Environment Impact Assessment on power transmission project
Abstract: Environmental impact assessment as a legal system has made outstanding contributions to the country’s environmental protection. Studying on environmental impact assessment on power transmission project helps to avoid environmental problems brought by the development of China Power Grid. The object of EIA is the expansion of the 500kV Gulu transformer substation in Shanghai. Contents include: Environmental quality assessment; Prediction and assessment of environment impact; Environmental impact assessment of construction period. The main environmental factors of this project operation period include: environmental impact assessment on noise; environmental impact assessment on the surface water; environmental impact assessment on solid waste. According to the monitoring results of the sound environment of operation period, it can be concluded that the project of sound environment and wastewater meets the requirements of national laws. The main environmental factors of this project construction period include: noise; raise dust; wastewater and solid waste. There is no impact on the ecological environment. After researching field reconnaissance, collecting basic data and making preliminary analysis of construction, it can be concluded the related environmental sewage, dust and construction period of the project is in line with the national requirements.
Keywords: substation; environmental impact; environmental quality; noise; dust
