On June 22, 2020, U.S. EPA issued a final TSCA significant new use rule (SNUR) for long-chain perfluoroalkyl carboxylate (LCPFAC) and perfluoroalkyl sulfonate (PFAS) chemical substances. Specifically, the SNUR designates as a significant new use manufacturing (including importing) or processing of (i) an identified subset of LCPFAC chemical substances for any use that was not ongoing as of December 15, 2015 and (ii) for all other LCPFAC chemical substances for which there were no ongoing uses as of January 21, 2015.
The SNUR also makes inapplicable the exemption for persons who import LCPFAC chemical substances as part of the surface coating on articles (note that the SNUR narrows the scope of affected articles from all imported articles to only those articles that contain such a substance in a surface coating). The SNUR also makes inapplicable the exemption for persons who import PFAS chemical substances in carpets. Persons subject to this SNUR would be required to provide notification to U.S. EPA prior to manufacturing or importing these chemical substances which notification would trigger U.S. EPA’s TSCA review and evaluation of the intended use.
The final SNUR did drop two controversial provisions that would have provided a “de minimis” exemption below which notification would not be required and a “safe harbor” provision that would have allowed article importers to avoid enforcement action if they could demonstrate that their use was ongoing prior to the rule’s effective date.
In response to comments submitted on the proposed “safe harbor” provisions, U.S EPA noted that “[a] safe harbor approach undermines the regulatory process for what uses are allowed by permitting a manufacturer to claim a use was ongoing at the time the SNUR was issued” especially since manufacturers and/or importers were put on notice of the proposed SNUR five years ago.
With respect to the proposed “de minimis” threshold for articles before the notification requirements would kick in, U.S. EPA noted while it was not establishing a de minimis threshold in the final rule, U.S. EPA stated that it “will, however, continue to engage with interested stakeholders on this issue and continue to consider whether guidance for applying this standard may be appropriate in the future, whether as a general matter or, for instance, as applied to specific categories of substances or potential exposures.”
The SNUR will take effect 60 days after official publication in the Federal Register.
