3. Facility description The Heartland Corn Products (Facility) is located at 53331 State Highway 19 E in Winthrop, MN, Sibley County, Minnesota. The Heartland Corn Products (Facility) is a natural fermentation fuel ethanol production plant located at 53331 State Highway 19 E in Winthrop, MN, Sibley County, Minnesota. At the facility, corn is ground and mixed with water and enzymes, cooked, and then fermented in tanks. The resulting liquid is separated from the solids, and distilled to produce pure fuel‐grade ethanol. The pure ethanol is denatured with gasoline, and stored in tanks prior to shipping by truck or rail. Solids from the fermentation process are dried to produce Dry Distillers’ Grain with Solubles, which is sold for use in livestock feed. Permit Action 010 description: This permit action was a reissuance of the pt. 70 operating permit, and also included a major amendment to increase the (un‐denatured 200 proof) ethanol production limit from 103.9 million gallons per year to 120 million gallons per year.

The major amendment included in the reissuance also revised the paved road fugitive dust requirements, added a fire pump diesel engine to the permit (installed circa 2006 as part of a project authorized by permit No. 14300014‐005, but not included in that permit), provided flexibility to add, replace, and modify certain emission units, removed the Methanator Flares (because they were not operated), revised the permit modeling appendix due to recent modeling, and corrected errors and omissions in the Delta permit database. Permit Action 011 description: This permit action is a major amendment to add a combined heat and power unit with combustion turbine (EQUI 164) and duct burner (EQUI 165) to provide on‐site steam and electricity. The existing boilers will remain as a backup. The facility also proposes to increase ethanol production to 124.9 million gallons per year through process improvements. This production increase will not involve increases in grain throughput or DDGS output limits. All grain handling and DDGS loading/unloading operations at the East Plant will end once West Plant construction is completed. After construction, these operations will be at the West Plant only. The hours for these operations will be expanded from 10 (7AM‐5PM) to 12 hours (6AM‐6PM) per day. Fermenters #6 and #7 that were permitted but never built will be built and represented as EQUI 120 and EQUI 138. VRTO #1 will be replaced by a new VRTO #1 (EQUI 162), cooling towers will be relocated and a new Fermenter #6 (EQUI 161), DDGS Bin #3 (EQUI 163) and Corn Bin #7 (EQUI 166) will be added to the West Plant.

This permit action also includes a minor amendment to add a 2 million gallon storage tank for denatured ethanol (EQUI 75), and an administrative amendment for a 120‐day test extension.
