Chapter I General
1.1 Foreword
The World Bank-financed Ma'anshan Cihu River Basin Improvement Project (hereinafter, the “Project”) is located in Ma’anshan Municipality, Anhui Province, between north latitude 31°40′03.82″-31°46′33.45″ and east longitude 118°29′36.13″-118°34′25.17″, as shown in Figure 1-1.
Figure 1-1
The embankment of Cihu River was constructed since the 1949 to prevent the flooding, however, now could only prevent the flooding with 10 years recourence. According the ‘Ma’anshan city flood control planning’ and ‘Ma’anshan city drainage project planning’, embankment reinforcement and slope protection will enhance the ability of flood control and urban drainage. This project is consistent with the relative plans of Ma’anshan, compriseing the following four components: management of Cihu river and improvement of rainwater drainage system, management of branch river systems, environmental management and monitoring, capacity construction and project management support. The Feasibility Study Report for the Project has been completed by Central and Southern China Municipal Engineering Design and Research Institute.
According to the Environmental Impact Assessment Law of the People’s Republic of China (PRC), Categorized Administrative List of Environmental Impact Assessment for Construction Projects, and other policies and regulations on environmental protection, the Project should prepare an environmental impact assessment (EIA). For this purpose, the Leading Group Office for Ma’anshan Cihu River Project under World Bank Loan contracted China Agricultural University to undertake the EIA task of the Project in November 2011. After accepting the appointment, we organized technicians to make a detailed investigation on the project area to collect engineering data. On this basis, we prepared the EIA Report for the Project in accordance with the Technical Guidelines for Environmental Impact Assessment.

2.2 Scope of construction and technical indicators
2.2.1 Rehabilitation of Cihu River and Improvement of Urban Drainage
1. Rehabilitation of Upper Cihu River
The scope of the rehabilitation of the upper Cihu River is East Ring Road—Provincial Highway 313, about 6.8 km long. Due to the influx of the Zhennan branch stream, the upper river course is divided into two segments, in which the East Ring Road—Hunan East Road segment is about 3.0 km long, connected to Xiushan Lake under construction on the north, and to the Yanghe River (main stream of the upper Cihu River) and the Zhennan branch stream (a branch river system in the upper Cihu River) on the south, and the Hunan East Road—Provincial Highway 313 segment is the Yanghe River (main stream of the upper Cihu River), about 3.8 km long.
The scope of upper Cihu River construction includes ecological revetment construction, landscaping and dike top road constuction.
(1) River course direction
The upper course area is a transition area between developed and undeveloped areas, where the upper river course will maintain its existing direction, and changeful riverbed and slope lines will be designed. Where it is possible to connect to riverside green spaces, wandering waterways and ponds may be built to create a diverse water environment.
(2) Cross section design
The upper Cihu River has a very low discharge at ordinary times, and no inland inundation has occurred. The existing cross section is largely sufficient for safe drainage. In the Project, a compound cross section will be employed, where the existing main channel will be maintained, and river flats will be built on both sides for wetland development or landscaping. The primary platform (waterborne platform) will be 1.0m wide, the outer slopes will have a gradient of 1:1.5, and the protective control blue line of the upper river course will be 10.0m out of the bank line. See Table 2-1 and Figure 2-1.

(3) Revetment design of the upper river course
Since the banks of the upper Cihu River are essentially natural earth banks with poor water and soil conditions, and vegetation and other bank protection measures are very deficient, landslide and soil erosion are very frequent. In the Project, the upper course revetments will be natural ecological revetments, and soil-reinforcing plants with a developed root system will be utilized to protect the river banks and ecology. In order to prevent the sliding of side slopes, the following measures will be taken:
1) To prevent the riverbed from heaving and the bases of the side slopes from
17
becoming unstable, woodpiles will be driven at the bases in a quincunx layout with 1.0m spacing.
2) 3-dimensional vegetation will be provided on the surfaces of the side slopes to reduce scouring by water flow and improve the landscaping effect.
(4) Maintenance road design
The upper Cihu River has no dike, and the maintenance roads will be arranged within 10.0m and not more than 4.0m wide. A concrete pavement will be employed, with a 22cm concrete surface layer, a 30cm cement-stabilized gravel layer, a 20cm lime, pulverized coal ash and gravel layer, and compacted plain soil.
(5) Landscaping design
The landform of the upper Cihu River is composed mainly of natural factors and green vegetation. Except trees and grasses on the banks and beside the river, hygrophytes and emerging plants may also be cultivated.
2. Rehabilitation of Lower Cihu River
The range of rehabilitation of the lower Cihu River is from Linli Road to the river entrance, about 6.3km long. Due to the influx of the Tianran River branch stream, the lower river course is divided into two segments, in which the river entrance—Tianran River segment is about 5.3km long, and the Tianran River—Linli Road segment about 1.0km long. The scope of construction includes dredging, dike body reinforcement, revetment and dike top road construction.
(1) River course direction
Most of the lower river course is in a built-up area, and the bank line is mostly straight. The dikes should be arranged to facilitate local urban construction planning and minimize environmental impacts. Therefore, the dikes will be arranged essentially along the existing river course direction without much adjustment.
(2) Cross section and revetment design
There are already dikes on both sides of the lower Cihu River, and the cross section is largely trapezoidal, but the river course is narrow and the flow section cannot meet the design flood discharge. In the Project, the lower river course will be broadened generally and the existing dikes will be set back. A trapezoidal section will be employed for most of the river course, with a gradient of 1:3 for the outer slope and 1:4 for the inner slope, and the slopes will be earth slopes mainly, covered with vegetation. In the Cihu Town segment, a rectangular dry-laid masonry section will be employed. The protective control blue line of the lower river course will be 10.0m out of the base of the inner slope. See Table 2-2 and Figure 2-2.

(3) Dike reinforcement design
1) Most of the dikes of the lower Cihu River are made of earth. In the Project, the dikes will be subject to dike reinforcement, anti-seepage treatment for dike body and shallow dike foundation, and dike foundation reinforcement, as detailed below:
① Dike body reinforcement design: by slope cutting outside and reinforcement inside;
② Anti-seepage treatment for dike body and shallow dike foundation: by concurrent cone penetration grouting for both the dike body and the shallow dike foundation;
③ Dike foundation reinforcement design: by pond filling;
2) Due to the low availability of land in the Cihu Town segment, reinforced concrete
19
floodwalls will be used to reinforce the dikes, and floodwalls with a length of 130m and 330m will be constructed on the left and right dikes respectively.
(4) Maintenance road design
The access road of the lower Cihu River will be on the dike top, with a planned width of 8.0m, 1.0m wide road shoulders and 6.0m wide motorized vehicle lanes. A concrete pavement will be employed, with a 22cm concrete surface layer, a 30cm cement-stabilized gravel layer, a 20cm lime, pulverized coal ash and gravel layer, and compacted plain soil.
(5) Landscaping design
The lower Cihu River area is a densely populated urban area, where it is more suitable to grow trees and grasses on the banks and beside the river, such as willows.
(6) River course dredging
The average sediments thickness of the existing river course is about 0.5m, and the amount of sediments to be dredged will be about 77,000 m3. Dredging will be conducted by hydraulic dredging in sections, delivery of sediments to a stockpile site for temporary storage and sedimentation, and transport to the Xiangshan landfill where the sediments will be further dried and used as cover soil.
3. Reconstruction of stormwater pumping stations
According to the Urban Master Plan of Ma’anshan Municipality, the catchment area of the Cihu River basin in the urban planning area is 85.29 km2, including 43.62km2 in the upper hilly area (gravity drainage area) and 41.67km2 in the embankment area (pump drainage area). The pump drainage area west of the Cihu River is 16.79km2, all in the built-up area or planned built-up area; the pump drainage area east of the Cihu River is 24.88km2, in which 15.52km2 is in the built-up area or planned built-up area, and 8.51km2 is in the suburb. 14 storm water drainage zones have been planned in the Cihu River basin as follows:
Storm water drainage zones in the lower course—Magang new area, Nantang, Sulfuric acid plant, Zhaoming, Xiaonanwei and Zhendong zones, located mainly in Cihu Industrial Zone.
Storm water drainage zones in the middle course—Xiaohezha, Yangqiao, Xitang, Xiaohecha, Linli, Fengshou and Fengqiao zones; the west zones are mostly in the built-up area and the east zones in the newly developed district.
Storm water drainage zones in the upper course—Xiangshan zone, including the market town and the newly developed district.
It is planned to expand the existing stormwater pumping stations for the 14 storm water drainage zones. The existing stations have a total installed capacity of 52.15m 3/s, which will be expanded to 150.9m3/s. See Table 2-3.

2.2.2 Rehabilitation of Tributaries
This Component comprises rehabilitation of 19 branch rivers, with a total length of 32.05 km, and 2 ponds as rainwater retention ponds, including ecological revetment construction and landscaping. This Component also comprise rehabilitation of left side of Lijianwan river, including dike reinforcement, slope protection, landscaping and dike top maintenance road construction, and the 19 branch river systems, including dredging, slope protection, landscaping, and dike top maintenance road construction.
1. Rehabilitaiton of Lijianwan river
21
Lijianwan river is the branch of Cihu river. The Lijianwan river discharge into the downstream of Cihu sluice, connecting the Yangtze river. This river is the boundary of Anhui and Jiangsu provinces. The right side belongs to Jiangsu, and the right dike has been constructed to the standard. The left side belongs to Anhui, where the dike is still the earth embankment. This project will rehabilitate the Lijianwan river of 1.7km length, including dike reinforcement, revetment, maintenance road construction on the dike top, and greening.
(1) Dike reinforcement design
The detailed of standard sections of the dike could be seen in table 2-3.

Dike level Over height of dike top /m
Width of the dike top/ m
Slope facing water
Back water slope
4 1.0 8.0 1:2 1:2.5
1) Dike body reinforcement and heightening
Outside slope of the dike will be cut. The dike body will be reinforced to reach the section standards.
2) Filling ponds and ditches
The ponds and ditches closed to the dike will make the dike risky. Some ponds are as deep as 2.5m; highly weakening the solidity of dike. So, the ponds and ditches within the distance to the foot of the dike of 20m will be filled up, beyond the ground level for 0.5m (allowable settlement).
3) Anti-seepage of the dike body
The soil uniformity is poor of the left side dike of the Lijianwan river. Clay soil grouting will be used to anti-seepage of the dike body.
(2) Sloping design
According to the “Levee engineering design specifications”, the sod revetment on the embankment which faces the water could resist level 4 or less waves and water scouring slower than 2m/s. both slopes of the embankment will apply the sod revetment.
(3) Maintenance road on embankment
The road surface on the left embankment of Lijianwan river is bare soil.
The access road of the lower Cihu River will be on the dike top, with a planned width of 8.0m, 6.0m wide motorized vehicle lanes. A concrete pavement will be employed, with a 22cm concrete surface layer, a 30cm cement-stabilized gravel layer, a 20cm lime, pulverized coal ash and gravel layer, and compacted plain soil.
(4) Landscape greening
This project planning to greening the embankment top and road shoulder, as well ass the embankment in 25m scope.
2. Rehabilitation of the branch river systems
In the Project, besides the Lijianwan river, 19 branch river systems and 2 ponds including Hupo pond and Yaochang pond will berehabilitaed for a total length of 30.35km, located in the Jiandanzha, Xiaonanxu, Zhendong, Nantang, Xiaohezha, Yangqiao, Xitang, Xiaohecha,
22
Linli, Fengshou and Fengqiao zones respectively. The scope of construction includes dredging, ecological revetment and landscaping. See Table 2-6.

(1) Plane direction
Most branch river systems in the middle Cihu River are located in the built-up area or planned built-up area. Due to the restriction of land planning, the branch river systems will maintain their existing directions, and bended or straightened locally.
(2) Cross section and revetment design
24
A trapezoidal section will be usually employed for the branch river systems in the middle Cihu River. The bank slopes will be mostly made of earth, and covered with 3-dimensional vegetation. Where land use is restricted seriously, a rectangular dry-laid masonry section will be employed. See Figure 2-3.
Trapezoidal section Rectangular section
Figure 2-3 Cross section design of the branch river systems in the middle Cihu River
(3) Road and landscaping design of branch river systems
2m wide sidewalks will be provided within the controlling range of the branch river systems, and vegetation will be cultivated in the remaining spaces. The sidewalks will be made of 6cm thick pre-fabricated slabs, with 2cm cement mortar (1:3), 15cm graded gravel and compacted plain soil.
(4) Dredging of the branch river systems
The total amount of dredging of the branch river systems will be 79,700 m 3 based on the design thickness of 0.3m. In low flow season, the water in the river will be diverted by cofferdams which will be constructed in stages. The water within the cofferdam will be pumped out into the river couser downstream of the cofferdam so as to ensure the air dry of the sediments exposed. Mechanical method will be used to dredge the sediments when they are dried. Tankers will be used to transported to Xiangshan Landfill. As the pumps to be used are in small size, the noise from the pumps is minor, and will not affect the surroundings.
2.2.3 Environmental management and monitoring
1. Cihu river basin management systems
The systems would enhance the supervision of the whole basin by local relevant departments. The governments in each district should establish long term management of the basin environment, with long term documents managing systems, annually examining systems, and daily supervision systems. The governments in each district should also establish operation systems, to conduct joint law enforcement, intensify law enforcement, enhance the investigation and treatment of illegal drainage sewage, illegal construction, illegal land use and acquisition, channel jam and damage. The systems would promote effectively control and prevention of basin environmental pollution and ecological violation.
25
2. Aquatic environment monitoring system of the Cihu River
An automatic water quality monitoring station will be constructed for monitoring by the Ma’anshan Central Environment Monitoring Station on a monthly basis. There are 25 monitoring indicators, including water temperature, pH, conductivity, dissolved oxygen, COD, total nitrogen, total phosphorus, etc. During the implementation of the World Bank-financed project, extra monitoring will be performed as necessary. Currently, the Ma’anshan Central Environment Monitoring Station can essentially meet the monitoring requirements.
3. Environmental early warning system for the Cihu River basin
In order to integrate water quality monitoring data and strengthen environmental risk prevention capacity, a water quality evaluation model for the Cihu River will be established, where GIS technology will be applied to develop an integrated monitoring data analysis software and a release platform of early warning signs, realize the visualization of forecast, early warning and simulated analysis, and improve the overall analysis and evaluation level of aquatic environment quality. The establishment of the environmental early warning system for the Cihu River basin includes hardware purchase, network operation and maintenance, GIS platform development, development of water quality evaluation model, integrated monitoring data analysis software and early warning platform software, and staff training, which will be implemented by the Information Center of the Ma’anshan Municipal Environmental Protection Bureau.
4. Establishing a mine management system
The mine protection plan will be developed, covering the background, present situation and existing problems of mines in the Xiangshan area, mitigation measures and follow-up monitoring. Environmental problems arising from mining will be prioritized, and pertinent mitigation measures proposed and their feasibility analyzed. The focus is to eliminate the potential risk of river water quality degradation by acid water.
2.2.4 Capacity building and implementation support
1. Expert, consultant service
It is necessary to hire experts and consultants to assist the review of the design document and bidding documents, manage the project and construction, supervise social/environmental security plan, and establish the monitoring system and the completion report.
2. Ability construction
The staff of the project office and construction units will promote their ability, through training, visiting, to ensure the successful project implementation.
3. Office facilities
Necessary facilities will equipped to cooperate the project implementation of the project office.

Chapter Ⅲ Project Analysis
3.1 The Conformity of Industrial Policies
According to Catalog of Industrial Restructuring Guidance (Version 2011) (No.9 2011, NDRC), this engineering project falls into the first type of encouraged projects: “Second, Water Conservancy, 1. River dam construction and watercourse and reservoir treatment project”, thus it conforms to the industrial policy of China.
3.2 Analysis for Conformity of Plans
1. Urban Flood Control Plan of Ma’anshan Municipality
31
According to Urban Flood Control Plan of Ma’anshan Municipality, the dam of Cihu River shall be designed to be safe when it confronts with once-in-two-decade flood, and shall be tested according to the standard that it can withstand once-in-five-decade flood.
The upstream of Cihu is a natural watercourse with a relatively smaller water flow, which has dam only along the reach near Donghuan Road. No dam is built along the other reaches since generally no flood happens there. Therefore no change is planned to be made there. In the upside of the downstream, the bottom width of the watercourse basically satisfies the requirements of the design. However, the main side slope and crown height of the dam is insufficient, so it is planned to do scaling on the side slope and retreat building in some reaches, considering the environmental construction design. Meanwhile, neither the bottom width nor side slope in the downside meets the requirements. Therefore scaling is planned to be done on the left bank and retreat building is designed to be adopted on the right one.
In the construction of Cihu River Dam, more attention should be paid to seepage proofing, the handling of potential safety problems in dam body and the reinforcement and danger-rooting of architectures across or through the dam. As for reaches where dam section is thin and current scouring happens, the construction of dam and embankment should be combined together with proper protection. To strengthen the overall flood control capacity of Cihu River, greater efforts should be made and more funding should be invested in the river.
2. Urban Drainage Engineering Plan of Ma’anshan Municipality
According to the Urban Drainage Engineering Plan of Ma’anshan Municipality, water in the depressions along Cihu River should be drained naturally or through pumping. Due to the higher terrain of the upstream, rainwater can flow out of Cihu River and arrive at both sides of its downstream, where pumping stations are needed to pump rainwater in urban and suburban area into Cihu River during the flood season of Yangtze River.
The west-side pumping area of Cihu River covers a range of 16.79km2, where 11 pumping stations have been completed and others are in design. But the overall pumping capacity is relatively not enough owing to the small scale and poor equipments of most stations. So it is planned, according to the water catchment, to reduce the station number to 8, and enhance their capacity to standard. While in the east-side pumping area, which covers 24.03 km 2, water catchment, 15.52 km2 completed or in design and 8.51 km2 in suburb, it is planned, according to water catchment, to make alteration or expansion to existing pumping stations, and check and ratify the stations to be built in accordance with both urban and rural flood control standard. The details are as follows:
(1) Magang New District Zone
Magang New District Zone covers a catchment area of 3.15km2, where Santie Pumping Station, Ergang Pumping Station and Tongyi Pumping Station are in use to pump flood water into Cihu River at a rate of 2.4m3/s. According to the drainage design of Magang New
32
District, 2#, 3# and 4#, these three pumping stations will be built with a rate respectively at 20.2m3/s, 9.5m3/s, and 19.7 m3/s.
Besides, the existing three ones will be done away after the completion of the above pumping stations.
(2) Nantang Zone
In Nantang Zone, which covers a catchment area of 2.01km2, water logging is quite severe as a result of the silting up and encroachment in the 2.6km-long Nantang river system and the inadequate capacity of Tongyi pumping station (only 2.4m3/s) at the outlet. A thorough improvement of Nantang river shall be done in accordance with the requirements of the design to satisfy its discharge capacity. At the same time, it is planned to expand No.2 Tongyi pumping station and raise its capacity to 6.30m3/s, and abolish Zhennan Pumping Station (0.4m3/s) after the connection of drainage ditches.
(3) Xiaohezha Zone
It covers a catchment area of 2.24km2 and is encircled by Nanjing-Wuhu Railway, Geyang Road and Cihu River. The serious blocking and poor drainage in the upstream of Xiaohezha River leads to water logging in Jiankang New Village on the south side. According to the project, the whole Xiaohezha river, 2.3km in length, will be improved by expanding the capacity of its pumping station from 2.4m3/s to 6.8m3/s. Meanwhile, Tuanjie Pumping Station (1.2 m3/s), closely next to its north side, will be abolished according to the plan, because of its outdated equipments and disrepair, and the fact that it is connected with the catchment area of Xiaohezha.
(4) Yangqiao Zone
Covering a catchment area of 4.71km2, this area is separated by Jiangdong Road into two parts, the urban built-up area in the west and the short-term planning area in the east. In this zone, natural river courses such as Jiumugou river, Wangbaitan river , Wangmutang river, etc. connect with each other. In the light of the project, these natural rivers will be kept to afforestation and improved to guarantee an unblocked draining and the function as a regulating reservoir. Particularly, the pumping capacity of existing Yangqiao Pumping Station will be expanded from 8.2m3/s to 15.5 m3/s. At the same time, the simply equipped No.2 Yangqiao rural pumping station (1.2 m3/s) next to the south will be discarded after the connection.
(5) Xitang Zone
This zone covers a catchment area of 2.32km2, where rainwater flows through pipes, into Xitang River and then pumped into Cihu River. A length of 1.8km of the river will be kept and improved in line with the project. And the pumping capacity of Xitang Pumping Station will be raised from 2.2 m3/s to 6.7 m3/s.
33
(6) Xiaohecha Zone
This zone covers a catchment area of 2.36km2, where rainwater flows through Xiaohecha river, collects and then is pumped into Cihu River. This river is planned to maintain a length of 1.7km2, and will be improved instead of being filled up. And the pumping capacity of Xiaohecha Pumping Station will be raised from 3.6 m3/s to 8.5 m3/s.
(7) Sulfuric Acid Plant Zone
This zone, with a catchment area covering 1.20 km2, currently belongs to Cihu Industrial zone. Along the east side dam of Cihu River, there lie Jiandanzha Pumping Station and Sulfuric Acid Plant Pumping Station, with a respective rate of flow at 2.2 m 3/s and 3.15m3/s. This project plans to keep and expand Sulfuric Acid Plant Pumping Station to 5.7m 3/s and abolish Jiandanzha Pumping Station. At the same time, it will dredge and improve all the natural channels.
(8) Zhaoming Zone
In this zone, which covers a catchment area of 2.83 km2 and currently belongs to Cihu Industrial zone, rainwater is pumped by Zhaoming and Carbon Black Plant pumping stations into Cihu River after collecting through Lianhe river. So it is decided to preserve and improve current Lianhe river and expand the pumping capacity of Zhanming to 6.9m3/s, while the Carbon Black Plant (1.6m3/s) will be kept in recent years and then abolished in the future.
(9) Xiaonanwei Zone
In this zone, which covers a 1.37 km2 catchment area, rainwater is pumped into Cihu River by Xiaonanwei Pumping Station with a capacity of 1.2 m3/s, which will be enhanced to 4.2m3/s. And in the light of the project, the Zhenbei Pumping Station with a flow rate at 0.40 m3/s, will be abolished. Besides, all the natural water system will be preserved and improved.
(10) Zhendong Zone
With a 2.0km2 catchment area, this zone belongs to Jinjiazhuang Industrial zone. And the rainwater there is pumped into Cihu River by Tailai, an agricultural pump with a flow rate at 1.4m3/s. It is planned to keep and improve the Zhendong river along with the development of the industrial zone. Then Tailai Pumping Station there is designed to be re-constructed into one with a 5.2m3/s rate of flow and a capacity of 6000m3 as a regulating reservoir.
(11) Linli Zone
This zone covers a catchment area of 3.58km2, the north-of-Linli-Road part of which belongs to Jinjiazhuang Industrial zone. In the project, Linli Pumping Station is to be re-constructed with a 10.8m3/s pumping capacity, which will pump rainwater in that area into Cihu River. In the short run, the agricultural pumping stations, Paishantou (0.8m3/s) and Linli (1.2m3/s), will be kept, but they will be abolished when river improvement and pumping station construction
34
are completed.
(12) Fengshou Zone
With a catchment area covering 11.2 km2, this zone is currently utilized for agricultural purpose, but the southwestern part of which, with Donghuan Road. and Lüyou St. as the border, covering 3.49 km2, will be turned into urban area and the northeastern part, covering 7.71km2, into suburban area within the designed time limits. The drainage capacity of pumps there is quite low, with Gaohan Pumping Station’s capacity at 3.6m3/s and that of Shanghu at 1.2m3/s.Based on the facts, the project is aimed to build a new Fengshou Pumping Station with a capacity of 20m3/s at the location where the security gate at the outlet of Fengshou River System lies, which satisfies both the standard for urban draining and that for rural draining, in order to properly preserve existing natural rivers.
(13) Fengqiao Zone
his area, which is now used as agricultural land includes a catchment area of 1.85km 2. There are Fengqiao (0.4m3/s) and Dingjiaba (1.2m3/s), these two pumps along the embankment of Cihu River. This project plans to make an extension to Fengqiao pump and enhance its pumping capacity to 4.9m3/s, while Jingjiaba will be kept for a short time but eventually will be abolished in the future. Besides, it attempts to protect the existing natural rivers with moderate canalization, so as to satisfy the requirements of draining as well as landscape.
(14) Xiangshan Zone
Rainwater in this zone, which contains a catchment area of 43.62km2, flows through various branches of Cihu River in the upstream, converge and then into the River, with no need for pumps. Therefore, it is planned to maintain the natural draining system there.
3. Plan on Comprehensive Water Environmental Improvement in Cihu River Basin, Ma’anshan Municipality
(1) Tasks and objectives
This project aims to build the dam into one that can prevent once-in-two-decade flood by adopting measures such as reinforcement and seepage-proofing of dam body, reconstruction of the revetment, dredging of sediments and others. It applies the same standard to its drainage, which will be met with efforts in the combination and optimization of draining zones and pump stations, and the reconstruction of structures running through or across the dam, such as sluice gates, bridges, and so on. Furthermore, it endeavors to realize its objectives to gradually improve the water quality of Cihu River and meet the requirements of functional zoning with measures like wetland treatment, dredging, and water supplement. And finally, it tries to create a harmony between the ecology and landscape of Cihu River with help of the design of lake view and urban greenbelt view and so on.
(2) Specific contents of the project
35
This project considers mainly aspects such as flood control, drainage, water quality improvement, ecology and landscape and others, which includes the specific contents below:
1) Flood control and drainage project: dam alteration, river way widening, dredging, construction of flood retarding lake, re-building of water-blocking bridges, construction of pumping stations , draining pipes, etc.
2) Water quality improvement: the laying of pollution interception pipes along the river, sewage treatment plant extension, tail water utilization and ecological water supplement in the watercourse and so on.
3) Landscape engineering: the creation of views along the mainstream and branches and water culture development.
4) Water ecological restoration project: the reconstruction of ecological revetment and river bed of its mainstream and branches, and the development of model ecological reaches.
In conclusion, the tasks, objectives and contents of this project are consistent with Urban Flood Control Plan of Ma’anshan Municipality, Urban Drainage Engineering Plan of Ma’anshan Municipality , and Plan on Comprehensive Water Environmental Improvement in Cihu River Basin, Ma’anshan Municipality . So it can be said that this project conforms with the requirements of various plans of Ma’anshan Municipality.
3.3 The Analysis on Pollution Sources in the Project
3.3.1 Analysis of the pollution source within construction time
The term of this construction work, which will be divided into sections and done by stages, runs from 2013 to March, 2017. During the construction, it is inevitable to occupy the land and tread on plants, causing damage to local ecological environment. Besides, noise, waste water, fugitive dust, odour, mud and other side effects resulted from construction will exert ill influence on the surrounding environment.
1. Wastewater
the sand and gravels used in the project will be purchased thus avoiding the need to wash these materials.Only some simple mechanical maintenance will be done on the construction site but without washing. Therefore, the waste water, generated within construction time, were mainly the supernantent from the dredged sediment stockpiling siteand domestic sewage of the construction workers.
(1) Supernatent from sediment stockpiling sites
The project adopts the technology of cofferdam drdging in its branches, and hydraulic dredging in the lower reach of Cihu river. The sediments will be transported to the sediment stockpile yard through pipes. So the wastewater from the dredging engineering was mainly the supernatant. The main pollution factors of the supernatant is SS, which affects little to the surface water after settling tank, and could discharge into Cihu river directly.
(2) Domestic sewage of the construction workers
36
The domestic sewage of the construction workers containing water pollution factors such as COD, NH3-N and SS. See Table 3-1 for the number of workers and construction period for each construction section.
Table 3-1 Number of workers and construction period for each construction section
Construction section Construction time:
The number of constructors

Lakes and branches of Cihu River in Hi-tech Zone 2014-2015 100 18 months
Branch rivers and pumping stations in urban area 2013-2017 100 51 months
Branch rivers in urban area 2013-2017 100 51 months
It is supposed that each worker consumes 60L of water a day and 80% of the water become sewage, the concentration of pollutants in which goes as about 350mg/L of COD, 25mg/L of ammonia nitrogen and 150mg/L of SS. Details about domestic sewage from the construction is shown in Table3-2. Since places along the river are mostly residential area, existing living facilities nearby the construction sites can be made use of. In addition, it is estimated that during the peak time of the construction period, totally about 200 workers will be working in the whole project.

2. Waste gas
The impact upon air environment mainly comes from air pollutants within the construction period, mainly fugitive dust, malodorous gas , and waste gas emission.
(1) Fugitive dust
Fugitive dust is mainly generated in the processes such as the transportation and stacking of materials, river dredging, dam reinforcement etc., where with the help of wind, the construction site and their surrounding will be polluted. In addition, passing transport vehicles will cause second pollution of fugitive dust on the road. Measures, such as regular road-surface watering, stacked materials covering and transport vehicles blanketing, are designed in this project to control fugitive dust within construction period.
(2) Malodorous gas
Malodorous gas , mainly NH3-N and H2S, will emerge during dredging and the stacking of sediments, and its intensity generally ranks level two or three, according to analog data.
(3) Influence of waste gas emission
Waste gas, which is mainly caused by the fuel burning of construction machinery and transport vehicles, includes smoke, sulphur dioxide, nitrogen oxides, carbon monoxide, and other pollutants.
3. Noises
Noises, generated by construction machinery such as excavators, auto-dumpers, bulldozers,
sludge pumps, generally range from 90 to 95 dB （ A ） and will have certain negative
influence on sound-sensitive places along the river.
Therefore, low-noise equipments are planned to be used in this project, and other measures will also be carried out in order to mitigate noise impact, such as reasonable time management, proper equipment arrangement, and fencing etc.
4. Solid waste
Solid waste produced in this construction includes dredged sediments, solid waste and domestic garbage of workers.
(1) Dredged sediment
This project will carry out dredging with hydraulic method in the lower reach of Cihu River, which amounts to 77,000m3. This project will also carry out dredging with cofferdam method in its branches, which amounts to 95,000 m3. In low flow season, the water in the river will be diverted by cofferdams which will be constructed in stages. The water within the cofferdam will be pumped out into the river couser downstream of the cofferdam so as to ensure the air dry of the sediments exposed. Mechanical method will be used to dredge the sediments when they are dried. Tankers will be used to transported to Xiangshan Landfill. As the pumps to be used are in small size, the noise from the pumps is minor, and will not affect the surroundings. The sediments will transport to the Xiangshan Municipal Sanitary landfill site to be used as cover soil.
(2) Solid waste
38
This project will balance the earth work in excavation and filling, without any need to set up borrow area or spoil ground. The earth from slope cutting and revetment could be used in the dike enforcement. The construction solid wastes are mainly the construction waste from the demolition of the 5 pumping stations, which the estimated area of demolition is 1000 m 2, the waste slag index from demolition area is 1350kg/m2, so the estimated construction slag is 1350t. The waste slag will be transported to the third construction slag deposition field, which located in the upstream area of Cihu river, 12km away from downstream.
(3)Domestic garbage
Within construction time, domestic garbage will be produced by workers in their daily life. Without timely disposal, it will become a home for mosquitoes, odour and diseases under suitable conditions, bringing extremely bad influence to the surrounding. Consequently, in order to avoid adverse impact on the surrounding environment, domestic garbage shall be stacked at fixed place instead of mixing with building waste, and should be delivered to places designated by sanitation departments to be transported timely. Assuming that 1.0kg of garbage is produced by each worker every day, and the total amount produced during the construction arrives at 531t, seeing Table 3-3 for details.

5. Impact on ecological environment
The influences on the ecological environment within construction period fall into the following four aspects: firstly, disturbance and damage to soil and plants caused by the trampling of machines, vehicles and workers during watercourse dredging and widening, pumping station construction and so on; secondly, change of land use patterns resulted from temporary or permanent land occupation; thirdly, reduction of farming and vegetation area due to land occupation, which will have a negative effect on agricultural production; and finally, certain soil erosion may happen if re-vegetation fails in temporary occupied area.
39
6. Impact on social environment
This project doesn’t involve housing demolition and relocation. The main impacts of immigration are the acquisition of collectively-owned and national-owned land. The total land acquisition are 1788.89 mu., including 1253.89mu. collective-owned land, which are all non-prime arable land. The permanent land acquisition of national-owned land is 535 mu., which are all unused land along the river and branches. According to Measures for Land Expropriation Compensation and Resettlement in Ma’anshan Municipality, compensation will be made to the affected persons.
3.3.2 Analysis of pollution sources during operation
Since this is a water environment improvement project, no waste gas or wastewater will be produced during operation. And the impact on surrounding environment comes from the operation noises of pumping stations.
This project plans to demolish and re-construct the five pumping stations along the downstream of Cihu River, each of which will be equipped with 3 pumps. And the power of each pump in Tongyi (No.2), Zhaoming, and Xiaonanwei pumping stations will come to 250kw and that in Sulfuric Acid Plant and Tailai 180kw. In the operation of pumping stations, noises mainly come from the operation pump motors, the noise intensity of each of which ranges between 75 and 85dB (A).

Chapter IV Regional Environmental Overview4.1 Overview of Natural Environment4.1.1 Geographical Location
Located in the easternmost region of Anhui Province, Ma'anshan Municipality spans both
sides of the Yangtze River, bordering on two capital cities of Nanjing and Hefei. It is located
between 31°46'42''~31°17'26'' north latitude and 118°21'38''~118°52'44'' east longitude.
As the longest tributary of the Yangtze River within Man’anshan Municipality, Cihu River
originates from Laomai Xian of the urban district’s eastern hilly regions, flowing from east to
northwest through Xiangshan Town, Huoli Street and Cihu Village and meeting the Yangtze
River at northern foot of Cimu Mountain. The tributary has a total length of 26.1 km and a
drainage area of 124.8 km2. From around Donghuan Road to the river mouth, the main stem
has a length of about 14km and joined by such branches as Wumushan River, Qiaoshan Ditch
and Tianran River during its flow path. See fig. 1-1.
4.1.2 Topography and Geomorphy
The topography of Ma’anshan Municipality is high in east and low in west. The terrain is
basically divided from east to west into three parts: eastern hilly areas with peaks’ heights of
about 160 to 200m, western riverine areas distributed with low hills and middle fluvial plain
which is relatively flat and wide with an average altitude of around 10m. Long and narrow
terraces and washland are located between the western low hills and the Yangtze River. There
is also sandbar in the Yangtze River. Networks of lakes and ponds (Yanghu Pond,Yushan
Lake, etc.) intertwine with buttes (Yushan Mountain, Jiashan Mountain, etc.) among them,
forming the landscape of “lake and mountain each sharing half of the city’s landscape”.
4.1.3 Geo-technical Condition and Hydrogeology
1. Engineering Geology
Located in the middle piece of Ningwu fault basin from the geological structure perspective,
and Ma’anshan Municipality is also located in the midsection of the Ningwu volcanic basin.
The basin floor is composed of the Qinglong limestone of middle and lower triassic series, the
Huangmaqing group sand shales of upper triassic series and the Xiangshan group sandstones
of middle and lower Jurassic series. The upper part is composed of volcanic series at the
phase of Yanshan. Most of the current geomorphic units are quarternary, which can be
generally divided into Yangtze floodplain, first terrace, second terrace and paleogully.
41
Figure 4-1 Geographic Map of the Project Area
The quarternary strata are widespread in Cihu River basin and the quarternary new
alluviums are widespread in riversides and mountain alluvial plains with dualistic structure.
The geomorphic unit of the basin’s northern section (with the intersection between Cihu River
and Tianran River as the boundary) is Yangtze high flood plain and that of the basin’s
southern section and Lijianwan Groove is the transitionary part from the Yangtze first terrace
and paleogully to the second terrace.
2. Hydrogeology
Th groundwater of Ma’anshan Municipality is generally located in sand aquifers with the
depth of about 2m. Under the sand bed is silt stratification with the largest water content. The
groundwater level changes from season to season, ranging from 0.2 to 0.5m. The general
flow direction of groundwater is from the high geographical east towards the low west and
finally into the Yangtze River.
Besides the artificial plain fill, most of the body soil on Cihu River bank is the quarternary
new century alluvium. Except that the body soil on the bank is perched water, most of the
groundwater is phreatic water. The ③-1 layer of Cihu River bank is fine sand with light silty
soil layer which has better water permeability.
Recharge sources of the upper monimolimnion of the bank body soil are precipitation and
infiltration in river’s high flow period. Way of drainage is evaporation, infiltration or
scattering around with no obvious seasonal changes and no water level during rainless period.
42
4.1.4 Climate and Weather
Located in the northern subtropical zone, Ma’anshan Municipality has the subtropical
monsoon moist climate with four distinct seasons, marked monsoon featuring mildness and
humidness and concentrated plum rains. It has features of a short frost period, long duration
of sunshine and abundant rainfall.
1. Precipitation
The precipitation has strong seasonal variations and uneven distributions in area and time.

② Monitoring indicators
There are 25 surface water monitoring indicators, including water temperature, pH,
Dissolved oxygen, Permanganate index, COD, BOD, ammonia nitrogen, total phosphorus,
total nitrogen, volatile phenol, cyanides, arsenic, hexavalent chrome, fluoride, copper,
mercury, selenium, lead, zinc, cadmium, petroleum, anionic surfactant, fecal coliform and
61
sulfides.
③ Monitoring and analysis methods
The sampling method and the analysis method were gained from the ‘Water and wastewaters
monitoring and analysis method (Fourth edition).
2) Present situation evaluation of environmental quality
① Evaluation criteria
The Class V standard of the Environmental quality standard for surface water (GB3838-
2002) applies.
② Evaluation results
Based on the results in Table 4-13 and Table 4-14, the water quality of the Cihu River and its
branch water systems in 2011 was as follows:
Cihu River: In 2011, ammonia nitrogen and total nitrogen were over-standard in the upper
Cihu River; COD, BOD, ammonia nitrogen, total phosphorus, total nitrogen, anionic
surfactant and fecal coliform were over-standard in the middle Cihu River; COD, BOD,
ammonia nitrogen, total phosphorus, total nitrogen, anionic surfactant, fecal coliform and
cadmium were over-standard in the lower Cihu River.
Branch streams of the Cihu River: In the upper Cihu River, all indicators of the Gaocun
branch stream met the Class V standard, except that ammonia nitrogen, total nitrogen and
fecal coliform of Qingshuitang branch stream were over-standard, and COD of Huoli branch
stream were over-standard; in the middle Cihu River, permanganate index, COD, BOD,
ammonia nitrogen, total nitrogen and fecal coliform of the Wumushan River branch stream
were over-standard; COD, ammonia nitrogen and total nitrogen of the Tianran River branch
stream in the lower Cihu River were over-standard.
Except that the Gaocun branch stream met the Class V standard, the water quality of the Cihu
River, Qingshuitang branch stream, Huoli branch stream, Wumushan River branch stream and
Tianran River branch stream falls into sub-Class V, and the main over-standard indicators are
permanganate index, COD, BOD, ammonia nitrogen, total nitrogen and fecal coliform, while
all pH values meet the standard, showing that the Cihu River and its branches are affected by
domestic sewage and non-point pollution sources.

4.4.5 Sediment monitoring
1. Monitoring option
(1) Monitoring points: According to the site survey, there are only three drainage outlets in the downstream of Cihu river. Due to lack of historical data on the quality of the sediments in the river of Cihu, three sampling sites were selected on the upper, middle and lower reach of the river respectively to under stand the actual contamination status of the sediments. According to the Water and Wastewaters Monitoring and Analysis Method issued by SEPA which requires to select the sampling points at the same location of the surface water monitoring points, and it is found that the sediments are evenly distributed, therefore only one sampling point is located at the upper, middle and lower reach respectively with on columnar samples on each sampling point. see detailed in table 4-15.
Table 4-15 Sampling points of the sediment
No. River section Location
2-1# Up stream of Cihu river Huabanqiao
2-2# Middle stream of Cihu river Fengqiao
2-3# Down stream of Cihu river Beihuanluqiao
(2) Analysis items: Cadmium, mercury, arsenic, copper, lead, hexavalent chromium,
(3) Sampling time and frequency: December 9, 2012. Sampling frequency: once.
(4) Sampling and analysis method
The sampling method was in line with the ‘Water and wastewaters monitoring and analysis
method.” The 0-50cm sediments was sampled using columnar sampler and sealed into plastic
sample box, then labelled and delivered to the libratory. The collected samples are air dried
and the method of coning and quatering is used to get the desirable quantity of the samples for
lab analysis. The analysis method is attached in the annex table.
2. Sediment assessment
(1) Assessment standard
Firstly, the heavy metal content in the samples is analyzed in line with the Ambient Soil Quality Standard (GB15618-1995), which classified the standard for three kinds of uses, as follows:
Class I: applicable to the natural reserves, centralized drinking water sources, tea garden, ranch and other areas under special protection; this class is designed to protect the regional natural ecology and ensure the natural background soil quality be maintained;
Class II: applicable to the ordinary areas such as cropland and vegetable farm; this class is designed to safeguard the agricultural production and the human health; and
Class III: applicable to the forests and the areas with large capacity accommodating pollution loads, such as the land near ore mines (except for vegetable farm); this class is designed to safeguard the growth of forests and plants.
70
The analysed results are compared to the Ambient Soil Quality Standard. If the analyzed results are found to be within the limit of the parameters in the standard, the sediments can be reagarded as non-toxic materials, and the analyzed results will be compared with the Pollutant Control Standard for Sludge for Agricultural Application (GB4284-84), the Sludge Quality for Municipal Landscaping, for Municipal Sludge (CJ 248-2007), and Mixed Sludge Quality for Landfill, Municipal Sludge (CJ/T 249), so as to determine the options for use of the sediments in agricultural, municipal landscaping and forestry.
Secondly, if the analyzed results are found to be over the limits of the parameters of the standard, it can be concluded that the sediments are toxic and can not be used in agricultural, municipal landscaping and forestry. So a detailed protocol for testing the toxicity of the sediments should be developed and the treatment and disposal of the sediments should be in compliance with the relevant requirements for management of hazardous materials.
(2) Assessment results
Comparison with international standards
In China, the Ambient Soil Quality Standard is used to evaluate the toxici level of the sediments so as to determine whether the sediments are hazardous materials or not. To further understand the relevant standards in developed countries in the screening of soils, Comparison with the standards in developed countries are made as follows:

These SSLs ( Soil Screening Levels) alone do not trigger the need for response actions or define “unacceptable” levels of contaminants in soil. The “screening” refers to the process of identifying and defining areas, contaminants, and conditions, at a particular site that do not require further Federal attention.
From Table 4-16-1 and 4-16-2, it can be seen that the Cd in the Chinese standard which is easily taken by plants and concentratedn in the reproductive parts such as flower and fruits that will pose the serious risk of health to people who ingest them is much lower that in the SSLs in USA and Dutch. The As in Chinese standard is much lower than that of Dutch but much higher than that in the USA. Other heavy metals limits in Chinese standard for Class III are equivalent to Dutch SSLs, but much lower than the USA’s SSLs.

detected in the sediment monitoring of Cihu river. The tested results of mercury is between 0.469 and 1.17mg/m3, arsenic is between 16.8 and 19.0mg/m3, copper is between 32.7 and 109mg/m3, lead is lower than 112mg/m3.
Comparing to the Soil environment quality standard (GB15618-1995), the monitored mercury exceed the Class II standard, and the monitored Mercury and copper also exceed the Class II standard at middle stream, however, reach the class III standards. The pollutants at the downstream sediments reaches class II. So the sediments are not toxic or hazardous material, will lead no harm to the plants and environment.
The analyzed results also indicate that with the operation of the industrial wastewater treatment facilities and municipal wastewater treatment plants, as well as the regular dredging works in Cihu River basin, the water quality in the river has been improved to some degree.
4.5 Environmental issues of the Cihu River basin
4.5.1 Flood control and drainage
1. Present situation of flood control and drainage
(1) Present situation of river dikes
1) Upper Cihu River
The upper Cihu River refers to the stretch from its origin to East Ring Road, about 13.1km long, in which the stretch from Provincial Highway 313 to East Ring Road segment is about 6.7km long. Only the Donghewan segment about 600m above East Ring Road in the upper Cihu River has flood protection dikes, as shown in Figure 4-9.
Figure 4-9 Present situation of the upper Cihu River channel
73
2) Middle Cihu River
The middle Cihu River refers to the stretch from East Ring Road to Linli Road, about 6.7km long, with dikes on both banks, as shown in Figure 4-10.
Figure 4-10 Present situation of the middle Cihu River channel
3) Lower Cihu River
The lower Cihu River refers to the stretch from Linli Road to the river entrance, about 6.3km long, with dikes on both banks, as shown in Figure 4-11.

(2) Present situation of Lijianwan river
Lijianwan river inward to the Cihu river at the upstream 300m of the river mouth, Lijianwan river is the boundary river of Anhui an Jiangsu province. The right river embankment which belongs to Jiangsu reaches the standard after the renovation. The left River embankment which belongs to Anhui is soil embankment, mostly covering by weed, without any artificial protection facilities.
Figure 4-12 Present situation of Lijianwan river (left side belongs to Jiangsu Provice, the right side belongs to Anhui Province, in the photograph)
(2) Present situation of storm water drainage
1) Present situation of storm water drainage system
The Cihu River is a river connected naturally to the Yangtze River, with a basin area of
75
124.8km2. The catchment area can be divided into a hilly area and an embanked area. The hilly area is relatively high in level, with a total area of about 81.0km2, with no dikes on both sides, in which storm water runoff can be drained into the Cihu River by gravity. The embanked area is in a low-lying plain, with a total area of about 43.8km 2; many natural canals and ponds in this area are connected to the Cihu River, and there are dikes on both sides of the river channel. Since the dikes cut off the connections between the Cihu River and the natural canals, flood drainage pumping stations are used to drain storm water into the Cihu River.
2) Present situation of flood drainage facilities
There are 24 flood drainage pumping stations on both sides of the Cihu River, in which 8 were built in the 1980s, 13 in the 1990s (including renewal) and 3 after 2000, as shown in Table 4-3. In addition, the Cihu pumping station for storm water discharge for the Cihu River is located beside the Cihu sluice on the Cihu River, with a design flow rate of 10.0m3/s and an installed capacity of 465 kW, completed in 2009.
In 2009, a controlling sluice gate (Cihu sluice) and a river pumping station (Cihu pumping station) were built at the entrance of the Cihu River. When the water level of the Yangtze River is low (less than 11.15m, Wusong sea level), the Cihu sluice opens, so that storm water in the Cihu River can flow into the Yangtze River by gravity; when the water level of the Yangtze River is high (above 11.15m, Wusong sea level), the Cihu sluice is closed to prevent floods in the Yangtze River, and storm water in the Cihu River is pumped into the Yangtze River via the Cihu pumping station.

(3) Present situation of branch streams
The branch streams, in the middle and down streams of Cihu river basin, are the major composition of the urban rainwater system. These branch streams play important roles in urban drainage. Nowadays, some branch streams shrink, diverted or even disappeared during the urbanization process. The branch streams still existed and managed by the city are shown in table 4-20 and figure 4-13.

4.5.2 Existing problems
The dikes of the Cihu River have taken form after many years of construction, and the flood control capacity has improved, but can just resist floods that occur every 10 years. In recent years, there have been 19 dangerous cases with the dikes of the Cihu River, including cases of seepage and water creep, 4 cases of landslide, two cases of cracking and one case of leakage. The main existing problems include:
(1) Low flood control standard: The dikes of the Cihu River have not been subject to systematic reinforcement and are generally of poor quality, loose and irregular land filling.
(2) Many risky segments: During the flood season, the dike bodies and bases generally have dangerous cases of seepage and water creep. Behind most segments of the dikes, deep ponds are densely distributed and the side slopes are steep, affecting the safety of the dikes. The culverts, sluices and gates on the dikes are mostly in masonry structure, and were built in the 1960s-70s, with leakage present extensively.
(3) The dike-penetrating buildings are aged and leaking: The culverts and sluices built in the 1950s-80s have been operated for tens of years, and their masonry bodies or materials
81
have been seriously weathered, resulting in water leakage, reduced structural strength, mortar disengagement or brick loosening. The reinforced concrete box culverts are also seriously aged.
(4) Reduced rainfall regulation: During the urbanization process, the existing natural drainage system has been damaged, reducing rainfall regulation capacity.
(5) The urban drainage system is unsound, and some parts were not constructed or updated in strict conformity with the drainage plan during construction, so that some storm sewers can not meet the standard.
(6) Insufficient flood drainage capacity
The design standard of the flood drainage pumping stations is low. With the urbanization of the city, rainfall runoff has increased sharply and is excessive for the flood drainage capacity of some flood drainage pumping stations in this area.
4.6 Survey of pollution sources in the Cihu River Basin
According to the survey, the main pollution sources include the upstream mining, industries, Xiangshan landfill, domestic sewage and non-point pollutions. In order to improve the water environment quality of the Cihu River, the Ma’anshan Municipal Government has taken measures accordingly. The completed water pollution management facilities include wastewater treatment systems, the leachate treatment facilities of the Xiangshan landfill, the acid leachate management project and the Upper Cihu River Surface Water Management Project, as shown in Figure 4-15 to Figure 4-18.
Figure 4-15
4.6.1 Mines in Upstream Area
The upper reach area of Cihu River is an iron ore mining area, where iron ore is shallowly buried and suitable for open-pit mining, with an average grade of 25%-30%, and the major mining areas are Gaocun, Xiaonanshan and Luoboshan, as shown in Figure 4-16. The non-point source pollution in the mining area is mainly the wastewater from open mines, leachate from tailing reservoir, washwater from ore dressing industries and overflow water from tailings ponds. Since iron ore is often associated with a variety of metals and sulfides, a variety of heavy metals will be leached out under the joint action of air, water and bacteria. Mine wastewater is highly acid and will pollute the Cihu River.
Figure 4-16
1. Mining enterprises
There were 24 mining enterprises in operation in Ma’anshan Municipality in 2010, including
82
state-owned and private enterprises. The state-owned enterprise is Magang Group, which transports iron ore by railway mainly and by highway as an auxiliary means; private enterprises transport iron ore mostly by highway, as shown in Table 4-21. All mining and ore-dressing enterprises in the upper Cihu River have been closed down.

2. Industrial pollution control
Before 2006, the main enterprises in the Xiangshan Industrial zone were Dongsheng Chemical Plant, Wensheng Chemical Plant, Yujiang Chemical Plant and Donghai High-molecular Material Factory, producing sulfuric acid and related products mainly. Due to these enterprises had no wastewater treatment facility or the existing facility was aged, the Cihu River was polluted. In 2008, the Ma’anshan Municipal Government closed down Dongsheng Chemical Plant and Donghai High-molecular Material Factory permanently, and improved Wensheng Chemical Plant and Yujiang Chemical Plant. Industrial wastewater recycling has been realized after their improvement, and these two enterprises are now operating properly.
(1) Ma’anshan Donghai High-molecular Material Factory
This factory was put into operation in 2006, and produces 6-nitryl-1 mainly, with a design capacity of 800t and an annual output of 600t. This plant has no wastewater treatment facility and has not realized storm-sewage separation, and its sewage outfalls have not been regulated, so this factory was closed down permanently in 2008.
(2) Dongsheng Chemical Co., Ltd.
This enterprise was put into operation in 1994, with a design annual capacity of 60,000t of concentrated sulfuric acid, and its actual output was 46,000t of sulfuric acid in 2007. This enterprise produces waste gas (acid mist, flying dust), noise and wastewater that affect the ambient environment greatly, and was closed down permanently in 2008.
(3) Ma’anshan Wensheng Chemical Co., Ltd.
89
This enterprise produces amino-C-acid mainly, with a design capacity of 600t/a. This enterprise has no wastewater treatment facility and has not realized storm-sewage separation, and its sewage outfalls have not been regulated. Industrial wastewater recycling has been realized after its improvement in 2008, and this enterprise is now operating properly.
(4) Ma’anshan Yujiang Machinery & Chemical Co., Ltd.
This enterprise was founded in 1998, and produces 800t/a of peri-acid and 300t/a of Laurent's acid. This enterprise has no wastewater treatment facility and has not realized storm-sewage separation, and its sewage outfalls have not been regulated. Industrial wastewater recycling has been realized after its improvement in 2008, and this enterprise is now operating properly.
3. Present situation of discharge ports
Industrial wastewater is discharged into the Cihu River via 3 outalls, and all in Magang New Zone, as shown in Figure 4-22.
Figure 4-12 Positions of sewage discharge ports of Magang New Zone
Currently, an online automatic wastewater monitoring system has been installed in Magang New Zone to monitor wastewater discharge and pollutant levels. It can be seen from the monitoring results (see Table 4-25) that all pollutants in wastewater from Magang New Zone meet the Class II standard of the Integrated wastewater discharge standard (GB8978-1996) after treatment.

4.6.3 Xiangshan Municipal Sanitary Landfill
The Xiangshan Municipal Sanitary Landfill is located on the obsolete tailings pond of the Xiangshan troilite mine, and broke ground in 1985. Its area was initially 4.3hm2 and expanded to 19hm2 in 2000. Currently, the landfill treats over 300 tons of domestic waste daily.
The leachate is derived mainly from rainfall, surface runoff, and decomposition of waste under microbiological action. Different from ordinary wastewater, waste leachate features high BOD5, COD, metal and ammonia nitrogen levels, great fluctuation of quality and amount, and disproportional biological nutrients.
In 2004, the expanded and improved Xiangshan landfill was put into operation. It has a lining system, leachate collection system and landfill gas collection system, with a design daily capacity of 400t of waste and 120t of leachate. An EIA report was prepared for this landfill in August 2004 and has been approved.
The leachate treatment facility employed “a regulating pond + a 3-stage mineralized bio-reaction bed and a biological aerated filter”, and was put into operation in 2005. Tail water is drained into branches of the upper Cihu River, and design water quality meets water pollutant discharge standard of the Pollution control standard for domestic waste landfill (GB16889-2008). However, with the increase of treatment demand, the treatment capacity of leachate treatment facility is no longer sufficient.
In 2009, the Xiangshan Landfill Domestic Waste Leachate Treatment Expansion Project was implemented in Ma’anshan Municipality, with a design capacity of 150t/d. This project was put into operation in July 2010. An EIA report was prepared for this project in January 2010 and has been approved.

4.6.4 Other pollution sources
In addition to leachate from mines, industrial enterprises and landfills, the Cihu River is also polluted by domestic and farmland non-point pollution sources.
The main reason for domestic pollution is that the sewer network of the Cihu River basin is unsound, and domestic sewage is drained into the branch water system of the Cihu River locally, resulting in river pollution. The municipal facilities of some communities are not complete, and sewers have not been repaired timely after damage, so that community domestic sewage is drained into the branch water system, resulting in river pollution.
There is also vast farmland on both sides of the Cihu River and its branches, and non-point source pollution from pesticides and fertilizers may also pollute the Cihu River.
4.7 Water pollution management facilities in the Cihu River basin
1. Overview of sewage works in Ma’anshan Municipality
According to the Urban Drainage Engineering Plan of Ma’anshan Municipality, there are 6 sewage collection systems in the urban area, which are Cihu, Wangjiashan, East New District, Shatang, North Development Zone and South Development Zone.

4. Existing problems of sewage collection systems
96
Currently, the rainwater pipe system in the Cihu river basin is a separate system. Since the sewer network is still not complete, some sewage is still not collect and treated by WWTPs but discharged directly into the branch water system of the Cihu River, resulting in pollution:
The service range of the Cihu WWTP is a newly developed area. According to the urban development plan of Ma’anshan Municipality, sewers under urban roads will be laid along with road construction, so that some sewage is not treated by this WWTP but drained directly into the branch water system of the Cihu River, resulting in river pollution.
The service range of the Wangjiazhuang WWTP is a relatively developed area, where the drainage system is complete, but some places are still not covered by the sewer network, so that some sewage is not treated by this WWTP but drained directly into the branch water system of the Cihu River, resulting in river pollution.
The service range of the East New District WWTP is towns in the upper Cihu River and Xiushan New District, where the sewer network is under construction, so that some sewage is not treated by this WWTP but drained into branches of the Cihu River, resulting in river pollution.
5. Existing sewer network and construction plan
To date, sewers with a total length of 145.6km have been laid in the Cihu River basin. It is planned to complete the whole sewer network of the Cihu River basin by 2015, with a gross investment of RMB41.9085 million, to be funded and constructed by the Ma’anshan Municipal Government. See Table 4-31.

5.3 Impacts of Land Acquisition and Resettlement
The requisition of land covers 1,230 mu (a unit of area ,one mu=0.0667 hectares ). The demolished houses are about 177800m2 with about 3,300 people.
According to the ‘Resettlement plan of Ma'anshan Cihu River Basin Improvement Project’ compiled by the Immigrations Center of Hehai University, the findings are as following:
(1) The permanent land occupations of national-owned land are 48.59 mu, which should transfered to the construction unit for free. Thus means, the land occupation does not involve land acquisition and resettlement.
(2) The newly acquisition of collectively-owned land of 475.7 mu, including agricultural land of 299.27 mu.( arable land 200.18mu.), construction land of 176.43 mu., will affect 71 households, 306 persons. The acquisition of collectively-owned land obey to the ‘Compensation and resettlement of land acquisition of Ma’anshan municipality (Ma’anshan People’s Government 43)’.

Chapter VI Comparison of Alternatives
6.1 Analysis of With and Without Project
Currently, the project area is facing issues like low ability of flood prevention and urban drainage, serious river channel sedimentation, etc. The frequent occurrence of flood disasters has brought great negative impacts on the stability of local residents. This project will establish a complete system of flood prevention and urban drainage for the project area. However, the construction of the project may bring some adverse effects like occupation of land, resettlement, contamination during construction period, etc.
From the perspective of environmental profit and loss as well as social economy, to compare and analyze the alternatives of with and without project, see Table 6-1 for details.
Table 6-1 Zero Option Comparison Analysis
Description With project Without project
Advantages ①The ability of flood prevention and water logging control is improved, and the average flood control benefits of several years in the project area are RMB 75.42 million Yuan;② Promote the development of regional social economy;③ Improve the situation of ecological environment and investment environment;④ Promote harmonious development between people and environment.
Maintain the current environment situation, no environmental contaminations produced from project construction.
Disadvantages
①Occupation of land resources;②Short-term adverse effects on the environment caused by project construction and migrant resettlement.
Frequent Water logging situation is not improved, bringing huge losses of social economy;
Overall analysis
From social and environmental perspectives, the alternative of with project is better than the alternative of without project.
According to Table 6-1, though without project alternative has no impacts on the environment, residents of the project area still suffer from flood disaster, and water pollution still increases, influencing life quality of residents and economic development; with project alternative may bring some adversde environmental impacts, but they can be avoided and reduced through relevant environmental mitigation measures. Besides, the environmental contamination of the construction period is temporary, while the social and environmental benefits of the project is permanent. Therefore, from the social and environmental perspective, with project alternative is better than without project alternative, and the project construction is necessary.

6.2 Analysis of Different Technical Options
6.2.1 Comparison of revetment option
Taking the revetment way of Cihu River upstream as an example, the assessment compared and analyzed the two ways of mortar rubble revetment and ecological revetment.
1. Option I (mortar rubble revetment)
The option mainly aims at bank stabilization and rapid discharge.
The river channel will use trapezoidal cross-section; the two sides of the stream channel cross-section will use mortar rubble revetment; riverbed bottom will use permeable lining, to which rock block (50cm in thickness) will be thrown after excavation, covered with geogrid and then 30cm –thickness rubble in upper position, to maintain the hydraulic connection between the river and the underground water outside the river channel.
2. Option II (natural revetment)
This option mainly aims at bank stabilization as well as flood detention and drought release.
The river channel will use compound cross-section combining the main channel with the beach. Build beaches on both sides of the main channel, and build wetland or conduct greening in the beaches; Natural revetment is used to protect the riverbanks and ecological environment by solid fixation plants with developed roots.
3. Option Comparison
Option I: In option I, the cross-section is simple, stable and scour resisting with low land occupation. The upstream area may not easily suffer from water logging due to the rapid discharge, but the downstream consequently bears great discharge pressure. The option uses mortar rubble as materials, cutting off the ecological exchanges between land and water. Riparian plants can hardly grow, damaging the biologic chain in the river and influencing the self-purification ability of the river channel. After management, the river loses the functions of ecological corridor, not in harmony with the surroundings.
Option II: Compared with Option I, Option II has larger land occupation and investment. However, this option boasts good effects in flood control, eco-environmental protection, self-purification of water and so on, specifically introduced as follows:
(1) Flood prevention effects
The plants of the ecological revetment can be used to regulate the conditions of surface and underground water, which will make some changes in the water cycle channels. When flood comes, water will penetrate into the dyke and be stored through the plants on the surface of the revetment, which can weaken the flood peak, delaying the runoff. When drought season comes, the water stored in the dyke will in turn penetrate into the river, playing a positive role in adjusting the water volume. Meanwhile, the ecological revetment uses large amount of soil fixation plants with developed roots, which has good effects in water and soil conservation, strengthening the anti-scouring effects of the revetment.
(2) Ecological effects
Ecological revetment can combine the water and river channel with the dikes and riverside
104
plants, forming a complete river ecological system. Plants on the revetment can change the current speed, which will bring places of foraging, habitat and refuge for aquatic animals and amphibians, and will thus have positive impacts on maintaining biodiversity. This option can also provide rest and entertainment sites for people, improving the overall taste of the city.
(3) Self-purification effect
The water plant of the ecological revetment can absorb inorganic salts nutrients from the water. The developed roots are also medium for microorganism to adsorb, which will promote the process of water purification and thus improve the water quality.
All in all, although Option II has larger land occupation and investment compared with Option I, it has obvious advantages in flood control, eco-environment protection and even the value of the surrounding land. Therefore, we recommend Option II.
6.2.2 Comparison of dredging option
The upstream of Cihu river was dredged with hydraulic way in 2009. Based on the local circumstance and the upstream dredging experience, this project plans to apply hydraulic dredging on the downstream and cofferdam dredging on the branches. See the detailed comparison in table 6-2.
Table 6-2 comparison of dredging options
Items Cofferdam dredging Hydraulic dredging

Suitable to the rivers with perennial water
Land occupyPile along the river on the bank, small land occupy
Large land occupy, need to setup special yard
Environmental impacts
Small land occupy and vegetation damage.
Large land occupy and vegetation damage.
Based on the table 6-2, the cofferdam dredging will occupy less land and affect less on the environment. However, due to the restrict of engineering requirement, it is difficult to apply cofferdam dredging on the downstream of Cihu river, where the water level is around 4-5m. So this project plans to apply hydraulic dredging on the downstream and cofferdam dredging on the branches. And the applied options are reliable.
6.2.3 Sediment disposal option analysis
Considering the features of the dredged sediments, different option of sediment disposal are analyzed.
1. Option 1（used on farmland）Applying thel dredged sediment as organic fertilizer on the farmland, to improve the soil
105
condition, had been adopted in many counties and regions. Using the dredged sediment will add some heavy metal elements into soil, as well as the crops. However, the sediment which reached the standard could be useed to planting crops.
The monitored indices of the sediment in this project reach Class II level of Soil environment quality standard (GB15618-1995) and limit of maximum permissible content in the pollutant control standards of sludge for agricultural application(GB4284-84). It means the sediment could be useed in the farmland, after strictly monitoring and inspection. See detailed in table 6-3.
However, the residents and farmers are worrying that the application of sediments on farmland would affect to the crop quality and production. So, they do not support the application of the sediments in farmland.
Table 6-3 Comparison between sediment quality and agricultural sludge control standards
Monitoring item Monitoring resultsThe pollutant control standards of

Mercury（mg/kg） 0.469 ≤15
Arsenic（mg/kg） 16.8 ≤75
Copper（mg/kg） 32.7 ≤500
Lead（mg/kg） Not detected ≤1000
Cadmium（mg/kg） Not detected ≤20
Hexavalent chromium（mg/kg） Not detected ----
2. Option 2 (use in landscaping)The monitored indices of the sediment reach Class II of Soil environment quality standard (GB15618-1995) and the Urban Sewage Sludge Disposal - Landscaping Quality (J248-2007), see table 6-4.
This project will landscape the ecological revetment on Cihu river and branches within blue lines, where 25m width dike on both sides of Lijianwan river and 3m width dike on both sides of all branches would be vegetated. The ecological revetment and greening may needs fertile soil. So, the sediment could be used for the ecological landscaping.
However, the landscaping and greening using sediments could risk the people’s health, by pathogens, germs and odors. In the public consultation, local residents were also against the utilization of sediments on landscaping and greening.

3. Option 3 (Cover soil of Xiangshan landfill)
Xiangshan landfill is located in the Tao village of Xiangshan county (upstream of Cihu river), 14 km to downtown, with a total capacity of 2.93 million m3, design capacity is 400 t/d. And at present, this landfill treat domestic garbage 300 t daily. The pollutants in dredged sediments meet the standards of landfill cover soil in ‘Urban sewage sludge disposal - Mixed landfill quality (CJ/T 249)’. The sediments could transport to the Xiangshan landfill site to be used as the cover soil. See detailed in table 6-5.

Lead（mg/kg） Not detected <1000
Cadmium（mg/kg） Not detected <20
Hexavalent chromium（mg/kg） Not detected <1000
4. Analysis of option comparison
Based on the analysis of sediments monitoring results, the dredged sediments could be used on farmland, landscaping and as cover soil in landfill. However, during the public consultation, local residents are worrying about the impacts on human health of the sediments usage on farmland and landscaping. The local residents do not agree with the option 1 and 2. And the risks to health and environment are low and the techniques are reliable of option 3 in the public’s opinions.
So to sum up, the option 3 is recommended in this project to use the sediments as cover soil of landfill.

Chapter VII Environment Impacts Analysis and Mitigation
MeasuresIn construction period, fugitive dust, odour, noises, sewage, and sediments influence the surroundings and ecological environment; In operation period, noises of drainage pumping stations influence the surrounding sound environment.
7.1 Environment Impacts Analysis and Mitigation Measures
7.1.1 Ambient Air
1. Analysis of the Ambient Air Impact:
In construction period, the pollution elements include odour, fugitive dust in construction and a small amount of waste gas in construction.
(1) Analysis of odour pollution
The odour appears in the process of watercourse dredgeing. In the watercourse, when the organics elements in sediments is disturbed or lies on the ground, the odour (mainly ammonia and hydrogen sulfide) will release in amorphous state and have a negative effect on the surroundings. In addition, the transportation of sediment from the watercourse can produce odour.
According to features of this project and surroundings, this estimation refers to the secondary standard of Emission Standards for Odor Pollutants (GB14554-93).
1) Classification of odour intensity grades
The classification of odour intensity grades is based on the detection threshold. Nowadays, odour intensity is divided into 6 levels in China. See Table 6-1. The restriction generally equals to odour intensity levels 2.5~3.5. If beyond the range, it is considered that odour pollution has occurred, which requires to take mitigation measures.
Table 7-1 Classification of odour intensity
Classification of intensity Odour smelling intensity
0 Odour free
1 The odor could be smelt barely. (Detect threshold concentration)
2The property of weaker gas can be determined (make sure the threshold concentration )
3 The odour could be smelt easily.
4 The odour could be smelt quite easily.
5 Intense smell
2) Analysis of odour influence
This evaluation adopts analogy method, analyzing and determining the intensity level of odour pollution. Refer to Mudanjiang Nanbaozi Dredging Project. The survey of its odour level sees Table 6-2.
109
Table 7-2 Odour Intensity Chart of Mudanjiang Nanbaozi Dredging Project
Distance Odour smelling intensity Level
Shore With obvious odour Level 3
Bank side 30m Slightly Level 2
Bank side 80m Very slightly Level 1
Beyond 100m None - Level 0
Nanbaozi is situated in the southeast of Mudanjiang Municipality. It is the river channel that discharges and contains contaminants. Because of wantonly emission of domestic sewage, the water quality has been deteriorated severely. Now it failed to meet the Class V water quality standard. The river channel is cleared with dry method in summer. From Table 6-2, it could be seen that beyond 30m of the watercourse, there is slight odour during dredging, and the odour intensity of which is about level 2, lower than the restriction of odour intensity; beyond 50m, odour could be smelt rarely. During dry season, the project will adopt wet method to dredge the river. Then the sphere and intensity of influence of the sediment would be lower than that of the sediment of Nanbaozi Dredging Project. Therefore, the influence sphere from the storage yard of sediment is within 30m.
(2) Analysis of fugitive dust pollution
During the construction, fugitive dust, inevitably produced in earth-rock excavation and back-filling and delivering, loading and unloading of building materials, brings some bad effects to air environment. Especially dust produced in dreg stacking when it is windy and dry, in truck loading, and littered materials from running vehicles will cause secondary fugitive dust under the combined influence of wind and running wheels. Therefore, fugitive dust pollution in the construction process affects not only areas in this project, but also those along surrounding roads.
Fugitive dust in the construction is closely related to construction management, the climate within construction period and especially the speed of wind. Table 6-3 provides a list of measured data about dust in different construction sites from Shijiazhuang Environmental Monitoring Center.
Table 7-3 Results of dust monitoring in construction sites in Shijiazhuang Municipality Unit: mg/m3
Distance from the plant (m)
10 20 30 40 50 100 Remark
No watering on the construction site.

construction site.0.437 0.350 0.310 0.265 0.250 0.238
As Table 6-3 shows , if the site isn’t watered , the construction fugitive dust, 30 meters away from the construction site, can reach the requirement of the Integrated Emission Standard of
110
Air Pollutants （GB16297-1996 ）; with the site watering , the construction fugitive dust, 10
meters away from the construction site, may reach 0.437mg/m 3, which may meet the requirement of the Integrated Emission Standard of Air Pollutants.
(3) Analysis of waste gas pollution
Waste gas, which is mainly caused by the fuel burning of construction machinery and transport vehicles, includes smoke, sulphur dioxide, nitrogen oxides, carbon monoxide, and other pollutants. The transport vehicles discharge the most waste gas, which occurs mainly on the road. It is the line source. Since the construction equipments or the transport vehicles are mostly large machinery, the single emission coefficient is large. However, the construction equipments are less and dispersed, so the pollution intensity is comparatively slight and the exhaust gas would not cause obvious effect on the air quality in the surroundings.
2. Mitigation measures for ambient atmosphere
To protect the air quality in the surroundings, the project should take the following measures. See Table 7-4.
Table 7-4 Table of mitigaiton measures for ambient atmosphere
Bucket Name Security measures
Construction period
Pollution sources control
Odour
Dredging project should not be constructed in summer; meanwhile, the operating sphere of the storage yard of dredged materials should be controlled.And the distance from the yard to the residential buildings should be more than 30m.
Construction fugitive dust
Materials that are easy to produce dust shall be humidified or shielded with tarpaulin from wind in temporary storage.Watering over dust points and roads 4-5 times at regular time every day.Earthwork should stop in the windy days of larger than Level 4 windsStrengthen the management of transport vehicles; in the process of transportation, the materials should be sealed with tarpaulin.
Mechanical waste gas
Machines and vehicles should be chosen according to the National health protection standard, to guarantee the tail gas and smoke to meet emission standards.
Other Use commercial concrete
Protection of sensitive placesConstruction site near sensitive points shall set enclosure.
111
7.1.2 Surface-water environment
1. Environmental impact of the project construction on surface water
Sand gravels used in this project are purchased with no need for washing in construction site, and only some simple mechanical maintenance will be done on the construction site without cleaning. Therefore, the wastewater comes from the supernatent of the sediments yard and the domestic sewage of the construction workers.
(1) Supernatent of sediments yard
The main pollutant in the supernatent is SS. SS can be removed through the physical precipitation. However, as the reduction of water depth in the sediment yard, the precipitation time of the muddy water would be shortened. To avoid the secondary suspension of the SS in supernatent, before discharging into Cihu river, the supernatent should be settled in a settling tank.
The suspended matter concentration in the supernatent of sediments yard is a simulated result (See table 7-5). The suspended matter concentration reduced as the precipitation time increased, after 48 hours, the suspended matter concentration could meet the Class II of the Integrated wastewater discharge standard.

(2) Domestic sewage of the construction workers
The domestic sewage of the constructors includes the waste water of bathing, dining, washing and night soil sewage, which contain mainly fats and vegetable oils, waste food, detergent and etc. The major pollutants in domestic sewage are COD, BOD5, SS, ammonia and nitrogen. According to the analogy survey, the water quality is
COD300mg/L ， BOD5150mg/L ， SS150mg/L. The constructors could use the living
infrastructure of the nearby villages, which may have minor influences on the surrounding waters.
2. Mitigation measures of surface-water environment

7.1.3 Noise environment
1 Analysis of construction noise environment influences
(1) Serious noise source
The noisy equipment during construction is mainly from the dredging equipment and construction machinery and the vehicles that transport construction materials. The major machinery and transport vehicles are: excavators, bulldozers, sludge pumps and trucks, etc. According to the analogy survey and the data analysis, the level of noises caused by the machinery See Table 7-7.
Table 7-7 Table of level of noises caused by construction machinery
Serial No. Types of machinery and vehicles Test location (m) Noise value [dB（A）]1 Bulldozer 1 92
2 Excavator 1 92
3 Truck 1 90
4 Sludge pump 1 95
(2) Forecast Calculation
This assessment adopts the model of point-source attenuation, predicting the geometric divergence attenuation from noise source to the receipt point, without considering the noise barrier and air absorption. The forecast formula is as the follows:
Lr=Lr0-20lg(r/r0)
In the formula: Lr----A sound pressure level from noise source r, dB(A)；Lr0-----A sound pressure level from noise source, dB(A)；
113
r,r0-----Distance between the forecast point and the noise source，m，=1m.
According to the characteristics of the project construction, without considering the noise attenuation caused by barriers, plants and air, the decay of construction equipments with the change of distance see Table 7-8.
Table 7-8 Influence range of major construction machinery noises Unit: dB（A）
EquipmentSourse strength
dB（A）Noise level of forecast points of different distances
from the noise source
20m 40m 60m
Bulldozer 92 66.0 60.0 56.4
Excavator 92 66.0 60.0 56.4
Truck 90 64.0 58.0 54.4
Sludge pump 95 69.0 63.0 59.4
Because there are some sensitive points such as residential buildings and schools along the
river channel to be dredged in the project, construction is forbidden at night (22 ：00~6：00）. It could be seen from Table 6-7 that noises of the sludge pump at about 20m away from
the construction site can reach level-4 in the day, and level-2 at about 60m. So, the sludge pump should be set 60m away from the residential buildings. Noises of the other construction machinery at about 20m away from the construction site can reach level-4 in the day, and level-2 at about 40m.
(3) Forecast of construction noises at the sensitive sites
According to the survey, both sides of Wangbaitan river system Yangqiaogou, Xitang river system and south ditch of Fengshou have been embanked. This project only dredges the above 4 river systems, with the method of hydraulic dredging. The major noise source is the sludge pump, which should be at least 60m away from the residential areas.
The rehabilitation of Cihu River and its tributaries systems mainly include dredging, embankment and landscaping. According to noise forecast, when the bulldozer, excavator and other equipments work, the noises 40m away could reach the Class II of Environmental
Quality Standard for Noise （GB3096-2008）, so the impact sphere of construction noise is
40m.
This report gives forecast of the noise value at the sensitive points of noise environment in the assessment ranges, and the results are shown in Table 7-9. The noise was 61.3~92.0 dB(A) within 40m along the river which exceed the Class II of Environmental Quality Standard for Noise (GB3096-2008). So the temporary barrier should be set for the residential area and schools within 40m of the construction sites along the river, so as to reduce the influences of construction noise on the normal life of the residents and the teachers and students.

The project plans to set up the pumps in the pump room and use base countion, flexible connection at the inlets and outlets, conduct regular equipment lubrication and construct green belt surrounding the pump stations, with grass as the major, with tall arbores and low shrubs as the auxiliary. After noise reduction, the noise from pumping stations to the boundary could meet the Class III of Industrial Enterprise Emission of Noise on Factory Boundary (GB12348-2008).
Based on survey, there is no sensitive receptor such as residential area and school within 50m of the pump stations. 76m northeast of Tongyi (II) pump station is Cihu town; to the west it is next to the new district of Ma’anshan Iron and Steel Company; to the east there is a fish pond, the Nantang river system and the vegetable market; to the north there is a salvage station. Tailai Pump Station is surrounded by the ponds, the farmlands and enterprises. 200m around the Pump Station of Sulfuric Acid Plant is the vacant land .To the east of Zhaoming Pump Station is a factory; 52m to the south is the road; to the west is Cihu River and to the north is the vacant land. Xiaonanxu Pump Station is close to Dianye Road at the north, Cihu River at the west, and farmlands at the other sides.
To sum up, with the measures of wall isolation and planting taken in the drainage pump stations, the influences on the surroundings are reduced to an acceptable level.
3. Acoustic environment mitigation measures
To ensure the acoustic environment quality of the surroundings, the project should take the following measures to protect acoustic environment. See Table 6-11.
Table 7-11 Acoustic Environment Mitigation Measures
Time bucket Name Mitigation measures
Construction period
Pollution source control All construction units should arrange the construction
period reasonably, register the applications well and take necessary measures to reduce and prevent noises.
Be strict in the management of construction intensity, machinery as well as vehicle operators and operating procedures. When it is necessary, the transport vehicles could be installed with noise-abatement equipment;In the process of construction, it is better to choose low-noise equipment, maintain carefully the machinery equipments, keep good working conditions and reduce the operation noises of the equipments;
116
Lay out construction site rationally and scientifically and concentrate the fixed noise sources to reduce the impacts on environment.Fixed machinery equipment could be installed in temporary rooms at the construction sites.
Protection of constructors
Operating personnel on the sites with high noise machinery should be equipped with necessary noise protective articles. They should not work over 6 hours a day.
Protection of sensitive places
Construction time should be arranged reasonably when the construction is near the sensitive sites. It is necessary to avoid the rest time of the residents and stop working from 22:00 till 6:00 the next morning.When passing the residential areas, the transport vehicles should be driven at limited speed and the high tone loudspeaker is forbidden; transport time should be reasonably arranged in order to avoid disturbing the rest of residents with the vehicle noises.During the construction of the project, the sludge pumpshould be considered to be 60m away from the residents. The sensitive sites of residential areas and schools within 40m along the river should be temporarily blocked so as to reduce the influences of the construction noises on the normal life of the surrounding residents and the teachers and students.
Operation duration
The draining pump station should be equipped with low noise pump unit. Vibration damper should be installed at the base of the pump;Strengthen the maintenance and reservation of the water pump equipment to avoid abnormal operating conditions.
7.1.4 Solid Waste
The solid wastes of the construction mainly come from the dredged sediments, domestic garbage of the workers and the construction waste.
1. Dredged sediments
(1) Analysis of pollution levels
This project will carry out dredging with hydraulic way in the downstream of Cihu, which amounts to 77,000m3. This project will also carry out dredging with cofferdam method in its branches, which amounts to 95,000 m3. Comparing to the Class II of Soil environment quality
117
standard (GB15618-1995), all monitored sediments reaches the standards, will lead no harm to the plants and environment.
(2) Sediments management option
Four sediments yards will be setup. According to the option comparison in chapter VI, the pollutants in dredged sediments meet the standards of landfill cover soil in ‘Urban sewage sludge disposal - Mixed landfill quality(CJ/T 249)’. The sediments will transport to the Xiangshan landfill siteto be used as the cover soil.
(3) Requirements of setting up sediment yard and transportation:
The environmental impact of sediment stockpiling include: the odor to the atmospheric environement, the supernatant from the sediment yard supernatent to the surface water, to the landscape viewing. In order to reduce the negative impacts:
① Sediment yard should be set outside the urban area, away from residential area, at least 30m away, so as to reduce the influences of odor on the sensitive sites of the surroundings;
② The sediment yard should be set up near the dredging area of the river channel, laying out along the river channel, which can avoid the long distance transportation.
③ The yard should use bare land, avoiding to occupying farmland;
④ According to the design documents, a 25m buffer distance in Cihu river downstream is the land acquisition area of the project. After construction, the original landscapes should be restored and the sediment yard should be planted. The yard should be set up within the blueline of land acquisition to avoid the extra land occupation.
⑤It is suggested to set dam around the sediments yard and landscape greening after construction is finished, to avoid surface drying and dust in windy day, and to recover the vegetation and ecosystem.
Set ⑥ sedimentation tank, discharging supernatant in the sediment yard into Cihu river after sedimentation.
⑦ The transportation vehicle should select tankers to avoid scattered and reeking.
⑧ The transportation route should be carefullt selected to avoid residential area.
2. Construction Waste
The waste slag are mainly the construction waste from the demolition and reconstruction of the 5 pumping stations, where the estimated area of demolition is 1000 m2, the waste slag index from demolition area is 1350kg/m2, so the estimated construction waste is 1350t totally. The waste will be transported to the third construction waste disposal field, which located in the upstream basin of Cihu river, 12 km away from downstream.
3. Domestic Garbage in the Construction Area
It is predicated the domestic garbage produced during the construction is 531t. It must be collected on the construction site and transported out for disposal by the sanitation department. Properly treated, it will not have any obvious adverseimpacts on the environment.
7.1.5 Ecological Environment
1. Impact on Terrestrial Ecosystem
118
(1) Vegetation
Based on site survey of the occupied area of the project, there is no rare endangered plant under special protection at state level. The vegetation forms along the rivers are mainly farmland, wood land, which are the common species of the local area.
The project construction will affect the vegetation along the project, among which channel widening, temporary soil storage area and operation road will do the most serious damages. Though the project is with large construction work, everywhere it passes through is cultivated early, therefore the artificial disturbance rate is high, and most areas are covered by agricultural vegetation, which is scattered averagely.
The new permanently occupied land of the project will remove the surface vegetation in the area, which could not be restored during the period of operation. But the project will adopt ecological embankment, landscaping in the area of occupied land, which could compensate for the original vegetation coverage rate to some extent.
(2) Animals;
Based on survey, the project is surrounded mainly by residential area, farmland and industry area. The major animals along the river are common species and no rare and endangered animals are found.
During construction, the personnel are crowded and have frequent activities, which may result in escape of the animals to other places. Meanwhile, since the foods are becoming richer by the settlement of the workers, the mice in the surrounding areas will increase and the density will also increase. During the implementation, both sides of the river are ecologically greened, restoring the original vegetation to great extent, which is favorable for the survival and reproduction of birds and small mammals in the bush.
To sum up, the project construction will not cause serious impacts on the survival and reproduction of the plants and animals around and will not change the animal and plant communities within the assessed area.
2. Impact on Aquatic Ecosystem
The aim of dredging of the river channel is mainly to increase the sectional area of the canal for flooding discharge. Based on the actual situations of the river, the average dredging depth of the downstream of Cihu River is about 0.5m, and that of the branches is about 0.3m. Dredging of the river will destroy the living environment of the aquatic organism to great extent. A substantial part of the phytoplanktons will be removed and the survivals of the zooplanktons are threatened because of the destruction of their living environment, some even die. Most of the benthic species will be removed by the dredging of the sediments.
The phytoplanktons and zooplanktons in Cihu River and its branches are common species, which are mainly caused by the rich nutrition in the river and whose survival will threaten the
119
improvement of the water quality. Therefore, through dredging the river channel, the zooplankton and phytoplankton could be removed, which could effectively ensure the improvement of the water quality of the rivers.
3. Influences on the Scenery
The scenery types of the project evaluation area are farmland, forest land, rivers and unused land. In the process of construction, for the storage of materials and sediments, it is unavoidable to cause adverse impacts on the natural scenery along the river and destroy the harmony of the scenery; after construction, vegetation of the temporarily occupied land will be restored, among which the temporarily occupied farmland is restored to farmland, and the other lands are to be planted. Moreover, ecological embankment will be implemented along Cihu River and its branches, which could restore the original scenery to some extent and make the project in harmony with the surrounding terrain, landscapes and natural scenery.
4. Influence Analysis of Soil and Water Losses
According to Anhui the Twelfth Program of Water and Soil Conservation, the main erosion type in Anhui province is water erosion, with the water and soil loss area of 18,800km2, and the average erosion modulus in hilly areas is 1,700t (km2.a) and that in plain area is
700t （ km2.a ） . Based on the partition of water and soil conservation, Ma’anshan
Municipality is not included in the key prevention regions. It belongs to the type of Wanjiang plain area water and soil losses region, with the loss area of 81.2 km2.
This project mainly includes the widening and dredging of the river channel, the reinforcement of the embankment and the construction of the pump station. The construction may destroy the soil and the original soil vegetation, causing the destruction or reduction of the functions of the original soil and water conservation facilities. The original strengthening ability and resistance to erosion would be reduced, which may result in new soil and water losses. During the project construction, if effective comprehensive prevention measures are not taken, not only the progress of works would be affected but also the erosion of the soils in the project areas would be aggravated, which may result in soil and water losses. Therefore, strict environmental protection measures should be taken to control soil and water losses effectively:
(1) It is better to construct during dry seasons.
(2) With the aim of restoring the original surface productivity, topsoil stripping must be removed before the project construction. The stripping thickness is 0.3m.Conduct land recvlamation at the end of construction and refills the temporarily stockpiled topsoil with 30cm thickness for vegetation recovery.
(3)During construction, balance of earth work should be done well. The excavated earth is better to be used for flattening and refilling the construction site.
(4) It is suggested to set dam around the sediments yard and landscape greening after construction finished, to avoid surface drying and dust in windy day, and to recover the vegetation and ecosystem.
(5)The project construction should be carried out in stages. Mitigation measures should be taken for the exposed surface excavated, trying to minimize the exposing time and
120
reducing the soil and water losses.
7.1.6 Social Environment
1. Influences on the Traffic along the river
During construction, material transport vehicles will increase the traffic volume of the roads along the rivere, which is easy to cause traffic congestion and brings inconvenience to the passing vehicles; moreover, heavy vehicles may cause certain damages to the roads. Passing in and out of the construction vehicles and the occupation of the roads will inevitably cause traffic isolation, which will bring adverse influences to the residents along the river. Therefore, the contractors should strengthen management to minimize the influences on the local traffic along the river.
(1) The proposed construction should be constructed section by section so as to reduce the influences on the traffic in the travel areas of the residents.
(2) The construction machinery and routes of construction transportation vehicles should be under unified arrangement and related restriction rules should be issued to ensure the traffic of residents.
(3) The access road for transportation should be reinforced before construction, or shortcut should be built to connect with the original road. Repair severe damages to the road during construction immediately, or give the reparations to local highway management department for the repairing of the road.
2. Analysis of the Influences of the Land Occupation
This project doesn’t involve house demolition and relocation. The main impacts of are the acquisition of collectively-owned and national-owned land. The total land acquisition is 1788.89 mu. The land occupation will affect the residents’ life and the economic development. According to Measures for Land Expropriation Compensation and Resettlement in Ma’anshan Municipality, compensation will be made to the affected persons.
3. Analysis of the Influences on Cultural Relics
Based on the survey and the opinion from Ma’anshan culture committee, no ground relic is discovered in the construction area. Strengthening the propaganda in the process of construction to improve workers’ consciousness of cultural relics protection. Construction unit and supervision units shall stop working immediately when any cultural relics are found and shall report this to cultural departments promptly, then resume the work after geting the permit from cultural department.

The findings indicate that the residents think the influences brought by the project construction cannot last long so it can be accepted, and it is commonly acknowledged that the Cihu River environment and city scenery will be improved obviously when the project is finished. During the public consultation, local residents concerned the impacts on human health of the sediments usage on farmland and landscaping. The local residents do not agree with the option of utilization of sediments on farm and landscaping. And the risks to health and environment are low and the techniques are reliable of option of using the sediments as cover soil in landfill.in the public’s opinions. And the EA team and the design institute agreed to make detailed analysis of the impacts for the option that will use the sediments in
156
landfill as cover soil. This option has also agreed by the management of the Xiangshan Landfill.
The public opinion will be taken fully in the construction period, to implement environmental supervision and environmental monitoring, to ensure the reduction of environmental impacts.

Appendix
I.Methods of Evaluation
1. Single factor index
This method is mainly used to assess the present environment quality
（1）The formula of standard factor index:
In the formula: Pi--i is index of standard factors
Ci--I is index of density of standard factors, mg/L
Coi--i is standard of factor quality, mg/L
(2) The formula of pH value:
SpH,i=（7.0-pHi）/（7.0-pHsmin）（pHi≤7.0）SpH,i=（pHi-7.0）/（pHsminx-7.0）（pHi＞7.0）
In this formula: SpH,i-- i is standard PH index of monitoring sites
pHi --i is pH of tested water from monitoring sites
pHsmin --is the lower limit of standard index
pHsminx—is the upper limit of standard index

IV The analysis method of sediment
1、Monitoring pointsAccording to the survey, there were only three drainage outlets in the downstream of Cihu river. In order to know the sediment quality of Cihu river, 3 monitoring points were set up of the up, middle and down stream respectively(same as the surface water monitoring)2、Sampling methodThe sampling method was gained from the ‘Water and wastewaters monitoring and analysis method. The 0-50cm sediments was sampled and sealed into plastic sample box, then numbered and delivered to the libratory. 3、Analysis methodDehydrate the sediments with natural air drying way, divided into small samples with the coning and quatering method, and analyze the relative indicators, see detailed in table 11.Table 11 analysis method of sediment
