Homes were evacuated for a short time due to a fire at the Valero Renewables Plant in Bloomingburg, northeast of Washington Court House.
The fire in a silo broke out Monday afternoon and continued into the night. It was still smoldering on Tuesday.
The Washington Court House Fire Department evacuated a 1,500-foot area around the plant as a precaution, including several homes.
The blaze burned for hours. A special group that specializes in assessing these types of fires was flown in from Texas by the company.
Firefighters say they are still not sure what caused the Fayette County fire or how much damage it caused. They must wait until they know it is safe to go inside and check out the situation.
Workers returned to their jobs at the plant on Tuesday morning.
Firefighters remain on standby in case the fire gets out of control, but officials say that’s unlikely.
No injuries were reported due to the blaze.
