Streamlining the SIP Process
EPA's goal is to minimize federal and state burden in developing SIPs, but ensure the plans' effectiveness in complying with the Clean Air Act. Through collaboration with the The National Association of Clean Air Agencies (NACAA/ECOs) SIP Reform Work Group, EPA has issued the following guidance memos to aid states in the SIP development process.
