OMB Finishes Review of Proposed SNUR on LCPFAC and PFAS Chemical Substances

Lynn L. Bergeson Carla N. Hutton

As reported in our October 1, 2019, blog item, on September 25, 2019, the U.S. Environmental Protection Agency (EPA) submitted a proposed significant new use rule (SNUR) on long-chain perfluoroalkyl carboxylate (LCPFAC) and perfluoroalkyl sulfonate (PFAS) chemical substances to the Office of Management and Budget (OMB) for review.  According to OMB’s website, OMB completed its review on February 14, 2020.  EPA has not yet publicly released the proposed rule.
According to the item on the rulemaking in EPA’s fall 2019 Unified Agenda, EPA is developing a supplemental proposal to its 2015 proposed LCPFAC SNUR amendments.  EPA states that the supplemental proposal would make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of certain articles.  According to EPA, this supplemental proposal is necessary to be responsive to the article consideration provision in Section 5(a)(5) of the Toxic Substances Control Act (TSCA) that was added with the 2016 amendments to TSCA.  Under the provision, articles can be subject to notification requirements as a significant new use provided that EPA makes an affirmative finding in a rule that the reasonable potential for exposure to a chemical from an article or category of articles justifies notification.  Insofar as this new provision has not been used previously for chemical substances with a history of prior import in articles, EPA’s approach to and its arguments in making this required affirmative finding will be important for all stakeholders to consider carefully.
