Program Overview
DEQ strives to provide residents every opportunity to burn without endangering public health. Open burning can have serious health effects if released to the atmosphere during times of poor ventilation.
Open Burning is allowed year-round, however, rules vary by season:
- During the spring and summer, open burning is regulated by counties.
- During the fall, DEQ issues county-wide restrictions based on the dispersion forecast.
- DEQ maintains a ventilation hotline and a map with restrictions during the fall.
- This information is linked in the dropdown menu below from September - November.
- 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.
- A request must be submitted via our online portal, which will be linked below during Winter Burn Season.
- Certain counties operate their own open burning programs. These counties must be contacted prior to burning.
- The list of these counties are located in the Outdoor Burning Forms & Contacts Section below.
- Prior to burning you must obtain a permit from your local county fire control authority.
- Most counties have burn permit applications available online at https://app.egovmt.com/burnpermit/.
- To activate your COUNTY burn permit, click on the link above on the day you would like to burn

Resources:
Agencies and companies that conduct prescribed burns on large amounts of land are considered Major Open Burners in Montana. Examples include federal and state agencies and large lumber companies.
Major burners typically treat over 5,000 acres of land every year with prescribed fire. More coordination with DEQ’s Air Quality Bureau is required to accomplish large-scale burning with minimal air quality impacts. These sources are regulated under the Administrative Rules of Montana (ARM), Chapter 17.8.6 – Open Burning.
Each year, the Air Quality Bureau issues a Major Open Burn Permit to those entities that meet the definition in ARM 17.8.601.
For Major Open Burn decisions and locations, visit the Montana/Idaho Airshed Group page.
