Section 97.612 - CSAPR SO[2] Group 1 allowance allocations to new units(a)Allocations from new unit set-asides. For each control period in 2015 and thereafter and for the CSAPR SO2 Group 1 units in each State and areas of Indian country within the borders of the State subject to the State's SIP authority, the Administrator will allocate CSAPR SO2 Group 1 allowances to the CSAPR SO2 Group 1 units as follows: (1) The CSAPR SO2 Group 1 allowances will be allocated to the following CSAPR SO2 Group 1 units, except as provided in paragraph (a)(10) of this section:(i) CSAPR SO2 Group 1 units that are not allocated an amount of CSAPR SO2 Group 1 allowances in the notice of data availability issued under § 97.611(a)(1) and that have deadlines for certification of monitoring systems under § 97.630(b) not later than December 31 of the year of the control period;(ii) CSAPR SO2 Group 1 units whose allocation of an amount of CSAPR SO2 Group 1 allowances for such control period in the notice of data availability issued under § 97.611(a)(1) is covered by § 97.611(c)(2) or (3) ;(iii) CSAPR SO2 Group 1 units that are allocated an amount of CSAPR SO2 Group 1 allowances for such control period in the notice of data availability issued under § 97.611(a)(1) , which allocation is terminated for such control period pursuant to § 97.611(a)(2) , and that operate during the control period immediately preceding such control period, for allocations for a control period before 2021, or that operate during such control period, for allocations for a control period in 2021 or thereafter; or(iv) For purposes of paragraph (a)(9) of this section, CSAPR SO2 Group 1 units under § 97.611(c)(1)(ii) whose allocation of an amount of CSAPR SO2 Group 1 allowances for such control period in the notice of data availability issued under § 97.611(b)(1)(ii)(B) is covered by § 97.611(c)(2) or (3) .(2) The Administrator will establish a separate new unit set-aside for the State for each such control period. Each such new unit set-aside will be allocated CSAPR SO2 Group 1 allowances in an amount equal to the applicable amount of tons of SO2 emissions as set forth in § 97.610(a) and will be allocated additional CSAPR SO2 Group 1 allowances (if any) in accordance with § 97.611(a)(2) and (c)(5) and paragraph (b)(10) of this section.(3) The Administrator will determine, for each CSAPR SO2 Group 1 unit described in paragraph (a)(1) of this section, an allocation of CSAPR SO2 Group 1 allowances for the latest of the following control periods and for each subsequent control period: (i) The control period in 2015;(ii)(A) The first control period after the control period in which the CSAPR SO2 Group 1 unit commences commercial operation, for allocations for a control period before 2021; or(B) The control period containing the deadline for certification of the CSAPR SO2 Group 1 unit's monitoring systems under § 97.630(b) , for allocations for a control period in 2021 or thereafter;(iii) For a unit described in paragraph (a)(1)(ii) of this section, the first control period in which the CSAPR SO2 Group 1 unit operates in the State and areas of Indian country within the borders of the State subject to the State's SIP authority after operating in another jurisdiction and for which the unit is not already allocated one or more CSAPR SO2 Group 1 allowances; and(iv) For a unit described in paragraph (a)(1)(iii) of this section, the first control period after the control period in which the unit resumes operation, for allocations for a control period before 2021, or the control period in which the unit resumes operation, for allocations for a control period in 2021 or thereafter.(4)(i) The allocation to each CSAPR SO2 Group 1 unit described in paragraphs (a)(1)(i) through (iii) of this section and for each control period described in paragraph (a)(3) of this section will be an amount equal to the unit's total tons of SO2 emissions during the immediately preceding control period, for allocations for a control period before 2021, or the unit's total tons of SO2 emissions during the control period, for allocations for a control period in 2021 or thereafter.(ii) The Administrator will adjust the allocation amount in paragraph (a)(4)(i) of this section in accordance with paragraphs (a)(5) through (7) and (12) of this section.(5) The Administrator will calculate the sum of the allocation amounts of CSAPR SO2 Group 1 allowances determined for all such CSAPR SO2 Group 1 units under paragraph (a)(4)(i) of this section in the State and areas of Indian country within the borders of the State subject to the State's SIP authority for such control period.(6) If the amount of CSAPR SO2 Group 1 allowances in the new unit set-aside for the State for such control period is greater than or equal to the sum under paragraph (a)(5) of this section, then the Administrator will allocate the amount of CSAPR SO2 Group 1 allowances determined for each such CSAPR SO2 Group 1 unit under paragraph (a)(4)(i) of this section.(7) If the amount of CSAPR SO2 Group 1 allowances in the new unit set-aside for the State for such control period is less than the sum under paragraph (a)(5) of this section, then the Administrator will allocate to each such CSAPR SO2 Group 1 unit the amount of the CSAPR SO2 Group 1 allowances determined under paragraph (a)(4)(i) of this section for the unit, multiplied by the amount of CSAPR SO2 Group 1 allowances in the new unit set-aside for such control period, divided by the sum under paragraph (a)(5) of this section, and rounded to the nearest allowance.(8) For a control period before 2021, the Administrator will notify the public, through the promulgation of the notices of data availability described in § 97.611(b)(1)(i) and (ii) , of the amount of CSAPR SO2 Group 1 allowances allocated under paragraphs (a)(2) through (7) and (12) of this section for such control period to each CSAPR SO2 Group 1 unit eligible for such allocation.(9) For a control period before 2021, if, after completion of the procedures under paragraphs (a)(5) through (8) of this section for such control period, any unallocated CSAPR SO2 Group 1 allowances remain in the new unit set-aside for the State for such control period, the Administrator will allocate such CSAPR SO2 Group 1 allowances as follows- (i) The Administrator will determine, for each unit described in paragraph (a)(1) of this section that commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending November 30 of the year of such control period, the positive difference (if any) between the unit's emissions during such control period and the amount of CSAPR SO2 Group 1 allowances referenced in the notice of data availability required under § 97.611(b)(1)(ii) for the unit for such control period;(ii) The Administrator will determine the sum of the positive differences determined under paragraph (a)(9)(i) of this section;(iii) If the amount of unallocated CSAPR SO2 Group 1 allowances remaining in the new unit set-aside for the State for such control period is greater than or equal to the sum determined under paragraph (a)(9)(ii) of this section, then the Administrator will allocate the amount of CSAPR SO2 Group 1 allowances determined for each such CSAPR SO2 Group 1 unit under paragraph (a)(9)(i) of this section; and(iv) If the amount of unallocated CSAPR SO2 Group 1 allowances remaining in the new unit set-aside for the State for such control period is less than the sum under paragraph (a)(9)(ii) of this section, then the Administrator will allocate to each such CSAPR SO2 Group 1 unit the amount of the CSAPR SO2 Group 1 allowances determined under paragraph (a)(9)(i) of this section for the unit, multiplied by the amount of unallocated CSAPR SO2 Group 1 allowances remaining in the new unit set-aside for such control period, divided by the sum under paragraph (a)(9)(ii) of this section, and rounded to the nearest allowance.(10) If, after completion of the procedures under paragraphs (a)(9) and (12) of this section for a control period before 2021, or under paragraphs (a)(2) through (7) and (12) of this section for a control period in 2021 or thereafter, any unallocated CSAPR SO2 Group 1 allowances remain in the new unit set-aside for the State for such control period, the Administrator will allocate to each CSAPR SO2 Group 1 unit that is in the State and areas of Indian country within the borders of the State subject to the State's SIP authority, is allocated an amount of CSAPR SO2 Group 1 allowances in the notice of data availability issued under § 97.611(a)(1) , and continues to be allocated CSAPR SO2 Group 1 allowances for such control period in accordance with § 97.611(a)(2) , an amount of CSAPR SO2 Group 1 allowances equal to the following: The total amount of such remaining unallocated CSAPR SO2 Group 1 allowances in such new unit set-aside, multiplied by the unit's allocation under § 97.611(a) for such control period, divided by the remainder of the amount of tons in the applicable State SO2 Group 1 trading budget minus the sum of the amounts of tons in such new unit set-aside and the Indian country new unit set-aside for the State for such control period, and rounded to the nearest allowance.(11)(i) For a control period before 2021, the Administrator will notify the public, through the promulgation of the notices of data availability described in § 97.611(b)(1)(iii), (iv), and (v) , of the amount of CSAPR SO2 Group 1 allowances allocated under paragraphs (a)(9), (10), and (12) of this section for such control period to each CSAPR SO2 Group 1 unit eligible for such allocation.(ii) For a control period in 2021 or thereafter, the Administrator will notify the public, through the promulgation of the notices of data availability described in § 97.611(b)(1)(i), (ii), and (v) , of the amount of CSAPR SO2 Group 1 allowances allocated under paragraphs (a)(2) through (7), (10), and (12) of this section for such control period to each CSAPR SO2 Group 1 unit eligible for such allocation.(12) Notwithstanding the requirements of paragraphs (a)(2) through (11) of this section, if the calculations of allocations from a new unit set-aside for a control period before 2021 under paragraph (a)(7) of this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a control period in 2021 or thereafter under paragraph (a)(7) of this section or paragraphs (a)(6) and (10) of this section, would otherwise result in total allocations from such new unit set-aside unequal to the total amount of such new unit set-aside, then the Administrator will adjust the results of such calculations as follows. The Administrator will list the CSAPR SO2 Group 1 units in descending order based on such units' allocation amounts under paragraph (a)(7), (a)(9)(iv), or (a)(10) of this section, as applicable, and, in cases of equal allocation amounts, in alphabetical order of the relevant sources' names and numerical order of the relevant units' identification numbers, and will adjust each unit's allocation amount under such paragraph upward or downward by one CSAPR SO2 Group 1 allowance (but not below zero) in the order in which the units are listed, and will repeat this adjustment process as necessary, until the total allocations from such new unit set-aside equal the total amount of such new unit set-aside.(b)Allocations from Indian country new unit set-asides.
