On April 5, 2019, the U.S. Environmental Protection Agency (EPA) issued a final rule that will establish final significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for 13 chemical substances that are the subject of premanufacture notices (PMN). 84 Fed. Reg. 13531. The final rule is significant because the 13 chemical substances are not also subject to consent orders. During the review, EPA identified certain reasonably foreseen conditions of use that it designated as significant new uses in the final SNURs. The final SNURs effectively prohibit the designated new use unless a person submits a notice to EPA, EPA makes a determination, and it takes any necessary action to mitigate any identified potential risk. The final rule will become effective on June 4, 2019. Please see our full memorandum for more information on this final rule.
