The Dominion, a 128-foot wooden U.S. Army tugboat, sank at the Bremerton Marina Sept. 17, resulting in large quantities of diesel and motor oil being spilled into Sinclair Inlet, per the state Department of Ecology.

The Port of Bremerton, the U.S Coast Guard and Ecology were working together to contain the spill, per an Ecology statement. Marina staff set booms and buoys around the vessel to contain as much debris as possible.

As of Sept. 19, Ecology hasn’t received reports of oiled wildlife and an investigation into the cause of the sinking is still underway. The Port of Bremerton also closed the marina to public fishing, per an Ecology statement.

On Sept. 20, Ecology reported the Dominion had an additional release of product and additional response teams were activated. “Responders estimate that approximately 5,000 gallons of oil-water mixture has been recovered, with 2,500 gallons estimated to be oil,” an Ecology statement says. “We ask that people please stay out of the immediate vicinity of the tug sinking as our responders work to clean up this spill.”

Ecology said in order to prevent oil and diesel from being spread throughout Puget Sound, boaters were initially encouraged to stop operations at the Bremerton Marina, as vessels would need to undergo decontamination efforts. Any type of propulsion can spread oil, diesel and cause harm to aquatic and marine mammal life.

No Washington State Ferries or Kitsap Transit Bremerton fast ferry operations were impacted as of Sept. 18, WSF and KT both confirmed.

This incident follows the sinking of the derelict vessel Cairdeas Sept. 7 in Sinclair Inlet, per the National Oceanic and Atmospheric Administration.

An Ecology spokesperson confirmed the two incidents aren’t connected and large spills aren’t common statewide or in Kitsap County. In the event of a spill, people and businesses are required to report it regardless of the size.
