Fire investigators are working to figure out what sparked a fire that damaged part of the heating facility on the campus of Eastern Kentucky University in Richmond.
Firefighters were called to the scene just after 5 Thursday morning.
They say they quickly determined the fire was coming from the fly ash silo at the back of the Ramsey heat plant.
Firefighters say they worked with EKU Facility Services and the EKU Office of Environmental Health and Safety to handle the fire.
The silo held the waste product from the coal fired boilers used to heat buildings on the EKU campus. The heat had been turned off since April.
The Richmond Fire Department and EKU officials are working together to determine what caused the fire.
