Current through Register Vol. 50, No. 6, June 20, 2024
A. Applicability Procedures
1. The requirements of this Section apply to
				the construction of any new
major stationary source
, as
				defined in Subsection B of this Section, or any project at an existing
major stationary source
in an area designated as attainment or
				unclassifiable under Sections 107(d)(1)(A)(ii) or (iii) of the Clean Air
				Act.
2. The requirements of
				Subsections J-R of this Section apply to the construction of any new major
				stationary source or the major modification of any existing major stationary
				source, except as this Section otherwise provides.
3. No new major stationary source or major
				modification to which the requirements of Subsection J-Paragraph R.5 of this
				Section apply shall begin actual construction without a permit that states that
				the major stationary source or major modification will meet those requirements.
				The administrative authority has authority to issue any such permit.
4. The requirements of the program will be
				applied in accordance with the following principles.
a. Except as otherwise provided in Paragraph
				A.5 of this Section, and consistent with the definition of
major
				modification
contained in Subsection B of this Section, a project is a
				major modification for a regulated new source review (NSR) pollutant if it
				causes two types of emissions increases- a
significant
emissions increase, as defined in Subsection B of this Section, and a
				significant
net emissions increase
, as defined in Subsection B
				of this Section. 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.
b. The procedure for calculating, before
				beginning actual construction, whether a significant emissions increase (i.e.,
				the first step of the process) will occur depends upon the type of emissions
				units being modified, according to Subparagraphs A.4.c-f of this Section. The
				procedure for calculating, before beginning actual construction, whether a
				significant net emissions increase will occur at the major stationary source
				(i.e., the second step of the process) is as defined in Subsection
				B.
Net Emissions Increase
of this Section. Regardless of any
				such preconstruction projections, a major modification results if the project
				causes a significant emissions increase and a significant net emissions
				increase.
c.
				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
, as defined in Subsection B of this
				Section, and the
baseline actual emissions
, as defined in
				Subparagraphs B.
Baseline Actual Emissions
.a and b of this
				Section, for each existing emissions unit, equals or exceeds the
significant
amount for that pollutant, as defined in
				Subsection B of this Section.
d.
				Actual-to-Potential Test for Projects That Only Involve Construction of a New
				Emissions Unit. A significant emissions increase of a regulated NSR pollutant
				is projected to occur if the sum of the difference between the
potential to emit
, as defined in Subsection B of this Section,
				from each new emissions unit following completion of the project and the
baseline actual emissions
, as defined in Subparagraph
				B.
Baseline Actual Emissions
.c of this Section, of these units
				before the project equals or exceeds the
significant
amount
				for that pollutant, as defined in Subsection B of this Section.
e. Reserved.
f. Hybrid Test for Projects That Involve
				Multiple Types of Emissions Units. 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 Subparagraphs
				A.4.c-d of this Section as applicable with respect to each emissions unit, for
				each type of emissions unit equals or exceeds the significant amount for that
				pollutant, as defined in Subsection B of this Section.
5. For any major stationary source for a
				plantwide applicability limit (PAL) for a regulated NSR pollutant, the major
				stationary source shall comply with the requirements under Subsection AA of
				this Section.
