Overview

Welcome to the Michigan Air Emissions Reporting System (MAERS) - Michigan's web-based application used in the collection of emission data from the permitted sources/facilities. The Michigan Department of Environmental Quality (DEQ), Air Quality Division (AQD) maintains MAERS reports for commercial, industrial, and governmental sources of air pollution in Michigan. The MAERS System offers new ways to report Emissions Inventory (EI) 24-hours a day, seven days a week - all from a single website.

The MAERS Internet Home Page serves as a clearinghouse for MAERS information. This site provides an overview of the AQD, Emissions Reporting Program, up-to-date MAERS news, information on where to go for help, as well as access to all the MAERS Forms, Instructions, and other guidance documents. You can access the MAERS Home Page at www.michigan.gov/deqair.
