(b) Noncontinuous dischargers shall not be subject to the daily maximum and 30-day average limitations for BOD 5, TSS and zinc, but shall be subject to annual average effluent limitations set forth in Table 2.

(c) The annual average limitations for BOD 5, TSS and zinc are set forth in Table 2 in lbs/ton of product.

(d) The limitations for wet barking operations, log washing or chip washing, and log flumes or log ponds set forth in Table 1 are in addition to the limitations for the specific base subcategory set forth in that table.

(e) Dischargers which continuously monitor pH shall be subject to the provisions set forth in s. NR 205.06
