Measurements, abbreviations, and acronyms used in this part are defined as follows:

(a) The following units in a State shall be NOX Budget units, and any source that includes one or more such units shall be a NOX Budget source, subject to the requirements of this part:

(1) Any unit that, any time on or after January 1, 1995, serves a generator with a nameplate capacity greater than 25 MWe and sells any amount of electricity; or

(2) Any unit that is not a unit under paragraph (a) of this section and that has a maximum design heat input greater than 250 mmBtu/hr.

(b) Notwithstanding paragraph (a) of this section, a unit under paragraph (a) of this section shall be subject only to the requirements of this paragraph (b) if the unit has a federally enforceable permit that meets the requirements of paragraph (b)(1) of this section and restricts the unit to burning only natural gas or fuel oil during a control period in 2003 or later and each control period thereafter and restricts the unit's operating hours during each such control period to the number of hours (determined in accordance with paragraph (b)(1)(ii) and (iii) of this section) that limits the unit's potential NOX mass emissions for the control period to 25 tons or less. Notwithstanding paragraph (a) of this section, starting with the effective date of such federally enforceable permit, the unit shall not be a NOX Budget unit.

(1) For each control period under paragraph (b) of this section, the federally enforceable permit must:

(i) Restrict the unit to burning only natural gas or fuel oil.

(ii) Restrict the unit's operating hours to the number calculated by dividing 25 tons of potential NOX mass emissions by the unit's maximum potential hourly NOX mass emissions.

(iii) Require that the unit's potential NOX mass emissions shall be calculated as follows:

(A) Select the default NOX emission rate in Table 2 of § 75.19 of this chapter that would otherwise be applicable assuming that the unit burns only the type of fuel (i.e., only natural gas or only fuel oil) that has the highest default NOX emission factor of any type of fuel that the unit is allowed to burn under the fuel use restriction in paragraph (b)(1)(i) of this section; and

(B) Multiply the default NOX emission rate under paragraph (b)(1)(iii)(A) of this section by the unit's maximum rated hourly heat input. The owner or operator of the unit may petition the permitting authority to use a lower value for the unit's maximum rated hourly heat input than the value as defined under § 96.2. The permitting authority may approve such lower value if the owner or operator demonstrates that the maximum hourly heat input specified by the manufacturer or the highest observed hourly heat input, or both, are not representative, and that such lower value is representative, of the unit's current capabilities because modifications have been made to the unit, limiting its capacity permanently.

(iv) Require that the owner or operator of the unit shall retain at the source that includes the unit, for 5 years, records demonstrating that the operating hours restriction, the fuel use restriction, and the other requirements of the permit related to these restrictions were met.

(v) Require that the owner or operator of the unit shall report the unit's hours of operation (treating any partial hour of operation as a whole hour of operation) during each control period to the permitting authority by November 1 of each year for which the unit is subject to the federally enforceable permit.

(2) The permitting authority that issues the federally enforceable permit with the fuel use restriction under paragraph (b)(1)(i) and the operating hours restriction under paragraphs (b)(1)(ii) and (iii) of this section will notify the Administrator in writing of each unit under paragraph (a) of this section whose federally enforceable permit issued by the permitting authority includes such restrictions. The permitting authority will also notify the Administrator in writing of each unit under paragraph (a) of this section whose federally enforceable permit issued by the permitting authority is revised to remove any such restriction, whose federally enforceable permit issued by the permitting authority includes any such restriction that is no longer applicable, or which does not comply with any such restriction.

(3) If, for any control period under paragraph (b) of this section, the fuel use restriction under paragraph (b)(1)(i) of this section or the operating hours restriction under paragraphs (b)(1)(ii) and (iii) of this section is removed from the unit's federally enforceable permit or otherwise becomes no longer applicable or if, for any such control period, the unit does not comply with the fuel use restriction under paragraph (b)(1)(i) of this section or the operating hours restriction under paragraphs (b)(1)(ii) and (iii) of this section, the unit shall be a NOX Budget unit, subject to the requirements of this part. Such unit shall be treated as commencing operation and, for a unit under paragraph (a)(1) of this section, commencing commercial operation on September 30 of the control period for which the fuel use restriction or the operating hours restriction is no longer applicable or during which the unit does not comply with the fuel use restriction or the operating hours restriction.

(a) This section applies to any NOX Budget unit, other than a NOX Budget opt-in source, that is permanently retired.

(b)(1) Any NOX Budget unit, other than a NOX Budget opt-in source, that is permanently retired shall be exempt from the NOX Budget Trading Program, except for the provisions of this section, §§ 96.2, 96.3, 96.4, 96.7 and subparts E, F, and G of this part.

(a) Interim review of monitoring plan. The permitting authority will determine, on an interim basis, the sufficiency of the monitoring plan accompanying the initial application for a NOX Budget opt-in permit under § 96.83. A monitoring plan is sufficient, for purposes of interim review, if the plan appears to contain information demonstrating that the NOX emissions rate and heat input of the unit are monitored and reported in accordance with subpart H of this part. A determination of sufficiency shall not be construed as acceptance or approval of the unit's monitoring plan.

(b) If the permitting authority determines that the unit's monitoring plan is sufficient under paragraph (a) of this section and after completion of monitoring system certification under subpart H of this part, the NOX emissions rate and the heat input of the unit shall be monitored and reported in accordance with subpart H of this part for one full control period during which monitoring system availability is not less than 90 percent and during which the unit is in full compliance with any applicable State or Federal emissions or emissions-related requirements. Solely for purposes of applying the requirements in the prior sentence, the unit shall be treated as a “NOX Budget unit” prior to issuance of a NOX Budget opt-in permit covering the unit.

(c) Based on the information monitored and reported under paragraph (b) of this section, the unit's baseline heat rate shall be calculated as the unit's total heat input (in mmBtu) for the control period and the unit's baseline NOX emissions rate shall be calculated as the unit's total NOX emissions (in lb) for the control period divided by the unit's baseline heat rate.

(d) After calculating the baseline heat input and the baseline NOX emissions rate for the unit under paragraph (c) of this section, the permitting authority will serve a draft NOX Budget opt-in permit on the NOX authorized account representative of the unit.

(e) Confirmation of intention to opt-in. Within 20 days after the issuance of the draft NOX Budget opt-in permit, the NOX authorized account representative of the unit must submit to the permitting authority a confirmation of the intention to opt in the unit or a withdrawal of the application for a NOX Budget opt-in permit under § 96.83. The permitting authority will treat the failure to make a timely submission as a withdrawal of the NOX Budget opt-in permit application.

(f) Issuance of draft NO X Budget opt-in permit. If the NOX authorized account representative confirms the intention to opt-in the unit under paragraph (e) of this section, the permitting authority will issue the draft NOX Budget opt-in permit in accordance with § 96.20.

(g) Notwithstanding paragraphs (a) through (f) of this section, if at any time before issuance of a draft NOX Budget opt-in permit for the unit, the permitting authority determines that the unit does not qualify as a NOX Budget opt-in source under § 96.80, the permitting authority will issue a draft denial of a NOX Budget opt-in permit for the unit in accordance with § 96.20.

(h) Withdrawal of application for NO X Budget opt-in permit. A NOX authorized account representative of a unit may withdraw its application for a NOX Budget opt-in permit under § 96.83 at any time prior to the issuance of the final NOX Budget opt-in permit. Once the application for a NOX Budget opt-in permit is withdrawn, a NOX authorized account representative wanting to reapply must submit a new application for a NOX Budget permit under § 96.83.

(i) Effective date. The effective date of the initial NOX Budget opt-in permit shall be May 1 of the first control period starting after the issuance of the initial NOX Budget opt-in permit by the permitting authority. The unit shall be a NOX Budget opt-in source and a NOX Budget unit as of the effective date of the initial NOX Budget opt-in permit.

(a) Each NOX Budget opt-in permit (including any draft or proposed NOX Budget opt-in permit, if applicable) will contain all elements required for a complete NOX Budget opt-in permit application under § 96.22 as approved or adjusted by the permitting authority.

(b) Each NOX Budget opt-in permit is deemed to incorporate automatically the definitions of terms under § 96.2 and, upon recordation by the Administrator under subpart F, G, or I of this part, every allocation, transfer, or deduction of NOX allowances to or from the compliance accounts of each NOX Budget opt-in source covered by the NOX Budget opt-in permit or the overdraft account of the NOX Budget source where the NOX Budget opt-in source is located.

(a) Requesting withdrawal. To withdraw from the NOX Budget Trading Program, the NOX authorized account representative of a NOX Budget opt-in source shall submit to the permitting authority a request to withdraw effective as of a specified date prior to May 1 or after September 30. The submission shall be made no later than 90 days prior to the requested effective date of withdrawal.

The State trading budgets for annual allocations of CAIR NOX allowances for the control periods in 2009 through 2014 and in 2015 and thereafter are respectively as follows:

(a) By October 31, 2006, the permitting authority will submit to the Administrator the CAIR NOX allowance allocations, in a format prescribed by the Administrator and in accordance with § 96.142(a) and (b), for the control periods in 2009, 2010, 2011, 2012, 2013, and 2014.

(b) By October 31, 2009 and October 31 of each year thereafter, the permitting authority will submit to the Administrator the CAIR NOX allowance allocations, in a format prescribed by the Administrator and in accordance with § 96.142(a) and (b), for the control period in the sixth year after the year of the applicable deadline for submission under this paragraph.

(c) By October 31, 2009 and October 31 of each year thereafter, the permitting authority will submit to the Administrator the CAIR NOX allowance allocations, in a format prescribed by the Administrator and in accordance with § 96.142(a), (c), and (d), for the control period in the year of the applicable deadline for submission under this paragraph.

(a)(1) The baseline heat input (in mmBtu) used with respect to CAIR NOX allowance allocations under paragraph (b) of this section for each CAIR NOX unit will be:

(i) For units commencing operation before January 1, 2001 the average of the 3 highest amounts of the unit's adjusted control period heat input for 2000 through 2004, with the adjusted control period heat input for each year calculated as follows:

(A) If the unit is coal-fired during the year, the unit's control period heat input for such year is multiplied by 100 percent;

(B) If the unit is oil-fired during the year, the unit's control period heat input for such year is multiplied by 60 percent; and

(C) If the unit is not subject to paragraph (a)(1)(i)(A) or (B) of this section, the unit's control period heat input for such year is multiplied by 40 percent.

(ii) For units commencing operation on or after January 1, 2001 and operating each calendar year during a period of 5 or more consecutive calendar years, the average of the 3 highest amounts of the unit's total converted control period heat input over the first such 5 years.

(2)(i) A unit's control period heat input, and a unit's status as coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) of this section, and a unit's total tons of NOX emissions during a calendar year under paragraph (c)(3) of this section, will be determined in accordance with part 75 of this chapter, to the extent the unit was otherwise subject to the requirements of part 75 of this chapter for the year, or will be based on the best available data reported to the permitting authority for the unit, to the extent the unit was not otherwise subject to the requirements of part 75 of this chapter for the year.

(ii) A unit's converted control period heat input for a calendar year specified under paragraph (a)(1)(ii) of this section equals:

(A) Except as provided in paragraph (a)(2)(ii)(B) or (C) of this section, the control period gross electrical output of the generator or generators served by the unit multiplied by 7,900 Btu/kWh, if the unit is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal-fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that if a generator is served by 2 or more units, then the gross electrical output of the generator will be attributed to each unit in proportion to the unit's share of the total control period heat input of such units for the year;

(B) For a unit that is a boiler and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the total heat energy (in Btu) of the steam produced by the boiler during the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or

(C) For a unit that is a combustion turbine and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the control period gross electrical output of the enclosed device comprising the compressor, combustor, and turbine multiplied by 3,413 Btu/kWh, plus the total heat energy (in Btu) of the steam produced by any associated heat recovery steam generator during the control period divided by 0.8, and with the sum divided by 1,000,000 Btu/mmBtu.

(b)(1) For each control period in 2009 and thereafter, the permitting authority will allocate to all CAIR NOX units in the State that have a baseline heat input (as determined under paragraph (a) of this section) a total amount of CAIR NOX allowances equal to 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the tons of NOX emissions in the State trading budget under § 96.140 (except as provided in paragraph (d) of this section).

(2) The permitting authority will allocate CAIR NOX allowances to each CAIR NOX unit under paragraph (b)(1) of this section in an amount determined by multiplying the total amount of CAIR NOX allowances allocated under paragraph (b)(1) of this section by the ratio of the baseline heat input of such CAIR NOX unit to the total amount of baseline heat input of all such CAIR NOX units in the State and rounding to the nearest whole allowance as appropriate.

(c) For each control period in 2009 and thereafter, the permitting authority will allocate CAIR NOX allowances to CAIR NOX units in a State that are not allocated CAIR NOX allowances under paragraph (b) of this section because the units do not yet have a baseline heat input under paragraph (a) of this section or because the units have a baseline heat input but all CAIR NOX allowances available under paragraph (b) of this section for the control period are already allocated, in accordance with the following procedures:

(1) The permitting authority will establish a separate new unit set-aside for each control period. Each new unit set-aside will be allocated CAIR NOX allowances equal to 5 percent for a control period in 2009 through 2014, and 3 percent for a control period in 2015and thereafter, of the amount of tons of NOX emissions in the State trading budget under § 96.140.

(2) The CAIR designated representative of such a CAIR NOX unit may submit to the permitting authority a request, in a format specified by the permitting authority, to be allocated CAIR NOX allowances, starting with the later of the control period in 2009 or the first control period after the control period in which the CAIR NOX unit commences commercial operation and until the first control period for which the unit is allocated CAIR NOX allowances under paragraph (b) of this section. A separate CAIR NOX allowance allocation request for each control period for which CAIR NOX allowances are sought must be submitted on or before May 1 of such control period and after the date on which the CAIR NOX unit commences commercial operation.

(3) In a CAIR NOX allowance allocation request under paragraph (c)(2) of this section, the CAIR designated representative may request for a control period CAIR NOX allowances in an amount not exceeding the CAIR NOX unit's total tons of NOX emissions during the calendar year immediately before such control period.

(4) The permitting authority will review each CAIR NOX allowance allocation request under paragraph (c)(2) of this section and will allocate CAIR NOX allowances for each control period pursuant to such request as follows:

(i) The permitting authority will accept an allowance allocation request only if the request meets, or is adjusted by the permitting authority as necessary to meet, the requirements of paragraphs (c)(2) and (3) of this section.

(ii) On or after May 1 of the control period, the permitting authority will determine the sum of the CAIR NOX allowances requested (as adjusted under paragraph (c)(4)(i) of this section) in all allowance allocation requests accepted under paragraph (c)(4)(i) of this section for the control period.

(iii) If the amount of CAIR NOX allowances in the new unit set-aside for the control period is greater than or equal to the sum under paragraph (c)(4)(ii) of this section, then the permitting authority will allocate the amount of CAIR NOX allowances requested (as adjusted under paragraph (c)(4)(i) of this section) to each CAIR NOX unit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section.

(iv) If the amount of CAIR NOX allowances in the new unit set-aside for the control period is less than the sum under paragraph (c)(4)(ii) of this section, then the permitting authority will allocate to each CAIR NOX unit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section the amount of the CAIR NOX allowances requested (as adjusted under paragraph (c)(4)(i) of this section), multiplied by the amount of CAIR NOX allowances in the new unit set-aside for the control period, divided by the sum determined under paragraph (c)(4)(ii) of this section, and rounded to the nearest whole allowance as appropriate.

(v) The permitting authority will notify each CAIR designated representative that submitted an allowance allocation request of the amount of CAIR NOX allowances (if any) allocated for the control period to the CAIR NOX unit covered by the request.

(d) If, after completion of the procedures under paragraph (c)(4) of this section for a control period, any unallocated CAIR NOX allowances remain in the new unit set-aside for the control period, the permitting authority will allocate to each CAIR NOX unit that was allocated CAIR NOX allowances under paragraph (b) of this section an amount of CAIR NOX allowances equal to the total amount of such remaining unallocated CAIR NOX allowances, multiplied by the unit's allocation under paragraph (b) of this section, divided by 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the amount of tons of NOX emissions in the State trading budget under § 96.140, and rounded to the nearest whole allowance as appropriate.

(a) In addition to the CAIR NOX allowances allocated under § 96.142, the permitting authority may allocate for the control period in 2009 up to the following amount of CAIR NOX allowances to CAIR NOX units in the respective State:

(b) For any CAIR NOX unit in the State that achieves NOX emission reductions in 2007 and 2008 that are not necessary to comply with any State or federal emissions limitation applicable during such years, the CAIR designated representative of the unit may request early reduction credits, and allocation of CAIR NOX allowances from the compliance supplement pool under paragraph (a) of this section for such early reduction credits, in accordance with the following:

(1) The owners and operators of such CAIR NOX unit shall monitor and report the NOX emissions rate and the heat input of the unit in accordance with subpart HH of this part in each control period for which early reduction credit is requested.

(2) The CAIR designated representative of such CAIR NOX unit shall submit to the permitting authority by May 1, 2009 a request, in a format specified by the permitting authority, for allocation of an amount of CAIR NOX allowances from the compliance supplement pool not exceeding the sum of the amounts (in tons) of the unit's NOX emission reductions in 2007 and 2008 that are not necessary to comply with any State or federal emissions limitation applicable during such years, determined in accordance with subpart HH of this part.

(c) For any CAIR NOX unit in the State whose compliance with the CAIR NOX emissions limitation for the control period in 2009 would create an undue risk to the reliability of electricity supply during such control period, the CAIR designated representative of the unit may request the allocation of CAIR NOX allowances from the compliance supplement pool under paragraph (a) of this section, in accordance with the following:

(1) The CAIR designated representative of such CAIR NOX unit shall submit to the permitting authority by May 1, 2009 a request, in a format specified by the permitting authority, for allocation of an amount of CAIR NOX allowances from the compliance supplement pool not exceeding the minimum amount of CAIR NOX allowances necessary to remove such undue risk to the reliability of electricity supply.

(2) In the request under paragraph (c)(1) of this section, the CAIR designated representative of such CAIR NOX unit shall demonstrate that, in the absence of allocation to the unit of the amount of CAIR NOX allowances requested, the unit's compliance with the CAIR NOX emissions limitation for the control period in 2009 would create an undue risk to the reliability of electricity supply during such control period. This demonstration must include a showing that it would not be feasible for the owners and operators of the unit to:

(i) Obtain a sufficient amount of electricity from other electricity generation facilities, during the installation of control technology at the unit for compliance with the CAIR NOX emissions limitation, to prevent such undue risk; or

(ii) Obtain under paragraphs (b) and (d) of this section, or otherwise obtain, a sufficient amount of CAIR NOX allowances to prevent such undue risk.

(d) The permitting authority will review each request under paragraph (b) or (c) of this section submitted by May 1, 2009 and will allocate CAIR NOX allowances for the control period in 2009 to CAIR NOX units in the State and covered by such request as follows:

(1) Upon receipt of each such request, the permitting authority will make any necessary adjustments to the request to ensure that the amount of the CAIR NOX allowances requested meets the requirements of paragraph (b) or (c) of this section.

(2) If the State's compliance supplement pool under paragraph (a) of this section has an amount of CAIR NOX allowances not less than the total amount of CAIR NOX allowances in all such requests (as adjusted under paragraph (d)(1) of this section), the permitting authority will allocate to each CAIR NOX unit covered by such requests the amount of CAIR NOX allowances requested (as adjusted under paragraph (d)(1) of this section).

(3) If the State's compliance supplement pool under paragraph (a) of this section has a smaller amount of CAIR NOX allowances than the total amount of CAIR NOX allowances in all such requests (as adjusted under paragraph (d)(1) of this section), the permitting authority will allocate CAIR NOX allowances to each CAIR NOX unit covered by such requests according to the following formula and rounding to the nearest whole allowance as appropriate:

(4) By November 30, 2009, the permitting authority will determine, and submit to the Administrator, the allocations under paragraph (d)(2) or (3)of this section.

(5) By January 1, 2010, the Administrator will record the allocations under paragraph (d)(4) of this section.

(d) By December 1, 2009 and December 1 of each year thereafter, the Administrator will record in the CAIR NOX source's compliance account the CAIR NOX allowances allocated for the CAIR NOX units at the source, as submitted by the permitting authority or determined by the Administrator in accordance with § 96.141(c), for the control period in the year of the applicable deadline for recordation under this paragraph.

(e) Serial numbers for allocated CAIR NO X allowances. When recording the allocation of CAIR NO X allowances for a CAIR NOX unit in a compliance account, the Administrator will assign each CAIR NOX allowance a unique identification number that will include digits identifying the year of the control period for which the CAIR NOX allowance is allocated.

(a) Allowance transfer deadline. The CAIR NOX allowances are available to be deducted for compliance with a source's CAIR NOX emissions limitation for a control period in a given calendar year only if the CAIR NOX allowances:

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

(2) Are held in the compliance account as of the allowance transfer deadline for the control period or are transferred into the compliance account by a CAIR NOX allowance transfer correctly submitted for recordation under §§ 96.160 and 96.161 by the allowance transfer deadline for the control period.

(b) Deductions for compliance. Following the recordation, in accordance with § 96.161, of CAIR NOX allowance transfers submitted for recordation in a source's compliance account by the allowance transfer deadline for a control period, the Administrator will deduct from the compliance account CAIR NOX allowances available under paragraph (a) of this section in order to determine whether the source meets the CAIR NOX emissions limitation for the control period, as follows:

(1) Until the amount of CAIR NOX allowances deducted equals the number of tons of total nitrogen oxides emissions, determined in accordance with subpart HH of this part, from all CAIR NOX units at the source for the control period; or

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

(c)(1) Identification of CAIR NO X allowances by serial number. The CAIR authorized account representative for a source's compliance account may request that specific CAIR NO X allowances, identified by serial number, in the compliance account be deducted for emissions or excess emissions for a control period in accordance with paragraph (b) or (d) of this section. Such request shall be submitted to the Administrator by the allowance transfer deadline for the control period and include, in a format prescribed by the Administrator, the identification of the CAIR NOX source and the appropriate serial numbers.

(2) First-in, first-out. The Administrator will deduct CAIR NOX allowances under paragraph (b) or (d) of this section from the source's compliance account, in the absence of an identification or in the case of a partial identification of CAIR NOX allowances by serial number under paragraph (c)(1) of this section, on a first-in, first-out (FIFO) accounting basis in the following order:

(i) Any CAIR NOX allowances that were allocated to the units at the source, in the order of recordation; and then

(ii) Any CAIR NOX allowances that were allocated to any entity and transferred and recorded in the compliance account pursuant to subpart GG of this part, in the order of recordation.

(d) Deductions for excess emissions. (1) After making the deductions for compliance under paragraph (b) of this section for a control period in a calendar year in which the CAIR NOX source has excess emissions, the Administrator will deduct from the source's compliance account an amount of CAIR NOX allowances, allocated for the control period in the immediately following calendar year, equal to 3 times the number of tons of the source's excess emissions.

(2) Any allowance deduction required under paragraph (d)(1) of this section shall not affect the liability of the owners and operators of the CAIR NOX source or the CAIR NOX units at the source for any fine, penalty, or assessment, or their obligation to comply with any other remedy, for the same violations, as ordered under the Clean Air Act or applicable State law.

(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 and subpart II.

(f) Administrator's action on submissions. (1) The Administrator may review and conduct independent audits concerning any submission under the CAIR NOX Annual Trading Program and make appropriate adjustments of the information in the submissions.

(2) The Administrator may deduct CAIR NOX allowances from or transfer CAIR NOX allowances to a source's compliance account based on the information in the submissions, as adjusted under paragraph (f)(1) of this section, and record such deductions and transfers.

(a) CAIR NOX allowances may be banked for future use or transfer in a compliance account or a general account in accordance with paragraph (b) of this section.

(b) Any CAIR NOX allowance that is held in a compliance account or a general account will remain in such account unless and until the CAIR NOX allowance is deducted or transferred under § 96.154, § 96.156, or subpart GG or II of this part.

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

(a) The CAIR authorized account representative of a general account may submit to the Administrator a request to close the account, which shall include a correctly submitted allowance transfer under §§ 96.160 and 96.161 for any CAIR NOX allowances in the account to one or more other CAIR NOX Allowance Tracking System accounts.

(b) If a general account has no allowance transfers in or out of the account for a 12-month period or longer and does not contain any CAIR NOX allowances, the Administrator may notify the CAIR authorized account representative for the account that the account will be closed following 20 business days after the notice is sent. The account will be closed after the 20-day period unless, before the end of the 20-day period, the Administrator receives a correctly submitted transfer of CAIR NOX allowances into the account under §§ 96.160 and 96.161 or a statement submitted by the CAIR authorized account representative demonstrating to the satisfaction of the Administrator good cause as to why the account should not be closed.

A CAIR authorized account representative seeking recordation of a CAIR NOX allowance transfer shall submit the transfer to the Administrator. To be considered correctly submitted, the CAIR NOX allowance transfer shall include the following elements, in a format specified by the Administrator:

(a) The account numbers for both the transferor and transferee accounts;

(b) The serial number of each CAIR NOX allowance that is in the transferor account and is to be transferred; and

(c) The name and signature of the CAIR authorized account representative of the transferor account and the date signed.

(a) Within 5 business days (except as provided in paragraph (b) of this section) of receiving a CAIR NOX allowance transfer, the Administrator will record a CAIR NOX allowance transfer by moving each CAIR NOX allowance from the transferor account to the transferee account as specified by the request, provided that:

(1) The transfer is correctly submitted under § 96.160; and

(2) The transferor account includes each CAIR NOX allowance identified by serial number in the transfer.

(b) A CAIR NOX allowance transfer that is submitted for recordation after the allowance transfer deadline for a control period and that includes any CAIR NOX allowances allocated for any control period before such allowance transfer deadline will not be recorded until after the Administrator completes the deductions under § 96.154 for the control period immediately before such allowance transfer deadline.

(c) Where a CAIR NOX allowance transfer submitted for recordation fails to meet the requirements of paragraph (a) of this section, the Administrator will not record such transfer.

(2) Unless the permitting authority issues a notification of acceptance of withdrawal of the CAIR NOX opt-in unit from the CAIR NOX Annual Trading Program in accordance with § 96.186 or the unit becomes a CAIR NOX unit under § 96.104, the CAIR NOX opt-in unit shall remain subject to the requirements for a CAIR NOX opt-in unit, even if the CAIR designated representative for the CAIR NOX opt-in unit fails to submit a CAIR permit application that is required for renewal of the CAIR opt-in permit under paragraph (b)(1) of this section.

The permitting authority will issue or deny a CAIR opt-in permit for a unit for which an initial application for a CAIR opt-in permit under § 96.183 is submitted in accordance with the following:

(a) Interim review of monitoring plan. The permitting authority and the Administrator will determine, on an interim basis, the sufficiency of the monitoring plan accompanying the initial application for a CAIR opt-in permit under § 96.183. A monitoring plan is sufficient, for purposes of interim review, if the plan appears to contain information demonstrating that the NOX emissions rate and heat input of the unit and all other applicable parameters are monitored and reported in accordance with subpart HH of this part. A determination of sufficiency shall not be construed as acceptance or approval of the monitoring plan.

(b) Monitoring and reporting. (1)(i) If the permitting authority and the Administrator determine that the monitoring plan is sufficient under paragraph (a) of this section, the owner or operator shall monitor and report the NOX emissions rate and the heat input of the unit and all other applicable parameters, in accordance with subpart HH of this part, starting on the date of certification of the appropriate monitoring systems under subpart HH of this part and continuing until a CAIR opt-in permit is denied under § 96.184(f) or, if a CAIR opt-in permit is issued, the date and time when the unit is withdrawn from the CAIR NOX Annual Trading Program in accordance with § 96.186.

(ii) The monitoring and reporting under paragraph (b)(1)(i) of this section shall include the entire control period immediately before the date on which the unit enters the CAIR NOX Annual Trading Program under § 96.184(g), during which period monitoring system availability must not be less than 90 percent under subpart HH of this part and the unit must be in full compliance with any applicable State or Federal emissions or emissions-related requirements.

(2) To the extent the NOX emissions rate and the heat input of the unit are monitored and reported in accordance with subpart HH of this part for one or more control periods, in addition to the control period under paragraph (b)(1)(ii) of this section, during which control periods monitoring system availability is not less than 90 percent under subpart HH of this part and the unit is in full compliance with any applicable State or Federal emissions or emissions-related requirements and which control periods begin not more than 3 years before the unit enters the CAIR NOX Annual Trading Program under § 96.184(g), such information shall be used as provided in paragraphs (c) and (d) of this section.

(c) Baseline heat input. The unit's baseline heat input shall equal:

(1) If the unit's NOX emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's total heat input (in mmBtu) for the control period; or

(2) If the unit's NOX emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, the average of the amounts of the unit's total heat input (in mmBtu) for the control periods under paragraphs (b)(1)(ii) and (2) of this section.

(d) Baseline NO X emission rate. The unit's baseline NOX emission rate shall equal:

(1) If the unit's NOX emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's NOX emissions rate (in lb/mmBtu) for the control period;

(2) If the unit's NOX emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit does not have add-on NOX emission controls during any such control periods, the average of the amounts of the unit's NOX emissions rate (in lb/mmBtu) for the control periods under paragraphs (b)(1)(ii) and (2) of this section; or

(3) If the unit's NOX emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit has add-on NOX emission controls during any such control periods, the average of the amounts of the unit's NOX emissions rate (in lb/mmBtu) for such control periods during which the unit has add-on NOX emission controls.

(e) Issuance of CAIR opt-in permit. After calculating the baseline heat input and the baseline NOX emissions rate for the unit under paragraphs (c) and (d) of this section and if the permitting authority determines that the CAIR designated representative shows that the unit meets the requirements for a CAIR NOX opt-in unit in § 96.180 and meets the elements certified in § 96.183(a)(2), the permitting authority will issue a CAIR opt-in permit. The permitting authority will provide a copy of the CAIR opt-in permit to the Administrator, who will then establish a compliance account for the source that includes the CAIR NOX opt-in unit unless the source already has a compliance account.

(f) Issuance of denial of CAIR opt-in permit. Notwithstanding paragraphs (a) through (e) of this section, if at any time before issuance of a CAIR opt-in permit for the unit, the permitting authority determines that the CAIR designated representative fails to show that the unit meets the requirements for a CAIR NOX opt-in unit in § 96.180 or meets the elements certified in § 96.183(a)(2), the permitting authority will issue a denial of a CAIR opt-in permit for the unit.

(g) Date of entry into CAIR NO X Annual Trading Program. A unit for which an initial CAIR opt-in permit is issued by the permitting authority shall become a CAIR NOX opt-in unit, and a CAIR NOX unit, as of the later of January 1, 2009 or January 1 of the first control period during which such CAIR opt-in permit is issued.

(h) Repowered CAIR NO X opt-in unit. (1) If CAIR designated representative requests, and the permitting authority issues a CAIR opt-in permit providing for, allocation to a CAIR NOX opt-in unit of CAIR NOX allowances under § 96.188(c) and such unit is repowered after its date of entry into the CAIR NOX Annual Trading Program under paragraph (g) of this section, the repowered unit shall be treated as a CAIR NOX opt-in unit replacing the original CAIR NOX opt-in unit, as of the date of start-up of the repowered unit's combustion chamber.

(2) Notwithstanding paragraphs (c) and (d) of this section, as of the date of start-up under paragraph (h)(1) of this section, the repowered unit shall be deemed to have the same date of commencement of operation, date of commencement of commercial operation, baseline heat input, and baseline NOX emission rate as the original CAIR NOX opt-in unit, and the original CAIR NOX opt-in unit shall no longer be treated as a CAIR NOX opt-in unit or a CAIR NOX unit.

(a) Each CAIR opt-in permit will contain:

(1) All elements required for a complete CAIR permit application under § 96.122;

(2) The certification in § 96.183(a)(2);

(3) The unit's baseline heat input under § 96.184(c);

(4) The unit's baseline NOX emission rate under § 96.184(d);

(5) A statement whether the unit is to be allocated CAIR NOX allowances § 96.188(b) or § 96.188(c) (subject to the conditions in §§ 96.184(h) and 96.186(g));

(6) A statement that the unit may withdraw from the CAIR NOX Annual Trading Program only in accordance with § 96.186; and

(7) A statement that the unit is subject to, and the owners and operators of the unit must comply with, the requirements of § 96.187.

(b) Each CAIR opt-in permit is deemed to incorporate automatically the definitions of terms under § 96.102 and, upon recordation by the Administrator under subpart FF or GG of this part or this subpart, every allocation, transfer, or deduction of CAIR NOX allowances to or from the compliance account of the source that includes a CAIR NOX opt-in unit covered by the CAIR opt-in permit.

(c) The CAIR opt-in permit shall be included, in a format specified by the permitting authority, in the CAIR permit for the source where the CAIR NOX opt-in unit is located and in a title V operating permit or other federally enforceable permit for the source.

Except as provided under paragraph (g) of this section, a CAIR NOX opt-in unit may withdraw from the CAIR NOX Annual Trading Program, but only if the permitting authority issues a notification to the CAIR designated representative of the CAIR NOX opt-in unit of the acceptance of the withdrawal of the CAIR NOX opt-in unit in accordance with paragraph (d) of this section.

(a) Requesting withdrawal. In order to withdraw a CAIR CAIR NOX opt-in unit from the CAIR NOX Annual Trading Program, the CAIR designated representative of the CAIR NOX opt-in unit shall submit to the permitting authority a request to withdraw effective as of midnight of December 31 of a specified calendar year, which date must be at least 4 years after December 31 of the year of entry into the CAIR NOX Annual Trading Program under § 96.184(g). The request must be submitted no later than 90 days before the requested effective date of withdrawal.

(b) Conditions for withdrawal. Before a CAIR NOX opt-in unit covered by a request under paragraph (a) of this section may withdraw from the CAIR NOX Annual Trading Program and the CAIR opt-in permit may be terminated under paragraph (e) of this section, the following conditions must be met:

(1) For the control period ending on the date on which the withdrawal is to be effective, the source that includes the CAIR NOX opt-in unit must meet the requirement to hold CAIR NOX allowances under § 96.106(c) and cannot have any excess emissions.

(2) After the requirement for withdrawal under paragraph (b)(1) of this section is met, the Administrator will deduct from the compliance account of the source that includes the CAIR NOX opt-in unit CAIR NOX allowances equal in amount to and allocated for the same or a prior control period as any CAIR NOX allowances allocated to the CAIR NOX opt-in unit under § 96.188 for any control period for which the withdrawal is to be effective. If there are no remaining CAIR NOX units at the source, the Administrator will close the compliance account, and the owners and operators of the CAIR NOX opt-in unit may submit a CAIR NOX allowance transfer for any remaining CAIR NOX allowances to another CAIR NOX Allowance Tracking System in accordance with subpart GG of this part.

(c) Notification. (1) After the requirements for withdrawal under paragraphs (a) and (b) of this section are met (including deduction of the full amount of CAIR NOX allowances required), the permitting authority will issue a notification to the CAIR designated representative of the CAIR NOX opt-in unit of the acceptance of the withdrawal of the CAIR NOX opt-in unit as of midnight on December 31 of the calendar year for which the withdrawal was requested.

(2) If the requirements for withdrawal under paragraphs (a) and (b) of this section are not met, the permitting authority will issue a notification to the CAIR designated representative of the CAIR NOX opt-in unit that the CAIR NOX opt-in unit's request to withdraw is denied. Such CAIR NOX opt-in unit shall continue to be a CAIR NOX opt-in unit.

(d) Permit amendment. After the permitting authority issues a notification under paragraph (c)(1) of this section that the requirements for withdrawal have been met, the permitting authority will revise the CAIR permit covering the CAIR NOX opt-in unit to terminate the CAIR opt-in permit for such unit as of the effective date specified under paragraph (c)(1) of this section. The unit shall continue to be a CAIR NOX opt-in unit until the effective date of the termination and shall comply with all requirements under the CAIR NOX Annual Trading Program concerning any control periods for which the unit is a CAIR NOX opt-in unit, even if such requirements arise or must be complied with after the withdrawal takes effect.

(e) Reapplication upon failure to meet conditions of withdrawal. If the permitting authority denies the CAIR NOX opt-in unit's request to withdraw, the CAIR designated representative may submit another request to withdraw in accordance with paragraphs (a) and (b) of this section.

(f) Ability to reapply to the CAIR NO X Annual Trading Program. Once a CAIR NOX opt-in unit withdraws from the CAIR NOX Annual Trading Program and its CAIR opt-in permit is terminated under this section, the CAIR designated representative may not submit another application for a CAIR opt-in permit under § 96.183 for such CAIR NOX opt-in unit before the date that is 4 years after the date on which the withdrawal became effective. Such new application for a CAIR opt-in permit will be treated as an initial application for a CAIR opt-in permit under § 96.184.

(g) Inability to withdraw. Notwithstanding paragraphs (a) through (f) of this section, a CAIR NOX opt-in unit shall not be eligible to withdraw from the CAIR NOX Annual Trading Program if the CAIR designated representative of the CAIR NOX opt-in unit requests, and the permitting authority issues a CAIR NOX opt-in permit providing for, allocation to the CAIR NOX opt-in unit of CAIR NOX allowances under § 96.188(c).

(a) Notification. If a CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104, then the CAIR designated representative shall notify in writing the permitting authority and the Administrator of such change in the CAIR NOX opt-in unit's regulatory status, within 30 days of such change.

(b) Permitting authority's and Administrator's actions. (1) If a CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104, the permitting authority will revise the CAIR NOX opt-in unit's CAIR opt-in permit to meet the requirements of a CAIR permit under § 96.123, and remove the CAIR opt-in permit provisions, as of the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104.

(2)(i) The Administrator will deduct from the compliance account of the source that includes the CAIR NOX opt-in unit that becomes a CAIR NOX unit under § 96.104, CAIR NOX allowances equal in amount to and allocated for the same or a prior control period as:

(A) Any CAIR NOX allowances allocated to the CAIR NOX opt-in unit under § 96.188 for any control period after the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104; and

(B) If the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104 is not December 31, the CAIR NOX allowances allocated to the CAIR NOX opt-in unit under § 96.188 for the control period that includes the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104, multiplied by the ratio of the number of days, in the control period, starting with the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104 divided by the total number of days in the control period and rounded to the nearest whole allowance as appropriate.

(ii) The CAIR designated representative shall ensure that the compliance account of the source that includes the CAIR NOX opt-in unit that becomes a CAIR NOX unit under § 96.104 contains the CAIR NOX allowances necessary for completion of the deduction under paragraph (b)(2)(i) of this section.

(3)(i) For every control period after the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104, the CAIR NOX opt-in unit will be allocated CAIR NOX allowances under § 96.142.

(ii) If the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104 is not December 31, the following amount of CAIR NOX allowances will be allocated to the CAIR NOX opt-in unit (as a CAIR NOX unit) under § 96.142 for the control period that includes the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104:

(A) The amount of CAIR NOX allowances otherwise allocated to the CAIR NOX opt-in unit (as a CAIR NOX unit) under § 96.142 for the control period multiplied by;

(B) The ratio of the number of days, in the control period, starting with the date on which the CAIR NOX opt-in unit becomes a CAIR NOX unit under § 96.104, divided by the total number of days in the control period; and

(C) Rounded to the nearest whole allowance as appropriate.

(a) Timing requirements. (1) When the CAIR opt-in permit is issued under § 96.184(e), the permitting authority will allocate CAIR NOX allowances to the CAIR NOX opt-in unit, and submit to the Administrator the allocation for the control period in which a CAIR NOX opt-in unit enters the CAIR NOX Annual Trading Program under § 96.184(g), in accordance with paragraph (b) or (c) of this section.

(2) By no later than October 31 of the control period after the control period in which a CAIR NOX opt-in unit enters the CAIR NOX Annual Trading Program under § 96.184(g) and October 31 of each year thereafter, the permitting authority will allocate CAIR NOX allowances to the CAIR NOX opt-in unit, and submit to the Administrator the allocation for the control period that includes such submission deadline and in which the unit is a CAIR NOX opt-in unit, in accordance with paragraph (b) or (c) of this section.

(b) Calculation of allocation. For each control period for which a CAIR NOX opt-in unit is to be allocated CAIR NOX allowances, the permitting authority will allocate in accordance with the following procedures:

(1) The heat input (in mmBtu) used for calculating the CAIR NOX allowance allocation will be the lesser of:

(i) The CAIR NOX opt-in unit's baseline heat input determined under § 96.184(c); or

(ii) The CAIR NOX opt-in unit's heat input, as determined in accordance with subpart HH of this part, for the immediately prior control period, except when the allocation is being calculated for the control period in which the CAIR NOX opt-in unit enters the CAIR NOX Annual Trading Program under § 96.184(g).

(2) In 2011 and each year thereafter, after Administrator has completed all deductions under § 96.254(b), the Administrator will record in the compliance account any CAIR SO2 allowance allocated to any CAIR SO2 unit at the source for the new 30th year (i.e., the year that is 30 years after the calendar year for which such deductions are or could be made) and any CAIR SO2 allowance allocated for the new 30th year and transferred to the source in accordance with subpart GGG of this part or subpart D of part 73 of this chapter.

(b)(1) After a general account is established under § 96.251(b) or § 73.31(c) of this chapter, the Administrator will record in the general account any CAIR SO2 allowance allocated for each of the 30 years starting the later of 2010 or the year in which the general account is established and transferred to the general account in accordance with subpart GGG of this part or subpart D of part 73 of this chapter.

(2) In 2011 and each year thereafter, after Administrator has completed all deductions under § 96.254(b), the Administrator will record in the general account any CAIR SO2 allowance allocated for the new 30th year (i.e., the year that is 30 years after the calendar year for which such deductions are or could be made) and transferred to the general account in accordance with subpart GGG of this part or subpart D of part 73 of this chapter.

(c) Serial numbers for allocated CAIR SO 2 allowances. When recording the allocation of CAIR SO2 allowances issued by a permitting authority under § 96.288, the Administrator will assign each such CAIR SO2 allowance a unique identification number that will include digits identifying the year of the control period for which the CAIR SO2 allowance is allocated.

(a) Allowance transfer deadline. The CAIR SO2 allowances are available to be deducted for compliance with a source's CAIR SO2 emissions limitation for a control period in a given calendar year only if the CAIR SO2 allowances:

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

(2) Are held in the compliance account as of the allowance transfer deadline for the control period or are transferred into the compliance account by a CAIR SO2 allowance transfer correctly submitted for recordation under §§ 96.260 and 96.261 by the allowance transfer deadline for the control period.

(b) Deductions for compliance. Following the recordation, in accordance with § 96.261, of CAIR SO2 allowance transfers submitted for recordation in a source's compliance account by the allowance transfer deadline for a control period, the Administrator will deduct from the compliance account CAIR SO2 allowances available under paragraph (a) of this section in order to determine whether the source meets the CAIR SO2 emissions limitation for the control period as follows:

(1) For a CAIR SO2 source subject to an Acid Rain emissions limitation, the Administrator will, in the following order:

(i) Deduct the amount of CAIR SO2 allowances, available under paragraph (a) of this section and not issued by a permitting authority under § 96.288, that is required under §§ 73.35(b) and (c) of this part. If there are sufficient CAIR SO2 allowances to complete this deduction, the deduction will be treated as satisfying the requirements of §§ 73.35(b) and (c) of this chapter.

(ii) Deduct the amount of CAIR SO2 allowances, not issued by a permitting authority under § 96.288, that is required under §§ 73.35(d) and 77.5 of this part. If there are sufficient CAIR SO2 allowances to complete this deduction, the deduction will be treated as satisfying the requirements of §§ 73.35(d) and 77.5 of this chapter.

(iii) Treating the CAIR SO2 allowances deducted under paragraph (b)(1)(i) of this section as also being deducted under this paragraph (b)(1)(iii), deduct CAIR SO2 allowances available under paragraph (a) of this section (including any issued by a permitting authority under § 96.288) in order to determine whether the source meets the CAIR SO2 emissions limitation for the control period, as follows:

(A) Until the tonnage equivalent of the CAIR SO2 allowances deducted equals, or exceeds in accordance with paragraphs (c)(1) and (2) of this section, the number of tons of total sulfur dioxide emissions, determined in accordance with subpart HHH of this part, from all CAIR SO2 units at the source for the control period; or

(B) If there are insufficient CAIR SO2 allowances to complete the deductions in paragraph (b)(1)(iii)(A) of this section, until no more CAIR SO2 allowances available under paragraph (a) of this section (including any issued by a permitting authority under § 96.288) remain in the compliance account.

(2) For a CAIR SO2 source not subject to an Acid Rain emissions limitation, the Administrator will deduct CAIR SO2 allowances available under paragraph (a) of this section (including any issued by a permitting authority under § 96.288) in order to determine whether the source meets the CAIR SO2 emissions limitation for the control period, as follows:

(i) Until the tonnage equivalent of the CAIR SO2 allowances deducted equals, or exceeds in accordance with paragraphs (c)(1) and (2) of this section, the number of tons of total sulfur dioxide emissions, determined in accordance with subpart HHH of this part, from all CAIR SO2 units at the source for the control period; or

(ii) If there are insufficient CAIR SO2 allowances to complete the deductions in paragraph (b)(2)(i) of this section, until no more CAIR SO2 allowances available under paragraph (a) of this section (including any issued by a permitting authority under § 96.288) remain in the compliance account.

(c)(1) Identification of CAIR SO 2 allowances by serial number. The CAIR authorized account representative for a source's compliance account may request that specific CAIR SO2 allowances, identified by serial number, in the compliance account be deducted for emissions or excess emissions for a control period in accordance with paragraph (b) or (d) of this section. Such request shall be submitted to the Administrator by the allowance transfer deadline for the control period and include, in a format prescribed by the Administrator, the identification of the CAIR SO2 source and the appropriate serial numbers.

(2) First-in, first-out. The Administrator will deduct CAIR SO2 allowances under paragraph (b) or (d) of this section from the source's compliance account, in the absence of an identification or in the case of a partial identification of CAIR SO2 allowances by serial number under paragraph (c)(1) of this section, on a first-in, first-out (FIFO) accounting basis in the following order:

(i) Any CAIR SO2 allowances that were allocated to the units at the source for a control period before 2010, in the order of recordation;

(ii) Any CAIR SO2 allowances that were allocated to any entity for a control period before 2010 and transferred and recorded in the compliance account pursuant to subpart GGG of this part or subpart D of part 73 of this chapter, in the order of recordation;

(iii) Any CAIR SO2 allowances that were allocated to the units at the source for a control period during 2010 through 2014, in the order of recordation;

(iv) Any CAIR SO2 allowances that were allocated to any entity for a control period during 2010 through 2014 and transferred and recorded in the compliance account pursuant to subpart GGG of this part or subpart D of part 73 of this chapter, in the order of recordation;

(v) Any CAIR SO2 allowances that were allocated to the units at the source for a control period in 2015 or later, in the order of recordation; and

(vi) Any CAIR SO2 allowances that were allocated to any entity for a control period in 2015 or later and transferred and recorded in the compliance account pursuant to subpart GGG of this part or subpart D of part 73 of this chapter, in the order of recordation.

(d) Deductions for excess emissions. (1) After making the deductions for compliance under paragraph (b) of this section for a control period in a calendar year in which the CAIR SO2 source has excess emissions, the Administrator will deduct from the source's compliance account the tonnage equivalent in CAIR SO2 allowances, allocated for the control period in the immediately following calendar year (including any issued by a permitting authority under § 96.288), equal to, or exceeding in accordance with paragraphs (c)(1) and (2) of this section, 3 times the following amount: the number of tons of the source's excess emissions minus, if the source is subject to an Acid Rain emissions limitation, the amount of the CAIR SO2 allowances required to be deducted under paragraph (b)(1)(ii) of this section.

(2) Any allowance deduction required under paragraph (d)(1) of this section shall not affect the liability of the owners and operators of the CAIR SO2 source or the CAIR SO2 units at the source for any fine, penalty, or assessment, or their obligation to comply with any other remedy, for the same violations, as ordered under the Clean Air Act or applicable State law.

(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 and subpart III.

(f) Administrator's action on submissions. (1) The Administrator may review and conduct independent audits concerning any submission under the CAIR SO2 Trading Program and make appropriate adjustments of the information in the submissions.

(2) The Administrator may deduct CAIR SO2 allowances from or transfer CAIR SO2 allowances to a source's compliance account based on the information in the submissions, as adjusted under paragraph (f)(1) of this section, and record such deductions and transfers.

(a) CAIR SO2 allowances may be banked for future use or transfer in a compliance account or a general account in accordance with paragraph (b) of this section.

(b) Any CAIR SO2 allowance that is held in a compliance account or a general account will remain in such account unless and until the CAIR SO2 allowance is deducted or transferred under § 96.254, § 96.256, or subpart GGG or III of this part.

The Administrator may, at his or her sole discretion and on his or her own motion, correct any error in any CAIR SO2 Allowance Tracking System account. Within 10 business days of making such correction, the Administrator will notify the CAIR authorized account representative for the account.

(a) The CAIR authorized account representative of a general account may submit to the Administrator a request to close the account, which shall include a correctly submitted allowance transfer under §§ 96.260 and 96.261 for any CAIR SO2 allowances in the account to one or more other CAIR SO2 Allowance Tracking System accounts.

(b) If a general account has no allowance transfers in or out of the account for a 12-month period or longer and does not contain any CAIR SO2 allowances, the Administrator may notify the CAIR authorized account representative for the account that the account will be closed following 20 business days after the notice is sent. The account will be closed after the 20-day period unless, before the end of the 20-day period, the Administrator receives a correctly submitted transfer of CAIR SO2 allowances into the account under §§ 96.260 and 96.261 or a statement submitted by the CAIR authorized account representative demonstrating to the satisfaction of the Administrator good cause as to why the account should not be closed.

(a) A CAIR authorized account representative seeking recordation of a CAIR SO2 allowance transfer shall submit the transfer to the Administrator. To be considered correctly submitted, the CAIR SO2 allowance transfer shall include the following elements, in a format specified by the Administrator:

(1) The account numbers of both the transferor and transferee accounts;

(2) The serial number of each CAIR SO2 allowance that is in the transferor account and is to be transferred; and

(3) The name and signature of the CAIR authorized account representatives of the transferor and transferee accounts and the dates signed.

(b)(1) The CAIR authorized account representative for the transferee account can meet the requirements in paragraph (a)(3) of this section by submitting, in a format prescribed by the Administrator, a statement signed by the CAIR authorized account representative and identifying each account into which any transfer of allowances, submitted on or after the date on which the Administrator receives such statement, is authorized. Such authorization shall be binding on any CAIR authorized account representative for such account and shall apply to all transfers into the account that are submitted on or after such date of receipt, unless and until the Administrator receives a statement signed by the CAIR authorized account representative retracting the authorization for the account.

(2) The statement under paragraph (b)(1) of this section shall include the following: “By this signature I authorize any transfer of allowances into each account listed herein, except that I do not waive any remedies under State or Federal law to obtain correction of any erroneous transfers into such accounts. This authorization shall be binding on any CAIR authorized account representative for such account unless and until a statement signed by the CAIR authorized account representative retracting this authorization for the account is received by the Administrator.”

(a) Within 5 business days (except as necessary to perform a transfer in perpetuity of CAIR SO2 allowances allocated to a CAIR SO2 unit or as provided in paragraph (b) of this section) of receiving a CAIR SO2 allowance transfer, the Administrator will record a CAIR SO2 allowance transfer by moving each CAIR SO2 allowance from the transferor account to the transferee account as specified by the request, provided that:

(1) The transfer is correctly submitted under § 96.260;

(2) The transferor account includes each CAIR SO2 allowance identified by serial number in the transfer; and

(3) The transfer is in accordance with the limitation on transfer under § 74.42 of this chapter and § 74.47(c) of this chapter, as applicable.

(b) A CAIR SO2 allowance transfer that is submitted for recordation after the allowance transfer deadline for a control period and that includes any CAIR SO2 allowances allocated for any control period before such allowance transfer deadline will not be recorded until after the Administrator completes the deductions under § 96.254 for the control period immediately before such allowance transfer deadline.

(c) Where a CAIR SO2 allowance transfer submitted for recordation fails to meet the requirements of paragraph (a) of this section, the Administrator will not record such transfer.

(a) Notification of recordation. Within 5 business days of recordation of a CAIR SO2 allowance transfer under § 96.261, the Administrator will notify the CAIR authorized account representatives of both the transferor and transferee accounts.

(b) Notification of non-recordation. Within 10 business days of receipt of a CAIR SO2 allowance transfer that fails to meet the requirements of § 96.261(a), the Administrator will notify the CAIR authorized account representatives of both accounts subject to the transfer of:

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

(2) The reasons for such non-recordation.

(c) Nothing in this section shall preclude the submission of a CAIR SO2 allowance transfer for recordation following notification of non-recordation.

The owners and operators, and to the extent applicable, the CAIR designated representative, of a CAIR SO2 unit, shall comply with the monitoring, recordkeeping, and reporting requirements as provided in this subpart and in subparts F and G of part 75 of this chapter. For purposes of complying with such requirements, the definitions in § 96.202 and in § 72.2 of this chapter shall apply, and the terms “affected unit,” “designated representative,” and “continuous emission monitoring system” (or “CEMS”) in part 75 of this chapter shall be deemed to refer to the terms “CAIR SO2 unit,” “CAIR designated representative,” and “continuous emission monitoring system” (or “CEMS”) respectively, as defined in § 96.202.

(1) If the unit's SO2 emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's total heat input (in mmBtu) for the control period; or

(2) If the unit's SO2 emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, the average of the amounts of the unit's total heat input (in mmBtu) for the control periods under paragraphs (b)(1)(ii) and (2) of this section and the control periods under paragraph (b)(2) of this section.

(d) Baseline SO 2 emission rate. The unit's baseline SO2 emission rate shall equal:

(1) If the unit's SO2 emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's SO2 emissions rate (in lb/mmBtu) for the control period;

(2) If the unit's SO2 emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit does not have add-on SO2 emission controls during any such control periods, the average of the amounts of the unit's SO2 emissions rate (in lb/mmBtu) for the control periods under paragraphs (b)(1)(ii) and (2) of this section; or

(3) If the unit's SO2 emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit has add-on SO2 emission controls during any such control periods, the average of the amounts of the unit's SO2 emissions rate (in lb/mmBtu) for such control periods during which the unit has add-on SO2 emission controls.

(e) Issuance of CAIR opt-in permit. After calculating the baseline heat input and the baseline SO2 emissions rate for the unit under paragraphs (c) and (d) of this section and if the permitting authority determines that the CAIR designated representative shows that the unit meets the requirements for a CAIR SO2 opt-in unit in § 96.280 and meets the elements certified in § 96.283(a)(2), the permitting authority will issue a CAIR opt-in permit. The permitting authority will provide a copy of the CAIR opt-in permit to the Administrator, who will then establish a compliance account for the source that includes the CAIR SO2 opt-in unit unless the source already has a compliance account.

(f) Issuance of denial of CAIR opt-in permit. Notwithstanding paragraphs (a) through (e) of this section, if at any time before issuance of a CAIR opt-in permit for the unit, the permitting authority determines that the CAIR designated representative fails to show that the unit meets the requirements for a CAIR SO2 opt-in unit in § 96.280 or meets the elements certified in § 96.283(a)(2), the permitting authority will issue a denial of a CAIR opt-in permit for the unit.

(g) Date of entry into CAIR SO 2 Trading Program. A unit for which an initial CAIR opt-in permit is issued by the permitting authority shall become a CAIR SO2 opt-in unit, and a CAIR SO2 unit, as of the later of January 1, 2010 or January 1 of the first control period during which such CAIR opt-in permit is issued.

(h) Repowered CAIR SO 2 opt-in unit. (1) If CAIR designated representative requests, and the permitting authority issues a CAIR opt-in permit providing for, allocation to a CAIR SO2 opt-in unit of CAIR SO2 allowances under § 96.288(c) and such unit is repowered after its date of entry into the CAIR SO2 Trading Program under paragraph (g) of this section, the repowered unit shall be treated as a CAIR SO2 opt-in unit replacing the original CAIR SO2 opt-in unit, as of the date of start-up of the repowered unit's combustion chamber.

(2) Notwithstanding paragraphs (c) and (d) of this section, as of the date of start-up under paragraph (h)(1) of this section, the repowered unit shall be deemed to have the same date of commencement of operation, date of commencement of commercial operation, baseline heat input, and baseline SO2 emission rate as the original CAIR SO2 opt-in unit, and the original CAIR SO2 opt-in unit shall no longer be treated as a CAIR SO2 opt-in unit or a CAIR SO2 unit.

(a) Each CAIR opt-in permit will contain:

(1) All elements required for a complete CAIR permit application under § 96.222;

(2) The certification in § 96.283(a)(2);

(b) Each CAIR opt-in permit is deemed to incorporate automatically the definitions of terms under § 96.202 and, upon recordation by the Administrator under subpart FFF or GGG of this part or this subpart, every allocation, transfer, or deduction of CAIR SO2 allowances to or from the compliance account of the source that includes a CAIR SO2 opt-in unit covered by the CAIR opt-in permit.

(c) The CAIR opt-in permit shall be included, in a format specified by the permitting authority, in the CAIR permit for the source where the CAIR SO2 opt-in unit is located and in a title V operating permit or other federally enforceable permit for the source.

Except as provided under paragraph (g) of this section, a CAIR SO2 opt-in unit may withdraw from the CAIR SO2 Trading Program, but only if the permitting authority issues a notification to the CAIR designated representative of the CAIR SO2 opt-in unit of the acceptance of the withdrawal of the CAIR SO2 opt-in unit in accordance with paragraph (d) of this section.

(a) Requesting withdrawal. In order to withdraw a CAIR SO2 opt-in unit from the CAIR SO2 Trading Program, the CAIR designated representative of the CAIR SO2 opt-in unit shall submit to the permitting authority a request to withdraw effective as of midnight of December 31 of a specified calendar year, which date must be at least 4 years after December 31 of the year of entry into the CAIR SO2 Trading Program under § 96.284(g). The request must be submitted no later than 90 days before the requested effective date of withdrawal.

(b) Conditions for withdrawal. Before a CAIR SO2 opt-in unit covered by a request under paragraph (a) of this section may withdraw from the CAIR SO2 Trading Program and the CAIR opt-in permit may be terminated under paragraph (e) of this section, the following conditions must be met:

(1) For the control period ending on the date on which the withdrawal is to be effective, the source that includes the CAIR SO2 opt-in unit must meet the requirement to hold CAIR SO2 allowances under § 96.206(c) and cannot have any excess emissions.

(2) After the requirement for withdrawal under paragraph (b)(1) of this section is met, the Administrator will deduct from the compliance account of the source that includes the CAIR SO2 opt-in unit CAIR SO2 allowances equal in amount to and allocated for the same or a prior control period as any CAIR SO2 allowances allocated to the CAIR SO2 opt-in unit under § 96.288 for any control period for which the withdrawal is to be effective. If there are no remaining CAIR SO2 units at the source, the Administrator will close the compliance account, and the owners and operators of the CAIR SO2 opt-in unit may submit a CAIR SO2 allowance transfer for any remaining CAIR SO2 allowances to another CAIR SO2 Allowance Tracking System in accordance with subpart GGG of this part.

(c) Notification. (1) After the requirements for withdrawal under paragraphs (a) and (b) of this section are met (including deduction of the full amount of CAIR SO2 allowances required), the permitting authority will issue a notification to the CAIR designated representative of the CAIR SO2 opt-in unit of the acceptance of the withdrawal of the CAIR SO2 opt-in unit as of midnight on December 31 of the calendar year for which the withdrawal was requested.

(2) If the requirements for withdrawal under paragraphs (a) and (b) of this section are not met, the permitting authority will issue a notification to the CAIR designated representative of the CAIR SO2 opt-in unit that the CAIR SO2 opt-in unit's request to withdraw is denied. Such CAIR SO2 opt-in unit shall continue to be a CAIR SO2 opt-in unit.

(d) Permit amendment. After the permitting authority issues a notification under paragraph (c)(1) of this section that the requirements for withdrawal have been met, the permitting authority will revise the CAIR permit covering the CAIR SO2 opt-in unit to terminate the CAIR opt-in permit for such unit as of the effective date specified under paragraph (c)(1) of this section. The unit shall continue to be a CAIR SO2 opt-in unit until the effective date of the termination and shall comply with all requirements under the CAIR SO2 Trading Program concerning any control periods for which the unit is a CAIR SO2 opt-in unit, even if such requirements arise or must be complied with after the withdrawal takes effect.

(e) Reapplication upon failure to meet conditions of withdrawal. If the permitting authority denies the CAIR SO2 opt-in unit's request to withdraw, the CAIR designated representative may submit another request to withdraw in accordance with paragraphs (a) and (b) of this section.

(f) Ability to reapply to the CAIR SO 2 Trading Program. Once a CAIR SO2 opt-in unit withdraws from the CAIR SO2 Trading Program and its CAIR opt-in permit is terminated under this section, the CAIR designated representative may not submit another application for a CAIR opt-in permit under § 96.283 for such CAIR SO2 opt-in unit before the date that is 4 years after the date on which the withdrawal became effective. Such new application for a CAIR opt-in permit will be treated as an initial application for a CAIR opt-in permit under § 96.284.

(g) Inability to withdraw. Notwithstanding paragraphs (a) through (f) of this section, a CAIR SO2 opt-in unit shall not be eligible to withdraw from the CAIR SO2 Trading Program if the CAIR designated representative of the CAIR SO2 opt-in unit requests, and the permitting authority issues a CAIR opt-in permit providing for, allocation to the CAIR SO2 opt-in unit of CAIR SO2 allowances under § 96.288(c).

(a) Timing requirements. (1) When the CAIR opt-in permit is issued under § 96.284(e), the permitting authority will allocate CAIR SO2 allowances to the CAIR SO2 opt-in unit, and submit to the Administrator the allocation for the control period in which a CAIR SO2 opt-in unit enters the CAIR SO2 Trading Program under § 96.284(g), in accordance with paragraph (b) or (c) of this section.

(2) By no later than October 31 of the control period after the control period in which a CAIR SO2 opt-in unit enters the CAIR SO2 Trading Program under § 96.284(g) and October 31 of each year thereafter, the permitting authority will allocate CAIR SO2 allowances to the CAIR SO2 opt-in unit, and submit to the Administrator the allocation for the control period that includes such submission deadline and in which the unit is a CAIR SO2 opt-in unit, in accordance with paragraph (b) or (c) of this section.

(b) Calculation of allocation. For each control period for which a CAIR SO2 opt-in unit is to be allocated CAIR SO2 allowances, the permitting authority will allocate in accordance with the following procedures:

(1) The heat input (in mmBtu) used for calculating the CAIR SO2 allowance allocation will be the lesser of:

(i) The CAIR SO2 opt-in unit's baseline heat input determined under § 96.284(c); or

(ii) The CAIR SO2 opt-in unit's heat input, as determined in accordance with subpart HHH of this part, for the immediately prior control period, except when the allocation is being calculated for the control period in which the CAIR SO2 opt-in unit enters the CAIR SO2 Trading Program under § 96.284(g).

(2) The SO2 emission rate (in lb/mmBtu) used for calculating CAIR SO2 allowance allocations will be the lesser of:

(i) The CAIR SO2 opt-in unit's baseline SO2 emissions rate (in lb/mmBtu) determined under § 96.284(d) and multiplied by 70 percent; or

(ii) The most stringent State or Federal SO2 emissions limitation applicable to the CAIR SO2 opt-in unit at any time during the control period for which CAIR SO2 allowances are to be allocated.

(3) The permitting authority will allocate CAIR SO2 allowances to the CAIR SO2 opt-in unit with a tonnage equivalent equal to, or less than by the smallest possible amount, the heat input under paragraph (b)(1) of this section, multiplied by the SO2 emission rate under paragraph (b)(2) of this section, and divided by 2,000 lb/ton.

(c) Notwithstanding paragraph (b) of this section and if the CAIR designated representative requests, and the permitting authority issues a CAIR opt-in permit (based on a demonstration of the intent to repower stated under § 96.283(a)(5)) providing for, allocation to a CAIR SO2 opt-in unit of CAIR SO2 allowances under this paragraph (subject to the conditions in §§ 96.284(h) and 96.286(g)), the permitting authority will allocate to the CAIR SO2 opt-in unit as follows:

(1) For each control period in 2010 through 2014 for which the CAIR SO2 opt-in unit is to be allocated CAIR SO2 allowances,

(i) The heat input (in mmBtu) used for calculating CAIR SO2 allowance allocations will be determined as described in paragraph (b)(1) of this section.

(ii) The SO2 emission rate (in lb/mmBtu) used for calculating CAIR SO2 allowance allocations will be the lesser of:

(A) The CAIR SO2 opt-in unit's baseline SO2 emissions rate (in lb/mmBtu) determined under § 96.284(d); or

(B) Incomplete application notice. If the certification application is not complete, then the permitting authority will issue a written notice of incompleteness that sets a reasonable date by which the CAIR designated representative must submit the additional information required to complete the certification application. If the CAIR designated representative does not comply with the notice of incompleteness by the specified date, then the permitting authority may issue a notice of disapproval under paragraph (d)(3)(iv)(C) of this section. The 120-day review period shall not begin before receipt of a complete certification application.

(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 permitting authority 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 permitting authority 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). The owner or operator shall follow the procedures for loss of certification in paragraph (d)(3)(v) of this section for each monitoring system that is disapproved for initial certification.

(D) Audit decertification. The permitting authority or, for a CAIR NOX Ozone Season opt-in unit or a unit for which a CAIR opt-in permit application is submitted and not withdrawn and a CAIR opt-in permit is not yet issued or denied under subpart IIII of this part, the Administrator may issue a notice of disapproval of the certification status of a monitor in accordance with § 96.372(b).

(v) Procedures for loss of certification. If the permitting authority or 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 NOX emission rate (i.e., NOX-diluent) system, the maximum potential NOX emission rate, as defined in § 72.2 of this chapter.

(2) For a disapproved NOX pollutant concentration monitor and disapproved flow monitor, respectively, the maximum potential concentration of NOX and the maximum potential flow rate, as defined in sections 2.1.2.1 and 2.1.4.1 of appendix A to part 75 of this chapter.

(3) 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.

(4) 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.

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

(e) Initial certification and recertification procedures for units using the low mass emission excepted methodology under § 75.19 of this chapter. 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) Certification/recertification procedures for alternative monitoring systems. The CAIR designated representative of each unit for which the owner or operator intends to use an alternative monitoring system approved by the Administrator and, if applicable, the permitting authority 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) 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 or subpart H of, or appendix D or appendix E 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 § 96.371 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 permitting authority or, for a CAIR NOX Ozone Season opt-in unit or a unit for which a CAIR opt-in permit application is submitted and not withdrawn and a CAIR opt-in permit is not yet issued or denied under subpart IIII of this part, 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 permitting authority or the Administrator. By issuing the notice of disapproval, the permitting authority or 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 § 96.371 for each disapproved monitoring system.

The CAIR designated representative for a CAIR NOX Ozone Season unit shall submit written notice to the permitting authority and the Administrator in accordance with § 75.61 of this chapter.

Such CAIR NOX Ozone Season opt-in unit shall continue to be a CAIR NOX Ozone Season opt-in unit.

(d) Permit amendment. After the permitting authority issues a notification under paragraph (c)(1) of this section that the requirements for withdrawal have been met, the permitting authority will revise the CAIR permit covering the CAIR NOX Ozone Season opt-in unit to terminate the CAIR opt-in permit for such unit as of the effective date specified under paragraph (c)(1) of this section. The unit shall continue to be a CAIR NOX Ozone Season opt-in unit until the effective date of the termination and shall comply with all requirements under the CAIR NOX Ozone Season Trading Program concerning any control periods for which the unit is a CAIR NOX Ozone Season opt-in unit, even if such requirements arise or must be complied with after the withdrawal takes effect.

(e) Reapplication upon failure to meet conditions of withdrawal. If the permitting authority denies the CAIR NOX Ozone Season opt-in unit's request to withdraw, the CAIR designated representative may submit another request to withdraw in accordance with paragraphs (a) and (b) of this section.

(f) Ability to reapply to the CAIR NO X Ozone Season Trading Program. Once a CAIR NOX Ozone Season opt-in unit withdraws from the CAIR NOX Ozone Season Trading Program and its CAIR opt-in permit is terminated under this section, the CAIR designated representative may not submit another application for a CAIR opt-in permit under § 96.383 for such CAIR NOX Ozone Season opt-in unit before the date that is 4 years after the date on which the withdrawal became effective. Such new application for a CAIR opt-in permit will be treated as an initial application for a CAIR opt-in permit under § 96.384.

(g) Inability to withdraw. Notwithstanding paragraphs (a) through (f) of this section, a CAIR NOX Ozone Season opt-in unit shall not be eligible to withdraw from the CAIR NOX Ozone Season Trading Program if the CAIR designated representative of the CAIR NOX Ozone Season opt-in unit requests, and the permitting authority issues a CAIR opt-in permit providing for, allocation to the CAIR NOX Ozone Season opt-in unit of CAIR NOX Ozone Season allowances under § 96.388(c).

(a) Notification. If a CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304, then the CAIR designated representative shall notify in writing the permitting authority and the Administrator of such change in the CAIR NOX Ozone Season opt-in unit's regulatory status, within 30 days of such change.

(b) Permitting authority's and Administrator's actions. (1) If a CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304, the permitting authority will revise the CAIR NOX Ozone Season opt-in unit's CAIR opt-in permit to meet the requirements of a CAIR permit under § 96.323, and remove the CAIR opt-in permit provisions, as of the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304.

(2)(i) The Administrator will deduct from the compliance account of the source that includes the CAIR NOX Ozone Season opt-in unit that becomes a CAIR NOX Ozone Season unit under § 96.304, CAIR NOX Ozone Season allowances equal in amount to and allocated for the same or a prior control period as:

(A) Any CAIR NOX Ozone Season allowances allocated to the CAIR NOX Ozone Season opt-in unit under § 96.388 for any control period after the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304; and

(B) If the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304 is not September 30, the CAIR NOX Ozone Season allowances allocated to the CAIR NOX Ozone Season opt-in unit under § 96.388 for the control period that includes the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304, multiplied by the ratio of the number of days, in the control period, starting with the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304 divided by the total number of days in the control period and rounded to the nearest whole allowance as appropriate.

(ii) The CAIR designated representative shall ensure that the compliance account of the source that includes the CAIR NOX Ozone Season opt-in unit that becomes a CAIR NOX Ozone Season unit under § 96.304 contains the CAIR NOX Ozone Season allowances necessary for completion of the deduction under paragraph (b)(2)(i) of this section.

(3)(i) For every control period after the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304, the CAIR NOX Ozone Season opt-in unit will be allocated CAIR NOX Ozone Season allowances under § 96.342.

(ii) If the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304 is not September 30, the following amount of CAIR NOX Ozone Season allowances will be allocated to the CAIR NOX Ozone Season opt-in unit (as a CAIR NOX Ozone Season unit) under § 96.342 for the control period that includes the date on which the CAIR NOX Ozone Season opt-in unit becomes a CAIR NOX Ozone Season unit under § 96.304:

(A) The amount of CAIR NOX Ozone Season allowances otherwise allocated to the CAIR NOX Ozone Season opt-in unit (as a CAIR NOX Ozone Season unit) under § 96.342 for the control period multiplied by;
