It is strictly regulated.
Open burning in Missouri is permissible only under stringent conditions outlined by state and local authorities. The Missouri Department of Natural Resources (MDNR) enforces rules under the Missouri Air Conservation Law, while local fire departments and county ordinances may impose additional restrictions. Violations can result in fines up to $10,000 under the Clean Air Act, with enforcement by the Environmental Protection Agency (EPA) and MDNR. Recent 2026 compliance shifts emphasize stricter monitoring of particulate emissions, particularly in non-attainment areas like St. Louis and Kansas City.
