The document presents information on emissions of volatile organic compounds (VOC) from solvent extraction processing facilities in Shelby County, Tennessee. Information is presented on the soybean and cottonseed oil extraction industry, emissions from solvent extraction plants, emission control techniques, and the costs of reducing emissions. Sources of information include: an inspection at a soybean processing plant, a background document prepared by the Illinois Pollution Control Board, EPA publications, literature from the National Soybean Producers Association (NSPA) and National Cottonseed Products Association (NCPA), and discussions with industry representatives. The control measures described in the document represent the presumptive norm or reasonably available control technology (RACT) that can be applied to existing soybean and cottonseed processing plants. Reasonably available control technology for solvent extraction plants consists of efficient operation of the mineral oil scrubber and desolventizer-toaster, and good engineering practices (e.g., repair of leaking equipment).
