Mr. Jesse Peterson, with Alaska Industrial Development and Export Authority, states the project purpose is to conduct annual maintenance dredging and beach nourishment at the DeLong Mountain Transportation System Port, which services the Red Dog Mine, in western Alaska.  The proposed project, dredge up to 500,000 cubic yards (cy) of subsurface marine material for a period of 10 years (an average of 50,000 cubic yards annually) from an 8.5-acre area of located within navigable waters of the U.S.  Materials would be dredged to a depth of minus 22 feet elevation (relative to 0 feet Mean Low Lower Water) waterward of the mean high-water mark.  Discharge up to 500,000 cy (an average of 50,000 cubic yards annually) of dredged material into an adjacent 5.7 acres shallow water, intertidal disposal area below the High Tide Line (HTL).  Excavate up to 0.05 acres of beach sand between Mean High Water and the HTL, discharge beach sand into the 5.7-acre shallow water discharge area.  Dredging below waterline in the port basin has been done historically with a clam shell on the dock crane, and when required, a clam shell on a barge.  The plan is to continue with clam shell dredging.  Excavation and discharge of beach sand would occur using a dozer.  Some non-jurisdictional excavation of beach sand may take place above HTL.  Work would start annually June 1 or as soon as the port is ice free.  The dredging and discharge areas are shown on the attached plans.  All work would be performed in accordance with the enclosed plan (sheets 1-1), dated June 24, 2021.  The project site is located within Section 10, T. 25 N., R. 24 W., Kateel Meridian; Latitude 67.5766º N., Longitude 164.0600º W.; approximately 90 miles north of Kotzebue, Alaska.  Please contact Leslie Tose at (907) 753-5515, toll free from within Alaska at (800) 478-2712, by fax at (907) 753-5567, or by email at: if further information is desired concerning this notice.
