The federal Clean Air Act requires each state to maintain an inventory of air pollution emissions for facilities meeting specific criteria. The inventory is required to be updated every year. Each year, approximately 2,000 facilities report emissions. The emissions data is audited by EGLE staff and submitted to the United States Environmental Protection Agency (USEPA) for addition 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. Michigan's emission inventory is collected annually through MiEnviro Portal.
