Major Facility Review

Learn about the Air District’s Major Facility Review (Title V) Program, and the facilities subject to its requirements.

Major Facility Review Program

Created by Congress as an amendment to the Clean Air Act, Major Facility Review Program (Title V) requires large industrial facilities to issue a single comprehensive operating permit that shows all federal, state, and local air quality requirements. The program includes requirements to monitor emissions and make regular reports. See Air District Regulation 2, Rule 6.

Key features of the Major Facility Review process include:

  • Review of all federal, state, and local air quality requirements that apply to the facility.
  • A public notice and U.S. EPA review period. All comments must be addressed before the initial Title V permit is issued or renewed.
  • Federally enforceable requirements may also be enforced via citizen lawsuits.
  • The EPA can modify, terminate, or revoke and reissue a permit if necessary.
  • Permits must be renewed every five years with the full public notice and EPA review process.
