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).
