I. INTRODUCTION

1. Based on 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,

ADB’s Environmental Policy (2002) and the Environmental Impact Assessment reports

(EIAs); (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 EIAs; and (iii) the

implementation of the environmental management plan (EMP) and any violation of safety or

environmental standards, if any, be regularly reported to ADB.

2. Environmental specialists from the consultant firm and the Baiyin PMO visited project

sites during this reporting period. During their visits, in depth discussions were made with the

PIAs during which particular attention was focused on their responsibilities for environmental

monitoring and preparing monitoring reports. The Baiyin PMO has contracted with Baiyin

Municipal Environmental Monitoring Station of Baiyin Environmental Protection Bureau to

monitor the environmental conditions in accordance with the EIAs.

3. The Gansu Baiyin Urban Development 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

PMO and PIAs in completing the environmental monitoring requirements and preparing

monitoring reports.

4. This semi-annual environmental report describes the implementation of the

environmental monitoring and mitigation measures recommended in the EIAs, analyzes

environmental data collected from related subprojects during the period of July through

December 2011, and provides recommendations on issues identified.

5. Specifically, this environmental monitoring report covers the following areas: (i)

documentation review and compliance assessment with applicable environmental

regulations, (ii) environmental management institutional structure and responsibilities, (iii)

mitigation measures undertaken to minimize adverse environmental impacts arising from the

construction of each subproject, (iv) environmental monitoring results and analyses, and (v)

conclusions and recommendations.


A. Basis of the Report

6. This semi-annual environmental 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 Environmental Protection Bureau; EIAs for all

subprojects;

Environmental supervision reports provided by each PIA;

EMPs submitted to ADB;

Project Agreement; and

Relevant environmental laws and regulations.

B. 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 PIA’s designated staff from the site management team plays an

important role in environmental monitoring and supervision. The responsibilities of the staff

includes 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 during the construction priod

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 has

designated Ms. Zhang Qiong, with an environmental engineering background, to serve as an

environmental officer for this Project. The PMO, with the assistance from consultants, is

responsible for compiling the semi-annual environmental monitoring reports. Specific

responsibilities of the PIAs, contractors, local environmental monitoring station, and

construction supervision companies have been communicated with relevant parties with

training provided and they summarized as follows:

PIAs:

Develop 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;


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 for environmental meetings as necessary.

Local Environmental Monitoring Station:

Prepare environmental monitoring plan;

Conduct environmental monitoring; and

Develop environmental monitoring reports based on the sampled data.

Supervision Companies (during construction period):

Supervise implementation of environment protection measures;

Perform environmental management responsibilities;

II. SOUTHERN BAIYIN INFRASTRUCTURE SUBPROJECT

A. Scope of Subproject

10. Under this component, the Project will develop, as part of the Southern Baiyin

Industrial Zone (SBIZ), 4.7 km2 of industrial land with basic public infrastructure, including

18.5 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 PMO and the IA, BHTIP Management Commission reported that scope of this

component needs to be optimized 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 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 scope will

resulted in reduction of 6.5 km road construction works for four roads: Nansanhuan Road,

Nansihuan Road, Nanjingerlu Road and Nanweisanlu Road, and the industrial land area to

be developed will be reduced to 4.7 km2. The proposed change was approved by Baiyin

Municipal Development and Reform Commission (Baiyin DRC) in April 2010.

B. Subproject Progress

12. There are three procurement packages (2 NCB and 1 ICB) under the ADB loan. They

are all civil work packages and comprised as follows: C01 - Earth Work, C02 - Southern

Baiyin Infrastructure #1, and C03 - Southern Baiyin Infrastructure #2.

13. The planned total investment for Southern Baiyin Infrastructure Component was CNY

374,959,400 million of which the engineering construction investment was CNY 235,985,500

million. By the end of 2011, the contract amount was completed by CNY 288,132,700, of

which construction investment was completed by CNY 248,812,700. From January to the

end 2011, the contract amount was completed by CNY 56,832,700, which accounts for

53.84% of CNY105.55 million planned investment in 2011.

C. Environmental Management Office

14. The environmental management office (EMO) is required to be established to

monitor the implementation of the EMP. The Baiyin High-tech Industrial Park Management

Committee (BHIPMC) has appointed Mr. Zeng Chengfu to be responsible for the

environmental management of this subproject during the construction period.

1. Air Quality Monitoring

15. One air quality monitoring location downwind from the construction site of the

subproject was selected as the monitoring station and it is located 200 meters from the site


boundary. Both TSP and PM10 were monitored for two days each month from July to

December 2011, and two samples were taken each day. The locations of the monitoring

sites are shown in Figure 1.

16. The results of the air quality monitoring, as seen in Table 1, showed that the

minimum value for TSP was 0.178 mg/m3, and the maximum value was 0.418 mg/m3. Eight

out of 24 samples (or approximately 33%) have the daily values for TSP higher than the

national limit of 0.30 mg/m3. The minimum value for PM10 was 0.075 mg/m3, and the

maximum daily value was 0.166 mg/m3. One of the 24 PM10 samples (4.2%) was higher than

the national limit of 0.15 mg/m3. All high TSP and PM10 concentrations were recorded in

November and December 2011, which were very dry months. Based on the local

precipitation data as shown in Table 2, there was very little precipitation in November and no

precipitation in December.

17. The background TSP concentrations in Baiyin area were also collected and are

shown in Table 3. As it can be seen from this table, the monthly average background TSP

concentrations in December 2011 were over 0.5 mg/m3, which is much higher than the

national standard and also higher than the concentrations near the construction site.

18. The background PM10 concentrations in Baiyin area were also collected and are

shown in Table 4. As it can be seen from this table, the monthly average background PM10

concentrations in November and December 2011 were 0.158 mg/m3 and 0.224 mg/m3,

respectively, and they all exceeded the national ambient air quality standard for PM10.

19. Based on above analysis, it is reasonable to conclude that the high TSP and PM10

concentrations are not likely caused by the project activities. It’s also observed that the

average TSP and PM10 values are lower than the values in the previous semi-annual

environmental monitoring report. The results indicated that the implemented mitigation

measures contribute to improvement.

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 also shown

in Figure 1. The monitoring lasted for one day each month from July to December 2011, and

the equivalent continuous A-weighted sound pressure level (Leq) was tested during daytime

from 6:00 to 22:00 and during the night from 22:00 to 6:00.

monitoring locations were located is the 4th category sound environmental functional area,

where upper noise limits for daytime and night are 70 dB (A) and 55 dB (A), respectively.

22. The noise monitoring results are summarized in Table 5 and showed that the

recorded noise results were in compliance with the standards of 70 dB (A) in daytime and 55

dB (A) at night based on the functional category.

23. The monitoring results are lower than the values in previous semi-annual

environmental monitoring report, which indicates that the implemented mitigation measures

contribute to improvement of noise environment.

3. Wastewater Monitoring

24. Since no wastewater is generated from this construction site in the second half of

2011, monitoring data concerning wastewater discharged into the municipal sewers was not

collected during the reporting period.

4. Solid Waste

25. The subproject earth work is conducted during the construction period. Waste soil

excavated during earth work was transported to a designated place and disposed properly.

E. Mitigation Measures Implemented and Compliance Assessment

1. Dust Suppression

26. The Contractor was responsible to implement dust control measures, including

developing a dust suppression program for water spraying, and daily water spraying on the

construction site to suppress fugitive dusts. Particularly, in dry and windy conditions, water

spraying was conducted more frequently. Construction materials were covered to avoid

fugitive dust emissions.


2. Noise Control

27. Construction time was properly planed from 7:00 to 18:00, and night work was

forbidden. The construction sites are far from the sensitive points, such as residential area,

school and hospital etc. Construction equipment with low noise was selected to be used

during the construction period, and the construction equipment was located as close to the

center of the site as possible. Due to the mitigation measures, the noise monitoring results

indicated that noise levels are in compliance with the national standards in China.

3. Wastewater Control

28. No wastewater is generated from this construction site in the second half of 2011.

Once the wastewater is generated from the site, which will be discharged to the municipal

sewer system for further treatment to avoid secondary pollution. Especially the domestic

wastewater from construction sites of procurement package C02 and C01 will be all

discharged to the septic-tank.

4. Solid Waste

29. Truck cleaning facilities were located at the entrance and exit of the construction site

to control fugitive soils caused by truck outside the construction area. The soil from the earth

work was appropriately used and timely transported out when necessary. A guard net was

employed during transportation to avoid fugitive dust. Water spraying was applied following

the backfill. The solid waste was collected, and which was placed on the designated area.

5. Compliance with Safety or Environmental Standards

30. No violations of safety or environmental standards was reported during the reporting

period besides the TSP and PM10 violations identified above.

F. Issues and Recommendations

31. A few monitored TSP and PM10 results exceeded the national standards. However,

based on the background monitoring data, high levels of TSP and PM10 are recorded in

Baiyin area. The TSP and PM10 monitoring results are better than the values in the previous

semi-annual environmental monitoring report. Even though the high TSP and PM10

concentrations were not likely caused by the project activities, it is still recommended that

more air pollution mitigation measures be taken according the EMP to minimize fugitive dust

emissions from the project.


III. BAIYIN DISTRICT ROAD IMPROVEMENTS

A. Scope of the Subproject

32. Under this component, the Project will (i) construct nine new roads with 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 component

will also (i) build 14 bridges/culverts and (ii) rehabilitate and widen three existing roads with a

total length of 6.1 km.

33. There was a change of scope of this subproject in 2011. The specific changes in

subproject scope are as follows: (i) 3.2 km road sections from East Binhe Road and West

Binhe Road as per the reprioritized urban transport development plan has been removed.

The removed road sections will be constructed at later stage. Baiyin DRC approved the

proposed scope change in March 2011; (ii) Extension of rehabilitation works of Fangzhi

Road of 451 m to ensure the smooth and constant traffic along the whole road. ADB’s review

mission in July 2010 visited the site and noted that that the proposed extension works would

be along the existing Fangzhi Road and will not involve any resettlement. Environmental

impact assessment was performed and it was concluded that there is no substantial negative

environment impact. Baiyin DRC approved the proposed extension in January 2011; and (iii)

Add additional rehabilitation and maintenance works for six primary or secondary roads in

Baiyin District.


34. There are three procurement packages under the ADB loan for this subproject. Two

of them are civil works packages and one is the equipment procurement package.

35. The planned total investment for this subproject was CNY 338,271,300, of which the

construction investment was CNY 235,985,500. Civil works contract C05 would need to be

amended to reflect the extension of Fangzhi Road rehabilitation works. The contract amount

will be increased from CNY91, 670,400 to CNY94, 690,437 (3% of original contract price).

The contract was extended to 30 June 2012. By the end of 2011, CNY 198,250,000 of

contract amount was completed, of which CNY 92,796,800 of construction investment was

completed. From January to the end 2011, the contract amount was completed by CNY 45

million, which accounts for 35.79% of CNY 125,728,600 of investment planned in 2011.


36. The Baiyin City Construction Bureau (BCCB) has appointed Mr. Wang Dongye as the

responsible manager for the environmental management of this subproject as required by

the EMP.


D. Environmental Monitoring


37. Three air quality monitoring locations downwind from the construction site of the

subproject were selected as monitoring stations and they were located approximately 200

meters from the site boundary. TSP, PM10, and NOx were monitored for three days in

November. The locations of the monitoring stations are shown in Figure 2.

38. The results from the air quality monitoring, as shown in Table 6 below, indicates that

the maximum value of TSP was 0.421 mg/m3. Eight out of nine samples (or approximately

89%) have the daily values for TSP higher than the national limit of 0.30 mg/m3. For PM10,

the maximum daily value was 0.147 mg/m3, which is below the national standard of 0.15

mg/m3. For NOx, the maximum daily value was 0.028 mg/m3, and all of the values were

less than the standard value of 0.08 mg/m3. Compare to the previous data from last

semi-annual environmental report, average values of TSP, PM10 and NOx in three locations

are higher.

39. The high TSP monitoring results are mainly due to three factors: dry winter season,

high background concentration and inadequate implementation of the TSP mitigation

measures. As explained earlier, the background TSP concentrations in Baiyin area, as

shown in Table 3, were very high in winter months. As it can be seen from Table 3, the

monthly average background TSP concentrations in December 2011 were over 0.5 mg/m3,

which is much higher than the national standard.1

2. Noise Monitoring

40. Noise was monitored around the construction sites in July and November 2011. The

monitoring locations are also shown in Figure 2. The noise monitoring at each location

lasted for two days, and the equivalent continuous A-weighted sound pressure level (Leq)

was sampled during day-time from 6:00 to 22:00 and at night from 22:00 to 6:00 of each day.


Standard of Noise at Boundary of Industrial Enterprises, GB 12348-2008. All monitoring

locations were located in the 1st category sound environmental functional area, where the

upper noise limits for daytime and night are 55 dB (A) and 45 dB (A), respectively. The noise

monitoring results, summarized in Table 7 showed that the recorded noise results were in

compliance with the standards of 55 dB (A) in daytime and 45 dB (A) at night based on the

3. Wastewater Monitoring

42. No monitoring data concerning wastewater discharged into the municipal sewer were

collected during the reporting period.

4. Solid Waste

43. Construction wastes and domestic wastes were produced during the construction

period and they were placed at the designated site and disposed to the authorized solid

waste site.

E. Mitigation Measures Implemented and Compliance

44. Based on the reports from the PIAs and on-site supervision companies, mitigation

measures for environmental protection taken by contractors as well as compliance with

safety and environmental regulations are summarized below.

1. Dust Suppression

45. The contractor implemented dust control measures including spraying water to

suppress dust at the construction site. Particularly, in dry and windy conditions, more water

must be sprayed. Construction materials without packages were placed in a transient

warehouse or covered to avoid fugitive dust emissions.

2. Noise Control

46. According to mitigation plans, construction time must be properly planned and night

work is strictly forbidden. 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. However, some high noise levels were measured and this is primarily due to

other noise sources not related to the road construction activities.

3. Wastewater Control

47. Wastewater generated from the construction sites was discharged into municipal

sewers for treatment to avoid secondary pollution.

4. Solid Waste

48. The truck clearing facilities were placed at the site to minimize fugitive dust

emissions. The soil from the pipe trenching was used and timely transported away. Other

construction waste was also transported out of the construction site.

5. Compliance of Safety or Environmental Standards

49. A slight high noise levels were observed. No other violations of safety or

environmental standards were observed and reported during the reporting period.


50. The monitored TSP and PM10 results indicated that some values exceeded the

national standards, and the monitoring results in three locations were also higher than the

previous semi-annual environmental report. It is recommended the IA and contractor

should take more air pollution mitigation measures according the EMP to ensure comply with

the national standards. More specifically, increasing the frequency of water sprays will help

reducing the TSC and PM10 levels. However, based on the background monitoring data, high

levels of TSP and PM10 are often recorded in Baiyin area, especially during winter dry

season. Due to dry climate conditions, baselines levels sometimes exceed the national

standards for TSP and PM10.


IV. PINGCHUAN DISTRICT ROAD IMPROVEMENTS SUBPROJECT


51. Under this component, the Project will construct 12.6 km roads; and the related

sewage pipelines, storm-water pipelines and water supply pipelines; rehabilitate existing one

road with the total length of 3.5 km; (ii) build three new Step River Bridges, and 7 culverts.


52. This subproject has two packages and both are for civil works. Both contracts have

been awarded and construction activities have substantially completed.

53. The total planned investment for Pingchuan District Component was CNY

210,005,000, of which the construction investment was CNY 160,150,800. By the end of

2011, the investment was completed by CNY 175.1 million accumulatively, of which

construction investment was completed by CNY 138.5 million. From January to the end

2011, the contract amount was completed by CNY 19.1 million, which accounts for 37.58%

of CNY 50,821,000 of investment planned in 2011.


54. The Pingchuan District Government (PDG) has 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.



55. Nine air quality monitoring locations downwind from the construction site of the

subproject were selected as monitoring stations. TSP, PM10, and NOx were monitored for

three days in November 2011. The monitoring locations are shown in Figure 3.

56. The results of the air quality monitoring in November 2011, as seen in Table 8,

showed that the maximum value of TSP was 0.487 mg/m3. All 27 values for TSP were higher

than the national standard of 0.30 mg/m3. For PM10, the maximum daily value was 0.203

mg/m3. Nine values for PM10 are higher than the national standard of 0.15 mg/m3. For NOx,

the maximum daily value was 0.030 mg/m3, and all of the values were less than the national

standard value of 0.08 mg/m3. And the monitoring results in nine locations are higher than

the previous data from the last semi-annual environmental report, especially TSP.

57. Even though the background TSP and PM10 concentrations are high in Baiyin area in

winter months due to dry climate, the monitoring results indicate that the dust control

mitigation measures as specified in the EMP are not properly implemented. The PIA must

work closely with the construction contractors to ensure that the mitigation measures are

adequately implemented.

2. Noise Monitoring

58. Noise levels around the construction site were monitored in September and

November 2011. The monitoring locations are shown in Figure 3 as well. The sample

collection period lasted for two days, and the equivalent continuous A-weighted sound

pressure level (Leq) was collected during daytime from 6:00 to 22:00 and at night from 22:00

to 6:00 of each day.


Standard of Noise at Boundary of Industrial Enterprises, GB 12348-2008. The area where #1

to #4 monitoring locations were located is the 1st category sound environmental functional

area, where noise upper limits for daytime and night are 55 dB (A) and 45 dB (A),

respectively.

60. The noise monitoring results are shown in Table 9 and they showed that five out of

36 recorded daytime noise levels exceeded the standard values of 55 dB(A) slightly.

However, the noise levels are lower than the values for the last semi-annual environmental

report. One of 36 recorded values at night exceeded the standard of 45 dB (A).

3. Wastewater and Solid Waste

61. No monitoring data concerning wastewater discharged into the municipal sewers was

provided during the reporting period. Construction waste and domestic waste were produced

during the construction period and they were placed at the designated site and disposed of

properly.


1. Dust Suppression

62. The Contractor was responsible to implement 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 applied. Based on the monitoring results,

it indicates that the mitigation measures were not fully implemented.

Figure 4: Water Sprays for Fugitive Dust Control


2. Noise Control

63. The construction time was properly planed, and night work was forbidden.

Construction equipment with low noise was selected and used during the construction

period. Construction equipment should be appropriately located to minimize noise levels.

Mitigation measurements should be enhanced to control noise levels both during daytime

and at night since some noise measurement data exceeded the National Standard.

3. Wastewater Control and Solid Waste Management

64. 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 bridge construction was transported out

of the area shortly.

4. Violation of Safety or Environmental Standards

65. Other than the high levels of TSP, PM10 and noise levels identified above, no other

violations of safety or environmental standards was reported during the reporting period.


66. The monitored TSP and PM10 exceeded the national standards, and the monitoring

results in nine locations are also higher than the data from last semi-annual environmental

report, especially TSP. Therefore, it’s recommended more frequent water sprays must be

applied to mitigate the TSP and PM10 emissions.


V. Baiyin District Heating Services Subproject


67. The scope of this subproject includes expanding the district heating service area in

Baiyin District by 3.2 million m2 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.


68. The construction of the heating resource plant has been completed. All four boilers

have been installed at the boiler plant. The four boilers were in operation during the heating

season in 2011. As of the end of 2011, 29,160 m of heating pipe networks have been laid

and 14 heating exchange stations have been installed and put into operation. In addition, 60

small coal-fired boilers from 34 small boiler stations have been removed from service and

the area connected to these boilers are now served by the central heating plant.

69. An online continuous emission monitor (CEM) system is required per the approved

environmental impact assessment report by the municipal environmental authority and the

EMP. However, such a system has yet to be installed. To meet this requirement, Baiyin PMO

and MDHC requested to add a new package into the procurement plan for procuring and

installing a CEM system in the heating source plant. This system will monitor the emission of

flue dust, SO2 and NOx, and will be connected to the monitoring system of Baiyin

Environmental Protection Bureau. Cost of this package is estimated at CNY1.28 million.

70. By the end of 2011, the investment was completed by CNY 157.44 million

accumulatively, of which construction investment was completed by CNY 145.94 million.


71. An EMO has been established by the IA to monitor the implementation of the EMP.

Minyue District Heating Company (MDHC) has appointed Mr. Zeng Xianlong to be

responsible for the environmental management of this subproject.



72. Three air quality monitoring stations downwind of the heat source plant were set up

and their locations are shown in Figure 5. TSP was monitored every month from July

through December 2011. The monitoring data was collected two times each month, and

each monitoring period lasted for two days.

■ Air monitoring spots

73. The results of air quality monitoring, shown in Table 10, indicate that the minimum

daily value for TSP was 0.156 mg/m3, and the maximum daily value of 0.410 mg/m3. 20

values of 72 recorded values (27.8%) for TSP were higher than the national standard value

of 0.30 mg/m3. TSP values of November and December were higher than other months.

Since there was no construction activities in these two months, this is mainly due to high

background TSP concentrations during dry winter season as explained earlier and the start

of a new heating season.

2. Noise Monitoring

74. Noise was monitored in the areas affected by the subproject around the site

boundary during the construction period. The monitoring locations are also shown in Figure

5. The monitoring lasted for two days, and the equivalent continuous A-weighted sound

pressure level (Leq) was measured during daytime from 6:00 to 22:00 and at night from

22:00 to 6:00 of each day. The applicable standard used for noise monitoring and

compliance evaluation is the Standard of Noise at Boundary of Industrial Enterprises, GB

12348-2008.

75. The noise monitoring results, summarized in Table 11, showed that the recorded

results for noise were in compliance with the national standards of 70dB during daytime and

55 dB during night. And the noise monitoring results were lower than the results collected

from last semi-annual environmental report.

3. Wastewater Monitoring and Solid Waste Management

76. No monitoring data concerning wastewater discharged into the municipal sewers was

provided during the reporting period. Construction wastes and domestic wastes were placed

at the designated site and disposed of properly.

4. Demolishing Small Boilers

77. No additional small boilers were closed during this reporting period. So far 31 boiler

houses with a total 46 small boilers have been decommissioned.


1. Dust Suppression

78. The coal pile at the heat source plant is supposed to be cover to avoid fugitive dust

emissions. However, it was not covered during the site visits. The dust collector in the heat

source plant was put into service for reducing the dust emission.

2. Noise Control

79. Since the construction of the heat source plant has been completed. Noise mitigation

measures have been taken for the fans and pumps in the heat source plant during the

normal operation of the plant.

3. Wastewater Control and Solid Waste Management

80. Wastewater was discharged into municipal sewers to avoid secondary pollution.

Wastewater of the heat source plant was treated and then discharged. The slag and ash

produced from the boiler were sold to a construction company that use it as a raw building

material.


4. Compliance of Safety or Environmental Standards

81. Other than the high TSP levels identified above, no other violations of safety or

environmental standards were reported during the reporting period.


82. TSP, SO2, NOx, and PM10 emissions are required to be monitored at the heat source

plant. Stack emission testing and a CEM system should be installed in 2012.

83. The environmental management of the coal yard needs to be further enhanced. The

coal should be covered to prevent fugitive dust emissions.


VI. CONCLUSIONS

84. The EMPs for the four subprojects were generally implemented during the

construction period in 2011. In accordance with the national and local environmental codes

and regulations, and the requirements of the PIAs, contractors carried out environmental

protection and mitigation measures. The adverse environmental impacts arising from the

construction period were minimized by implementing relevant mitigation measures. In

general, the subprojects were constructed in accordance with the national and local

environmental protection procedures, and the requirements of the EIAs. The noise

monitoring results of the four subprojects were better than the those in last semi-annual

environmental report.

85. However, the monitoring results indicated that TSP emission levels November and

December in many monitoring locations exceeded the national standards for some

subprojects, such as Baiyin District Road improvement Subproject and Pingchuan District

Road Improvement Subproject. The data in some monitoring locations are also higher than

the data from last semi-annual environmental report, This is partly due to the high level of

background TSP levels in Baiyin area. However, it is necessary to take further environmental

protection and mitigation measures to reduce fugitive dust emissions from the construction

sites.

86. The CEM system should be procured, installed and calibrated before the 2012

heating season starts. Environmental acceptance by the Baiyin EPA should be conducted

for the heat source plant during heating season. SO2, NOx and PM10 monitoring data should

be collected and analyzed during both heating season and non-heating season.

Desulfurization and dust removal measures must be conducted to reduce SO2 and flue dust

emission.
