FACT SHEET 2024 Final Risk Management Rule for Trichloroethylene under TSCA What is Trichloroethylene (TCE)? Trichloroethylene (CASRN 79-01-6) - also called TCE - is a nonflammable, colorless liquid and a volatile chemical with a somewhat sweet odor. TCE is used in a variety of industrial, commercial, and consumer applications including in industrial cleaning and degreasing, lubricants, adhesives and sealants, paints and coatings, automotive care products, cleaning and furniture care products, and other miscellaneous products. In December 2024, EPA issued a final rule regulating TCE under the Toxic Substances Control Act (TSCA) to protect people from health risks including liver cancer, kidney cancer, and non-Hodgkin's lymphoma. TCE also causes damage to the central nervous system, liver, kidneys, immune system, reproductive organs, and causes fetal heart defects. Who is subject to the TCE regulation? Anyone who manufactures (including imports), processes, distributes in commerce, uses, or disposes of TCE or products containing TCE may be impacted by EPA's regulation of the chemical. The table below is a summary of key points; full details are in the final rule. What is the TCE regulation1 under TSCA? SEPA All uses of TCE are eventually prohibited Prohibitions for Consumer Uses Workplace Chemical Protection Program A workplace chemical protection program (WCPP) is required for a limited number of conditions of use of TCE where a phase-out will take longer than one year. Some of these uses include: Domestic manufacturing. Import. Processing as a reactant/intermediate. Processing into formulation, mixture or reaction product. Recycling. Use as a processing aid in select manufacturing applications. Use as an adhesive and sealant for essential aerospace applications. Use in batch vapor degreasing for land-based DoD defense systems. Use as a solvent in closed-loop batch vapor degreasing for rayon fabric scouring for end use in rocket booster nozzle production. Use in closed-loop or open-top batch vapor degreasing for essential aerospace parts and narrow tubing used for medical devices. Use for vessels of the Armed Forces and their systems. Use as a solvent in closed-loop vapor degreasing necessary for rocket engine cleaning. Certain types of disposal. The WCPP requires owners and operators of facilities using TCE to meet new inhalation exposure limits (e.g., interim ECEL: 0.2 ppm as an 8-hour TWA). Additional details on the WCPP requirements and compliance timeframes are available on page 3. Manufacturing TCE for consumer uses is prohibited after March 17, 2025. Processing and distributing TCE for consumer uses is prohibited after June 16,2025. Prohibitions for Industrial and Commercial Uses Manufacturing TCE for industrial and commercial uses is prohibited after March 17, 2025. Processing TCE for industrial and commercial uses is prohibited after June 16, 2025, and industrial and commercial uses of TCE are prohibited after September 15, 2025. Select uses may continue temporarily under an extended phase- out or TSCA Section 6(g) exemption. Regulatory Threshold Products containing TCE up to 0.1% by weight are excluded from this regulation. Other Workplace Controls There are other workplace controls for use in energized electrical cleaner and disposal at cleanup sites and water treatment facilities (see § 751.317 and § 751.319). 1 Details of these requirements, including longer phases-outs and time-limited section 6(g) exemptions, are in 40 CFR Part 751, subpart D, available at https://www.federalreqister.gOv/documents/2024/12/17/2024-29274/trichloroethvlene-tce-requlation-under- the-toxic-substances-control-act-tsca and https://www.ecfr.gov/current/title-40/part-751. ^ December 2024 EPA Document #740F24015 ------- FACT SHEET 2024 Final Risk Management Rule for Trichloroethylene under TSCA Compliance Timelines for Prohibitions EPA prohibits the manufacturing (including importing), processing, and distribution in commerce of TCE for all uses.
