Sec. 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:

\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).
