Open BurningĀ 

Program Overview

DEQ 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.

County Burning Contacts

Specific counties or impact zones have their own open burning programs and must be contacted directly to receive the proper air quality open burning permit prior to burning.  If burning will take place in one of these counties you must first contact the county before any burning takes place.

Western Burn Zone Dispersion Discussion and Forecast (Wednesday, Dec. 8):

High-pressure ridging combined with a strong jet stream aloft and a short wave disturbance propagating through at mid-levels makes for a breezy day at the surface Wednesday, and overall excellent burn zone ventilation for this time of year. Precipitation and icing are likely in the northwest half of the burn zone during the early hours of Wednesday morning. High wind warnings have been issued for Glacier County and the Rocky Mountain Front through Wednesday evening. By mid-day Wednesday, an inflection point in the jet stream passes over, marking the transition between ridging and the next cold front trough. Thursday and Friday are expected to be cooler and dominated by a fairly dry trough coming down from Canada. Thursday the upper-level pressure gradient relaxes and winds are expected to let-up compared to Wednesday. Ventilation will still achieve marginal to good ranges in most locations due to the passing of a short wave trough. Cooler, unstable air Wednesday afternoon through Friday is likely to generate accumulating snow in the mountains and along mountain passes. The active weather pattern is expected to continue as western Montana will begin to feel the effects of a heavily moisture-laden Pacific trough Sunday that is expected to dominate burn zone weather for the first part of next week.

Information regarding DNRC fire safety restrictions is included on the map above. Further information can be found at this DNRC link. Keep track of hourly particulate concentrations at todaysair.mt.gov and please burn safely!

March through August Open Burning Instructions:

How To Burn:
  1. Obtain a permit from your local county fire control authority (many counties can be found here).

  2. On the day of your burn, activate your county permit here.

  3. Be aware of local conditions and burn smart.

  4. Check back here on September 1 for fall burning restrictions.

Fall Burning Instructions - September 1 through November 30

During the fall season, burning is regulated by county in the western burn zone. Each day, county restrictions are posted on the Burn Restrictions map  and on the ventilation hotline 800-225-6779.

Prior to burning you must obtain a permit from your local county fire control authority.

After you have obtained a county burn permit:

  1. Ensure that there are no burning restrictions due to fire safety concerns.
    • Montana fire restrictions are posted on this Montana DNRC map.
    • Check with your county government for local burning restrictions.
  2. Determine if you are in the western or eastern burn zone.
    1. If you are in the western burn zone:
      1. Check the Burn Restriction map or call the Ventilation Hotline at 800-225-6779 for any air quality restrictions the day of the burn.
      2. If there are no restrictions for either fire danger or air quality be aware of local conditions and burn smart.
    2. If you are in the eastern burn zone, be aware of local conditions and burn smart.

Please call 406-444-3490 if you have any questions.

    • If your burn application is approved, the email will include a Burner Identification Number (Burner ID).
  • Confirm that your burn location is correct by searching for your Burner ID in the Burn Requests & Restrictions Map above.
    • If your burn is not shown in the correct location, please email DEQMTSmoke@mt.gov or call 406-444-0283.
One or two days before you wish to burn:
The morning you wish to burn:

    • Burn Identification Number (Burner ID) 
    • Number of piles you would like to burn that day
    • Number of hours you plan to burn.
  • The meteorologist will either approve, approve with specified conditions, or deny your request.
    • Once a decision has been made, the requested burn will appear on the Burn Restriction and Request Map.

After you have completed all burns for the winter season:
  • Please email DEQMTSmoke@mt.gov or call 406-444-0283 to remove your Burner ID from the website.

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.
