The Federal Clean Air Act requires that each state maintain an inventory of air pollution emissions for certain facilities and update this inventory every year.  Michigan's emission inventory is the Michigan Air Emissions Reporting System (MAERS).  The Michigan Department of Environmental Quality, Air Quality Division (AQD) maintains MAERS reports for commercial, industrial and governmental sources of air pollution in Michigan.  Emissions data is submitted to the United States Environmental Protection Agency (U.S. EPA) to be added to the national data bank.  This information is used to track air pollution trends, determine the effectiveness of current air pollution control programs, serve as a basis for future year projections of air quality, track source compliance, provide information for permit review and calculate the emissions portion of the air quality fee.

MAERS reports are due by March 15 each year.  The AQD is required to notify each facility at least 45 days prior to the deadline for submitting the report.
