Incident Narrative
"ON APRIL 29, 2024 TGP EXPERIENCED A REPORTABLE UNPLANNED ESD AT COMPRESSOR STATION 25 DUE TO LIGHTNING IN THE AREA. ONE ESD VALVE IN THE YARD DID NOT CLOSE DUE TO AN OUTAGE ON THE 100-2 LINE. FUEL GAS TO VALVE WAS DISCONNECTED FOR OUTAGE AND WHEN THE ESD WAS TRIGGERED GAS WAS NOT ABLE TO GET TO THE VALVE TO OPERATE. AT CLEVELAND, POWER GAS IS NEEDED TO OPERATE THE VALVES. A SEPARATE ESD POWER GAS OPERATES THE ESD VALVES WHEN AN ESD IS ACTIVATED. THE VALVE DID NOT CLOSE AS EXPECTED BECAUSE THERE WAS NOT POWER GAS IN THE ESD. THE INVESTIGATION DISCOVERED THAT THAT THE ESD SYSTEM DESIGN DID NOT INCLUDE SENDING ESD POWER GAS INTO THIS VALVE. TGP IS INSTALLING THE CONNECTION TO SEND ESD POWER GAS. 28,100 MCF OF NATURAL GAS LOST. FIRE DEPARTMENT DID SHOW UP TO SITE BUT WAS NOT NEEDED."
