EPA proposes to withdraw Clean Water Act restrictions for Pebble Mine; 90-day public comment period begins

(July 11, 2017) - The EPA is proposing to withdraw its July 2014 Clean Water Act Proposed Determination that would, if finalized, have imposed restrictions on the discharge of dredged or fill material associated with the potential "Pebble Mine" in Alaska’s Bristol Bay watershed. EPA is seeking public comment by October 17, 2017, on whether to withdraw the Proposed Determination. EPA is consulting on the proposed withdrawal with federally-recognized tribal governments of the Bristol Bay region and with Alaska Native Claims Settlement Act Regional and Village Corporations with lands in the Bristol Bay watershed.
