Current through Register Vol. 24-14, July 15, 2024
506.1 PURPOSE.
This Section establishes emission standards, certification
				standards and procedures, curtailment rules, and fuel restrictions for solid
				fuel burning devices in order to maintain compliance with the National Ambient
				Air Quality Standards (NAAQS) for fine particulates and to further the policy
				of the NWCAA as stated in Section 102 of this Regulation.
506.2 DEFINITIONS.
Unless a different meaning is clearly required by context,
				words and phrases used in this Section shall have the following meaning as
				defined in Chapter 173-433-030 WAC:
ADEQUATE SOURCE OF HEAT
- means a
				permanently installed furnace or heating system, connected or disconnected from
				its energy source, designed to maintain seventy degrees Fahrenheit at a point
				three feet above the floor in all normally inhabited areas of a residence or
				commercial establishment.
ANTIQUE WOOD STOVE
- is a stove
				manufactured before 1940 which has a current market value substantially greater
				than a common wood stove manufactured during the same time period.
CERTIFIED
- means a solid fuel-burning
				device that meets emission performance standards when tested by an accredited
				independent laboratory and labeled according to procedures specified by EPA in
				the Code of Federal Regulation - Title 40 Part 60 Subpart AAA - Standards of
				Performance for Residential Wood Heaters as amended through July 1, 1990; or a
				solid fuel-burning device that has been determined by Ecology to meet emission
				performance standards, pursuant to RCW  70.94.457.
COOKSTOVE
- means a wood-fired
				appliance designed primarily for cooking food and containing an integrally
				built in oven, with an internal temperature indicator and oven rack, around
				which the fire is vented, as well as a shaker grate, ash pan and an ash
				clean-out below the firebox. Any device with a fan or heat channels used to
				dissipate heat into the room shall not be considered a cookstove.
ECOLOGY
- means the Washington State
				Department of Ecology.
EPA
- means the United States
				Environmental Protection Agency.
SEASONED WOOD
- means wood of any
				species that has been sufficiently dried so as to contain twenty percent or
				less moisture by weight.
SOLID FUEL BURNING DEVICE
- means a
				device that burns wood, coal, or any other non-gaseous or non-liquid fuels, and
				includes wood stoves or 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 have a heat input of less than one million British thermal units per
				hour.
SUBSTANTIALLY REMODELED
- means any
				alteration or restoration of a building exceeding sixty percent of the
				appraised value of such building within a twelve-month period.
TREATED WOOD
- means wood of any
				species that has been chemically impregnated, painted, or similarly modified to
				improve resistance to insects, weathering or deterioration.
WOOD STOVE
- means a wood-fueled
				appliance, other than a cookstove, capable of and intended for residential
				space heating and domestic water heating that meets the criteria contained in
				"    40 CFR 60     Subpart AAA - Standards of Performance for Residential Wood
				Heaters". 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 wood stove, is considered a wood stove.
506.3 EMISSION PERFORMANCE
			 STANDARDS.
(A) Solid Fuel Burning Devices - A
			 person shall not advertise to sell, offer to sell, sell, bargain, exchange, or
			 give away any solid fuel burning device in Washington unless it has been
			 certified and labeled in accordance with procedures and criteria specified in
			 "  40 CFR 60   Subpart AAA - Standards of Performance for Residential Wood
			 Heaters", complies with WAC 173-433-100, and meets the following particulate
			 air contaminant emission standards:
(1) Two
			 and one-half grams per hour for catalytic wood stoves; and
(2) Four and one-half grams per hour for all
			 other solid fuel burning devices.
