          - 40 CFR Part 52
          - [EPA-R05-OAR-2014-0504; FRL-9921-43-Region 5]

# AGENCY:

Environmental Protection Agency.

# ACTION:

Proposed rule.

# SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Illinois State Implementation Plan. The revision amends the Illinois Administrative Code by updating the definition of volatile organic material or volatile organic compound to exclude additional compounds. This revision is in response to EPA rulemakings in 2013 which exempted these chemical compounds from the Federal definition of volatile organic compounds because, in their intended uses, the compounds have a negligible contribution to tropospheric 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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                           ( print page 9259)                        in the Rules section of this                     **Federal Register**                    .
