6 I. INTRODUCTION A. General 1. As per the Project Agreement for the Gansu Baiyin Urban Development Project (the project), the Government of Gansu Province, Baiyin Municipal Government, and each Project Implementation Agency (PIA) shall ensure that (i) the project be constructed and operated in accordance with the national and local environmental regulations and guidelines, Environmental Policy (2002) of Asian Development Bank (ADB) and the environmental impact assessment (EIA) reports; (ii) any adverse environmental impacts arising from the construction and operation of the project facilities be minimized by implementing the mitigation measures, environmental monitoring program and other recommendations presented in the EIA reports; and (iii) the implementation of the environmental management plan (EMP) and violations of safety or environmental standards, if any, be regularly reported to ADB. 2. The project consists of five subprojects, of which four construction subprojects involve environmental monitoring, including (i) Southern Baiyin Infrastructure, (ii) Baiyin District Road Improvements, (iii) Pingchuan District Road Improvements, and (iv) Baiyin District Heating Services. The construction for these four subprojects has substantially completed. The fifth subproject is the Capacity Development and Institutional Strengthening, which is a consulting service and does not involve any environmental monitoring. Under this subproject the consultants provide assistance to the Baiyin ADB Project Management Office (PMO) and PIAs in completing the environmental monitoring requirements and preparing monitoring reports. 3. The environmental specialists from the consulting firm and the PMO staff visited the project sites during this reporting period. During the visits, in depth discussions were made with the PIAs, during which the particular attention was focused on their responsibilities for environmental monitoring and preparing monitoring reports. The Baiyin Municipal Environmental Monitoring Station of Baiyin Environmental Protection Bureau (EPB) contracted by the PMO monitored the environmental conditions in accordance with the EMP. 4. This semi-annual environmental monitoring report describes the implementation of the environmental monitoring and mitigation measures recommended in the EIA reports, analyzes environmental data collected from the related subprojects during the period of July through December 2012, and provides recommendations on issues identified. 5. Specifically, this environmental monitoring report covers the following areas: (i) documentation review and compliance assessment with the applicable environmental regulations and standards, (ii) environmental management institutional structure and responsibilities, (iii) mitigation measures undertaken by the contractors to minimize adverse environmental impacts arising from the construction of each subproject, (iv) environmental monitoring results and analyses, and (v) conclusions and recommendations. 1

7 B. Basis of the Report 6. This semi-annual environmental monitoring report has been prepared based on the data and information from the following sources: Environmental monitoring reports provided by the Baiyin Environmental Monitoring Station of the Baiyin EPB; EIA reports for all subprojects; Environmental supervision reports provided by each PIA; EMP submitted to ADB; Project Agreement; and Relevant environmental laws, regulations and standards. C. Environmental Procedure Review 7. The consultants reviewed the environmental monitoring procedures and data collections with the PMO and PIAs. Each of the contractors, construction supervision companies, and the PIAs designated staff from the site management team plays an important role in environmental monitoring and supervision. The responsibilities of the staff include day-to-day site environmental monitoring of their own contracts, implementation of mitigation measures as indicated in the environmental action plan, and reporting of the site s environmental performance as specified in the contract including self-inspection and self-monitoring. 8. Most of the environmental monitoring requirements are for the construction period of each subproject. At the construction stage, the construction supervision companies are responsible for the preparation and submission of monthly environmental supervision reports; meanwhile, the environmental monitoring agency is responsible for the monitoring of environmental parameters and preparing environmental results reports. The PMO designated Ms. Zhang Qiong, with an environmental background, to serve as an environmental officer for this project. The PMO, with the assistance from the consultants, is responsible for compiling the semi-annual environmental monitoring reports. The specific responsibilities of the PIAs, contractors, local environmental monitoring stations, and construction supervision companies have been identified and communicated with relevant parties with training provided and they are summarized as follows: PIAs: Develop the environmental section of the contract with the assistance from the consultant; Provide training to contractors and all other related environmental personnel; Visit project sites and review results; Resolve environmental complaints, if any; 2

8 Develop and implement pollution prevention measures; Implement environmental monitoring plans; Provide monthly environmental monitoring reports to the PMO; Implement mitigation measures including environment, health and safety; and Arrange environmental meetings as necessary. Local Environmental Monitoring Stations: Prepare an environmental monitoring plan; Conduct on-site environmental monitoring; and Prepare reports based on the monitoring data collected. Supervision Companies (during the construction period): Supervise implementation of environment protection and mitigation measures; Perform environmental management responsibilities; Receive complaint calls and participate investigations; and Report environmental issues on sites. Contractors (during the construction period): Implement environmental mitigation measures; Provide environmental and safety training to its workers Provide basic sanitation facilities to onsite workers; Perform treatment of domestic sewage generated at construction sites; Manage and dispose solid waste generated from construction sites; Implement noise and dust control measures; Provide personal protective equipment for workers; and Take measures to ensure that construction equipment meets relevant national or local emissions and noise standards.

10 II. SOUTHERN BAIYIN INFRASTRUCTURE SUBPROJECT A. Scope of Subproject 10. This subproject originally plans to develop, as part of the Southern Baiyin Industrial Park (SBIP), 5.6 km 2 of industrial land with basic public infrastructure, including km of primary and secondary roads and related water supply pipelines, drainage pipelines and sewers, heating supply pipelines, optical-fabric cable and electricity distribution lines, lighting, and public green areas. 11. The scope of this subproject was revised in 2010 to (i) avoid removal of key facilities of Yinguang Company, such as evaporation pond and explosive warehouse; (ii) avoid relocation of Cha Chuan Channel, which provides irrigation water for more than 2,000 mu of farm land for downstream villages, and avoid acquisition of farmland on southern of Nanweierlu Road; and (iii) improve land use efficiency of the west part of the industrial park. Optimization of the subproject scope resulted in reduction of 5.95 km of road construction works for four roads: Nansanhuan Road, Nansihuan Road, Nanjingerlu Road and Nanweisanlu Road, and the industrial land area for development was also reduced to 4.7 km 2. B. Subproject Progress 12. There are three procurement packages (two national competitive bidding and one international competitive bidding) under the ADB loan for this subproject. They are all civil work packages including: package C01 - Earth Work, package C02 - Southern Baiyin Infrastructure #1, and package C03 - Southern Baiyin Infrastructure #2. The constructions of all civil work packages of the Southern Baiyin Infrastructure Subproject were ongoing during the reporting period, except for Zhisan Road and Nanweier Road. 13. The accumulative investment completed since start of the subproject was CNY million, which accounted for 75.2% of the total investment. From July to December 2012, the contract amount completed was CNY25.62 million. C. Environmental Management Office 14. An environmental management office was established under the Land and Environment Protection Bureau of the SBIP to monitor the implementation of the EMP. The SBIP Management Commission appointed Mr. Zeng Chengfu, the chief of the bureau, to be responsible for the environmental management of this subproject during the construction period. 5

11 D. Environmental Monitoring 1. Air Quality Monitoring 15. Four air quality monitoring locations near the construction sites were selected, on Nansanhuan Road, Nansihuan Road, Nanweiyi Road, and Nanweierlu Road respectively, as the monitoring stations. They were located approximately within 200 m from the site boundary. The locations of the monitoring sites are shown in Figure 1. Both the total suspended particle (TSP) and PM 10 were monitored for two days each month from July through December 2012, and two samples were taken each day. In total there were 96 samples taken for TSP and PM 10 each. The results of the air quality monitoring are included in Table 1.

The applicable standard used for ambient air quality and compliance evaluation is the Ambient Air Quality Standards (GB ). According to Table 1, for TSP the minimum value was mg/m 3 and the maximum value was mg/m 3. The average TSP level was 0.31 mg/m 3, close to the 24-hour average national standard of 0.30 mg/m 3. Forty-seven out of the 96 samples (approximately 49%) are higher than the national standard of 0.30 mg/m 3. For PM 10, the minimum value was mg/m 3 while the maximum value was mg/m 3. The average PM 10 level was mg/m 3. Only one of the 96 PM 10 samples (1%) was higher than the national standard of 0.15 mg/m The background TSP and PM 10 concentrations in Baiyin urban area were also collected by the Baiyin EPB. The four monitoring sites for TSP were around Gansu Hualu Aluminum Co. Ltd., while the two monitoring sites for PM 10 were around Dynamics Company and Yuyuan Restaurant, as shown in Figure 2. The monitoring results are shown in Table 2 and 3. Figure 2: Monitoring Locations for Background Air Quality in Baiyin Gansu Hualu Aluminum Co. Ltd. 9

Baiyin is located in the semi-arid northwest part of the People s Republic of China (the PRC), where ground vegetation coverage is very low and surface soil is exposed to ambient environment. There are many small dust particles in the air when wind blows and this results in the high baseline of TSP in Baiyin. As it can be seen from Table 2 that the 10

16 background TSP values ranged from mg/m 3 to mg/m 3. The latter was more than four times of the national standard of 0.30 mg/m 3. The average value was mg/m 3, about double the standard. Only 5 out of the 20 samples were in compliance with the national standard. Compared with the background data, the TSP level of the construction sites (0.31 mg/m 3 in average) under the subproject were much lower, indicating that the mitigation measures required in the EMP were effectively implemented, as detailed later in Subsection E. 19. Similarly, from Table 3 we can see that more than half of PM 10 concentration values were higher than national standard of 0.15 mg/m 3, and the maximum background PM 10 concentrations reached mg/m 3 in December 2012, which exceeded twice of the national ambient air quality standard for PM 10. In contrast, the PM 10 level of the construction sites were well controlled, with only one data point slightly above the standard. 2. Noise Monitoring 20. Noise was monitored in the areas affected by the subproject around the site boundary during the construction period. The monitoring locations for noise are the same as that for air quality as shown in Figure 1. The monitoring lasted for one day each month from July to December 2012, and the equivalent continuous A-weighted sound pressure level (Leq) was measured once during daytime (from 6:00 to 22:00) and another time at night (from 22:00 to 6:00). 21. The applicable standard used for noise monitoring and compliance evaluation is the Standard of Noise at Boundary of Industrial Enterprises (GB ). The area where monitoring locations were located is the 3rd category sound environmental functional area 1, where the upper noise limits for daytime and night are 65 db(a) and 55 db(a), respectively. The noise monitoring results are summarized in Table 4 and indicate that the recorded noise results were all in compliance. This demonstrate that the noise mitigation measures were adequately implemented during the reporting period. No. Table 4: Noise Monitoring Results for Southern Baiyin Infrastructure (Leq [db(a)]) Daytime Night Time 20 Jul 14 Aug 9 Sep 15 Oct 11 Nov 3 Dec 20 Jul 14 Aug 9 Sep 15 Oct 11 Nov 3 Dec Definition of sound environmental functional area category: Category 0: Convalescence area, Senior villas, Senior hotel etc., 50 db(a) daytime; 40 dm(a) at night; Category 1: Residential area, Institutions of culture and education, 55 db(a) daytime; 45 dm(a) at night; Category 2: Residential area, Mixed area of business and Industry, 60 db(a) daytime; 50 dm(a) at night; Category 3: Industrial park, 65 db(a) daytime; 55 dm(a) at night; Category 4: Area on the both sides of urban arterial road, Area on the both sides of canal across the city, Area on the both sides of railway, 70 db(a) daytime; 55 dm(a) at night; 11

17 Source: Baiyin EPB. E. Mitigation Measures Implemented and Compliance Assessment 1. Dust Suppression 22. The contractor implemented dust control measures, including developing a dust suppression program of timely backfilling at the construction site and water spraying to suppress fugitive dust emissions. Particularly, in dry and windy conditions, water spraying was conducted more frequently. Construction materials were covered to avoid fugitive dust. 2. Noise Control 23. Construction time was properly planned from 7:00 to 18:00, and the contractor did not perform work at night. The construction sites were far from the sensitive points, such as residential area, school and hospital, etc. Construction equipment with low noise was used and located as close to the center of the site as possible during the construction period. 3. Wastewater Control 24. Wastewater generated from the site minimized and collected to be discharged to septic tanks or the municipal sewer system for further treatment to avoid secondary pollution. 4. Solid Waste 25. The soil from the earth work was appropriately used and timely transported out to a designated place. A guard net was employed during transportation to avoid fugitive dust. The other solid waste was collected and properly disposed to the designated area. 5. Compliance with Safety or Environmental Standards 26. No violations of safety or environmental standards was reported during the reporting period except some high TSP concentrations identified above. F. Issues and Recommendations 27. A few monitored TSP and one PM 10 results under the Southern Baiyin Infrastructure Subproject exceeded the national standards. Given the high background level in Baiyin area, it can be concluded that the impact on the local air quality by the construction sites were adequately mitigated. The relevant mitigation measure should be maintained and further strengthened in the future as necessary. 12

18 III. BAIYIN DISTRICT ROAD IMPROVEMENTS SUBPROJECT A. Scope of the Subproject 28. This subproject originally planned to (i) construct nine new roads with a total length of 23.1 km; and (ii) build connected water supply pipelines, drainage pipelines, sewers, heating supply pipelines, lighting, bus rider/pedestrian and bicycle facilities. This subproject will also build 14 bridges/culverts and rehabilitate and widen three existing roads with a total length of 6.1 km. 29. There was a change of scope of this subproject in 2011, which included: (i) removal of 3.2 km of road sections from East Binhe Road and West Binhe Road as per the reprioritized urban transport development plan; (ii) extension of rehabilitation works of Fangzhi Road by 451 m to ensure the smooth and constant traffic along the whole road; and (iii) additional rehabilitation and maintenance works for six primary or secondary roads in Baiyin District. B. Subproject Progress 30. After the mid-term scope adjustment, the subprojects included seven contract packages. The updated cost estimates were CNY4,011 million. By the end of 2012, the completed investment was CNY33.4 million, accounting for 83.35% of the total. 31. During the reporting period, the roads of Nanhuan Road, East Binhe Road, West Binhe Road, Jingsan Road, Weier Road, Gongyuan Road, West section of Yejin Road, Gongnong Road, Dongshan Road, Chengxin Road, and East Jianshe Road were all under different stages of construction. Lvchang Road and Fangzhi Road involved some greening and lighting works. C. Environmental Management Office 32. The Baiyin City Construction Bureau appointed Mr. Wang Dongye as the responsible manager for the environmental management of this subproject as required by the EMP. D. Environmental Monitoring 1. Air Quality Monitoring 33. A total of twelve air quality monitoring locations located approximately 200 m from the construction site boundary were selected as the monitoring stations, which included i) residential area north of Dijiatai Village; ii) residential area south of Dijiatai Village; iii) residential area east of Dijiatai Village; iv) Chengxin Road; v) residential area west of Yejin Road; vi) residential area east of Yejin Road; vii) residential area north of Dongshan Road; viii) residential area along Dongshan Road; ix) residential area south of Dongshan Road; x) residential area north of Gongnong Road; xi) residential area along Gongnong Road; and xii) 13

19 residential area south of Gongnong Road (see Figure 3 and 4). Three types of parameters, i.e. TSP, PM 10, and NO 2, were monitored for three days in November. The monitoring results are presented in Table 5.

22 Average Source: Baiyin EPB. 34. As shown in Table 5, the maximum value of TSP was mg/m 3, being 18% higher than national limit of 0.30 mg/m 3. Although 30 out of the 36 samples (approximately 83%) had the daily values for TSP higher than the standard, the average TSP value of mg/ m 3 was only 12.7% higher than the national standard. This non-compliance is much less serious than the background data of mg/m 3 as shown in Table 2, which is about 91.7% higher than the national standard. 35. For PM 10, the maximum daily value was mg/m 3, 4.6% higher than the national standard of 0.15 mg/m 3. Eight out of 36 samples (approximately 22.2%) had daily values slightly higher than the national standard. The average PM 10 value was mg/ m 3, meeting the national standard. This situation, again, was much better than the background level of mg/m 3 shown in Table For NOx, the maximum measured daily value was only mg/m 3 ; all the values were less than the national standard value of 0.08 mg/m In summary, given the high background pollutant levels in ambient air in Baiyin, we can conclude that the air quality of the areas near the construction sites were well managed during the reporting area. 2. Noise Monitoring 38. Noise was monitored around the construction sites from July to December The same 12 monitoring locations for air quality monitoring were selected for noise monitoring (Figures 3 and 4). The noise monitoring was conducted once every quarter for two consecutive days at each location, and the equivalent continuous A-weighted sound pressure level (Leq) was sampled once during day-time (from 6:00 to 22:00) and once at night (from 22:00 to 6:00). 39. All monitoring locations were located in the category II sound environmental functional area, where the national upper noise limits for daytime and night are 60 db(a) and 50 db(a), respectively. The noise monitoring results, as summarized in Table 6, showed that the maximum noise monitoring result in daytime is 54.9 db(a), lower than the national limit of 60 db(a), and the maximum noise monitoring result at night is 44.9 db(a), lower than the national limit of 50 db(a). Therefore, the noise control of this subproject fully complied with the national requirement during the reporting period. 17

Mitigation Measures Implemented and Compliance 40. Based on the reports from the PIAs and on-site supervision companies, mitigation measures for environmental protection taken by the contractors as well as compliance with safety and environmental regulations are summarized below. 1. Dust Suppression 41. The contractor implemented dust control measures including spraying water to suppress dust at the construction site. Particularly, in dry and windy conditions, more water was sprayed. Construction materials without packages were placed in a transient warehouse or covered to avoid fugitive dust. 2. Noise Control 42. According to the mitigation plans, the construction time was properly planned and no construction work was conducted at night. Construction equipment with low noise level was selected during the construction period, and the construction equipment was located as far as possible from sensitive areas. 3. Wastewater Control 43. Wastewater generated from the construction sites was discharged into municipal sewers for treatment to avoid secondary pollution. 18

24 4. Solid Waste 44. The soil from the pipe trenching was used and timely transported away. Construction wastes and domestic wastes produced during the construction period were placed at the designated site and disposed to the authorized solid waste site. 5. Compliance of Safety or Environmental Standards 45. No violations of safety or environmental standards was reported during the reporting period except some high TSP and PM 10 concentrations identified above. F. Issues and Recommendations 46. The air quality monitoring results under the Baiyin District Road Improvements Subproject indicated that most TSP and some PM 10 data exceeded the national standards. Based on the background monitoring data, high levels of TSP and PM 10 are often recorded in Baiyin area. Compared with the background figures, the monitored data around the construction sites are lower than other parts of Beiyin. This indicates that the mitigation measures implemented according to the EMP are effective and minimized the project impact to the local air quality. The relevant mitigation measure could be further strengthened in the future, especially increasing the frequency of water sprays during windy days. 19

25 IV. PINGCHUAN DISTRICT ROAD IMPROVEMENTS SUBPROJECT A. Scope of the Subproject 47. The scope of this subproject includes (i) constructing six roads of 12.6 km; (ii) installing the related sewage pipelines, storm-water pipelines and water supply pipelines; (iii) rehabilitating one existing road with a total length of 3.5 km; and (iv) building three new step river bridges and seven culverts. B. Subproject Progress 48. This subproject has two packages and both are for civil works. The construction activities under the both contracts have been substantially completed. Specifically, three roads of Changzheng East, Guangchang and Kaifa have been completed and opened to traffic. Other roads were still under construction and are expected to be completed by May The three bridges have been completed and passed the bearing capacity test. 49. The total planned investment for the Pingchuan subproject was CNY million, of which the construction investment was CNY million. By the end of 2012, the completed construction investment was CNY million, which accounts for about 88.35% of the total. C. Environmental Management Office 50. The Pingchuan District Government established an environmental management office according to the requirements of the EMP and appointed Mr. Wang Lianzhong to be responsible for the environmental management of this subproject. D. Environmental Monitoring 1. Air Quality Monitoring 51. Seven air quality monitoring locations downwind from the construction site of the subproject were selected as the monitoring stations. TSP, PM 10, and NO x were monitored once for three consecutive days in October The monitoring locations are shown in Figure 5. The results of the air quality monitoring is included in Table 7. 20

27 Table 7: Air Quality Monitoring Results for Pingchuan District Road Improvements (mg/m 3 ) Sample Sample ID Date TSP PM Station 10 NO Source: Baiyin EPB As shown in Table 7, only one TSP value of mg/m 3 was slightly higher than the national limit of 0.30 mg/m 3. The non-compliance rate was approximately 4.8%. For both PM 10 and NO 2, all monitored data were far below the national standards of 0.15 mg/m 3 and 0.08 mg/m 3, respectively. Given the high background values as previously mentioned, it can be concluded that the mitigation measures implemented according to the EMP contributed to the improvement. 2. Noise Monitoring 53. Noise levels around the construction site were monitored once every quarter, specifically in August and October The same monitoring locations for air quality monitoring were selected, as shown in Figure 5. The sample collection period lasted for two consecutive days, and the equivalent continuous A-weighted sound pressure level (Leq) was collected during daytime (from 6:00~22:00) and at night (from 22:00~6:00). 22

28 54. The applicable noise standards for daytime and night time are 60 db(a) and 50 db(a), respectively. The noise monitoring results, summarized in Table 8, showed that the maximum noise values in daytime and at night were 57.5 db(a) and 44.7 db(a), respectively; both were lower than the national limits, indicating the noise mitigation measures were well implemented.

Mitigation Measures Implemented and Compliance 1. Dust Suppression 55. The contractor implemented the required dust control measures, including implementing the dust suppression program, and spraying water to suppress dust. It was reported and observed that the water sprays were adequately applied. 2. Noise Control 56. The construction time was properly planned, and night work was avoided. Construction equipment with low noise was selected and used during the construction period. Construction equipment was appropriately located to minimize noise levels. 3. Wastewater Control and Solid Waste Management 57. Wastewater generated by construction activities was collected and discharged into municipal sewers to avoid secondary pollution. The soil from the earth work was covered and backfilled regularly. Construction waste during construction was transported out of the area shortly after the construction. 4. Violation of Safety or Environmental Standards 58. Other than the one case of slight TSP non-compliance identified above, no violations of safety or environmental standards were reported during the reporting period. 23

29 F. Issues and Recommendations The impact of air pollution and noise was well mitigated under the Pingchuan District Road Improvements Subproject, with nearly all the monitoring results meeting the national standards. This indicates that the mitigation measures implemented according to the EMP contributed to improvement. These mitigation measures should be maintained in the future. 24

30 V. BAIYIN DISTRICT HEATING SERVICES SUBPROJECT A. Scope of the Subproject 59. The scope of this subproject includes expanding the district heating service area in Baiyin District by 3.2 million m 2 through (i) building a new heating source plant with 4x58 megawatts (MW) capacity, (ii) laying down 12.6 km of heat transmission pipelines, and (iii) installing 29 heat exchange stations for connection with the community heat distribution systems.

Minyue District Heating Company appointed Mr. Zeng Xianlong to be responsible for the environmental management of this subproject. D. Environmental Monitoring 1. Air Quality Monitoring 63. Three air quality monitoring stations around the heat source plant were set up and their locations are shown in Figure 6. The monitoring data on TSP was collected twice each month during the heating season, November and December in 2012, and each monitoring period lasted for two days. The results of air quality monitoring are shown in Table 9. 25

32 64. From Table 9, we can see that the minimum daily value for TSP was mg/m 3, while the maximum daily value was mg/m 3. All of the recorded TSP values were higher than the national standard value of mg/m 3. The average value of mg/m 3 was 40% higher than the national standard. 65. The environment monitoring equipment under the subproject just passed the acceptance test in late December The emissions of PM of the boiler plant monitored by the Baiyin EPB and the monitoring equipment on the date of 19 and 20 December 2012 are listed in Table 10 below. Nearly all the emission data were lower than the national standard 2 of 250 mg/m 3, indicating the emission of the newly built boiler met the relevant standard. Since there is no construction activity at the plan and the boiler emissions are through a tall stack, the non-compliance of TSP of the locations around the boiler plant was not caused by the boiler plant. Its more related to the high level background pollution as previously mentioned for the other subprojects.

Noise was monitored in the areas affected by the subproject around the site boundary. Four monitoring locations round the boiler plant were selected as shown in Figure 6. The monitoring lasted for two consecutive days during the heating season. The applicable standard used for noise monitoring and compliance evaluation is the Standard of Noise at Boundary of Industrial Enterprises (GB ). 67. The noise monitoring results, summarized in Table 11, showed that all the recorded results for noise were in compliance with the national standards of 70 db during daytime and 55 db at night. 2 Standard for Boiler Air Pollutant Emissions, GB

Demolishing Small Boilers 68. During the reporting period, 4 more small boiler houses with 4 small boilers were decommissioned. In total, 38 small boiler houses with 64 small boilers were closed under the subproject. It s estimated that the boiler monthly coal consumption was reduced from 8.5 kg/m 2 to 7.5 kg/m 2 ; the monthly electricity consumption was reduced from 0.9 kwh//m 2 to 0.8 kwh//m 2 ; the monthly water consumption was reduced from 30 kg//m 2 to 25 kg//m 2. E. Mitigation Measures Implemented and Compliance 1. Noise Control 69. The construction of the heat source plant had been completed. Noise mitigation measures were implemented for the fans and pumps in the heat source plant during the normal operation of the plant. 2. Wastewater Control and Solid Waste Management 70. Wastewater was discharged into municipal sewers. The slag and ash produced from the boiler were sold to a construction company that uses it as a raw building material. 3. Compliance of Safety or Environmental Standards 71. Except TSP non-compliance, no violations of safety or other environmental standards were observed or reported from the heat source plant during the reporting period. F. Issues and Recommendations 72. Under the Baiyin District Heating Services Subproject, the monitoring shows that all TSP values exceeded the national standard. This was mainly due to the high background TSP values instead of the boiler plant s emissions, which were in compliance with the relevant national standard for boiler emissions. 73. The continuous emission monitoring (CEM) system has passed the checking tests and accepted by the Baiyin EPB and it will can start normal operation since It will help make real-time monitoring for future emission control. 28

34 VI. CONCLUSIONS 74. During the construction period in the second half of 2012, the EMPs for the four subprojects were adequately implemented by the contractors in accordance with the national and local environmental codes and regulations and the requirements of the EIAs. The adverse environmental impacts arising from the construction period were minimized by implementing relevant mitigation measures according to the EMP. In general, the subprojects were constructed in accordance with the national and local environmental protection procedures and the requirements of the EIAs. 75. The monitoring results indicated that the TSP emission levels in many monitoring locations exceeded the national standards for some subprojects, such as Baiyin District Heating Services Subproject and Baiyin District Road Improvements Subproject. Such non-compliance, however, is much less serious compared with the high background values in Baiyin City, which indicated that the mitigation measures implemented for all subprojects in accordance with the EMP contributed to the reduced impact. In addition, all the four subprojects achieved satisfactory noise control effect, without any noise monitoring value exceeding the relevant standards. 76. The CEM system under the Baiyin District Heating Service Subproject passed the acceptance testing in late December It will start operation since January 2013 to collect and analyze SO 2, NO x and TSP monitoring data during the heating season. 29
