NESHAPS: Final Standards for Hazardous Air Pollutants for Hazardous Waste Combustors; Final Rule-Interpretive Clarification; Technical Correction

On September 30, 1999 (64 FR 52828), EPA issued a final rule promulgating revised standards for hazardous waste incinerators, hazardous waste burning cement kilns, and hazardous waste burning lightweight aggregate kilns. These standards were promulgated under joint authority of the Clean Air Act (CAA) and Resource Conservation and Recovery Act (RCRA). Sources subject to these standards have raised questions regarding the applicability of new source versus existing source standards for hazardous waste incinerators. In part one of today's rule, we clarify the original intent of our rule on these issues. In part two of today's rule, we make three technical corrections.
