Sec. 5.

(a) For each control period in 2021 and thereafter, the department shall allocate to all existing units that have a baseline heat input the total amount of allowances as listed in section 2(c) of this rule in accordance with this section.

(b) The initial allocation for an existing unit is the existing unit budget multiplied by the ratio of the baseline heat input of the unit to the total amount of baseline heat inputs of all CSAPR NO_x annual units, rounded to the nearest whole allowance.

(c) A unit receives no allowances if the unit does not operate during the control period in two (2) consecutive years as follows:

(1) Allowances must not be allocated to the unit for the control period in the fifth year after the first year of not operating and in each year after the fifth year.

(2) If the unit resumes operation, the department must allocate allowances to the unit in accordance with the standards for new unit allocations until the unit has a baseline heat input.

(d) The allocation to each unit is the lesser of the following, plus any reapportioned allowances:

(1) Initial allocation under subsection (b).

(2) A cap on emissions pursuant to a federally enforceable judicial consent decree.

(3) Maximum historic emissions, as determined under section 4(c) of this rule.

(4) No allowances if the unit does not operate as described in subsection (c).

(e) All allowances remaining after the application of subsections (b) and (c) are reapportioned as follows, until the entire existing unit budget is allocated, with each resulting allocation value rounded to the nearest whole allowance:

(1) Remaining allowances are reapportioned to the remaining units whose initial allocation is not limited by subsection (d)(2) through (d)(4).

(2) Allocations are apportioned on the same basis as under subsection (b).

(3) These steps are repeated with each revised allocation distribution until the entire existing unit budget is allocated.

(f) By March 1 of each year existing unit allocations are made under this section, the department shall make the allowance allocations available for public review. The department may adjust each determination if appropriate or necessary to ensure that it is in accordance with this rule.
