  • A New Dispersion Modeling Procedure (FTAM) for Predicting Downwind Concentrations of PM10 from Low-Level Point Sources (LLPS) [LLPS include Cotton Gins, Grain Elevators, Feed Mills, etc.] – Dr Shaw, Dr. Brad Fritz, Linda Williams, Greg Zwicke, and John Wanjura
   The Industrial Source Complex Short Term, version 3 (ISCST3) model is the EPA recommended dispersion model for predicting downwind concentrations from sources. The problems we have encountered using ISCST3 is that it over-estimates downwind concentrations. We have conducted an in-depth analysis and have learned that a correction can be made in the science that will more appropriately account for wind direction changes in the ISCST3 model. The resulting downwind estimates of the 24-hour concentrations are reduced by a factor of 2.5. If we can get EPA approval to use this approach, the resulting impact upon SAPRA permitting of cotton gins, grain elevators and feed mills will be significant.
  • Exhaust Emissions from Engines Fueled by Cottonseed oil Biodiesel– Sergio Capareda

   Engine dynamometer tests were made using various mixtures of cottonseed oil biodiesel. The engine performance curves and complete exhaust emissions (NOx, Sox, PM and VOC) were measured to generate new information on engine emissions using blends of biofuels.
