NOTICE: PROPOSED RULES

ACTION: Approval and Promulgation of Air Quality Implementation Plans:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Approval and Promulgation of Air Quality Implementation Plans; Illinois; Revisions to Emission Reduction Market System

DATES: Comments must be received on or before February 29, 2008.

DOCUMENT SUMMARY: In 1997, Illinois adopted and submitted rules establishing a cap and trade program regulating emissions of volatile organic compounds (VOC). The program was designed to address VOC sources in the Chicago area with potential to emit at least 25 tons per year. Then, in 2004, EPA replaced the ``Severe'' classification for the Chicago ozone nonattainment area with a ``Moderate'' classification, which according to EPA guidance revised the applicable definition of major sources from 25 tons per year to 100 tons per year. Illinois adopted rule revisions, submitted to EPA on January 10, 2007, to require that sources with potential to emit at least 25 tons per year remain in the program. Illinois' rule revisions also address other ramifications of the ``reclassification.'' EPA is approving these rule revisions.

SUMMARY: Illinois; Revisions to Emission Reduction Market System,

SUPPLEMENTAL 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.
