Air Quality and Ventilation

Flathead County Environmental Health monitors outdoor air quality, administers the Flathead County Air Pollution Control Program, and provides resources related to ventilation, open burning, air quality complaints, radon, asthma, and local air quality regulations.

Outdoor Air Quality Program

Flathead County Environmental Health collects outdoor air quality data from monitoring sites in Kalispell, Whitefish, and Columbia Falls and administers the Flathead County Air Pollution Control Program.

The program uses air monitoring data, ventilation forecasts, and local air quality regulations to help protect public health and reduce air pollution impacts in Flathead County.

Open Burning and Daily Ventilation Decisions

Flathead County uses air monitoring data and ventilation forecasts to help determine when open burning is allowed. Daily burn decisions may consider mixing height, ventilation rate, wind speed, pressure, and current air quality conditions.

For permit instructions, daily activation, and burn restriction resources, visit the Flathead County Burn Permit page.

To find out if open burning is allowed today, call 1-866-207-2577.
