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.
