Open BurningĀ 

Program Overview

The Montana Department of Environmental Quality strives to provide residents every opportunity to burn without endangering public health.

Open burning is regulated because smoke from open burning can have serious health effects if released to the atmosphere during times of poor ventilation. 

Open Burning is allowed year-round, however, requirements to obtain a dispersion forecast prior to burning vary by season.

  • During the Spring and Summer no DEQ dispersion forecast is needed.
  • During the Fall DEQ issues county-wide restrictions based on the dispersion forecast.
  • During the Winter opportunities to burn based on dispersion forecasts are granted on a case-by-case basis.
    • DEQ reviews the atmospheric conditions daily across the state and determines where it is safe to burn from an air quality perspective and where burning may cause health impacts.
  • Certain counties operate their own open burning programs. These counties must be contacted prior to burning.

For more information see the “Why Can’t I Burn” brochure.

Forecast (valid Sep 16):

It’s been a windy day today (Wednesday), and strong westerly winds are expected to continue through the afternoon. A cold front will sweep southeast across the region this afternoon, as a weak trough pushes our way and turns the winds more northwesterly. Temperatures cool a bit for Thursday and expect breezy conditions again. The northwest flow should offer a little wildfire smoke relief to Montana, however fires are still active to our west, so intermittent GOOD to MODERATE particulate levels likely will persist. A significant trough is on track to reach the Pacific coast on Friday, which turns the flow southwest and warms temperatures a little for Friday and Saturday. As the trough makes its way over the state, cooler and wetter weather is expected on Sunday and into next week.

Remember to look for local fire restrictions, which can be found on this DNRC map. Keep track of hourly particulate concentrations at todaysair.mt.gov and burn safely!
