The Environmental Protection Agency announced the proposed risk management rule for perchloroethylene (PCE) under the Toxic Substances Control Act. This proposal would prohibit all consumer uses, use in dry cleaning, and most industrial and commercial uses of PCE. Permitted uses would be subject to a workplace chemical protection program along with recordkeeping and downstream notification requirements. The rule also provides certain time-limited exemptions.
