Authorities say a hole in a western Minnesota pipeline caused a spill of about 8,400 gallons of diesel fuel, some of which found its way into a drainage ditch.

The Star Tribune reports that the incident happened Wednesday night near Cottonwood. A statement from the Yellow Medicine County Sheriff’s Office says the fuel escaped from “a small hole” in the Magellan Midstream pipeline, which is 8 inches in diameter.

The company says about 75 people, including emergency responders, federal, state and local regulators, cleanup experts, excavators and Magellan employees were at the site helping with cleanup and investigation.

One minor injury was reported, to a worker involved in the cleanup.
