Past Project: PCB Spill from Transformer Fire in Columbia Falls, Montana

A transformer fire resulted in the uncontrolled release of approximately 1,100 gallons of oil containing polychlorinated biphenyls (PCBs). The release impacted surrounding soils, gravel, and a containment system consisting of a catch basin, piping, and an oil/water separator. Olympus excavated and loaded into roll-off containers 400 tons of contaminated soil and 300 tons of contaminated gravel. The roll-off containers were prepared for shipment and the contaminated material was transported to a Toxic Substances Control Act (TSCA)-approved disposal facility. Oil within the contaminated oil/water separator was recovered and pumped into drums for proper disposal. Approximately 35,000 gallons of water from the separator was treated using granular activated carbon and the separator was hand-cleaned using a PCB solvent.
