Incident Narrative
"ON JANUARY 17, 2018 GASOLINE WAS CONFIRMED TO HAVE BEEN RELEASED FROM AN EXTERNAL FLOATING ROOF (EFR) TANK ROOF DRAIN SYSTEM AT 19:35 CST, AFTER THE SMELL OF GASOLINE WAS REPORTED AT 19:25 CST. THE 3 INCH ROOF DRAIN SYSTEM IS A GRAVITY FED SYSTEM TO DRAIN WATER OFF THE TOP OF AN EFR. THE DIRECT CAUSE OF THE RELEASE WAS A CRACK IN THE ROOF DRAIN HARD PIPE THAT CONNECTS TO THE EXTERNAL FLOATING ROOF SUMP. THE CRACK IN THE PIPING WAS CAUSED WHEN THE TANK WAS EMPTY, ON LOW LEGS, AND FREEZING TEMPERATURES CAUSED AN ICE PLUG IN THE GRAVITY DRAIN SYSTEM PIPE. WHEN THE TANK WAS PLACED IN BACK IN SERVICE, PRODUCT WAS RELEASED FROM THE CRACK IN THE EFR ROOF DRAIN PIPE SYSTEM. ALL THE PRODUCT THAT WAS RELEASED WAS TOTALLY CONTAINED INSIDE THE TANK DIKE OF THE SECURED GLENPOOL TANK FARM. ANY IMPACTED SOIL WAS TESTED AND PROPERLY MANAGED. FIFTY BARRELS OF FREE PHASE PRODUCT WAS RECOVERED, AND THE REMAINING 32 BARRELS WAS CALCULATED EVAPORATION LOSSES."
