Michigan's air monitoring network for 2024
Every year, the Michigan Department of Environment, Great Lakes, and Energy's (EGLE), Air Quality Division (AQD) does a review of the state’s air monitoring network to determine if any changes need to be made and to ensure adequate funding is available for monitoring activities planned for the upcoming year. In response to comments from the public, the AQD has extended the public comment period on the DRAFT 2024 Michigan Ambient Air Monitoring Network Review until June 30, 2023 and enhanced related information. The air monitoring webpage has been updated and additional resources have also been created and translated into Spanish and Arabic, including:
Michigan’s air monitoring network is made up of a series of locations throughout the state. These sites collect information about a variety of pollutants, such as ozone, carbon monoxide, nitrogen dioxide, lead and fine particulates that may be present in the ambient (outdoor) air. The monitoring network is a key element in making sure the air we breathe in Michigan is healthy.
Proposed changes to the monitoring network may be made based on historical data collected, changes to population levels, funding, as well as changes to the federal monitoring requirements under the Clean Air Act. This year, several changes are planned using American Rescue Plan dollars.

Proposed changes to the network for 2024:
- A new site around Northeast Detroit in the vicinity near GM Hamtramck and US Ecology-North to measure fine particulate matter (PM10 and PM2.5) and black carbon. It is anticipated to be functional in the fall of 2023 or spring of 2024.
- A new site with a continuous fine particulate (PM2.5) sampler in an enclosure at a location in Marquette, MI.
- New continuous fine particulate matter (PM2.5 ) samplers for the Oak Park, E. 7 Mile, Little River Band of Ottawa Indians tribal site in Manistee.
Sensors are becoming an important part of understanding and gaining information about air quality. You can learn more about sensors in this recent MiEnvironment article, For the citizen scientist, air sensors can be a tool to understand air quality conditions or visit US Environmental Protection Agency’s Air Sensor Toolbox.
The inventory of sensor technology is improved to include:
- Purple Air Sensors
- AirBeam2
- Portable weather stations
- Aeroqual Pro
- Aeroqual Starter
- Smoke kit
A strategy will be developed for deployment of these sensors in different areas around the state and in collaborative projects with local partner organizations and communities. Additional information is contained in the sensor section of 2024 Network Review.
How to comment:
Comments will be reviewed with respect to ambient air monitoring activities to be carried out in 2024. If you are interested in providing input on the review, comments will be accepted until 11:59 p.m. EDT on June 30, 2023.
