The Environmental Protection Agency (EPA) Region 7 announces the deletion of the Callahan property, Operable Unit 3(OU3) (Parcel ID 22U220242) of the Ellisville Superfund Site (Site) located in Wildwood, Missouri (E\1/2\, NW\1/4\, SE\1/4\, S31, T45N, R04E), 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 partial deletion pertains to all media (soil and groundwater) of the Callahan property, (OU3) Subsite. The Bliss (OU2) and Rosalie (OU1) operable units will remain on the NPL and are not being considered for deletion as part of this action. The EPA and the State of Missouri, through the Missouri Department of Natural Resources, have determined that all appropriate response actions under CERCLA, have been completed. However, the deletion of this parcel does not preclude future actions under Superfund.
