Environmental Protection Agency (EPA) is granting a petition submitted by Bayer Material Science in Baytown, Texas to exclude (or delist) the toluene diisocyanate (TDI) residues generated from its facility located in Baytown, Texas from the lists of hazardous wastes. This final rule responds to the petition submitted by Bayer Material Science to delist K027 TDI residues generated from the facility's distillation units. After careful analysis and use of the Delisting Risk Assessment Software (DRAS), EPA has concluded the petitioned waste is not hazardous waste. This exclusion applies to 9,780 cubic yards per year of the K027 residues. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when it is disposed in a Subtitle D Landfill.
