AMENDATORY SECTION (Amending WSR 20-06-003 filed 2/19/20, effective 3/21/20)

Federal rules cited in this rule are adopted by reference as in effect on ((July 1, 2019)) May 1, 2021.

AMENDATORY SECTION (Amending WSR16-19-009 filed 9/8/16, effective 10/9/16)

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. For the purposes of regulation under the Washington SIP, "air contaminant" means only:

(a) Those air contaminants for which EPA has established National Ambient Air Quality Standards (NAAQS) and precursors to such NAAQS pollutants as determined by EPA for the applicable geographic area; and

(b) Any additional air contaminants that are required to be regulated under Part C of Title I of the Federal Clean Air Act, but only for the purpose of meeting the requirements of Part C or to the extent those additional air contaminants are regulated in order to avoid such requirements.

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

(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, 62, 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)) 70A.15 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 Parts 60, 61, 62 and 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.

(18) "Bubble" means a set of emission limits which allows an increase in emissions from a given "emission unit" in exchange for a decrease in emissions from another "emission unit", pursuant to RCW ((70.94.155)) 70A.15.2240 and SWCAA 400-120.

If the owner or operator of such a portable source does not wish to utilize the provisions of this section, an air discharge permit application must be filed for the portable source pursuant to SWCAA 400-109. Portable sources that have a valid air discharge permit issued by SWCAA must operate in accordance with the SWCAA permit, and may not use the provisions of this section. This section does not apply to nonroad engines of any type.

(2) Nonattainment areas. If a portable source is locating in a nonattainment area and emits the pollutant(s) or pollutant precursors for which the area is classified as nonattainment, the source must acquire a site-specific air discharge permit from SWCAA.

(3) Major Stationary Source. If a portable source is a major stationary source then the source must also comply with applicable requirements from WAC 173-400-700 through 173-400-750.

(4) General Requirements. Portable sources must comply with the requirements listed below in order to gain coverage under this section.

(a) The portable source must possess a valid approval issued by a Washington air pollution control authority after July 1, 2010. The approval must identify the affected "emission units" as a portable source.

(b) Approval for the portable source must contain emission limitations and operational requirements that are consistent with BACT as determined by SWCAA for similar sources.

(c) The owner/operator of the portable source must pay a review fee as provided in the current Consolidated Fee Schedule established in accordance with SWCAA 400-098.

(d) The owner/operator must obtain written confirmation from SWCAA that the portable source complies with the provisions of this section prior to commencing operation within SWCAA jurisdiction.

(e) The owner/operator of the portable source must submit a relocation notice and a copy of the applicable order of approval or air discharge permit to SWCAA at least 15 calendar days prior to commencing operation within SWCAA jurisdiction. An additional relocation notice shall be submitted for each subsequent location at which the source operates, including departure from SWCAA's jurisdiction.

(f) The owner/operator shall register the portable source with SWCAA and pay a registration fee as provided in the current Consolidated Fee Schedule established in accordance with SWCAA 400-098 ((prior to commencement of operation)) concurrent with submission of the relocation notice cited in section (e). For the purposes of this registration, ((the term)) each"emission unit" ((means each rock crusher and aggregate screen and associated haul roads)) shall be registered. Registration expires at the end of the Agency's fiscal year. If a permitted unit is still operating after its registration expires, it shall be reregistered including payment of the annual registration fee.

(g) The owner/operator must submit an emission inventory report to SWCAA as described in SWCCA 400-105(1). The inventory report must contain information sufficient to enable calculation of air emissions from operation of the portable source within SWCAA jurisdiction. If the portable source operated at multiple locations, the inventory report must identify emissions specific to each location.

(5) Enforcement of approval conditions. SWCAA will enforce all terms and conditions contained in the portable source's order of approval or air discharge permit, regardless of which permitting authority approved the portable source.

(6) Modification of approval conditions. Terms and conditions contained in the portable source's order of approval or air discharge permit may only be modified by obtaining a new air discharge permit from SWCAA.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

All "sources" and "emission units" are required to meet the emission standards of this section. Where an emission standard listed in another section is applicable to a specific "emission unit", such standard shall take precedent over a general emission standard listed in this section. When two or more "emission units" are connected to a common stack and the operator elects not to provide the means or facilities to sample emissions from the individual "emission units", and the relative contributions of the individual "emission 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 "emission units".

All "emission units" are required to use reasonably available control technology (RACT) that may be determined for some "stationary 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 Agency shall, as provided in RCW ((70.94.154)) 70A.15.2230, define RACT for each "stationary 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)) allow the emission for more than three minutes, in any one hour, of an air contaminant which at the emission point, or within a reasonable distance of the emission point, exceeds twenty percent opacity as determined in accordance with SWCAA Method 9, Ecology Method 9A or 9A-Alternate 1 (LIDAR) except as follows:

(a) Soot blowing/grate cleaning. When ((the)) emissions occur due to soot blowing/grate cleaning ((and the operator can demonstrate that the emissions will)) of a hog fuel or wood-fired boiler, visible emissions shall not exceed ((twenty)) forty 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. Except for testing and troubleshooting, soot blowing/grate cleaning is to be scheduled for the same approximate times each day. The boiler operator shall maintain a written schedule on file with the Agency and provide updates as necessary.

(b) When the owner or operator of an "emission unit" supplies valid data to show that the presence of uncombined water is the only reason for the opacity to exceed twenty percent or an alternative opacity standard established in this section.

(c) When two or more "emission units" are connected to a common stack, the Agency 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))) 70A.15.3000 (2)(c).

(e) Alternative Standard for Boiler Startup or Shutdown. Hog fuel or wood-fired boiler in operation before January 24, 2018. For emissions that occur due to planned startup or shutdown of a hog fuel or wood-fired boiler with dry particulate matter controls, an owner or operator may use the alternative standard in this subsection when all of the requirements below are met.

(((e))) (g) ((Exemptions from the twenty percent opacity standard.))

(((i))) Military training. Visible emissions resulting from military obscurant training exercises ((is)) are exempt from compliance with the twenty percent opacity limitation provided the following criteria are met:

(((A))) (i) No visible emissions shall cross the boundary of the military training site/reservation.

(((B))) (ii) The operation shall have in place methods, which have been reviewed and approved by the permitting agency, to detect changes in weather that would cause the obscurant to cross the site boundary either during the course of the exercise or prior to the start of the exercise. The approved methods shall include provisions that cancel the training exercise or cease the use of obscurant during the training exercise until weather conditions would allow such training to occur without causing obscurant to leave the site boundary of the military site/reservation.

(((ii))) (h) Certification testing. Visible emissions from the "smoke generator" used for testing and certification of visible emissions readers per the requirements of 40 CFR 60, Appendix A, Reference Method 9 and Ecology Methods 9A and 9B shall be exempt from compliance with the twenty percent opacity limitation while being used for certifying visible emission readers.

(((iii))) (i) Firefighter training. Visible emissions from fixed and mobile firefighter training facilities are exempt while being used to train firefighters and while complying with the requirements of WAC 173-425.

(2) Fallout. No person shall cause or permit the emission of particulate matter from any "stationary source" to be deposited beyond the property under direct control of the owner or operator of the "stationary 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 "emission unit" engaging in materials handling, construction, demolition or any other operation that emits fugitive emissions:

(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 "emission 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 air contaminants for which nonattainment has been designated.

(4) Odors.

(a) No person shall cause or allow the generation of any odor from any "source" or activity, which may unreasonably interfere with any other property owner's use and enjoyment of his property. ((Recognized good practice and procedures must be used to reduce odors to a reasonable minimum.)) The Agency may take enforcement action under this section if it documents the following:

(i) The detection by the Executive Director or a duly authorized representative of an odor at Level 3 or greater, according to the following odor scale:

Level 0 No odor detected,

Level 1 Odor barely detected,

Level 2 Odor is distinct and definite, any unpleasant characteristics recognizable,

Level 3 Odor is objectionable enough or strong enough to cause attempts at avoidance, and

Level 4 Odor is so strong that a person does not want to remain present; and

(ii) An affidavit from a person making a complaint that demonstrates that they have experienced odor emissions in sufficient quantities and of such characteristics and duration so as to unreasonably interfere with their enjoyment of life and property.

(b) When the "source" is using "good agricultural practices," as provided in RCW ((70.94.640)) 70A.15.4530, 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 "emission unit" in excess of one thousand ppm of sulfur dioxide on a dry basis, corrected to seven percent oxygen or twelve percent carbon dioxide as required by the applicable emission standard for combustion sources, and based on the average of any period of sixty consecutive minutes.

(7) Concealment and masking. No person shall cause or permit the installation or use of any means that 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 any "source" of or activity that generates 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 "stationary source(s)" of fugitive dust that has been identified as a significant contributor to a PM10 or PM2.5 nonattainment area shall be required to use reasonably available control technology (RACT) to control emissions. The status of a "stationary source" as a significant contributor will be determined by the criteria found in SWCAA 400-113(3).

AMENDATORY SECTION (Amending WSR 17-11-078 filed 5/18/17, effective 6/18/17)

The registration program is intended to develop and maintain a current and accurate record of air contaminant sources. Information collected through the registration program is used to evaluate the effectiveness of air pollution control strategies and to verify "source" compliance with applicable air pollution requirements.

(1) Applicability. All "sources" or "emission units" shall be registered with the Agency in accordance with this section as set forth in RCW ((70.94.151)) 70A.15.2200. A "source" or "emission unit" is subject to registration from the time it is approved by the Agency until the time at which it permanently ceases operation. "Emission units" that are part of a portable stationary source must register upon initiation of operation within the Agency's jurisdiction and every year thereafter.

(a) Registration requirements are not applicable to the following:

(a)(i)"Emission units" or activities exempted under SWCAA 400-101; and

(b)(ii) "Stationary sources" required to apply for, or to maintain, an operating permit under Chapter 173-401 WAC.

(b) Regardless of the exemptions provided above, the following "sources" must be registered with the Agency:

(i) Gasoline stations with an annual throughput of 200,000 gallons or more (highest annual throughput in last 3 calendar years) and

(ii) ((all)) Dry cleaners with VOC or TAP emissions ((shall be registered)).

(2) General requirements.

(a) The owner or operator of a "source" for which registration is required shall initially register affected "emission units" with the Agency. A unique identification number shall be assigned to each "source" and a separate registration fee shall be provided for each "emission unit"; provided that, an owner may request to register a process with a detailed inventory of air contaminant sources and emissions related to the process as a single unit. A registration fee shall not be collected for exempt "emission units" identified in SWCAA 400-101.

(b) The owner or operator of a registered "source" shall submit annual reports to the Agency. Each report shall contain information as may be required by the Agency concerning location, size and height of contaminant outlets, processes employed, nature and quantity of the air contaminant emission and such other information as is relevant to air pollution and available or reasonably capable of being assembled. Relevant information may include air pollution requirements established by rule, regulatory order, air discharge permit or ordinance pursuant to Chapter ((70.94)) 70A.15 RCW. The owner, operator, or their designated representative shall sign the annual report for each "source," and be responsible for the accuracy, completeness, and timely submittal of all required information.

(3) Registration fees. An annual registration fee shall be paid before the Agency may register any "emission unit". Annual registration fees are based on the number of registered "emission units" and the quantity of "source" emissions during the previous calendar year. Collected registration fees are used by the Agency in the next fiscal year (July 1 through June 30). "Sources" or "emission units" that permanently shutdown prior to January 1 of the current registration period shall not be liable for registration fees. This provision does not apply to "temporary sources" or portable sources. Operation of equipment subject to registration without payment of applicable registration fees shall be considered a violation of this section. Annual registration fees shall be paid according to the current Consolidated Fee Schedule established in accordance with SWCAA 400-098.

Exceptions:

(a) An annual registration fee shall be charged to each gasoline transport tank as provided in the current Consolidated Fee Schedule established in accordance with SWCAA 400-098.

Such fees shall be used exclusively to support and administer the operating permit program. The purpose of the program reserve fund is to ensure that permit program costs are not funded by fees from "stationary sources" not participating in the operating permit program. The value of monies held in the program reserve fund shall not exceed 15 percent of the average permit program budget over the most recent three-year period.

(b) The Agency shall keep a record of all reasonable (direct and indirect) costs to develop and administer the Operating Permit Program as specified in 40 CFR Part 70. This information shall be used by the Agency to develop the Operating Permit Program budget specified in section (3) above. The information obtained from tracking revenues, time and expenditures shall not provide a basis for challenge to the amount of an individual "stationary source's" fee.

(c) In the event that the assessed fees exceed the cost of developing and administering the Operating Permit Program, including the program reserve fund, such excess fees shall be used to develop and administer the Operating Permit Program in the next subsequent year. The amount of the excess fees shall be deducted from the projected budget of the next subsequent year prior to fee assessment for the subsequent year.

(6) Fee eligible activities.

(a) Preapplication assistance and review of an application and proposed compliance plan for a permit, permit revision or permit renewal;

(b) Inspections, testing and other data gathering activities necessary for development of a permit, permit revision or renewal;

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

(1) Excess emission recordkeeping and reporting. Excess emissions shall be reported to SWCAA as follows:

(a) Excess emissions that represent a potential threat to human health or safety shall be reported as soon as possible, but no later than 12 hours after discovery.

(b) Excess emissions which the owner or operator wishes to be considered as unavoidable, shall be reported to the Agency as soon as possible, but no later than 48 hours after discovery.

(c) All other excess emissions shall be reported within 30 calendar days after the end of the month during which the event is discovered, or for Air Operating Permit sources, as provided in WAC 173-401-615(3).

(d) Excess emission reports shall contain the following information:

(i) Identification of the "emission unit(s)" involved;

(ii) A brief description of the event including identification of known causes;

(iii) Date, time and duration of the event;

(v) Corrective action taken in response to the event; and

(vi) Preventive measures taken or planned to minimize future recurrence.

(e) For any excess emissions the owner or operator wishes to be considered as unavoidable, the excess emission report must include the following information in addition to that listed in subsection (d) above:

(i) Properly signed, contemporaneous records documenting the owner or operator's actions in response to the excess emissions event;

(ii) Information on whether installed emissions monitoring and pollution control systems were operating at the time of the exceedance. If either or both systems were not operating, information on the cause and duration of the outage; and

(iii) All additional information required by section (2) below supporting the claim that the excess emissions were unavoidable.

(2) Unavoidable excess emissions. Excess emissions determined to be unavoidable under the procedures and criteria in this section are violations of the applicable statute, rule, permit or regulatory order. ((Unavoidable excess emissions are subject to injunctive relief but not penalty.)) The decision that excess emissions are unavoidable is made by the permitting authority. Excess emissions determined by the permitting authority to be unavoidable are a violation subject to SWCAA 400-230 (3), (4) and (6), but not subject to civil penalty under SWCAA 400-230(2). In a federal enforcement action filed under 42 USC 7413 or 7604 the decision-making authority shall determine what weight, if any, to assign to the permitting authority's determination that an excess emissions event does or does not qualify as unavoidable under the criteria in subsections (c)((,)) and (d)((, and (e))) below.

(a) Burden of proof. The owner or operator of a "source" shall have the burden of proving to the Agency or decision-making authority in an enforcement action that excess emissions were unavoidable. This demonstration shall be a condition to obtaining relief under this section.

(b) Applicability. This section does not apply to excess emissions that:

(i) Cause a monitored exceedance of any relevant ambient air quality standard;

(ii) Exceed emission standards promulgated under 40 CFR Parts 60, 61, 62, 63, 72, or a permitting authority's adoption by reference of such federal standards; and

(iii) Exceed emission limits and standards contained in a PSD permit issued solely by EPA.

(c) Startup or shutdown. Excess emissions due to an upset or malfunction during a startup or shutdown event shall be treated as an upset or malfunction under subsection (d) of this section. ((conditions shall be considered unavoidable provided the "source" reports as required under section (1) and adequately demonstrates that:

(d) Maintenance. Excess emissions due to scheduled maintenance shall be considered unavoidable if the "source" reports as required under section (1) and adequately demonstrates that the excess emissions could not have been avoided through reasonable design, better scheduling for maintenance or through better operation and maintenance practices.))

(((e))) (d) Upsets or malfunctions. Excess emissions due to upsets or equipment malfunctions shall be considered unavoidable provided the "source" reports as required under section (1) and adequately demonstrates that:

(i) The event was not caused by poor or inadequate design, operation, maintenance, or any other reasonably preventable condition;

(ii) The event was not of a recurring pattern indicative of inadequate design, operation, or maintenance;

(iii) The operator took immediate and appropriate corrective action in a manner consistent with safety and good air pollution control practice for minimizing emissions during the event, taking into account the total emissions impact of the corrective action, including slowing or shutting down the "emission unit" as necessary to minimize emissions, when the operator knew or should have known that an emission standard or permit condition was being exceeded;

(((iv)))(v) All emission monitoring systems and pollution control systems were kept operating to the extent possible unless their shutdown was necessary to prevent loss of life, personal injury, or severe property damage; ((and))

(((v)))(vi) The amount and duration of the excess emissions (including any bypass) were minimized to the maximum extent possible; and

AMENDATORY SECTION (Amending WSR 17-11-078 filed 5/18/17, effective 6/18/17)

(1) Purpose.

The request shall clearly identify the justification for an extension and include relevant supporting information)) complete application as described in SWCAA 400-109 (2)(f). The Agency will review all submitted information, and then approve or deny the ((request)) extension in writing. If the original permit action required a public comment period pursuant to SWCAA 400-171, the Agency shall provide an additional public comment period prior to approving an extension. An extension for a PSD permit must be approved by Ecology. The extension of a project that is either a major stationary source or a major modification, as those terms are defined in SWCAA 400-810, shall also require determination of LAER as it exists at the time of the extension for the pollutants that were subject to LAER in the original approval.

(10) Revocation. The Agency may revoke a source's Order of Approval or air discharge permit if applicable registration fees are delinquent for 2 or more consecutive years.

(((9))) (11) Change of conditions.

(a) The owner or operator may request, at any time, a change in existing approval/permit conditions. The Agency may approve the request provided that:

(i) The change will not cause an applicable emissions standard set by regulation or rule to be exceeded;

(ii) No ambient air quality standard or ambient air increment will be exceeded as a result of the change;

(iii) The change will not adversely impact the ability of the Agency to determine compliance with an emissions standard;

(iv) The revised approval conditions will continue to require BACT, as defined at the time of the original approval, for each approved "stationary source"except where the Federal Clean Air Act requires LAER (e.g., any change that meets the definition of a "new source" must complete a new BACT determination); and

(v) The revised approval conditions meet the requirements of SWCAA 400-110, 400-111, 400-112, 400-113, and 400-830(3) as applicable.

(b) Requests for a change in PSD permit conditions must be made directly to Ecology. The Agency does not have authority to issue or modify PSD permits.

(c) Actions taken under this subsection are subject to the public involvement provisions of SWCAA 400-171 as applicable.

(d) The criteria in 40 CFR 52.21 (r)(4), as adopted by reference in WAC 173-400-720 or SWCAA 400-830(3) as applicable, shall be considered when determining which new source review approvals are required.

(e) A request to change approval/permit conditions shall be filed as an air discharge permit application in accordance with SWCAA 400-109. The application shall meet the requirements of subsection (2) of this section, and be acted upon according to the timelines in subsections (3) and (4) of this section. The fee schedule found in SWCAA 400-109(4) shall apply to these requests.

"New sources" or modifications within a designated maintenance plan area, including "stationary sources" that emit VOC or NOx 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)) 70A.15 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 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)) 70A.15 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.

(5) Emission offsets and industrial growth allowances. 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. 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.

(a) Available growth allowances may be increased or decreased as provided in a revision to the maintenance plan submitted to and approved by EPA. 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.

(b) The owner or operator of a proposed new "major stationary source" or "major modification" emitting VOCs, NOx, 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 NOx emissions.

(iii) No single "stationary source" may receive an emissions allocation of more than 50 percent of 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.

(iv) To avoid jeopardizing maintenance of the ozone standard during the interim years of the ozone maintenance plan, SWCAA may limit the quantity of VOC and NOx growth allowances made available each year. SWCAA will track use of VOC and NOx allocations from the growth allowances.

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

(c) If no emissions remain in the respective growth allowance, or 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 (as in effect on the date cited in SWCAA 400-025).

(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 NOx emissions at a ratio of 1.1 to 1, if the NOx 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 NOx 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.

(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.

(6) 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 173-400-700 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.

(7) Toxics. If the proposed "new source" or modification will emit any toxic air pollutants regulated under Chapter 173-460 WAC (as in effect 8/21/98), the "new source" shall meet all applicable requirements of that regulation.

(8) 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.

(9) 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.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

"New sources" or modifications within a designated nonattainment area shall meet the following requirements:

(1) Emission standards. The proposed "new source" or modification will 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)) 70A.15 RCW and the applicable emission standards of the Agency.

(2) Control technology requirement. The proposed "new source" or modification will employ BACT for all air contaminants not subject to LAER that the "new source" will emit or for which the modification will cause an emissions increase. If the "new source" is a "major stationary source" or the proposed modification is a "major modification" it will achieve LAER for the air contaminants for which the area has been designated nonattainment and for which the proposed "new source" is major or for which the existing source is major and the modification is significant.

(3) Ambient air quality standards. The proposed "new source" or modification will not cause any ambient air quality standard to be exceeded, will not violate the requirements for reasonable further progress established by the Washington SIP and will comply with SWCAA 400-113(3) for all air contaminants for which the area has not been designated nonattainment.

(4) 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.

(5) Major new source review. If the proposed "new source" is a "major stationary source" or the proposed modification is a "major modification" as those terms are defined in SWCAA 400-810, it shall meet the requirements of SWCAA 400-800 through 400-860.

(6) Toxics. If the proposed "new source" or modification will emit any toxic air pollutants regulated under Chapter 173-460 WAC (as in effect 8/21/98), it shall meet all applicable requirements of that chapter.

(7) Visibility. If the proposed "new source" is a "major stationary source," or the proposed modification is a "major modification," it shall meet the special protection requirements for federal Class I areas found in WAC 173-400-117.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

"New sources" or modifications in an area that is in attainment or unclassifiable shall meet the following requirements:

(1) Emission standards. The proposed "new source", "emission unit" or modification shall 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)) 70A.15 RCW and the applicable emission standards of the Agency.

(2) Control technology requirement. The proposed "new source" or modification shall employ BACT for all pollutants not previously emitted or whose emissions would increase as a result of the "new source" or modification.

(3) Allowable impact levels. Allowable emissions from the proposed "new source", "emission unit" or modification shall not delay the attainment date for an area not in attainment, nor cause or contribute to a violation of any ambient air quality standard. This requirement will be met if the projected impact of the allowable emissions from the proposed "new source" or the projected impact of the increase in allowable emissions from the proposed modification at any location within a nonattainment or maintenance plan area does not exceed the following impact levels for the pollutant(s) for which the area has been designated nonattainment or maintenance:

If the projected impact of the proposed "new source" or modification exceeds an applicable value from the table above, the owner or operator shall provide offsetting emission reductions sufficient to reduce the projected impact to below the allowable impact level. For a proposed "new source" or modification with a projected impact within a maintenance area, this offset requirement may be met in whole, or in part, by an allocation from an industrial growth allowance. Emission offsets and growth allowance allocations used to satisfy the requirements of this section shall comply with the provisions of SWCAA 400-840.

(4) PSD applicability. If the proposed "new source" is a "major stationary source" or the proposed modification is a "major modification", as those terms are defined in WAC 173-400-710, it shall meet all applicable requirements of WAC 173-400-700 through 173-400-750.

(5) Toxics. If the proposed "new source" or the proposed modification will emit any toxic air pollutants regulated under Chapter 173-460 WAC (as in effect 8/21/98), it shall meet all applicable requirements of that chapter.

(7) 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.

AMENDATORY SECTION (Amending WSR 03-21-045 filed 10/9/03, effective 11/9/03)

(1) Any person proposing to replace or substantially alter the emission control technology installed on an existing "stationary source" or "emission unit" shall file an air discharge permit application with the Agency and shall be subject to the review process of SWCAA 400-110. If the replacement or substantial alteration meets the definition of "new source" or "modification", then the "new source" emissions standards of SWCAA 400-111, 400-112 or 400-113 shall apply. If the replacement or substantial alteration does not meet the definition of "new source" or "modification", then RACT or other requirements shall apply. Replacement or substantial alteration of control technology does not include routine maintenance, repair or parts replacement.

(2) For projects not otherwise reviewable under SWCAA 400-110, the Agency may:

(a) Require that the owner or operator employ RACT and/or T-RACT for the affected "emission unit";

(((b))) (c) Prescribe reasonable operation and maintenance conditions for the control equipment; and

(((c))) (d) Prescribe other requirements authorized by Chapter ((70.94)) 70A.15 RCW.

(3) Within thirty calendar days of receipt of an air discharge permit application under this section the Agency shall either notify the applicant in writing that the application is complete or notify the applicant in writing of all additional information necessary to complete the application. Within thirty calendar days of receipt of a complete application under this section, the Agency shall either issue an air discharge permit or a proposed RACT determination for the proposed project.

(4) Construction shall not commence on a project subject to review under this section until the Agency issues a final air discharge permit or other regulatory order. However, any air discharge permit application filed under this section shall be deemed to be approved without conditions if the Agency takes no action within thirty days of receipt of a complete application. The Agency may request clarification of information submitted in support of the application after the application has been determined to be complete.

(5) An air discharge permit to replace or substantially alter emission control technology shall become invalid if construction is not commenced within eighteen months from the date of issuance, if construction is discontinued for a period of eighteen months or more, or if construction is not completed within a reasonable time. The Agency may extend the eighteen-month period upon a satisfactory demonstration that an extension is justified. This provision does not apply to the time period between construction of the approved phases of a phased construction project; each phase must commence construction within eighteen months of the projected and approved commencement date. The Agency may specify an earlier date for commencement of construction in an air discharge permit.

(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.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

(1) Applicability. The Agency shall maintain a bank for the purpose of administering emission reduction credits (ERCs) pursuant to the provisions of RCW ((70.94.850)) 70A.15.6230.

(2) Conditions for ERC bank.

(a) ERCs established under SWCAA 400-131 shall be available for said credit bank.

(b) ERCs shall not have been used, sold or transferred to another entity for use; e.g. ERCs cannot be banked or used by two "sources" at one time.

(c) ERCs established under SWCAA 400-131 or used under SWCAA 400-130 for a specific "source" shall be allocated privately and not be available for public allocation unless specifically requested by the owner(s) of the ERCs.

(3) Maintenance of the bank.

(a) The Agency shall maintain an emission inventory of all allowed and actual emissions (including any growth allowances identified in a maintenance plan) in each of the nonattainment or maintenance areas by pollutant or in the case of ozone, it shall be volatile organic compounds and oxides of nitrogen.

(b) The ERCs contained in the bank shall be discounted by 10 percent to allow for minor emission increases in nonattainment areas by minor "sources" each of which would emit less than one ton per year. Minor emitting "sources" shall be ineligible to receive or expend an emission reduction credit as identified in SWCAA 400-131 or 400-130. ERCs shall be discounted at the applicable ratio on a one-time basis at the time of deposit into the bank. ERCs shall not be discounted each time a transaction is completed. If reductions in emission beyond those identified in the Washington SIP are required to meet an ambient air quality standard, if the standard cannot be met through controls on operating "sources," and if the plan must be revised, ERCs may be discounted by the Agency over and above the initial 10 percent without compensation to the holder after public involvement pursuant to SWCAA 400-171. Any such discount shall not exceed the percentage of additional emission reduction needed to reach or maintain attainment status.

(c) The Agency shall not provide greater than 25 percent of the available emission credit in the bank to a single applicant. Any exceptions shall be considered on a case-by-case basis by the Board of Directors after a public notice at the next regularly scheduled meeting.

(d) When the Agency issues credits for a new or modified "stationary source," the amount of emission credits shall be removed from the bank and a regulatory order allocating the emission credits shall be issued. The applicant shall start a continuous program of construction or process modification within 18 months. If the applicant does not exercise the approval, the emission credit allocation shall expire and revert to the bank. If there is a six month delay in construction after the start of a continuous program to construct or modify a "stationary source" or "emission unit" the remaining amount of the emission reduction credit shall be reviewed by the Agency and if it is determined that the unused portion of the credit will not, in all likelihood be used in the next year, the Agency shall notify the applicant that the credit allocation has expired and shall revert to the bank. The applicant shall reapply, as needed, for use of the emission reduction credits when a continuous program of construction or modification begins.

(4) Annual review. The Agency shall review the content and administration of this section annually to ensure regulatory consistency and equity of impact as a portion of the Washington SIP review. The results of the review shall be reported to the Board with recommendations for correction if the Agency deems that such corrections are necessary to properly administer the emission credit bank.

(5) Issuance and use of ERCs. The Agency has established its policy and procedure for deposit of ERCs in SWCAA 400-131. The Agency has established its policy and procedure for use of ERCs in SWCAA 400-130.

(6) Expiration of public credits.

(a) Each "stationary source" which had credits assigned from the public bank by issuance of a regulatory order shall be approved for the total of previous emissions plus any additional amount approved under a regulatory order assigning public credits to that "stationary source" effective July 8, 1996.

(b) Emission reduction credits deposited into the public bank shall not be available to be assigned to any "stationary source" after July 8, 1996.

AMENDATORY SECTION (Amending WSR 03-21-045 filed 10/9/03, effective 11/9/03)

(1) The requirements of this section apply to any "existing stationary facility" as defined in SWCAA 400-030.

(2) SWCAA shall identify each "existing stationary facility" within its jurisdiction, which may reasonably be anticipated to cause or contribute to visibility impairment in any mandatory Class I federal area in Washington and any adjacent state.

(3) For each "existing stationary facility" identified under subsection (2) of this section, SWCAA shall determine Best Available Retrofit Technology (BART) for the air contaminant of concern and any additional air pollution control technologies that are to be required to reduce impairment from the "existing stationary facility."

(4) Each "existing stationary facility" shall apply BART as new technology for control of the air contaminant when it becomes reasonably available if:

(a) The "existing stationary facility" emits the air contaminant contributing to visibility impairment;

(b) Controls representing BART for that air contaminant have not previously been required under this section; and

(c) The impairment of visibility in any mandatory Class I federal area is reasonably attributable to the emissions of the air contaminant.

The Control Officer may accept an assurance of discontinuance as provided in RCW ((70.94.435)) 70A.15.3170 of any act or practice deemed in violation of this regulation as written and certified to by the "source." Any such assurance shall specify a time limit during which discontinuance or corrective action is to be accomplished. Failure to perform the terms of any such assurance shall constitute prima facie proof of a violation of its regulations 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 Superior 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 its regulations, the Control Officer, 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 injunction or another appropriate order.

(5) Emergency episodes. The Agency may issue such orders as authorized by SWCAA 435 whenever an air pollution episode forecast is declared.

(6) Compliance Orders. The Agency may issue a Compliance Order in conjunction with a Notice of Violation or when the Control Officer has reason to believe a regulation is being violated, or may be violated. The order shall require the recipient of the Notice of Violation either to take necessary corrective action or to submit a plan for corrective action and a date when such action will be initiated and completed.

AMENDATORY SECTION (Amending WSR 16-19-009 filed 9/8/16, effective 10/9/16)

The definitions in this section must be used in the major stationary source nonattainment area permitting requirements in SWCAA 400-800 through 400-860. If a term is defined differently in the federal program requirements for issuance, renewal and expiration of a Plant Wide Applicability Limit which are adopted by reference in SWCAA 400-850, then that definition is to be used for purposes of the Plant Wide Applicability Limit (PAL) program.

(1) "Actual emissions" means:

(a) The actual rate of emissions of a regulated NSR pollutant from an emissions unit, as determined in accordance with (b) through (d) of this subsection. This definition does not apply when calculating whether a significant emissions increase has occurred, or for establishing a PAL under SWCAA 400-850. Instead, "projected actual emissions" and "baseline actual emissions" as defined in subsections (24) and (2) (((and 23))) of this section apply for those purposes.

(b) In general, actual emissions as of a particular date shall equal the average rate, in tons per year, at which the unit actually emitted the pollutant during a consecutive 24 month period which precedes the particular date and which is representative of normal source operation. The permitting 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 unit's actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(c) The permitting authority may presume that source specific allowable emissions for the unit are equivalent to the actual emissions of the unit.

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

(2) "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with (a) through (d) of this subsection.

(a) For any existing electric utility steam generating unit, baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive 24 month period selected by the owner or operator within the 5 year period immediately preceding when the owner or operator begins actual construction of the project. The permitting authority shall allow the use of a different time period upon a determination that it is more representative of normal source operation.

(i) The average rate shall include emissions associated with startups, shutdowns, and malfunctions; and, for an emissions unit that is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or for an emissions unit that is located at a major stationary source that belongs to one of the listed source categories, the average rate shall include fugitive emissions (to the extent quantifiable).

(ii) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24 month period.

(iii) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24 month period must be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24 month period can be used for each regulated NSR pollutant.

(iv) The average rate shall not be based on any consecutive 24 month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by (a)(ii) of this subsection.

(b) For an existing emissions unit (other than an electric utility steam generating unit), baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive 24 month period selected by the owner or operator within the ten-year period immediately preceding either the date the owner or operator begins actual construction of the project, or the date a complete permit application is received by the permitting authority for a permit required either under SWCAA 400-800 through 400-860 or under a plan approved by the administrator, whichever is earlier, except that the 10 year period shall not include any period earlier than November 15, 1990.

(i) The average rate shall include emissions associated with startups, shutdowns, and malfunctions; and, for an emissions unit that is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or for an emissions unit that is located at a major stationary source that belongs to one of the listed source categories, the average rate shall include fugitive emissions (to the extent quantifiable).

(ii) The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive 24 month period.

(iii) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply, had such major stationary source been required to comply with such limitations during the consecutive 24 month period. However, if an emission limitation is part of a maximum achievable control technology standard that the administrator proposed or promulgated under 40 CFR Part 63, the baseline actual emissions need only be adjusted if the state has taken credit for such emissions reductions in an attainment demonstration or maintenance plan as part of the demonstration of attainment or as reasonable further progress to attain the NAAQS.

(iv) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24 month period must be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24 month period can be used for each regulated NSR pollutant.

(v) The average rate shall not be based on any consecutive 24 month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required under (b)(ii) and (iii) of this subsection.

(c) For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit. In the latter case, fugitive emissions, to the extent quantifiable, shall be included only if the emissions unit is part of one of the source categories listed in subsection (14)(e) of this section, the definition of major stationary source, or if the emissions unit is located at a major stationary source that belongs to one of the listed source categories.

(d) For a PAL for a major stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in (a) of this subsection, for other existing emissions units in accordance with the procedures contained in (b) of this subsection, and for a new emissions unit in accordance with the procedures contained in (c) of this subsection, except that fugitive emissions (to the extent quantifiable) shall be included regardless of the source category.

(3) "Best available control technology" (BACT) means an emissions limitation (including a visible emissions standard) based on the maximum degree of reduction for each regulated NSR pollutant which would be emitted from any proposed major stationary source or major modification which the reviewing authority, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines if it is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such pollutant. In no event shall application of best available control technology result in emissions of any pollutant which would exceed the emissions allowed by any applicable standard under 40 CFR Part 60 or 61. If the reviewing authority determines that technological or economic limitations on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational standard, or combination thereof, may be prescribed instead to satisfy the requirement for the application of BACT. Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for compliance by means which achieve equivalent results.

(4) "Building, structure, facility, or installation" means all of the pollutant-emitting activities which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person (or persons under common control) except the activities of any vessel. Pollutant-emitting activities shall be considered as part of the same industrial grouping if they belong to the same major group (i.e., which have the same two-digit code) as described in the Standard Industrial Classification Manual, 1972, as amended by the 1977 Supplement (U.S. Government Printing Office stock numbers 4101-0065 and 003-005-00176-0, respectively).

(5) "Clean coal technology" means any technology, including technologies applied at the precombustion, combustion, or post combustion stage, at a new or existing facility which will achieve significant reductions in air emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity, or process steam which was not in widespread use as of November 15, 1990.

(6) "Clean coal technology demonstration project" means a project using funds appropriated under the heading "Department of Energy-Clean Coal Technology," up to a total amount of two and one-half billion dollars for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the Environmental Protection Agency. The federal contribution for a qualifying project shall be at least twenty percent of the total cost of the demonstration project.

(7) "Construction" means any physical change or change in the method of operation (including fabrication, erection, installation, demolition, or modification of an emissions unit) that would result in a change in emissions.

(8) "Continuous emissions monitoring system" (CEMS) means all of the equipment that may be required to meet the data acquisition and availability requirements of this section, to sample, condition (if applicable), analyze, and provide a record of emissions on a continuous basis.

(9) "Continuous parameter monitoring system" (CPMS) means all of the equipment necessary to meet the data acquisition and availability requirements of this section, to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and to record average operational parameter value(s) on a continuous basis.

(10) "Continuous emissions rate monitoring system" (CERMS) means the total equipment required for the determination and recording of the pollutant mass emissions rate (in terms of mass per unit of time).

(11) "Electric utility steam generating unit" means any steam electric generating unit that is constructed for the purpose of supplying more than one-third of its potential electric output capacity and more than 25 MW electrical output to any utility power distribution system for sale. Any steam supplied to a steam distribution system for the purpose of providing steam to a steam-electric generator that would produce electrical energy for sale is also considered in determining the electrical energy output capacity of the affected facility.

(12) "Emissions unit" means any part of a stationary source that emits or would have the potential to emit any regulated NSR pollutant and includes an electric steam generating unit. For purposes of this section, there are two types of emissions units:

(a) A new emissions unit is any emissions unit which is (or will be) newly constructed and which has existed for less than 2 years from the date such emissions unit first operated.

(b) An existing emissions unit is any emissions unit that is not a new emissions unit. A replacement unit, as defined in subsection (25) of this section is an existing emissions unit.

(13) "Fugitive emissions" means those emissions which could not reasonably pass through a stack, chimney, vent or other functionally equivalent opening. Fugitive emissions, to the extent quantifiable, are addressed as follows for the purposes of this section:

(a) In determining whether a stationary source or modification is major, fugitive emissions from an emissions unit are included only if the emissions unit is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, or the emissions unit is located at a stationary source that belongs to one of those source categories. Fugitive emissions are not included for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source and that are not, by themselves, part of a listed source category.

(b) For purposes of determining the net emissions increase associated with a project, an increase or decrease in fugitive emissions is creditable only if it occurs at an emissions unit that is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, or if the emission unit is located at a major stationary source that belongs to one of the listed source categories. Fugitive emission increases or decreases are not creditable for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, and that are not, by themselves, part of a listed source category.

(c) For purposes of determining the projected actual emissions of an emissions unit after a project, fugitive emissions are included only if the emissions unit is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, or if the emission unit is located at a major stationary source that belongs to one of the listed source categories. Fugitive emissions are not included for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, and that are not, by themselves, part of a listed source category.

(d) For purposes of determining the baseline actual emissions of an emissions unit, fugitive emissions are included only if the emissions unit is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, or if the emission unit is located at a major stationary source that belongs to one of the listed source categories, except that, for a PAL, fugitive emissions shall be included regardless of the source category. With the exception of PALs, fugitive emissions are not included for those emissions units located at a facility whose primary activity is not represented by one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, and that are not, by themselves, part of a listed source category.

(b) The most stringent emissions limitation which is achieved in practice by such class or category of stationary sources. This limitation, when applied to a modification, means the lowest achievable emissions rate for the new or modified emissions units within a stationary source.

(21) "Predictive emissions monitoring system" (PEMS) means all of the equipment necessary to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and calculate and record the mass emissions rate (for example, lb/hr) on a continuous basis.

(22) "Prevention of significant deterioration (PSD) permit" means any permit that is issued under the major source preconstruction permit program that has been approved by the administrator and incorporated into the plan to implement the requirements of 40 CFR 51.166, or under the program in 40 CFR 52.21.

(23) "Project" means a physical change in, or change in the method of operation of, an existing major stationary source.

(24) "Projected actual emissions" means:

(a) The maximum annual rate, in tons per year, at which an existing emissions unit is projected to emit a regulated NSR pollutant in any one of the five years (12 month period) following the date the unit resumes regular operation after the project, or in any one of the 10 years following that date, if the project involves increasing the emissions unit's design capacity or its potential to emit of that regulated NSR pollutant and full utilization of the unit would result in a significant emissions increase or a significant net emissions increase at the major stationary source.

(b) In determining the projected actual emissions before beginning actual construction, the owner or operator of the major stationary source:

(i) Shall consider all relevant information including, but not limited to, historical operational data, the company's own representations, the company's expected business activity and the company's highest projections of business activity, the company's filings with the state or federal regulatory authorities, and compliance plans under the approved plan; and

(ii) Shall include emissions associated with startups, shutdowns, and malfunctions; and, for an emissions unit that is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source, or for an emissions unit that is located at a major stationary source that belongs to one of the listed source categories, shall include fugitive emissions (to the extent quantifiable); and

(iii) Shall exclude, in calculating any increase in emissions that results from the particular project, that portion of the unit's emissions following the project that an existing unit could have accommodated during the consecutive 24 month period used to establish the baseline actual emissions and that are also unrelated to the particular project, including any increased utilization due to product demand growth; or

(iv) In lieu of using the method set out in (b) of this subsection, the owner or operator may elect to use the emissions unit's potential to emit, in tons per year. For this purpose, if the emissions unit is part of one of the source categories listed in subsection (((14)))(15)(e) of this section, the definition of major stationary source or if the emissions unit is located at a major stationary source that belongs to one of the listed source categories, the unit's potential to emit shall include fugitive emissions (to the extent quantifiable).

(iii) Any pollutant that is identified under this subsection as a constituent or precursor of a general pollutant listed in (a)(i) or (ii) of this subsection, provided that such constituent or precursor pollutant may only be regulated under NSR as part of regulation of the general pollutant. For purposes of NSR precursor pollutants are the following:

(A) Volatile organic compounds and nitrogen oxides are precursors to ozone in all ozone nonattainment areas.

(B) Sulfur dioxide and nitrogen oxides are precursors to PM-2.5 in all PM-2.5 nonattainment areas.

Compliance with emissions limitations for PM-2.5 issued prior to this date shall not be based on condensable particulate matter unless required by the terms and conditions of the permit or the applicable implementation plan. Applicability determinations for PM-2.5 made prior to the effective date of SWCAA 400-800 through 400-850 made without accounting for condensable particulate matter shall not be considered in violation of SWCAA 400-800 through 400-850.

(26) "Replacement unit" means:

(a) An emissions unit for which all the criteria listed below are met:

(i) The emissions unit is a reconstructed unit within the meaning of 40 CFR 60.15 (b)(1), or the emissions unit completely takes the place of an existing emissions unit.

(ii) The emissions unit is identical to or functionally equivalent to the replaced emissions unit.

(iii) The replacement does not alter the basic design parameters of the process unit. Basic design parameters are:

(A) Except as provided in (a)(iii)(C) of this subsection, for a process unit at a steam electric generating facility, the owner or operator may select as its basic design parameters either maximum hourly heat input and maximum hourly fuel consumption rate or maximum hourly electric output rate and maximum steam flow rate. When establishing fuel consumption specifications in terms of weight or volume, the minimum fuel quality based on British thermal units content must be used for determining the basic design parameter(s) for a coal-fired electric utility steam generating unit.

(B) Except as provided in (a)(iii)(C) of this subsection, the basic design parameter(s) for any process unit that is not at a steam electric generating facility are maximum rate of fuel or heat input, maximum rate of material input, or maximum rate of product output. Combustion process units will typically use maximum rate of fuel input. For sources having multiple end products and raw materials, the owner or operator should consider the primary product or primary raw material of the process unit when selecting a basic design parameter.

(C) If the owner or operator believes the basic design parameter(s) in (a)(iii)(A) and (B) of this subsection is not appropriate for a specific industry or type of process unit, the owner or operator may propose to the reviewing authority an alternative basic design parameter(s) for the source's process unit(s). If the reviewing authority approves of the use of an alternative basic design parameter(s), the reviewing authority will issue a new permit or modify an existing permit that is legally enforceable that records such basic design parameter(s) and requires the owner or operator to comply with such parameter(s).

(D) The owner or operator shall use credible information, such as results of historic maximum capability tests, design information from the manufacturer, or engineering calculations, in establishing the magnitude of the basic design parameter(s) specified in (a)(iii)(A) and (B) of this subsection.

(E) If design information is not available for a process unit, then the owner or operator shall determine the process unit's basic design parameter(s) using the maximum value achieved by the process unit in the five-year period immediately preceding the planned activity.

(F) Efficiency of a process unit is not a basic design parameter.

(iv) The replaced emissions unit is permanently removed from the major stationary source, otherwise permanently disabled, or permanently barred from operation by a permit that is enforceable as a practical matter. If the replaced emissions unit is brought back into operation, it shall constitute a new emissions unit.

(b) No creditable emission reductions shall be generated from shutting down the existing emissions unit that is replaced.

(27) "Reviewing authority" means the same as "permitting authority" as defined in SWCAA 400-030.

(28) "Significant" means:

(a) In reference to a net emissions increase or the potential of a source to emit any of the following pollutants, a rate of emissions that would equal or exceed any of the following rates:

(b) Notwithstanding the significant emissions rate for ozone, significant means, in reference to an emissions increase or a net emissions increase, any increase in actual emissions of volatile organic compounds that would result from any physical change in, or change in the method of operation of, a major stationary source locating in a serious or severe ozone nonattainment area that is subject to sections 181-185B, of the Federal Clean Air Act, if such emissions increase of volatile organic compounds exceeds 25 tons per year.

(c) For the purposes of applying the requirements of SWCAA 400-830 (1)(i) to modifications at major stationary sources of nitrogen oxides located in an ozone nonattainment area or in an ozone transport region, the significant emission rates and other requirements for volatile organic compounds in (a), (b), and (e) of this subsection, of the definition of significant, shall apply to nitrogen oxides emissions.

(d) Notwithstanding the significant emissions rate for carbon monoxide under (a) of this subsection, the definition of significant, significant means, in reference to an emissions increase or a net emissions increase, any increase in actual emissions of carbon monoxide that would result from any physical change in, or change in the method of operation of, a major stationary source in a serious nonattainment area for carbon monoxide if such increase equals or exceeds 50 tons per year, provided the administrator has determined that stationary sources contribute significantly to carbon monoxide levels in that area.

(e) Notwithstanding the significant emissions rates for ozone under (a) and (b) of this subsection, the definition of significant, any increase in actual emissions of volatile organic compounds from any emissions unit at a major stationary source of volatile organic compounds located in an extreme ozone nonattainment area that is subject to sections 181-185B of the Federal Clean Air Act shall be considered a significant net emissions increase.

(29) "Significant emissions increase" means, for a regulated NSR pollutant, an increase in emissions that is significant for that pollutant.

(30) "Source" and "stationary source" means any building, structure, facility, or installation which emits or may emit a regulated NSR pollutant.

(31) "Temporary clean coal technology demonstration Project" means a clean coal technology demonstration project that is operated for a period of five years or less, and which complies with the state implementation plan for the state in which the project is located and other requirements necessary to attain and maintain the National Ambient Air Quality Standards during the project and after it is terminated.
