P.L. 92--500, The Federal Water Pollution Control Act Amendments of 1972, has provided two mechanisms for the control of water pollution from animal production facilities.

Nonpoint source controls, as established by State and area-wide water quality management programs, are to be developed around the concept of "Best Management Practices."
