AKA CHEMPRO OF OREGON INC

Harbor Oil is a waste oil reprocessing facility located on approximately 4.2-acres in an industrial area of northeast Portland, Oregon. A tank truck cleaning facility also previously operated on the part of the property. Wetlands located west and south of the site connect to Force Lake, where recreational fishing occurs. Major events at the site: * March 1974 - a major waste oil spill from on-site storage tanks resulted in a fish kill in Force Lake. * October 1979 - a severe fire destroyed the facility and melted/ruptured five 20,000- gallon aboveground used oil tanks, causing large volumes of used oils and smaller volumes of waste paints to flow across the site, into wetlands bordering the site and Force Lake. * 1980 - the facility was rebuilt and a new tank farm was constructed. * 2000 - Consultants for EPA conducted a Preliminary Assessment/Site Inspection at the facility. Using historical documentation, sampling, and analytical results, the assessment documented the presence of several hazardous substances on-site including volatile organic compounds, semi-volatile organic compounds, metals, pesticides, and polychlorinated biphenyls (PCBs). Waste oil storage tanks and contaminated soil were identified as two primary sources of contamination. *2007- Negotiated two Administrative Orders on Consent to investigate the site and a large holding tank. * 2008/2009 - Conducted two phases of sampling for the remedial investigation. Prepared the Draft Human Health and Draft Ecological Risk Assessments. A draft Remedial Investigation Report was submitted in April 2010 for review. * 2011/2012 - Completed final Remedial Investigation (RI) report of the site contamination and assessments of the potential risks to people and the environment. * Mid 2012 - EPA expects to issue a Proposed Plan for public review and comment, which will describe how we plan to address the site. Present day site operations: Used oil recovery and recycling and biofuels production. Site Responsibility: This site is being addressed through federal and potentially responsible parties' actions.
