ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2010-0999; FRL-9304-9]

Approval and Promulgation of Air Quality Implementation Plans; 
Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a request submitted by the Indiana 
Department of Environmental Management on November 24, 2010 to revise 
the Indiana State Implementation Plan (SIP). The submission revises the 
Indiana Administrative Code (IAC) by amending and updating the 
definition of ``References to the Code of Federal Regulations,'' to 
refer to the 2009 edition. The submission revision also makes a minor 
revision to the definition of ``Nonphotochemically reactive 
hydrocarbons'' or ``negligibly photochemically reactive compounds'' by 
deleting an outdated Federal Register citation.

DATES: Comments must be received on or before June 13, 2011.

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direct final rule will be withdrawn and all public comments received 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: May 3, 2011.
Susan Hedman,
Regional Administrator, Region 5.
