The SSC was notified by the USCG Sector LIS at 0820 of a #2 oil release into the Connecticut River near Portland, CT at the Tr-Ramp facility. The release came from a storage tank that had a faulty check valve on a pump. Approximately 6,000 gallons of oil leaked into the secondary containment. Of that, an estimated half made its way into the CT River through a storm drain. The release may have started over a week ago and was not noticed until today. The operator noticed that they went through about a months worth of oil in 10 days. That's when they went to inspect the tank and discovered the oil pool. There is snow covering the ground and the river is frozen solid. The USCG requested trajectory information and recommendations on oil under ice response actions.
