Outdoor Air Quality
The Air Quality Program in Cascade County is under contract with the State of Montana Department of Environmental Quality. We continuously monitor the air for particulate matter (2.5 microns or less or PM 2.5). This site is located at Overlook Park on Tenth Avenue South.
The PM 2.5 information is displayed on the “TODAY’S AIR” link below for “real time” air quality (within 1 hour).
We conduct emission inspections for minor point sources within the County. These include gravel crushers, grain elevators, asphalt plants, crematoriums, etc.
Outdoor air quality concerns may also be directed to Environmental Health Services at 454-6950.
