EPA is proposing to delete a portion of Libby, Montana Superfund site from National Priorities List

Public comments are being accepted on this proposed deletion through May 2.

March 22, 2022

Libby, Mont. – EPA and the Montana Department of Environmental Quality (DEQ) invite the public to comment on the proposal to delete Operable Unit 6 (OU6) of the Libby Asbestos Superfund site from the National Priorities List (NPL). Comments will be accepted from March 21 through May 2 (extended).

Operable Unit 6 includes BNSF-owned and operated railyards in the towns of Libby and Troy, MT and approximately 42 miles of railroad right-of-way. OU6 has been cleaned through previous remedial actions between 2004 and 2018.

OU6 does not require any additional remedial action to protect human health and the environment and is therefore eligible to be partially deleted from the site. A partial deletion is part of the superfund process which can remove a section, or operable unit, of the site from the NPL because no additional remediation is expected. The area will continue to be subject to operation and maintenance activities, including regular reviews for protectiveness. EPA, in consultation with DEQ, will continue to address contamination concerns at remaining Operable Units of the Libby Asbestos site, which includes the former mine site. The proposal to delete OU6 is available at: http://www.regulations.gov under docket number: EPA-HQ-OLEM-2021-0922-0001

You may comment on the proposed partial deletion of OU6 using the following methods.
