3 Project Background
3.1 Project Background
The ecological issues become more and more serious due to the wastewater distributed with high pollutant loads. With the larger scale sea development of the Bohai Sea, the contradictions between development and environmental protection become more seriously. Dongying City is the direct suffer from the serious pollution of the Bohai Sea. Only in 2008, the pollutant distributed by Dongying City to the Bohai Sea contains 2100t COD, 393t BOD, 368t NH3-N, 85t total phosphorus and 48t total nitrogen. Under this kind of status, WB and GEF conduct cooperation to improve the ecology system pollution of the large sea. In order to reduce the pollution to the Bohai Sea, Shandong Province utilizes the GEF grant and local counterpart fund to manage and control the pollution to the Guangli River of Dongying City which sets a good example for other river basin pollution management in Huai River basin.
Guangli River is the main drainage river of the central city in Dongying City, the river flows from Wangying Sluice of Nanzhan Dam of Yellow River to the central city with a flow path from west to southeast and then to the Bohai Sea after the combination with flood controlling rivers, the total length is 60km with a coverage area of 510 km2 which plays a important role in water supply, drainage, flood control and ecology improvement. Besides, Guangli River is the main wastewater catchment and nearly 40,000 ton/day of the wastewater was distributed to this river and its branches in 2009, more than 90% of that is urban daily life wastewater while the others is industrial wastewater. Due to the weak sewerage pipeline and the wastewater distributed to the river without treatment, the water of the Guangli River was seriously polluted. Though several improvement projects were conducted by Dongying City in recent years, the water quality of Guangli River still can not meet the Class V requirement.
In order to rehabilitate the ecology system, increase the biodiversity, prevent the water loss and soil erosion, improve the climate and conserve the water source and improve the water quality of Guangli River and Bohai Sea, Dongying City proposed to construct this project supported by WB.
3.2 Project Necessity

4.1 Contents of the Wetland Project
4.1.1 Land Acquisition Status of the Project
The total land acquisition area for the project is 2698.5 mus, including 73.5 mus and 2625 mus for west ecological retention pool and east surface flow wetland respectively. Only the fish ponds and saline-alkali fields are acquired within the land acquisition area, and these lands are under a low utilization rate with a low crops production. Since the project locates in the downstream of the river and the land acquisitions are in line with the national policies, so the current land status is good for the smoothly implementation of the wetland project.
4.1.2 Main Contents of the Project Construction
According to the regional hydrogeology, water quality, pollution sources distribution and land utilization status, and taking the development planning of Dongying City and the representativeness and promotion of wetland project into consideration, it is selected that the wetland project will be constructed at Dongba Road in the downstream of Guangli River.
（1）Process Scheme
The process of ecological retention pool + surface flow wet land is selected for the water purification project of Dongba Road Wetland. Through the construction of sluice gate in the north bank of Guangli River, the polluted water will be diverted to the bottomlands in the wets of Dongba Road and then the bottomlands will be transformed into ecological retention pool. The polluted waster will be discharged to the surface flow wetlands in the east of Dongba Road after the preliminary treatment in the retention pool. The pollutant of the wastewater will be reduced by the metabolic activities of microorganisms and aquatic plants existed in the retention pools and surface flow wetlands. The outflow will meet the Class V standard through the triple synergy of physical, chemical and biological roles of the wetlands. The outflow will be pumped into the water systems in Huanghe Road by the new constructed pump station once the outflow meets the required water quality standards. See Figure 4-3 for the detailed wastewater treatment process.

A comprehensive administration building will be constructed in the outlet of the wetland to manage the daily work and disseminate the wetland project to the public. The building has two floors with a construction coverage area of 480m2 and a parking lot was constructed with a coverage area of 300m2. A wooden platform was constructed in the wetland area for birds view with a width of 1.5m and a total length of 1500m.
4.1.3 Sluice Gate Operation Optimization
The pollutant discharging will be reduced through the sluice gate optimization; through the distribution, diversion, storage of the natural runoff, regulation of the water level and prevention of encroachment of sea water to ensure the management and utilization of the sluices.
Water Body of Guangli River
Before the water was discharged into the sea, the water will first flow into Dongba Road Wetland for treatment by No.1 Gate and then flow into the water systems at Huanghe Road by No.2 Gate, and then flow back to Guangli River.
Other Water Circulations
The hydraulic condition and water self purification ability will be improved by the periodically water supplement from the upstream (e.g. Wugan Channal) and water circulation measures. It will also contribute the continous operations of the downstream wetland.
During the flood period, the wastewater generated after the first flood should not be concentrative discharged so that can avoid the emergent water pollution for the river downstream and the entrance to the sea, and can reduce the pollution to the Bohai Sea.
With the regulation and self purification functions of Minghai Sluice Gate and Minghong Sluice Gate in Guangli River, Minghui Sluice Gate in Gengjing Reservoir, urban water systems and wetlands can avoid the wastewater concentrative discharging after the first flood and reduce the pollution to the Bohai Sea.
4.1.4 Public Utility Projects
①Water Supply
After the operation of the wetland project, the comprehensive administration building will in charge of the plant supplementing, diseases and pests prevention and control, plant harvest and transportation, plant selling, inflow and outflow quality and volume monitoring, inflow volume regulation and other administrative work. There are 5 administrative staffs in all. During the plant harvest time, the local peasants will be hired to harvest the plants, but the employment number depends on the plant volume. The water volume needed for one administrative staffs is about 80L/d, the water volume for operation period is about 0.4m3/d and the annual need water volume is 146m3, all the water needed is supplied by the municipal water supply pipeline networks.
②Drainage
The storm water and wastewater separation system is adopted for the drainage of the proposed project.
The storm water will be discharged to the nearest water body and the outlet was set up dispersively.
The septic tanks will be established in the waste outlet of the wetland administrative department and the waste will be collected and treated together and then transported by the vacuums of the sanitation department periodically.
③Heating
The wetland administrative department will use air conditioners for heating in winter.

（2）Crop lands Discharge Treatment(4 pilot villages)
The discharge of the crop lands refer to the runoff from the crop land after the irrigation or rainfall. Since the outflow is rich in nitrogen and phosphorous of the fertilizer utilized, so the runoff from the crop lands is easy to cause water pollution.
Pilot Villages Selection
The pilot villages are Shaotou Village in Xindian Street of Dongying District, Wangying Village, Shangzhuang Village and Huangdian Village in Shengtuo Town of Kenli County.
Controlling Measures of the Pilot Project
The designed discharge pollution treatment of croplands is buffer strips + eco-trenches.300 mus of crop lands were selected as the pilot crop lands nearby the drainage ditches and the buffer strips width is 10m.
The eco-trench system is made of construction and plant components. The cliff and bottom of the eco-trench are made of cellular concrete board and the cliff has a slope and small dams will be constructed in the trenches to lower down the water flow speed and increase the water retention time so that the nutrients will be precipitated and reduced.
Buffer strip refers to the lands with permanent plants to intercept the pollutant of the wastewater. The buffer strips are constructed along the lands nearby the drainage ditches, no fertilizer and pesticide used when planting the plants in the buffer strips, the plant can absorb the fertilizer and pesticides from the outflow from croplands.

Current implementation of artificial wetlands, detention pond and natural river channel for ecological repairing to the damaged river and water purification has been increasingly applied.
Construction wetland is the key of comprehensive control of a small valley " treatment, use and conservation", and is the last barrier purifying pollutants in the Valley. Success or failure of constructed wetland directly related to the ability to achieve the goal of river water quality.
Therefore, it is generally reasonable and practicable that combination ecological detention pond with surface flow constructed wetland as the process of wetland .
5.2 Alternaitve Analysis on Rural Sewage Treatment
Currently mainly rural domestic sewage treatment process includes applications, stabilization pond, artificial wetland, land processing technology, and so on.
Purification of domestic sewage digester is a decentralized domestic wastewater treatment equipment, it uses anaerobic digestion and aerobic biological filter combination approach, incorporating biological, chemical and physical processing together, uses the " multi-tage fermentation, a variety of multi-level aerobic filtration and purification" to achieve gradual removal of multiple pollutants in wastewater.
Septic tanks are a precipitation and anaerobic fermentation theory, suspension of organic matter removal in sewage treatment facilities, transitional living structures belonging to the primary.
Stabilization pond has a pond embankment and impermeable layer, its main use of aquatic biological systems, relying on natural biological purification of the sewage to be purified, is rapidly promoting wastewater treatment process, implementation of effective methods of sewage resource utilization and stabilization pond treatment technology in recent years.
Artificial wetland is the structure filling certain selected graded fillers at the bottom, such as gravel, sand, peat, and packing plant for sewage well in surface soil, high survival rate, longer growth period, beautiful aquatic plants, such as reed.
Land treatment system is a technology that put the sewage to the soil layers with a certain structure and good diffusion properties, using infiltration of soil capillary diffusion principle, energy flow through the cycle of matter in ecosystems and gradual degradation of pollutants, purification of sewage treatment systems.

Guangli River is the main drainage channels running through the center city of Dongying. It runs through Dongying District and Kenli County and is the only river connecting the Yellow River and the Bohai Sea. The River starts from Nanzhan Dam Wangying Gate of Yellow River, runs through the center city and converge with Yihong River into Bohai Sea by Guangli Port. It is about 60km, drainage area is 510 km2. It played an important role in the water supply, drainage, flood control and improving the ecological environment.
(2) Topography and geomorphology
The main physiognomy of Dongying is plain. The Yellow River flood punches the surface frequently historically, so it shapes the complex Subminiature Terrain. The ground falls away from the southwest to the northeast along the Yellow River. The maximum elevation of the southwest is 28 meters, compared with that the lowest elevation of the northeast is 1 meter. The natural ratio of reduced is 1/8000 ~ 1/12000. The maximum elevation of the west is 11 meters, the lowest elevation of the east is1m, the natural ratio of reduced is 1 / 7000. Yellow River passes through, and becomes "Ground river higher than its banks" respectively. The city has 5 types of micro-topography: the ancient flood heights, accounting for 4.15% total area of the city, mainly in the upper reaches of the Yellow River burst fan; flood heights, accounting for 3.58% of the total area of the city, mainly between the Yellow River to the levee; micro-inclined flat, accounting for 54.54% the total area of the city; the transition zone of depression; shallow depressions, accounted for 10.68% of the total area of the city.

The above table shows that the water quality of Guangli River is far exceeding the functional requirements of the "Surface Water Environment Quality Standard"(GB3838-2002) Ⅴ class standard.
(c) Undergroundwater
According to the routine monitoring data of Dongying City, the other of the monitoring projects except NH3-N and total coliform of groundwater monitoring points in evaluation area were able to achieve Class Ⅲ of "Water Quality Standards"(GB/T14848-93).
(d) Acoustic environment
The project area is mainly farmland and water, almost no noise source, only the natural noise. Acoustic environment quality is good.
(e) Ecological environment
① Status of vegetation: The wild vegetation along Guangli River mainly are herbaceous vegetation including reed grasses, huangxu vegetables, thatch, Sargassum, etc.. Herbaceous roots in many years are the main subjects, such as reed, Po son, reed grass in low-lying land, etc. Trees in the evaluation region were all planted, including locust, poplar, willow and other types of strong adaptability.
In short, the herbaceous plants are main species in the area. The plants species are common and general. There are no protected plants and rare plants in evaluation areas. Plant species are not diverse.
② Status of wild animals: According to the survey, birds include sparrows, magpies, mallard, gulls, etc; land animals have yellow weasel, hedgehog, mouse, rabbit, etc.; reptiles are snakes, lizards, geckos and so on.
2. The major environmental issues
A. A large number of untreated sewage spilled into the river directly
➢ Rain and sewage mixed emission in West City is serious.
➢ Sewage treatment plant construction is lagging behind.
➢ Supporting sewage pipeline is incomplete, construction quality but off.
➢ Part sewage wells are not installed trash grille, siltation is serious; part inspection well set up along interception trunk is blocked because poured a large number of construction waste and sediment in cross construction that leads to poor sewerage, sewage spills into the Channel.
➢ Pump station design is unreasonable along the river, facilities is inadequate
B. Non-point source pollution caused serious pollution of Guangli River water
➢ Fertilizer pollution
➢ Pesticide contamination
➢ Plastic sheeting pollution
➢ Stool contamination of livestock breeding industry
➢ Rural non-point source pollution. Water pollution control plan was not established during the comprehensive management of Guangli River. Heavy use of farm pesticides and fertilizers along river caused agricultural non-point source pollution and polluted water by farmland irrigation tail water and seepage field into Guangli River.
C. No external water caused the river water quality gradually deteriorate in dry season
Dongying is a less water city because of less precipitation and large evaporation. It relies on sewage into river to supplement water level in dry season because no fresh ecology water adds. There is only a small amount of irrigation tail water and seepage in the river and can not form a runoff after sewage into the urban sewage pipe network through the interception and guide sewage projects. Because intercepted by the River Gate, saprophytes are easy to breed in water and cause deterioration of water quality.
In view of the above problems, it is imminent to Implementation wetland engineering of Guangli River and control agricultural and rural non-point source pollution. Project implementation can effectively solve the issue.
6.4 The main environmental objectives
Project construction may have some effects on the surrounding villages and companies. The surrounding 1km within wetland has no village, but has 4 companies, the specific position and distance in Table 6-4. Agriculture and rural non-point source pollution control project designs several villages, and the construction process will take some impact, specifically in Table6-5.

7 Environmental Impact Assessment
7.1 Project Analysis
7.1.1 Processs flow
The construction of wetland includes sluice and pump station, ecological retention ponds, surface flow wetland and other match facilities.
The work content of wetland project and the agricultural and rural pollution control project include earth excavation, slope protection, construction of various infrastructures etc. The environmental impact of projects mainly is in the construction period, so EIA focuses on the construction period of the process.
1. Ordinary Processs flow
2. Processs flow of sluice
3. Processs flow of manual wetland
7.1.2 Analysis factors
(1)Construction period
①Atmospheric environmental factors
The main factor is dust generated in earth excavation, piling, transportation and fuel emissions generated by machinery.
The large wind is likely to produce more dust, increase suspended particulate matter in the air, bring some negative impact to the surrounding environment. General construction dust mainly affects on both sides of road within the scope of 60m.
Fuel machinery and transport vehicles in the construction process will exhaust wastegas, primarily NOx, THC and other atmospheric pollutants to affect on the surrounding environment.
Control Measures:
Equip with cleaning facilities; stamp with tarpaulin to transport vehicles; water regularly the Pile field; forbid the throw-type loading and unloading; apply the high quality fuelsto machinery and transport vehicles; add gas purification device to vehicles.
②water environmental factors
The main factors are sewage of workers, washwater of machinery and vehicles, concrete curing wastewater, pit drainage and so on.
Control Measures:
Install the simple toilets, sewage is collected and used as agricultural fertilizer, reuse the concrete curing wastewater precipitated by sedimentation tank, reuse the washwater of machinery and vehicles precipitated and separated by sedimentation tank.
③noise factors
The nosie generated by machinery and vehicles has an impact on the surrounding environment and interferes with people’s living and rest.
Construction machinery is the main noise source, noise sources in the construction zone flow pattern moving. Construction noise mainly occurs in the small piling, concrete mixing and the process of carrying earth, and noise level is about 70 ~ 105dB (A). The main noise equipments and the sound level can be seen in Table 7-1 as follows:
Table 7-1 the main noise equipments and the sound level
|No. |Name of equipments |sound level dB(A) |No. |Name of equipments |sound level dB(A) |
|1 |Excavator |79～83 |8 |chainsaw |90 |
|2 |Bulldozer |85 |9 |Welding machine |78 |
|3 |Loader |85 |10 |Flat shovel |80 |
|4 |lifter |72 |11 |Tractor |84 |
|5 |pump |70～80 |12 |pile |105 |
|6 |truck(3.5t) |79～83 |13 |Vibrating rod |105 |
|7 |crane |76 |14 |Concrete pump |85 |
Control Measures:
In construction process it should pay attention to reduce the man-made noise, take appropriate measures to reduce impact on environment, add sound insulation, rationalize the using-time of noise equipments, avoid construction at night, etc. At the same time, select the appropriate location for equipments; use the natural condition to minimize the noise impact.
④solid wastes factors
The solid wastes include roots, gravel, scrapped soil, useless materials, garbage, and so on.
Control Measures:
Roots, gravel, scrapped Soil, garbage (20t/a) are collected by the municipal sanitation department and transported to the local waste disposal sites; useless materials should be recycled by manufacturer.
⑤ Impact factors on ecological environment
Impact factors:
First, various types of plants within the occupied land will be eradicated, cut down, so that the vegetation has been permanently damaged.
Second,because of the excavation and cuting down the plants，bare land could easily lead to soil erosion by rain.
Third, all kinds of small animals such as voles and small reptiles are frightened and forced to move to another place or death by construction process.
Due to relatively short period of construction time, from the long and regional perspective, both the destruction of vegetation and the impact on the animals are smaller.
Control Measures:
For the inevitable ecological impact, it is necessary to develop the ecological compensation measures to make up the loss of a certain ecological impact, and develop temporary protective measures, land management measures, plants measures to make up the soil erosion.
⑥Impact on people
Infectious diseases are easy to spread in the onstruction site. As the living conditions of the site and the relatively poor sanitary conditions, labor-intensive workers, will lead to reduced capacity to resist disease, increase the risk of infection in long working hours.
Control Measures:
The saff need wear the necessary protective measures, such as gloves, masks, etc. Other, arrange reasonable working time for workers, and reserve essential drugs.
（2）Operation period
This project belongs to the river pollution control project, the pollution factor is few. During the operation relatively, emission are mainly sewage and garbage of workers.
① Wastewater
The five workers are responsible for replanting of plants, pest control, plant harvesting and removal, plant sales, and routine monitoring of the water quality of wetlands, water quantity management. The amount of sewage generated is 0.32m3/d (116.8m3/a), and the sanitation department is in charge of collection the sewage on a regular time.
②Gas
This project does not have air pollution sources, and relies on electric heating. So this project belongs to non-polluting project.
③ solid wastes
There is no other solid waste except the garbage of workers. The garbage (0.91t/a) is collected by the municipal sanitation department and transported to the local waste disposal sites.
④Impact factors on ecological environment
With the function of various wetland plants to gradually play, the ecological environment is recoveried. Expansion of the vegetation area impacts the local micro-climate and improves local ecological environment.
⑤After the project operates, effects on the ecological environment and landscape will be improved.
7.2 The generation and emission of pollutants and control Measures
As the environmental projects, the generation and emission of project pollutants and control measures can be seen in Table 7-2 as follows:

7.3 Environmental Impact Analysis
7.3.1 Environmental Impacts of wetlands during the construction period
7.3.1.1 Environmental Impacts on ecological environment
The structure and function of regional ecosystem will be re-adjusted to impact on the ecosystem.
After the wetland is constructed completely, the original project area aquatic and terrestrial ecosystems will gradually become wetland ecosystems. After the water quality is improved of the Guangli River, aquatic ecosystems which are seriously polluted now will change to the clean aquatic ecosystem, and it is good for ecological restoration.
（1）Environmental Impacts on biology
①Environmental Impacts on vegetation
Construction activities such as Excavation, stack etc will bring varying degrees of damage to regional vegetation, and even become secondary bare. The vegetation of other area does not be affected except Construction site.
These plants are widely distributed species, rather than rare species. Therefore, the impact of construction on the plant will lead only to reduction in the number, not the extinction of species. So the impact is local and will not bring the greater impacts to the regional ecosystem.
②Environmental Impacts on wild animals
Environmental Impacts on wild Animals during the construction period are:noise; part of the vegetation is destroyed; Construction will cut off the movement channels of certain animals, thereby affect the flow of the Species.However, due to strong migration of wild animals, those effects are temporary and partial,until the end of the construction will come to an end. The wild animals are the local common species (such as sparrows, magpies, rats, rabbits, snakes, etc), because of their migration and protection of animals, combined with the project covers an area is relatively small the impact on wildlife.
（2）Environmental Impacts on soil
Because of excavation within a certain area, the soil is disturbed and destroyed the original layer, even the arable layer. Excavation affects the soil fertility of the original topsoil, thereby affecting plant growth and yield. In addition, sewage, wash water, and solid waste may increase the load of soil pollution, as much as possible to handle them properly. There is not rare of soil organisms in this area, the destruction to the soil is temporary, so the ecological balance will soon be restored.
（3）Environmental Impacts on occupied land
The types of land occupied by the project mainly are wasteland and depression, and the construction of the project will change the types. according to preliminary plans, the project will cover permanently an area of 2698.5 acres. If a large number of spoil generated by excavation can be timely filled, used and minimized its exposure time, it can greatly reduce soil erosion. Almost all the excavated earth and stone can be backfilled.
（4）Impact on people
There is no village but 4 factories range 1km around the construction site. The types of impact on people are: blocking traffic, mechanical noise, dust, construction scene etc. It is necessary to take certain measures during the construction to control its impact within a certain range, thereby reducing the impact on the population. According to public participation, surrounding factories support for the project.
（5）impact of soil erosion
①The soil erosion mainly takes during the construction period, so we identify construction period as the forecast period. The total area of disturbance of the original landscape, damage to land and vegetation is 209.9hm2. Almost all the excavated earth and stone can be backfilled.
The project construction may make the soiland rocks stripped, vegetation damaged, soil erodibility added, soil fertility decline, even affect the ability of storage and flood control, so it has to take the positive control measures.
②Control measures:
⑴take the exposed surface around the wetland to be green; plant shrubs, grass etc to protect the road, plant low shrubs around the management office.
⑵Set the a temporary wall and drain around Spoil yard to avoid rain to wash out on the surrounding environment.
⑶It is necessary to take the appropriate measures to preserve stability of the embankment, and focus on drainage works.
⑷Engineering work should be tried to avoid scheduling during the rainy season or before the rainy season to reduce soil erosion in construction period.
（6）Impact on risk
If the pollutants of Guangli River are far beyond the purification capacity of wetlands, it could be led to large-scale pollution of wetland, weaken purification function, increase eutrophication, so it needs control the concentration of river.
（7）Impact on landscape
①landscape structure
After the completion of the project, landscape structure will change substantially, and most of the original landscape will disappeared. The area landscape will be changed from the reservoirs, saline, farmland into wetlands.
Combination of land using changes in the structure, the landscape structure of project area is made of retention ponds, manmade wetlands, slope and construction of structures.
②landscape function
Landscape is dominated by manmade wetlands. Purgative function of wetlands which play more action will gradually improve the environment, thus promoting local economic development.
（8）Control measures:
①construction should be srictly in accordance with design, reduce the amount of foundation excavation and the construction of the spoil. Stack the excavation better for site preparation.
②During the construction and installation, arrange the scope and route, do operations in accordance with regulations. Strict control and manage the scope of transport vehicles and heavy machinery, minimize damage to existing vegetation and soil.
③Forbid stacking materials randomly and designate the appropriate stack yard to prevent the expansion of the scope of plant damage.
④Should be excavated stratified according to the implementation of practice. Top soil should be stacked separately with the underlying soil; backfilling should also be layered as much as possible to maintain the original ecological environment. Accumulation should also leave enough appropriate level; prevent precipitation and runoff to lead to soil erosion and surface subsidence. The remaining soil should be tiled in the field, forbid not being thrown away.
⑤Do well the work of land reclamation, clean up the scene. Parts damaged by the vehicles and machinery must be repair and restore timely.
⑥After construction is completed, destruction of vegetation must timely restore.
（9）Invasion of exotic species
Wetland plants growing and around the slope greening in all process should pay attention to the invasion of exotic species. Once discovering of harmful exotic species, should take removing, inhibiting or control measures as soon as possible, to reduce the negative impacts. The control plans need to be developed, require the direct participation of ecologists, demonstrate fully the approach, and avoid causing more ecological damage. Also it needs to reach a consensus and support with local residents.
7.3.1.2 Ambient air impact analysis
The main factors are dust generated in earth excavation, piling, transportation and fuel emissions generated by machinery.
The amount of dust is relevant to many factors, such as construction site conditions, management level, degree of mechanization and the construction season, soil and weather, etc. General construction dust mainly affect on both sides of road construction within the scope of 50~200m. Spraying water is a good way to inhibit the dust, which cuts 80% of the dust.
Fuel machinery and transport vehicles in the construction process will exhaust wastegas, affect on the scope of 50m. The amount is smaller and open construction site is easy diffused for pollutants, so the dust impacts less on environment.
Because there is no village within the range of 200m around the construction site, Construction dust less impacts on surrounding villages.
7.3.1.3 Surface water environmental impact
The main factors are Sewage of workers, washwater of machinery and vehicles, concrete curing wastewater, pit drainage and so on.
Install the simple toilets, sewage is collected and used as agricultural fertilizer, reuse the concrete curing wastewater precipitated by sedimentation tank, reuse the washwater of machinery and vehicles precipitated and separated by sedimentation tank.
Therefore, the wastewater produced during construction has little effect on the surrounding environment.
7.3.1.4 Noise environmental impact
Machinery and vehicles will generate the noise, including: excavators, mixers, vibrating rods, concrete trucks, bulldozers, impact drill, air compressor, welding machine, etc.
Because there is no village within the range of 200m around the construction site, the noise less impact on surrounding villages.
7.3.1.5 Solid waste
The solid wastes include roots, gravel, scrapped Soil, useless materials, garbage and so on. Roots, gravel, scrapped Soil, garbage are collected by the municipal sanitation department and transported to the local waste disposal sites; useless materials should be recycled by Manufacturer.
The measure treated solid waste is reasonable and practicable, and it has little effect on the environment.
7.3.2 Environmental Impacts of wetlands during the operation period
7.3.2.1 Environmental Impacts on ecological environment
Once the project is completed, due to construction damage and affecting factors of soil erosion after the measures implemented gradually disappeared, reduced until it reaches a new stable state.
Through ecological greening project, operation period of significant reduction in the volume compared with the present situation of soil erosion, and soil erosion modulus becomes significantly smaller.
7.3.2.2 Ambient air impact analysis
This project does not have air pollution sources, and relies on electric heating. So this project belongs to non-polluting project.
7.3.2.3 Surface water environmental impact
Period of operation wastewater is mainly management’ sewage (0.32m3/d), and the sanitation department is in charge of collection the sewage on a regular time. Therefore, the project impacts less on Surface water environment.
The wetland projects after the completion, can effectively reduce point source and non-point source pollution load may reduce pollutants CODCr (430t/a) and of NH3-N (129 t/a) of the guangli River into the sea. Project construction will enable certain improvement in water quality in the Bohai Sea. At the same time, purified water returns to the huanghe Road water system, improves water quality, and reduces the water supply from the upstream water resources(e.g Wugan Channal).
7.3.2.4 Underground water environmental impact
The wetland projects don’t produce wastewater except Sewage. For regional geological conditions better, the wetland don’t lead infiltration to pollute groundwater. As long as strengthening the pipeline maintenance and necessary anti-seepage measures, the project does not have a larger impact on groundwater.
7.3.2.5 Solid waste
The solid waste is mainly garbage (0.91t/a) which is collected by the municipal sanitation department and transported to the local waste disposal sites.
In winter the wetland will harvest the plant s which are recycled and utilized by the around villagers. The sludge in wetland needs to be cleaned on a regular time. Because of belonging to a general solid waste, the sludge can be sent to the landfill and does not affect the normal operation of the landfill. So the project does not have a larger impact on environment.
7.3.2.6 Impact on landscape
The project changes the original appearance, increases the new landscape of wetland, selects the appropriate green way combining organically with the surrounding environment, and improves greatly water quality of the Guangli River.
In short, through the development and effective utilization of land, the project can change the environment of the city landscape, link engineering and environment, and improve the local landscape conditions. Therefore, the negative effects of projects on landscape environment are small.
7.3.2.7 Health protection of workers
The workers need wear the necessary protective measures, such as gloves, masks, etc.
It is necessary to set railings and other protective measures to prevent security vulnerabilities.
7.3.2.8 Relocation
There are 7 units in the area that wetlands cover.; Relocation would not have adverse effects on land because they are not involoved hazarouse production (e.g chemical). Relocation of the original 7 units will not cause greater impact on the surrounding environment.
7.3.3 Environmental Impacts of Agriculture and Rural Pollution Control Component
7.3.3.1 Positive impacts
The investments in Agricultural Pollution Control Sub-Component will have the following positive imapcts:
(a) Reduction of fertilizer pollution through use of alternative green/organic fertilizers, and precise application practices in the pilot villages. This includes use of alternative green fertilizers and precise application for winter wheat and corn crops, controlled precise fertilizer applications for paddy, balanced fertilizer application for cotton (based on soil fertility test results); as well as related training and technical assistance/extension services. It is expected that fertilizer use would be reduced by 15-20%, and utilization rate increase by 5-10%, leading to substantial nutrient loads (N, P) reducation to the Guangli River and significant cost-savings for the farmers。
(b) reduction of pollution for pesticide use through public awareness raising, training and technical assistance, channeled through FEPAs, for reduced use of pesticides and adoption of alternative green technologies such as moth-killing lamps (us of such lamps each covering for 3-4 ha area for demonstration purpose). These interventions are expected to reduce the pesticide use by 20% or more, resulting in both pollution reduction and cost savings;
(c) best practices for managing agricultural runoff (irrigation return flow and precipitation runoff from farm fields), to reduce nutrient and pollutant loads entering the Guangli river. Approaches include eco-trench, conservation buffer-strip, learning from international experiences. A farm area of 20 ha will be selected in each pilot village to apply the recommended technologies. The result expected is up to 90% of the pollutants from agricultural runoff removed in the target farm plots.
7.3.3.2 Negative effects

7.4 Social Impacts Analysis
7.4.1 Ecological and Landscaping Effectiveness
Various kinds of plants are planted in the wetland, such as bamboo reed, bulrush, cattail, lotus and hornwort, etc, willows, pseudo-cacias and other arbors were planted along the weirs and roads, then the stability of wetland system will be achieved which is mainly to reduce pollutants(e.g N,P) from the Guangli River. The ecological environment along the river banks and the outflow water quality discharged to Bohai Sea will be improved with the completion of the Dongba Road Wetland. The wetland system may become the habitat and food source for the waterfowls which plays an important role in biodiversity, ecological system stability and local climate regulation.
7.4.2 Social and Economic Benefits
After the completion of the wetland construction and rural pollution management, the river water quality will be improved and create a wetland landscaping which will improve the living environment quality of the residents. The proposed project plays an important role in water supply, flow volume regulation, flood control, embankment protection and toxic pollutant reduction, and the project contributes to the water quality of Bohai Sea. Besides, the wetland has the function for natural sightseeing, tourism and entertainment which can create a direct economic benefits. Meanwhile, the wetland has education, scientific research and cultural values and can increase the environmental protection awareness of the local residents and tourists.
7.4.3 Social environment impact analysis
7.4.3.1 Wetland
（1）Positive impact
First, Guangli River and the Yellow River Road system is a core component of the strategic planning of low-carbon eco-city of Dongying city. Projects to accelerate the efficient construction of ecological economic zone in the Yellow River Delta in Dongying city, has laid a good foundation. In 2010, urbanization rate of 58.5 in Dongying city, in a phase of rapid urbanization, high speed difficult to avoid the destruction of ecological environment in the development process. Project construction has a far-reaching significance to enhance the quality of urban development, urban development patterns, promoting sustainable development of cities,
Second, the construction project on the wetland system in Dongying city as a whole, have improved water quality, landscape and improve river flood control storage capacity effects. Project involves the Guangli River and the Yellow River Road. The watland connected Guangli River and the Yellow River Road water system, will promote the Dongying people's welfare.
Again, after the renovation of wetland landscape, itself is a public product. As a trunk River along the Guangli River of Dongying city, is a leisure place for local residents.
Finally, Dongying city close to the Bohai Sea, evaporation is greater than precipitation, scarcity of freshwater resources. Guanglihe runs through the urban area of Dongying, river water quality pollution eventually harmful Dongying people's drinking water health. By wetland construction regulation of ecological environment, can purify water, change this situation.
（2）negative effects
Wetland construction project involves several enterprise’s relocation during construction. Wetland construction project will occupy newly dug fish ponds and have an adverse impact on fisheries production. In 2010, many fish ponds started construction, some of them are forming. Project construction will make it difficult for fish pond owner's investment pays off.
7.4.3.2 Agriculture and rural pollution control projects
（1）Positive impact
In the harmonious development between human and environment concept under the guidance of the Government, has introduced a series of initiatives to improve the ecological environment in Dongying city. Rural sewage treatment is a low-carbon eco-city construction of Dongying one of the many initiatives. In 2009, municipal wastewater sewage treatment plant in Dongying city focused on rate of 75.8, away from the urban rural sewage treatment rates of almost 0. Rural sewage treatment project can improve rural sewage treatment capacity in Dongying city, helped to further enhance the city's sewage treatment capacity.
Guangli river in its upper and middle reaches has dual functions of both environmental and irrigation. Before the project construction, the live production sewage of DongJi town and shengtuo town discharge into guangli River untreated. Villagers use River water diversion irrigated farmland, forming secondary pollution of the soil. Construction of sewage treatment facilities can improve the capacity of rural sewage treatment, reduce sewage pollution of the water, thereby reducing the costs of pollution prevention, guarantee water health.
Now in Dongying Rural area sewage treatment is mainly through septic tanks. When the septic tank is full, dung is excavated, piling up along the street for a while, used as a farmyard manure. Livestock Farmers have a large amount of livestock manure, which are stockpiles without shetler. During wet season, faecal sewage infiltrates to groundwater, leading to disease. Especially those personnel and institutions such as schools, factories using groundwater as water source more likely suffers high incidence of diseases caused by sewage. Once the concentrated outbreaks of these diseases, it will seriously affect people's work and life, increase family additional medical costs.
Environmental protection associations committed to the promotion of environmental awareness of farmers, to make existing environmental protection facilities in rural areas in Dongying city, such as trash, played its best features. Environmental protection manual will guide the peasants under different soil and crops, targeted drugs, fertilizers, increased agricultural output, enhance revenue.
（2）negative effects
For construction and operation of sewage treatment facilitie in each counties, the biggest change to the local community means that the pipeline within families and communities pipes need to be laid and connected to sewage treatment facilties. Piping system of family and community incur cost. If it is fully borne by the masses, those families which is further away from the main sewer network hasve to bear more burdens, generating new social injustice.
For maintaining the normal operation of a wastewater treatment facility, owners need to charge a small sewage treatment fee, to achieve the guaranteed low - profit level sewage treatment plant. In 2009, Dongying peasants' annual per capita net income is $7326.91, and it is a low level in the eastern coastal cities in Shandong province. From families with lower incomes, increasing the sewage charge is not a small burden.
Agricultural non-point source pollution control avtivities located in farmland. The construction period, may result in damage to agricultural crops, reduce crop yields, thus reducing the farming peasants' income.

9 Conclusion and proposals
9.1 Conclusion
（1）Project Summary
The total investment for the proposed project is 0.2570678 billion RMB. The projects include: the wetland and sluice gate operation optimization; Implement the agricultural and rural pollutant reduction in the pilot villages along the Guangli River to reduce the pollution to the the Guangli River; Strengthen the capacity building, policy development and project management to increase the capacity of project management and PIU and achieve the sustainable development. After the completion of the proposed projects, the pollutant from the sources will be reduced effectively and the pollution to the surface water of Guangli River will be improved, the water sources will be protected, developed and utilized effectively and the pollution to the Bohai Sea will be reduced with a total CODCr of 430 t/a and total NH3-N of 129 t/a.
（2）environment quality
The environmental air quality can meet Ⅱ class of the "Environment Air Quality Standard "(GB3095-1996); water quality of Guangli River can not meet Class Ⅴof the "Surface Water Environmental Quality Standard"(GB3838-2002); Acoustic environment quality is good and can meet class Ⅱ of Environmental quality standard (GB3096-2008).
（3）Environmental impact analysis
①Ambient air impact
During construction period, it needs to take water to decrease dust.
During operation period the project has no air pollution sources, so less impact on ambient air.
②Surface water environmental impact
During construction period, sewage is collected and re-used, the concrete curing wastewater precipitated by sedimentation tank is reused.
During operation period, the sanitation department is in charge of collection the sewage on a regular time. Therefore, the project impacts less on Surface water environment.
③noise
In construction process it should pay attention to reduce the man-made noise, take appropriate measures, add sound insulation, rationalize the using-time of noise equipments, avoid construction at night, to reduce impact t on environment. Because there is no village within the range of 200m around the construction site, the noise less impacts on surrounding villages.
④Solid waste
Garbage is collected by the municipal sanitation department and transported to the local waste disposal sites, other solid waste should be recycled or effectively treated. So it has little effect on the environment.
⑤Impacts on ecological environment
The impact of construction on the animals and vegetation is temporary without adverse impacts on any endangered species. Afte the completion of the project, water quality improvement will contribute to a better eco-system.
The impacts on soil is temporary, and the ecological balance will soon be restored. With the function of various wetland plants to gradually play, the ecological environment is recoveried. Expansion of the vegetation area impacts the local micro-climate and improves local ecological environment.
To sum up, the project can purify Guangli River, reduce rural sewage pollution to guangli river, improve regional eco-environment, reduce the influence to the Bohai Sea impact. The project conforms to national industrial policy, the measures taken is reasonable and practicable, and does not have adverse effect on the environment of the region.
9.2 Measures and proposals
(1) Measures
①Strengthening management of the various materials in transportation and storage, especial cement. Into the construction site of cement to focus stacking, and covered canopy cloth, avoid windy make cement dust flying all over.
Various materials in the construction site need to focus stacking, and cover canopy cloth, avoid making dust in windy day. It needs to take water to decrease dust. The sanitation department is in charge of collection the sewage regularly.
②Construction should be srictly in accordance with design, reduce the amount of foundation excavation and the construction of the spoil. Stack the excavation better for site preparation.
③all vehicles shall be in accordance with the regulations on the road, avoid free to drive everywhere, destroy the vegetation in the region, easily lead to local wind erosion phenomenon.
④In strict accordance with the EIA specified control measures. When the project is completed, it must accept the department in charge of environmental protection.
（2）Recommendations
① Increase enforcement of environmental protection in the guangli River basin, strictly control illegal construction projects. Strictly implement of the environmental impact assessment and " three simultaneities " system.
② Increase agricultural non-point source pollution control, addressing use of chemical fertilizers, pesticides, of plastic sheeting in the agricultural production,while vigorously addressing rural sewage. Measures should be taken in the agricultural sector, guiding local farmers adjust planting industry, etc.
③ The wetland is a systematic project, and it must be combined with management measures. It must have long-term effective management, to project benefit into full play, so as to achieve the objective of this project. Relevant government departments need to do further detail of the investigation and analysis, so as to lay a solid foundation for the next project.
④ It Should be excavated stratified according to the implementation of practice. Top soil should be stacked separately with the underlying soil; backfilling should also be layered as much as possible to maintain the original ecological environment. Accumulation should also leave enough appropriate level; prevent precipitation and runoff to led to soil erosion and surface subsidence. The remaining soil should be tiled in the field, forbid not being thrown away.
⑤ The sewage shound be transported timely by the sanitation department, prohibit any emission, to avoid impact on surface water environment around.
⑥ Strengthening supervision, ensure construction of the relevant requirements have been implemented, avoid causing the local ecological damage and soil erosion without strict management.
