No provision of the Texas SO2 Trading Program or exemption under § 97.905 shall be construed as exempting or excluding the owners and operators, and the designated representative, of a Texas SO2 Trading Program source or Texas SO2 Trading Program unit from compliance with any other provision of the applicable, approved State implementation plan, a federally enforceable permit, or the Clean Air Act.

(a) Unless otherwise stated, any time period scheduled, under the Texas SO2 Trading Program, to begin on the occurrence of an act or event shall begin on the day the act or event occurs.

(b) Unless otherwise stated, any time period scheduled, under the Texas SO2 Trading Program, to begin before the occurrence of an act or event shall be computed so that the period ends the day before the act or event occurs.

The administrative appeal procedures for decisions of the Administrator under the Texas SO2 Trading Program are set forth in part 78 of this chapter.

(a) The budgets for the Texas SO2 Trading Program and Supplemental Allowance Pool for the control periods in 2019 and thereafter are as follows:

(1) The Texas SO2 Trading Program budget for the control period in 2019 and each future control period is 238,395 tons.

(2) The Texas SO2 Trading Program Supplemental Allowance Pool budget for the control period in 2019 and each future control period is 10,000 tons.

(b) The variability limit for the Texas SO2 Trading Program budget for the control periods in 2021 and thereafter is 16,688 tons.

(c) The Texas SO2 Trading Program budget in paragraph (a)(1) of this section does not include any tons in the Supplemental Allowance Pool budget in paragraph (a)(2) of this section or the variability limit in paragraph (b) of this section.

(a) Allocations from the Texas SO2 Trading Program budget. (1) Except as provided in paragraph (a)(2) of this section, Texas SO2 Trading Program allowances from the Texas SO2 Trading Program budget will be allocated, for the control periods in 2019 and each year thereafter, as provided in Table 1 to this paragraph (a)(1):

(2) Notwithstanding paragraph (a)(1) of this section, if a unit provided an allocation pursuant to the table in paragraph (a)(1) of this section does not operate, starting after 2018, during the control period in two consecutive years, such unit will not be allocated the Texas SO2 Trading Program allowances provided in paragraph (a)(1) of this section for the unit for the control periods in the fifth year after the first such year and in each year after that fifth year. All Texas SO2 Trading Program allowances that would otherwise have been allocated to such unit will be transferred to the Supplemental Allowance Pool for potential allocation in accordance with § 97.912.

(b) [Reserved]

(c) Units incorrectly allocated Texas SO2 Trading Program allowances. (1) For each control period in 2019 and thereafter, if the Administrator determines that Texas SO2 Trading Program allowances were incorrectly allocated under paragraph (a) of this section, or under a provision of a SIP revision approved by the Administrator, then the Administrator will notify the designated representative of the recipient and will act in accordance with the procedures set forth in paragraphs (c)(2) through (5) of this section:

(2) Except as provided in paragraph (c)(3) or (4) of this section, the Administrator will not record such Texas SO2 Trading Program allowances under § 97.921.

(3) If the Administrator already recorded such Texas SO2 Trading Program allowances under § 97.921 and if the Administrator makes the determination under paragraph (c)(1) of this section before making deductions for the source that includes such recipient under § 97.924(b) for such control period, then the Administrator will deduct from the account in which such Texas SO2 Trading Program allowances were recorded an amount of Texas SO2 Trading Program allowances allocated for the same or a prior control period equal to the amount of such already recorded Texas SO2 Trading Program allowances. The authorized account representative shall ensure that there are sufficient Texas SO2 Trading Program allowances in such account for completion of the deduction.

(4) If the Administrator already recorded such Texas SO2 Trading Program allowances under § 97.921 and if the Administrator makes the determination under paragraph (c)(1) of this section after making deductions for the source that includes such recipient under § 97.924(b) for such control period, then the Administrator will not make any deduction to take account of such already recorded Texas SO2 Trading Program allowances.

(5) With regard to the Texas SO2 Trading Program allowances that are not recorded, or that are deducted as an incorrect allocation, in accordance with paragraphs (c)(2) and (3) of this section, the Administrator will transfer such Texas SO2 Trading Program allowances to the Supplemental Allowance Pool for potential allocation in accordance with § 97.912.

(a) For the control periods in 2019 and 2020, the Administrator will allocate Texas SO2 Trading Program allowances from the Texas SO2 Trading Program Supplemental Allowance Pool as follows:

(1) No later than February 15, 2020 and February 15, 2021, the Administrator will review all the quarterly SO2 emissions reports provided under § 97.934(d) for each Texas SO2 Trading Program unit for the previous control period. The Administrator will identify each Texas SO2 Trading Program source for which the total amount of emissions reported for the units at the source for that control period exceeds the total amount of allowances allocated to the units at the source for that control period under § 97.911 and recorded under § 97.921.

(2) For each Texas SO2 Trading Program source identified under paragraph (a)(1) of this section, the Administrator will calculate the amount by which the total amount of reported emissions for that control period exceeds the total amount of allowances allocated for that control period under § 97.911 and recorded under § 97.921.

(3)(i) For Coleto Creek (ORIS 6178), if the source is identified under paragraph (a)(1) of this section, the Administrator will allocate and record in the source's compliance account an amount of allowances from the Supplemental Allowance Pool equal to the lesser of the amount calculated for the source under paragraph (a)(2) of this section or the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section.

(ii) For any Texas SO2 Trading Program sources identified under paragraph (a)(1) of this section other than Coleto Creek (ORIS 6178), the Administrator will allocate and record allowances from the Supplemental Allowance Pool as follows:

(A) If the total for all such sources of the amounts calculated under paragraph (a)(2) of this section is less than or equal to the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section that remain after any allocation under paragraph (a)(3)(i) of this section, then the Administrator will allocate and record in the compliance account for each such source an amount of allowances from the Supplemental Allowance Pool equal to the amount calculated for the source under paragraph (a)(2) of this section.

(B) If the total for all such sources of the amounts calculated under paragraph (a)(2) of this section is greater than the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section that remain after any allocation under paragraph (a)(3)(i) of this section, then the Administrator will calculate each such source's allocation of allowances from the Supplemental Allowance Pool by dividing the amount calculated under paragraph (a)(2) of this section for the source by the sum of the amounts calculated under paragraph (a)(2) of this section for all such sources, then multiplying by the number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section that remain after any allocation under paragraph (a)(3)(i) of this section and rounding to the nearest allowance. The Administrator will adjust the sources' allocations up or down by one allowance, starting with the largest allocation and continuing in descending order, as necessary to cause the sum of the sources' allocations to equal the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section that remain after any allocation under paragraph (a)(3)(i) of this section. The Administrator will then record the calculated allocations of allowances in the applicable compliance accounts.

(iii) Any unallocated allowances remaining in the Supplemental Allowance Pool after the allocations determined under paragraphs (a)(3)(i) and (ii) of this section will be maintained in the Supplemental Allowance Pool. These allowances will be available for allocation by the Administrator in subsequent control periods to the extent consistent with paragraph (d) of this section.

(b) For each control period in 2021 and thereafter, the Administrator will allocate Texas SO2 Trading Program allowances from the Texas SO2 Trading Program Supplemental Allowance Pool as follows:

(1) For each control period, the Administrator will assign each Texas SO2 Trading Program unit to an affiliated ownership group reflecting the unit's ownership as of December 31 of the control period. The affiliated ownership group assignments for each control period will be as shown in § 97.911(a)(1) except that the Administrator will revise the assignments, based on the information required to be submitted in accordance with § 97.915(c) and any other information available to the Administrator, as necessary to reflect any ownership transfer resulting in a 50% or greater ownership share of a unit being held by a new owner that the Administrator determines is not affiliated with the previous holder of a 50% or greater ownership share of the unit.

(2) No later than May 1, 2022 and May 1 of each year thereafter, the Administrator will review all the quarterly SO2 emissions reports provided under § 97.934(d) for each Texas SO2 Trading Program unit for the previous control period. The Administrator will identify each affiliated ownership group of Texas SO2 Trading Program units as of December 31 of such control period for which the total amount of emissions reported for the units in the group for that control period exceeds the total amount of allowances allocated to the units in the group for that control period under § 97.911 and recorded under § 97.921.

(3) For each affiliated ownership group of Texas SO2 Trading Program units identified under paragraph (b)(2) of this section, the Administrator will calculate the amount by which the total amount of reported emissions for that control period exceeds the total amount of allowances allocated for that control period under § 97.911 and recorded under § 97.921.

(4)(i) The Administrator will allocate and record allowances from the Supplemental Allowance Pool as follows:

(A) If the total for all such affiliated ownership groups of the amounts calculated under paragraph (b)(3) of this section is less than or equal to the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section, then each such group's allocation of allowances from the Supplemental Allowance Pool shall equal to the amount calculated for the group under paragraph (b)(3) of this section.

(B) If the total for all such affiliated ownership groups of the amounts calculated under paragraph (b)(3) of this section is greater than the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section, then the Administrator will calculate each such group's allocation of allowances from the Supplemental Allowance Pool by dividing the amount calculated under paragraph (b)(3) of this section for the group by the sum of the amounts calculated under paragraph (b)(3) of this section for all such groups, then multiplying by the number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section and rounding to the nearest allowance. The Administrator will adjust the groups' allocations up or down by one allowance, starting with the largest allocation and continuing in descending order, as necessary to cause the sum of the groups' allocations to equal the total number of allowances in the Supplemental Allowance Pool available for allocation under paragraph (d) of this section.

(C) When an affiliated ownership group receives an allocation of allowances under paragraph (b)(4)(i)(A) or (B) of this section, each source in the group whose emissions during the control period for which allowances are being allocated exceed the amount of allowances allocated to the source under § 97.911 and recorded under § 97.921 will receive a share of the group's allocation. The Administrator will compute each such source's share by dividing the amount of the source's emissions during the control period exceeding the source's allocation under § 97.911 by the sum for all such sources of the amounts of the sources' emissions during the control period exceeding the sources' allocations under § 97.911, then multiplying by the group's allocation under paragraph (b)(4)(i)(A) or (B) of this section and rounding to the nearest allowance. The Administrator will adjust the sources' allocations up or down by one allowance, starting with the largest allocation and continuing in descending order, as necessary to cause the sum of the sources' allocations to equal the group's allocation. The Administrator will then record the calculated allocations of allowances in the applicable sources' compliance accounts.

(ii) Any unallocated allowances remaining in the Supplemental Allowance Pool after the allocations determined under paragraph (b)(4)(i) of this section will be maintained in the Supplemental Allowance Pool. These allowances will be available for allocation by the Administrator in subsequent control periods to the extent consistent with paragraph (d) of this section.

(c) The Administrator will notify the designated representative of each Texas SO2 Trading Program source when the allowances from the Supplemental Allowance Pool have been recorded.

(d) The total amount of allowances in the Supplemental Allowance Pool available for allocation for a control period is equal to the sum of the Supplemental Allowance Pool budget under § 97.910(a)(2), any allowances from retired units pursuant to § 97.911(a)(2) and from corrections pursuant to § 97.911(c)(5), and any allowances maintained in the Supplemental Allowance Pool pursuant to paragraph (a)(3)(iii) or (b)(4)(ii) of this section, provided that if the number of allowances in the Supplemental Allowance Pool exceeds the applicable limit for the control period under paragraph (d)(1) or (d)(2) of this section, then the Administrator may only allocate allowances up to such applicable limit.

(1) For the control periods in 2019 and 2020, the total amount of allowances allocated from the Supplemental Allowance Pool for a control period may not exceed by more than 44,711 tons the sum of the Supplemental Allowance Pool budget under § 97.910(a)(2) and any portion of the Texas SO2 Trading Program budget under § 97.910(a)(1) not otherwise allocated for that control period under § 97.911(a)(1).

(2) For each control period in 2021 and thereafter, the total amount of allowances allocated from the Supplemental Allowance Pool for a control period may not exceed the sum of the variability limit under § 97.910(b) and any portion of the Texas SO2 Trading Program budget under § 97.910(a)(1) not otherwise allocated for that control period under § 97.911(a)(1).

(a) Except as provided under § 97.915, each Texas SO2 Trading Program source, including all Texas SO2 Trading Program units at the source, shall have one and only one designated representative, with regard to all matters under the Texas SO2 Trading Program.

(1) The designated representative shall be selected by an agreement binding on the owners and operators of the source and all Texas SO2 Trading Program units at the source and shall act in accordance with the certification statement in § 97.916(a)(4)(iii).

(2) Upon and after receipt by the Administrator of a complete certificate of representation under § 97.916:

(i) The designated representative shall be authorized and shall represent and, by his or her representations, actions, inactions, or submissions, legally bind each owner and operator of the source and each Texas SO2 Trading Program unit at the source in all matters pertaining to the Texas SO2 Trading Program, notwithstanding any agreement between the designated representative and such owners and operators; and

(ii) The owners and operators of the source and each Texas SO2 Trading Program unit at the source shall be bound by any decision or order issued to the designated representative by the Administrator regarding the source or any such unit.

(b) Except as provided under § 97.915, each Texas SO2 Trading Program source may have one and only one alternate designated representative, who may act on behalf of the designated representative. The agreement by which the alternate designated representative is selected shall include a procedure for authorizing the alternate designated representative to act in lieu of the designated representative.

(1) The alternate designated representative shall be selected by an agreement binding on the owners and operators of the source and all Texas SO2 Trading Program units at the source and shall act in accordance with the certification statement in § 97.916(a)(4)(iii).

(2) Upon and after receipt by the Administrator of a complete certificate of representation under § 97.916,

(i) The alternate designated representative shall be authorized;

(ii) Any representation, action, inaction, or submission by the alternate designated representative shall be deemed to be a representation, action, inaction, or submission by the designated representative; and

(iii) The owners and operators of the source and each Texas SO2 Trading Program unit at the source shall be bound by any decision or order issued to the alternate designated representative by the Administrator regarding the source or any such unit.

(c) Except in this section, § 97.902, and §§ 97.914 through 97.918, whenever the term “designated representative” (as distinguished from the term “common designated representative”) is used in this subpart, the term shall be construed to include the designated representative or any alternate designated representative.

(a) Except as provided under § 97.918 concerning delegation of authority to make submissions, each submission under the Texas SO2 Trading Program shall be made, signed, and certified by the designated representative or alternate designated representative for each Texas SO2 Trading Program source and Texas SO2 Trading Program unit for which the submission is made. Each such submission shall include the following certification statement by the designated representative or alternate designated representative: “I am authorized to make this submission on behalf of the owners and operators of the source or units for which the submission is made. I certify under penalty of law that I have personally examined, and am familiar with, the statements and information submitted in this document and all its attachments. Based on my inquiry of those individuals with primary responsibility for obtaining the information, I certify that the statements and information are to the best of my knowledge and belief true, accurate, and complete. I am aware that there are significant penalties for submitting false statements and information or omitting required statements and information, including the possibility of fine or imprisonment.”

(b) The Administrator will accept or act on a submission made for a Texas SO2 Trading Program source or a Texas SO2 Trading Program unit only if the submission has been made, signed, and certified in accordance with paragraph (a) of this section and § 97.918.

(a) Changing designated representative. The designated representative may be changed at any time upon receipt by the Administrator of a superseding complete certificate of representation under § 97.916. Notwithstanding any such change, all representations, actions, inactions, and submissions by the previous designated representative before the time and date when the Administrator receives the superseding certificate of representation shall be binding on the new designated representative and the owners and operators of the Texas SO2 Trading Program source and the Texas SO2 Trading Program units at the source.

(b) Changing alternate designated representative. The alternate designated representative may be changed at any time upon receipt by the Administrator of a superseding complete certificate of representation under § 97.916.

(c) Changes in owners and operators. (1) In the event an owner or operator of a Texas SO2 Trading Program source or a Texas SO2 Trading Program unit at the source is not included in the list of owners and operators in the certificate of representation under § 97.916, such owner or operator shall be deemed to be subject to and bound by the certificate of representation, the representations, actions, inactions, and submissions of the designated representative and any alternate designated representative of the source or unit, and the decisions and orders of the Administrator, as if the owner or operator were included in such list.

(2) Within 30 days after any change in the owners and operators of a Texas SO2 Trading Program source or a Texas SO2 Trading Program unit at the source, including the addition or removal of an owner or operator, the designated representative or any alternate designated representative shall submit a revision to the certificate of representation under § 97.916 amending the list of owners and operators to reflect the change.

(1) A decision not to record the transfer, and

(2) The reasons for such non-recordation.

(a) Availability for deduction for compliance. Texas SO2 Trading Program allowances are available to be deducted for compliance with a source's Texas SO2 Trading Program emissions limitation for a control period in a given year only if the Texas SO2 Trading Program allowances:

(1) Were allocated for such control period or a control period in a prior year; and

(2) Are held in the source's compliance account as of the allowance transfer deadline for such control period.

(b) Deductions for compliance. After the recordation, in accordance with § 97.923, of Texas SO2 Trading Program allowance transfers submitted by the allowance transfer deadline for a control period in a given year, the Administrator will deduct from each source's compliance account Texas SO2 Trading Program allowances available under paragraph (a) of this section in order to determine whether the source meets the Texas SO2 Trading Program emissions limitation for such control period, as follows:

(1) Until the amount of Texas SO2 Trading Program allowances deducted equals the number of tons of total SO2 emissions from all Texas SO2 Trading Program units at the source for such control period; or

(2) If there are insufficient Texas SO2 Trading Program allowances to complete the deductions in paragraph (b)(1) of this section, until no more Texas SO2 Trading Program allowances available under paragraph (a) of this section remain in the compliance account.

(c) Selection of Texas SO2 Trading Program allowances for deduction—(1) Identification by serial number. The designated representative for a source may request that specific Texas SO2 Trading Program allowances, identified by serial number, in the source's compliance account be deducted for emissions or excess emissions for a control period in a given year in accordance with paragraph (b) or (d) of this section. In order to be complete, such request shall be submitted to the Administrator by the allowance transfer deadline for such control period and include, in a format prescribed by the Administrator, the identification of the Texas SO2 Trading Program source and the appropriate serial numbers.

(2) First-in, first-out. The Administrator will deduct Texas SO2 Trading Program allowances under paragraph (b) or (d) of this section from the source's compliance account in accordance with a complete request under paragraph (c)(1) of this section or, in the absence of such request or in the case of identification of an insufficient amount of Texas SO2 Trading Program allowances in such request, on a first-in, first-out accounting basis in the following order:

(i) Any Texas SO2 Trading Program allowances that were recorded in the compliance account pursuant to § 97.921 and not transferred out of the compliance account, in the order of recordation; and then

(ii) Any other Texas SO2 Trading Program allowances that were transferred to and recorded in the compliance account pursuant to this subpart, in the order of recordation.

(d) Deductions for excess emissions. After making the deductions for compliance under paragraph (b) of this section for a control period in a year in which the Texas SO2 Trading Program source has excess emissions, the Administrator will deduct from the source's compliance account an amount of Texas SO2 Trading Program allowances, allocated for a control period in a prior year or the control period in the year of the excess emissions or in the immediately following year, equal to three times the number of tons of the source's excess emissions.

(e) Recordation of deductions. The Administrator will record in the appropriate compliance account all deductions from such an account under paragraphs (b) and (d) of this section.

(a) Availability for deduction. Texas SO2 Trading Program allowances are available to be deducted for compliance with the Texas SO2 Trading Program assurance provisions for a control period in a given year by the owners and operators of a group of one or more Texas SO2 Trading Program sources and units only if the Texas SO2 Trading Program allowances:

(1) Were allocated for a control period in a prior year or the control period in the given year or in the immediately following year; and

(2) Are held in the assurance account, established by the Administrator for such owners and operators of such group of Texas SO2 Trading Program sources and units under paragraph (b)(3) of this section, as of the deadline established in paragraph (b)(4) of this section.

(b) Deductions for compliance. The Administrator will deduct Texas SO2 Trading Program allowances available under paragraph (a) of this section for compliance with the Texas SO2 Trading Program assurance provisions for a control period in a given year in accordance with the following procedures:

(1) By August 1, 2022 and August 1 of each year thereafter, the Administrator will:

(i) Calculate the total SO2 emissions from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources during the control period in the year before the year of this calculation deadline and the amount, if any, by which such total SO2 emissions exceed the State assurance level as described in § 97.906(c)(2)(iii); and

(ii) If the results of the calculations required in paragraph (b)(1)(i) of this section indicate that total SO2 emissions exceed the State assurance level for such control period—

(A) Calculate, for such control period and each common designated representative for such control period for a group of one or more Texas SO2 Trading Program sources and units, the common designated representative's share of the total SO2 emissions from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources, the common designated representative's assurance level, and the amount (if any) of Texas SO2 Trading Program allowances that the owners and operators of such group of sources and units must hold in accordance with the calculation formula in § 97.906(c)(2)(i); and

(B) Promulgate a notice of data availability of the results of the calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this section, including separate calculations of the SO2 emissions from each Texas SO2 Trading Program source.

(2) The Administrator will provide an opportunity for submission of objections to the calculations referenced by each notice of data availability required in paragraph (b)(1)(ii) of this section.

(i) Objections shall be submitted by the deadline specified in such notice and shall be limited to addressing whether the calculations referenced in such notice are in accordance with § 97.906(c)(2)(iii), §§ 97.906(b) and 97.930 through 97.935, the definitions of “common designated representative”, “common designated representative's assurance level”, and “common designated representative's share” in § 97.902, and the calculation formula in § 97.906(c)(2)(i).

(ii) The Administrator will adjust the calculations to the extent necessary to ensure that they are in accordance with the provisions referenced in paragraph (b)(2)(i) of this section. By October 1 immediately after the promulgation of such notice, the Administrator will promulgate a notice of data availability of the results of the calculations incorporating any adjustments that the Administrator determines to be necessary and the reasons for accepting or rejecting any objections submitted in accordance with paragraph (b)(2)(i) of this section.

(3) The Administrator will establish one assurance account for each set of owners and operators referenced, in each notice of data availability required under paragraph (b)(2)(ii) of this section, as all of the owners and operators of a group of Texas SO2 Trading Program sources and units having a common designated representative for such control period and as being required to hold Texas SO2 Trading Program allowances.

(4)(i) As of midnight of November 1 immediately after the promulgation of each notice of data availability required in paragraph (b)(2)(ii) of this section, the owners and operators described in paragraph (b)(3) of this section shall hold in the assurance account established for them and for the appropriate Texas SO2 Trading Program sources and Texas SO2 Trading Program units under paragraph (b)(3) of this section a total amount of Texas SO2 Trading Program allowances, available for deduction under paragraph (a) of this section, equal to the amount such owners and operators are required to hold with regard to such sources and units as calculated by the Administrator and referenced in such notice.

(ii) Notwithstanding the allowance-holding deadline specified in paragraph (b)(4)(i) of this section, if November 1 is not a business day, then such allowance-holding deadline shall be midnight of the first business day thereafter.

(5) After November 1 (or the date described in paragraph (b)(4)(ii) of this section) immediately after the promulgation of each notice of data availability required in paragraph (b)(2)(ii) of this section and after the recordation, in accordance with § 97.923, of Texas SO2 Trading Program allowance transfers submitted by midnight of such date, the Administrator will determine whether the owners and operators described in paragraph (b)(3) of this section hold, in the assurance account for the appropriate Texas SO2 Trading Program sources and Texas SO2 Trading Program units established under paragraph (b)(3) of this section, the amount of Texas SO2 Trading Program allowances available under paragraph (a) of this section that the owners and operators are required to hold with regard to such sources and units as calculated by the Administrator and referenced in the notice required in paragraph (b)(2)(ii) of this section.

(6) Notwithstanding any other provision of this subpart and any revision, made by or submitted to the Administrator after the promulgation of the notice of data availability required in paragraph (b)(2)(ii) of this section for a control period in a given year, of any data used in making the calculations referenced in such notice, the amounts of Texas SO2 Trading Program allowances that the owners and operators are required to hold in accordance with § 97.906(c)(2)(i) for such control period shall continue to be such amounts as calculated by the Administrator and referenced in such notice required in paragraph (b)(2)(ii) of this section, except as follows:

(i) If any such data are revised by the Administrator as a result of a decision in or settlement of litigation concerning such data on appeal under part 78 of this chapter of such notice, or on appeal under section 307 of the Clean Air Act of a decision rendered under part 78 of this chapter on appeal of such notice, then the Administrator will use the data as so revised to recalculate the amounts of Texas SO2 Trading Program allowances that owners and operators are required to hold in accordance with the calculation formula in § 97.906(c)(2)(i) for such control period with regard to the Texas SO2 Trading Program sources and Texas SO2 Trading Program units involved, provided that such litigation under part 78 of this chapter, or the proceeding under part 78 of this chapter that resulted in the decision appealed in such litigation under section 307 of the Clean Air Act, was initiated no later than 30 days after promulgation of such notice required in paragraph (b)(2)(ii) of this section.

(ii) [Reserved]

(iii) If the revised data are used to recalculate, in accordance with paragraph (b)(6)(i) of this section, the amount of Texas SO2 Trading Program allowances that the owners and operators are required to hold for such control period with regard to the Texas SO2 Trading Program sources and Texas SO2 Trading Program units involved—

(A) Where the amount of Texas SO2 Trading Program allowances that the owners and operators are required to hold increases as a result of the use of all such revised data, the Administrator will establish a new, reasonable deadline on which the owners and operators shall hold the additional amount of Texas SO2 Trading Program allowances in the assurance account established by the Administrator for the appropriate Texas SO2 Trading Program sources and Texas SO2 Trading Program units under paragraph (b)(3) of this section. The owners' and operators' failure to hold such additional amount, as required, before the new deadline shall not be a violation of the Clean Air Act. The owners' and operators' failure to hold such additional amount, as required, as of the new deadline shall be a violation of the Clean Air Act. Each Texas SO2 Trading Program allowance that the owners and operators fail to hold as required as of the new deadline, and each day in such control period, shall be a separate violation of the Clean Air Act.

(B) For the owners and operators for which the amount of Texas SO2 Trading Program allowances required to be held decreases as a result of the use of all such revised data, the Administrator will record, in all accounts from which Texas SO2 Trading Program allowances were transferred by such owners and operators for such control period to the assurance account established by the Administrator for the appropriate Texas SO2 Trading Program sources and Texas SO2 Trading Program units under paragraph (b)(3) of this section, a total amount of the Texas SO2 Trading Program allowances held in such assurance account equal to the amount of the decrease. If Texas SO2 Trading Program allowances were transferred to such assurance account from more than one account, the amount of Texas SO2 Trading Program allowances recorded in each such transferor account will be in proportion to the percentage of the total amount of Texas SO2 Trading Program allowances transferred to such assurance account for such control period from such transferor account.

(C) Each Texas SO2 Trading Program allowance held under paragraph (b)(6)(iii)(A) of this section as a result of recalculation of requirements under the Texas SO2 Trading Program assurance provisions for such control period must be a Texas SO2 Trading Program allowance allocated for a control period in a year before or the year immediately following, or in the same year as, the year of such control period.

(a) A Texas SO2 Trading Program allowance may be banked for future use or transfer in a compliance account or general account in accordance with paragraph (b) of this section.

(b) Any Texas SO2 Trading Program allowance that is held in a compliance account or a general account will remain in such account unless and until the Texas SO2 Trading Program allowance is deducted or transferred under § 97.911(c), § 97.923, § 97.924, § 97.925, § 97.927, or § 97.928.

The Administrator may, at his or her sole discretion and on his or her own motion, correct any error in any Allowance Management System account. Within 10 business days of making such correction, the Administrator will notify the authorized account representative for the account.

(a) The Administrator may review and conduct independent audits concerning any submission under the Texas SO2 Trading Program and make appropriate adjustments of the information in the submission.

(b) The Administrator may deduct Texas SO2 Trading Program allowances from or transfer Texas SO2 Trading Program allowances to a compliance account or an assurance account, based on the information in a submission, as adjusted under paragraph (a) of this section, and record such deductions and transfers.

(2) Requirements for recertification. Whenever the owner or operator makes a replacement, modification, or change in any certified continuous emission monitoring system under § 97.930(a)(1) that may significantly affect the ability of the system to accurately measure or record SO2 mass emissions or heat input rate or to meet the quality-assurance and quality-control requirements of § 75.21 of this chapter or appendix B to part 75 of this chapter, the owner or operator shall recertify the monitoring system in accordance with § 75.20(b) of this chapter. Furthermore, whenever the owner or operator makes a replacement, modification, or change to the flue gas handling system or the unit's operation that may significantly change the stack flow or concentration profile, the owner or operator shall recertify each continuous emission monitoring system whose accuracy is potentially affected by the change, in accordance with § 75.20(b) of this chapter. Examples of changes to a continuous emission monitoring system that require recertification include replacement of the analyzer, complete replacement of an existing continuous emission monitoring system, or change in location or orientation of the sampling probe or site. Any fuel flowmeter system under § 97.930(a)(1) is subject to the recertification requirements in § 75.20(g)(6) of this chapter.

(3) Approval process for initial certification and recertification. For initial certification of a continuous monitoring system under § 97.930(a)(1), paragraphs (d)(3)(i) through (v) of this section apply. For recertifications of such monitoring systems, paragraphs (d)(3)(i) through (iv) of this section and the procedures in § 75.20(b)(5) and (g)(7) of this chapter (in lieu of the procedures in paragraph (d)(3)(v) of this section) apply, provided that in applying paragraphs (d)(3)(i) through (iv) of this section, the words “certification” and “initial certification” are replaced by the word “recertification” and the word “certified” is replaced by the word “recertified”.

(i) Notification of certification. The designated representative shall submit to the appropriate EPA Regional Office and the Administrator written notice of the dates of certification testing, in accordance with § 97.933.

(ii) Certification application. The designated representative shall submit to the Administrator a certification application for each monitoring system. A complete certification application shall include the information specified in § 75.63 of this chapter.

(iii) Provisional certification date. The provisional certification date for a monitoring system shall be determined in accordance with § 75.20(a)(3) of this chapter. A provisionally certified monitoring system may be used under the Texas SO2 Trading Program for a period not to exceed 120 days after receipt by the Administrator of the complete certification application for the monitoring system under paragraph (d)(3)(ii) of this section. Data measured and recorded by the provisionally certified monitoring system, in accordance with the requirements of part 75 of this chapter, will be considered valid quality-assured data (retroactive to the date and time of provisional certification), provided that the Administrator does not invalidate the provisional certification by issuing a notice of disapproval within 120 days of the date of receipt of the complete certification application by the Administrator.

(iv) Certification application approval process. The Administrator will issue a written notice of approval or disapproval of the certification application to the owner or operator within 120 days of receipt of the complete certification application under paragraph (d)(3)(ii) of this section. In the event the Administrator does not issue such a notice within such 120-day period, each monitoring system that meets the applicable performance requirements of part 75 of this chapter and is included in the certification application will be deemed certified for use under the Texas SO2 Trading Program.

(A) Approval notice. If the certification application is complete and shows that each monitoring system meets the applicable performance requirements of part 75 of this chapter, then the Administrator will issue a written notice of approval of the certification application within 120 days of receipt.

(B) Incomplete application notice. If the certification application is not complete, then the Administrator will issue a written notice of incompleteness that sets a reasonable date by which the designated representative must submit the additional information required to complete the certification application. If the designated representative does not comply with the notice of incompleteness by the specified date, then the Administrator may issue a notice of disapproval under paragraph (d)(3)(iv)(C) of this section.

(C) Disapproval notice. If the certification application shows that any monitoring system does not meet the performance requirements of part 75 of this chapter or if the certification application is incomplete and the requirement for disapproval under paragraph (d)(3)(iv)(B) of this section is met, then the Administrator will issue a written notice of disapproval of the certification application. Upon issuance of such notice of disapproval, the provisional certification is invalidated by the Administrator and the data measured and recorded by each uncertified monitoring system shall not be considered valid quality-assured data beginning with the date and hour of provisional certification (as defined under § 75.20(a)(3) of this chapter).

(D) Audit decertification. The Administrator may issue a notice of disapproval of the certification status of a monitor in accordance with § 97.932(b).

(v) Procedures for loss of certification. If the Administrator issues a notice of disapproval of a certification application under paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of certification status under paragraph (d)(3)(iv)(D) of this section, then:

(A) The owner or operator shall substitute the following values, for each disapproved monitoring system, for each hour of unit operation during the period of invalid data specified under § 75.20(a)(4)(iii), § 75.20(g)(7), or § 75.21(e) of this chapter and continuing until the applicable date and hour specified under § 75.20(a)(5)(i) or (g)(7) of this chapter:

(1) For a disapproved SO2 pollutant concentration monitor and disapproved flow monitor, respectively, the maximum potential concentration of SO2 and the maximum potential flow rate, as defined in sections 2.1.1.1 and 2.1.4.1 of appendix A to part 75 of this chapter.

(2) For a disapproved moisture monitoring system and disapproved diluent gas monitoring system, respectively, the minimum potential moisture percentage and either the maximum potential CO2 concentration or the minimum potential O2 concentration (as applicable), as defined in sections 2.1.5, 2.1.3.1, and 2.1.3.2 of appendix A to part 75 of this chapter.

(3) For a disapproved fuel flowmeter system, the maximum potential fuel flow rate, as defined in section 2.4.2.1 of appendix D to part 75 of this chapter.

(B) The designated representative shall submit a notification of certification retest dates and a new certification application in accordance with paragraphs (d)(3)(i) and (ii) of this section.

(C) The owner or operator shall repeat all certification tests or other requirements that were failed by the monitoring system, as indicated in the Administrator's notice of disapproval, no later than 30 unit operating days after the date of issuance of the notice of disapproval.

(e) The owner or operator of a unit qualified to use the low mass emissions (LME) excepted methodology under § 75.19 of this chapter shall meet the applicable certification and recertification requirements in §§ 75.19(a)(2) and 75.20(h) of this chapter. If the owner or operator of such a unit elects to certify a fuel flowmeter system for heat input determination, the owner or operator shall also meet the certification and recertification requirements in § 75.20(g) of this chapter.

(f) The designated representative of each unit for which the owner or operator intends to use an alternative monitoring system approved by the Administrator under subpart E of part 75 of this chapter shall comply with the applicable notification and application procedures of § 75.20(f) of this chapter.

(a) General provisions. Whenever any monitoring system fails to meet the quality-assurance and quality-control requirements or data validation requirements of part 75 of this chapter, data shall be substituted using the applicable missing data procedures in subpart D of, or appendix D to, part 75 of this chapter.

(b) Audit decertification. Whenever both an audit of a monitoring system and a review of the initial certification or recertification application reveal that any monitoring system should not have been certified or recertified because it did not meet a particular performance specification or other requirement under § 97.931 or the applicable provisions of part 75 of this chapter, both at the time of the initial certification or recertification application submission and at the time of the audit, the Administrator will issue a notice of disapproval of the certification status of such monitoring system. For the purposes of this paragraph, an audit shall be either a field audit or an audit of any information submitted to the Administrator or any State or permitting authority. By issuing the notice of disapproval, the Administrator revokes prospectively the certification status of the monitoring system. The data measured and recorded by the monitoring system shall not be considered valid quality-assured data from the date of issuance of the notification of the revoked certification status until the date and time that the owner or operator completes subsequently approved initial certification or recertification tests for the monitoring system. The owner or operator shall follow the applicable initial certification or recertification procedures in § 97.931 for each disapproved monitoring system.

The designated representative of a Texas SO2 Trading Program unit shall submit written notice to the Administrator in accordance with § 75.61 of this chapter.

(a) General provisions. The designated representative of a Texas SO2 Trading Program unit shall comply with all recordkeeping and reporting requirements in paragraphs (b) through (e) of this section, the applicable recordkeeping and reporting requirements in subparts F and G of part 75 of this chapter, and the requirements of § 97.914(a).

(b) Monitoring plans. The owner or operator of a Texas SO2 Trading Program unit shall comply with the requirements of § 75.62 of this chapter.

(c) Certification applications. The designated representative shall submit an application to the Administrator within 45 days after completing all initial certification or recertification tests required under § 97.931, including the information required under § 75.63 of this chapter.

(d) Quarterly reports. The designated representative shall submit quarterly reports, as follows:

(1) The designated representative shall report the SO2 mass emissions data and heat input data for a Texas SO2 Trading Program unit, in an electronic quarterly report in a format prescribed by the Administrator, for each calendar quarter beginning with the calendar quarter covering January 1, 2019 through March 31, 2019.

(2) The designated representative shall submit each quarterly report to the Administrator within 30 days after the end of the calendar quarter covered by the report. Quarterly reports shall be submitted in the manner specified in § 75.64 of this chapter.

(3) For Texas SO2 Trading Program units that are also subject to the Acid Rain Program, CSAPR NOX Ozone Season Group 2 Trading Program, or CSAPR NOX Ozone Season Group 3 Trading Program, quarterly reports shall include the applicable data and information required by subparts F through H of part 75 of this chapter as applicable, in addition to the SO2 mass emission data, heat input data, and other information required by this subpart.

(4) The Administrator may review and conduct independent audits of any quarterly report in order to determine whether the quarterly report meets the requirements of this subpart and part 75 of this chapter, including the requirement to use substitute data.

(i) The Administrator will notify the designated representative of any determination that the quarterly report fails to meet any such requirements and specify in such notification any corrections that the Administrator believes are necessary to make through resubmission of the quarterly report and a reasonable time period within which the designated representative must respond. Upon request by the designated representative, the Administrator may specify reasonable extensions of such time period. Within the time period (including any such extensions) specified by the Administrator, the designated representative shall resubmit the quarterly report with the corrections specified by the Administrator, except to the extent the designated representative provides information demonstrating that a specified correction is not necessary because the quarterly report already meets the requirements of this subpart and part 75 of this chapter that are relevant to the specified correction.

(ii) Any resubmission of a quarterly report shall meet the requirements applicable to the submission of a quarterly report under this subpart and part 75 of this chapter, except for the deadline set forth in paragraph (d)(2) of this section.

(e) Compliance certification. The designated representative shall submit to the Administrator a compliance certification (in a format prescribed by the Administrator) in support of each quarterly report based on reasonable inquiry of those persons with primary responsibility for ensuring that all of the unit's emissions are correctly and fully monitored. The certification shall state that:

(1) The monitoring data submitted were recorded in accordance with the applicable requirements of this subpart and part 75 of this chapter, including the quality assurance procedures and specifications; and

(2) For a unit with add-on SO2 emission controls and for all hours where SO2 data are substituted in accordance with § 75.34(a)(1) of this chapter, the add-on emission controls were operating within the range of parameters listed in the quality assurance/quality control program under appendix B to part 75 of this chapter and the substitute data values do not systematically underestimate SO2 emissions.

(a) The designated representative of a Texas SO2 Trading Program unit may submit a petition under § 75.66 of this chapter to the Administrator, requesting approval to apply an alternative to any requirement of §§ 97.930 through 97.934.

(b) A petition submitted under paragraph (a) of this section shall include sufficient information for the evaluation of the petition, including, at a minimum, the following information:
