NR 228.12 NR 228.12 Standards of performance. The following effluent limitations for all or specific subcategories when applied in accordance with s. NR 228.06 establish the quantity or quality of pollutants or pollutant properties which may be discharged by a facility which is a new source subject to the provisions of this chapter:

NR 228.12(1) (1) The pH of all discharges shall be within the range of 6.0 to 9.0.

NR 228.12(2) (2) The temperature of all discharges shall not exceed inlet temperatures by more than 3°C (5.4°F).

NR 228.12(3) (3) The daily maximum limitation for suspended solids is set forth in table 1.

NR 228.12 Note Note (1) Limitations are for suspended solids in lbs/1000 lbs or kg/1000 kg of product except for subcategory (3) for which limitations apply to concentrations in the runoff discharge.
