What's Happening?
The Environmental Protection Agency (EPA) has announced the addition of sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI) under the Emergency Planning and Community Right-to-Know Act. This decision requires businesses in relevant
industries to track and report any use or release of PFHxS-Na that exceeds the threshold of 100 pounds. The reporting period commenced on January 1, 2026, with the first reports due by July 1, 2027. This move is part of the EPA's ongoing efforts to manage per- and polyfluoroalkyl substances (PFAS), following the 2020 National Defense Authorization Act mandate to add new PFAS chemicals to the TRI annually. The EPA had previously added seven PFAS chemicals in 2024 and nine in 2025. The inclusion of PFHxS-Na follows the finalization of its toxicity value in October 2025.
Why It's Important?
The inclusion of PFHxS-Na in the TRI is significant as it reflects the EPA's continued commitment to regulating PFAS chemicals, which are known for their persistence in the environment and potential health risks. This regulatory action impacts industries that utilize PFHxS-Na, requiring them to adhere to stricter reporting and monitoring standards. The decision underscores the broader environmental and public health strategy to mitigate the risks associated with PFAS exposure. Industries may face increased compliance costs and operational adjustments to meet these new requirements. The move also highlights the EPA's proactive stance in updating and enforcing environmental regulations to protect public health and the environment.
What's Next?
Industries affected by this new regulation will need to implement systems to accurately track and report PFHxS-Na usage and emissions. The EPA will likely continue to expand the list of PFAS chemicals under the TRI, necessitating ongoing adjustments by businesses to comply with evolving regulations. Stakeholders, including environmental advocacy groups and industry representatives, may engage in discussions or legal challenges regarding the implications of these regulations. The EPA's actions may also prompt further legislative or regulatory measures aimed at addressing PFAS contamination and its impacts.
