Proposal to Eliminate Use of de minimis Exemption for PFAS ReportingToday, EPA proposed a rule that would improve reporting of per- and polyfluoroalkyl substances (PFAS) to the TRI by, among other proposed changes, eliminating an exemption that allows facilities to avoid reporting information on PFAS when those chemicals are used in small, or de minimis, concentrations. Because PFAS are used at low concentrations in many products, this rule would ensure that covered industry sectors and federal facilities that make or use TRI-listed PFAS will no longer be able to rely on the de minimis exemption to avoid disclosing their PFAS releases and other waste management quantities for these chemicals. This proposal reflects the Biden-Harris Administration’s commitment to address the impacts of these forever chemicals, and advances EPA’s PFAS Strategic Roadmap to confront the human health and environmental risks of PFAS. |
