Cause detail: ON FEBRUARY 28, 2022, A CENTURION PIPELINE L.P. (CPL) EMPLOYEE WAS DRIVING NEAR THE RIGHT-OF-WAY (ROW) AND DISCOVERED A LEAK ON CPL'S ECTOR WEST TRUNK LOCATED NEAR CPL'S ECTOR STATION THAT IS LOCATED IN ECTOR COUNTY. CPL DETERMINED THE LEAK WAS A PINHOLE ON THE ECTOR WEST TRUNK 8'' PIPELINE. ONE (1) BARREL OF CRUDE OIL WERE RELEASED AND RECOVERED DURING THE PROCESS. NO INJURIES, FATALITIES OR FIRES WERE ASSOCIATED WITH THIS INCIDENT. CPL'S INVESTIGATION IS STILL PENDING AND A SUPPLEMENTAL REPORT WILL FOLLOW UPON THE COMPLETION OF THE INVESTIGATION. THE SUPPLEMENTAL REPORT WILL INCLUDE THE ROOT CAUSE OF THE ACCIDENT AND ASSOCIATED P&M MEASURES. SUPPLEMENTAL FINAL REPORT FILED APRIL 25, 2022: DURING THE ROOT CAUSE FAILURE ANALYSIS (RCFA) OF THE ECTOR WEST TRUNK (ECTOR HOLT) 8" PIPELINE, CPL IDENTIFIED LOCALIZED PITTING DUE TO EXTERNAL CORROSION RESULTING IN A THROUGH-WALL PIT AT THE 7 O'CLOCK POSITION. UPON EXCAVATION, CPL DISCOVERED AN UNKNOWN PIPE CROSSING AT THE LEAK SITE. CPL ALSO DISCOVERED THAT THE ECTOR HOLT PIPELINE IS CONSTRUCTED WITH SCREW AND COLLAR CONNECTIONS AND FOUND DEBRIS ADJACENT TO THE PIPE AT THE LEAK LOCATION. CPL DETERMINED THE LEAK WAS CAUSED BY EXTERNAL CORROSION DUE TO CATHODIC PROTECTION (CP) INTERFERENCE FROM THE UNKNOWN PIPE CROSSING. THE SCREW AND COLLAR CONNECTION AND THE PRESENCE OF DEBRIS NEXT TO THE PIPE CONTRIBUTED TO THE CORROSION. CPL REPLACED THE DAMAGE SECTION WITH APPROXIMATELY 70 FEET OF PIPE COATED WITH FUSION BOND EPOXY (FBE) TO PREVENT FURTHER INTERFERENCE AND DETERMINED NO FURTHER ACTIONS ARE NEEDED.
