ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2006-0539, EPA-R05-OAR-2006-0610; FRL-8224-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve requests submitted by the Indiana 
Department of Environmental Management on December 21, 2005 and June 
27, 2006 to revise the Indiana State Implementation Plan (SIP) in two 
areas: (1) To amend 326 IAC 1-3-4, ambient air quality standards, to 
provide consistency between state and federal reference conditions for 
measurements of particulate matter air quality; and (2) to update the 
references to the Code of Federal Regulations (CFR) from the 2002 
edition to the 2004 edition.
    In the final rules section of this Federal Register, EPA is 
approving the SIP revision as a direct final rule without prior 
proposal, because EPA views this as a noncontroversial revision and 
anticipates no adverse comments. A detailed rationale for the approval 
is set forth in the direct final rule. If we do not receive any adverse 
comments in response to these direct final and proposed rules, we do 
not contemplate taking any further action in relation to this proposed 
rule. If EPA receives adverse comments, we will withdraw the direct 
final rule and will respond to all public comments in a subsequent 
final rule based on this proposed rule. EPA will not institute a second 
comment period on this action. Any parties interested in commenting on 
this action should do so at this time.

DATES: Comments must be received on or before November 30, 2006.

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direct final rule will be withdrawn and all public comments received 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