     (2) An increase or decrease in actual emissions is contemporaneous with the increase from the particular change only if it occurs before the date that the increase from the particular change occurs.

     (3) An increase or decrease in actual emissions is creditable only if:

     (i) It occurred no more than one year prior to the date of submittal of a complete notice of construction application for the particular change, or it has been documented by an emission reduction credit (ERC).

     (2) An increase or decrease in actual emissions is contemporaneous with the increase from the particular change only if it occurs within five years before the date that the increase from the particular change occurs.

     (3) An increase or decrease in actual emissions is creditable only if ecology or EPA has not relied on it in issuing a PSD permit for the stationary source, which permit is in effect when the increase in actual emissions from the particular change occurs.

     (4) An increase or decrease in actual emissions of sulfur dioxide, particulate matter, or nitrogen oxides, which occurs before the applicable minor source baseline date is creditable only if it is required to be considered in calculating the amount of maximum allowable increases remaining available.

AMENDED SECTION

RULE 8.1 ((RESIDENTIAL)) WOOD HEATING


     The provisions of this rule apply to solid fuel burning devices in all areas within the jurisdiction of Olympic Region Clean Air Agency (ORCAA).

Rule 8.1.1 Definitions

     "Adequate Source of Heat" means a furnace or heating system, connected or disconnected from its energy source, designed with the ability to maintain seventy degrees Fahrenheit (70°F) at a point three (3) feet above the floor in all normally inhabited areas of a dwelling. Garages are specifically excluded.

     "Certified" means that a woodstove meets emission performance standards when tested by an accredited independent laboratory and labeled according to procedures specified by EPA in 40 CFR Part 60 Subpart AAA-Standards of Performance for Residential Wood Heaters as amended through July 1, 1990((; or Oregon Department of Environmental Quality Phase 2 emission standards contained in Subsections (2) and (3) of Section 340-21-115, and Oregon Administrative Rules, chapter 340, Division 21 -- Woodstove Certification dated November 1984)).

     (("Commercial" means a location that is licensed by the State of Washington to conduct business within the State of Washington.))

     "Cook Stove" means an appliance designed with the primary function of 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 cleanout below the firebox. Any device with a fan or heat channels used to dissipate heat into the room shall not be considered a cook stove.

     "Fireplace" means a permanently installed masonry fireplace; or a factory-built metal solid fuel burning device designed to be used with an open combustion chamber and without features to control the air to fuel ratio.

     "First Stage of Impaired Air Quality ((Stage 1))" means the same as Stage 1 burn ban and ((a condition)) is declared ((by the Control Officer)) when meteorological conditions are predicted to cause fine particulate ((10 microns and smaller in diameter, are at an ambient level of sixty (60))) levels to exceed 35 micrograms per cubic meter measured on a 24 hour average, within 48 hours. ((or when carbon monoxide is at an ambient level of eight parts of contaminant per million parts of air by volume measured on an eight hour average.))

     "Second Stage of Impaired Air Quality ((Stage 2))" means the same as Stage 2 burn ban and ((a condition)) is declared ((by the Control Officer)) when ((particulates 10 microns and smaller in diameter are at an ambient level of 105 micrograms per cubic meter measured on a 24 hour average.)) a first stage of impaired air quality has been in force and has not been sufficient to reduce the increasing fine particulate pollution trend (RCW 70.94.473). A second stage burn ban may be called without calling a first stage burn ban only when all of the following occur (RCW 70.94.473 (c)(ii):

     (a) Fine particulate levels have reached or exceeded 25 micrograms per cubic meter, measured on a 24 hour average:

     (b) Meteorological conditions have caused fine particulate levels to rise rapidly;

     (c) Meteorological conditions are predicted to cause fine particulate levels to exceed the 35 micrograms per cubic meter, measured on a 24 hour average, within 24 hours; and,

     (d) Meteorological conditions are highly likely to prevent sufficient dispersion of fine particulate.

     "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 CFR Part 60 Appendix A, Reference Method 28A-Measurment of Air to Fuel Ratio and minimum achievable burn rates for wood fired appliances as amended through July 1, 1990.

     "Salt Laden Wood" means any species of wood that has been soaked in salt water.

     "Seasoned Wood" means clean, untreated wood of any species that has been sufficiently dried so as to contain twenty percent (20%) or less moisture by weight.

     "Solid Fuel Burning Device" means a device that burns seasoned wood, coal, or any other nongaseous or nonliquid fuels((, and includes any device burning any solid fuel)) except those prohibited by Rule 8.1.3. 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. A cook stove is specifically excluded from this definition.

     "Treated Wood" means wood of any species that has been chemically impregnated, painted, or similarly modified to improve structural qualities or resistance to weathering or deterioration.

     "Woodstove" means an enclosed solid fuel burning device capable of and intended for ((residential)) space heating and/or domestic water heating. ((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.))

Rule 8.1.2 ((Opacity)) General Emission Standards

     (a) No person shall cause or allow an emission from a solid fuel burning device that unreasonably interferes with the use and enjoyment of property or workplace.

     (b) No person shall cause or allow emission of a smoke plume from any solid fuel burning device to exceed an average of twenty percent (20%) opacity ((for six consecutive minutes in any one hour period)) as determined by EPA Method 9. The provision of this requirement shall not apply during the starting of a new fire for a period not to exceed 20 minutes in any 4 hour period.

     (c) ((Enforcement.)) Smoke visible from a chimney, flue, or exhaust duct, in excess of the opacity standard shall constitute prima facie evidence of unlawful operation of an applicable solid fuel burning device. This presumption may be refuted by demonstration that the smoke was not caused by an applicable solid fuel burning device. ((The provision of this requirement shall not apply during the starting of a new fire for a period not to exceed twenty (20) minutes in any four hour period.))

Rule 8.1.3 Prohibited Fuel Types

     (a) ((A solid fuel burning device shall only burn clean, dry, untreated, and seasoned wood. Paper is allowed only for starting the fire.))

     (b) A person shall not cause or allow any of the following materials to be burned in a solid fuel burning device:

     (a) Garbage;

     (b) Treated wood;

     (c) Plastic products;

     (d) Rubber products;

     (e) Animals;

     (f) Asphalt products;

     (g) Petroleum products;

Rule 8.1.4 Curtailment

     (a) Whenever the ((Authority)) Agency has declared a((n Impaired Air Quality)) Stage 1 burn ban for a geographic area, a person ((in a residence or commercial establishment)) within that geographic area with an adequate source of heat other than a solid fuel burning device shall not operate any solid fuel burning device, unless the solid fuel burning device is one of the following:

     (1) Certified; or

     (2) A nonaffected pellet stove.

     (b) Whenever the ((Authority)) Agency has declared a((n Impaired Air Quality)) Stage 2 burn ban for a geographic area, a person ((in a residence or commercial establishment)) within that geographical area with an adequate source of heat other than a solid fuel burning device shall not operate any solid fuel burning device.

     (c) The affected geographic area of a declared Impaired Air Quality shall be determined by the ((Control Officer)) Executive Director or their designee.

     (d) A person responsible for an applicable solid fuel burning device already in operation at the time Impaired Air Quality is declared shall withhold new solid fuel for the duration of the Impaired Air Quality. Smoke visible from a chimney, flue, or exhaust duct after three hours has elapsed from the declaration of the Impaired Air Quality shall constitute prima facie evidence of unlawful operation of an applicable solid fuel burning device. This presumption may be refuted by demonstration that the smoke was not caused by a solid fuel burning device.

     (e) For the sole purpose of a contingency measure to meet the requirements of Section 172 (c)(9) of the Federal Clean Air Act, the use of solid fuel burning devices, except fireplaces as defined in RCW 70.94.453(3), woodstoves meeting the standards set forth in RCW 70.94.457 or pellet stoves either certified or issued an exemption by the EPA in accordance with Title 40, Part 60 of the Code of Federal Regulations will be prohibited if the EPA, in consultation with Ecology and the ((Authority)) Agency, makes written findings that:

     (1) The area has failed to make reasonable further progress or attain or maintain a national ambient air quality standard; and,

     (2) Emissions from solid fuel burning devices from a particular geographic area are a contributing factor to such failure to make reasonable further progress or attain or maintain a national ambient air quality standard.

     (3) A prohibition issued under 8.1.4(e) shall not apply to a person that does not have an adequate source of heat without burning wood.

     (4) The area is to consist of all areas within the city limits of Lacey, Olympia, and Tumwater and unincorporated areas of Thurston County lying within or between the municipal boundaries.

     ((A prohibition issued under this rule shall not apply to a person in a residence or commercial establishment that does not have an adequate source of heat without burning wood.

     (f) The nonattainment area is to consist of all areas within the city limits of Lacey, Olympia and Tumwater and unincorporated areas of Thurston County lying within or between the municipal boundaries.

     (g) A person responsible for an applicable solid fuel burning device already in operation at the time Impaired Air Quality is declared shall withhold new solid fuel or the duration of the Impaired Air Quality. Smoke visible from a chimney, flue, or exhaust duct after three hours has elapsed from the declaration of the Impaired Air Quality shall constitute prima facie evidence of unlawful operation of an applicable solid fuel burning device. This presumption may be refuted by demonstration that the smoke was not caused by a solid fuel burning device.))


Rule 8.1.5 Exemptions

     Written exemptions granted by the ((Authority)) Agency shall be valid for one (1) year from date of issue. Exemptions may be canceled at any time if the original request is found to be incorrect, inaccurate or fraudulent. Exemptions shall apply only to the use of solid fuel burning device during an Impaired Air Quality and not to the other rules of this regulation or other applicable regulations.

     (a) Emergency exemption. In an emergency situation the ((Authority)) Agency may issue a written solid fuel burning device emergency exemption. An emergency situation shall include, but is not limited to, a situation where a person demonstrates that their heating system, other than a solid fuel heating device, is inoperable for reasons other than their own actions or a situation where the heating system has been involuntarily disconnected by a utility company or other fuel supplier. ((An emergency exemption shall not exceed one year.))

     (b) Inadequate heat source. Written exemptions may be issued by the ((Authority)) Agency if a person can demonstrate that:

     (1) The structure was originally designed with a solid fuel burning device as the source of heat; or

     (2) The existing heat source, fueled with other than solid fuel, will not provide adequate heat.


Rule 8.1.6 Penalties

     A person in violation of this Rule 8.1 may be subject to the provisions of Rule 2.5.


Rule 8.1.7 Sale and Installation of Uncertified Woodstoves

     It shall be unlawful to install, sell, offer for sale, advertise for sale, or otherwise transfer an uncertified solid fuel burning device, except cook stoves, to another person or business to be operated in new or existing buildings or structures, unless the device has been rendered permanently inoperable. ((Uncertified solid fuel burning devices installed after January 1, 1992, shall be in violation of this rule and shall be promptly removed from the structure.))


Rule 8.1.8 ((Sale and)) Disposal of Uncertified Woodstoves

     At such time as an uncertified solid fuel burning device is to be permanently removed from its location it shall be rendered inoperable as a solid fuel burning device. A removed uncertified solid fuel burning device shall not be sold, bartered, traded, or given away for a purpose other than recycling of the materials to form something other than an uncertified solid fuel burning device.
