Emission Guidelines: Municipal Waste Combustors

The EPA is proposing new subpart Cb ``emission guidelines'' to be used by States in developing State regulations to control emissions from existing municipal waste combustors (MWC's). Today's proposed guidelines would apply to MWC's for which construction, modification, or reconstruction began on or before September 20, 1994. Today's proposal would implement sections 111 and 129 of the Clean Air Act (Act). The proposed guidelines would apply to existing MWC units at facilities with capacities to combust greater than 35 megagrams per day (Mg/day; a megagram is a metric ton, and one megagram is equal to 2,204 pounds or about 1.1 short tons) of municipal solid waste (MSW) and would require sources to achieve emission levels reflecting the maximum degree of reduction in emissions of air pollutants that the Administrator determines is achievable, taking into consideration the costs, non-air-quality health and environmental impacts, and energy impacts. The proposed guidelines would establish emission limits for MWC acid gases (sulfur dioxide (SO 2) and hydrogen chloride (HCl)), MWC metals (particulate matter (PM), opacity, cadmium (Cd), lead (Pb), and mercury (Hg)), MWC organics (dioxins
