EPA Requests Nominations for Panel Members and Ad Hoc Reviewers for the Science Advisory Committee on Chemicals

Released December 31, 2025

U.S. Environmental Protection Agency (EPA) is soliciting nominations for scientific experts to be appointed to the Science Advisory Committee on Chemicals (SACC) panel. The agency is also soliciting nominations for as ad hoc reviewers for 2026 peer review meetings.

The SACC serves as a scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention. It provides independent scientific advice and recommendations to EPA on the scientific basis for risk assessments, methodologies and pollution prevention measures and approaches for chemicals regulated under the Toxic Substances Control Act (TSCA).  

SACC members serve staggered terms of appointment, generally of three years. Currently, there are ten SACC members with terms that will expire over the next year. Nominations should include candidates who have demonstrated high levels of competence, knowledge, and expertise in scientific/technical fields relevant to chemical safety and risk assessment. Additional details on the desired areas of expertise can be found in the Federal Register notice. Nominations of candidates to be considered for appointment to the SACC must be received on or before February 4, 2026.

For 2026, EPA is considering peer review for ten chemicals designated as high priority for risk evaluation under TSCA. EPA is intending to convene two SACC peer review meetings anticipated to occur in early and mid-2026. Nominees for ad hoc reviewers should be scientists who have sufficient professional qualifications, including training and expertise, to be capable of providing expert comments on the scientific issues for this review. Additional details on the desired areas of expertise can be found in the Federal Register notice. The final selection of the ad hoc peer reviewers will depend upon the scientific expertise needed to address the SACC peer review charge questions as well as to obtain a breadth and balance of different scientific viewpoints across the SACC and ad hoc peer reviewers. Nominations must be submitted on or before February 4, 2026.

For appointments to the SACC and for ad hoc reviewers, prospective candidates will be asked to submit confidential financial information. This confidential financial information must fully disclose, among other financial interests, the candidate's employment, stocks and bonds, and where applicable, sources of research support. EPA evaluates the candidates' financial disclosure forms to assess whether there are financial conflicts of interest, appearance of a loss of impartiality, or any prior involvement with the development of the documents under consideration (including previous scientific peer review) before the candidates are considered further.

Nominations for SACC appointments and ad hoc reviewers are due no later than 30 days from the date of publication in the Federal Register, via email to the SACC mailbox: SACC@epa.gov.
