PROTECTING MICHIGAN'S AIR
EGLE ensures that Michigan's air remains clean by regulating sources of air pollutants to minimize adverse impact on human health and the environment. Goals are to meet and maintain air quality standards, limit emissions of hazardous and toxic pollutants, and inform the public about current air conditions.
COVID-19 UPDATE
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has closed its Central and District offices to help mitigate the spread of COVID-19. However, EGLE staff continue to work to provide essential services. The Air Quality Division has developed guidance to assist the regulated community in continuing to meet their air quality obligations and submit necessary information in a timely manner.

Air Quality Compliance
The Air Quality Division regulates complex industrial processes emitting air pollutants. With regulations for these industries being equally complex, having access to compliance assistance resources is important. This page contains links to all Air Quality Division programs as well as to a variety of resources designed to help the regulated community.

Michigan Air Emissions Reporting System: MAERS
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 collected annually using MAERS.
Each year, approximately 2,000 facilities report emissions to MAERS. Emissions data is submitted to the United States Environmental Protection Agency (USEPA) 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.

SIP & Attainment

State Implementation Plan (SIP) & Attainment
States are responsible for developing plans and implementing programs to meet and maintain National Ambient Air Quality Standards (NAAQS). Areas that meet the national ambient air quality standard are considered to be in "attainment" while areas in which air pollution levels persistently exceed ambient air quality standards may be designated "nonattainment." When NAAQS are tightened to better protect public health, some areas previously considered attainment may be designated to nonattainment even though monitoring shows that air quality continues to improve.
