Environmental Protection Agency December 31, 2007 – Federal Register Recent Federal Regulation Documents

EPA is proposing disapproval of a revision to the Illinois Ozone State Implementation Plan (SIP). On August 17, 2005, Illinois requested that five compounds be added to its list of compounds exempt from being considered a volatile organic compound (VOC). EPA no longer considers four of the compounds to be VOCs because the compounds were shown to be negligibly photochemically reactive. Thus, the compounds do not lead to ozone formation. For the fifth compound, t-butyl acetate, EPA determined that it is not considered a VOC for emission limits and VOC content requirements, but it is considered a VOC for recordkeeping, emission reporting, and inventory requirements. Illinois has indicated it is correcting the restrictions on t-butyl acetate. Consequently, EPA is alternatively proposing approval of the SIP revisions if t-butyl acetate is removed from the list of compounds exempt from being considered VOC or if the special requirements for t-butyl acetate are clearly indicated. Illinois must submit the supporting documentation during the comment period for this rule.

In accordance with section 122(i) of the Comprehensive Environmental Response, Compensation, and Liability Act, as amended (``CERCLA''), 42 U.S.C. 9622(i), notice is hereby given of a proposed administrative settlement which includes compromise of past response costs incurred in connection with the Mason Road Lead site in Mason Ohio with the Board of Education Mason of Mason City School District. The settlement requires Settling Party to reimburse U.S. EPA Hazardous Substance Superfund $15,917.36 for costs incurred by U.S. EPA since December 11, 2004, through the effective date of this Administrative Order on Consent to oversee the clean-up of the Mason Road Lead site. The total past costs incurred between December 11, 2004, and December 9, 2006, are $19,896.70 and are being compromised in consideration of the settling party having completed a removal action under the terms of a Unilateral Administrative Order Docket No: V-W-04-C-803 issued pursuant to CERCLA section 106(a), 42 U.S.C. 9607(a). The settlement includes a covenant not to sue the settling party pursuant to section 107(a) of CERCLA, 42 U.S.C. 9607(a). For thirty (30) days following the date of publication of this notice, the Agency will receive written comments relating to the settlement. The Agency will consider all comments received and may modify or withdraw its consent to the settlement if comments received disclose facts or considerations with indicate that the settlement is inappropriate, improper, or inadequate. The U.S. EPA's response to any comments received will be available for public inspection at the U.S. EPA Record Center, Room 714, U.S. EPA, 77 West Jackson boulevard, Chicago, Illinois.
