Cause detail: LION OIL CALLED SUNOCO CONTROL ROOM TO INITIATE A DELIVERY TO MID-VALLEY PIPELINE AT LONGVIEW STATION. SUNOCO CONTROL CENTER ADVISED LION THAT WHEN MVPL PERSONNEL COMPLETED THE LINE UP FOR DELIVERY, SUNOCO CC WOULD ADVISE LION TO START DELIVERY. LION APPEARS TO HAVE STARTED ACTIONS FOR THE DELIVERY PRIOR TO BEING NOTIFIED BY SUNOCO CC THAT LINE UP WAS COMPLETE. THIS RESULTED IN A HIGHER THAN NORMAL LINE PRESSURE AT THE LONGVIEW STATION MANIFOLD YET THE PRESSURE WAS WITHIN THE DESIGN LIMITS. THIS HIGHER PRESSURE APPEARS TO HAVE CAUSED THE FAILURE AT THE POINT WHERE INTERNAL CORROSION HAD OCCURRED. RE-SUBMITTED ON 3/19/2013 TO INCLUDE PART E5F PER PHMSA REQUEST.

PHMSA trend classification: significant incident, not serious.

PHMSA standardized cause: CORROSION — INTERNAL.
