Air Plan Approval; Approval of Missouri Air Quality
Implementation Plans; Revisions to St. Louis 1997 PM2.5 Maintenance
Plan
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a State Implementation Plan (SIP) revision submitted by the
State of Missouri on November 12, 2019, revising the maintenance plan
demonstrating continued maintenance of the 1997 PM2.5
National Ambient Air Quality Standards (NAAQS) in the St. Louis area.
This revision states that the St. Louis area no longer needs to rely on
the vehicle Inspection and Maintenance (I/M) program and the use of
Reformulated Gasoline (RFG) for continued maintenance throughout the
maintenance period for the 1997 PM2.5 NAAQS. EPA is
proposing to determine that this revision meets the requirements of the
Clean Air Act.

II. What is being addressed in this document?
The EPA is proposing to approve SIP revisions submitted by the
State of Missouri on November 12, 2019, revising the 1997
PM2.5 maintenance plan. This SIP revision demonstrates
continued maintenance of the 1997 PM2.5 NAAQS in the St.
Louis area through the future year of 2025. The maintenance area
boundary includes the Missouri counties of Franklin, Jefferson, St.
Charles, and St. Louis along with the City of St. Louis.
Through this action, the Missouri Department of Natural Resources
(MoDNR) is requesting EPA to approve
[[Page 40396]]
this maintenance plan into Missouri's SIP pursuant to Clean Air Act
(CAA) Section 175A as a replacement to the maintenance plan previously
approved by EPA on October 2, 2018 (83 FR 38033).
On August 3, 2018, EPA published in the Federal Register a final
rulemaking approving the State of Missouri's request to redesignate the
Missouri portion of the St. Louis nonattainment area to attainment and
their demonstration for maintaining the 1997 PM2.5 NAAQS
through the ten-year maintenance period. The effective date for this
approval was on October 2, 2018 (83 FR 38033).
The SIP revision we are acting on in this proposal, removes the
reliance on the St. Louis vehicle Inspection and Maintenance (I/M)
program and the use of Reformulated Gasoline (RFG) for continued
maintenance of the 1997 PM2.5 standard. To support this
revision, Missouri utilized EPA's 2014 Motor Vehicle Emissions
Simulator (MOVES2014b) emission modeling system to project revised
mobile source emissions by removing emissions reductions related to I/M
and RFG throughout the maintenance period to the future year of 2025.
Tables 1 and 2 below lists the total direct PM2.5 and
PM2.5 precursor emissions for the attainment year 2008 and
the projection year 2025 for point, area, onroad and nonroad source
categories of the five counties in the St. Louis area. Because the area
attained the standard in 2008, this represents a level of emissions
suitable to maintain compliance with the 1997 PM2.5
standard. By comparing the total emissions in Tables 1 and 2,
Missouri's emissions analysis shows substantial decreases in mobile
source emissions and decreases in total source category emissions
through the maintenance period of 2025. These decreases in direct
PM2.5 and precursor pollutants demonstrate the area will
continue to meet the 1997 PM2.5 standard throughout the
maintenance period without relying on the I/M program or RFG
requirements in the Missouri portion of the maintenance area.

It is important to note approval of this maintenance plan revision
does not remove the I/M program or the RFG program requirements from
the SIP.
In addition, the motor vehicle emissions budgets (MVEBs) from the
previously SIP approved Maintenance Plan for the PM2.5 NAAQS
\1\ and this SIP submittal remain the same. Therefore, there are no new
MVEBs being created for this SIP revision. Moreover, EPA has revoked
the 1997 primary annual PM2.5 NAAQS, which has been replaced
by the more health protective 2012 primary annual PM2.5
NAAQS and Missouri is currently in compliance with this standard (84 FR
36472). As a result, areas that have been redesignated to attainment
for the 1997 annual PM2.5 NAAQS (i.e., maintenance areas for
the 1997 annual PM2.5 NAAQS) will no longer be required to
make transportation conformity determinations for that NAAQS (81 FR
58010).
---------------------------------------------------------------------------
\1\ 83 FR 38033, August 3, 2018 (effective date of October 2,
2018).
---------------------------------------------------------------------------
EPA is proposing approval of the revised maintenance plan based on
information provided in the emissions projections, modeling results and
an evaluation of quality assured air monitoring data submitted as part
of this revision and in a previously reviewed analysis as part of the
St. Louis Nonattainment Area 1997 PM2.5 NAAQS Redesignation
rulemaking published on August 3, 2018 (83 FR 38033). Current and
future projections of air quality and emissions data for this revision
demonstrates maintenance for the 1997 PM2.5 NAAQS.
This revision only affects maintenance for the 1997
PM2.5 standard, only removes the reliance upon the I/M and
RFG programs for continued maintenance and therefore meets the
requirements of the Clean Air Act.
The full text of the plan revisions including Missouri's technical
[[Page 40397]]
demonstration can be found in the State's submission, which is included
in the docket for this action.
III. Have the requirements for approval of a SIP revision been met?
The State submission has 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 this SIP revision from July 29, 2019
through September 13, 2019 and received one comment from the Missouri
Petroleum Marketers and Convenience Store Association, one comment from
Abel Realty, and thirteen comments from EPA. After receiving comments,
the state revised the SIP prior to submitting the plan to EPA. In
addition, as explained above and in more detail in the Missouri
submittal document, which is part of the docket, the revision meets the
substantive SIP requirements of the CAA, including section 110 and
implementing regulations.
IV. What action is the EPA proposing to take?
We are proposing to approve a SIP revision submitted by the State
of Missouri on November 12, 2019, revising the 1997 PM2.5
maintenance plan. EPA is proposing to determine that this revision
would not interfere with attainment or maintenance of the NAAQS or with
any other CAA requirement. We are processing this as a proposed action
because we are soliciting comments on this proposed action. Final
rulemaking will occur after consideration of any comments.
V. Statutory and Executive Order Reviews
Under the Clean Air Act (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
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
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 proposed
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).
