Ariz. Admin. Code § R18-2-101 - Definitions
The following definitions apply to this Chapter. Where the same term is defined in this Section and in the definitions Section for an Article of this Chapter, the Article-specific definition shall apply.
1. "Act" means the Clean Air Act of 1963
(P.L. 88-206; 42 U.S.C.
7401 through
7671q) as amended through December
31, 2011 (and no future editions).
2. "Actual emissions" means the actual rate
of emissions of a regulated NSR pollutant from an emissions unit, as determined
in subsections (2)(a) through (e), except that this definition shall not apply
for calculating whether a significant emissions increase as defined in
R18-2-401 has occurred, or for
establishing a plantwide applicability limitation as defined in
R18-2-401 . Instead, the
definitions of projected actual emissions and baseline actual emissions in
R18-2-401 shall apply for those
purposes.
a. In general, actual emissions as
of a particular date shall equal the average rate, in tons per year, at which
the unit actually emitted the pollutant during a consecutive 24-month period
that precedes the particular date and that is representative of normal source
operation. The Director may allow the use of a different time period upon a
determination that it is more representative of normal source operation. Actual
emissions shall be calculated using the unit's actual operating hours,
production rates, and types of materials processed, stored or combusted during
the selected time period.
b. The
Director may presume that source-specific allowable emissions for the unit are
equivalent to the actual emissions of the unit.
c. For any emissions unit that is or will be
located at a source with a Class I permit and has not begun normal operations
on the particular date, actual emissions shall equal the unit's potential to
emit on that date.
d. For any
emissions unit that is or will be located at a source with a Class II permit
and has not begun normal operations on the particular date, actual emissions
shall be based on applicable control equipment requirements and projected
conditions of operation.
e. This
definition shall not apply for calculating whether a significant emissions
increase has occurred, or for establishing a PAL. Instead, the definitions of
projected actual emissions and baseline actual emissions in
R18-2-401 shall apply for those
purposes.
