Members of the Science Advisory Committee on Chemicals

The Science Advisory Committee on Chemicals (SACC) provides independent advice on science and technical issues to assist EPA in implementing the Frank R. Lautenberg Chemical Safety for the 21st Century Act. Members of the SACC are appointed by the Administrator of EPA from candidates identified through a public call for nominations. Members serve staggered terms of appointment, generally of two to three years.

On March 22, 2018, the Administrator appointed eight additional members to serve on the SACC. These additional members will increase the balance of scientific perspectives and add experts with experience in labor, public interest, animal protection and chemical manufacturing and processing to the committee. These additional eight members will supplement the 18 expert members that were appointed on January 19, 2017.

EPA issued the original request for nominations in an August 26, 2016 Federal Register Notice. Public comments on SACC candidates were requested in December 9, 2016 and August 3, 2017 Federal Register Notices (read the more recent Federal Register Notice requesting public comments).
