The Pollution Prevention Act (PPA) and Emergency Planning and Community Right-to-Know Act (EPCRA) both will require reporting of per- and polyfluoroalkyl substances (PFAS), according a recent proposal by the U.S. Environmental Protection Agency (EPA). The reporting threshold for certain PFAS is already lower, at 100 pounds. These PFAS will be subject to the same reporting requirements as other chemicals of special concern as a result of their inclusion on the list of chemicals of special concern. Additionally, EPA is recommending that all substances on the list of chemicals of particular concern be excluded from the Supplier Notification Requirements' de minimis exemption. This modification will make it possible to ensure that consumers who buy mixes and brand-name items containing such compounds are aware of their inclusion in the mixtures and products they buy. By February 03, 2023, public comments on this proposed rule are requested.
