Incident Narrative

THE RELEASE WAS DUE TO ICE THAT FORMED IN A 1.5 INCH GLOBE VALVE. THE ICE FORMED DUE TO UNUSUALLY COLD AMBIENT TEMPERATURES. THE VALVE WAS LOCATED ON A DEHYDRATION UNIT AND WAS PART OF THE WATER DRAIN SYSTEM. WHEN THE VALVE WAS LAST CLOSED, THE PRESENCE OF THE ICE ALLOWED THE VALVE TO SEAL. DURING THE REGENERATION CYCLE OF THE DEHYDRATION UNIT, THE TEMPERATURE INCREASED AND MELTED THE ICE. WITH THE ICE MELTED, THERE WAS NO LONGER A SEAL AND PROPYLENE WAS RELEASED THROUGH THE VALVE. 3/13/2013 - UPDATED PER PHMSA REQUEST.
