(b) The following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section, resulting from the use of wet barking operations, which may be discharged by a point source subject to the provisions of this subpart. These limitations are in addition to the limitations set forth in paragraph (a) of this section and shall be calculated using the proportion of the mill's total production due to use of logs which are subject to such operations:

(d) The following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section, resulting from the use of log flumes or log ponds, which may be discharged by a point source subject to the provisions of this subpart. These limitations are in addition to the limitations set forth in paragraph (a) of this section and shall be calculated using the proportion of the mill's total production due to use of logs which are subject to such operations:
| Pollutant or pollutant property | Kg/kkg (or pounds per 1,000 lb) of product | ||
|---|---|---|---|
| Continuous dischargers | Non-continuous dischargers (annual average) | ||
| Maximum for any 1 day | Average of daily values for 30 consecutive days | ||
| BOD5 | 0.35 | 0.2 | 0.1 |
| TSS | 1.7 | 0.9 | 0.5 |
| pH | ( 1) | ( 1) | ( 1) |
