Perchloroethylene (PCE) and Carbon Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA); Compliance Date Extensions

The U.S. Environmental Protection Agency (EPA or Agency) is finalizing an extension of certain compliance dates applicable to certain entities subject to the risk-management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) under the Toxic Substances Control Act (TSCA). EPA is extending certain Workplace Chemical Protection Program (WCPP) compliance dates for non-federal owners and operators to match the existing compliance dates for federal agencies and their contractors. For both PCE and CTC, this action extends the compliance date for initial monitoring for inhalation exposure to 21 June 2027, and extends the compliance date to meet the existing chemical exposure limit (ECEL), establish a regulated area, institute a workplace information and training program, provide any required respiratory personal protective equipment (PPE), and establish a respiratory PPE program to 20 September 2027. For PCE, EPA is also extending the compliance date for federal entities to institute a workplace information and training program to 20 September 2027, and for non-federal entities to establish and implement an exposure control plan to 20 December 2027. This final rule is effective on 28 July 2026. 91 Federal Register (FR) 47145, 28 July 2026; Title 40 Code of Federal Regulations (CFR) Part 751: This final rule and the proposed rule notified as G/TBT/N/USA/2024/Rev.1 are identified by Docket Number EPA-HQ-OPPT-2026-0992.

Proposed rule - The Environmental Protection Agency (EPA or Agency) is proposing to extend certain compliance dates applicable to certain entities subject to the regulation of perchloroethylene (PCE) and carbon tetrachloride (CTC) under the Toxic Substances Control Act (TSCA). EPA is proposing to extend certain Workplace Chemical Protection Program (WCPP) compliance dates for non-federal owners and operators to match the compliance dates for federal agencies and their contractors. For both PCE and CTC, this proposal would extend the compliance date for initial monitoring for inhalation exposure to 21 June 2027, and extend the compliance date to meet the existing chemical exposure limit (ECEL), establish a regulated area, provide any required respiratory personal protective equipment (PPE), and establish a respiratory PPE program to 20 September 2027. For PCE, EPA is also proposing to extend the compliance date for non-federal entities to establish and implement an exposure control plan to 20 December 2027.

  3. AddendumG/TBT/N/USA/2024/Add.1

    Carbon Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA)

    The Environmental Protection Agency (EPA or 'Agency') is finalizing a rule to address the unreasonable risk of injury to health presented by carbon tetrachloride (CTC) under its conditions of use. The Toxic Substances Control Act (TSCA) requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so that the chemical no longer presents unreasonable risk. EPA's final rule will establish workplace safety requirements for most conditions of use, including the condition of use related to the making of low Global Warming Potential (GWP) hydrofluoroolefins (HFOs); prohibit the manufacture (including import), processing, distribution in commerce, and industrial/commercial use of CTC for conditions of use where information indicates use of CTC has ceased; and establish recordkeeping and downstream notification requirements. The use of CTC in low GWP HFOs is particularly important in the Agency's efforts to support the American Innovation and Manufacturing Act of 2020 (AIM Act) and the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, which was ratified on 26 October 2022. This final rule is effective on 17 January 2025. 89 Federal Register (FR) 103512, 18 December 2024; Title 40 Code of Federal Regulations (CFR) Part 751: This final rule and the proposed rule notified as G/TBT/N/USA/2024 is identified by Docket Number…

    Carbon Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA)

    Proposed rule - The Environmental Protection Agency (EPA) is proposing to address the unreasonable risk of injury to human health presented by carbon tetrachloride (CTC) under its conditions of use as documented in EPA's 2020 Risk Evaluation for Carbon Tetrachloride and 2022 Revised Unreasonable Risk Determination for Carbon Tetrachloride pursuant to the Toxic Substances Control Act (TSCA). CTC is a volatile, organic compound that is primarily used as a feedstock (i.e., processed as a reactant) in the making of products such as refrigerants, aerosol propellants, and foam-blowing agents. TSCA requires that EPA address by rule any unreasonable risk of injury to health or the environment identified in a TSCA risk evaluation and apply requirements to the extent necessary so that the chemical no longer presents unreasonable risk. EPA determined that CTC presents an unreasonable risk of injury to health due to cancer from chronic inhalation and dermal exposures and liver toxicity from chronic inhalation, chronic dermal, and acute dermal exposures in the workplace. To address the identified unreasonable risk, EPA is proposing under TSCA to establish workplace safety requirements for most conditions of use, including the condition of use related to the making of low Global Warming Potential (GWP) hydrofluoroolefins (HFOs), prohibit the manufacture (including import), processing, distribution in commerce, and industrial/commercial use of CTC for conditions of use where information…
