Our team completed seven different evaluations to characterize the potential toxicity of sediment and elutriate created during dredging, as well as characterize the potential bioaccumulation of contaminants from the sediment if disposed of in approved open-ocean disposal areas. Environmental Protection Agency protocols to determine suitability of the sediment for open water ocean disposal. Tetra Tech conducted sediment toxicity and bioaccumulation testing following USACE and U.S. Army Corps of Engineers (USACE) by conducting sediment testing for the characterization of sediment to be removed during routine maintenance dredging for five commercial harbors in Hawaii, including Honolulu, Kalaeloa (Barber’s Point), Nawiliwili, Kahului, and Hilo. The command expects work to occur in Hawaii through September 2027 and is obligating $463 million in fiscal 2023 military construction funds.Īccording to DOD, the task order contains three options that could bring the award’s total value to $3.4 billion if exercised.Nereis virens is used to determine the potential bioaccumulation of contaminants from sediments to be dredged prior to open ocean disposal Previous Next Pacific Fleet’s nuclear-powered submarines. The Navy said the planned project will replace Dry Dock 3 with a new graving dock, dubbed Dry Dock 5, meant to help the Pearl Harbor Naval Shipyard improve its capability to maintain and modernize the U.S.
In 2021, NAVFAC Pacific awarded five companies spots on the potential $8 billion multiple-award, indefinite-delivery/indefinite-quantity contract in support of the Shipyard Infrastructure Optimization Program, which seeks to integrate industrial plant equipment and other infrastructure investments at the service branch’s four public shipyards to meet requirements for nuclear fleet maintenance. The Naval Facilities Engineering Systems Command Pacific is the contracting activity and received four proposals for project, as part of a contract awarded in November 2021, the Department of Defense said Friday.
