TACOMA — The U.S. Navy on Wednesday agreed to a 10-year moratorium on scraping the hulls of decommissioned vessels in Puget Sound.
The deal, filed in U.S. District Court in Tacoma, settles a lawsuit filed by the Suquamish Tribe and two environmental groups, Washington Environmental Council and Puget Soundkeeper Alliance. Washington Attorney General Bob Ferguson joined the lawsuit.
The lawsuit alleged that when the Navy cleaned the hull of the decommissioned aircraft carrier Independence at the Puget Sound Naval Shipyard in 2017, they used abrasive scrubbers and blasted the hull with powerful jets of water. That sent bits of paint, the metals zinc and copper, and other contaminants into Sinclair Inlet.
The Navy disputed that it caused pollution and said it was cleaning the hull so that as the aircraft carrier was towed to Texas for dismantling, it wouldn’t bring any invasive species with it.
