National Law Review: “On Thursday, 29 June 2023, the US Environmental Protection Agency (EPA) announced a new framework (Framework) that will impact manufacturers across the country. The Framework lays out a new process for reviewing and assessing the potential environmental risks posed by new and new uses of per- and poly-fluoroalkyl substances (PFAS). This PFAS Framework establishes more stringent pre-market screening procedures for certain PFAS chemicals that may be harmful to human health or the environment. Under the Framework, the EPA will review and take appropriate action for new PFAS or significant new uses of existing PFAS through pre-manufacture notices (PMNs) and significant new use notices (SNUNs) through the EPA’s authority under the Toxic Substances Control Act (TSCA).”
