The U.S. EPA announced the agency is seeking public input on draft toxicity assessments for GenX chemicals and perfluorobutane sulfonic acid (PFBS), members of a larger group of per- and polyfluoroalkyl substances (PFAS). The draft assessments are part of EPA’s efforts to increase the amount of research and information that is publicly available on chemicals in the PFAS family.

EPA is continuing to work to develop a PFAS Management Plan that will outline the agency’s approach to addressing the PFAS challenge. The agency is working to release the plan as soon as possible. While the draft toxicity assessments are part of the management plan, the agency is releasing them now to ensure that communities across the country have access to this information as soon as it is available. Once final, states, tribes and communities can use the information the agency is providing to assess risks, which will help them develop risk management plans and protect their residents.

To develop these draft toxicity assessments, the agency relied on available science, including input from independent peer reviewers. The agency also engaged with federal and state partners throughout the development of the draft assessments. When issued, these toxicity assessments may be used by federal partners, states, tribes and local communities, along with specific exposure and other relevant information to determine, under the appropriate regulations and statutes, if and when it is necessary to take action to address potential risk associated with human exposures to these PFAS chemicals.

EPA will accept public comments on the GenX chemicals and PFBS draft toxicity assessments for 60 days after they are published in the Federal Register. EPA will then consider the public comments, revise the documents, and consider the need for additional review, as appropriate.
