Federal Guidance for Standards in the Great Lakes System
The Water Quality Guidance for the Great Lakes System was issued in 1995. It established minimum standards, antidegradation policies, and implementation procedures for waters of the Great Lakes system. This includes special requirements for bioaccumulative chemicals of concern. The eight Great Lakes states were required to adopt water quality standards as protective as these requirements within two years (by 1997).
