EPA Accepting Public Comments on Candidates to Be Ad Hoc Reviewers for Draft Documents Related to Cumulative Risk Assessment under TSCA
The U.S. Environmental Protection Agency (EPA) announced on February 13, 2023, that it will accept public comments on candidates under consideration for selection as ad hoc reviewers to assist the Science Advisory Committee on Chemicals (SACC) with peer review of two draft documents related to cumulative risk assessment under the Toxic Substances Control Act (TSCA). Biographies of these candidates are available on regulations.gov. If selected, candidates will serve as peer reviewers for two documents, which will be reviewed by the SACC at a public virtual meeting May 8-11, 2023. Comments on the candidates are due February 25, 2023.
EPA states that it plans to release the following documents for public comment in late February 2023:
- Draft Proposed Principles of Cumulative Risk Assessment under the Toxic Substances Control Act: According to EPA, this document will describe the fundamental principles of cumulative risk assessment of chemicals and how they may be applied within the regulatory requirements of TSCA to ensure TSCA risk evaluations are based on the best available science and are protective of human health; and
- Draft Proposed Approach for Cumulative Risk Assessment of High-Priority Phthalates and a Manufacturer Requested Phthalate under the Toxic Substances Control Act: EPA states that this document will describe its proposed approach for evaluating a subset of high-priority and manufacturer-requested phthalates for cumulative risk to human health under TSCA based on the principles of cumulative risk assessment described in EPA’s draft principles document referenced above.
The SACC serves as a scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP). It provides independent scientific advice and recommendations to EPA on the scientific basis for risk assessments, methodologies, pollution prevention measures, and approaches for chemicals regulated under TSCA.
