On July 27, 2020, the Environmental Protection Agency (“EPA”) finalized a significant new use rule (“SNUR”) for PFAS substances and other compounds under the Toxic Substances Control Act (“TSCA”), which was originally proposed in 2015. Although this is not the first SNUR for PFAS substances, it includes a new list of compounds, and may be important for your operations if those compounds are part of your business operations.
As described below, companies that manufacture, process, distribute, or import specific long-chain perfluoroalkyl carboxylate (LCPFAC) and perfluoroalkyl sulfonate chemical substances must notify EPA at least 90 days in advance of any manufacturing (including import), processing or distribution for a significant new use.
