I. INTRODUCTION
1.1 General Introduction
This Report is the sixth semi-annual environmental report (SAER) for the Fuzhou Environmental Improvement Project (the Project) for the period from 1 Jun to 30 Nov 2010. It is prepared by the Fuzhou Project Management Office (FPMO) with the assistance of Black & Veatch International Company (B&V). B&V has been providing project implementation consulting services to FPMO who is the Executing Agency (EA) for the Project.
ADB funded civil work contracts have progressively been awarded since Nov 2006, and construction of the first awarded contract started in Jan 2007. This Report describes the activities undertaken in the period from the beginning of Jun 2010 till end of Nov 2010 with respect to the implementation of the environmental management plans (EMPs) of the project components. This Report contains the following activities and topics: (i) the environmental institutional strengthening and capacity building; (ii) mitigation measures undertaken to minimize adverse environmental impacts arising from the construction of the Project facilities; (iii) environmental monitoring and assessment; (iv) responses to ADB’s comments on last environmental report; and (iv) conclusions and suggestions.
1.2 Description of the Project
This Project has three structural components with their original scope presented below. The project location is shown in Figure 1 . A submission to ADB proposing some changes to the project scope is currently under preparation; such changes have no material impact to the environmental management work and this SAER.
• Component A - Yangli Phase 2 Sewer Networks: to construct 253.25 km of new sewers, rehabilitate 27 km of existing sewers, and construct and upgrade 5 pumping stations; • Component B - Lianban Sewer Networks: to construct 126.83 km of new sewers, rehabilitate 76 km of existing sewers, and construct 4 pumping stations; and • Component C - Nantai Island Inland Creek Rehabilitation: to rehabilitate 12 inland creeks with a combined length of about 48km; dredge and/or excavate 3.63 million tons of earthwork; construct varying widths of stone-lined rectangular channels and 1 rubber dam; and rehabilitate 4 existing flood gates.
There is also a Capacity Building component (Component D) which is non-structural in nature to support project implementation and training of the implementing agencies (IAs). One important element in this component is institutional strengthening, capacity building, and training in environmental management. The target trainees include the FPMO and IAs as well as contractors and construction supervision companies. The purpose is to build up the capacity of these entities so that they are more capable in implementing the EMP and environmental monitoring.
The total estimated project cost was US$ 185.5 million at the appraisal stage, of which US$ 55.8 million is loaned by the Asian Development Bank (ADB) to the People’s Republic of China (PRC) and then on-lent to the Fuzhou Municipal Government (FMG). The counterpart funding of the Project is about US$ 130 million which is being provided by a combination of domestic borrowing and FMG equity.
1.3 Description of the Environment
As the capital of Fujian Province, Fuzhou is one of the important cities in Southeast China, and is the Province’s main political, economic, trade, information and cultural center. Fuzhou is located in eastern Fujian Province, adjacent to the China East Sea. Nantai Island is located south of Fuzhou at Cangshan which is one of Administration Districts of Fuzhou. As of the end 2009, the residential population of Fuzhou Municipality is 6.87 million including 2.71 million in main urban area.

The topography of Nantai Island is characterized as hilly in the northwest and middle, and broad alluvial plain in the southeast, sloping from northwest to the southeast of the island.
The Project area has a subtropical marine monsoon climate, warm and humid, with abundant precipitation mostly falling during summer. The average annual precipitation is 1,343 mm, approximately 75% of which falls during April to September accompanied by frequent typhoons. The average annual temperature is 19.6 oC. The hottest month is July, and the highest temperature over the years is 39.9 oC. The prevailing wind direction through the year is from the southeast, with the average and the highest wind speeds being 2.7 and 31.7 m/s, respectively.
Dec 2010 (2)
Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
Fuzhou has complicated waterways in the urban area. There are over 70 inland rivers including Guangming Gang, Jin’an River and Baima River, with a total length of 99.3 km in the northern bank of Min River. Other than a few rivers including Jin’an River, most of the other rivers are small and without natural sources. These inland rivers join Min River and their hydrological conditions are subjected to the influence of tide from Min River and the operations of flood gates along the rivers. Flood control is the primary function of these inland rivers. Most of these inland rivers have little natural runoff other than the wastewater discharge to them. The inland rivers in the city require flow augmentation from Min River to flush their stagnant water, typically with a total flow of about 30 m3/s.
Min River is the largest river in Fuzhou, and traverses Fuzhou from the northwest to southeast, with a total length of approximately 150 km. The main trunk of Min River was divided into the northern and southern branches at Huaian by Nantai Island. Min River has a large water flow and the annual average flow is about 1,713m 3/s, and average annual runoff flow reaches 55.1 billion m 3. Min River is the most important water source and is also the primary receiving water body for wastewater, and navigation channel for the Fuzhou urban area.
Native vegetation has been damaged by human activities, and currently secondary and planted vegetation forms a relatively simple biota structure. There are no large wild animals inhabiting within the Project area, and most of the wild animals are mice. There are two small wetlands in the eastern Nantai Island that are major bird habitat areas. There are no forests (secondary or native), nature reserves, rare or endangered species in the Project area.
The predominant industries in Fuzhou include machinery, metallurgy, electronics, light industry, food, textile, pharmaceutical and high tech. The gross domestic product (GDP) of Fuzhou in 2009 was CNY 252.428 billion, approximately CNY 36,851 per capita.

Other Reports
The environmental supervision engineers compile monthly reports on all ongoing contracts under their supervision in a timely manner, and the reports’ quality has been greatly improved after the training this year. Both FWECDC and FUVCDC prepared their environmental management reports.
IV. IMPLEMENTATION OF MITIGATION MEASURES
The EMPs have been incorporated in the contract documents by the two IAs according to ADB’s requirements. The contractors have implemented proper measures to mitigate unfavorable environmental impacts produced in construction phase. The implemented measures are generally in line with the EMPs.
4.1 Component A - Yangli Phase II Sewers
Construction activities in Component A were little in this reporting period. The contractor timely implemented proper measures to mitigate the unfavorable environmental impacts produced in sewer construction, such as slurry water from pipe jacking, solid waste from caisson and open trench excavation, and dust and noise from various construction activities. The associated Yangli WWTP Phase II Extension Work has been operational since Oct 2008 to receive wastewater collected by the completed sewers under Component A. Mitigation measures for the unfavorable environmental impacts produced in the operation phase of the WWTP such as wastewater and sludge are implemented by the operator, and water quality monitoring exercises to influent and effluent are conducted regularly by the WWTP’s laboratory. In addition, online monitoring facilities have been established in accordance with the local EPB’s requirements to ensure effluent to be continuously monitored by FMEPB. Detailed mitigation measures implemented are presented in Appendix 2a .
4.2 Component B - Lianban Sewers
In this reporting period, proper mitigation measures continued to be implemented by the contractors to mitigate unfavorable environmental impacts produced in the construction phase such as slurry water from pipe jacking, solid waste from caisson and open trench excavation, and dust and noise from various construction activities. Construction of the associated Lianban WWTP work is still ongoing, and completion is expected at end 2010 / early 2011. The WWTP contractor has implemented proper measures to mitigate unfavorable environmental impacts produced in construction phase according to the EIA requirements. With the Component B sewers being progressively completed, by end 2010 some wastewater can start to be delivered to the WWTP for treatment. Detailed mitigation measures implemented are presented in Appendix 2b.
4.3 Component C - Nantai Island Creek Rehabilitation
River construction activities under Component C such as earth excavation, bank lining and river dredging have produced some unfavorable environmental impacts including dust, noise and solid waste etc. Proper implementation of mitigation measures by the contractors has mitigated the impacts. The demolition waste was disposed of from Gaohu Village along the Yuejin River in August, no longer affecting local residents’ living environment. Detailed mitigation measures implemented are presented in Appendix 2c.

V. ENVIRONMENTAL MONITORING AND ENVIRONMENTAL QUALITY
5.1 Environmental Monitoring a. Internal Environmental Monitoring
Internal environmental monitoring at construction sites has been conducted by contractors’ qualified personnel and supervised by CSCs and reported via monthly reports. The internal monitoring results have shown that in this reporting period, mitigation measures have been implemented and environment has generally been well maintained in the Project. b. External Environmental Monitoring
FEMS under FMEPB has been engaged to undertake the external environmental monitoring (EEM) exercises involved in the Project. EEM exercises were conducted in this reporting period in terms of surface water, ambient air, noise and sludge. The EEM findings are given in Section 5.2 and more details are presented in Appendix 3 .
5.2 Environmental Quality
It is shown from the EEM results that in this reporting period:
(i) The water quality of the Yuejin River has improved compared with last year, but is still worse than Class V with organic pollutants significantly exceeding standard; (ii) The quality of the river bed sludge meets the standard and is suitable for agricultural use; (iii) The ambient air quality at the monitoring point meets the relevant standards; and (iv) The acoustic environment at the monitoring point is affected by the construction activities under the Project to a certain degree, but the major contribution should be the high level ambient background noise.
More details are presented in Appendix 3 .
VI. CONCLUSIONS AND RECOMMENDATIONS
In this reporting period, the contractors have implemented proper measures to mitigate unfavorable environmental impacts produced in construction.. The monitoring and evaluation exercise has revealed that the EMPs are generally being satisfactorily implemented, and the following conclusions can be drawn:
• The environmental management system which was established during the inception stage of the Project implementation consultancy has progressively been improved and strengthened. Under the coordination of the FPMO, all related parties have cooperated for better implementation of the EMPs and to comply with the environmental requirement of the Project Agreement.
• For the ongoing contracts, noise, dust and solid waste pollution during construction have been minimized through undertaking the relevant mitigation measures.
• The EEM data shows that the water quality of the inland creeks is still poor, but the river sludge is suitable for agricultural use. The ambient air quality meets relevant standards, however, the construction of the Project has had some impacts on the acoustic environment.

Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
APPENDIX 2: IMPLEMENTATION OF MITIGATION MEASURES IN CONSTRUCTION PHASE
2a: Implementation of Mitigation Measures in Construction Phase for Component A
Only Contract YGII-10 is under construction in this reporting period, and all the other civil contracts under Component A have been completed in the last reporting period.
1. Construction Wastewater Treatment
Wastewater generated in the construction phase of Contract YGII-10 is mainly the slurry water from pipe jacking. The slurry is settled in containers established at site for sedimentation. All of the containers are emptied daily. The settled sludge is transported by enclosed trucks to designated locations for disposal. The supernatant is reused for pipe jacking.
2. Dust and Exhaust Emission Control
Groundwater table is high at most construction sites under Contract YGII-10, so the excavated materials are typically slurries and do not create dust nuisance. Dust is created during excavation sometime in windy days, and the Contractor would spray water in a timely manner to reduce dust. Hoarding has been set up along the construction sites for closure, which helps minimize dust problems affecting the vicinity. Covering on exposed construction materials is carried out to prevent dust. Construction vehicles are covered to reduce dust, and speed control is exercised. The Contractor carries out weekly vehicular maintenance to prevent emission exceeding the standards.
3. Noise Control
Various types of construction machinery are used in construction under Contract YGII-10 including grabs, loaders, drilling machines, air compressors, water pumps, crushers, engines, trucks and so on. Their noise level normally ranges from 90 to 108 dB(A), which indicates they are all highly noisy machinery. Especially when breaking up road surfaces, the noise always creates significant impacts on the surrounding and nearby residents. Pipe jacking is adopted where appropriate in most contracts to reduce road opening. Construction section by section also reduces the intensity of noise pollution. Hoarding set up along the construction sites can work as sound barrier to screen out some construction noise. The Contractor carries out maintenance and spot checks for all construction machinery and vehicles, which helps reduce noise production. Working time was restricted from 7:30 am to 6:30 pm, and construction at lunch time and night time is avoided as much as possible.
4. Solid Waste Disposal
Pipe jacking is adopted as the key pipe laying method under Contract YGII-10; open trenching is used only in isolated cases. The solid waste generated in construction mainly includes the excavated material from open trench or caisson excavation, and slurry from pipe jacking. In general, pipe jacking reduces earth excavation. All excavated material has not been reused for backfilling but transported to landfills designated by the local solid waste management authority for disposal. The same arrangement is adopted for ,the settled sludge from slurry.
5. Ecological Impacts and Their Mitigation
A large banyan tree at the sewer construction site closed to the North-to-South Water Transfer Project was reported to the local parks and forestry management authority. The tree has been temporarily transplanted, and will be replanted at its original loaction after the sewer construction is completed.

Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
6. Historic Cultural Relics Discovery and Protection
During the reporting period, there is no report on historic cultural relics encountered at the construction sites.
7. Social Impacts and Their Mitigation
Hoarding is set up along the construction sites under Contract YGII-10 to separate the construction activities from social surroundings. With the assistance of local authorities managing the municipal water and wastewater pipelines and telecommunication and power cables, field detection is undertaken to locate the buried pipelines and cables before excavation. Some roads are temporarily occupied for pipe construction, and this has impacts on local traffic. The Contractor appoints one to two coordinators at each site for traffic diversion and direction.
8. Construction Camps Environmental Conditions
The construction camps for the 25 workers and management personnel under Contract YGII-10 are apartments rented from local residents with well-equipped facilities and good sanitation. Domestic water comes from the municipal water supply system, and wastewater generated is discharged into local sewers. Domestic refuse is collected in garbage bins and transported away by the public sanitation department.
9. Response to Emergencies
The Contractor have established a construction safety system, prepared emergency procedures, and equipped with security facilities. All these measures have been approved by the local construction management authority. Security personnel appointed at each construction site conducts frequent inspections in order to timely detect any safety risks. Supervision engineers also conduct checks to detect any violations. In early Nov 2010 they gave corrective instructions when a hoarding was found to be inadequately set up, the Contractor promptly rectified it on 14 Nov 2010.
10. Environmental Protection and Monitoring Measures Implemented in Yangli WWTP
Construction of the Yangli WWTP Phase II extension was completed in Oct 2008, and operation has since been ongoing. Water quality of the effluent for both Phase I and II can meet Class 1B of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). The domestic wastewater generated within the plant is treated in the WWTP. Dewatered sludge was transported to Hongmiaoling Sanitary Landfill Site for disposal. A well equipped laboratory has been set up in the WWTP to carry out regular sampling and testing of influent, effluent and sludge. In addition, online monitoring facilities have been established and connected to FMEPB’s network enabling the wastewater flow and concentrations of COD, NH 3-N and total phosphorus to be continuously monitored by FMEPB. Their water use comes from the municipal water supply system, the wastewater within the WWTP is treated at the WWTP, and domestic garbage is collected and transported to designated landfill site in a timely manner.
2b: Implementation of Mitigation Measures in Construction Phase for Component B
There are seven civil contracts (LG-02, 03, 04, 05, 06, 07 and 08) under construction in this reporting period.
1. Construction Wastewater Treatment
The bulk of the wastewater generated in the construction is the slurry water from pipe jacking and pipe pulling. The slurry is settled in containers, 3 in a series, for primary sedimentation, secondary sedimentation and supernatant storage. All these containers are emptied daily. The settled sludge at the bottom is then transported to designated locations for disposal, and the supernatant is reused in the pipe jacking operation. Specifically:.

LG-08: At Lianjiang South Road and Fuxia South Road, the slurry from caisson excavation and pipe jacking was settled in the sedimentation tanks, and the supernatant was reused in construction.
2. Dust and Exhaust Emission Control
Groundwater table is rather high at most construction sites, so the excavated materials are typically slurries and do not create dust nuisance. Covering of or water spraying on exposed construction materials is carried out to prevent dust, and the excavated material storage duration is minimized to reduce the impact. Hoarding has been set up along the construction sites for closure, which helps minimize dust problems affecting the vicinity. For the dust created at site during loading and unloading of dusty materials, or from earth dropping off vehicles, the Contractors would spray water in a timely manner to reduce dust. Construction vehicles for dusty material or solid waste transportation are covered to reduce dust, and speed control is exercised. For each contract:
LG-02: During pipe jacking on South Second Ring Road, dust was created from earth dropping off construction vehicles. It was reduced by timely water spraying and cleaning. LG-03 ：In the caisson construction and pipe jacking outside Lianban WWTP, dust was created from earth dropping off construction vehicles near the construction site. It was reduced by timely water spraying and cleaning. LG-04 ：There was little dust produced in construction of the pump rooms and switchboard rooms of No. 2 and No. 3 pumping stations. Hoarding has been set up around the construction sites for closure. LG-05 ：Dust was produced in open trench excavation at Fuxia Road. To reduce dust impacts, hoarding has been set up along the construction sites, and workers were deployed to timely spray water and clean the site. LG-06 ：During pipe pulling at Chaoyang Road, dust was created from earth dropped on the road. It was reduced by timely water spraying and cleaning. LG-07 ：In the caisson construction at Liuyi South Road, dust was created from earth dropping off construction vehicles. It was reduced by timely spraying water and cleaning. LG-08 ：In the caisson construction and pipe jacking at Lianjiang South Road and Fuxia Road, dust was created from earth dropping off construction vehicles. It was reduced by timely water spraying and cleaning.
3. Noise Control
Various types of construction machinery are used in construction including grabs, loaders, hoists, drilling machines, air compressors, water pumps, crushers, engines, trucks and so on. Their noise level normally ranges from 90 to 108 dB(A), which indicates they are all highly noisy machinery. Especially when breaking up road surfaces, the noise always creates significant impacts on the surrounding and nearby residents. In this reporting period, except for Contract LG-05 which involves some open trench construction, pipe jacking is adopted in all the other ongoing contracts. Construction section by section also shortens the duration of noise pollution at each section. Hoarding set up along the construction sites can work as sound barrier to screen out some construction noise. Periodic maintenance and spot check on noise emission
Dec 2010 (12 )
Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
are conducted by the contractors for all construction machinery. Working time was restricted from 7:30 am to 6:30 pm for each construction site, and construction at lunch time and night time was avoided as much as possible. Speed control is exercised on all construction vehicles.
4. Solid Waste Disposal
The solid waste generated in construction mainly includes the excavated material from open trench or caisson excavation, slurry from pipe jacking or pipe pulling, and small amounts of other construction wastes. In general, pipe jacking reduces earth excavation. All excavated material has not been reused for backfilling but transported to landfills designated by the local solid waste management authority for disposal as excess excavated material. The slurry sediments and other construction wastes are sent to designated landfill. Construction vehicles are covered in transportation to prevent littering and any earth dropping off vehicles is timely cleared. On specific contracts:
LG-02: At the South Second Ring Road, after the slurry from pipe jacking was settled in the sedimentation tanks, the settled sludge was transported to landfills and the dropped earth was timely cleared. LG-03: At the inlet of Lianban WWTP, after the slurry from caisson excavation and pipe jacking was dried on site, the dry material was transported off site for disposal and the earth dropping off vehicles is timely cleared. LG-04: Only small amounts of construction wastes were produced in the construction of the pump rooms and switchboard rooms of the pumping stations. They were transported to landfills. LG-05: At Fuxia Road, after the slurry from pipe jacking was settled in the sedimentation tanks established at site, and the settled sludge was transported to landfills. Any earth dropping off vehicles is timely cleared. LG-06: At Chaoyang Road, after the slurry from pipe pulling was dried on site, the dry material was transported off site for disposa. And any earth dropping off vehicles is timely cleared. LG-07: The earth excavated from caisson construction at Liuyi South Road has been transported to designated site for disposal. Any earth dropping off vehicles is timely cleared. LG-08: The earth excavated from open trench and caisson excavation at Lianjiang South Road and Fuxia South Road was transported to designated site for disposal. Settled sludge from caisson excavation and pipe jacking was transported to landfills.
5. Ecological Impacts and their Mitigation
The use of pipe jacking and pipe pulling has reduced ground subsidence. In order to prevent soil erosion, hoarding was set up along the construction sites or retaining walls were built up to block any runoff. No excavation is allowed to be carried out on rainy days, and all solid waste generated during construction is timely transported off site to prevent stock piling at site for too long a period. After the construction is completed, the roads are reinstated and cleaned in a timely manner. All these mitigation measures have contributed to soil erosion control and urban ecological environment protection.
6. Historic Cultural Relic Discovery and Protection
To-date there is no report on historic cultural relics and old trees encountered at the construction sites.
7. Social Impacts and their Mitigation
Pipe construction would bring certain inconvenience to local traffic, residents, and public facilities etc. In order to minimize the negative impacts, hoarding or fencing is set up along the construction site to separate the construction activities from social surroundings. The contractors appointed traffic coordinators, and constructed temporary access to minimize traffic congestion caused by construction. Specifically on each contract:

10. Environmental Protection and Monitoring Measures Implemented in Lianban WWTP
The Lianban WWTP is located at Lianban Village, Gaishan Township, Cangshan District. The WWTP, when completed, will provide wastewater treatment services to an area of more than 90 km 2 on Nantai Island, covering the Cangshan District urban area and the other four areas including Gaishan, Chengmen, Jinshan and Jianxin. The WWTP will treat both domestic and industrial wastewater, and will not only increase the wastewater treatment capacity of Nantai Island, but also protect drinking water sources located at Yuancuo to the north of Min River and Wulongjiang to the south of Min River. Construction of the WWTP Phase I work is still ongoing, and completion is expected at end 2010 / early 2011. The contractor is implementing mitigation measures as required by the full EIA for the Lianban WWTP construction. With the Component B sewers being progressively completed, by end 2010 wastewater can start to be delivered to the WWTP for treatment.
2c: Implementation of Mitigation Measures in Construction Phase for Component C
There are four civil contracts (Yuejin C1, Yuejin C2, Longjin C1 and Puxia C1) under construction in this reporting period. The main construction activities included river dredging, earth excavation, revetment construction and landscaping.
1. Water Pollution Control
In this reporting period, little wastewater is produced in earth excavation, revetment construction and landscaping. Some wash water is generated in cast-in place concrete piles construction at the Dongsheng residential area. Sedimentation tanks have been set up on site for the wash water collection and treatment. The supernatant is reused in water spray to suppress dust. The rivers are all constructed section by section in cofferdams with river diversion to prevent re-suspending the river sediment from causing secondary pollution to the downstream areas. There is no specific labor camp established along the rivers. Workers are housed in rental residential houses in the urban areas. Domestic water is from the municipal water supply system, and wastewater generated is discharged into local sewers.
2. Dust and Exhaust Emission Control
Water content in the excavated earth in the river work is high, so there is little dust produced during excavation. Dust is created at the site where solid waste is temporarily stockpiled or during transportation. The contractors would implement the following mitigation measures to reduce dust in a timely manner.
Yuejin C1: When transporting the excavated earth from the construction site at Dongsheng residential area, dust was created from earth dropping off vehicles. The Contractor instructed the vehicles to run in low speed in the area and sprayed water to clear the dropped earth in a timely manner. There was also dust created from the excavated earth stockpiled at the construction site at the Pencil Mill. The Contractor covered the earth pile before it was disposed off site. Yuejin C2: When transporting the excavated earth from Xinyu Bridge and Gaishan Farm, dust was created from earth dropping off vehicles. The Contractor instructed the vehicles to run in low speed in the area and sprayed water to clear the dropped earth in a timely manner. Longjin C1: When transporting the excavated earth from Chaoyang South Road Bridge, Metro Square and Huawei Transportation Station, dust was created from earth dropping off vehicles. The Contractor (i) appointed 2 workers to regularly spray water to clear the dropped earth at Chaoyang South Road; (ii) covered the vehicles; (iii) imposed speed control on construction vehicles in Metro Square and Huawei Transportation Station; and (iv) cleared the dropped earth in a timely manner. Puxia C1: Water content in river bank landscaping is rather high, so there was no dust produced during construction.

3. Noise Control
Various types of construction machinery are used in construction including grabs, loaders, hoists, air compressors, water pumps, engines, trucks and so on. Their noise level normally ranges from 90 to 108 dB(A), which indicates they are all highly noisy machinery. Construction schedule has been arranged properly and construction vehicles are forbidden to travel at high speed and sound horn to reduce noise impacts on the nearby residents. The following specific actions were taken to reduce noice:
Yuejin C1: Construction at the Dongsheng residential area was suspended at lunch time from 12:00 am to 14:00 pm and night time from 21:00 pm to 6:00am. Yuejin C2: Working hours at Gaohu and Puxia villages were restricted, and some workers were assigned to be responsible for directing traffic and restricting speed and sounding horn. Longjin C1: Working hours at the river rehabilitation work at Metro Square and Huawei Transportation Station were restricted. Some workers were assigned to direct traffic and restrict speed and sounding horn. Puxia C1: The use of high noise machinery was restricted and manpower was used instead in landscaping work.
4. Solid Waste Disposal
During construction of other rivers, both the excavated earth and the dredged material from river channels are stockpiled along the river bank. The contractors used suitable dredged material to construct temporary retaining walls along the rivers to prevent the dredged material flowing back into the rivers and avoid creating secondary environmental pollution. Except for some of the materials reused in construction, most waste materials were transported by construction waste disposal companies to designated landfill sites. On each contract:
Yuejin C1: About one third of the excavated earth was reused to backfill the landside of the revetment, and the remaining was disposed of at landfilll. Dredged material was stockpiled on site for 7 days for natural drying and then transported off site by construction waste disposal companies. Yuejin C2: About a half of the excavated earth was reused to backfill the landside of the revetment, and the remaining was disposed of at landfill. After the demolition waste was disposed of from Gaohu Village in August 2010, the local environment has improved (see photographs in Appendix 4 .) Longjin C1: About 10%-15% of excavated earth was reused to backfill the landside of the revetment, and the remaining was disposed of at landfill. Puxia C1: Excavated earth was used in the landscaping work with little waste produced.
5. Ecological Impacts and Their Mitigation
Some greenbelts have to be temporarily occupied for construction. In such cases, the contractors have to report to and obtain approval from local parks and forestry management department. After the construction is completed at some construction sections, the lands are reinstated by the relevant government departments In addition, slopes of the channel are reinstated with turfing after the construction. This not only contributes to landscaping but also plays a role in protecting the urban ecological environment.
Yuejin C1: About 1 m wide greenbelts were disturbed in river revetment construction at the Dongsheng residential area. They were removed with prior approval by the local parks and forestry management authority, and are to be reinstated after construction. The excavated earth and dredged material from river channels temporarily stockpiled along the river bank were blocked with retaining walls to minimize spillage before being transported off site for disposal. Slopes of some the channel (such as that at the Police College) were reinstated with turfing after construction. Longjin C1: Greenbelts were disturbed in bridge construction at Chaoyang South Road. They were removed with prior approval by the local parks and forestry management authority, and are to be reinstated after the bridge construction is completed.

Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
Longjin C1: The landscaping work includes greenbelt, pavement, railing and stone furniture. This plays a key role in beautifying the urban ecological environment.
6. Historic Cultural Relics Discovery and Protection
To-date there is no report on historic cultural relics and old trees encountered at the construction sites.
7. Social Impacts and Their Mitigation
River rehabilitation in the urban areas would bring certain inconvenience to local traffic, residents, and public facilities etc. In order to minimize the negative impacts, coordination meetings are held with public representatives for their better understanding of the Project and seeking their feedback and supervision. Besides, hoarding or fencing is set up along the construction site to separate the construction activities from social surroundings.
Yuejin C1: The roads inside the Dongshen residential area are temporarily used for construction with the coordination of local security guards for traffic diversion and direction. To minimize the negative impacts on local residents, coordination has been made with the property management company and resident representatives for their better understanding. The underused internal roads in the Pencil Mill are temporarily used as construction access to reduce the impacts on local traffic. Longjin C1: Some sewers, storm drains, gas pipes, telecommunication cables and electric power facilities were affected during construction at Chaoyang South Road, Metro Square and Huawei Transportation Station. The respective authorities were consulted and the Contractor reallocated, reinforced or removed the services as appropriate. On each side of Chaoyang South Road and at the intersection of Metro Square and Xianfeng Road, one coordinator was assigned to divert traffic. To minimize the negative impacts on businesses and residents along the Chaoyang South Road, printed material was used to get public understanding before construction commencement. Longjin C1: The construction area at the Exhibition Center is wide and open and many other projects are concurrently underway there. As there are few public vehicles and passersby, the landscaping work has produced little impact on social activity.
8. Response to Emergencies
The contractors have established a construction safety system, prepared emergency procedures, and equipped with security facilities. All these measures have been approved by the local construction management authority. All construction workers have been equipped with safety helmets and other personal safety equipment, and given safety training. In this reporting period, during inspections by the Fuzhou Municipal Facilities Management Unit at the Gaishan Farm 4+971 bridge under the Yuejin Contract C2 and Chaoyang South Road bridge sites under Longjin Contract C1, hoardings were found to be unsatisfactorily set up. The contractors then made the necessary corrections.

APPENDIX 3: ENVIRONMENTAL QUALITY ASSESSMENT IN CONSTRUCTION PHASE
1. Introduction
FEMS has been engaged to undertake the EEM exercises involved in the Project, and conducted EEM exercises in terms of surface water, ambient air, noise and sludge in this reporting period.
2. Water Quality Monitoring and Assessment
Water quality monitoring exercises to the ongoing Yuejin River contract under Component C were conducted by FEMS in this reporting period. At the same time, the monitoring data of 2009 is listed here for comparison. Except that the Surface Water Resources Quality Standard (SL63-94) is adopted for assessment of suspended substance (SS), the Environmental Quality Standards for Surface Water (GB3838-2002) is used for all the other parameters. The water quality target is Class IV for Yuejin River. Detailed monitoring data and assessment results are presented in Table A3-1.
Table A3-1: Water Quality Monitoring and Assessment Results of Yuejin River

It can be seen from 2009 and 2010’s monitoring data for the Yuejin River that all heavy metals always meet the standards, but SS and organic pollutants exceed the standards with NH 3-N showing the highest exceedance. The general water quality is worse than Class V, showing typical organic pollution. It is believed that the pollution of the river mainly came from direct discharge of untreated domestic wastewater and leachate from domestic garbage indiscriminately discarded along the rivers. In addition, the five parameters which exceed the standards are selected for the two-year comparison. The results are shown in Figure 3-1.

Figure A3-1: 2009 and 2010 Major Pollutants Comparison for Yuejin River
It can be seen that the pollutants’ level in this year is lower than that of last year, but the general water quality still does not meet Class IV. The results do not show that Project construction has contributed unfavorable impacts on the river water quality.
3. Ambient Air Monitoring and Assessment
In this reporting period, the FEMS conducted air monitoring exercises to some selected points near the construction area under Components B and C on Nantai Island. The monitoring

Fuzhou Environmental Improvement Project Nov 2010 Semi-Annual Environmental Report
parameter is total suspended particulates (TSP). These points are located in the Class II functional zone and should meet Class II standard of the Ambient Air Quality Standard (GB 3095-1996). The air monitoring data and assessment results are presented in Table A3-2.

It can be seen that the ambient air quality at the monitoring points meets the standard in this reporting period.
4. Ambient Noise Monitoring and Assessment for the Project Area
In this reporting period, the FEMS conducted daytime noise monitoring exercises at some selected points near the construction area under Components B and C on Nantai Island. Due to locating in different functional zones, different classes of the Environmental Quality Standard for Noise (GB 3096-2008) would apply at the monitoring points. Class IV of the GB 3096-2008 standard would apply at the South Second Ring Road residential area while the stricter Class II standard would apply at the other one due to its location at residential and commercial areas. The noise monitoring data at these points is presented in Table A3-3.

The acoustic environment at the Longjing River monitoring point could meet the standard when there is no construction activity, but the monitoring result shows a high background value of up to 90% of the standard limit value. While during construction, noise level at this point exceeds the limit by only 1.4 dB(A), about 5% exceedance. The noise level at the South 2nd Ring Road monitoring point could meet the standard under construction condition, but the monitoring value is also high. Its meeting of the standard is just due to the Class IV standard limit is comparably low. The monitoring results show that the construction activities of the Project have certain impacts on the acoustic environment, but the major cause should be the high level background noise.
5. Sludge Monitoring and Assessment
In this reporting period, the FEMS conducted a river bed sludge monitoring exercise to the Yuejin River under Components C. The Control Standards for Pollutants in Sludge for Agricultural Use (GB 4284-84) is adopted for assessment. The results are presented in the following Table A3-4, showing that the heavy metal content meets the standard requirement, and the sludge is suitable for agricultural use.

6. Conclusions
In this reporting period, the general water quality of the Yuejin River is still worse than Class V with organic pollutants exceeding standards, which is mainly due to urban pollution along the rivers. However, the heavy metal content of the river bed sludge meets the standards and the sludge is suitable for agricultural use. The ambient air quality at the monitoring points meets the relevant standards. However, the acoustic environment at the monitoring point is affected by the construction activities under the Project to a certain degree, but the major cause should be the high level background noise.
