TITLE: Long -Chain Perfluoroalkyl Carboxylate and Perfluoroalkyl Sulfonate Chemical Substances; 
Significant New Use Rule; Supplemental Proposal  
AGENCY: Environmental Protection Agency (EPA)  
ACTION: Supplemental notice of proposed rulemaking  
SUMMARY: EPA is supplementing a proposed significant new use rule  (SNUR) issued under 
section  5(a)(2) of the Toxic Substances Control Act (TSCA) for long -chain perfluoroalkyl 
carboxylate (LCPFAC) chemical substances to make inapplicable the exemption for persons who 
import a subset of LCPFAC chemical substances as part of surface coatings on articles. This subset 
of LCPFAC chemical substances also includes the salts and precursors of these perfluorinated 
carboxylates. This supplemental proposal would require importers to notify EPA at least 90 days 
before commencing the import of these chemical substances in certain articles for the significant 
new use described in this document. The required significant new use notification would initiate 
EPA's evaluation of the conditions of use associated with the intended significant new use. 
Manufacturing (including import) or processing for the significant new use would be prohibited 
from commencing until EPA has conducted a review of the notice, made an appropriate 
determination on the notice, and taken such actions as are required in association with that 
determination.  
Comments must be received on or before 17 April 2020.
