| BCT Effluent Limitations |
Maximum for any 1 day | Average of daily values for 30 consecutive days |
Pollutant or pollutant property | kg/kkg (pounds per 1,000 pounds) of product |
TSS | 0.253 | 0.131 |
O&G | 0.0327 | 0.0109 |

(1) Within the range of 6.0 to 9.0
(b) Increased loadings, not to exceed 11% above the limitations in par. (a), are allowed for plants which have wet desulfurization systems but only to the extent that such systems generate an increased effluent volume. (c) Increased loadings, not to exceed 27% above the limitations in par. (a), are allowed for plants which include indirect ammonia recovery systems but only to the extent that such systems generate an increased effluent volume. (3) MERCHANT BYPRODUCT COKEMAKING.
