Storage in an animal waste disposal system requires long-range planning of spreading operations with respect to land availability, storage capacity, value of plant nutrients in the wastes, cost, and other parameters. One of the foremost problems in land disposal of animal wastes is the emission of malodorous gases from these wastes and their transport into populated areas through the atmosphere. Therefore, malodors are a constraint on land spreading of animal wastes. The objectives of this study were: to analyze systems which interact with a storage and land disposal system, and to identify relevant interfaces and variables; to develop and test a mathematical model describing the storage of animal wastes and their subsequent disposal on agricultural lands in a timely manner; and to apply the results of atmospheric diffusion studies to delineate the odor nuisance potential of animal wastes. A scheduling model was developed for studying long-term scheduling decisions for removing waste from storage and spreading it on agricultural lands. This was modeled as a multistage decision process, dynamic programming techniques were used to find the optimal disposal schedule (times and quantities). The maximum quantity which can be disposed in each time period is constrained by storage capacity, quantity of waste generated, and land area available for spreading the wastes. Tank wagon capacity, operation times, and cost of labor were not as significant as fixed storage cost, but were sufficiently important to merit consideration in the design and operation of the system. Land availability and nutrient effectiveness as a function of time were also significant. An air quality model was developed for evaluating the odor nuisance potential of animal wastes as a constraint on land spreading operations. The atmospheric diffusion equations developed by Sutton for predicting the downwind concentration of gaseous effluents from point and finite line sources were utilized in the model. The principal parameters affecting the downwind ground level concentrations of malodors are emission rate, wind speed, diffusion coefficients and turbulence index. Livestock production units which employ land disposal have the opportunity to contribute to malodorous air pollution abatement by performing animal waste handling and field spreading operations when meteorological conditions exist which favor good atmospheric diffusion.
