40 CFR Part 52
[EPA-R07-OAR-2022-0419; FRL-9830-01-R7]
Air Plan Approval; Missouri; St. Louis Area Vehicle Inspection
and Maintenance Program
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve, through parallel processing, revisions to the Missouri State
Implementation Plan (SIP) relating to the St. Louis area's vehicle
Inspection and Maintenance (I/M) Program received on November 12, 2019,
and March 2, 2022. In the submissions, Missouri requests EPA approval
of revisions to a regulation and related plan that implement the St.
Louis area's Inspection and Maintenance program called, Gateway Vehicle
Inspection Program (GVIP). We propose to approve Missouri's removal of
vehicles registered in Franklin County, unless the vehicle is primarily
operated in the rest of the area, from the Gateway Vehicle Inspection
program. The revisions to this rule include amending the rule exemption
section for vehicles subject to the rule, removing unnecessary words,
amending definitions specific to the rule, updates due to technology
changes, and other minor edits. These revisions do not impact the
attainment of any National Ambient Air Quality Standard (NAAQS) nor
delay the timely attainment of 2015
[[Page 30438]]
Ozone National Ambient Air Quality Standard. Approval of these
revisions will ensure consistency between state and federally approved
rules.
DATES: Comments must be received on or before June 21, 2022.
ADDRESSES: You may send comments, identified by Docket ID No. EPA-R07-
OAR-2022-0419 to https://www.regulations.gov. Follow the online

I. Written Comments
Submit your comments, identified by Docket ID No. EPA-R07-OAR-2022-
0419, at https://www.regulations.gov. Once submitted, comments cannot
be edited or removed from Regulations.gov. The EPA may publish any
comment received to its public docket. Do not submit electronically any
information you consider to be Confidential Business Information (CBI)
or other information whose disclosure is restricted by statute.
Multimedia submissions (audio, video, etc.) must be accompanied by a
written comment. The written comment is considered the official comment
and should include discussion of all points you wish to make. The EPA
will generally not consider comments or comment contents located
outside of the primary submission (i.e., on the web, cloud, or other
file sharing system). For additional submission methods, the full EPA
public comment policy, information about CBI or multimedia submissions,
and general guidance on making effective comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.
II. Parallel Processing
Parallel processing refers to a process that utilizes concurrent
state and federal proposed rulemaking actions, consistent with the
provisions of 40 CFR part 51, appendix V. Generally, the state submits
a copy of the proposed regulation or other revisions to EPA before
conducting its public hearing and completing its public comment process
under state law. EPA reviews this proposed state action and prepares a
notice of proposed rulemaking (NPRM) under federal law.\1\ If, after
the state completes its public comment process and after EPA's public
comment process, the state changes its final submittal from the
proposed submittal, EPA evaluates those changes and decides whether to
publish another NPRM in light of those changes or to proceed to taking
final action on its proposed action and describe the state's changes in
its final rulemaking action. Any final rulemaking action by EPA will
occur only after the final submittal has been adopted by the state and
formally submitted to EPA.
---------------------------------------------------------------------------
\1\ Although not the case in this proposed rulemaking, in some
instances, EPA's NPRM is published in the Federal Register during
the same time frame that the state is holding its public hearing and
conducting its public comment process. The state and EPA then
provide for concurrent public comment periods on both the state
action and federal action.
---------------------------------------------------------------------------
Missouri's November 12, 2019 submittal has been adopted by the
state and formally provided to EPA. Missouri's public comment process
has been completed for its March 2, 2022 submittal, but the
implementing state regulation in the submittal has not been formally
submitted by the state to EPA. In accordance with the parallel
processing provisions in section 2.3.1 of 40 CFR part 51, appendix V,
the State has been provided an opportunity to consider EPA comments
prior to submission of a final plan for EPA's review and has submitted
a schedule for final submittal of the state regulation. Specifically,
Missouri's schedule includes publication of the order of rulemaking in
the Missouri Register on April 15, 2022. The final state regulation was
published in Missouri's Code of State Regulations (CSR) on April 30,
2022 and will become effective 30 days later on May 30, 2022. Missouri
anticipates formally submitting the regulation package to EPA shortly
after the rule's publication in the CSR. Because the State has
satisfied all requirements for parallel processing concerning the March
2, 2022, submittal, EPA proposes to approve the submittal through
parallel processing. If the State changes the final submittal from the
version that we are proposing to approve today, EPA will evaluate the
significance of those changes. If EPA finds any such changes to be
significant, then the Agency intends to determine whether to re-propose
based on the revised submission or proceed to take final action on the
submittal as modified by the State.
III. History and Current Status of St. Louis Area Air Quality
The St. Louis, Missouri-Illinois bi-state area, which has been
designated as nonattainment for several prior Ozone NAAQS, has
historically included the counties of Franklin, Jefferson, St. Charles,
and St. Louis and St. Louis City in Missouri, and the counties of
Madison, Monroe and St. Clair in Illinois (hereafter referred to as the
St. Louis area unless otherwise noted). For all Ozone NAAQS, except for
the 2015 Ozone NAAQS, the St. Louis area has been redesignated to
attainment as described in this section.
On May 12, 2003, EPA redesignated the St. Louis area from Serious
nonattainment to attainment for the 1979 Ozone NAAQS. (68 FR 25418). On
June 15, 2005, EPA revoked the 1979 1-hour Ozone NAAQS for all areas
except the 8-hour Ozone nonattainment early action compact (EAC) areas.
(70 FR 44470). The St. Louis area did not participate in the EAC and
therefore, the 1-hour standard was revoked for all areas in Missouri
effective June 15, 2005.
On February 20, 2015, EPA redesignated the St. Louis area from
Moderate nonattainment to attainment for the 1997 8-hour Ozone NAAQS.
(80 FR 9207). On March 6, 2015, EPA revoked the 1997 8-hour Ozone
NAAQS. (80 FR 12264).
On September 20, 2018, EPA redesignated the St. Louis area from
Moderate nonattainment to attainment for the 2008 8-hour Ozone NAAQS.
(83 FR 47572). The 2008 8-hour Ozone NAAQS has not been revoked.
On April 30, 2018, EPA designated Boles Township of Franklin
County, St. Charles County, St. Louis County, and St. Louis City as
Marginal
[[Page 30439]]
nonattainment for the 2015 Ozone NAAQS. (83 FR 25776) As part of that
same action, EPA designated Jefferson County and the remaining portion
of Franklin County as attainment/unclassifiable. On July 10, 2020, the
District of Columbia Circuit Court remanded the Jefferson County
designation (among other designations) back to the EPA. The Court
upheld EPA's designation of Boles Township as nonattainment and the
remainder of Franklin County as attainment/unclassifiable. In response
to the Court remand, the EPA revised the Jefferson County designation
to nonattainment on May 26, 2021. (86 FR 31438) On November 16, 2017,
EPA designated all areas of Missouri except the St. Louis area as
attainment/unclassifiable for the 2015 8-hour Ozone NAAQS. (82 FR
54232)
On March 29, 1999, EPA redesignated a portion of St. Louis County
and St. Louis City from nonattainment to attainment for the 1971 Carbon
Monoxide (CO) NAAQS. (64 FR 3855).
On August 3, 2018, EPA redesignated Franklin County, Jefferson
County, St. Charles County, St. Louis County, and St. Louis City from
nonattainment to attainment for the 1997 Annual Fine Particulate Matter
(PM2.5) NAAQS. (83 FR 38033).
A portion of Jefferson County is currently designated nonattainment
for both the 2008 and 1978 Lead NAAQS. This nonattainment area is
currently monitoring compliance with both the 1978 and 2008 Lead
NAAQS.\2\ The rest of the St. Louis Area is designated attainment/
unclassifiable for both the 2008 and 1978 Lead NAAQS.
---------------------------------------------------------------------------
\2\ See file titled Herculaneum AQS Report in Docket.
---------------------------------------------------------------------------
On January 28, 2022, EPA redesignated a portion of Jefferson County
from nonattainment to attainment for the 2010 1-hour SO2
NAAQS. (87 FR 4508). The rest of the St. Louis Area is designated as
either attainment or unclassifiable for the 2010 SO2 NAAQS.
The St. Louis Area is designated attainment/unclassifiable for all
other NAAQS.
IV. Background of Missouri's I/M Program
Under section 182 (b)(4),(c), and (d) of the CAA, vehicle I/M
programs are required for areas that are classified as Moderate or
above nonattainment for Ozone. As a result, Missouri has previously
submitted, and the EPA has previously approved into the SIP an I/M
program for the St. Louis Area of Franklin County, Jefferson County,
St. Charles County, St. Louis County, and St. Louis City.\3\ At the
time of the program's inception, the program was based on tailpipe
testing. In 2000, the EPA approved Missouri's switch to On Board
Diagnostic testing for the same geographic area, consistent with our
regulations and section 182 of the CAA.\4\

V. What is being addressed in this document?
The EPA is proposing to approve, through parallel processing,
revisions to the Missouri SIP received on November 12, 2019 and March
2, 2022. In the November 12, 2019, submission, Missouri requested EPA
approval of revisions to the vehicle I/M Program also known as GVIP,
for the St. Louis area. The revisions remove both Franklin and
Jefferson Counties from the GVIP; however, the EPA is only proposing to
take action on the removal of Franklin County from the GVIP in
accordance with a request from Missouri.
At the time of the November 12, 2019 submission, Missouri had not
yet revised the implementing GVIP regulations nor provided supplemental
emission controls to offset the emission increases resulting from
ceasing vehicle emission inspections in the Boles Township portion of
the nonattainment area, in accordance with CAA section 110(l). EPA's
longstanding position is that the implementing rule revision and
supplemental emission controls, for the nonattainment area, are needed
for EPA approval. This position is consistent with the CAA, our
implementing regulations, and our previous approvals of I/M removal
across the nation.
At the time of Missouri's November 12, 2019 submission, Jefferson
County was designated as attainment/unclassifiable for the 2015 Ozone
NAAQS. As a result of the May 26, 2021 EPA designation for Jefferson
County to nonattainment, Missouri requested that EPA act on the removal
of Franklin County from the GVIP plan and postpone action on the
removal of Jefferson County from the GVIP plan via a letter dated
December 6, 2021.\5\ Missouri would need to provide further
supplemental emission controls for us to be able to propose approving
the removal of I/M in Jefferson County as long as the County remains
designated nonattainment. Additionally, in response to comment from EPA
on the draft rulemaking, Missouri limited the implementing regulation's
exemption to Franklin County as opposed to exempting both Franklin and
Jefferson Counties.
---------------------------------------------------------------------------
\5\ Missouri's December 6, 2021 letter to EPA is included in the
docket for this action.
---------------------------------------------------------------------------
On March 2, 2022, Missouri submitted a draft SIP revision
supplementing the November 12, 2019 submittal, along with a parallel
processing request. The March 2, 2022 submittal included both the
revised implementing rule, 10 CSR 10-5.381, and supplemental emission
controls to offset the increased emissions in the Boles Township
portion of Franklin County that is designated as nonattainment for the
2015 Ozone NAAQS. The revision to 10 CSR 10-5.381 adds an exemption for
vehicles registered in Franklin County from the program unless the
vehicles are primarily operated in the remainder of nonattainment area.
The revisions to this rule include amending the rule exemption section
for vehicles subject to the rule, removing unnecessary words, amending
definitions specific to the rule, and other minor edits. The EPA is
proposing to approve the portion of the November 12, 2019 GVIP Plan
relating to Franklin County, St. Charles County, St. Louis County, and
St. Louis City, by approving the removal of Franklin County from the I/
M program, and fully approve the revisions to 10 CSR 10-5.381.
In accordance with Missouri's December 6, 2021, letter, the EPA is
not taking action on Missouri's November 12, 2019 request to remove
Jefferson County from the Inspection and Maintenance Program for the
St. Louis Area. Missouri states in the 2021 letter that it views the
requests in the 2019 SIP revision to remove inspection and maintenance
requirements in Franklin and Jefferson Counties as severable. The EPA
agrees the removal of inspection and maintenance requirements in
Franklin and Jefferson Counties are severable. Missouri also states in
the letter that the implementing regulation, 10 CSR 10-5.381, continues
to require the inspection and maintenance program to operate in
Jefferson County. As a result of today's proposed action, the
nonregulatory 1999 Implementation Plan for the Missouri Inspection and
Maintenance Program, originally approved into the SIP on May 18, 2000,
65 FR 31480, remains approved into the SIP for Jefferson County. The
EPA proposes to approve the nonregulatory Inspection and Maintenance
Program for the St. Louis Area--2019 Revision, into the SIP, which
requires the I/M program to continue to operate in the City of St.
Louis and the counties of St. Louis and St. Charles and removes
requirements for Franklin County.
[[Page 30440]]
The EPA's analysis of the revisions can be found in the ``What is
the EPA's analysis of Missouri's SIP request?'' section and in the
technical support document (TSD) included in this docket.
VI. Have the requirements for approval of a SIP revision been met?
Both the 2019 and 2022 State submissions have met the public notice
requirements for SIP submissions in accordance with 40 CFR 51.102. The
submission also satisfied the completeness criteria of 40 CFR part 51,
appendix V. The State provided public notice on the November 12, 2019
SIP revision from July 29, 2019 to August 29, 2019 and on the March 2,
2022 SIP revision from October 15, 2021 to December 9, 2021. The State
received ten comments during the 2019 public notice. The State received
four comments on the 2021 public notice. The EPA finds Missouri has
adequately addressed the comments received in its submissions. Please
see the TSD for more discussion on Missouri's responses to comments. In
addition, as explained here and in more detail in the TSD which is part
of this docket, the revision meets the substantive SIP requirements of
the Clean Air Act (CAA), including section 110 and implementing
regulations.
VII. What is the EPA's analysis of Missouri's SIP request?
EPA is making the preliminary determination that the Ozone NAAQS is
the primary focus for the noninterference demonstration required by
section 110(l) of the CAA because the I/M program results primarily in
emissions benefits for VOCs, NOX, and CO. While the GVIP
program does produce CO reductions, the St. Louis Area has CO
concentration much less than the CO NAAQS. Ozone concentrations are at
the Ozone NAAQS. As such, any increases to CO emissions are unlikely to
lead to a violation of the CO NAAQS, but any increases to Ozone
precursors are extremely likely to cause a violation of the Ozone
NAAQS. VOCs and NOX emissions are precursors for Ozone.
NOX emissions are precursors for particulate matter.
NO2 is a component of NOX. There are no emissions
reductions attributable to the emissions of particulate matter, lead
and sulfur dioxide (SO2) from the I/M program.
In Missouri's March 2, 2022, SIP revision, the State concluded that
the removal of the Franklin County from the I/M program would not
interfere with attainment or maintenance of the Ozone NAAQS. While
MOVES2014 mobile emissions modeling results show no Ozone precursor
increase from 2017 to 2020 associated with the removal of Franklin
County from the I/M program, MOVES2014 mobile emission modeling results
show Ozone emission precursor increases on a same year comparison. The
Ozone design value in St. Louis is right at the level of the 2015 Ozone
standard. Since Boles Township of Franklin County is part of the St.
Louis nonattainment area and emissions from Boles Township have been
shown to impact air quality in the rest of the St. Louis Area, Missouri
has provided supplemental NOX emission controls exceeding
the amount of the highest same year increase from removal of the I/M
program. Since the rest of Franklin County is attainment/unclassifiable
for the 2015 Ozone NAAQS and emissions from the rest of the county do
not impact the St. Louis Area, Missouri is relying on the 2017 to 2020
emission comparison. The EPA proposes to find that removal of Franklin
County from the SIP-approved I/M program would not interfere with
attainment or maintenance of the 2015 or any prior Ozone NAAQS.
Franklin County is designated attainment or unclassifiable for all
other NAAQS. Missouri's MOVES2014 mobile emission modeling showed no
emission increase for particulate matter, NO2, CO, or lead.
Based on this data together with air quality data, EPA is making the
preliminary determination that the change will not interfere with the
area's ability to maintain the particulate matter, NO2, CO,
or lead NAAQS, or any other applicable requirement. EPA is making the
preliminary determination that the change will not interfere with
reasonable progress towards natural visibility in Missouri's Class I
areas nor any Class I area in another state Missouri impacts. For more
details please see the ``Clean Air Act (CAA) Section 110(l)
Demonstration'' section of the TSD in the docket of this action.
VIII. What action is the EPA proposing to take?
The EPA is proposing to approve, through parallel processing,
revisions to the Missouri SIP received on November 12, 2019 and March
2, 2022. The EPA is proposing to approve portions of the November 12,
2019 GVIP Plan, by approving the removal of Franklin County from the I/
M program, and fully approve the revisions to 10 CSR 10-5.381. The EPA
is not taking action on the remainder of the November 12, 2019 GVIP
Plan, at this time. We are soliciting comments on this proposed action.
Final rulemaking will occur after consideration of any comments.
IX. Environmental Justice Concerns
When the EPA reviews a state's desired change to their SIP for a
NAAQS, the CAA requires the EPA to ensure that the change will not
cause ``backsliding'' of the air quality or delaying attainment of air
quality. SIP revisions address environmental justice concerns by
ensuring that the public is properly informed about the Plan and
regulations to attain and maintain air quality.
The EPA utilized the EJSCREEN tool to evaluate environmental and
demographic indicators within Franklin County, Jefferson County, St.
Charles County, St. Louis County, and St. Louis City. The tool outputs
reports are contained in the docket for this action. Looking
specifically at Franklin County, the EPA's EJSCREEN tool demonstrates
that demographic indicators are consistent with national averages,
however there are vulnerable populations in Franklin County including
low-income populations and persons over 64 years of age. In addition,
emissions from Boles Township impact populations in the other portions
of the nonattainment area. St. Louis City has demographic indicators
significantly above national averages for low-income and minority
populations. While the other counties' demographic indicators are
consistent with or lower than national averages, there are vulnerable
populations in these Counties including low-income populations and
persons over 64 years of age.
CAA section 110 requires Missouri to provide supplemental emission
controls for the increases from Boles Township. As described earlier,
EPA proposes to find these supplemental emission controls are
sufficient to address the projected emissions increase from ceasing
GVIP in Franklin County.
This action addresses EPA's determination that the removal of
Franklin County registered vehicles from the GVIP, unless they are
predominately operated in the rest of the St. Louis Area. This action
proposes to determine the removal of these Franklin County registered
vehicles from the GVIP will not have an adverse impact to air quality
or interfere with the nonattainment area attaining or maintaining the
NAAQS. For these reasons, this proposed action does not result in
disproportionately high and adverse human health or environmental
effects on minority populations, low-income populations and/or
indigenous peoples.
[[Page 30441]]
X. Incorporation by Reference
In this document, the EPA is proposing to include regulatory text
in an EPA final rule that includes incorporation by reference. In
accordance with requirements of 1 CFR 51.5, the EPA is proposing to
incorporate by reference the Missouri 10 CSR 10-5.381 as described in
Sections V and VIII of this preamble and set forth below in the
proposed amendments to 40 CFR part 52. The EPA has made, and will
continue to make, these materials generally available through
www.regulations.gov and at the EPA Region 7 Office (please contact the
person identified in the FOR FURTHER INFORMATION CONTACT section of
this preamble for more information).
XI. 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 CAA. 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 13563 (76 FR 3821, January 21, 2011);
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 an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of the National Technology
Transfer and Advancement Act (NTTA) because this rulemaking does not
involve technical standards; and
This action does not have disproportionately high and
adverse human health or environmental effects on minority populations,
low-income populations and/or indigenous peoples, as specified in
Executive Order 12898 (59 FR 7629, February 16, 1994). The basis for
this determination is contained in section IX of this action,
``Environmental Justice Concerns.''
The SIP is not approved to apply on any Indian reservation land or
in any other area where EPA or an Indian tribe has demonstrated that a
tribe has jurisdiction. In those areas of Indian country, the rule does
not have tribal implications and will not impose substantial direct
costs on tribal governments or preempt tribal law as specified by
Executive Order 13175 (65 FR 67249, November 9, 2000).
