Air Facility Systems Publications
The Air Facility System (AFS) contains compliance, enforcement and permit data for stationary sources of air pollution regulated by EPA, state and local air pollution agencies. Because this information is used by the environmental regulatory community to manage various programs regulated under the Clean Air Act, there are several publications issued relating to the database. This site provides links to the various collections of AFS publications. The Univeral Interface (UI) Publications page contains links specific to the UI. See also the AFS Web page.
