UPDATE: As of 3:20 p.m., the S.C. Highway Patrol reports the on-ramp has reopened.
At 10:30 a.m. a dump truck carrying the sewage overturned in the middle of a southbound on ramp, dumping its load and blocking southbound traffic turning on the Interstate for several hours.
“It’s non hazardous but you do smell a heavy ammonia smell,” Lt. Leff Nash of the Flint Hill Fire Department said.
Nash said the processed sewage was non-toxic and not flammable. “It creates a big mess,” Nash said.
The truck was transporting the waste, commonly known as sludge, from a waste treatment plant in Charlotte to a lined landfill in the Columbia area.
Our news partner WSOC-TV reports the driver was driving too fast when he made the tight turn onto the highway.
No injuries were reported.
