What is an Early Action?
Early Action cleanup areas are parts of a Superfund site that EPA has determined may become a threat to people or the environment before the long-term cleanup for the site is completed.

Early Action Cleanup Areas
Site Summary
Boeing Plant 2 is located on the east bank of the Duwamish Waterway at 7755 East Marginal Way South in Seattle and Tukwila, Washington. Plant 2 was built in the late 1930s and was a major aircraft manufacturing facility during World War II. PCBs from large electricity generators and transformers were released at Plant 2 and into the LDW. A wide range of other hazardous chemicals are found in the soil, groundwater, and sediment, including metals (chromium, copper, cadmium), cyanide, petroleum products, and chlorinated solvents, such as trichloroethylene. Plant 2 is a Resource Conservation and Recovery Act (RCRA) permitted hazardous waste facility. Boeing is under an EPA RCRA Order to investigate and study cleanup options for Plant 2. Boeing has already completed several interim measures to clean up or control high risk areas before the final cleanup, including: removed nearly a mile of PCB-contaminated joint caulk; cleaned up storm drains to reduce metals and PCBs; and treated contaminated groundwater.
When the Lower Duwamish Waterway became a Superfund site, several “hot spot” areas of sediment contamination were targeted for cleanup before the larger Superfund cleanup. Boeing Plant 2 is one of these hot spot cleanups. Three other hot spot cleanups are nearby: Slip 4 to the north, Jorgensen Forge to the south and Terminal 117 across the waterway.
On March 29, 2011, EPA released a Statement of Basis that describes the cleanup options for the sediments and shoreline at Boeing Plant 2. The Statement of Basis is available for public review and comment on this website, at the South Park Library and at EPA’s Region 10 Library. The cleanup options would dredge (excavate) the sediments and then backfill with clean material or place a thick cap to isolate the contamination. EPA will respond to public comments and decide on the cleanup plan in a Final Decision and Response to Comments. Cleanup options for the Plant 2 uplands areas (the rest of the Plant 2 site) will be issued in a second Statement of Basis in 2012.
