The Environmental Protection Agency (EPA) Region 5 is publishing a direct final Notice of Deletion of the Research Center Property (RCP) of the Beloit Corporation Superfund Site (Site), in Rockton, Illinois from the National Priorities List (NPL). This partial deletion includes all media at the 20-acre RCP. The rest of the Site remains on the NPL and is not affected by this action. The NPL, promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan. EPA is publishing this direct final partial deletion with the concurrence of the State of Illinois because all appropriate response actions at the RCP under CERCLA have been completed, other than maintenance, monitoring and five-year reviews. However, this partial deletion does not preclude future actions under Superfund.
