Regulations set out by the Agricultural Operation Practices Act (AOPA) dictate a minimum setback distance of 100 m (328 ft) between livestock yards, including confined feeding livestock areas, and any water source. However, this applies only to facilities built after AOPA came into effect in 2001. For instalments built prior to 2001, these are considered legal as there were no minimum setback distance regulations for barns and corrals. This is the process commonly known as "grandfathering."
