On July 2, 2026, the United States Department of Justice lodged a proposed Consent Decree with the United States District Court for the District of Montana entitled United States and State of Montana v. Columbia Falls Aluminum Company, LLC, Civil Action No. 9:26-cv-00099-KLD.

 

The Consent Decree resolves State of Montana’s claims against the Columbia Falls Aluminum Company, LLC (CFAC) under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. § 9607(a), and the Montana Comprehensive Environmental Cleanup and Responsibility Act, §§ 75-10-701, et seq., for the recovery of costs and performance of work related to the release of hazardous substances at the Anaconda Aluminum Company Columbia Falls Reduction Plant National Priorities List Site (also known as the Columbia Falls Aluminum Company, or CFAC) (the “Site”) in Flathead County, Montana. 

 

Montana put the Consent Decree out for public comment for 30 days as described in the Response to Comments.

 

Through consideration of the public comments and responding to them, Montana has determined that the public comments do not disclose facts or considerations that indicate that the Settlement Agreement is not in the public interest; Montana therefore is not seeking to withdraw or withhold its consent and supports prompt entry of an order by the Court approving the Settlement Agreement. Montana also has determined that the settlement is fair, adequate, reasonable, and consistent with the goals of the Comprehensive Environmental Response, Compensation and Liability Act, as amended, 42 U.S.C. § 9601 et seq. (CERCLA) and CECRA, § 75-10-701 et seq.
