Abstract

Rules released by EPA in 2003 require beef feedlots defined as Concentrated Animal Feeding Operations (CAFO) to control rainfall runoff from their feedlots. The rules included verbiage that allowed for the design and use of “Alternative Technologies” and require that any “Alternative Technology” be modeled to show they are at the least as effective as traditional storage systems. Currently, in Iowa, many feedlots do not have waste handling systems capable of sufficiently controlling discharges. The traditional system being accepted for permit in Iowa is an ELG storage basin. The two technologies in this study are Vegetated Treatment Areas (VTAs) and Vegetated Infiltration Basins (VIBs) followed by a VTA.
