      (i) If total SO2 emissions during a control period in a given year from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources exceed the State assurance level, then the owners and operators of such sources and units in each group of one or more sources and units having a common designated representative for such control period, where the common designated representative's share of such SO2 emissions during such control period exceeds the common designated representative's assurance level for such control period, shall hold (in the assurance account established for the owners and operators of such group) Texas SO2 Trading Program allowances available for deduction for such control period under § 97.925(a) in an amount equal to two times the product (rounded to the nearest whole number), as determined by the Administrator in accordance with § 97.925(b), of multiplying -- 
         (A) The quotient of the amount by which the common designated representative's share of such SO2 emissions exceeds the common designated representative's assurance level divided by the sum of the amounts, determined for all common designated representatives for such sources and units for such control period, by which each common designated representative's share of such SO2 emissions exceeds the respective common designated representative's assurance level; and
         (B) The amount by which total SO2 emissions from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources for such control period exceed the State assurance level.
      (ii) The owners and operators shall hold the Texas SO2 Trading Program allowances required under paragraph (c)(2)(i) of this section, as of midnight of November 1 (if it is a business day), or midnight of the first business day thereafter (if November 1 is not a business day), immediately after the year of such control period.
      (iii) Total SO2 emissions from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources during a control period in a given year exceed the State assurance level if such total SO2 emissions exceed the sum, for such control period, of the Texas SO2 Trading Program budget under § 97.910(a)(1) and the variability limit under § 97.910(b).
      (iv) It shall not be a violation of this subpart or of the Clean Air Act if total SO2 emissions from all Texas SO2 Trading Program units at Texas SO2 Trading Program sources during a control period exceed the State assurance level or if a common designated representative's share of total SO2 emissions from the Texas SO2 Trading Program units at Texas SO2 Trading Program sources during a control period exceeds the common designated representative's assurance level.
      (v) To the extent the owners and operators fail to hold Texas SO2 Trading Program allowances for a control period in a given year in accordance with paragraphs (c)(2)(i) through (iii) of this section,
         (A) The owners and operators shall pay any fine, penalty, or assessment or comply with any other remedy imposed under the Clean Air Act; and
         (B) Each Texas SO2 Trading Program allowance that the owners and operators fail to hold for such control period in accordance with paragraphs (c)(2)(i) through (iii) of this section and each day of such control period shall constitute a separate violation of this subpart and the Clean Air Act.
   (3) Compliance periods.

   (4) Vintage of Texas SO2 Trading Program allowances held for compliance. 
      (i) A Texas SO2 Trading Program allowance held for compliance with the requirements under paragraph (c)(1)(i) of this section for a control period in a given year must be a Texas SO2 Trading Program allowance that was allocated for such control period or a control period in a prior year.
      (ii) A Texas SO2 Trading Program allowance held for compliance with the requirements under paragraphs (c)(1)(ii)(A) and (c)(2)(i) through (iii) of this section for a control period in a given year must be a Texas SO2 Trading Program allowance that was allocated for a control period in a prior year or the control period in the given year or in the immediately following year.
   (5) Allowance Management System requirements. 
      Each Texas SO2 Trading Program allowance shall be held in, deducted from, or transferred into, out of, or between Allowance Management System accounts in accordance with this subpart.
   (6) Limited authorization. 
      A Texas SO2 Trading Program allowance is a limited authorization to emit one ton of SO2 during the control period in one year. Such authorization is limited in its use and duration as follows:
         (i) Such authorization shall only be used in accordance with the Texas SO2 Trading Program; and
         (ii) Notwithstanding any other provision of this subpart, the Administrator has the authority to terminate or limit the use and duration of such authorization to the extent the Administrator determines is necessary or appropriate to implement any provision of the Clean Air Act.

(d) Title V permit requirements. 
   (1) No title V permit revision shall be required for any allocation, holding, deduction, or transfer of Texas SO2 Trading Program allowances in accordance with this subpart.
   (2) A description of whether a unit is required to monitor and report SO2 emissions using a continuous emission monitoring system (under subpart B of part 75 of this chapter), an excepted monitoring system (under appendices D and E to part 75 of this chapter), a low mass emissions excepted monitoring methodology (under § 75.19 of this chapter), or an alternative monitoring system (under subpart E of part 75 of this chapter) in accordance with §§ 97.930 through 97.935 may be added to, or changed in, a title V permit using minor permit modification procedures in accordance with §§ 70.7(e)(2) and 71.7(e)(1) of this chapter, provided that the requirements applicable to the described monitoring and reporting (as added or changed, respectively) are already incorporated in such permit. This paragraph explicitly provides that the addition of, or change to, a unit's description as described in the prior sentence is eligible for minor permit modification procedures in accordance with §§ 70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.
(e) Additional recordkeeping and reporting requirements. 
   (1) Unless otherwise provided, the owners and operators of each Texas SO2 Trading Program source and each Texas SO2 Trading Program unit at the source shall keep on site at the source each of the following documents (in hardcopy or electronic format) for a period of 5 years from the date the document is created. This period may be extended for cause, at any time before the end of 5 years, in writing by the Administrator.
      (i) The certificate of representation under § 97.916 for the designated representative for the source and each Texas SO2 Trading Program unit at the source and all documents that demonstrate the truth of the statements in the certificate of representation; provided that the certificate and documents shall be retained on site at the source beyond such 5-year period until such certificate of representation and documents are superseded because of the submission of a new certificate of representation under § 97.916 changing the designated representative.
      (ii) All emissions monitoring information, in accordance with this subpart.
      (iii) Copies of all reports, compliance certifications, and other submissions and all records made or required under, or to demonstrate compliance with the requirements of, the Texas SO2 Trading Program.
   (2) The designated representative of a Texas SO2 Trading Program source and each Texas SO2 Trading Program unit at the source shall make all submissions required under the Texas SO2 Trading Program, except as provided in § 97.918. This requirement does not change, create an exemption from, or otherwise affect the responsible official submission requirements under a title V operating permit program in parts 70 and 71 of this chapter.
(f) Liability. 
   (1) Any provision of the Texas SO2 Trading Program that applies to a Texas SO2 Trading Program source or the designated representative of a Texas SO2 Trading Program source shall also apply to the owners and operators of such source and of the Texas SO2 Trading Program units at the source.
   (2) Any provision of the Texas SO2 Trading Program that applies to a Texas SO2 Trading Program unit or the designated representative of a Texas SO2 Trading Program unit shall also apply to the owners and operators of such unit.
(g) Effect on other authorities.

      (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.
§ 97.912   Texas SO2 Trading Program Supplemental Allowance Pool.
   (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 February 15 of 2022 and 2023 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).
§ 97.913   Authorization of designated representative and alternate designated representative.
   (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.

      (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.
§ 97.914   Responsibilities of designated representative and 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.
§ 97.915   Changing designated representative and alternate designated representative; changes in owners and operators; changes in units at the source.
   (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. Notwithstanding any such change, all representations, actions, inactions, and submissions by the previous alternate designated representative before the time and date when the Administrator receives the superseding certificate of representation shall be binding on the new alternate designated representative, the designated representative, and the owners and operators of the Texas SO2 Trading Program source and the Texas SO2 Trading Program units at the source.
   (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.
   (d) Changes in units at the source. 
      Within 30 days of any change in which units are located at a Texas SO2 Trading Program source (including the addition or removal of a unit), the designated representative or any alternate designated representative shall submit a certificate of representation under § 97.916 amending the list of units to reflect the change.
         (1) If the change is the addition of a unit that operated (other than for purposes of testing by the manufacturer before initial installation) before being located at the source, then the certificate of representation shall identify, in a format prescribed by the Administrator, the entity from whom the unit was purchased or otherwise obtained (including name, address, telephone number, and facsimile number (if any)), the date on which the unit was purchased or otherwise obtained, and the date on which the unit became located at the source.
         (2) If the change is the removal of a unit, then the certificate of representation shall identify, in a format prescribed by the Administrator, the entity to which the unit was sold or that otherwise obtained the unit (including name, address, telephone number, and facsimile number (if any)), the date on which the unit was sold or otherwise obtained, and the date on which the unit became no longer located at the source.
§ 97.916   Certificate of representation.
   (a) A complete certificate of representation for a designated representative or an alternate designated representative shall include the following elements in a format prescribed by the Administrator:
      (1) Identification of the Texas SO2 Trading Program source, and each Texas SO2 Trading Program unit at the source, for which the certificate of representation is submitted, including source name, source category and NAICS code (or, in the absence of a NAICS code, an equivalent code), State, plant code, county, latitude and longitude, unit identification number and type, identification number and nameplate capacity (in MWe, rounded to the nearest tenth) of each generator served by each such unit, and actual date of commencement of commercial operation, and a statement of whether such source is located in Indian country.
      (2) The name, address, email address (if any), telephone number, and facsimile transmission number (if any) of the designated representative and any alternate designated representative.

         (ii) "I certify that I have all the necessary authority to carry out my duties and responsibilities under the Texas SO2 Trading Program on behalf of the owners and operators of the source and of each Texas SO2 Trading Program unit at the source and that each such owner and operator shall be fully bound by my representations, actions, inactions, or submissions and by any decision or order issued to me by the Administrator regarding the source or unit."
         (iii) "Where there are multiple holders of a legal or equitable title to, or a leasehold interest in, a Texas SO2 Trading Program unit, or where a utility or industrial customer purchases power from a Texas SO2 Trading Program unit under a life-of-the-unit, firm power contractual arrangement, I certify that: I have given a written notice of my selection as the `designated representative' or `alternate designated representative', as applicable, and of the agreement by which I was selected to each owner and operator of the source and of each Texas SO2 Trading Program unit at the source; and Texas SO2 Trading Program allowances and proceeds of transactions involving Texas SO2 Trading Program allowances will be deemed to be held or distributed in proportion to each holder's legal, equitable, leasehold, or contractual reservation or entitlement, except that, if such multiple holders have expressly provided for a different distribution of Texas SO2 Trading Program allowances by contract, Texas SO2 Trading Program allowances and proceeds of transactions involving Texas SO2 Trading Program allowances will be deemed to be held or distributed in accordance with the contract."
      (5) The signature of the designated representative and any alternate designated representative and the dates signed.
   (b) Unless otherwise required by the Administrator, documents of agreement referred to in the certificate of representation shall not be submitted to the Administrator. The Administrator shall not be under any obligation to review or evaluate the sufficiency of such documents, if submitted.
§ 97.917   Objections concerning designated representative and alternate designated representative.
   (a) Once a complete certificate of representation under § 97.916 has been submitted and received, the Administrator will rely on the certificate of representation unless and until a superseding complete certificate of representation under § 97.916 is received by the Administrator.
   (b) Except as provided in paragraph (a) of this section, no objection or other communication submitted to the Administrator concerning the authorization, or any representation, action, inaction, or submission, of a designated representative or alternate designated representative shall affect any representation, action, inaction, or submission of the designated representative or alternate designated representative or the finality of any decision or order by the Administrator under the Texas SO2 Trading Program.
   (c) The Administrator will not adjudicate any private legal dispute concerning the authorization or any representation, action, inaction, or submission of any designated representative or alternate designated representative, including private legal disputes concerning the proceeds of Texas SO2 Trading Program allowance transfers.

         (ii) "Until this notice of delegation is superseded by another notice of delegation under 40 CFR 97.918(d), I agree to maintain an email account and to notify the Administrator immediately of any change in my email address unless all delegation of authority by me under 40 CFR 97.918 is terminated."
   (d) A notice of delegation submitted under paragraph (c) of this section shall be effective, with regard to the designated representative or alternate designated representative identified in such notice, upon receipt of such notice by the Administrator and until receipt by the Administrator of a superseding notice of delegation submitted by such designated representative or alternate designated representative, as appropriate. The superseding notice of delegation may replace any previously identified agent, add a new agent, or eliminate entirely any delegation of authority.
   (e) Any electronic submission covered by the certification in paragraph (c)(4)(i) of this section and made in accordance with a notice of delegation effective under paragraph (d) of this section shall be deemed to be an electronic submission by the designated representative or alternate designated representative submitting such notice of delegation.
§ 97.919   [Reserved]
§ 97.920   Establishment of compliance accounts, assurance accounts, and general accounts.

            (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)(iii)(B) 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)(iii)(B) 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)(iii)(B) 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)(iii)(B) 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)(iii)(B) 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.
§ 97.926   Banking.
   (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.
§ 97.927   Account error.
   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.
§ 97.928   Administrator's action on submissions.
   (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.
