NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Waste Combustors; Extension of Comment Period

Riepilogo

EPA is announcing that the comment period to the notice entitled "NESHAP: National Emission Standards for Hazardous Air Pollutants: Standards for Hazardous Waste Combustors; Solicitation of Comment on Legal Analysis," published on September 27, 2007 (72 FR 54875), is being extended until November 27, 2007. In that notice, EPA discusses the standards for hazardous waste combustors that were promulgated on October 12, 2005 (70 FR 59402), and specifically identifies which standards EPA believes are consistent with the Clean Air Act and case law, and which standards are not and need to be reexamined through a subsequent rulemaking. This analysis of the standards is being done in response to several opinions issued by the United States Court of Appeals for the District of Columbia Circuit that call into question the legality of some of the standards for hazardous waste combustors.
