TITLE 45 LEGISLATIVE RULE DEPARTMENT OF ENVIRONMENTAL PROTECTION AIR QUALITY

SERIES 14 PERMITS FOR CONSTRUCTION AND MAJOR MODIFICATION OF MAJOR STATIONARY SOURCES FOR THE PREVENTION OF SIGNIFICANT DETERIORATION OF AIR QUALITY

§45-14-1. General. 1.1. Scope. -- This rule establishes and adopts a pr econstruction permit program in accordance with the policy of §101(b)(1) of the Clean Air Act (CAA), the purposes of §160 of the CAA, and the prevention of significant deterioration of air quality requirement s of 40 CFR §51.166. Preconstruction permits issued pursuant to this rule shall contain emission limitati ons and such other measures as may be necessary for the prevention significant deterioration of air quality. This rule provides: 1.1.a. A mechanism to ensure that economic grow th will occur in harmony with the preservation of existing clean air resources; to prevent the developmen t of any new non-attainment problems; to protect the public health and welfare from any adverse effects whic h might occur even at air quality levels better than the National Ambient Air Quality Standards; and to preserve, protect, and enhance the air quality in areas of special natural, recreational, scenic, or historic value. It is the intent of the Secretary to register and evaluate sources of air pollutants and to preclude the construction or relocation of any major stationary source or major modification in any area classified as attaining Nationa l Ambient Air Quality Standards or unclassifiable in which the establishment of such source or modificati on may interfere with the goals of the prevention of significant deterioration of air quality levels; and 1.1.b. A method to quantitatively define significant deterioration of air quality with respect to the desired degree of preservation of air quality for various areas and to set forth procedures for registration and reporting, and the criteria for obtaining a permit to cons truct or relocate a major stationary source or make a major modification to a stationary source within a d esignated attainment or unclassified area of the State of West Virginia. Such construction, modification, or relocation without such a permit is a violation of this rule. 1.2. Authority. -- W. Va. Code §22-5-4. 1.3. Filing Date. -- April 6, 2015 1.4. Effective Date. -- June 1, 2015. 1.5. Federal Regulation. -- Unless otherwise indicat ed, where reference to a federal regulation or standard appears in this rule, such regulation or standa rd will, for the purpose of this rule, be construed as that version which was in effect as of June 1, 2014. 1.6. Former Rules. -- This legislative rule ame nds 45CSR14 - “Permits for Construction and Major Modification of Major Stationary Sources for the Prevention of Significant Deterioration of Air Quality”

which was filed on April 3, 2014 a nd became effective on June 1, 2014. §45-14-2. Definitions.

2.1. “Actual emissions” means the actual rate of em issions of a pollutant from an emissions unit, as described below, except that this definition shall not apply for calculating whether a significant emissions increase has occurred, or for establishing a PAL under sec tion 25. Instead, subsections 2.63 and 2.8 shall apply for those purposes. 2.1.a. 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 Secretary may 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 ope rating hours, production rates, and types of materials processed, stored, or combusted during the selected time period. 2.1.b. The Secretary may presume that source-specifi c allowable emissions for the unit are equivalent to the actual emissions of the unit. 2.1.c. For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit of the unit on that date. 2.1.d. For an electric utility steam generating unit (other than a new unit or the replacement of an existing unit) actual emissions of the unit following the physical or operational change shall equal the representative actual annual emissions of the unit follo wing the physical or operational change, provided the source owner or operator maintains a nd submits to the Director, on an a nnual basis for a period of five (5) years from the date the unit resumes regular operati on, information demonstrating that the physical or operational change did not result in an emissions increase. A longer period, not to exceed ten (10) years, may be required by the Director if the Director determ ines such a period to be more representative of normal source operations following the phy sical or operational change. 2.2. “Actuals PAL” for a major stationary sour ce means a PAL based on the baseline actual emissions (as defined in subsection 2.8) of all emissions units (a s defined in subsection 2.27) at the source, that emit or have the potential to emit the PAL pollutant.

2.3. “Administrator” means the Administrator of the United States Environmental Protection Agency. 2.4. “Adverse impact on visibility” means visibility impairment which interferes with the management, protection, preservation or enjoyment of the visitor's visual experience of the Federal Class I area. This determination must be made on a case-by-case basis taking into account the geographic extent, intensity, duration, frequency and time of visibility impairment, a nd how these factors correlate with (1) times of visitor use of the Federal Class I area, and (2) the frequency a nd timing of natural conditions that reduce visibility. 2.5. “Air pollutants” means solids, liquids, or gases wh ich, if discharged into the air, may result in statutory air pollution. 2.6. “Air pollution” or “statutory air pollution” means and is limited to the discharge into the air by the act of man substances (liquid, solid, gaseous, organic or inorganic) in a locality, manner and amount as to be injurious to human health or welfare, animal or plan t life, or property, or which would interfere with the

245CSR14

enjoyment of life or property. 2.7. “Allowable emissions” means the emission rate of a stationary source calculated using the maximum rated capacity of the source (unless the source is subject to federally enforceable limits or limits enforceable by the Secretary which restrict the opera ting rate, or hours of operation, or both) and the most stringent of the following: 2.7.a. The applicable standards as set forth in 40 CFR Parts 60 and 61; 2.7.b. The applicable State of West Virginia emi ssions limitations or permit conditions, including those with a future compliance date; or 2.7.c. The applicable federally enforceable emissi ons limitations or permit conditions, including those with a future compliance date. 2.8. “Baseline actual emissions” means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with subdivisions 2.8.a through 2.8.d. 2.8.a. For any existing electric utility steam generating unit, baseline actual emissions means the average emission rate, in tons per year, at which th e 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 constr uction of the project. The Secretary shall allow the use of a different time period upon a determination that it is mo re representative of normal source operation. 2.8.a.1. The average rate shall include fugitive em issions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions. 2.8.a.2. The average rate shall be adjusted dow nward to exclude any noncompliant emissions that occurred while the source was operating above any emi ssion limitation that was legally enforceable during the consecutive 24-month period. 2.8.a.3. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period must be used to determin e the baseline actual emissions for the emissions units being changed. A different consecutive 24-month pe riod can be used for each regulated NSR pollutant. 2.8.a.4. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emi ssions, in tons per year, and for adjusting this amount if required by paragraph 2.8.a.2. 2.8.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 10-year period immediately preceding either the date the owner or opera tor begins actual construction of the project, or the date a complete permit application is received by the Secretary for a permit required under this rule, whichever is earlier, except that the 10-year period sh all not include any period earlier than November 15, 1990. 2.8.b.1. The average rate shall include fugitive em issions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions.

345CSR14

2.8.b.2. The average rate shall be adjusted dow nward to exclude any noncompliant emissions that occurred while the source was operating above an emissi on limitation that was legally enforceable during the consecutive 24-month period. 2.8.b.3. The average rate shall be adjusted dow nward 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 CF R 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 consistent with the requirements of 45CSR19-8.6. 2.8.b.4. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period must be used to determin e the baseline actual emissions for all the emissions units being changed. A different consecutive 24-month period can be used for each regulated NSR pollutant. 2.8.b.5. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emi ssions, in tons per year, and for adjusting this amount if required by paragra phs 2.8.b.2 and 2.8.b.3. 2.8.c. For a new emissions unit, the baseline act ual emissions for purposes of determining the emissions increase that will result from the initial cons truction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit’s potential to emit. 2.8.d. For a PAL for a stationary source, the baselin e actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures contained in subdivision 2.8.a, for other existing emissions units in accordance with the pr ocedures contained in subdivision 2.8.b, and for a new emissions unit in accordance with the procedures contained in subdivision 2.8.c.

2.9. Baseline Area. 2.9.a. “Baseline area” means any intrastate area (and every part thereof) designated as attainment or unclassifiable under §107(d)(1)(A)(ii) or (iii) of the C AA in which the major source or major modification establishing the minor source baseline date would constr uct or would have an air quality impact for the pollutant for which the baseline date is establis hed, equal to or greater than the following:

Pollutant Air Quality Impact (annual average) SO 2 1 μg/m 3

NO 2 1 μg/m 3

PM 10 1 μg/m 3

PM 2.5 0.3 μg/m 3 2.9.b. Area redesignations under §107(d)(1)(A)(ii) or ( iii) of the CAA cannot intersect or be smaller than the area of impact of any major stationary source or major modification which:

445CSR14

2.9.b.1. Establishes a minor source baseline date; or 2.9.b.2. Is subject to 40 CFR §52.21 or this rule, and would be constructed in the same state as the state proposing the redesignation. 2.9.c. Any baseline area established originally for the TSP increments shall remain in effect and shall apply for purposes of determining the amount of available PM 10 increments, except th at such baseline area shall not remain in effect if the Secretary rescinds the corresponding minor source baseline date in accordance with subdivision 2.42.d.

2.10. “Baseline concentration” means that ambient con centration level which exists in the baseline area at the time of the applicable minor source baseline date. A baseline concentration is determined for each pollutant for which a minor source baseline date is established and includes: 2.10.a. The allowable emissions of major stati onary sources which commenced construction before the major source baseline date, but were not in opera tion by the applicable minor source baseline date. 2.10.b. The actual emissions representative of sour ces in existence on the applicable minor source baseline date. However, the following will not be incl uded in the baseline concentration and will affect the applicable maximum allowable increase(s): 2.10.b.1. actual emissions from any major sta tionary source on which construction commenced after the major source baseline date; and 2.10.b.2. actual emissions increases and decreases at any stationary source occurring after the minor source baseline date. 2.11. “Begin actual construction” means, in general, initiation of physical on-s ite construction activities on an emissions unit which are of a permanent nature. Such activities include, but are not limited to, installation of building supports and foundations, laying of undergr ound pipework, and construction of permanent storage structures. With respect to a change in method of operation, this term refers to those onsite activities, other than preparatory activiti es, which mark the initiation of the change. 2.12. “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 Secretary, on a case-by-case basis, taking into account energy, envi ronmental and economic impacts and other costs, determines is achievable for such source or modi fication 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 whic h would exceed the emissions allowed by any federally enforceable emissions limitations or emissions limitations enforceable by the Secretary. If the Secretary 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 best available cont rol technology. 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 complia nce by means which achieve equivalent results.

The most stringent emissions limitation which is contained in the implementation plan of any State for such class or category of stationary source, unless the owner or operator of the proposed stationary source demonstrates that such limitations are not achievable; or 2.37.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 emission rate for the new or modified emissions units within the stationary source. In no event shall the application of the term permit a new or proposed new or modified stationary source to emit any pollutant in excess of the amount allowable under an appli cable new source standard of performance. 2.38.

This ex emption shall apply on a pollutant-by-pollutant basis. 2.40.l. The reactivation of a very clean coal-fired electric utility steam generating unit. 2.40.m. This definition shall not apply with respect to a particular regulated NSR pollutant when the major stationary source is complying with the requi rements under section 25 for a PAL for that pollutant. Instead, the definition at subsection 2.53 shall apply. 2.41. “Major modification for ozone” means a major modification for volatile organic compounds or NO X . 2.42. “Major and minor source baseline date.”

The requirements of sections 7 through 13 and sections 17 through 19 apply to the construction of any new major stationary source or the major modifica tion of any existing major stationary source, except as this rule otherwise provides. 3.3. No new major stationary source or major modi fication to which the requirements of sections 7 through 13 and sections 17 through subsection 19.7 appl y shall begin actual construction without a permit issued by the Secretary that states that the major stationary source or major modification will meet those requirements. 3.4. Determination of major modification. -- The de termination as to whether a proposed project is a major modification for a regulated NSR pollutant sh all be determined in acco rdance with the specific provisions set forth in subdivisions 3.4.a through 3.4.f. 3.4.a. Except as otherwise provided in subsections 3. 5 and 3.6, and consistent with the definition of major modification contained in subsection 2.40, a pr oject is a major modification for a regulated NSR pollutant if it causes two types of emissions incr eases -- a significant emissions increase (as defined in subsection 2.75), and a significant net emissions incr ease (as defined in subsections 2.46 and 2.74). The proposed project is not a major modification if it does not cause a significant emissions increase. If the proposed project causes a significant emissions increase, th en the project is a major modification only if it also results in a significant net emissions increase. 3.4.b. The procedure for calculating (before beginning actual construction) whether a significant emissions increase (i.e., the first step of the process) will occur depends upon the type of emissions units being modified, according to subdivisions 3.4.c through 3.4.f. The procedure for calculating (before beginning actual construction) whether a significant net emissions increase will occur at the major stationary source (i.e., the second step of the process) is containe d in the definition in subsection 2.46. Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase. 3.4.c. 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 (as defined in subsection 2.63) and the baseline actual emissions (as defined in subdivisions 2.8.a and 2.8.b), for each existing emissions unit, equals or exceeds the significant amount for that pollutant (as defined in subsection 2.74). 3.4.d. Actual-to-potential test for projects that only involve construction of a new emissions unit(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 (as defined in sub section 2.58) from each new emissions unit following completion of the project and the baseline actual emissions (as defined in subdivision 2.8.c) of these units before the project equals or exceeds the significant amount for that pollutant (as defined in subsection 2.74). 3.4.e.

Control Technology Requirements. 8.1. Any person proposing to construct or relocate a ma jor stationary source or major modification shall meet each applicable emissions limitation promulgate d by the Secretary and any applicable emissions standard or standard of performance under 40 CFR Parts 60, 61 and 63. 8.2. Any person proposing to construct a new major sta tionary source shall apply best available control technology for each regulated NSR pollutant that it w ould have the potential to emit in significant amounts. 8.3. Any person proposing a major modification of a sta tionary source shall apply best available control technology for each regulated NSR pollutant for wh ich such proposed major modification would cause a significant net emissions increase from such source. This requirement applies to each proposed emissions unit at which a net emissions increase in the pollutant would occur as a result of a physical change or change in the method of operation in the unit. 8.4. For any proposed construction of a major stati onary source or major modification which is a phased construction project, the determination of best availa ble control technology shall be reviewed and modified as appropriate at the last reasonable time which o ccurs no later than eighteen (18) months prior to commencement of construction of each independent phase of the project. At such time, the owner or operator of the applicable stationary source may be requi red to demonstrate the adequacy of any previous determination of best available control technology for the source. §45-14-9. Requirements Relating to the Source’s Impact on Air Quality. 9.1. Required Demonstration. -- Any person proposing to construct or re locate a major stationary source or to make a major modification shall demonstrate that allowable emission increases from the proposed source or modification, in conjunction with all other a pplicable emission increases or reductions (including secondary emissions) would not cause or contribute to air pollution in violation of: 9.1.a. Any National Ambient Air Quality Standard in any air quality control region; or 9.1.b. Any applicable maximum allowable incr ease over the baseline concentration in any area. 9.2. [Reserved.] §45-14-10. Modeling Requirements. 10.1.

2645CSR14

10.2. Where an air quality impact model specified in Appendix W of 40 CFR Part 51 (Guideline on Air Quality Models) is inappropriate, the model may be modified or another model substituted, provided that said modification or substitution is approve d in writing by the Administrator. §45-14-11. Air Quality Monitoring Requirements. 11.1. Any person proposing to construct or relocate a major stationary source shall provide an analysis of the ambient air quality in the area that the major st ationary source would affect for each pollutant that it would have the potential to emit in a significant amount. 11.2. Any person proposing to make a major modification to a stationary source shall provide an analysis of the ambient air quality in the area that the major modification would affect for each pollutant for which it would result in a significant net emissions increase. 11.3. For those pollutants for which no National or West Virginia Ambient Air Quality Standard exists, the analysis shall contain such air quality monitori ng data as the Secretary determines is necessary to assess ambient air quality for that pollutant in any area th at the emissions of that pollutant would affect. 11.4. For those pollutants (other than non-methane hydrocarbons) for which such an ambient air quality standard does exist, the analysis shall contain con tinuous air quality monitoring data gathered for purposes of determining whether emissions of that pollutant w ould cause or contribute to a violation of the standard or any maximum allowable increase. 11.5. All ambient air quality monitoring data that is required shall have been gathered over a period of one (1) year and shall represent the year preceding receipt of the application, except that, if the Secretary determines that a complete and adequate analysis can be accomplished with monitoring data gathered over a period shorter than one (1) year (but not to be less than four (4) months), the data that is required shall have been gathered over at least that shorter period. 11.6. Any person proposing to construct or relocat e a major stationary source or make a major modification shall, after construction of the stati onary source or modification, conduct such ambient monitoring as the Secretary determines is necessary to determine the effect emissions from the stationary source or modification may have, or are having, on air quality in any area. 11.7. Operation of monitoring stations required by section 11 shall meet the requirements of Appendix B of 40 CFR Part 58 during the operation of the monitoring stations. §45-14-12. Additional Impact Analysis Requirements. 12.1. Any person proposing to constr uct or relocate a major stationary source or make a major modification shall provide: 12.1.a. An analysis of the impairment to visibility, soils, and vegetation that would occur as a result of the source or modification and general commercial, resi dential, industrial, and other growth associated with the source or modification.

Notice to EPA. -- The Secretary shall transm it to the Administrator a copy of each permit application relating to a major stationary source or major modification impacting a Class I area and provide notice to the Administrator of every action re lated to the consideration of such permit. 13.2. Notice to Federal land managers. -- The Secr etary shall provide written notice of any permit application for a proposed major stationary source or major modification, the emissions from which may affect a Class I area, to the Federa l land manager or the Federal offici al, charged with direct responsibility for management of any lands within any such area. Su ch notification shall include a copy of all information relevant to the permit application and shall be given w ithin 30 days of receipt and at least 60 days prior to any public hearing on the application for a permit to cons truct. Such notification shall include an analysis of the proposed source's anticipated impact s on visibility in the Federal Class I area. 13.3. The Secretary shall also provide the Federal land manager or such Federal officials with a copy of the preliminary determination require d under subsection 17.2, and shall make available to them any materials used in making that determination, promptly after th e Secretary makes such determination. Finally, the Secretary shall also notify all affected Federal land managers within 30 days of receipt of any advance notification of any such permit application. 13.4. Federal Land Manager. -- The Fe deral Land Manager or the Federa l official, charged with direct responsibility for management of such lands has an affi rmative responsibility to protect the air quality related values (including visibility) of such lands and to cons ider, in consultation with the Secretary, whether a proposed source or modification will have an adverse impact on such values. 13.5. The Federal Land Manager of the affected Class I area may present to the Secretary during the public review process described in section 17 a demons tration that the emissions from the proposed major stationary source or major modification would have an adverse impact on the air quality-related values (including visibility) of any Federal mandatory Class I lands, notwithstanding that the change in air quality resulting from emissions from such source or modification would not cause or contribute to concentrations which would exceed the maximum allowable increases for a Class I area. If the Secretary concurs with such demonstration, the Secretary shall deny the permit to construct. 13.6. Class I variances. -- The owner or operator of a proposed source or modification may demonstrate to the Federal Land Manage r that the emissions from such source or modification would have no adverse impact on the air quality related values of any such lands (including visibility), notwithstanding that the change in air quality resulting from emissions from such source or modification would cause or contribute to concentrations which would exceed the maximum allowable increases for a Class I area. If the Federal land manager concurs with such de monstration and he so certifies, the Secretary may issue the permit: Provided, That the applicable requirements of this sec tion are otherwise met, to issue the permit with such emission limitations as may be necessary to assure that emissions of sulfur dioxide, PM 2.5 , PM 10 , and nitrogen oxides would not exceed the following maximum allowable increases over minor source baseline concentration for such pollutants:

Maximum Allowable Pollutant Concentration In crease over Minor Source Baseline Concentration ( μ g/m 3 )

2845CSR14

Particulate Matter: PM 2.5 , Annual arithmetic mean 4 PM 2.5 , 24-hr maximum 9 PM 10 , Annual arithmetic mean 17 PM 10 , 24-hr maximum 30 Sulfur dioxide: Annual arithmetic mean 20 24-hr maximum 91 3-hr maximum 325 Nitrogen dioxide: Annual arithmetic mean 25 13.7.

Procedures for Sources Employing Innovative Control Technology. 14.1. Any person proposing to construct or modify a major stationary source or major modification may petition the Secretary to approve a system of innovative control technology in lieu of best available control technology. Any such proposed innovative control technology shall meet the following conditions: 14.1.a. The proposed control system would not cause or contribute to an unreasonable risk to public health, welfare, or safety in its operation or function; 14.1.b. The proposed source or modification must ach ieve a level of continuous emissions reduction equivalent to that which would ha ve been required under section 8 by a date specified by the Secretary; 14.1.c. The source or modification would meet requi rements equivalent to all requirements of this rule that a stationary source employing a system of best available control tec hnology would be required to meet; 14.1.d. Before the date specified in subsec tion 14.4, the source or modification would: 14.1.d.1. Not cause or contribute to any violation of an applicable National Ambient Air Quality Standard; 14.1.d.2. Not impact any area where an appli cable increment is known to be violated; 14.1.d.3. Meet all other applicable requirement s including those for public participation; and 14.1.e. The provisions of 40 CFR §51.166(p) (rela ting to Class I areas) have been satisfied with respect to all periods during the life of the source or modification. 14.2. The Secretary shall consult with the governor(s) of other state(s) and the Federal Land Manager(s)

2945CSR14

of areas impacted by the proposed source or modification. 14.3. The Secretary, with the concurrence of the governor(s) of other state(s) and the Federal Land Manager(s), may make a determination that the s ource or modification would be employing innovative control technology. 14.4. The Secretary shall specify a date by which the source or modification must meet the requirements and conditions of subsection 14.1. Su ch date shall not be later than four (4) years from the time of start-up or seven (7) years from permit issuance. 14.5. The Secretary shall withdraw any approval to employ a system of innovative control technology made under this section 14 if: 14.5.a. The proposed system fails by the specified date to achieve the required continuous emissions reduction rate; or 14.5.b. The proposed system fails before the specifi ed date so as to contribute to an unreasonable risk to public health, welfare, or safety; or 14.5.c. The Secretary decides at any time that the pr oposed system is unlikely to achieve the required level of control or to protect the public health, welfare, or safety.

14.6. If the source or modification fails to meet th e required level of con tinuous emissions reduction within the specified time period, or if the approval is withdrawn in accordance with subsection 14.5, the Secretary shall specify a date by which the source or modification shall meet the requirement for the application of best available control technology through u se of a demonstrated system of control. This date shall not exceed three (3) years from the date of the e nd of the specified time period or the date that the approval is withdrawn, whichever is earlier. §45-14-15. Exclusions From Increment Consumption. 15.1. The following concentrations shall be excl uded in determining compliance with a maximum allowable increase:

15.1.a. Concentrations attributable to the incr ease in emissions from stationary sources which have converted from the use of petroleum products, natural g as, or both by reason of an order in effect under sections 2(a) and (b) of the Energy Supply and Envi ronmental Coordination Act of 1974 (or any superseding legislation as of the effective date of this rule) over the emissions from such sources before the effective date of such an order;

15.1.b. Concentrations attributable to the incr ease in emissions from sources which have converted from using natural gas by reason of natural gas curtailm ent plan in effect pursuant to the Federal Power Act over the emissions from such sources before the effective date of such plan; 15.1.c. Concentrations of particulate matter attributable to the increase in emissions from construction or other temporary emission-relate d activities of new or modified sources; and 15.1.d. Concentrations attributable to the temporary increase in emissions of sulfur dioxide,

particulate matter, or nitrogen oxides from stationary sources so long as such exclusion meets the following requirements: 15.1.d.1. The temporary emissions increase of su lfur dioxide, particulate matter or nitrogen dioxides does not exceed two (2) years in duration; 15.1.d.2. The exclusion period for the temporary emissions increase is not renewable; and 15.1.d.3. The exclusion allows no emissions increases from a stationary source which would: 15.1.d.3.A. Impact a Class I area or an area where an applicable increment is known to be violated; or 15.1.d.3.B. Cause or contribute to a violation of a National Ambient Air Quality Standard. 15.1.d.4. The exclusion requires limitations to be in effect at the end of the exclusion period specified in paragraph 15.1.d.1, which ensures that the emissions levels from stationary sources would not exceed those levels occurring from such sources before the temporary increase. 15.2. No exclusion of such concentrations shall apply more than five (5) years after the effective date of the order to which subdivision 15.1.a refers or the plan to which subdivision 15.1.b refers, whichever is applicable. If both such order and plan are applicable, no such exclusion shall apply more than five (5) years after the later of such effective dates. §45-14-16. Specific Exemptions. 16.1.

EPA, 706 F.3d 428 (D.C. Cir. 2013), no exemption is available with regard to PM 2.5 .

16.8. The permitting requirements contained in subdivi sion 9.1.b do not apply to a stationary source or modification with respect to any maximum allowable increase for nitrogen oxides if the owner or operator of the source or modification submitted an applicati on for a permit to the Secretary before the provisions embodying the maximum allowable increase took effect as part of the plan and the Secretary subsequently determines that the application as subm itted before that date was complete. 16.9. The permitting requirements contained in subdivisi on 9.1.b shall not apply to a stationary source or modification with respect to any maximum allowable increase for PM 10 if: 16.9.a. The owner or operator of the source or m odification submitted an application for a permit to the Secretary before the provisions embodying the maximum allowable increases for PM 10 took effect as part of the plan, and 16.9.b. The Secretary subsequently determines that the application as submitted before that date was complete. Instead, the applicable requirements of subdi vision 9.1.b shall apply with respect to the maximum allowable increases for TSP as in effect on the date the application was submitted. 16.10. The requirements of subsection 9.1 shall not a pply to a stationary source or modification with respect to the national ambient air quality standards for PM 2.5 in effect on March 18, 2013 if: 16.10.a. The Secretary has determined a permit appli cation subject to this section to be complete on or before December 14, 2012. Instead, the requirements in subsection 9.1 shall apply with respect to the national ambient air quality standards for PM 2.5 in effect at the time the Secretary determined the permit application to be complete; or 16.10.b. The Secretary has first published before March 18, 2013 a public notice of a preliminary determination for the permit application subject to this section.

The Secretary shall suspend or revoke a permit if, after eighteen (18) months from the date of issuance the holder of the permit cannot provide the Secr etary, at the Secretary’s request, with written proof of a good faith effort that such construction, modifi cation, or relocation has commenced and remains ongoing. Such proof shall be provided not later than th irty (30) days after the Secretary’s request. 19.3. The Secretary may suspend, modify, or revoke the permit if the plans and specifications upon which the approval was based or the conditions established in the permit are not adhered to. Upon notice of the Secretary’s intent to suspend, modify or revoke a permit, the permittee may request a conference with the Secretary in accordance with the provisions of W.Va . Code §22-5-5 to show cause why the permit should not be suspended, modified or revoked. 19.4. Any owner or operator who c onstructs, modifies or relocat es any stationary source not in accordance with the application submitted pursuant to this rule or with the terms of any permit to construct, modify or relocate, or any owner or operator of a s ource subject to this rule who commences construction after the effective date of this rule without appl ying for and receiving approval hereunder, shall be subject to appropriate enforcement action. 19.5. Possession of a permit does not relieve any person of the responsibility of complying with any and all rules of the Secretary or W.Va. Code § 22-1-1 et seq. 19.6. [Reserved.] 19.7. Any person who owns or opera tes any particular source or modification which becomes a major stationary source or major modification solely by virtue of a relaxation in any limitation, enforceable by the Administrator or the Secretary, on the capacity of the source or modification otherwise to emit a pollutant (such as a restriction on hours of operation), shall become subject to the requirements of this rule as though

3545CSR14

construction had not yet commenced on the source or modification. 19.8. Except as otherwise provided in subdivision 19.8.f, the following specific provisions apply with respect to any regulated NSR pollutant emitted from proj ects at existing emissions units at a major stationary source (other than projects at a source with a PAL) in circumstances where there is a reasonable possibility, within the meaning of subdivision 19.8.f, that a project that is not a part of a major modification may result in a significant emissions increase of such pollutant, and the owner or operator elects to use the method specified in paragraphs 2.63.a.1 through 2.63.a.3 for calculating projected actual emissions. 19.8.a. Before beginning actual cons truction of the project, the owner or operator shall document and maintain a record of the following information: 19.8.a.1. A description of the proposed project; 19.8.a.2. Identification of the emissions unit(s) w hose emissions of a regulated NSR pollutant could be affected by the proposed project; and 19.8.a.3. A description of the applicability test used to determine that the proposed 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 paragraph 2.63.a.2 and an explanation for why such amount was excluded, and any netting calculations, if applicable. 19.8.b. If the emissions unit is an existing electric utility steam generating unit, before beginning actual construction, the owner or ope rator shall provide a copy of the information required under subdivision 19.8.a to the Secretary. Nothing in subdivision 19.8.b shall be construed to requi re the owner or operator of such a unit to obtain any determination from th e Secretary before beginning actual construction. 19.8.c. The owner or operator shall monitor the emi ssions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions unit identified in paragraph 19.8.a.1. The owner or operator shall calculate and maintain a r ecord of the annual emissions, in tons per year on a calendar year basis, for a period of 5 years following resumption of regular opera tions 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 of or potential to emit that regulated NSR pollutant at such emissions unit. 19.8.d. If the unit is an existing electric utility st eam generating unit, the owner or operator shall submit a report to the Secretary within 60 days after the end of each year during which records must be generated under subdivision 19.8.c setting out the unit’ s annual emissions during the calendar year that preceded submission of the report. 19.8.e. If the unit is an existing unit other than an electric utility steam generating unit, the owner or operator shall submit a report to the Secretary if the annual emissions, in tons per year, from the project identified in subdivision 19.8.a, exceed the baseline actual emissions (as documented and maintained pursuant to paragraph 19.8.a.3), by a significant amount (as defined in subsection 2.74) for that regulated NSR pollutant, and if such emissions differ from the pr econstruction projection as documented and maintained pursuant to paragraph 19.8.a.3. Such report shall be submitted to the Secretary within 60 days after the end of such year. The report shall contain the following: 19.8.e.1. The name, address and telephone num ber of the major stationary source;

3645CSR14

19.8.e.2. The annual emissions as calculated pursuant to subdivision 19.8.c; and 19.8.e.3. 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). 19.8.f. A “reasonable possibility” under subsection 19.8 occurs when the owner or operator calculates the project to result in either: 19.8.f.1. A projected actual emissions increase of at least 50 percent of the amount that is a “significant emissions increase,” as de fined under subsection 2. 75 (without reference to the amount that is a significant net emissions increase), for the regulated NSR pollutant; or 19.8.f.2. A projected actual emissions increase that, added to the amount of emissions excluded under paragraph 2.63.a.3, sums to at least 50 percent of the amount that is a “significant emissions increase,” as defined under subsection 2.75 (without reference to th e amount that is a significant net emissions increase), for the regulated NSR pollutant. For a project for which a reasonable possibility occurs only within the meaning of this paragraph, and not also within th e meaning of paragraph 19.8.f.1, then provisions under subdivisions 19.8.b through 19.8.e do not apply to the project. 19.9. The owner or operator of the source shall make available the information required to be documented and maintained pursuant to subsection 19.8 for review upon a request for inspection by the Secretary or the general public pursuant to the re quirements contained in 45CSR30. §45-14-20. Disposition of Permits. 20.1. In the event that the Secretary promulgates chang es to this rule or in the event of a redesignation of an attainment or non-attainment area (in accordance with § 107 of the CAA) prior to final disposition of a permit, the Secretary shall make final disposition of the permit application in accordance with such newly promulgated standards or redesignation. §45-14-21. Conflict with Other Permitting Rules. 21.1. For sources required to obtain a permit under th is rule, the provisions of 45CSR13 requiring a permit do not apply, so that only a single permit is required; provided, however, that: 21.1.a. The base permit application fee of $1,000 pursu ant to 45CSR22, subdivision 3.4.a shall apply to such sources in addition to other applicable fees; and 21.1.b. Any permit issued under this rule includ es conditions that ensure compliance with the provisions of 45CSR13 to the extent applicable to any regulated air po llutant (as defined in 45CSR13) not otherwise covered under this rule. 21.2. For sources that may be subject to 45CSR 13, 45CSR14 and/or 45CSR19, the more stringent provisions of each applicable rule shall apply. §45-14-22. [Reserved.] §45-14-23. [Reserved.]

§45-14-24. [Reserved]. §45-14-25. Actuals PALs. 25.1. Applicability. 25.1.a. The Secretary may approve the use of an actuals PAL for any existing major stationary source if the PAL meets the requirements in subsections 25.1 through 25.15. The term “PAL” shall mean “actuals PAL” throughout section 25. 25.1.b. Any physical change in or change in the method of operation of a major stationary source that maintains its total source-wide emissions below the PAL level, meets the requirements in subsections 25.1 through 25.15, and complies with the PAL permit: 25.1.b.1. Is not a major modification for the PAL pollutant; 25.1.b.2. Does not have to be approved through the PSD program; and 25.1.b.3. Is not subject to the provisions in s ubsection 19.4 (restrictions on relaxing enforceable emission limitations that the major stationary source u sed to avoid applicability of the major NSR program). 25.1.c. Except as provided under paragraph 25.1.b.3, a major stationary source shall continue to comply with all applicable Federal or State re quirements, emission limitations, and work practice requirements that were established prio r to the effective date of the PAL. 25.2. Definitions. -- For the purposes of this section 25, the definition in subdivision 25.2.a applies. When a term is not defined in these paragraphs, it sha ll have the meaning given in section 2 or in the CAA.

25.2.a. Allowable emissions means “allowable emi ssions” as defined in subsection 2.6, except as modified according to paragraphs 25.2.a.1 and 25.2.a.2. 25.2.a.1. The allowable emissions for any emissions unit shall be calculated considering any emission limitations that are enforceable as a practi cal matter on the emissions unit’s potential to emit. 25.2.a.2. An emissions unit’s potential to emit shall be determined using the definition in subsection 2.58, except that the word s “or enforceable as a practical matter” should be added after “federally enforceable.” 25.3. Permit application requirements. -- As part of a permit application requesting a PAL, the owner or operator of a major stationary source shall submit th e following information to the Secretary for approval: 25.3.a. A list of all emissions units at the source designated as small, significant or major based on their potential to emit. In addition, the owner or opera tor of the source shall indicate which, if any, Federal or State applicable requirements, emission limitations, or work practices apply to each unit.

25.3.b. Calculations of the baseline actual emi ssions (with supporting doc umentation). Baseline actual emissions are to include emissions associated not only with operation of the unit, but also emissions associated with startup, shutdown, and malfunction.

3845CSR14

25.3.c. The calculation procedures that the major stationary source owner or operator proposes to use to convert the monitoring system data to monthly emissions and annual emissions based on a 12-month rolling total for each month as required by subdivision 25.13.a. 25.4. General requirements for establishing PALs. 25.4.a. The Secretary is allowed to establish a PAL at a major stationary source, provided that at a minimum, the requirements in paragraphs 25.4.a.1 through 25.4.a.7 are met. 25.4.a.1. The PAL shall impose an annual emission limitation in tons per year, that is enforceable as a practical matter, for the entire major stationary source. For each month during the PAL effective period after the first 12 months of establishing a PAL, the majo r stationary source owner or operator shall show that the sum of the monthly emissions from each emissions unit under the PAL for the previous 12 consecutive months is less than the PAL (a 12-month average, rolled monthly). For each month during the first 11 months from the PAL effective date, the major stationary sour ce owner or operator shall show that the sum of the preceding monthly emissions from the PAL effective da te for each emissions unit under the PAL is less than the PAL. 25.4.a.2. The PAL shall be established in a PAL permit that meets the public participation requirements in section 17. 25.4.a.3. The PAL permit shall contain a ll the requirements of subsection 25.7. 25.4.a.4. The PAL shall include fugitive emissions, to the extent quantifiable, from all emissions units that emit or have the potential to emit the PAL pollutant at the major stationary source. 25.4.a.5. Each PAL shall regulate emissions of only one pollutant. 25.4.a.6. Each PAL shall have a PAL effective period of 10 years. 25.4.a.7. The owner or operator of the major stati onary source with a PAL shall comply with the monitoring, recordkeeping, and reporting requireme nts provided in subsections 25.12 through 25.14 for each emissions unit under the PAL through the PAL effective period. 25.4.b. At no time during or after the PAL effec tive period are emissions reductions of a PAL pollutant that occur during the PAL effective peri od creditable as decreases for purposes of offsets pursuant to 45CSR19 unless the level of the PAL is reduced by the amount of such emissions reductions and such reductions would be creditable in the absence of the PAL. 25.5. Public participation requirements for PALs. -- PALs for existing major stationary sources shall be established, renewed, or increased through a procedure th at is consistent with 45CSR13. This includes the requirement that the Secretary provide the public with notice of the proposed approval of a PAL permit and at least a 30-day period for submittal of public comment. The Secretary must address all material comments before taking final action on the permit. 25.6. Setting the 10-year actuals PAL level. 25.6.a. Except as provided in subdivision 25.6.b, actuals PAL level for a major stationary source

3945CSR14

shall be established as the sum of the baseline actual em issions (as defined in subsection 2.8) of the PAL pollutant for each emissions unit at the source; plus an amount equal to the applicable significant level for the PAL pollutant under subsection 2.74 or under the C AA, whichever is lower. When establishing the actuals PAL level, for a PAL pollutant, only one consecu tive 24-month period must be used to determine the baseline actual emissions for all existing emissions un its. However, a different consecutive 24-month period may be used for each different PAL pollutant. Emi ssions associated with units that were permanently shutdown after this 24-month period must be subtracted from the PAL level. Emissions from units on which actual construction began after the 24- month period must be added to th e PAL level in an amount equal to the potential to emit of the units. The Secretary shall specify a reduced PAL level(s) (in tons/yr) in the PAL permit to become effective on the future compliance da te(s) of any applicable Federal or State regulatory requirement(s) that the Secretary is aware of prior to issuance of the PAL permit. For instance, if the source owner or operator will be required to reduce emissions from industrial boilers in half from baseline emissions of 60 ppm NO X to a new rule limit of 30 ppm, then the permit shall contain a future effective PAL level that is equal to the current PAL level reduced by half of the original baseline emissions of such unit(s). 25.6.b. For newly constructed units (which do not include modifications to existing units) on which actual construction began after the 24-month period, in lieu of adding the baseline actual emissions as specified in subdivision 25.6.a, the emissions must be added to the PAL level in an amount equal to the potential to emit of the units. 25.7. Contents of the PAL permit. -- The PAL permit must contain, at a minimum, the information in subdivisions 25.7.a through 25.7.j. 25.7.a. The PAL pollutant and the applicable s ource-wide emission limitation in tons per year. 25.7.b. The PAL permit effective date and the expi ration date of the PAL (PAL effective period). 25.7.c. Specification in the PAL permit that if a ma jor stationary source owner or operator applies to renew a PAL in accordance with subsection 25.10 before the end of the PAL effective period, then the PAL shall not expire at the end of the PAL effective period. It shall remain in effect until a revised PAL permit is issued by the Secretary. 25.7.d. A requirement that emission calculations for compliance purposes must include emissions from startups, shutdowns, and malfunctions. 25.7.e. A requirement that, once the PAL expires, the major stationary source is subject to the requirements of subsection 25.9. 25.7.f. The calculation procedures that the major st ationary source owner or operator shall use to convert the monitoring system data to monthly emi ssions and annual emissions based on a 12-month rolling total as required by subdivision 25.13.a. 25.7.g. A requirement that the major stationary s ource owner or operator monitor all emissions units in accordance with the provisions under subsection 25.12. 25.7.h. A requirement to retain the records requi red under subsection 25.13 on site. Such records may be retained in an electronic format.

4045CSR14

25.7.i. A requirement to submit the reports required under subsection 25.14 by the required deadlines. 25.7.j. Any other requirements that the Secretar y deems necessary to implement and enforce the PAL. 25.8. PAL effective period and reopening of the PAL permit. -- The requirements in subdivisions 25.8.a and 25.8.b apply to actuals PALs. 25.8.a. PAL effective period. -- The Secretary shall specify a PAL effective period of 10 years. 25.8.b. Reopening of the PAL permit. 25.8.b.1. During the PAL effective period, the Secretary must reopen the PAL permit to: 25.8.b.1.A. Correct typographical or calculation e rrors made in setting the PAL or reflect a more accurate determination of emissions used to establish the PAL; 25.8.b.1.B. Reduce the PAL if the owner or operator of the major stationary source creates creditable emissions reductions for use as offsets pursuant to 45CSR19; and

25.8.b.1.C. Revise the PAL to reflect an in crease in the PAL as provided under subsection 25.11. 25.8.b.2. The Secretary shall have discretion to reopen the PAL permit for the following: 25.8.b.2.A. Reduce the PAL to reflect newly a pplicable Federal requirements (for example, NSPS) with compliance dates after the PAL effective date; 25.8.b.2.B. Reduce the PAL consistent with any other requirement, that is enforceable as a practical matter, and that the State may impose on the major stationary source under the State Implementation Plan; and 25.8.b.2.C. Reduce the PAL if the Secretary de termines that a reduction is necessary to avoid causing or contributing to a National Ambient Air Quality Standard (NAAQS) or PSD increment violation, or to an adverse impact on an air quality related valu e that has been identified for a Federal Class I area by a Federal Land Manager and for which inform ation is available to the general public. 25.8.b.3. Except for the permit reopening in subparagraph 25.8.b.1.A for the correction of typographical/calculation errors that do not increase the PAL level, all other reope nings shall be carried out in accordance with the public participation requirements of subsection 25.5. 25.9. Expiration of a PAL. -- Any PAL that is not renewed in accordance with the procedures in subsection 25.10 shall expire at the end of the PAL effective period, and the requirements in subdivisions 25.9.a through 25.9.e shall apply. 25.9.a. Each emissions unit (or each group of emissions units) that existed under the PAL shall comply with an allowable emission limitation under a revised permit established according to the procedures

4145CSR14

in paragraphs 25.9.a.1 and 25.9.a.2. 25.9.a.1. Within the time frame specified for PAL renewals in subdivision 25.10.b, the major stationary source shall submit a proposed allowable emission limitation for each em issions unit (or each group of emissions units, if such a distribution is more appropriate as decided by the Secretary) by distributing the PAL allowable emissions for the major stationary sour ce among each of the emissions units that existed under the PAL. If the PAL had not yet been adjusted for an applicable requirement that became effective during the PAL effective period, as required under subdivision 25.10. e, such distribution shall be made as if the PAL had been adjusted. 25.9.a.2. The Secretary shall decide whether and how the PAL allowa ble emissions will be distributed and issue a revised permit incorporating allowable limits for each emissions unit, or each group of emissions units, as the Secretary determines is appropriate. 25.9.b. Each emissions unit(s) shall comply with the allowable emission limitation on a 12-month rolling basis. The Secretary may approve the use of monitoring systems (source testing, emission factors, etc.) other than CEMS, CERMS, PEMS, or CPMS to demonstrate compliance with the allowable emission limitation. 25.9.c. Until the Secretary issues the revised permit incorporating allowable limits for each emissions unit, or each group of emissions units, as required under paragraph 25.9.a.2, the source shall continue to comply with a source-wide, multi-unit emissi ons cap equivalent to the level of the PAL emission limitation. 25.9.d. Any physical change or change in the met hod of operation at the major stationary source will be subject to major NSR requirements if such change meets the definition of major modification in subsection 2.40. 25.9.e. The major stationary source owner or operato r shall continue to comply with any State or Federal applicable requirements (BACT, RACT, NSPS, etc.) that may have applied either during the PAL effective period or prior to the PAL effective peri od except for those emission limitations that had been established pursuant to subsection 19.4, but were elim inated by the PAL in acco rdance with the provisions in paragraph 25.1.b.3. 25.10. Renewal of a PAL. -- The Secretary shall fo llow the procedures specified in subsection 25.5 in approving any request to renew a PAL for a major stati onary source, and shall provide both the proposed PAL level and a written rationale for the proposed PAL leve l to the public for review and comment. During such public review, any person may propose a PAL level fo r the source for consideration by the Secretary. 25.10.a. Application deadline. -- A major stationary source owner or operator shall submit a timely application to the Secretary to request renewal of a PAL. A timely application is one that is submitted at least 6 months prior to, but not earlier than 18 months from, the date of permit expiration. This deadline for application submittal is to ensure that the permit will not expire before the permit is renewed. If the owner or operator of a major stationary source submits a comp lete application to renew the PAL within this time period, then the PAL shall continue to be effective until the revised permit with the renewed PAL is issued. 25.10.b. Application requirements. -- The applica tion to renew a PAL permit shall contain the information required in paragr aphs 25.10.c.1 through 25.10.c.4.

4245CSR14

25.10.b.1. The information required in subdivisions 25.3.a through 25.3.c. 25.10.b.2. A proposed PAL level. 25.10.b.3. The sum of the potential to emit of all emissions units under the PAL (with supporting documentation). 25.10.b.4. Any other information the owner or operator wishes the Secretary to consider in determining the appropriate level for renewing the PAL. 25.10.c. PAL adjustment. -- In determining whether a nd how to adjust the PAL, the Secretary shall consider the options outlined in paragraphs 25.10. d.1 and 25.10.d.2. However, in no case may any such adjustment fail to comply with paragraph 25.10.d.3. 25.10.c.1. If the emissions level calculated in accordance with subsection 25.6 is equal to or greater than 80 percent of the PAL level, the Secretary may renew the PAL at the same level without considering the factors set forth in paragraph 25.10.d.2; or 25.10.c.2. The Secretary may set the PAL at a level that he or she determines to be more representative of the source's baseline actual emissions, or that he or she determines to be more appropriate considering air quality needs, advances in control tec hnology, anticipated economic growth in the area, desire to reward or encourage the source's voluntary emissions reductions, or other factors as specifically identified by the Secretary in his or her written rationale. 25.10.c.3. Notwithstanding paragr aphs 25.10.d.1 and 25.10.d.2: 25.10.c.3.A. If the potential to emit of the major stationary source is less than the PAL, the Secretary shall adjust the PAL to a level no great er than the potential to emit of the source; and 25.10.c.3.B. The Secretary shall not approve a re newed PAL level higher than the current PAL, unless the major stationary source has complied with the provisions of subsection 25.11 (increasing a PAL). 25.10.d. If the compliance date for a State or Fede ral requirement that applies to the PAL source occurs during the PAL effective period, and if the Secr etary has not already adjust ed for such requirement, the PAL shall be adjusted at the time of PAL permit re newal or title V permit renewal, whichever occurs first. 25.11. Increasing a PAL during the PAL effective period. 25.11.a. The Secretary may increase a PAL emission limitation only if the major stationary source complies with the provisions in paragraphs 25.11.a.1 and 25.11.a.2. 25.11.a.1. The owner or operator of the majo r stationary source shall submit a complete application to request an increase in the PAL limit for a PAL major modification. Such application shall identify the emissions unit(s) contributing to the incr ease in emissions so as to cause the major stationary source's emissions to equal or exceed its PAL. 25.11.a.2. As part of this application, the ma jor stationary source owner or operator shall demonstrate that the sum of the baseline actual emissions of the small emissions units, plus the sum of the

4345CSR14

baseline actual emissions of the significant and major emissions units assuming application of BACT equivalent controls, plus the sum of the allowable emi ssions of the new or modified emissions unit(s) exceeds the PAL. The level of control that would result from BACT equivalent controls on each significant or major emissions unit shall be determined by conducting a new BACT analysis at the time the application is submitted, unless the emissions unit is currently required to comply with a BACT or LAER requirement that was established within the preceding 10 years. In su ch a case, the assumed control level for that emissions unit shall be equal to the level of BACT or LAER w ith which that emissions unit must currently comply. 25.11.a.3. The owner or operator obtains a major NSR permit for all emissions unit(s) identified in paragraph 25.11.a.1, regardless of the magnitude of the emissions increase resulting from them (that is, no significant levels apply). These emissions unit(s) sh all comply with any emissions requirements resulting from the major NSR process (for exampl e, BACT), even though they have also become subject to the PAL or continue to be subject to the PAL. 25.11.a.4. The PAL permit shall require that the increased PAL level shall be effective on the day any emissions unit that is part of the PAL majo r modification becomes operational and begins to emit the PAL pollutant. 25.11.b. The Secretary shall calculate the new PA L as the sum of the allowable emissions for each modified or new emissions unit, plus the sum of th e baseline actual emissions of the significant and major emissions units (assuming application of BACT equi valent controls as determined in accordance with paragraph 25.11.a.2), plus the sum of the baselin e actual emissions of the small emissions units. 25.11.c. The PAL permit shall be revised to refl ect the increased PAL level pursuant to the public notice requirements of subsection 25.5. 25.12. Monitoring requirements for PALs. 25.12.a. General requirements. 25.12.a.1. Each PAL permit must contain enforceable requirements for the monitoring system that accurately determines plantwide emissions of the PA L pollutant in terms of mass per unit of time. Any monitoring system authorized for use in the PAL pe rmit must be based on sound science and meet generally acceptable scientific procedures for data quality and mani pulation. Additionally, the information generated by such system must meet minimum legal requirements for admissibility in a judicial proceeding to enforce the PAL permit. 25.12.a.2. The PAL monitoring system must employ one or more of the four general monitoring approaches meeting the minimum requirements set fort h in paragraphs 25.12.b.1 through 25.12.b.4 and must be approved by the Secretary. 25.12.a.3. Notwithstanding paragraph 25.12.a.2, you may also employ an alternative monitoring approach that meets paragraph 25.12.a.1 if approved by the Secretary. 25.12.a.4. Failure to use a monitoring system that meets the requirements of this rule renders the PAL invalid. 25.12.b. Minimum performance requirements for approved monitoring approaches. The following

4445CSR14

are acceptable general monitoring approaches when c onducted in accordance with the minimum requirements in subdivisions 25.12.c through 25.12.i: 25.12.b.1. Mass balance calculations for activities using coatings or solvents; 25.12.b.2. CEMS; 25.12.b.3. CPMS or PEMS; and

25.12.b.4. Emission factors.

25.12.c. Mass balance calculations. -- An owner or operator using mass balance calculations to monitor PAL pollutant emissions from activities usi ng coating or solvents shall meet the following requirements:

25.12.c.1. Provide a demonstrated means of valid ating the published content of the PAL pollutant that is contained in or created by all materials used in or at the emissions unit; 25.12.c.2. Assume that the emissions unit emits all of the PAL pollutant that is contained in or created by any raw material or fuel used in or at the emissions unit, if it cannot otherwise be accounted for in the process; and 25.12.c.3. Where the vendor of a material or fuel, which is used in or at the emissions unit, publishes a range of pollutant content from such materi al, the owner or operator must use the highest value of the range to calculate the PAL pollutant emissions unless the Secretary determines there is site-specific data or a site-specific monitoring program to support another content within the range. 25.12.d. CEMS. An owner or operator using CEMS to monitor PAL pollutant emissions shall meet the following requirements: 25.12.d.1. CEMS must comply with applicable Performance Specifications found in 40 CFR Part 60, appendix B; and 25.12.d.2. CEMS must sample, analyze and record data at least every 15 minutes while the emissions unit is operating. 25.12.e. CPMS or PEMS. An owner or operator using CPMS or PEMS to monitor PAL pollutant emissions shall meet the following requirements: 25.12.e.1. The CPMS or the PEMS must be based on current site-specific data demonstrating a correlation between the monitore d parameter(s) and the PAL polluta nt emissions across the range of operation of the emissions unit; and 25.12.e.2. Each CPMS or PEMS must sample, analyze, and record data at least every 15 minutes, or at another less frequent interval approved by th e Secretary, while the emissions unit is operating. 25.12.f. Emission factors. -- An owner or operator using emission factors to monitor PAL pollutant emissions shall meet the following requirements:

25.12.f.1. All emission factors shall be adjusted , if appropriate, to account for the degree of uncertainty or limitations in the factors' development; 25.12.f.2. The emissions unit shall operate within the designated range of use for the emission factor, if applicable; and 25.12.f.3. If technically practicable, the owner or operator of a significant emissions unit that relies on an emission factor to calculate PAL pollutant emissions shall conduct validation testing to determine a site-specific emission factor within 6 months of PAL permit issuance, unless the Secretary determines that testing is not required. 25.12.g. A source owner or operator must record and report maximum potential emissions without considering enforceable emission limitations or operati onal restrictions for an emissions unit during any period of time that there is no monitoring data, unless another method for determining emissions during such periods is specified in the PAL permit. 25.12.h. Notwithstanding the requirements in subdi visions 25.12.c through 25.12.g, where an owner or operator of an emissions unit cannot demonstrate a correlation betw een the monitored parameter(s) and the PAL pollutant emissions rate at all operating points of the emissions unit, the Secretary shall, at the time of permit issuance: 25.12.h.1. Establish default value(s) for dete rmining compliance with the PAL based on the highest potential emissions reasonably estimated at such operating point(s); or 25.12.h.2. Determine that operation of the emissi ons unit during operating conditions when there is no correlation between monitored pa rameter(s) and the PAL pollutant emissions is a violation of the PAL.

25.12.i. Re-validation. -- All data used to establis h the PAL pollutant must be re-validated through performance testing or other scientifically valid means a pproved by the Secretary. Such testing must occur at least once every 5 years after issuance of the PAL. 25.13. Recordkeeping requirements. 25.13.a. The PAL permit shall require an owner or ope rator to retain a copy of all records necessary to determine compliance with any requirement of sec tion 28 and of the PAL, including a determination of each emissions unit’s 12-month rolling total emissions , for 5 years from the date of such record. 25.13.b. The PAL permit shall require an owner or ope rator to retain a copy of the following records for the duration of the PAL effective period plus 5 years: 25.13.b.1. A copy of the PAL permit application a nd any applications for revisions to the PAL; and 25.13.b.2. Each annual certification of complian ce pursuant to title V and the data relied on in certifying the compliance. 25.14. Reporting and notification requirements. -- The owner or operator shall submit semi-annual monitoring reports and prompt devia tion reports to the Secretary in accordance with the applicable title V

operating permit program. The reports shall meet th e requirements in subdivisions 25.14.a through 25.14.c. 25.14.a. Semi-annual report. -- The semi-annual report shall be submitted to the Secretary within 30 days of the end of each reporting period. This repor t shall contain the information required in paragraphs 25.14.a.1 through 25.14.a.7.

25.14.a.1. The identification of owne r and operator and the permit number. 25.14.a.2. Total annual emissions (tons/year) based on a 12-month rolling total for each month in the reporting period recorded pursuant to subdivision 25.13.a. 25.14.a.3. All data relied upon, including, but not limited to, any Quality Assurance or Quality Control data, in calculating the monthl y and annual PAL pollutant emissions. 25.14.a.4. A list of any emissions units modified or added to the major stationary source during the preceding 6-month period. 25.14.a.5. The number, duration, and cause of any deviations or monitoring malfunctions (other than the time associated with zero and span ca libration checks), and any corrective action taken. 25.14.a.6. A notification of a shutdown of any monitoring system, whether the shutdown was permanent or temporary, the reason for the shutdown, th e anticipated date that the monitoring system will be fully operational or replaced with another monitoring system, and whether the emissions unit monitored by the monitoring system continued to operate, and the cal culation of the emissions of the pollutant or the number determined by method included in th e permit, as provided by subdivision 25.12.g. 25.14.a.7. A signed statement by the responsible official (as defined by the 45CSR30-2.38) certifying the truth, accuracy, and completeness of the information provided in the report. 25.14.b. Deviation report. -- The major stationary source owner or operator shall promptly submit reports of any deviations or exceedance of the PAL requirements, including periods where no monitoring is available. A report submitted pursuant to 45CSR30-5.1. c.3 shall satisfy this reporting requirement. The deviation reports shall be submitted within the time lim its prescribed by the appli cable program implementing 45CSR30-5.1.c.3. The reports shall contain the following information:

25.14.b.1. The identification of owner and operator and the permit number; 25.14.b.2. The PAL requirement that experienced the deviation or that was exceeded; 25.14.b.3. Emissions resulting from the deviation or the exceedance; and 25.14.b.4. A signed statement by the responsible o fficial (as defined by the applicable title V operating permit program) certifying the truth, accuracy, and completeness of the information provided in the report. 25.14.c. Re-validation results. -- The owner or opera tor shall submit to the Secretary the results of any re-validation test or method within 3 mont hs after completion of such test or method.

25.15. Transition requirements. 25.15.a. The Secretary may not issue a PAL that does not comply with the requirements in subsections 25.1 through 25.15 after the effective date of EPA approval and promulgation of a revision to the WV SIP incorporating this rule. 25.15.b. The Secretary may supersede any PAL that w as established prior to the effective date of EPA approval and promulgation of a revision to the WV SIP in corporating this rule with a PAL that complies with the requirements of subsections 25.1 through 25.15. §45-14-26. Inconsistency Between Rules. 26.1. In the event of any inconsistency between this rule and any other rule of the West Virginia Department of Environmental Protecti on, such inconsistency shall be reso lved by the determination of the Secretary and such determination shall be based upon th e application of the more stringent provision, term, condition, method or rule.
