Abstract
The Environmental Protection Agency (EPA) is proposing to approve Missouri State Implementation Plan (SIP) revisions submitted on November 10, 2020, by the Missouri Department of Natural Resources (MoDNR). This proposed action will amend the SIP to address administrative changes to the State rule in the Missouri Code of State Regulations (CSR). Revisions include removal of references to a revoked state regulation and other minor administrative changes. The EPA is proposing to approve these changes because they are consistent with the Clean Air Act (CAA) and applicable EPA regulations. In the "Rules and Regulations" section of this Federal Register, we are approving the State's SIP revisions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve Missouri State Implementation Plan (SIP) revisions submitted on
November 10, 2020, by the Missouri Department of Natural Resources
(MoDNR). This proposed action will amend the SIP to address
administrative changes to the State rule in the Missouri Code of State
Regulations (CSR). Revisions include removal of references to a revoked
state regulation and other minor administrative changes. The EPA is
proposing to approve these changes because they are consistent with the
Clean Air Act (CAA) and applicable EPA regulations. In the ``Rules and
Regulations'' section of this Federal Register, we are approving the
State's SIP revisions as a direct final rule without a prior proposed
rule. If we receive no adverse comment, we will not take further action
on this proposed rule.
DATES: Comments must be received by May 11, 2026.

SUPPLEMENTARY INFORMATION: This document proposes to take action on
changes to the State rule at Title 10, Division 10 of the Code of State
Regulations (CSR) 5.570, Control of Sulfur Emissions From Stationary
Boilers, as revisions to the SIP previously approved at 40 CFR
52.1320(c). Revisions include removal of references to a revoked State
regulation and other minor administrative changes. We have published a
direct final rule approving the State's SIP revision in the ``Rules and
Regulations'' section of this Federal Register, because we view this as
a noncontroversial action and anticipate no relevant adverse comment.
We have explained our reasons for this action in the preamble to the
direct final rule. If we receive no adverse comment, we will not take
further action on this proposed rule. If we receive adverse comment, we
will withdraw the direct final rule and it will not take effect. We
would address all public comments in any subsequent final rule based on
this proposed rule. We do not intend to institute a second comment
period on this action. Any parties interested in commenting must do so
at this time. For further information, please see the information
provided in the ADDRESSES section of this document.
