[EPA-R05-OAR-2014-0385; FRL-9917-91-Region 5]


Approval and Promulgation of Air Quality Implementation Plans; 
Ohio; Ohio PM<INF>2.5</INF> NSR

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve, under the Clean Air Act (CAA), revisions to Ohio's state 
implementation plan (SIP) as requested by the Ohio Environmental 
Protection Agency (OEPA) to EPA on June 19, 2014. The revisions to 
Ohio's SIP implement certain EPA regulations for particulate matter 
smaller than 2.5 micrometers (PM<INF>2.5</INF>) by establishing 
definitions related to PM<INF>2.5</INF>, defining PM<INF>2.5</INF> 
increment levels, and setting PM<INF>2.5</INF> class 1 variances. The 
revisions also incorporate changes made to definitions and regulations 
that recognize nitrogen oxides (NO<INF>X</INF>) as an ozone precursor, 
revising and adding definitions, adding Federal land manager 
notification requirements, and incorporating minor organizational or 
typographical changes.

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direct final rule will be withdrawn and all public comments received 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 6, 2014.

Regional Administrator, Region 5.
