NR 295.06 NR 295.06 Application of effluent limitations and standards.

NR 295.06(1) (1) The effluent limitations and standards set forth in this chapter shall be used in accordance with this section to establish the quantity or quality of pollutants or pollutant properties which may be discharged by a point source subject to the provisions of this chapter, except as;

NR 295.06(1)(a) (a) They may be modified in accordance with subch. IV of ch. NR 220,

NR 295.06(1)(b) (b) They may be superseded by more stringent limitations and standards necessary to achieve water quality standards or meet other legal requirements, or

NR 295.06(1)(c) (c) They may be supplemented or superseded by standards or prohibitions for toxic pollutants or by additional limitations for other pollutants required to achieve water quality.

NR 295.06(2) (2) The production basis for application of the limitations and standards set forth in this chapter shall be the daily average of a maximum month in each subcategory subject to the provisions of this chapter.

NR 295.06 History History: Cr. Register, June, 1976, No. 246, eff. 7-1-76; correction in (1) (a) made under s. 13.92 (4) (b) 7, Stats., Register April 2018 No. 748.

NR 295.10 NR 295.10 Effluent limitations, best practicable treatment. The following effluent limitations for all or specific subcategories establish, except as provided in subch. IV of ch. NR 220, 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 practicable control technology currently available.

NR 295.10(1) (1) The pH limitations and the 30-day average and daily maximum limitations for BOD5 and suspended solids are set forth in table 1 for 2 types of discharges from each subcategory;

NR 295.10(1)(a) (a) Discharges from barometric condensing operations only, and

NR 295.10(1)(b) (b) Discharges from barometric condensing operations combined with discharges of other process wastes.

NR 295.10(2) (2) The limitations for BOD5 and suspended solids in table 1 are in lbs/1000 lbs. or kg/1000 kg. of product for the beet sugar subcategory and of melt for both cane sugar subcategories, and shall be on the net basis for either of the cane sugar subcategories where the type of discharges described in sub. (1) (b) are mixed and cannot be separated for measurement.

NR 295.10(3) (3) In addition to the limitations of sub. (2) , discharges from the beet sugar subcategory shall also be limited;

NR 295.10(3)(a) (a) For discharges described in sub. (1) (a) to the temperature acceptable for recirculation to the heat source or in any event not to exceed 90°F (32°C), and
