I. Background and Purpose
On October 26, 2015, the EPA promulgated a revised ozone NAAQS of
0.070 parts per million (ppm).\1\ Upon promulgation of a new or revised
NAAQS, the CAA requires the EPA to designate as nonattainment any area
that is violating the NAAQS based on the three most recent years of
ambient
[[Page 7319]]
air quality data. This action relates to Clark County, which was
designated nonattainment for the 2015 ozone NAAQS on June 4, 2018.\2\
Within Clark County, the Las Vegas Valley \3\ was classified as a
``Marginal'' ozone nonattainment area for the 2015 ozone NAAQS. On
January 5, 2023, the area was reclassified by operation of law to a
``Moderate'' ozone nonattainment area for failing to attain the 2015
ozone NAAQS by the applicable attainment date.\4\ However, because the
Department certified that its SIP-approved NNSR program satisfies the
requirements for a Marginal area only, this action is only proposing to
approve the Department's certification as it pertains to a Marginal
ozone nonattainment area.
---------------------------------------------------------------------------
\1\ 80 FR 65292 (October 26, 2015).
\2\ 83 FR 25776 (June 4, 2018).
\3\ The Las Vegas Valley is the portion of Clark County referred
to as Hydrographic Area 212. Hydrographic areas are shown on the
State of Nevada Division of Water Resources' map titled ``Water
Resources and Inter-basin Flows'' (September 1971).
\4\ 88 FR 775 (January 5, 2023).
---------------------------------------------------------------------------
On December 6, 2018, the EPA issued a final rule entitled,
``Implementation of the 2015 National Ambient Air Quality Standards for
Ozone: Nonattainment Area State Implementation Plan Requirements,''
(``2015 SIP Requirements Rule'') which establishes the requirements and
deadlines that state, tribal, and local air quality management agencies
must meet as they develop implementation plans for areas where ozone
concentrations exceed the 2015 ozone NAAQS.\5\ Based on the initial
nonattainment designation for the 2015 ozone standards, the Department
was required to make a SIP revision addressing NNSR no later than
August 3, 2021.\6\ This requirement may be met by submitting a SIP
revision consisting of a new or revised NNSR permit program, or an
analysis demonstrating that the existing SIP-approved NNSR permit
program meets the applicable 2015 ozone requirements and a letter
certifying the analysis.
---------------------------------------------------------------------------
\5\ 83 FR 62998 (December 6, 2018). The 2015 SIP Requirements
Rule addresses a range of nonattainment area SIP requirements for
the 2015 ozone NAAQS, including requirements pertaining to
attainment demonstrations, reasonable further progress (RFP),
reasonably available control technology, reasonably available
control measures, major new source review, emission inventories, and
the timing of SIP submissions and of compliance with emission
control measures in the SIP.
\6\ 40 CFR 51.1314.
---------------------------------------------------------------------------
II. The State's Submittal
A. What did the State submit?
The submitted 2015 Ozone Certification letter addressed by this
proposal was adopted by the Department on July 20, 2021. It was
submitted by the Nevada Division of Environmental Protection (NDEP),
the agency that serves as the governor's designee for Nevada SIP
submittals, on August 5, 2021, by a letter dated August 3, 2021.
NDEP's August 5, 2021 submittal of the Clark County DES 2015 Ozone
Certification letter was deemed by operation of law to meet the
completeness criteria in 40 CFR part 51, Appendix V on February 5,
2022, which must be met before formal EPA review.
B. What is the purpose of the submitted certification letter?
The Department's submittal is intended to satisfy the 2015 SIP
Requirements Rule that requires States to make a SIP revision
addressing NNSR. The Department's portion of the Nevada SIP currently
contains its NNSR permit program that was approved in 2014, prior to
the Las Vegas Valley's current ozone nonattainment designation.\7\ The
submitted certification letter provides a mechanism for the Department
to satisfy the 40 CFR 51.1314 submittal requirements based on its 2015
Marginal ozone nonattainment designation. The EPA's analysis of how
this SIP revision addresses the NNSR requirements for the 2015 ozone
NAAQS is provided below.
---------------------------------------------------------------------------
\7\ 79 FR 62350 (October 17, 2014).
---------------------------------------------------------------------------
III. Analysis of Nonattainment New Source Review Requirements
NNSR is a preconstruction review permit program that applies to new
major stationary sources or major modifications at existing sources
within a nonattainment area and is required under CAA sections
172(c)(5) and 173.
As mentioned in Section I of this notice, NNSR permit program
requirements were adopted for the 2015 ozone NAAQS at 40 CFR 51.1314 as
part of the 2015 SIP Requirements Rule.\8\ The minimum SIP requirements
for NNSR permitting programs for the 2015 ozone NAAQS are contained in
40 CFR 51.165. These NNSR program requirements include those
promulgated in the 2015 SIP Requirements Rule implementing the 2015
ozone NAAQS. The SIP for each ozone nonattainment area must contain
NNSR provisions that: (1) set major source thresholds for nitrogen
oxides (NO<INF>X</INF>) and volatile organic compounds (VOC) pursuant
to 40 CFR 51.165(a)(1)(iv)(A)(1)(i)-(iv) and (2); (2) classify physical
changes as a major source if the change would constitute a major source
by itself pursuant to 40 CFR 51.165(a)(1)(iv)(A)(3); (3) consider any
significant net emissions increase of NO<INF>X</INF> as a significant
net emissions increase for ozone pursuant to 40 CFR 51.165(a)(1)(v)(E);
(4) consider any increase of VOC emissions in Extreme ozone
nonattainment areas as a significant net emissions increase and a major
modification for ozone pursuant to 40 CFR 51.165(a)(1)(v)(F); (5) set
significant emissions rates for VOC and NO<INF>X</INF> as ozone
precursors pursuant to 40 CFR 51.165(a)(1)(x)(A)-(C) and (E); (6)
contain provisions for emissions reductions credits pursuant to 40 CFR
51.165(a)(3)(ii)(C)(1)-(2); (7) provide that the requirements
applicable to VOC also apply to NO<INF>X</INF> pursuant to 40 CFR
51.165(a)(8); (8) set offset ratios for VOC and NO<INF>X</INF> pursuant
to 40 CFR 51.165(a)(9)(ii)-(iv); and (9) require public participation
procedures compliant with 40 CFR 51.165(i).
---------------------------------------------------------------------------
\8\ 83 FR 62998 (December 6, 2018).
---------------------------------------------------------------------------
The Department's SIP-approved NNSR program,\9\ established in
Section 12.3 of the Clark County Air Quality Regulations, applies to
the construction and modification of stationary sources, including
major stationary sources in nonattainment areas under its jurisdiction.
The Department's submitted SIP revision includes a compliance
demonstration, consisting of a table listing each of the 2015 ozone
NAAQS NNSR SIP requirements from 40 CFR 51.165 and a citation to the
specific provision of the rule satisfying the requirement. The
submittal also includes a certification by the Department that the
cited rules meet the federal NNSR requirements for the Marginal ozone
nonattainment designation. These documents, including our Summary of
Evaluation \10\ of the Department's submittal, are available in the
docket for this action.
---------------------------------------------------------------------------
\9\ 79 FR 62350 (October 17, 2014).
\10\ Our review of the Department's submittal is included in a
Memorandum to Docket EPA-R09-OAR-2022-0494, titled ``EPA Summary of
Evaluation--Clark County Department of Environment and
Sustainability 2021 Ozone Certification,'' dated November 28, 2023.
---------------------------------------------------------------------------
The EPA has reviewed the demonstration and cited program elements
intended to meet the federal NNSR requirements for the 2015 ozone NAAQS
and is proposing to approve the Department's submittal because the
current SIP-approved NNSR program satisfies all the 2015 SIP
Requirements Rule NNSR program requirements applicable to the Las Vegas
Valley as a Marginal ozone nonattainment area.
IV. Proposed Action and Public Comment
The EPA is proposing to approve a SIP revision addressing the NNSR
requirements for the 2015 ozone
[[Page 7320]]
NAAQS for the Department. In support of this proposed action, we have
concluded that our approval of the submitted 2015 ozone certification
for the Department would comply with section 110(l) of the Act because
our approval of the ozone certification will not interfere with
continued attainment or maintenance of the NAAQS in the Department.
Similarly, we find that the submitted revision is approvable under
section 193 of the Act because it does not modify any control
requirement in effect before November 15, 1990, without ensuring
equivalent or greater emission reductions. The EPA has concluded that
the State's submission fulfills the 40 CFR 51.1314 revision requirement
and meets the requirements of CAA sections 110, 172(c)(5), 173,
182(a)(2)(C), 193, and the minimum SIP requirements of 40 CFR 51.165.
If we finalize this action as proposed, our action will incorporate
this certification into the federally enforceable SIP and be codified
through revisions to 40 CFR 52.1470 (Identification of plan).
The EPA has made, and will continue to make, the State's submission
and all other materials available electronically through <a href="https://www.regulations.gov">https://www.regulations.gov</a> and at the EPA Region IX Office (please contact the
person identified in the FOR FURTHER INFORMATION CONTACT section of
this preamble for more information). We will accept comments from the
public on this proposal until March 4, 2024.
V. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, the EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this proposed action merely proposes to approve state law
as meeting federal requirements and does not impose additional
requirements beyond those imposed by state law. For that reason, this
proposed action:
<bullet> Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 14094 (88 FR 21879, April 11, 2023);
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
<bullet> Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it proposes to approve a state program;
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act.
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where the EPA or an Indian tribe
has demonstrated that a tribe has jurisdiction. In those areas of
Indian country, the rule does not have tribal implications and will not
impose substantial direct costs on tribal governments or preempt tribal
law as specified by Executive Order 13175 (65 FR 67249, November 9,
2000).
Executive Order 12898 (Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
Feb. 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
The EPA defines environmental justice (EJ) as ``the fair treatment and
meaningful involvement of all people regardless of race, color,
national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' The EPA further defines the term fair treatment to mean
that ``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
The State did not evaluate environmental justice considerations as
part of its SIP submittal; the CAA and applicable implementing
regulations neither prohibit nor require such an evaluation. The EPA
did not perform an EJ analysis and did not consider EJ in this action.
Consideration of EJ is not required as part of this action, and there
is no information in the record inconsistent with the stated goal of
E.O. 12898 of achieving environmental justice for people of color, low-
income populations, and Indigenous peoples.
