This publication summarizes the current state of the art on runoff control from beef, dairy, swine, sheep, and turkey feedlots. Amendments to the Federal Water Pollution Control Act have established a goal to eliminate pollutant discharges into the Nation's waterways by 1983. Sections on the legal implications of feedlot-runoff control, quantity and quality of runoff, runoff-control facilities and their applications, and disposal of the controlled runoff are included.
