SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal
Register, EPA is approving the State's SIP submittal as a direct final
rule without prior proposal because the Agency views this as a
noncontroversial submittal and anticipates no adverse comments. A
detailed rationale for the approval is set forth in the direct final
rule. If no relevant adverse comments are received in response to this
rule, no further activity is contemplated. If EPA receives such
comments, the direct final rule will be withdrawn and all public
comments received will be addressed in a subsequent final rule based on
this proposed rule. EPA will not institute a second comment period. Any
parties interested in commenting on this action should do so at this
time. Please note that if EPA receives adverse comment on an amendment,
paragraph, or section of this rule and if that provision may be severed
from the remainder of the rule, EPA may adopt as final those provisions
of the rule that are not the subject of an adverse comment. For
additional information, see the direct final rule which is located in
the Rules section of this Federal Register.
Dated: November 14, 2025.
Cheryl Newton,
Acting Regional Administrator, Region 5.
