5. Description of Event/Occurrence:
Employee was dispensing fuel from tank truck, 68C 4365, (equipped with three
separate storage tanks and dispensing systems) into underground fuel tanks at the
100-N fueling station. He placed the fuel dispensing nozzle into the 4" fill
spout of the service station tank, set the automatic shut-off and returned to his
truck to complete related paperwork while waiting for the tank to fill. The
nozzle did not shut off and the tank overflowed. The employee did not observe
the spillage until a passerby walked up to the truck to inform him of the
overflowing condition. The fuel truck driver immediately turned the nozzle off
manually. The passerby noted the fuel truck driver was in the truck attending
paperwork and .wearing radio headphones which may have'contributed to his
inattention to fueling activities. The spill was reported to N-Reactor
Operations Management and the Supervisor, Special Delivery Services. Initial
assessment of the spill area was done by N-Reactor Operations Management
personnel. Environmental Assurance was advised.
The employee then proceeded to manually fill the second underground tank with the
remaining fuel in the first tank of the truck. When that truck tank was drained,
he stored the hose and nozzle and proceeded to continue filling the second
service station tank from the second truck tank with a different nozzle. He set
the new nozzle on automatic and stepped back to remain clear of the fumes.
