EPA Proposes To Restrict Certain Persistent, Bioaccumulative, and Toxic Chemicals
June 3, 2019
In a landmark proposed rulemaking on Friday, June 21, 2019, the U.S. Environmental Protection Agency (EPA) proposed to restrict four out of the five chemicals that the agency determined to be persistent, bioaccumulative, and toxic (PBT) pursuant to section 6(h) of the Toxic Substances Control Act (TSCA).1 The following five chemicals are subject to this rulemaking: decabromodiphenyl ethers (DecaBDE); phenol, isopropylated, phosphate (3:1) (PIP (3:1)); 2,4,6-Tris(tert-butyl)phenol (2,4,6-TTBP); pentachlorothiophenol (PCTP); and hexachlorobutadiene (HCBD). To comply with TSCA section 6(h)(3), EPA must issue a final PBT rule by December 21, 2020.
