Basic Information about Air Quality FIPs
What is a FIP?
A Federal Implementation Plan (FIP) is an air quality plan developed by EPA under certain circumstances to help states or tribes attain and/or maintain the National Ambient Air Quality Standards (NAAQS) for criteria air pollutants and fulfill other requirements of the Clean Air Act.
EPA is required to develop a FIP if a state fails to submit a complete implementation plan, or if EPA disapproves a plan as not meeting Clean Air Act requirements. EPA may also develop a FIP for tribal lands if a tribe elects not to develop their own implementation plan, as appropriate.
