# Air Plan Approval; Ohio; Base Year Emission Inventories for the 2008 8-Hour Ozone Standard
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Proposed rule.
**SUMMARY:**
The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), a State Implementation Plan (SIP) revision submitted by the Ohio Environmental Protection Agency (OEPA) on July 18, 2014, to address emission inventory requirements for the Cleveland-Akron-Loraine, Ohio (OH) and Columbus, OH ozone nonattainment areas and for the Ohio portion of the Cincinnati, Ohio-Kentucky-Indiana ozone nonattainment area under the 2008 ozone national ambient air quality standard. The CAA requires emission inventories for all ozone nonattainment areas. The emission inventories contained in Ohio's July 18, 2014, submission meet this CAA requirement. EPA is also proposing to confirm that the state of Ohio has acceptable stationary source annual emission statement regulations, which have been previously approved by the EPA.
**DATES:**
Comments must be received on or before April 11, 2016.

**SUPPLEMENTARY INFORMATION:**
In the Rules and Regulations section of this *Federal Register* , EPA is approving Ohio's SIP revision submittal 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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* .
