Abstract |
This manual is intended to provide guidance to federal and state NPDES permit and pretreatment staffs in determining appropriate limitations for the discharge of selected toxic pollutants in the wastewater from industrial facilities where applicable Effluent Guidelines regulations are not available. From his extensive knowledge and comprehensive review of the treatment technology available to industry, the author has determined, in his best professional judgement, the final effluent concentrations that can be achieved using his estimate of best available technology (BAT) for the following toxic pollutants: arsenic, barium, cadmium, hexavalent chromium, total chromium, copper, cyanide, fluoride, iron, mercury, nickel, silver, and zinc. It is concluded that, aside from a few extraordinary situations involving unusual chemical interferences, the treatability levels provided in the manual should be applicable, independent of industrial category. |
