| Effluent characteristic | Effluent limitations | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | |
| Metric units (kg/Mwh) | ||
| Chromium total | 0.001 | 0.0005 |
| Chromium VI | .0001 | .00005 |
| Manganese total | .011 | .005 |
| Cyanide total | .0005 | .0003 |
| Phenols | .0004 | .0002 |
| English units (lb/Mwh) | ||
| Chromium total | .002 | .0012 |
| Chromium VI | .0002 | .0001 |
| Manganese total | .023 | .012 |
| Cyanide total | .001 | .0006 |
| Phenols | .0009 | .0005 |
Provided, however, That for nonelectric furnace smelting processes, the units of effluent limitations set forth in this section shall be read as “kg/kkg of product” rather than “kg/Mwh,” and the limitations (except for pH) shall be 3.3 times those listed in the table in this section (or, for English units, “lb/ton of product” rather than “lb/Mwh,” and the limitations (except for pH) shall be three times those listed in the table).
