Summary of the World Bank Loaned Project 2.1 Survev The World Bank loaned projects consist of six subprojects distributed in three cities in Shandong province. There are two projects in Jinan, one is the Jinan Yellow River Water Supply Pondage Reservoir project, the other is Jinan Waste Water Network project. The other two projects are Yantai 500 Heating Network project in Yantai city and Weihai No.3 CHP Plant in Weihai citv. The Xiaoqing River Revolving Funds Project and Yantai Demonstration Project of Cleaner Production are not included in the scope of assessment. 2.2 Brief Introduction of World Bank Loaned Projects 2.2.1 Jinan Yellow River Water Supply Pondage Reservoir Project The water is abstracted from Dawangmiao Sluice of Licheng District, through the pump station to sedimentation basin, then transported by deliverv pipeline to the reservoir.

Predicted Impacts on Environment and Mitigation Measures Taken 4.1 Jinan Yellow River Water Supply Pondage Reservoir Project 4.1.1 Predicted Impacts on Enviroiunent 4. 1. 1.1 Impacts on Environment in Construction Phase A. Impacts on Ecological Environment The project will be constructed in the Northern Stretch Embankment of Yellow River. The earth work will affect surrounding agri-ecological environment. B. Noise and Raise Dust Transportation, vehicle and machines will bring about noise and dust, which will affect the environment to certain extent. C. Migration 5  There are 1186 persons of 300 households need resettlement. The migration and land occupation will bring about certain impacts on living and industrial activities. 4.1 .1.2 Impacts on Environment after Operation The forecasting results of salinization and desertification of soil after operation show that after adopting the seepage prevention measure, digging penetration prevention ditches at the foot of reservoir's and sedimentation basin's dam, the secondary salinization can be avoided. After using of the sedimentation basins and sand stockvards, the secondary ploughing is an effective method to prevent desertification. The trend analysis of the reservoir's water quality show that'the water qualitv in Yellow River is in a stable state. The first water just after the Yellow River's drv-up is not suitable for abstraction. After analogical investigation and assessment of Pucheng Reservoir which has the same water source, geological and pollution sources conditions as the Queshan's, we know that after five-vear's operation of Pucheng Reservoir. its water is in middle eutrophic level, so we can draw the conclusion that there is no danger of eutrophication for Queshan Reservoir after its five-vear's operation. The control indexes for nitrogen and phosphorus are 0.6 and 0.04 mglI, respectively. 4.1.2 Mitigation Measures 4.1.2.1 Seepage Prevention Measures of Reservoir There is a soil film on the slope of box dam connected with another soil film vertically buried under the ground of dam base to prevent the seepage of the reservoir. 4.1.2.2 Around the box dam of the reservoir and sedimentation basin, the seepage prevention and drainage measures will be taken to prevent the soil's secondary salinization caused by the water level raise of groundwater. 4.1.2.3 Redesign and re-planning of discharging system of farmland in the project area. 4.1.2.4 Water Quality Assurance Measures If the water level of the reservoir is lower than 24 meter. the water 6  will not be suitable for abstraction. Water delivery pipes will all be buried under ground so as to reduce the impacts on surrounding environment and protect the water quality. 4.1.2.5 Secondary ploughing measure will be taken to prevent the sedimentation basins and sand stockvards from desertification after their lifetime. 4.2 Jinan Waste Water Network 4.2.1 Predicted Impacts on Environment 4.2.1.1 Impacts on Environment in Construction Phase Raise dust and noise in construction phase will have certain impacts on environment and transportation. 1,460 persons of 310 households will be resettled. 235.37 mu land will be occupied. The eighty three enterprises and one school will be affected. The total cost for migration and resettlement hits 64.7945 million yuan. 4.2.1.2 Impacts on Environment after Operation After operation, the water quality in service area of project will be improved and the pollution caused by wastewater's seepage will also be mitigated. The operation of wastewater treatment plant will improve the water quality of Xiaoqing River. 4.2.2 Mitigation Measures Advanced machines. rational arrangement of construction time, high construction efficiency, spraving water and covering of the soil will reduce the impacts of noise and raise dust to minimum level. 4.3 Yantai 500 Heating Network Project 4.3.1 Predicted Impacts on Environment 4.3.1.1 Impacts on Environment in Construction Phase * Raise dust and noise produced in construction phase will have certain impacts on surrounding environment. * There will be certain impacts on transportation. 7  * The total area of land occupation is 43.125 m2. No resident houses will be removed. Only 800 m2 house of village owned enterprise and 1,650 m2 building of Yantai Fuel Company will be demolished. 4.3.1.2 Impacts on Environment after Operation A. Newly Added Air Pollution Sources The newly added pollution source is the peak boiler. Its pollutants' emission volume and concentration can accord with the national standards. The maximum one-time concentration of S02 and TSP are only 10.6% and 0.83% of corresponding standards, respectively. B. Positive Effects 290 industrial boilers, 289 small boilers and domestic stoves will be replaced after operation of the CHP plant. It will save 132,100 tons coal for industrial use and 84,100 tons coal for domestic use annually. In winter, the emission amount of S02 and TSP will reduce 6,808 and 4,403 tons, respectively. The removal rates of S02 and TSP are 20.2% and 34.14%. The maximum removal rate of S02's and TSP's ground level concentration will be up to 60% and 40%. The guarantee rate of 20% of pollutants being removed is up to 60%. C. Noise Impacts on Environment Forty two pump stations are about to be constructed which will be have certain impacts on some region at night, but the noise level does not exceed the standard. 4.3.2 Mitigation Measures 4.3.2.1 Mitigation Measures in Construction Phase * The pipeline network should be buried under the land which does not have the natural resources. * Strengthen traffic management, the main traffic lines and commercial streets should not be selected as construction scope. * Advanced low noise machines should be selected and the construction should not affect the residents' rest. * Spraying water on the sands and soils at the two sides of roads to 8  reduce the raise dust. 4.3.2.2 Mitigation Measures after Operation A. Control Measure for Air Pollution The water film dust removal facilities with the removal rate of 980/o will be selected. The limestone will be added for desulfurization. (removal rate: 50%). The dust is emitted through a chimney of 80 meter. In coal yard, there is a water spraying instrument equipped. B. Control Measure for Noise Pollution Low noise machines and sound proof facilities are equipped. C. Control Measure for Ash and Cinder All the ashes and cinders are comprehensively utilized in brick factory. D. Control Measure for Water Pollution Wastewater will be discharged into wastewater treatment plant. 4.4 Weihai No. 3 CHP Plant Project 4.4.1 Predicted Impacts on Environment 4.4.1.1 Impacts on Environment in Construction Phase The impacts on environment in construction phase are from raise dust and noise. 4.4.1.2 Impacts on Environment After Operation A. Impacts on Atmosphere * Impacts on Atmosphere of Newlv Added Pollution Sources Under the stabilitv of B, C, D, the maximum landing concentration of S02 and floating dust can meet the corresponding national standards. In winter, the maximum dailv concentration of S02 is 0.0090 mg/m3, 9  accounting for 6% of the standard: the maximum daily concentration of floating dust is 0.0021 mg m3, accounting for 1.4
