(A) General provisions. In lieu of complying
			 with the applicable emission limitation in rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code, any affected units subject to such emission
			 limitation, under control of the same owner or operator, and having the same
			 designated representative may average their NOx
			 emissions under an averaging plan approved under this rule.
(1) Each affected unit included in an
			 averaging plan for phase II shall be a boiler subject to an emission limitation
			 in rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code for all years for which the unit is included in the
			 plan.
(2) Each unit included in an
			 averaging plan shall have an alternative contemporaneous annual emission
			 limitation (pound per MMBtu) and can only be included in one averaging
			 plan.
(3) Each unit included in an
			 averaging plan shall have a minimum allowable annual heat input value (MMBtu),
			 if it has an alternative contemporaneous annual emission limitation more
			 stringent than that unit's applicable emission limitation under rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code, and a maximum allowable annual heat input value, if
			 it has an alternative contemporaneous annual emission limitation less stringent
			 than that unit's applicable emission limitation under rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code.
(4) The
			 Btu-weighted annual average emission rate for the units in an averaging plan
			 shall be less than or equal to the Btu-weighted annual average emission rate
			 for the same units had they each been operated, during the same period of time,
			 in compliance with the applicable emission limitations in rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code.
(5) In
			 order to demonstrate that the proposed plan is consistent with paragraph (A)(4)
			 of this rule, the alternative contemporaneous annual emission limitations and
			 annual heat input values assigned to the units in the proposed averaging plan
			 shall meet the following requirement:

where:
RLi = alternative contemporaneous annual
				emission limitation for unit i, in pound per MMBtu, as specified in the
				averaging plan;
Rli = applicable emission limitation for
				unit i, in pound per MMBtu, as specified in rule
				3745-103-57,
				3745-103-58,
				or
				3745-103-59
				of the Administrative Code 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 rule
				3745-103-57
				or
				3745-103-59
				of the Administrative Code;
HIi = annual heat input for unit i, in
				MMBtu, as specified in the averaging plan;
n = number of units in the averaging plan.
(6) For units with an alternative emission
			 limitation, RLi shall equal the applicable emissions
			 limitation under rule
			 3745-103-57,
			 3745-103-58,
			 or
			 3745-103-59
			 of the Administrative Code, not the alternative emissions limitation.
(7) No unit may be included in more than one
			 averaging plan.
