SITE SELECTION OF ANIMAL OPERATIONS USING AIR QUALITY CRITERIA

摘要

The establishment or determination of setback distances from animal production facilities can be accomplishedusing guideline approaches or by the use of dispersion models. Guidelines are used to determine setback distances based oncriteria such as empirical formulas based on animal units, animal housing system, physical size of operation, or similarparameters. The dispersion model method is a more robust tool that inputs specific airborne emissions, such as odor,ammonia, or pathogens, from the animal production site as well as weather conditions then estimates a concentration of thepollutant (odor, ammonia, etc.) downstream which can be used to establish a setback distance.
