See figure 1 and figure 2. Liuzhou is one of the largest cities in Guangxi and is a major industrial city and a communication hub in Guangxi. In the past twenty years, Liuzhou has been experiencing rapid industrial and urban development. But, the urban environment is facing severe challenge. The most significant problems are acid rain and water pollution. In 2001, the industrial and domestic wastewater discharged by the city was about 800,000 m3/d. However, up to now only one Wastewater Treatment Plant is in operation whose capacity is 100,000 m3/d. Only 12.5% of urban wastewater is treated, far below the average level of the nation, which is 42.12% (data from Statistics Communique on Urban Construction of China in 2003, issued by the Ministry of Construction.). Since construction of wastewater treatment facilities is far behind the city's development, large quantity of wastewater was discharged into Liujiang River through drains and channels without any treatment. Consequently, water quality of Liujiang River (reach in Liuzhou city) has been deteriorated greatly. Furthermore, some municipal water plants now can hardly draw water from the original water intakes. They have to abandon these intakes and set up intakes on further upstream of the river (Liujiang river). The wastewater discharge problem has greatly degraded the citizens' living condition and held back the economic development. At the same time, the lower reach of Liujiang River is greatly polluted. Water pollution has now become one of the most significant environmental problems in Liuzhou city. Liuzhou Municipal Government attaches great importance to the water pollution of Liujiang River (reach in Liuzhou city) and urban water supply security. Liuzhou Urban Master Plan states, "Being a city near the river, Liuzhou Municipality should pay much more attention to the improvement and protection of water environment; improve the wastewater treatment system, and change the current situation that wastewater is discharged into the river directly. By 2010, the city's environment pollution and ecological deterioration shall be virtually under control. And up to 2020, the city's environment quality should be improved greatly and reach an appropriate ecological balance". Thereby, to implement Liuzhou Environment Management Project- Wastewater Treatment Component (hereinafter called Wastewater Component) is one of the key measures to reach the target of water pollution control in Liuzhou Urban Master Plan. Liuzhou Environment Management Project - The Wastewater Component includes Zhuexi Rehabilitation Project, Baisha WasteWater Treatment Project, Longquanshan WasteWater Treatment Project, Yanghe WasteWater Treatment Project and Labao WasteWater Treatment Project. The Wastewater Component is an important component under Liuzhou Environment Management Project. Liuzhou City Investment Construction Development Co. Ltd. (hereinafter called ICDC) has entrustsed Sino-Japan Friendship Center for Environment Protection to perform the environment impact assessment on the Wastewater Component on basis of "Environment Protection Law of the People's Republic of China", "Environment Impact Assessment Law of the People's Republic of China". "Environment Protection Management Regulations of Construction Projects", "Notification on Sino-Japan Friendship Center for Environmental Protection I  Liuzhou Environment Management Project - Wastewater Treatment Component Enhancing the management of Environment Impact Assessment of Projects financed by International Monetary Organizations", and relevant provisions in OP 4.01. According to the characteristics and nature of the Project, the assessment should meet the requirement of the World Bank for starting a new project, and comply with national environment impact assessment procedure and requirement. The enviroment assessment team prepared the Environment Impact Assessment report based on detailed project analysis, field survey, great deal of social, economic and environment information, environmental monitoring data, the Environment Impact Assessment Guildline and the WB pre-appraisal result. Now we submit the Report to the World Bank for appraisal and to the environmental protection authority for examination. Sino-Japan Friendship Center for Environmental Protection 2  Liuzhou Environment Management Project - Wastewater Treatment Component 1. General 1.1 Purposes of assessment The following are purposes of the environment impact assessment: (1) With information analysis, field survey, monitoring, modeling and analogical analysis, we made an overall assessment on environment, identifying the main existing problems. The assessment can help predict and assess the environmental impact of the project, and serve as the reference for the future examination when the project is completed. (2) With field survey and analogical analysis, we identified the environmental impact factors during the project construction and operation phases, and determined the parameters of major pollution sources. (3) With technical measures such as modeling and analogical study, we predicted and assessed the project's impact on ambient air, water, soil, ecological system, sound environment and social environment. (4) Based on the requirements of relevant laws and regulations, technical specifications, local natural and social environmental features, we proposed the protective measures for alleviating the environmental impact. (5) With the assessment of the Project, we provided information for the construction, operation, environment management and pollution control of the wastewater component; minimizing the negative impact of the project on ambient environment, maximizing the social-enviromental benefits. (6) The EIA deals with the water environment improvement in urban reach of Liujiang River, as well as the local water environment impact of effluent from wastewater treatment plants. We forcasted the environment impact under current hydrological condition as well as the future condition after the Honghua Hydro Dam is completed. The EIA is a comprehensive one involving not only the impact of this project, but also the impact of other existing and proposed projects. 1.2 References References are shown in table 1-2-1.

The classifiction is based on the Technical Guidelines for Environmental Impact Assessment (HJ/T2.1-2.3-93, HJ/T2.4-1995, HJ/T19-1997). ( 1 ) Water environment The impact on water environment of this project mainly occurs during the operation period when effluents discharge from Wastewater Treatment Plants whose discharge is about 20,000 t/d. The pollutant type number are >3. But less than 10 water quality parameters need to be prodicted. The wastewater is discharged into Liujiang River. Since Liujiang River is a major river, the water quality of Class III is required. In addition, the Honghua Hydro Dam will be built in lower reach of Liujiang River. Therefore, the environmental assessment on surface water in operation period is classified as Category I. (2) Sound environment The impact on sound environment is mainly from the noise from construction machineries during the construction period, and noise from equipments during the operation period. This noise during consrtruction is short-term. Since the plants are far from the densely populated residencial area, the sound environment assessment is classified as Category III. (3) Air environment The impact on ambient air of this project is mainly the dust pollution during construction period and the odor pollution during operation period. The pollution source are scattered sources with small amount of discharge, thus the ambient air assessment is classified as Category III. (4) Ecological environment On the basis of ecological system analysis, distribution of plants species, distribution of biogeocenose and the land utilization, there is no rare animal species. Moreover, this project is for pollution control. According to the assessment requirements in Technical Guidelines for Environmental Impact Assessment - non-pollutive Ecological Impact, the ecological environment assessment is classified as Category III. 1.3.2 Key point of assessment The implementation of this Project will be divided into construction period and operation period. The key points of assessment during the construction period are: * riverbed sediment Impact on the ecological environment; * measures for pollution control during construction; Sino-Japan Friendship Center for Environmental Protection 6  Liuzhou Environment Management Project - Wastewater Treatment Component Key points of assessment during the operation period are: * The project will improve the water quality in urban reach of Liujiang River but the effluent will pose impact on Liujiang River. The impact is a combined one. The assessment includes: a. Comprehensive impact on the water quality after the completion of the project; b. Impact of each componont on the water quality of Liujiang River during operation period. i impact of WWTP sludge disposal and measures for mitigating the impact. 1.4 Scope of assessment The scopes of assessment on water, air, sound and ecological environment of this Project are shown in table 1-4-1.
