The US Environmental Protection Agency (EPA), on July 4, 2022, notified its draft revision to the Toxic Substances Control Act (TSCA). This is for risk determination for Perchloroethylene (PCE) risk evaluation to reflect the announced policy changes by ensuring the public is protected from unreasonable chemical risks.

According to the draft, the US EPA after evaluation of use finds PCE as a toxic chemical substance that presents unreasonable risks to health. Although this evaluation does not consider the assumption of workers appropriately wearing personal protective equipment (PPE).

When the decision becomes final, it will override the condition of use-specific no unreasonable risk determinations in the December 2020 PCE risk evaluation and make a revised determination of unreasonable risk for PCE as a whole chemical substance.

The final date for comments on the draft revision is August 1, 2022.
