Abstract:

The ex-INDEPENDENCE CV 62, which had been moored at Mooring G at Naval Base Kitsap in Bremerton, WA NBK-BREM since decommissioning in September 1998 was towed on March 11, 2017 to Brownsville, TX, where the ship arrived on June 1, 2017 for dismantling. Based on a consultation with National Oceanic and Atmospheric Administration NOAA National Marine Fisheries Service NMFS, the Navy was required to clean the ships hull prior to towing in order to mitigate the possibility of transferring invasive species to other regions and thereby harm endangered species and habitats. This report presents the sediment sampling and analysis results to assess potential impacts to sediment quality from biofouling removal from CV 62 while it was moored at NBK-BREM and the Puget Sound Naval Shipyard and Intermediate Maintenance Facility PSNS and IMF in Sinclair Inlet, Puget Sound, WA. The data developed for this study provided a basis for1- determining whether biofouling removal from CV 62 impacted sediment quality at Mooring G and 2- assessing the nature and extent of any impact. The findings from this study showed that the potential impact of biofouling removal to the benthic community from the release of copper and zinc was low and that the benthic community in the area of the vessel was not adversely degraded.
