Incident Narrative
TANK 108 ROOF DRAIN WAS OPENED TO DRAIN WATER FROM THE ROOF. THE OPERATION WAS CHECKED THROUGHOUT THE SHIFT, BUT A SMALL AMOUNT OF GASOLINE WAS OBSERVED COMING FROM THE VALVE WITH THE FINAL CHECK OF THE DAY. THE VALVE WAS CLOSED AND ABSORBENTS USED TO COLLECT GASOLINE THAT WAS RELEASED INSIDE THE TANK CONTAINMENT. IMPACTED ABSORBENTS WERE PROPERLY CONTAINED FOR DISPOSAL. MINOR AMOUNTS OF SURFACE SOIL COLLECTED AND PLACED IN DRUMS FOR DISPOSAL. ONCE THE TANK WAS REMOVED FROM SERVICE AND CLEANED IT WAS DETERMINED THAT THE ROOF DRAIN SYSTEM HAD ACCUMULATED ICE. THE FLEXIBLE JOINT CONNECTION INTERNAL TO THE TANK HAD BEEN DAMAGED WHICH ALLOWED PRODUCT TO ENTER THE ROOF DRAIN SYSTEM. THIS STYLE FLEXIBLE JOINT CONNECTION FOR INTERNAL ROOF DRAIN SYSTEM ON EXTERNAL FLOATING ROOFS (EFR) IS NO LONGER AN APPROVED INSTALLATION. MAGELLAN HAS ALSO PREPARED A LESSON LEARNED BULLETIN (LLB) TO BE DISTRIBUTED ACROSS OPERATIONS FOR PROPER WINTERIZATION OF EFR ROOF DRAINS. THE LLB WILL PROVIDE GUIDANCE TO MODIFY SITE SPECIFIC WINTERIZATION PROCEDURES. APPROXIMATELY 20 CUBIC YARDS OF SOIL WAS REMEDIATED SUPPLEMENTAL UPDATE: PART H NARRATIVE
