NR 240.04 History History: Cr. Register, June, 1976, No. 246, eff. 7-1-76; r. and recr. Register, August, 1983, No. 332, eff. 9-1-83.
NR 240.06 NR 240.06 Application of effluent limitations and standards.
NR 240.06(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 240.06(1)(a) (a) They may be modified in accordance with subch. IV of ch. NR 220,
NR 240.06(1)(b) (b) They may be superseded by more stringent limitations and standards necessary to achieve water quality standards or meet other legal requirements, or
NR 240.06(1)(c) (c) They may be supplemented or superseded by standards or prohibitions for toxic pollutants or by additional limitations for other pollutants required to achieve water quality.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 240.06(2) (2) The production basis for application of the limitations and standards set forth in this chapter shall be the daily average for a maximum month for the facility in each subcategory subject to the provisions of this chapter.
NR 240.06(3) (3) For a facility which manufactures one or more final products in only one of the subcategories of s. NR 240.02 using a process or processes involving the production of intermediate products in any other subcategories the total discharge limitation shall be the total of the amounts calculated from the BOD input in the final product subcategory and each of such other subcategories involved, except that,
NR 240.06(3)(a) (a) Such other subcategories shall not include receiving stations, subcategory (1), and
NR 240.06(3)(b) (b) If the facility is in subcategory (8) the total discharge limitation shall not include any amounts calculated for fluid mixes it prepares and shall be reduced by the amounts calculated for any fluid mixes it receives from other facilities.
NR 240.06(4) (4) For a facility which manufactures final products in more than one of the subcategories of s. NR 240.02 the total discharge limitation shall be the total of the amounts calculated in accordance with sub. (3) for each final product subcategory involved.
NR 240.06 Note Note: For example, a facility receives daily 300,000 pounds of 3.7% fat content whole milk, sells 100,000 pounds, makes cheese from 200,000 pounds, and produces dry whey, from the 180,000 pounds of fluid whey containing 12,480 pounds of solids produced in the cheese process. Dry whey production involves the intermediate production of condensed whey. The facility has final products in subcategory (1) (class B), (6) (class A), and (12) (class B) and an intermediate product in subcategory (11) (class B). Discharge limitations for the facility are calculated using s. NR 240.07 data to determine BOD input, and average effluent limitations in s. NR 240.10 to determine discharge limitations to be achieved by best practicable treatment, as shown in the table with data in pounds except that the BOD factor is in pounds for 100 pounds of raw materials and the effluent limitation in pounds per 1000 pounds of BOD input. - See PDF for table PDF
NR 240.06 Note (for column 3 divide column 1 by 100 and multiply by column 2; for columns 6 and 7 divide column 3 by 1000 and multiply by columns 4 and 5 respectively)
NR 240.06 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 240.07 NR 240.07 BOD of dairy product materials. The data in table 1 taken from the development document incorporated by reference in subch. IV of ch. NR 220, are generally accepted published values for the protein, fat, and carbohydrate content and BOD equivalent of common dairy products process materials and may be used to determine the BOD input of such materials in facilities subject to the provisions of this chapter. - See PDF for table PDF
NR 240.07 History History: Cr. Register, June, 1976, No. 246, eff. 7-1-76; correction made under s. 13.92 (4) (b) 7, Stats., Register April 2018 No. 748.
NR 240.10 NR 240.10 Effluent limitations, best practicable treatment. The following effluent limitations for all or specific subcategories when applied in accordance with s. NR 240.06 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 240.10(1) (1) The pH of all discharges shall be within the range of 6.0 to 9.0.
NR 240.10(2) (2) The 30-day average and daily maximum limitations for BOD5 and suspended solids are set forth in table 2 in lbs/1000lbs or kg/1000kg of BOD5 input. - See PDF for table PDF
NR 240.10 Note *These limitations are exclusive of barometric condenser discharges which shall be permitted with net concentration limits for BOD5 of 10 mg/l 30 day average and 15 mg/l daily maximum.
NR 240.10 History History: Cr. Register, June, 1976, No. 246, eff. 7-1-76; correction in (intro.) made under s. 13.92 (4) (b) 7, Stats., Register April 2018 No. 748.
NR 240.11 NR 240.11 Effluent limitations, best available treatment. The following effluent limitations for all or specific subcategories when applied in accordance with s. NR 240.06 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.
NR 240.11(1) (1) The pH of all discharges shall be within the range of 6.0 to 9.0.
NR 240.11(2) (2) The 30-day average and daily maximum limitations for BOD5 and suspended solids are set forth in table 3 in lbs/1000lbs or kg/1000kg of BOD5 input. - See PDF for table PDF
