The U.S. Navy is proposing to remove the open-pile wharfs at Berths 40 and 41, located at Norfolk Naval Shipyard, Portsmouth, VA, and reconstruct these facilities as enclosed wharf systems in the same location. Due to the presence of elevated concentrations of Total Petroleum Hydrocarbons (TPH), oil and grease, and other anthropogenic chemical constituents (metals and PCBs), construction will include a variety of measures to (a) control resuspension of contaminated sediments during construction to prevent redeposition within the waterway, (b) remove contaminated sediments by dredging where operationally feasible and (c) isolate contaminated sediments from the aquatic environment with structural means where removal is not feasible. Public comments should be received by the close of business on October 13, 2023.
