On December 2, 2002 the United States Environmental Protection Agency (EPA) was notified via City of Bothell personnel, of an anonymous caller reporting an intentional release of diesel-like product onto the ground at the PSCI Tank Services property line, with potential migration to wetlands and resulting discharge to the nearby Sammamish River.
The PSCI Tank Services (PSCI) facility, located at 10230 East Riverside Drive in Bothell, Washington, was operated as a residential UST removal and remedial business that, reportedly, has been inactive since March 2002, due to bankruptcy. A sister company, TerraSolve, has operated at the facility and continued unfinished remediation work from PSCI since March 2002. PSCI and TerraSolve are considered the Potentially Responsible Parties (PRP).
The EPA, START, Bothell personnel, and Washington Department of Ecology personnel conducted several site visits and reconnaissance with the PRP and found multiple tanks and drums with suspected diesel wastes and oily wastewaters. The amounts of wastes estimated to be on site were 4000 gallons of diesel and wastewater, 20 to 30 drums of tank bottom sludge and used absorbents, and 50 cubic yards of stockpiled petroleum-contaminated soil.
The PRP has hired contractors and conducted a site assessment and collected samples from the various media on site. The PRP has agreed to cease waste generation activities (i.e., UST cleaning), place tarps over open tanks and drums and stockpiled soil/debris areas, and share PRP contractor sample analytical results and a removal/remediation work plan with the EPA.
