A fire that is currently ongoing at a Knoxville, Tennessee recycling plant is producing a smoke plume that is large enough to be detected by radar.  Local news outlets (WVLT) are reporting that the fire could have been cause by a machine spark.  All 25 employees have safely been evaluated, but the fire is still burning and being picked up by radar.  More info to come when it becomes available. 

At aprox 5:30pm the Knoxville Fire Department reported that the fire was still burning and evacuations were still in place for the immediate area.
