The Color Pigments Manufacturers Association, Inc. (CPMA) is currently evaluating a new rule proposed by the U.S. Environmental Protection Agency (EPA) concerning the identification and listing of hazardous production waste in the manufacture of certain organic pigments and dyes. This latest proposal differs significantly from and supercedes two proposals concerning the color pigments industry that had been issued in 1994 and 1999 by the EPA to list hazardous waste streams from the production of certain dyes, pigments and FD&C colorants as hazardous waste under the Resource Conservation and Recovery Act (RCRA). Process related wastewater is not proposed for listing as hazardous, although the EPA in the earlier proposed rules had proposed listing wastewaters from the production of pigments and dyes. This latest proposal applies only to process related solid wastes, such as wastewater treatment sludge, air pollution control dusts and filter aids (called in the rule "non-wastewaters").
