Superfund record of decision amendment (EPA region 10): Harbor Island (lead), Seattle, King County, WA, January 25, 1996

Technical Report ·
OSTI ID:464258

This decision document modifies the remedial action for treating petroleum contaminated soil at the Soil and Groundwater Operable Unit of the Harbor Island Site (Site) in Seattle, Washington. The ROD for this operable unit, signed on September 30, 1993, required thermal desorption treatment for hot-spot soil with total petroleum hydrocarbon (TPH) concentrations exceeding 10,000 mg/kg. The purpose of this Record of Decision amendment is to allow TPH hot-spot soil, which can be classified as non-dangerous waste, to be disposed at the Roosevelt Regional Landfill in Klickitat County, Washington, or an equivalent landfill. After excavation, soil will be analyzed to determine if it is non-dangerous or dangerous waste. Soil which is determined to be non-dangerous according to these analyses will be disposed at an offsite landfill. Soil which is dangerous waste will be treated by thermal desorption as specified in the original remedy.
