The burn ban prohibits the starting of outdoor fires statewide for purposes of brush and debris disposal, as well as uncontained campfires, and open fires used for cooking, according to the New York State Department of Environmental Conservation. Backyard fire pits and contained campfires less than three feet in height and four feet in length, width, or diameter are allowed, as are small, contained cooking fires. Burning garbage or leaves is prohibited year-round in New York state. Several municipalities also have burn bans in effect.
