Decabromodiphenyl Ether and Phenol, Isopropylated Phosphate (3:1); Revision to the Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under the Toxic Substances Control Act (TSCA)

The Environmental Protection Agency (EPA or Agency) is finalizing revisions to the regulations for decabromodiphenyl ether (decaBDE) and phenol, isopropylated phosphate (3:1) (PIP (3:1)), two of the five persistent, bioaccumulative, and toxic (PBT) chemicals addressed in final rules issued under the Toxic Substances Control Act (TSCA) in January 2021. After receiving additional comments, the Agency has determined that revisions to the decaBDE and PIP (3:1) regulations are necessary to address implementation issues and to further reduce the potential for exposures to decaBDE and PIP (3:1) for humans and the environment to the extent practicable.
