Abstract
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.

40 CFR Part 70
[EPA-R09-OAR-2022-0916; FRL-10530-01-R9]
Clean Air Act Operating Permit Program; California; South Coast
Air Quality Management District
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: 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.

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.

I. Background
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 (PM<INF>10</INF>), fine particulate matter with an
aerodynamic diameter of less than or equal to 2.5 micrometers
(PM<INF>2.5</INF>), 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 (NO<INF>2</INF>), carbon monoxide (CO), and sulfur
dioxide (SO<INF>2</INF>). 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 8-hour
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).

\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 PM<INF>2.5</INF>, SO<INF>2</INF>, 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.

3001...................................... Title V Permits--Applicability.... 12/4/2020 2/25/2021
----------------------------------------------------------------------------------------------------------------
\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.
