Case Summary: Cleanup Order for Lockheed West Seattle/Shipyard 2 will help Puget Sound

On April 28, 2015, the U.S. Environmental Protection Agency (EPA) issued a unilateral administrative order (UAO) for remedial design/remedial action (RD/RA) to Lockheed Martin Corporation for the cleanup of their property on Seattle’s Elliott Bay. The Lockheed West Seattle/Shipyard 2, is the latest in a series of more than 50 federal, state, and privately-led legacy contamination cleanups around Elliott Bay and the lower Duwamish waterway.

Under the cleanup order, approximately 167,000 cubic yards of contaminated material are expected to be removed over the course of the cleanup, reducing site risks to people’s health and the environment. The multi-year cleanup is expected to begin in 2018.

Pollution released into Elliott Bay is of particular concern, since the Muckleshoot and Suquamish Tribes use the area around the site for commercial, subsistence and ceremonial fishing. The bay is used for a variety of recreational purposes, including fishing, canoeing and kayaking. The area also provides habitat critical to Chinook salmon, which the federal government has listed as a threatened species.

Information about the Lockheed West Seattle Superfund Site

The Lockheed West Seattle Superfund site encompasses 40 acres located near the confluence of the West Waterway and Elliott Bay, on the western side of the city of Seattle, Wash. Historic industrial practices (construction, dry dock ship repairs, vessel sandblasting, and painting) at this former shipyard released contaminants including metals, polychlorinated biphenyls (PCBs), and petroleum products that resulted in contamination of underlying sediments in Elliott Bay. The Lockheed Shipbuilding and Puget Sound Bridge and Dredge Company conducted shipbuilding and repairs at the site from 1946 to 1987. Operations at those companies contaminated the site and surrounding areas, which were all released directly into Elliott Bay.
