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)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).

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)
