40 CFR Part 52

[EPA-R05-OAR-2011-0017; EPA-R05-OAR-2011-0106; FRL-9480-7]

Approval and Promulgation of Air Quality Implementation Plans; 
Ohio and Indiana; Redesignation of the Cincinnati-Hamilton Area to 
Attainment of the 1997 Annual Standard for Fine Particulate Matter

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: 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

[[Page 64881]]

Dearborn 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.

SUPPLEMENTARY INFORMATION: 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.

    Dated: October 7, 2011.
