Frequent Questions

Did the 1999 Hazardous Waste Combustion NESHAP set emission standards for all hazardous waste combustors?

No. The 1999 Hazardous Waste Combustion NESHAP set emission standards for a subset of the hazardous waste combustion universe. This is because we chose to promulgate the NESHAP in two phases. The first phase, or Phase 1, addressed hazardous waste burning incinerators, cement kilns, and lightweight aggregate kilns. The facilities that comprise these three categories burn over 80 percent of the total amount of hazardous waste combusted each year. We first promulgated the Phase 1 standards on September 30, 1999 (64 FR 52828). We later replaced them on February 13, 2002, with negotiated interim standards in response to a mandate issued by the Court of Appeals for the District of Columbia Circuit (67 FR 6792).
