Regulatory Approach for Shorter Chain-Length Telomer Alternatives In addition to requiring testing under TSCA §5(e), EPA also restricts uses pending development of an adequate understanding of the chemical's fate and effects and, consistent with the PFOA Stewardship Program, requires that the substitutes not be contaminated significantly with longer chain-length perfluorinated substances of concern. Regulatory ApproachĮPA's regulatory approach is intended to ensure that the new substances are safer alternatives. EPA reviews the new substances to identify whether the range of toxicity, fate and bioaccumulation issues that have caused past concerns with perfluorinated substances may be present, as well as any issues that may be raised by new chemistries, in order to ensure that the new chemical may not present an unreasonable risk to health or the environment. Through September 2015, hundreds of alternatives of various types have been received and reviewed by EPA. EPA's review of alternatives to PFASs has been ongoing since 2000. Regulatory Approach for Alternatives for Certain PFOA UsesĮPA is reviewing substitutes for perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS) and other long-chain per- and polyfluoroalkyl substances (PFASs) for new chemicals under EPA's New Chemicals Program (NCP).
