ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2008-0684; FRL-9215-3]


Approval and Promulgation of Air Quality Implementation Plans; 
Ohio; Particulate Matter Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a request submitted by the Ohio 
Environmental Protection Agency on August 22, 2008, to revise the Ohio 
State Implementation Plan under the Clean Air Act. The State has 
submitted revisions to twelve rules and rescinded one rule in Ohio 
Administrative Code (OAC) Chapter 3745-17, ``Particulate Matter 
Standards.'' The revisions were submitted by Ohio EPA to satisfy the 
State's 5-year review requirements. The particulate matter (PM) 
standards contain the particulate emission control requirements that 
have been necessary to attain and maintain the 2006 National Ambient 
Air Quality Standards for PM in the State.
    EPA is proposing to approve the revisions to nine of the OAC 3745-
17 rules. EPA proposes approving only a portion of Rule 7, while not 
acting on the portion providing a partial exemption from opacity limits 
for a lime kiln in Woodville, Ohio. We are proposing to conditionally 
approve Rule 11 based on a commitment by Ohio to address EPA's concerns 
with the large item size exemptions. EPA is not acting on Rule 3, 
regarding opacity measurement methods. Lastly, EPA is proposing to 
approve the rescission of Rule 5 from the Ohio SIP.

DATES: Comments must be received on or before November 26, 2010.

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direct final rule will be withdrawn and all public comments received 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: October 4, 2010.
