HARVEST MIDSTREAM COMPANY

Incident Narrative

"DURING ONGOING CONSTRUCTION AT THE BURWOOD E-5 STATION, A PRESSURE TRANSDUCER WAS TEMPORARILY RELOCATED TO FACILITATE THE WORK. SHORTLY AFTER NORMAL OPERATIONS RESUMED, THE 1"" POLY TUBING CONNECTED TO THE TRANSDUCER FAILED, RELEASING APPROXIMATELY FIVE GALLONS OF CRUDE OIL ONTO THE EQUIPMENT AND INTO THE BURWOOD CANAL BELOW. HARVEST PERSONNEL PROMPTLY ISOLATED THE LEAK, MADE THE NECESSARY INTERNAL AND EXTERNAL NOTIFICATIONS, AND INITIATED CLEAN-UP EFFORTS. AN INVESTIGATION IS UNDERWAY, WITH A ROOT CAUSE ANALYSIS TO FOLLOW. PRELIMINARY FINDINGS SUGGEST THAT IMPROPER EQUIPMENT WAS INSTALLED FOR THE OPERATION. THE ROOT CAUSE OF THIS INCIDENT WAS THE FAILURE TO FOLLOW THE FORMALIZED PROCESS FOR EVALUATING AND APPROVING TEMPORARY MODIFICATIONS IN PRESSURIZED SYSTEMS THAT ARE NOT ""LIKE AND KIND."" AS A CORRECTIVE ACTION, ALL TEMPORARY MODIFICATIONS WILL NOW REQUIRE AN ENGINEERING REVIEW AS PART OF THE MANAGEMENT OF CHANGE (MOC) PROCESS. ADDITIONALLY, PERSONNEL WILL RECEIVE TRAINING, AS NEEDED, ON THE IMPORTANCE OF USING PRESSURE-RATED MATERIALS IN ALL APPLICATIONS DURING MAY 2025. IMPROVED COMMUNICATION AND OVERSIGHT BETWEEN CONSTRUCTION, OPERATIONS, AND E&I TEAMS WILL FURTHER ENSURE PROPER IMPLEMENTATION AND ADHERENCE TO STANDARDS, REDUCING THE RISK OF SIMILAR INCIDENTS IN THE FUTURE. THROUGH THESE CORRECTIVE ACTIONS, HARVEST AIMS TO ENHANCE OPERATIONAL INTEGRITY, STRENGTHEN PROCEDURAL COMPLIANCE, AND PREVENT RECURRENCE OF SIMILAR FAILURES."
