Section NR 295.11 - Effluent limitations, best available treatment

The following effluent limitations for all or specific subcategories establish the quantity or quality of pollutants or pollutant properties which may be discharged by a facility subject to the provisions of this chapter after application to process wastes of the best available technology economically achievable.

(1) For facilities in the beet sugar subcategory processing more than 2,300 tons (2,090 kkg) daily of sliced beets and located where the soil filtration rate, naturally or by deliberate design within the boundaries of waste water treatment or retention facilities, in available areas is more than 1/16-inch (0.159 cm) per day there shall be no discharge of process wastes to surface waters.

(2) For facilities in the sugar beet subcategory processing a smaller quantity of sliced beets than is set forth in sub. (1), and/or located where the soil filtration rate is less than set forth therein, the discharges shall be limited as set forth in subs. (3) and (4).

(3) For facilities subject to the provisions of this chapter other than sub. (1) the pH limitations and the 30-day average and daily maximum limitations for BOD5 and suspended solids are set forth in table 2. Limitations are set forth for 2 types of discharges from facilities described in sub. (2);

(a) Discharges from barometric condensing operations only, and

(b) Discharges from barometric condensing operations combined with discharges of other process wastes.

(4) In addition to the limitations of sub. (3) discharges from facilities described in sub. (2) shall be limited as set forth in s. NR 295.10(3) (a) and (b).
