EPA is proposing to add per- and polyfluoroalkyl substances (PFAS) subject to reporting under the EPCRA and the PPA pursuant to the NDAA to the list of Lower Thresholds for Chemicals of Special Concern (chemicals of special concern). These PFAS already have a lower reporting threshold of 100 pounds. The addition of these PFAS to the list of chemicals of special concern will cause such PFAS to be subject to the same reporting requirements as other chemicals of special concern (i.e., it would eliminate the use of the de minimis exemption and the option to use Form A and would limit the use of range reporting for PFAS). Removing the availability of these burden-reduction reporting options will result in a more complete picture of the releases and waste management quantities for these PFAS. In addition, EPA is proposing to remove the availability of the de minimis exemption for purposes of the Supplier Notification Requirements for all chemicals on the list of chemicals of special concern. This change will help ensure that purchasers of mixtures and trade name products containing such chemicals are informed of their presence in mixtures and products they purchase.
