Goal of environment management plan Purpose of environment management plan The construction implementation of this project will cause some environmental impacts on construction site. In the construction period, this project will have some adverse impacts on the atmospheric environment, the water environment, the sound environment and the ecological environment, while in the operation period, it will mainly benefit to the water environment and the ecological environment and improve the ability in prevention of flood and water logging. In order to explain in detail the contents of environmental impact elimination measures, environment management, environment supervision, environmental monitoring, and so on, the environment management plan has been formulated. It is a guideline document of the environment management in the project implementation process. Its function is as follows: (1) Make clear the goal of environmental protection and the measures of environment mitigation The project construction organization, the designing organization and the appraisal organization have investigated in detail on the panned land, confirmed the environmental protection goal, proposed the effective environment mitigation measures, and integrated them into the project design. (2) Be taken as the guidance document of environment management After the environmental monitoring plan is approved by the World Bank, it will be provided as the environmental protection text to the construction overseeing organizations, the environment surveillance organizations and other related organizations of this project construction period and the operation period. (3) To identify the responsibility and the functions of the related organizations The environment management plan has identified the responsibility and the function of the related functional departments and the management organizations and has proposed the channel and the way for communication exchange among each department’s. (4) Determine environmental monitoring plan during the construction period and the operation period The environmental monitoring plan in construction period and the operation period proposed in the environment management plan can guarantee the effective implementation of the environment mitigation measure and prompt processing of environment accident. Action guidelines and the requirements Under the efforts of the World Bank officials, the international consultation experts, the environmental impact appraisal organization, the Bengbu Environmental Protection Bureau and the project construction organization, the environment management goal of this project for construction period and the operation period has been determined as: maintains the coordinated development of social economy and environment in Bengbu City, improves the ecological environment in Bengbu City, reduces or mitigate the adverse effect on the project construction, minimizes environmental impacts. Specific actions: (1) To propose and implement the environment management and the environmental monitoring plan; (2) To propose and implement the pollutant control strategy to mitigate is adverse impact on the environment. Specific request: (1) To inspect the environmental monitoring standard determined in environmental monitoring plan during the construction period and the operation period; (2) To implement all the environment mitigation measures proposed in environmental impact assessment according to the stipulated procedure. 2. Establishment basis 2.1 Evaluation criteria 2.2.1 Environment quality standard (1) The atmospheric environment quality specification At present the ambient air quality appraisal carries out the corresponding standard according to Ambient air Quality Standard (GB3095-1996 + revision list in 2000).
