Rochester, Minn. — Al-Corn Clean Fuel of rural Claremont in Dodge County is proposing to expand its ethanol plant production from 50 million to 130 million gallons per year of 200-proof ethanol.

As required by state rules, the Minnesota Pollution Control Agency (MPCA) prepared an Environmental Assessment Worksheet (EAW) on the proposal. The public may submit written comments on the Al-Corn worksheet until 4:30 p.m. on Sept. 14.

The expansion will also increase production of dried distillers grains to 350,000 tons per year, and corn oil to nearly 4 million gallons per year. Corn processing capacity will increase to about 47 million bushels per year.

The expansion will include installing a new natural gas combustion turbine with a duct burner for combined heat and power; replacing and relocating grain storage and handling equipment; expanding rail loading and unloading capabilities; adding equipment for additional fermentation, distillation, and product storage; and adding a natural gas-fired boiler and a grain dryer.

The EAW provides basic information about how a proposed project could potentially affect the environment, and helps determine whether an Environmental Impact Statement, a more comprehensive environmental review, is needed. 

The worksheet for this project is available on the MPCA’s Environmental Assessment Worksheet webpage. Comments, which must be in writing, should go to Karen Kromar, MPCA, 520 Lafayette Road N., St. Paul, MN 55155. Ms. Kromar can be reached by phone at 651-757-2508, fax at 651-297-2343 or by email at
