Air Quality and Ventilation

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.
