Cause detail: ON APRIL 17, 2021, AT APPROXIMATELY 16:30 CST, AN EMPLOYEE OF TARGA RESOURCES REPORTED A POSSIBLE LEAK ON THE ELKINS SOUTH TRUNK 6" NON-REGULATED GATHERING LINE NEAR MIDKIFF, TEXAS IN UPTON COUNTY, TEXAS. TARGA RESOURCES RESPONDED TO A CALL FROM THE LANDOWNER REGARDING A POSSIBLE LEAK, AND NOTIFIED CENTURION PIPELINE LP (CPL) UPON DISCOVERING THE LEAK ORIGINATED FROM A CPL PIPELINE. CPL IMMEDIATELY DISPATCHED A COMPANY EMPLOYEE TO THE LOCATION. ON APRIL 17, 2021, AT APPROXIMATELY 17:27 CST, CPL RESOURCES ARRIVED ON-SITE AND DETERMINED THE SOURCE OF THE LEAK TO BE THE ELKINS SOUTH TRUNK 6" PIPELINE. CPL PROMPTLY ISOLATED THE LEAK AND BEGAN CLEAN UP EFFORTS. HOWEVER, FIVE (5) BARRELS OF CRUDE OIL WERE RELEASED. CPL REMEDIATED THE CONTAMINATED SOIL ON SITE. NO INJURIES, FATALITIES, OR FIRES WERE ASSOCIATED WITH THIS INCIDENT. DURING THE ROOT CAUSE ANALYSIS, CPL DETERMINED THE CAUSE OF LEAK TO BE INTERNAL CORROSION ATTRIBUTED TO LOW FLOW AND A PIPING CONFIGURATION THAT DOES NOT ACCOMMODATE MAINTENANCE PIGS. IN ORDER TO PREVENT RECURRENCE, CPL WILL EVALUATE THE NON-REGULATED, GATHERING PIPELINE TO DETERMINE IF PRODUCT THROUGHPUT SUPPORTS THE DEVELOPMENT OF A PERMANENT INTERNAL CORROSION MITIGATION PLAN THAT WILL PERMIT A SAFE, CONTINUED OPERATION. IF EXPECTED THROUGHPUT DOES NOT SUPPORT A REHABILITATION PLAN, CPL WILL PURGE AND IDLE THE ELKINS SOUTH TRUNK 6" PIPELINE. SUPPLEMENTAL FINAL REPORT FILED ON 05/18/2021: UPDATED PART A5 TO CORRECT A TRANSCRIPTION ERROR FOR LATITUDE FROM '32.52900' TO '31.52900.'
