Along with these changes, all of the engineering planning that was completed to this point was not usable to address the changes in the treatment plant. WLA was retained to develop a facility plan, complete final design to address the new permit limitations and provide assistance with regulatory and funding coordination. New ammonia limits for year-round discharges were being proposed by the NDEQ that included a summer effluent limit of 0.64 mg/L, and limits for spring and winter.
