5 Permit issued: [month day, year] Permit expires: [month day, year] Page 5 of Facility description Cargill AgHorizons (Cargill) supports Green Plains, Fairmont LLC. (Green Plains) in providing grain required to operate an adjacent fuel grade ethanol production plant in Fairmont, Minnesota. Cargill and Green Plains are considered one source for Prevention of Significant Deterioration (PSD), Part 70 and Part 63 NESHAPs; therefore they must consider the combined emissions from both facilities when determining regulatory applicability. Green Plains has a maximum design capacity of million gallons of undenatured ethanol or million gallons of denatured ethanol on an annual basis. Cargill is authorized to receive up to 43,703,704 bushels of grain per year. The facility has a 1,333,678 bushel storage capacity. Grain receiving and handling operations generate PM/PM10/PM2.5 emissions which are fabric filters. An enclosed conveying system transports the grain from the silos to the ethanol facility for processing and is baghouses. The Cargill grain elevator and Green Plains facility will jointly have emissions less than 250 tons per year for each criteria pollutant. Therefore, the combined facility of Cargill and Green Plains is a minor source with respect to New Source Review.
