Cause detail: AT APPROXIMATELY 08:00 ON 11/18/2015, A COMPANY EMPLOYEE DISCOVERED AN APPROXIMATE 2 BBL RELEASE OF CRUDE OIL INSIDE ALVORD PUMP STATION. THE PUMP STATION WAS DOWN AND ISOLATED FROM THE MAINLINE PRIOR TO THE DISCOVERY OF THE RELEASE. THE EMPLOYEE THAT DISCOVERED THE RELEASE WAS ONSITE TO PERFORM A STATION REVIEW AND ASSESSMENT AND DID NOT HAVE RESPONSE MATERIALS AND EQUIPMENT AVAILABLE. THE AREA MANAGER WAS IMMEDIATELY ALERTED AND ADDITIONAL PERSONNEL AND RESOURCES WERE DISPATCHED TO THE SITE ARRIVING AT APPROXIMATELY 09:15 AS CLEANUP EFFORTS PROGRESSED IT WAS DISCOVERED THAT APROXIMATELY 10 GALLONS OF CRUDE OIL HAD MIGRATED TO A SMALL POND ADJACENT TO THE FACILITY DUE TO HEAVY RAIN THE NIGHT BEFORE. AT THIS TIME ADDITIONAL INTERNAL NOTIFICATIONS WERE MADE AND THE RELEASE WAS REPORTED TO THE NRC. THE OIL/WATER MIX WAS IMMEDIATELY REMOVED FROM THE POND VIA VACUUM TRUCK.

THIS PUMP STATION IS NO LONGER UTILIZED FOR NORMAL OPERATION OF THE PIPELINE AND AS SUCH THE AFFECTED PIPE AND OTHER STATION PIPING WILL REMAIN ISOLATED AND BYPASSED FROM THE MAINLINE.
