Clean Air Act Operating Permit
Program; California; South Coast Air
Quality Management District
Environmental Protection
Agency (EPA).
ACTION: Proposed rule.
AGENCY:
The Environmental Protection
Agency (EPA) is proposing approval of
revisions to the Clean Air Act (CAA or
‘‘Act’’) Operating Permit Program (title
V) of the South Coast Air Quality
Management District (SCAQMD or
‘‘District’’) in California. Once approved
by the EPA, these program revisions
will modify the major source title V
potential to emit (PTE) thresholds to
conform with the recent reclassification
of state lands within the Coachella
Valley nonattainment area from
‘‘Severe-15’’ to ‘‘Extreme’’
nonattainment for the 1997 8-hour
ozone national ambient air quality
standards (NAAQS). In the ‘‘Rules and
Regulations’’ section of this issue of the
Federal Register, we are simultaneously
publishing an approval of the District’s
title V program revisions without a prior
proposed rule. If the EPA receives no
adverse comment, it will not take
further action on this proposed rule.
DATES: Comments must be received on
or before August 19, 2024.
ADDRESSES: Submit your comments,
identified by Docket ID No. EPA–R09–
OAR–2022–0916 at https://
www.regulations.gov. For comments
submitted at Regulations.gov, follow the
online instructions for submitting
comments. Once submitted, comments
cannot be edited or removed from

SUPPLEMENTARY INFORMATION:
Throughout this document, ‘‘we,’’ ‘‘us,’’
and ‘‘our’’ refer to the EPA. This
proposal addresses the following local
rule: SCAQMD Rule 3001, ‘‘Title V
Permits—Applicability.’’ In the Rules
and Regulations section of this Federal
Register, the EPA is approving the
District’s submissions and making
administrative updates as a direct final
rule without prior proposal because we
view this as a noncontroversial action
and anticipate no adverse comments. A
detailed rationale for the action is set
forth in the preamble to the direct final
rule. If the EPA receives no adverse
comments, the EPA contemplates no
further action. If the EPA receives
adverse comments, the EPA will
withdraw the direct final rule and will
address all public comments in a
subsequent final rule based on this
proposed rule. We do not plan to open
a second comment period on this action,
so anyone interested in commenting
should do so at this time. Please note
that if the EPA receives an adverse
comment on an amendment, paragraph,
or section of this proposed rule and if
that provision may be severed from the
remainder of the proposed rule, the EPA
may adopt as final those provisions of
the proposed rule that are not the
subject of an adverse comment. For
additional information, see the direct
final rule of the same title that is located
in the ‘‘Rules and Regulations’’ section
of this Federal Register.

II. What are the requirements for approval of
revisions to title V programs?
III. What is the State’s proposed title V
program revision?
I. Background
The CAA Amendments of 1990
include title V, which requires States to
develop an operating permits program
that meets the federal criteria codified
in title 40 of the Code of Federal
Regulations (CFR) part 70. The title V
program requires certain sources of air
pollution to obtain federal operating
permits from their respective states.
These federal operating permits improve
enforcement and compliance by
consolidating all applicable federal
requirements into one federally
enforceable document. Before a state
can issue permits under 40 CFR part 70
(which are referred to as ‘‘title V
permits’’), the EPA must approve its
programs under appendix A of 40 CFR
part 70. States may submit revisions to
their approved programs for EPA
approval.
Title V of the CAA applies to ‘‘major
stationary sources’’ as defined in title I,
part D of the Act. 40 CFR 70.2 bases the
definition of ‘‘major stationary source’’
on the nonattainment classification of
the area where the source is located.
Table 1 of this document shows the
attainment/nonattainment/
unclassifiable status for the applicable
NAAQS within the District’s
jurisdictional boundary. As shown in
Table 1, the SCAQMD’s jurisdiction is
classified as nonattainment for fine
particulate matter with an aerodynamic
diameter of less than or equal to 10
micrometers (PM10), fine particulate
matter with an aerodynamic diameter of
less than or equal to 2.5 micrometers
(PM2.5), lead (Pb), and ozone.1 The
SCAQMD’s jurisdiction is composed of
several air basins that have different
nonattainment classifications. The
District is designated attainment/
unclassifiable for nitrogen dioxide
(NO2), carbon monoxide (CO), and
sulfur dioxide (SO2). 40 CFR 81.305.
1 As discussed in the Summary of this proposed
rulemaking, the EPA reclassified state lands within
the Coachella Valley area from Severe-15 to an
Extreme ozone nonattainment area for the 1997 8hour ozone NAAQS, effective July 10, 2019. This
reclassification to Extreme means that a major
stationary source is now defined as a source
emitting 10 tons or more per year of either oxides
of nitrogen or volatile organic compounds. 84 FR
32841 (July 10, 2019).

III. What is the State's proposed title V program revision?
I. Background
The CAA Amendments of 1990 include title V, which requires States
to develop an operating permits program that meets the federal criteria
codified in title 40 of the Code of Federal Regulations (CFR) part 70.
The title V program requires certain sources of air pollution to obtain
federal operating permits from their respective states. These federal
operating permits improve enforcement and compliance by consolidating
all applicable federal requirements into one federally enforceable
document. Before a state can issue permits under 40 CFR part 70 (which
are referred to as ``title V permits''), the EPA must approve its
programs under appendix A of 40 CFR part 70. States may submit
revisions to their approved programs for EPA approval.
Title V of the CAA applies to ``major stationary sources'' as
defined in title I, part D of the Act. 40 CFR 70.2 bases the definition
of ``major stationary source'' on the nonattainment classification of
the area where the source is located. Table 1 of this document shows
the attainment/nonattainment/unclassifiable status for the applicable
NAAQS within the District's jurisdictional boundary. As shown in Table
1, the SCAQMD's jurisdiction is classified as nonattainment for fine
particulate matter with an aerodynamic diameter of less than or equal
to 10 micrometers (PM10), fine particulate matter with an
aerodynamic diameter of less than or equal to 2.5 micrometers
(PM2.5), lead (Pb), and ozone.\1\ The SCAQMD's jurisdiction
is composed of several air basins that have different nonattainment
classifications. The District is designated attainment/unclassifiable
for nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur
dioxide (SO2). 40 CFR 81.305.

\a\ NA = Nonattainment; A/U = Attainment or Unclassified.
\b\ On August 3, 2005, the EPA revoked the 1979 1-hour ozone NAAQS; however, the EPA is retaining the listing of
the designated areas for the revoked 1979 ozone NAAQS in 40 CFR part 81, for the sole purpose of identifying
the anti-backsliding requirements that may apply to the areas at the time of revocation. 70 FR 44470 (August
3, 2005).
\c\ On March 6, 2015, the EPA revoked the 1997 8-hour ozone NAAQS; however, the EPA is retaining the listing of
the designated areas for the revoked 1997 ozone NAAQS in 40 CFR part 81, for the sole purpose of identifying
the anti-backsliding requirements that may apply to the areas at the time of revocation. 80 FR 12264 (March 6,
2015). On July 10, 2019, the Coachella Valley was reclassified to Extreme ozone nonattainment for the 1997
ozone NAAQS. 84 FR 32841 (July 10, 2019).
The emissions thresholds, above which a title V operating permit is
required pursuant to 40 CFR 70.3(a), are shown in table 2.

\a\ 40 CFR 70.2.
The emissions thresholds for PM2.5, SO2, and
Pb are 100 tons per year (tpy) regardless of attainment classification.
For hazardous air pollutants (HAPs), the title V threshold is 10 tpy
for any individual HAP and 25 tpy for any combination of HAPs.
II. What are the requirements for approval of revisions to title V
programs?
Pursuant to 40 CFR 70.4(i), either the EPA or the state may
initiate a title V program revision ``when the relevant Federal or
State statutes or regulations are modified or supplemented.'' It is the
responsibility of the state to keep the EPA apprised of any proposed
modifications to its basic statutory or regulatory authority or
procedures. Revision of a state program shall be accomplished as
follows:
(a) The state submits a modified program description, attorney
general's statement (if necessary for expanded or additional
authority), or other documents as the EPA determines to be necessary.
40 CFR 70.4(i)(2)(i).
(b) After the EPA receives a proposed program revision, it will
publish a notice of the proposed change in the Federal Register and
provide for a public comment period of at least 30 days. 40 CFR
70.4(i)(2)(ii).
(c) The Administrator shall approve or disapprove program revisions
based on the requirements of 40 CFR part 70 and the Act. 40 CFR
70.4(i)(2)(iii).
(d) The EPA must publish a notice of approval in the Federal
Register for any substantial program revisions. 40 CFR 70.4(i)(2)(iv).
(e) Approval of nonsubstantial revisions may be given by a letter
from the Administrator to the Governor or a designee. 40 CFR
70.4(i)(2)(iv).
(f) A program revision shall become effective upon the approval of
the Administrator. 40 CFR 70.4(i)(2)(iv).
III. What is the State's proposed title V program revision?
Table 3 lists the rules submitted as part of the SCAQMD's title V
program revisions and the dates they were adopted by the District and
submitted to the EPA by the California Air Resources
[[Page 58692]]
Board (CARB), which is the Governor's designee for California rule
submittals.\2\
---------------------------------------------------------------------------
\2\ A detailed explanation of the EPA's evaluation of these
proposed revisions as well as a change copy of the revised rule can
be found in the Technical Support Document (TSD) and docket.

----------------------------------------------------------------------------------------------------------------
\a\ CARB transmitted the submittal to the EPA by a letter dated February 24, 2021.
The SCAQMD revised the title V emissions thresholds in its Rule
3001 for volatile organic compounds and oxides of nitrogen from 25 tpy
to 10 tpy for the Riverside County portion of the Salton Sea Air Basin
\3\ to align with a recent reclassification for that area from Severe-
15 to Extreme for the 1997 8-hour ozone NAAQS.
---------------------------------------------------------------------------
\3\ The area often referred to as the ``Coachella Valley''
consists of the Riverside County portion of the Salton Sea Air
Basin.
---------------------------------------------------------------------------
The District made two additional revisions to Rule 3001: (1)
clarifying the geographic areas for the Phase One and Phase Two
facilities; and (2) including an applicability cutoff date of December
4, 2020, for Phase One title V facilities.
