EPA Finalizes Rules to Phase Out Hazardous Solvents TCE and PCE
The U.S. Environmental Protection Agency (EPA) has finalized rules to phase out the use of two hazardous solvents: trichloroethylene (TCE) and perchloroethylene (PCE). These actions aim to protect public health and the environment by significantly reducing exposure to these chemicals.
The TCE ban prohibits most uses within a year, including those in consumer products. Limited workplace exceptions will be phased out over a longer period, with stringent worker safety requirements in place, including a revised inhalation exposure limit to reduce workplace exposure by 97%. The rule also allows for essential laboratory use and proper disposal of TCE wastewater for 50 years to support cleanup activities.
For PCE, the rule includes a 10-year phase-out for dry cleaning to protect workers and customers. Manufacturing, processing, and distribution of PCE for most consumer and industrial uses will be significantly reduced within three years. Stringent workplace controls will be mandated for continuing uses, while support for small businesses, such as dry cleaners, will be provided through compliance guidance and potential funding opportunities.
Small businesses interested in this new development can learn more about EPA’s actions on perchloroethylene (PCE) and trichloroethylene (TCE).
EPA will host a public webinar on January 15, 2025, to explain the PCE final rule and its implementation.
