AFTER THE HURRICANE IT WAS BROUGHT BACK ONLINE. WHEN THE PRESSURE ON THE DISCHARGE HEADER REACHED 746PSIG THE DISCHARGE HEADER RELIEF VALVE VENTED PREMATURELY. THE SET PRESSURE WAS 758PSIG (102%). OPERATING PERSONNEL WERE ONSITE, HEARD THE RELEASE AND RESPONDED BY SHUTTING THE STATION DOWN. THE RELIEF VALVE RELEASED APPROXIMATELY 3424MCF NATURAL GAS, MEETING AND EXCEEDING THE 3000MCF REQUIRED FOR INCIDENT REPORTING. FURTHER INVESTIGATION DETERMINED THAT THE PILOT COULD NOT HOLD THE SET PRESSURE. BASED ON AN EVALUATION OF THE OVERPRESSURE PROTECTION (OPP) REQUIRED BY 49CFR 192 IT WAS DETERMINED THAT THIS DEVICE WAS REDUNDANT AND IT WILL NOT BE PUT BACK INTO SERVICE.\n\nPHMSA trend classification: not significant, not serious.\n\nPHMSA standardized cause: EQUIPMENT FAILURE — MALFUNCTION OF CONTROL/RELIEF EQUIPMENT.\n\nPHMSA indexed costs: $15,301 reported total cost, $12,354.078 in 1984 dollars, $18,017.982 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
