Lynn L. Bergeson, “EPA Proposes Revised PBT Rules for decaBDE and PIP (3:1),” Chemical Processing, December 11, 2023.

It seems like yesterday when the U.S. Environmental Protection Agency (EPA) issued a final rule prohibiting isopropylated phosphate (3:1) (PIP (3:1)), and for many in the manufacturing sector, the world got a little bit crazier. The EPA vowed to revise the final rule and did so on Nov. 24, 2023. The EPA’s proposal would amend the regulations for decabromodiphenyl ether (decaBDE) and 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.
