UNDERWOOD, N.D. — In honor of the 10th year of production for Blue Flint Ethanol, a celebration was thrown on June 28 and drew a crowd of 200 workers, industry leaders and government officials.

Jeff Zueger is chief executive officer for Midwest AgEnergy Group LLC. Midwest AgEnergy owns Blue Flint Ethanol, LLC, which started production in February 2007, and later Dakota Spirit Ethanol, Spiritwood, N.D., which started production in 2015.

Blue Flint initially was built for $95 million and was designed for 50 million gallons per year of ethanol production, using steam generated from a coal-fired electrical plant next door. The plant helped build a corn production industry for farmers in that region.
