The purpose of this design document is to summarize and update mill process information and results from previous cycles and other studies, and to provide a rationale for the design of the Cycle Three program. Five elements of the EEM program will be discussed: fish survey, effects on the use of fisheries resources, invertebrate community survey, chemical tracers, and sublethal toxicological testing of process effluent. In addition, this design document includes a tentative schedule for execution of field surveys.
