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

(i) The CAIR NOX opt-in unit's baseline NOX emissions rate (in lb/mmBtu) determined under §96.184(d) and multiplied by 70 percent; or

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

(3) The permitting authority will allocate CAIR NOX allowances to the CAIR NOX opt-in unit in an amount equaling the heat input under paragraph (b)(1) of this section, multiplied by the NOX emission rate under paragraph (b)(2) of this section, divided by 2,000 lb/ton, and rounded to the nearest whole allowance as appropriate.

(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 §96.183(a)(5)) providing for, allocation to a CAIR NOX opt-in unit of CAIR NOX allowances under this paragraph (subject to the conditions in §§96.184(h) and 96.186(g)), the permitting authority will allocate to the CAIR NOX opt-in unit as follows:

(1) For each control period in 2009 through 2014 for which the CAIR NOX opt-in unit is to be allocated CAIR NOX allowances,

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

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

(A) The CAIR NOX opt-in unit's baseline NOX emissions rate (in lb/mmBtu) determined under §96.184(d); or

(B) The most stringent State or Federal NOX emissions limitation applicable to the CAIR NOX opt-in unit at any time during the control period in which the CAIR NOX opt-in unit enters the CAIR NOX Annual Trading Program under §96.184(g).

(iii) The permitting authority will allocate CAIR NOX allowances to the CAIR NOX opt-in unit in an amount equaling the heat input under paragraph (c)(1)(i) of this section, multiplied by the NOX emission rate under paragraph (c)(1)(ii) of this section, divided by 2,000 lb/ton, and rounded to the nearest whole allowance as appropriate.

(2) For each control period in 2015 and thereafter for which the CAIR NOX opt-in unit is to be allocated CAIR NOX allowances,

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

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

(A) 0.15 lb/mmBtu;

(B) The CAIR NOX opt-in unit's baseline NOX emissions rate (in lb/mmBtu) determined under §96.184(d); or

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

(iii) The permitting authority will allocate CAIR NOX allowances to the CAIR NOX opt-in unit in an amount equaling the heat input under paragraph (c)(2)(i) of this section, multiplied by the NOX emission rate under paragraph (c)(2)(ii) of this section, divided by 2,000 lb/ton, and rounded to the nearest whole allowance as appropriate.

(d) Recordation.

(1) The Administrator will record, in the compliance account of the source that includes the CAIR NOX opt-in unit, the CAIR NOX allowances allocated by the permitting authority to the CAIR NOX opt-in unit under paragraph (a)(1) of this section.

(2) By December 1 of the control period in which a CAIR NOX opt-in unit enters the CAIR NOX Annual Trading Program under §96.184(g) and December 1 of each year thereafter, the Administrator will record, in the compliance account of the source that includes the CAIR NOX opt-in unit, the CAIR NOX allowances allocated by the permitting authority to the CAIR NOX opt-in unit under paragraph (a)(2) of this section.
