NR 276.07 Discharges from impoundments. NR 276.07(1)
(1) A process wastewater impoundment which is designed, constructed and operated so as to contain the precipitation from the 10 year, 24 hour rainfall event for the area in which such impoundment is located may discharge that volume of process wastewater which is equivalent to the volume of precipitation that falls within the impoundment in excess of that attributable to such rainfall event when it occurs.
NR 276.07(2)
(2) A process wastewater impoundment which is designed, constructed and operated so as to contain the precipitation from the 25 year, 24 hour rainfall event for the area in which such impoundment is located may discharge that volume of process wastewater which is equivalent to the volume of precipitation that falls within the impoundment in excess of that attributable to such rainfall event when it occurs.
NR 276.07(3)
(3) During any calendar month, there may be discharged from a process wastewater impoundment a volume of process wastewater equal to the difference between the precipitation for that month which falls within the impoundment and the evaporation from the pond water surface area for that month. Such discharges shall have a pH within the range of 6.0-9.0, daily average concentrations not to exceed 35, 10, and 25 mg/1 respectively of total phosphorus, fluoride, and suspended solids, and daily maximum concentrations not to exceed 70, 30, and 50 mg/1 respectively.
NR 276.07(4)
(4) The 10 year and 25 year, 24 hour rainfall events for the impoundment location shall be as set forth in

NR 276.10(4)
(4) For discharges from subcategories (1), (2) and (6) and human food grade calcium phosphate in subcategory (3), the 30-day average limitations for suspended solids and other parameters are set forth in table 1 in lbs/1000 lbs. or kg/1000 kg, of product. Daily maximum limitations are twice the 30-day average limitations, except for elemental phosphorus.
