The webinar will take place Thursday, September 7, 2017 at 2 pm EDT.


EPA’s Office of Pollution Prevention and Toxics is hosting a webinar to explain to interested parties the process for gathering use and exposure information on five persistent, bioaccumulative and toxic (PBT) chemicals to be regulated under the amended Toxic Substances Control Act (TSCA). This webinar will provide background on new requirements for certain PBT chemicals and explain how interested parties can provide use information to EPA.

Under TSCA section 6(h), EPA is required to take expedited regulatory action to address risks and exposures from certain PBT chemicals. The five PBT chemicals that have been identified under TSCA section 6(h)(1) for action include:

  • Decabromodiphenyl ethers (DecaBDE), used as a flame retardant in textiles, plastics, wiring insulation, and building and construction materials;

  • Hexachlorobutadiene (HCBD), used as a solvent in the manufacture of rubber compounds and as hydraulic, heat transfer or transformer fluid;

  • Pentachlorothiophenol (PCTP), used as a mercaptan (sulfur) cross-linking agent to make rubber more pliable in industrial uses;

  • Phenol, isopropylated, phosphate (3:1), used as a flame retardant in consumer products and as lubricant, hydraulic fluid, and other industrial uses; and

  • 2,4,6-Tris(tert-butyl) phenol, an antioxidant that can be used as a fuel, oil, gasoline or lubricant additive.

During the webinar, there will be an opportunity for the public to provide input on uses of these five PBT chemicals.

Who should attend:

This webinar is for parties involved with or concerned about PBT chemicals under TSCA section 6(h). Following the presentation, there will be an opportunity for participants to provide comments on uses of each PBT chemical.
