(Seattle, Wash. – March 7, 2007) EPA has added the Lockheed West Seattle site to the Superfund “National Priorities List” (NPL). The Lockheed site, located at 3443 West Marginal Way SW on Elliott Bay in Seattle, Washington, qualifies for listing because it was found to pose serious, ongoing, threats to human health and the environment. The NPL is EPA's list of the most serious uncontrolled or abandoned hazardous waste sites identified for possible long-term clean up action under Superfund.

Historic industrial practices at this former shipyard released contaminants into the bay, including metals, polychlorinated biphenyls (PCBs), and petroleum products. An NPL listing notifies the public that EPA believes a site requires further study and possible cleanup under EPA’s Superfund program.

The Lockheed West Seattle site is one among several other contaminated sediment sites in the Harbor Island area that require remediation. Successful cleanups have already been completed at the Todd Shipyard facility and another Lockheed shipyard. At these sites, 330,000 cubic yards of contaminated sediments were dredged and removed from the sites, 7800 pilings were removed, and over 5 acres of fish-friendly inter-tidal habitat were created. Sediment cleanup projects like these are a significant part of the EPA's continuing efforts to the remove toxins from Puget Sound.
