PREFACE

Being located at the central area of Southwest of China, Zhaotong Municipality is the “Dragon tail” of so call “the Changjiang Economic Belt”. It is the important corridor for Yunnan to access to the other provinces and ocean and the “north gateway for Yunnan to open to inland of China. Zhaotong Municipality will enjoys a great prosperity: by 2020, it will be developed into “three Bases and one Barrier”, namely, the important energy base, the heavy chemistry industrial base, and the agricultural produce processing base with special local characterizes, and ecological barrier of upstream of the Yangtze River. By that time, Zhaotong will become the important frontier city for hydro-power development of the Yangtze River, the services base at the middle route of China for “power transmission from west to east”. The central urban area of Zhaotong Municipality is in Zhaoyang District, where the municipal government seats. It is political, economical, cultural and information centre of the municipality. Zhaoyang district is located at the hinterland of “National Panxi—Liupan Economic Development Zone” at the junction among Yunnan, Guizhou and Sichuan, and “land development zone at lower reach of the Jingsha River. Geographically, it is in the centre of the four big cities (Kunming, Chengdu, Chongqing, Guiyang) in Southwest China. It is an important gateway of Yunnan linking with the Changjiang Economic Belt, as well as the corridor of Yunnan to open inward and outward. It is the central urban area of the northeast Yunnan province according to Economic Zoning of Yunnan Province. Zhaoyang used to be the only land way to go if one has to travel from Yunnan to Sichuan and Guiyang on land and communications centre of the well-know China’s “south silk road”, as well as one of the three cultural originating places in Yunnan. Zhaoyang is rich in mineral resources. The proven lignite reserves here are 8.158 billion tons, ranking the send in China. Zhaoyang Industrial Zone is one of the key important industrial zones in Yunnan. Zhaoyang is one of the high-quality commercial apple production bases in south part of China. It is also the hometown of “China’s black –neck crane”. With the advancement of western China opening strategy and driven by the implementation of such key projects as “Free Trade Zone for China—ASEAN” and Power Transmission from Western to Eastern China, and improvement of transportation condition, the position of Zhaoyang be the central urban area become greatly significant. Zhaoyang District is under rapid urbanization process to move towards a medium-sized modern ecological city, locating at northeast Yunnan, influencing Yunnan, Sichuan and Guizhou provinces, integrating industrial, commercial, tourist sectors with strong local characteristics. With the growth of urban population, industrialization and urbanization, and improved improvement people’s living condition, the existing urban infrastructure, such as water supply, sewerage can’t meet the needs of urban development. Water environmental pollution is series in Zhaoyang district. The Governments of Zhaotong Municipality and Zhaoyang District attach great importance to urban environmental infrastructure and urban river courses rehabilitation, plan to seek financial support from the World Bank to implement ZTUEP to drive the improvement of urban eco-environment during the acerbated urban development, and to create a sound environment for the sustainable socio-economic development in Zhaotong. The proposed ZTUEP includes three sub-projects: a water supply sub-project, a wastewater sub-project and an urban river courses rehabilitation sub-project. This plan was strong supported by authorities at national level and the ZTUEP was included as a candidate project in the World Bank’s 2010 lending program.

Yunnan Province and the World Bank have been cooperating in the field of urban and environment for many years, in the nine-five-year (1996-2000) and the tenth-five-year (2001-2005) periods, Yunnan implemented the World Bank financed Yunnan Environment Project (YEP), dominated by sub-projects for pollution reduction of Dianchi Lake Basin. A number of environmental infrastructures of wastewater water collection and treatment, solid waste management were constructed under YEP, which play active role in the integrated Dianchi Lake basin management and improving urban environment in the important urban areas. In order to further promote the integrated pollution control in the key watersheds and improving urban development while acerbating urban development. Yunnan and the World Bank initiated second cooperation in urban environment sector. The Yunnan Urban Environment Project (YUEP) is an on-going WB financed project, approved by the WB Board on May 5, 2009, being implemented in Kunming Municipality, Dali Prefecture and Wenshan Prefecture. During the preparation of YUEP, some sub-projects, triggering the WB safeguard policy OP 17.50 “Projects on International Waterways”, withdrawn from YUEP. Based on the scope of YUEP during the WB project appraisal and willingness of project owners, the YUEP were separated into two phases: YUEP phase I, which is on-going, includes 18 sub-projects with total estimated investment of 1.223 billion RMB, of which 90.0 million USD is to be financed by IBRD loan. Resulting in 60.0 million USD loan saving according to the initial proposed YUEP approved by the State Council to utilize 150 million USD, ZTUEP is to be the a sub-project of YUEP phase II the WB’s additional financing for Zhaotong Municipality to implement enlarged the project development impact, and outcome of YUEP. Yunnan Institute of Environmental Science (YIES) was contracted by ZTPMO on August 2009 to process both the individual EIA for each of the three sub-project and consolidated CEA for ZTPMO. Upon receiving the assignment, YIES, with full communication with feasibility study consultant and based on the initial project scope proposed in the feasibility study, conducted field survey to screen and main environmental issues, determine the scope of EA and standard for environmental assessment. The EA was carried out to meet the needs of domestic EIA requirement and WB EA requirement for category A project and safeguard policies.

While as an urban area located at Jinsha River catchement, the upstream of the Yangtse River, Zhaoyang District in Zhaotong municipality is within the protected area of defined by “Water Pollution Prevention & Control Plan for upstream of the Three Gorges Reservoir” which stipulated that the WWTPs should treat the wastewater with effluent meeting to Class I-B of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant GB18918-2002. Therefore, the effluent water quality of WWTP under this project should reach Class I-B standard. It is also required that all industrial wastewater, existing and the new one, have to be on-site pre-treated to be compliance with GJ3082-1999 Water Quality Standard for Discharging Wastewater into Municipal Sewerage Table 3-5 design influent and effluent quality in WWTP

Sludge treatment: The integrated thickening and dewatering machine is adopted to dewater sludge to the moisture of 80%, then be further dried by adding quicklime to

Page 49 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

reduce the sludge moisture less than 60% and then transferred and disposed at the landfill of Ludian County. Quickliming sludge drying is a chemical drying process: one kg of quickline would consume 0.32 km water, releasing heat. This process has been successfully applied to Hekou WWTP (at south end of Yunnan) by adding 10% of quicklime to machine-dewatered sludge. For this proposed WWTP, quicklime sludge drying process is to be located in sludge stockpile shanty, which is next to mechine sludge dewatering house. The sludge stockpile stanty is to be installed with one rigid impeller feeder, one double-shaft mixer and one sand filter tank. Sludge dewatering process is shown below: Surplus sludge→storing tank→integrated thinkener and dewatering machine→ quicklime drying→sludge cake→hauled to landfill. Reuse of grey water: A certain vulume of treated wastewater (10 m/h) are to be resued within the WWTP for washing compresor, mixer, screen, grit chamber, vehicles pipelines, as well as greenland watering. An integrated grey water purification equipment is designed for this purpose. 3.2.2.3 Sewer networks Design flow of Sewer Network: sewer network will be the permanent infrastructure. Sewage discharging capacity of the sewer network is designed to service the long-term WWTP, e.g. diameter of the pipeline is designed with flow of 120,000 m3/d. Drainage system: the current drainage system in Zhaotong old town is mainly combined system, storm water and wastewater discharge directly into Tuwei River through the same canal. Considering the drainage network of new regions in central city (Qingmen and Taiping regions) is constructed in-phase with the new regions, there is no rehabilitation of exisiting drainage system in general, the separate system is practical. In old town, roads area relatively narrow, buildings are in high density, rehabilitation is difficult and will have great impact on the production acitives and life of people nearby. What is more difficult to resolve is that the drainage system of block courtyard is combined system, the rehabilitation should start from the block courtyard, therefore, the old town will keep combined system currently and use separate system in long term. In the new urban development area, the interceptors along Tuwei River and Wayao River will serve for Taiping sub-zone and Qingmen Sub-zone with area of 29.6 km2. while in the old town area, sewer rehabilitation works includes interception pipelines along eastern ring road, Yingxin Road, Dongmen Xiaohe stream, Tuwei River, Wayao River and Xiushui River. Sewer trunk layout: the terrain of Zhaoyang District is high in north east and low in south west, the sewer trunk will be laid based on the principles that the wastewater is collected by gravity. The installation of interception pipelines along river sides would maximize the collection of sewage and minimize pollution to rivers. Interception pipelines along Tuwei River and Wayao River will be laid along vertical slope of the rivers so that sewage will flow to the WWTP by gravity. Sewage collected by No.1 and No. 2 horizental Taiping sub-zones will be combined at pipeline along Banghan Road, flow through a trund sewer DN 800 along Shengen Road at western side of No.1horizental Taiping sub-zone. At this section, it is difficult to laid the sewere pipeline by means of slot open-cut method because terrain at this section varies significantly. Pipe-jacking method is necessay with total length of 831 m. after pipe-jacking, the pipeline will be linked with the trunk sewer along eastern ring road. Considering the existing and proposed facilities in Zhaotong and structure of northern

Page 50 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT new urban area, the service area will be divided into 5 drainage zones: A, B, C and D drainage zones and the old town drainage zones. Wastewater network engineering quantities: Sewer networks to be construction under this project include: 61.507km sewer pipes in northern new urban area, using HDEP wind pipe, reinfored concrete socket pipe (DN400-1000), including 450 pipe-jacking pipeline (DN 1000) and1869 manholes; as well as 29.541 km sewer pipes in old town, using HDEP wind pipe, reinfored concrete socket pipe (DN400-1200) and 821 manholes. About 45184 m2 of road surface will be open excavated and finally recovered. Wastewater discharge after treatment: a small part of the treated wastewater will be reused in the plant, the other will be discharged into Tuwei River.

3.3.2 CONSTRUCTION ROADS AND DISTRIBUTION OF BORROW PITS Zhaotong Central Urban Environment Project is located in the planned central urban area with convenient transportation conditions. Zhaotong central urban area is 381km away from Kunming-the capital of the province, and about 500km away from Chongqing, Chengdu and Guiyang, the cpaital city of neighbor provinces/municipality. State Road No 213 pass through suburb of Zhaoyang District. The old town is accessible by roads around, the area along the upstream and downstream of river covered by farmland and villages. To the north side of the old town, urban development is underway and planned to be extended into northern new urban area. Urban road network in the north new urban area is taking its initial shape. The existing highways or roads can basically meet the needs of project construction provided that temporary construction shortcuts linking existing road to the new construction site are to be established, especially for river rehabilitation sub-project. Six temporary construction shortcuts are to be established to hauling dredged silts from riverbank to the silt drying pits, which will borrow 1.68 ha of land, including 0.59 ha. of paddy rice filed, 1.09 ha. of dry farmland. Project site is near the biggest cement plant in the Zhaotong, construction material can be tranported directly to the construction site. The scope of the project construction is within the service area of urban water supply, power supply. Construction water can be taken directly from nearby rivers, the construction power can be connected from nearest station; the construction site is wide, the construction

Page 56 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

material can be purchased in market nearby to shorten the transport distance, construction sand is taken from the rivers nearby. Above all, the construction condition of this project is quite good. Zhaotong urban area is widely distributed with Quaternary alluvium and lake sediments, the north part to the old town is gravel layer of expansive soil with poor stability, river terrace within the area is distributed with belt alluvial layer of sandy clay, the south part to the old town is distributed with lake sediments of sandy clay and silt gravel layer. There are 61 sand and stone mines for construction use in Zhaoyang District, it’s proposed to use the sands and stones from 21 sand and stone material plants in Beizha Town in this project, such as Huafeng Construction Material Plant, Hongyue Sand and Stone Material Plant, Yuyi Sand and Stone Material Plant. The advantages of sand and stone material in this area include short transport distance, rich reserve quantiy, good quality and convenient exploitation.

3.3.3 CONSTRUCTION METHODS

3.3.3.1 Installation of Water Distribution Pipelines Generally, piping construction method of water supply project includes open trench excavation, pipe jacking and horizontal directional drilling, these methods all have advantages and disadvantages and applicable under different environmental and geological conditions. Through the comparing feasibility study of these 3 mothods, we believe this area has good condition for excavation as the diameter of proposed water supply pipes is DN1400, along the pipeline is mostly farmland, thickness of soil layer at the top of pipe is about 1.0 m, the depth of pipeline to be installed is shallow, the distribution network is under municipal trunk roads and to be laid in parallel with roads construction. In order to save investment, it’s proposed to use pipe ditch excavation method in this project. 3.3.3.2 Installation of Sewer Pipelines Following the principle of safe, applicable, mature technology, economic and convenient construction, the planning and layout of this project makes use of terrain of urban area, sewer pipeline to be installed is relatively shallow, about ranging between 0.7～4.2m, and pipe diamter is DN400～DN1400. Considering the characteristics of two construction options and actual situation, it’s recommended to use slotted construction method (namely slot open-cut method) for most of drainage pipes, partially, pipe-jacking method will be applied.. 3.3.3.3 River silt dredging Total length of river silt dredging under river rehabilitation sub-project is 48.162 km and total volume of silt to be dredged is 154,000m3. silt dredging in old town uses hydraulic dredging machine and pipe booster conveying methold to ensure the complete and quick dredging; for the sections out of old town, river silt dredging will be carried manually.. River silt dredging methods are shown in the following table:

Method of river silt dredging manually: build dams by river sections (space between dams range about 500~600m), pumping or discharge water in dam and dredge manually after the riverbed comes out. Method of hydraulic dredging machine and pipe booster conveying: build dams by river sections (space between dams range about 700~800m), pumping or discharge water in dam. Set up hydralic dredging machines after the riverbed comes out. Set up the sludge pump and lower it to the designed depth by using high-pressure water syringe to make relatively pit; and dig out a shallow slot at the front of the sludge pump, excavate soil in fan shape and smash it to mud, make it flow to the suction of the sludge pump along the shallow slot, and then convey to sludge disposal site. After the work at one place move the sludge pump to anther place and repeat the same procedures. The process is described in the following chart.

The monitoring results of silts characteristics show that the silts to be desilted doesn’t belong to hazardous solid waste (details are discussed in Section 4.6.3), in which, the silts to be desilted at upstream of the city is not polluted, while the silts within urban area is polluted by urban wastewater and solid waste; therefore, the upstream sludge will be backfilled for planning area, the middle stream sludge will be transported to Ludian Solid Waste Landfill site, which is described in associated project. 3.3.3.5 Hauling method for dredged silts The silt in the river is mostly made by silted sand, earth, stone, solid waste, weed and so on. Solid waste and weed will be transported directly after being excavated; other sand and earth containing large quantity of water will have to be dried before transportation. The proposed transport options for dredged silt are: River sections out of old town: the dry silt dredged from low-lying land can used for reinforcement and backfill of river bank, other silts and weed will be tranported by truck. To reduce the secondary pollution along the route, closed truck is recommended. River senction within old town: conveying by pipes, it’s proposed to use several 6PNL-20 slurry pumps (conveyance distance can be 800~1000m) to boost pressure. The silt will be transported by vehicle for appreciate disposal after drying. The completely closed pipeline can avoid bringing soil and slurry into the roads and so reduce the secondary pollution. 3.3.3.6 Balance of Excavation and Backfill The engineering excavation of the river rehabilitation engineering works is 1394465m3, and the backfill is 588417.7m3. There is more earth excavation volume than backfill and the balance is 806047.3 m3. The new urban district development in north Zhaoyang District of Zhaotong City is under construction presently, where is in need of 900000 m3 backfill for the site preparation. The new urban district development and the river rehabilitation

Page 59 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

sub-project are all in the charge of Zhaotong Municipal Urban Development & Investment Company, Ltd., who could efficiently allocate and transfer the earthwork between several construction sites, and the surplus earthwork of this sub-project could be used for the new urban district development in north of Zhaoyang District, making it unnecessary to setup disposals.

3.4 PROJECT INVESTMENT ESTIMATION AND IMPLEMENTATION SCHEDULE

According the cost estimation made in the Feasibility Studies, the total cost of ZTUEP is 860.3509 million RMB, Of which, water supply sub-project is 334.9566 million RMB, wastewater sub-project is 115.4271 million RMB, river rehabilitation sub-project is 409.9673 million RMB. The project preparation started on March 2009 and to be to completed by mid 2010. The project is expected to enter into implementation phase at the second half of 2010. The engineering construction is expected to be completed by early 2013. It is planned that water supply sub-project will be implemented in 36 months for the two WSPs and water transmission mians, and 36 for water distribution network. Wastewater sub-project in 36 months, river rehabilitation sub-project in 24 months.

3.5 LINKED PROJECTS AND PLANS

3.5.1 REHABILITATION OF OLD TOWN AND WS AND WASTEWATER NETWORKS IN OLD TOWN Rehabilitation of south old town includes: restoration of ancient city and rehabilitation of old town. This project is invested by Zhaotong Urban Investment and Development Company, it’s under construction and planned to be completed in 2010. To resolve the existing problems of wastewater pipes in old town, wastewater network rehabilitation project is being implemented in Zhaoyang District. 49.023 km DN500-DN1500 wastewater pipes will be constructed and 1 sewerage pumping station will be reconstructed, the total investment is 85.45 million Yuan, the project is planned to be completed by the end of 2010. Since the project is located in ancient city and old town, where the roads are relatively narrow, the layout of pipelines of communication, electricity, gas and water is complicated, traffic flow is large and density of population is high, the separate system can be implemented, therefore, the combined system is adopted. Water distribution network rehabilitation works has been commenced since December 2004. A total of 32.11 km of the pipeline with diameter of DN 150-DN 600 were rehabilitated by installing HDPE pipeline manufactured in compliance with GB/13633-200 standard. Such rehabilitation work will be continued in the old town for those pipeline that failed to meet the requirement of standard for water supply.

During WB Preparation Mission of Yunnan Urban Environment Project Phase II at the end of October 2009, dam expert has evaluated current situation of the above 8 dams and issued individual dam safety evaluation report.

3.5.3 MUNICIPAL SOLID WASTE MANAGEMENT SYSTEM The municipal solid waste generated in Zhaotong central urban area is managed by Zhaoyang District Sanitation Station. There is no solid waste landfill in Zhaoyang District yet, a temperory municipal solid waste landfill is in Shantang Village, more than 10km away to the west of urban area, to store simply the municipal solid waste. Due to the constrained funding during the construction period, a simple landfill site design was applied. The site is only equiped with storage capacity shaped by the waste dam, moreover, there’s no antiseepage material, landfill gas operated device

Page 61 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

and leachate collection facilites. The site, as tempoary waste landfill site, was put into operation since September 2006. the disposal ratio is 400ton/day. The environment santatary bureau could only enhence the mangement to reduce the ambient environment pollution to minimum. E.g. The waste received daily will be levelled and treated in time; the waste coverage work will be conducted regularly; fly killing disinfectant will be sprayed regularly; a leachate collection pond is constructed for collecting the leachate and the wastewater and leachate will be separated as much as possible; a interception network is set above the wall for reducing the waste flying pollution; recirculating spraying treatment is applied to natually reduce the leachate volume. According to Zhao (Zhaoyang District) -Lu (Ludian County) Economic Integration Plan, Zhaoyang District and Ludian County will share the public resourses of municipal solid waste disposal facilities. A planned solid waste landfill site in Ludian County, which is 10.8km away from Zhaoyang District, will be funded jointly by state, province and local finance. The planned solid waste landfill site is located Zhaojiahai village with 112.49MU for landuse.

Three large scale hydropower plants (Xiangjiaba, Xiluodu and Baihetan) are under construction downstream of Jinsha River. Zhaotong City is located in transforming part of Yungui altiplanto to Sichuan Basin. There are three rainfall rechage altiplano river systems in Zhaotong City – Lower Jinsha River System, upper Yangtze river system and Wujiang river system, which flow into Jinsha River from southwest to northeast. The runoff are of Jinsha Basin, upper Yangtze Basin and Wujiang Basin is respectively 18976km2, 2755km2 and 692km2. There are more than 390 rivers in Zhaotong, of which the main rivers are Jinsha river, Heng river, Qiulan river of lower Jinsha river system, Yili river, Guan river, Baishui river, Luoyi river; Luobu river, Chishui river of Yangtze main stream; and Yisa river, Poji river of Wujiang river system. The main river system in Zhaoyang district are Sayu river, Zhaolu river and its branch Liji river system, and Tuwei river system. Rising from Taoyuan of Ludian county, Zhaolu river flows through the basin from the southwest end to northwest end, through the four counties of Yongfeng, Mengquan, Tucheng and Jiufu, with the runoff area of 370m2, total length of 26km, width of 15-20m and 2km at the closest distance to the city center. Liji river system and Tuwei river system, locate in the city center, cause most flood in the city. Sayu river and Zhaolu river are in rural area. Liji River system is the branch of the north bank of middle Zhaolu River. The total length of Liji river is 27.1km with an average gradient of 6.6% and control runoff area of 113km2. Rising from Xiaoliang mountain in the northeast of the city, Liji river enters into Zhaolu river from northeast to southwest through Sankong bridge, Lajizhai and Gaolu bridge. It is one of the main flood protection rivers in Zhaoyang city. Tuwei river system is a branch of Zhaolu river with an runoff area of 124km2 and an average gradient of 8.9%. Rising from Liangfengtai in the east of the city at an altitude of 3151.8m, the river flows through the urban area and merges into Xiushui river, Yaowan river and Dongmen river at Shuangyuanzi in south suberb and finally enters into Zhaolu river. Tuwei water system frequently causes servious flood in the city. Feature of river systems are attached below. （5）Ecological Resources The complication and diversity of the terrain and climate contribute to rich biology resource in Zhaotong. There are 1025 species woody plant which belong to 457

Forest coverage in Zhaoyang District is 20.81%, including 997,799 mu of non-commercial forest, 792,112 mu of logging prohibited forest, 205,687 mu of restricted logging forest, and 239,521 mu of commercial forest. The main types vegatation include: arid sparse defoliate and broad-leaved forest vegetation, mixed forest vegetation of semi-arid evergreen and coniferous, cold clouding evergreen-leaved, broad leaved forest vegetation, mixed forest vegetation of warm clouding coniferous and broad-leaved, and cold clouding shrub & brushwood vegetation. Zhaoyang District has total land area of 205,578 hectare. Existing Land utilization condition in 2008 were: 72,643012 ha. of arable land accounting for 33.7%, 9,893.06 ha. of garden plot accounting for 4.6%, 71,001.36 ha. of forest land accounting for 32.9%, 21,537.48 ha. of grassland accounting for 10%, 8,448.58 ha of land used for urban, village housing, mining and industries accounting for 3.9%; 1,033.83 ha. of land for transportation use accounting for 0.48%. A total of 20,477.58 ha. of land have not yet been utilized, accounting for 9%. Ecological conditions of rivers to be rehabiliated: z River banks: land areas along sections outside urban area of Liji, Tuwi, Xiushui and Yaowan Rivers are donimated by arable land and paddy rice field, on which such crops of wheat, corn, cabbage and radish are regularly planted, while the land along sections inside urban area of Liji, Tuwei, Xiushui and Yaowan Rivers that passing through downtown are used as urban residential area. z The riverways; riverways of Liji and Tuwei at urban sections have been channelized and highly silted with incomplete ecological function. Fishes in urban sections of these rivers have been vanished. Fewer plankton (mainly algea), weeds (mainly sub-merged macrophates) can be found in these sections. Such invertebrate as earthworms can be found in the river sediment. The riverway is characterised by typical benthonic invertebrate. ecosystem z The silt drying pits: the silt drying pits selected in the feasibility studies are located in areas with intensified human being’s activities. There are no primeval vegetation. It is mainly covered by herbs or farming crops. In summary, these silt drying pits is characterised by distinct farming eocsystem with simplex biodiversity. No any rare species can be found here. The pits do not belong to any functional habitates. （6）Mineral Resources With excellent conditions for mineralization, Zhaotong City is rich in mineral resources and advanced in mineral development. Amount the 33 types of mineral there are 22 types with proven reserve, including coal, sulfur, zinc, silver, magnesium, phosphor, silex etc. high in quality and abundant in reserve. The reserve of coal is 18.95 billion ton covering 36.3% of the total reserve in Yunnan Province. The reserve of lignite

Page 65 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT covers 44.3% of that in Yunnan Province. The pyrite mine area in Zhaotong is one of the largest mine ares in China and one of the three largest non-ferrous metal bases in Yunnan Province. The north urban area to be developed in Zhaoyang District is withins the wood coal mine area. （7）Tourism Resources Zhaotong is a place of both natual and historic figures and cultrual heritage, which is a good tourist resort with unique natural scenery and ethnic folklore to be developed. （8） Nature reserves Dalongdong, located at Beizha Town to the north of Zhaotong City, is established in 1981 as provincial nature reserve. It’s 134ha, in which 69ha for forest, 27ha for coutryard and 38ha for river. In July 2007, based on the prevous nature reserve area, Dalongdong is divided as drinking water souces protection area. The protection area is extended to 314ha that 12km to Zhaotong City. Dalongdong is a famous nature landscape protection area for its historic Taoist temple, ancient constructions, etc. the objectives for protection include: water conservation forest, water sources, natural landscape. The protection area is the water source intake of Qingmen WSP in WS sub-project. The raw water transmission network is already constructed and there will be no more construction works in this project, thus there will be no impact on the project. Yudong Reservoir: It locates in the Jule River which belongs to Jinsha River system. This reservoir is 23 km away from Zhaotong city. The basin area of Yudong Reservoir is 709km2, and the total stroage capacity is 364 million m3. This is the only stable and reliable water source for Zhaoyang District and agricultural water source for Zhao and Lu dam areaes. The general target of water source protection for Yudong Reservoir include: On the premise of guaranteeing the public health, the water quality of Yudong Reservoir first class area should reach the Class II and above Class II standard of Surface water environment quality standard. According to the current status of Yudong Reservoir that the sand sedimentation is serious and the environment parameters, total phosphor, total nitrogen and E.coli, are between Class II and Class III, measures are adopted to plant trees and control water environment pollution. Based on the principle of “ Unified planning, unified funding, unified treatment, unified protection, gradual treatment and gradual improvement”, and in order to realize the essential objective for the water resources protection of Yudong reservoir, it’required that 1)water quality of the first Class area should reach Class II and above Class II water quality standard; 2)forest coverage rate above 1985 meter should reach 100%; 3)the forest coverage rate of the second class area should be above 85%. It’s expected to achieve a virtuous cycle of water resources and aquatic ecoenvironment through the improvement of integrated management level of water resources by protection and rehibilitation. In this way the development, utilization and protection of water resources would be developed synchronously with society and economy, which would ensure the max eco and social benefits Dashanbao: it’s seated at 79km western to Zhaoyang district. The total area is 192km2 with 2800m for average elevation. It’s approved as National Nature Reserve by State Council in 2003, which is a key wintering habitat for black-necked stork. The project will not be affected as Dashanbao is far from the project lcoation and not included in the EIA. Putaojing: located in Jiupu Town, about 10km away from Zhaotong City. This is not only a famous resort place but also the locality of “Six ancestors branching” which has a great impact on the development history of Yi nationality. This is the holy land for ancetor worship of Yi fellow.

4.1.3 HISTORICAL RELICS Zhaoyang district, with long historical cultural relics, has rich cultural relic protection department in different levels. After discussion between local project, owner, EA unit and local cultural relics protection management department, as well as the site visit, it’s discovered that the key cultual relics in project area stays at the Wanghailou west to Tuwei river. Wanghailou is about 2km away from Zhaotong City and about 100m to the west of Tuwei River that was built by SHEN Shenglin, the county magistrate of EnAn county in 1760. in order to protect this building and protect the potential precious cultural relics during the project construction, Zhaoyang District cultural and Sport Bureau, the local authority responsible for relics has issued a letter for the project construction, specially commented the details for cultural relics protection during the project construction. The letter from Zhaoyang District cultural and Sport Bureau is attached as annex 1of this report:

4.2 EXISTING WATE SUPPLY AND DRAINAGE SYSTEM AND URBAN RIVERWAY

4.2.1 CURRENT SITUATION AND MANAGEMENT OF THE WATER SUPPLY AND SEWERAGE SYSTEM The water supply in Zhaotong central area is supplied by Zhaotong Municipal Water Supply Company which is a state-owned enterprise established in 1963 and belongs to the Construction Bureau of Chaoyan district. The water company owns 5 WTPs and 1 WWTP with 264 permanent staff. It has the following departments: administrative office, financial dept, laboratory, design office, billing&operating dept, tariff collecting group, information center, network management office. 4.2.1.1 Current Water Supply Facilities and Capability There are 5 WSPs in Zhaoyang District with the respective capacity of 5000 ton/day, 10,000 ton/day, 5,000 ton/day, 5,000 ton/day and 40,000 ton/day. The total capacity in Zhaoyang District is 65,000 ton/day. Amoung the 5 WSPs, the WSP No. 2, 3 and 4 take undergroud water and are currently suspended for alternate water source. WSP No.1 takes raw water from Dalongdong spring and supplies the residents directly without treatment. Due to worn equipment and out of dated process, it’s basically out of use. WSP No. 5 takes water from Yudong reservior and the effluent water quality is stable. The water in urban area of Zhaoyang district is mainly supplied by WSP No.5 and No.1. The water in the central urban area is supplied by WSP No.5. WSP No.1 will supply the raw water without treatment directly to the large customers concentrated in the north area close to the train station. The large customers include: trian station, pharmaceutical factory, etc, with the consumption of water respectivly 1500m3/d, 600m3/d and 2000m3/d. other water for domestic and industrial usage is from shallow ground water. The drinking water comes from untreated surface water and shallow

Page 68 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

ground water (well water) that is not up to standard. The increasing of waterbone diseases of local population directly affected the local health of population, economic development and social progress. The average daily water supply by WSP No.1 and 5 in 2008 is 34000 ton/day. The consumption of surface water and shallow ground water (well) as drinking water is 20,000 m3/d. Water distribution pipelines have been installed underneath amost all the existing urban road, constituting a network combining ramiform and ringy shapes. Water distribution network in the old town is ringy shaped while network in new urban area is ramiform shaped. The maximum diameter of existing water distribution pipeline is DN 800. Total length of pipeline with diameter greater than DN 65 is 130 km. these pipelines are made of cast iron or PE. Most network in the old city of Zhaoyang district were cast iron pipes with small diameter that constructed in 1960-70s, which suffers from unbalanced water supply and serious leakage. 4.2.1.2 Problem of the current water supply system （1）Urban residents who are not served by the centralized water supply suffer from the unqualified water quality due to the untreated water supply of surface water and shallow ground water. This resulted in the increasing of waterbone diseases of local population that directly affected the local health of population, economic development and social progress. （2）Zhaotong city faces a good chance for society and economy development and city construction because Zhaotong city becomes more and more important as regional centre. The construction in north part of Zhaotong city has been carried out quickly. Many key projects are under construction. However, the infrastructure in urban area is still insufficient. There is no water supply system in the planning area which is greatly restricted the development of this area. （3）The water supply network in Zhaoyan District old town is laid in 1960s and 1970s. All the pipes are cast iron pipe due to the constrained construction condition at that time. The diameter of water supply pipe is relatively small. And the layout of it is not rational and the water distribution is poor. （4）According to existing national standard, all the existing network could not reach existing hygienic standard of water supply, especially water quality of some areas could not reach the standard because of the poor water supply network while the water quality of water supplied has reach high quality after the completion of Yudong WSP. 4.2.1.3 Current drainage network and existing problems Existing drainage main pipe network in the planned urban area exists only in the old town. There is no complete municial drainage network in north new urban area. All the stormwater, industrial wastewater and domestic wastewater from urban area are discharged into Wayao and Yaowan River. This disposal of wastewater has threatened the water use of downstream. The planned urban area is shaped north-south trending. The north part is high and the south part is low. There are one river on each side of Zuti Road where some irrigation canal are scattered around. The drainage system in old town region is conbined system. With the development of the city, there are four wastewater main pipeline constructed in old town. The total length is 12.65km. without unified planning, the drainage channels in old town are basically constructed together with the construction of the city. Due to the

Page 69 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

uncompleted collection pipeline system, especially in those area with high density of population, e.g. Zhonggou river, Dongmen river, Wayao river bain, the domestic wastewater and large volume of industrial wastewater are directed discharged into river that resulted in severe pollution to the river water. The construction of urban infrastructure in central new town is implemented by following general planning. The environment protection facilities in the new town is lagged behind the development of Zhaotong city. Much urban domestic wastewater and industrial wastewater is discharged directly into rivers without treatment because of the un-complete drainage network. The discharged wastewater not only pollutes the water environemtn (including the riverway sedimentation and water deterioration) but also threatens the public health. Currently these are the key complains received from the urban residents. 4.2.1.4 Current status of WWTP and existing problems Zhaotong WWTP locates in Zhaoyan District, east bank of Tuwei River. It is 10km away from Zhaoyan District. The construction of WWTP is by 2 phases. The capacity of 1st phase is 60,000 m3/day. The total area is 136.8 mu. Zhaotong WWTP adopts oxidation ditch process for treatment. The treatment plant treated 17.9262 million m3 wastewter in 2008. The average treatment amount is 49,000 m3/d. The WWTP is no facing following isses and to be addressed under proposed project activity: z The treated effluent were discharged into Tuwei river without desinfection due to the lack of desinfection facility; under this project desinfection system will be provided for both the old and new treatment facilities; z There is no on-line monitoring system and the quality of treated effluent can not be prmptly monitored. Under this project, COD on-line monitoring instrument will be installed as short-term program. In the long-run, TN and TP on-line monitoirng instrument will be installed; z Short retension time in the oxidation reaction ditch (9.5 hours) was the main reason of unstable treated efluent quality. Under this project, the extension of treatment capacity will increase the retension time of reaction tank to ensure treated effluent be compliance with Class 1-B of GB 18918－2002; z Preportion of surplus sludge were disposaed of in landfill with moisture higher than the reuqirement of municipal solid waste landfill on sludge. z Structure of wastewater disbtribution is only enough to distribute wastewater lifed into existing 2 treatment groups, a new distribution well need to be constructed to to meet the need of this project extension, as well as the long-term treatment capacity of 120,000 m3/d. According to the analysis of actual operation data of Zhaotong WWTP from Jan to Dec 2008, the BOD5 in effluent could not reach Class I-B standard due to the increasing of BOD5 in influent in dry season. The reason is that the treatment capacity for BOD5 in design is too small to treat the whole wastewater. Meanwhile the NH3-N in effluent is high in rain season that cannot meet the requirement of Class I-B standard because much rain water flow into the worn-out drainage network. The rainwater reduces the carbon source in influent thus cannot meet the requirement for denitrification. With the extension the urban area and improvement of drainage network, the wastewater collected and the concentration of BOD5 in influent would increase yearly. The existing WWTP could not meet the requirement of treatment capacity of 60,000 m3/day.

4.2.1.5 Current status of WWTP sludge disposal There is no municipal solid waste sanitary landfill site in Zhaoyan District at present. The municipal solid waste is disposed of in a simple landfill site. The sludge of existing WWTP in Zhaoyan District basically contains whiffy debris of organism. Annual sludge is around 10950 t/a, with moisture of 80%. Part of sludge is stored inside the WWTP for local farmers use as agricultural manure for nursery. Part of sludge hauld by WWTP operator or local environmental sanitation station to the simple landfill site for disposal. Sanshantang temporary municipal solid waste simple landfill site, west to the city,is 10 km away from the WWTP.

4.2.2 CURRENT STATUS OF URBAN RIVER AND MANAGEMENT

4.2.2.1 Current status of urban river way and its management Zhaotong Municipal Urban Construction Investment & Development Co. Ltd, is the implementation agency for river rehabilitation sub-project. After the project completion, the operational management of rivers rehabiltated will be hand over to Water Conservancy Bureau of Zhaoyang District. The main rivers in Zhaoyang District are Sayu River, Zhaolu River and its tributaries Liji River and Tuwei River. The Liji River and Tuwei River flow across the planning region. Zhaolu River originates from Taoyuan, Ludian County. It flows from southwest to northwest. The river flows across towns of Yongfeng, Fenghuang Residential District Office and Jiufu. The nearest distance away from the urban area is 2 km. The river, with 26km for total length and 370 km2 for the river basin, is 15~20m in width. Liji river, a tributary of and at right bank of Zhaolu River, is located at the center of the urban area. Sayu River and Zhaolu River is in suburb. The Liji River and Tuwei River is the main cause for flooding the urban area. Liji River is long 27.1km and the average gradient is 6.6%. The control runoff area is 133 km2 originated from from Xiaoliangshan (2667.7m). It flows in a direction of northeast-southwest, passing by Sankong Bridge and Lajizhai finally flows into Zhaolu River in Gaolu Bridge. This is one of the important river for flood control in the urban area of Zhaoyang District. Tuwei River is first-grade tributary of Zhaolu River. The runoff area is 124 km2 and average gradient is 8.9%. it’s originated from Liangfengtai east to the urban area, which has a altitude of 3151.8m. Tuwei River flows in a direction of northeast-southwest. It acrosses the main urban area passing by Xiushui River, Yaowan River and Dongmen River at Nanjiao Shuanyuanzi, and finally flows into Zhaolu River at Heinidi. The river systme is showed in attached map. Tuwei River is a river with many problems. The main stream and tributaries of the river require regulation. Liji River and Tuwei River are the key rivers for rehabilitation. The geographic parameters of two rivers are listed in the following table.

There is a river management station under this bureau. 8 staffs take charge of the maintenance and management of urban river. The main responsiablity are: to manage the river daily by following “Water Law”, “Flood Control Law”, “Management Regualtion of Riverway” and “Yunnan Flood Control Regulation”. 4.2.2.2 Main existing problems （1）Serious water pollution The main rivers in urban area are Tuwei River and its tributary Liji River. The rivers have been the wastewater receving water body for a long time because of the impact of city activities. However the wastewater collection system has been established at the beginnig of this century. The poor drainage system in old town leads to serious pollution in the rivers. There are 112 discharge outlets along Tuwei River and 43 outlets along Liji River. Most of the building along the river are constructed next to the river and the wastewater interception network could not be installed. Some wastewater from buildings and villages near the rivers is discharged into the river directly. Zhaoyang District develops quickly in recent years and the north new town is under construction at present. urgent installation of wastewater collection facilities is necessary so as to prevent water pollution. The water quality of upstream of Liji River is good. There are farms and some residents living near the river. When the river flows across the urban area, solid waste and wastewater would be discharged into the river that somehow has related impact on the water quality. Tuwei River has not beening polluted seriously without large polluters alone the river sides. However, after the river flowed through the urban area, water quality becomes poor because of the serious pollution and riverway sedimentation. According to The Surface Water Aquatic Environment Functional Zoning of Yunnan, Zhaolu River, Tuwei River and Dongmen River all belong to Class IV water protection area. The main function of these areas is water for industrial use. In recent years, the water qualities in thess rivers have become Class V as the increasement of pollutant in rivers. （2）Serious river siltation

With the increasing of population, the activities of human being have destroyed the ecological equilibrium. Land reclamation, farming, and woodcutting result in the serious water loss and soil erosion, reduction of vegetation and desertification. The

Page 72 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

direct result of reduction of vegetation is the river sedimentation casued by sands and soil. Some residents built their houses on the river bank resulted in the more and more narrow of the river. The residents have bad habit and poor environment protection awareness that they throw waste into the river at random. The waste in the river and irregular cleaning result in the pollution and sedimentation of river and reduction of river width. In middle of Liji River, the area of waterway before Sankong Bridge is only four fifths of design value. In Shuangyuanzi section of Tuwei River, it is only two thirds of the design waterway. The riverbed is 1m higher than the farmland and resident house because of the river sedimentation. Some section is even higher. The river sections in urban area is silted and conteminated by receiving untreated wastewater and domesitc soild waste. Silt in Tuwei River trends to become more black and smelly. （3）Riverway requires urgent cleaning and regualtion Zhaoyang District has a long history. The construction of riverbank is finished in several period, most of which are built before 1990s. About 40% of these banks are made up of soil. The width of the bank is 4 meter. These banks are eroded seriously and easy to occur accidents. The riverbank in urban area is made up of grouted stone. There are unreasonable occupancy of riverway along this section. The type, structure, scale and material of riverbanks in different period are different. The old bank is in a poor condition at present. Most of the banks could not reach the relevant requirement when designing. And there are several dangerously weak reservoirs in upstream of urban area. All these factors are potential damage to the riverbank and peoples’ lives.

Data source: Zhaotong EMS Assessment is based on water quality monitoring result from the section of Fenghuang watergate on Tuwei River in 2007 and on Jan., Mar.,May, Jul., and Sept. in 2009. Since the municipal waste water from the old town of Zhaotong city is yet to be collected and directly drained to the river, the water quality of Tuwei River is relatively poor. Detail analysis is as following: The monitoring parameters of Fenghuangzha monitoring section in Tuwei River in 2009 are 5. The monitoring results shows there are 4 paramenters exceeded Class IV water quality required in Surface water environment quality standard (GB3838－2002).

The 4 paramenters that exceeded the limites include CODMn, CODCr, BOD5 and NH3 －N, the exceedance times respectively is 0.22, 0.97, 1.7 and 6.08. Thus, we could know that the water quality of Tuwei river cannot meet the requirement of Class IV standard of GB3838-2002. the main pollution comes from organic, nitrogen and

phosphorus. The biggest pollution comes from NH3－N that is a major cause for the Tuwei river pollution.

4.3.2 CURRENT STATUS OF AIR ENVIRONMENT QUALITY According to Zhaoyang air monitoring result conducted by Zhaotang EMS in 2007, the annual average of air quality in project area in comparison with Ambient air quality

standard (GB3095－1996) are: NO2 and inhalable particle are Class II; SO2 is Class III that exceed the requirement of Class II. Observation from the change of the year, NO2 and inhalable particle reach the standard all the year. SO2 reaches the standard only in June, July and August. SO2, as the main cause of pollution, comes from the sulfur coal that cause the increasing emission of SO2.

the range for resettlement. However the resettlment is within the range of the resettlement scheme in new area planning but not in this project. The proposed Qingmen WSP, located close to Zhaotong rail station, is at opposite side of Paoma road and Taiping Village. It’s used as coal yard and corn field.

4.3.4 CURRENT STATUS OF ECOLOGICAL ENVIRONMENT

（1）forest resources The forest coverage in Zhaoyang district is 20.81%, in which public profit forest 997799mu, Lumbering forbidden area 792112mu, lumbering control area 205687mu, Merchandise Forest 239521mu. There are many types of vegetations. （2）current situation of land utilization Zhaoyang district serves an area of 215578ha. The land utilization in 2008 is: 72643.12ha for farmland (33.7% of the total); 9893.06ha for garden (4.6%); 71001.36ha for forest (32.9% of the total); 21537.48ha for grassland (10%); 8448.58ha for urban & village and industries and mining (3.9% of the total); 1033.83ha for the transportation (0.48% of the total); 20477.58ha for vacant land (9% of the total). Zhaoyang district has used land 195100.42ha in 2008, which is 91% for the land utilization (the land utilization ratio in Yunnan Province is about 87%). The selected sites for Taiping and Qingmen WSPs are designated to be land use for establishment of environmental and sanitation facilities by “Control Detailed Plan of Zhaotong City Masterplan (2007-2020)”, thus there will be no farmland occupation by WSPs. Water distribution pipeline will be installled along the two boundary sides of planned north new urban area (now under initial urban development stage) and Zhuti avenue in the middle where the existing land use patterns are farmland, and street trees. These area are covered with artificial vegetations with no natural and primal vegetation. Land to be temporarily borrowed for water transmission pipeline construction is mostly dryland, irrigation field and woodland. And the main crops are rice, tabacco, corn, patato, buckwheat and so on. Forest coverage along the water transmission pipeline area is merely 13.7% due to deforestation, irrational land reclaimation and livestock farming. The ecosystem in the district is single and mostly covered by planted timber, economic trees, protective forest and natural shrub, and the tree species include Pinus yunnanensis, Pinus armandii, poplar, apple, yellow pear and so on. Animals are mostly rodent (e.g. mouse) and common birds. Field survey finds neither distribution of national key protection wild fauna and flora nor indigenous species. (3) current situation of water loss and soil erosion 14.147km2 has been under control for the water loss and soil erosion by Zhaoyang district in 2003. The total engineering quantity is 257500m3 and labour input is 462000. Zhaoyang district has 512.59km2 of the slight erosion area in 2004. The soil erosion area is 233.74km2, in which: 96.74km2 for slight water loss and soil erosion (41.39% of the total); 95.45km2 for the moderate erosion (40.84% of the total); 27.19km2 for the intensive soil erosion and 14.35km2 for the most intensive soil erosion.

5. ENVIRONMENTAL IMPACT ASSESSMENT

5.1 ANTICIPATED BENEFITS FROM ZTUEP

The implementation of TZUEP will address the environmental infrastructure deficiency issue. It will not only improve urban eco-environment, increase the taste of Chaotong City, bul also reduce pollutants discharging into local river, to the Jingsha River and to upstream of the Three-gorges reservoir. It will lay fundation fo establishing ecological barrier for upstream of the Yangtze River and for regional sustainable development With the completion of the water supply sub-project, it will greatly enlarge the service scope of the urban safe water supply and will increase the qualtiy and safety of the drinking water. 248000 people will be benefited from the efficient centralized safe water supply service in short term as so to improve the urban environment quality and increase the living and health level of the local residents. The protection of drinking sources will also be enhanced. The wastewater sub-project will enlarge service area and population of the urban wastewater collection and treatment. It will significantly reduce the polution to the local water body. Based the design capacity, it’s planned to reduce the following pollutants:

COD1387t/a、BOD949t/a、SS1022t/a、TN73t/a、NH3-N109.5t/a、TP14.6t/a. The construction of WWTP will avoid and reduce the impact of wastewater discharge on the agricutual production by improving the water environment and environment quality and benefit to the Jinsha river basin. The implementation of river rehabilitation subproject will benefit to the elimiating of internal pollution sources accumulated in the river silt, raise the flood protection standard of the river and improve the water quality of Liji River and Tuwei River. The eco-environment of Liji River and Tuwei River will be greatly improved and the ecological system of these rivers be restored. After the project, the river banks with restored raparian vegetation could be a wonderful landscape of Zhaoyang District. In photosynthesis, the vegetation will purify the atmosphere by consuming carbon dioxide and releasing oxygen. The residents of the neighborhood can enjoy the nature with the improvement of the ecological envionment. Thus, the ecological effect of the project is significant.

Figure 5-2 Analysis of the pollutions source of the water distribution network construction

Wastewater: The wastewater in the implementation phase mainly comes from the wastewater of construction and the sewer generated by the site constructors. The construction wastewater contains the slurry in the foundation construction, wash water of the construction material, wash water of the vehicles. The pollutants of this wastewater include mainly silt, petroleum pollutants, etc. these wastewater will be discharged fugitively. To manage and control the construction wastewtaer, the wastewater will be collected to the settlement tank. After proper settlement, this water can be reused as the sprinkling water of the site. Most of the water will be evaporated, only small amount infiltrated into the soil. No water will be discharge directly into the nearby water body. The amount of sewage generated by the constructors should be calculated with maximum number of the site constructors. In another words, the number of constructors for the WSP should be 150 and for the network between Yudong Reservoir and Taiping WSP be 100 (Including concierges). The water

Page 85 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

consumption rate for each constructor worker assumes as 40L/day. To sum up, the total water consumption by the constructors should be 10m3/d. Multipling with the wastewater coefficient, approximately 9m3/d of the sewer by the constructors will be discharged. Similar to urban sewer, the content of the sewer is complex. The quality of

the sewer will assum as COD250mg/L、SS300mg/L、BOD5 150mg/L. The treatment of the sewer could adapt simple process, such as grease trap and sedimentation tank, etc, and then discharge to the ditch. Air Pollution Emission: During the excavation, site preparation period and in the sand warehouse, dust pollution will not be avoidable. Moreover, the transportation will cause dust and exhausted air pollution, and the equipment of construction cause air pollution. Due to many sub-projects of the project, the small scale sites are spread out. The air pollutant generation is limited. Referencing to the measurement of similar projects, the dust concentration of the site normally is between 3 to 10 mg/m3. The dust and the exhausted air by the vehicle, and the air pollution from the construction equipment are unorganized batch discharged. Noise: The noise of the implementation is mainly from the site preparation, excavation, the construction equipments, the transportation vehicles and the construction itself. Soilid Waste: The solid wastes produced during this period mainly are earthwork spoil and building material. Also, the domestic solid wastes generated by the constructors also are a significant source. The WSP and the water distribution and transmission pipleline networks will involve excavation and backfilling, among which the volume of excavation and backfilling of Taiping WSP water transmission pipeline networks are 198720m3 and 155165.59 m3 respectively, and the earthwork spoil will be about 43554.41 m3; the excavation and backfilling of Taiping WSP water distribution network are 197173.2 m3 and 183813.5 m3 respectively, and the surplus earthworks of 13359.7 m3; the excavation and backfilling volume for Qingmen WSP and water distribution network are 71064 m3 and 66248.99 m3, and earthwork spoil of 4815.01 m3. The total volume of earthwork spoil is 61729.12 m3.The volume of domestic waste should be calculated according to the peak number of the site constructors, which are 250. Assuming 1kg solid waste is generated per constructor per day, the daily domestic solid waste generation will be 250kg, which will be cleaned and transported by the environmental sanitation department regularly. After the analysis of the pollution source and the strength of these aspects, the pollution sources and the strengths of pollution during the implemenation phase are listed in the table below.

Figure 5-3 Analysis on pollution sources of WSPs during operation Wastewater: When the water supply sub-project is under operation, the wastewater comes from this sub-project will be the domestic sewer by the workers and the process wastewater of the WSP. 40 people are counted for the Taiping WSP while in Qingmen WSP the number are 25. The capita water consumption is assumed as 120L/day. In this case, the water consumption by the workers will be 4.86 m3/d and 3.00 m3/d for Taiping WSP and Qingmen WSP. Used 0.8 as the wastewater coefficient, the domestic wastewater generation amount will be 3.84 m3/d and 2.4 m3/d. Similar with the urban domestic wastewater, the quality of the domestic wastewater is assumed as COD250mg/L, SS300mg/L and BOD5150mg/L. The wastewater from production is mainly the sludge discharge wasetwater from the settlement tank and the reflush wastewater from the filter. It includes the inpurity from the raw water and the chemical residual from the WSP. The filter will be refrushed once a day. The process wastewater amount usually is about 4% to 8% of the raw water. In this assessment, the value of 5% is used. When the WSPs operate in the short term design capacity, the process wastewater amounts from Taiping WSP and Qingmen WSP are 2500m3/d and 500m3/d. The main pollutant in the wastewater is SS, with the concentration of 80mg/L. in order to save resources and reduce SS pollutant, a sludge discharging tank is designed in the feasibility study to store liquor discharged from settling tank and wastewater from filtration tank back-washing. Liquid at top of the tank will be convoyed to the beginning of the process. Therefore, there would be no discharge of WSP production wastewater. Air Emission: During the operation phase, the distribution tank, settlement tank, sludge thickening tank, sludge storage tank, workshop for sludge drying and the dozing workshop will have odour, with the main pollutant as hypochlorous and ammonia. Noise: During the operation phase, the main noise comes from the mixer equipemnts in the Taiping and Qingmen WSPs, the horizontal centrifugal pump, the lifting machine,

Page 87 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

submerge wastewater pumps etc. in the pumping station and the pressurized pumping station. Solid Waste: The sludge generated from the purity of Taiping and Qingmen WSPs, comes from the settlement tank. The amount is related with the water amount, the quality of raw water and the doze. The sludge can be dried to sludge cake. The amount can be calculated as follows: the dry sludge from Taiping and Qingmen WSPs in short term will be 0.58t/d、0. 07t/d. The total amount is 0.65 t/d. The domestic waste from the workers of the WTPs can be calculated assuming each worker generates 1kg/day. The numbers of worker in Taiping and Qingmen WSPs are 40 and 25 In this case, the domestic wastes generation are 40kg/d and 25kg/d. The total amount is 75kg/d or 27.375 t/a. The sludge will be delivered to WWTP for further drying together with WWTP sludge and then transferred and disposed of at the landfill of Ludian county, and the domestic waste will be treated in the Environmental Sanitation Department. According to the environmental impact assessment and the material balance of the operation phase in three aspects, the pollutants from the operation phase will be as the following table:

5.2.2 MAIN POLLUTION SOURCES OF WASTEWATER SUB-PROJECT

5.2.2.1 Pollution Sources During Construction Pollution sources during construction are firstly identified from the analysis of the sewer netowkr and WWTP construction. Shown in figures below

Figure 5-5 Analysis of the pollutions source of the WWTP construction

Wastewater: The wastewater in the implemenation phase comes from the mixing the sub-projects with construction material, washing, maintaining, wetting the wall and the domestic wastewater from the constructors. Typically, the leakage of the temporary supply pipe and the constant leakage are the wastewater overland flow in site. Moreover, the slurry discharged from the piling foundation work, the groundwater abstracted duing the wet period, etc., are main source of the site wastewater. The amount of construction wastewater is comparatively large but with small amount of domestic wastewater. The main pollutant in this wastewater will be SS. Wastewater will be discharged fugitively and intermittently. Given that during the construction pick time, the maximum number workers of contractor will be 200, at water consumption of 40 l/d.cap, wastewater discharging coe-efficient of 0.9. the volume of domestic wastewater from contractor workers will be 7.2m3/d, the quality of such wastewater is anticipated to be complicated with main pollutants of COD, BOD5, SS, oilds, etc.. Air emission: Dust generated during the implementation phase is discharged unorganized. Most of them form dustfall except few of them becomes floating dust. The dust emission in site is large in amount, the environmental impact not only relating

to the emission amount but also relating to the humidity of atmosphere, speed and direction of wind etc. During the implementation phase, by strengthening the supervision, dust should be reduced by proper construction manner. When transportation and dusty construction, watering is necessary to reduce the floating dust. The tranport vehicles need to be sealed, especially tranportation of soil. The stack of construction material should place properly to reduce the floating dust in site, too. The dust emission is requested to achieve the requirement of unorganized emission in GB16297－1996 “Integrated emission standard of air pollutants”, which is the TSP outside the site can not exceed 1.0 mg／m3. Besides, the heating process of chemical construction material and the construction equipment with diesel fuel, the exhausted air from the tranport vehicles (contains COand NO2) are the main sub-project of the air emission in site. Noise: Noise during construction includes mainly the engineering noise of civil work (i.e. noise from grab, bulldozer). , equipment installation noise and traffic noise from vehicles. The value noise during construction will be 75～100dB(A). Solid Waste: The solid waste in the construction phase mainly consists with the construction solid waste and the domestic waste by the constructors. The construction solid waste includes diposal bricks and rocks, the concrete debris, disposal steel and timber. Also the residual soil and rocks from the reconstruction and extension of pipes are part of the solid waste. According to the engineering quantity listed in the FSR, the quantity of the earthwork spoil during the implementation phase is estimated to be 70100m3. Some of the construction solid wste can be reused. The other solid waste should pile up in the designated location for the treatment by the local environmental sanitation department. With similar characteristic to the urban domestic waste, the domestic solid waste by the constructors should be calculated according to the maximum number of constructor, which are 200 persons. Assuming the daily generation rate of solid waste is1.0 kg/cap, the daily solid waste should be 200 kg. If this part of solid waste can not be treated properly, during the wet season, large amount of leachate will be generated and negatively imapct the water and soil environment of the neighbourhood. Eco-Environment: during pipeline installation, the established trees and greenland will be subject to destruction, the road surface, sideway and established greenland belt will be disturbed. 5.2.2.2 Pollution Sources During Operation Wastewater: In this project, a extension capacity of 20,000 m3/d in wastewater treatment is proposed. After the extension, the capacity of the WWTP is 80,000m3/d. 5 The main pollutants of the wastewater is CODCr、BOD 、SS、ammonial nitrogen and phosphate. Air Emission: The odour from the WWTP will be emitted in the collection system, the treatment system and the sludge treatment system. The main substances to generate

odour are NH3、H2S etc. The odour is unorganizedly discharged. The common substances to generate odour are NH3 and H2S from more to less. The most irritated odour comes from methyl mercaptan. And also the H2S. It was indidated by comparing the odours from Kunming No. WWTP wich was designed and operation under same oxidation ditch process: odour from the treatment process affects mainly the in-plant of WWTP. Outside the WWTP, the strength of odour should not exceed the odour level 1.

Page 90 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Inside the WWTP, the odour sources are spread out so that the discharge concentration is low. Noise: Noise from the wastewater treatment process comes from the wastewater pump, sludge pump, fan, sludge drying workshop. Due to the wastewater pump and sludge pump are submerged, and the fan is located in the fan workshop, the noise is shielded by buildings. In this case, the strength of noise decreased in levels. Solid Waste: Besides the domestic waste from the worker, solid waste produced during the operation phase consists with the following two types: a). residuals: By physical and mechanical means, seperate the solid waste from the wastewater, such as the residual from the screen, the grit from the grit chamber. These are inorganic substance and the production is about 400t/a, which will be transferred and treated at the landfill of Ludian county; b). surplus sludge: commonly is biomass and easy to get stinky. The amount of dry sludge from dewatering machine and after quicklime dying process will be about 2190 t/a with water moisture of 60%, including 265 tones of quicklime. It will be transferred to Ludian sanitary landfill site for disposal. Assuming the number of worker in the WWTP is 33 and the daily domestic solid waste generation rate 0.5kg/d·cap, the daily domestic waste is 16.5 kg, which will commit the local environmental sanitation department for treatment.

5.2.3 MAIN POLLUTION SOURCES OF RIVER REHABILITATION SUB-PROJECT

5.2.3.1 Pollution Sources identification During Construction The river treatment mainly contains dredging, excavation, filling, concrete filling, masonry, greening, etc. Considering the length of the river and the relatively centralized sites, following the princile of proper utilization of the temporary and permanent structures, the construction layout will use centralized and spread out

Page 91 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

combination. The main sites and residence facilities should locate in the scale of land acquisition. The residence building, accessory facilities for construction, mixing workshop for concrete, the stack warehouse of sand and rocks, cement warehouse, steel and timber processing workshop should be closed to the site. According to the local geographic condition along the river bank, find a proper site for the construction layout. And based on the hydrologic characteristic of the river, the river treatment should implement in dry season in principle.

(5) others: river silt drying and disposal potentially generate ecological and health issues, such as land occupation, soil erosion, spread of diseases. Air Emission: Air-born dust from site: When the river is under treatment, the bank will pile up large amount of sand and rocks, sometimes, the disposal soil. Usually, these material will stack there for 15 to 20 days. When the soils are air-drying, under the effect of wind speed, floating dust will be generated. According to the literature statistics, when effective dust protection measure is carrying out, the affect scale of dust can be controlled within 150m. Within 150m, the TSP should be less than 1.0 mg/m3 to achieve the standard. While within 200m, the TSP will drop to 0.39mg/m3. However, if the dust protection measure is not sufficient, within 250m, the dust will affect the environment greatly. Within 250m, the TSP will be about 1.26mg/m3, while within 300m and 450m will be under 0.69mg/m3 and 0.44mg/m3. Dust from vehicles: The exhausted air of the tranport vehicles is related to the vehicle model, fuel and so on. Generally, the environmental impact assessment is to characterize the effect of exhausted air to the environment and based on that present recommendation. During the transport, the environmental impact by the floating dust should take into account of the tranport route. Normally, on the same condition of

Page 92 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

cleanness of the road, faster speed will lead to larger amount of floating dust. On the same speed condition, dirtier road is, more floating dust will be. Exhausted air: During the implementation, all kind of vehicles will come and go to the site, mainly including transport truck, tipping truck, excavator, forklift, bulldozer, etc.

Generally, the content of pollutant emission such as HC、particles、CO、NOX for both gasoline and diesel fuel are listed in the table below:

Table 5-4 pollutant emission from vehicle exhausted gas during construction

Pollutants HC Grain size CO NOX Gasoline Fuel（g/km） 1.23 0.56 5.94 5.26 Diesel Fuel（g/h） 77.8 61.8 161.0 452.0 Characteristics of impact of vehicle exhausted gas on atmosphere: The exhausted gas from the vehicles at construction site are emitted as non-point pollution source. Vehicle exhausted gas emission pipe is relatively low, the scope of diffusion of exhausted gas is rather limited, therefore the impact of vehicle exhausted gas on environment is limited. Vehicles are not in continuously driving condition, the exhausted gas emission duration and emission volume are relative less.. River silts dredging and odour treatment: The odour during construction mainly comes from the silts hauling and silt disposal. The dry beds are used to stack the dredged silt. The silt to be dredged contains large amount of biomass, which will be fermented under anaerobic condition, generating large amount substances with odour such as ammonia and H2S. Even the dredging process, this kind of odour will be emitted. To make sure the level of odour in dredging and silt disposal, Dianchi Lake Caohai is used as an anolog object. The extent of sediment contamination in Caohai, Dianchi lake is much higher than that of Liji and Tuwei River. In this case, the contaminated sediment from Dianchi Lake Caohai should have more smelly substance than that of Liji and Tuwei rivers. Hereby, the level of odour in Dianchi Lake Caohai sediment dredging is used to reflect the odour level of the silt dredging from the rivers. Some odour can be sensed in the sediment dredging in Dianchi Lake Caohai, with level of 2-3 degree. In this case, the dredging and silt drying process will produce similar level of odour. Wastewater during construction The river rehabilitation involves excavation in some locations. When storm occurs, the loose soi excavated will be fluched and flow into surface water body through run off to contaminate the surface water. Two construction methods: a) daming the river section, abstract water out of the damed section for manual dredging, b) mechanical hydralic dredging, connected with pipe convoyance will be adopted during construction. The dredging process will impact the water quality to a certain extent. And also the leakage of oil from the equipment and the oil washing from the equipments by storms will contaminate the surface water to some extent. The processes of washing of sand and stones, the mixing of concrete etc., will generate certain amount of wastewater. The characteristics of such wastewater are the same as the regular construction wastewater, containing high SS with higher pH value. Noise: The noise during construction comes from the equipment and vehicles. Noise from equipment: The equipment used in the implemenation mainly are bulldozer, excavator, loader, crane, concrete mixer, compactor, welding machine, water abstraction machine, piling machine, truck, etc. The operation noise of these equipment will be between 95-120dB(A). Table below listed the detailed noise level.

The volume of the silt dredged from the river will be 154006m3 (90% of water content), considering the unit weight of 1.4t/m3. The weight of dredged silts is about 215608t. The earthwork soil from this sub-project during construction is about 649483.9m3, which will be used for ground preparation in construction of the northern new urban area of Zhaoyang district.

Water and soil erosion: If earth and stone works are implemented in rainy season, or constructed in unstandard way, e.g. excavation, backfill, residual dispoal or sludge disposal at the drying site casually,water and soil erosion, which will be resulted in water and soil erosion. Health: During the implementation, because of the transfer of personnel, malaria, viral hepatitis, phthisic, etc. might be popular and the health of the contructros be threatened. 5.2.3.2 Pollution Sources Analysis During Operation The environmental impact of the project is positive in the regional flood protection, city landscape, aquatic ecology, water environment and social environment. Most of the impact are direct effected. The negative impact of the project is the domestic wastewater and solid waste generated by the daily management personnel. Assuming the number of the management personnel is 10, the produced domestic wastewater is 0.85m3/d, with the main pollutants as COD、BOD、SS and ammonical nitrogen etc, containing

CODcr480mg/L，SS350mg/L，NH3-N30mg/L，and TP7mg/L. This wastewater will be treated by septic tank and discharged to the urban sewer network. The amount of daily domestic solid waste will be 10kg, and the solid waste be collected and treated by the local environmental sanitation department.

5.3 EIA DURING PROJECT CONSTRUCTION

5.3.1 EIA FOR WATER SUPPLY SUB-PROJECT DURING CONSTRUCTION

5.3.1.1 Impact on Air Quality during Construction （1）Analysis for air-born dust during construction During WSPs construction and pipeline installation, main air pollutants will be air-born dust to be generated from excavation, stockpile sites, backfilling, roads on which vehicles pass, spillage during transportation, etc. The occurrence and intensity of dust has close relation with the water content and granular of earth, wind direction and speed, humidity and time of backfill. It has been documented that when dust moisture is 0.5%, its starting wind speed is 4.0m/s. Analysing with local conditions, usually earth cutting and refilling do not cause dusting. But in spring when wind is relatively strong, dusting may occur in small area. Comparing of data shwo the dust concentration at different distances at downwind of construction site at the wind speed of 4.0m/s. please refer to the table below for details.

Table 5-7 Dust concentration at different distances at downwind of construction site

Distance 50m 80m 150m 1m 25m Pollutants 3 3 3 mg/m mg/m mg/m TSP 3.744 1.630 0.785 0.496 0.246 We can see that under unfavorable weather condition, construction dust can exceed national Class II standard within 150m. Impact is limited beyond 150m. The average wind speed is lower than the startiong wind speed of dust of 0.5% water content. There generally earthworks in WSP, pumping station construction will not cause significant dusting. However, when earth stockpile is dry, wind is strong in spring, dusting may occur in certain area and cause adverse impact on ambinet air quality. Enviornmental protect targets with 100 m of Qingmen WSP are listed in table below. When large wind speed occurs, construction dust might be spread and fall onto the surface of nearby irrigation channels and crops, causing adverse imact on water quality and crops’ respiration to a certain extent. Considering that most of the laying of network use open excavation, large amount of backfilling earth and part of spoil will be piling for about 15-20 days. They can cause dusting at starting wind speed when dried. Comparison research shows that under strong wind, dust concentration 1 m downwind of can reach 3mg/m3 and 25m at 1.53mg/m3. TSP exceeds standard at 60m downwind. By analysing environmental sensitive points around proposed engineering of water supply project, impact of dusting during construction period is summarized in the table below:

（2）Analysis for impact of vehicle exhaust gas during construction Many engineering and transporting vehicles will come over the construction site. They are mainly transporting truck, excavator, bulldozer, forklift,etc. The features of vehicle exhaust gas’s impact on atmospheric environment are: With the vehicle moving in the construction site, exhaust gas is a non-point source; With the low exhaust funnel, exhaust gas’s diffusion area is small; Vehicles do not operate continously, so exhaust time and quantity is not limited. In general, in this project, the engineering quantity is small, exhaust gas is small, pipeline is long. With air diffusion and dilution, exhaust gas’s environmental impact is weak, not the main air pollution source. 5.3.1.2 Impact on Water Environment during Construction （1）Analysis for impact on construction wastewater Construction wastewter is generated mainly from sand/stone processing system, concrete mixing system and construction machine washing wastewater. Sand/stone processing wastewater is for material washing. It is of large quantity, with sand content of 4-70kg/m3. It would be wasting water and polluting environment without treatment. Concrete mixing wastewater and concrete pouring wastewater are strong alkali wastewater generated during contrete production. The main pollution indiators are SS, pH of which SS can be eliminated by sedimentation meeting discharge standard. pH is usually above 10. Machine and vehicle washing wastewater contain mainly mud, sand and oil. Their main pollution indicators are SS and oil. （2）Analysis for impact of domestic wastewater from construction workers Domestic wastewater of workers is calculated by the number of workers at peak during construction. It is estimated 250 workers on this project, consuming 6m3/d water per capita. Supposing the discharge coefficient to be 0.9, domestic wastewater discharge is 5.4m3/d. The domestic wastewater of workers is complicated comparing

Page 96 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

with municipal domestic wastewater. Water quality for this wastewater can use : COD250mg/L, SS300mg/L, BOD5 150mg/L. Facilities like grease trap and sedimentation tank can also be used for pre-treatment, and then resued for dedusting watering without discharing into water bodies. Workers who work in urban area can use existing facilities, so the wastewater generated is dispersed in different organizations and collected into the sewerage system. Construction sites of Taiping WSP, Qingmen WSP and pressurized pumping stations should set up dry toilets and solid waste can be used as fertilizer for nearby farmland or vegetation. Domestic wastewater of worker can be used in dedusting sprinkling after grease trap and sedimentation. 5.3.1.3 Estimate and Analysis for Noise Impact during Construction The acoustic pollution of the project comes from construction machines and transporting vehicles. The noise has different characteristics according to phases, locations and operation conditions. This project covers a wide area, the construction of which last over half an year covering WS pipeline laying and the constrution of Taiping WSP, Qingmen WSP and pressurized pumping station. Construction noise has common feature concerning their impact on environment, i.e. generated by construction machines. Main noise sources are bulldozer, excavator, loader, transporting vehicles, etc. the sould level A ranges from 80-100dB (A), most of which above 90dB (A). Boundary acoustic environment evaluation should comply with Construction Site Sound Limit (GB12348-90), Area acoustic envrionment evaluation should comply with Class 1, 2 , 3 and 4a, 4b of Acoustic Environment Quality Standard (GB3096－2008). Mechanical noise is the main source during construction period of water supply sub-project. Without taking into account the impact of house, tree and air, maximum sound level can reach 66dB(A) 50m from construction boundary, 60 dB (A) 100m from construction boundary, 56.5dB (A) 150m from construction boundary. This can meet with noise standard of constrution site boundary in the daytime. Above analysis consider only one machine in operation. When several machines working at the same time, noise level will add by 3-8 dB (A). In reality, considering the barrier effect of house and trees, a decrease of 10dB (A) can be obtained. Integratin all these consitions, noise standard at site boundary 100m from construction site can be respected. The key sensitive points, Majiaying villager group lies 100 m from Qingmen WSP. Construction noise can generally respect limit in daytime but exceed limit at night. Other sensitive objects are over 100m from Qingmen WSP. After distance attenuation, construction noise will not disturb nearby villages in the daytime but will be disturbance at night. The key sensitive point of Taiping WSP, the presure pumping station are listed in table below. These sensitive point within 100 m will be significantly affected by noise. Those sensitive point between 100-200 m will be slightly affected by noise with attenuation of noise along distance. However, night construction might have disterbances to residents in these sensitive points. This sub-project involve more sensitive point when pipelines will be laid along road, passing throut villages. Therefore, noise during construction will couse adverse imact to villages that pipelines pass through, especially at night.

It is indicatd in above table that: noise impact on protected points can be reduced to the accepable level by selecting low-noise construction processes and machines, establishing fence at construction site, and rationally arranging working hours of construction machines. Simultaneous operation of high noisy construction machines at boundary, during nighttime should be banned to avoid noises superposition. 5.3.1.4 Impact analysis of the solid waste during construction 1) Earthwork and stonework Spoils of earthwork and stoneworks will be produced during the construction of water purificaton plant, water distribution and transmission pipeline network, and all of the construction process will have to involve excavation and backfill work, among which the earthwork of excavation and backfill of Taiping WSP and associated water distribution is respectively 197173.2 m3 and 183813.5 m3, and transportation 13359.7 m3; the earthwork of Qingmen WSP and associated water distribution network is excavation 71064m3, backfill 66248.99m3 and transportation 4815.01 m3; the earthwork of Taiping WSP and associated water transmission network is excavation 198720 m3, backfill 155165.59m3 and transportation 43554.41 m3, and the total earthwork spoil of the sub-project will be 61729.12m3. In case of ill-treatment, the large quantity of construction residue will make great impact to the sorrounding environment, urban transportation and city landscape, and some could run into the water distribution pipeline network and resulted in blockage. Therefore, it is suggested that

Page 98 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

construction of civilworks is proceeded with plan, the construction debris must be cleaned up and transferred to appointed places for disposal, dumping to nearby rivers must be prohibited. Currently a great deal of infrastructure construction is ongoing in the north of the Zhaotong urban area with an uneven and low topography. Many places requires to backfill and raise the level of foundations in order to ensure the circulating of drainage system in north area. Spoils earthwork and stone work will be arranged as unified management and unified dispatch by Zhaoyang urban development and construction committee. The project will occupy 0.4km2 of land for tempoary use. It will be used as farmland after the project construction thus the dry surface soil will be used as dry land refilling. According to the information provided by the Zhaoyang urban development and construction committee, Zhaotong avenue is about to construct in the north area, the construction period is basically the same as the project construction. As the current status of Zhaotong avenue is rather low in topography, it’s conservative estimated that the soil for backfilling is about 900000m3. Thus the spoils of earthwork and stoneworks will be considered to be used for the backfilling of Zhaotong avenue. As long as the the temporary stacking protection work based on the water and soil conservation is properly done, the disposed soil and stone will not has big negative impact on the environment. 2) Disused Building Materials Building refuse comes from wasted building materials during construction such as sand/stone, lime, concrete, wood, waste bricks. The quantity is not significant, but without prompt clearance, they may affect the landscape or traffic and cause dusting in windy and dry weather. 3) Domestic solid waste Workers will generate certain amount of domestic refuse. Calculated by the number of workers at peak, i.e. 250 persons generating 1kg DSW per day per capita. The daily DSW generated can be 250kg. Without prompt treatment, DSW will cause insects, odor and disease, resulting in negative environmental impact. 5.3.1.5 Impact on Social Environment WS network constrution will be located mainly along Zhuti Avenue and other roads in the north, which will affect the residents in this area. At the same time, some WS pipeline project related roads will be crossed or excavated, resulting in traffic blockage. Builing material piling will occupy some road surface. Dusting and rainny days will aggravate the traffic problem. However, these impacts will be mitigated with enforced management and disappeared with project completion. WS network construction’s impact on social environment is : land occupation on villagers’ living; inconvenience on residents; dust and noise pollution. These will affect the villagers’ daily life. The 2 WSPs and pressurized pumping station require permanent land acquisition. The related resettlement issues have been written in the unified planning of the northern new urban area construction of Zhaoyang district. The relocation of affected peoples will be settled close to the street in the mid section of northern new urban area where the resettled population could start a new job in third industry. These sites are all within the service scope for the centralized water supply, wastewater collection & treatment, waste collection, waste disposal etc. In all, the resettled EA will be kept to minimum due to the newly installed urban environmental infrastructures for relocated population.

5.3.1.6 Impact on Ecological Environment Land occupation: the WS sub-project will occupy 142.7 mu of land for the establishment of WSPs and presure pump station, and will temporarily borrow 600 mu of land during construction for the establishing camps, construction shortcuts and raw water transmission mains and distribution pipeline installation. Accoring to field survey, the existing land use pattern of such land to be occupied permanently or temporarily are dry farming land, and village residence land. Compensation to these land has been considered in the Ressettlement Action Plan. After the completion of the construction, the borrowed land will be restored as it was. Permanent habitat damage: project construction will cause some unrecoverable damages. For example, original vegetation in the proposed site for WSP will be completed destroyed. Habitat disturbance: part of the project will be constructed in the built area of the town/county. It will therefore cause kinds of disturbance such as noise and ecological change during construction and operation. Temporary habitat disturbance: accidental events during construction will cause disturbance on the ecological environment, which is recoverable, e.g. the revegetation after pipeline laying. Soil damage: Taiping WSP and Qingmen WSP will change completely the vegetation situation in the proposed site. The soil is covered by buildings and treatment structures. Becase of lack of vegetation, soil character will change. Soil condition in the proposed site will change significantly towards fragmentation. Soil erosion: construction impact on soil erosion is represented in: vegetation damaged by excavation. Soil erosion will occur when it rains; temporary land occupation detroys original vegetation and aggravate soil erosion. In case that stock yards and soil piling site are not properly managed, sheet erosion and shallow gully erosion will happen. The project is located in hilly area. The land is flat and exists certain extent of soil erosion. Potential soil erosion may be caused by the excavated spoil and piling materials of Taiping WSP and Qingmen WSP. Exposed soil surface may also cause soil erosion. Impact on Yudong Reservoir water source protected area: the project plans to intake water under the dam of Yudong Reservoir where it is classified as Class 2 protected area. However, water intake has already been constructed with a connector reserved, therefore, the sub-project construction activities will have little impact on water sources protected area of Yudong reservoir.. Nevertheless , if the construction site is located in the protection area, workers may discharge gabbage and wastewater into rivers and affect water quality. Preventive measures has been proposed by EA (see mitigation measures during construciton in Section 8.3.1 of this report) Impact on Dalongdong Spring water source protected area: the proposed project activities will not involve water intake and transmission main construction because there has been a raw water transmission main from Dalongdong Spring to the area near railwaty station. So, the sub-project has no impact on Dalongdong water source protected area. However, as the drinking water source, effective measures for Dalongdong spring protection are not sufficient. It has been highly recommended in the feasibility study and EA to define the entire Dalongdong water body as sanitary protection zone in which protective measures (detailed in migitation measues during operation in Section 8.3.2) should be practised strictly.

5.3.2 EIA FOR WASTEWATER SUB-PROJECT DURING CONSTRUCTION

5.3.2.1 Impact on air quality during construction The main air pollutant during construction is dust from construction and exhaust gas of transporting vehicles. All the activities such as earth excavation, land condition, pipeline laying, pipeline construction and transportation will cause serious dusting. With the help of wind, TSP in ambien air will increase and even exceed the standard value in some area. Similar dust monitoring data shows that construction dust usually is big particulate, most of which will precipitate in the construction site. Few of it will become floating dust, which will affect air quality within 100m. Especially on non-rainny days in dry season when wind is strong, intensity and scope of impact will increase. ① Analysis of impact of WWTP construction on air quality The occurrence and intensity of air-born dust has close relation with the water content and granular of earth, wind direction and speed, humidity and time of earthwork backfills. It has been documented that when dust’s water content is 0.5%, its starting wind speed is 4.0m/s. See table below for the dust concentration at different distances at downwind of construction site.

Table 5-10 Dust concentration at different distances at downwind of construction site Distance 1m 25m 50m 80m 150m Pollutants TSP 3.744 1.630 0.785 0.496 0.246 Main sensitive protection objects around the WWTP are: Fenghuang Village on the southeast, Fenghuang Primary School on the east, Zhaotong Central Logistic Park (under construction) on the north and Tuwei River on the south. Dedusting sprinkling will be used during WWTP construction so impact on these sensitive points are minimum. When wind is strong, dust may precipitate on nearby drain, irrigation trench or vegetation and will influence water quality or vegetation. ② Analysis for the impact of network construction on air quality Network improvement and laying, construction of interceptors will be conducted along roads, where there are many firms and residents. Wind speed and direction can easily be influenced by buildings, local dusting pollution may be serious, which cannot be ignored. During constructioon, exhaust gas is small. In addition, there is widely open space outside of WWTP and the sewer pipelines run long. With air diffusion and dilution, dust has little impact on the ambient environment and the impact from exhaust gas’s is weak, which are not the main air pollution source. 5.3.2.2 Impact on water environment during Construction Wastwater generated during construction is mainly construction wastewater domestic wastewater from contractor staff.. Construction wastewater contains lots of SS such as slurry, sand and cement. which can easily block the rivers. WWTP construction and network excavation produce similar construction wastewater.which has short-term impact on surface water and the impact will disappear when construction terminates. It has no significant impact on surface water.

Page 101 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

5.3.2.3 Estimate and analysis on noise impact during construction Noise during construction comes from construction machines such as bulldozer, excavator, concrete mixer and concrete vibrator whose noise level range between 75-112dB (A). At 10m from sound source, noise from all the contruction machines exceed the limit of site boundary. Even at 100m, part of the construction machines exceed the limit at night. Interciptors are constructed along roads. Some road section are 20-100m away from sensitive points (residential area, schools, hospitals), which will undoubtly be influenced during construction. However, construction noise is random and irregular. Since construction does not last long, noise is of short-term and terminates when construction terminates. 5.3.2.4 Impact of solid Waste during construction Solid waste generated during construction is maily the spoils of earthwork and stonework and building refuse. Wasted building materials include waste bricks, stone, concrete, wood/iron construction waste, and other disposed soil from construction of pipeline. The waste bricks, stone, concrete and wood/iron construction waste will be collected and transported to the specified place for stacking while the disposed soill from construction of pipeline will be disposed by the IA. Based on the BoQ in the FSR, the spoils of earthwrok and stonework are estimated to be 70100m3 in construction period. If spoils were not properly disposed of, it would impact the abminet environment, urban traffic order and landsceap, and potentially stem the sewer pipeline. Recently, the construction of the new Zhaotong Avenue designed for the north new urban area is to be commenced simultaneously with the this project, which need at least 900,000 m3 of backfilling materierls to raise its elevation. The spoils to be generated from this propsed activity can be fully used to backfill the Zhaotong Avenue construction. Therefore spoils from this proposed activity will cause no significant environment impact, provided that the temporary spoil stockpile sites are protected well.

5.3.2.5 Impact on social environment Pipelines to be improved and Pipeline and interceptors to be newly-built will lay out along the roads. This will influence residents of Zhaotong urban area and the activies of units along the roads. Therefore, IA has to coordinate with residents and organize construction hours to minimize the impacts. A passage with enough space should be reserved for passing. At the same time, some roads where sewer pipeline is constructed will be crossed. Excavation will block traffic. Piling of earth and pipes will occupy part of the road surface. Dusting and rainny weather will add to the traffic problems. By proper traffic indicators, traffic and crowd can be well diverged to minimize inconvenience. Therefore, under proper management, these impacts can be mitigated. Being short-term, there impact will disappear when construction terminates. No permanent land acquisition and resettlement is related to the wastewater sub-project construction, thus, there will be no EA to the relocated place for this project.

Page 102 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

5.3.2.6 Impact on ecological environment Excavation and refilling will cause exposed surface during constrution which result in soil erosion. Some soil will be flushed to bottomland or into drainage with storm run-off and will affect the smooth discharge. WWTP is constructed on reserved vacant land. The land of project is flat so with soil conservation meaures, soil erosion can be mitigated. Temporary occupied land should be recovered instantly . Soil erosion during construction is weak, which will not cause significant impact on ambien environment. By solidified cement road surface and vegenation zones, soil conservation will be improved comparing to pre-construction level.

5.3.3 EIA OF RIVER REHABILITATION SUB-PROJECT DURING CONSTRUCTION

5.3.3.1 Impact on Ambient Air Quality （1）Air-born dust The main air pollutant during construction is air-born dust, which occurs in the activities such as building demolition, earth refilling, foundataion excavation as well as tranport and piling of building materials and construction. Dust is diffused on the construction site and surrounding area and transferred into water with rainfall run-off. In dry season when wind is strong, dusting above construction site can seriously deteriorate air quality. Dusting quantiy is the function of a bunch of factors and is difficult to determine. We use analogy method to analyse air pollution. Beijing Environmental Protection Science and Research Institute used to monitor dust of 7 construction sites, at wind speed of 2.4m/s. The monitoirng data show that: Construction site generate serious air-born dust. At the wind speed of 2.4m/s, TSP concentration is 1.5-2.3 times that of the refence point at upwind, 1.88 times on average, i.e. 1.4-2.5 times of the ambient air standard, 1.98 times of average value. The influenced area of construction air-born dust covers 150 m at the downwind. Average TSP concentration in the affected area is 0.491 mg/m3, 1.5 times the reference point at upwind, 1.6 times the ambient air standard. According to monitoring data, near-surface dust concentration is 0.5-12mg/m3. In strong wind seasons, particulate will go with the wind resulting in heavy pollution near the construction site. Near-surface dust concentration near the construction site will exceed (1-40 times) the daily average value of Class II of Ambien Air Quality Standard (GB3096-1996). Dusting in construction are mostly big particulates. Most of them will precipitate in the construction site. Few of them will float to within 150m downwind of the site. According to the distribution of concerning points around, there are lots of residential points and living facilities within 150m from the river banks, where sensitive points are also concentrated. Environmental impact during construction is inevitable. To sum up, production of dust during construction is related to construction method, soil humidity and climatic conditions. High mechanisation will produce less dust. High soil humidity can reduce dust emission. Dust production in rainny and dry seasons is very different. Wind spead can also be an important factor. Therefore, there many uncertain factors on environment. However, with proper measures, their pollution can be minimized. As short-term construction, dust pollution will disappear with construction termination. （2）Mechanical exhaust gas

Page 103 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Construction machines and vehicles produce exhaust gas containing CO, CxHy, etc. The relatively broad construction area, small exhaust emission and high average wind speed will favor the diffusion of exhaust gas so that their pollution on air quality is limited. （3）Odor from river silt dredging Odor is generated during silt dredging and transportation, its intensity is related to its composition, content, way of removal, transport and disposal. The quantity is difficult to determine. Analogy method was used to analyse odor pollution on air. ——Analysis of odor from silt dredging River silt contains large amount of organic matters, the fermentation of which generate odours substances such as NH3, H2S, etc. The odor will be released during dredging. Comparing with the dredging in Caihai of Dian Lake in Kunming, Yunnan, there is only slight smell, at the intensity of grade 2-3. Therefore, odor is weak during river silt dredging, which will not have significant impact on environment. ——Analysis of odor from silt drying sites Dredged silt contains certain water. It does not generate dusting pollutant. Silt contains large amount of organic matters whose fermentation will generate lots of odourous substances such as NH3, H2S, etc. Dredging will stir silts and release odor and aggravate odor at the site. Comparing with the EIA result of dredging project in Caohai of Dian Lake, odor intensity is grade 2-3, maximum grade 4. Odor’s influence ranges within 100m and is more serious at downwind. When dredged silt is transported to drying site, release of odor is similar to dredging, which can be sensed by on-site staff. After piling for some time, after water/silt separation, odor intensity will decrease. Fields surveys have been conducted by specialists of EA and FS, according to the location of drying site. Influenced population is concentrated in Jizhong Village, Jiupu Town Tucheng Village, Shuiping Village, Heinidi Village, Fenghuang Village, Shuitangba Village No.6 Community, Nanwenquan Community. The nearest village from drying site is Shuiping Village, 100m west of 3# drying site. Since the average wind direction is northeast, Shuiping Village will be influenced, but of short-term (about 3 months) and terminates with the removal of sediment. Based on analogy, the silt drying process in the Daqing river silts drying site constructed and managed by Kunming Dian Lake Management Bureau is similar to this project. The silt drying volume in Daqing river silts drying site is 76000m3 and 20m away form the residential area. They didn’t receive any complains from the nearby residents. From the above we can see the odor during the silts disposal can be controlled by measures and management. The analysis shows that odor at silt disposal site is short-term influence. The impact of odor on the ambient enviornment will be minimized by using lime, management strengthening, soil coverage, greening. 5.3.3.2 Impact on water environment during construction （1）Impact of construction wastewater during construction The main pollutants is SS and oil from slurry of excavation, water from sand gravel processing, building materials washing water, vehicle washing water during the project construction. According to the features of river rehabilitation and experiences from other projects. sand gravel processing system will generate 5m3/d of sand gravel mixing wastewater.

Page 104 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Main pollutant is SS at concentration above 500mg/L, 20,000mg/L at peak. Wastewater recycling treatment system of sand gravel processing wastewater was not considered in the FSR, but required in this CEA that contruction contractor should construct sand gravel processing wastewater treatment tank to settle and recycle wastewater and reduce SS discharged into Liji River and Tuwei River. Other wastewater produced in construction would be used for the purpose of dust cleaning after collection and sediment, which will be largely evaporated and only a small portion being absored to earth with little impact to water environment. （2）Impact of domestic wastewater from construction workers There are not many workers during construction period so wastewater discharge is not big. Project sites are mostly located in Zhaoton urban area. Most workers come from urban area or nearby villages so no concentrated constuction camp will be built. From the view of the whole city, there is no additional domestic wastewater discharge. Wastewater will be collected by existing sewerage system. Local water environmental impact is little. （3）Impact of stormwater run-off on surface water during construction Project construction has to excavate. Building materials like gravel and sand will be piled on the site. In rainny days, exposed surface earth and powdery materials will be easily brushed away with rainfall into surface water. Project is located in built area where drainage system is quite complete. Earth containing runoff will flow into sewerage system that will not only influence the sewerage system but also receiving water body. Therefore, project construction should avoid rainny seasons. Control the inflow/outflow of materials to reduce on-site storage and building a temporary construction wastewater sedimentation tank to treat wastewater before discharge is required. Under proper conditions, this part of wastewater will not have significant impact on surface water. （4）Impact of mechanical oil on surface water All kinds of mechanical fuel and lubricant will have leakage problem. This part of oil can easily be flushed into Liji River and Tuwei River and generate oily wastewater. The management of project construction and mechanical maintenance should be strengthened. In addition, the machines should be covered in rainny days. With above measures, oily wastewater discharged into Liji River and Tuwei River can be reduced. Considering the short duration of construction, this part of wastewater will not have significant impact on surface water. （5）Impact of river silt dredging River silt dredging will increase SS and heavy metal concentration at construction points and nearby aquatic area, which will affect downstream water quality. Impact of SS: experience in river dredging shows that local SS concentration will increase by dredging, however it could be reduced by dilution and sedimentation. SS increase is very weak at the 500m outside the downstream of construction point. On the other hand, river sections to be dredged is characterised by invertebrate benthos ecosystem with nearly no fish and macrophate. Such ecosystem is not sensitive to the increase of SS, thus increased SS during dredging will not significantly imact water environment. Impact of heavy metals: most pollutants entered into natural water body will accumulate and form a layer containing all kinds of pollutants, which will be flushed and refloat under certain flow speed and turbulance. Large quantity of pollutant will be

Page 105 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT released again resulting in secondary pollution. This is the main reason causing the impact on the water quality after the control of external pollution. Before dredging, heavey metals contents in silt have reaches their saturation status, while during the silt dredging, the original equilibrium between heavey metals contants in silt and concentration in water will be disturbed. Heavey metal will release from silt into water colume, and thus will impact water quality. According to the monitoring result of leaching test on sludge of Liji River and Tuwei River. Heavy metal concentration in the leachate has reached Class I of Integrated Wastewater Discharge Standard. The Surface Water Aquatic Environment Functional Zoning of Yunnan defines the Zhaolu River, Tuwei River and Dongmen River as Class IV aquatic protection area, mainly for industrial use. During the sludge dredging, released heavy metals by slurry stirring will not have significant impact on Liji River and Tuwei River. （6）Impact on groundwater environment The project is located in the Zhaoyang district. The stratum is rather complete in the project area. the stratum is exposed from cambrian system to quaternary system. The permeable layer: pore permeable lay is mainly the new diluvial layer of quaternary system. The permeable coefficient is 1.1×10-4—1.1×10-3cm/s, which is medium pemeability; cranny permeable layer: lower permian Liangshan strongly weathered sand-rock, mudstone, muddy siltstone, quartz Sandstone, and limestone. The permerable ratio is q＜20.0（Lu）with weak-medium permerability. Waterproof layer: it is lower permian Liangshan weakly weathered sand-rock with less development and closed joint fissures. It ‘s relative waterproof layer. The underground water beneath the project area has bilayer structure, the shallow layer is formed mainly by spring water, the deep layer is deep-seated karstic water that is hard to exploitate. The project is located on the side of Liji River and Tuwei River. No deep excavation. The construction will not affect groundwater. The sludge drying site proposed in FSR is now a farmland, the downstream of which has no water source or important eco-protection zone or sensitive zone. Sludge will be naturally dried. Structure of drying site is: the bottom will be laid with an impermeable layer (300mm thick soil), above which will be a filtering layer (300mm thick layer of big slag or gravel); temporary water drainage blind ditch is set in the middle. Filtrate is collected and discharged into river. Impact on groundwater is limited and of short-term (about 3 months), which terminates when sludge is removed, no significant impact on groundwater. When abnormal situation occurs and impermeable layer is damaged, sludge leaks, shallow groundwater will be affected. With prompt treatment, impact can be minimized with no impact on deep groundwater. Since the Sub-project is at the FSR stage and the detail design for sugdge drying site is yet to be arranged, the EIA would require that it would be necessary for design to arrange rational location for underneath drainage pipeline according to the layout of sludge drying site, with the consideration of leachate drainage through the underneath pipeline. （7）Impact of silt drying pits on aquatic environment Certain amount of leachate will be produced during silt drying, then collected and discharged into rivers. Monitoring result shows that concentration of Ag, Ni, Pi, Cr6+, total Hg, fluoride, cyanide, As, Be, Se, Total Ge, Total Cr, Pb, Zn, Cu and pH have meet with Class I of Integrated Wastewater Discharge Standard. Leachate pollution on Tuwei River and Liji River is quite limited.

Page 106 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Idealy, silt dredging will be arranged in dry seasons. Furthermore, in the feasibility study design, the dry pits will be provided with impermeable layer, installed with stormwater drainage ditches to prevent increased leachate in storm or long-period of raining events, and thus, if the construction falls on the unfavorable weather condition, the impact of silt drying pits on water environment will not be significant and wil not worsen water quality in Liji and Tuwei Rivers. Since there’s no mointoirng of COD or BOD in the silt leachate, and no quantitative analysis could be conducted on the river water quality impact by COD discharge from the silt leachate from drying site, qualitative analysis has been adopted to find out the impact to river water quality by COD of the leachate. Based on the routine monitoring data from Zhaotong Envornment Monitoring Station, Liji River and Tuwei River are polluted water environment and the water quality presently is respectively worse than Class V and Class V, which has been failed to fulfil the eco-function demand (Class IV water body). The discharge of silt leachate from the drying site is a short-term phenomenon, which will be terminated after the silt dried. Besides, cleanup of the river silt will radically eliminate the release of pollutants from riverbed siltation, and the heavy metal and COD contained in silt will not spread into water directly, which will benefit to water quality improvement for Liji River and Tuwei River. From a long term perspective, the implementation of the Sub-project wil benefit the improvement of river quality. 5.3.3.3 Estimate and Analysis of Noise Impact during Construction （1）Analysis of construction noise source Noise of construction project comes from mechanical equipment (digger, bulldozer, etc.) and vehicles(carrier, truck mixer, etc.) Construction noise are phased, temporary and flexible. Different equipment generate different noise. When several mechanical equipment works simultaneously, Noise will overlay. Comparison research shows that overlaied noise can increase by 3-8dB. （2）Estimate and analysis of construction noise While considering the environmental impact of project, consider only the attenuated noise at different distances from point source along distance and calculate the contribution value of noise source on nearby sensitive points, then analyse these values. The calculation of noise value is :：

LA（r）=LAref（ro）-(Adiv+Abar+Aatm+Aexc)

In the forumla ：LA（r）—— sound level A at distance of r from sound source, dB；

LAref（ro）—— Sound level A at reference position ro, dB；

Adiv——Sound level A attenuation cause by geometric divegence,dB ;

Adiv=20lg（r/ ro）

Abar——Sound level A attenuation cause by obstacles , here it equals 0；

Aatm——Sound level A attenuation caused by air absorption, dB，

Aatm=α(r/ro)/100, α=1.142；

Aexc——Additionsal sound level A attenuation,dB, Aexc=5lg(r/ro)。 Estimated results by using above forumla are shown in table below.

At night, noise reaches the limit of construction site boundary at the distance of 300m, with heavier impact on surrounding environment and sensitive senser. Therefore, in the daytime impact of construction machine’s noise concentrate within the distance of 100m. The key protection objects of current project are residential areas and schools (shown in table below).

From the estimated results, the most influential objects are pile driver, trucks and tank trucks. The max noise comes from pile driver. It’s reported during the piling, the noise leve is 106.0-115.0dB (A) while the noise from cast-in-place pile driver is 86.0 dB (A). it’s recommended to use cast-in-place pile driver during the construction. hydraulic machinery is stable comparing fuel machinery and the noise produced by hydraulic machinery is 10dB(A) lower than the one produced by fuel machinery. Thus, it’s recommended to use low noise construction machinery and process while pile driving so as to mitigate the impact on the school and residence area near the river. The noise impact is large during the night. It’s forbidden to conduct filing at night. Sludge loading points are located on the riverbank roads. With short loading time, by proper arrangement, the noise on surrounding environment is acceptable. Tuwei River and Liji River travel through the central urban area, which will have impact on surroundings. However, by proper measures and strict management, construction noise can be mitigated. The impact could be acceptable. Therefore, IA should choose low-noise equipment and advanced process and arrange the the working time of machines properly. Simutanous operation of high-noise machines is strictly prohibited to avoid noise overlay, especially for loader and excavator. For different construction phases, noise control should strictly follow Noise Limit for Construction Site (GB12523-90) to reduce the impact of noise on surrounding environment. The EIA started during FS phase, when the location of sand gravel mixing site had not yet clear, other construction sites had no specific planning or clear location. Detailed protection objectives were not determined. It is difficult to estimate the impact of construction noise on sensitive objects. In this section, with the estimate result in table below, on the premise that noise meets standard, attenuation distance for noise is proposed: construction machines have to operation 100m away from noise sensitive point, and no operation of high noise equipment at night, thus to ensure the noise control of sensitive objects such as residential area and schools. In general, the impact of mechanical noise during construction period is weak. Nearby residents will be the one that most directly influenced. However, these impacts are temporary and will disappear with construction completion. Strict implementation of the environmental protection plan proposed by this report will be helpful in mitigating these impacts.

Page 109 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

（2）Analysis on the impact of traffic noise Transporting vehicles during construction period will influence the acoustic sensitive objects. These vehicles will use existing route in the urban area, which have fully considered the protection of nearby sensitive objects and equiped with mitigation measures. During project construction, traffic flow will increase. But from the view of the quantity of engineering, the increase is quite limited, within the scope of design traffic flow. It will not have significant impact on sensitive objects. Transporting vehicles should avoid passing the area where residential area is concentrated or high noise sensitive areas (school, hospital) to reduce the noise impact of transporting vehicles. Transportation of vehicles should avoid rush hours. Above measures can mitigate impact of transportation on ambien environment. 5.3.3.4 Solid waste impact during construction The solid waste generated during construction are mainly spoils of earthwork and stonework, building refuse and dredged sludge. To develop the north new urban area, the ground elevation increase and leveling will be taken place during October 2010 to December 2012 with will be in parallel with the river rehabilitation sub-project and also be managed by ZUIDC. The maximum distance between river rehabilitation activities and north new urban development area is within 10 km. Spoil of earthwork under this project can be directly hauled to the groud leveling sites at north new urban area directly, thus, there is no need to set up a stockpile site for spoils. （1）Earthwork and stonework There will be excavated earthwork and stonework, backfilling of earthwork and stonework during the construction of river rehabilitation. According to the design small quantity of earthwork residue will be generated and IA will use them for ground perparation in the construction of northern part of Zhaoyang District. Thus has little impact on the environment （2）Building refuse Project building refuse comes from the building refuse and wasted building materials during demolition. Building refuse from demolition are mainly: broken brickes, cement, wood, sand, gravel, stone, stone ballast, etc. It is projected to conduct classified centralized collection and sell them to professional collectors. Most of building refuse are recyclable resource after classification, selection and crushing such as wasted steel bars and auxiliary components. After separation and remelt, they can be forged into different type of steel. Wasted bamboo and wood can be processed into artificial wood. After grinding brick, stone and concrete can be produced into different types of brick. Project will strictly follow the Decree No. 139 Municipal Building Refuse Management Regulations of the Ministry of Construction, PRC that it is prohibited to mix building refuse into domestic refuse and prohibited to set up unauthorized field to accept building refuse. IA will eliminate promptly the building refuse generated during construction and have it disposed by respecting local sanitation authority. Contractor should not have the refuse transported by unauthorized person or organization. （3）dredged silts ----Analysis of the impact of silts use for on green land on soil environment

Page 110 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

According to the above analysis, the quantity of sludge for green land use will be 87000m3，Which is about 21750 m3 after dried to 70% of water moisture. According to the data provided by construction organization, silts for green land use purpose would be used for virescence on both sides of the river. According to FS data, the virescence area on both sides of river is about 125209m2, and earth demand about 37562.7m3. The sludge from rivers outside of town is about 21750 m3, which could be totally received by virescence use. Silts for green land use comes mostly from the rivers outside of town, which will be laid on ground surface and form a thick layer of earth. The following table describes the suitability of the earth for forestation based on grade III of the Soil Environment Quality Standard (GB15618-1995).

The above table tells that the heavy metal content in silts for green land use is far lower than the limit of Grade III of Soil Environment Quality Standard (GB15618-1995), which could not noly meet the requirement for forestry land, but also turning waste to usefull resources. In the mean time, it helps to release the unnecessary presure of sanitatary landfill site under construction, enabling the sanitary landfill site serving for longer period. ----Enviornment Impact Analysis of silt landfill disposal The leaching test of the river silts has shown that the silts to be dredged is not hazardous waste. For the sake of safety and to ensure that silts to be dredged from the urban section of the rivers courses do not impac environment, It’s planned to haul the dried silts to Ludian landfill site for disposal. 5.3.3.5 Impact of construction vibration The pile driving is needed in the river rehabilitation sub-project.The project is in the stage of FS at present. This CEA requires the project adopting vibrator pile sinking cast-in-place pile when carrying out pile driving in river rehabilitation of urban river section of Wukong Bridge, Banban Bridge, Yangjia Stone Bridge and Zengjia Stone Bridge as well as Shengli Bridge. The process of vibrator pile sinking cast-in-place pile is a kind of bushing hole-forming bored pile. It sinks the pile shoe with reinforce concrete or steel sleeve with valve pile shoe into the earth, and pour concrete when drawing the pile. If reinforced type is used, the reinforcement cage should be installed before pouring concrete. Vibration produced by vibration exciter is used when sinking pile and drawing pile. This is why the process is called vibrator pile sinking cast-in-place pile. This process uses hammer or vibratory impact rammer for pile sinking. Before construction, install the pile machine and close the valve at the end of pile or slip the valve over the pile shoe. Release the casing slowly and sink it into the

Page 111 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

earth. The vibration exciter could be turned on and the pile sinking begins when these preparations are finished. Frictional resistance between pile and earth would become smaller and smaller when the vibration begins. Use the hammer pressing the pile casing then the casing could sink into the earth. The main pollutant of this construction is the vibration. However, the vibration level is smaller than vibration of traditional pile driving. The construction vibration would not have big impact on ambient environment if the construction time is reasonable. Vibration sources are alone the river during the project construction, in which, Wanghailou is 100m from Tuwei river. Implementation unit and engineering team should study the regulations on the protection of cultural relics and the Law of the Peoples Republic of China on the Protection of Cultural Relics. The cultural relics and heritage should be protected in abidance with the Law. Although Wukong Bridge, Banban Bridge, Yangjia Stone Bridge, Zengjia Stone Bridge and Shengli Bridge above Liji River are not historical relics, it is also necessary to protect the five bridges in the process of construction. 5.3.3.6 Impact on social environment （1）Land acquisition and resettlement Permanent land acquisition in the river rehabilitation sub-project will be 107.62mu (13.59mu of farmland and 94.03mu of dry land). The land for temporary use is 252.41mu. the permanent land acquisition will mainly used for enlarging the water course. This part of land currently is farmland for vegetable and paddy. The land for temporary use is mainly for constructing site, sludge drying site and the land will be returned as it was used before the construction at the completion of project. During construction, some land will be temporary borrowed as silt drying site, construction site and temporary roads access to the construction site. The requirement on the use pattern of such temporary land, recovery of temporary land, the compensation standard of temporary land use will be specified in the contracts to be signed between the PO/IA and contractors. In order to reduce the impact of temporary land use for road excavation on environment and local residents, the DIs are requested to take full consideration of the siting of temoprary land use, the construction method and the land reclmation after the project completion in the design.. The river rehabilitation is linear engineering with little impact scope. Based on the reply and approval of the “resettlement compensation and relocation of the land expropriated farmers in the Longquan area of Zhaotong urban area from Zhaoyang district government (Zhaoquzhengfu [2009]4)”, the farmer that lost half/above half of his land will be properly relocated in the planned relocation site. The persons/enterprises to be resettled by the project have been incorporated into the plan for resettlement of the new urban area development in the north part. The places for resettling the project afftected persons/enterprises will be located at middle section of the north new urban area, close to avenues to enable them to be find employment opporunities in the service industry. These area are within the service areas of municipal water supply, sewerage, solid waste management systems. Therefore,. the impact of resettlement on ambient environment would be rather small. By analysis, there is little land aquisition impact on the majority of farmers. The impact could be minimized by developing practical RAP

Page 112 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

（2）Traffic congestion The water course of river rehabilitation sub-project goes across main roads in the city, which have heavy traffic. Project construction will affect traffic. Land occupied by earth piling and building materials will make the roads narrow. Traffic can be in disorder, which will have significant impact on residential life. However, such impact is short-term, it will disappear with construction completion. During project construction, it’s required to install protective structure in construction area, to inform nearby residents before construction to obtain their understanding and use alternative route during construction to minimize impact on residential daily life and to set obvious indicators at the affected road sections. It’s also suggested to clearly determine construction area and avoid influencing the normal use of roads. Implementation unit should fully consider traffic problems and design temporary detour when construction is conducted near heavy-traffic roads. It’s required to be constructed in sections and complete the exavation, refilling and repair work in shortest time. (3) impact on logistic & transportation Transportation of raw/auxiliary materials, construction refuse and solid waste will add to the traffic load of Zhaoyang District and affect the livelihood of residents. However, the quantity to be transported is limited during construction: stone and other auxiliary materials (input) and silt and building refuse (output). By choosing a suitable route and avoiding rush hours for transportation, the impact of project transportation on urban traffic can be reduced. There has been an initial road network in the project area with rather convenient transportation donditions. As long as the routes for hauling-in raw/auxiliary materials and hauling-out spoils and dried silts be selected proporly and arranged to avoid the rush hours, the impact on transportation can be mitigated. The silts dredged from river sections outside urban area will be hauled by sealed trucks to avoid potential secondary pollution on roads. The silts to be dredged from river sections in the urban area will be sealed convoyed by pipeline from the dredging site to drying pits to avoid spillage and secondary pollution. （3）Impact on landscape The proposed project covers long distance and large amount of construction, which will have impact on some local landscape such as damaging greening area and exposomg land. Therefore it is suggested to: conduct centralized construction and cover the site while constructing; reasonable arrangements for the greening during the construction phase by “greening while constructing” to ensure the ecoenvironment benefit could be relected as soon as possible and reduce the impact on landscape during the construction. （4）Impact on cultural relics As indicated in section 4.1.3 of this report, Wanghailou is the only cultural relic at municipal level, located 100m to the west of the Tuwei River that is subject to indirect impact from the sub-project. In addition the Wukong Bridge, Banban Bridge, Yangjia Stone Bridge, Zenjia Stone Bridge, Shengli Bridge were built in 1950’s with traditional Chinese architecture style They are of commemorative significance. Based on the consultation oppinions from local cultural relics administration, Wanghailou is a cultural relic at municipal level, its protection diameter is 30m, and construction control diameter of 60m.

Page 113 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

The project is about 100m to Wanghailou. Construction’s impact on Wanghailou is mainly the mechanical vibration and dust. During the construction, it’s required to appoint specific personnel to inspect and protect Wanghailou, use hydraulic pressure or static pressure equipement to reduce viberation as far as possible, and also shelter Wanghailou with plastic fabric. In order to protect Wanghailou and chance found valuable historic relics during the construction, Referring to Zhaoyang District Culture and Sports Bureau has brought forward its opinons EA has proposed mitigation measues which are included in the EMP By taking the above measures, the impact of construction period to Wanghailou will be low and will be terminated as soon as the completion of construction. 5.3.3.7 Impact on Ecological Environment （1）Main project construction Impact on terraneous ecology: The project implementation area is mainly located in constructed area of Zhaoyang District, Zhaotong Municipality. it’s urban ecosystem. Project construction will take up a certain amount of greening land and make certain change on the integrity of the urban ecosystem. However, considering the short duration of construction and with the objective of improving urban landscape of the river side, project will finally be in favor of urban ecosystem. Environment impact on urban eco-system is short and reversible. Impact on aquatic ecology During project implementation, disturance and damage on current aquatic eco-system caused by river dredging, slope and river bank protection will affect the stability of eco-system. However, Liji River and Tuwei River have large amount of sludge, fish has disappeared in the urban section, other living beings such as plankton and aqua-plant are rare. Invertebrates in the sludge are mainly earth worm. This forms typical eco-system characterized by benthos. During construction, the re-suspension of fine sand will create a turbidity plume belt around the dredging site, and thus create to a certain extent impact on aquatic ecology, especially on benthos. During project impelmentation, river sludge will be dredged which will change the conditions of river eco-system. However, such changes will favor the formation of a better eco-system which will change the singularity of eco-system and enrich river landscape. On the other hand, sewerage system in Zhaoyang District of Zhaotong Municipality is not complete with low collection rate. Some illegal buildings are built near the river bank. Interception trunks along Tuwei River and Liji River are not completed. Some sewerage outfalls discharge the wastewater into the rivers, resulting in serious pollution in the urban rivers. Some sections have become drainage ditch during dry seasons. River silt accumulate yearly, neither fish nor aqua-plant can survive in the rivers. Research on river pollution shows that the main causes for the river pollution are external and internal pollutions. In many rivers while external pollution have been significantly reduced by river rehabilitation, the water quality is not significant improved. This is because of the continuous release of pollutants from river silt. River silt dredging is not only an efficient method to enhance flood control, but also thorough way to eliminate internal pollution. In general, the project construction’s impact on eco-system is acceptable. （2）Impact of silt drying sites

Page 114 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Silt drying sites has no primitive vegetation, current secondary herbs . Farmland in the site grow rice, corn, vegetables, etcl condition. In general, eco-system in the site has significant agricultural characters and some extent of soil conservation capacity. However, because of frequent human activities, its soil conservation capacity is fading and degrading. Poor biodiversity. Habitat without special functions. During construction a total of 4.77 ha. of paddy rice field and dry farmland will be temporarily borrowed as silt drying pits. Establisment of silt drying sites will change completely the eco-environment of the sites. Vegetation on these borrowed pits are farming crops such as corn, vegetable which are very common. Habitat for plant and crops will be temporarily destroyed by sludge piling. But living being in the site will not extinguish. Soil conservation capacity in the site is degrading. Eco-function is very weak. The drying pits will be installed with earthern drainage diteches and a sand-trap tank to control erosion. After the completion of the construction, drying pits will be restored for farming. Therefore the construction of drying site will not accelerate the degration of eco-environment. Moreover, the impact is of short-term (about 3 months) and will terminated after removal of sludge. In general, the impact of silt disposal site on eco-environment is acceptable. 5.3.3.8 Analysis on the impact of soil erosion during construction soil erosion increased by subproject During construction, because of strip of topsoil the disturbance of construction activities, soil erosion will be increased as calculated in table below is no countermeasues would be taken.

The existing erosion intensity in the project area is 1378.17 t/km2.a, belonging to light erosion area. If no water conservacy actions are taken, erosion intensity will be increased which is unfavorable to local eco-enviornment protection. Impact on soil and economy; incremental soil erosion induced by the subproject during construction will be silt on river which is harmfull to downstream. Impact to safe operation of rivers: soil erosion is closely related to the safe of river slope and embankment. Construction disturbance to ground will induce erosion and harmful to the safety operation of rivers. Acceleration of soil fertility losess: organic matter in soil will lose with the erosion of soil duirng construction disturbance. Soil structure will also be distroyed. Soil condition will be deteriorated. Reduced water enviornmental function, even deterioration of environment.

Distruction to existing natural landscape.

5.4 ENVIRONMENT IMPACT ASSESSMENT DURING PROJECT OPERATION

5.4.1 ENVIRONMNET IMPACT ASSESSMNET OF WATER SUPPLY SUB-PROJECT DURING OPERATION

5.4.1.1 Environment impact analysis on air quality The treatment facilities in WSP are open. The peculiar smell of raw water could be smelt in the air and has certain impact on the nearby environment. This impact is depended on the water quantity and water quality. In order to find out the influence degree of peculiar smell, special survey has been made in other city of China, i.e, Shanghai. The survey result statistics show that, peculiar smell could be smelt in 20m in downwind direction. If people is standing 50 meter away from the facility, peculiar smell would not be smelt. Because the treatment capacity of this project is not big and the quality of raw water is good, the impact of peculiar smell is very small. The EA recommend to install ventilation system in the chlorination house to safeguard operators. 5.4.1.2 Environment impact analysis on water quality When this project is finished, the wastewater discharged are mainly domestic wastewater of water treatment plant and process wastewater. According to the pollution analysis of this project, the domestic wastewater quantity of Taiping WSP is 3.84 m3/d and processs wastewater quantity is 2500m3/d. Domestic wastewater quantity of Qingmen WSP is 2.40 m3/d and processs wastewater quantity is 500m3/d. to save resources and reduce SS pollution, the feasibility study design has considered a sluddge discharging regulation tank to store and further regulating slurry from sedimentation tank and back-washing water, where the supernatant fluid will return to the beginning to treatment process, thus no production wastewater will be discharged. FSR of this project recommends that all the wastewater of these two WSPs would be sent to municipal wastewater network and Zhaotong (WWTP) finally. Because the main pollutant of process wastewater is Sustained Solid (SS), supernatant of proecss wastewater could be used as backwashing water of filter tank. Water from sedimentation tank and backwashing water from filter tank could be sent to distribution well for reuse. So, we recommend that the production wastewater could be reused and the domestic wastewater could be discharged into municipal wastewater network for treatment. Extension project of Zhaotong WWTP is ongoing. The treatment capacity of this WWTP is 60,000 t/a at present. And the treatment capacity after extension project would be 80,000 t/s. Treatment process is biological treatment process which is based on oxdation ditch. The design capacity for related wastewater network in long-term is 180000 m3/d. The domestic wastewater is few and has very small impact on the inflow quantity and water quality. Therefore, the reuse of production wastewater and treatment of domestic wastewater in municipal WWTP is feasible. 5.4.1.3 Noise impact The main noise sources of this project are Taiping WSP, Qingmen WSP and pressurized pumping stations. The noise facilities are roots blowers in WSP and pumps in pumping station. The sound level of root blower is about 105 dB and sound

Page 116 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

level of pump is about 85 dB. This assessment calculates the environment impact of roots blower by using distance-decay model. The formula of this model is:

r WP 20lgLL Δ−−= L r0

In which: Lp—noise level of target point； Lw—noise level in noise source; r—distance between target piont and noise source, m；

r0—distance between monitoring point and noise source, m ᇞL—Decrrement casued by all factors, equal to 3 dB; The caculation result of noise impact is in the following table

Table 5-15 noise impact prediction of WTP

Distance（m） 10 20 50 100 200 250

Impact value（dB） 82 76 68 62 56 51

According to this table, the sound level on day and night would reach the standard only when target point is 250m away from noise source. Therefore, sound insulation and shock absorption measures should be adopted on the room of root blower. By installing root blower in a single room with sound insulation measures and using shock absorption measures, the noise could be reduced by 20dB and compliance distance could be reduced to 50m. Majiaying Village, the nearest environment protection target of Qingmen WSP, is 100 meter away from the WSP. Taoyuan First Village, the nearest environment protection target of Taiping WSP, is 50 meter away from the WSP. These two WSPs has little impact on environment sensitive points nearby. According to “settlement scheme of proposed projects for Zhaotong city new district construction”, the environment protection targets of Taiping WSP, Taoyuan First Village, Taoyuan, Second Village and Taoyuan Third Village all have to be relocated. That means the removal of residents near Taiping WSP is not belonged to this project. 5.4.1.4 Solid waste impact The solid waste of this project is domestic solid waste of staffs on site, sand settling and sludge of WSPs. According to project pollution analysis, solid waste quantity of Taiping WSP is about 40kg/d, quantity of sludge is 0.58t/d. Solid waste quantity of Qingmen WSP is about 25kg/d, quantity of sludge is 0.07t/d. The total solid waste quantity is 75kg/d, i.e.37.375 t/a. Total quantity of sludge is 0.65t/d, i.e. 237.25t/a. Domestic solid waste from WSP will be treated by the local sanitation bureau. sludge will be dewatered by a belt compressor to the moisture of about 75-80%, haulted to WWTP to further dry together with WWTP sludge to the moisture accptable by sanitary landfill site, and then be hauled together with WWTP dewatered and dried sludge to landfill site for final disposal. Solid waste generated in operation will also be treated properly to minimize impact to local environment. 5.4.1.5 Analysis on the impact on water quantity and quality of water sources (1) Analysis for Yudong reservoir

Page 117 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

The proposed water transmission pipeline is to intake water under the dam at flow of 40.2 million m3/a. under the normal reservoir operation condition, this intake flow account for 12.1% of its normal water storage capacity of t 353 million, m3, and 40.7% of its lower storage capacity of 105 million, m3. it is calculated that the workable water in the reservoir will be sufficient enough to ensure water intake volume for this project. It is also analyzed in EA that water intake volume by Taiping WSP, accounts for a very small proportion of water resources captured at the reservoir’s upstream and will not make significant changes to water quality in the reservoir, and downstream of the intake point. (2) Analysis for Dalongdong Srping Dalongdong is one of the important sources of domestic water supply. Its maim function is to urban water supply. It has total storage capacity of 2.313 million m3 , flood control storage capacity of 1.82 million m3 , and dead storage of 6,000 m3 , annual replanish volume is around 8.48 million m3 , including 6.0 million m3 of spring water and 2.48 million m3 of precipitation. The designed annual water supply volume of the reservoir is 7.975 million m3, including 5.475 million m3 of urban water supply and 2.50 million m3, of other supplies to its downstream. Under this water supply sub-project, the first phase of capacity of Qingmen WSP will intake 4.02 million m3/a water from Dalongdong reservoir accounting for 73.4% of the designed urban water supply capacity. However, the long-term capacity of Qingmen WSP has to be supplied by Qingmen Reservoir due to insufficient remaining water in Dalongdong spring. The volume of water intake for the first phase of Qingmen WSP accounts for 47.4% of the annual water replanishment to Dalongdong reservoir, therefore, it will not impact on reservoire’s other water supply to its townstream and will have slight impact on water quality in the reservoir and its downstream.

5.4.2 ENVIRONMENT IMPACT ASSESSMENT OF WASTEWATER SUB-PROJECT DURING OPERATION

5.4.2.1 Environment impact analysis on Air quality The main air pollutant of WWTP in operation period is odor pollutant. The odor of wastewater and sludge come from fine screen, grid chamber, secondary sedimentation tank, sludge dewatering workshop, sludge storage pool and sludge drying site. The main component of these odor pollutants are nitrogen compounds, H2S, CH4, mercaptan and alkyl sulfide which are fugitive emission sources. Odor monioring has been carried out on WWTPs with the same treatment process and same process. The monitoring result is listed in the table below:

Table 5-16 Monitoring result of odor gas in aeration tank Odor gas Aeration tank downwind downwind downwind Class II of GB14 50m 100m 150m 554－93

Ten youths who are smokeless and no drinking do the on-site smell test. When doing the test, the wind direction is northeast, wind speed is 4.5m/s and the temperature is 12°. The odor level are divided into 6 classes. Surveyors would do the smell test in the downwind direction in the distance of 5m, 30m, 50m, 70m, 100m, 200m, and 300m. Similar tests would be implemented at the upwind direction. The survey result is in Table below.

Odor could not be smelt if surveyor stand in more than 300 meter away from the facilities. In the upwind direction, odor could not be smelt in the distance of more than 20 meter. In order to reduce environment impact of odor in WWTP extension project, submerged sype facilities as well as installing wastewater treatment facilities indoor should be adopted as much as possible. Structures which would produce much odor should be centrailized and constructed away from Fenghuang Village and other factories. Plant evergreen arbor as well as shrub around the treatment plant to absorb and isolate odour. Practices in other WWTPs show that odour could be controled in an acceptable area after adopting these measures. According to pollutant discharge standard for urban WWTP (GB18918－2002), green belt and protection distance should be set in urban WWTP. Considering green belt and analysis of similar WWTP, the protection distance of Zhaotong WWTP is 100m. Isolation strip and green protective belt around the WWTP should be constructed. High arbor should be planted in downwind direction and around ptrotection target, so that the odour impact could be controled and reduced. Fenghuang Village locates in southeast of WWTP with a distance of 80 meter. In east of Zhaotong WWTP, there is Fenghuang School. Zhaotong urban south logistics park loactes in north of Zhaotong WWTP. This is an ongoing project which would plant a green belt between WWTP and logistic park. Total area of Zhaotong WWTP is 91200 m2, based on the measurement of existing WWTP setting, the distance between the operation structures and plant boundary is 109 m, while the distance from the plant boundary to Fenhuang Village & Fenghuang Primary School, the nearest points of environment concerns, is 80 ,(seperated by Tuwei River and Zhaolu highway), and to the boundary of the south logistic centre (which under construction with 70 m of greenland buffer zone at this end) is 5 m. These nearest points of environmental concerns have been more than 100 m awary from the operational struction, meeting the requirement of over 100 m protective distance. Furthermore, there have been no any complains from the residents/student of these points to WWTP since its operation. The main structures, such as the oxidation ditch and so on, to be constructed under this proposed activity are to be located at western side the , WWTP closing to No. 213 state highway, the distance of these structures to above mentioned points will be longer than that of the existing structures, and longer than the required protection distance.

5.4.2.2 Environment impact analysis of water quality Receving water body of proposed wastewater sub-project is Tuwei River. The water function of this river is set as industrial water. This river would be protected following Class IV standard of surface water environment quality standard (GB3838－2002). Outflow of WWTP would follow the class I-B standard in the table 1 of Pollutant discharge standard of urban WWTP (GB18918－2002). When proposed project is put into operation, domestic wastewater sub-zones of Qingmen, Taiping , Fenghuang Mountain, and part of the old town at south of Zhaotong Central Urban area would be intercepted and delivered to WWTP for treatment. The waste water after treatment would flow Tuwei River. Zhatotong WWTP adopts oxidation ditch process. This process has got great advancement and application. Existed WWTPs in Zhaotong City all use oxidation ditch process and get rich operation experiences on operation management, equipment supply and staff allocation. So, normal operation of WWTP could be guaranteed. Outflow after treatment could reach relevant standards of Pollutant discharge standard of urban WWTP (GB18918－2002) and has little impact on Tuwei River. Because oxidation ditch process which has a high organic loading and strong capactiy of resisting impact

load was adopted, BOD5 could be reduced by 95％～98％ and CODcr could be reduced by 90～95％. This process also has a high ability of nitrogen and phosphorus removal. Pollutants flowing into Tuwei River would be reduced greatly by using oxidation ditch. The nutrient source which result in water eutrophication would be reduced too. Removal amount of pollutant when WWTP go to operation is listed in following table.

Table 5-19 Removal amount of pollutant Name of pollutant Removal amount before project completion after project completion removal amount COD 1825 438 1387

NH3-N 167.9 58.4 109.5 TP 21.9 7.3 14.6 By comparing the situation analysis before and after project completion, total amount of water pollutant in Zhaotong county would decrease greatly after project completion. The environment quality of Tuwei River and urban river would be improved, including increasement of water environment capacity and water self-purification capability. It would be beneficial to water environment quality protection, public health and investment environment. 5.4.2.3 Environment impact analysis of Noise Noise comes from all pumps and exhausters. The sound level of noise source is about 75～110dB(A). The noise prediction model is: Combined noise level model

n L = （∑10lg10 Li 10） i=1

In which: L——combined noise level of multiple noise source，dB(A)；

Li——noise level of one noise source, dB(A)。

Page 120 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

sound energy attenuation model = LL − )/lg(20 − ΔLrr rr 0 )()( 0

In which: L(r)——noise level of Point R., dB(A)； L r0 )( ——noise level of Point R0, dB(A)；

ΔL——sound attenuation value, dB(A)。 The analysis of main noise source and operation noise of WWTP is listed in the table below.

Table 5-20 Noise source and attenuation value of WWTP attenuation di predicted noise level superposition insulation noise source location stance (m) day night dB（A） dB（A） dB（A） dB（A） dB（A） 40 m from north pump boundary of WWT 80～95 20 20 50 48 P 60 m from west b Sludge dewateri oundary of WWT 80～90 20 20 48 45 ng machine P 72 m from north 25 (blower blower boundary of WWT 85～110 40 54 49 hood) P medium vehicle 75～90 30 50 48 According to analysis above, all noise sources in WWTP operation period have different impacts on the environment. The blower has great impact on nearby environment. In order to reach the standard of urban area environment noise standard (GB3095－1996), attenuation distance of all water pumps, sludge pumps and vehicles would be 20 to 30 meter while attenuation distance of blower is 40m. Total areaof WWTP is 91200m2. The general layout plan of the WWTP indicate that the distance of pumping house to the north boundary of WWTP will be 40m, distance of dewatering machine house to west boundary of WWTP will be 60 m, distance of blower house to north boundary of WWTP will be 72 m. In another word, distances of those noisy equipments to the boundary of WWTP have already longer than the calculated attenuation distance. Therefore, the impact of equipment noise on enviornment is insignificant. The level of noise at boundary of WWTP, after attenuation will be in compliance with Class 2 (60 dB(A) at day time and 50 dB(A)night time) and 4a (70 dB(A) at day time and 55 dB(A) at night time of “Noise Emission Limits For Industrial Enterprises At Boundary”. The distance between all facilities and plant boundary is more than 50 which is longer than the attenuation distance caculated. So, the equipment noise do not have great impact on environment. 5.4.2.4 Environment impact analysis of solid waste Solid waste of this sub-project during operation is screenings, grid slag, and surplus sludge. The total quantity of grid slag and sand settled is about 400t/a. They could be sent to Ludian waste landfill site for disposal.

Page 121 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Moistures of surplus sludge would be reduced to 60% after dewatering and quicklime drying. The surplus sludge could be transported outside the plant after that. The quantity of sludge is about 2190t/a (including quicklime). They could be sent to Ludian waste landfill site for disposal. By adopting these measures, all the solid waste of this project would be treated or reused. It would not have big impact on environment. 5.4.2.5 Analysis of WWTP tail water reuse Reuse of tail water from WWTP serve for in-plant use, including watering the greenland and pathways, some productive structures washing (i.e floor of dewatering house, when structures are empty), , equipment washing (i.e. screens), Rreuse water should reach the relevant requirement of “Quality Standard for City Miscellaneous Water USE (GB/T 18920-2002).

Table 5-21 comparison of reuse water quality miscellaneous water quality standard(GB/T 18920-2 002) Pollutant discharge standard of vehicle washin urban WWTP parameter g, clearing GB18918-2002 city greening general cleanin Class I, B standard g Turbidity (degree) 10 5 10 — Soluble solid (mg/L) 1000 1000 1500 — SS (mg/L) - - - 20 Odor acceptable — PH 6.0～9.0 6.0～9.0 BOD (mg/L) 20 10 15 20 COD (mg/L) - - - 60 ammonia nitrogen(mg/L) 20 10 10 8 Total residual chlorine (m ≥1.0 after been contacted with chlorine, ≥0.2 (at — g/L) pipeline end) total coliform group(piece/ 4 3 4×10 L) According to the comparison above, there is gap between quality requirement of reuse water and wastewater discharge standard. The main differences are relected by such parameters as Turbidity, BOD, Total residual chlorine, and soluble solid, further advanced treatment will be necessary reuse of WWTP tail water. In FSR of this porject, a small grey water resuse system is to be established, including a storing tank of 20 m3 for resuable water, an integrated water purification plant with capacity 1~15 m3/h to purify reuse water. The integrated water purification plant, integrate purification reaction, sedimentation, filtering process as one. Its working principle is: tail water from WWTP is added with chemicals, fully mixed in the mixomg chamber, then flow into the reaction chambert at the bottom of the plant to form flocculent mass in fluid, flow into sedimentation chamber, where flocculent mass settled down and discharged as sludge, purified water overflow from the top and flow into an automatic filtering chamber to further reduce turbidity to lower than 5 degrees. The integrated water purification plant has advantages of higher effluent quality, quick sedimentation, lower power consumption, stable sludge discharge and convenient operation. Water quality from the integrated water purification plant will be in compliance with GB/T 18920-2002, and can be reusable. 5.4.2.6 Rational analysis of WWTP outlet location The setting of tail water outlet in WWTP could be analyzed by following aspects:

Page 122 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Firstly, the outlet of WWTP is located at the downstream of urban area, where there is now intake of water supply and no place where residents are densely populated. Secondly, the tail water will be discharged in Tuwei river and finally flows into Jinsha river. The water quality in Tuwei river is currently worse than Class V, the environment function of which is surface water body Class IV. Based on the discharge standard of pollutants for municipal wastewater treatment plant, the effluent water quality of WWTP should be the Class I-B. The tail water will not has big impact on the water body, but reduce the quantity of pollutants in the river body. Thirdly, based on code for design of outdoor sewerage engineering (GB50014-2006), the tail water in the project has installed disinfection facilities, which will apply the UV disinfection process for ensuring the public safety and avoiding the spread of infectious diseases. Chlorine disinfection is avoided to use, which will produce secondary pollution.

5.4.3 ENVIRONMENT IMPACT ASSESSMENT DURING OPERATION FOR RIVER REHABILITATION SUB-PROJECT

5.4.3.1 Environment impact analysis on air quality A special management institution would be set up during opertion. No other machines would be used if it is in a normal running. The managers use electric energy as the main energy in daily life. Because electric energy is a clean fuel, there would be no waste gas pollutant. There is no waste gas pollutant in the operation period. It would not have a big impact on nearby environemnt. 5.4.3.2 Environment impact analysis on water （1）impact analysis of water quality

——analysis of impact sources Analyze the impact on Liji River and Tuwei River after project completion. This report would adopt the method of “Objective-Responsiveness analysis” for this sub-project analysis. According to the FSR of this sub-proejct, the objective is: Interception of pollutant from entering into the river to improve water quality and ecological environment, protect water resource through comprehensive river rehabilitation of urban riverway, so that the urban water bady would be improved. Table below is an analysis of the sub-project objective and desinged project activities to respond the objective are made:

Page 123 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Table 5-22 designed subproject activities to respond objective No. Project objective Responsive project activity impact on river water quality 1 improve quality of river way water environment river way dredging direct impact 2 improve ecological environment of river way, River way landscaping direct impact protect water resource (greening) and dredging 3 avoid riverbank erosion and protect farm near riverbank protection direct impact riverbank project and flood control project Above table indicate that each specific sub-project objective are responsed by a designed proeject activity. The implementation of these design activites will accelerate imporvement of Tuwei and Liji rivers’ environment conditions definitely. ——Contribution of river silts dredging on the water quality imporvement of Liji River and Tuwei River. The river silts would be dredged and removed from river completely at the completion of the sub-project. That means the heavy metals in silt would not release into water body. The water quality of Liji River and Tuwei River would be improved. According to removal amout of sludge and heavy metal in sludge, the reduction amount of internal pollutant sources after river silt dredging is listed in table below.

Table 5-23 removal of internal pollution from riverway through river silts dredging Heavy metal copper Zinc Chrome Nickel Lead cadmium mercury arsenic reduction amoun 0.13-1.8 0.57-2.3 0.43-3.2 0.23-0.7 0.28-0.9 0.001-0.0 0.001-0.0 0.096-0.5 t 2 5 8 8 4 1 2 9

According to the table above, a big removal of heavy metal pollutant could be realized by silt dredging. It is good for the improvement of water qualtiy in Liji River and Tuwei River. In addition to the removal of heavy metals, organic pollutants and inorganic pollutants accumulated by river silt from urban area wil also be removed, hance to benefit to river water quality. ——domestic wastewater of river operation and maintenance operators The wastewater is mainly the domestic wastewater produced by the river operation and maintenance operators during operation. The wastewater quanatity is about 3 0.85m /d. And the main pollutants are CODcr, BOD5, SS, ammonia nitrogen, animal and vegetable oils. The wastewater could meet the requirement of Water Quality Standard for Discharging Wastewater into Municipal Sewerage CJ3802-1999, and further collected by municipal sewer network, treated by WWTP. The wastewater after treatment has little impact on the final receiving water body, Tuwei River. After the completion of the sub-project, the most sections of the rivers in urban area will be installed with intercepion trunk sewers and connected with WWTP, wastewater from riversides residents and units will be intercepted and delivered to WWTP for treatment without direct discharging into rivers. Only stormwater runoff are allowed to be flow into rivers. （2）Hydrology impact analysis

——river water flow There is no re-allocation of water quantity in Liji River and Tuwei River in the sub-project objectives as well as engineering measures to increase flows in Liji River and Tuwei River. So, the implementation of this sub-project would have no impact on the water quantities of Liji River and Tuwei River.

Page 124 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

——Water depth the relationship between water depth and water flow could be explained by using the following formula.

Q=u·BH

In which: Q is the flow, B is the river width, H is the water depth. The analysis shows the water volume at upstream will not change significantly after the completion of project. However the river for water flow is widened with the implementation of riverway dredging. Under the assumption of unchanged flow speed, the river will be deepened. ——hydraulic retention time With the completion of comprehensive river rehabilitation sub-project, part of the riverway would be broadened. The hydraulic retention time would become longer in the dry season. The water quality in some river section would worse. However, since the construction of associated Zhaoyang drainage network simultaneously, the project will improve the interception trunk alone the river sides to avoid the the urban wastewater discharging directly into Liji and Tuwei rivers. The combination of two projects would improve greatly the water qualities in Liji River and Tuwei River. Therefore, the worsening of water quality caused by river broadening would not happened. In general, the implementation of this project would has little impact on the hydrology environment. 5.4.3.3 Solid waste impact The main solid waste of this sub-project during operation will be the rover operators’ domestic solid waste. In addition, there’s a need to conduct a modest river waste cleaning, which will produce a certain amount of sludge. The quantity of sludge relies on the upstream ecological environment. All the sludge would be sent to Ludian County landfill for sanitary treatment. So, it would have slight impact on the environment. 5.4.3.4 Analysis of ecological environment impact （1）environment impact analysis of aquatic ecology

——impact analysis after silt dredging River rehabilitation sub-project will dredge the silt from river. According to the silt monitoring data, the pollutant concentration in the silt is relatively higher. It is an internal pollution source. At the beginning of sub-project operation, bottom material of the river would be cleaned because of the silt dredging. The recovery of aquatic ecosystem would be inhibited because of the same reason. However, the recovery ability of this ecosystem is not destroied. The whole sub-project would improve the water quality and the ecosystem would recover to natural status. Since the riverways in urbansections have been channalized with a few sub-mergent macrophate and algea and incomplete ecological function, the dredging in urban section and the increased water level will not impact on the normal growth of macrophytes. On the other hand, interceptor installation along the riverbank, that is incorporated in the wastewater sub-project will improve river water quality, which will benefit to the growth of sub-mergent macrophytes. It will play active role in restoration of river ecosystem.

Page 125 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

After the complemention of interception works along the river bank, organic pollution load to the river and biomass of phytoplankton in the river will be reduced. Based on the principle of repressive theory between vascular plant and phytoplankton, the decrease of phytoplankton will benefit to the significant increase of mactophytes in the river. After the river rehabilitation, the most of wastewater outfalls along rivers will be intercepted, pollution loads to the river will be significantly reduced, the quantities and population of microbs in the river which were nearly stablised before rehabilitation will be reduced. Resulting in the decrease of anaerobic microbs and increase of aerobic microbs. Decreased organic matter in water colume in river will benefit to the increase of desolved oxygen and increase of aquatic animals. ——Impact analysis after embankment slope protection The area related with this project is the river-reach of Liji River and Tuwei River in the urban area. This area has a high artificialization and is the centre of city. The riverway has been regulated several times. The riverway has been channelized and river configuration has been streamlined Concrete and masonry are used as the riverbank material. The construction of this project would not change the basic situation of this river-reach and higly artificialized river aquatic ecosystem. Furthermore, the proposed project activites do not involve any induration of riverbed, and will not impact significantly the existing mactophytes. Ecological embankment and slope protection methods, such as Gabion fexible structure, or the conbination between rigid and flexible structure will be applied to river sections outside urban area, in addition, the river bed will not be indurated, these structures will have no significant impact on the aquatic plants. The Gabion flexible struction for embankment slope protection contains many small openings in beteween filled gravels, so that river water and earth behind the structure can freely exchange, benefiting to the enhancement of self-purification capacity of the river and imporvement of river water quality. These small openings can also provide space for aquatic plant to grow, benefiting to the maintenance of ecological balance. After the completion of construction, water quality will be much more improved, but water depth in the dry seasons will be lowered. In general, the extent that river water quality improvement in Tuwei river and Liji river will be higher that the change extent of river hydrological conditions. Therefore, after the implementation, the river aquatic ecosystem will be partially rehabilitated to allow re-apperaence of fish and macrophyte. From the above, the implementation of this projec will improve the water transparency, promote the growth of plankton and submerged plant, and increase the species diversity and water oxygen capacity. All of these would be good for the quality of ecosystem. （2）impact assessment on terrestrial ecology After alternative analysis, the recommended types of embankment slope protection are: the combination of rigid-flexible ecological riverbank at sections where land acquisition is easier and possible, and combination of gabion pavement-gabion structureed slope. These types could fit the roads and landscapes well and utilize existing riverbank completely. The engineering quantity and investment amount is little. This type has a good stability and durability. The turf planted on the protection bank has a good water absorbing capacity, fixation, water and soil conservation ability as well as a good landscape. Green belt would be planted on the riverbank, including

Page 126 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

constant green broadleaf arbor, shrob and turf. In summary, this project would be good for the local ecology and landscape. （3）impact analysis on landscape According to FSR, the construction area of project greening is 68528.52 m2 and the area of cobble sidewalk is 133233.4 m2. The construction of green belt and cobble sidewalk would raise the greening percentage around Liji River and Tuwei River. The completion of riverway dredging would improve the water quality and the landscape around Liji River and Tuwei River. It makes the riverbanks of Liji River and Tuwei River becoming a place of leisure and recreation. 5.4.3.5 Impact analysis on social environment Although Liji River and Tuwei River went through several times of regulation, the water pollution is still a problem requiring for solution. The water pollution becomes a key issue for impacting the city environment, flood control and city development. Thus, only the scientific technical measures could raise the flood control cabability and avoid the destroy of ecoenvironment. The construction of this project could improve the landscape of Liji River and Tuwei River, enhance the environment quality of region along the river, and raise the flood control cabability. Zhaoyang is a city surrounded by hills and rivers. The treatment of riverway could improve city image and promote business development. This project has a good social benefit. Liji River and Tuwei River flow through the city. River rehability could prevent riverbank against erosion and protect farms near the river. This project could clean the water of Liji River and Tuwei River and raise the development value of farms near the river. The comprehensive regulation of Liji River and Tuwei River would raise the city’s flood control ability, reduce wastewater pollution and protect the city’s water body. The consummation of infrastructure would create a good investment environment, raise the value of city land, and promote development of local economy and society.

5.5 ENVIRONMENT RISK ANALYSIS

5.5.1 ENVIRONMENT RISK ANALYSIS OF WATER SUPPLY SUB-PROJECT

（1）Identification of important risk sourcs Liquid chlorine will be used for disinfection in Taiping WSP and Qingmen WSP. Taiping WSP will be equiped with 6 chlorine cylinders (1000 kg), and Qingmen will be equiped with 2 chlorine cylinders (500 kg). According to Technical Guidelines for Environmental Risk Assement (HJ/T 169-2004), critical weight of HCl generation is 20 tones at normal site, and 50 tones at storing site; while critical weight of Cl2 generation is 10 tones ar normal site and 25 tones at storing site. The designed storing weitht of liquid chlorine in Taiping and Qingmen WSPs are both lower than critical weight for at storing site. Therefore, chlorine dosage house in Taiping and Qingmen WSPs do not belong to risky sources. The presure pumping house for water distribution is designed to use chlorine dioxide for disinfection. Chlorine dioxide is to be made on-site by reaction between hydrogen chloride and sodium chlorate. Consumption of Chlorine dioxide for disinfection is at the rate of 3000 g/h, at the same time when

Page 127 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Chlorine dioxide are generated from reaction, about 1500 g/h of chlorine gas will be generated. Amount of hydrogen chloride to be stored and chlorine ags to be generated at presure pumping station will be much lower than critical weight. Furthermore, the site of presure pumping station dose not belong to sensitive area. Therefore, dosage house of presure pumping station does not belong to risky sources. (2) Analysis on accident sources The Taiping WSP and Qingmen will use liquid chlorine for the water disinfection. Pressure pumping stations add chlorine dioxide generated from for chlorine dioxide The risky accident will be the leakage of chlorine gas due to improper operation when cylinders are replaced, or due to breaks of pipes after being used for long time, or due to low quality joint washers of valves. In most cases, the imporper operation of the replacement of cylinders will cause the accident. The risk pumping stations include hydrochlorinc acid leakage accident, explosion of sodium chlorate, leakage of chlorine and chlorine dioxide. The chlorine and chlorine dioxide are produced by the generator of chlorine dioxide. The leakage of chlorine is always happened with the leakage of chlorine dioxide. The leakage of hydrochlorinc acid is caused by the valve leakage, wrong operation and equipment failure. The most serious leakage is from valve leakage. Even though the hydrochlorinc acid has an erosion effect on the environment, it has limited harm on the environment because the quantity of hydrochlorinc is little. The oxidation reaction between sodium chlorate and organics would release heat and cause fire. The sodium chlorate would produce lots of chlorine when it react with acid. Hydrochlorinc acid would explore under 40℃. The leakage of chlorine and chlorine dioxide is usually caused by wrong operation in dosage-adding, broken valve and equipment failure. Broken valve is the most serious situation for polluting the environment. The direct leakage of disinfectant produced by chlorine dioxide generator will have serious harm to environment. The chlorine is a toxic substance and the most harmful material in all the disinfection materials. （3）Environment risk analysis of accidents

①accident risk analysis of liquid chlorine cylinder implosion and chlorine leakage in Taiping and Qingmen WSPs Chlorine would not burn when leaking, but it would result in poisoning the people neary even to the death. ②accident risk analysis for fire and explosion of Qingmen WSP and pumping stations The fire accidernt is mainly from sodium chlorine accident The burning radius (D) and time of duration of fire accident (T) could be caculated by following the formula.

D(m)=2.66M0.327 T(S)=1.098M0.327

In which: the mass of burning material is M（kg） Because the actual dosage of chlorine dioxide in pumping station would be adjusted according to the residual chlorine in the water, the maximum dosage of effective chlorine is 4mg/l according to operation experience in other Chinese WSPs. 0.65g hydrochlorinc acid is needed for producing 1g effective chlorine. That means 98.84 kg and 197.68 kg of sodium chlorate would be needed for treating 38016 t/a and 55245

Page 128 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

t/a of clean water respectively for Qingmen and Taiping WSPs. The storage cycle is shorter than 10 days. Maximum storage of sodium chlorate are 0.9884 t and 1.9768 t respectively. At present, there is no uniform standard for identification of chemical material threshold for chemical dangerous source in China. EU published “Act of significant accident and risk in industrial activities” in June 1982. Standards for 180 material and its thresholds in this act. If one facility or one group of facilities which are cross-correlated in the plant gather hazardous material more than threshold, the facility or group of facilities would be thought as another major dangerous source. The limit of sodium chlorine in this act is 250t. Because the storage of sodium chlorine in this project is much less than the limit, it would not be a major dangerous source. According to the caculation, on the condition that the treatment capactiy of pump station is 38016 t in short term and 76032 t in long term, the burning radius of sodium chlorate ne is 25.41 m and 31.88 m respectively. The burning time are 10 s and 13 s. Explostion is a sudden energy release. The destructive shock wave and explosion fragments would result in projectile and damage. The temparature of fireground is high when breaking out of fire. The radiant heat is strong. Spread speed of fire is quick. If the fire is not put out promptly, it would result in large area damage. The environment damage of fire and explosion and the damage result of heat radiation, shock wave and projectile. Moreover, the fog and toxic gas in the fire would result in environment pollution in large area. According to caculation above, on the condition that presure pumpint station reaches to its design capacity in short term and long term, the maximum burning radius of the fire are 25.41 m and 31.88 m repective Therefore, when fire accident occurs, the fire are only limited within the storing house if no flammable articles are set fired. It would be urged that on flammable and explosive articles be stored in dosage storing house.

5.5.2 RISK ANALYSIS OF WASTEWATER SUB-PROJECT

（1）Abnormal discharge during operation Abnormal discharge of WWTP in operation period could lead to: 1) environment problem casued by untreated raw wastewater discharge, sludge bulking and discharge of odorous substance in abnormal operation; 2)large wastewater spillover casued by blocking and breaking of wastewater network. Abnormal operation casued by treatment machines and equipment failure would lead wastewater flowing into Tuwei River directly. The discharge parameters are in the table below.

Table 5-24 Pollution source discharge parameter of treatment unit under abnormal condition

Water q BOD5 CODcr SS TN ammonia nitrogen TP uantity mg/L kg/d mg/L kg/d mg/L kg/d mg/L kg/d mg/L kg/d mg/L kg/d m3/d 20000 150 3000 250 5000 160 3200 30 600 23 460 3.0 60 Assuming the WWTP is operated under abnormal conditions due to accident, all the collected wastewater will discharge into Tuwei river without treatment, which will mix completely with the river water at upstream. The COD concentration in the mixture will be calculated as following: C=（CpQp+Ch+Qh）/（Qp+Qh）

Page 129 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

In which: C——pollution concentration (vertical average, cross-section average) mg/L

Cp——emission concentration of pollutant, mg/L

Ch——concentration of the pollutant from river inflow, mg/L

Qp——wastewater discharge volume, m3/s

Qh——river inflow volume, m3/s The concentration of the pollutant from Tuwei river inflow is 57.9 mg/L; the Tuwei average flow in years is 21.7 m3/s (the monitoring average value on 3 continuous days in May 2009); COD concentration is 250 mg/L; and, the wastewater discharge volume is 0.231 m3/s (20,000 m3/d) From the formular above, the COD concentration under abnormal operational period of WWTP in discharged into Tuwei river will be 59.5 mg/L. the contribution of COD in the accident discharge is 2 mg/L. （2） analysis of abnormal discharging of wastewater due to sewer break During the opeartation of drainage pipe, it may be broken because of the rolling of vehicle and construction of municipal works. The wastewater would spill over and pollute the surface water after the break of network. If the network of water-supply breaks at the same time, the wastewater will pollute the drinking water and result in environmental accident. Anyway, this kind of accident is very low. For the environment risk caused by break of wastewater network, the management of wastewater network should be strengthened. First-aid repair should be carried out when wastewater network breaks, so that the leakage of wastewater and pollution of surface water could be reduced. This CEA requires the design and implementation units reinforce the anti-seepage and construction management in overlap region of wastewater network and water-supply network, so that the pollution accident could be prevented. （3）risk analysis of WWTP accident discharge The accident discharge of WWTP includes: 1) process failure and other accident. This kind of accident lead wastewater treatment could not reach discharge standard; 2) complete suspending of operation due to power cut or other reasons. This would result in the wastewater direct discharging into river; 3) wrong operation.

5.5.3 RISK ANALYSIS OF RIVER REHABILITATION SUB-PROJECT

5.5.3.1 Analysis of Environmental Risks during Construction

Main environmental risks during construction are identified to to potentially from dredged silts hauling, silts storing in the drying sites, final disposal of dredged silts. Risks analysis of them are specified as follows Impact of dredged silt hauling on environment After naturally drying at drying sites, the silts dredged from river, are to be hauled by vehicles to Ludian domestic solid waste sanitary landfill site for disposal. The volume of silt to be hauled is estimated to be 1675 m3 with moisture of 60%. Hauling distance is about 10.8 km, during which, polluting environment by silt leakage from vehicles would a risk.

Page 130 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Impact of silt drying sites on environment Exisint land use pattern of the pieces of land to be borrowed as silts drying sites are farmland use. Impermeable liners will be installed at the bottom of drying sites although there is no ground water to be used as drinking water sources at downstream of ground water flow direction, no ecological protection points or vulnerable points nearby. The impermeable liner will be made of a layer of 300 mm tamped clay, a filtration layer of 300 slag or gravels, installed with drainage trenches to convey leachate into rivers. According to the silt leaching test results of silts conducted by Yunnan Environmental Monitoring Centre Station on July 2009 for Liji River and Tuwei River system, contents of such pollutants of Ag, Ni, Be, Cr+6, Hg, F- CN-, As, Ba, Se, Cd, Cr, Pb, Zn, Cu and pH in silts can meet the requirement of Class A of “Integrated Wastewater Discharging Standard” (GB 8978-1996). At normally circumstances, there would be no significant impact of silt drying sites on environment. However, if the lining and drainage trenches for drying sites were disigned irrationally, there would ba a risk of fine inflow of dredged silts into rivers to increase SS in the river water. (3) Impact of final disposal of silts on environment According to the analysis of the features of river silts contamination, silts in different river sections will be disposed in different ways: dredged and dried silt from river sections outside urban areas be used for green land, while dredged and dried silt from river sections in the urban areas be hauled to Ludian solid waste sanitary landfill site for disposal. With regard to the first disposal way, heavey metals contents in silts to be dredged from river sections outside urban area compliance with “Control Standard for Agricultural Use of Sludge” (GM4284-84), and lower than Class III of “Soil Environmental Quality Standard” (GB 15618-1995), the requirement for woodland use. Therefore, the silts will not significanly pollute and harm vegetations. With regard to the second disposal way, it is the most safe way to haul silts to be dredged and dried to Ludian solid waste sanitary landfill site for disposal to ensure that the silt will not enter into open environment. Ludian solid waste sanitary landfill site is to be put into operation by June 2010 (refer annex 3 of this report).

5.5.3.2 Risk analysis on dam collapse

Environment risk of river rehabilitation is the destroy of outcome of river rehabilitation casued by the dam-collapes at upstream dam (Yanjiafen Dam, Qingmen Dam, Beizha Dam, Jiaojia Dam, Toudaogou Dam, Fangyangchong Reservoir and Shenggengtang Reservoir). The basic information of all dams are in linked projects section of this report. In the WB mission during the project preparation phase, independent inspection and evaluation of the 7 dams was conducted by WB dam specialist. Based on the exisiting issues, In the Dam safety Report, prepared by WB dam specialist, it i requires the reinforcement of dam safety management, development of operational maintanence manual and emergent plan for accident etc. all of the above could effectively reduce the risk of dam break and ensure the normal operation of the project.

6 ANALYSIS OF ALTERNATIVES

6.1 PRINCIPLES FOR ALTERNATIVES ANALYSIS AND CONTEXTS TO BE

ANALYZED

The comparison and selection analysis of the alternatives is conducted in 3 aspects: the 1st is analysis of the comparision between “with” and “without” the sub-projects; the 2nd is the comparison and selection analysis of construction sites; and 3rd is the comparison and selection analysis of technical programs. The general principles of the the comparison and selection analysis are: (1) Quantitative comparison and selection: For each alternative, to quantify the environmental impact of the project Implementation as far as possible. (2) Comprehensive comparison and selection: to analysize comprehensively in many aspects such as environment, techinic, economy, society and so on. (3) Compliance comparison and selection: the selected program is required to be compliance with the requirement of relative development planning and standards, and suitable for local conditions.

6.2 COMPARISON AND SELECTION BETWEEN “WITH” AND “WITHOUT”

SUB-PROJECTS

From the point of view of socio-economic and environmental gain and loss, the EIA analysed the project programs with or without 3 sub-projects. The results are shown in the table below.

Hence, from the socio-economic development and environmental protection point of view, the implementation of this project program surpasses the zero program, the project is necessary.

6.3 COMPARISON AND SELECTION OF CONSTRUCTION SITES PROGRAMS

6.3.1 COMPARISON AND SELECTION OF TAIPING WSP SITE ALTERNATIVES Considering the morphological characteristics and document supplied by the client, two sites have been defined through on-site investigation. The description and comparison of two sites are listed in table below.

Table 6-4 Alternative sites comparison and selection of Taiping WSP Alternative Site 1 (recommended Factors for comparison Alternative Site 2 site) Located at the cross of Zhao-Yi Located in city centre, south of Highway and Banghan Road, Taiping cluster, adjacent to old Location north to municipal motor downtown, elevation is between transportation company, 1938～1940m elevation is about 1933m.

6.3.2 SITE COMPARISON AND SELECTION OF QINGMEN WSP The proposed Qingmen WSP, located close to Zhaotong rail station, is at opposite side of Paoma road and Taiping Village. The elevation is between 2050~2052m. the raw water transmission pipeline of Dalongdong reservoir has already reach the site and the site meets the requirement of all the aspects for the construction of WSP. Thus, the FSR didn’t conduct the site comparison for the proposed Qingmen WSP. It’s admitted by the CEA that the proposed site for the planned Qingmen WSP meets the requirement of construction. There’s no sensitive point for noise and air environment, it’s far from residence area and it meets the requirement for environment Below is the comparison of the 3 alternatives (alternative 1: located close to rail station, oppposite site of Paoma road and Taiping village, the elevation is 2054.7m; alternative 2: located 200m south to the rail station, oppposite site of Paoma road and Taiping village, the elevation is 2054.7m; alternative 3: located in Donglongxun Village out of the planned area) for the construction of proposed Qingmen WSP from FSR for the water supply sub-project in north new area in Zhaotong urban area

Program 2 is recommended for Qingmen WSP

6.3.3 COMPARISON AND SELECTION OF WASTEWATER TREATMENT PLANT SITES

There are alternative 2 sites for the wastewater treatment plant comparison:（1）as per to the requirement of the municipal masterplan of Zhaotong, the wastewater generated from city centre and new city centre area will be discharged into the municipal wastewater plant, i.e. extension of existing WWTP on reserved land （2） considering build a new WWTP to the south of the new area which is at the intersection of Wayao River and Ganmei Road since existing WWTPs are far from the new area.

Alternative 1 has disadvantages in long distance wastewater transfer which goes through the old city center, difficult in construction; but it could make full use of existing WWTP facilities for future operation and management, which reduces the project investment. Alternative 2 has disadvantages in the location, which is in the city center, close to surrounding residential area, and is windward to the old city centre; the site is on farmland, which brings problem in land acqusition, then higher investment than Program 1. Hence the alternative 1 is recommended in the FSR, i.e. extension on the reserved land of existing WWTP.

6.4 COMPARISON AND SELECTION OF THE WATER TRANSMISSION ROUTE

There are 2 alternatives of the 2nd section of the water transmission pipelins（B-C）from north trunk aqueduct to Jiupu Town (refer to brief introduction of the project in detail). From the engineering and environmental perspective, the CEA analysizes in following: Comparison has been made from engineering perspective, see result in the table below: Route 1 is 2900m longer than Route 2, but without tunnels, easier for construction, 1.388M CNY less in investment than Route 2, so Route 1 is recommended. From environmental point of view, impacts in ecosystem, water environment and air environment is the same; but noise impact of Route 1 is larger than Route 2; Route 2 has tunnels thus its solid waste has a large influence on the environment. Whereas the main concern is on the tunnel in Route 2 goes through karst mountainous area, brings larger environmental risk than Route 1, plus more difficulties in maintainance. Hence Route 1 is recommended.

6.5 COMPARISON OF TECHNICAL PROCESS ALTERNATIVES

6.5.1 COMPARISION OF WASTEWATER TREATMENT PROCESS ALTERNATIVES In China, the mature and widely applied main treatment processes of urban secondary WWTP are A/A/O process, modified SBR process (ICEAS process), and oxidation ditch. The technical characteristicses of these processes are listed in the table below.

Based on the specific conditions of the project, biological treatment process mainly by oxidation ditch will be considered as recommended scheme for this project, the reasons include: （1）Existing WWTPs in Zhaotong City are using oxidation ditch process. The management of WWTPs in Zhaotong City get rich experiences in operational management and they could easily have the equipment supplied and staff allocated. （2）this process has a good adaptation ability and operational flexibility. It could meet the treament requirements in different period and make the effluent meet the design discharge standard. （3）Oxidation ditch process, which has a high organic loading and strong capactiy of

resisting impact load, was adopted. BOD5 could be reduced by 95％～98％ and

Page 138 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

CODcr could be reduced by 90～95％. This process also has a high ability of nitrogen and phosphorus removal. （4）A strong extendibility of oxidation ditch system In gerneral, in combination with the urban domestic wastewater treatment process in part of the cities in Yunnan, oxidation ditch process is recommended as the treatment process for Zhaotong new WWTP.

6.5.2 ALTERNATIVE SELECTION OF THE WASTEWATER DISINFECTION METHOD After the secondary treatment of municipal wastewater, the colon bacillus and virus still exist in the effluent. In order to ensure the public safety, prevent and control the infectious disease transmission, the Fecal coliform in the effluent is required to be ≤10000 pcs／L based on the Discharge standard of pollutants for municipal wastewater treatment plant. Thus, the tail water of WWTP is required to be discharged into natural water body after disinfection. The often used disinfection technique for the WWTP includes liquid chlorine disinfection, UV disinfection and ozone disinfection etc. the characristic of the 3 disinfection methods are summarized in the table below.

※the operational cost data is from Shanghai Minxing WWTP. Chlorine disinfectant has more shortcomings to overcome, which will especially produce lots of bad byproducts (e.g. Chloroform) for human and environment. Apart from it the difficulty in its large land occupying, the protencial risk of chlorine leakage

Page 139 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

should be fully considered. It’s reported that chlorine and oxygen will react with the organic matter in the water in recent years, which will has negative impact on the disinfecting effect. The halide out of the reaction is poisoning to human and animal that makes cancer, malformation and mutagenic substances. Ozone disinfection also has the problem of producing harmful byproducts and with long procedure for disinfection. The ozone generator is low efficient with high requirement of energy. Howevern UV disinfection will not produce harmful byproduct, which is reliable to the environment. UV disinfection also has an advantage of little contact time and easy civil construction. With the gradually concern of people over the impact of chlorinated organics in the domestic drained sewage on the receiving water body, the application of wastewater UV disinfection will become a mainstream. Through the analysis mentioned above, the disinfection method of the WWTPs in the projects will use UV disinfection.

6.6 ALTERNATIVE SELECTION FOR THE SOLID WASTE DISPOSAL

6.6.1 ALTERNATIVE ANALYSIS FOR THE DREDGED SILT DRYING 3 planned alternatives for the dredged silts drying will be compared. Alternative 1: Temporary air drying treatment Under this alternative, the silt will be treated in the following procedures: After the drying pits is levelled, the bottom will be laid with an impermeable layer (300mm thick soil), above which will be a filtering layer (300mm thick layer of big slag or gravel). The site will be divided into 12 cells (around 1000m2 each) separated by 1.1m tall brick wall. The silts will be dumped into the cell (from cell 1 to cell 12) with silt thickness of about 0.8m. At the middle of each temporary stockpiling cell for natural drying, a drainage trench filled with stone will be laid. The water will be drained through the trench network and discharged into river. Silt will be dried in drying pits and will not be hauled out to sanitary landfill site for disposal until moisture reduced to about 60%. It will take about half a month to stockpiling, weathering and hauled out and one stockpiling cell with 0.8 m high and 1000 m2 surface area will take about 1-2 days to dry the silt. Alternative 2: sanitary landfill site The procedure of the alternative is: Each drying site will construct 12 silts dumping cells from No.1 to No.12. Dumping pits in every cell is 1.15m deep. The soil dug will be put around the pit and formed a 1.15m bank. Each dumping cell could hold about 1000m3 silt. The drying cycle is 20 days, totally 20×3＝60 days; the silts will be transported to the dumping cell via vehicle or pipe. After natural sedimentation, the supernatant will be discharged into the rivers nearby. The residual surface water above the silts could be extracted and air dried. lime, gravel leachate drainage wells could also be set to hold the leachate in the drainage wells waiting for pumping out for silts consolidation. Transporting the consolidated silts in order from 12 dumping cells to landfill by vehicle. The 12 cells will be repeated for 3 times for cycling. alternative 3: mechanical dewatering method

Page 140 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

On the basis of alternative 1, mobile dewatering facilties would be put into use. It would use belt pressure-filtration method to fasten the dewatering speed of silts and cycle of sludge treatment. The advantage and disadvantage of all silts drying methods are listed in the table below

Table 6-10 alternatives comparison of sludge drying alternative advantage disadvantage 1 Low cost and no silt pit is needed. Natural Secondary pollution from silts. Smell air drying and temporary stacking would and odour will be produced while not affect the possible land use after the stacking. Times of transportation of completion of project. Easy management silts would impact the environment 2 Sanitary landfill. No secondary pollution. High investment cost, stacking, Time needed is short. excavating and transporting repeatedly. 3 Silts could be treated quickly. Low impact Comparatively high investment which on the environment is inconsistent with silts dredging alternative. because the silt dredging alternative of this sub-project is manual dredging, alternative 1 and alternaive 2 are consistent with the dredging alternative. Considering environment impact, construction difficulty, treatment cycle, alternative 1 is recommendated.

6.6.2 COMPARISON OF RIVER SILTS DISPOSAL ALTERNATIVES A leaching test was made by Yunnan Environmental Monitoring Centre Station for silts to be dredged from Liji River and Tuwei River. Result of leaching test is discussed in Section 4.2 of this report, which indicate that river silts do not belong hazardous waste. Furthermore, heavy metals in silts in river sections outside the urban areas meet the requirement of “Control Standard for Sludge Agricultural Use” (GB 4284-84). Different alternatives are considered for the disposal of river silts: Alternative 1. Mixing the silts with construction debris proporly for land levelling: for river silts with heavy metals compliance with GB 4284-84 and lower than Class III of GB 15618-1995, and with lower fertility, this alternative is applicable to level the ground of north new urban areas. This alternative can reduce the volume of silt to be landfilled, as well as the cost. River silts hauling distance is relatively shorter with lower cost of transportation. However, this alternative may potentially pollute ground water under the levelled ground. Alternative 2. Landfill: Although heavy metals in silts to be dredged from river section inside urban areas compliance with GB 4284-84 and lower than Class III of GB 15618-1995, they have been comtaminated by organic matters from urban sewage and garbage. In order to prevent the comtaminated silts from entering into open environment, the these dredged silts, after drying, should be hauled to Ludian sanitar landfill site for final disposal. The cost of this alternative is relatively higher. Alternative 3. Greenland use: for river silts with heavy metals compliance with GB 4284-84 and lower than Class III of GB 15618-1995, and with higher fertility, this alternative is applicable. They can be use directly on the greenland to be established under river rehabilitation sub-project. This alternative can effectively reduce landfill volume and cost. Nitrogen and phosphoruse in silts can also be fully used. Comparision of above three alternatives is shown in Table below

Table 6-11 Alternatives comparison on river silts disposal No Factor to be compared Alternative 1 Alternative 2 Alternative 3

EA propose following river silts disposal alternative

Table 6-12 Recommended alternatives of dried silt disposal Silts disposal Green land use landfill Sum Silt volume (before drying 87000 67000 154000 with moisture 90% Silt volume (after drying 21750 16750 38500 with moisture 60% A combination of both green land use and landfill is recommended by EA for the disposal of river silts, which can reduce the cosntruction cost and occupation of Ludian landfill volume. Heavy metals in silts to be dredged from rive sections outside urban area are lower than Class III of “Soil Environmental Quality Standard” GB 15618-1995, meeting the requirement for woodland use, it will not cause significant impact on vegetation. Reuse of waste is also a win-win solution.

6.6.3 COMPARISION OF WWTP SLUDGE DISPOSAL ALTERNATIVES The final sludge disposal includes: incineration, landfill and agricultual usage. The disadvantage and advantage is listed in the table below:

Table 6-13 Alternatives comparison on the WWTP sludge disposal Incineration Landfill Fertilizer Advantage: quickly disposed of, Advantage: after being landfilled, Advantage: sludge reclamation if dramatically volume reduction, sanitary sludge will be decomposed under the compliance with sludge application disposed of, low land occupation; reaction of microbes to reduce volume agricultural standard. Disadvantage: emitted gas pollution, higher and become stable; Disadvantage: Though there’s a tendency investment cost, complicated operation and Disadvantage: landfill method may be of sludge recycling for greening and maintenance, high operation cost, phased out with the reduction of fertilizing, heavy metal, Pathogens, consuming high energy. available land in the long run, helminth and organic toxicant that hard to Existing Zhaoyang economic strength is therefore, landfill is not the optimal decompose exist in the untreated sludge. not affordable. solution Without proper disposal and reaching the standard of sludge for agricultural use, the vegetation will be in danger.

Through the analysis above, the surplus sludge from WWTP, will be dewatered by mechine, further dried by mixing with quicklime to lower the moisture to 60%, and be finally hauled to Ludian waste landfill site for final disposal. While transporting the sludge, it’s strictly required to cover the sludge properly for transportation and to avoid the leakage and influence to the ambient environment. Meanwhile, IA should actively study the approach for sludge resource utilization. The sludge component should be indentified. If the sludge meets the standard of sludge for agricultural use written in table 6 of the Discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002), the sludge could be used as fertilizer for greening and forest nearby in order to reduce the cost for sludge disposal.

6.7 COMPARISON OF CONSTRUCTION METHOD ALTERNATIVES

6.7.1 COMPARISON OF WATER DISTRIBUTION AND SWERE PIPELINGE INSTALLATION ALTERNATIVES All pipeline installing methods have their own advantages and disadvantages. Comparison of three methods is listed in the table below.

Table 6-14 Comparison of pipelines installation alternatives technical method scope of application safety Environment impact investment requirement

Slope excavation is The traffic and project DN≤1500 small pipe. Low needed. Thus There progress would be affected if mature pipe groundwater level or no are construction the project is implemented on technique channel groundwater. It bears the low difficulty and risk if the main road. The construction and widely excavation conditions for slope geological condition is would result in surface applied excavation not good. subsidence, shock and noise

It should be constructed in soft soil No impact on the surface constructed layer and rich-water soft No excavation and it’s construction and the traffic. by pipe-jacking soil layer. The auxiliary high safe Small shock and noise professional measures for consolidating without disturbing surrounded team and soil could be avoided. This residents has certain could speed up the requirement construction progress. on the pipe material. High technical requirement. DN≤1000 pipe (the Non excavation construction. It should be construction level in No impact on the surface horizontal constructed province is ≤DN800). It’s construction and the traffic. directional Non excavation which by suitable for the normal soil Small shock and noise high drilling is safer professional layer and gravel and It without disturbing surrounded construction team and would be difficult for drilling residents and short has certain in rock construction period requirement on the pipe material.

The proposed diameter of water distribution pipelines are DN1300, sewer pipeline DN 400-1200. Most of the land along the pipeline are farmland. The soil coverage thickness for the pipe is about 1.0m. This depth is good for the excavation. The wastewater pipe and water distribution network are laid beneath municial main roads. It would be laid while the construction of road. Pipe channel excavation is recommended for the economical investment of project, except for pipe-jacking for a small section of sewer pipeline.

6.7.2 COMPARISON OF RIVER SILTS DREDGING ALTERNATIVES Main methods of river dredging are: dredging boat method, hydraulic dredging machine and pipe booster conveying methold and manual dredging method of river course excavation, pumping water by dam and manual desilting. (1) dredging boat alternative

Page 143 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

dredging boat for silt and waste dredging is high efficient and speedy at low cost. However it requires large scale of the river way for passing the dredging boat. However this alternative is not applicable to Zhaotong for there is no large water body and dredging boat. (2) hydraulic dredging machine and pipe booster conveying alternative The dam would constructed section by section in the riverway with an interval of 700~800m. the water in the dam would be drained or diverted. The hydraulic dredging machine would be installed after the riverbed is emerged. The high-pressure water jet would drop the silt pump under the design depth and forming a swag. A shallow slot would be swashed out in front of sludge pump. The soil around the shallow slop would be excavated in fan shape, and then the soil would be crushed and and transferred to silt site. After this work, the silt pump would be moved to carry out another work in the same method repeatedly. Characteristic: 1) It is easy for movement and loading with small size of the machine. The silt dredging is speedy with high concentration of dredged silt. The construction cost is lowered in this way. 2)the machine is flexible for operation, especially convenient for operation in narrow and complex river body 3) easy control of the construction quality. The whole procedure is directly visible . (3) manual dredging alternative the dam would be constructed section by section with an interval of 500~600m. the water in the dam would be drained or diverted. After the riverbed is emerged, the sludge dredging would be conducted by manually. This method requires high labour intensity with great impact on ambient environment. It could not be used in urban area. However, it could be applied in the suburb due to its simple process and low equipment investment. The 3 dredging alternatives mentioned above are suitable for river dredging in plain. However, when considering the small size of the river body in Zhaotong urban area, its low water level and the short bridge, only the hydraulic dredging machine and pipe booster conveying methold is recommended for dredging in old town region. manual dredging method is recommended for dredging in other river sections.

7 PUBLIC INVOLVEMENT AND INFORMATION DISCLOSURE

7.1 OBJECTIVE

After the information releasing and public participation, conduting questionnaire, seminar and analysis, the conclusion is made as following: （1）form the questionnaire of first public involvement phase, the respondents are certain awared of the EP. A majority think there will be a favorable eco and social benefit with the project construction, which will facilitate the development of economy in Zhaoyang district. They support the construction of project but they require to solve the portential environment pollution issues properly. （2）the public representatives at the seminar of the second public involvement phase supports the project implementation. They require necessary EP meassures to ensure no negative impact on the ambient environment. Most of the farmers’ concerns stay at the compensation for the land acquisition. The owner should communicate with the farmers as soon as possible to guarantee the interest of the farmers. （3）for the environmental issues reflected by public and for the requirement of the EP for the project construction, the project owner should ensure the EP work and take proper countermeasure for the pollution control to ensure all the pollutants meet the discharging standard and will produce no negative impact on the residents living by during the project construciton and operation phases. In general, through the analysis of the pollutant production and control and assessment of the environment impact of the project, the CEA agrees with the comments received from the public and social groups. The CEA also agrees the construction of project. The environmental issues raised form and concerned by the pubic is avoidable under strict production management and pollution control. The project owner should strength the communication with the public living by. The public benefit should be emphasised. The normal operation of pollution control facilities should be ensured by strict production management. The pollution control measures should be carried out while project construction in order to eliminate the doublts of the public and ensure the stable production, safe environment, stable society, development in harmony.

8 ENVIRONMENTAL MANAGEMENT PLAN (EMP)

8.1 OBJECTIVES OF EMP

The objective of this EMP is to propose environmental measures to mitigation potential nagative enviornmental impacts, to propose a enviornmental management insitutional system to implement this proposed mitigation measures. Responsibility of main parties involved will be defined. Training programs are also to be prepared to strengthen capacity to implement this EMP. Furthermore, environmental monitoring program are to be planned to indicate the outcome of the implementation of this EMP.

8.2 ENVIRONMENTAL MANAGEMENT SYSTEM

The Zhaotong Urban Environmental Project, as a component of the second phase of Yunnan Urban Environmental Project (YUEP), will be implemented strictly following the environmental management organizational framework established under YUEP.

8.2.1 RESPONSIBILITIES OF ENVIRONMENTAL MANAGEMENT INSTITUTIONS YNPMO will be responsible for the supervision of project planing, design and environmental protection, organization of training for environmental management staff in the province. Municipal PMO and EPB will be responsible for the execution of implementation program and technical standards, and daily supervision of environmental management. Municipal environemental monitoring station, delegated by the Owner, is in charge of the environmental monitoring of project area during construction and operation. The ennvironmental supervision engineer delegated by the Owner is in charge of the environmental monitoring. The Project Owner intends to assign specific environmental management staff to take charge of the environmental management in different phases; implement environmental laws, regulations and plans; review the implentation of environmental protection measures; promote advanced technologies and experience in environmental protection; organize trainings on environmental protection technologies for relevant sub-project staff for the capacity building. Because of the great differences in environment management between project construction and operation stages and that they could be short-term or long-term, the Contractor and Operator need to establish its specific management departments for these two stages. The management department for construction stage will be removed as this stage terminates and the department for operation period starts to function. The organization chart is shown in the figure below:

8.5.1 OBJECTIVES AND ORGANIZATION OF MONITORING Environment monitoring consists of two periods: project construction period and operation period. Its objective is to possess the dynamic information of the pollution of the proposed project, understand the impact of project construction on the environment quality, the scope of impact and the environmental quality during operation, report to the management department, and provide scientific findings to the project environmental management.

Page 201 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT

Environmental monitoring during construction and operation is conducted by local environmental monitoring stations delegated by Contractor or Operator. The monitoring stations should be Chinese certified organization, with good equipment and technologies and can carry out delegated monitoring task. According to anticipated effects of environmental impact, potential significant sensitive points should be chosen as monitoring points to trace pollution during construction and operation. Monitoring content includes noise, atmospheric and aquatic environment which have significant environment impact. Monitoring factors are determined by polluting factors of engineering pollution. Monitoring and analytical methods should follow those defined in Technical Criteria of Environmental Monitoring issued by MEP. Evaluation Criteria should follow national standard confirmed in the EIAs of each sub-project.

8.5.2 ENVIRONMENTAL MONITORING PLAN AND BUDGET DURING CONSTRUCTION AND OPERATION PHASES The estimated environmental monitoirng cost during construction and operation are shown in table below. Based on the proposed project implementation schedule, construction durations for water supply, wastewater and river sub-projects are 3 years, 2 years and 2 years respectively, with estimation monitoring costs of RMB 21,600 yuan, 18,880 yuan and 64,800 yuan respectivley. Monitoirng program for the three sub-projects are considered to be 3 years with estimated costs of RMB 194,400 yuan, 46,440 yuan and 30,600 yuan respectively. Total environmental monitoirng costs for both construction and operation period are RMB 376, 720 yuan. Project monitoring during the construction phase will be the responsibility of Zhaotong Environmental monitoring station(EMS) except noize which can be monitored by the construction supervison environmental engineer (CSEE). The monitoring during operation phase will be the responsibility of Zhaotong EPB or project owner. Most monitoring parameters during project operation phase belong to rountine work of Zhaotong EMS except water quality of Liji River and silt in both urban rivers. These newly added monitoring should be carried out also by Zhaotong EMS. In addition, soil conservation monitoirng program with estimated cost of RMB 241,000 were proposed.

9 CONCLUSION AND RECOMMENDATIONS OF ENVIRONMENTAL ASSESSMENT

9.1 CONCLUSION OF ENVIRONMENTAL ASSESSMENT

According to Decree No. 40 of the State Council of the People's Republic of China - Guidance Category for adjusting industrial structure (2008), municipal WS & WW network, WS source, WSP and WWTP project belong to the industries to be encouraged, in line with national industial policy. According to the Regulatory Planning of Zhaotong Municipality Urban Area (2007-2020), the project construction complies with the city’s overall planning. The project construction will complete the infrastructure of the urban environment, which provide the foundation for the ecological barrier of upstream of Yangtse river in Zhaotong city. The project will promote the image of Zhatong city, accelerate the social and economic sustainable development. After the completion of the project the water pollutants will be reduced to minimum and the eco environment around and in Zhaotong city will be protected. After the completion of project, the seperated system will be formed gradually in Zhaotong. The wastewater discharged in rivers will be directly reduced, which will improve the river water quality. It will significantly reduce the polution to the local water body because of the

Page 212 ZHAOTONG CENTRAL URBAN ENVIRONMENT PROJECT （YUEP PHASE II—ZHAOTONG COMPONENT） CONSOLIDATED ENVIRONMENTAL ASSESSMENT REPORT extention of WWTP. It’s planned to reduce the following pollutants discharged into Tuwei river: COD1387t/a, BOD949t/a, SS1022t/a, TN73t/a, NH3-N109.5t/a, TP14.6t/a. river rehabilitation will intercept the pollution of the urban wastewater on urban river, effectively remove the contaminants and pollution source accumulated in the river. The project will effectively improve the water quality in Tuwei and Liji river and the eco landscape of the urban rivers. Regarding the Water supply and drainage project, the location selection for WSP and waste water treatment plant were reasonable, and the drainage system, arrangement of sewer pipelines, service scope, service population and location selection of the proposed Qingmen WSP, Taiping WSP and existing WWTP are in compliance of and some even more optimized to the Controlling Specific Planning of Urban Masterplan Revision of Zhaotong Main City (2007-2020),. The wastewater sub-project is the construction project carried out under the notification of issuance for the integrated working plan of energy saving and emission reduction program and task division of energy saving emission reduction in Yunnan province by Yunnan Provincial Governement (Doc No. Yunzhengfa [2007]113) and urban wastewater treatment and recycling facilities construction planning of 11th 5-year plan. The project is also in line with the national industrial policies of the article 22 (high efficient and low energy consumption wastewater treatment & recycling technology development and facilities manufacture) of item 26 (integrated utilization of EP and resources conservation) of Category 1 (encouraged category) in the Guiding Catalog of Industrial Structure Adjustment issued by National Development and Reform Commission Order No.40. The pollution of river rehabilitation sub-projects comes from construction period. However the construction period is short. The impact could be under control providing the EP measures are carried out properly, EP funding is invested in time, and management is strengthened, thus, the discharged pollutants will not cause the change of local environmental function. The negative impact will be eliminated at the completion of project construction. After the project implementation, the water quality of Liji and Tuwei rivers will be improved obviously. The river sludge dredging will favor the recovery of the aquatic ecosystem. The project implementation can enhance the landscape of water body and greening, which provides a great urban living environment. The project will improve the flood control capability of Liji and Tuwei river in Zhaoyang district that will protect the life and property of residents living in Zhaoyang district. The value of land at both sides of the river will be increased. The project is with good social benefit. the main impact to be received from the operational period is positive. The wastewater, Exhausted gas, noise and solid waste produced during construction will meet their own prevention measures. The noise will not lead to exceedance of noise standard around the environmental sensitive point. The solid waste will receive proper disposal with little impact on environment. Construction will cause the disturbance on the regional eco environment. A certaiin water and soil erosion will be caused while construction of water transmission and distribution pipeline, river rehabilitation, WSP and WWTP. After applying proper measures, the water and soil erosion will be reduced. Though the environment will be impacted during the project construction and operation, the construction period is short and reversible. The impact could be reduced to minimum and stopped providing strengthening the construction management, developing proper construction schedule. With proper pollution control measures (including the countermeasure, measure and suggestion made in the CEA), the noise, odor impact on the residents will be miminzed to acceptable level during the operation. The grid slag, sadimentation and surplus sludge will send to Ludian waste landfill site for disposal, all of which will not produce new hazards.

Through public participation, information disclosure, questionaire survey, workshop and analysis to sub-project construction, the following conclusiong are made: the first public participation and phase I questionaire survey results indicated that the target groups had obtained certain level of enviornmental protection awareness. The majority of people recognized that the project construction owned relatively good socio-economic benefits, which would be favorable to promote economic development in Zhaoyang District, and would like to support relevant government authorities to settle the possible enviornmental pollution during construction. Representatives partcipating in the second time of public participation workshop consultation expressed support to project implementation, and required to adopt necessary enviornmental protection measures to insure that no adverse impact to surrounding environment. Villagers in genenral focused on land compensation, and PO should try to communicate with villagers as soon as possible and guarantee farmers benefit. Upon the enviornmental issues and relative requirements to project constructions from public, PO should make good arrangement of enviornmental protection, adopt effective pollution prevention measures, make sure all pollutants discharge meet standards, and leave no adverse impact to the living of local residents during project construction and operation phases. Through the risk anticipated, if there’s a chlorine leakage accident in Taiping WSP, the influence area is within 200m. The main victims of sodium chlorate explosion accident will be the staff working in the plant and the ambient air environemnt. With the implementation of risk prevention measures and emergency plan, the risk will be minimized. Duplicate power supply in WWTP is set to avoid the discharging of untreated wastewater into Tuwei river and downstream because of cutted power. In general, the positive benefits is standout after the project completion. The project construction is in line with coordinated development of the social, economic and EP and the principle of the EIA. Under the conditions of pollution control measure written in the Report, It’s required to strictly follow the bases of three simultaneous rules for safe, EP construction. The negetive environmental impact will be minimized after implementing proper EP measures. The positive benefit is far greater than the negative environmental benefit. the project is feasible in terms of environment.

9.2 RECOMMENTATIONS

4. operational record and monitoring report should be prepared and analysed prompty on a regular basis by the project owner. The project owner should establish sound technical fiiling system to accumulate technical experience for the operation and continuously improve operational standard and monitoring capability. 5. during the project operation, a strict safeguard system should be developed. It’s required to establish clear and mandatory operational supervision & management system in order to protect the basic environment water usage downstream. 6. It is recommended to relevant government agencies to close self-water supply at north new urban area, especially those who use ground water. 7. it’s suggested to strengthen the dam safety management of upstream and develop the emergency preparadness plan (EPP). It’s commented to conduct technical training to the dam management staff and to prevent the failure of the river rehabilidation due to the dam-break 8. Holistically scheduling the construction of water distruction network, interceptors along riverbanks, and river rehabilitation activities to avoid construction overlaps. Strict construction management, including construction programing, contractors mobillization, coordination, inspection should be practised through the entire construction process to minimize the impact of construction on peripheral environment. In summary, the implementation of ZTUEP would be environmentally feasible provided that all the measures proposed in the alternative analysis, mitigation measures, EMP, RAP, public consultations are well taken.
