The Department of Environmental Protection (DEP) requires permits for the installation or registration of industrial process and air pollution control equipment, including generators and equipment for mobile food vendors and gas stations. Air pollution control equipment users must also have a Certificate of Operation.

The Clean Air Tracking System (CATS) is DEP's online process for submitting an air pollution control application or registration.
