Truck carrying ammonium nitrate rolls over at Hibbing Taconite entrance

A tanker truck carrying about 40,000 pounds of ammonium nitrate rolled over as it was turning into Hibbing Taconite on Friday morning. None of the ammonium nitrate spilled; the truck driver suffered minor injuries.
The Dyno Nobel truck tipped just after 8 a.m. as the driver was turning from County Highway 5 into the Hibbing Taconite facility, according to a news release from mine owner Cliffs Natural Resources. The HibTac entrance is 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 the ammonium nitrate spilled from the tanker, and less than five gallons of fuel oil spilled from the truck.
The highway was closed as crews transferred the ammonium nitrate. As of midday, St. Louis County officials said 20 percent of the material had been pumped from the overturned tanker.
County officials said there were no evacuations in the wake of crash. The mine was continuing to operate normally, Cliffs reported. The mine access road is fairly long, and the rollover occurred about two miles from the production facility.
The cause of the crash remains under investigation.
