Final Emission Standards For Sewage Sludge Incinerators

EPA is finalizing emission standards for sewage sludge incinerators. It is estimated that the final rules will affect more than 200 sewage sludge incinerators across the country, however, EPA expects that many facilities are already in compliance. These standards will limit emissions of mercury, lead, cadmium, and hydrogen chloride.

EPA has also identified which non-hazardous secondary materials are considered solid waste when burned in combustion units. This distinction determines which Clean Air Act standard is applied when the material is burned. The non-hazardous secondary materials that can be burned as non-waste fuel include scrap tires managed under established tire collection programs. This step simplifies the rules and provides additional clarity and direction for facilities. To determine that materials are non-hazardous secondary materials when burned, materials must not have been discarded and must be legitimately used as a fuel.
