Incident Narrative

ON APRIL 3, 2024, DENBURY'S CONTROL CENTER (DCC) WAS NOTIFIED FROM A LOCAL DISPATCH OPERATOR THAT A RESPONDING FIRE DEPARTMENT WAS ON-SITE NEAR DENBURY'S LAKE CHARLES PUMP STATION AND WAS WITNESSING A SUSPECTED LEAK FROM THE STATION. ONCE DENBURY CONFIRMED THE LEAK, DCC SHUT DOWN THE SYSTEM AND CLOSED THE CLOSEST REMOTELY OPERATED UPSTREAM AND DOWNSTREAM VALVES. RESPONDING PERSONNEL CLOSED THE MANUAL ISOLATION VALVE FOR THE LAUNCHER ON-SITE, WHICH STOPPED THE RELEASE. LOCAL EMERGENCY RESPONDERS CONDUCTED A VERY EFFECTIVE RESPONSE IN LINE WITH PHMSA AND NATIONAL STATE FIRE MARSHAL GUIDANCE. THERE WERE NO REPORTS OF INJURIES OR SIGNIFICANT IMPACTS. ON APRIL 7, 2024, DENBURY PROVIDED PHMSA WITH ITS DETAILED PLAN TO REMOVE THE PIG CLOSURE AND REPLACE IT WITH A BLIND FLANGE. THIS REPAIR WAS DESIGNED TO REMOVE THE PIECE OF EQUIPMENT THAT FAILED, EFFECTIVELY ELIMINATING THE RISK OF A SIMILAR FAILURE ON THE LAUNCHER TRAP. AFTER PHMSA REVIEWED THE PLAN, DENBURY SUCCESSFULLY EXECUTED IT. DENBURY SUBMITTED ITS RE-START PLAN FOR THE LAKE CHARLES PUMP STATION ON APRIL 10, 2024. UPON PHMSA'S REVIEW AND ISSUANCE OF A NO-OBJECTION, DENBURY SUCCESSFULLY RESTARTED THE LAKE CHARLES PUMP STATION ON APRIL 11, 2024. PLEASE NOTE: ALTHOUGH THERE WERE NO EVACUATIONS, DENBURY ANSWERED QUESTION D11 WITH ""10 RESIDENTIAL BUILDINGS AFFECTED (EVACUATED OR REQUIRED REPAIR)"" BECAUSE THERE WERE 10 STRUCTURES WITHIN THE AREA COVERED BY THE 1/4-MILE-RADIUS SHELTER-IN-PLACE ORDER ISSUED BY WARD 6 FIRE PROTECTION DISTRICT NO. ONE.
