EPA Withdraws SNUR for Single-Walled Carbon Nanotubes

The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on December 7, 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). See https://www.federalregister.gov/documents/2018/12/07/2018-26686/significant-new-use-rules-on-certain-chemical-substances-withdrawal As reported in our October 10, 2018, blog item, EPA issued the SNURs through a direct final rule on October 10, 2018. See https://nanotech.lawbc.com/2018/10/epa-publishes-snur-for-single-walled-carbon-nanotubes/ EPA states that it received adverse comments regarding the SNURs identified in the direct final rule, and is withdrawing them. On October 10, 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.
