Fire crews extinguished a fire at a small oil tank farm southwest of Wright on Friday, a Campbell County Fire Department official said. The five units from the department responded to the report of the fire at a storage tank battery about 10:15 a.m., put it out and cleared the area by early afternoon, training Chief Ron Smith said. There were no injuries, Smith said. The tank battery had six or seven tanks that can hold about 400 barrels, he said. A barrel is 42 gallons.
