The Elliot Bay is used for a variety of recreational purposes, including fishing, canoeing and kayaking. The Muckleshoot and Suquamish Native American Tribes use the area for commercial and subsistence fishing. The area also provides habitat critical to Chinook salmon, which the federal government has listed as a threatened species.
Lockheed Shipbuilding and other maritime companies operated the former shipyard for approximately 45 years. Lockheed Martin Corporation discontinued its operations at the Lockheed Shipyard No. 2 in 1987.
It is believed that historical uses of the facility — shipbuilding, repair and maintenance activities — have resulted in contaminated sediments.
The sediments are habitat to numerous fish and other aquatic species, and are within a migratory corridor for endangered, threatened and other anadromous fish, which are fish that move from salt to fresh water to lay their eggs.
Historical shipyard contaminants of potential concern include
- polychlorinated biphenyls (PCBs)
- polycyclic aromatic hydrocarbons (PAHs)
- organic compounds, mercury and other metals.
- Other contaminants not directly associated with shipyard activities also may be present at the site.
The Port of Seattle
The Port of Seattle (The Port) purchased the property in 1992.
- The Port cleaned up the land area of the old shipyard under Washington State Department of Ecology oversight.
- The property is currently part of The Port’s Terminal 5, which is a container shipping facility.
- Lockheed Martin is responsible for cleanup of the aquatic sediments portion of the property, and the U.S. Environmental Protection Agency (EPA) is overseeing this activity.
Lockheed Martin has prepared a Remedial Investigation/Feasibility Study (RI/FS) to better understand the contamination and to develop a cleanup plan.
- The EPA approved the work plan in June 2008. To date, Lockheed Martin has conducted three RI field investigations at the site to provide data for the risk assessments and the RI/FS.
- Lockheed Martin conducted an analysis of data collected during the field investigations to complete the Human Health and Ecological Risk Assessments.
- Activities in 2009 and 2010 included the completion of the RI/FS; the EPA determination of the proposed plan; and Record of Decision.
