Risk Evaluation for Trichloroethylene (TCE)
Trichloroethylene (TCE) is a volatile organic compound (VOC) widely used in industrial and commercial processes, and limited uses in consumer products. Most of TCE’s annual production volume is used as an intermediate in the manufacture of hydrofluorocarbon (HFC-134a – an alternative to the refrigerant CFC-12). TCE is also used as a degreasing solvent, as a spotting agent for dry cleaning, and in consumer products.

- Review of TCE prior to the Lautenberg Act
- CASRN: 79-01-6
- Initiated: December 19, 2016
- Docket: EPA-HQ-OPPT-2016-0737
This problem formulation refines the scope of the TCE risk evaluation by clarifying the chemical uses that EPA expects to evaluate and describing how EPA expects to conduct the evaluation. This is an important interim step prior to completing and publishing the final risk evaluation. The problem formulation document will be available for comment until July 26, 2018 in the docket listed above.
