Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a state submission as a revision to the Illinois state implementation plan (SIP) for ozone. The revision, submitted on May 30, 2017, incorporates changes to the Illinois Administrative Code definition of volatile organic material, otherwise known as volatile organic compounds (VOC). The revision removes recordkeeping and reporting requirements related to the use of t-butyl acetate (also known as tertiary butyl acetate) as a VOC, and is in response to an EPA rulemaking that occurred in 2016. Illinois also added information to provide clarity to the list of compounds excluded from the definition of VOC.

DATES:

Comments must be received on or before December 4, 2017.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this issue of the Federal Register, EPA is approving the Illinois’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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
