Guidance on Streamlining the SIP Process

This page contains guidance memos to aid states in developing air quality State Implementation Plans (SIPs). The goal of this guidance is to minimize federal and state burden in developing SIPs, while still ensuring the plans' effectiveness in complying with the Clean Air Act. It was developed through collaboration with the National Association of Clean Air Agencies (NACAA/ECOs) SIP Reform Work Group.
