Polytetrafluoroethylene; Revocation of the Tolerance Exemption When Used as an Inert Ingredient in Pesticide Products. Proposed Rule

The Environmental Protection Agency (EPA or Agency) is
proposing to revoke the tolerance exemption for residues of
polytetrafluoroethylene (CAS No. 9002-84-0) under the Federal Food,
Drug, and Cosmetic Act (FFDCA) when used as an inert ingredient in
pesticide formulations. EPA is proposing to revoke this tolerance
exemption because polytetrafluoroethylene, which has been identified as
a per- and polyfluoroalkyl substance (PFAS), is no longer used in any
registered pesticide product.
