§97.88. NO X allowance allocations to opt-in units. — Inbound Citations

(xiii) The decision on the allocation of NOX allowances to a NOX Budget opt-in unit under § 97.88 of this chapter.

(3) A nitrogen oxides emission rate (or NOX-diluent) monitoring system, consisting of a NOX pollutant concentration monitor, a diluent gas (CO2 or O2) monitor, and an automated DAHS. A NOX concentration monitoring system provides a permanent, continuous record of: NOX concentration in units of parts per million (ppm), diluent gas concentration in units of percent O2 or CO2 (percent O2 or CO2), and NOX emission rate in units of pounds per million British thermal units (lb/mmBtu); and

(a) Consistent with § 97.51(a), the Administrator will establish one compliance account for each NOX Budget unit and one overdraft account for each source with two or more NOX Budget units. Allocations of NOX allowances pursuant to subpart E of this part or § 97.88, and deductions or transfers of NOX allowances pursuant to § 97.31, § 96.54, § 96.56, subpart G of this part, or subpart I of this part will be recorded in compliance accounts or overdraft accounts in accordance with this subpart.

(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.

(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.

(a) The Administrator will record the NOX allowances for 2004 for a NOX Budget unit allocated under subpart E of this part in the unit's compliance account, except for NOX allowances under § 97.4(b)(4)(ii) or § 97.5(c)(2), which will be recorded in the general account specified by the owners and operators of the unit. The Administrator will record NOX allowances for 2004 for a NOX Budget opt-in unit in the unit's compliance account as allocated under § 97.88(a).
