VANCOUVER, Oct. 27, 2016 /PRNewswire/ - Northern Dynasty Minerals Ltd. (TSX: NDM; NYSE MKT: NAK) ("Northern Dynasty" or the "Company") announces that its wholly-owned subsidiary, Alaska-based Pebble Limited Partnership ("Pebble Partnership" or "PLP") and the US Environmental Protection Agency ("EPA") have filed a joint Notice in federal court stating their intent to enter into mediation in an effort to resolve ongoing litigation under the Federal Advisory Committee Act ("FACA"). In September 2014, the Pebble Partnership initiated an action in federal district court in Alaska, alleging that EPA violated FACA by its close interactions with, and the undue influence of, Environmental Non-Government Organizations ("ENGOs") and anti-mine activists in developing the Bristol Bay Watershed Assessment, and its unprecedented, pre-emptive regulatory action under Section 404(c) of the Clean Water Act.
