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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
