Source Category Survey: Starch Manufacturing Industry

摘要

This report documents a study assessing the need for new source performance standards (NSPS) for the starch manufacturing industry. This industry is basically contained in SIC 2046, Wet Corn Milling, and includes the manufacture of corn starch, corn oil, corn syrups, wheat starch, wheat gluten (protein), potato starch, and by-product animal feeds. Starches can also be refined to produce ethanol alcohol for gasohol. Information and assessments concerning the products, processes, product uses, plants, historical statistics, and growth potential of the industry are presented. Air pollution emissions are identified and quantified as feasible with the limited data. Animal feed and starch dryers are the major sources of particulate emissions. Present methods of air pollution control and their effectiveness are examined. State regulations applying to the industry are summarized. Based on the estimated industry growth in new sources and the emission reduction attainable using the best available control, an estimate of the total emission reduction achievable through a NSPS is presented.
