Section 106.85. Determination of the necessity for water quality-based effluent limitations.

 

(1)  The department shall determine the need for chloride water quality-based effluent limitations for point source discharges whenever the discharges from the point sources contain chloride at concentrations or loadings which do not, as determined by any method in this section, meet the applicable water quality standards specified in chs. NR 102 to 105 .

(2)  When considering the necessity for water quality-based effluent limitations, the department shall consider in-stream bio-survey data and data from ambient toxicity analyses whenever the data are available.

(3)  When considering the necessity for chloride water quality-based effluent limitations, the department shall compare the upper 99th percentile of available representative discharge concentrations to the calculated limitations, pursuant to s. NR 106.05 (4) .
