Section NR 254.013 - Effluent limitations representing the degree of effluent reduction attainable by the application of the best available technology economically achievable(1) Except as provided in 40 CFR 125.30 to 125.32, any existing source subject to this subchapter shall achieve the effluent limitations in sub. (2), (3), or (4) representing the degree of effluent reduction attainable by the application of BAT.(2) IRON AND STEEL BYPRODUCT COKEMAKING. (a) The following BAT effluent limitations apply: Table 3
| BAT 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 |
Ammonia-N | 0.0543 | 0.0160 |

(b) Increased loadings, not to exceed 16% 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 39% 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. (d) The following BAT effluent limitations shall be applicable to plants with physical chemical treatment systems: Table 4
