Ind. Admin. Code tit. 326, r. 24-5-7 – Unallocated new unit set-aside allowances

Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11

Sec. 7. (a) Unallocated allowances remaining in the new unit set-aside after completion of the procedures of section 6 of this rule, for a control period, shall be allocated first to new units as follows:

(1) For each unit that commenced commercial operation during the period starting January 1 of the year before the year of the control period and ending November 30 of the year of the control period, the department shall determine the positive difference, if any, between the unit's emissions during the control period and the amount of allowances awarded for the unit for the control period.

(2) The department shall determine the sum of the positive differences determined under subdivision (1) and then proceed as follows:

(A) If the amount of unallocated allowances remaining in the new unit set-aside for a control period is greater than or equal to the sum determined under this subdivision, then the department must allocate the amount of allowances determined for each unit under subdivision (1).

(B) If the amount of unallocated allowances remaining in the new unit set-aside for a control period is less than the sum under this subdivision, then the department must allocate to each unit under the following formula, rounded to the nearest whole allowance:

Unit allowance = ((E-A) x RNUSA) / Sum

Where:		Unit allowance is the total allowances allocated to the unit.
		E is the unit's emissions during the control period.
		A is the amount of allowances awarded for the unit for the control period.
		RNUSA is the remaining allowances in the new unit set-aside.
		Sum is the total amount of allocations under this subdivision.

(b) After completion of the procedures under subsection (a) for a control period, if any unallocated allowances remain in the new unit set- aside for the control period, the department shall allocate to each existing unit that was allocated allowances under section 5 of this rule, an amount of allowances under the following formula:

Unit allowance = (UA × EUA) / EUB

Where:		Unit allowance is the total allowances allocated to the unit.
		UA is the total amount of the remaining unallocated allowances in the new unit set-aside.
		EUA is the unit's allocation under section 5 of this rule for the control period.
		EUB is the existing unit budget, as listed in section 2(c) of this rule, for the control period, rounded to the nearest whole allowance.

(c) The department shall notify each CSAPR designated representative of the amount of allowances allocated under this section.
