326 IAC 2-3-1 - Definitions
Authority: IC 13-14-8; IC 13-17-3
Affected: IC 13-15; IC 13-17
Sec. 1.
(a) The
definitions in this section apply throughout this rule.
(b) "Actual emissions " means the actual rate
of emissions of a regulated NSR pollutant from an emissions unit as determined
in accordance with the following:
(1) 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 twenty-four (24) month period that:
(A) precedes the particular date;
and
(B) is representative of normal
source operation .
The commissioner shall allow the use of a different time
period upon a determination that it is more representative of normal source
(2) The commissioner may presume that
source-specific allowable emissions for the unit are equivalent to the actual
emissions of the unit.
(3) For any
emissions unit that has not begun normal operations on the particular date,
actual emissions shall equal the potential to emit of the unit on that
date.
(4) The term shall not apply
for calculating a significant emissions increase under section 2(c) of this
rule or for establishing a PAL under
326 IAC 2-3.4. Instead, subsections (d) and (kk) shall
apply for those purposes.
(c) "Allowable emissions " means the emissions
rate of a source calculated using the maximum rated capacity of the source
unless a source is subject to enforceable permit limits that restrict the
operating rate or hours of operation , or both, and the most stringent of the
following:
(1) The applicable standards as
set forth in 40 CFR Part 60, New Source Performance Standards (NSPS)*, and 40
CFR Part 61, National Emission Standards for Hazardous Air Pollutants
(NESHAPS)*.
(2) The emissions
limitation imposed by any rule in this title, including those with a future
compliance date.
(3) The emissions
rate specified as an enforceable permit condition, including those with a
future compliance date.
(d) "Baseline actual emissions " means the
rate of emissions, in tons per year, of a regulated NSR pollutant , as
determined as follows:
(1) For any existing
electric utility steam generating unit , the term means the average rate, in
tons per year, at which the unit actually emitted the pollutant during any
consecutive twenty-four (24) month period selected by the owner or operator
within the five (5) year period immediately preceding when the owner or
operator begins actual construction of the project . The commissioner may allow
the use of a different time period upon a determination that it is more
representative of normal source operation . The baseline actual emissions shall
be determined in accordance with the following:
(A) The average rate shall include fugitive
emissions to the extent quantifiable and emissions associated with start-ups,
shutdowns, and malfunctions to the extent they are affected by the
project .
(B) The average rate shall
be adjusted downward to exclude any noncompliant emissions that occurred while
the source was operating above any emission limitation that was legally
enforceable during the consecutive twenty-four (24) month period.
(C) For a regulated NSR pollutant , when a
project involves multiple emissions units, only one (1) consecutive twenty-four
(24) month period may be used to determine the baseline actual emissions for
the emissions units being changed. A different consecutive twenty-four (24)
month period can be used for each regulated NSR pollutant .
(D) The average rate shall not be based on
any consecutive twenty-four (24) month period for which there is inadequate
information available for determining annual emissions, in tons per year, and
for adjusting this amount if required by clause (B).
(2) For an existing emissions unit , other
than an electric utility steam generating unit , the term means the average
rate, in tons per year, at which the emissions unit actually emitted the
pollutant during any consecutive twenty-four (24) month period selected by the
owner or operator within the ten (10) year period immediately preceding either
the date the owner or operator begins actual construction of the project or the
date a complete permit application is received by the department for a permit
required under
326 IAC 2-3,
except that the ten (10) year period shall not include any period earlier than
November 15, 1990. The baseline actual emissions shall be determined in
accordance with the following:
(A) The average
rate shall include fugitive emissions to the extent quantifiable and emissions
associated with start-ups, shutdowns, and malfunctions and to the extent they
are affected by the project .
(B)
The average rate shall be adjusted downward to exclude any noncompliant
emissions that occurred while the source was operating above an emission
limitation that was legally enforceable during the consecutive twenty-four (24)
month period.
(C) The average rate
shall be adjusted downward to exclude any emissions that would have exceeded an
emission limitation with which the major stationary source must currently
comply had the major stationary source been required to comply with the
limitations during the consecutive twenty-four (24) month period. However, if
an emission limitation is part of a maximum achievable control technology
standard that the U.S. EPA proposed or promulgated under 40 CFR Part 63 *, the
baseline actual emissions need only be adjusted if the state has applied the
emissions reduction to an attainment demonstration or maintenance plan
consistent with the requirements of section 3(b)(12) of this rule.
(D) For a regulated NSR pollutant , when a
project involves multiple emissions units, only one (1) consecutive twenty-four
(24) month period must be used to determine the baseline actual emissions for
the emissions units being changed. A different consecutive twenty-four (24)
month period can be used for each regulated NSR pollutant .
(E) The average rate shall not be based on
any consecutive twenty-four (24) month period for which there is inadequate
information available for determining annual emissions, in tons per year, and
for adjusting this amount if required by clauses (B) and (C).
(3) For a new emissions unit , the
baseline actual emissions for purposes of determining the emissions increase
that will result from the initial construction and operation of the unit shall
equal zero (0) and thereafter, for all other purposes, shall equal the unit's
potential to emit .
(4) For a PAL
for a major stationary source , the baseline actual emissions shall be
calculated for existing electric utility steam generating units in accordance
with the procedures contained in subdivision (1), for other existing emissions
units in accordance with the procedures contained in subdivision (2), and for a
new emissions unit in accordance with the procedures contained in subdivision
(3).
(e) "Begin actual
construction " means, in general, initiation of physical on-site construction
activities on an emissions unit that are of a permanent nature. These
activities include, but are not limited to, the following:
(1) Installation of building supports and
foundations.
(2) Laying underground
pipework.
(3) Construction of
permanent storage structures.
With respect to a change in method of operations, the term refers to those on-site activities, other than preparatory activities, that mark the initiation of the change.
(f) "Best available control technology " or
"BACT " means an emissions limitation, including a visible emission standard,
based on the maximum degree of reduction for each regulated NSR pollutant that
would be emitted from any proposed major stationary source or major
modification that the commissioner, on a case-by-case basis, taking into
account energy, environmental, and economic impacts and other costs, determines
is achievable for the source or modification through application of production
processes or available methods, systems, and techniques, including fuel
cleaning or treatment or innovative fuel combustion techniques for control of
the pollutant. In no event shall application of BACT result in emissions of any
pollutant that would exceed the emissions allowed by any applicable standard
under 40 CFR Part 60* or 40 CFR Part 61*. If the commissioner determines that
technological or economic limitations on the application of measurement
methodology to a particular emissions unit would make the imposition of an
emissions standard infeasible, a design, equipment, work practice, operational
standard, or combination thereof may be prescribed instead to satisfy the
requirement for the application of BACT . The standard shall, to the degree
possible, set forth the emissions reduction achievable by implementation of the
design, equipment, work practice, or operation and shall provide for compliance
by means that achieve equivalent results.

steam-electric generator that would produce electrical energy for sale is also
considered in determining the electrical energy output capacity of the affected
facility.
(r) "Emissions unit "
means any part of a stationary source that emits or would have the potential to
emit any regulated NSR pollutant . For purposes of this rule, there are the
following two (2) types of emissions units:
