On October 14, 2020, a coalition of non-governmental organizations (NGO) petitioned the U.S. Environmental Protection Agency (EPA) under Section 21 of the Toxic Substances Control Act (TSCA) to request that EPA require health and environmental effects testing on 54 per- and polyfluoroalkyl substances (PFAS). The petition seeks issuance of a rule or order under TSCA Section 4 compelling The Chemours Company (Chemours) to fund and carry out this testing under the direction of a panel of independent scientists. EPA acknowledged receipt of the petition, noting that TSCA Section 21 provides that the EPA Administrator shall either grant or deny a petition within 90 days (January 11, 2021, in this case) after the date of filing. If the Administrator grants the petition, the Administrator shall promptly commence an appropriate proceeding. If the Administrator denies the petition, the Administrator shall publish the reasons for such a denial in the Federal Register. EPA states that the petition is under review by the Office of Pollution Prevention and Toxics (OPPT). For more information on the petition, please read the full memorandum.
