Odor Research Impacts
  • Review and Documentation of the Regulation of Livestock Odors on a State by State Basis – Dr. Lacey and Jarah Redwine
    Redwine and Lacey assembled a comprehensive review of state regulations for livestock odor. The last document of this type was published over 12 years earlier. Significant changes have occurred in odor regulation since that time and a summary and comparison for all 50 states was warranted. Presentation of this information at the 2nd Annual Conference on Agricultural Air Pollution resulted in a large number of requests for additional information from Ms. Redwine and Dr. Lacey.
  • A Proposed ASAE Standard for Determination Cotton Ginning Emissions – Dr. Parnell and Dr. Shaw and Mike Buser
   Mr. Buser is addressing the problems that have been encountered by a number of engineers working with SAPRA personnel in the permitting process of cotton gins. The SAPRA personnel do not understand the cotton gin emission system and typically make significant errors in the permitting of gins in their states.
  • Aerial Pollutant Emissions from Confined Animal Buildings – Dr. John Sweeten, Dr. Jacek Koziel, Dr. Bok-Haeng Baek.
   The project goal is to determine baseline emission rates for swine finish barns in Texas and evaluate the differences in emissions due to season of year, time of day, growth cycle of the animals, and building management. Texas A&M University has been continuously measuring emissions of NH3, H2S, CO2, PM-10, and odor from mechanically-ventilated, confined swine finishing houses since November 2002. The swine finishing houses are located nearly 100 miles from Texas A&M Agricultural Research and Extension Center in Amarillo, Information from this research will provide producers, technical assistance providers, regulators, and compilers of emission inventories with accurate baseline information.
