§ 97.42 NOX allowance allocations.
(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.
