Northern Dynasty Minerals (TSX:NDM,NYSEAMERICAN:NAK) shares plunged on Wednesday (February 18) after the US Department of Justice (DOJ) filed a court brief backing the Environmental Protection Agency’s (EPA) January 2023 veto of the company’s long-contested Pebble project in Alaska.

The brief supports the EPA’s prior determination to restrict development of the proposed copper, gold and molybdenum project in the Bristol Bay watershed. Northern Dynasty and its wholly owned US subsidiary, Pebble Limited Partnership, are seeking summary judgment in their legal challenge to overturn the EPA’s veto.

The veto, issued under Section 404(c) of the Clean Water Act, blocks the disposal of mine waste in certain waters within the Bristol Bay area, effectively preventing the project from advancing through the federal permitting process.
