State Implementation Plan

Contact:  Air Quality Division 517-373-7023
Agency: Environmental Quality


The Michigan State Implementation Plan (SIP) contains the regulations and other materials for meeting clean air standards and associated federal Clean Air Act requirements. SIPs include:
1. State regulations that USEPA has approved
2. State-issued, USEPA-approved orders requiring pollution control at individual companies
3. In rare cases, federally promulgated regulations, designated as "FIP" (Federal Implementation Plan)
4. Planning documents such as area-specific compilations of emissions estimates and computer simulations (modeling analyses) demonstrating that the regulatory limits assure that the air will meet air quality standards.
