On June 15, 2021, the U.S. Environmental Protection Agency (EPA) appointed nine new members to serve on the Toxic Substances Control Act (TSCA) Science Advisory Committee on Chemicals (SACC). Additionally, EPA appointed a new Chair and reappointed seven existing members. In EPA’s July 13, 2021, announcement, EPA notes that members of the TSCA SACC serve staggered terms of appointment, generally of three years. They possess expertise in scientific and technical fields relevant to chemical risk assessment and pollution prevention, including human health and ecological risk assessment and chemical exposure to susceptible life stages and subpopulations. EPA states that in addition to scientific expertise, members also have backgrounds and experiences that will contribute to the diversity of scientific viewpoints, including professional experiences in government, public health, industry, and other groups. According to EPA, TSCA SACC serves as a primary scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide 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 TSCA.
