NR 284.12(3)(b) (b) The daily maximum limitations for PCP, TCP and zinc are set forth in Table 5 in both lbs/ton and mg/l.

NR 284.12(3)(c) (c) The pH of all discharges shall be within the range of 5.0 to 9.0. Dischargers which continuously monitor pH shall be subject to the provisions set forth in s. NR 205.06.

NR 284.12(3)(d) (d) PCP and TCP limitations are only applicable to facilities where chlorophenolic-containing biocides are used. Permittees not using chlorophenolic-containing biocides shall certify to the department that they are not using these biocides.

NR 284.12(3)(e) (e) Zinc limitations are only applicable to groundwood facilities where zinc hydrosulfite is used as a bleaching agent. Groundwood facilities not using zinc hydrosulfite as a bleaching agent shall certify to the department that they are not using this bleaching compound.

NR 284.12(3)(f) (f) Noncontinuous dischargers shall not be subject to the daily maximum and 30-day average limitations for BOD5 and TSS, but shall be subject to annual average effluent limitations set forth in Table 4. Noncontinuous dischargers also shall be subject to concentration limitations in mg/l where provided.
