Energy and Coal Chemical Industry Base (ECCIB) is an important impetus of the development of regional economy, and it is also the guarantee of energy security of China. But, inevitably, the development of ECCIB causes the damage of the ecological environment, for the base is a collective place of many heavy industries. Environmental permit is considered to be one of the important source control measures. Implementing environmental permit in ECCIB has an extraordinary strategic significance for improving the quality of the regional environment and achieving sustainable development. The paper elaborates the concept and the connotation of environmental permit, and interprets the environmental permit of ECCIB from three aspects, namely policy level, environment level, and economic level. At last, the paper also gives some suggestions to its further development. All of these can help to promote the implementation of environmental permit of ECCIB in China.
