Frequent Questions

Has EPA amended or changed the Hazardous Waste Combustion NESHAP since it was originally promulgated in 1999?

Yes. Since 1999 we have issued several technical corrections and amendments to the Phase 1 Hazardous Waste Combustion NESHAP to improve its implementation. We have also revised specific sections in response to the mandates issued by the Court of Appeals for the District of Columbia Circuit. Most notably, we promulgated negotiated interim emission standards that temporarily replace the 1999-promulgated standards that were challenged, and we extended the compliance date by one year.
For more specific information regarding changes to the Phase 1 NESHAP since its original publication in 1999, see the Corrections and Amendments to the Phase 1 Hazardous Waste Combustion NESHAP Fact Sheet (PDF, 322 KB) located in the Fact Sheet module of the Toolkit.
