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
new source review (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 preceding the particular date and representative of normal source
operation. The department shall 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.
(2) The
department 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(d) of this rule or for
establishing a
PAL under 326 IAC
2-2.4. Instead, subsections (e) and (pp) shall
apply for those purposes.
(c) "
Adverse impact on visibility" means
visibility impairment that interferes with the management, protection,
preservation, or enjoyment of the visitor's visual experience of the federal
Class I area as defined in section 13 of this rule. This determination must be
made on a case-by-case basis taking into account the geographic extent,
intensity, duration, frequency, and time of visibility impairment, and how
these factors correlate with:
(1) times of
visitor use of the federal Class I area; and
(2) the frequency and timing of natural
conditions that reduce visibility.
(d) "
Allowable emissions" means the emissions
rate of a stationary 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:
(1) applicable standards as set forth in
40 CFR Part
60 * and 40 CFR Part
61 *;
(2) SIP emissions limitation, including those
with a future compliance date; or
(3) emissions rate specified as an
enforceable permit condition, including those with a future compliance
date.
(e) "Baseline
actual emissions" means the rate of emissions, in tons per year, of a regulated
NSR pollutant, as determined in accordance with the following:
(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 shall 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
by this rule, 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 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 department has applied the emissions reductions to
an attainment demonstration or maintenance plan consistent with the
requirements of 326 IAC
2-3-3(b)(12).
(D) 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
all 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 stationary source, the baseline
actual emissions shall be calculated as
follows:
(A) For an existing electric utility
steam generating unit, in accordance with subdivision (1).
(B) For an existing emissions unit except an
existing electric utility steam generating unit, in accordance with subdivision
(2).
(C) For a new emissions unit,
in accordance with subdivision (3).

for the pollutant for which the baseline date is established:
(A) equal to or greater than one (1)
microgram per cubic meter ([MICRO]g/m3) (annual
average) for sulfur dioxide (SO2), nitrogen dioxide
(NO2), or PM10; or
(B) equal to or greater than three-tenths
(0.3) microgram per cubic meter ([MICRO]g/m3)

1-4 and
Section 107(d)(1)(D) or 107(d)(1)(E) of the CAA cannot intersect or be smaller
than the area of impact of any
major stationary source or
major modification
that:
(A) establishes a minor source baseline
date; or
(B) is subject to 40 CFR
Part
52.21 * and this rule and would be constructed in the same state as the
state proposing the redesignation.
(3) Any
baseline area established originally
for the total suspended particulate (TSP) increments shall remain in effect and
shall apply for purposes of determining the amount of available
PM
10 increments, except that the
baseline area shall not
remain in effect if the U.S. EPA rescinds the corresponding
minor source
baseline date in accordance with 40 CFR Part
52.21(b)(14)(iv) *.
(g) "
Baseline concentration" means
that ambient concentration level that exists in the
baseline area at the time
of the applicable
minor source baseline date. A baseline concentration is
determined for each pollutant for which a
minor source baseline date is
established and shall include the following:
(1) The actual emissions, as defined in
subsection (b), representative of sources in existence on the applicable minor
source baseline date except as provided in subdivision (3).
(2) The allowable emissions of major
stationary sources that commenced construction before the major source baseline
date, but were not in operation by the applicable minor source baseline
date.
(3) The following will not be
included in the
baseline concentration and will affect the applicable maximum
allowable increase or increases:
(A) Actual
emissions, as defined in subsection (b), from any major stationary source on

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 * and 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 not feasible, a design, equipment, work practice,
operational standard, or combination thereof may be prescribed instead to
satisfy the requirements 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.
