Stage of Clean-up: Remedial Assessment Not Begun
Conditions at Proposal (September 5, 2002): Harbor Oil is a waste oil reprocessing facility located on approximately 4.2 acres in an industrial area of Portland, Oregon. Site operations began in 1961. The site formerly also operated as a tank truck cleaning facility. In March 1974, there was a major spill or release of waste oil from on site storage tanks, which resulted in a fish kill in Force Lake. Following the spill, the work area at the Harbor Oil site was described by Oregon Department of Environmental Quality (ODEQ) staff as a mass of oil-soaked mud. ODEQ staff found Force Lake to be covered by a thin film of oil, and a thicker accumulation of oil, both fresh and decomposed, which had accumulated along the shorelines. In addition, in October 1979, a severe fire destroyed the facility and melted/ruptured five 20,000-gallon aboveground used oil tanks. The incident caused large volumes of used oils and smaller volumes of waste paints to flow west and south across the site, into the wetlands that border the site and Force Lake.
In 1980, following the fire, the facility was rebuilt and a new tank farm was constructed. Currently, the petroleum recovery process tanks consist of a 4,000-gallon diesel fuel storage tank; six 20,000-gallon heated storage tanks: six 20,000-gallon cold storage tanks; and 205,000-gallon and 320,000-gallon cold storage tanks. These tanks hold used petroleum products in varying stages of recovery. More...
