FERGUS FALLS — A Fergus Falls ethanol plant has resumed producing ethanol after a fire last week.

Green Plains Otter Tail, a subsidiary of Green Plains Renewable Energy Inc., began producing ethanol Sunday. The plant was temporarily shut down after a fire in the plant’s dryer system on March 10.

Green Plains officials said the plant will produce “wet cake” — a byproduct of ethanol production that is sold as livestock feed — until the dryer system can be repaired. The company said those repairs might take two months.

The fire was traced to a hydraulic pump failure. No one was hurt.
