Cause detail: ON NOVEMBER 28, 2022, A THIRD PARTY DRIVER INFORMED CENTURION PIPELINE, L.P. (CPL) OF A LEAK. THE CPL EMPLOYEE ARRIVED ON-SITE AT 07:45 AM AND CONFIRMED THE LEAK WAS NEAR CPL'S WASSON STATION - CET #13 LOCATED NEAR DENVER CITY, IN GAINES COUNTY, TEXAS. TWO (2) BARRELS OF CRUDE OIL WERE RELEASED AND RECOVERED DURING THE PROCESS. CPL REMEDIATED THE CONTAMINATED SOIL ON SITE. NO INJURIES, FATALITIES OR FIRES WERE ASSOCIATED WITH THIS INCIDENT. CPL'S INVESTIGATION DETERMINED THAT INCORRECT OPERATIONS BY THIRD PARTY CAUSED THE LEAK. THE ROOT CAUSE OF THE LEAK WAS THAT A THIRD PARTY TRUCK DRIVER OPERATING THE VALVES FOR UNLOADING DID NOT CLOSE THE BALL VALVE AFTER COMPLETING THE TASK TO FILL THE TANK. A CONTRIBUTING FACTOR TO THE LEAK WAS THAT THE CHECK VALVE ON THE LINE WAS NOT FULLY SEALED DUE TO SOLIDS THAT HAD BEEN FOUND ON THE SEAL. THIS ALLOWED THE FLOW TO SLOWLY LEAK THROUGH THE VALVE AND INTO THE CATCH BASIN WHICH OVERFLOWED. THE THIRD PARTY TRUCKING COMPANY HAS BEEN CONTACTED FOR EDUCATIONAL PURPOSES TO PREVENT FURTHER INCIDENTS. NO FURTHER ACTIONS ARE REQUIRED.
