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. 

See: Basic information about State Implementation Plans (SIPs) and Tribal Implementation Plans (TIPs)
