Truck carrying ammonium nitrate rolls over
HIBBING — A tanker truck carrying more than 20 tons of ammonium nitrate rolled over Friday morning as it was turning into Hibbing Taconite. None of the ammonium nitrate spilled and the truck driver suffered only minor injuries.
The Dyno Nobel truck tipped just after 8 a.m. as the driver was turning from County Road 5 into the Hibbing Taconite facility, according to mine owner Cliffs Natural Resources. The HibTac entrance is in Balkan Township about two miles west of Chisholm and about four miles north of Hibbing.
Ammonium nitrate is an explosive material used in the blasting process at the mine, Cliffs said. None of it spilled from the tanker, and less than 5 gallons of fuel oil spilled from the truck. All leaks were contained by shortly after 9 a.m. with little environmental impact, officials said.
The driver, whose name was not released Friday, suffered minor injuries and was taken by ambulance to Range Regional Medical Center in Hibbing.
The highway was closed as Cliffs crews transferred the truck’s entire load of about 42,000 tons of ammonium nitrate to another tanker. Once complete, the wrecked tanker was righted on its wheels and was removed from the highway by 2 p.m.
The cause of the crash remains under investigation.
