SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain The Boeing Company
Model MD-11 and MD-11F airplanes. The NPRM published in the Federal
Register on May 30, 2017 (82 FR 24597). The NPRM was prompted by fuel
system reviews conducted by the manufacturer. The NPRM proposed to
require a one-time inspection of the wire assemblies of the tail fuel
tank transfer pumps to determine if metallic transitions are installed
at the wire harness breakouts, and corrective actions if necessary. We
are issuing this AD to detect and correct potential ignition sources
inside the tail fuel tank,

which, in combination with flammable vapors, could result in a fuel
tank fire or explosion, and consequent loss of the airplane.

Comments

    We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
NPRM and the FAA's response to each comment.

Supportive Comment

    The Air Line Pilots Association International stated that it agreed
with the intent of the NPRM.

Request To Clarify the Description of the Unsafe Condition

    Boeing asked that we clarify the description of the unsafe
condition identified in paragraph (e) of the proposed AD to add the
potential of fuel starvation as the end-level effect. Boeing stated
that referenced service information specifies that the unsafe condition
could result in engine fuel starvation.
    We agree that damaged wires could result in fuel starvation as a
potential unsafe condition. However, we have no SFAR88 analysis or
service difficulty reports associated with the loss of system functions
or fuel starvation from the chafed or damaged wires identified in this
AD. We do have previous Special Federal Aviation Regulation 88 (SFAR88)
ADs for wire harnesses in the same area that were issued to prevent
wire chafing and potential ignition sources inside the fuel tank. The
actions required by this AD are intended primarily to reduce the risk
of other incidents of wires chafing and subsequent fuel tank fire or
explosion. Therefore, we have made no change to this AD in this regard.

Request To Change Certain Estimates in Costs of Compliance Section

    FedEx asked that the work-hours under the On-Condition Costs for
the replacement be increased from 16 to 100. FedEx stated that the
replacement cost specifies 16 work-hours, but noted that replacement of
only one affected part will actually take about 100 hours. FedEx added
that 100 work-hours is only for one damaged wire assembly.
    United Parcel Service (UPS) asked that the work-hours under the On-
Condition Costs for the replacement be increased from 16 to 244. UPS
stated that it has previously replaced this wire harness and it
required 244 work hours to complete the replacement. UPS also asked
that the cost for parts for the repair be added. UPS stated that it has
sourced the materials and the cost is $1,680 per airplane (or $168 per
transition location).
    We agree to revise the estimated on-condition work-hours. When
issuing a service bulletin, Boeing estimates work-hours under expected
conditions for direct labor only. As operators implement the service
bulletin, they may find the actual work-hours are higher or lower than
estimated. We have updated the Costs of Compliance section of this AD
to reflect between 100 and 244 work-hours. We have also included the
parts cost estimate provided for repairs.

Request To Add Information Notice To Service Information Citation

    FedEx asked that Boeing Alert Service Bulletin MD11-28A150 IN 02,
dated February 24, 2017, be added to the service information cited in
paragraph (g) of the proposed AD. FedEx stated that the one-time
inspection and corrective actions in paragraph (g) specify performing a
detailed inspection in accordance with the Accomplishment Instructions
of Boeing Alert Service Bulletin MD11-28A150, dated October 6, 2016.
FedEx added that since the referenced service information was issued,
Boeing released an information notice (IN 02) with part numbers for
three new wire assembly kits.
    We disagree with the commenter's request. Boeing Alert Service
Bulletin MD11-28A150 IN 02, dated February 24, 2017, provides updated
kit information for the operators. The individual wire assembly part
numbers in the new kits are the same wire assembly part numbers needed
for the replacement required by this AD as specified in the figures in
Part 3 of the Accomplishment Instructions of Boeing Alert Service
Bulletin MD11-28A150, dated October 6, 2016. Since this AD only
requires the replacement of certain individual wire assembly part
numbers and not the kit part numbers that consist of the individual
wire assembly part numbers, we have made no change to this AD in this
regard.

Request To Clarify Paragraph (h) of the Proposed AD

    FedEx and UPS requested that we clarify the actions specified in
paragraph (h) of the proposed AD. FedEx stated that paragraph (h) of
the proposed AD provides information to perform different tests than
those listed in steps 1.f, 1.g., and 1.h. of Part 4 of the
Accomplishment Instructions of Boeing Alert Service Bulletin MD11-
28A150, dated October 6, 2016. FedEx stated it is not clear if the
required test after rework is in accordance with steps 1.a. through
1.j. of Part 4 of Boeing Alert Service Bulletin MD11-28A150, dated
October 6, 2016, or per the actions specified in (h)(1), (h)(2), and
(h)(3) of this AD only. FedEx and UPS also stated that the proposed AD
should require test procedures only for the section that Boeing Alert
Service Bulletin MD11-28A150, dated October 6, 2016, is addressing and
not all the systems associated with wire assemblies AJS9013 and
AJS9014. FedEx and UPS also noted that the airplane maintenance manual
(AMM) references in paragraphs (h)(1) and (h)(2) of the proposed AD are
incorrect (AMM 28-28-01 should be AMM 28-08-01; AMM 26-21-02 should be
AMM 28-21-02).
    We agree to clarify which actions are required by this AD. Steps
1.f, 1.g., and 1.h. of Part 4 of the Accomplishment Instructions of
Boeing Alert Service Bulletin MD11-28A150, dated October 6, 2016, are
required for compliance (RC) after any rework is done and only address
the system affected by this AD. The other steps identified as ``RC
exempt'' as specified in Part 4 of the Accomplishment Instructions of
Boeing Alert Service Bulletin MD11-28A150, dated October 6, 2016, are
not a part of the requirements of this AD.
    The intent of paragraph (h) of the proposed AD was to specify the
corrective action for RC tests. Steps 1.f, 1.g., and 1.h. of Part 4 of
the Accomplishment Instructions of Boeing Alert Service Bulletin MD11-
28A150, dated October 6, 2016, specify to accomplish tests but the
steps do not specify corrective actions if the tests fail. To clarify
that the tests themselves are not exceptions to Boeing Alert Service
Bulletin MD11-28A150, dated October 6, 2016, we have removed paragraph
(h) of the proposed AD and included the corrective action statement for
the tests in paragraph (g) of this AD.
    We acknowledge that the AMM references in paragraphs (h)(1) and
(h)(2) of the proposed AD were incorrect and note that the AMM
references for the tests are identified correctly in Boeing Alert
Service Bulletin MD11-28A150, dated October 6, 2016.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule with the changes described previously and minor
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and

     Do not add any additional burden upon the public than was
already proposed in the NPRM.
    We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin MD11-28A150, dated
October 6, 2016. The service information describes procedures for a
one-time detailed inspection of the wire assemblies of the tail fuel
tank transfer pumps to determine if metallic transitions are installed
at the wire harness breakouts, and corrective actions that include
repair and replacement of the wire assembly. This service information
is reasonably available because the interested parties have access to
it through their normal course of business or by the means identified
in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 110 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per       Cost on U.S.
              Action                        Labor cost            Parts cost        product         operators

                                     hour = $340.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs/
replacements that will be required based on the results of the
inspection. We have no way of determining the number of aircraft that
might need these repairs/replacements:

                                               On-condition Costs

                                     hour = $765.
Replacement.......................  Between 100 and 244 work-   $57,526..............  Between $66,026 and
                                     hours x $85 per hour =                             $78,266.
                                     between $8,500 and
                                     $20,740.
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
    This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.

Regulatory Findings

    This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect 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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

Background

    The FAA has received a report indicating cracks found on end
stringers of two Model 747-8 airplanes at station (STA) 2285, left and
right sides, during foreign object debris (FOD) inspections in
preparation for airplane modification. Boeing has also reported similar
cracking on other Model 747-8 airplanes. The cracks were not visually
detectable until the stringer splice assemblies were removed. The root
cause was found to be stress corrosion cracking caused by excessive and
sustained internal tensile stresses that were due to no shim being
installed or shimmed gaps exceeding engineering limits at production. A
crack in a stringer or end stringer splice assembly could grow in
length and go undetected. This condition, if not addressed, could
result in the inability of a structural element to sustain limit load
and could adversely affect the structural integrity of the airplane.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or

develop on other products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 747-53A2909 RB,
dated September 21, 2022. This service information specifies procedures
for repetitive detailed inspections of the stringers and the end
stringer splice assemblies at stringers S-17 to S-25 from STA 2285 to
STA 2300 main entry door #5 cutout aft edge frame for any crack, any
shim between a stringer and bear strap, and any gap within the
fastener-joint-to-bear-strap joint, and applicable on-condition
actions. On-condition actions include detailed inspections of the
stringers and end stringers splice assemblies located between STA 2285
and STA 2300 from stringers S-17L to S-25L/S-17R to S-25R, open hole
high frequency eddy current (HFEC) inspection of the fastener holes of
the skin common to the end stringer splice fitting for cracks, and
repair of cracked stringer/end stringer splice fittings.
    This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in ADDRESSES.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified
in the service information already described except for any differences
identified as exceptions in the regulatory text of this proposed AD.
For information on the procedures and compliance times, see this
service information at regulations.gov by searching for and locating
Docket No. FAA-2023-0157.

Clarification of Terminating Action

    Boeing Alert Requirements Bulletin 747-53A2909 RB, dated September
21, 2022, contains a terminating action flagnote (b) in Tables 1
through 4 of the Accomplishment Instructions that specifies ``Doing the
detailed and High Frequency Eddy Current (HFEC) inspections and finding
no crack as a result of the inspection is terminating action to
Requirements Bulletin 747-53A2909 RB for that affected end stringer
splice assembly.'' However, the flagnote ``(b)'' is located with
certain conditions in Tables 1 through 4 and appears to be
contradictory in certain locations, e.g., ``Condition 8.2: No crack
found as a result of option 2 inspections'' specifies to do repetitive
inspections; however the option 2 inspections are the detailed and HFEC
inspections, which the flagnote specifies is terminating action. The
FAA has clarified the terminating action in paragraphs (g)(1) through
(4) of this proposed AD to confirm that no action is required for an
end stringer splice assembly on which no cracking is found after the
specified option 2 inspections are done.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 2 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:

                                                 Estimated Costs

----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of the
proposed inspection. The agency has no way of determining the number of
aircraft that might need these on-condition actions:

                                               On-Condition Costs

----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect 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.
    For the reasons discussed above, I certify this proposed
regulation:

    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

Airworthiness Directives; CFM International, S.A. Turbofan
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain CFM International, S.A. (CFM) LEAP-1B model turbofan engines.
This AD was prompted by multiple commanded in-flight shutdowns (IFSDs)
due to inner radial drive shaft (RDS) failure. This AD requires initial
and repetitive inspections of the transfer gearbox (TGB) scavenge
screens and, depending on the results of the inspections, replacement
or rework of the affected inner RDS. As a mandatory terminating action
to the initial and repetitive inspections of the TGB scavenge screens,
this AD requires replacement or rework of the affected inner RDS. This
AD also prohibits the installation of an engine with an affected inner
RDS onto an airplane that already has one engine with an affected inner
RDS installed. The FAA is issuing this AD to address the unsafe
condition on these products.

DATES: This AD is effective October 20, 2022.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 20,
2022.

ADDRESSES: For service information identified in this final rule,

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain CFM LEAP-1B21,
LEAP-1B23, LEAP-1B25, LEAP-1B27, LEAP-1B28, LEAP-1B28B1, LEAP-1B28B2,
LEAP-1B28B2C, LEAP-1B28B3, LEAP-1B28BBJ1, and LEAP-1B28BBJ2 (LEAP-1B)
model turbofan engines. The NPRM published in the Federal Register on
June 06, 2022 (87 FR 34221). The NPRM was prompted by reports of
multiple IFSDs on CFM LEAP-1B model turbofan engines beginning in
August 2018. The manufacturer's investigations determined that some of
these IFSD events were the result of inadequate oil flow to the RDS
bearing, which caused the RDS bearing and RDS bearing cage to fail. The
FAA issued AD 2019-12-01, Amendment 39-19656 (84 FR 28202, June 18,
2019), which required initial and repetitive inspections of the TGB
scavenge screens and, depending on the results of the inspection,
possible removal of the engine from service.
    After the FAA issued AD 2019-12-01, further investigation by the
manufacturer identified an additional contributing factor to the RDS
bearing failures. The manufacturer revised the service information to
include a repetitive TGB screen inspection until the RDS accumulates
1,500 flight hours (FHs) since new and borescope inspections of the RDS
bearing at 1,500 FHs since new and 6,000 FHs since new. The FAA
superseded AD 2019-12-01 by issuing AD 2020-06-01, Amendment 39-21103
(85 FR 14413, March 12, 2020), which requires revision to the
airworthiness limitations section (ALS) of the applicable engine shop
manual to incorporate the new inspections.
    Since the FAA issued AD 2020-06-01, the FAA received further
reports of commanded IFSDs due to inner RDS failure. The manufacturer
initiated an investigation and identified a subpopulation of inner RDS
susceptible to rivet fatigue failure occurring after the inspection
thresholds required by the ALS revision in AD 2020-06-01. In the NPRM,
the FAA proposed to require initial and repetitive inspections of the
TGB1 and TGB2 scavenge screens and, depending on the results of the
inspections, replacement or rework of the affected inner RDS. As a
mandatory terminating action to the initial and repetitive inspections
of the TGB1 and TGB2 scavenge screens, the FAA proposed to require
replacement or rework of the affected inner RDS. The FAA also proposed
prohibiting the installation of an engine with an affected inner RDS
onto an airplane that already has one engine with an affected inner RDS
installed. The FAA is issuing this AD to address the unsafe condition
on these products.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from three commenters. Commenters
included The Boeing Company, Air Line Pilots Association,
International, and United Airlines. All commenters supported the NPRM
without change.

Conclusion

    The FAA reviewed the relevant data, considered the comments
received, and determined that air safety requires adopting the AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. Except for minor editorial changes, this
AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed CFM Service Bulletin (SB) LEAP-1B-72-00-0258-01A-
930A-C, Issue 002, dated September 15, 2020. This service

information specifies procedures for replacement or rework of the inner
RDS. The FAA also reviewed CFM SB LEAP-1B-72-00-0365-01A-930A-D, Issue
003-00, dated April 26, 2022. This service information identifies the
affected serial numbers of the inner RDS susceptible to rivet fatigue
failure and specifies procedures for performing inspections of TGB1 and
TGB2 scavenge screens. This service information also specifies
procedures for accomplishing applicable corrective actions if metallic
particles are found. This service information is reasonably available
because the interested parties have access to it through their normal
course of business or by the means identified in ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 34 engines installed on
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs

    For either replacement or rework of the inner RDS, depending on the
option selected by the operator to comply with this AD, the FAA
estimates the following costs:

----------------------------------------------------------------------------------------------------------------
                                                                                Cost per

I. Summary of Proposed Action

    On July 27, 2023, the EPA proposed to approve a revision to the
California SIP concerning transportation conformity procedures for the
San Francisco Bay Area.\1\ The California Air Resources Board (CARB)
submitted ``The San Francisco Bay Area Transportation Air Quality
Conformity Protocol--Conformity Procedures'' and ``The San Francisco
Bay Area Transportation Air Quality Conformity Protocol--Interagency
Consultation Procedures,'' on May 17, 2021. We refer to these documents
together as the ``San Francisco Bay Area conformity SIP submittal.''
\2\ CARB submitted a prior version of the San Francisco Bay Area
conformity SIP to the EPA for approval on December 20, 2006. The EPA
approved this SIP revision on October 12, 2007.\3\ The agencies
responsible for developing and updating the San Francisco Bay Area
conformity SIP--the Metropolitan Transportation Commission (MTC), the
Bay Area Air Quality Management District (BAAQMD), and the Association
of Bay Area Governments (ABAG), in consultation with the Sacramento
Area Council of Governments (SACOG)--have since further amended the
roles and responsibilities for implementing the transportation
conformity interagency consultation process and for coordinating travel
activity data sharing. The San Francisco Bay Area conformity SIP
submittal also reflects an update to a memorandum of understanding that
exists between MTC and SACOG as an agreement regarding federal
conformity procedures and programming of federal Congestion Mitigation
and Air Quality funds in Solano County.\4\
---------------------------------------------------------------------------

    \1\ 88 FR 48406 (July 27, 2023).
    \2\ In addition to other supporting documents, the submittal
package included the following documents: ``San Francisco Bay Area
Transportation Air Quality Conformity Protocol,'' Revised: February
26, 2020; ``Amended and Restated Memorandum of Understanding Between
the Metropolitan Transportation Commission and the Sacramento Area
Council of Governments,'' (September 11, 2018); and a letter dated
May 6, 2021, (submitted electronically May 17, 2021), from Richard
W. Corey, Executive Officer, CARB, to Deborah Jordan, Acting
Regional Administrator, EPA Region IX, Subject: San Francisco Bay
Area State Implementation Plan Amended Transportation Air Quality
Conformity Protocol. These documents are available in the docket for
this rulemaking.
    \3\ 72 FR 58013 (October 12, 2007).
    \4\ See ``Metropolitan Transportation Commission Resolution No.
2611. Revised, MTC/Sacramento Area Council of Governments (SACOG)
Memorandum of Understanding (MOU) for Air Quality Planning in
Eastern Solano County'' and Metropolitan Transportation Commission
Resolution No. 3757, ``Re: Approval of San Francisco Bay Area
Transportation Air Quality Conformity Protocol,'' which is included
in the docket for this rulemaking.
---------------------------------------------------------------------------

    In our proposal, we evaluated the San Francisco Bay Area conformity
SIP submittal against the statutory and regulatory requirements of the
CAA, 40 CFR part 93, and 40 CFR 51.390, which govern state procedures
for transportation conformity and interagency consultation and
concluded that the submittal meets these requirements. Furthermore, the
comment period and public hearing held by MTC for this SIP revision
satisfy the requirements of CAA section 110(l) and 40 CFR 51.102. A
technical support document (TSD) is included in the docket for this
rulemaking. Specifically, in our TSD, we identify how the submitted
procedures satisfy requirements under 40 CFR 93.105 for interagency
consultation with respect to the development of transportation plans
and programs, SIPs, conformity determinations, the resolution of
conflicts, the provision of adequate public consultation, and our
requirements under 40 CFR 93.122(a)(4)(ii) and 93.125(c) for
enforceability of control measures and mitigation measures. Please
refer to our TSD and notice of proposed rulemaking for additional
information regarding the content of the revised San Francisco Bay
conformity SIP submittal and our review.

II. Public Comments and EPA Responses

    The 30-day public comment period for the notice of proposed
rulemaking closed on August 28, 2023. During this period, a member of
the public submitted two identical comments to the EPA in support of
the proposed approval. The full text of these comments is available for
viewing in the docket for this rulemaking.

III. EPA Action

    In accordance with section 110(k)(3) of the Act, and for the
reasons discussed in our proposed rulemaking and summarized in this
document, we are finalizing our approval of the San Francisco Bay Area
conformity SIP submittal as a revision to the California SIP. The
revision will be incorporated

into the San Francisco Bay Area portion of the California SIP and
thereby replace the previous revision approved on October 12, 2007.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, the EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves state law as meeting 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 Clean Air Act.
    In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where the EPA or an Indian tribe
has demonstrated that a tribe has jurisdiction. In those areas of
Indian country, this rulemaking does not have tribal implications and
will not impose substantial direct costs on tribal governments or
preempt tribal law as specified by Executive Order 13175 (65 FR 67249,
November 9, 2000).
    Executive Order 12898 (Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
Feb. 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
The EPA defines environmental justice (EJ) as ``the fair treatment and
meaningful involvement of all people regardless of race, color,
national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' The EPA further defines the term fair treatment to mean
that ``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
    The State did not evaluate environmental justice considerations as
part of its SIP submittal; the CAA and applicable implementing
regulations neither prohibit nor require such an evaluation. The EPA
did not perform an EJ analysis and did not consider EJ in this action.
If finalized, this action is expected to have a neutral to positive
impact on the air quality of the affected area. Consideration of EJ is
not required as part of this action, and there is no information in the
record inconsistent with the stated goal of E.O. 12898 of achieving
environmental justice for people of color, low-income populations, and
Indigenous peoples.
    This action is subject to the Congressional Review Act, and the 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 Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by February 26, 2024. 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).)
