Peer Review for Evaluating 1,1,2-TCA; 1,2-DCP; TBBPA; EDB; and tDCE

In June 2026, EPA released draft documents supporting the risk evaluations for 1,1,2-trichloroethane;  4,4'-(1-methylethylidene)bis[2,6-dibromophenol] (TBBPA); 1,2-dichloropropane;  ethylene dibromide; and trans-1,2-dichloroethylene under the Toxic Substances Control Act (TSCA) for public comment and peer review.  

EPA will hold a virtual public meeting on August 3-7, 2026, of the Science Advisory Committee on Chemicals (SACC) to discuss the technical support documents supporting the draft risk evaluations for 1,2-DCP; 1,1,2-TCA; trans-DCE; TBBPA and EDB. Additionally, EPA will hold a preparatory virtual public meeting on July 14, 2026, for the SACC and the public to consider the scope and clarity of the draft charge questions for the peer review. EPA will publish registration links for the August SACC meeting and July preparatory meeting on this page approximately one month prior to each meeting. Read a prepublication version of the Federal Register Notice announcing the peer review. Upon publication of the Federal Register Notice, the supporting documents will be available via docket EPA-HQ-OPPT-2026-2246 on regulations.gov.    

On January 5, 2026, EPA published a Federal Register notice requesting nominations of prospective ad hoc expert reviewers to assist the SACC with its peer review. The nomination period ended on February 4, 2026. After reviewing the nominations, EPA solicited public comments on ad hoc reviewers under consideration. Biographies of the selected reviewers are available via docket EPA-HQ-OPPT-2025-3358  on regulations.gov.
