Generally speaking, the classification and color separation point of Jiangyin enterprise sewage permit must be filled in. This is stipulated by the policy and needs to be observed.

"This system is a bit like' learning ability'. Enterprises disclose environmental protection information according to regulations, participate in learning and earn points. " The person in charge of the Emission Management Section of Jiangyin Ecological Environment Bureau said that the system ranks according to the accumulated points of enterprises every month, and the one with the highest points is listed as a trustworthy enterprise, which can enjoy the convenience of reducing the frequency of environmental law enforcement inspections, opening green service channels and giving priority to exempting large air traffic controllers. Similarly, low-scoring enterprises that are listed as untrustworthy in environmental protection will also be inspected.

In this system, the pollution discharge requirements of enterprises are divided into three modules: environmental protection law, self-examination and self-reporting, and social impact, and 33 specific behaviors. Enterprises can participate in learning, understand classic cases, learn environmental laws and regulations, implement pollution prevention measures, and feedback problems can be solved in time.
