What was the scope of the October 2005 Final Hazardous Waste Combustor MACT Rule?

The hazardous waste combustor final rule was promulgated on October 12, 2005, and established national emission standards for hazardous air pollutants for sources that burn hazardous waste: commercial and onsite incinerators, cement kilns, lightweight aggregate kilns, boilers, and hydrochloric acid production furnaces. These standards were promulgated pursuant to Section 112 (d) of the Clean Air Act, which requires EPA to issue technology-based standards reflecting the performance of the Maximum Achievable Control Technology (MACT).
