				device under clause (A) is combined cycle.
(5) "Commencing commercial operation" means,
				with regards to a unit that serves a generator, to have begun to produce steam,
				gas, or other heated medium used to generate electricity for sale or use,
				including test generation, subject to the following:
(A) For a unit that is a large affected unit,
				on the date the unit commences commercial operation, the date remains the
				unit's date of commencement of commercial operation even if the unit is
				subsequently modified, reconstructed, or repowered.
(B) For a unit that is not a large affected
				unit, on the date the unit commences commercial operation, the date that the
				unit becomes a large affected unit, as defined under subdivision 11, is the
				unit's date of commencement of commercial operation.
(C) Except as provided in clauses (A) and
				(B), for a unit not serving a generator producing electricity for sale, the
				unit's date of commencement of operation is the unit's date of commencement of
				commercial operation.
(6) "Commencing operation" means the
				following:
(A) A unit commences operation on
				either the date:
(i) of commencement of any
				mechanical, chemical, or electronic process, including start-up of a unit's
				combustion chamber; or
(ii) a unit
				meets the applicability criteria in section 1 of this rule, if the unit was in
				operation prior to the date on which it met the applicability criteria in
				section 1 of this rule.
(B) A unit that undergoes a physical change
				after the date the unit commences operation, other than replacement of the unit
				by a unit at the same source, retains the unit's date of commencement of
				operation, and is treated as the same unit.
(C) A unit that is replaced by a unit at the
				same source, such as repowered, after the date the unit commences operation
				retains the replaced unit's date of commencement, and the replacement unit is
				treated as a separate unit with a separate date for commencement of
				operation.
(7)
				"Designated representative" means the person who is authorized by the owner or
				operator of the unit to represent and legally bind the owner or operator in
				matters pertaining to this rule, following the procedures for authorization and
				the responsibilities of the designated representative in 40 CFR 72, Subpart B*,
				including the authorization of an alternate designated
				representative.
(8) "Fossil fuel"
				means natural gas, petroleum, coal, or any solid, liquid, or gaseous fuel
				derived from these materials.
(9)
				"Fossil fuel-fired" means the following:
(A)
				Except as provided in clause (B), the combustion of fossil fuel, alone or in
				combination with any other fuel, under any of the following scenarios:
(i) The fossil fuel actually combusted
				comprises more than fifty percent (50%) of the annual heat input on a British
				thermal unit (Btu) basis during any year starting in 1995. If a unit had no
				heat input in 1995, then during the last year of operation of the unit prior to
				1995.
(ii) The fossil fuel is
				projected to comprise more than fifty percent (50%) of the annual heat input on
				a Btu basis during any year, provided that the unit is fossil fuel-fired as of
				the date during the year that the unit begins combusting fossil fuel.
(B) For the purposes of
				determining applicability in section 1(b)(3) and 1(b)(4) of this rule,
				combusting any amount of fossil fuel in any calendar year.

				expressed in Btu per unit of time (Btu/hr), of the following:
(A) The gross calorific value of the fuel,
				expressed in Btu per pound (Btu/lb).

				device, expressed in mass of fuel per unit of time (lb/hr), as measured,
				recorded, and reported in accordance with 40 CFR 75, Subpart H*.

				  combustion air, recirculated flue gases, or exhaust from other sources.
(11) "Large affected
				unit" means a unit that meets the applicability criteria in section 1 of this
				rule.

				"replace", or "replaced" means the demolition of, or the permanent shutdown and
				permanent disabling of, a unit, and the construction of another unit, to be
				used instead of the demolished or shutdown unit.
