EPA published preliminary Toxics Release Inventory (TRI) data about chemical releases, waste management and pollution prevention activities that took place during 2023 at more than 20,000 federal and industrial facilities across the country. For 2023, 21 chemicals were added to the TRI list, and facilities were required to report on these if the reporting thresholds for each were met. The chemicals included nine per- and polyfluoroalkyl substances (PFAS) added to the TRI chemical list per the requirements of the 2020 National Defense Authorization Act (NDAA).
