1.1 Brief

Located in the south of Guangxi, Nanning City is the capital of Guangxi Zhuang Autonomous Region. Under its jurisdiction, there are 6 counties and 6 districts, i.e. Wuming County, Hengxian County, , , Long’an County, , Xingning , , Xi Xiangtang District, Jiangnan Distruct, Yongning District and . The city covers a total area of 22112km2, among which urban area and urban built-up area amount to 6479km2 and over 170 km2 respectively. By the end of 2007, the registered permanent population of the whole city reached 6,835,100 persons, including registered permanent population in urban area of 2,597,700 persons and permanent population in urban built-up area of more than 1,700,000 persons. Flowing through Nanning City, Yongjiang River divides the city into 2 parts – the area at the northern part of the City and the area at the southern part of the city. In the northern area distribute party, government and army organizations, commercial companies, financial agencies, scientific, educational and public health organizations as well as information industry while the southern area is a big park of commerce, service, logistics and industry.

Enjoying favorable geographic position, Nanning is lying in the fringe zone of Southern China, Southwestern China and Southeastern Asian Economic Circles and is a confluence of several economic centers, including China-ASEAN Free Trade Zone, Great River Sub-regional Economic Zone, Pan- Delta Economic Zone, Nanning-- Economic Belt and Beibu Gulf Economic Zone. Besides, it is also an important economic center along Beibu Gulf and a key gateway and passage leading to ASEAN countries.

In recent years, Nanning’s economy has developed rapidly. In 2007, the GDP of the city reached RMB106,299,000,000 yuan, increasing by 10% compared with 2006 and breaking a new record since 1994. In the same year, its energy consumption per RMB10,000 yuan output value decreased by 2.3% while financial revenue amounted to RMB15,084,000,000 yuan, a rise of 25.23%; fix asset investment reached RMB56,022,000,000 yuan, an increase of 25.27% and industrial output value totaled RMB83,088,000,000 yuan, an increase of 29.97%. Whilst rapidly developing its economy, Nanning has also put great efforts and scored tremendous achievements in improving urban environment and constructing ecological city. Since 1995, it has been awarded with honorary titles like “Sanitary City of the State”,“Model City in Comprehensive Control of Urban Environment”, “Garden City of the State”,“China’s Top Ten City in Ecological Environment Construction”, “China Habitat Environment Prize”, “UN Habitat Scroll of the Honour Awards”, etc.

With the ever-increasing progress in urbanization, the fast economic development and the successive increase of the livelihood of the people, environmental pollution has progressively become a major factor withholding the social and economic development. Notwithstanding the successive strength put into the prevention and control of environmental pollutions, deteriorated pollutions along inland rivers still exist, in some sections of the inland rivers, the

- 1 - NIUEP CEA Summary 1 General water quality only remains class V (or worse) of GB3838-2002 –Surface Water Environmental Quality Standards. In the meanwhile, Nanning’s capacity is insufficient in wastewater treatment and coverage of the sewerage pipelines. In 2008, the coverage rate of the sewerage pipelines reaches 52.14%, and the treatment capacity is 440,000m3/d. The wastewater treated takes up 59.9% of the total wastewater volume. Some untreated sewerage (257,700m3/d) has to be directly discharged into urban water system, bringing serious damage to local ecological environment. Also, waterlogging frequently hit Nanning City and cause serious damage. Statistics represents that there were 6 serious floods with the water level of Yongjiang River above 75m since the founding of P.R.China. At present, Fenghuang River, Liangqing River and Lengtang Stream are liable to generate floods and water logging for the former one has very weak flood carrying capacity and limited volume of water storage and regulation while the latter two have not been equipped with any flood control facilities.

Therefore, construction of the project is necessary for enhancing waterlogging control capacity, reducing water body pollution and improving urban water environment It is planed to increase water storage and regulation volume and raise water logging control standards by carrying out comprehensive control to the river courses of the above 3 rivers so as to increase water logging control standards in , Wuxiang New Area and even the whole city to meet the planed requirements, safeguard the built-up urban area around the above rivers and ensure normal production and living of residents. Thus, the project is designed to intercept sewerage along inland rivers, set up separate system, construct WWTPs and associated sewer network so as to enhance the sewerage collection and treatment capacity, increase urban sewerage treatment rate, minimize the pollution of urban water body caused by direct sewerage discharge and effectively improve urban water environment and living condition of Nanning.

Having successfully implemented the World Bank financed Project of Comprehensive Harness of Chaoyang Stream Environment under Guangxi Urban Environment Project and based on the experiences of it, Nanning Municipal Government decided to further cooperate with the World Bank and thus proposed the Integrated Urban Environment Project (IUEP) for the World Bank loan to further promote the integrated management of the environment of key catchment areas and to speed up the process of the improvement of urban infrastructure development, to reduce pollution loads and environmental degradation of the inland rivers and to facilitate the provision of much needed urban infrastructure in selected towns and townships, thereby improving urban environment and assisting further urbanization and economic growth. The total investment of the project is estimated to be RMB 1,518.97 million yuan. Among them, USD 100 million is expected to come from World Bank loan, RMB 473.73 million will be from domestic commercial bank loans, RMB 140 million yuan will be from state subsidy, and RMB 245.24 million yuan will be self-raised by implementing agencies (IAs).

Nanning Integrated Urban Environment Project is comprised of 8 subcomponents covering 2 categories, namely the construction and installation of urban/town wastewater treatment facilities and collection networks and the integrated river environment management. In the project EA, the 8 components are categorized into Urban Wastewater Management (including collection networks) and Integrated River Environment Rehabilitation respectively. The subcomponents are located in 7 districts/counties of Nanning. The subcomponents and corresponding EA institutes are summarized in Table 1.1-1.

With the south higher than the north, Binyang County has a terrain inclining from the southwest to the northeast. Surrounding hills embrace the county from the east, the south and the west but leave an entry in the north where the terrain is relative flat. These hills mainly belong to the eastern branch of Zhenlong Mountains and the branch of Daming Mountains. In the middle of the county, there is an alluvial plain and the build up area of the county is located in the plain.

With low altitude and often affected by the warm and humid marine airflow , Binyang County has subtropical monsoon climate of high temperature and abundant rainfall. Its summer is long and winter is short.

Governing 16 towns, 208 village committees, 22 street committees, 1881 natural villages and 6016 villager groups, Binyang enjoys a total area of 2312.53km2. By the end of 2007, the population totals 990,000 and the population of the built-up area adds up to 115,000, with 21 ethnic groups inhabiting in the county, including Zhuang, Molao, Maonan, Miao, Hui and Yao ethnics. Gross industrial output value of Binyang County reached RMB1.55 billion in 2007.

- 23 - NIUEP CEA Summary 3 Survey of Environment in Project Areas The drainage system in Binyang county seat is a combine system, with mainly culverts and covered trenches in the built-up area. The drainage box culverts were constructed disorderly and lacking of organization, which were laid only under the roads in the newly-built areas. Drainage ditches were set in part of the old districts, while road surface drainage is still existed in other part of the same. As there is no existing WWTP in the county seat, the wastewaters generated are discharged into the drainage ditches after simple treatment in the septic tanks, and then into the surface water bodies in vicinity.

The existing fishponds and a piece of wasteland at the intersection east to Ren’ai Road and north to Longgui Road is selected for the construction of the proposed Binyang WWTP, with the Shajiang Branch Channel to the north. The effluent from the WWTP will be discharged into the Shajiang River, and then into the Qingshui River 15km away. The Qingshui River is one of the main rivers flowing through Binyang County. According to the monitoring data, water quality of the Qingshui River reaches the Class III standard defined in the Environmental Quality Standards for Surface Water, while that of the Shajiang River failed to satisfy the same standard.

By the end of 2007, total population of the county has reached 524,000person, including population in constructed county proper of 43,200, with 13 nationalities including Zhuang, Han,Yao, and etc.

The exposed strata in Mashan County are almost sedimentary rocks. Hilly land is the major landform in Mashan County. Among them, rocky mountains are mainly distributed in the east and the west while earth hills dominate in the middle and the southwest.

In spite of the Hongshui River flowing through the northern area, there are only small rivers in Mashan County. The surface river mainly distributed in the middle and west area, while the underground river imbedded in the rocky mountain area with a depth of about 35m.

Sited in subtropical climate zone, Mashan County enjoys sufficient sunshine, moderate temperature and rich rainfalls. Its summer is long but winter is short while frostless period last almost all the year round. North wind prevails in the winter while south prevails in the summer.

Lacking of a uniform sewerage system, the existing combined drainage networks in Mashan County seat are unorganized. The wastewater flows through the culverts and opened ditches and discharges into the Guniang River running through the county seat from the south to the north. There is a primary sedimentation tank in the Sugar Refinery of the county, in which wastewaters generated from the refinery are pre-treated and then discharged into the Guniang River.

Mashan WWTP is located between the Rongxiu Gas Station and the Mashan Cement Plant, where is about 200m northwest to the Bacao community. The main river in Mashan County is the Hongshui River, and the receiving water body of the effluent from the WWTP is the Guniang River.

With Tropic of Cancer passing across the middle, Shanglin County is located in subtropical area and enjoys a typical subtropical monsoon climate. Warm winters and cool summers, sufficient rainfalls and abundant sunshine are the major climatic features here. In summers, the prevailing wind direction is southeast and in winters, it is northwest. The wind velocity is relatively low.

Rivers in the county area belong to the Hongshui Water System in the Pearl River Catchment area. The Qingshui River is the main river, having 80 tributaries flowing from the northwest to the southeast. The total length of the rivers is 733.80km.

Without WWTP and a complete wastewater collection system, the drainage system in Shanglin County is combined. The sewers installed under the main roads in the old districts are maintained quite well. The outlets of these sewers are mainly distributed along the southeastern bank of the Chengjiang River and the collected wastewaters are directly discharged into the river. In the eastern part of the county proper, there is a trunk drainage ditch, through which the wastewaters are discharged into the Qingshui River directly.

Shanglin WWTP is located near by the Kuailiu community of Huangzhu Village, where is to the north of the old secondary highway of Shanglin. The effluent from the WWTP will be discharged into the Qingshui River, of which the water quality can reach the Class III standard defined in the Environmental Quality Standards for Surface Water essentially.

- 40 - NIUEP CEA Summary 6 Environmental Risk Analysis and Mitigation Measures

6 Environmental Risk Analysis and Mitigation Measures

Major environmental risks of the project are potential environmental risks come from the WWTPs.

Risk 1: Malfunction of wastewater treatment facilities owing to quality problems and mal-maintenance of plants and equipments may lead to a reduction of wastewater treatment efficiency and even lead to a direct discharge; failure of operation of wastewater facilities owing to external irresistible causes such as failure of power supply and eruption of emergent natural disasters may lead to a direct discharge of large volume of untreated wastewaters, which is the ultimate situation of irregular discharges of WWTP. On occasions of failure of normal operation of wastewater treatment facilities owing to power cuts, untreated wastewater will have to be discharged directly to the surface water bodies through a bypass pipe.

Mitigation Measures: 1. Emergency wastewater storage tanks should be set;

2. To establish management and responsibility rules for the operation of the treatment facilities;

3. To train managers and operators to qualify for taking the post and keep files for technical examination of the same;

4. To recruit experienced special technicians with relevant expertise to undertake the work of technical management;

5. To designate special technical personnel for overseas technical trainings;

6. To strengthen patrol and inspection of the conveyor lines so as to detect and sort out potential issues on time;

7. To strengthen the maintenance and management of plants and equipments, and to guarantee the availability of standbys for key plants and equipments; dual circuit must be installed for the power supply;

8. During operation, the windows and the doors of the wastewater pump house must be closed to ensure the noise at the boundary of WWTP meet the requirements in relevant standards;

9. In order to reduce odor emission from wastewater pumping station, it is suggested: to close the collection well; to timely pump the wastewater into the wastewater conveyor trunk for conveying to WWTP for treatment; and to timely cart away debris from the screen.

- 41 - NIUEP CEA Summary 6 Environmental Risk Analysis and Mitigation Measures 10. Networks within the boundary of the WWTP must be separated for rainwater and wastewater, so as to avoid discharges of untreated wastewater owing to overflows in rainstorms;

11. To plant vegetations around the boundary of the WWTP, it is preferable to adopt plants that have high efficiency in the purification of odor substances for the vegetations.

12. To interview the residents living nearby the WWTP regularly for listening to their suggestions. 13. To try by all means to guarantee a normal operation of the screen and sedimentation chambers so as to reduce the SS and COD of the inflow to some extent;

14. To identify the cause from the key pollution sources within the catchment area and to request the relevant enterprise to take appropriate emergency response measures to control the discharge volume of toxic and hazardous substances harmful to microorganisms;

15. On occasions of accidental discharges of untreated wastewater owing to the external irresistible reasons, such as a power cut of the dual-circuit and eruption of natural disasters, some of the enterprises with wastewater discharges must be requested to partially or fully stop discharging wastewater into the networks so as to ensure the functional safety of the water bodies;

16. In the course of handling the emergencies, warning signs must be hung over the water area adjacent the effluent outlets to warn relevant parties for taking precautious measures.

Risk 2: The treatment efficiency of urban wastewater treatment plant is greatly affected by the variation of parameters, namely the volume and the quality of the raw wastewater conveyed to the Plant. According to the national environmental protection laws and regulations, enterprises must treat their industrial wastewater to meet the required standards before their wastewater is discharged and connected to urban WWTPs. Upon emergent accidents such as accidental power cuts, the wastewater treatment facility inside the enterprise is likely to discharge the untreated wastewater into the urban networks and finally enter the newly built WWTP. If the impact loading of the industrial wastewater entering the WWTP is excessively high, the pH value goes beyond the range of 6~9, and the quantity of toxic organism that is difficult to degrade exceeds the standards, it is likely leading to a decline of the activity of biochemical microorganisms, or even to a mutual decomposition of organisms, sludge bulking; and finally it will lead to a deterioration of the effluent water quality (exceeding the national required standards for emissions) and massive adverse impacts on the water environment and ecosystem.

Mitigation Measures: 1. In the design stage, sufficient consideration must be allowed for emergency response

- 42 - NIUEP CEA Summary 6 Environmental Risk Analysis and Mitigation Measures measures for handling the situation unsteady wastewater volumes owing to various reasons, so as to mitigate the adverse impacts.

2. Enterprises with a daily discharge volume larger than 500m3/d must install an online monitoring detector. To ensure the compliance of discharge standards, the enterprises must declare their discharges and the municipal environmental supervisor will make random inspections; the rest of the enterprises must ensure their discharges compliant with relevant discharge standards.

3. The specific enterprises with heavy industrial pollution loads must install accident water storage tanks;

4. When the wastewater treatment facilities of the enterprises operate abnormally and the wastewater is discharged not meeting the standards, prompt actions must be taken by the enterprises to sort out the problems and to inform the WWTP.

Risk 3: Failure of wastewater treatment facility or sludge disposal system will reduce the wastewater treatment capacity, resulting in the effluent waster quality not being able to meet the design standards and/or the sludge not being able to be concentrated and dewatered on time, thus arousing sludge fermentation and overloading of sludge storage chambers, which will finally lead to spreading of serious odors

Mitigation Measures: 1. The dewatered sludge of WWTP must be carted away timely. To use the special closed tankers for the transportation of the sludge, so as to reduce the odor emissions, to prevent droppings on the way and to prevent environmental pollutions;

2. On occasions of abnormal sludge treatment accidents, it is required to repair the equipments promptly and to try by all means to finish the repair works within the time limits for the store of sludge in the sludge chamber; for reduction of odor emissions;

3. Chemicals such as lime must be added to the sludge in time to prevent the sludge from fermenting.

Risk 4: Environmental risks related to wastewater interception conveyors installed in the riverbed, namely pipeline damages and breakages, and infiltration of river water into the pipes, which may lead to the environmental risk of not being able to discharge the effluent flow of WWTP as per the required standards. Low treatment efficiency of the WWTP may appear when there is a damage of the pipe, and the wastewater is diluted by infiltration of the river water. This may even lower the efficiency of the biological treatment and affect the water quality of the receiving water body.

Mitigation Measures: 1. To strengthen patrol and inspection of the conveyor lines so as to detect and sort out potential issues on time

2. Material of pipes adopted should be of good quality on anti-erosion. It is required

- 43 - NIUEP CEA Summary 6 Environmental Risk Analysis and Mitigation Measures that the quality of all pipes, joints and accessories, rubber rings, and relevant materials as such, fully comply with the existing stipulations in relevant national standards, all relevant materials must be accompanied with effective ex-factory qualified certificates and/or relevant documents as such, as well as authentication documents issued by administrative authorities in charge of the management of construction materials; characters of the materials must comply with requirements prescribed in relevant specifications.

3. The administration institution of the sewage interceptors should draw out realistic emergency response and maintenance plan, assign professionals to deal with accidents and responsible for maintenance of the pipeline, so as to mitigate the impact on the environment caused by pipeline accidents.

- 44 - NIUEP CEA Summary 7 Expected Benefits of the Project

8 Comparison and Analysis of Alternative Schemes

Aiming at findining out a scheme enjoying both the minimum environmental impact and the maximum environmental benefits, comparisons have been made to the proposed alternatives in technical, economic and environmental aspects during preparation of the project.

8.1 Comparison and Analysis of Alternative Schemes for Urban

Wastewater Management Subcomponents

8.1.1 Analysis on Non-project Scheme

Although the non-project scheme will not bring new environmental impacts to be caused by the project implementation, the existing urban wastewater treatment capacity cannot meet the requirements of sustainable social and economic development and the increase of local people’s living standards. Besides, the direct discharge of wastewater into environment without any treatment in the 5 counties will undoubtedly pollute the surface water. On the contrary, to implement the project will bring certain environmental impacts, but all other impacts can be avoided or minimized by taking corresponding environmental protection measures except for permanent land acquisition (around 15.56hm2), which is irrevocable. Furthermore, the impacts in construction period is temporary while social and environmental benefits brought by the project implementation and operation will have long-term significance, especially for protection and improvement of water quality of Yongjiang River, Yujiang River, Wuming River, Qingshui River, Guniang River and Shajiang River and upgrading of urban infrastructure. Therefore, the scheme of implementing the project is better than non-project scheme in terms of society and environment. The project construction is necessary.

8.1.2 Comparison and Analysis of Sewerage Network Schemes

Based on local topography and sewerage discharge features, sewerage network should be installed according to the local sewerage prevention and treatment planning so as to guarantee sewerage collection efficiency on the cost-effective basis.

The following factors should be taken into account in the sewerage network construction:

1) To utilize gravity flow as much as possible;

2) To keep away from environmental protection targets (sensitive spots) as much as possible. If the protection targets can not be avoided, mitigation measures should be taken;

3) to be convenient for sewerage collection and conveyance;

- 46 - NIUEP CEA Summary 8 Comparison and Analysis of Alternative Schemes 4) to facilitate construction and future maintenance;

5) to reserve space for future expansion;

6) to select the sites with appropriate geographic conditions and meet the requirements of pipeline construction standards;

7) to save investment and operation cost;

8.1.3 Comparison and Analysis of Site Selection Schemes for WWTPs

Principles of site selection for the other 5 county WWTPs are:：

1) The site should be selected in accordance with the requirements of local master plan and relevant drainage planning；

2) The site selection should meet the requirements of environmental protection, for example: the site should be set up at the leeward of the prevailing wind direction of the town, and there should be a safe distance between the site and the surrounding residential area；

3) The selected site should adapt to proposed wastewater treatment process;

4) The site should be located near the sewerage discharge outlets so as to shorten the length of sewers, save investment and facilitate collection of sewerage within the service area;

- 50 - NIUEP CEA Summary 8 Comparison and Analysis of Alternative Schemes 5) The selected site should be of geographic conditions suitable for project construction and enough space for future expansion;

6) The selected site should be free from flood threats and enjoy satisfactory drainage conditions. The flood control standard applied for the WWTPs should no be lower than the standards for the whole city/county;

7) The selection of the site should involve least resettlement and occupation of farm lands；

8) The selected site should be convenient for communication, transportation and supply of water and power.

Table 8.1-2~Table 8.1-7 show comparison results of various site selection schemes for WWTPs in the light of the above principles.

8.1.4 Comparison and Analysis of Wastewater Treatment Process Schemes

Currently, the A2/O, inverted A2/O, SBR and its modifications, modified oxidation ditch and AB processes, are the mature wastewater treatment processes with favorable dephosphorization and denitrogenation effects in China. The feasibility study report of the project had made extensive analysis and selected the treatment processes of inverted A2/O, MSBR, A2/O and CAST for further comparison. Comparisons of the selected 4 processes showed that the MSBR and CAST processes are the ones popularly used in China. Since there is little difference in the nature of sewerage generated in Nanning and other counties involved in the project, these 2 processes selected for different urban wastewater treatment subcomponents can comply with the requirements of Technology and Policy of Urban Wastewater Treatment and Pollution Prevention and Control and can ensure the treated effluent meet relevant discharge standards. In conclusion, the MSBR process (i.e. modified SBR process) was recommended to Binyang County WWTP, Wuming County WWTP, Hengxian County WWTP, Jiangnan WWTP (Phase II) while CAST process was selected for Shanglin County WWTP and Mashan County WWTP.

8.1.5 Comparison and Analysis of Sludge Treatment Schemes

Sludge disposal is to dispose the stabilized sludge. It is the final treatment process for the sludge transported away from the WWTP. The existing disposal approaches mainly include landfill, incineration, anaerobic digestion and biochemical composting, etc. Considering the economic development and financial capacity of Nanning, landfilling of the sludge is selected because of its lower cost and abundant management experience. All subcomponents will

- 61 - NIUEP CEA Summary 8 Comparison and Analysis of Alternative Schemes adopt the same sludge disposal scheme, i.e. to concentrate and dewater the sludge and then transport it to urban landfill for treatment together with domestic garbage.

Environment Rehabilitation Component

8.2.1 Comparison and Analysis of Non-project Scheme

Although the non-project scheme will not bring new environmental impacts to be caused by the project implementation, the water is seriously polluted because of large amount of sludge in silted the river course that obstructed the flood preventing and discharging, which makes the existing functions of the rivers cannot meet the requirements of sustainable social and economic development and increase of local people’s living standards. On the contrary, to implement the project will bring certain environmental impacts, but all impacts can be avoided or minimized by taking corresponding environmental protection measures. Furthermore, the impacts in construction period is temporary while social and environmental benefits brought by the project implementation and operation will have long-term significance, especially on further improvement of urban environment and infrastructure. Therefore, the scheme of implementing the project is better than non-project scheme in terms of society and environment. The project construction is necessary.

8.2.2 Comparison and Analysis of Specific Schemes

Construction scope of the river rehabilitation component includes river course restoration, rainwater drainage and wastewater interception, and ecological recovery. Comparison has been made based on actual situation of the project areas in the feasibility study, under the principles of aiming at water quality improvement of the rivers, and selection of an economic scheme with better flood control pattern, less land occupation and longer service period.

After comparison, the scheme recommended for river rehabilitation under Fenghuang River Ecological Environment Rehabilitation Subcomponent will harness the river, set an artificial lake with certain regulating capacity and maintain the current installed capacity of the pumping station. The “Dry method” is proposed to use for clean up of the riverbed silt， i.e. to build a cofferdam and excavate a water diversion channel firstly, and then to dig out the silt and transport it to the appointed spots for landfill after water is diverted and the silt at the river bottom is left to become half-dried.

The scheme of setting a regulating lake and flood pump station at the downstream is recommended for river rehabilitation under Liangqing River and Lengtang Stream Comprehensive Environmental Rehabilitation Subcomponent (Phase I). The “dry method” is recommended for sludge clean up under Liangqing River and Lengtang Stream Ecological Environment Comprehensive Control Subcomponent (Phase I). i.e. to dam the river reach by reach for water diversion, and then to add dry earth into sludge and dig out the mixture and transport it to the appointed spots for landfill.

Among them, 2 surveys were carried out formally with consultation meeting as the approach. The first was in the preparation period of the consolidated EA report of the project and the second was after completion of the draft-consolidated report.

The target groups of the surveys consisted of researchers in research institutes, government officers and technicians from the unit in charge of the project.

In the surveys, it is found that the participants all had common awareness that the project should be implemented as early as possible and could analyze and affirm that the project implementation could bring environment benefits. They also gave comments about the potential environmental problems, raised suggestion about the resolutions and required the EA report could be better designed and fully reflect these comments and suggestions. EIA unit has attached great importance to their requirements and adopted their suggestions in the revised report. The focus of the second formal survey was to give specific description and explanation to the environmental issues and compiling issues of the EA report raised in the first formal survey. Please refer to table 9.2-2 for details.

In the second survey, each participant confirmed the solutions to the problems raised in the first survey and expressed optimistic opinions about the implementation effects of the mitigation measures proposed in the EA report and environmental management plan (EMP). In general, it is considered that the project is feasible, all environmental protection measures and EMP are reliable while the EIA conclusions are credible. Table 9.2-2 shows the name of the project, time, approaches, organizers and participants of public participation surveys, major concerns collected and feedback to the concerns in the EA reports.

10 Summary of Environmental Management Plan

Environmental Management Plan (EMP) is developed for mitigating the inevitable environmental impacts produced by the project, proposing technically feasible, financially sustainable and practically workable environmental measures, defining impact mitigation measures, environmental management rationale, suggesting institutional strengthening measures and arrangements for contractors, supervision agencies, operators, environmental management departments during construction and operation, so as to ensure remedial actions for the mitigation of the adverse impacts generated by the project on society and environment and to reduce the impact to an acceptable level.

The role of EMP is to avoid and/or control environmental impacts during implementation of the project and operation of constructed facilities, and to propose such necessary approaches as mitigation measures, monitoring measures, legal and regulatory means and safeguards for the measures above. The EMP acts as a key link between environmental impacts and mitigation measures and alternative measures assessed and described in detail in EA. In EMP, the technological contents, cost estimation, implementation plan, government’s functions, sources of funds and monitoring plan are specified for each environmental management measure. In order to achieve the objective of pollution reduction, the approach proposed in EA report and EMP must be implemented.

10.1 Environmental Management System

According to the Environmental Protection Law of the People’s Republic of China and the Regulations on the Administration of Construction Project Environmental Protection, the review and approval responsibility for the Environmental Assessment Report falls on the Guangxi Environmental Protection Bureau (GXEPB) which is also responsible for the environmental management of this project. GXEPB’s responsibilities are mainly setting out environmental protection requirements based on the EA reports of the project, making coordination between different departments on environmental management, and responsible for organizing the inspection and acceptance of implementation of the “three simultaneous” system of environmental protection facilities. Within the overall administrative framework of the project, the Nanning PMO is authorized by the Nanning municipal government to be fully responsible for the management of the implementation of the project. Under the PMO, the IAs are responsible for the physical implementation of the subcomponents respectively. To guarantee the smooth implementation of the EMP of the project, Nanning PMO, IAs, contractors and operators will designate full-time or part-time personnel to be responsible for the environmental management and to concretely implement the EMP.

Nanning PMO is mainly responsible for project planning and design, and the supervision and management of the implementation of environmental protection procedures, organizing city-wide project environmental management skill training ； Nanning EPB is mainly responsible for the execution of the project environmental management implementation plan and various technical standards and the routine supervision concerning environmental management; Entrusted by the IAs, Nanning Environmental Monitoring Station is responsible for the monitoring of environmental quality in project area during construction and operation;

- 73 - NIUEP CEA Summary 10 Summary of Environmental Management Plan the IAs will entrust environmental supervision engineers to be responsible for the environmental supervision during construction.

The IAs will designate personnel specifically responsible for the environmental management and in charge of: the environmental management at different stages of the project; the implementation of the environmental protection laws and regulations and plans; the checking of implementation of environmental protection measures; the popularization of the use of advanced technology and experience of the environmental protection; the organization of technical training for the related staff in charge of environmental protection of the subcomponents to improve the quality of personnel.

Because of great difference of requirements for environmental management between construction and operation, and the difference of temporary and long-term time frame between them, contractors and operators will establish different organizations at different stages and endow them clear responsibilities by stage. After construction, the corresponding management agencies will be revoked and the operational management agency will operate the constructed facilities. Considering the specific circumstances, an overlapping of time will be allowed for actions to be taken. The institutional framework is shown in Figure 10.1-1.

The project environmental protection supervision plan is shown in Table 10.1-1.

10.2 Environmental Monitoring Plan

10.2.1 Monitoring Objectives

Environmental monitoring involves two periods, namely the construction period and the operation period. Its objectives are: i) to timely have the overall dynamic pollution information of the proposed projects; ii) to understand the extent of changes of environmental quality and the extent of impacts in the project areas caused by the project construction; iii) to understand the dynamic environmental quality during operation; and iv) to make timely feedbacks to superintended authorities so as to provide scientific underpins for the project environmental management.

10.2.2 Environmental Monitoring Institutions

Contractors or operators will entrust Environmental Monitoring Stations in Nanning to undertake environmental monitoring tasks during construction and operation respectively. The entrusted institutions are those that have been certified by national authorities in respect of environmental quality monitoring and with complete equipments and sufficient technical expertise, thus ensuring an appropriate fulfillment of the undertaken monitoring tasks.

Based on the projected results of the EA, the environmental monitoring is to make follow-up monitoring of pollutions during construction and operation, the concerned sensitive points that might probably have obvious pollutions will be selected as monitoring points. Monitoring items can cover areas that might have relatively great impacts on the environment, namely noises, ambient air and surface water environment. The selection of monitoring

- 77 - NIUEP CEA Summary 10 Summary of Environmental Management Plan factors can be made based on the pollution characteristics of specific project. Relevant monitoring analytical methodologies defined in Technical Specifications for Environmental Monitoring issued by National EPA shall be applied respectively. Executed assessment standards will be national standards confirmed in the EA report of each subcomponent.

Detailed key approaches for effective monitoring of activities on construction sites are summarized in table 10.2-1.

The detailed environmental monitoring plans and cost estimations of each sub-component are listed in Table 4-1 to Table 4-14 of Annex 4 of the Environmental Management Plan (EMP).

10.3 Cost Estimation for Environmental Management and Financial Sources

10.3.1 Budget Distribution

The implementation of the measures defined in EMP will involve plenty of units, thus the funds for implementation are sourced variously. An absolute majority of the environmental protection activities are launched through project measures, therefore, the construction contractors and project operators should be responsible for the financial resources and include the same into the cost of their project estimation and make detailed breakdowns in the tender documents.

The budget for EMP is mainly used for the environmental management during construction and operation periods, including costs for environmental monitoring, environmental supervision, personnel training, and operational costs for environmental management institutions. Costs for prevention of risks should also be included in some of the sub-components. Costs for EMC’s activities, water quality and atmosphere monitoring, noise pollution monitoring, and the costs for CSEE and EESI, are covered under financial arrangements for international project management of PMO and IAs. Costs of monitoring and supervision activities of CSEE form a part of the costs for construction and supervision. Local monitoring stations will be responsible for the monitoring of water quality, atmospheric quality and noise pollution as per the requirements defined in the contract entrusted by IAs and the IAs will bear the monitoring costs. The routine monitoring data of environmental protection departments are applicable for the project if the activities of routine monitoring of local environmental protection departments are executed in synchronization with the implementation of the project.

10.3.2 Financial Sources and EMP Budget

Table 10.3-1 summarized the costs for environmental management during construction and operation.

According to the time span of project implementation, it must be guaranteed that the annual budget for project interim payments has included a certain amount of deposits allocated for guaranteeing complete compliances in respect of relevant management requirements for the construction contractors and operators. Table 10.3-2 lists the weighing for deposits of different activities which is to apply as a rate and to be incorporated into the sum of construction contracts.

- 82 - NIUEP CEA Summary 11 Environmental Assessment Conclusions

11 Environmental Assessment Conclusions

The following conclusions can be drawn through comprehensive environmental impact assessment:

1. The project implementation can further speed up the comprehensive environment control of the catchment areas and urban environmental infrastructure construction in Nanning City Proper and Wuming County, Binyang County, Hengxian County, Shanglin County and Mashan County under its jurisdiction so as to create conditions for the harmanious and sustainable development of local economy and society in an all-round manner and the promotion of their urbanization process. At the same time, it is beneficial to the relief of the pressure brought by serious insufficiency in urban domestic wastewater treatment capacity in the 5 counties involved in the project, improvement of local infrastructure and reduction of pollution load in the catchment area of Yongjiang River and Yujiang River. Therefore, the project can bring tremendous environmental and economic benefits and make important contributions to the realization of the objective in the Eleventh-five Year Plan for National Economic and Social Development of Nanning City – “striving to achieve the targets of: breaking through theRMB100 billion threshold total output value; 3 times increase of the per capita output value compared with that in 2000; continuous consummating of the city functions and the rise of urban domestic wastewater treatment rate to 70% in Nanning City and 50% in counties”.

1）After the project implementation, 1 WWTP will be expanded and 5 new WWTPs and their accessorial sewerage networks will be installed, resulting in an increase of urban domestic wastewater treatment capacity of 342,000m3/d. It will enhance the wastewater treatment rate of Nanning City, change the current status of direct discharge of wastewater into surface water bodies nearby without any treatment in the 5 counties, and enable the wastewater to be collected to WWTPs for treatment and to ensure compliance-discharge after centralized treatment, which will in turn promote the protection and improvement of the quality of receiving water bodies in the project area.

2）After the project implementation, comprehensive control will be carried out in Fenghuang River, Liangqing River and Lengtang River. This activity will not only harness the river course of the 3 rivers in a comprehensive manner and improve their landscapes and ecological environment, but also enhance their flood control and discharge capacities, reserve water resource, mitigate water and soil loss, reduce surface runoff and its scouring, mitigate soil erosion so that the serious soil erosion in their catchments areas can be basically controlled. Furthermore, the loss of nutrients in soil will be reduced, agricultural production conditions will be improved and the overall functions of the rivers will be enhanced.

2. The project construction is in conformity with national laws and regulations as well as the urban master plan and environmental protection planning, which also underpin the project implementation as policy and legislation frameworks.

3. The project implementation may involve some environmental protection targets (sensitive spots), such as residential areas, schools, hospitals and natural habitats, etc. Proper site selection has be made in the feasibility study to avoid the above targets (sensitive spots) as much as possible while in the environmental assessment, approaches and methods like

- 83 - NIUEP CEA Summary 11 Environmental Assessment Conclusions analysis on site selection alternatives, adoption of mitigation measures, development and implementation of EMP, public participation and involuntary resettlement have been used to further reduce and eliminate the negative impacts brought by the project implementation to the environment protection targets (sensitive spots) and limit the potential impacts to be within the range stipulated by national environmental protection laws, regulations, criteria and standards.

4. The project implementation may also bring some negative impacts to the ambient environment in both construction period and operation period.

1）the negative impacts in construction period mainly include: the impact of construction fugitive dust to the ambient air quality, the impact of the noise caused by construction vehicles and machines to the surrounding environment, the impact of construction and domestic wastewater to surface water, water and soil loss brought by soil borrowing, dumping of surplus soil, earthwork excavation, backfilling of the site and temporary stacking of earth and gravels during construction of WWTPs, the impact of sewerage pipeline networks installation to local traffics, the impact on aquatic organism owing to river sludge dredging and the destruction of vegetation caused by construction, etc.

2）the major impacts in operation period contain: the impact of fugitive odor emitted by WWTPs to ambient air, the impact of sludge disposal, the impact of the noise generated by pumps to surrounding environment and the impact of tail water discharge to surface water, etc.

5. The negative impacts brought by the project can be controlled to be within the range of level and scope stipulated by national laws, regulations, criteria and standards through the approaches of analysis on alternatives, adoption of mitigation measures, public participation and consultation and involuntary resettlement.

In summary, the project is feasible in the aspect of environment with adaptation of appropriate alternatives, while countermeasures such as mitigation measures, EMP, and public consultation and involuntary resettlement are properly carried out.
