The Environmental Protection Agency (EPA) is granting a petition submitted by OxyVinyls, LP (OxyVinyls) to exclude (or delist) a certain liquid waste generated by its Houston, TX Deer Park VCM Plant from the lists of hazardous wastes. This final rule responds to the petition submitted by OxyVinyls to delist K017, K019, and K020 Incinerator Offgas Treatment Scrubber Water generated from treating and neutralizing gasses generated in the firebox during the incineration process. 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 919,990 cubic yards per year of the Incinerator Offgas Treatment Scrubber Water. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in accordance with TPDES regulations.
