NR 237.03(2) (2) “Existing source” means any point source, except for a new source as defined in sub. (7), from which pollutants are or may be discharged either into waters of the state or into a publicly owned treatment works.

NR 237.03(3) (3) “Extraction operation” means an operation which produces either biological or natural extraction products, such as blood fractions, vaccines, serums, animal bile derivatives, endocrine products, or medicinal products, such as alkaloids, isolated from botanical drugs and herbs.

NR 237.03(4) (4) “Long term daily average raw waste load” means the average daily mass of a pollutant discharged to the wastewater treatment system over the 12 consecutive month period with the greatest production within the most recent 36 months.

NR 237.03(5) (5) “Maximum 30-day average” means the maximum average of daily values for 30 consecutive days.

NR 237.03(6) (6) “Mixing, compounding, and formulation operation” means an operation which blends, mixes, compounds, or formulates pharmaceutical ingredients into preparations, such as ampules, tablets, capsules, vials, ointments, medicinal powders, solutions, and suspensions, for either human or veterinary use.

NR 237.03(7) (7) “New source” means any point source for which construction commenced after November 26, 1982, and from which pollutants are or may be discharged directly to the waters of the state or to a publicly owned treatment works.

NR 237.03 History History: Cr. Register, May, 1990, No. 413, eff. 6-1-90.

NR 237.04 NR 237.04 Monitoring requirement. Unless otherwise noted, self-monitoring shall be conducted at the final effluent discharge point.

NR 237.04 History History: Cr. Register, May, 1990, No. 413, eff. 6-1-90.

NR 237.05 NR 237.05 Cyanide.

NR 237.05(1) (1) Certificate. Permittees not using or generating cyanide must certify to the control authority that cyanide is neither used nor generated.

NR 237.05(2) (2) Direct dischargers. The following requirements are applicable to any facility which is a direct discharger and which uses or generates cyanide:

NR 237.05(2)(a) (a) If all waste streams containing cyanide are diverted to a cyanide destruction unit and if the effluent from the cyanide destruction unit is discharged to a biological treatment system, self monitoring shall be conducted after cyanide treatment and before dilution with other streams, except as provided in par. (b).

NR 237.05(2)(b) (b) Self monitoring may be conducted at the final effluent discharge point if 3 adjustments are made:

NR 237.05(2)(b)1. 1. The daily maximum cyanide limitation is multiplied by 0.18;

NR 237.05(2)(b)2. 2. The 30-day maximum cyanide limitation is multiplied by 0.35; and

NR 237.05(2)(b)3. 3. The daily and 30-day maximum cyanide limitations are further adjusted according to the ratio of the flow of the waste streams containing cyanide to the total process wastewater discharge flow.

NR 237.05(2)(c) (c) If all waste streams containing cyanide are not treated in a cyanide destruction unit or if the effluent from the cyanide destruction unit is not discharged to a biological treatment system, self monitoring shall be conducted at the final effluent discharge point as provided in par. (b).

NR 237.05(3) (3) Discharges to a publicly owned treatment works. The following requirements are applicable to any facility which discharges to a POTW and which uses or generates cyanide:

NR 237.05(3)(a) (a) If all waste streams containing cyanide are diverted to a cyanide destruction unit, self monitoring shall be conducted after cyanide treatment and before dilution with other streams, except as provided in par. (b).

NR 237.05(3)(b) (b) Self monitoring may be conducted at the final effluent discharge point if the daily and 30-day maximum cyanide standards are adjusted according to the ratio of the flow of the waste streams containing cyanide to the total process wastewater discharge flow.

NR 237.05(3)(c) (c) If all waste streams containing cyanide are not treated, self monitoring shall be conducted at the final effluent discharge point as provided in par. (b).

NR 237.05 History History: Cr. Register, May, 1990, No. 413, eff. 6-1-90.

NR 237.06 NR 237.06 Dilution. Dilution to meet the standards set forth in this chapter may not be practiced.

NR 237.06 History History: Cr. Register, May, 1990, No. 413, eff. 6-1-90.

NR 237.07(1) (1) Any existing source subject to this chapter which discharges to waters of the state shall achieve:

NR 237.07(1)(a) (a) The effluent limitations representing BPT by July 1, 1977; and

NR 237.07(1)(b) (b) The effluent limitations representing BAT by July 1, 1984.
