I. INTRODUCTION 1.1 General Introduction This report is the third annual environmental report for the Nanjing Qinhuai River Environmental Improvement Project (the Project), reporting the environmental management activities undertaken in the year 2009. It is prepared by the Nanjing Project Management Office (NPMO) with the assistance of Black & Veatch International Company (B&V). B&V has since October 2007 been providing consulting services to NPMO who is the Executing Agency (EA) for the Project. The Asian Development Bank (ADB) funded civil work contracts have progressively been awarded since 20 September 2007, and construction of the first awarded contract also started in September 2007. This Report focuses on the activities undertaken in 2009 with respect to the implementation of the environmental management plans (EMPs) of the project components. In this Report we briefly provide (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, and (iv) conclusions and suggestions. 1.2 Description of the Project The total estimated project cost is US$ 240 million of which US$ 100 million is loaned by ADB. The counterpart funding of the Project of about US$ 140 million is being provided by a combination of domestic borrowing and Nanjing Municipal Government (NMG) equity. This Project has following five components. Some components comprise sub-components.

• Component A Inner Qinhuai River Sewerage and Water Replenishing - A1 Sewerage Subcomponent - A2 Water Replenishing Subcomponent

• Component B City East Wastewater Treatment Plant, Sewerage and River Improvement

- B1 Sewerage Subcomponent - B2 Wastewater Treatment Plant Subcomponent - B3 River Improvement Subcomponent

• Component C Hexi North District Sewerage, River Improvement and Water Replenishing

- C1 Sewerage Subcomponent - C2 River Improvement Subcomponent - C3 Water Replenishing Subcomponent

• Component D Storm Water Drainage

• Component E Sludge Treatment and Disposal Besides, there is a Component F - Institutional Component, undertaken by B&V. Although not part of the works components, this component is significant for the proper implementation of the Project. It includes policy dialogue and capacity building. It will satisfy the institutional development needs of the NMG and appropriate agencies so that these organizations will have the capacity to manage, implement, and maintain all the Project’s components and subcomponents. One important element in this component is institutional strengthening, capacity building, and training in environmental management. The target includes the NPMO and implementing agencies (IAs) as well as contractors and construction supervision companies. The purpose is to build up the capacity of these entities so that they are able to implement the EMP and environmental monitoring. These components and sub-components can be grouped into the five themes described in Figure 1 and Appendices 1 to 6.

1.3 Description of the Environment 1.3.1 Physical Environment The project area lies in a hilly region of Jiangsu Province, in a river valley formed by Qinhuai and Yangtze rivers. Nanjing city is surrounded by hills on three sides and Yangtze River on the northwest. The typical topographic features are hills, rivers, plains, and islands. The project area is in the northern tropical and monsoon climate zone. Seasonal changes are distinct. The annual average temperature is about 15.4oC. January is the coldest month, with an average temperature of 2.3 oC. July is the hottest month, with an average temperature of 27.9 oC and maximum of 43.0 oC. The average relative humidity is 77%, with an annual average rainfall of 1,041.7 millimeters (mm), mainly during June to September. The maximum rainfall is 1,561 mm and the minimum is 684.2 mm. The maximum rainfall recorded in a day was 198.5 mm. Annually there are 222 to 224 days with no frost. The prevailing wind is from the northeast. The no-wind frequency is 22%. The annual average wind speed is 3.4 meters per second (m/s). The project area lies in the Yangtze River basin. The Yangtze flows through the city from the southwest to the northeast. The major river systems in the city include Qinhuai River, Jinchuan River, and Beishilichanggou. Qinhuai River is a branch of the Yangtze. It originates from Lishui and Jurong counties and flows into the Nanjing urban area via Dongshan Town of Jiangning District. Its total length is 110 km and it has a catchment area of 2,631 square kilometers (km2). Within Nanjing City, from Xibei Village in Jiangning District to Sancha River Estuary, the Qinhuai is known as the Outer Qinhuai River and has a total length of 34 km. Some tributaries including the Yunliang and South Rivers join it along its path to Yangtze River at the Sancha river estuary. The length of the river within the city proper is called the Inner Qinhuai River. Here, it consists of the south, central, east and north sections; the Pearl River; and the City East water system. The Inner Qinhuai’s total length is about 17 km. Groundwater in the project area is mostly contained in loose rock pore water aquifer and base rock weathering fissure water aquifer. In the Nanjing area, this layer is approximately 1 m underground with a depth of approximately 10-20 m. In recent years, it has been in an equilibrium state between extraction and replenishment. 1.3.2 Ecological Resources Nanjing is in a transitional area of mixed deciduous broadleaf and evergreen broadleaf trees and bushes. There are more than 1,373 species of vascular plants belonging to 175 families and 630 genera. Seven plants are protected species at the state level. Fauna recorded in Nanjing include 35 species of wildlife, 216 species of birds, 11 species of amphibians, 19 species of reptiles, and 54 species of fish. State protected species include Chinese sturgeon, Chinese River Dolphin, and the Luehdorfia chinensis butterfly. No rare, threatened or endangered species have been recorded at the project sites. Due to human disturbance, large wildlife no longer inhabits the city. With regard to cultural heritage, Qiqiaoweng Bridge and Nanjing Ming Dynasty City Wall are in the project area. Qiqiaoweng is an ancient bridge built during the early Ming Dynasty. It is the largest ancient bridge in the city and is well protected. The bridge is 89.6 m long, 13 m wide and 25 m high. The Nanjing Ming Dynasty City Wall was built between 1328 and 1398. The total length of the Wall in the city is 33.68 km. 1.3.3 Social and Economic Conditions Nanjing is the capital of Jiangsu Province, and it is one of China’s most important commercial, cultural and industrial centers. Its history spans over nearly 2,500 years. As an ancient capital of China and the site of several key historic events, Nanjing is rich in historical and cultural features,

one of which is the Qinhuai River itself. As of the end 2008, the residential population is about 7.5889 million in Nanjing Municipality and 6.7537 million of which are living in the urban district. Nanjing is experiencing a period of strong economic growth. Nanjing’s 2008 gross domestic product (GDP) reached CNY 377.5 billion with an increase of 12.1 % compared with the preceding year. There is evidence that the fruits of this economic growth are being passed on to Nanjing residents, as the average urban per capita disposable income increased by 13.8 % from 2007 to CNY 23,122.69 in 2008. At the same time, the per capita income of farmers reached CNY 8,951, an increase of 11.6 %. II. IMPLEMENTATION PROGRESS Construction of several sub-components was substantially completed in 2009 including: Inner Qinhuai River Replenishing Sub-component under Component A; City East WWTP, South River Improvement and Wetland Park sub-components under

Component B; and Component D, Storm Water Drainage.

Component E Mount Fenghuang Sludge Disposal Component and the Upper Qinhuai River Improvement Sub-component under Component B have not started construction. Construction of all the other sub-components continues. As of the end of 2009, the overall weighted progress of the Project to date is estimated at about 69 %. The implementation progress of each component is summarized in Appendices 1 to 5. III. ENVIRONMENTAL INSTITUTIONAL STRENGTHENING AND CAPACITY

BUILDING Construction of the Project is undertaken by contractors, supervised by construction supervision companies and managed by the IAs. In order to fulfill the tasks of Component F, during the inception stage of the Project in 2007, the environmental institutional arrangements have been established with personnel designated for environmental management, monitoring, supervision and reporting for the respective components. Their responsibilities and interactive cooperation are clearly defined. There are four IAs in this Project, namely (i) Nanjing Municipal Engineering Construction Management Department (NMECD), (ii) Nanjing Drainage Management Department (NDMD), (iii) Nanjing Municipal Water Company (NMWC), and (iv) Nanjing Qinhuai River Construction Company (NQRCC). They are responsible for all components in the Project with general institutional structure shown in Figure 4.1, and the environmental management structure shown in Figure 4.2.

The environmental management system has been improved and strengthened progressively in this reporting period. All new awarded civil contracts have been managed with personnel designated for environmental management, monitoring, supervision and reporting for the respective components. The activities conducted by and performance of each related party are described in Appendix 6.

Figure 4.2 - Institutional Structure for Environmental Management

IV. IMPLEMENTATION OF MITIGATION MEASURES In 2009, construction activities have produced some unfavorable environmental impacts such as wastewater, dust, noise, traffic congestion and excavated solid waste etc. However, mitigating measures have generally been implemented properly by the contractors. Dusty materials are shielded or covered, the vehicles are cleaned before leaving the construction sites and water spray is used on the dusty ground to reduce dust. In order to reduce noise, construction is conducted in hoarded sites, the use of noisy machinery is avoided as much as possible, and construction activities are scheduled to minimize disturbance to residents’ rest time. Solid waste produced in construction such as excavated earth and dredged sludge is transported along designated routes to designated disposal sites in accordance with the requirements stipulated by the relevant government departments. In order to control any pollution produced from construction camps, drinking water is from the municipal water supply, wastewater is discharged into the local municipal sewer systems, and solid waste is collected in garbage bins and transported to designated municipal landfill sites. As of the end of 2009, there has been no significant impact on nearby sensitive areas. Detailed mitigation measures implemented in each component in this reporting period are presented in Appendices 1 to 5. V. ENVIRONMENTAL MONITORING AND ASSESSMENT 5.1 Internal Environmental Monitoring Internal environmental monitoring at construction sites is conducted by contractors’ qualified personnel and supervised by construction supervision companies. The internal monitoring results are presented in the contractors’ daily records and weekly reports and the supervision companies’ monthly reports. The internal monitoring results show that the environment in the construction areas has been well maintained; no significant environmental problems have been place and no grievances have been reported. 5.2 External Environmental Monitoring Early in 2008, NMECD, NMWC, NDMD and NQRCC have appointed the Nanjing Environmental Monitoring Station (NEMS) as their external environmental monitoring agency. NEMS has since conducted several monitoring exercises to the sub-components where construction has commenced,

Note: PM10 - Particulate matter with particle size below 10 microns TSP - Total suspended particles It can be concluded from the above table that in this reporting period, some items of ambient air, noise and water quality exceeded national standards in different levels. Some of the exceedance should be due to the polluted ambient environmental conditions. For example, in recent years, the average PM10 level in the Nanjing built-up area exceeds the national Class II standard, which shows that the PM10 baseline of the Project was at a high level. At the same time, organic pollution persistently presents in the Project related Yunliang River. Such pollution is a result of many years’ accumulation. Besides, there are also some problems due to the influence of social and transportation activities in the area where the construction is conducted. Having said that, construction of the Project must have some contributions to the unfavorable impacts on the surrounding environment. This requires all IAs and contractors to strengthen measures to mitigate impacts in future construction phase. External monitoring and assessment results obtained in this reporting period are presented in Appendices 1 to 5. VI. OTHERS 6.1 Data Collection Environmental data collected to-date are listed below:

• Internal environmental monitoring forms prepared by contractors; • Environmental supervision monthly reports by supervision companies; • External environmental monitoring forms and report by external monitoring agency; • Two semi-annual environmental management performance reports by NMWC; • Two semi-annual environmental management performance report by NMECD; • Two semi-annual environmental management performance reports by NDMD; • Two semi-annual environmental management performance reports by NQRCC; • Environmental Section in the Midterm Report as of 31 August by B&V; • Environmental Section in the Dec 2009 Progress Report by B&V; and • 2009 Environmental Report by B&V.

Annual Environmental Report B&V has assisted NPMO in the preparation of the first annual environmental report covering the whole year of 2007, which was submitted to ADB by NPMO in Jan 2008 and was accepted by ADB. The second report covering the whole year of 2008 and was submitted to ADB in Feb 2009. This report is the third environmental report covering the whole year of 2009. The next annual environmental report is anticipated to be submitted to ADB in Jan / Feb 2011. Submission of the final annual environmental report for this Project is planned to be made in Jan / Feb 2012. Other Reports In this reporting period, weekly forms from the contractors have been prepared according to the EMP requirements, and submitted to the supervision engineers, IAs and NPMO for review and filing. Monthly reports form supervision engineers have been prepared. NMECD, NDMD, NQRCC and NMWC have prepared their semi-annual environmental management performance reports. VII. CONCLUSIONS AND RECOMMENDATIONS At the time of preparation of this Report, except for Component E and Sub-component B2 – Upper Qinhuai River Improvement Subcomponent, construction activities of all other components are ongoing smoothly. Some of components / sub-components have been completed. To date, the Project has fulfilled the environmental protection and management obligations required by both PRC and ADB. The contractors of all the awarded contracts have generally fulfilled their obligations in protecting the environment and allowed for mitigation measures in their construction contracts and schemes. Through the implementation of these measures, the negative impacts on the environment have been reduced to a minimum level possible during construction. However, to a certain extent there have still been unavoidable impacts on the environment. The monitoring and evaluation reveals that the EMPs have generally been satisfactorily implemented, and the following conclusions can be drawn:

• Since the inception stage of the Project in 2007, the environmental institutional arrangements have been established. In this reporting period, the environmental management system has been further improved and strengthened. All new awarded civil


Feb 2010 (10)

contracts have been managed with personnel designated for environmental management, monitoring, supervision and reporting for the respective components.

• During the construction period in 2009 noise, dust, wastewater and solid waste pollution during construction has been mitigated by relevant measures. There has been no significant negative impact on nearby sensitive areas.

• In 2009, external monitoring exercises have been carried out to some of the ongoing components this year. It can be concluded from the assessment that some items of ambient air, noise and water quality exceeded national standards in different levels in each sub-component. Part of the exceedance problems should be due to the polluted ambient environmental conditions, and part due to the influence of social and transportation activities in the area where the construction is conducted. However, the construction activities of the Project must have some contributions to the unfavorable impacts on the surrounding environment. All IAs and contractors are therefore required to carry out strengthened measures to mitigate the impacts on the environment.

APPENDIX 1 ENVIRONMENTAL REPORT ON

COMPONENT A

INNER QINHUAI RIVER SEWERAGE AND WATER REPLENISHING


Feb 2010 (12)

This component has two sub-components: Sub-component A1, the Inner Qinhuai River Sewerage, and Sub-component A2, the Inner Qinhuai River Replenishing. Both sub-components are implemented by NMECD, and their external environmental monitoring agency is Nanjing Environmental Monitoring Station (NEMS). 1. Sub-component A1: Inner Qinhuai River Sewerage 1.1 Description of the Sub-component This consists of constructing 8.84 km of sewer pipelines in the central and southern areas of Inner Qinhuai River. 1.2 Construction Progress The procurement packages comprise 4 civil (sewer laying) contracts. As of 31 Dec 2009, only Contract A1.1.1 for sewerage pipeline construction was awarded and ongoing. To date, about 3 km pipeline and 33 caissons were completed and the physical work done was about 41%. 1.3 Implementation of Mitigation Measures Construction activities have produced some unfavorable environmental impacts such as dust, noise, traffic congestion etc. During construction, however, measures have been properly implemented by the contractors to mitigate the unfavorable environmental impacts:

Construction wastewater treatment: Concrete was purchased from ready mixed suppliers for the caissons construction. This arrangement reduced alkaline wastewater generation from on-site concrete batching. The contractors have implemented temporary wastewater handling system and obtained the necessary discharge license. Wastewater is filtered before discharge into public sewer.

Dust control: Hoarding has been set up along the construction sites for closure, which helped minimize dust problems affecting the vicinity. Dusty materials were shielded or covered in designated area at the sites, and the excavated material storage duration was minimized to reduce the impact. Construction vehicles for dusty material or solid waste transportation were cleaned before leaving the site and covered or enclosed with speed control. The contractors have taken action to clean any fallen material on the streets to minimize silty runoff on rainy days or dust on dry days.

Solid waste disposal: All the slurry and excavated earth produced in construction was removed off site daily and transported along a designated route to a designated disposal site in accordance with the requirements stipulated by the relevant government department.

Traffic congestion control: Workshops for traffic coordination have been conducted by the IA, supervision company, contractor and local traffic management department for the affected sections of some busy roads. Traffic diversion schemes were proposed and then properly implemented. Some coordinators were designated to assist the traffic police in traffic control.

Noise control: Construction was conducted within hoarded sites, which helped minimize noise affecting the vicinity. Besides, construction activities were scheduled to minimize disturbance to residents’ rest time.

Ecological protection: Some greenbelts or roads were temporarily used for construction. In such case, the contractors have reported to and then obtained prior approval from the relevant government department. After the construction was completed, the disturbed land was reinstated with turfing and planting to reduce soil erosion and maintain the ecological environment.

Historic cultural relic protection: In this reporting period, no historic cultural relic has been discovered at the construction sites.

1.4 Internal Environmental Monitoring The contractor of the ongoing Contract A1.1.1 in Sub-component A1 is Nanjing East Road and Bridge Engineering Company. Mr. Qin Jing has been appointed to be responsible for internal environmental monitoring. He carries out daily inspections, identifies any environmental problems encountered at site and reviews the measures implemented to mitigate the problems. His activities are supervised by Mr. Li Lixian who is the environmental supervision engineer appointed by the construction supervision company, Jiangsu Jianke Construction Supervision Co. Ltd. to ensure proper implementation of the mitigation measures. The internal monitoring results show that the environment in the construction areas has been well maintained, and no significant environmental problems have taken place and no grievances have been reported. The internal monitoring results are presented in the contractor’s weekly reports and the environmental supervision engineer’s monthly reports. 1.5 External Environmental Monitoring and Assessment Day and night noise monitoring exercises were conducted in Aug 2009 and again in Nov 2009, at two sensitive points including Nanjing No.1 Hospital and Huiyuanjie Primary School under Subcomponent A1. The monitoring points are shown in Figure A1-1, and the monitoring and assessment results are shown in Tables A1-1.

The Nanjing No.1 Hospital is located beside a trunk road. As such, a Class 4a sound environment as classified in the Environmental Quality Standard for Noise (GB3096-2008) applies. The Huiyuanjie Primary School is located beside a main street and thus a Class 2 sound environment. The monitoring results show that the noise level from most of the monitoring exercises at the two points exceeded the standard, and only 25 % of cases met standard. Both points are in a noisy environment, and much of the noise come from the busy traffic condition. It is difficult to identify the specific contribution of the Project’s construction to local sonic environment. However, it is suggested the contractor should enhance the mitigation measures and try to reduce the impacts of construction noise on the neighboring residents. 2. Sub-component A2: Inner Qinhuai River Replenishing

2.1 Description of the Sub-component Sub-component A2 consists of (a) constructing the Qiqiaoweng river intake pumping station to divert river water from the Outer Qinhuai River to Hucheng River; (b) restoring the Yueya Lake water gate to divert river water to the Mingyu, Yudai, Qingxi and East Inner Qinhuai River; (c) constructing the east and west box culverts at Zhongshan East Road and constructing new water gates on Mingyu River to control the flow diversion direction. 2.2 Construction Progress Construction of Sub-component A2 was completed in 2008 and there was no construction conducted in this reporting period.

The internal monitoring results show that the environment in the construction areas has been well maintained, and no significant environmental problems took place and no grievances were reported. The internal monitoring results are presented in the contractor’s weekly reports and the environmental supervision engineer’s monthly reports. 2.5 External Environmental Monitoring and Assessment Little construction activities were conducted in this reporting period, so no external monitoring was conducted. 3. Sub-component B3: City East River Improvement 3.1 Description of the Sub-component Sub-component B3 consists of (a) improving 18 km of the Upper Qinhuai River including embankment work, river training and strengthening, river dredging, water and soil conservation, and ecological restoration of revetment; (b) improving the South River with 9.8 km of embankment work, river dredging, water and soil conservation, ecological restoration, and river bank landscape improvement; and (c) constructing a 33 ha wetland park at the confluence of Yunliang and Outer Qinhuai rivers.

3.2 Construction Progress (i) Upper Qinhuai River Improvement portion: Construction of one (Contract A2.3.10 for 2.56

km embankment work from Yunliang river mouth to Qinhuai River Bridge) out of the total eight civil contracts has been completed. Other contracts were awarded at the very end of 2009, so there was no construction activity in the year.

(ii) South River Improvement portion: The civil work was completed in 2008, and there was no

construction activity in 2009. (iii) Wetland Park portion: Main construction work of the two civil contracts was completed in

2008. Interior architectural work has yet been carried out. So there was no construction activity in 2009.

3.3 Implementation of Mitigation Measures 3.3.1 Upper Qinhuai River Improvement No construction was conducted in 2009, so no mitigation measures were needed.

3.3.2 Qiqiaoweng Ecological Wetland Park No construction was conducted in 2009, so no mitigation measures were needed.


Feb 2010 (19)

3.3.3 South River Improvement No construction was conducted in 2009, so no mitigation measures were needed. 3.4 Internal Environmental Monitoring No construction was conducted in 2009, so no internal monitoring was carried out. 3.5 External Environmental Monitoring and Assessment Monitoring exercises in terms of surface water, ambient air, noise and dredged sludge were conducted in the first half year of 2009 under Sub-component B3. The monitoring points and sections are shown in Figure A2-1. The assessment results show that the quality of sonic environment was quite good. While exceedance of standard occurred to surface water and air environment frequently, but it was deemed unrelated to the Project.


Feb 2010 (20)

3.5.1 Water Although there was no construction activity this year, the IA conducted some water quality monitoring exercises to the Yunliang River in 2009. The monitoring parameters were COD, oil, SS and NH3-N, and the Class IV standard was applicable to the river sections. The monitoring and assessment results are shown in Tables A2-1.

Generally, the water quality of the Yunliang River was poor and worse than Class V. The key pollutant was also NH3-N with exceedance varying from 3.6 to 19.5 times. The secondary pollutant was COD. There was no construction activity in this reporting period, so there was no direct impact on the Yunliang River water. Level of the monitored parameters in 2008 and 2009 appeared lower than the baseline in 2006, indicating that the water quality has been improving since the implementation of the Project. The pollutions are believed to come mainly from urban organic pollution and have little relation with the Project. 3.5.2 Air During the period from Jan to Apr 2009, four rounds of TSP monitoring exercises were conducted at Gaoqiaomen close to the Wetland Park. The monitoring and assessment results are shown in Table A2-2. This point is located in an area where the Class II standard of GB3095-1996 applies, and the standard value is 0.3 mg/m3.

Comparing with the previous monitoring data, 36 % of the cases met the standard in 2008 and 40 % in 2006. This indicates that the air quality at Gaoqiaomen has improved. 3.5.3 Noise The same point at Gaoqiaomen near the Wetland Park was also arranged for two-day day and night time noise monitoring in Sub-component B3 during the period from Jan to Apr 2009. The monitoring and assessment results are shown in Table A2-3. The point is located in an area where the Class II standard prescribed in the Environmental Quality Standard for Noise (GB3096-2008) applies. It can be seen that the sonic environmental quality is fairly good. The day time noise level met the standard in all exercises, and only one exceedance at night. As there was no construction activity conducted in this reporting period, it can be concluded that the single exceedance at night was not caused by the Project.

Feb 2010 (25)

3． Sub-component C3: Hexi North District Water Replenishing 3.1 Description of the Sub-component This consists of building a 5.00 m3/s capacity South River pumping station at the confluence of the South and New Qinhuai rivers. 3.2 Construction Progress Construction of all the four civil work contracts have been completed, two of which started and completed construction within this reporting period:

Contract A3.3.1 of Nanhe Water Intake Pumping Station (PS) was completed in Apr 2008, and since then commissioning has also been completed.

Contract A3.3.2 of landscaping in the PS was completed in Jan 2009. Contracts A3.3.3 and A3.3.4 of water intake pipeline started construction in Jun 2009,

and completed in Aug 2009. 3.3 Implementation of Mitigation Measures Work done in this reporting period was little, and only two months was spent to complete the water intake pipeline construction. Construction activities have produced minor unfavorable environmental impacts such as wastewater, dust, noise and solid waste etc. During construction, however, measures have been implemented properly by the contractor to mitigate the unfavorable environmental impacts:

Construction wastewater treatment: The amount of wastewater produced was small, and all was filtered before discharge into public sewer

Dust control:. Water spray was used in a timely manner to reduce dust at site.

Solid waste disposal: All of the solid waste produced in construction was transported along a designated route to the designated disposal site in accordance with the requirements stipulated by the relevant government department.

Noise control: Construction was conducted in hoarded sites. Construction activities were scheduled to minimize disturbance to residents’ rest time.

COMPONENT D

STORM WATER DRAINAGE


Feb 2010 (27)

1. Description of the Component This component consists of 56 drainage sub-components and construction of 27 km of drainage pipelines in the districts of Gulou, Xuanwu, Xiaguan, Baixia, and Qinhuai to improve the flood control capacity of the Nanjing urban area. The total cost of this component is estimated at CNY 80 million. Construction commenced at the end of 2007, and will go on for three years. Successful completion of the component will reduce flooding incidents in the five districts of Nanjing, make the best use of rainwater to replenish rivers, and improve the urban ecological environment. The IA, Nanjing Drainage Management Department, is responsible for the implementation of the Component, and the external environmental monitoring agency is NEMS. 2. Construction Progress There are a total of five civil work contracts under this Component. As of the end of 2009, construction of all these contracts has been completed. Three out the five were implemented in this reporting period. The total completed work is about 34 km.

Contracts A4.1.1, A4.1.2 and A4.1.3 were completed by 2008; Contracts A4.1.4 and A4.1.5 started construction in Jun 2009 and completed in Sep

2009. 3. Implementation of Mitigation Measures In 2009, construction activities of the drainage pipeline produced some unfavorable environmental impacts such as dust, noise, traffic congestion and solid waste etc. During construction, however, measures have been properly implemented by the contractors to mitigate the unfavorable environmental impacts:

Construction wastewater treatment: Concrete was purchased from ready mixed suppliers, and there was no need for concrete batching in-situ. This arrangement has reduced alkaline wastewater generation.

Dust control: The construction sites are hoarded screening out some dust emission. Dusty materials are shielded or covered and the vehicles are cleaned before leaving the site to reduce air pollution. Some workers are arranged to clean the site periodically to prevent dust from generation on windy days.

Solid waste disposal: All excavated earth is transported out of the site as solid waste along a designated route to a designated disposal site in accordance with the requirements stipulated by the relevant government department. The open trenches are refilled with imported suitable material.

Traffic congestion control: Workshops for traffic coordination have been conducted by the IA, supervision company, contractors and local traffic management department for the affected sections of some busy roads. Traffic diversion schemes have been proposed and then properly implemented. Coordinators are designated to assist the traffic police in traffic control.

Noise control: Hoarding has been set up along the construction sites for closure, which helps to screen noise. Besides, the use of noisy machinery is avoided as much as possible. Construction activities are scheduled to minimize disturbance to residents’ rest time. Licenses are obtained for unavoidable night-time construction.

Ecological protection: Some greenbelts or roads are temporarily used for construction. In such case, the contractors have reported to and then obtained prior approval from the relevant government department. After the construction is completed, the disturbed land is reinstated with turfing and planting to reduce soil erosion and maintain the ecological environment.

4. Internal Environmental Monitoring In this reporting period, the contractors of the two civil work contracts are Nanjing Pengcheng Road Drainage Co. Ltd and Tongda Municipal Engineering Co. Ltd. They appointed Mr. Liu Bo and Mr. Yang Guanglin to be responsible for internal environmental monitoring. They carry out daily inspection, observe any environmental problems encountered at site and review the measures implemented to mitigate the problems. Their activities are supervised by Mr. Xun Daorong and Mr. Wang Xin, who are the environmental supervision engineers appointed by the construction supervision company, Nanjing Ningzheng Engineering Supervision Co. Ltd to ensure proper implementation of the mitigation measures. The internal monitoring results show that the environment in the construction areas has been well maintained, and no significant environmental problems have taken place and no grievances have been reported. The internal monitoring results are presented in the contractors’ weekly reports and the environmental supervision engineers’ monthly reports. 5. External Environmental Monitoring and Assessment Both air and noise monitoring exercises at 3 sensitive points were conducted in the period in May and Jun 2009. In addition, excavated earth examination was also carried out at 2 points. The assessment results show that exceedance occurred in most air monitoring cases, but the sonic environmental quality was good. Heavy medal exceedance occurred to one of the two earth monitoring points, so the excavated earth was not suitable for agricultural use. 5.1 Air Three sensitive points were selected separately during the period in May and Jun for five-day PM10 and TSP monitoring in this sub-component. The monitoring and assessment results are shown in Table A4-1. These points are all located in areas where the Class II standard of GB3095-1996 applies. The monitoring results show that not all cases met the standard for both PM10 and TSP at each point. According to several Nanjing Environmental Quality Bulletins in the recent years, PM10 has been the primary air pollutant in Nanjing urban area, and its level has been worse than the national Class II standard. This indicates that the air baseline in the component area has not been satisfactory. The pollution could come from a large number of construction activities conducted in the urban area, and the accumulated impacts have caused the poor air quality.

Since October 2007, the NPMO has organized several sessions of environmental workshops and training, introduced the Consultants in several site visits, instructed the IAs in engaging external monitoring agency and carrying out monitoring exercises, and produced a specific EMP for the construction phase. With assistance of the Consultants, NPMO prepared this 2009 Environmental Report. IAs The designated environmental personnel of each IA are shown in following Table A6-1 with their relevant duties and performance in 2009.

Contractors All the appointed contractors have designated staff from their site management team to be responsible for internal monitoring and management. The designated environmental personnel of the contractors are shown in following Table A6-2 with their relevant duties and performance in 2009. Environmental Supervision Engineers All the appointed construction supervision companies have designated staff namely the environmental supervision engineer (ESE) to be responsible for environmental supervision. The designated environmental personnel of the ESEs are shown in Table A6-3 with their relevant duties and performance in 2009. External Environmental Monitoring Agency The external environmental monitoring agency should carry out external monitoring according to the detailed program and the external environmental monitoring contracts to be produced in consultation with IAs, and provide the IAs monitoring results in a timely manner after each monitoring exercise. All IAs in this Project have engaged the Nanjing Environmental Monitoring Station (NEMS) as the external compliance environmental monitoring agency. In 2009, the NEMS has carried out several rounds of monitoring exercises in the ongoing subcomponents. Consultanting Company, B&V The Consultants, Black & Veatch (B&V) being the implementation consultant appointed for the Project, assists the NPMO and all IAs in environmental management in accordance with the requirements of the implementation consultancy contract between the NPMO and B&V. In this reporting period, B&V initiated meetings with many project related parties and provided suggestions on EMPs’ implementation, reviewed and modified many environmental reports prepared by the IAs and the supervision engineers, and also helped the NPMO prepare this 2009 Environmental Report for the submission to ADB.
