National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the Naval Industrial Reserve Ordnance Plant (NIROP) Superfund Site

EPA Region 5 is publishing a direct final Notice of Deletion of Operable Unit 2 (OU2) of the Naval Industrial Reserve Ordnance Plant (NIROP) Superfund Site (Site), located in Fridley, Minnesota, from the National Priorities List (NPL). 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 (NCP). This direct final partial deletion is being published by EPA with the concurrence of the State of Minnesota, through the Minnesota Pollution Control Agency (MPCA), because EPA has determined that all appropriate response actions under CERCLA at the OU, identified herein, other than operation, maintenance, and five-year reviews, have been completed. However, this partial deletion does not preclude future actions under Superfund. EPA divided the NIROP Site into three portions, known as OUs, for ease of addressing its contaminant issues. This partial deletion pertains to OU2, which includes all the unsaturated soils within the legal boundaries of the NIROP Superfund Site exclusive of unsaturated soils underlying the former Plating Shop Area (see Site Map in the SEMS ID 446572 document listed in the Deletion Docket for OU2). The following areas will remain on the NPL and are not being considered for deletion as part of this action: OU1 and OU3. OU1 includes the contaminated groundwater within and originating from the NIROP Superfund Site. OU3 includes all the unsaturated soils underlying the former Plating Shop Area.
