(a) In general, actual emissions as of a particula r date shall equal the average rate, in tons per year, at which the emissions unit actually emit ted the pollutant during a two-year period which precedes the particular date and which is representative of normal source operation. Ecology or an authority shall allow the use of a different time period upon a determination that it is more representative of nor mal source operation. Actual emissions shall be calculated using the emissions unit's actu al operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(b) Ecology or an authority may presume that sourc e-specific allowable emissions for the unit are equivalent to the actual emissions of the emissions unit.

(c) For any emissions unit which has not begun nor mal operations on the particular date, actual emissions shall equal the potential to emit of the emissions unit on that date.

(2) "Adverse impact on visibility" means visibilit y impairment which interferes with the management, protection, preservation, or enjoyment of the visitor's visual experience of the

Federal Class I area. This determination must be m ade on a case-by-case basis taking into account the geographic extent, intensity, duration, frequency, and time of visibility impairment, and how these factors correlate with (a) times of v isitor use of the Federal Class I area, and (b) the frequency and timing of natural conditions that red uce visibility.

173-400-040 General Standards for Maximum Emissions

.

All sources and emissions units are required to mee t the emission standards of this chapter. Where an emission standard listed in another chapte r is applicable to a specific emissions unit, such standard will take precedent over a general em ission standard listed in this chapter. When

two or more emissions units are connected to a comm on stack and the operator elects not to provide the means or facilities to sample emissions from the individual emissions units, and the

relative contributions of the individual emissions units to the common discharge are not readily distinguishable, then the emissions of the common s tack must meet the most restrictive standard of any of the connected emissions units. Further, all emissions units are required to use reasonably available control technology (RACT) which may be de termined for some sources or source categories to be more stringent than the applicable emission limitations of any chapter of Title 173ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 17 WAC. Where current controls are determined to be l ess than RACT, ecology or the authority shall, as provided in section 8, chapter 252, Laws of 1993, define RACT for each source or source category and issue a rule or regulatory order requi ring the installation of RACT.

(1) Visible emissions. No person shall cause or p ermit the emission for more than three minutes, in any one hour, of an air contaminant fro m any emissions unit which at the emission point, or within a reasonable distance of the emiss ion point, exceeds twenty percent opacity

except:

(a) When the emissions occur due to soot blowing/g rate cleaning and the operator can

demonstrate that the emissions will not exceed twen ty percent opacity for more than fifteen minutes in any eight consecutive hours. The intent of this provision is to permit the soot blowing and grate cleaning necessary to the operati on of boiler facilities. This practice, except for testing and trouble shooting, is to be s cheduled for the same approximate times each day and ecology or the authority be advised of the schedule.

(b) When the owner or operator of a source supplie s valid data to show that the presence of uncombined water is the only reason for the opac ity to exceed twenty percent.

(c) When two or more sources are connected to a co mmon stack, ecology or the authority may allow or require the use of an alternate time p eriod if it is more representative of normal operations.

(d) When an alternate opacity limit has been estab lished per RCW 70.94.331 (2)(c).

(2) Fallout. No person shall cause or permit the emission of particulate matter from any source to be deposited beyond the property under direct co ntrol of the owner(s) or operator(s) of the source in sufficient quantity to interfere unreason ably with the use and enjoyment of the property upon which the material is deposited.

(3) Fugitive emissions. The owner or operator of any emissions unit engaging in materials handling, construction, demolition or any other ope ration which is a source of fugitive emission:

(a) If located in an attainment area and not impac ting any nonattainment area, shall take reasonable precautions to prevent the release of ai r contaminants from the operation.

(b) If the emissions unit has been identified as a significant contributor to the nonattainment status of a designated nonattainment area, shall be required to use reasonable and available control methods, which sha ll include any necessary changes in technology, process, or other control strategies to control emissions of the contaminants for which nonattainment has been designated.

(4) Odors. Any person who shall cause or allow th e generation of any odor from any source which may unreasonably interfere with any other pro perty owner's use and enjoyment of hisADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 18 property must use recognized good practice and proc edures to reduce these odors to a reasonable

minimum.

(5) Emissions detrimental to persons or property. No person shall cause or permit the emission of any air contaminant from any source if it is det rimental to the health, safety, or welfare of any person, or causes damage to property or business.

(6) Sulfur dioxide. No person shall cause or permit the emission of a g as containing sulfur dioxide from any emissions unit in excess of one thousand ppm of sulfur dioxid e on a dry basis, corrected to seven percent oxygen for combustion sources, and based on the ave rage of any period of sixty consecutive minutes, except:

When the owner or operator of an emissions unit sup plies emission data and can demonstrate to ecology or the authority that there is no feasible method of reducing the concentration to less than one thousand ppm (on a dry basis, corrected to seve n percent oxygen for combustion sources) and that the state and federal ambient air quality stan dards for sulfur dioxide will not be exceeded. In such cases, ecology or the authority may require sp ecific ambient air monitoring stations be established, operated, and maintained by the owner or operator at mutually approved locations. All sampling results will be made available upon re quest and a monthly summary will be submitted to ecology or the authority.

(7) Concealment and masking. No person shall caus e or permit the installation or use of any

means which conceals or masks an emission of an air contaminant which would otherwise violate any provisions of this chapter.

(8) Fugitive dust sources.

(a) The owner or operator of a source of fugitive dust shall take reasonable precautions to prevent fugitive dust from becoming airborne and sh all maintain and operate the source to

minimize emissions.

(b) The owner(s) or operator(s) of any existing so urce(s) of fugitive dust that has been identified as a significant contributor to a PM-10 nonattainment area shall be required to use reasonably available control technology to cont rol emissions. Significance will be determined by the criteria found in WAC 173-400-113 (3).

(4) Appeals: An order of approval, any conditions contained in an order of approval, or the denial of a notice of construction application may be appealed to the pollution control hearings board as provided in chapter 43.21B RCW. Ecology o r the authority shall promptly mail copies of each order approving or denying a notice of cons truction application to the applicant and to any other party who submitted timely comments on the ap plication, along with a notice advising parties of their rights of appeal to the Pollution Control Hearings Board and, where applicable, to the EPA Environmental Appeals Board.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 30 (5) Portable Sources: For portable sources which located temporarily at particular sites, the owner(s) or operator(s) shall be allowed to operate at the temporary location without filing a notice of construction application, providing that the own er(s) or operator(s) notifies ecology or the authority of intent to operate at the new location at least thirty days prior to starting the operatio n, and supplies sufficient information to enable ecolo gy or the authority to determine that the operation will comply with the emission standards f or a new source, and will not a cause a violation of applicable ambient air quality standar ds and , if in a nonattainment area, will not

interfere with scheduled attainment of ambient stan dards. The permission to operate shall be for a limited period of time (one year or less) and ecolo gy or the authority may set specific conditions for operation during that period. A temporary sour ce shall be required to comply with all applicable emission standards.

(6) Approval to construct or modify a stationary s ource shall become invalid if construction is not commenced within eighteen months after receipt of s uch approval, if construction is discontinued for a period of eighteen months or more, or if cons truction is not completed within a reasonable time.

WAC 173-400-112 Requirements for New Sources in Non attainment Areas.

Ecology or an authority reviewing an application to establish a new source or modification in a nonattainment area, shall issue an order of approva l, which order shall contain such conditions as are reasonably necessary to assure the maintenance of compliance with this chapter, if they determine that the proposed project satisfies each of the following requirements:

(1) The proposed new source or modification will co mply with all applicable new source performance standards, national emission standards for hazardous air pollutants, emission standards adopted under chapter 70.94 RCW and, for sources regulated by an authority, the applicable emission standards of that authority.

(2) The proposed new source will employ BACT for al l air contaminants, except that if the new source is a major stationary source or the proposed modification is a major modification it will

achieve LAER for the contaminants for which the are a has been designated nonattainment and for which the proposed new source or modification is ma jor.

(3) The proposed new source will not cause any ambi ent air quality standard to be exceeded, will not violate the requirements for reasonable further progress established by the state implementation plan and will comply with WAC 173-40 0-113(3) for all contaminants for which the area has not been designated nonattainment.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 31 (4) If the proposed new source is a major stationar y source or the proposed modification is a major modification, ecology or the authority has determin ed, based on review of an analysis performed by the source of alternative sites, sizes, producti on processes, and environmental control techniques, that the benefits of the project signif icantly outweigh the environmental and social costs imposed as a result of its location, construc tion, or modification.

(5) If the proposed new source or the proposed modi fication is major for the contaminant for which the area is designated nonattainment, allowable emi ssions from the proposed new source or modification of that contaminant are offset by redu ctions in actual emissions from existing sources

in the nonattainment area. Emission offsets must b e sufficient to ensure that total allowable emissions from existing major stationary sources in the nonattainment area, new or modified sources which are not major stationary sources, and the proposed new or modified source will be less than total actual emissions from existing sour ces (prior to submittal of the application) so as t o represent (when considered together with the nonatt ainment provisions of section 172 of the FCAA) reasonable further progress. All offsetting emission reductions must satisfy the following requirements:

(a) The proposed new level of allowable emissions o f the source or emission unit(s) providing the reduction must be less than the curre nt level of actual emissions of that source or emissions unit(s). No emission reduction can be credited for actual emissions

which exceed the current allowable emissions of the source or emissions unit(s) providing the reduction. Emission reductions imposed by loca l, state, or federal regulations, regulatory orders, or permits cannot be credited.

(b) The emission reductions must provide for a net air quality benefit. For marginal ozone nonattainment areas, the total emissions of volatil e organic compounds or total emissions of nitrogen oxides are reduced by a ratio of 1.1 to 1 for the area in which the new source is located. For any other nonattainment area, the emi ssions offsets must provide a positive net air quality benefit in the nonattainment area. Determinations on whether emissions offsets provide a positive net air quality benefit will be made in accordance with the guidelines contained in 40 CFR 51 Appendix S.

(c) If the offsets are provided by another source, the reductions in emissions from that source must be federally enforceable by the time th e new or modified source commences operation. The new source may not commence operati on before the date such reductions are actually achieved. An emission reduction credi t issued under WAC 173-400-131 may be used to satisfy some or all of the offset requir ements of this subsection.

(6) If the proposed new source is a major stationar y source or the proposed modification is a major modification, the owner or operator has demonstrate d that all major stationary sources owned or operated by such person (or by any entity controlli ng, controlled by, or under common control with such person) in Washington are subject to emission limitations and are in compliance, or on a schedule for compliance, with all applicable emissi on limitations and standards under the FederalADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 32 Clean Air Act, including all rules contained in an EPA-approved state implementation plan.

(7) If the proposed new source is a major stationar y source or the proposed modification is a major modification for the purposes of the PSD program de scribed in WAC 173-400-141, it meets the requirements of that program for all contaminants f or which the area has not been designated

nonattainment.

(8) If the proposed new source or modification will emit any toxic air pollutants regulated under chapter 173-460 WAC, the source meets all applicabl e requirements of that chapter.

(9) If the proposed new source is a major stationar y source or the proposed modification is a major modification, ecology or the authority has complied with the visibility protection review requirements of 40 CFR 52.28(c) through (e) except for (c)(4)(i), (g), and (h), as in effect on March 3, 1993, and determined that the project meets the criteria set forth in 40 CFR 52.28(g). For purposes of this subsection, definitions referenced in 40 CFR 52.28(b) are incorporated by reference, except that the term "visibility protect ion area" means any Class I area, and terms defined in WAC 173-400-030 shall have the meanings defined in that section. References in 40 CFR 52.28 to "the Administrator" shall mean the age ncy (either ecology or the authority) processing the notice of construction application.

173-400-151 Retrofit Requirements for Visibility Pr otection.

(1) Determination of best available retrofit techn ology (BART). Ecology shall identify and analyze each source which may reasonably be anticip ated to cause or contribute to impairment of visibility in any mandatory Class I area in Washing ton and any adjacent state and to determine

BART for the contaminant of concern and those addit ional air pollution control technologies that are to be required to reduce impairment from the so urce.

(2) Initially defined BART. The owner(s) or opera tor(s) of any source(s) to which significantADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 34 visibility impairment of a mandatory Class I area i s reasonably attributable shall apply BART for each contaminant contributing to visibility impairm ent that is emitted at more than 250 tons per year. Each source for which BART is required must install and operate BART as expeditiously as possible, but in no case later than five years afte r the conditions are included in a regulatory order

.

(3) Future definitions of BART. The owner(s) or o perator(s) of any source(s) to which significant visibility impairment of a mandatory Cl ass I area is reasonably attributable shall apply BART as new technology becomes available for a cont aminant if:

173-400-161 Compliance Schedules.

(1) Issuance. Whenever a source is found to be in violation of an emission standard or other provision of this chapter, ecology or the authority may issue a regulatory order requiring that the source be brought into compliance within a specifie d time. The order shall contain a schedule for installation, with intermediate benchmark dates and a final completion date, and shall constitute a compliance schedule. Requirements for public invol vement (WAC 173-400-171) must be met.

(2) Federal action. A source shall be considered to be in compliance with this chapter if all the provisions of its individual compliance schedule in cluded with a regulatory order are being met. Such compliance does not preclude federal enforceme nt action by the EPA until and unless the schedule is submitted and adopted as an amendment t o the state implementation plan.

(3) Penalties for delayed compliance. Sources on a compliance schedule but not meeting emissions standards may be subject to penalties as provided in the Federal Clean Air Act.

State effective: 3/22/91; EPA effective: 6/2/95

173-400-200 Creditable Stack Height & Dispersion Te chniques.

(1) Applicability. These provisions shall apply to all sources except:

(a) Stacks for which construction had commenced on or before December 31, 1970, except where pollutants are being emitted from such stacks used by sources which were constructed, or reconstructed, or for which major m odifications were carried out after December 31, 1970;

(b) Coal-fired steam electric generating units sub ject to the provisions of Section 118 of the Federal Clean Air Act, which commenced operatio n before July 1, 1957, and for whose stacks construction commenced before February 8, 19 74;

(c) Flares;

(d) Open burning for agricultural or silvicultural purposes as covered under the smoke management plan;

(e) Residential wood combustion and open burning f or which episodic restrictions apply.

These provisions shall not be construed to limit th e actual stack height.

(2) Prohibitions. No source may use dispersion te chniques or excess stack height to meet ambient air quality standards or PSD increment limi tations.

(a) Excess stack height. Excess stack height is t hat portion of a stack which exceeds the greater of:

(i) Sixty-five meters, measured from the ground le vel elevation at the base of the stack; or

(ii) H g .= H.+ 1.5L

where: H g .= "good engineering practice" (GEP) stack height, measured from the ground level elevation at the base of the stack,

H.= height of nearby structure(s) measured from the ground level elevation at the base of the stack,ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 38 L.= lesser dimension, height or projected width, of nearby structure(s), subject to the proviso below.

"Nearby," as used in this subsection for purposes o f applying the GEP formula means that distance up to five times the lesser of the height or the wi dth dimension of a structure, but not greater than 0.8 kilometer (1/2 mile).

(b) Dispersion techniques. Increasing final exhau st gas plume rise by manipulating source process parameters, exhaust gas parameters, stack parameters, or combining exhaust gases from several existing stacks into one stack; or other selective handling of exhaust gas streams so as to increase the exhaust g as plume rise. This does not include:

(i) The reheating of a gas stream, following the u se of a pollution control system, for the purpose of returning the gas to the tempera ture at which it was originally discharged from the facility generating the gas str eam;

(ii) The merging of gas streams where:

(A) The source was originally designed and constru cted with such merged gas streams, as demonstrated by the source owner(s) or operator(s).

(B) Such merging is part of a change in operation at the facility that includes the installation of pollution controls and is accompanied by a net reduction in the allowable emissions of a pollutant . This exclusion shall apply only to the emission limitation for the pollu tant affected by such change in operation.

(C) Before July 8, 1985, such merging was part of a change in operation at the facility that included the installation of emis sions control equipment or was carried out for sound economic or engineering r easons, and not primarily motivated by an intent to gain emissions credit for greater dispersion.

(3) Exception. EPA, ecology, or an authority may require the use of a field study or fluid model to verify the creditable stack height for the sourc e. This also applies to a source seeking credit

after the effective date of this rule for an increa se in existing stack height up to that established by the GEP formula. A fluid model or field study shal l be performed according to the procedures

described in the EPA Guideline for Determination of Good Engineering Practice Height (Technical Support Document of the Stack Height Reg ulations). The creditable height demonstrated by a fluid model or field study shall ensure that the emissions from a stack do not result in excessive concentrations of any air pollu tant as a result of atmospheric downwash, wakes, or eddy effects created by the source itself, nearb y structures or nearby terrain features.

(a) "Nearby," as used in this subsection for conduc ting a field study or fluid model, meansADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 39 not greater than 0.8 km, except that the portion of a terrain feature may be considered to be nearby which falls within a distance of up to ten t imes the maximum height of the feature,

not to exceed two miles if such feature achieves a height 0.8 km from the stack that is at least forty percent of the GEP stack height or twen ty-six meters, whichever is greater, as measured from the ground-level elevation at the bas e of the stack. The height of the structure or terrain feature is measured from the g round-level elevation at the base of the

stack.

(b) "Excessive concentration" is defined for the p urpose of determining creditable stack height under this subsection and means a maximum gr ound-level concentration owing to a significant downwash effect which contributes to ex cursion over an ambient air quality standard. For sources subject to PSD review (WAC 1 73-400-141 and 40 CFR 52.21) an excessive concentration alternatively means a maxim um ground-level concentration owing to a significant downwash effect which contributes to excursion over a PSD increment.

The emission rate used in this demonstration shall be the emission rate specified in the state implementation plan, or in the absence of such, the actual emission rate of the source. "Significant downwash effect" means a maximum groun d-level concentration due to emissions from a stack due in whole or in part to d ownwash, wakes, and eddy effects produced by nearby structures or nearby terrain fea tures which individually is at least forty percent in excess of the maximum concentration expe rienced in the absence of such downwash, wakes, or eddy effects.

(b) Penalties incurred but not paid shall accrue i nterest, beginning on the ninety-first day following the date that the penalty becomes due and payable, at the highest rate allowed by RCW 19.52.020 on the date that the penalty becomes due and payable. If violations or penalties are appealed, interest shall not begin to accrue until the thirty-first day following final resolution of the appeal.

The maximum penalty amounts established in RCW 70.9 4.431 may be increased annually to account for inflation as determined by the state office of the economic and revenue

forecast council.

(c) Each act of commission or omission which procu res, aids, or abets in the violation shall be considered a violation under the provision s of this section and subject to the same penalty. The penalties provided in this section sh all be imposed pursuant to RCW

43.21B.300.

(d) All penalties recovered under this section by ecology shall be paid into the state treasury and credited to the air pollution control account established in RCW 70.94.015 or, if recovered by the authority, shall be paid into t he treasury of the authority and credited to its funds. If a prior penalty for the same violati on has been paid to a local authority, the penalty imposed by ecology under subsection (a) of this section shall be reduced by the amount of the payment.

(e) To secure the penalty incurred under this sect ion, the state or the authority shall have a lien on any vessel used or operated in violation of this chapter which shall be enforced as provided in RCW 60.36.050.

(f) Public or private entities that are recipients or potential recipients of ecology grants, whether for air quality related activities or not, may have such grants rescinded or withheld by ecology for failure to comply with provisions of this chapter.

(g) In addition to other penalties provided by thi s chapter, persons knowingly under-reporting emissions or other information used to set fees, or persons required to pay emission or permit fees who are more than ninety da ys late with such payments may be subject to a penalty equal to three times the amoun t of the original fee owed.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 42 (3) Assurance of discontinuance. Personnel of eco logy or an authority may accept an assurance of discontinuance of any act or practice deemed in violation of this chapter. Any such assurance shall specify a time limit during which discontinua nce is to be accomplished. Failure to perform the terms of any such assurance shall constitute pr ima facie proof of a violation of this chapter or any order issued thereunder which make the alleged act or practice unlawful for the purpose of securing an injunction or other relief from the sup erior court.

(4) Restraining orders, injunctions. Whenever any person has engaged in, or is about to engage in, any acts or practices which constitute or will constitute a violation of any provision of this chapter, the director, after notice to such person and an opportunity to comply, may petition the superior court of the county wherein the violation is alleged to be occurring or to have occurred for a restraining order or a temporary or permanent inj unction or another appropriate order.

RULE 8.1 WOOD HEATING

Rule 8.1.1 Definitions

“Adequate Source of Heat” means a furnace or heating system, connected or dis connected from its energy source, designed with the ability to mai ntain seventy degrees Fahrenheit (70  F) at a point three (3) feet above the floor in all normall y inhabited areas of a dwelling. Garages are specifically excluded.

“Certified” means that a woodstove meets emission performance s tandards when tested by an accredited independent laboratory and labeled accor ding to procedures specified by EPA in 40 CFR Part 60 Subpart AAA-Standards of Performance fo r Residential Wood Heaters as amended through July 1, 1990.

“Cook Stove” means an appliance designed with the primary functi on of cooking food and containing an integrally built-in oven, with an int ernal 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 diss ipate 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 com bustion chamber and without features to

control the air to fuel ratio.

“First Stage of Impaired Air Quality” means the same as Stage 1 burn ban and is declared when meteorological conditions are predicted to cause fi ne particulate levels to exceed 35 micrograms per cubic meter measured on a 24 hour average, with in 48 hours.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 45 “Second Stage of Impaired Air Quality” means the same as Stage 2 burn ban and is declared when 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 particul ate levels to rise rapidly; (c) Meteorological conditions are predicted to cause fi ne 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 prev ent 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 i n 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 s alt 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 a ny other nongaseous or nonliquid fuels except those prohibit ed by Rule 8.1.3. This also includes devices used for aesthetic or a space heating purpose, whic h has a heat input less than one million British thermal units per hour. A cook stove is specificall y excluded from this definition.

“Treated Wood” mean wood of any species that has been chemically i mpregnated, 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 space heating and/or domestic water heating.

Rule 8.1.2 General Emission Standards

(a) No person shall cause or allow an emission fr om a solid fuel burning device that unreasonably interferes with the use and enjoymen t of property or workplace.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 46 (b) No person shall cause or allow emission of a smoke plume from any solid fuel burning device to exceed an average of twenty per cent (20%) opacity as determined by EPA Method 9. The provision of this requirement shall not apply during the starting of a new fire for a period no t to exceed 20 minutes in any 4 hour period.

(c) Smoke visible from a chimney, flue, or exhaus t duct, in excess of the opacity standard shall constitute prima facie evidence of unlawful operation of an applicable solid fuel burning device. This presum ption may be refuted by demonstration that the smoke was not caused by an applicable solid fuel burning

device.

State effective: 5/22/10; EPA effective: 11/4/13

Rule 8.1.3 Prohibited Fuel Types

A person shall not cause or allow any of the follow ing 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; (h) Paints and chemicals; (i) Salt laden wood; or (j) Any substance that normally emits dense smoke or obnoxious odors.

Rule 8.1.4 Curtailment

(a) Whenever the Agency has declared a Stage 1 bur n ban for a geographic area, a person within that geographic area with an adequate sourc e of heat other than a solid fuel burning device shall not operate any solid fuel burning de vice, unless the solid fuel burning device is one of the following:

(1) Certified; or (2) A nonaffected pellet stove.ADDITIONAL REGULATIONS APPROVED FOR THE OLYMPIC REG ION CLEAN AIR AGENCY (ORCAA) JURISDICTION – page 47 (b) Whenever the Agency has declared a Stage 2 bur n ban for a geographic area, a person within that geographical area with an adequate sou rce of heat other than a solid fuel burning device shall not operate any solid fuel bu rning device.

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

(d) A person responsible for an applicable solid f uel burning device already in operation at the time Impaired Air Quality is declared shall withho ld 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 A ir Quality shall constitute prima facie evidence of unlawful operation of an applicable so lid fuel burning device. This presumption may be refuted by demonstration that t he 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), woodsto ves 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 F ederal Regulations will be prohibited if the EPA, in consultation with Ecology and the Agen cy, makes written findings that:

(1) The area has failed to make reasonable furthe r progress or attain or maintain a national ambient air quality standard; and, (2) Emissions from solid fuel burning devices fro m a particular geographic area are a contributing factor to such failure to make reaso nable 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 th e city limits of Lacey, Olympia, and Tumwater and unincorporated areas of Thurston Cou nty lying within or between the municipal boundaries.
