Incident Narrative

AT 0610 ON 5/6/13 EXXON OPERATOR DISCOVERED PRODUCT LEAKING FROM COLONIAL'S LINE 19 SOLATRON PUMP. THE OPERATOR IMMEDIATELY CALLED COLONIAL'S CONTROL CENTER. LINE 19 WAS SHUTDOWN @ 0610 AND LOCAL COLONIAL PERSONNEL WERE NOTIFIED. COLONIAL TECHNICIANS ARRIVED ONSITE AT 0630 AND ISOLATED THE PUMP. COLONIAL'S OPERATIONS MANAGER (OM) WAS NOTIFIED AT 0630, DISTRICT ENVIRONMENTAL MANAGER (DEM) WAS NOTIFIED AT 0640 AND DISTRICT DIRECTOR OF OPERATIONS (DDO) WAS NOTIFIED AT 0652. TECHNICIANS DETERMINED THAT A FAILED PUMP SEAL WAS THE SOURCE OF THE LEAK AND REPLACED THE PUMP AS A PERMANENT REPAIR. IT IS ESTIMATED THAT 190 GALLONS OF PRODUCT WAS RELEASED, THE MAJORITY OF WHICH WAS CONTAINED IN 6' BY 8' BY 4' DEEP EXCAVATION ASSOCIATED WITH UNRELATED WORK AT THE STATION. THE EXCAVATION CONTAINED RAINWATER WHICH APPEARS TO HAVE PREVENTED DOWNWARD MIGRATION OF THE PRODUCT. APPROXIMATELY 20 YARDS OF SOIL WERE IMPACTED AROUND THE PERIMETER OF THE EXCAVATION AND IN THE VICINITY OF THE PUMP. THE MAJORITY OF THE RELEASE WAS CONTAINED WITHIN THE CURBED AREA OF THE STATION WITH A SMALL AMOUNT IMPACTING A 8' BY 3' AREA OUTSIDE OF THE EASTERN CURB. AT THIS TIME GROUNDWATER DOES NOT APPEAR TO HAVE BEEN IMPACTED BY THE RELEASE. AN ESTIMATED 150 GALLONS WAS RECOVERED FROM THE EXCAVATION BY VACUUM TRUCK, APPROXIMATELY 20 GALLONS WERE CONTAINED WITHIN IMPACTED SOILS, AND 20 GALLONS WERE LOST TO EVAPORATION. DURING THE WEEK OF MAY 6TH, THE MAJORITY OF SOILS IMPACTED BY THE RELEASE WERE EXCAVATED AND TEMPORARILY STORED ONSITE AWAITING DISPOSAL. WORK CONTINUES AT THE SITE TO FULLY INVESTIGATE AND CONFIRM EXTENT OF IMPACTS FROM THE RELEASE AND TO ADDRESS PRE-EXISTING SOIL CONTAMINATION ISSUES FOUND DURING THE RESPONSE.
