Per- and Poly-Fluoroalkyl Chemical Substances Designated as Inactive on the TSCA Inventory; Significant New Use Rule; (9 page(s), in English)

Proposed rule - Under the Toxic Substances Control Act (TSCA), EPA is proposing a significant new use rule (SNUR) for those per- and poly-fluoroalkyl substances (PFAS) that have not been manufactured (including imported) or processed for many years and are consequently 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, such 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 SNUR would be 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 determination 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 use may present unreasonable risk to health or the environment and ensure that EPA can prevent future unsafe environmental releases of the PFAS subject to this SNUR.
