Open Burning

The St. Louis area has the most restrictive open burning regulations because of unhealthful levels of ground-level ozone pollution. In the St. Louis Ozone Non-attainment area, open burning is banned in the during the hot summer months. The by-products of open burning are hydrocarbons, which can form ozone (smog) in certain climatic conditions. Some hydrocarbons are also known carcinogens. A permit may not be necessary for the type and volume of open burning you plan, depending on the location. For information, permits, or complaints, call your local fire protection district or the MO Department of Natural Resources, St. Louis Regional Office at (314) 416-2960.
