173-425-040 WAC 173-425-040 Areas where certain types of outdoor burning are prohibited. (1) Nonattainment areas. Residential burning and land clearing burning may not be allowed in any areas of the state that exceed federal or state ambient air quality standards for pollutants emitted by outdoor burning. Theseareas are limited to all nonattainment areas and former nonattainment areas for carbon monoxide, particulate matter (PM-10 and PM2.5), sulfur dioxide, nitrogen dioxide, and lead. However, ecology may, incooperation with any local air authority having jurisdiction, authorize the omission of parts of a nonattainment area if ambient air quality standards for the pollutants that caused the area to be designated nonattainment have not been exceeded in those parts, and outdoor burning in those parts has not contributed, and is not expected to contribute, significantly to exceedances of the standards in the nonattainment area.

(b) The person responsible for the fire must contact the permitting agency and/or any other designated source for information on the burning conditions for each day. (c) The person responsible for an outdoor fire must extinguish the fire when an air pollution episode, impaired air quality condition, or fire danger burn ban that applies to the burning, is declared. In this regard: (i) Smoke visible from all types of outdoor burning, except land clearing burning, after a time period of three hours has elapsed from the time an air pollution episode, impaired air quality condition, or fire danger burn ban is declared, will constitute prima facie evidence of unlawful outdoor burning. (ii) Smoke visible from land clearing burning after a time period of eight hours has elapsed from thetime an air pollution episode, impaired air quality condition, or fire danger burn ban is declared, will constitute prima facie evidence of unlawful outdoor burning. (4) Unlawful outdoor burning: It is unlawful for any person to cause or allow outdoor burning that causes an emission of smoke or any other air contaminant that is detrimental to the health, safety, or welfare of any person, that causes damage to property or business, or that causes a nuisance. (RCW 70.94.040, 70.94.650(1), and 70.94.780) (a) Any person affected by outdoor burning may file a complaint with the permitting agency or other designated enforcing agency. (b) Any agency responding to an outdoor burning complaint should attempt to determine if the burning on any particular property is unlawful. This may include, but is not limited to, considering whether the burning has caused an emission of smoke or any other air contaminant in sufficient quantity to be unlawful. (c) Any person responsible for such unlawful outdoor burning must immediately extinguish the fire. (5) Burning in outdoor containers. Outdoor containers (such as burn barrels and other incinerators not regulated under WAC 173-400-070(1)) used for outdoor burning, must be constructed of concrete or masonry with a completely enclosed combustion chamber and equipped with a permanently attached spark arrester constructed of iron, heavy wire mesh, or other noncombustible material with openings not larger than one-half inch, and they may only be used in compliance with this chapter. (6) Other general requirements:(a) A person capable of extinguishing the fire must attend it at all times, and the fire must be extinguished before leaving it. (b) No fires are to be within fifty feet of structures.(c) Permission from a landowner, or owner’s designated representative, must be obtained before starting an outdoor fire.
