Crews were called to an early morning fire at the Valero ethanol plant in Montgomery County Monday.

After 1 a.m., a call came in about a fire at the Valero plant, just off of U.S. 231 near Linden. Firefighters from six departments responded to the plant just after 1:30 a.m.

Linden firefighters say the fire started in the dryer area which is on the west end of the facility.

Earl Heide from the Linden Fire Department said it took five hours to put out all of the hot spots. He said there is major damage to the west section of the plant.

Authorities said no one was injured in the incident.

State investigators are currently trying to determine the cause of the fire.
