Polychlorinated Biphenyls; Coastal Ohio

Coastal Ohio | 1986-Aug-22

Initial Notification: At approximately 2040 on August 2l1, 1986, during an electrical switching evolution at a nuclear power facility, an electrical short circuit fault caused a transformer to leak approximately 90 gallons of polychlorinated biphenyls (PCBs) containing transformer oil onto the floor of the water treatment building. Most of the oil was contained on the floor in the vicinity of the transformer, although some leaked through floor penetrations into the basement, with a small amount accumulating in the floor drainage system.
