Accident Classified As: No Information Given
An operator making a normal round at the Cooling Water Platform noticed oily water sump, D8410, overflowing to the river bature. It was later determined that the check valve on the discharge of the pump had failed in the open position, allowing untreated wastewater to backflow in to the sump. Less than one gallon of oil was released.
Not preventable. The mechanical failure of the check valve was most likely a manufacturer defect, as this valve was in service for approximately on month.
Upon discovery, the operator secured the valve and started the pump to evacuate the sump. United States Environmental Services (USES) was dispatched to deploy containment boom around the immediate area and use absorbent boom to recover any potential hydrocarbon present. The clean up was completed on Monday, May 2, 2011. CRLLC replaced the sump check valve on May 4, 2011. Additionally, in an effort to minimize the likelihood of a reoccurence, CRLLC installed an independent high level alarm system on the sump.
