Multiple agencies responded to a structure fire at the Marquis Energy property in Hennepin early Wednesday afternoon.

Marquis Energy Communications Manager Allison Schwingle said in an email that the fire is contained and everyone is safe.

“The Marquis team appreciates all the local support from fire departments and first responders,” she said.

The fire involved the central maintenance building, a former steel mill building, at the facility.

“Local fire departments and emergency personnel are on site, and we are grateful for their quick response and support,” she said.

Schwingle said one minor injury was reported.

Corn deliveries and ethanol production are unaffected, as this incident did not occur at our ethanol facility, she said.

“The safety of our employees and community remains our top priority as we continue to work closely with first responders to manage the situation, Schwingle said.
