On October 13th, 2022, Earthjustice on behalf of environmental organizations and community advocates petitioned the U.S. Environmental Protection Agency (EPA) to revoke the approval of approximately 600 per- and polyfluoroalkyl substances (PFAS) which were previously exempted under the Toxic Substances Control Act (TSCA). According to Earthjustice these PFAs possess a high threat to humans and the environment and are n not within the standard and need revocation of the same.

The following action is required by EPA:

1. For the existing LVEs (Low Volume Exemptions) and LoREXs (Low Release and Low Exposure Exemptions) granted, EPA must make a preliminary determination that these PFAs do not meet the TSCA standard.

2. EPA to notify their manufacturers.

3. The PFAs must be re-analysed again to determine if they fall short of the standards.

5. EPA should immediately stop permitting the use of the LVE, LoREX, and polymer exemption for any new PFAS.
