| Abstract | We conducted 16 ambient sampling events between August 1998 and August 1999 at a commercial feedyard in the Texas High Plains. We operated Federal Reference Method PM10 samplers and high-volume samplers upwind and at the downwind fence line of a 12-corral test area. Six of the corrals were stocked at a typical cattle spacing of 13.9 m hd, and the remaining six corrals were stocked at a nominal spacing of 7.0 m hd. Sampler locations were oriented with respect to the prevailing SSW winds so as to minimize the likelihood of crosscontamination. Sampling events spanned 6to 24-hr intervals, as dictated by local weather conditions, in order to capture daily average effects and diurnal effects. We inferred the net emission of fugitive PM10 from the corral surface from the net (downwind-upwind) concentrations. The sampling data suggest that doubling the stocking density in cattle feedyards may reduce fugitive TSP and PM10 emissions from the corral surface by up to 29%, but average reductions of 5-20% or less are more likely in semi-arid climates. By itself, stocking density manipulation appears to have limited potential for control of particulate matter emissions from cattle feedyards, but it may represent a rational component of a dust-control regime involving additional management practices. |
