Authority: IC 13-14-8; IC 13-17-3
Affected: IC 13-11; IC 13-15; IC 13-17
Sec. 2.
(a) The
requirements of sections 3 through 5, 7, 8, 10, 14, and 15 of this rule apply
to the construction of any new major stationary source or the major
modification of any existing major stationary source except as this rule
otherwise provides.
(b) The
requirements of this rule apply to the construction of any new major stationary
source or any project at an existing major stationary source in an area
designated as attainment or unclassifiable in 326 IAC 1-4.
(c) No new major stationary source or major
modification to which the requirements of sections 3 through 5, 7, 8(a), 10,
14, and 15 of this rule apply shall begin actual construction without a permit
that states that the major stationary source or major modification will meet
the requirements of sections 3 through 5, 7, 8(a), 10, 14, and 15 of this
rule.
(d) The requirements of this
rule will be applied in accordance with the following:
(1) Except as otherwise provided in
subsection (e), and consistent with the definition of major modification
contained in section 1(dd) of this rule, a project is a major modification for
a regulated NSR pollutant if it causes both a significant emissions increase
and a significant net emissions increase. The project is not a major
modification if it does not cause a significant emissions increase. If the
project causes a significant emissions increase, then the project is a major
modification only if it also results in a significant net emissions
increase.
(2) Prior to beginning
actual construction, the procedure for calculating if a significant emissions
increase will occur depends upon the type of emissions units being modified as
provided in subdivisions (3) through (5). The procedure for calculating, before
beginning actual construction, if a significant net emissions increase will
occur at the major stationary source is contained in section 1(ii) of this
rule. Regardless of any preconstruction projections, a major modification
results if the project causes a significant emissions increase and a
significant net emissions increase.
(3) For an actual-to-projected-actual
applicability test for projects that only involve existing emissions units, a
significant emissions increase of a regulated NSR pollutant is projected to
occur if the sum of the difference between the projected actual emissions and
the baseline actual emissions for each existing emissions unit equals or
exceeds the significant amount for that pollutant.
(4) For an actual-to-potential applicability
test for projects that only involve construction of new emissions units, a
significant emissions increase of a regulated NSR pollutant is projected to
occur if the sum of the difference between the potential to emit from each new
emissions unit following completion of the project and the baseline actual
emissions of these units before the project equals or exceeds the significant
amount for that pollutant.
(5) For
projects that involve a combination of emission units using the tests in
subdivisions (3) and (4), a significant emissions increase of a regulated NSR
pollutant is projected to occur if the sum of the emissions increases for each
emissions unit, using the method specified in subdivisions (3) and (4), as
applicable, with respect to each emissions unit, for each type of emissions
unit equals or exceeds the significant amount for that pollutant.
(e) For any major stationary
source for which a PAL has been established for a regulated NSR pollutant, the
major stationary source shall comply with the requirements under 326 IAC
2-2.4.
(f) Sources that are located
in or proposed to be located in an area designated as nonattainment under 326
IAC 1-4 for a pollutant shall be exempt from the requirements of this rule for
that particular pollutant and subject to 326 IAC 2-3.
(g) A source or modification of a source that
is or would be a nonprofit health or nonprofit educational institution shall be
exempt from the requirements of sections 3, 4, and 7 of this rule.
(h) The requirements of sections 3 through 5,
7, 8, 10, 14, and 15 of this rule do not apply to a particular major stationary
source or major modification if the source or modification is a portable
stationary source that has previously received a permit under 326 IAC 2-5.1-3
or 326 IAC 2-7 and the permit contains conditions from 40 CFR Part 52.21* or
this rule if:
(1) the source proposes to
relocate and emissions of the source at the new location would be
temporary;
(2) the emissions from
the source would not exceed its allowable emissions;
(3) emissions from the source would impact no
Class I area and no area where an applicable increment is known to be violated;
and
(4) ten (10) days advance
notice is given to the department prior to the relocation identifying the
proposed new location and probable duration of the operation at the new
location.
