On March 21, 2011, a final rule title “Identification of Non-Hazardous Secondary Material That Are Solid Waste” was published in the Federal Register. See, 76 Fed. Reg. 15456. The final rule does not as much identify that which is a solid waste as it identifies materials that are not solid waste. The effect of the rule is to determine whether combustion units should be regulated under Section 129 or Section 112 of the Clean Air Act (CAA) – solid waste is regulated under Section129 and non-solid waste under Section112. See, 76 Fed. Reg. 15610.
Under current regulations, certain materials (spent, sludges, by-products, specific chemical products and scrap) are solid waste when burned for energy recovery. See, 40 C.F.R. §261.2(c)(2). Materials are not solid waste when recycled through use or reuse as ingredients, as substitute products, or returned to the original process. See, 40 C.F.R. §261(e). The preamble of the final rule expands recycling by indicating that it includes burning for energy recovery. See, 76 Fed. Reg. 15468-69.Continue Reading EPA Clarifies Solid Waste Materials
