The U.S. Environmental Protection Agency (EPA) has released a pre-publication version of its direct final rule signed on April 5, 2017, which states that EPA will be promulgating significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for 37 chemical substances which were the subject of premanufacture notices (PMN). This action will require persons who intend to manufacture or process any of these 37 chemical substances for an activity that is designated as a significant new use (SNU) by this rule to notify EPA at least 90 days before commencing that activity. This final rule will become effective 60 days after publication in the Federal Register. We note that all of these substances were reviewed under old TSCA, prior to June 22, 2016.
