The Terminal 117 Early Action Area is on the west side of the Lower Duwamish Waterway, about 3.5 miles from the southern tip of Harbor Island, near downtown Seattle. The upland part of the site includes the former Malarkey Asphalt Company location and other property owned by the Port of Seattle.
In 2000, EPA oversaw the Port’s removal of some soil contaminated with polychlorinated biphenyls (PCBs) from the property, including some areas formerly owned by Malarkey Asphalt.
In 2003, EPA named Terminal 117 as an "early action area" within the Lower Duwamish Waterway Superfund site. Early actions are being done in highly contaminated areas of the waterway, to reduce the health risks to people and the environment. The Port, under an EPA order, continues to investigate the contamination and cleanup options for the uplands, shoreline, and sediments.

In 2004, the city of Seattle found PCBs in street dust and dirt in the neighborhood near Terminal 117. The City did an interim cleanup of the PCBs by removing contaminated dirt and covering up other areas so that people would not come into contact with the chemicals.
In 2008, the City did more testing and found PCBs and dioxin in some streets and yards in the neighborhood. The EPA, City and Port are testing the neighborhood streets and yards to figure out where and how much PCB and dioxin contamination is in the neighborhood, and which areas may need to be cleaned up.
