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:

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.
(10) "Heat input" means the product,
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).
(B) The fuel feed rate into a combustion
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*.
Heat input does not include the heat derived from preheated
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.
(12) "Maximum design heat
input" means the maximum amount of fuel per hour, in million British thermal
units per hour (MMBtu/hr), that a unit is capable of combusting on a steady
state basis as of the initial installation of the unit as specified by the
manufacturer of the unit.
(13)
"Nameplate capacity" means the maximum electrical generating output, expressed
in megawatt electrical (MWe) output, that a generator can sustain over a
specified period of time when not restricted by seasonal or other deratings as
measured in accordance with the United States Department of Energy
standards.
(14) "Operator" means
any person who operates, controls, or supervises the operation of a unit,

(18) "Replacement",
"replace", or "replaced" means the demolition of, or the permanent shutdown and
