ELKTON — An anhydrous ammonia leak caused Interstate 90 to be shut down and some homes to be evacuated Monday night.
Mower County Sheriff Terese Amazi confirmed two 1,000 gallon anhydrous ammonia tanks leaked at the grain elevator on County Road 7 south of Elkton around 4 p.m. As of 6:25 p.m., the tanks were shut off, but an anhydrous cloud was still hovering.

Sometime around 5:30 p.m., law enforcement closed Interstate 90 east of the Elkton exit — 650th Avenue. Amazi urged motorists to avoid the area.
“Stay off the interstate if you can,” she said.
The interstate has since reopened.
Though the leak started south of Elkton, the cloud had moved north to Interstate 90, and Amazi said it wasn’t dissipating in the low winds.
Shortly after 5:30 p.m., Chief Deputy Mark May confirmed that there was a large anhydrous cloud hovering near the interstate, but the two 1,000 gallon tanks that leaked were being shut off.
Amazi didn’t know how long Interstate 90 would be shut down, and said crews would be taking readings. Amazi said she hasn’t experienced an event like this in her more than 27 years on the force.
“I haven’t had one of these in my career,” she said.
Dexter and Grand Meadow Fire Departments also responded to the scene.
The tanks were about 85 percent full when they started to leak, according to reports. A one-mile perimeter was set up around Elkton earlier in the evening, and homes were being evacuated near the incident.
At one point, officials thought the leak was four 1,000 gallon tanks of the farming chemical, which is a widely used source of nitrogen fertilizer. The tanks were reportedly owned by Cenex Harvest States.
