††††† (a) Multiplying 0.15 lb/MMBTU or the permit limit, whichever is less, by the heat input determined under Section 4(4) of this administrative regulation, rounded to the nearest whole NOx allowance as appropriate.

††††† (b) If the initial total number of NOx allowances allocated for an allocation period to all NOx budget units in Kentucky included in the pools specified in subsection (2)(a)1 and 3 of this section does not equal ninety-five (95) percent for the 2004 to 2006 allocation period, or ninety-eight (98) percent for each allocation period thereafter, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to existing electric generating units, the cabinet shall:

††††† 1. Adjust the total number of NOx allowances allocated to all electric generating units in the applicable pool so that the total number of NOx allowances allocated equals ninety-five (95) percent for the 2004 to 2006 allocation period, or ninety-eight (98) percent for each allocation period thereafter, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to electric generating units; and

††††† 2. Make this adjustment by multiplying each unit's allocation by ninety-five (95) percent for the 2004 to 2006 allocation period, or ninety-eight (98) percent thereafter, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to electric generating units divided by the total number of NOx allowances allocated under paragraph (a) of this subsection, and rounding to the nearest whole NOx allowance as appropriate.

††††† (6) For industrial boilers or turbines included in the pool specified in subsection (2)(b)1 of this section, the cabinet shall allocate NOx allowances to each NOx budget unit in an amount equal to the result obtained by:

††††† (a) Multiplying 0.17 lb/MMBTU or the permit limit, whichever is less, by the heat input determined under subsection (4) of this section, rounded to the nearest whole NOx allowance as appropriate.

††††† (b) If the initial total number of NOx allowances allocated for an allocation period to all NOx budget units in Kentucky included in the pool specified in subsection (2)(b)1 of this section does not equal ninety-eight (98) percent for each allocation period, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to existing industrial boilers or turbines, the cabinet shall:

††††† 1. Adjust the total number of NOx allowances allocated to all industrial boilers or turbines in the applicable pool so that the total number of NOx allowances allocated equals ninety-eight (98) percent for each allocation period, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to industrial boilers or turbines; and

††††† 2. Make this adjustment by multiplying each unit's allocation by ninety-eight (98) percent, of the number of tons of NOx emissions in Kentucky's trading program budget apportioned to industrial boilers or turbines divided by the total number of NOx allowances allocated under paragraph (a) of this subsection, and rounding to the nearest whole NOx allowance as appropriate.

††††† (7)(a) The Commonwealth of Kentucky shall establish an account pursuant to 401 KAR 51:190 for the purpose of selling the NOx allowances in the pools specified in subsection (2)(a)2 and 4 of this section. The proceeds from the sale of the NOx allowances shall be deposited in the general fund of the Commonwealth of Kentucky.

††††† (b) For NOx budget units included in the pool specified in subsection (2)(b)2 of this section, the cabinet shall allocate NOx allowances to each unit according to the following procedures:

††††† 1. The cabinet shall establish one (1) allocation set-aside for each control period. Each allocation set-aside shall be allocated NOx allowances equal to two (2) percent for each control period of the tons of NOx emissions in Kentucky's trading program budget, rounded to the nearest whole NOx allowance as appropriate.

††††† 2. The NOx authorized account representative may submit to the cabinet a request, in writing, to be allocated NOx allowances starting with the control period during which the NOx budget unit commences commercial operation, or is projected to commence commercial operation, and ending with the control period preceding the control period for which it will receive an allocation under subsection (2)(b)1 of this section. The request shall be in accordance with the following requirements:

††††† a. The NOx allowance allocation request shall be submitted prior to May 1 of the first control period for which the NOx allowance allocation is requested and after the date on which the cabinet issues a permit to construct to the NOx budget unit; and

††††† b. For a control period, the NOx authorized account representative may request NOx allowances in an amount that does not exceed 0.17 lb/MMBTU or the permitted limit, whichever is less, multiplied by the NOx budget unit's maximum design heat input in MMBTU/hr multiplied by the number of hours remaining in the control period starting with the first day in the control period on which the unit operated or is projected to operate.

††††† 3. The cabinet shall review, and allocate NOx allowances pursuant to, each NOx allowance allocation request in the order that the requests are received by the cabinet as of the close of business each day, with each consecutive day determining the order:

††††† a. Upon receipt of the NOx allowance allocation request, the cabinet shall determine whether, and shall make any necessary adjustments to the request to ensure that the control period and the number of NOx allowances specified are consistent with the requirements of this subsection.

††††† b. If the allocation set-aside for the control period for which NOx allowances are requested:

††††† (i) Has an amount of NOx allowances not less than the number requested, as adjusted by the cabinet, the cabinet shall allocate the amount of the NOx allowances requested, as adjusted by the cabinet, to the NOx budget unit.

††††† (ii) Has a smaller amount of NOx allowances than the number requested, as adjusted by the cabinet, the cabinet will deny in part the request and allocate only the remaining number of NOx allowances in the allocation set-aside to the NOx budget unit.

††††† (iii) Once an allocation set-aside for a control period has been depleted of all NOx allowances, the cabinet shall deny, and shall not allocate any NOx allowances pursuant to a NOx allowance allocation request under which NOx allowances have not already been allocated for the control period.

††††† 4. Within sixty (60) days of receipt of a NOx allowance allocation request, the cabinet shall take appropriate action under this subsection and shall notify the U.S. EPA of the number of NOx allowances allocated for the control period to the NOx budget unit.

††††† 5. For a NOx budget unit that is allocated NOx allowances under this subparagraph, the U.S. EPA shall deduct NOx allowances to account for the actual utilization of the unit during the control period, and for any NOx allowances returned to Kentucky, the cabinet shall allocate to the NOx budget units in Kentucky using the following formula and rounding to the nearest whole NOx allowance as appropriate:

††††† a. Unit's share of NOx allowances remaining in allocation set-aside equals total NOx allowances remaining in allocation set-aside multiplied by the quantity generated by dividing the unit's NOx allowance allocation by Kentucky's trading program budget excluding allocation set-aside;

††††† b. If:

††††† (i) Total NOx allowances remaining in allocation set-aside is the total number of NOx allowances remaining in the allocation set-aside for the control period to which the allocation set-aside applies;

††††† (ii) Unit's NOx allowance allocation is the number of NOx allowances allocated under subsection (2)(b)2 of this section to the unit for the control period to which the allocation set-aside applies; and

††††† (iii) State trading program budget excluding allocation set-aside is Kentucky's trading program budget for the control period to which the allocation set-aside applies multiplied by ninety-five (95) percent if the control period is in 2004, 2005, or 2006 or ninety-eight (98) percent if the control period is in any year thereafter, rounded to the nearest whole NOx allowance as appropriate.

††††† (8) NOx allowances created pursuant to 401 KAR 51:180 for early reduction credits or emergency compliance shall not be included in the allocation or sale of the pools specified in this section.

 

††††† Section 5. Allocation of NOx Allowances. (1) The cabinet shall determine the number of NOx allowances to be allocated to eligible NOx budget units for the allocation period beginning in 2004 and in each subsequent allocation period using the method described in Section 4 of this administrative regulation.

††††† (2) A NOx budget unit that commences commercial operation on or before May 1 of the year that is three (3) years before the first year of the applicable allocation period shall be included in the applicable allocation pool as specified in Section 4(2)(a)1, 3, or (b)1 of this administrative regulation.

††††† (3) If the U.S. EPA changes the number of NOx allowances assigned to Kentucky before the end of an allocation period, the cabinet shall reallocate the NOx allowances prior to the beginning of the next control period in the same ratio as the original allocation for that period.

††††† (4) The cabinet shall notify the U.S. EPA and NOx budget sources of the NOx allowances to be allocated and sold by the Commonwealth of Kentucky pursuant to this section and Section 4 of this administrative regulation:

††††† (a) For units that commence commercial operation on or before May 1 of the year that is three (3) years before the first year of the applicable allocation period:

††††† 1. Not later than sixty (60) days after the effective date of this administrative regulation for the allocation period beginning in 2004; and

††††† 2. By April 1 of the year that is three (3) years prior to the next allocation period; and
