I. Summary of the Proposed Actions
On July 8, 2024, the EPA proposed
two actions related to the CAA
requirements for the 1997 annual PM2.5
NAAQS in the San Joaquin Valley
Serious nonattainment area.
In the first action, under CAA section
110(k)(3), the EPA proposed to approve
through parallel processing the
‘‘Amendments to the 15 mg/m3 SIP
Revision and Agricultural Equipment
Incentive Measure for the 1997 PM2.5
Standard’’ (‘‘15 mg/m3 Plan
Amendments’’) as a revision to the
California SIP.1 The 15 mg/m3 Plan
Amendments seek to amend a SIPapproved measure, the ‘‘Accelerated
Turnover of Agricultural Equipment
Incentive Projects’’ (‘‘Valley Incentive
Measure’’), to include a quantification of
the emissions reductions for the year
2023 from existing agricultural
equipment projects from the California
Air Resources Board’s (CARB’s) Carl
Moyer Memorial Air Quality Standards
Attainment Program (‘‘Carl Moyer’’) and
CARB’s Funding Agricultural
Replacement Measures for Emission
Reductions (FARMER) program and
seek EPA approval of those emission
reductions for SIP credit. The 15 mg/m3
Plan Amendments also seek to revise
the aggregate tonnage commitment in
the attainment plan for the 1997 annual
PM2.5 NAAQS (i.e., the ‘‘Attainment
Plan Revision for the 1997 Annual PM2.5
Standard’’ (‘‘15 mg/m3 SIP Revision’’))
by replacing it with a commitment to
achieve the same reductions from the
Valley Incentive Measure. As part of the
EPA’s proposal to approve the 15 mg/m3
Plan Amendments, we proposed to
approve the State’s demonstration that
the Valley Incentive Measure has
achieved emissions reductions of 5.0
tons per day (tpd) of nitrogen oxides
(NOX) and 0.27 tpd of direct PM2.5 in the
year 2023, and proposed to credit the
reductions as a substitute measure to
meet the aggregate tonnage commitment
in the 15 mg/m3 SIP Revision.2
In the second action, based in part on
our proposal to approve the 15 mg/m3
Plan Amendments, the EPA proposed to
grant California’s request for a one-year
extension of the applicable attainment
date from December 31, 2023, to
December 31, 2024, for the 1997 annual
PM2.5 San Joaquin Valley, California,
nonattainment area.3 The proposed
action to extend the applicable
attainment date for this nonattainment
area was based on the EPA’s evaluation
of air quality monitoring data and
extension request submitted by the State
of California, and our determination that
the State has satisfied the two statutory
criteria for a one-year extension under
CAA section 172(a)(2)(C): The State has
complied with all requirements and
commitments pertaining to the area in
the applicable implementation plan,
and in accordance with guidance
published by the Administrator, no
more than the minimal number of
exceedances of the relevant national
ambient air quality standard has
occurred in the area in the year
preceding the Extension Year.
For details regarding the EPA’s
reasons for proposing to approve the 15
mg/m3 Plan Amendments and to grant
the one-year extension, please see the
July 8, 2024 proposal notices.4
On August 22, 2024, California
submitted the final version of the 15 mg/
m3 Plan Amendments to the EPA as a

revision to the California SIP.5 We have
reviewed this submittal and find that it
fulfills the SIP completeness criteria of
40 CFR part 51, Appendix V. The SIP
submission also includes evidence that
adequate public notice was given and
that an opportunity for a public hearing
was provided consistent with the EPA’s
implementing regulations in 40 CFR
51.102. Specifically, CARB provided
public notice and opportunity for public
comment prior to its July 25, 2024
public hearing on and adoption of the
15 mg/m3 Plan Amendments.6 The SIP
submission includes proof of
publication notices for the public
hearing and includes copies of the
written and oral comments received
during the State’s public review
processes and CARB’s responses
thereto.7 Therefore, we find that the 15
mg/m3 Plan Amendments meet the
procedural requirements for public
notice and hearing in CAA sections
110(a) and 110(l) and 40 CFR 51.102.

community organizations, in order of appearance in
the letter, are the Central California Asthma

23 The four sets of comments supporting our
proposal include those from the private citizen
commenter received August 7, 2024, those from the
Citizens Advisory Committee, those from CARB,
and those from SJVUAPCD.
24 The three sets of comments that are not
germane to our action include those from the
private citizen commenter received on June 28,
2024, those received from a private citizen
commenter on July 27, 2024, and those from the
university professor.
25 One of the comments titled ‘‘Comments on
‘Review of San Joaquin Valley 2024 Plan for the 12
mg/m3 Annual PM2.5 Standard’ by CARB, June 14,
2024’’ concerns PM2.5 concentrations in San Joaquin
Valley; however, the title of the comment and the
analysis therein indicates that it is directed at the
State’s attainment plan for the 2012 annual PM2.5
NAAQS. The comment presents evidence that
purports to show that the State’s attainment
modeling for the 2012 annual PM2.5 NAAQS is
flawed; however such modeling is not relevant to
this action that concerns whether the State has met
the requirements for a one-year extension of the
attainment date for the 1997 annual PM2.5 NAAQS.
Thus, the comment is not germane to this action
and does not necessitate any further response at this
time. The EPA will review the State’s attainment
plan for the 2012 annual PM2.5 NAAQS for
compliance with the requirements of the CAA and
the EPA’s regulations, and will determine,
following notice-and-comment rulemaking, whether
the submission satisfies all applicable CAA
requirements. We encourage the commenter to
resubmit these comments as appropriate during
such a future rulemaking.

Federal Register / Vol. 89, No. 223 / Tuesday, November 19, 2024 / Rules and Regulations
Citing PM2.5 design values for 2018–
2020, 2019–2021, and 2020–2022 of
17.6 mg/m3, 17.8 mg/m3, and 18.8 mg/m3,
CCAC claims that PM2.5 concentrations
have not improved and remain well
above the 15 mg/m3 level of the 1997
annual PM2.5 NAAQS. CCAC also states
that ‘‘EPA [has] correctly recognized the
environmental injustice San Joaquin
Valley residents endure’’ and
summarizes findings from the EPA’s
prior environmental justice (EJ) analyses
for the area.
Response 1: The EPA acknowledges
that there are communities with EJ
concerns in the San Joaquin Valley and
does not dispute the challenges
associated with attaining the 1997
annual PM2.5 NAAQS in this area. We
also acknowledge that the Demographic
Index analysis the EPA discussed in the
proposal to grant the extension of the
attainment date indicates that the
indices that reflect the area’s percent
minority and percent low-income
populations are above the national
averages for those indices.26
Nevertheless, the CAA provides states
the opportunity to request an extension
of the applicable attainment date for a
nonattainment area if they meet certain
statutory criteria, including that the area
met the air quality standard in question
in the year leading up to the applicable
attainment date.27
CCAC also expressed concern that
PM2.5 concentrations in the Valley have
not improved in recent years, and that
this pattern should weigh against the
extension of the attainment date. The
EPA must assess whether to grant the
attainment date extension in light of the
statutory criteria. We note that CCAC
relies on design values 28 to evaluate the
pace of improvement in the area.
However, design values, which reflect
the annual average over a three-year
period, are not the metric that EPA uses
to determine whether a state qualifies
for a one-year attainment date
extension. Rather, pursuant to section
172(a)(2)(C) of the Act, the EPA looks to
the monitor data in the year leading up
to the attainment date (i.e., in this case,
calendar year 2023) to assess an area’s
recent progress. As discussed in the
proposal to grant the one-year extension
of the attainment date, the EPA
reviewed 2023 annual mean
concentrations at each of the regulatory
monitoring sites in the San Joaquin
Valley and determined that such data
indicate that PM2.5 concentrations were

below the 15.0 mg/m3 level of the 1997
annual PM2.5 NAAQS.29
Moreover, 2023 annual mean
concentrations were lower than annual
mean concentrations in 2021 and 2022,
indicating an improvement in air
quality conditions in 2023 relative to
previous years.30 This is true even
without considering potential impacts
from any exceptional events during that
timeframe.31 32
The EPA notes that while this final
action extends the attainment date for
the San Joaquin Valley for the 1997
annual PM2.5 NAAQS to December 31,
2024, the area will remain classified as
Serious nonattainment for those
NAAQS and is not relieved of any
planning obligations under the CAA.
Following the December 31, 2024
attainment date, the State and the EPA
will assess whether the area has attained
the 1997 annual PM2.5 NAAQS. If the
area has met the NAAQS, the EPA will
make a determination that the area
attained by the attainment date. If the
area has not met the NAAQS, the State
may request a second one-year
extension if the area meets the CAA
requirements for such an extension. If
the State does not qualify for, or the
EPA denies a request for, a second oneyear extension under CAA section 172,
then the EPA will issue a finding of
failure to attain and the State will
become subject to additional CAA
requirements to achieve attainment of
the 1997 annual PM2.5 NAAQS in the
San Joaquin Valley area.
Comment 2.A: CCAC asserts that the
EPA does not have authority to grant a
one-year extension of the attainment
date for the San Joaquin Valley for the
1997 annual PM2.5 NAAQS under CAA
section 172(a)(2)(C). Specifically, CCAC
notes that subpart 4 of Part D of Title I

31 Exceptional Events are unusual or naturally
occurring events that can affect air quality but are
not reasonably controllable using techniques that
tribal, state or local air agencies may implement in
order to attain and maintain the NAAQS.
Exceptional events may include wildfires, high
wind dust events, prescribed fires, stratospheric
ozone intrusions, and volcanic and seismic
activities.
32 In the May 14, 2024, letter submitting
documentation to support the State’s request for an
attainment date extension, the District noted that
they and CARB ‘‘are evaluating potential
documentation to remove exceptional events
(including wildfire impacts) from the 2021–2023
period, as allowed under the CAA and EPA
policies.’’ Letter dated May 14, 2024, from Samir

Nonattainment Area.’’

of the Act provides for attainment date
extensions for PM2.5 nonattainment
areas under specific circumstances
under section 188, and thus section 188
controls the question of whether the
EPA can grant an attainment date
extension for a Serious PM2.5
nonattainment area that fails to attain by
the applicable attainment date. CCAC
asserts that attainment date extensions
for Serious nonattainment areas are
addressed by CAA section 188(e), that
California did not request such an
extension, and that therefore such
extension is not available at this time to
the San Joaquin Valley for the 1997
annual PM2.5 NAAQS.
Response 2.A: The EPA disagrees
with the commenter that the attainment
date extension provisions under CAA
section 188 control the present action.
As CCAC accurately explains, the
EPA reclassified the San Joaquin Valley
as Serious nonattainment for the 1997
annual PM2.5 NAAQS effective May 7,
2015.33 The following year, the EPA
found that the San Joaquin Valley failed
to attain by the applicable Serious
attainment date and that sections 179(d)
and 189(d) of the CAA governed all
subsequent plan requirements and
attainment deadlines.34
Crucially, following a finding of
failure to attain for a Serious PM2.5
nonattainment area, CAA section 189(d)
does not provide for a specific
attainment date, and it instead requires:
[T]he State in which such area is located
shall, after notice and opportunity for public
comment, submit within 12 months after the
applicable attainment date, plan revisions
which provide for attainment of the [PM2.5]
air quality standard and, from the date of
such submission until attainment for an
annual reduction in [PM2.5] or [PM2.5]
precursor emissions within the area of not
less than 5 percent of the amount of such
emissions as reported in the most recent
inventory prepared for such area.35
With respect to the new applicable
attainment date for an area governed by
CAA section 189(d), the EPA explained
in the PM2.5 SIP Requirements Rule 36
that:
[T]he final rule includes the overarching
requirement for a Serious area that failed to
attain by the previous attainment date to
establish a new date for attaining the
standard as expeditiously as practicable.
However, neither CAA section 189(d) nor
other sections in subpart 4 explicitly
establish or provide the authority to establish
a new attainment date for the area. Therefore,
once an area is beyond the attainment dates
that Congress specified in subpart 4 for the

PM10 NAAQS, the EPA must look to other
provisions of part D of the CAA to provide
authority for a new attainment date. Sections
179(d)(3) and 172(a)(2) of the CAA provide
generally applicable attainment dates that fill
the gap in the statute left for areas subject to
the requirements of CAA section 189(d).
Thus, for a PM2.5 nonattainment area subject
to CAA section 189(d) requirements, the EPA
must establish a new attainment date
according to the provisions of CAA section
179(d)(3) and 172(a)(2). The EPA has
followed this same approach in the past for
PM10 nonattainment areas governed by
subpart 4 nonattainment requirements.37
Thus, subpart 4 controls the
requirements for an attainment plan
under CAA section 189(d); however,
after a Serious PM2.5 nonattainment area
fails to attain by the attainment date, the
applicable attainment date for a Serious
PM2.5 nonattainment area subject to the
requirements of CAA section 189(d) is
controlled by the generally applicable
provisions in subpart 1 of part D, CAA
section 172.
Contrary to the commenter’s
assertion, section 172 explicitly
provides for the extension that the EPA
is finalizing as part of this action. The
commenter cites CAA section
172(a)(2)(D), which states, ‘‘[t]his
paragraph shall not apply with respect
to nonattainment areas for which
attainment dates are specifically
provided under other provisions of this
part.’’ But as explained above, the
attainment date for an attainment plan
required under CAA section 189(d) is
not specifically provided under the
provisions in subpart 4, which is why
the EPA relied on section 172 in setting
the December 31, 2023 attainment date
for the San Joaquin Valley.38
Because CAA section 172 controls for
purposes of setting an attainment date
for a plan required under CAA section
189(d), it is logical and reasonable that
the generally applicable provisions in
section 172 would control an extension
of that attainment date in the absence of
any specific authority in subpart 4 for
such extensions.
Comment 2.B: CCAC claims that the
EPA evaluates the State’s request for an
attainment date extension pursuant to
EPA guidance on the implementation of
CAA section 188(d), which concerns
attainment date extensions for Moderate
PM2.5 nonattainment areas, and asserts
that the EPA does not have authority to
apply such provisions to a Serious PM2.5
nonattainment area.
Response 2.B: The EPA is not granting
the extension pursuant to section 188(d)
of the Act. Rather, because section
172(a)(2)(C) does not have PM-specific

provisions and because the EPA has not
issued guidance on how to implement
the provisions of section 172(a)(2)(C)
relevant to this particular question of
the criteria for an extension of the
attainment date for an PM2.5
nonattainment area subject to section
189(d), the EPA looked to guidance on
the extension provisions for particulate
matter nonattainment areas under CAA
section 188(d) in the PM2.5 SIP
Requirements Rule, given that ‘‘section
188(d) is nearly identical to CAA
section 172(a)(2)(C).’’ 39 While we did
not assert that 188(d) controls in this
situation, we did ‘‘consider[ ] the
guidance pertaining to the one-year
extension requirements under CAA
section 188(d) to persuasively inform
the requirements for a one-year
extension for a particulate matter
nonattainment area under CAA section
172(a)(2)(C).’’ 40
Comment 2.C: CCAC further claims
that ‘‘[t]he D.C. Circuit has rejected
EPA’s attempt to implement the PM2.5
standard under Subpart 1.’’
Response 2.C: The EPA disagrees with
the commenter that reliance on the
generally applicable provisions in CAA
section 172 to fill a gap in subpart 4
indicates that the EPA is improperly
implementing a PM2.5 NAAQS under
subpart 1. To the contrary, the EPA
implements the PM2.5 NAAQS in
accordance with the relevant provisions
of both subpart 1 and subpart 4, and
subpart 1 provisions continue to apply
unless specifically overridden or revised
by subpart 4. As we stated in our
proposal, the EPA does not dispute that
section 189(d) is the controlling
provision for Serious areas that, like the
San Joaquin Valley, fail to attain a PM2.5
NAAQS by the applicable attainment
date.41 Instead, the EPA is
implementing the PM2.5 standard under
subpart 4 and subpart 1, in keeping with
EPA’s longstanding interpretation that
the statutory provisions of CAA sections
172(c)(2) and 179(d)(3) govern the
attainment date for new plans required
under CAA section 189(d) for areas that
previously failed to attain by the Serious
area attainment date.42

Comment 2.D: CCAC asserts that the
PM2.5 SIP Requirements Rule and the
EPA’s implementing regulations under
40 CFR 51.1005(c) prohibit California
from requesting an extension of the
December 31, 2023 applicable
attainment deadline, and thus EPA
approval of this one-year extension
request would violate the EPA’s own
implementing regulations and is
arbitrary and capricious.
Response 2.D: The EPA disagrees that
40 CFR 51.1005(c) prohibits the
proposed attainment date extension.
The EPA’s regulations under 40 CFR
51.1005 concern extensions of the
applicable attainment date for Moderate
and Serious PM2.5 nonattainment areas.
Applicable attainment dates for PM2.5
nonattainment areas are initially set
under 40 CFR 51.1004, and 40 CFR
51.1004(a)(1) and (a)(2) follow the
mandates in CAA sections 188(c)(1) and
(c)(2), the CAA sections governing the
setting of Moderate and Serious
attainment dates, respectively. Likewise,
40 CFR 51.1005(a) and (b) follow the
requirements of CAA sections 188(d)
and (e), respectively, as the primary
sections governing extensions of the
applicable attainment date for Moderate
and Serious PM2.5 nonattainment areas.
In contrast, the authority for the
requirements in 40 CFR 51.1004(a)(3)
governing nonattainment areas subject
to CAA section 189(d) for failure to
attain by the applicable Serious area
attainment date comes from CAA
section 172(a)(2)(C), not section 188. As
explained in Response 2.A, CAA section
172 controls for purposes of setting an
attainment date for a plan required
under CAA section 189(d) because the
provisions of subpart 4, including
section 188(c), do not specifically
provide authority for establishing
attainment dates for 189(d) attainment
plans. Because a state required to adopt
and submit a 189(d) plan is subject to
the attainment date requirements of
CAA section 172(a)(2),43 40 CFR
51.1005(c) prohibits a state subject to
section 189(d) from applying for an
extension of the applicable attainment
date in excess of that which is permitted
for an attainment plan under section
189(d). For example, a Serious PM2.5
nonattainment area subject to section
189(d) may not apply for an extension
of the applicable attainment date under
section 188(e). Thus, the EPA believes
43 I.e., the nonattainment area must attain the
relevant standard as expeditiously as practicable,
but no later than 5 years from date of designation,
with the possibility of setting the date 10 years from
the date of designation under certain circumstances,
and with the possibility of additional extensions of
two one-year periods under CAA section
172(a)(2)(C).

the proposed attainment date extension,
which was made in accordance with
CAA sections 189(d) and 172, is
consistent with the relevant CAA
provisions and the EPA’s implementing
regulations.
Comment 3: CCAC comments that
‘‘[i]nstead of proposing to approve an
illegal and unauthorized one-year
extension, EPA should have made an
attainment finding.’’ CCAC asserts that
the EPA has a duty to make an
attainment finding within six months of
the attainment date, citing CAA sections
179(c)(1) and 188(b)(2) and that the EPA
instead proposes to extend the
attainment date without authority to do
so.
Response 3: As explained in
Responses 1 and 2, we believe a oneyear extension is appropriate in this
situation and authorized by the CAA if
a state meets the statutory
preconditions. In our proposal, the EPA
proposed to determine that the State has
satisfied the criteria for a one-year
extension under CAA section 172 for
the 1997 annual PM2.5 NAAQS in the
San Joaquin Valley area, and if finalized
the EPA would no longer be required
under CAA section 179(c) to make a
finding as to whether the area attained
by the December 31, 2023 attainment
date. The EPA notes that it will again
have an obligation under CAA section
179 to make a determination as to
whether the San Joaquin Valley attained
the 1997 annual PM2.5 NAAQS
following the extended December 31,
2024 attainment date. If the air quality
data indicate that the San Joaquin
Valley nonattainment area did not attain
by the December 31, 2024 attainment
date, and if the State does not qualify
for, or the EPA denies a request for, a
second one-year extension under CAA
section 172, then the EPA will issue a
finding of failure to attain at such time
in accordance with CAA section 179(c).
B. Comments From Santa Rosa
Rancheria Tachi Yokut Tribe
Comment 4: Santa Rosa Rancheria
notes that the San Joaquin Valley has
not attained the standard in nearly three
decades and opposes an extension due
to the commenter’s concerns that the
SIP is not proving effective in bringing
the area into attainment.
Response 4: As discussed in Response
1, the EPA is evaluating the requested
extension of the attainment date in light
of the relevant statutory criteria. With
respect to the air quality criterion of
CAA section 172(a)(2)(C)(ii), the EPA
has determined that the 2023 annual
mean PM2.5 concentration data from
each of the regulatory monitoring sites
in the San Joaquin Valley indicate that
VerDate Sep<11>2014
15:47 Nov 18, 2024
Jkt 265001
PM2.5 concentrations were below the
15.0 mg/m3 level of the 1997 annual
PM2.5 NAAQS, reflecting an
improvement in air quality relative to
prior years. Based in part on our review
of these data, we have determined that
the State has met the requirements
under CAA section 172(a)(2)(C) for a
one-year extension of the attainment
date. The EPA will continue to monitor
the area’s progress towards attainment
of the 1997 annual PM2.5 NAAQS and
will make a finding as to whether the
area attained the NAAQS following the
applicable extended attainment date.
Comment 5: Santa Rosa Rancheria
expresses concern that elevated PM2.5
levels are correlated with premature
mortality rates, aggravated respiratory
and cardiovascular disease, changes in
lung function, and increased respiratory
and cardiovascular symptoms.
Response 5: The EPA agrees that
epidemiological studies have shown
statistically significant correlations
between elevated PM2.5 levels and
adverse health outcomes, including
premature mortality. While this action
to approve a SIP revision and grant a
one-year extension of the attainment
date is not expected to reduce PM2.5
levels in the San Joaquin Valley, the
EPA notes that the area is also
designated nonattainment for the more
stringent 2012 annual PM2.5 NAAQS
and is subject to additional
requirements to meet those NAAQS. As
a result, the State will be continuing its
efforts to adopt and implement
additional control measures that will
continue to improve ambient PM2.5
levels in the San Joaquin Valley. On
August 22, 2024, California submitted a
revised attainment plan for the 2012
annual PM2.5 NAAQS, which includes,
among other things, the State’s control
strategy to achieve reductions in direct
PM2.5 and PM2.5 precursors to bring the
area into attainment of those NAAQS.44
While the EPA has not yet taken action
on the revised plan for the 2012 annual
PM2.5 NAAQS, we expect that
implementation of the plan will yield
additional reductions in PM2.5
concentrations in the San Joaquin
Valley.
Comment 6: The Santa Rosa
Rancheria notes that it monitors its own
air quality, and based on the data it has
collected, Santa Rosa Rancheria
challenges the representativeness of the
data relied upon by the State and the
EPA. Santa Rosa Rancheria states that

‘‘[a]ccording to the Tribe’s Air Quality
Monitoring Program, from multiple
locations around the Rancheria, as seen
in the attachment, the PM2.5 averages
well above 25 mg/m3. This data is
reported on the AQS database. Exposure
levels over 12.0 mg/m3 are considered
unsafe. The Tribe’s data shows the level
consistently double that level.’’
Response 6: As discussed in our
proposal, the EPA relies on complete,
quality-assured data gathered at
established State and Local Air
Monitoring Stations in a nonattainment
area and entered into the EPA Air
Quality System (AQS) database to
determine if an area meets the
requirement under CAA section
172(a)(2)(C) that the area had clean data
for the relevant standard in the calendar
year preceding the applicable
attainment date.45 In evaluating Santa
Rosa Rancheria’s comments, the EPA
has reviewed data collected by the Tribe
that is available in AQS. These data
indicate that Santa Rosa Rancheria
reports data from one monitoring site
(AQS ID: 06–031–0500) that measures
ozone, PM10, and several meteorological
parameters.46 PM2.5 data from this site
are not available in AQS.47
Santa Rosa Rancheria’s comment
letter notes an attachment that appeared
to be inadvertently omitted from the
comment submission. The EPA
followed up with Santa Rosa Rancheria
regarding the data referenced in its
letter, and in response, Santa Rosa
Rancheria provided data files to the EPA
that include PM2.5 data collected by
monitors on tribal land in 2021 and
2022.48 We appreciate the Tribe sharing
PM2.5 data from its monitoring network
with the EPA. However, because these
data are not complete, quality-assured
data collected at regulatory monitoring
sites that meet EPA requirements 49 and
report to the EPA’s AQS database, these
data are not eligible for comparison to
the 1997 annual PM2.5 NAAQS.
Furthermore, these data collected in
2021–2022 were collected outside the
timeframe relevant for the attainment
date extension (i.e., 2023). While not
directly relevant to this particular
action, the EPA recognizes the

importance of these supplemental data
and commends the Tribe for its
collection and use of these data to help
identify sources and inform real-time
decision-making to minimize PM2.5
exposures in the community.
Comment 7: The Tribe asserts that
research has shown that there is a strong
correlation between farming and animal
husbandry and elevated levels of
ambient PM2.5. The Tribe states that a
majority of the land in the San Joaquin
Valley is used for agriculture and that
because the Tribe is surrounded by
agriculture, the air quality on Tribal
land is more representative of the
nonattainment area than data collected
in more urban areas.
Response 7: As discussed in Response
6, the PM2.5 monitoring data collected
by Santa Rosa Rancheria does not meet
the EPA’s regulatory requirements for
comparison with the 1997 annual PM2.5
NAAQS and were collected outside the
timeframe relevant for this action.
Therefore, these data are not directly
relevant to the EPA’s evaluation of
whether the State has met the
requirements for a one-year extension of
the attainment date for the 1997 annual
PM2.5 NAAQS.
Regarding the correlation between
farming and animal husbandry and
elevated levels of PM2.5, we note that
CARB and the District are engaged in
several research efforts to better
understand the emissions from these
source categories. For example, in
spring of 2024, CARB convened a
subject matter expert review panel to
evaluate existing data and science on
NOX and ammonia emissions from soils
in California.50 CARB has also been
engaged in compiling California-specific
dairy activity data and related emissions
trends.51 While not directly relevant to
this action, we anticipate that such
research studies will help inform
continued efforts to reduce PM2.5
exposures from agricultural activities for
residents in the San Joaquin Valley.

data to the corresponding data for the
United States as a whole. The results of
the analysis are provided for
informational and transparency
purposes and are not a basis for the
EPA’s action.
IV. Final Action
For the reasons discussed in our
proposed rules and herein, the EPA is
finalizing our approval of the 15 mg/m3
Plan Amendments as a revision to the
California SIP. In doing so, we are
approving the State’s amendment to the
Valley Incentive Measure for the
purposes of emissions reductions in
2023 and the State’s revision to the
aggregate tonnage commitment in the 15
mg/m3 SIP Revision to reflect that it has
been satisfied by the Valley Incentive
Measure. We are also approving the
State’s demonstration that the Valley
Incentive Measure has achieved
emissions reductions of 5.0 tpd of NOX
and 0.27 tpd of direct PM2.5 in the year
2023 and crediting those reductions
toward the emissions reduction
commitment in the California SIP.
Additionally, in response to a request
from the State of California on May 23,
2024, the EPA is granting a one-year
extension to the applicable attainment
date for the 1997 annual PM2.5 NAAQS
for the San Joaquin Valley
nonattainment area. This final action to
extend the applicable attainment date
from December 31, 2023, to December
31, 2024, for this nonattainment area is
based on the State’s compliance with
the requirements in the applicable SIP
for the area and on the 2023 PM2.5
monitoring data from sites in the San
Joaquin Valley nonattainment area.
V. Statutory and Executive Order
Reviews
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 approve state choices,
provided that they meet the criteria of
the Act. Accordingly, this final action
merely approves a state plan as meeting
federal requirements and grants a state
request for an attainment date extension
consistent with federal requirements
and does not impose additional
and demographic indicators. EJSCREEN is available
at https://www.epa.gov/ejscreen/what-ejscreen. The
EPA used EJSCREEN to obtain environmental and
demographic indicators representing each of the
eight counties in the San Joaquin Valley.

requirements beyond those imposed by
state law. For that reason, this action:
• 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);
• Does not impose an information
collection burden under the provisions
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• 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.);
• 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);
• Does not have federalism

• Is not subject to Executive Order
13045 (62 FR 19885, April 23, 1997)
because it approves a state program;
• Is not a significant regulatory action
subject to Executive Order 13211 (66 FR

• 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 CAA.
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 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,
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. Executive Order
14096 (Revitalizing Our Nation’s
Commitment to Environmental Justice
for All, 88 FR 25251, April 26, 2023)
builds on and supplements E.O. 12898
and defines EJ as, among other things,
‘‘the just treatment and meaningful

activities that affect human health and
the environment.’’
The State did not evaluate EJ
considerations as part of its SIP
submittal; the CAA and applicable
implementing regulations neither
prohibit nor require such an evaluation.
Consistent with the EPA’s discretion
under the CAA, the EPA performed an
EJ analysis, as is described above in the
section titled, ‘‘Environmental Justice
Considerations.’’ The analysis was done
for the purpose of providing additional
context and information about this
rulemaking to the public, not as a basis
of the action. Due to the nature of the
action being taken here, this action is
expected to have a neutral impact on the
air quality of the affected area. In
addition, there is no information in the
record upon which this decision is
based inconsistent with the stated goal
of E.O. 12898 of achieving EJ for
communities with EJ concerns.
This action is subject to the
Congressional Review Act, and EPA will
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. This action
is not a ‘‘major rule’’ as defined by 5
U.S.C. 804(2). Under section 307(b)(1) of
the CAA, petitions for judicial review of
this action must be filed in the United
States Court of Appeals for the
appropriate circuit by January 21, 2025.
Filing a petition for reconsideration by
the Administrator of this final rule does
not affect the finality of this action for
the purposes of judicial review nor does
it extend the time within which a
petition for judicial review may be filed,
and shall not postpone the effectiveness
of such rule or action. This action may
not be challenged later in proceedings to
enforce its requirements. (See section

I. Summary of the Proposed Actions
On July 8, 2024, the EPA proposed two actions related to the CAA
requirements for the 1997 annual PM2.5 NAAQS in the San
Joaquin Valley Serious nonattainment area.
In the first action, under CAA section 110(k)(3), the EPA proposed
to approve through parallel processing the ``Amendments to the 15
[micro]g/m\3\ SIP Revision and Agricultural Equipment Incentive Measure
for the 1997 PM2.5 Standard'' (``15 [micro]g/m\3\ Plan
Amendments'') as a revision to the California SIP.\1\ The 15 [micro]g/
m\3\ Plan Amendments seek to amend a SIP-approved measure, the
``Accelerated Turnover of Agricultural Equipment Incentive Projects''
(``Valley Incentive Measure''), to include a quantification of the
emissions reductions for the year 2023 from existing agricultural
equipment projects from the California Air Resources Board's (CARB's)
Carl Moyer Memorial Air Quality Standards Attainment Program (``Carl
Moyer'') and CARB's Funding Agricultural Replacement Measures for
Emission Reductions (FARMER) program and seek EPA approval of those
emission reductions for SIP credit. The 15 [micro]g/m\3\ Plan
Amendments also seek to revise the aggregate tonnage commitment in the
attainment plan for the 1997 annual PM2.5 NAAQS (i.e., the
``Attainment Plan Revision for the 1997 Annual PM2.5
Standard'' (``15 [micro]g/m\3\ SIP Revision'')) by replacing it with a
commitment to achieve the same reductions from the Valley Incentive
Measure. As part of the EPA's proposal to approve the 15 [micro]g/m\3\
Plan Amendments, we proposed to approve the State's demonstration that
the Valley Incentive Measure has achieved emissions reductions of 5.0
tons per day (tpd) of nitrogen oxides (NOX) and 0.27 tpd of
direct PM2.5 in the year 2023, and proposed to credit the
reductions as a substitute measure to meet the aggregate tonnage
commitment in the 15 [micro]g/m\3\ SIP Revision.\2\
---------------------------------------------------------------------------
\1\ 89 FR 55896 (July 8, 2024).
\2\ Id.
---------------------------------------------------------------------------
In the second action, based in part on our proposal to approve the
15 [micro]g/m\3\ Plan Amendments, the EPA proposed to grant
California's request for a one-year extension of the applicable
attainment date from December 31, 2023, to December 31, 2024, for the
1997 annual PM2.5 San Joaquin Valley, California,
nonattainment area.\3\ The proposed action to extend the applicable
attainment date for this nonattainment area was based on the EPA's
evaluation of air quality monitoring data and extension request
submitted by the State of California, and our determination that the
State has satisfied the two statutory criteria for a one-year extension
under CAA section 172(a)(2)(C): The State has complied with all
requirements and commitments pertaining to the area in the applicable
implementation plan, and in accordance with guidance published by the
Administrator, no more than the minimal number of exceedances of the
relevant national ambient air quality standard has occurred in the area
in the year preceding the Extension Year.
---------------------------------------------------------------------------
\3\ 89 FR 55901 (July 8, 2024).
---------------------------------------------------------------------------
For details regarding the EPA's reasons for proposing to approve
the 15 [micro]g/m\3\ Plan Amendments and to grant the one-year
extension, please see the July 8, 2024 proposal notices.\4\
---------------------------------------------------------------------------
\4\ 89 FR 55896 and 89 FR 55901.
---------------------------------------------------------------------------
On August 22, 2024, California submitted the final version of the
15 [micro]g/m\3\ Plan Amendments to the EPA as a
[[Page 91264]]
revision to the California SIP.\5\ We have reviewed this submittal and
find that it fulfills the SIP completeness criteria of 40 CFR part 51,
Appendix V. The SIP submission also includes evidence that adequate
public notice was given and that an opportunity for a public hearing
was provided consistent with the EPA's implementing regulations in 40
CFR 51.102. Specifically, CARB provided public notice and opportunity
for public comment prior to its July 25, 2024 public hearing on and
adoption of the 15 [micro]g/m\3\ Plan Amendments.\6\ The SIP submission
includes proof of publication notices for the public hearing and
includes copies of the written and oral comments received during the
State's public review processes and CARB's responses thereto.\7\
Therefore, we find that the 15 [micro]g/m\3\ Plan Amendments meet the
procedural requirements for public notice and hearing in CAA sections
110(a) and 110(l) and 40 CFR 51.102.

\25\ One of the comments titled ``Comments on `Review of San
Joaquin Valley 2024 Plan for the 12 [micro]g/m\3\ Annual
PM2.5 Standard' by CARB, June 14, 2024'' concerns
PM2.5 concentrations in San Joaquin Valley; however, the
title of the comment and the analysis therein indicates that it is
directed at the State's attainment plan for the 2012 annual
PM2.5 NAAQS. The comment presents evidence that purports
to show that the State's attainment modeling for the 2012 annual
PM2.5 NAAQS is flawed; however such modeling is not
relevant to this action that concerns whether the State has met the
requirements for a one-year extension of the attainment date for the
1997 annual PM2.5 NAAQS. Thus, the comment is not germane
to this action and does not necessitate any further response at this
time. The EPA will review the State's attainment plan for the 2012
annual PM2.5 NAAQS for compliance with the requirements
of the CAA and the EPA's regulations, and will determine, following
notice-and-comment rulemaking, whether the submission satisfies all
applicable CAA requirements. We encourage the commenter to resubmit
these comments as appropriate during such a future rulemaking.
---------------------------------------------------------------------------
A. Comments From CCAC
Comment 1: CCAC comments that the Valley has a history of poor air
quality and of failing to attain the various NAAQS by their respective
deadlines.
[[Page 91265]]
Citing PM2.5 design values for 2018-2020, 2019-2021, and
2020-2022 of 17.6 [micro]g/m\3\, 17.8 [micro]g/m\3\, and 18.8 [micro]g/
m\3\, CCAC claims that PM2.5 concentrations have not
improved and remain well above the 15 [micro]g/m\3\ level of the 1997
annual PM2.5 NAAQS. CCAC also states that ``EPA [has]
correctly recognized the environmental injustice San Joaquin Valley
residents endure'' and summarizes findings from the EPA's prior
environmental justice (EJ) analyses for the area.
Response 1: The EPA acknowledges that there are communities with EJ
concerns in the San Joaquin Valley and does not dispute the challenges
associated with attaining the 1997 annual PM2.5 NAAQS in
this area. We also acknowledge that the Demographic Index analysis the
EPA discussed in the proposal to grant the extension of the attainment
date indicates that the indices that reflect the area's percent
minority and percent low-income populations are above the national
averages for those indices.\26\ Nevertheless, the CAA provides states
the opportunity to request an extension of the applicable attainment
date for a nonattainment area if they meet certain statutory criteria,
including that the area met the air quality standard in question in the
year leading up to the applicable attainment date.\27\
---------------------------------------------------------------------------
\26\ 89 FR 55901, 55909.
\27\ CAA section 172(a)(2)(C).
---------------------------------------------------------------------------
CCAC also expressed concern that PM2.5 concentrations in
the Valley have not improved in recent years, and that this pattern
should weigh against the extension of the attainment date. The EPA must
assess whether to grant the attainment date extension in light of the
statutory criteria. We note that CCAC relies on design values \28\ to
evaluate the pace of improvement in the area. However, design values,
which reflect the annual average over a three-year period, are not the
metric that EPA uses to determine whether a state qualifies for a one-
year attainment date extension. Rather, pursuant to section
172(a)(2)(C) of the Act, the EPA looks to the monitor data in the year
leading up to the attainment date (i.e., in this case, calendar year
2023) to assess an area's recent progress. As discussed in the proposal
to grant the one-year extension of the attainment date, the EPA
reviewed 2023 annual mean concentrations at each of the regulatory
monitoring sites in the San Joaquin Valley and determined that such
data indicate that PM2.5 concentrations were below the 15.0
[micro]g/m\3\ level of the 1997 annual PM2.5 NAAQS.\29\
---------------------------------------------------------------------------
\28\ For information about how the EPA calculates design values,
see 40 CFR 50.7 and 40 CFR part 50, Appendix N, section 4.1(b).
\29\ 89 FR 55901, 55909.
---------------------------------------------------------------------------
Moreover, 2023 annual mean concentrations were lower than annual
mean concentrations in 2021 and 2022, indicating an improvement in air
quality conditions in 2023 relative to previous years.\30\ This is true
even without considering potential impacts from any exceptional events
during that timeframe.\31\ \32\
---------------------------------------------------------------------------
\30\ EPA AQS Design Value Report, AMP480, accessed May 17, 2024
(User ID: STSAI, Report Request ID: 2193813).
\31\ Exceptional Events are unusual or naturally occurring
events that can affect air quality but are not reasonably
controllable using techniques that tribal, state or local air
agencies may implement in order to attain and maintain the NAAQS.
Exceptional events may include wildfires, high wind dust events,
prescribed fires, stratospheric ozone intrusions, and volcanic and
seismic activities.
\32\ In the May 14, 2024, letter submitting documentation to
support the State's request for an attainment date extension, the
District noted that they and CARB ``are evaluating potential
documentation to remove exceptional events (including wildfire
impacts) from the 2021-2023 period, as allowed under the CAA and EPA
policies.'' Letter dated May 14, 2024, from Samir Sheikh, Executive
Director/APCO, SJVUAPCD, to Steven S. Cliff, Executive Officer,
CARB, Subject: ``RE: Attainment Date Extension for the 1997 Annual
PM2.5 Standard for the San Joaquin Valley Nonattainment
Area.''
---------------------------------------------------------------------------
The EPA notes that while this final action extends the attainment
date for the San Joaquin Valley for the 1997 annual PM2.5
NAAQS to December 31, 2024, the area will remain classified as Serious
nonattainment for those NAAQS and is not relieved of any planning
obligations under the CAA. Following the December 31, 2024 attainment
date, the State and the EPA will assess whether the area has attained
the 1997 annual PM2.5 NAAQS. If the area has met the NAAQS,
the EPA will make a determination that the area attained by the
attainment date. If the area has not met the NAAQS, the State may
request a second one-year extension if the area meets the CAA
requirements for such an extension. If the State does not qualify for,
or the EPA denies a request for, a second one-year extension under CAA
section 172, then the EPA will issue a finding of failure to attain and
the State will become subject to additional CAA requirements to achieve
attainment of the 1997 annual PM2.5 NAAQS in the San Joaquin
Valley area.
Comment 2.A: CCAC asserts that the EPA does not have authority to
grant a one-year extension of the attainment date for the San Joaquin
Valley for the 1997 annual PM2.5 NAAQS under CAA section
172(a)(2)(C). Specifically, CCAC notes that subpart 4 of Part D of
Title I of the Act provides for attainment date extensions for
PM2.5 nonattainment areas under specific circumstances under
section 188, and thus section 188 controls the question of whether the
EPA can grant an attainment date extension for a Serious
PM2.5 nonattainment area that fails to attain by the
applicable attainment date. CCAC asserts that attainment date
extensions for Serious nonattainment areas are addressed by CAA section
188(e), that California did not request such an extension, and that
therefore such extension is not available at this time to the San
Joaquin Valley for the 1997 annual PM2.5 NAAQS.
Response 2.A: The EPA disagrees with the commenter that the
attainment date extension provisions under CAA section 188 control the
present action.
As CCAC accurately explains, the EPA reclassified the San Joaquin
Valley as Serious nonattainment for the 1997 annual PM2.5
NAAQS effective May 7, 2015.\33\ The following year, the EPA found that
the San Joaquin Valley failed to attain by the applicable Serious
attainment date and that sections 179(d) and 189(d) of the CAA governed
all subsequent plan requirements and attainment deadlines.\34\
---------------------------------------------------------------------------
\33\ 80 FR 18528 (April 7, 2015).
\34\ 81 FR 84481 (November 23, 2016).
---------------------------------------------------------------------------
Crucially, following a finding of failure to attain for a Serious
PM2.5 nonattainment area, CAA section 189(d) does not
provide for a specific attainment date, and it instead requires:
[T]he State in which such area is located shall, after notice
and opportunity for public comment, submit within 12 months after
the applicable attainment date, plan revisions which provide for
attainment of the [PM2.5] air quality standard and, from
the date of such submission until attainment for an annual reduction
in [PM2.5] or [PM2.5] precursor emissions
within the area of not less than 5 percent of the amount of such
emissions as reported in the most recent inventory prepared for such
area.\35\
---------------------------------------------------------------------------
\35\ CAA section 189(d).
With respect to the new applicable attainment date for an area
governed by CAA section 189(d), the EPA explained in the
PM2.5 SIP Requirements Rule \36\ that:
---------------------------------------------------------------------------
\36\ 81 FR 58010 (August 24, 2016).
[T]he final rule includes the overarching requirement for a
Serious area that failed to attain by the previous attainment date
to establish a new date for attaining the standard as expeditiously
as practicable. However, neither CAA section 189(d) nor other
sections in subpart 4 explicitly establish or provide the authority
to establish a new attainment date for the area. Therefore, once an
area is beyond the attainment dates that Congress specified in
subpart 4 for the
[[Page 91266]]
PM10 NAAQS, the EPA must look to other provisions of part
D of the CAA to provide authority for a new attainment date.
Sections 179(d)(3) and 172(a)(2) of the CAA provide generally
applicable attainment dates that fill the gap in the statute left
for areas subject to the requirements of CAA section 189(d). Thus,
for a PM2.5 nonattainment area subject to CAA section
189(d) requirements, the EPA must establish a new attainment date
according to the provisions of CAA section 179(d)(3) and 172(a)(2).
The EPA has followed this same approach in the past for
PM10 nonattainment areas governed by subpart 4
nonattainment requirements.\37\
---------------------------------------------------------------------------
\37\ Id. at 58106.
Thus, subpart 4 controls the requirements for an attainment plan
under CAA section 189(d); however, after a Serious PM2.5
nonattainment area fails to attain by the attainment date, the
applicable attainment date for a Serious PM2.5 nonattainment
area subject to the requirements of CAA section 189(d) is controlled by
the generally applicable provisions in subpart 1 of part D, CAA section
172.
Contrary to the commenter's assertion, section 172 explicitly
provides for the extension that the EPA is finalizing as part of this
action. The commenter cites CAA section 172(a)(2)(D), which states,
``[t]his paragraph shall not apply with respect to nonattainment areas
for which attainment dates are specifically provided under other
provisions of this part.'' But as explained above, the attainment date
for an attainment plan required under CAA section 189(d) is not
specifically provided under the provisions in subpart 4, which is why
the EPA relied on section 172 in setting the December 31, 2023
attainment date for the San Joaquin Valley.\38\
---------------------------------------------------------------------------
\38\ 81 FR 84481, 84482.
---------------------------------------------------------------------------
Because CAA section 172 controls for purposes of setting an
attainment date for a plan required under CAA section 189(d), it is
logical and reasonable that the generally applicable provisions in
section 172 would control an extension of that attainment date in the
absence of any specific authority in subpart 4 for such extensions.
Comment 2.B: CCAC claims that the EPA evaluates the State's request
for an attainment date extension pursuant to EPA guidance on the
implementation of CAA section 188(d), which concerns attainment date
extensions for Moderate PM2.5 nonattainment areas, and
asserts that the EPA does not have authority to apply such provisions
to a Serious PM2.5 nonattainment area.
Response 2.B: The EPA is not granting the extension pursuant to
section 188(d) of the Act. Rather, because section 172(a)(2)(C) does
not have PM-specific provisions and because the EPA has not issued
guidance on how to implement the provisions of section 172(a)(2)(C)
relevant to this particular question of the criteria for an extension
of the attainment date for an PM2.5 nonattainment area
subject to section 189(d), the EPA looked to guidance on the extension
provisions for particulate matter nonattainment areas under CAA section
188(d) in the PM2.5 SIP Requirements Rule, given that
``section 188(d) is nearly identical to CAA section 172(a)(2)(C).''
\39\ While we did not assert that 188(d) controls in this situation, we
did ``consider[ ] the guidance pertaining to the one-year extension
requirements under CAA section 188(d) to persuasively inform the
requirements for a one-year extension for a particulate matter
nonattainment area under CAA section 172(a)(2)(C).'' \40\

---------------------------------------------------------------------------
Comment 2.C: CCAC further claims that ``[t]he D.C. Circuit has
rejected EPA's attempt to implement the PM2.5 standard under
Subpart 1.''
Response 2.C: The EPA disagrees with the commenter that reliance on
the generally applicable provisions in CAA section 172 to fill a gap in
subpart 4 indicates that the EPA is improperly implementing a
PM2.5 NAAQS under subpart 1. To the contrary, the EPA
implements the PM2.5 NAAQS in accordance with the relevant
provisions of both subpart 1 and subpart 4, and subpart 1 provisions
continue to apply unless specifically overridden or revised by subpart
4. As we stated in our proposal, the EPA does not dispute that section
189(d) is the controlling provision for Serious areas that, like the
San Joaquin Valley, fail to attain a PM2.5 NAAQS by the
applicable attainment date.\41\ Instead, the EPA is implementing the
PM2.5 standard under subpart 4 and subpart 1, in keeping
with EPA's longstanding interpretation that the statutory provisions of
CAA sections 172(c)(2) and 179(d)(3) govern the attainment date for new
plans required under CAA section 189(d) for areas that previously
failed to attain by the Serious area attainment date.\42\
---------------------------------------------------------------------------
\41\ ``Following a January 4, 2013 decision of the U.S. Court of
Appeals for the D.C. Circuit . . . the EPA acknowledged that states
must meet both subpart 1 and subpart 4 requirements in nonattainment
plan SIP submissions for the 1997 24-hour and annual
PM2.5 NAAQS.'' Id. at 55903.
\42\ See, e.g., 72 FR 31183 (June 6, 2007) (finding that the
Phoenix PM10 Serious nonattainment area failed to attain
the standard by the December 31, 2006 attainment deadline and
implementing the new attainment date for an attainment plan under
CAA section 189(d) pursuant to sections 172 and 179).
---------------------------------------------------------------------------
Comment 2.D: CCAC asserts that the PM2.5 SIP
Requirements Rule and the EPA's implementing regulations under 40 CFR
51.1005(c) prohibit California from requesting an extension of the
December 31, 2023 applicable attainment deadline, and thus EPA approval
of this one-year extension request would violate the EPA's own
implementing regulations and is arbitrary and capricious.
Response 2.D: The EPA disagrees that 40 CFR 51.1005(c) prohibits
the proposed attainment date extension. The EPA's regulations under 40
CFR 51.1005 concern extensions of the applicable attainment date for
Moderate and Serious PM2.5 nonattainment areas. Applicable
attainment dates for PM2.5 nonattainment areas are initially
set under 40 CFR 51.1004, and 40 CFR 51.1004(a)(1) and (a)(2) follow
the mandates in CAA sections 188(c)(1) and (c)(2), the CAA sections
governing the setting of Moderate and Serious attainment dates,
respectively. Likewise, 40 CFR 51.1005(a) and (b) follow the
requirements of CAA sections 188(d) and (e), respectively, as the
primary sections governing extensions of the applicable attainment date
for Moderate and Serious PM2.5 nonattainment areas.
In contrast, the authority for the requirements in 40 CFR
51.1004(a)(3) governing nonattainment areas subject to CAA section
189(d) for failure to attain by the applicable Serious area attainment
date comes from CAA section 172(a)(2)(C), not section 188. As explained
in Response 2.A, CAA section 172 controls for purposes of setting an
attainment date for a plan required under CAA section 189(d) because
the provisions of subpart 4, including section 188(c), do not
specifically provide authority for establishing attainment dates for
189(d) attainment plans. Because a state required to adopt and submit a
189(d) plan is subject to the attainment date requirements of CAA
section 172(a)(2),\43\ 40 CFR 51.1005(c) prohibits a state subject to
section 189(d) from applying for an extension of the applicable
attainment date in excess of that which is permitted for an attainment
plan under section 189(d). For example, a Serious PM2.5
nonattainment area subject to section 189(d) may not apply for an
extension of the applicable attainment date under section 188(e). Thus,
the EPA believes
[[Page 91267]]
the proposed attainment date extension, which was made in accordance
with CAA sections 189(d) and 172, is consistent with the relevant CAA
provisions and the EPA's implementing regulations.
---------------------------------------------------------------------------
\43\ I.e., the nonattainment area must attain the relevant
standard as expeditiously as practicable, but no later than 5 years
from date of designation, with the possibility of setting the date
10 years from the date of designation under certain circumstances,
and with the possibility of additional extensions of two one-year
periods under CAA section 172(a)(2)(C).
---------------------------------------------------------------------------
Comment 3: CCAC comments that ``[i]nstead of proposing to approve
an illegal and unauthorized one-year extension, EPA should have made an
attainment finding.'' CCAC asserts that the EPA has a duty to make an
attainment finding within six months of the attainment date, citing CAA
sections 179(c)(1) and 188(b)(2) and that the EPA instead proposes to
extend the attainment date without authority to do so.
Response 3: As explained in Responses 1 and 2, we believe a one-
year extension is appropriate in this situation and authorized by the
CAA if a state meets the statutory preconditions. In our proposal, the
EPA proposed to determine that the State has satisfied the criteria for
a one-year extension under CAA section 172 for the 1997 annual
PM2.5 NAAQS in the San Joaquin Valley area, and if finalized
the EPA would no longer be required under CAA section 179(c) to make a
finding as to whether the area attained by the December 31, 2023
attainment date. The EPA notes that it will again have an obligation
under CAA section 179 to make a determination as to whether the San
Joaquin Valley attained the 1997 annual PM2.5 NAAQS
following the extended December 31, 2024 attainment date. If the air
quality data indicate that the San Joaquin Valley nonattainment area
did not attain by the December 31, 2024 attainment date, and if the
State does not qualify for, or the EPA denies a request for, a second
one-year extension under CAA section 172, then the EPA will issue a
finding of failure to attain at such time in accordance with CAA
section 179(c).
B. Comments From Santa Rosa Rancheria Tachi Yokut Tribe
Comment 4: Santa Rosa Rancheria notes that the San Joaquin Valley
has not attained the standard in nearly three decades and opposes an
extension due to the commenter's concerns that the SIP is not proving
effective in bringing the area into attainment.
Response 4: As discussed in Response 1, the EPA is evaluating the
requested extension of the attainment date in light of the relevant
statutory criteria. With respect to the air quality criterion of CAA
section 172(a)(2)(C)(ii), the EPA has determined that the 2023 annual
mean PM2.5 concentration data from each of the regulatory
monitoring sites in the San Joaquin Valley indicate that
PM2.5 concentrations were below the 15.0 [micro]g/m\3\ level
of the 1997 annual PM2.5 NAAQS, reflecting an improvement in
air quality relative to prior years. Based in part on our review of
these data, we have determined that the State has met the requirements
under CAA section 172(a)(2)(C) for a one-year extension of the
attainment date. The EPA will continue to monitor the area's progress
towards attainment of the 1997 annual PM2.5 NAAQS and will
make a finding as to whether the area attained the NAAQS following the
applicable extended attainment date.
Comment 5: Santa Rosa Rancheria expresses concern that elevated
PM2.5 levels are correlated with premature mortality rates,
aggravated respiratory and cardiovascular disease, changes in lung
function, and increased respiratory and cardiovascular symptoms.
Response 5: The EPA agrees that epidemiological studies have shown
statistically significant correlations between elevated
PM2.5 levels and adverse health outcomes, including
premature mortality. While this action to approve a SIP revision and
grant a one-year extension of the attainment date is not expected to
reduce PM2.5 levels in the San Joaquin Valley, the EPA notes
that the area is also designated nonattainment for the more stringent
2012 annual PM2.5 NAAQS and is subject to additional
requirements to meet those NAAQS. As a result, the State will be
continuing its efforts to adopt and implement additional control
measures that will continue to improve ambient PM2.5 levels
in the San Joaquin Valley. On August 22, 2024, California submitted a
revised attainment plan for the 2012 annual PM2.5 NAAQS,
which includes, among other things, the State's control strategy to
achieve reductions in direct PM2.5 and PM2.5
precursors to bring the area into attainment of those NAAQS.\44\ While
the EPA has not yet taken action on the revised plan for the 2012
annual PM2.5 NAAQS, we expect that implementation of the
plan will yield additional reductions in PM2.5
concentrations in the San Joaquin Valley.

Executive Officer, CARB, to Martha Guzman, Regional Administrator,
EPA Region 9, with enclosures (submitted electronically August 22,
2024, and supplement submitted electronically October 7, 2024).
---------------------------------------------------------------------------
Comment 6: The Santa Rosa Rancheria notes that it monitors its own
air quality, and based on the data it has collected, Santa Rosa
Rancheria challenges the representativeness of the data relied upon by
the State and the EPA. Santa Rosa Rancheria states that ``[a]ccording
to the Tribe's Air Quality Monitoring Program, from multiple locations
around the Rancheria, as seen in the attachment, the PM2.5
averages well above 25 [micro]g/m\3\. This data is reported on the AQS
database. Exposure levels over 12.0 [micro]g/m\3\ are considered
unsafe. The Tribe's data shows the level consistently double that
level.''
Response 6: As discussed in our proposal, the EPA relies on
complete, quality-assured data gathered at established State and Local
Air Monitoring Stations in a nonattainment area and entered into the
EPA Air Quality System (AQS) database to determine if an area meets the
requirement under CAA section 172(a)(2)(C) that the area had clean data
for the relevant standard in the calendar year preceding the applicable
attainment date.\45\ In evaluating Santa Rosa Rancheria's comments, the
EPA has reviewed data collected by the Tribe that is available in AQS.
These data indicate that Santa Rosa Rancheria reports data from one
monitoring site (AQS ID: 06-031-0500) that measures ozone,
PM10, and several meteorological parameters.\46\
PM2.5 data from this site are not available in AQS.\47\

---------------------------------------------------------------------------
Santa Rosa Rancheria's comment letter notes an attachment that
appeared to be inadvertently omitted from the comment submission. The
EPA followed up with Santa Rosa Rancheria regarding the data referenced
in its letter, and in response, Santa Rosa Rancheria provided data
files to the EPA that include PM2.5 data collected by
monitors on tribal land in 2021 and 2022.\48\ We appreciate the Tribe
sharing PM2.5 data from its monitoring network with the EPA.
However, because these data are not complete, quality-assured data
collected at regulatory monitoring sites that meet EPA requirements
\49\ and report to the EPA's AQS database, these data are not eligible
for comparison to the 1997 annual PM2.5 NAAQS. Furthermore,
these data collected in 2021-2022 were collected outside the timeframe
relevant for the attainment date extension (i.e., 2023). While not
directly relevant to this particular action, the EPA recognizes the
[[Page 91268]]
importance of these supplemental data and commends the Tribe for its
collection and use of these data to help identify sources and inform
real-time decision-making to minimize PM2.5 exposures in the
community.

\48\ Email dated September 4, 2024, from George Bernard,
Environmental Director, Santa Rosa Rancheria Tachi Yokut Tribe, to
Lily Lee, Assistant Director, Air & Radiation Division, EPA Region
IX, with 84 attachments.
\49\ Regulatory monitoring requires adherence to 40 CFR parts
50, 53, and 58 and the related appendices and the use of designated
federal reference or federal equivalent methods.
---------------------------------------------------------------------------
Comment 7: The Tribe asserts that research has shown that there is
a strong correlation between farming and animal husbandry and elevated
levels of ambient PM2.5. The Tribe states that a majority of
the land in the San Joaquin Valley is used for agriculture and that
because the Tribe is surrounded by agriculture, the air quality on
Tribal land is more representative of the nonattainment area than data
collected in more urban areas.
Response 7: As discussed in Response 6, the PM2.5
monitoring data collected by Santa Rosa Rancheria does not meet the
EPA's regulatory requirements for comparison with the 1997 annual
PM2.5 NAAQS and were collected outside the timeframe
relevant for this action. Therefore, these data are not directly
relevant to the EPA's evaluation of whether the State has met the
requirements for a one-year extension of the attainment date for the
1997 annual PM2.5 NAAQS.
Regarding the correlation between farming and animal husbandry and
elevated levels of PM2.5, we note that CARB and the District
are engaged in several research efforts to better understand the
emissions from these source categories. For example, in spring of 2024,
CARB convened a subject matter expert review panel to evaluate existing
data and science on NOX and ammonia emissions from soils in
California.\50\ CARB has also been engaged in compiling California-
specific dairy activity data and related emissions trends.\51\ While
not directly relevant to this action, we anticipate that such research
studies will help inform continued efforts to reduce PM2.5
exposures from agricultural activities for residents in the San Joaquin
Valley.

III. Environmental Justice Considerations
As described in detail in our proposals, the EPA reviewed
environmental and demographic data for the San Joaquin Valley using the
EPA's EJ screening and mapping tool (``EJSCREEN'') \52\ \53\ and
compared the data to the corresponding data for the United States as a
whole. The results of the analysis are provided for informational and
transparency purposes and are not a basis for the EPA's action.
---------------------------------------------------------------------------
\52\ EJSCREEN provides a nationally consistent dataset and
approach for combining environmental and demographic indicators.
EJSCREEN is available at https://www.epa.gov/ejscreen/what-ejscreen.
The EPA used EJSCREEN to obtain environmental and demographic
indicators representing each of the eight counties in the San
Joaquin Valley.

of the San Joaquin Valley Nonattainment Area,'' August 2022.
---------------------------------------------------------------------------
IV. Final Action
For the reasons discussed in our proposed rules and herein, the EPA
is finalizing our approval of the 15 [micro]g/m\3\ Plan Amendments as a
revision to the California SIP. In doing so, we are approving the
State's amendment to the Valley Incentive Measure for the purposes of
emissions reductions in 2023 and the State's revision to the aggregate
tonnage commitment in the 15 [micro]g/m\3\ SIP Revision to reflect that
it has been satisfied by the Valley Incentive Measure. We are also
approving the State's demonstration that the Valley Incentive Measure
has achieved emissions reductions of 5.0 tpd of NOX and 0.27
tpd of direct PM2.5 in the year 2023 and crediting those
reductions toward the emissions reduction commitment in the California
SIP.
Additionally, in response to a request from the State of California
on May 23, 2024, the EPA is granting a one-year extension to the
applicable attainment date for the 1997 annual PM2.5 NAAQS
for the San Joaquin Valley nonattainment area. This final action to
extend the applicable attainment date from December 31, 2023, to
December 31, 2024, for this nonattainment area is based on the State's
compliance with the requirements in the applicable SIP for the area and
on the 2023 PM2.5 monitoring data from sites in the San
Joaquin Valley nonattainment area.
V. Statutory and Executive Order Reviews
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 approve state choices,
provided that they meet the criteria of the Act. Accordingly, this
final action merely approves a state plan as meeting federal
requirements and grants a state request for an attainment date
extension consistent with federal requirements and does not impose
additional requirements beyond those imposed by state law. For that
reason, this action:
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);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
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.);
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);
Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it approves a state program;
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
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 CAA.
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 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,
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.
Executive Order 14096 (Revitalizing Our Nation's Commitment to
Environmental Justice for All, 88 FR 25251, April 26, 2023) builds on
and supplements E.O. 12898 and defines EJ as, among other things, ``the
just treatment and meaningful involvement of all people, regardless of
income, race, color, national origin, or Tribal affiliation, or
disability in agency
[[Page 91269]]
decision-making and other Federal activities that affect human health
and the environment.''
The State did not evaluate EJ considerations as part of its SIP
submittal; the CAA and applicable implementing regulations neither
prohibit nor require such an evaluation. Consistent with the EPA's
discretion under the CAA, the EPA performed an EJ analysis, as is
described above in the section titled, ``Environmental Justice
Considerations.'' The analysis was done for the purpose of providing
additional context and information about this rulemaking to the public,
not as a basis of the action. Due to the nature of the action being
taken here, this action is expected to have a neutral impact on the air
quality of the affected area. In addition, there is no information in
the record upon which this decision is based inconsistent with the
stated goal of E.O. 12898 of achieving EJ for communities with EJ
concerns.
This action is subject to the Congressional Review Act, and EPA
will submit a rule report to each House of the Congress and to the
Comptroller General of the United States. This action is not a ``major
rule'' as defined by 5 U.S.C. 804(2). Under section 307(b)(1) of the
CAA, petitions for judicial review of this action must be filed in the
United States Court of Appeals for the appropriate circuit by January
21, 2025. Filing a petition for reconsideration by the Administrator of
this final rule does not affect the finality of this action for the
purposes of judicial review nor does it extend the time within which a
petition for judicial review may be filed, and shall not postpone the
effectiveness of such rule or action. This action may not be challenged
later in proceedings to enforce its requirements. (See section
307(b)(2).)
