40 CFR 424.25: Standards of performance for new sources.

The following standards of performance establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a new source subject to the provisions of this subpart:

Effluent characteristic Effluent limitations

Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed—

Metric units (kg/Mwh)

TSS 0.032 0.016

Chromium total .001 .0005

Chromium VI .0001 .00005

Manganese total .011 .005

Cyanide total .0005 .0003

Phenols .0004 .0002

pH (1) (1)

English units (lb/Mwh)

TSS .071 .035

Chromium total .002 .0012

Chromium VI .0002 .0001

Manganese total .023 .012

Cyanide total .001 .0006

Phenols .0009 .0005

pH (1) (1)

1 Within the range 6.0 to 9.0.

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).
