Incident Narrative
"ON JULY 11, 2022, AT APPROXIMATELY 14:50 A NATURAL GAS RELEASE OCCURRED AT THE GLENARM COMPRESSOR STATION LOCATED IN SANGAMON COUNTY, ILLINOIS. THE NATURAL GAS RELEASE WAS DUE TO A FAILED O-RING IN THE SYSTEM THAT SUPPLIED DOME PRESSURE ON AN ESD BLOWDOWN VALVE. THE DOME LOST PRESSURE WHICH CAUSED THE BLOWDOWN VALVE TO FAIL OPEN. AT 15:08, A LOCAL OPERATOR ISOLATED AND CLOSED THE ESD VALVE, THE POWER GAS PRESSURE WAS STABILIZED, AND THE RELEASE WAS SECURED. THE DAMAGED O-RING WAS REPLACED WITH A NEW O-RING AND THE SYSTEM WAS PUT BACK INTO SERVICE. AT APPROXIMATELY 16:20, IT WAS CONFIRMED THAT THE UNINTENTIONAL GAS LOSS WAS AT 5.928 MMCF, WHICH EXCEEDED THE 3 MMCF REPORTING CRITERIA AND THE NRC WAS NOTIFIED AT 16:44."
