What your town can add in Montana
Counties set the fire safety side of the rules, and seven county or city county health and air pollution programs run their own open burning permits that a resident must go through instead of the statewide system.
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.Open Burning, Montana Department of Environmental Quality, read September 23, 2026.
