EPA Comment Deadline: Significant New Use Rules on Certain Chemical Substances

Tuesday, November 12, 2019 - 5:00pm

The Environmental Protection Agency (EPA) is proposing and seeking comments on significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 31 chemical substances, including multiwalled carbon nanotubes, which were the subject of premanufacture notices (PMNs). Eight of these chemical substances are subject to TSCA Orders issued by EPA and the remaining 23 of these chemical substances received a “not likely to present an unreasonable risk” determination. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 31 chemical substances for an activity that is proposed as a significant new use to notify EPA at least 90 days before commencing that activity. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required by that determination.

Members of the public may submit comments online at Regulations.gov, or by mail. More information is available at this Federal Register notice.
