    3. Facility description

    The Agri-Energy LLC (Facility) is located at 502 Walnut Ave in Luverne, Rock County, Minnesota. Agri-Energy LLC produces fuel ethanol, isobutanol and Distiller's Dried Grain and Solubles (DDGS) from corn. Annual production limits are 26.000 million gallons of ethanol and/or isobutanol with an annual grain throughput of 300,000 tons per year of corn and 188,889 tons per year of dry distiller's grains with solubles (DDGS). Pollutants emitted include volatile organic compounds (VOC), particulate matter (PM), particulate matter smaller than 10 microns (PM10), particulate matter smaller than 2.5 microns (PM2.5), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), hazardous air pollutants (HAP) and greenhouse gases (GHG). Sources of emissions from the facility include grain receiving and handling, fermentation, distillation, DDGS production, dry fractionation processes, storage and handling, product and denaturant storage and loadout, and leaks from piping connections. The facility employs a thermal oxidizer (RTO) to control VOC emissions from DDGS drying, fermentation and distillation processes. Wet scrubbers also control emissions from the fermentation and distillation processes. The facility employs baghouses to control particulate emissions. The large product storage tanks are equipped with internal floating roofs to control VOC. The ethanol loadout rack for trucks is equipped with a vapor recovery system which vents to an RTO to control VOC. Emissions from equipment leaks are controlled through an inspection and maintenance program. Agri-Energy proposes to install additional equipment in order to increase isobutanol production while simultaneously producing ethanol. Agri-Energy will both modify some control equipment and install new equipment. New equipment will initially vent to the existing scrubbers; however, this equipment will eventually route to proposed new scrubbers once they are installed. Agri-Energy proposes the ability to bypass emissions to the RTO by venting fermentation and distillation processes to the atmosphere after control by each respective scrubber. Normal operation would be to have the RTO control in series with the fermentation and distillation scrubbers. Agri-Energy also proposes raising some emission limits for certain units including the RTO. Agri-Energy is also removing the use of propane fuel onsite. A separate major amendment is included to install equipment for a dry fractionation process. This involves the installation of new equipment including but not limited to fractionation units, separation units, conveyors, surge and storage bins, two dust collectors and baghouse. This permit action also includes an administrative and major amendment, both for a test extension on VOC (administrative) and VOC, PM and PM10 (major) for the RTO. This performance test has since been conducted.
