Some of the most significant oil spills in Washington State’s history happened in the Strait of Juan de Fuca and Salish Sea.
An Emergency Response Towing Vessel (ERTV) stands ready 24/7 on the northwestern Olympic Peninsula point in the Port of Neah Bay to quickly respond. However, challenging tides affect its readiness and the ability of this deep-draft vessel to navigate the channel.
That’s about to change with a U.S. Army Corps of Engineers project that began December 11 to make navigation improvements by deepening the harbor entrance channel.
A hydraulic pipeline dredge will deepen the 4,500-foot entrance channel to -21 feet from its current depth, allowing unrestricted access for ocean-going tugs, barges, and larger ships transiting Neah Bay during low tide.
USACE is expected to remove up to 30,000 cubic yards of never-before-dredged sediment material from the channel that’s expected to take two months to complete, pending weather conditions.
“ This project will help to ensure that the rescue tug based at Neah Bay is ready to respond to marine emergencies on Washington’s coast ,” said Rich Doenges , Southwest Region director for the Washington Department of Ecology. “ We think the channel deepening represents a necessary step to prevent impacts to our state’s sensitive coastal environment and preserve our Pacific shorelines .”
Seattle District Project Manager and biologist Juliana Houghton emphasized how the dredged material is perfect for reuse and will help fortify a nearby beach.
“ We’ll place the beneficial use dredged material in an area along the shoreline that needs rehabilitation because of a lack of naturally occurring stream sediment ,” she said. “ The goal is to restore intertidal habitat by depositing the dredged material as beach nourishment .”
Deepening the Neah Bay entrance channel will reduce the emergency response tugs operating costs by minimizing the need for vessels to remain outside the bay in deeper waters during low tide.
