Name of Agency Personnel Responsible for Drafting and Implementation: Paul Mairose, Southwest Air Pollution

Control Authority, 1308 N.E. 134th Street, Vancouver, WA, (360) 374-3058 [574-3058]; and Enforcement: Robert D. Elliott, Southwest Air Pollution Control Authority, 1308 N.E. 134th Street, Vancouver, WA, (360) 574-3058.

Name of Proponent: Southwest Air Pollution Control Authority, governmental.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: SWAPCA 400-030 Definitions, this is an existing section. Proposed changes include adding more language to the definition of "air contaminant" to include "criteria pollutant"; updating dates of adoption for references to existing federal rules; adding a new definition for "PM_2.5" and "pollutant"; and adding additional substances to the exempt list of items for the definition of "volatile organic compound" consistent with the federal definition.

SWAPCA 400-040 General Standards for Maximum Emissions, this is an existing section. The proposed change is to add reference to a proposed method (SWAPCA Method 9 as an attachment to SWAPCA 400) for determining visible emissions. The method is similar to EPA Method 9 but contains the Washington state standard for data reduction. In addition, SWAPCA is proposing to delete the exemption for sources which are not capable of meeting the state standard for sulfur dioxide. Currently all sources in SWAPCA jurisdiction are capable of meeting the state standard.

SWAPCA 400-052 Stack Sampling of Major Combustion Sources, this is an existing rule. The proposed change is to add reference to SWAPCA 400-106 which contains requirements on how to perform emissions sampling.

SWAPCA 400-060 Emission Standards for General Process Units, this is an existing rule. The proposed change is to update the adoption date of the federal standard for source testing methods.

SWAPCA 400-070 Emission Standards for Certain Source Categories, this is an existing rule. The proposed changes are to remove reference to SWAPCA 400-110(8) for gasoline dispensing facilities because this section is proposed to be removed from the rules, and to adopt a new rule for dry cleaning operations to be consistent with the existing federal requirements.

SWAPCA 400-075 Emission Standards for Sources Emitting Hazardous Air Pollutants, this is an existing rule. The proposed changes include updating the adoption date of the federal standards for hazardous air pollutants and include source categories for which new federal standards have been promulgated.

SWAPCA 400-076 Emission Standards for Sources Emitting Toxic Air Pollutants, this is an existing rule. The proposed changes are to change the reference from SWAPCA 460 to chapter 173-460 WAC to be more precise about the adoption status by SWAPCA of the existing state rule.

SWAPCA 400-091 Voluntary Limits on Emissions, this is an existing rule. The proposed change is to add language to clarify that a voluntary limit may be requested for a process parameter of throughput in addition to emissions of air pollutants.

Proposal Changes the Following Existing Rules: See above.

No small business economic impact statement has been prepared under chapter 19.85 RCW. Changes proposed by the Southwest Air Pollution Control Authority are consistent with federal or state rules already in effect. This agency is not subject to the small business economic impact provision of chapter 19.85 RCW. A fiscal analysis has been performed to establish the basis for any proposed fee increases. Copies of this analysis are available at the Southwest Air Pollution Control Authority.

RCW 34.05.328 does not apply to this rule adoption. Pursuant to RCW 70.94.141(1), section 201, chapter 403, Laws of 1995, does not apply to this rule adoption. The Southwest Air Pollution Control Authority is not voluntarily invoking section 201, chapter 403, Laws of 1995.

Hearing Location: Office of the Southwest Air Pollution Control Authority, 1308 N.E. 134th Street, Vancouver, WA 98685, on October 1, 1998, at 3:00 p.m.

AMENDATORY SECTION

SWAPCA 400-030 Definitions

[Statutory Authority: Chapter 70.94.030 RCW, 70.94.141 RCW and 70.94.331 RCW. Original adoption by Board 12/17/68 (Regulation 1); Amended by Board 10/29/69 (Regulation 2); Amended by Board 3/20/84; Amended by Board 12/16/86; 93-21-003 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95]

Except as provided elsewhere in this regulation the following definitions apply throughout the regulation:

(1) "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 two-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 any 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. (2) "Adverse impact on visibility" means visibility impairment which interferes with the management, protection, preservation, or enjoyment of the visitor's visual experience of a 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.

(3) "Air contaminant" means dust, fumes, mist, smoke, other particulate matter, vapor, gas, odorous substance, or any combination thereof. This includes any substance regulated as an air pollutant under WAC 173-460, NESHAPS, Section 112 of the Federal Clean Air Act Amendments or substance for which a primary or secondary National Ambient Air Quality Standard has been established and volatile organic compounds. "Air pollutant" means the same as "air contaminant". A criteria pollutant is an air pollutant for which a criteria document has been prepared by EPA and has a primary or secondary ambient air quality standard. These pollutants are identified at 40 CFR Part 50 and include sulfur oxides (measured as sulfur dioxide), particulate matter, carbon monoxide, ozone, nitrogen dioxide, and lead. Volatile organic compounds as a category are no longer identified as a criteria pollutant.

(4) "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, or property, or which unreasonably interferes with enjoyment of life and property. For the purposes 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 various pesticides.

(5) "Allowable emissions" means the emission rate of a stationary source calculated using the maximum rated capacity of the source (unless the source is subject to federally enforceable limits 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, 61, or 63;

(b) Any applicable State Implementation Plan emission limitation including those with a future compliance date; (c) The emissions rate specified as a federally enforceable permit condition, including those with a future compliance date; or

(d) The emission rate specified by an applicable regulatory order.

(6) "Ambient air" means the surrounding outside air. (7) "Ambient air quality standard" (AAQS) means an established concentration, exposure time, and frequency of occurrence of an air contaminant or multiple air contaminants in the ambient air which shall not be exceeded.

(8) "Authority" means the Southwest Air Pollution Control Authority (SWAPCA).

(9) "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 regulation under Chapter 70.94 RCW which would be emitted from or which results from any new or modified stationary source, which the Authority, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes and available methods, systems, and techniques, including fuel cleaning or treatment, clean fuels, or innovative fuel combustion techniques for control of each such pollutant. In no event shall application of the "best available control technology" result in emissions of any air pollutants which will exceed the emissions allowed by any applicable standard under 40 CFR Part 60, Part 61, and Part 63 as they exist on August 1, 19968, or their later enactments as adopted by reference by the Authority by rule. Emissions from any source utilizing clean fuels, or any other means, to comply with this paragraph shall not be allowed to increase above levels that would have been required under the definition of BACT in the Federal Clean Air Act as it existed prior to enactment of the Clean Air Act Amendments of 1990.

(10) "Best available retrofit technology (BART)" means an 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 stationary facility. 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 non-air 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.

(11) "Board" means the Board of Directors of the Southwest Air Pollution Control Authority.

(12) "Bubble" means a set of emission limits which allows an increase in emissions from a given emissions unit(s) in exchange for a decrease in emissions from another emissions unit(s), pursuant to RCW 70.94.155, and SWAPCA 400-120.

(13) "Capacity factor" means the ratio of the average load on a machine or equipment for the period of time considered, to the manufacturer's capacity rating of the machine or equipment. (14) "Class I area" means any area designated pursuant to §§ 162 or 164 of the Federal Clean Air Act as a Class I area. The following areas are the Class I areas potentially affected by emissions from sources within SWAPCA jurisdiction:

Alpine Lakes Wilderness;

Glacier Peak Wilderness;

Goat Rocks Wilderness;

Mount Adams Wilderness;

Mount Rainier National Park;

Mt. Hood Wilderness Area;

Mt. Jefferson Wilderness Area.

(15) "Closure" means permanently stopping or terminating all processes at a facility. Such termination of processes shall result in no emissions of pollutants to the ambient air. Closure does not mean temporary shutdown of operations. A facility shall be considered "permanently closed" if operations have ceased and registration fees are not paid as set forth in SWAPCA 400-100(2)(e). Process and pollution control equipment may remain in place and on site but shall be configured such that the equipment or processes are incapable of generating emissions to the atmosphere (e.g. disconnection of power to equipment, mechanical positioning that inhibits processing; placing of padlocks on equipment to prevent operation). Closure of a facility requires notification to SWAPCA in accordance with SWAPCA 400-100(2)(d). New Source Review and applicable emission control technology requirements in accordance with current requirements for similar facilities will be required of the facility prior to restart if the annual registration fee is not paid.

(16) "Combustion and incineration sources" means emissions units using combustion for waste disposal, steam production, chemical recovery or other process requirements, but excludes open burning.

(17) "Commenced construction" means that an owner or operator has all the necessary preconstruction approvals or permits and either has:

(a) Begun, or caused to begin, a continuous program of actual on-site construction of the source, to be completed within a reasonable time; or

(b) Entered into binding agreements or contractual obligations, which cannot be cancelled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time. (ref. 40 CFR 52.21)

(18) "Concealment" means any action taken to reduce the observed or measured concentrations of a pollutant in a gaseous effluent while, in fact, not reducing the total amount of pollutant discharged.

(19) "Construction" means any physical change or change in the method of operation (including fabrication, erection, installation, demolition, or modification of an emissions unit) which would result in a change in actual emissions. (ref 40 CFR 52.21)

(20) "Control Officer" means the Executive Director of the Southwest Air Pollution Control Authority.

(21) "Director" means the director of the Washington State Department of Ecology or duly authorized representative.

(26) "Emission reduction credit (ERC)" means a credit granted pursuant to SWAPCA 400-131. This is a voluntary reduction in emissions beyond required levels of control. ERCs may be sold, leased, banked for future use or traded in accordance with applicable regulations. Emission reduction credits shall provide an incentive for reducing emissions below the required levels and to establish a framework to promote a market based approach to air pollution control.

(27) "Emission standard" and "emission limitation" mean a requirement established under the FCAA or Chapter 70.94 RCW or local regulation which limits the quantity, rate, or concentration of emissions of air contaminants on a continuous basis, including any requirement relating to the operation or maintenance of a source to assure continuous emission reduction and any design, equipment, work practice, or operational standard promulgated under the FCAA or Chapter 70.94 RCW.

(28) "Emissions unit" means any part of a stationary source which emits or would have the potential to emit any pollutant subject to regulation under the FCAA, Chapter 70.94 RCW or Chapter 70.98 RCW.

SWAPCA 400-040 General Standards for Maximum Emissions

[Statutory Authority: Chapter 70.94.040 RCW, 70.94.141 RCW, 70.94.154 RCW, and 70.94.331 RCW. Original adoption by Board 12/17/68 (Regulation 1); Amended by Board 10/29/69 (Regulation 2); Amended by Board 12/18/79; Amended by Board 3/20/84; 93-21-003 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95]

All sources and emissions units are required to meet the emission standards of this section. Where an emission standard listed in another section is applicable to a specific emissions unit, such standard shall take precedent over a general emission standard listed in this section. When two or more emissions units are connected to a common 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 stack 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 determined for some sources or source categories to be more stringent than the applicable emission limitations of this regulation or any chapter of Title 173 WAC. Where current controls are determined to be less than RACT, the Authority shall, as provided in RCW 70.94.154, define RACT for each source or source category and issue a rule or regulatory order requiring the installation of RACT.

(1) Visible emissions. No person shall cause or permit the emission for more than three minutes, in any one hour, of an air contaminant from any emissions unit which at the emission point, or within a reasonable distance of the emission point, exceeds twenty percent opacity as determined in accordance with Appendix A by a Certified Observer certified in accordance with EPA Method 9 "Visual Determination of the Opacity of Emissions from Stationary Sources" as specified in 40 CFR 60 Appendix A except: (a) When the emissions occur due to soot blowing/grate cleaning and the operator can demonstrate that the emissions will not exceed twenty 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 operation of boiler facilities. This practice, except for testing and trouble shooting, is to be scheduled for the same approximate times each day and the Authority shall be advised of the schedule.

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

(c) When two or more sources are connected to a common stack, the Authority may allow or require the use of an alternate time period if it is more representative of normal operations. (d) When an alternate opacity limit has been established 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 control of the owner(s) or operator(s) of the source in sufficient quantity to interfere unreasonably 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 operation which is a source of fugitive emission:

(a) If located in an attainment area and not impacting any nonattainment area, shall take reasonable precautions to prevent the release of air 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 shall 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.

(a) Any person who shall cause or allow the generation of any odor from any source, which may unreasonably interfere with any other property owner's use and enjoyment of his property must use recognized good practice and procedures to reduce these odors to a reasonable minimum.

(b) A scentometer No. 1 odor strength or equivalent dilution in residential and commercial areas shall not be exceeded.

(c) A scentometer No. 3 odor strength or equivalent dilution in all other land use areas shall not be exceeded.

(d) A violation of this section shall have occurred when two measurements made within a period of one (1) hour, separated by at least fifteen (15) minutes, off the property surrounding the air contaminant source exceeds the scentometer limitations set hereunder.

(e) When the source is a manufacturing process, no violation of this section shall have occurred provided that Best Available Control Technology (BACT), Maximum Available Control Technology (MACT), or Lowest Achievable Emission Rate (LAER), as applicable for odor control and abatement, is provided and is operating in compliance with other applicable regulations and emission limits. (f) When the source is using "good agricultural practices", as provided in RCW 70.94.640, no violation of this section shall have occurred.

(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 detrimental 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 gas containing sulfur dioxide from any emissions unit in excess of one thousand ppm of sulfur dioxide on a dry basis, corrected to seven percent oxygen or twelve percent CO₂ as required by the applicable emission standard for combustion sources, and based on the average of any period of sixty consecutive minutes ((, except:

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

(b) When a source limits such emission by a combination of constant emission controls and dispersion techniques approved by the Authority)).

(7) Concealment and masking. No person shall cause 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 section.

(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 shall maintain and operate the source to minimize emissions.

(b) The owner(s) or operator(s) of any existing source(s) of fugitive dust that has been identified as a significant contributor to a PM₁₀ nonattainment area shall be required to use reasonably available control technology (RACT) to control emissions. Significance will be determined by the criteria found in SWAPCA 400-113(3).

(3) Emissions Sampling Requirements. The owner or operator of a major combustion or incineration source identified in (2) shall cause or conduct emissions tests at least once every two calendar years to quantify emissions of the pollutants for which the source has been designated major. In the event that the combined emissions of a single pollutant from several emissions units establishes the source as major, emissions tests shall be conducted at least once every two calendar years for all emissions units which emit 30 percent or more of the emissions of the pollutant for which the source has been designated major. Emissions testing shall be performed in accordance with SWAPCA 400-106.

(4) Sampling Methods. All emissions tests shall be conducted in accordance with the specific test methods approved in advance by the Authority.

AMENDATORY SECTION

SWAPCA 400-076 Emissions Standards for Sources Emitting Toxic Air Pollutants

[Statutory Authority: Chapter 70.94.141 RCW and 70.94.331 RCW. Original Board adoption 95-17-084 filed 8/21/95, effective 9/21/95]

(1) The term toxic air pollutants (TAP) or toxic air contaminant means any air pollutant listed in ((SWAPCA)) WAC 173-460-150 or 460-160. The term toxic air pollutant may include particulate matter and volatile organic compounds if an individual substance or a group of substances within either of these classes is listed in ((SWAPCA)) WAC 173-460-150 or 460-160. The Chemical Abstract Service (CAS) number shall be the primary means used to specifically identify a substance. The term toxic air pollutant does not include particulate matter and volatile organic compounds as generic classes of compounds.

(2) All sources subject to the requirements of SWAPCA 400-110, 400-111, 400-112, 400-113 or 400-114 shall be subject to the requirements of ((SWAPCA)) WAC 173-460. All sources subject to review under SWAPCA 400 shall also be reviewed for applicability and/or compliance under ((SWAPCA)) WAC 173-460.

(3) The New Source Review fee schedule provided in SWAPCA 400-110 shall be applicable to all sources subject to ((SWAPCA)) WAC 173-460. The fees identified in SWAPCA 400-110 shall not be duplicate to any fees collected under ((SWAPCA)) WAC 173-460. Only a single fee shall apply to sources that are subject to SWAPCA 400 and ((SWAPCA)) WAC 173-460.

(4) A Notice of Construction is a written application to request approval for construction or modification of an air contaminant source. If a Notice of Construction application is required under both SWAPCA 400 and ((SWAPCA)) WAC 173-460, then the applications shall be combined. All sources subject to ((SWAPCA)) WAC 173-460 shall file a Notice of Construction application in accordance with SWAPCA 400-109 "Notice of Construction Application" and SWAPCA 400-110 "New Source Review". (5) Authority actions including issuance of regulatory orders and enforcement actions for sources subject to ((SWAPCA)) WAC 173-460 shall be the same as those actions for sources subject to and identified in SWAPCA 400.

(6) Sources subject to ((SWAPCA)) WAC 173-460 shall be subject to the registration requirements of SWAPCA 400-100. Where a source is subject to both SWAPCA 400 and ((SWAPCA)) WAC 173-460, only one registration shall be provided and only one fee shall be collected in accordance with the schedule outlined in SWAPCA 400-100.

AMENDATORY SECTION

SWAPCA 400-091 Voluntary Limits on Emissions

[Statutory Authority: Chapter 70.94.141 RCW and 70.94.331 RCW. Section previously numbered SWAPCA 400-090 - 93-21-003 filed 10/7/93, effective 11/8/93; 95-17-084 filed 8/21/95, effective 9/21/95]

(1) Voluntary limits on emissions and limitations on potential to emit or process parameters or throughputs may be requested by a source by submittal of a complete Notice of Construction application to the Authority as provided in SWAPCA 400-109. Confidential information shall be identified as set forth in SWAPCA 400-270. Upon request by the owner or operator of a source, and completion of review of the application by the Authority, the Authority shall issue a regulatory order which reduces that source's potential to emit to an amount agreed to by the owner or operator and the Authority.

(2) A condition contained in an order issued under this section shall be less than the source's otherwise allowable annual emissions of that air contaminant, process parameter or throughputs, under all applicable requirements of Chapter 70.94 RCW and the FCAA, including any standard or other requirement provided for in the Washington State Implementation Plan (SIP). (3) Any order issued under this section shall include monitoring, recordkeeping and reporting requirements sufficient to ensure that the source complies with any emission limit, process parameter or throughput, established under this section. Monitoring requirements shall use terms, test methods, units, averaging periods, and other statistical conventions consistent with the requirements of SWAPCA 400-105.

(4) Any order issued under this section shall be subject to the public notice and comment procedures under SWAPCA 400-171. (5) The terms and conditions of a regulatory order issued under this section shall be federally enforceable, upon approval of this section as an element of the Washington State Implementation Plan. Any proposed increase in emissions above limits contained in an order issued under this section shall require revision or revocation of the order.

(6) Noncompliance with any emission limit, test requirement, reporting requirement or other requirement identified in a regulatory order issued pursuant to this section shall be considered a violation of this section.
