What: On January 5, 2026, the U.S. Environmental Protection Agency (EPA) announced that it is seeking nominations of scientific and technical experts for service as ad hoc peer reviewers assisting the Science Advisory Committee on Chemicals (SACC).
Why: Individuals who are nominated would assist EPA as it considers ten Toxic Substances Control Act (TSCA)-designated High-Priority chemicals. The EPA is conducting these chemical review evaluations to help inform whether the chemical substances present unreasonable risks to human health and/or the environment under the conditions of use, as required by TSCA.
The EPA expects to convene SACC peer review meetings in both early and mid-2026.
Chemicals being considered for review in early 2026 include:
- 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta [g]-2-benzopyran (HHCB).
- Phthalic anhydride (PAD).
- o-Dichlorobenzene (o-DCB).
- p-Dichlorobenzene (p-DCB).
Chemicals being considered for review in mid-2026 include:
- 1,2-Dichloropropane (1,2-DCP).
- 1,1,2-Trichloroethane (1,1,2-TCA).
- trans-1,2-Dichloroethylene (trans-DCE).
- Ethylene dibromide (EDB).
- 4,4-(1-Methylethylidene)bis[2, 6-dibromophenol] (TBBPA).
- Phosphoric acid, triphenyl ester (TPP).
Nominees should be scientific experts who have sufficient professional qualifications, including training and experience, to be capable of providing expert comments on the scientific issues for these reviews.
Action: Nominations must be submitted by email to SACC@epa.gov by February 4, 2026.
