Proposed rule - The Environmental Protection Agency (EPA) is proposing to address the unreasonable risk of injury to human health presented by trichloroethylene (TCE) under its conditions of use as documented in EPA's November 2020 Risk Evaluation for TCE and January 2023 revised risk determination for TCE pursuant to the Toxic Substances Control Act (TSCA). TCE is widely used as a solvent in a variety of industrial, commercial and consumer applications including for hydrofluorocarbon (HFC) production, vapor and aerosol degreasing, and in lubricants, greases, adhesives, and sealants. TSCA requires that when EPA determines a chemical substance presents unreasonable risk that EPA address by rule the unreasonable risk of injury to health or the environment and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. EPA determined that TCE presents an unreasonable risk of injury to health due to the significant adverse health effects associated with exposure to TCE, including non-cancer effects (liver toxicity, kidney toxicity, neurotoxicity, immunotoxicity, reproductive toxicity, and developmental toxicity) as well as cancer (liver, kidney, and non-Hodgkin lymphoma) from chronic inhalation and dermal exposures to TCE. TCE is a neurotoxicant and is carcinogenic to humans by all routes of exposure. The most sensitive adverse effects of TCE exposure are non-cancer effects (developmental toxicity and immunosuppression) for acute exposures…
