Federal Register / Vol. 88, No. 59 / Tuesday, March 28, 2023 / Proposed Rules
Executive Order 12866 and the
Presidential memorandum ‘‘Plain
Language in Government Writing’’
require each agency to write regulations
that are easy to understand.
The Secretary invites comments on
how to make the proposed priority
easier to understand, including answers
to questions such as the following:
D Are the requirements in the
proposed regulations clearly stated?
D Do the proposed regulations contain
technical terms or other wording that
interferes with their clarity?
D Does the format of the proposed
regulations (grouping and order of
sections, use of headings, paragraphing,
etc.) aid or reduce their clarity?
D Would the proposed regulations be
easier to understand if we divided them
into more (but shorter) sections?
D Could the description of the
proposed regulations in the
SUPPLEMENTARY INFORMATION section of
this preamble be more helpful in
making the proposed regulations easier
to understand? If so, how?
D What else could we do to make the
proposed regulations easier to
understand?
To send any comments about how the
Department could make these proposed
regulations easier to understand, see the
instructions in the ADDRESSES section.
Regulatory Flexibility Act
Certification: The Secretary certifies that
this proposed regulatory action would
not have a significant economic impact
on a substantial number of small
entities. The U.S. Small Business
Administration (SBA) Size Standards
define ‘‘small entities’’ as for-profit or
nonprofit institutions with total annual
revenue below $7,000,000 or, if they are
institutions controlled by small
governmental jurisdictions (that are
comprised of cities, counties, towns,
townships, villages, school districts, or
special districts), with a population of
less than 50,000.
The small entities that this proposed
regulatory action would affect are LEAs,
including charter schools that operate as
LEAs under State law; institutions of
higher education; other public agencies;
private nonprofit organizations; freely
associated States and outlying areas;
Indian Tribes or Tribal organizations;
and for-profit organizations. We believe
that the costs imposed on an applicant
by the proposed priority would be
limited to paperwork burden related to
preparing an application and that the
benefits of the proposed priority would
outweigh any costs incurred by the
applicant.
Participation in the Technical
Assistance on State Data Collection
program is voluntary. For this reason,
VerDate Sep<11>2014
16:32 Mar 27, 2023
Jkt 259001
the proposed priority would impose no
burden on small entities unless they
applied for funding under the program.
We expect that in determining whether
to apply for Technical Assistance on
State Data Collection program funds, an
eligible entity would evaluate the
requirements of preparing an
application and any associated costs
and weigh them against the benefits
likely to be achieved by receiving a
Technical Assistance on State Data
Collection program grant. An eligible
entity probably would apply only if it
determines that the likely benefits
exceed the costs of preparing an
application.
We believe that the proposed priority
would not impose any additional
burden on a small entity applying for a
grant than the entity would face in the
absence of the proposed action. That is,
the length of the applications those
entities would submit in the absence of
the proposed regulatory action and the
time needed to prepare an application
would likely be the same.
This proposed regulatory action
would not have a significant economic
impact on a small entity once it receives
a grant because it would be able to meet
the costs of compliance using the funds
provided under this program. We invite
comments from eligible small entities as
to whether they believe this proposed
regulatory action would have a
significant economic impact on them
and, if so, request evidence to support
that belief.
Intergovernmental Review: This
program is subject to Executive Order
12372 and the regulations in 34 CFR
part 79. One of the objectives of the
Executive order is to foster an
intergovernmental partnership and a
strengthened federalism. The Executive
order relies on processes developed by
State and local governments for
coordination and review of proposed
Federal financial assistance.

I. Background
A. Ozone Air Pollution and Regulatory
Framework
Ground-level ozone pollution is
formed from the reaction of volatile
organic compounds (VOC) and oxides of
nitrogen (NOX) in the presence of
sunlight.1 These two pollutants, referred
to as ozone precursors, are emitted by
many types of sources, including onand off-road motor vehicles and
engines, power plants and industrial
facilities, and smaller area sources such
as lawn and garden equipment and
paints. Scientific evidence indicates that
adverse health effects occur following
exposure to elevated levels of ozone,
particularly in children and adults with
lung disease. Breathing air containing
ozone can reduce lung function and
inflame airways, which can increase
respiratory symptoms and aggravate
asthma or other lung diseases.2
Under section 109 of the CAA, the
EPA promulgates NAAQS for pervasive
air pollutants, such as ozone. The EPA
has previously promulgated NAAQS for
ozone in 1979 and 1997.3 In 2008, the
EPA revised and further strengthened
the ozone NAAQS by setting the
acceptable level of ozone in the ambient
air at 0.075 parts per million (ppm)
averaged over an 8-hour period.4
Although the EPA further tightened the
8-hour ozone NAAQS to 0.070 ppm in
2015, this action relates to the
requirements for the 2008 ozone
NAAQS.5
Following promulgation of a new or
revised NAAQS, the EPA is required
under CAA section 107(d) to designate
areas throughout the country as
attaining or not attaining the NAAQS.
The EPA classifies ozone nonattainment
areas under CAA section 181 according
to the severity of the ozone pollution
problem, with classifications ranging
from ‘‘Marginal’’ to ‘‘Extreme.’’ State
planning and emissions control
requirements for ozone are determined,
1 The State of California refers to reactive organic
gases (ROG) rather than VOC in some of its ozonerelated SIP submissions. As a practical matter, ROG
and VOC refer to the same set of chemical
constituents, and for simplicity, we refer to this set
of gases as VOC in this proposed rule.
2 For more information on ozone health effects,
see ‘‘Fact Sheet—2008 Final Revisions to the
National Ambient Air Quality Standards for
Ozone,’’ dated March 2008.
3 The ozone NAAQS promulgated in 1979 was
0.12 parts per million (ppm) averaged over a 1-hour
period. For information on the 1979 NAAQS, see
44 FR 8202 (February 8, 1979). The ozone NAAQS
promulgated in 1997 was 0.08 ppm averaged over
an 8-hour period. For information on the 1997
NAAQS, see 62 FR 38856 (July 18, 1997).

in part, by the nonattainment area’s
classification.
B. Sacramento Metro Nonattainment
Area
The EPA designated the Sacramento
Metro area as nonattainment for the
2008 8-hour ozone NAAQS on May 21,
2012, and classified the area as ‘‘Severe
15.’’ 6 The Sacramento Metro area
consists of Sacramento and Yolo
counties and portions of El Dorado,
Placer, Solano and Sutter counties.7 The
applicable attainment date for the 2008
ozone NAAQS for the Sacramento Metro
area is December 31, 2024.8
In California, the California Air
Resources Board (CARB) is the state
agency responsible for the adoption and
submission to the EPA of California SIP
submissions, and it has broad authority
to establish emissions standards and
other requirements for mobile sources.
Under California law, local and regional
air pollution control districts in
California are responsible for the
regulation of stationary sources and are
generally responsible for the
development of regional air quality
plans. In the Sacramento Metro area, the
El Dorado County Air Quality
Management District (EDCAQMD), the
Feather River Air Quality Management
District (FRAQMD), the Placer County
Air Pollution Control District
(PCAPCD), the Sacramento Metropolitan
Air Quality Management District
(SMAQMD), and the Yolo-Solano Air
Quality Management District
(YSAQMD) (collectively, ‘‘Districts’’)
develop and adopt air quality
management plans to address CAA
planning requirements applicable to the
region. The Districts then submit such
plans to CARB for adoption and
submission to the EPA as proposed
revisions to the California SIP.
C. State Implementation Plan Revisions
and Previous EPA Rulemaking
Under the CAA, after the EPA
designates areas as nonattainment for a
NAAQS, states with nonattainment
areas are required to submit SIP
revisions. With respect to areas
designated as nonattainment, states
must implement the 2008 8-hour ozone
NAAQS under Title 1, part D of the
6 77 FR 30088. ‘‘Severe-15’’ signifies a Severe area
that is required to attain the ozone standards within
15 years under CAA section 181(a)(1).
7 For a precise description of the geographic
boundaries of the Sacramento Metro area for the
2008 ozone standards, see 40 CFR 81.305.
Specifically included portions are the eastern
portion of Solano County, the western portions of
Placer and El Dorado counties outside of the Lake
Tahoe Air Basin, and the southern portion of Sutter
County.

Federal Register / Vol. 88, No. 59 / Tuesday, March 28, 2023 / Proposed Rules
CAA, which includes section 172
(‘‘Nonattainment plan provisions in
general’’) and sections 181–185 of
subpart 2 (‘‘Additional provisions for
ozone nonattainment areas’’). To assist
states in developing effective plans to
address ozone nonattainment problems,
in 2015, the EPA issued a SIP
Requirements Rule (SRR) for the 2008
8-hour ozone NAAQS (‘‘2008 Ozone
SRR’’) that addressed implementation of
the 2008 standards, including
attainment dates, requirements for
emissions inventories, attainment and
RFP demonstrations, as well as the
transition from the 1997 8-hour ozone
NAAQS to the 2008 8-hour ozone
NAAQS and associated anti-backsliding
requirements.9 The 2008 Ozone SRR is
codified at 40 CFR part 51, subpart AA.
On December 18, 2017, CARB
submitted the ‘‘Sacramento Regional
2008 NAAQS 8-Hour Ozone Attainment
and Reasonable Further Progress Plan’’
(‘‘2017 Sacramento Regional Ozone
Plan’’) to the EPA as a revision to the
California SIP.10 The 2017 Sacramento
Regional Ozone Plan addresses the
nonattainment area requirements for the
Sacramento Metro area concerning the
2008 ozone NAAQS, including the
contingency measures element. On
December 11, 2018, CARB submitted the
‘‘2018 Updates to the California State
Implementation Plan’’ (‘‘2018 SIP
Update’’).11 The 2018 SIP Update
provides updates to prior SIP submittals
for eight California nonattainment areas,
including information to support the

2017 Sacramento Regional Ozone Plan

this case, the court rejected the EPA’s longstanding
interpretation of CAA section 172(c)(9) as allowing
for early implementation of contingency measures.
The court concluded that a contingency measure
must take effect at the time the area fails to make
RFP or attain by the applicable attainment date, not
before. See also Sierra Club v. EPA, 985 F.3d 1055

In 2020, CARB and the Districts
committed to supplement these
contingency measures by adopting and
submitting additional contingency
measures that would be triggered upon
the area’s failure to attain or to meet
RFP. In a letter dated May 26, 2020, the
Districts committed to amend their
respective architectural coatings rules,13
and the SMAQMD committed to adopt
a new rule for reducing VOC emissions
from liquified petroleum gas transfer
and dispensing, commensurate with
South Coast Air Quality Management
District Rule 1177.14 CARB forwarded
the Districts’ May 26, 2020 letter to the
EPA on July 7, 2020, accompanied by a
letter committing to submit amended
rules to the EPA as a revision to the
California SIP within 12 months of a
final conditional approval of the
contingency measures element.15
On October 29, 2020, the EPA
proposed to approve the 2017
Sacramento Regional Ozone Plan and
the 2018 SIP Update as meeting the
emissions inventory, attainment
demonstration, reasonable further
progress, reasonably available control
measures, and motor vehicle emissions
budgets requirements for the 2008 ozone
NAAQS for the Sacramento Metro
nonattainment area.16 In that same
proposed rule, we proposed to
conditionally approve the contingency
measures element of these submittals,
based on the commitments by the
Districts and CARB to submit the new
and amended district rules to the EPA
within 12 months of a final conditional
approval of the contingency measures
element for the Sacramento Metro
relate to the Sacramento Metro nonattainment area
for the 2008 ozone NAAQS, see 85 FR 68509,
68512.
13 Specifically, the Districts committed to amend
their respective architectural coating rules to be
consistent with the CARB Architectural Coatings
Suggested Control Measure (SCM), as adopted on
May 21, 2019. This would include lowering the
VOC limits for several coating categories, deleting
the coating categories for non-flats, stains, floor, and
some other specialty coatings, and establishing new
VOC content limits for colorants.

area.17 On August 26, 2021, the Ninth
Circuit issued a decision in Association
of Irritated Residents v. U.S.
Environmental Protection Agency 18
(‘‘AIR v. EPA’’) which remanded the
EPA’s conditional approval of
contingency measures for another
California nonattainment area.
On October 22, 2021, we finalized our
approval of the 2017 Sacramento
Regional Ozone Plan and the 2018 SIP
Update with respect to the emissions
inventory, attainment demonstration,
RFP, reasonably available control
measures, and motor vehicle emissions
budgets requirements.19 Based on the
Ninth Circuit’s decision in AIR v. EPA,
we did not finalize our proposed
conditional approval of the contingency
measures element at that time.20
Because the EPA did not finalize our
conditional approval of the contingency
measures element, the 12-month period
during which CARB and the Districts
committed to submit supplemental
contingency measures never
commenced, and CARB and the
Districts have not adopted or submitted
the rules and revisions identified in
their commitment letters.
This proposed action replaces our
earlier proposed conditional approval of
the contingency measures element.
II. Evaluation
A. Procedural Requirements for
Adoption and Submission of SIP
Revisions
CAA sections 110(a) and 110(l)
require a state to provide reasonable
public notice and opportunity for public
hearing prior to the adoption and
submission of a SIP or SIP revision. To
meet this requirement, every SIP
submission should include evidence
that adequate public notice was given
and an opportunity for a public hearing
was provided consistent with the EPA’s
implementing regulations in 40 CFR
51.102. The EPA previously determined
that the Districts and CARB have
fulfilled the applicable requirements for
public notice and public hearing for the
2017 Sacramento Regional Ozone Plan
and 2018 SIP Update.21

B. Evaluation for Compliance With
Clean Air Act Contingency Measures
Requirements
Under the CAA, ozone nonattainment
areas classified under subpart 2 as
‘‘Serious’’ or above must include in
their SIPs contingency measures
consistent with sections 172(c)(9) and
182(c)(9). CAA section 172(c)(9)
requires states with nonattainment areas
to provide for the implementation of
specific measures to be undertaken if
the area fails to make RFP or to attain
the NAAQS by the applicable
attainment date. Such measures must be
included in the SIP as contingency
measures to take effect in any such case
without further action by the state or the
EPA. Section 182(c)(9) requires states to
provide contingency measures in the
event that an ozone nonattainment area
fails to meet any applicable RFP
milestone.
Contingency measures are additional
controls or measures to be implemented
in the event an area fails to make RFP
or to attain the NAAQS by the
attainment date. Contingency measures
must be designed so as to be
implemented prospectively; alreadyimplemented control measures may not
serve as contingency measures even if
they provide emissions reductions
beyond those needed for any other CAA
purpose.22 The SIP should contain
trigger mechanisms for the contingency
measures, specify a schedule for
implementation, and indicate that the
measure will be implemented without
significant further action by the state or
the EPA.23
Neither the CAA nor the EPA’s
implementing regulations establish a
specific amount of emissions reductions
that implementation of contingency
measures must achieve, but the 2008
Ozone SRR reiterates the EPA’s
guidance recommendation that
contingency measures should provide
for emissions reductions approximately
equivalent to one year’s worth of RFP,
thus amounting to reductions of three
percent of the baseline emissions
inventory for the nonattainment area.24
In AIR v. EPA, the Ninth Circuit
remanded the EPA’s approval of ozone
contingency measures for the San
Joaquin Valley and held that, under the
EPA’s existing guidance, the surplus
emissions reductions from alreadyimplemented measures cannot be relied
22 See Bahr v. EPA, 836 F.3d 1218, 1235–1237
(9th Cir. 2016) (‘‘Bahr’’).
23 For more information about the contingency
measures requirements see the 1997 Ozone Phase
2 Implementation Rule at 70 FR 71612 (November
29, 2005) and the 2008 Ozone SRR at 80 FR 12264,

upon to justify the approval of a
contingency measure that would
achieve far less than one year’s worth of
RFP as sufficient by itself to meet the
contingency measures requirements of
CAA sections 172(c)(9) and 182(c)(9) for
the nonattainment area.25
The Districts and CARB had largely
prepared the 2017 Sacramento Regional
Ozone Plan prior to the Bahr decision;
therefore, the plan relies solely upon
surplus emissions reductions from
already implemented control measures
in the RFP milestone years to
demonstrate compliance with the RFP
milestone contingency measures
requirements of CAA sections 172(c)(9)
and 182(c)(9).26 The plan also
demonstrates compliance with the
attainment contingency measures
requirements using surplus emissions
reductions (in the year after the
attainment year).27
In the 2018 SIP Update, CARB revised
the RFP demonstration for the 2008
ozone NAAQS for the Sacramento Metro
area and recalculated the extent of
surplus emission reductions in the
milestone years.28 Consistent with the
Bahr decision, the 2018 SIP Update does
not rely on the surplus or incremental
emissions reductions from alreadyimplemented measures to comply with
the contingency measures requirements
of sections 172(c)(9) and 182(c)(9) but
instead documents the extent to which
future baseline emissions from such
measures would provide surplus
emissions reductions beyond those
required to meet applicable contingency
measures requirements, to provide
context for determining the magnitude
of the emissions reductions needed from
prospective-acting, to-be-triggered
contingency measures.29
As noted in Section I.C of this notice,
the EPA previously proposed a
conditional approval of the Districts’
contingency measures, based upon
commitments by the Districts and CARB
to adopt and submit additional
contingency measure provisions in
District rules within 12 months of the
final conditional approval. Since the

EPA did not finalize the conditional
approval, the Districts and CARB did
not submit the additional contingency
measure provisions. Thus, the relevant
submittals before us are limited to the
portions of the 2017 Sacramento
Regional Ozone Plan and 2018 SIP
Update that address the contingency
measures requirements for the
Sacramento Metro area.
As described above, these submittals
provide only an analysis of surplus
emissions, and do not include specific
measures to be triggered upon a failure
to attain or to meet an RFP milestone
that would achieve one year’s worth of
progress. This approach is inconsistent
with CAA sections 172(c)(9) and
182(c)(9), in light of the Ninth Circuit’s
decisions in Bahr and AIR, and
accordingly we are proposing to
disapprove these portions of the 2017
Sacramento Regional Ozone Plan and
2018 SIP Update as contingency
measures for the Sacramento Metro area
for the 2008 ozone NAAQS.
III. Proposed Action and Clean Air Act
Consequences
For the reasons given in this notice,
we are proposing to disapprove the 2017
Sacramento Regional Ozone Plan and
the 2018 SIP Update with respect to
CAA contingency measures
requirements under CAA section
172(c)(9) and 182(c)(9) for the
Sacramento Metro area for the 2008
ozone NAAQS.
If the EPA finalizes the proposed
disapproval of the contingency
measures element of the 2017
Sacramento Regional Ozone Plan, as
modified by the 2018 SIP Update, the
area would be eligible for a protective
finding under the transportation
conformity rule because these
submittals reflect adopted control
measures and contain enforceable
commitments that fully satisfy the
emissions reductions requirements for
RFP and attainment for the 2008 Ozone
NAAQS.30
30 40 CFR 93.120(a)(3). Without a protective
finding, the final disapproval would result in a
conformity freeze, under which only projects in the
first four years of the most recent conforming
Regional Transportation Plan (RTP) and
Transportation Improvement Programs (TIP) can
proceed. Generally, during a freeze, no new RTPs,
TIPs, or RTP/TIP amendments can be found to
conform until another control strategy
implementation plan revision fulfilling the same
CAA requirements is submitted, the EPA finds its
motor vehicle emissions budget(s) adequate
pursuant to 40 CFR 93.118 or approves the
submission, and conformity to the implementation
plan revision is determined. Under a protective
finding, the final disapproval of the contingency
measures element would not result in a
transportation conformity freeze in the Sacramento

Federal Register / Vol. 88, No. 59 / Tuesday, March 28, 2023 / Proposed Rules
Further, if we finalize this proposed
disapproval of the contingency
measures element, the EPA must
promulgate a federal implementation
plan (FIP) under section 110(c) unless
we approve subsequent SIP revisions
that correct the rule deficiencies within
24 months. In addition, under 40 CFR
52.35, the offset sanction in CAA
section 179(b)(2) will be imposed 18
months after the effective date of this
action, and the highway funding
sanction in CAA section 179(b)(1) six
months after the offset sanction is
imposed. A sanction will not be
imposed if the EPA determines that a
subsequent SIP submission corrects the
identified deficiencies before the
applicable deadline.
IV. Request for Public Comment
The EPA is soliciting public
comments on the issues discussed in
this document. We will accept
comments from the public on this
proposal for the next 30 days and will
consider comments before taking final
action.

A. Executive Order 12866, Regulatory
Planning and Review and Executive
Order 13563: Improving Regulation and
Regulatory Review
This proposed action is not a
significant regulatory action and was
therefore not submitted to the Office of
Management and Budget (OMB) for
review.

B. Paperwork Reduction Act
This proposed action does not impose
an information collection burden under
the provisions of the Paperwork
Reduction Act, 44 U.S.C. 3501 et seq.,
because this proposed SIP disapproval
under section 110 and subchapter I, part
D of the CAA will not in-and-of itself
create any new information collection
burdens, but simply disapproves certain
state requirements submitted for
inclusion into the SIP. Burden is
defined at 5 CFR 1320.3(b).
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA)
generally requires an agency to conduct
a regulatory flexibility analysis of any
rule subject to notice and comment
rulemaking requirements unless the
Metro ozone nonattainment area and the local
metropolitan planning organizations may continue
to make transportation conformity determinations.

agency certifies that the rule will not
have a significant economic impact on
a substantial number of small entities.
Small entities include small businesses,
small not-for-profit enterprises, and
small governmental jurisdictions. For
purposes of assessing the impacts of this
proposed rule on small entities, small
entity is defined as: (1) a small business
as defined by the Small Business
Administration’s (SBA) regulations at 13
CFR 121.201; (2) a small governmental
jurisdiction that is a government of a
city, county, town, school district, or
special district with a population of less
than 50,000; and (3) a small
organization that is any not-for-profit
enterprise which is independently
owned and operated and is not
dominant in its field.
After considering the economic
impacts of this proposed action on small
entities, I certify that this proposed
action will not have a significant impact
on a substantial number of small
entities. This proposed rule does not
impose any requirements or create
impacts on small entities. This proposed
SIP disapproval under section 110 and
subchapter I, part D of the CAA will not
in-and-of itself create any new
requirements but simply disapproves
certain state requirements submitted for
inclusion into the SIP. Accordingly, it
affords no opportunity for the EPA to
fashion for small entities less
burdensome compliance or reporting
requirements or timetables or
exemptions from all or part of the rule.
The fact that the CAA prescribes that
various consequences (e.g., higher offset
requirements) may or will result from
disapproval actions does not mean that
the EPA either can or must conduct a
regulatory flexibility analysis for this
proposed action. Therefore, this
proposed action will not have a
significant economic impact on a
substantial number of small entities.
D. Unfunded Mandates Reform Act
This proposed action contains no
Federal mandates under the provisions
of title II of the Unfunded Mandates
Reform Act of 1995 (UMRA), 2 U.S.C.
1531–1538 for state, local, or tribal
governments or the private sector. The
EPA has determined that the proposed
disapproval action does not include a
federal mandate that may result in
estimated costs of $100 million or more
to either state, local, or tribal
governments in the aggregate, or to the
private sector. This action proposes to
disapprove pre-existing requirements
under state or local law and imposes no
new requirements. Accordingly, no
additional costs to state, local, or tribal

governments, or to the private sector,
result from this proposed action.
E. Executive Order 13132, Federalism
Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999), requires the EPA to develop an
accountable process to ensure
‘‘meaningful and timely input by state
and local officials in the development of
regulatory policies that have federalism
implications.’’ ‘‘Policies that have
federalism implications’’ is defined in
the Executive Order to include
regulations that have ‘‘substantial direct
effects on the states, on the relationship
between the national government and
the states, or on the distribution of
power and responsibilities among the
various levels of government.’’ This
proposed action does not have
federalism implications. It will not have
substantial direct effects on the states,
on the relationship between the national
government and the states, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, because it
merely disapproves certain state
requirements for inclusion into the SIP
and does not alter the relationship or
the distribution of power and
responsibilities established in the CAA.
Thus, Executive Order 13132 does not
apply to this proposed action.
F. Executive Order 13175, Coordination
With Indian Tribal Governments
This proposed action does not have
tribal implications, as specified in
Executive Order 13175 (65 FR 67249,
November 9, 2000), because the SIP that
the EPA is proposing to disapprove
would not 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, and the EPA notes that it
will not impose substantial direct costs
on tribal governments or preempt tribal
law. Thus, Executive Order 13175 does
not apply to this proposed action.
G. Executive Order 13045, Protection of
Children From Environmental Health
Risks and Safety Risks
The EPA interprets Executive Order
13045 (62 FR 19885, April 23, 1997) as
applying only to those regulatory
actions that concern health or safety
risks, such that the analysis required
under section 5–501 of the Executive
Order has the potential to influence the
regulation. This proposed action is not
subject to Executive Order 13045
because it is not an economically
significant regulatory action based on
health or safety risks subject to

Federal Register / Vol. 88, No. 59 / Tuesday, March 28, 2023 / Proposed Rules
Executive Order 13045 (62 FR 19885,
April 23, 1997). This proposed SIP
disapproval under section 110 and
subchapter I, part D of the CAA will not
in-and-of itself create any new
regulations but simply disapproves
certain state requirements submitted for
inclusion into the SIP.
H. Executive Order 13211, Actions That
Significantly Affect Energy Supply,
Distribution, or Use
This proposed action is not subject to
Executive Order 13211 (66 FR 28355,
May 22, 2001) because it is not a
significant regulatory action under
Executive Order 12866.

Technology Transfer and Advancement
Act of 1995 (‘‘NTTAA’’), Public Law
104–113, 12(d) (15 U.S.C. 272 note)
directs the EPA to use voluntary
consensus standards in its regulatory
activities unless to do so would be
inconsistent with applicable law or
otherwise impractical. Voluntary
consensus standards are technical
standards (e.g., materials specifications,
test methods, sampling procedures, and
business practices) that are developed or
adopted by voluntary consensus
standards bodies. NTTAA directs the
EPA to provide Congress, through OMB,
explanations when the Agency decides
not to use available and applicable
voluntary consensus standards. The
EPA believes that this proposed action
is not subject to requirements of Section

12(d) of NTTAA because application of
those requirements would be
inconsistent with the CAA.
J. Executive Order 12898: Federal
Actions To Address Environmental
Justice in Minority Populations and
Low-Income Population
Executive Order 12898 (Federal
Actions To Address Environmental
Justice in Minority Populations and
Low-Income Populations, 59 FR 7629,
February 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. EPA defines
environmental justice 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.’’ 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.’’
Under the CAA, the Administrator is
required to approve a SIP submission
that complies with the provisions of the
Act and applicable federal regulations.

Thus, in reviewing SIP submissions, the
EPA’s role is to review state choices,
and approve those choices if they meet
the minimum criteria of the Act.
Accordingly, this action proposes to
disapprove state submittals as not
meeting federal requirements, and does
not impose any additional requirements
beyond those imposed by state law.
Neither CARB nor the Districts
evaluated environmental justice
considerations as part of these SIP
submittals; the CAA and applicable
implementing regulations neither
prohibit nor require such an evaluation.
EPA did not perform an environmental
justice analysis and did not consider
environmental justice in this action.
Consideration of environmental justice
is not required as part of this action, and
there is no information in the record
inconsistent with the stated goal of
Executive Order 12898 of achieving
environmental justice for people of
color, low-income populations, and
Indigenous peoples.

Disapproval of Clean Air Plans; Sacramento Metro, California;
Contingency Measures for 2008 Ozone Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
disapprove under the Clean Air Act (CAA or ``Act'') state
implementation plan (SIP) submissions from the State of California that
address contingency measures requirements for the 2008 ozone national
ambient air quality standards (NAAQS or ``standards'') in the
Sacramento Metro, California ozone nonattainment area. The SIP
revisions include the portions of the following documents that address
the contingency measures requirements: the ``Sacramento Regional 2008
NAAQS 8-hour Ozone Attainment and Reasonable Further Progress Plan,''
submitted in 2017 (``2017 Sacramento Regional Ozone Plan''), and the
Sacramento Metro portion of the ``2018 Updates to the California State
Implementation Plan'' (``2018 SIP Update''). The EPA is proposing this
disapproval because the SIP revisions do not provide for contingency
[[Page 18287]]
measures that would be triggered if the area fails to attain the NAAQS
or make reasonable further progress (RFP).
DATES: Written comments must arrive on or before April 27, 2023.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R09-
OAR-2020-0425 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
Regulations.gov. The EPA may publish any comment received to its public
docket. Do not submit electronically any information you consider to be
Confidential Business Information (CBI) or other information whose
disclosure is restricted by statute. Multimedia submissions (audio,
video, etc.) must be accompanied by a written comment. The written
comment is considered the official comment and should include
discussion of all points you wish to make. The EPA will generally not
consider comments or comment contents located outside of the primary
submission (i.e., on the web, cloud, or other file sharing system). For
additional submission methods, please contact the person identified in

I. Background
A. Ozone Air Pollution and Regulatory Framework
Ground-level ozone pollution is formed from the reaction of
volatile organic compounds (VOC) and oxides of nitrogen
(NOX) in the presence of sunlight.\1\ These two pollutants,
referred to as ozone precursors, are emitted by many types of sources,
including on- and off-road motor vehicles and engines, power plants and
industrial facilities, and smaller area sources such as lawn and garden
equipment and paints. Scientific evidence indicates that adverse health
effects occur following exposure to elevated levels of ozone,
particularly in children and adults with lung disease. Breathing air
containing ozone can reduce lung function and inflame airways, which
can increase respiratory symptoms and aggravate asthma or other lung
diseases.\2\
---------------------------------------------------------------------------
\1\ The State of California refers to reactive organic gases
(ROG) rather than VOC in some of its ozone-related SIP submissions.
As a practical matter, ROG and VOC refer to the same set of chemical
constituents, and for simplicity, we refer to this set of gases as
VOC in this proposed rule.
\2\ For more information on ozone health effects, see ``Fact
Sheet--2008 Final Revisions to the National Ambient Air Quality
Standards for Ozone,'' dated March 2008.
---------------------------------------------------------------------------
Under section 109 of the CAA, the EPA promulgates NAAQS for
pervasive air pollutants, such as ozone. The EPA has previously
promulgated NAAQS for ozone in 1979 and 1997.\3\ In 2008, the EPA
revised and further strengthened the ozone NAAQS by setting the
acceptable level of ozone in the ambient air at 0.075 parts per million
(ppm) averaged over an 8-hour period.\4\ Although the EPA further
tightened the 8-hour ozone NAAQS to 0.070 ppm in 2015, this action
relates to the requirements for the 2008 ozone NAAQS.\5\
---------------------------------------------------------------------------
\3\ The ozone NAAQS promulgated in 1979 was 0.12 parts per
million (ppm) averaged over a 1-hour period. For information on the
1979 NAAQS, see 44 FR 8202 (February 8, 1979). The ozone NAAQS
promulgated in 1997 was 0.08 ppm averaged over an 8-hour period. For
information on the 1997 NAAQS, see 62 FR 38856 (July 18, 1997).
\4\ 73 FR 16436 (March 27, 2008).
\5\ Information on the 2015 ozone NAAQS is available at 80 FR
65292 (October 26, 2015).
---------------------------------------------------------------------------
Following promulgation of a new or revised NAAQS, the EPA is
required under CAA section 107(d) to designate areas throughout the
country as attaining or not attaining the NAAQS. The EPA classifies
ozone nonattainment areas under CAA section 181 according to the
severity of the ozone pollution problem, with classifications ranging
from ``Marginal'' to ``Extreme.'' State planning and emissions control
requirements for ozone are determined, in part, by the nonattainment
area's classification.
B. Sacramento Metro Nonattainment Area
The EPA designated the Sacramento Metro area as nonattainment for
the 2008 8-hour ozone NAAQS on May 21, 2012, and classified the area as
``Severe 15.'' \6\ The Sacramento Metro area consists of Sacramento and
Yolo counties and portions of El Dorado, Placer, Solano and Sutter
counties.\7\ The applicable attainment date for the 2008 ozone NAAQS
for the Sacramento Metro area is December 31, 2024.\8\
---------------------------------------------------------------------------
\6\ 77 FR 30088. ``Severe-15'' signifies a Severe area that is
required to attain the ozone standards within 15 years under CAA
section 181(a)(1).
\7\ For a precise description of the geographic boundaries of
the Sacramento Metro area for the 2008 ozone standards, see 40 CFR
81.305. Specifically included portions are the eastern portion of
Solano County, the western portions of Placer and El Dorado counties
outside of the Lake Tahoe Air Basin, and the southern portion of
Sutter County.
\8\ 85 FR 68509, 68510 (October 29, 2020).
---------------------------------------------------------------------------
In California, the California Air Resources Board (CARB) is the
state agency responsible for the adoption and submission to the EPA of
California SIP submissions, and it has broad authority to establish
emissions standards and other requirements for mobile sources. Under
California law, local and regional air pollution control districts in
California are responsible for the regulation of stationary sources and
are generally responsible for the development of regional air quality
plans. In the Sacramento Metro area, the El Dorado County Air Quality
Management District (EDCAQMD), the Feather River Air Quality Management
District (FRAQMD), the Placer County Air Pollution Control District
(PCAPCD), the Sacramento Metropolitan Air Quality Management District
(SMAQMD), and the Yolo-Solano Air Quality Management District (YSAQMD)
(collectively, ``Districts'') develop and adopt air quality management
plans to address CAA planning requirements applicable to the region.
The Districts then submit such plans to CARB for adoption and
submission to the EPA as proposed revisions to the California SIP.
C. State Implementation Plan Revisions and Previous EPA Rulemaking
Under the CAA, after the EPA designates areas as nonattainment for
a NAAQS, states with nonattainment areas are required to submit SIP
revisions. With respect to areas designated as nonattainment, states
must implement the 2008 8-hour ozone NAAQS under Title 1, part D of the
[[Page 18288]]
CAA, which includes section 172 (``Nonattainment plan provisions in
general'') and sections 181-185 of subpart 2 (``Additional provisions
for ozone nonattainment areas''). To assist states in developing
effective plans to address ozone nonattainment problems, in 2015, the
EPA issued a SIP Requirements Rule (SRR) for the 2008 8-hour ozone
NAAQS (``2008 Ozone SRR'') that addressed implementation of the 2008
standards, including attainment dates, requirements for emissions
inventories, attainment and RFP demonstrations, as well as the
transition from the 1997 8-hour ozone NAAQS to the 2008 8-hour ozone
NAAQS and associated anti-backsliding requirements.\9\ The 2008 Ozone
SRR is codified at 40 CFR part 51, subpart AA.
---------------------------------------------------------------------------
\9\ 80 FR 12264 (March 6, 2015).
---------------------------------------------------------------------------
On December 18, 2017, CARB submitted the ``Sacramento Regional 2008
NAAQS 8-Hour Ozone Attainment and Reasonable Further Progress Plan''
(``2017 Sacramento Regional Ozone Plan'') to the EPA as a revision to
the California SIP.\10\ The 2017 Sacramento Regional Ozone Plan
addresses the nonattainment area requirements for the Sacramento Metro
area concerning the 2008 ozone NAAQS, including the contingency
measures element. On December 11, 2018, CARB submitted the ``2018
Updates to the California State Implementation Plan'' (``2018 SIP
Update'').\11\ The 2018 SIP Update provides updates to prior SIP
submittals for eight California nonattainment areas, including
information to support the contingency measures element of the 2017
Sacramento Regional Ozone Plan in the wake of the decision by the U.S.
Court of Appeals for the Ninth Circuit (``Ninth Circuit'') in Bahr v.
EPA.\12\
---------------------------------------------------------------------------
\10\ Letter dated December 18, 2017, from Richard Corey,
Executive Officer, CARB, to Alexis Strauss, Acting Regional
Administrator, EPA Region IX.
\11\ Letter dated December 5, 2018, from Richard Corey,
Executive Officer, CARB, to Mike Stoker, Regional Administrator, EPA
Region IX (submitted electronically December 11, 2018). Our previous
proposed action at 85 FR 68509 and final action at 86 FR 58581
misidentified the date of the submittal of the 2018 SIP Update as
December 5, 2018. While the letter accompanying the submittal is
dated December 5, 2018, the EPA received the submittal
electronically on December 11, 2018. For more information, see the
eSIPs Application State Implementation Plan Summary Page in the
docket for this rulemaking. CARB adopted the 2018 SIP Update on
October 25, 2018.
\12\ Bahr v. EPA, 836 F.3d 1218 (9th Cir. 2016). In this case,
the court rejected the EPA's longstanding interpretation of CAA
section 172(c)(9) as allowing for early implementation of
contingency measures. The court concluded that a contingency measure
must take effect at the time the area fails to make RFP or attain by
the applicable attainment date, not before. See also Sierra Club v.
EPA, 985 F.3d 1055 (D.C. Cir. 2021), reaching a similar decision.
For a more complete description of the 2017 Sacramento Regional
Ozone Plan and 2018 SIP Update as they relate to the Sacramento
Metro nonattainment area for the 2008 ozone NAAQS, see 85 FR 68509,
68512.
---------------------------------------------------------------------------
In 2020, CARB and the Districts committed to supplement these
contingency measures by adopting and submitting additional contingency
measures that would be triggered upon the area's failure to attain or
to meet RFP. In a letter dated May 26, 2020, the Districts committed to
amend their respective architectural coatings rules,\13\ and the SMAQMD
committed to adopt a new rule for reducing VOC emissions from liquified
petroleum gas transfer and dispensing, commensurate with South Coast
Air Quality Management District Rule 1177.\14\ CARB forwarded the
Districts' May 26, 2020 letter to the EPA on July 7, 2020, accompanied
by a letter committing to submit amended rules to the EPA as a revision
to the California SIP within 12 months of a final conditional approval
of the contingency measures element.\15\
---------------------------------------------------------------------------
\13\ Specifically, the Districts committed to amend their
respective architectural coating rules to be consistent with the
CARB Architectural Coatings Suggested Control Measure (SCM), as
adopted on May 21, 2019. This would include lowering the VOC limits
for several coating categories, deleting the coating categories for
non-flats, stains, floor, and some other specialty coatings, and
establishing new VOC content limits for colorants.

Executive Officer, CARB, Subject: ``Commitments from the Sacramento
Federal Nonattainment Area Districts to Adopt and/or Amend Rules as
Contingency Measures for the Sacramento Regional 2008 NAAQS 8-Hour
Ozone Attainment and Reasonable Further Progress Plan.''
\15\ Letter dated July 7, 2020, from Richard W. Corey, Executive
Officer, CARB, to John Busterud, Regional Administrator, EPA Region
IX.
---------------------------------------------------------------------------
On October 29, 2020, the EPA proposed to approve the 2017
Sacramento Regional Ozone Plan and the 2018 SIP Update as meeting the
emissions inventory, attainment demonstration, reasonable further
progress, reasonably available control measures, and motor vehicle
emissions budgets requirements for the 2008 ozone NAAQS for the
Sacramento Metro nonattainment area.\16\ In that same proposed rule, we
proposed to conditionally approve the contingency measures element of
these submittals, based on the commitments by the Districts and CARB to
submit the new and amended district rules to the EPA within 12 months
of a final conditional approval of the contingency measures element for
the Sacramento Metro area.\17\ On August 26, 2021, the Ninth Circuit
issued a decision in Association of Irritated Residents v. U.S.
Environmental Protection Agency \18\ (``AIR v. EPA'') which remanded
the EPA's conditional approval of contingency measures for another
California nonattainment area.
---------------------------------------------------------------------------
\16\ 85 FR 68509.
\17\ Id.
\18\ 10 F.4th 937 (9th Cir. 2021).
---------------------------------------------------------------------------
On October 22, 2021, we finalized our approval of the 2017
Sacramento Regional Ozone Plan and the 2018 SIP Update with respect to
the emissions inventory, attainment demonstration, RFP, reasonably
available control measures, and motor vehicle emissions budgets
requirements.\19\ Based on the Ninth Circuit's decision in AIR v. EPA,
we did not finalize our proposed conditional approval of the
contingency measures element at that time.\20\ Because the EPA did not
finalize our conditional approval of the contingency measures element,
the 12-month period during which CARB and the Districts committed to
submit supplemental contingency measures never commenced, and CARB and
the Districts have not adopted or submitted the rules and revisions
identified in their commitment letters.
---------------------------------------------------------------------------
\19\ 86 FR 58581.
\20\ See id. at 58590 (responding to comments on proposed
approval of contingency measures element submitted by Air Law for
All, Ltd. on behalf of Center for Biological Diversity and Center
for Environmental Health).
---------------------------------------------------------------------------
This proposed action replaces our earlier proposed conditional
approval of the contingency measures element.
II. Evaluation
A. Procedural Requirements for Adoption and Submission of SIP Revisions
CAA sections 110(a) and 110(l) require a state to provide
reasonable public notice and opportunity for public hearing prior to
the adoption and submission of a SIP or SIP revision. To meet this
requirement, every SIP submission should include evidence that adequate
public notice was given and an opportunity for a public hearing was
provided consistent with the EPA's implementing regulations in 40 CFR
51.102. The EPA previously determined that the Districts and CARB have
fulfilled the applicable requirements for public notice and public
hearing for the 2017 Sacramento Regional Ozone Plan and 2018 SIP
Update.\21\
---------------------------------------------------------------------------
\21\ 85 FR 68509, 68512; 86 FR 58581, 58582-83.
---------------------------------------------------------------------------
[[Page 18289]]
B. Evaluation for Compliance With Clean Air Act Contingency Measures
Requirements
Under the CAA, ozone nonattainment areas classified under subpart 2
as ``Serious'' or above must include in their SIPs contingency measures
consistent with sections 172(c)(9) and 182(c)(9). CAA section 172(c)(9)
requires states with nonattainment areas to provide for the
implementation of specific measures to be undertaken if the area fails
to make RFP or to attain the NAAQS by the applicable attainment date.
Such measures must be included in the SIP as contingency measures to
take effect in any such case without further action by the state or the
EPA. Section 182(c)(9) requires states to provide contingency measures
in the event that an ozone nonattainment area fails to meet any
applicable RFP milestone.
Contingency measures are additional controls or measures to be
implemented in the event an area fails to make RFP or to attain the
NAAQS by the attainment date. Contingency measures must be designed so
as to be implemented prospectively; already-implemented control
measures may not serve as contingency measures even if they provide
emissions reductions beyond those needed for any other CAA purpose.\22\
The SIP should contain trigger mechanisms for the contingency measures,
specify a schedule for implementation, and indicate that the measure
will be implemented without significant further action by the state or
the EPA.\23\
---------------------------------------------------------------------------
\22\ See Bahr v. EPA, 836 F.3d 1218, 1235-1237 (9th Cir. 2016)
(``Bahr'').
\23\ For more information about the contingency measures
requirements see the 1997 Ozone Phase 2 Implementation Rule at 70 FR
71612 (November 29, 2005) and the 2008 Ozone SRR at 80 FR 12264,
12285 (March 6, 2015).
---------------------------------------------------------------------------
Neither the CAA nor the EPA's implementing regulations establish a
specific amount of emissions reductions that implementation of
contingency measures must achieve, but the 2008 Ozone SRR reiterates
the EPA's guidance recommendation that contingency measures should
provide for emissions reductions approximately equivalent to one year's
worth of RFP, thus amounting to reductions of three percent of the
baseline emissions inventory for the nonattainment area.\24\ In AIR v.
EPA, the Ninth Circuit remanded the EPA's approval of ozone contingency
measures for the San Joaquin Valley and held that, under the EPA's
existing guidance, the surplus emissions reductions from already-
implemented measures cannot be relied upon to justify the approval of a
contingency measure that would achieve far less than one year's worth
of RFP as sufficient by itself to meet the contingency measures
requirements of CAA sections 172(c)(9) and 182(c)(9) for the
nonattainment area.\25\

---------------------------------------------------------------------------
The Districts and CARB had largely prepared the 2017 Sacramento
Regional Ozone Plan prior to the Bahr decision; therefore, the plan
relies solely upon surplus emissions reductions from already
implemented control measures in the RFP milestone years to demonstrate
compliance with the RFP milestone contingency measures requirements of
CAA sections 172(c)(9) and 182(c)(9).\26\ The plan also demonstrates
compliance with the attainment contingency measures requirements using
surplus emissions reductions (in the year after the attainment
year).\27\

and Reasonable Further Progress Plan,'' July 24, 2017, 12-1 to 12-6.

---------------------------------------------------------------------------
In the 2018 SIP Update, CARB revised the RFP demonstration for the
2008 ozone NAAQS for the Sacramento Metro area and recalculated the
extent of surplus emission reductions in the milestone years.\28\
Consistent with the Bahr decision, the 2018 SIP Update does not rely on
the surplus or incremental emissions reductions from already-
implemented measures to comply with the contingency measures
requirements of sections 172(c)(9) and 182(c)(9) but instead documents
the extent to which future baseline emissions from such measures would
provide surplus emissions reductions beyond those required to meet
applicable contingency measures requirements, to provide context for
determining the magnitude of the emissions reductions needed from
prospective-acting, to-be-triggered contingency measures.\29\
---------------------------------------------------------------------------
\28\ ``2018 Updates to the California State Implementation
Plan,'' October 25, 2018, 27-34.
\29\ The 2018 SIP Update identifies enhanced enforcement
activities intended to serve as contingency measure to be triggered
upon a failure to attain or meet RFP. See 2018 SIP Update, Chapter
X. However, CARB subsequently withdrew this measure from
consideration for inclusion in the Sacramento Metro portion of the
California SIP. See letter dated January 8, 2021, from Richard W.
Corey, Executive Officer, CARB, to John W. Busterud, Regional
Administrator, EPA Region IX.
---------------------------------------------------------------------------
As noted in Section I.C of this notice, the EPA previously proposed
a conditional approval of the Districts' contingency measures, based
upon commitments by the Districts and CARB to adopt and submit
additional contingency measure provisions in District rules within 12
months of the final conditional approval. Since the EPA did not
finalize the conditional approval, the Districts and CARB did not
submit the additional contingency measure provisions. Thus, the
relevant submittals before us are limited to the portions of the 2017
Sacramento Regional Ozone Plan and 2018 SIP Update that address the
contingency measures requirements for the Sacramento Metro area.
As described above, these submittals provide only an analysis of
surplus emissions, and do not include specific measures to be triggered
upon a failure to attain or to meet an RFP milestone that would achieve
one year's worth of progress. This approach is inconsistent with CAA
sections 172(c)(9) and 182(c)(9), in light of the Ninth Circuit's
decisions in Bahr and AIR, and accordingly we are proposing to
disapprove these portions of the 2017 Sacramento Regional Ozone Plan
and 2018 SIP Update as contingency measures for the Sacramento Metro
area for the 2008 ozone NAAQS.
III. Proposed Action and Clean Air Act Consequences
For the reasons given in this notice, we are proposing to
disapprove the 2017 Sacramento Regional Ozone Plan and the 2018 SIP
Update with respect to CAA contingency measures requirements under CAA
section 172(c)(9) and 182(c)(9) for the Sacramento Metro area for the
2008 ozone NAAQS.
If the EPA finalizes the proposed disapproval of the contingency
measures element of the 2017 Sacramento Regional Ozone Plan, as
modified by the 2018 SIP Update, the area would be eligible for a
protective finding under the transportation conformity rule because
these submittals reflect adopted control measures and contain
enforceable commitments that fully satisfy the emissions reductions
requirements for RFP and attainment for the 2008 Ozone NAAQS.\30\
---------------------------------------------------------------------------
\30\ 40 CFR 93.120(a)(3). Without a protective finding, the
final disapproval would result in a conformity freeze, under which
only projects in the first four years of the most recent conforming
Regional Transportation Plan (RTP) and Transportation Improvement
Programs (TIP) can proceed. Generally, during a freeze, no new RTPs,
TIPs, or RTP/TIP amendments can be found to conform until another
control strategy implementation plan revision fulfilling the same
CAA requirements is submitted, the EPA finds its motor vehicle
emissions budget(s) adequate pursuant to 40 CFR 93.118 or approves
the submission, and conformity to the implementation plan revision
is determined. Under a protective finding, the final disapproval of
the contingency measures element would not result in a
transportation conformity freeze in the Sacramento Metro ozone
nonattainment area and the local metropolitan planning organizations
may continue to make transportation conformity determinations.
---------------------------------------------------------------------------
[[Page 18290]]
Further, if we finalize this proposed disapproval of the
contingency measures element, the EPA must promulgate a federal
implementation plan (FIP) under section 110(c) unless we approve
subsequent SIP revisions that correct the rule deficiencies within 24
months. In addition, under 40 CFR 52.35, the offset sanction in CAA
section 179(b)(2) will be imposed 18 months after the effective date of
this action, and the highway funding sanction in CAA section 179(b)(1)
six months after the offset sanction is imposed. A sanction will not be
imposed if the EPA determines that a subsequent SIP submission corrects
the identified deficiencies before the applicable deadline.
IV. Request for Public Comment
The EPA is soliciting public comments on the issues discussed in
this document. We will accept comments from the public on this proposal
for the next 30 days and will consider comments before taking final
action.
V. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at https://www2.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866, Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This proposed action is not a significant regulatory action and was
therefore not submitted to the Office of Management and Budget (OMB)
for review.
B. Paperwork Reduction Act
This proposed action does not impose an information collection
burden under the provisions of the Paperwork Reduction Act, 44 U.S.C.
3501 et seq., because this proposed SIP disapproval under section 110
and subchapter I, part D of the CAA will not in-and-of itself create
any new information collection burdens, but simply disapproves certain
state requirements submitted for inclusion into the SIP. Burden is
defined at 5 CFR 1320.3(b).
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements unless the agency certifies
that the rule will not have a significant economic impact on a
substantial number of small entities. Small entities include small
businesses, small not-for-profit enterprises, and small governmental
jurisdictions. For purposes of assessing the impacts of this proposed
rule on small entities, small entity is defined as: (1) a small
business as defined by the Small Business Administration's (SBA)
regulations at 13 CFR 121.201; (2) a small governmental jurisdiction
that is a government of a city, county, town, school district, or
special district with a population of less than 50,000; and (3) a small
organization that is any not-for-profit enterprise which is
independently owned and operated and is not dominant in its field.
After considering the economic impacts of this proposed action on
small entities, I certify that this proposed action will not have a
significant impact on a substantial number of small entities. This
proposed rule does not impose any requirements or create impacts on
small entities. This proposed SIP disapproval under section 110 and
subchapter I, part D of the CAA will not in-and-of itself create any
new requirements but simply disapproves certain state requirements
submitted for inclusion into the SIP. Accordingly, it affords no
opportunity for the EPA to fashion for small entities less burdensome
compliance or reporting requirements or timetables or exemptions from
all or part of the rule. The fact that the CAA prescribes that various
consequences (e.g., higher offset requirements) may or will result from
disapproval actions does not mean that the EPA either can or must
conduct a regulatory flexibility analysis for this proposed action.
Therefore, this proposed action will not have a significant economic
impact on a substantial number of small entities.
D. Unfunded Mandates Reform Act
This proposed action contains no Federal mandates under the
provisions of title II of the Unfunded Mandates Reform Act of 1995
(UMRA), 2 U.S.C. 1531-1538 for state, local, or tribal governments or
the private sector. The EPA has determined that the proposed
disapproval action does not include a federal mandate that may result
in estimated costs of $100 million or more to either state, local, or
tribal governments in the aggregate, or to the private sector. This
action proposes to disapprove pre-existing requirements under state or
local law and imposes no new requirements. Accordingly, no additional
costs to state, local, or tribal governments, or to the private sector,
result from this proposed action.
E. Executive Order 13132, Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires the EPA to develop an accountable process to ensure
``meaningful and timely input by state and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the states, on the relationship between the national
government and the states, or on the distribution of power and
responsibilities among the various levels of government.'' This
proposed action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government, as
specified in Executive Order 13132, because it merely disapproves
certain state requirements for inclusion into the SIP and does not
alter the relationship or the distribution of power and
responsibilities established in the CAA. Thus, Executive Order 13132
does not apply to this proposed action.
F. Executive Order 13175, Coordination With Indian Tribal Governments
This proposed action does not have tribal implications, as
specified in Executive Order 13175 (65 FR 67249, November 9, 2000),
because the SIP that the EPA is proposing to disapprove would not 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, and the
EPA notes that it will not impose substantial direct costs on tribal
governments or preempt tribal law. Thus, Executive Order 13175 does not
apply to this proposed action.
G. Executive Order 13045, Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets Executive Order 13045 (62 FR 19885, April 23,
1997) as applying only to those regulatory actions that concern health
or safety risks, such that the analysis required under section 5-501 of
the Executive Order has the potential to influence the regulation. This
proposed action is not subject to Executive Order 13045 because it is
not an economically significant regulatory action based on health or
safety risks subject to
[[Page 18291]]
Executive Order 13045 (62 FR 19885, April 23, 1997). This proposed SIP
disapproval under section 110 and subchapter I, part D of the CAA will
not in-and-of itself create any new regulations but simply disapproves
certain state requirements submitted for inclusion into the SIP.
H. Executive Order 13211, Actions That Significantly Affect Energy
Supply, Distribution, or Use
This proposed action is not subject to Executive Order 13211 (66 FR
28355, May 22, 2001) because it is not a significant regulatory action
under Executive Order 12866.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note)
directs the EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. NTTAA directs the EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards. The EPA
believes that this proposed action is not subject to requirements of
Section 12(d) of NTTAA because application of those requirements would
be inconsistent with the CAA.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Population
Executive Order 12898 (Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
February 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.
EPA defines environmental justice 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.'' 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.''
Under the CAA, 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 review state choices,
and approve those choices if they meet the minimum criteria of the Act.
Accordingly, this action proposes to disapprove state submittals as not
meeting federal requirements, and does not impose any additional
requirements beyond those imposed by state law. Neither CARB nor the
Districts evaluated environmental justice considerations as part of
these SIP submittals; the CAA and applicable implementing regulations
neither prohibit nor require such an evaluation. EPA did not perform an
environmental justice analysis and did not consider environmental
justice in this action. Consideration of environmental justice is not
required as part of this action, and there is no information in the
record inconsistent with the stated goal of Executive Order 12898 of
achieving environmental justice for people of color, low-income
populations, and Indigenous peoples.
