   The Pollutant Discharge Permit system refers to an environmental management mechanism whereby environmental protection authorities issue legal permits to regulate and restrict pollutant discharge behaviors of entities through administrative approval processes. This system clarifies environmental management requirements and enables regulatory supervision based on permit provisions. Pollutant discharge entities specifically refer to enterprises, institutions, and other producers/operators listed in the Pollutant Permit Classification Management Catalog.

   The following entities shall be subject to pollutant discharge permit management:

  • Enterprises and institutions emitting industrial waste gas or nationally regulated toxic/hazardous air pollutants.
  • Coal-fired heat source operators of centralized heating facilities.
  • Enterprises and institutions directly/indirectly discharging industrial wastewater or medical sewage into water bodies.
  • Operators of urban or industrial centralized wastewater treatment facilities.
  • Other entities legally required to obtain pollutant discharge permits.

   The China Pollutant Discharge Permit Information Data released by CnOpenData comprehensively covers post-permit disclosure information, including Permit Information Disclosure Forms, Registration Information Disclosure Forms, Rectification Plan Forms with Deadlines, Permit Cancellation, Permit Revocation, Permit Loss records, etc. With rich fields and extensive data volume, this dataset provides robust support for environmental research.
