Incident Narrative
"ON 4/12/2021, AFTER PRODUCT MOVEMENT WAS SHUT DOWN, THE PIPELINE CONTROLLER NOTICED THE SUMP TANK CONTINUED TO BE FILLED AND CONTACTED LOCAL OPERATIONS TO INVESTIGATE. AT 6:45 AM, A TECHNICIAN ARRIVED AND DISCOVERED OIL OVERFLOWING FROM THE PROVER BOX AT BRYANT G SOUTH STATION. THE TECHNICIAN ISOLATED THE METER SKID AND THE LEAK WAS STOPPED. AT 8:00 AM, IT WAS DETERMINED THE RELEASE MET ACCIDENT REPORTING CRITERIA BASED ON THE ESTIMATED VOLUME OF CRUDE RELEASED. THE TRRC WAS NOTIFIED AT 8:48 AM, INCIDENT #2410. INVESTIGATION IDENTIFIED THAT A VALVE WAS UNINTENTIONALLY LEFT PARTIALLY OPEN, ALLOWING CRUDE OIL TO DRAIN FROM THE MAINLINE INTO THE PROVER LOOP AND THEN OVERFLOWED THE SUMP. THE INVESTIGATION COULD NOT CLEARLY IDENTIFY WHEN THE VALVE WAS LAST OPERATED OR BY WHOM. TO PREVENT RECURRENCE A LARGER DIAMETER DRAIN LINE SYSTEM HAS BEEN INSTALLED TO CAPTURE OVERFILL FROM THE PROVER BOX AND DIRECT IT TO THE SUMP. SOIL REMEDIATION HAS BEEN COMPLETED."
