3. Facility description
The Bushmills Ethanol (Facility) is located at 17025 Highway 12 NE in Atwater, Kandiyohi County, Minnesota. Bushmills Ethanol (Bushmills) is a drymill ethanol production facility located west of Atwater, MN on U.S. Highway 12. The facility currently produces Dried Distiller's Grain with Solubles (DDGS), wetcake and corn oil as coproducts. Bushmills is permitted to produce annually up to 100 million gallons of undenatured ethanol and 330,000 tons of DDGS. The facility is authorized to receive up to 1.075 million tons of grain per year, and load out up to 7.5 million gallons of denaturant. Particulate emissions from the truck and rail unloading area, elevators, conveyors, and grain bins exhaust through a negative pressure ventilation system, which continuously pulls air from these sources through a baghouse. Grain from the surge bin feeds into a hammermill. A conveyor moves the milled grain from the hammermill into the blender. The blender mixes the milled grain with water to start the ethanol production process. The air exiting the hammermills routes to a baghouse. There are two baghouses to control particulate emissions from all hammermills. The hammermills are located indoors. The facility is permitted for one RTO which provides VOC, CO, PM, PM10, PM2.5 and HAP emission control by combustion. Some vents from distillation, as well as other process tank vents are tied to the centrate blower. The gas coming off the fermenters flows up through a bed of stainless steel structured packing inside a direct contact scrubber. Water flows down through the bed. A continuous blowdown of this water flows back into the process stream. CO2 and other noncondensing gases leaving the scrubber are vented to the atmosphere. The gas coming off the centrate blower and prefermentation equipment, with exceptions, vents to the RTO. Direct venting to the atmosphere from the cook water tank, liquefaction tanks, and slurry tank 2 are authorized by this permit. The beer resulting from the fermentation runs through a continuous vacuum distillation system to remove and rectify the ethanol. The vapor outlet of the distillation column gets piped directly to a set of condensers that discharge liquid ethanol to the 190proof tank. From the 190proof tank, the liquid passes through a molecular sieve and then to the 200proof condenser and stored in a 200proof storage tank. The gases leaving the condensers, evaporators, receiver tanks, centrate tanks, dewatering devices and corn oil tanks are typically vented to the RTO prior to venting to the atmosphere. Direct venting to the atmosphere from the thin stillage tank, whole stillage tank and syrup tank are authorized by this permit. DDGS dries in a rotary drum dryer system. Exhaust from the dryers passes through the RTO. DDGS is conveyed and dropped into an enclosed building. DDGS is removed from the pile by front end loaders, then dropped into a drop pit and conveyed via an elevator and conveyor for load out. These conveyors and elevator are vented to a baghouse. The handling operations in the storage building are not aspirated to controls. DDGS is loaded into trucks/railcars with the exhaust air passing through a baghouse prior to venting to the atmosphere. The product gets pumped daily from the 200proof tank or to one of the storage tanks. Natural gasoline may be added as denaturant via inline blending. Internal floating roofs control air emissions from the ethanol product tanks. Each tank also has a fire valve, a level gauge, and overfill protection. To provide process electricity and steam, Bushmills is authorized to operate 2 natural gasfired combustion turbines with duct burners. Ethanol truck loading emissions are flared during standard operation. The 300hp fire water pump engine is an emergency unit defined to operate less than 500 hours on a 12month rolling sum basis. Ethanol rail cars only handle ethanol and denatured ethanol final product. Emissions from the three rail loading racks are not required to be controlled. Bushmills uses a flare to control emissions from truckloading operations. A total of two truck transfer areas currently exist.
