New TSCA Restrictions for 5 PBT Chemicals

LION - TSCA, as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act (LCSA), requires EPA to evaluate the risks of chemicals on the TSCA inventory.

The law also directs EPA to take expedited action to address the risks of some specific substances that had been identified in a previous TSCA Work Plan. These include persistent, bioaccumulative, and toxic (PBT) chemicals that EPA believes pose a high or moderate risk to human health of the environment.

EPA recently completed risk evaluations and established new regulatory management programs for five PBT chemical substances. For many of these chemicals, EPA will prohibit all manufacture, import, processing, and distribution in commerce.

All five Final Rules take effect on February 5, 2021.

The five PBT chemicals for which EPA issued new rules are:
  • Pentachlorothiophenol (PCTP)
  • Hexachlorobutadiene (HCBD)
  • Decabromodiphenyl ether (DecaBDE)
  • Phenol, Isopropylated Phosphate 3:1 (PIP 3:1)
  • 2, 4, 6-tris(tert-butyl)phenol (2, 4, 6-TTBP)
The five new rulemakings illustrate EPA's broad authority under TSCA to restrict how chemicals are made and used in order to protect human health and the environment. Read on for details about new restrictions EPA has put in place for these chemicals.
