PLAINS PIPELINE, L.P.

Incident Narrative

APPROXIMATELY 10 BBLS OF CRUDE OIL WERE RELEASED WHEN A 1/4'' STAINLESS STEEL CORROSION INHIBITOR SUPPLY LINE CONNECTION CRACKED NEAR THE INJECTION POINT ON THE PIPELINE. THIS CORROSION INHIBITOR INJECTION STATION IS IN A RURAL AREA. WINDS WERE HIGH ON THE DAY THIS OCCURRED AND AS A RESULT THIS OIL SPRAY WAS CARRIED ONTO LANDOWNER PROPERTY DAMAGING THE HOMEOWNERS TRAILER HOME AND YARD. PLAINS IS REPLACING THE TRAILER HOME AND RETURNING THE YARD AND ENVIRONMENT BACK TO ITS ORIGINAL STATE. AT THIS TIME THE THREADED CONNECTION SAMPLE HAS BEEN SENT TO THE LAB FOR ANALYSIS. A SUPPLEMENTAL REPORT WILL BE SUBMITTED TO UPDATE THE COSTS AND CAUSE OF THIS RELEASE. SUPPLEMENTAL NARRATIVE: PLAINS HAS DETERMINED THAT THE CAUSE OF THE THREADED CONNECTION FAILURE WAS FATIGUE CRACKING. THE INJECTION POINT REMAINS OUT OF SERVICE AND DISCONNECTED FROM THE PIPELINE. PART A, NUMBER 18B HAS BEEN UPDATED AND THE YEAR THE ITEM WAS INSTALLED HAS BEEN ADDED IN PART C, NUMBER 4. THE SUPPLEMENTAL REPORT IS IN REFERENCE TO THE TIMES PROVIDED. THIS RELEASE WAS REPORTED TO THE PIPELINE OPERATOR AT APPROXIMATELY 23:42, LOCAL TIME, ON 11/5/2013 (#18A). THE CONTROL CENTER IMMEDIATELY SHUT DOWN THE LINE AT 23:47 ON 11/5/2013 AS A PRECAUTION. IT TOOK THE LOCAL PIPELINE OPERATOR UNTIL 2:20, ON 11/6/2013, TO DRIVE TO THE SITE AND ISOLATE THE CHEMICAL INJECTION UNIT. THE SITE TAKES APPROXIMATELY 2.5 HOURS TO REACH BY CAR. DARKNESS OF NIGHT MADE IT DIFFICULT TO ASSESS THE DAMAGE, UNTIL THE NEXT MORNING. AT 10:27 ON 11/6/2013, THE DIVISION MANAGER ON-SITE MADE THE DETERMINATION THE COST WOULD EXCEED $50,000, WHICH TRIGGERS A NOTIFICATION TO NRC. THIS IS WHEN INFORMATION WAS GATHERED TO ENTER AN ONLINE NRC REPORT, WHICH WAS ENTERED AT 11:13, 46 MINUTES LATER. CONFIRMATION AND NRC# 1065040 WAS ISSUED AT 11:34 ON 11/6/2013. AS INSTRUCTED BY THE GENERAL INSPECTOR, WE ATTEMPTED TO UPDATE PART A, #4 TO STATE 10:27 ON 11/6/13 FOR WHEN PLAINS DETERMINED THE INCIDENT MET THE REPORTING CRITERIA, HOWEVER, THE ONLINE FORM DOES NOT ALLOW THIS. THIS TIME LISTED FOR PART A, #4, 23:42 ON 11/5/2013, IS WHEN THE POTENTIAL RELEASE WAS REPORT TO THE PIPELINE OPERATOR.
