A good sign that cleanup and restoration work is succeeding is with the removal of beneficial use impairments. Beneficial use impairments are designations given by the International Joint Commission representing different types of significant environmental degradation. As cleanup work is completed, and monitoring demonstrates sufficient environmental health improvements, BUIs can gradually be removed. This AOC has removed four BUIs and has five more to eliminate. See the list below. Once all BUIs are removed, the process of delisting the AOC can begin.
