Lynn L. Bergeson, “Proposed PFAS and LCPFAC SNURs,” Pollution Engineering, November 2012.

On August 15, 2012, EPA issued proposed amendments to the significant new use rule (SNUR) for perfluoroalkyl sulfonate (PFAS) chemical substances to add seven PFAS chemical substances that have completed the new chemical review process under the Toxic Substances Control Act (TSCA). EPA has not yet commenced production or import, and to designate (for all listed PFAS chemical substances) “processing” as a significant new use. The agency is also proposing a SNUR for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances with lengths equal to or greater than seven carbons that would designate manufacturing, importing, or processing for use as part of carpets or for treating carpets.
