Effective Date of Rule: Thirty-one days after filing.

     Purpose: SWCAA 400-030 Definitions. This is an existing section that contains the definitions of words and phrases used throughout SWCAA 400. The proposed revision expands the definition of "new source" to specifically include the installation or construction of an "emission unit." This change is intended to clarify and codify existing agency policy.

     SWCAA 400-045 Permit Application for Nonroad Engines. This is an existing section identifying requirements for permit applications for nonroad engine projects. The proposed revision corrects an inaccurate cross sectional rule reference.

     SWCAA 400-046 Application Review Process for Nonroad Engines. This is an existing section identifying requirements for the processing and approval of permit applications for nonroad engine projects. The proposed revision corrects an inaccurate cross sectional rule reference.

     SWCAA 400-075 Emission Standards for Sources Emitting Hazardous Air Pollutants. This is an existing section that adopts the federal standards for sources emitting hazardous air pollutants contained in 40 C.F.R. Parts 61, 63 and 65 by reference (NESHAPS/MACT) as requirements for sources in SWCAA jurisdiction for local implementation and enforcement. The proposed changes update adoption reference dates and incorporate new federal regulations contained in 40 C.F.R., Parts 61, 63 and 65.

     SWCAA 400-101 Emission Units Exempt from Registration Requirements. This is an existing section identifying those sources that are exempt from the registration and new source review requirements of SWCAA 400-100 and SWCAA 400-110. The proposed changes clarify the applicability language of the exemption section.

     SWCAA 400-111 Requirements for New Sources in a Maintenance Plan Area. This is an existing section identifying the requirements for new or modified sources in a maintenance plan area. The proposed revision significantly reformats this section to incorporate updated requirements consistent with the forthcoming ozone maintenance plan for the Portland/Vancouver area. This action is needed to support adoption of the ozone maintenance plan.

     SWCAA 400-113 Requirements for New Sources in Attainment or Nonclassifiable Areas. This is an existing section identifying the new source review requirements for new or modified sources in attainment areas. The proposed revision incorporates updated language regarding requirements for sources that impact a maintenance area. The changes are intended to support the forthcoming ozone maintenance plan for the Portland/Vancouver area. This action is needed to support adoption of the ozone maintenance plan.

     SWCAA 400-115 Standards of Performance for New Sources. This is an existing section that adopts by reference the New Source Performance Standards (NSPS) contained in 40 C.F.R. Part 60 for identified sources categories. The proposed changes update adoption reference dates and incorporate new federal regulations contained in 40 C.F.R., Part 60.

     SWCAA 400-141 Prevention of Significant Deterioration (PSD). This is an existing section describing the requirements for those sources that would be subject to the federal PSD permitting requirements and provides reference to the appropriate federal regulations. The proposed revisions update the adoption by reference rule citations to match the current format of the equivalent sections located in chapter 173-400 WAC.

     SWCAA 400-171 Public Involvement. This is an existing section identifying the requirements for public notice of agency actions, and the process by which public involvement is to be administered. The proposed revision removes minor permit modifications from the list of agency actions that require a mandatory public comment period. This action is intended to streamline public involvement requirements for minor modifications.

     SWCAA 400-200 Vertical Dispersion Requirement, Creditable Stack Height and Dispersion Techniques. This is an existing section identifying presumptive requirements for new exhaust stack installations, and describes the procedure by which the maximum allowable stack height is to be determined. The proposed revision establishes a presumptive requirement for vertical exhaust stack orientation. This action codifies elements of the agency's existing permitting policy.

     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 emission unit actually emitted the pollutant during a two-year period which precedes the particular date and which is representative of normal "source" operation. The Agency 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 emission unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

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

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

     (2) "Adverse impact on visibility" means visibility impairment that 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.

     (3) "Agency" means the Southwest Clean Air Agency (SWCAA).

     (4) "Air contaminant" or "air pollutant" 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 Chapter 173-460 WAC, Sections 111 and 112 of the Federal Clean Air Act, ozone depleting substances (Title VI of the Federal Clean Air Act), any substance for which a primary or secondary National Ambient Air Quality Standard has been established, and volatile organic compounds.

     (6) "Air discharge permit application" means the same as "Notice of Construction application." This term does not apply to any permitting action conducted pursuant to 40 CFR Part 70 or Chapter 173-401 WAC.

     (7) "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.

     (8) "Allowable emissions" means the emission rate of a "stationary source" calculated using the maximum rated capacity of the "stationary source" (unless the "stationary 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 in 40 CFR Parts 60, 61, or 63;

     (b) Any applicable State Implementation Plan (SIP) emission limitation including those with a future compliance date;

     (c) The emission rate specified as a federally enforceable permit condition, including those with a future compliance date; or

     (d) The emission rate specified by a federally enforceable regulatory order.

     (9) "Alteration" means the act of altering, which means to change or make different. Alteration includes, but is not limited to, any enlargement, replacement, or change in the design, operation, capacity, or arrangement of a process; any increase in the connected loading of process or control equipment; and any change in fuels, method of operation or hours of operation not previously approved by the Agency.

     (10) "Ambient air" means the surrounding outside air.

     (11) "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 that shall not be exceeded.

     (12) "Attainment area" means a geographic area designated by EPA at 40 CFR Part 81 as having attained the National Ambient Air Quality Standard for a given criteria pollutant.

Such activities include, but are not limited to, installation of building supports and foundations, laying underground pipe work and construction of permanent storage structures. With respect to a change in method of operations, this term refers to those on-site activities other than preparatory activities that mark the initiation of the change.

     (15) "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 Agency, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such "stationary 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 "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. Emissions from any "stationary 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.

     (16) "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 that 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 "stationary source," the remaining useful life of the "stationary source," and the degree of improvement in visibility which may reasonably be anticipated to result from the use of such technology.

     (17) "Board" means the Board of Directors of the Southwest Clean Air Agency.

SWCAA 400-111 Requirements for New Sources in a Maintenance Plan Area

[Statutory Authority: Chapter 70.94.141 RCW. Original Board adoption 95-17-084 filed 8/21/95, effective 9/21/95; 96-21-099 filed 10/21/96, effective 11/21/96; 99-07-028 filed 3/10/99, effective 4/11/99; 01-05-056 filed 2/15/01, effective 3/18/01; 03-21-045 filed 10/9/03, effective 11/9/03]

     For the purposes of this section, "major modification," "major stationary source," "net emissions increase," and "significant," shall have the same meaning as the definitions found in SWCAA 400-030, subsections (60)(a), (61)(a), (71)(a) and (107)(a) respectively.

     An air discharge permit application to establish a "new source", install or replace an "emission unit" or make a modification to a "stationary source" in an area that is covered by a maintenance plan, shall result in the issuance of an air discharge permit or other regulatory order, which contains such conditions as are reasonably necessary to assure the maintenance of compliance with this section. "New sources", new "emission units" or modifications within a designated maintenance plan area, including "stationary sources" that emit VOC or NO_x in a designated ozone maintenance plan area, shall meet the following requirements:

     (1) Emission standards. The proposed "new source" or modification shall:

     (a) Comply with all applicable New Source Performance Standards, National Emission Standards for Hazardous Air Pollutants, National Emission Standards for Hazardous Air Pollutants for Source Categories, emission standards adopted under Chapter 70.94 RCW, and the applicable emission standards of the Agency; and

     (b) Not cause any ambient air quality standard as provided in SWCAA 400-113(3) to be violated; and

     (c) Not violate the requirements for reasonable further progress established by the Washington State Implementation Plan; and

     (d) Minimize emissions to the extent that the "new source" or modification will not delay the attainment date for a nonattainment area, exceed emission levels or other requirements provided in a maintenance plan for an area that was previously identified as a nonattainment area, nor cause or contribute to a violation of any ambient air quality standard.

     (2) Control Technology Requirements - BACT/LAER. Except as provided ((in subsection (7) of this section)) below, the owner or operator of the proposed "new source", "emission unit" or modification shall apply BACT for each pollutant. In the case of a modification, the requirement for BACT shall apply to each new or modified emission unit which increases emissions. For phased construction projects, the determination of BACT shall be reviewed at the latest reasonable time prior to commencement of construction of each independent phase. If a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard has occurred, the Agency may require the application of LAER for the maintenance pollutant(s) and any pollutant for which the proposed "new source" or modification is major.

     (3) Source compliance. The owner or operator of the proposed "new source", "emission unit" or modification shall certify that all "stationary sources" owned or operated by such person (or by an entity controlling, controlled by, or under common control with such person) in Washington are in compliance or on a schedule for compliance, with all applicable emission limitations and standards under the Washington Clean Air Act Chapter 70.94 RCW).

     (4) Alternative analysis.

     (a) Except as provided in subsection (c) of this section, the owner or operator of a proposed "major stationary source" or "major modification" shall conduct an alternatives analysis;

     (b) This analysis shall include an evaluation of alternative sites, sizes, production processes, and environmental control techniques for such proposed "stationary source" or modification that demonstrates that benefits of the proposed "stationary source" or modification significantly outweigh the environmental and social costs imposed as a result of its location, construction or modification;

     (c) This analysis shall not be required for a "major stationary source" or "major modification" that is subject to this rule due to emissions of particulate matter in a designated TSP maintenance area.

     (((4) Offsets or growth allowance. The owner or operator of a proposed new "major stationary source" or "major modification" shall provide offsets as specified in subsection (8) of this section. Except as provided in subsection (7) of this section, the requirements of this section may be met in whole or in part in an ozone maintenance plan area with an allocation by SWCAA from a growth allowance, if available, in accordance with subsection (8) of this section and the applicable maintenance plan in the SIP adopted by the Board and approved by EPA.

     (5) Net air quality benefit. For cases in which emission reduction or offsets are required in accordance with subsection (4) above, the applicant shall demonstrate that a net air quality benefit will be achieved in the maintenance plan area. If the proposed "new source" or modification is major for the contaminant for which the area has a maintenance plan, allowable emissions of the maintenance pollutant from the proposed "new source" or modification shall be offset by reductions in actual emissions of the maintenance pollutant. All offsetting emission reductions must satisfy the requirements of subsection (8).

     (6) Alternative analysis.

     (a) Except as provided in subsection (6)(c) of this section, the owner or operator of a proposed "major stationary source" or "major modification" shall conduct an alternatives analysis;

     (b) This analysis shall include an evaluation of alternative sites, sizes, production processes, and environmental control techniques for such proposed "stationary source" or modification that demonstrates that benefits of the proposed "stationary source" or modification significantly outweigh the environmental and social costs imposed as a result of its location, construction or modification;

     (c) This analysis shall not be required for a "major stationary source" or "major modification" that is subject to this rule due to emissions of particulate matter in a designated TSP maintenance area.

     (7) Contingency plan requirements. If the contingency plan in an applicable maintenance plan (CO or ozone) has been triggered due to a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard, this section shall apply in addition to other requirements of this rule and the applicable approved maintenance plan adopted by the Board and approved by EPA as a revision to the SIP.

     (a) A proposed "major stationary source" or "major modification," must achieve LAER for the maintenance pollutant(s) and any pollutant for which the proposed "new source" or modification is major.

     (b) An allocation from a growth allowance shall not be used to meet the requirement for offsets in subsection (4) of this section. The growth allowance emissions shall be unavailable until a sufficient demonstration is made to reinstate the growth allowance emissions, the Board adopts a revised maintenance plan, and EPA approves it as a SIP revision.))

     (((8))) (5) Emission offsets and industrial growth allowances ((and offset allocation)). The owner or operator of a proposed new "major stationary source" or "major modification" shall provide emission offsets that satisfy the requirements of this section. Except as provided in subsection (a) of this section, the offset requirements of this section may be met in whole, or in part, by an allocation from an industrial growth allowance, if available.

     (((a))) Industrial growth allowances for "stationary sources" in a maintenance plan area are identified in and governed by the Washington SIP and the maintenance plan for the applicable maintenance plan area. All growth allowance allocations for the maintenance plan areas within the Agency's jurisdiction shall be made in accordance with this section.

     (((b))) (a) ((The)) Available growth allowances ((emissions)) may be increased or decreased as provided in a revision to the maintenance plan submitted to and approved by EPA. ((In the event of a confirmed ozone violation, the growth allowance for VOC and NO_x emissions shall be eliminated and "new sources" shall be required to implement LAER and offsets. Growth allowance emissions may be reinstated as provided in the EPA approved maintenance plan.)) If a violation of an ozone ambient air quality standard or a second violation of the CO ambient air quality standard has occurred, the Agency may suspend the use of growth allowances, and require the proposed new "major stationary source" or "major modification" to provide offsets as described in subsection (c) below.

     (((c))) (b) The owner or operator of a proposed new "major stationary source" or "major modification" emitting VOCs, ((or)) NO_x, or CO may obtain a portion of any remaining emissions in the respective growth allowance in accordance with the following process:

     (i) Access is on a first-come-first-served basis, based on the date of a complete application and allowance allocation request;

     (ii) Growth allowances shall be used to satisfy offset requirements at a ratio of 1 to 1 for new VOC and/or NO_x emissions.

     (iii) No single "stationary source" may receive an emissions allocation of more than 50 percent of ((any remaining)) the available growth allowance, or up to 10.0 tons per year, whichever is greater. On a case-by-case basis, the SWCAA Board of Directors may approve an emissions allocation of greater than 50 percent upon consideration of the following:

     (A) Information submitted by the "stationary source" to SWCAA justifying its request for exceeding the 50 percent emissions allocation, based on significant economic, employment, or other benefits to the maintenance plan area that will result from the proposed new "major stationary source" or "major modification";

     (B) Information provided by SWCAA on other known new "major stationary sources" or "major modifications" seeking an emissions allocation from the same growth allowance; and

     (C) Other relevant information submitted by the "stationary source" or SWCAA.

     (((iii))) (iv) To avoid jeopardizing maintenance of the ozone standard during the interim years of the ozone maintenance plan, SWCAA ((shall allocate only a portion of)) may limit the quantity of VOC and NO_x growth allowances made available each year. SWCAA will track use of VOC and NO_x allocations from the growth allowances. ((The amount of the growth allowance that can be allocated each year is identified in the applicable ozone maintenance plan.))

     (((iv))) (v) The amount of the CO growth allowance that can be allocated is identified in the applicable CO maintenance plan, if any.

     (((d))) (c) If no emissions remain in the respective growth allowance, or the ((contingency plan has been triggered which effectively zeros the)) Agency has suspended the use of growth allowances, the owner or operator of the proposed "major stationary source" or "major modification" shall provide offsets.

     (i) A demonstration shall be provided showing that the proposed offsets will improve air quality in the same geographical area affected by the "new source" or modification. This demonstration may require that air quality modeling be conducted according to the procedures specified in 40 CFR Part 51, Appendix W, Guideline on Air Quality Models (Revised).

     (ii) Offsets for VOCs or nitrogen oxides shall be within the same maintenance plan area as the proposed "stationary source." Offsets for particulate matter, PM₁₀, sulfur dioxide, carbon monoxide, nitrogen dioxide, lead, and other pollutants may be from inside or outside of the same maintenance plan area.

     (iii) "New sources" or modifications shall meet the following offset requirements:

     (A) Within a designated maintenance plan area, the offsets shall provide reductions that are equivalent or greater than the proposed increases. The offsets shall be appropriate in terms of short term, seasonal, and yearly time periods to mitigate the impacts of the proposed emissions;

     (B) Outside a designated maintenance plan area, owners or operators of "new sources" or modifications which have a significant air quality impact on the maintenance plan area as provided in SWCAA 400-113(3) shall provide emission offsets which are sufficient to reduce impacts to levels below the significant air quality impact level within the maintenance plan area; and

     (C) The emission reductions must provide for a net air quality benefit.

     (I) New "major stationary sources" within an ozone maintenance plan area shall:

     (a) Offset the new VOC emissions at a ratio of 1.1 to 1, if the VOC emissions exceed either 100 tons per year or 700 pounds per day.

     (b) Offset the new NO_x emissions at a ratio of 1.1 to 1, if the NO_x emissions exceed either 100 tons per year or 700 pounds per day.

     (II) "Stationary sources" within an ozone maintenance plan area undergoing "major modifications" shall:

     (a) Offset the entire VOC emissions increase at a ratio of 1.1 to 1, if such increase exceeds either 40 tons per year or 290 pounds per day.

     (b) Offset the entire NO_x emissions increase at a ratio of 1.1 to 1, if such increase exceeds either 40 tons per year or 290 pounds per day.

     (III) New "major stationary sources" within a carbon monoxide maintenance plan area shall:

     (a) Offset the new carbon monoxide emissions at a ratio of 1 to 1, if the carbon monoxide emissions exceed either 100 tons per year or 700 pounds per day.

     (IV) "Stationary sources" within a carbon monoxide maintenance plan area undergoing "major modifications" shall:

     (a) Offset the entire carbon monoxide emissions increase at a ratio of 1 to 1, if such increase exceeds either 100 tons per year or 700 pounds per day.

     (((D) New "major stationary sources" or "major modifications" with CO emissions greater than 250 tons per year are required to obtain offsets.))

     (iv) Emission reductions shall be of the same type of pollutant as the emissions from the "new source" or modification. Sources of PM₁₀ shall be offset with particulate in the same size range.

     (v) Emission reductions shall be contemporaneous, that is, the reductions shall take effect prior to the time of startup but not more than two years prior to the submittal of a complete application for the "new source" or modification. This time limitation may be extended through banking, as provided in SWCAA 400-130, 400-131 and 400-136 for banking activities approved after the effective date of this regulation. In the case of replacement facilities, SWCAA may allow simultaneous operation of the old and new facilities during the startup period of the new facility provided that emissions do not exceed the new emission limits.

     (vi) Offsets for new "major stationary sources" or "major modifications" in a maintenance plan area shall meet the following requirements:

     (A) The proposed new level of allowable emissions of the "stationary source" or emission unit providing the reduction must be less than the current level of actual emissions of that "stationary source" or emission unit. No emission reduction can be credited for actual emissions that exceed the current allowable emissions of the "stationary source" or emission unit providing the reduction. Emission reductions imposed by local, state, or federal regulations, regulatory orders or permits cannot be credited.

     (B) If the offsets are provided by another "stationary source," the reductions in emissions from that "stationary source" must be federally enforceable by the time the new or modified "stationary source" commences operation. The "new source" may not commence operation before the date such reductions are actually achieved. SWCAA may allow simultaneous operation of the old and new facilities during the startup period of the new facility provided that the facilitywide emissions do not exceed the new emission limit.

     (9) PSD applicability. If the proposed "new source" is a "major stationary source" or the proposed modification is a "major modification" for the purposes of the PSD program as described in WAC 173-400-((141))700 through 173-400-750, the "new source" or modification shall meet the requirements of that program for all pollutants. For maintenance plan pollutants, the "new source" shall meet all PSD requirements in addition to the requirements of this section.

     (10) Toxics. If the proposed "new source" or modification will emit any toxic air pollutants regulated under Chapter 173-460 WAC, the "new source" shall meet all applicable requirements of that regulation.

     (11) Visibility. If the proposed "new source" is a "major stationary source" or the proposed modification is a "major modification," the "new source" shall meet all the visibility protection requirements of WAC 173-400-117.

     (12) Noncompliance. 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.

     (1) The prevention of significant deterioration or PSD program is a construction permitting program for new major stationary sources and major modifications to existing major stationary sources located in areas in attainment or in areas that are unclassifiable for any criteria air pollutant. No major stationary source or major modification to which the requirements of this section apply shall begin actual construction without a PSD permit.

     (2) Early planning encouraged. In order to develop an appropriate application, the source should engage in an early planning process to assess the needs of the facility. An opportunity for a preapplication meeting with ecology is available when ecology is the permitting agency.

     (3) Application.

     (a) The PSD application is a form of a notice of construction application and the PSD permit is a form of an approval order.

     (b) The applicant shall provide complete copies of its PSD application, distributed in the following manner:

     (i) Three copies shall be sent to the permitting agency. If ecology is the permitting agency, copies must be sent to the Air Quality Program at P.O. Box 47600, Olympia, WA 98504-7600.

     (ii) One copy shall be sent to each of the following federal land managers:

     (A) U.S. Department of the Interior - National Park Service; and

     (B) U.S. Department of Agriculture - U.S. Forest Service.

AMENDATORY SECTION (Amending WSR 01-05-057, filed 2/15/01, effective 3/18/01)

SWCAA 400-200 Vertical Dispersion Requirement, Creditable Stack Height and Dispersion Techniques

[Statutory Authority: Chapter 70.94.141 RCW. Original Board adoption 400-160 4/17/84 (Refer to WAC 403); Amended by Board 92-04-030 filed 1/28/92; Amended by Board and renumbered to 400-200 in 93-21-005 filed 10/7/93, effective 11/8/93, original 400-200 was renumbered to 400-230; 95-17-084 filed 8/21/95, effective 9/21/95; 01-05-057 filed 2/15/01, effective 3/18/01]

     (1) Vertical Dispersion Requirement. All new exhaust stacks shall be configured to discharge vertically to the ambient atmosphere. Stack devices, such as rain caps, that obstruct or prevent vertical discharge are prohibited. Where possible, exhaust stacks shall discharge at a point higher than surrounding buildings and/or terrain. Alternate exhaust stack configurations may be approved by SWCAA on a case-by-case basis.

     (((1))) (2) Creditable Stack Height and Dispersion Techniques - Applicability. The((se)) provisions ((shall apply)) of subsections (3) and (4) of this section are applicable 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 modifications were carried out after December 31, 1970;

     (b) Coal-fired steam electric generating units subject to the provisions of Section 118 of the Federal Clean Air Act, which commenced operation before July 1, 1957, and for whose stacks construction commenced before February 8, 1974;

     (c) Flares;

     (d) Open or outdoor burning for agricultural or silvicultural purposes as covered under the Smoke Management Plan;

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

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

     (((2))) (3) Creditable Stack Height and Dispersion Techniques - Prohibitions. No source may use dispersion techniques or excess stack height to meet ambient air quality standards or PSD increment limitations.

     (a) Excess stack height. Excess stack height is that portion of a stack that exceeds the greater of:

     (i) Sixty-five meters (213.25 feet), measured from the ground level 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,

     L = lesser dimension, height or projected width, of nearby structure(s), subject to the provisions below.

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

     (b) Dispersion techniques. Increasing final exhaust 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 gas plume rise. This does not include:

     (i) The reheating of a gas stream, following the use of a pollution control system, for the purpose of returning the gas to the temperature at which it was originally discharged from the facility generating the gas stream;

     (ii) The merging of gas streams where:

     (A) The source was originally designed and constructed 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 pollutant 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 emissions control equipment or was carried out for sound economic or engineering reasons, and not primarily motivated by an intent to gain emissions credit for greater dispersion.

     (((3))) (4) Creditable Stack Height - Exception. The Agency may require the use of a field study or fluid model to verify the creditable stack height for the source. This also applies to a source seeking credit after the effective date of this rule for an increase in existing stack height up to that established by the GEP formula. A fluid model or field study shall 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 Regulations). 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 pollutant as a result of atmospheric downwash, wakes, or eddy effects created by the source itself, nearby structures or nearby terrain features.

     (a) "Nearby," as used in this subsection for conducting a field study or fluid model, means 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 times 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 twenty-six meters, whichever is greater, as measured from the ground-level elevation at the base of the stack. The height of the structure or terrain feature is measured from the ground-level elevation at the base of the stack.

     (b) "Excessive concentration" is defined for the purpose of determining creditable stack height under this subsection and means a maximum ground-level concentration owing to a significant downwash effect which contributes to excursion over an ambient air quality standard. For sources subject to PSD review (WAC 173-400-((141))720 and 40 CFR 52.21) an excessive concentration alternatively means a maximum ground-level concentration owing to a significant downwash effect that 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 ground-level concentration due to emissions from a stack due in whole or in part to downwash, wakes, and eddy effects produced by nearby structures or nearby terrain features which individually is at least forty percent in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects.
