Approval and Promulgation of Implementation Plans; Illinois

On November 28, 1994, the State of Illinois submitted a State Implementation Plan (SIP) revision request to the United States Environmental Protection Agency (USEPA) for Marine Vessel Loading as part of the State's 15 percent (%) Rate of Progress (ROP) Plan control measures for Volatile Organic Matter (VOM) emissions. A final approval action is being taken because the submittal meets all pertinent Federal requirements. The control measures require marine terminals, from May 1 through September 15, to operate a vapor collection and control system which achieves a 95% control efficiency. This type of control is not required as Reasonably Available Control Technology (RACT) under the Clean Air Act, and is therefore not subject to the same RACT stringency. In the proposed rules section of this Federal Register, USEPA is proposing approval of and soliciting public comment on this requested SIP revision. If adverse comments are received on this action, USEPA will withdraw this final rule and address the comments received in response to this action in a final rule on the related proposed rule which is being published in the proposed rules section of this Federal Register. A second public comment period will not be held. Parties interested in commenting on this action should do so at this time.
