Officials are investigating what caused a small fire at the Sonoco paper mill in Hartsville Wednesday night.
The fire appears to have started on a wall, according to Hartsville Fire Chief Jeff Burr.
He says when firefighters got on scene, the fire was nearly out.
"The fire was 99% out when we got there. You know, Sonoco has its fire bri g ade. We just helped them double check everything before we left, " said Chief Jeff Burr.
Burr says they checked the roof to make sure the fire hadn't spread there.
There were two fires at Sonoco in 2011 that involved no major structural damage.
We will let you know when officials determine a cause on Wednesday night's fire.
