the storage place of the project. The project risk assessment will be assessed as per the first level.
