ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2013-0501; FRL 9902- 27-Region 5]

Approval and Promulgation of Air 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). The submission amends the Illinois 
Administrative Code by updating the definition of ``Volatile organic 
material (VOM) or Volatile organic compound (VOC)'' to add trans-
1,3,3,3-tetra-flouropropene (HFO-1234ze) to the list of compounds 
excluded from the definition of VOM or VOC. This revision is based on 
EPA's 2012 rulemaking which added HFO-1234ze to the list of chemical 
compounds that are excluded from the Federal definition of VOC because 
of their negligible contribution to the formation of tropospheric 
ozone.

DATES: Comments must be received on or before December 26, 2013.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this issue of 
the 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direct final rule will be withdrawn and all public comments received 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 issue of the Federal Register.

    Dated: October 17, 2013.

Regional Administrator, Region 5.
