Location detail: 0+00

Cause detail: INTERNAL CORROSION

Cause detail: OPERATOR WAS MAKING HIS ROUNDS WHEN HE NOTICED OIL ON THE GROUND UNDER THE SUCTION MANIFOLD TO THE BOOSTER PUMPS. THE 36" LINE FOR THE BOOSTER WAS FOUND TO HAVE A SMALL LEAK IN THE BOTTOM AND WAS ESTIMATED THROUGH CALCULATIONS TO HAVE BEGUN AROUND 12:00AM ON DECEMBER 2ND. THE LONG SEAM OF THE PIPE IS LOCATED NEAR THE 4 O'CLOCK POSITION AND THE FAILURE WAS LOCATED AROUND THE 5 O'CLOCK POSITION. COATING WAS IN GOOD CONDITION. A SUPPLEMENTAL REPORT WILL BE SUBMITTED AFTER THIRD PARTY ANALYSIS OF THE FAILED SECTION OF PIPE. SUPPLEMENTAL NARRATIVE: THE FAILED SECTION OF PIPE WAS LOCATED ABOVEGROUND, SO A NDT WAS NOT NECESSARY, NOR WAS IT USED TO IDENTIFY THE LEAK LOCATION. INTERNAL VISUAL INSPECTION IDENTIFIED THE FAILURE LOCATION AS THE ONLY SPOT WHERE ANY ANOMALY WAS FOUND. LOW FLOW CONDITIONS PRIOR TO THE STARTUP OF ADDITIONAL TANKS FLOWING THROUGH THE MANIFOLD CREATED UNDER DEPOSIT INTERNAL CORROSION. TO PREVENT FUTURE RELEASES, PLAINS IS CONTINUALLY CONDUCTING ULTRASONIC TESTING (UT) INSPECTIONS AT THE MANIFOLD.

PHMSA trend classification: not significant, not serious.

PHMSA standardized cause: CORROSION — INTERNAL.
