Technical Abstract: Since 2005, the Environmental Protection Agency (EPA) has attempted to regulate air emissions from confined animal feeding operations (CAFOs). These laws directly affect the poultry industry, which makes up approximately half of all CAFOs. The adaptation of these standards has been met with resistance by the poultry industry since the EPA has not developed a consistent or accurate way to determine emissions from poultry facility houses. Actual emissions from poultry houses vary greatly from house to house and depend largely upon the current climate, number of birds, age of the birds, and the feed used. Emission rate estimates are determined by multiplying the concentration of pollutants measured with ambient samplers inside the poultry house by the ventilation rate of the house. Ventilation rates are determined separately from the concentration. The data collected from these ambient sensors varies greatly from one study to the next. A major concern with these ambient sensors is that they do not measure pollutants at the source of emission into the environment, i.e. the ventilation fans of poultry houses. This presentation summarizes the development a semi-autonomous multi-point isokinetic sampling system to measure PM emissions from poultry house ventilation fans directly. This method eliminates the uncertainties associated with determining the emission concentration and ventilation rate separately.
