About 230,000 gallons of diesel fuel spilled from an overflowing holding tank at a Huntington refinery early Thursday.
The fuel leaked for nearly three hours after a worker mistakenly left a pump on at Gladieux Trading and Marketing Co., Vice President Rasik Raval said.
The fuel spilled into a containment area, and environmental inspectors have not found any places where it leaked into surrounding property or leached into groundwater, Huntington Fire Chief Matt Armstrong said.
The Huntington Fire Department asked several crews to stand by as Gladieux employees and contractors cleaned up the diesel fuel.
An employee was transferring fuel from one holding tank to another and forgot to turn the pump off about 3:30 a.m., Raval said. Control room workers didnt notice the error until shortly after 6 a.m.
Gladieux plans to institute better controls that will promptly alert workers before a tank overflows. Employees at the facility, at 4757 E. U.S. 24, will also have greater supervision and more training, Raval said.
Armstrong said the company and firefighters were prepared. Cleanup was expected to wrap up this morning. The fire department had trained at the refinery last fall in the event of just such an accident, he said.
