At 0530 on 22-July a tanker truck carrying 4,500 gallons of 50% hydrogen peroxide solution overturned traveling on Highway 42 in Bedford, KY. An NRC report was made at 1100 stating 50 gallons of material was released to a drainage ditch. OSC Art Smith was dispatched to the scene and met with Kentucky Department of Environmental Protection SOSC to oversee the transfer operations and clean-up activities. Approximately 3,500 gallons of material was released from the tanker, a portion of which traveled via a drainage ditch into the Little Kentucky River. No environmental impacts were observed in the River. The RP utilized a response contractor from the manufacturer of the product, Arkema. The crew successfully transferred the remaining 1,000 gallons from the tanker. All personnel left the site at approximately 0100 on 23-July. Crews will resume work today with soil excavation under KDEP oversight.
