A complete list of all programs within the Department of Environment, Great Lakes, and Energy (EGLE)
Community involvement and public participation are an essential part of EGLE’s mission, vision, and values.
SARA Title III establishes requirements regarding emergency planning and "Community Right-to-Know" reporting on hazardous and toxic chemicals for federal, state, local, and tribal governments, as well as regulated facilities.
Resources and information on utilizing RRD's data exchange and the Inventory of Facilities.
An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
The Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Water Well Viewer (WWV), is an interactive mapping system that displays water wells along with other information, such as wellhead protection areas, underground storage tanks, and sites of environmental contamination. Water well locations have been identified by address matching, the use of global positioning systems (GPS), and by legal descriptions.
This system allows water well drilling and pump installation contractors to submit water well records.
EGLE's interactive calendar is designed to provide timely information on decisions before the Director, proposed settlements of contested cases, administrative rules promulgation, public hearings, meetings and comment deadlines, and environmental conferences, workshops and training programs.
Anyone wishing to formally serve legal documents upon the Department of Environment, Great Lakes, and Energy (EGLE), or its officers or employees, may do so by the following methods.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) regulates levels of ground-level ozone in the outdoor air by making sure Michigan is meeting or “attaining” United States Environmental Protection Agency (USEPA) national ambient air quality standards.
Ozone is a regional pollutant that is formed in the atmosphere over time from emissions of Volatile Organic Compounds and Nitrogen Oxides. When these pollutants combine on warm, sunny days, harmful ground-level ozone may form.
When an area is not meeting the standard EGLE takes additional steps to bring that area back into attainment.
The West Michigan nonattainment area includes Berrien County and the western portions of Allegan and Muskegon counties. EGLE has opened five related documents for public comment the week of November 3, 2025.
These documents cover the West Michigan nonattainment area as a whole, and two specific portions: Berrien County and the western portion of Muskegon County. Information on the documents, their public comment periods, and how you can provide feedback are detailed below.

Reduce air pollution! Michigan and the USEPA have been working to lower ozone levels since 2018 and attain the standard in the West Michigan nonattainment areas (Allegan Partial-County, Berrien County, and Muskegon Partial-County).
The nonattainment areas can be redesignated as attainment once the standard is met and the required regulatory steps are taken.
If ozone concentrations remain above the standard, the nonattainment area would not be able to be designated as being in attainment.
West Michigan currently has areas designated as "Serious Nonattainment". This includes Berrien County and the western portions of Allegan and Muskegon counties.
Concentrations of ozone in the outdoor air helped determine when the area was not attaining the standard, as well as when the area was measuring concentrations below the standard.
Yes! Outdoor air concentrations of ozone in the Berrien County and Muskegon Partial-County nonattainment area for the 2015 ozone NAAQS have improved since being designated.
However, just measuring lower concentrations is not enough to redesignate an area into attainment. To do that, the state needs to show that the area has legally enforceable limits on how much NOx and VOCs can be emitted. Getting those enforceable limits in place takes time.
Nonattainment is a term applied to an area that has pollutant concentrations above federal air quality standards over a long period of time. An area may also be considered nonattainment if pollution from that area is contributing to poor air quality in another area. Areas that are meeting the air quality standards are considered attainment areas.
The USEPA and EGLE work together to determine whether an area is in attainment or nonattainment. If an area had air quality measurements of high ozone for three or more years, EGLE and USEPA staff review further data to determine if the area should be considered nonattainment. Nonattainment is based on a review of air quality measurements, emissions information, computer air modeling results which provide insight to the dispersion of air pollution, and weather patterns.
The USEPA’s Exceptional Event Rule states that an Exceptional Event can be caused by fireworks, prescribed fires, wildfires, high wind dust events, and stratospheric intrusions.
The USEPA revised the primary National Ambient Air Quality Standard (NAAQS) for ground-level ozone on October 26, 2015.
The new short-term standard was based on the 3-year average of the annual 4th highest daily maximum 8-hour ozone concentration. This level was set at 0.07 parts per million (ppm).
