The United States Environmental Protection Agency (EPA) published a Federal Register notice on 7 December 2018, withdrawing significant new use rules (SNUR) promulgated under the Toxic Substances Control Act (TSCA) for 28 chemical substances, including single-walled carbon nanotubes, that were the subject of premanufacture notices (PMN). As reported in our 10 October 2018, blog item, EPA issued the SNURs through a direct final rule on 10 October 2018. EPA states that it received adverse comments regarding the SNURs identified in the direct final rule, and is withdrawing them. On 10 October 2018, EPA also issued proposed SNURs covering these 28 chemical substances. EPA states that it will address all adverse public comments in a subsequent final rule, based on the proposed SNURs.
