FIELD MANAGEMENT WAS NOTIFIED. PER DENBURY'S OM0213, THE LEAK WAS CLASSIFIED AS NON-HAZARDOUS AND SCHEDULED TO BE REPAIRED AS SOON AS PRACTICAL. THE DENBURY CONTROL CENTER DID NOT RECEIVE AN ALARM OR IDENTIFY ANY LOSS OF PRESSURE OR PRODUCT FROM THE LOCATION OF THE LEAK DUE TO THE SMALL SIZE OF THE LEAK AND IT BEING ON AN ISOLATED SECTION OF THE PIG RECEIVER PIPING. CONSIDERING THE VOLUME OF CO2 BEING RELEASED, DENBURY DETERMINED THIS LEAK TO BE NON-SIGNIFICANT, THEREFORE A NATIONAL RESPONSE CENTER (NRC) NOTIFICATION WAS NOT REQUIRED. DENBURY PERSONNEL ARRIVED ONSITE ON 10/17/2023 TO BEGIN REPAIRING THE LEAK. THE SYSTEM WAS RETURNED TO NORMAL OPERATION AFTER THE LEAK WAS REPAIRED ON 10/17/2023 AT 10:00.\n\nPHMSA trend classification: not significant, not serious.\n\nPHMSA standardized cause: EQUIPMENT FAILURE — THREADED CONNECTION/COUPLING FAILURE.\n\nPHMSA indexed costs: $371 reported total cost, $156.751 in 1984 dollars, $386.029 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
