(c) By April 1, 2010, by April 1 of 2015, and thereafter by April 1 of the year that is 5 years after the last year for which NOX allowances allocations are determined, the Administrator will determine by order the NOX allowance allocations, in accordance with §§ 97.42(a) through (c), for the control periods in the years that are 3, 4, 5, 6, and 7 years after the applicable deadline under this paragraph (c).

(d) By April 1, 2004 and April 1 of each year thereafter, the Administrator will determine by order the NOX allowance allocations, in accordance with § 97.42(d), for the control period in the year of the applicable deadline under this paragraph (d).

(e) The Administrator will make available to the public each determination of NOX allowance allocations under paragraph (b), (c), or (d) of this section and will provide an opportunity for submission of objections to the determination. Objections shall be limited to addressing whether the determination is in accordance with § 97.42. Based on any such objections, the Administrator will adjust each determination to the extent necessary to ensure that it is in accordance with § 97.42.

(a)(1) The heat input (in mmBtu) used for calculating NOX allowance allocations for each NOX Budget unit under § 97.4(a) will be:

(i) For a NOX allowance allocation under § 97.41(a):

(A) For a unit under § 97.4(a)(1), the average of the two highest amounts of the unit's heat input for the control periods in 1995 through 1998; or

(B) For a unit under § 97.4(a)(2), the control period in 1995 or, if the Administrator determines that reasonably reliable data are available for control periods in 1996 through 1998, the average of the two highest amounts of the unit's heat input for the control periods in 1995 through 1998.

(ii) For a NOX allowance allocation under § 97.41(b), the unit's average heat input for the control periods in 2002 through 2004.

(iii) For a NOX allowance allocation under § 97.41(c), the unit's average heat input for the control period in the years that are 4, 5, 6, 7, and 8 years before the first year for which the allocation is being calculated.

(2) The unit's heat input for the control period in each year specified under paragraph (a)(1) of this section will be determined in accordance with part 75 of this chapter. Notwithstanding the first sentence of this paragraph (a)(2):

(i) For a NOX allowance allocation under § 97.41(a), such heat input will be determined using the best available data reported to the Administrator for the unit if the unit was not otherwise subject to the requirements of part 75 of this chapter for the control period.

(ii) For a NOX allowance allocation under § 97.41(b) or (c) for a unit exempt under § 97.4(b), such heat input shall be treated as zero if the unit is exempt under § 97.4(b) during the control period.

(b) For each group of control periods specified in § 97.41(a) through (c), the Administrator will allocate to all NOX Budget units in a given State under § 97.4(a)(1) that commenced operation before May 1, 1997 for allocations under § 97.41(a), May 1, 2003 for allocations under § 97.41(b), and May 1 of the year 5 years before the first year for which the allocation under § 97.41(c) is being calculated, a total number of NOX allowances equal to 95 percent of the portion of the State's trading program budget under § 97.40 covering such units. The Administrator will allocate in accordance with the following procedures:

(1) The Administrator will allocate NOX allowances to each NOX Budget unit under § 97.4(a)(1) for each control period in an amount equaling 0.15 lb/mmBtu multiplied by the heat input determined under paragraph (a) of this section, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate.

(2) If the initial total number of NOX allowances allocated to all NOX Budget units under § 97.4(a)(1) in the State for a control period under paragraph (b)(1) of this section does not equal 95 percent of the portion of the State's trading program budget under § 97.40 covering such units, the Administrator will adjust the total number of NOX allowances allocated to all such NOX Budget units for the control period under paragraph (b)(1) of this section so that the total number of NOX allowances allocated equals 95 percent of such portion of the State's trading program budget. This adjustment will be made by: multiplying each unit's allocation by 95 percent of such portion of the State's trading program budget; dividing by the total number of NOX allowances allocated under paragraph (b)(1) of this section for the control period; and rounding to the nearest whole number of NOX allowances as appropriate.

(c) For each group of control periods specified in § 97.41(a) through (c), the Administrator will allocate to all NOX Budget units in a given State under § 97.4(a)(2) that commenced operation before May 1, 1997 for allocations under § 97.41(a), May 1, 2003 for allocations under § 97.41(b), and May 1 of the year 5 years before the first year for which the allocation under § 97.41(c) is being calculated, a total number of NOX allowances equal to 95 percent of the portion of the State's trading program budget under § 97.40 covering such units. The Administrator will allocate in accordance with the following procedures:

(1) The Administrator will allocate NOX allowances to each NOX Budget unit under § 97.4(a)(2) for each control period in an amount equaling 0.17 lb/mmBtu multiplied by the heat input determined under paragraph (a) of this section, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate.

(2) If the initial total number of NOX allowances allocated to all NOX Budget units under § 97.4(a)(2) in the State for a control period under paragraph (c)(1) of this section does not equal 95 percent of the portion of the State's trading program budget under § 97.40 covering such units, the Administrator will adjust the total number of NOX allowances allocated to all such NOX Budget units for the control period under paragraph (a)(1) of this section so that the total number of NOX allowances allocated equals 95 percent of the portion of the State's trading program budget under § 97.40 covering such units. This adjustment will be made by: multiplying each unit's allocation by 95 percent of the portion of the State's trading program budget under § 97.40 covering such units; dividing by the total number of NOX allowances allocated under paragraph (c)(1) of this section for the control period; and rounding to the nearest whole number of NOX allowances as appropriate.

(d) For each control period specified in § 97.41(d), the Administrator will allocate NOX allowances to NOX Budget units in a given State under § 97.4(a) (except for units exempt under § 97.4(b)) that commence operation, or are projected to commence operation, on or after: May 1, 1997 (for control periods under § 97.41(a)); May 1, 2003, (for control periods under § 97.41(b)); and May 1 of the year 5 years before the beginning of the group of 5 years that includes the control period (for control periods under § 97.41(c)). The Administrator will make the allocations under this paragraph (d) in accordance with the following procedures:

(1) The Administrator will establish one allocation set-aside for each control period. Each allocation set-aside will be allocated NOX allowances equal to 5 percent of the tons of NOX emission in the State's trading program budget under § 97.40, rounded to the nearest whole number of NOX allowances as appropriate.

(2) The NOX authorized account representative of a NOX Budget unit specified in this paragraph (d) may submit to the Administrator a request, in a format specified by the Administrator, to be allocated NOX allowances for the control period. The NOX allowance allocation request must be received by the Administrator on or after the date on which the State permitting authority issues a permit to construct the unit and by January 1 before the control period for which NOX allowances are requested.

(3) In a NOX allowance allocation request under paragraph (d)(2) of this section, the NOX authorized account representative for a NOX Budget unit under § 97.4(a)(1) may request for the control period NOX allowances in an amount that does not exceed the lesser of:

(i) 0.15 lb/mmBtu multiplied by the unit's maximum design heat input, multiplied by the lesser of 3,672 hours or the number of hours remaining in the control period starting with the day in the control period on which the unit commences operation or is projected to commence operation, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate; or

(ii) The unit's most stringent State or Federal NOX emission limitation multiplied by the unit's maximum design heat input, multiplied by the lesser of 3,672 hours or the number of hours remaining in the control period starting with the day in the control period on which the unit commences operation or is projected to commence operation, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate.

(4) In a NOX allowance allocation request under paragraph (d)(2) of this section, the NOX authorized account representative for a NOX Budget unit under § 97.4(a)(2) may request for a control period NOX allowances in an amount that does not exceed the lesser of:

(i) 0.17 lb/mmBtu multiplied by the unit's maximum design heat input, multiplied by the lesser of 3,672 hours or the number of hours remaining in the control period starting with the day in the control period on which the unit commences operation or is projected to commence operation, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate; or

(ii) The unit's most stringent State or Federal NOX emission limitation multiplied by the unit's maximum design heat input, multiplied by the lesser of 3,672 hours or the number of hours remaining in the control period starting with the day in the control period on which the unit commences operation or is projected to commence operation, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate.

(5) The Administrator will review each NOX allowance allocation request submitted in accordance with paragraph (d)(2) of this section and will allocate NOX allowances pursuant to such request as follows:

(i) Upon receipt of the NOX allowance allocation request, the Administrator will make any necessary adjustments to the request to ensure that the requirements of paragraphs (d) introductory text, (d)(2), (d)(3), and (d)(4) are met.

(ii) The Administrator will determine the following amounts:

(A) The sum of the NOX allowances requested (as adjusted under paragraph (d)(5)(i) of this section) in all NOX allowance allocation requests under paragraph (d)(2) of this section for the control period; and

(B) For units exempt under § 97.4(b) in the State that commenced operation, or are projected to commence operation, on or after May 1, 1997 (for control periods under § 97.41(a)); May 1, 2003, (for control periods under § 97.41(b)); and May 1 of the year 5 years before beginning of the group of 5 years that includes the control period (for control periods under § 97.41(c)), the sum of the NOX emission limitations (in tons of NOX) on which each unit's exemption under § 97.4(b) is based.

(iii) If the number of NOX allowances in the allocation set-aside for the control period less the amount under paragraph (d)(5)(ii)(B) of this section is not less than the amount determined under paragraph (d)(5)(ii)(A) of this section, the Administrator will allocate the amount of the NOX allowances requested (as adjusted under paragraph (d)(5)(i) of this section) to the NOX Budget unit for which the allocation request was submitted.

(iv) If the number of NOX allowances in the allocation set-aside for the control period less the amount under paragraph (d)(5)(ii)(B) of this section is less than the amount determined under paragraph (d)(5)(ii)(A) of this section, the Administrator will allocate, to the NOX Budget unit for which the allocation request was submitted, the amount of NOX allowances requested (as adjusted under paragraph (d)(5)(i) of this section) multiplied by the number of NOX allowances in the allocation set-aside for the control period less the amount determined under paragraph (d)(5)(ii)(B) of this section, divided by the amount determined under paragraph (d)(5)(ii)(A) of this section, and rounded to the nearest whole number of NOX allowances as appropriate.

(e)(1) For a NOX Budget unit that is allocated NOX allowances under paragraph (d) of this section for a control period, the Administrator will deduct NOX allowances under § 97.54(b), (e), or (f) to account for the actual heat input of the unit during the control period. The Administrator will calculate the number of NOX allowances to be deducted to account for the unit's actual heat input using the following formulas and rounding to the nearest whole number of NOX allowance as appropriate, provided that the number of NOX allowances to be deducted shall be zero if the number calculated is less than zero:

(2) The Administrator will transfer any NOX allowances deducted under paragraph (c)(1) of this section to the allocation set-aside for the control period for which they were allocated.

(f) After making the deductions for compliance under § 97.54(b), (e), or (f) for a control period, the Administrator will determine whether any NOX allowances remain in the allocation set-aside for the control period. The Administrator will allocate any such NOX allowances to the NOX Budget units in the State using the following formula and rounding to the nearest whole number of NOX allowances as appropriate:

(g) If the Administrator determines that NOX allowances were allocated under paragraph (b), (c), or (d) of this section for a control period and the recipient of the allocation is not actually a NOX Budget unit under § 97.4(a), the Administrator will notify the NOX authorized account representative and then will act in accordance with the following procedures:

(1)(i) The Administrator will not record such NOX allowances for the control period in an account under § 97.53;

(ii) If the Administrator already recorded such NOX allowances for the control period in an account under § 97.53 and if the Administrator makes such determination before making all deductions pursuant to § 97.54 (except deductions pursuant to § 97.54(d)(2)) for the control period, then the Administrator will deduct from the account NOX allowances equal in number to and allocated for the same or a prior control period as the NOX allowances allocated to such recipient for the control period. The NOX authorized account representative shall ensure that the account contains the NOX allowances necessary for completion of such deduction. If account does not contain the necessary NOX allowances, the Administrator will deduct the required number of NOX allowances, regardless of the control period for which they were allocated, whenever NOX allowances are recorded in the account; or

(iii) If the Administrator already recorded such NOX allowances for the control period in an account under § 97.53 and if the Administrator makes such determination after making all deductions pursuant to § 97.54 (except deductions pursuant to § 97.54(d)(2)) for the control period, then the Administrator will apply paragraph (g)(1)(ii) of this section to any subsequent control period for which NOX allowances were allocated to such recipient.

(2) The Administrator will transfer the NOX allowances that are not recorded, or that are deducted, pursuant to paragraph (g)(1) of this section to an allocation set-aside for the State in which such source is located.

The NOX authorized account representative for each compliance account may identify by serial number the NOX allowances to be deducted from the unit's compliance account under paragraph (b), (d), (e), or (f) of this section. Such identification shall be made in the compliance certification report submitted in accordance with § 97.30.

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

(i) Those NOX allowances that were allocated for the control period to the unit under subpart E or I of this part;

(ii) Those NOX allowances that were allocated for the control period to any unit and transferred and recorded in the account pursuant to subpart G of this part, in order of their date of recordation;

(iii) Those NOX allowances that were allocated for a prior control period to the unit under subpart E or I of this part; and

(iv) Those NOX allowances that were allocated for a prior control period to any unit and transferred and recorded in the account pursuant to subpart G of this part, in order of their date of recordation.

(d) Deductions for excess emissions. (1) After making the deductions for compliance under paragraph (b) of this section, the Administrator will deduct from the unit's compliance account or the overdraft account of the source where the unit is located a number of NOX allowances, allocated for a control period after the control period in which the unit has excess emissions, equal to three times the number of the unit's excess emissions.

(2) If the compliance account or overdraft account does not contain sufficient NOX allowances, the Administrator will deduct the required number of NOX allowances, regardless of the control period for which they were allocated, whenever NOX allowances are recorded in either account.

(3) Any allowance deduction required under paragraph (d) of this section shall not affect the liability of the owners and operators of the NOX Budget unit for any fine, penalty, or assessment, or their obligation to comply with any other remedy, for the same violation, as ordered under the Clean Air Act or applicable State law. The following guidelines will be followed in assessing fines, penalties or other obligations:

(i) For purposes of determining the number of days of violation, if a NOX Budget unit has excess emissions for a control period, each day in the control period (153 days) constitutes a day in violation unless the owners and operators of the unit demonstrate that a lesser number of days should be considered.

(ii) Each ton of excess emissions is a separate violation.

(e) Deductions for units sharing a common stack. In the case of units sharing a common stack and having emissions that are not separately monitored or apportioned in accordance with subpart H of this part:

(1) The NOX authorized account representative of the units may identify the percentage of NOX allowances to be deducted from each such unit's compliance account to cover the unit's share of NOX emissions from the common stack for a control period. Such identification shall be made in the compliance certification report submitted in accordance with § 97.30.

(2) Notwithstanding paragraph (b)(2)(i) of this section, the Administrator will deduct NOX allowances for each such unit until the number of NOX allowances deducted equals the unit's identified percentage under paragraph (e)(1) of this section or, if no percentage is identified, an equal percentage for each unit multiplied by the number of tons of NOX emissions, as determined in accordance with subpart H of this part, from the common stack for the control period for which compliance is being determined. In addition to the deductions under the first sentence of this paragraph (e)(1), the Administrator will deduct NOX allowances for each such unit until the number of NOX allowances deducted equals the number of NOX allowances required to account for actual heat input under § 97.42(e) for the unit for the control period.

(f) Deduction of banked allowances. Each year starting in 2006, after the Administrator has completed the designation of banked NOX allowances under § 97.55(b) and before May 1 of the year, the Administrator will determine the extent to which banked NOX allowances otherwise available under paragraph (a) of this section are available for compliance in the control period for the current year, as follows:

(1) The Administrator will determine the total number of banked NOX allowances held in compliance accounts, overdraft accounts, or general accounts.

(2) If the total number of banked NOX allowances determined, under paragraph (f)(1) of this section, to be held in compliance accounts, overdraft accounts, or general accounts is less than or equal to 10 percent of the sum of the trading program budgets under § 97.40 for all States for the control period, any banked NOX allowance may be deducted for compliance in accordance with paragraphs (a) through (e) of this section.

(3) If the total number of banked NOX allowances determined, under paragraph (f)(1) of this section, to be held in compliance accounts, overdraft accounts, or general accounts exceeds 10 percent of the sum of the trading program budgets under § 97.40 for all States for the control period, any banked allowance may be deducted for compliance in accordance with paragraphs (a) through (e) of this section, except as follows:

(i) The Administrator will determine the following ratio: 0.10 multiplied by the sum of the trading program budgets under § 97.40 for all States for the control period and divided by the total number of banked NOX allowances determined, under paragraph (f)(1) of this section, to be held in compliance accounts, overdraft accounts, or general accounts.

(ii) The Administrator will multiply the number of banked NOX allowances in each compliance account or overdraft account by the ratio determined under paragraph (f)(3)(i) of this section. The resulting product is the number of banked NOX allowances in the account that may be deducted for compliance in accordance with paragraphs (a) through (e) of this section. Any banked NOX allowances in excess of the resulting product may be deducted for compliance in accordance with paragraphs (a) through (e) of this section, except that, if such NOX allowances are used to make a deduction under paragraph (b) or (e) of this section, two (rather than one) such NOX allowances shall authorize up to one ton of NOX emissions during the control period and must be deducted for each deduction of one NOX allowance required under paragraph (b) or (e) of this section.

(g) Recordation of deductions. The Administrator will record in the appropriate compliance account or overdraft account all deductions from such an account pursuant to paragraph (b), (d), (e), or (f) of this section.

NOX allowances may be banked for future use or transfer in a compliance account, an overdraft account, or a general account, as follows:

(a) Any NOX allowance that is held in a compliance account, an overdraft account, or a general account will remain in such account unless and until the NOX allowance is deducted or transferred under § 97.31, § 97.54, § 97.56, or subpart G or I of this part.

(b) The Administrator will designate, as a “banked” NOX allowance, any NOX allowance that remains in a compliance account, an overdraft account, or a general account after the Administrator has made all deductions for a given control period from the compliance account or overdraft account pursuant to § 97.54 (except deductions pursuant to § 97.54(d)(2)) and that was allocated for that control period or a control period in a prior year.

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

(a) The NOX authorized account representative of a general account may instruct the Administrator to close the account by submitting a statement requesting deletion of the account from the NOX Allowance Tracking System and by correctly submitting for recordation under § 97.60 an allowance transfer of all NOX allowances in the account to one or more other NOX Allowance Tracking System accounts.

(b) If a general account shows no activity for a period of a year or more and does not contain any NOX allowances, the Administrator may notify the NOX authorized account representative for the account that the account will be closed and deleted from the NOX Allowance Tracking System 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 NOX allowances into the account under § 97.60 or a statement submitted by the NOX authorized account representative demonstrating to the satisfaction of the Administrator good cause as to why the account should not be closed.

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

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

(b) A specification by serial number of each NOX allowance to be transferred; and

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

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

(1) The transfer is correctly submitted under § 97.60; and

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

(b) A NOX allowance transfer that is submitted for recordation following the NOX allowance transfer deadline and that includes any NOX allowances allocated for a control period in a prior year or the same year as the NOX allowance transfer deadline will not be recorded until after the Administrator completes the recordation of NOX allowance allocations under § 97.53 for the control period in the same year as the NOX allowance transfer deadline.

(c) Where a NOX 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 NOX allowance transfer under § 97.61, the Administrator will notify the NOX authorized account representatives of both the transferor and transferee accounts.

(b) Notification of non-recordation. Within 10 business days of receipt of a NOX allowance transfer that fails to meet the requirements of § 97.61(a), the Administrator will notify the NOX 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 NOX allowance transfer for recordation following notification of non-recordation.

The owners and operators, and to the extent applicable, the NOX authorized account representative of a NOX Budget unit, shall comply with the monitoring, recordkeeping, and reporting requirements as provided in this subpart and in subpart H of part 75 of this chapter.

A provisionally certified monitor may be used under the NOX Budget Trading Program for a period not to exceed 120 days after receipt by the Administrator of the complete certification application for the monitoring system or component thereof under paragraph (b)(3)(ii) of this section. Data measured and recorded by the provisionally certified monitoring system or component thereof, in accordance with the requirements of part 75 of this chapter, will be considered valid quality-assured data (retroactive to the date and time of provisional certification), provided that the Administrator does not invalidate the provisional certification by issuing a notice of disapproval within 120 days of receipt of the complete certification application by the Administrator.

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

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

(B) Incomplete application notice. A certification application will be considered complete when all of the applicable information required to be submitted under paragraph (b)(3)(ii) of this section has been received by the Administrator. If the certification application is not complete, then the Administrator will issue a written notice of incompleteness that sets a reasonable date by which the NOX authorized account representative must submit the additional information required to complete the certification application. If the NOX authorized account representative does not comply with the notice of incompleteness by the specified date, then the Administrator may issue a notice of disapproval under paragraph (b)(3)(iv)(C) of this section. The 120-day review period shall not begin prior to receipt of a complete certification application.

(C) Disapproval notice. If the certification application shows that any monitoring system or component thereof does not meet the performance requirements of this part, or if the certification application is incomplete and the requirement for disapproval under paragraph (b)(3)(iv)(B) of this section has been met, then the Administrator will issue a written notice of disapproval of the certification application. Upon issuance of such notice of disapproval, the provisional certification is invalidated by the Administrator and the data measured and recorded by each uncertified monitoring system or component thereof 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 (b)(3)(v) of this section for each monitoring system or component thereof that is disapproved for initial certification.

(D) Audit decertification. The Administrator may issue a notice of disapproval of the certification status of a monitor in accordance with § 97.72(b).

Data shall be recorded and reported from the earlier of the date and hour corresponding to the date and hour of initial provisional certification under § 97.71(b)(3)(iii) or § 97.71(c) or the first hour of May 1 of the first control period after the unit commences operation.

(3) The NOX authorized account representative shall submit each quarterly report to the Administrator within 30 days following the end of the calendar quarter covered by the report. Quarterly reports shall be submitted in the manner specified in subpart H of part 75 of this chapter and § 75.64 of this chapter.

(i) For units subject to an Acid Rain emissions limitation, quarterly reports shall include all of the data and information required in subpart H of part 75 of this chapter for each NOX Budget unit (or group of units using a common stack) and the data and information required in subpart G of part 75 of this chapter.

(ii) For units not subject to an Acid Rain emissions limitation, quarterly reports are only required to include all of the data and information required in subpart H of part 75 of this chapter for each NOX Budget unit (or group of units using a common stack).

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

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

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

(iii) For a unit that is reporting on a control period basis under paragraph (d)(2)(ii) of this section, the NOX emission rate and NOX concentration values substituted for missing data under subpart D of part 75 of this chapter are calculated using only values from a control period and do not systematically underestimate NOX emissions.

(a) The NOX authorized account representative of a NOX Budget unit may submit a petition under § 75.66 of this chapter to the Administrator requesting approval to apply an alternative to any requirement of this subpart.

(b) Application of an alternative to any requirement of this subpart is in accordance with this subpart only to the extent that the petition is approved by the Administrator under § 75.66 of this chapter.

The owner or operator of a NOX Budget unit that monitors and reports NOX mass emissions using a NOX concentration system and a flow system shall also monitor and report heat input rate at the unit level using the procedures set forth in part 75 of this chapter.

A unit that is in a State (as defined in § 97.2), is not a NOX Budget unit under § 97.4(a), is not a unit exempt under § 97.4(b), vents all of its emissions to a stack, and is operating, may qualify to be a NOX Budget opt-in unit under this subpart. A unit that is a NOX Budget unit under § 97.4(a), is covered by an exemption under § 97.4(b) or § 97.5 that is in effect, or is not operating is not eligible to be a NOX Budget opt-in unit.

Except otherwise as provided in this part, a NOX Budget opt-in unit shall be treated as a NOX Budget unit for purposes of applying subparts A through H of this part.

A unit for which an application for a NOX Budget opt-in permit is submitted, or a NOX Budget opt-in unit, located at the same source as one or more NOX Budget units, shall have the same NOX authorized account representative as such NOX Budget units.

(a) Applying for initial NO X Budget opt-in permit. In order to apply for an initial NOX Budget opt-in permit, the NOX authorized account representative of a unit qualified under § 97.80 may submit to the Administrator and the permitting authority at any time, except as provided under § 97.86(g):

(1) A complete NOX Budget permit application under § 97.22;

(2) A monitoring plan submitted in accordance with subpart H of this part; and

(3) A complete account certificate of representation under § 97.13, if no NOX authorized account representative has been previously designated for the unit.

(b) Duty to reapply. Unless the NOX Budget opt-in permit is terminated or revised under § 97.86(e) or § 97.87(b)(1)(i), the NOX authorized account representative of a NOX Budget opt-in unit shall submit to the Administrator and permitting authority a complete NOX Budget permit application under § 97.22 to renew the NOX Budget opt-in permit in accordance with § 97.21(c) and, if applicable, an updated monitoring plan in accordance with subpart H of this part.

The permitting authority will issue or deny an initial NOX Budget opt-in permit for a unit for which an application for a NOX Budget opt-in permit under § 97.83 is submitted, in accordance with § 97.20 and the following:

(a) Interim review of monitoring plan. The Administrator will determine, on an interim basis, the sufficiency of the monitoring plan accompanying the initial application for a NOX Budget opt-in permit under § 97.83. 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 rate 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 Administrator 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 percent monitor data 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 Administrator will calculate the unit's baseline heat input, which will equal the unit's total heat input (in mmBtu) for the control period, and the unit's baseline NOX emissions rate, which will equal the unit's total NOX mass emissions (in lb) for the control period divided by the unit's baseline heat input.

(d) Issuance of draft NO X Budget opt-in permit for public comment. The permitting authority will issue a draft NOX Budget opt-in permit for public comment in accordance with § 97.20.

(e) Not withstanding paragraphs (a) through (d) of this section, if at any time before issuance of a draft NOX Budget opt-in permit for public comment for the unit, the Administrator or the permitting authority determines that the unit does not qualify as a NOX Budget opt-in unit under § 97.80, the permitting authority will issue a draft denial of a NOX Budget opt-in permit for public comment for the unit in accordance with § 97.20.

(f) Withdrawal of application for NO X Budget opt-in permit. A NOX authorized account representative of a unit may withdraw its application for an initial NOX Budget opt-in permit under § 97.83 at any time prior to the issuance of the initial 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 an initial NOX Budget permit under § 97.83.

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

(a) Each NOX Budget opt-in permit will contain all elements required for a complete NOX Budget opt-in permit application under § 97.22.

(b) Each NOX Budget opt-in permit is deemed to incorporate automatically the definitions of terms under § 97.2 and, upon recordation by the Administrator under subpart F or G of this part, every allocation, transfer, or deduction of NOX allowances to or from the compliance accounts of each NOX Budget opt-in unit covered by the NOX Budget opt-in permit or the overdraft account of the NOX Budget source where the NOX Budget opt-in unit is located.

(a) Requesting withdrawal. To withdraw from the NOX Budget Trading Program, the NOX authorized account representative of a NOX Budget opt-in unit shall submit to the Administrator and 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.

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

(1) For the control period immediately before the withdrawal is to be effective, the NOX authorized account representative must submit or must have submitted to the Administrator and the permitting authority an annual compliance certification report in accordance with § 97.30.

(2) If the NOX Budget opt-in unit has excess emissions for the control period immediately before the withdrawal is to be effective, the Administrator will deduct or has deducted from the NOX Budget opt-in unit's compliance account, or the overdraft account of the NOX Budget source where the NOX Budget opt-in unit is located, the full amount required under § 97.54(d) for the control period.

(3) After the requirements for withdrawal under paragraphs (b)(1) and (2) of this section are met, the Administrator will deduct from the NOX Budget opt-in unit's compliance account, or the overdraft account of the NOX Budget source where the NOX Budget opt-in unit is located, NOX allowances equal in number to and allocated for the same or a prior control period as any NOX allowances allocated to that source under § 97.88 for any control period for which the withdrawal is to be effective. The Administrator will close the NOX Budget opt-in unit's compliance account and transfer any remaining allowances to a general account specified by the owners and operators of the NOX Budget opt-in unit.

(c) A NOX Budget opt-in unit that withdraws from the NOX Budget Trading Program shall comply with all requirements under the NOX Budget Trading Program concerning all years for which such NOX Budget opt-in unit was a NOX Budget opt-in unit, even if such requirements arise or must be complied with after the withdrawal takes effect.

(d) Notification. (1) After the requirements for withdrawal under paragraphs (a) and (b) of this section are met (including deduction of the full amount of NOX allowances required), the Administrator will issue a notification to the permitting authority and the NOX authorized account representative of the NOX Budget opt-in unit of the acceptance of the withdrawal of the NOX Budget opt-in unit as of a specified effective date that is after such requirements have been met and that is prior to May 1 or after September 30.

(2) If the requirements for withdrawal under paragraphs (a) and (b) of this section are not met, the Administrator will issue a notification to the permitting authority and the NOX authorized account representative of the NOX Budget opt-in unit that the request to withdraw is denied. If the NOX Budget opt-in unit's request to withdraw is denied, the NOX Budget opt-in unit shall remain subject to the requirements for a NOX Budget opt-in unit.

(e) Permit revision. After the Administrator issues a notification under paragraph (d)(1) of this section that the requirements for withdrawal have been met, the permitting authority will revise the NOX Budget permit covering the NOX Budget opt-in unit to terminate the NOX Budget opt-in permit as of the effective date specified under paragraph (d)(1) of this section. A NOX Budget opt-in unit shall continue to be a NOX Budget opt-in unit until the effective date of the termination.

(f) Reapplication upon failure to meet conditions of withdrawal. If the Administrator denies the request to withdraw the NOX Budget opt-in unit, the NOX authorized account representative may submit another request to withdraw in accordance with paragraphs (a) and (b) of this section.

(g) Ability to return to the NO X Budget Trading Program. Once a NOX Budget opt-in unit withdraws from the NOX Budget Trading Program and its NOX Budget opt-in permit is terminated under paragraph (e) of this section, the NOX authorized account representative may not submit another application for a NOX Budget opt-in permit under § 97.83 for the unit prior to the date that is 4 years after the date on which the terminated NOX Budget opt-in permit became effective.

(a) Notification. When a NOX Budget opt-in unit becomes a NOX Budget unit under § 97.4(a), the NOX authorized account representative shall notify in writing the permitting authority and the Administrator of such change in the NOX Budget opt-in unit's regulatory status, within 30 days of such change.

(b) Permitting authority's and Administrator's action. (1)(i) When the NOX Budget opt-in unit becomes a NOX Budget unit under § 97.4(a), the permitting authority will revise the NOX Budget opt-in unit's NOX Budget opt-in permit to meet the requirements of a NOX Budget permit under § 97.23 as of an effective date that is the date on which such NOX Budget opt-in unit becomes a NOX Budget unit under § 97.4(a).

(ii)(A) The Administrator will deduct from the compliance account for the NOX Budget unit under paragraph (b)(1)(i) of this section, or the overdraft account of the NOX Budget source where the unit is located, NOX allowances equal in number to and allocated for the same or a prior control period as:

(1) Any NOX allowances allocated to the NOX Budget unit (as a NOX Budget opt-in unit) under § 97.88 for any control period after the last control period during which the unit's NOX Budget opt-in permit was effective; and

(2) If the effective date of the NOX Budget permit revision under paragraph (b)(1)(i) of this section is during a control period, the NOX allowances allocated to the NOX Budget unit (as a NOX Budget opt-in unit) under § 97.88 for the control period multiplied by the number of days in the control period starting with the effective date of the permit revision under paragraph (b)(1)(i) of this section, divided by the total number of days in the control period, and rounded to the nearest whole number of NOX allowances as appropriate.

(B) The NOX authorized account representative shall ensure that the compliance account of the NOX Budget unit under paragraph (b)(1)(i) of this section, or the overdraft account of the NOX Budget source where the unit is located, contains the NOX allowances necessary for completion of the deduction under paragraph (b)(1)(ii)(A) of this section. If the compliance account or overdraft account does not contain the necessary NOX allowances, the Administrator will deduct the required number of NOX allowances, regardless of the control period for which they were allocated, whenever NOX allowances are recorded in either account.

(iii)(A) For every control period during which the NOX Budget permit revised under paragraph (b)(1)(i) of this section is in effect, the NOX Budget unit under paragraph (b)(1)(i) of this section will be treated, solely for purposes of NOX allowance allocations under § 97.42, as a unit that commenced operation on the effective date of the NOX Budget permit revision under paragraph (b)(1)(i) of this section and will be allocated NOX allowances under § 97.42. The unit's deadline under § 97.84(b) for meeting monitoring requirements in accordance with subpart H of this part shall not changed by the change in the unit's regulatory status or by the revision of the NOX Budget permit under paragraph (b)(1)(i) of this section.

(B) Notwithstanding paragraph (b)(1)(iii)(A) of this section, if the effective date of the NOX Budget permit revision under paragraph (b)(1)(i) of this section is during a control period, the following number of NOX allowances will be allocated to the NOX Budget unit under paragraph (b)(1)(i) of this section under § 97.42 for the control period: the number of NOX allowances otherwise allocated to the NOX Budget unit under § 97.42 for the control period multiplied by the number of days in the control period starting with the effective date of the permit revision under paragraph (b)(1)(i) of this section, divided by the total number of days in the control period, and rounded to the nearest whole number of NOX allowances as appropriate.

(2)(i) When the NOX authorized account representative of a NOX Budget opt-in unit does not renew its NOX Budget opt-in permit under § 97.83(b), the Administrator will deduct from the NOX Budget opt-in unit's compliance account, or the overdraft account of the NOX Budget source where the NOX Budget opt-in unit is located, NOX allowances equal in number to and allocated for the same or a prior control period as any NOX allowances allocated to the NOX Budget opt-in unit under § 97.88 for any control period after the last control period for which the NOX Budget opt-in permit is effective. The NOX authorized account representative shall ensure that the NOX Budget opt-in unit's compliance account or the overdraft account of the NOX Budget source where the NOX Budget opt-in unit is located contains the NOX allowances necessary for completion of such deduction. If the compliance account or overdraft account does not contain the necessary NOX allowances, the Administrator will deduct the required number of NOX allowances, regardless of the control period for which they were allocated, whenever NOX allowances are recorded in either account.

(ii) After the deduction under paragraph (b)(2)(i) of this section is completed, the Administrator will close the NOX Budget opt-in unit's compliance account. If any NOX allowances remain in the compliance account after completion of such deduction and any deduction under § 97.54, the Administrator will close the NOX Budget opt-in unit's compliance account and transfer any remaining allowances to a general account specified by the owners and operators of the NOX Budget opt-in unit.

(a) NO X allotment allocation. (1) By April 1 immediately before the first control period for which the NOX Budget opt-in permit is effective, the Administrator will determine by order the NOX allowance allocations for the NOX Budget opt-in unit for the control period in accordance with paragraph (b) of this section.

(2) By no later than April 1, after the first control period for which the NOX Budget opt-in permit is in effect, and April 1 of each year thereafter, the Administrator will determine by order the NOX allowance allocations for the NOX Budget opt-in unit for the next control period, in accordance with paragraph (b) of this section.

(3) The Administrator will make available to the public each determination of NOX allowance allocations under paragraph (a)(1) or (2) of this section and will provide an opportunity for submission of objections to the determination. Objections shall be limited to addressing whether the determination is in accordance with paragraph (b) of this section. Based on any such objections, the Administrator will adjust each determination to the extent necessary to ensure that it is in accordance with paragraph (b) of this section.

(b) For each control period for which the NOX Budget opt-in unit has an approved NOX Budget opt-in permit, the NOX Budget opt-in unit will be allocated NOX allowances in accordance with the following procedures:

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

(i) The unit's baseline heat input determined pursuant to § 97.84(c); or

(ii) The unit's heat input, as determined in accordance with subpart H of this part, for the control period in the year prior to the year of the control period for which the NOX allocations are being calculated.

(2) The Administrator will allocate NOX allowances to the unit in an amount equaling the heat input determined under paragraph (b)(1) of this section multiplied by the lesser of the unit's baseline NOX emissions rate determined under § 97.84(c) or the most stringent State or federal NOX emissions limitation applicable to the unit during the control period, divided by 2,000 lb/ton, and rounded to the nearest whole number of NOX allowances as appropriate.
