The Open Burning Rule is one of North Carolina's oldest air quality regulations, first adopted in 1971. The rule prohibits much outdoor burning and sets conditions for allowable fires. Under the rule, it is always illegal to burn trash and other non-vegetative materials. Leaves, branches and other plant growth can be burned under certain conditions. Violators can be fined up to $25,000 or more.
