35 Ill. Adm. Code 203.1320
Projected Actual Emissions
Section 203.1320Â Projected Actual Emissions
a)Â Â Â Â Â Â Â Â "Projected
actual emissions" means the maximum annual rate, in tons per year, at
which an existing emissions unit is projected to emit a regulated NSR pollutant
in any one of the 5 years (12-month period) following the date the unit resumes
regular operation after the project, or in any one of the 10 years following
that date, if the project involves increasing the emissions unit's design
capacity or its potential to emit that regulated NSR pollutant and full
utilization of the unit would result in a significant emissions increase or a
significant net emissions increase at the major stationary source.
b)Â Â Â Â Â Â Â Â In determining the projected actual emissions
under subsection (a) (before beginning actual construction), the owner or
operator of the major stationary source:
1)Â Â Â Â Â Â Â Â Shall consider all relevant information,
including, but not limited to, historical operational data, the company's own
representations, the company's expected business activity and the company's
highest projections of business activity, the company's filings with the State
or federal regulatory authorities, and compliance plans under Illinois' SIP;
and
2)Â Â Â Â Â Â Â Â Shall
include fugitive emissions to the extent quantifiable, and emissions associated
with startups, shutdowns, and malfunctions; and
3)Â Â Â Â Â Â Â Â Shall
exclude, in calculating any increase in emissions that results from the
particular project, that portion of the unit's emissions following the project
that an existing unit could have accommodated during the consecutive 24-month
period used to establish the baseline actual emissions under Section 203.1070
and that are also unrelated to the particular project, including any increased
utilization due to product demand growth; or
4)Â Â Â Â Â Â Â Â In
lieu of using the method set out in subsections (b)(1) through (b)(3), may
elect to use the emissions unit's potential to emit, in tons per year, as
defined under Section 203.1290.
