NR 409.065(7)(d)1.a.a. For each unit, the unit’s actual annual average emission rate for the calendar year, in pounds per million Btu, is less than or equal to its alternative contemporaneous annual emission limitation in the averaging plan.
NR 409.065(7)(d)1.b.b. For each unit with an alternative contemporaneous emission limitation less stringent than the applicable emission limitation in sub. (2), (3) or (4), the actual annual heat input for the calendar year does not exceed the annual heat input limit in the averaging plan.
NR 409.065(7)(d)1.c.c. For each unit with an alternative contemporaneous annual emission limitation more stringent than the applicable emission limitation in sub. (2), (3) or (4), the actual annual heat input for the calendar year is not less than the annual heat input limit in the averaging plan.
NR 409.065(7)(d)2.2. ‘Group showing of compliance.’ If one or more of the units does not meet the requirements under subd. 1., the designated representative shall demonstrate, in accordance with subd. 2. a. (i.e., Equation 2) that the actual Btu-weighted annual average emission rate for the units in the plan is less than or equal to the Btu-weighted annual average rate for the same units had they each been operated, during the same period of time, in compliance with the applicable emission limitations in sub. (2), (3) or (4).
NR 409.065(7)(d)2.a.a. A group showing of compliance shall be made based on the following equation:
(Equation 2)
where:
Rai is the actual annual average emission rate for unit i, in pounds per million Btu, as determined using the procedures in 40 CFR part 75. For units in an averaging plan utilizing a common stack pursuant to 40 CFR 75.17(a)(2)(i)(B), use the same NOx emission rate value for each unit utilizing the common stack, and calculate this value in accordance with appendix F of 40 CFR part 75.
Rli is the applicable annual emission limitation for unit i, in pounds per million Btu, as specified in sub. (2), (3) or (4), except that for early election units, which may be included in an averaging plan only on or after January 1, 2000, Rli shall equal the most stringent applicable emission limitation under sub. (2) or (4); for units with an alternative emission limitation, Rli shall equal the applicable emission limitation under sub. (2), (3) or (4), not the alternative emission limitation
HIai is the actual annual heat input for unit i, in million Btu, as determined using the procedures in 40 CFR part 75
n is the number of units in the averaging plan
NR 409.065(7)(d)2.b.b. If there is a successful group showing of compliance under subd. 2. a. for a calendar year, then all units in the averaging plan shall be deemed to be in compliance for that year with their alternative contemporaneous emission limitations and annual heat input limits under subd. 1.
NR 409.065(7)(d)3.3. ‘Liability.’ The owners and operators of a unit governed by an approved averaging plan shall be liable for any violation of the plan or this section at that unit or any other unit in the plan, including liability for fulfilling the obligations specified in 40 CFR part 77 and sections 113 and 411 of the act.
NR 409.065(7)(d)4.4. ‘Withdrawal or termination.’ The designated representative may submit a notification to terminate an approved averaging plan in accordance with s. NR 409.09 (1) (d), no later than October 1 of the calendar year for which the plan is to be withdrawn or terminated.
NR 409.065(8)(8)Compliance and excess emissions. Excess emissions of nitrogen oxides under 40 CFR 77.6 shall be calculated as follows:
NR 409.065(8)(a)(a) For a unit that is not in an approved averaging plan:
NR 409.065(8)(a)1.1. Calculate EEi for each portion of the calendar year that the unit is subject to a different NOx emission limitation:
(Equation 3)
where:
EEi is the excess emissions for NOx for the portion of the calendar year (in tons)
Rai is the actual average emission rate for the unit (in pounds per million Btu), determined according to 40 CFR part 75 for the portion of the calendar year for which the applicable emission limitation Rli is in effect
Rli is the applicable emission limitation for the unit (in pounds per million Btu), as specified in sub. (2), (3) or (4) or as determined under sub. (6)
HIi is the actual heat input for the unit, (in million Btu), determined according to 40 CFR part 75 for the portion of the calendar year for which the applicable emission limitation, Rli, is in effect
NR 409.065(8)(a)2.2. If EEi is a negative number for any portion of the calendar year, the EE value for that portion of the calendar year shall be equal to zero (e.g., if EEi = -100, then EEi = 0).
NR 409.065(8)(a)3.3. Sum all EEi values for the calendar year:
(Equation 4)
where:
EE is the excess emissions for NOx for the year (in tons)
n is the number of time periods during which a unit is subject to different emission limitations
