The definitions of terms contained in chapter 173-400 WAC are incorporated by reference. Unless a different meaning is clearly required by context, the following words and phrases as used in this chapter have the following meanings:
(1) "Adequate source of heat" means the ability to maintain seventy degrees Fahrenheit at a point three feet above the floor in all normally inhabited areas of a dwelling.
(2) "Area at risk for nonattainment" means an area where the three-year average of the annual ninety-eighth percentile of twenty-four hour PM-2.5 levels is greater than twenty-nine micrograms per cubic meter based on monitoring data for 2008-2010. Ecology processed all statewide data according to methods defined in 40 C.F.R. Part 50 Appendix N and determined that the following areas are areas at risk for nonattainment:
• Darrington;
• Marysville;
• Tacoma-Pierce County Nonattainment Area as described in 40 C.F.R. 81.348;
• Yakima.
(3) "Certified" means that a woodstove meets emission performance standards when tested by an accredited independent laboratory and labeled according to procedures specified by the EPA in "40 C.F.R. 60 Subpart AAA - Standards of Performance for Residential Wood Heaters" as amended through July 1, 1990.
(4) "Coal-only heater" means an enclosed, coal burning appliance capable of and intended for residential space heating, domestic water heating, or indoor cooking, which has all of the following characteristics:
(a) An opening for emptying ash which is located near the bottom or the side of the appliance;

(c) A grate or other similar device for shaking or disturbing the fuel bed or power driven mechanical stoker; and
(d) The model is listed by a nationally recognized safety testing laboratory for use of coal only, except for coal ignition purposes.
(5) "EPA" means United States Environmental Protection Agency.
(6) "Impaired air quality burn ban" means a condition where both of the following exist:
• Air quality has degraded or will soon degrade as described in WAC 173-433-140;
• Ecology or the local air authority restricts solid fuel burning device emissions to prevent air quality from worsening, or limit the time with poor air quality.
Ecology or the local air authority declares impaired air quality burn bans according to the criteria in WAC 173-433-140.
(7) "Jurisdictional health department" means a city, county, city-county, or district public health department.
(8) "Local air authority" means an air pollution control authority activated under chapter 70.94 RCW that has jurisdiction over the subject source.
(9) "Nonaffected pellet stove" means that a pellet stove has an air-to-fuel ratio equal to or greater than 35.0 when tested by an accredited laboratory in accordance with methods and procedures specified by the EPA in "40 C.F.R. 60 Appendix A, REFERENCE METHOD 28A - MEASUREMENT OF AIR TO FUEL RATIO AND MINIMUM ACHIEVABLE BURN RATES FOR WOOD-FIRED APPLIANCES" as amended through July 1, 1990.
(10) "Prohibit the use" or "prohibition" may include requiring disclosure of an uncertified device, removal of an uncertified device, or rendering an uncertified device inoperable.

(13) "Solid fuel burning device" (same as solid fuel heating device) means a device that burns wood, coal, or any other nongaseous or nonliquid fuels, and includes any device burning any solid fuel except those prohibited by WAC 173-433-120. This also includes devices used for aesthetic or space-heating purposes in a private residence or commercial establishment, which has a heat input less than one million British thermal units per hour.
(14) "Treated wood" means wood of any species that has been chemically impregnated, painted, or similarly modified to prevent weathering and deterioration.
(15) "Woodstove" (same as "wood heater") means an enclosed solid fuel burning device capable of and intended for residential space heating and domestic water heating that meets the following criteria contained in "40 C.F.R. 60 Subpart AAA - Standards of Performance for Residential Wood Heaters" as amended through July 1, 1990:
(a) An air-to-fuel ratio in the combustion chamber averaging less than 35.0, as determined by EPA Reference Method 28A;
(b) A useable firebox volume of less than twenty cubic feet;
(c) A minimum burn rate less than 5 kg/hr as determined by EPA Reference Method 28;
(d) A maximum weight of 800 kg, excluding fixtures and devices that are normally sold separately, such as flue pipe, chimney, and masonry components not integral to the appliance.
Any combination of parts, typically consisting of but not limited to: Doors, legs, flue pipe collars, brackets, bolts and other hardware, when manufactured for the purpose of being assembled, with or without additional owner supplied parts, into a woodstove, is considered a woodstove.
