SUMMARY: EPA is proposing to approve a revision to the maintenance plan

area. The Cincinnati-Hamilton area includes Butler, Clermont, Clinton, 
Hamilton, and Warren Counties in Ohio, Lawrenceburg Township in 
Dearborn County, Indiana, and Boone, Campbell, and Kenton Counties in 
Kentucky. The Ohio Environmental Protection Agency (Ohio EPA) submitted 
a maintenance plan revision on July 6, 2010. The submittal contained 
revisions to 2015 and 2020 NOX point source emissions 
projections for Butler County to reflect modifications at a major 
source that will occur during the maintenance period.

DATES: Comments must be received on or before December 29, 2010.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the maintenance plan revision 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 adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse 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direct final rule will be withdrawn and all public comments received 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 15, 2010.
