“Approximately 10 cars are fully engulfed resulting in heavy smoke in the area,” the Cass County sheriff said in a statement at 4:36 p.m., adding that local fire and hazardous material teams were battling the blaze. The sheriff said it was not yet clear how the collision had occurred.
Residents within 5 miles (8 km) to the south and east of Casselton were urged to evacuate to avoid contact with the smoke. Residents within 10 miles were asked to remain indoors.
Casselton City Auditor Sheila Klevgard said crews are pushing snow to contain the oil before it reaches a nearby creek.
