Standards for the Management and Use of Slag Residues Derived From HTMR Treatment of K061, K062, and F006 Wastes

摘要

The Environmental Protection Agency (EPA or the Agency) is proposing to allow materials resulting from the treatment of certain hazardous wastes to be used as a product in road construction and as an anti-skid/deicing material on road surfaces. These materials are residues (``slags'') generated from the treatment of pollution control dusts resulting from scrap metal recycling (electric arc furnace dust). The Agency evaluated the potential risks that might arise from the use of these ``slags'', and determined that these uses do not present a significant risk. This action would reclassify these treated materials as nonhazardous and allow these uses, but only if the toxic metals in the waste are reduced to safe levels by treatment. The Agency is proposing this action to clarify two seemingly inconsistent parts of the regulations governing residual materials generated from the treatment of hazardous wastes. This rule clarifies what uses of the treatment residues are allowed, and specifies what conditions must be met for these materials to be used in this manner. Furthermore, this action partially fulfills a settlement agreement entered into by the Agency with the Natural Resources Defe
