Michigan's air monitoring network for 2025 open for public input
The Michigan Department of Environment, Great Lakes, and Energy has released the DRAFT 2025 Michigan Ambient Air Monitoring Network Review for the public to provide input on until June 15, 2024. Every year, the 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.
Michigan’s air monitoring network is made up of over 45 locations throughout the state with over 100 air monitors. 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.
Proposed changes to the network for 2025:
- A new site around Northeast Detroit to measure fine particulate matter (PM10 and PM2.5), black carbon, and air toxics. It is anticipated in fall 2024 or early 2025.
- A new site to measure PM2.5 and air toxics in East Detroit. It is anticipated to in fall 2025.
- Discontinue every 3-day filter based PM2.5 sampler in Southwest Detroit since a continuous sampler is being operated at that location.
- Discontinue every 6-day filter based PM10 sampler at the Southwest Detroit location since PM10 is being measured at other nearby locations.
- Reduce the frequency of lead measurements at the Belding site since the industrial facility of concern closed in 2023.
- Special sampling for volatile organic compounds for 6-months in Kalamazoo and Flint.
- Enhanced ozone monitoring parameters at the Holland site to evaluate ozone moderate non-attainment.
