     (a) General applicability.
         (1) The requirements of this Part shall apply to the Construction of any new major stationary source or any project that is a major modification at an existing major stationary source in an area designated as attainment or unclassifiable under sections 107(d)(1)(A)(ii) or (iii) of the Act.
         (2) The requirements of OAC 252:100-8-34 through 252:100-8-36.2 apply to the construction of any new major stationary source or the major modification of any existing major stationary source, except as this Part otherwise provides.
         (3) No new major stationary source or major modification to which the requirements of OAC 252:100-8-34 through 252:100-8-36.2(b) apply shall begin actual construction without a permit that states that the major stationary source or major modification will meet those requirements.
         (4) The requirements of OAC 252:100-8, Parts 1, 3, and 5 also apply to the construction of all new major stationary sources and major modifications.
     (b) Major modification.
         (1) Major modification applicability determination.
             (A) Except as otherwise provided in OAC 252:100-8-30(c), and consistent with the definition of "major modification", a project is a major modification for a regulated NSR pollutant if it causes two types of emissions increases:
               (i) a significant emissions increase and
               (ii) a significant net emissions increase.
            (B) The project is not a major modification if it  does not cause a significant emissions increase. If the project causes a significant emissions increase, then the project is a major modification only if it also results in a significant net emissions increase.
         (2) Calculating significant emissions increase and significant net emissions increase before beginning actual construction. The procedure for calculating whether a significant emissions increase will occur depends upon the type of emissions units being modified, according to OAC 252:100-8-30(b)(3) through (5). This is the first step in determining if a proposed modification would be considered a major modification. The procedure for calculating whether a significant net emissions increase will occur at the major stationary source is contained in the definition of "net emissions increase". This is the second step in the process of determining if a proposed modification is a major modification. Both steps occur prior to the beginning of actual construction. Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.
         (3) Actual-to-projected-actual applicability test for projects that only involve existing emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit, equals or exceeds the amount that is significant for that pollutant.
         (4) Actual-to-potential test for projects that only involve construction of a new emissions unite(s). A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions of these units before the project equals or exceeds the amount that is significant for that pollutant.
         (5) Hybrid test for projects that involve multiple types of emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method specified in OAC 252:100-8-30(b)(3) or (4) as applicable with respect to each emissions unit, for each type of emissions unit equals or exceeds the amount that is significant for that pollutant
         (6) Actual-to-potential test for projects that only involve existing emissions units. In lieu of using the actual-to-projected-actual test, owners or operators may choose to use the actual-to-potential test to determine if a significant emissions increase of a regulated NSR pollutant will result from a proposed project. A significant emissions increase of a regulated NSR pollutant will occur if the sum of the difference between the potential emissions and the baseline actual emissions for each existing emissions unit, equals or exceeds the amount that is significant for that pollutant. Owners or operators who use the actual to potential test will not be subject to the recordkeeping requirements in OAC 252:100-8-36.2(c).
     (c) Plantwide applicability limitation (PAL). Major stationary sources seeking to obtain or maintain a PAL shall comply with the requirements under OAC 252:100-8-38.

    The following words and terms when used in this Part shall have the following meaning, unless the context clearly indicates otherwise. All terms used in this Part that are not defined in this Section shall have the meaning given to them in OAC 252:100-1-3, 252:100-8-1.1, or in the Oklahoma Clean Air Act.
    "Actual emissions" means the actual rate of emissions of a regulated NSR pollutant from an emissions unit, as determined in accordance with paragraphs (A) through (C) of this definition, except that this definition shall not apply for calculating whether a significant emissions increase has occurred, or for establishing a PAL under OAC 252:100-8-38. Instead, the definitions of "projected actual emissions" and "baseline actual emissions" shall apply for those purposes.
         (A) In general, actual emissions as of a particular date shall equal the average rate in TPY 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 Director 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.
         (B) The Director may presume that source-specific allowable emissions for the unit are equivalent to the actual emissions of the unit.
         (C) 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.
    "Allowable emissions" means the emission rate of a stationary source calculated using the maximum rated capacity of the source (unless the source is subject to enforceable limits which restrict the operating rate, or hours of operation, or both) and the most stringent of the following:
         (A) the applicable standards as set forth in 40 CFR Parts 60 and 61;
         (B) the applicable State rule allowable emissions; or,
         (C) the emissions rate specified as an enforceable permit condition.
    "Baseline actual emissions" means the rate of emissions, in TPY, of a regulated NSR pollutant, as determined in accordance with paragraphs (A) through (E) of this definition.
         (A) The baseline actual emissions shall be based on current emissions data and the unit's utilization during the period chosen. Current emission data means the most current and accurate emission factors available and could include emissions used in the source's latest permit or permit application, the most recent CEM data, stack test data, manufacturer's data, mass balance, engineering calculations, and other emission factors.
         (B) For any existing electric utility steam generating unit (EUSGU), baseline actual emissions means the average rate, in TPY, 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 the date that a complete permit application is received by the Director for a permit required under OAC 252:100-8. The Director 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 fugitive emissions to the extent quantifiable, and emissions associated with start-ups, shutdowns, and malfunctions.
             (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) For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for all the emissions units affected by the project. 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 TPY, and for adjusting this amount if required by (B)(ii) of this definition.
         (C) For an existing emissions unit (other than an EUSGU), baseline actual emissions means the average rate in TPY, at which the emissions unit actually emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the 10-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 Director for a permit required either under this Part 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 fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions.
             (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 MACT standard that the Administrator proposed or promulgated under 40 CFR 63, the baseline actual emissions need only be adjusted if DEQ has taken credit for such emissions reduction in an attainment demonstration or maintenance plan consistent with requirements of 40 CFR 51.165(a)(3)(ii)(G).
             (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 TPY, and for adjusting this amount if required by (C)(ii) and (iii) of this definition.
         (D) 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.
         (E) For a PAL for a stationary source, the baseline actual emissions shall be calculated for existing EUSGU in accordance with the procedures contained in paragraph (B) of this definition, for other existing emissions units in accordance with the procedures contained in Paragraph (C) of this definition, and for a new emissions unit in accordance with the procedures contained in paragraph (D) of this definition.
    "Baseline area" means any intrastate areas (and every part thereof) designated as attainment or unclassifiable under section 107(d)(1)(A)(ii) or (iii) of the Act in which the major source or major modification establishing the minor source baseline date would construct or would have an air quality impact for the pollutant for which the baseline date is established, as follows: Equal to or greater than 1 μg/m³ (annual average) for SO₂, NO₂, or PM₁₀; or equal or greater than 0.3 μg/m³ (annual average) for PM_2.5.
         (A) Area redesignations under section 107(d)(1)(A)(ii) or (iii) of the Act cannot intersect or be smaller than the area of impact of any major stationary source or major modification which:
             (i) establishes a minor source baseline date; or
             (ii) is subject to 40 CFR 52.21 or OAC 252:100-8, Part 7, and would be constructed in the same State as the State proposing the redesignation.
         (B) Any baseline area established originally for the TSP increments shall remain in effect and shall apply for purposes of determining the amount of available PM₁₀ increments, except that such baseline area shall not remain in effect if the Director rescinds the corresponding minor source baseline date in accordance with paragraph (D) of the definition of "baseline date".
    "Baseline concentration" means that ambient concentration level that exists in the baseline area at the time of the applicable minor source baseline date.
         (A) A baseline concentration is determined for each pollutant for which a minor source baseline date is established and shall include:
             (i) the actual emissions representative of sources in existence on the applicable minor source baseline date, except as provided in (B) of this definition.
             (ii) the allowable emissions of major Stationary sources that commenced construction before the major source baseline date, but were not in operation by the applicable minor source baseline date.
         (B) The following will not be included in the Baseline concentration and will affect the applicable Maximum allowable increase(s):
             (i) actual emissions from any major stationary source on which construction commenced after the major source baseline date; and,
             (ii) actual emissions increases and decreases at any stationary source occurring after the minor source baseline date.
    "Baseline date" means:
         (A) Major source baseline date means:
             (i) in the case of PM₁₀ and sulfur dioxide, January 6, 1975;
             (ii) in the case of nitrogen dioxide, February 8, 1988; and
             (iii) in the case of PM_2.5, October 20, 2010.
         (B) Minor source baseline date means the earliest date after the trigger date on which a major stationary source or major modification (subject to 40 CFR 52.21 or OAC 252:100-8, Part 7) submits a complete application. The trigger date is:
             (i) in the case of PM₁₀ and sulfur dioxide, August 7, 1977;
             (ii) in the case of nitrogen dioxide, February 8, 1988; and
             (iii) in the case of PM2.5, October 20, 2011.
         (C) The baseline date is established for each pollutant for which increments or other equivalent measures have been established if:
             (i) the area in which the proposed source or modification would construct is designated as attainment or unclassifiable under section 107(d)(1)(A)(ii) or (iii) of the Act for the pollutant on the date of its complete application under 40 CFR 52.21 or under OAC 252:100-8, Part 7; and
             (ii) in the case of a major stationary source, the pollutant would be emitted in significant amounts, or, in the case of a major modification, there would be a significant net emissions increase of the pollutant.
         (D) Any minor source baseline date established originally for the TSP increments shall remain in effect and shall apply for purposes of determining the amount of available PM10 increments, except that the Director may rescind any such minor source baseline date where it can be shown, to the satisfaction of the Director, that the emissions increase from the major stationary source, or the net emissions increase from the major modification, responsible for triggering that date did not result in a significant amount of PM₁₀ emissions.
    "Begin actual construction" means in general, initiation of physical on-site construction activities on an emissions unit which are of a permanent nature.
         (A) Such activities include, but are not limited to, installation of building supports and foundations, laying of underground pipework, and construction of permanent storage structures.
         (B) With respect to a change in method of operation this term refers to those on-site activities, other than preparatory activities, which mark the initiation of the change.
    "Best available control technology" or "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 Director, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combination techniques for control of such pollutant. In no event shall application of BACT result in emissions of any pollutant which would exceed the emissions allowed by any applicable standard under 40 CFR parts 60 and 61. If the Director 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.
    "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.
    "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 $2,500,000,000 for commercial demonstration of clean coal technology, or similar projects funded through appropriations for the EPA. The Federal contribution for a qualifying project shall be at least 20% of the total cost of the demonstration project.
    "Commence" means, as applied to construction of a major stationary source or major modification, that the owner or operator has all necessary preconstruction approvals or permits and either has:
         (A) begun, or caused to begin, a continuous program of actual on-site construction of the source, to be completed within a reasonable time; or,
         (B) entered into binding agreements or contractual obligations, which cannot be cancelled or modified without substantial loss to the owner or operator, to undertake a program of actual construction of the source to be completed within a reasonable time.
    "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.
    "Continuous emissions monitoring system" or "CEMS" means all of the equipment that may be required to meet the data acquisition and availability requirements to sample, condition (if applicable), analyze, and provide a record of emissions on a continuous basis.
    "Continuous emissions rate monitoring system" or "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).
    "Continuous parameter monitoring system" or "CPMS" means all of the equipment necessary to meet the data acquisition and availability requirements 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.
    "Electric utility steam generating unit" or "EUSGU" 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.
    "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 EUSGU. There are two types of emissions units as described in paragraphs (A) and (B) of this definition.
         (A) A new emissions unit is any emissions unit that is (or will be) newly constructed and that 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 does not meet the requirements in paragraph (A) of this definition. A replacement unit is an existing emissions unit.
    "Federal Land Manager" means with respect to any lands in the United States, the Secretary of the department with authority over such lands.
    "High terrain" means any area having an elevation 900 feet or more above the base of the stack of a source.
    "Innovative control technology" means any system of air pollution control that has not been adequately demonstrated in practice, but would have a substantial likelihood of achieving greater continuous emissions reduction than any control system in current practice or of achieving at least comparable reductions at lower cost in terms of energy, economics, or non-air quality environmental impacts.
    "Low terrain" means any area other than high terrain.
    "Major modification" means:
         (A) Any physical change in or change in the method of operation of a major stationary source that would result in a significant emissions increase of a regulated NSR pollutant and a significant net emissions increase of that pollutant from the major stationary source is a major modification.
             (i) Any significant emissions increase from any emissions units or net emissions increase at a major stationary source that is significant for VOC or NO_X shall be considered significant for ozone.
             (ii) A physical change or change in the method of operation shall not include:
                 (I) routine maintenance, repair and replacement;
                 (II) use of an alternative fuel or raw material by reason of any order under sections 2(a) and (b) of the Energy Supply and Environmental Coordination Act of 1974 (or any superseding legislation) or by reason of a natural gas curtailment plan pursuant to the Federal Power Act;
                 (III) use of an alternative fuel by reason of an order or rule under section 125 of the Act;
                 (IV) use of an alternative fuel at a steam generating unit to the extent that the fuel is generated from municipal solid waste;
                 (V) use of an alternative fuel or raw Material by a stationary source which the source was capable of accommodating before January 6, 1975, (unless such change would be prohibited under any enforceable permit condition which was established after January 6, 1975) or the source is approved to use under any permit issued under 40 CFR 52.21 or OAC 252:100-7 or 252:100-8;
                 (VI) an increase in the hours of operation or in the production rate, unless such change would be prohibited under any federally enforceable permit condition which was established after January 6, 1975;
                 (VII) any change in source ownership;
                 (VIII) the installation, operation, cessation, or removal of a temporary clean coal technology demonstration project, provided the project complies with OAC 252:100 and other requirements necessary to attain and maintain the NAAQS during the project and after it is terminated;
                 (IX) the installation or operation of a permanent clean coal technology demonstration project that constitutes repowering, provided that the project does not result in an increase in the potential to emit of any regulated pollutant (on a pollutant-by-pollutant basis) emitted by the unit; or
                 (X) the reactivation of a very clean coal-fired EUSGU.
         (B) This definition shall not apply with respect to a particular regulated NSR pollutant when the major stationary source is complying with the requirements under OAC 252:100-8-38 for a PAL for that pollutant. Instead, the definition of "PAL major modification" at 40 CFR 51.166(w)(2)(viii) shall apply.
    "Major stationary source" means
         (A) A major stationary source is:
             (i) any of the following stationary sources of air pollutants which emits, or has the potential to emit, 100 TPY or more of a regulated NSR pollutant:

         (C) The fugitive emissions of a stationary source shall not be included in determining for any of the purposes of this Part whether it is a major stationary source, unless the source belongs to one of the following categories of stationary sources:
             (i) the stationary sources listed in (A)(i) of this definition;
             (ii) any other stationary source category which, as of August 7, 1980, is being regulated under section 111 or 112 of the Act.

         (G) An increase that results from a physical change at a source occurs when the emissions unit on which construction occurred becomes operational and begins to emit a particular pollutant. Any replacement unit that requires shakedown becomes operational only after a reasonable shakedown period, not to exceed 180 days.
         (H) Paragraph (A) of the definition of "actual emissions" shall not apply for determining creditable increases and decreases.
    "Potential to emit" means the maximum capacity of a stationary source to emit a pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the source to emit a pollutant, including air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored or processed, shall be treated as part of its design if the limitation or the effect it would have on emissions is enforceable. Secondary emissions do not count in determining the potential to emit of a stationary source.
    "Predictive emissions monitoring system" or "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.
    "Prevention of Significant Deterioration (PSD) program" means a 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 the program in 40 CFR 52.21. Any permit issued under such a program is a major NSR permit.

         (B) In determining the projected actual emissions under paragraph (A) of this definition (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 fugitive emissions to the extent quantifiable and emissions associated with start-ups, shutdowns, and malfunctions; 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)(i) through (iii) of this definition, may elect to use the emissions unit's potential to emit, in TPY.
    "Reactivation of a very clean coal-fired electric utility steam generating unit" means any physical change or change in the method of operation associated with the commencement of commercial operations by a coal-fired utility unit after a period of discontinued operation where the unit:

Explanation: SIP does not include OAC 252:100-8-35(a)(2) effective on 7/1/2011 and submitted 2/6/2012.
    (a) Source impact analysis (impact on NAAQS and PSD increment).
         (1) Required demonstration. The owner or operator of the proposed source or modification shall demonstrate that, as of the source's start-up date, allowable emissions increases from that source or modification, in conjunction with all other applicable emissions increases or reductions (including secondary emissions) would not cause or contribute to any increase in ambient concentrations that would exceed:
             (A) any NAAQS in any air quality control region; or
             (B) the remaining available PSD increment for the specified air contaminants in any area as determined by the Director.
         (2) NOT IN SIP
     (b) Air quality models.
         (1) All estimates of ambient concentrations required under this Part shall be based on the applicable air quality models, data bases, and other requirements specified in appendix W of 40 CFR 51 (Guideline on Air Quality Models) as it existed on January 2, 2006.
         (2) Where an air quality model specified in appendix W of 40 CFR 51 (Guideline on Air Quality Models) as it existed on January 2, 2006, is inappropriate, the model may be modified or another model substituted, as approved by the Administrator. Such a modification or substitution of a model may be made on a case-by-case basis or, where appropriate, on a generic basis. Modified or substitute models shall be submitted to the Administrator with written concurrence of the Director. In addition, use of a modified or substituted model must be subject to notice and opportunity for public comment under procedures set forth in Sec. 51.102 as it existed on January 2, 2006.
     (c) Air quality analysis.
         (1) Preapplication analysis.
             (A) Ambient air quality analysis. Any application for a permit under this Part shall contain, as the Director determines appropriate, an analysis of ambient air quality in the area that the major stationary source or major modification would affect for each of the following pollutants:
                 (i) for a new source, each regulated pollutant that it would have the potential to emit in a significant amount;
                 (ii) for a major modification, each regulated pollutant for which it would result in a significant net emissions increase.
             (B) Monitoring requirements.
                 (i) Non-NAAQS pollutants. For any such pollutant for which no NAAQS exists, the analysis shall contain such air quality monitoring data as the Director determines is necessary to assess the ambient air quality for that pollutant in that area.
                 (ii) NAAQS pollutants. For visibility and any Pollutant, other than VOC, for which a NAAQS does exist, the analysis shall contain continuous air quality monitoring data gathered to determine if emissions of that pollutant would cause or contribute to a violation of the NAAQS or any PSD increment.
             (C) Monitoring method. With respect to any Requirements for air quality monitoring PM₁₀ under OAC 252:100-8-33(e)(1) and (2), the owner or operator of the source or modification shall use a monitoring method approved by the Director and shall estimate the ambient concentrations of PM_l0 using the data collected by such approved monitoring method in accordance with estimating procedures approved by the Director.
             (D) Monitoring period. In general, the required continuous air monitoring data shall have been gathered over a period of up to one year and shall represent the year preceding submission of the application. Ambient monitoring data gathered over a period shorter than one year (but no less than four months) or for a time period other than immediately preceding the application may be acceptable if such data are determined by the Director to be within the time period that maximum pollutant concentrations would occur, and to be complete and adequate for determining whether the source or modification will cause or contribute to a violation of any applicable NAAQS or consume more than the remaining available PSD increment.
             (E) Monitoring period exceptions.
                 (i) Exceptions for applications that became effective between June 8, 1981, and February 9, 1982. For any application which became complete except for the monitoring requirements of OAC 252:100-8-35(c)(1)(B)(ii) and 252:100-8-35(c)(1)(D), between June 8, 1981, and February 9. 1982, the data that 252:100-8-35(c)(1)(B)(ii) requires shall have been gathered over the period from February 9, 1981, to the date the application became otherwise complete, except that:
                     (I) If the source or modification would have been major for that pollutant under 40 CFR 52.21 as in effect on June 19, 1978, any monitoring data shall have been gathered over the period required by those regulations.
                      (II) If the Director determines that a complete and adequate analysis can be accomplished with monitoring data over a shorter period, not to be less than four months, the data that OAC 252:100-8-35(c)(1)(B)(ii) requires shall have been gathered over that shorter period.
                      (III) If the monitoring data would relate exclusively to ozone and would not have been required under 40 CFR 52.21 as in effect on June 19, 1978, the Director may waive the otherwise applicable requirements of OAC 252:100-8-35(c)(1)(E)(i) to the extent that the applicant shows that the monitoring data would be unrepresentative of air quality over a full year.
                 (ii) Monitoring period exception for PM₁₀. For any application that became complete, except for the Requirements of OAC 252:100-8-35(c)(1)(B)(ii) and 252:100-8-35(c)(1)(D) pertaining to monitoring of PM₁₀, after December 1, 1988, and no later than August 1, 1989, the data that 252:100-8-35(c)(1)(B)(ii) requires shall have been gathered over at least the period from August 1, 1988, to the date the application becomes otherwise complete, except that if the Director determines that a complete and adequate analysis can be accomplished with monitoring data over a shorter period (not less than 4 months), the data that 252:100-8-35(c)(1)(B)(ii) requires shall have been gathered over that shorter period.
             (F) Ozone post-approval monitoring. The owner or operator of a proposed major stationary source or major modification of VOC who satisfies all conditions of OAC 252:100-8-54 and 40 CFR 51, Appendix S, Section IV as it existed on January 16, 1979, may provide post-approval monitoring data for ozone in lieu of providing preconstruction data as required under OAC 252:100-8-35(c)(1).
         (2) Post-construction monitoring. The owner or operator of a new major stationary source or major modification shall conduct, after construction, such ambient monitoring and visibility monitoring as the Director determines is necessary to determine the effect its emissions may have, or are having, on air quality in any area.
         (3) Operation of monitoring stations. The operation of monitoring stations for any air quality monitoring required under this Part shall meet the requirements of 40 CFR 58 Appendix B as it existed January 2, 2006.

     (a) Obtaining and complying with preconstruction permits. Any owner or operator who constructs or operates a source or modification not in accordance with the application submitted pursuant to this Part or with the terms of any  approval to construct or any owner or operator of a source or modification subject to this Part who commences construction after the effective date of these regulations without applying for and receiving approval hereunder, shall be subject to appropriate enforcement action.
     (b) Consequences of relaxation of permit requirements. When a source or modification becomes major solely by virtue of a relaxation in any enforceable permit limitation established after August 7, 1980, on the capacity of the source or modification to emit a pollutant, such as a restriction on hours of operation, then the requirements of OAC 252:100-8, Parts 1, 3, 5, and 7 and 252:100-8-34 through 252:100-8-37 shall apply to that source or modification as though construction had not yet commenced on it.
     (c) Requirements when using projected actual emissions. The following specific provisions apply to projects at existing emissions units at a major stationary source (other than projects at a source with a PAL) when the owner or operator elects to use the method specified in (B)(i) through (iii) of the definition of "projected actual emissions" for calculating projected actual emissions.
         (1) Before beginning actual construction of the project the owner or operator shall document and maintain a record of the following information:
             (A) A description of the project;
                (B) Identification of the existing emissions unit(s) whose emissions of a regulated NSR pollutant could be affected by the project; and
             (C) A description of the applicability test used to determine that the project is not a major modification for any regulated NSR pollutant, including the baseline actual emissions, the projected actual emissions, the amount of emissions excluded under (B)(iii) of the definition of "projected actual emissions" and an explanation for why such amount was excluded, and any netting calculations, if applicable.
         (2) If the emissions unit is an existing EUSGU, before beginning actual construction. the owner or operator shall provide a copy of the information set out in OAC 252:100-8-36.2(c)(l) to the Director. Nothing in OAC 252: 100-8-36.2(c)(2) shall be construed to require the owner or operator of such a unit to obtain any determination from the Director before beginning actual construction.
         (3) The owner or operator shall monitor the emissions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions unit identified in OAC 252:100-8-36.2(c)(1)(B); and calculate and maintain a record of the annual emissions, in TPY on a calendar year basis, for a period of 5 years following resumption of regular operations after the change, or for a period of 10 years following resumption of regular operations after the change if the project increases the design capacity or potential to emit of that regulated NSR pollutant at such emissions unit.
         (4) If the unit is an existing EUSGU, the owner or Operator shall submit a report to the Director within 60 days after the end of each year during which records must be generated under OAC 252:100-8-36.2(c)(3) setting out the unit's annual emissions during the calendar year that preceded submission of the report.
         (5) If the unit is an existing unit other than an EUSGU, the owner or operator shall submit a report to the Director if the annual emissions, in TPY, from the project identified in OAC 252:100-8-36.2(c)(l), exceed the baseline actual emissions (as documented and maintained pursuant to 252:100-8-36.2(c)(l)(C}) by an amount that is significant for that regulated NSR pollutant and if such emissions differ from the preconstruction projection as documented and maintained pursuant to 252:1 00-8-36.2(c)(l)(C}. Such report shall be submitted to the Director within 60 days after the end of such year. The report shall contain the following:
             (A) The name, address and telephone number of the major stationary source;
             (B) The annual emissions as calculated pursuant to OAC 252:100-8-36.2(c)(3); and
             (C) Any other information that the owner or operator wishes to include in the report (e.g.. an explanation as to why the emissions differ from the preconstruction projection).
         (6) The owner or operator of the source shall make the information required to be documented and maintained pursuant to OAC 252:100-8-36.2(c) available for review upon request for inspection by the Director or the general public.
         (7) The requirements of OAC 252:100-8-34 through 252:100-8-36.2 shall apply as if construction has not yet commenced at any time that a project is determined to be a major modification based on any credible evidence, including but not limited to emissions data produced after the project is completed. In any such case, the owner or operator may be subject to enforcement for failure to obtain a PSD permit prior to beginning actual construction.
         (8) If an owner or operator materially fails to comply with the provisions of OAC 252:100-8-36.2(c), then the calendar year emissions are presumed to equal the source's potential to emit.

     (a) An applicant for a permit for a proposed major stationary source or major modification may request the Director in writing to approve a system of innovative control technology.
     (b) The Director may determine that the innovative control technology is permissible if:
         (1) The proposed control system would not cause or contribute to an unreasonable risk to public health, welfare or safety in its operation or function.
         (2) The applicant agrees to achieve a level of continuous emissions reductions equivalent to that which would have been required for BACT under OAC 252:100-8-34(b)(1) by a date specified by the Director. Such date shall not be later than 4 years from the time of start-up or 7 years from permit issuance.
         (3) The source or modification would meet the requirements equivalent to those in OAC 252:100-8-34 and 252:100-8-35(a) based on the emissions rate that the stationary source employing the system of innovative control technology would be required to meet on the date specified by the Director.
         (4) The source or modification would not, before the date specified, cause or contribute to any violation of the applicable NAAQS, or impact any Class I area or area where an applicable increment is known to be violated.
         (5) All other applicable requirements including those for public participation have been met.
         (6) The provisions of OAC 252: 100-8-36 (relating to Class I areas) have been satisfied with respect to all periods during the life of the source or modification.
     (c) The Director shall withdraw approval to employ a system of innovative control technology made under OAC 252:100-8-37, if:
         (1) The proposed system fails by the specified date to achieve the required continuous emissions reduction rate; or,
         (2) The proposed system fails before the specified date so as to contribute to an unreasonable risk to public health, welfare or safety; or,
         (3) The Director decides at any time that the proposed system is unlikely to achieve the required level of control or to protect the public health, welfare or safety.
     (d) If a source or modification fails to meet the required level of continuous emissions reduction within the specified time period, or if the approval is withdrawn in accordance with OAC 252:100-8-37(c), the Director may allow the source or modification up to an additional 3 years to meet the requirement for application of BACT through the use of a demonstrated system of control.
