EPA to Hold Webinar on Chemicals Identified for Expedited Action Under TSCA

Published August 30, 2017

​Next Thursday, Sept. 7, EPA will host a webinar to explain the process for gathering use and exposure information on five persistent, bioaccumulative, and toxic (PBT) chemicals under the amended Toxic Substances Control Act (TSCA). New requirements in the Frank R. Lautenberg Chemical Safety for the 21st Century Act, which finalized reform of TSCA in June 2016, direct EPA to expedite action to reduce exposures for certain PBT chemicals. The five PBT chemicals identified for action by EPA according to these requirements include decabromodiphenyl ethers (decaBDE); hexachlorobutadiene (HCBD); pentachlorothiophenol (PCTP); phenol, isopropylated, phosphate (3:1); and 2,4,6-tris(tert-butyl) phenol.

EPA must propose rules for these five chemicals by June 22, 2019. The agency is in the process of identifying where the chemicals are used and how people are exposed to them. Participants in the Sept. 7 webinar will learn about how to provide information to EPA on uses of these five chemicals.

According to EPA, decaBDE is used as a flame retardant in textiles, plastics, wiring insulation, and building and construction materials, and 2,4,6-tris(tert-butyl) phenol is an antioxidant that can be used as a fuel, oil, gasoline, or lubricant additive. HCBD is used in the manufacture of rubber compounds and as a solvent, and PCTP is used as an agent to make rubber more pliable in industrial applications. EPA notes that phenol, isopropylated, phosphate (3:1) is used as a flame retardant in consumer products.

Webinar participants will have the opportunity to provide comments on the uses of the five chemicals following EPA’s presentation. For those unable to attend on Sept. 7, the agency has established public dockets for each of the five PBT chemicals. Interested parties can use the dockets to submit information on exposure and use that may help EPA’s rulemaking efforts. The deadline for submitting comments and information is Dec. 8, 2017.

The webinar will be held from 2 to 4 p.m. ET on Sept. 7. Registration is free and available through Eventbrite.
