General Program Information

State Implementation Plan (SIP) and Attainment covers a wide range of functions related to air quality control, including:

  • SIP development
  • national and state policy development
  • development of rules and regulations to attain and maintain the National Ambient Air Quality Standards (NAAQS)
  • stationary source emissions summation, data calculation, and emission modeling
  • support for mobile source planning and NAAQS transportation conformity
  • technical evaluation and support for emissions trading programs

SIP Information

Michigan's SIP contains the regulations and other materials for meeting clean air standards and associated Federal Clean Air Act (FCAA) requirements. SIPs include:

  • State regulations that USEPA has approved
  • State-issued, USEPA-approved orders requiring pollution control at individual companies
  • 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
  • General Description of State Implementation Plan Types

In rare cases, federally promulgated regulations designated as Federal Implementation Plans (FIPs) are created in the place of SIPs. Although not actually SIPs, they are closely related.
