National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of OU2 of the Libby Asbestos Superfund Site

The Environmental Protection Agency (EPA) Region 8 announces the deletion of the Operable Unit 2 (OU2), Former Screening Plant, of the Libby Asbestos Superfund Site (Site) located in Libby, Montana 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 of OU2. Operable Unit 1 (OU1), Former Export Plant; Operable Unit 3 (OU3), Former Vermiculite Mine; Operable Unit 4 and Operable Unit 7 (OU4/OU7), Residential/Commercial Properties of Libby and Troy; Operable Unit 5 (OU5), Former Stimson Lumber Mill; Operable Unit 6 (OU6), BNSF Rail Corridor; and Operable Unit 8 (OU8), Highways and Roadways, are not being considered for deletion as part of this action and will remain on the NPL. The EPA and the State of Montana, through the Department of Environmental Quality (DEQ), have determined that all appropriate response actions under CERCLA, other than operation and maintenance, and five-year reviews, have been completed. However, the deletion of these parcels does not preclude future actions under Superfund.
