Abstract
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) related to the control of emissions during petroleum liquid storage, loading and transfer in the St. Louis area. The revisions to this rule include revising the tank size threshold applicability of the rule, adding incorporations by reference to other state rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, adding a streamlined process for modifications to vapor recovery systems at gasoline dispensing facilities and thereby eliminating the associated permitting requirement, and clarifying rule language on testing and reporting. The revisions make this provision consistent with a similar rule that is applicable to the Kansas City area and regulates the same type of facilities. These revisions do not interfere with the State's ability to attain or maintain the National Ambient Air Quality Standards (NAAQS). The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve revisions to the Missouri State Implementation Plan (SIP)
related to the control of emissions during petroleum liquid storage,
loading and transfer in the St. Louis area. The revisions to this rule
include revising the tank size threshold applicability of the rule,
adding incorporations by reference to other state rules, adding
definitions specific to the rule, revising unnecessarily restrictive or
duplicative language, adding a streamlined process for modifications to
vapor recovery systems at gasoline dispensing facilities and thereby
eliminating the associated permitting requirement, and clarifying rule
language on testing and reporting. The revisions make this provision
consistent with a similar rule that is applicable to the Kansas City
area and regulates the same type of facilities. These revisions do not
interfere with the State's ability to attain or maintain the National
Ambient Air Quality Standards (NAAQS). The EPA's proposed approval of
this rule revision is being done in accordance with the requirements of
the Clean Air Act (CAA).

II. What is being addressed in this document?
The EPA is proposing to approve a SIP revision submitted by the
State of Missouri on March 7, 2019, and supplemented on August 1, 2019.
The revisions are to Title 10, Division 10 of the Code of State
Regulations (CSR), 5.220 ``Control of Emissions During Petroleum Liquid
Storage, Loading and Transfer''. The purpose of the state regulation is
to restrict volatile organic compound (VOC) emissions from the handling
of petroleum liquids to reduce hydrocarbon emissions in the St. Louis
metropolitan area that contribute to the formation of ozone. Missouri
made multiple revisions to the rule. These revisions change the
applicability threshold of the smaller tank size subject to the rule
from 500-1,000 gallon tanks to 550-1,000 gallon tanks, eliminate the
permitting requirement by adding a streamlined procedural process for
modifications to vapor recovery systems at gasoline dispensing
facilities, clarify rule language on testing and reporting, update
incorporations by reference to other state rules, add definitions
specific to the rule, revise unnecessarily restrictive or duplicative
language, and make administrative structure and wording changes. The
EPA proposes to find that these revisions meet the requirements of the
CAA and do not interfere with the State's ability to attain or maintain
the NAAQS. The full text of the rule revisions as well as EPA's
analysis of the revisions can be found in the technical support
document (TSD) included in this docket.
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 August 1, 2018,
to October 4, 2018, and held a public hearing on September 27, 2018.
Missouri received twenty-nine (29) comments from seven sources during
the comment period on 10 CSR 10-5.220. The EPA provided three comments.
Missouri included additional clarification to EPA by submitting
supplemental information on August 1, 2019, to clarify and answer
questions EPA made during the comment period. Missouri responded to all
comments and revised the rule based on some of the public comments
made, as noted in the State submission included in the docket for this
action. As explained above and in more detail in the technical support
document, which is part of this docket, the revision meets the
substantive SIP requirements of the CAA, including section 110 and
implementing regulations.
IV. What action is the EPA taking?
The EPA is proposing to amend the Missouri SIP by approving the
State's request to revise 10 CSR 10-5.220 ``Control of Emissions During
Petroleum Liquid Storage, Loading and Transfer.'' 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. 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
finalize the incorporation by reference of the Missouri rule 10 CSR 10-
5.220 discussed in section II. of this preamble and as set forth below
in the proposed amendments to 40 CFR part 52. The purpose of this state
regulation is to restrict VOC emissions from the handling of petroleum
liquids to reduce hydrocarbon emissions in the St. Louis metropolitan
area that contribute to the formation of ozone. The EPA has made, and
will continue to make, these materials generally available through
<a href="https://www.regulations.gov">https://www.regulations.gov</a> 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).
VI. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, 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:
<bullet> Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Order 12866 (58
FR 51735, October 4, 1993);
<bullet> Is not subject to Executive Order 14192 (90 FR 9065,
February 6, 2025) because SIP actions are exempt from review under
Executive Order 12866:
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> 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.);
<bullet> 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);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it approves a state program;
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> 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 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).
