Project Overview
The Terminal 117 cleanup site (T-117), located on the west bank of the Lower Duwamish Waterway in South Park, is a joint cleanup project by the Port of Seattle and City of Seattle. This site was identified for early cleanup (before the larger river cleanup) because the upland property, river bank and sediments in the waterway have high concentrations of PCBs (polychlorinated biphenyls), dioxin/furans and other contaminants. T-117 is designated as an Early Action Area as part of the Lower Duwamish Waterway Superfund Site listed by the U.S. Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).
In fall of 2010, EPA issued the final removal Action Memorandum for the T-117 site based on the findings in the project's cleanup plan (EE/CA). The Action Memorandum outlines a plan to remove soil and river sediment to reduce PCBs to levels that will protect the river environment and reduce health risks to people. Cleanup design is underway, and cleanup work will begin in early 2013. Please stay tuned for more updates and upcoming opportunities to get involved as the design process moves along.
