AMENDATORY SECTION

SECTION 1.07 DEFINITIONS

When used in regulations of the Olympic Air Pollution Control Authority, the following definitions shall apply, unless they are preempted by definitions in individual Articles:

actual emissions means the actual rate of emissions of a pollutant from an emission unit, as determined in accordance with (a) through (c) of this subsection.

(a) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during a one year period which precedes the particular date and which is representative of normal source operation. The Authority shall allow the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissions shall be calculated using the emissions unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(b) The Authority may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the emissions unit.

(c) For an emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the emissions unit on that date.

adverse impact on visibility means visibility impairment which interferes with the management, protection, preservation, or enjoyment of the visitor visual experience of the Federal Class I area. This determination must be made 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 visitor use of the Federal Class I area, and (b) the frequency and timing of natural conditions that reduce visibility. This term does not include effects on integral vistas.

agricultural burning means burning of vegetative debris from an agricultural operation necessary for disease or pest control, necessary for crop propagation and/or crop rotation, or where identified as a best management practice by the agricultural burning practices and research task force established in RCW 70.94.650 or other authoritative source on agricultural practices.

agricultural operation means the growing of crops, the raising of fowl or animals as gainful occupation.

air contaminant means dust, fumes, mist, smoke, other particulate matter, vapor, gas, odorous substance, or any combination thereof. "Air pollutant" means the same as "air contaminant".

air pollution means the presence in the outdoor atmosphere of one or more air contaminants in sufficient quantities, and of such characteristics and duration as is, or is likely to be, injurious to human health, plant or animal life, property, or which unreasonably interferes with enjoyment of life and property. For the purpose of this Regulation, air pollution shall not include air contaminants emitted in compliance with chapter 17.21 RCW, the Washington Pesticide Application Act, which regulates the application and control of the use of various pesticides.

air pollution episode means a period when a forecast, alert, warning, or emergency air pollution state is declared, as stated in Chapter 173-435 WAC.

allowable emissions means the emission rate calculated using the maximum rated capacity of the source (unless the stationary source is subject to limits enforceable by the Authority which restrict the operating rate, or hours of operation, or both) and the most stringent of the following:

(a) The applicable standards as set forth in 40 CFR part 60 or 61;

(b) Any applicable state implementation plan emissions limitation including those with a future compliance date; or;

(c) The emissions rate specified in an approval order, permit condition, or regulatory order issued by the Authority including those with a future compliance date.

alteration means any addition to or enlargement or replacement; or any major modification or change of the design, capacity, process or arrangement; or any increase in the connected loading of equipment or control facility which will significantly increase or adversely affect the kind or amount of air contaminant emitted.

ambient air means that portion of the atmosphere external to a building to which the general public has access.

ambient air quality standard means an established concentration, exposure time, and frequency of occurrence of air contaminant(s) in the ambient air which shall not be exceeded.

best available control technology (bact) means an emission limitation (including a visible emission standard) based on the maximum degree of reduction for each air pollutant subject to this regulation which would be emitted from any proposed new or modified source which the permitting authority, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such sources or modification through application of production processes, available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such air pollutant. In no event shall application of the best available technology result in emissions of any air pollutant which would exceed the emissions allowed by any applicable standard under 40 CFR Part 60 and Part 61. If the reviewing authority determines that technological or economic limitations on the application of the imposition of an emission standard is infeasible, it may instead prescribe a design, equipment, work practice or operational standard, or combination thereof, to meet the requirement of BACT. Such standard shall, to the degree possible, set forth the emission reduction achievable by implementation of such design, equipment, work practice or operation and shall provide for compliance by means which achieve equivalent results. The term "all known available and reasonable methods of emission control" is interpreted to mean the same as best available control technology.

best available retrofit technology (bart) means any emission limitation based on the degree of reduction achievable through the application of the best system of continuous emission reduction for each pollutant which is emitted by an existing source. The emission limitation must be established, on a case-by-case basis, taking into consideration the technology available, the costs of compliance, the energy and nonair quality environmental impacts of compliance, any pollution control equipment in use or in existence at the source, the remaining useful life of the source, and the degree of improvement in visibility which may reasonably be anticipated to result from the use of such technology. If an emission limitation is not feasible, a design, equipment, work practice, operational standard, or combination thereof, may be required.

This includes any organic compound other than the following, which have negligible photochemical activity: Methane; ethane, methylene chloride (dichloromethane); 1,1,1-trichloroethane (methyl chloroform); 1,1,1-trichloro 2,2,2-trifluoroethane (CFC-113); trichlorofluoromethane (CFC-11); dichlorodifluoromethane (CFC-12); chlorodifluoromethane (CFC-22); trifluoromethane (FC-23); 1,1,2,2-tetrafluoroethane (CFC-114); chloropentafluoroethane (CFC-115); 1,1,1-trifluoro 2,2-dichloroethane (HCFC-123); 1,1,1,2-tetrafluoroethane (HCFC-124); pentafluoroethane (HFC-125); 1,1,2,2-tetrafluoroethane (HFC-134); 1,1,1-trifluoroethane (HFC-143a); 1,1-difluoroethane (HFC-152a); and perfluorocarbon compounds which fall into these classes:

(1) Cyclic, branched, or linear completely fluorinated alkanes;

(2) Cyclic, branched, or linear completely fluorinated ethers with no unsaturations; and

(3) Sulfur containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine.

(b) For the purpose of determining compliance with emission limits, VOC will be measured by the appropriate methods in 40 CFR Part 60 Appendix A. Where such a method also measures compounds with negligible photochemical reactivity, these negligibly reactive compounds may be excluded as VOC if the amount of such compounds is accurately quantified, and such exclusion is approved by the Authority.

(c) As a precondition to excluding these negligibly reactive compounds as VOC or at any time thereafter, Ecology or the Authority may require an owner or operator to provide monitoring or testing methods and results demonstrating, to the satisfaction of Ecology or the Authority, the amount of negligibly reactive compounds in the source's emissions.

waste means unproductive, worthless, useless or rejected material.

waste-wood burner means equipment or facility used solely for the combustion-disposal of waste wood without heat recovery. Such burners shall include, but not be limited to, a wigwam burner, a silo-type burner, or an air-curtain burner.

AMENDATORY SECTION

SECTION 8.03 DEFINITIONS

adequate source of heat means the ability to maintain seventy degrees Fahrenheit (70ºF) 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:

(a) EPA in 40 CFR Part 60 Subpart AAA-Standards of Performance for Residential Wood Heaters as amended through July 1, 1990; or

(b) 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.

impaired air quality stage 1 means a condition declared by the Control Officer when particulates, 10 microns and smaller in diameter, are at an ambient level of ((75)) sixty (60) micrograms per cubic meter measured on a 24 hour average 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.

impaired air quality stage 2 means a condition 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.

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-Measurement 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 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 nongaseous or nonliquid fuels, and includes any device burning any solid fuel except those prohibited by Section 8.07. This also includes devices used for aesthetic or spaceheating 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 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.
