(a) The following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section which may be discharged by a point source subject to the provisions of this subpart producing electrolytic manganese after application of the best practicable control technology currently available:
| Effluent characteristic | Effluent limitations | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | |
