Environmental Protection Agency (EPA).
EPA is proposing to approve Ohio's and Indiana's requests to redesignate their respective portions of the Cincinnati-Hamilton OH-IN-KY nonattainment area (for Ohio: Butler, Clermont, Hamilton, and Warren Counties, Ohio; for IN: a portion of Start Printed Page 64881Dearborn County) to attainment for the 1997 annual National Ambient Air Quality Standard (NAAQS or standard) for fine particulate matter (PM2.5). The Ohio Environmental Protection Agency (Ohio EPA) submitted its request on December 9, 2010, and the Indiana Department of Environmental Management (IDEM) submitted its request on January 25, 2011. Kentucky's request to redesignate its portion of the Cincinnati-Hamilton area, submitted to EPA to on January 27, 2011, will be addressed in a separate rulemaking action. EPA's proposal here involves several additional related actions. EPA has previously determined that the entire Cincinnati-Hamilton (OH-IN-KY) area has attained the 1997 annual PM2.5 standard. EPA is proposing to approve, as revisions to the Ohio and Indiana State Implementation Plans (SIPs), the States' plans for maintaining the 1997 annual PM2.5 NAAQS through 2021 in the area. EPA is proposing to approve the 2005 emissions inventories for the Ohio and Indiana portions of the Cincinnati-Hamilton area as meeting the comprehensive emissions inventory requirement of the Clean Air Act (CAA). Finally, EPA finds adequate and is proposing to approve Ohio and Indiana's Nitrogen Oxides (NOX) and PM2.5 Motor Vehicle Emission Budgets (MVEBs) for 2015 and 2021 for the Cincinnati-Hamilton area.

In the Final Rules section of this Federal Register, EPA is approving the determination of attainment, redesignation, and SIP as a direct final rule without prior proposal because the Agency views this as a noncontroversial action 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.Start Signature
