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 (NAAQSNAAQSNational Ambient Air Quality Standards are federal standards for the minimum ambient air quality needed to protect public health and welfare. They have been set for six criteria pollutants: sulfur dioxide (S02), particulates (PM/PM10), nitrogen oxides (NOX), carbon monoxide (CO), ozone (O3), volatile organic compounds (VOC), and lead (Pb).) for common air pollutants.
EPA is required to develop a FIP if a state fails to submit an implementation plan, or if the plan does not fully comply with the NAAQS. 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).
