Approval and Promulgation of Air Quality Implementation Plans;

Hour Ozone Maintenance Plan Revisions to Approved Motor Vehicle 
Emissions Budgets

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve the request by Ohio and Indiana to 
revise the Cincinnati-Hamilton, 1997 8-hour ozone maintenance air 
quality State Implementation Plans (SIPs) to replace the previously 
approved motor vehicle emissions budgets (budgets) with budgets 
developed using EPA's Motor Vehicle Emissions Simulator (MOVES) 2010a 
emissions model. The Ohio and Indiana portions of the Cincinnati-
Hamilton area include the Ohio Counties of Butler, Clermont, Clinton, 
Hamilton, and Warren, Ohio and Lawrenceburg Township in Dearborn 
County, Indiana. Ohio submitted the SIP revision request to EPA on June 
29, 2012. Indiana submitted the SIP revision request to EPA for 
parallel processing with a letter dated October 12, 2012, and followed 
up with a final submittal on December 11, 2012. Ohio and Indiana have 
submitted identical budgets which cover the Ohio and Indiana portions 
of the Cincinnati-Hamilton 1997 ozone maintenance area.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the states' SIP submittals 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direct final rule will be withdrawn and all public comments received 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: January 11, 2013.
