2060-AP90 201104 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Air and Radiation AR 2000 Environmental Protection Agency EPA NSPS/Emission Guidelines (EG) for Sewage Sludge Incinerators Under section 129 of the Clean Air Act (CAA), EPA is required to adopt and implement maximum achievable control technology (MACT) standards for both new and existing Sewage Sludge Incineration units (SSI). Regulations for Other Solid Waste Incinerators (OSWI) were promulgated on December 15, 2005. However, at that time, EPA did not issue standards or guidelines for SSI units and several other incinerator categories. In 2007, the D.C. Circuit Court of Appeals issued a decision vacating EPA's definition of "solid waste incineration unit," holding that "any facility that combusts any commercial or industrial solid waste material at all" is a commercial or industrial solid waste incineration unit. Based on this decision, in this rulemaking, EPA has proposed a new definition of non-hazardous solid waste. The new NHSW definition proposes that Sewage Sludge is a solid waste and therefore must be regulated under section 129.
