Description:  Under the Toxic Substances Control Act ( TSCA ), EPA is finalizing a significant new use 
rule (SNUR) for 329 per- and poly -fluoroalkyl substances (PFAS)  that are designated as inactive on 
the TSCA Chemical Substance Inventory . PFAS are a group of chemicals that have been used in 
industry and consumer products since the 1940s because of their useful properties, suc h as water 
and stain resistance. Many PFAS break down very slowly and can build up in people, animals, and 
the environment over time. Exposure at certain levels to specific PFAS can adversely impact human

  health and other living things. Persons subject to the final SNUR are required to notify EPA at least 
90 days before commencing any manufacture (including import) or processing of the chemical 
substance for a significant new use. Once EPA receives a notification, EPA must review and make an 
affirmative det ermination on the notification, and take such action as is required by any such 
determination before the manufacture (including import) or processing for the significant new use 
can commence. Such a review will assess whether the new use may present unreas onable risk to 
health or the environment and ensure that EPA takes appropriate action as required to protect health 
or the environment.
