The EMP is a separate document involving all activities for environment protection during phases of design, construction and operation. The EMP offers a guideline for pollution control, environment management and environmental monitoring. The EMP consists of: * Introduction * Potential environmental impact * Management structure and duty * Environment management plan * Environmental monitoring plan Purpose of EMP: Well-balanced design and serious environment assessment have been made for the "Wastewater treatment component, Liuzhou Environment Management Project (LZEMP)" in order to minimize the adverse impact onto society and environment. Appropriate environment protection policies will be followed to solve the environment problems. It is inevitable that the project will pose impact onto environment. One of the primary purposes of EMP is to identify potential impact so as to develop technically and economically feasible policies for environment protection in construction and operation phases. The policies were determined in environment assessment phase, are confirmed in EMP, and will be carried out in construction and operation phases. The EMP includes the policies for environment protection during construction and operation, environmental monitoring measures and detailed activities to avoid or reduce the adverse impact onto environment. The EMP will be an important intermediate between environment protection policies and actual activities, which ensures the realization of environment protection objective.

Introduction 1.1 Significance of component Liuzhou is a major industrialized city and a traffic hub in Guangxi. In recent 20 years, with the rapid industrialization and urbanization of Liuzhou, the environment has been seriously threatened by pollution, especially acid rain and water pollution. In 2001, the total discharge of industrial and domestic wastewater was 800 thousand m3/d. Today, only one wastewater treatment plant with 100 thousand m3/d capacity is in operation, which is able to treat merely 12.5% of the total discharge, much less than the average level (42.12%) of wastewater treatment percentage in China (data from "China Urban Construction Statistics 2003" issued by State Ministry of Construction). Because the Liuzhou's domestic wastewater treatment facilities are much inadequate, large amount of untreated wastewater is discharged via Xigou Stream and other drains into Liujiang River, producing significant pollution onto Liujiang (reach in urban area). As a result, some pilot intake become unsuitable for water service, and source water have to be piloted far upstream Liujiang River. The water problem has significantly degraded citizen's welfare and held back economic development. Water pollution is the most serious environment problem in Liuzhou. Liuzhou municipal government has seriously recognized the significance of water pollution problem and water supply security. "Liuzhou master urban planning" points out, "Being a riverside city, Liuzhou should emphasize greatly on the water pollution control and water environment protection. Well-established municipal wastewater treatment system should be set up to reduce direct wastewater discharge into river as soon as possible. By 2010, the urban environment pollution and ecological destroy should be substantially controlled. By 2020, the urban environment quality should be greatly improved and a well-balanced ecological system should be established. Therefore, it is very important to implement the Wastewater Treatment Component, Liuzhou Environment Management Project (LZEMP) so as to achieve the water pollution control objective in "Liuzhou master urban planning". 1.2 Component description and technical data Wastewater Treatment Component, Liuzhou Environment Management Project (LZEMP) consists of five parts, including river rectification, ecological recovery, wastewater collection and wastewater treatment etc. The Component will use land of 621.29 mu, improve river course of 10.8 km long, set up and rebuild drain pipes of 131.98 km long, establish 7 wastewater pump stations (total capacity 264 thousand m3/d), construct and reconstruct 4 wastewater treatment plants (addition of 400 thousand m3/d capacity). The construction location and specific data are shown in Figure 1-1 and Table 1-2-1.
