Mr. Sandy Sears, with BP Exploration Alaska (BPXA) Inc., states that the project purpose is to re-contour the bottom of the river bed to a 4’ elevation. Work being proposed includes the dredging of up to 45,000 cubic yards (CY) of accumulated silt and gravel material from the west side of the river and the placement of the same fill material into scour depressions on the east side of the river all below the Mean High Water Mark from bank to bank within 15 acres of Riverine waters of the U.S., in the Sagavanirktok River to contour and construct a 4’ above sea level elevation on the riverbed. A temporary access ramp would be created within this area and would be 100’ long by 50’ wide, after work has been completed the area would be returned to its original contours. A portion of the work for the ramp would be located in uplands which would not be under the Corps jurisdiction. If there is any excess material it would be placed as sacrificial fill along the river embankment and bridge abutments. This scope of work is planned for 45 days. The schedule is expected to be highly variable based upon flow. The project will occur when the river is at its lowest flow volume, September 1 – October 31, 2020. All work would be performed in accordance with the enclosed plan (sheets 1-4), dated March 31, 2020. The project site is located within Section 3, T. 10 N., R. 15 E., Umiat Meridian; USGS Quad Map Beechey Point A-3 and B-3; Latitude 70.2498º N., Longitude 148.3049º W.; in Prudhoe Bay, Alaska.
