ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2009-0807; FRL-9209-2]


Approval and Promulgation of Air Quality Implementation Plans; 
Ohio; Ohio Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve amendments to the Ohio 
Administrative Code (OAC) relating to the consolidation of Ohio's 
Ambient Air Quality Standards (AAQS) into Ohio's State Implementation 
Plan (SIP) under the Clean Air Act. On April 8, 2009, and August 11, 
2009, Ohio EPA adopted amendments to various rules in the

[[Page 65595]]

OAC to consolidate the state's AAQS. On September 10, 2009, Ohio EPA 
requested from EPA approval of amendments to OAC with the intent to 
consolidate Ohio's AAQS into a single rule to provide greater 
accessibility for the regulated community and to the citizens of Ohio. 
EPA is proposing to approve the request because the revisions clarify 
the state's rules and thus better serve the purpose of providing for 
meeting these standards.

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direct final rule will be withdrawn and all public comments received 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

    Dated: September 17, 2010.
