There are no circumstances under which it is legal to burn grass, hay, leaves, stumps or tires. They simply do not burn as "cleanly" as those materials that may legally be burned. All of them produce acrid smoke that causes nuisance conditions and threatens people's health. When tires are burned, they produce noxious gases and petroleum residue, both of which can be harmful to people and the environment. In addition, the burning of brush, cane, driftwood and forestry debris from commercial or industrial land clearing is prohibited statewide.
