THIS RESULTED IN A RELEASE OF 4,230 MCF OF NATURAL GAS. THE OPERATING PRESSURE NEVER EXCEEDED 1020PSIG AT THE STATION THUS, NEVER EXCEEDING THE MAOP IS 1050 PSIG. UPON INVESTIGATION, A GAS ANALYZER DESIGNED TO DETECT H2S AT THE DELIVERY POINT FAILED RESULTING IN A SHUTDOWN OF THE COMPRESSOR STATION. THE SHUTDOWN RESULTED IN AN INCREASE OF PRESSURE AND SUBSEQUENT ACTIVATION OF THE RELIEF VALVE CAUSING THE RELEASE OF NATURAL GAS TO ATMOSPHERE. THE RELIEF VALVE FUNCTIONED PROPERLY AS DESIGNED.\n\nPHMSA trend classification: not significant, not serious.\n\nPHMSA standardized cause: EQUIPMENT FAILURE — MALFUNCTION OF CONTROL/RELIEF EQUIPMENT.\n\nPHMSA indexed costs: $18,536 reported total cost, $13,937.348 in 1984 dollars, $20,364.908 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings.","truncated":false,"body_characters":1564}
