EPA is issuing a final rule to update the Toxics Release Inventory (TRI) chemical list to identify nine additional PFAS subject to reporting requirements. TRI data are reported to EPA annually by facilities in certain industry sectors, including federal facilities, that manufacture, process, or otherwise use TRI-listed chemicals above certain quantities. The data collected help to support informed decision-making by companies, government agencies, non-governmental organizations, and the public. The data collected also help inform EPA's efforts to better understand the listed substances. As part of EPA's PFAS Strategic Roadmap, the Agency also proposed a rule in December 2022 to enhance PFAS reporting to TRI by 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, that 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
