N.M. Admin. Code § 20.2.74.320

Current through Register Vol. 35, No. 21, November 5, 2024

Section 20.2.74.320 - ACTUALS PLANTWIDE APPLICABILITY LIMITS (PALS)

A. Applicability.

(1) The department may approve the use of an actuals PAL, including for GHGs on either a mass basis or a CO₂e basis, for any existing major stationary source or any other existing GHG-only source if the PAL meets the requirements in this section. The term "PAL" shall mean "actuals PAL" throughout this section.

(2) Any physical change in or change in the method of operation of a major stationary source or a GHG-only source that maintains its total source-wide emissions below the PAL level, meets the requirements of this section, and complies with the PAL permit:

(a) is not a major modification for the PAL pollutant;

(b) does not have to be approved through the requirements of this part; and

(c) is not subject to the provisions in Subsection D of 20.2.74.300 NMAC (restrictions on relaxing enforceable emission limitations that the major stationary source used to avoid applicability of the major new source review program); and

(d) does not make GHGs subject to regulation as defined by Subsection AZ of 20.2.74.7 NMAC.

(3) Except as provided under Subparagraph (c) of Paragraph (2) of this subsection, a major stationary source or GHG-only source shall continue to comply with all applicable federal or state requirements, emission limitations, and work practice requirements that were established prior to the effective date of the PAL.

B. Definitions applicable to this section.

(1) Actuals PAL for a major stationary source means a PAL based on the baseline actual emissions (as defined in 20.2.74.7 NMAC) of all emissions units (as defined in 20.2.74.7 NMAC) at the source, that emit or have the potential to emit the PAL pollutant. For a GHG-only source, "actuals PAL" means a PAL based on the baseline actual emissions (as defined in Paragraph (13) of this subsection) of all emissions units (as defined in Paragraph (14) of this subsection) at the source, that emit or have the potential to emit GHGs.

(2) Allowable emissions means "allowable emissions" as defined in 20.2.74.7 NMAC, except as this definition is modified in accordance with the following.

(a) The allowable emissions for any emissions unit shall be calculated considering any emission limitations that are enforceable as a practical matter on the emissions unit's potential to emit.

(b) An emissions unit's potential to emit shall be determined using the definition in 20.2.74.7 NMAC, except that the words "or enforceable as a practical matter" should be added after "federally enforceable".

(3) Small emissions unit means an emissions unit that emits or has the potential to emit the PAL pollutant in an amount less than the significant level for that PAL pollutant, as defined in Subsection AW of 20.2.74.7 NMAC or in the act, whichever is lower. For a GHG PAL issued on a CO₂e basis, "small emissions unit" means an emissions unit that emits or has the potential to emit less than the amount of GHGs on a CO₂e basis defined as "significant" for the purposes of Paragraph (3) of Subsection AZ of 20.2.74.7 NMAC at the time the PAL permit is being issued.

(4) Major emissions unit means:

(a) any emissions unit that emits or has the potential to emit 100 tons per year or more of the PAL pollutant in an attainment area; or

(b) any emissions unit that emits or has the potential to emit the PAL pollutant in an amount that is equal to or greater than the major source threshold for the PAL pollutant as defined by the act for nonattainment areas; for example, in accordance with the definition of major stationary source in Section 182(c) of the act, an emissions unit would be a major emissions unit for VOC if the emissions unit is located in a serious ozone nonattainment area and it emits or has the potential to emit 50 or more tons of VOC per year; or

(c) for a GHG PAL issued on a CO₂e basis, any emissions unit that emits or has potential to emit equal to or greater than the amount of GHGs on a CO₂e basis that would be sufficient for a new source to trigger permitting requirements under Subsection AZ of 20.2.74.7 NMAC at the time the PAL permit is being issued.

(5) Plantwide applicability limitation (PAL) means an emission limitation expressed on a mass basis in tons per year, or expressed in tons per year CO₂e for a CO₂e-based GHG emission limitation, for a pollutant at a major stationary source or GHG-only source, that is enforceable as a practical matter and established source-wide in accordance with this section.

(6) PAL effective date generally means the date of issuance of the PAL permit. However, the PAL effective date for an increased PAL is the date any emissions unit that is part of the PAL major modification becomes operational and begins to emit the PAL pollutant.

(7) PAL effective period means the period beginning with the PAL effective date and ending 10 years later.

(8) PAL major modification means, notwithstanding the definitions for major modification, net emissions increase, and subject to regulation in 20.2.74.7 NMAC, any physical change in or change in the method of operation of the PAL source that causes it to emit the PAL pollutant at a level equal to or greater than the PAL.

(9) PAL permit means the major new source review permit, the minor new source review permit, or the state operating permit under a program that is approved into the plan, or the title V permit issued by the department that establishes a PAL for a major stationary source or a GHG-only source.

(10) PAL pollutant means the pollutant for which a PAL is established at a major stationary source or a GHG-only source. For a GHG-only source, the only available PAL pollutant is greenhouse gases.

(11) Significant emissions unit means an emissions unit that emits or has the potential to emit a PAL pollutant in an amount that is equal to or greater than the significant level (as defined in Subsection AW of 20.2.74.7 NMAC or in the act, whichever is lower) for that PAL pollutant, but less than the amount that would qualify the unit as a major emissions unit as defined in Paragraph (4) of this subsection. For a GHG PAL issued on a CO₂e basis, "significant emissions unit" means any emissions unit that emits or has the potential to emit GHGs on a CO₂e basis in amounts equal to or greater than the amount that would qualify the unit as a small emissions unit as defined in Paragraph (3) of this subsection, but less than the amount that would qualify the unit as a major emissions unit as defined in Subparagraph (c) of Paragraph (4) of this subsection.

(12) GHG-only source means any existing station source that emits or has the potential to emit GHGs in the amount equal to or greater than the amount of GHGs on a mass basis that would be sufficient for a new source to trigger permitting requirements for GHGs under Subsection AG of 20.2.74.7 NMAC and the amount of GHGs on a CO₂e basis that would be sufficient for a new source to trigger permitting requirements for GHGs under Subsection AZ of 20.2.74.7 NMAC at the time the PAL permit is being issued, but does not emit or have the potential to emit any other non-GHG regulated new source review pollutant at or above the applicable major source threshold. A GHG-only source may only obtain a PAL for GHG emissions under 20.2.74.320 NMAC.

(13) Baseline actual emissions for a GHG PAL means the average rate, in tons per year CO₂e or tons per year GHG, as applicable, at which the emissions unit actually emitted GHGs 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 department for a permit required under this section or by the department for a permit required by a plan, whichever is earlier. For any existing electric utility steam generating unit, "baseline actual emissions" for a GHG PAL means the average rate, in tons per year CO₂e or tons per year GHG, as applicable, at which the emissions unit actually emitted the GHGs during any consecutive 24-month period selected by the owner or operator within the 5-year period immediately preceding either the date the owner or operator begins actual construction of the project, except that the department shall allow the use of a different time period upon a determination that it is more representative of normal source operation.

(a) The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions.

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

(c) The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the stationary source must currently comply, had such stationary source been required to comply with such limitations during the consecutive 24-month period.

(d) The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual GHG emissions and for adjusting this amount if required by Subparagraphs (b) and (c) of Paragraph (13) of this subsection.

(14) Emissions unit with respect to GHGs means any part of a stationary source that emits or has the potential to emit GHGs. For purposes of this section, there are two types of emissions units as described in the following:

(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 subparagraph (a) of this paragraph.

(15) Minor source means any stationary source that does not meet the definition of major stationary source in Subsection AG of 20.2.74.7 NMAC for any pollutant at the time the PAL is issued.

C. Permit application requirements. As part of a permit application requesting a PAL, the owner or operator of a major stationary source or a GHG-only source shall submit the following information to the department for approval.

(1) 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 operator of the source shall indicate which, if any, federal or state applicable requirements, emission limitations, or work practices apply to each unit.

(2) Calculations of the baseline actual emissions (with supporting documentation). Baseline actual emissions are to include emissions associated not only with operation of the unit, but also emissions associated with startup, shutdown, and malfunction.

(3) 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 Subsection M of this section.

(4) As part of a permit application requesting a GHG PAL, the owner or operator of a major stationary source or a GHG-only source shall submit a statement by the source owner or operator that clarifies whether the source is an existing major source as defined in Paragraphs (1) and (2) of Subsection AG of 20.2.74.7 NMAC or a GHG-only source as defined in Paragraph (12) of Subsection B of this subsection.

D. General requirements for establishing PALs.

(1) The department may establish a PAL at a major stationary source or a GHG-only source, provided that at a minimum, the following requirements are met.

(a) The PAL shall impose an annual emission limitation expressed on a mass basis in tons per year, or expressed in tons per year CO₂e, that is enforceable as a practical matter, for the entire major stationary source or GHG-only source. For each month during the PAL effective period after the first 12 months of establishing a PAL, the major stationary source or GHG-only 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 source or GHG-only source owner or operator shall show that the sum of the preceding monthly emissions from the PAL effective date for each emissions unit under the PAL is less than the PAL.

(b) The PAL shall be established in a PAL permit that meets the public participation requirements in Subsection E of this section.

(c) The PAL permit shall contain all the requirements of Subsection G of this section.

(d) 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 or GHG-only source.

(e) Each PAL shall regulate emissions of only one pollutant.

(f) Each PAL shall have a PAL effective period of 10 years.

(g) The owner or operator of the major stationary source or GHG-only source with a PAL shall comply with the monitoring, recordkeeping, and reporting requirements provided in Subsections L through N of this section for each emissions unit under the PAL through the PAL effective period.

(2) At no time (during or after the PAL effective period) are emissions reductions of a PAL pollutant that occur during the PAL effective period creditable as decreases for purposes of offsets under 40 CFR 51.165(a)(3)(ii) 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.

E. Public participation requirements for PALs. PALs for existing major stationary sources or GHG-only sources shall be established, renewed, or increased, through a procedure that is consistent with 40 CFR 51.160 and 161. This includes the requirement that the department 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 department must address all material comments before taking final action on the permit.

F. Setting the 10-year actuals PAL level.

(1) Except as provided in Paragraph (2) of this subsection, the actuals PAL level for a major stationary source or GHG-only source shall be established as the sum of the baseline actual emissions (as defined in 20.2.74.7 NMAC or, for GHGs, Paragraph (13) of Subsection B of 20.2.74.320 NMAC) 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 AW of 20.2.74.7 NMAC or under the act, whichever is lower. When establishing the actuals PAL level, for a PAL pollutant, only one consecutive 24-month period must be used to determine the baseline actual emissions for all existing emissions units. However, a different consecutive 24-month period may be used for each different PAL pollutant. Emissions associated with units that were permanently shutdown after this 24-month period must be subtracted from the PAL level. The department shall specify a reduced PAL level(s) (in tons/yr) in the PAL permit to become effective on the future compliance date(s) of any applicable federal or state regulatory requirement(s) that the department 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 NOx 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).

(2) 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 Paragraph (1) of this subsection, the emissions must be added to the PAL level in an amount equal to the potential to emit of the units.

(3) For CO₂e based GHG PAL, the actuals PAL level shall be established as the sum of the GHGs baseline actual emissions (as defined in Paragraph (13) of Subsection B of 20.2.74.320 NMAC) of GHGs for each emissions unit at the source, plus an amount equal to the amount defined as "significant" on a CO₂e basis for the purposes of Subsection AZ of 20.2.74.7 NMAC at the time the PAL permit is being issued. When establishing the actuals PAL level for a CO₂e-based PAL, only one consecutive 24-month period must be used to determine the baseline actual emissions for all existing emissions units. Emissions associated with units that were permanently shut down after this 24-month period must be subtracted from the PAL level. The department shall specify a reduced PAL level (in tons per year CO₂e) in the PAL permit to become effective on the future compliance date(s) of any applicable federal or New Mexico regulatory requirement(s) that the department is aware of prior to issuance of the PAL permit.

G. Contents of the PAL permit. The PAL permit shall contain, at a minimum, the following information.

(1) The PAL pollutant and the applicable source-wide emission limitation in tons per year or tons per year CO₂e.

(2) The PAL permit effective date and the expiration date of the PAL (PAL effective period).

(3) Specification in the PAL permit that if a major stationary source or GHG-only source owner or operator applies to renew a PAL in accordance with Subsection J of this section 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 department.

(4) A requirement that emission calculations for compliance purposes include emissions from startups, shutdowns and malfunctions.

(5) A requirement that, once the PAL expires, the major stationary source or GHG-only source is subject to the requirements of Subsection I of this section.

(6) The calculation procedures that the major stationary source or GHG-only source owner or operator shall 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 Paragraph (1) of Subsection C of this section.

(7) A requirement that the major stationary source or GHG-only source owner or operator monitor all emissions units in accordance with the provisions under Subsection M of this section.

(8) A requirement to retain the records required under Subsection M of this section on site. Such records may be retained in an electronic format.

(9) A requirement to submit the reports required under Subsection N of this section by the required deadlines.

(10) Any other requirements that the department deems necessary to implement and enforce the PAL.

(11) A permit for a GHG PAL issued to a GHG-only source shall also include a statement denoting that GHG emissions at the source will not be subject to regulation under Subsection AZ of 20.2.74.7 NMAC as long as the source complies with the PAL.

H. PAL effective period and reopening of the PAL permit.

(1) PAL effective period. The PAL effective period shall be 10 years.

(2) Reopening of the PAL permit.

(a) During the PAL effective period, the department shall reopen the PAL permit to:

(i) correct typographical/calculation errors made in setting the PAL or reflect a more accurate determination of emissions used to establish the PAL;

(ii) reduce the PAL if the owner or operator of the major stationary source creates creditable emissions reductions for use as offsets under 40 CFR 51.165(a)(3)(ii); and

(iii) revise the PAL to reflect an increase in the PAL as provided under Subsection K of this section.

(b) The department may reopen the PAL permit for the following:

(i) to reduce the PAL to reflect newly applicable federal requirements (for example, NSPS) with compliance dates after the PAL effective date;

(ii) to reduce the PAL consistent with any other requirement, that is enforceable as a practical matter, and that the department may impose on the major stationary source or GHG-only source under the plan; and

(iii) to reduce the PAL if the department determines that a reduction is necessary to avoid causing or contributing to a NAAQS or PSD increment violation, or to an adverse impact on an AQRV that has been identified for a federal class I area by a federal land manager and for which information is available to the general public.

(c) Except for the permit reopening in Item (i) of Subparagraph (a) of Paragraph (2) of this subsection for the correction of typographical/calculation errors that do not increase the PAL level, all reopenings shall be carried out in accordance with the public participation requirements of Subsection E of this section.

I. Expiration of a PAL. Any PAL that is not renewed in accordance with the procedures in Subsection J of this section shall expire at the end of the PAL effective period, and the following requirements shall apply.

(1) 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 following procedures.

(a) Within the time frame specified for PAL renewals in Paragraph (2) of Subsection J of this section, the major stationary source or GHG-only source shall submit a proposed allowable emission limitation for each emissions unit (or each group of emissions units, if such a distribution is more appropriate as decided by the department) by distributing the PAL allowable emissions for the major stationary source 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 Paragraph (5) of Subsection J of this section, such distribution shall be made as if the PAL had been adjusted.

(b) The department shall decide whether and how the PAL allowable emissions will be distributed and issue a revised permit incorporating allowable limits for each emissions unit, or each group of emissions units, as the department determines is appropriate.

(2) Each emissions unit(s) shall comply with the allowable emission limitation on a 12-month rolling basis. The department 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.

(3) Until the department issues the revised permit incorporating allowable limits for each emissions unit, or each group of emissions units, as required under Subparagraph (b) of Paragraph (1) of Subsection I of this section, the source shall continue to comply with a source-wide, multi-unit emissions cap equivalent to the level of the PAL emission limitation.

(4) Any physical change or change in the method of operation at the major stationary source or GHG-only source will be subject to major new source review requirements if such change meets the definition of major modification in 20.2.74.7 NMAC.

(5) The major stationary source or GHG-only source owner or operator shall continue to comply with any New Mexico or federal applicable requirements (BACT, RACT, NSPS, etc.) that may have applied either during the PAL effective period or prior to the PAL effective period except for those emission limitations that had been established pursuant to Subsection D of 20.2.74.300 NMAC, but were eliminated by the PAL in accordance with the provisions in Subparagraph (c) of Paragraph (2) of Subsection A of this section.

J. Renewal of a PAL.

(1) The department shall follow the procedures specified in Subsection E of this section in approving any request to renew a PAL for a major stationary source or GHG-only source, and shall provide both the proposed PAL level and a written rationale for the proposed PAL level to the public for review and comment. During such public review, any person may propose a PAL level for the source for consideration by the department.

(2) Application deadline. A major stationary source or GHG-only source owner or operator shall submit a timely application to the department 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 or GHG-only source submits a complete 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.

(3) Application requirements. The application to renew a PAL permit shall contain the following information.

(a) The information required in Subsection C of this section.

(b) A proposed PAL level.

(c) The sum of the potential to emit of all emissions units under the PAL (with supporting documentation).

(d) Any other information the owner or operator wishes the department to consider in determining the appropriate level for renewing the PAL.

(4) PAL adjustment. In determining whether and how to adjust the PAL, the department shall consider the options outlined in Subparagraphs (a) and (b) of this paragraph. However, in no case may any such adjustment fail to comply with Subparagraph (c) of this paragraph.

(a) If the emissions level calculated in accordance with Subsection F of this section is equal to or greater than 80 percent of the PAL level, the department may renew the PAL at the same level without considering the factors set forth in Subparagraph (b) of this paragraph.

(b) The department may set the PAL at a level that it determines to be more representative of the source's baseline actual emissions, or that it determines to be appropriate considering air quality needs, advances in control technology, 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 department in its written rationale.

(c) Notwithstanding Subparagraphs (a) and (b) of this paragraph:

(i) if the potential to emit of the major stationary source or GHG-only source is less than the PAL, the department shall adjust the PAL to a level no greater than the potential to emit of the source; and

(ii) the department shall not approve a renewed PAL level higher than the current PAL, unless the major stationary source or GHG-only source has complied with the provisions of Subsection K of this section (increasing a PAL).

(5) If the compliance date for a state or federal requirement that applies to the PAL source occurs during the PAL effective period, and if the department has not already adjusted for such requirement, the PAL shall be adjusted at the time of PAL permit renewal or title V permit renewal, whichever occurs first.

K. Increasing a PAL during the PAL effective period.

(1) The department may increase a PAL emission limitation only if the major stationary source or GHG-only source complies with the following provisions.

(a) The owner or operator of the major stationary source or GHG-only 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 increase in emissions so as to cause the major stationary or GHG-only source's emissions to equal or exceed its PAL.

(b) As part of this application, the major stationary source or GHG-only source owner or operator shall demonstrate that the sum of the baseline actual emissions of the small emissions units, plus the sum of the baseline actual emissions of the significant and major emissions units assuming application of BACT equivalent controls, plus the sum of the allowable emissions 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 such a case, the assumed control level for that emissions unit shall be equal to the level of BACT or LAER with which that emissions unit must currently comply.

(c) The owner or operator obtains a major new source review permit for all emissions unit(s) identified in Subparagraph (a) of this paragraph, regardless of the magnitude of the emissions increase resulting from them (that is, no significant levels apply). These emissions unit(s) shall comply with any emissions requirements resulting from the major new source review process (for example, BACT), even though they have also become subject to the PAL or continue to be subject to the PAL.

(d) 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 major modification becomes operational and begins to emit the PAL pollutant.

(2) The department shall calculate the new PAL as the sum of the allowable emissions for each modified or new emissions unit, plus the sum of the baseline actual emissions of the significant and major emissions units (assuming application of BACT equivalent controls as determined in accordance with Subparagraph (b) of Paragraph (1) of this subsection), plus the sum of the baseline actual emissions of the small emissions units.

(3) The PAL permit shall be revised to reflect the increased PAL level pursuant to the public notice requirements of Subsection E of this section.

L. Monitoring requirements for PALs.

(1) General requirements.

(a) Each PAL permit must contain enforceable requirements for the monitoring system that accurately determines plantwide emissions of the PAL pollutant in terms of mass per unit of time or CO₂e per unit of time. Any monitoring system authorized for use in the PAL permit must be based on sound science and meet generally acceptable scientific procedures for data quality and manipulation. Additionally, the information generated by such system must meet minimum legal requirements for admissibility in a judicial proceeding to enforce the PAL permit.

(b) The PAL monitoring system must employ one or more of the four general monitoring approaches meeting the minimum requirements set forth in Paragraph (2) of this subsection and must be approved by the department.

(c) Notwithstanding Subparagraph (b) of this paragraph, you may also employ an alternative monitoring approach that meets Subparagraph (a) of this paragraph if approved by the department.

(d) Failure to use a monitoring system that meets the requirements of this section renders the PAL invalid.

(2) The following are acceptable general monitoring approaches when conducted in accordance with the minimum requirements in Paragraphs (3) through (9) of this subsection:

(a) mass balance calculations for activities using coatings or solvents;

(b) CEMS;

(c) CPMS or PEMS; and

(d) emission factors.

(3) Mass balance calculations. An owner or operator using mass balance calculations to monitor PAL pollutant emissions from activities using coating or solvents shall meet the following requirements:

(a) provide a demonstrated means of validating the published content of the PAL pollutant that is contained in or created by all materials used in or at the emissions unit;

(b) 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

(c) 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 material, the owner or operator must use the highest value of the range to calculate the PAL pollutant emissions unless the department determines there is site-specific data or a site-specific monitoring program to support another content within the range.

(4) CEMS. An owner or operator using CEMS to monitor PAL pollutant emissions shall meet the following requirements:

(a) CEMS must comply with applicable performance specifications found in 40 CFR Part 60, Appendix B; and

(b) CEMS must sample, analyze, and record data at least every 15 minutes while the emissions unit is operating.

(5) CPMS or PEMS. An owner or operator using CPMS or PEMS to monitor PAL pollutant emissions shall meet the following requirements:

(a) the CPMS or the PEMS must be based on current site-specific data demonstrating a correlation between the monitored parameter(s) and the PAL pollutant emissions across the range of operation of the emissions unit; and

(b) each CPMS or PEMS must sample, analyze, and record data at least every 15 minutes, or at another less frequent interval approved by the department, while the emissions unit is operating.

(6) Emission factors. An owner or operator using emission factors to monitor PAL pollutant emissions shall meet the following requirements:

(a) all emission factors shall be adjusted, if appropriate, to account for the degree of uncertainty or limitations in the factors' development;

(b) the emissions unit shall operate within the designated range of use for the emission factor, if applicable; and

(c) 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 department determines that testing is not required.

(7) A source owner or operator must record and report maximum potential emissions without considering enforceable emission limitations or operational 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.

(8) Notwithstanding the requirements in Paragraphs (3) through (7) of this subsection, where an owner or operator of an emissions unit cannot demonstrate a correlation between the monitored parameter(s) and the PAL pollutant emissions rate at all operating points of the emissions unit, the department shall, at the time of permit issuance:

(a) establish default value(s) for determining compliance with the PAL based on the highest potential emissions reasonably estimated at such operating point(s); or

(b) determine that operation of the emissions unit during operating conditions when there is no correlation between monitored parameter(s) and the PAL pollutant emissions is a violation of the PAL.

(9) Revalidation. All data used to establish the PAL pollutant must be revalidated through performance testing or other scientifically valid means approved by the department. Such testing must occur at least once every 5 years after issuance of the PAL.

M. Recordkeeping requirements.

(1) The PAL permit shall require an owner or operator to retain a copy of all records necessary to determine compliance with any requirement of this section 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.

(2) The PAL permit shall require an owner or operator to retain a copy of the following records, for the duration of the PAL effective period plus 5 years:

(a) a copy of the PAL permit application and any applications for revisions to the PAL; and

(b) each annual certification of compliance pursuant to title V and the data relied on in certifying the compliance.

N. Reporting and notification requirements. The owner or operator shall submit semi-annual monitoring reports and prompt deviation reports to the department in accordance with the applicable title V operating permit program. The reports shall meet the following requirements.

(1) Semi-annual report. The semi-annual report shall be submitted to the department within 30 days of the end of each reporting period. This report shall contain the following information:

(a) the identification of owner and operator and the permit number;

(b) total annual emissions (expressed on a mass-basis in tons per year, or expressed in tons per year CO₂e) based on a 12-month rolling total for each month in the reporting period recorded pursuant to Paragraph (1) of Subsection M of this section;
