Quality Implementation Plans; Illinois 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to approve 

a revision to the Illinois State 

Implementation Plan (SIP) for ozone. 

The state is incorporating revisions EPA 

made to its definition of volatile organic 

compound (VOC). This SIP revision 

adds one compound to the list of 

compounds that are exempt from being 

considered a VOC. This is because it 

was determined that the listed 

compound does not contribute to ozone 

formation.

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final rule will be withdrawn and all 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.

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 May 22, 2008, 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 Code of Federal 

Regulations,’’ to refer to the 2007 

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.
