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/2008/Rev.1 are identified by Docket Number EPA-HQ-OPPT-2026-0992.

AddendumG/TBT/N/USA/2008/Add.2
Perchloroethylene (PCE); Regulation Under the Toxic Substances Control Act (TSCA); Request for Comment
The U.S. Environmental Protection Agency (EPA or Agency) is seeking public comment to inform its reconsideration of the Toxic Substances Control Act (TSCA) regulation for perchloroethylene (PCE). As promulgated in December 2024, the PCE risk management action addressed the unreasonable risk of injury to health presented by PCE under its conditions of use by requiring various workplace exposure controls, prohibiting certain industrial and commercial uses, and preventing consumer access to the chemical, among other provisions. This request for public comment follows the filing of several legal challenges to the rule in 2025, and EPA's subsequent determination that the PCE regulation under TSCA should be reconsidered through further rulemaking. EPA intends to consider information received in response to this public comment solicitation, and other reasonably available information, to inform the development of any proposed rule to amend the PCE regulation as appropriate. Comments must be received on or before 29 August 2025. 90 Federal Register (FR) 35858, 30 July 2025: This action and previous actions notified under the symbol G/TBT/N/USA/2008 are identified by Docket Number EPA-HQ-OPPT-2020-0720.

AddendumG/TBT/N/USA/2008/Add.1
Perchloroethylene (PCE); 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 perchloroethylene (PCE) 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, among other things, prevent serious illness associated with uncontrolled exposures to the chemical by preventing consumer access to the chemical, restricting the industrial and commercial use of the chemical while also allowing for a reasonable transition period where the industrial and commercial use of the chemical is being prohibited, providing a time-limited exemption for a critical or essential use of PCE for which no technically and economically feasible safer alternative is available, and protecting workers from the unreasonable risk of PCE while on the job. This final rule is effective on 17 January 2025. 89 Federal Register (FR) 103560, 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/2008 are identified by Docket Number EPA-HQ-OPPT-2020-0720.

Comment deadline: Closed on 15 August 2023
Perchloroethylene (PCE); 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 perchloroethylene (PCE) under its conditions of use as documented in EPA's December 2020 Risk Evaluation for PCE and December 2022 revised risk determination for PCE prepared under the Toxic Substances Control Act (TSCA). PCE is a widely used solvent in a variety of occupational and consumer applications including fluorinated compound production, petroleum manufacturing, dry cleaning, and aerosol degreasing. EPA determined that PCE presents an unreasonable risk of injury to health due to the significant adverse health effects associated with exposure to PCE, including neurotoxicity effects from acute and chronic inhalation exposures and dermal exposures, and cancer from chronic inhalation exposures to PCE. 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 the chemical no longer presents unreasonable risk. PCE, also known as perc and tetrachloroethylene, is a neurotoxicant and a likely human carcinogen. Neurotoxicity, in particular impaired visual and cognitive function and diminished color discrimination, are the most sensitive adverse effects driving the unreasonable risk of PCE, and other adverse effects associated with exposure include central nervous system depression, kidney and liver effects…
