Methylene Chloride; Regulation Under the Toxic Substances Control Act (TSCA); Compliance Date Extension

The Environmental Protection Agency (EPA or Agency) is finalizing an extension to the compliance dates applicable to certain entities subject to the regulation of methylene chloride promulgated under the Toxic Substances Control Act (TSCA). Specifically, EPA is finalizing an 18-month extension of the Workplace Chemical Protection Program (WCPP) and associated recordkeeping compliance dates for industrial or commercial laboratories that are not owned or operated by Federal agencies or contractors acting on behalf of the Federal government. Under this final rule, all non-Federal laboratories will share the same compliance dates with Federal and Federally contracted laboratories. EPA is finalizing an extension of the compliance dates for associated laboratory activities detailed in this final rule to avoid disruption of important functions of non-Federal laboratories such as the use of environmental monitoring methods needed for cleanup sites and wastewater treatment, as well as activities associated with university laboratories or law enforcement laboratories. This final rule is effective on 15 December 2025. 90 Federal Register (FR) 50894, 13 November 2025; Title 40 Code of Federal Regulations (CFR) Part 751: This final rule and previous actions notified under the symbol G/TBT/N/USA/1988 are identified by Docket Number EPA-HQ-OPPT-2020-0465. The Docket Folder is available on Regulations.gov at and provides access to primary and supporting documents as well as comments…

Proposed rule - The Environmental Protection Agency (EPA) is proposing to address the unreasonable risk of injury to human health presented by methylene chloride under its conditions of use as documented in EPA's June 2020 Risk Evaluation for Methylene Chloride and November 2022 revised risk determination for methylene chloride prepared under the Toxic Substances Control Act (TSCA). 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. Methylene chloride, also known as dichloromethane, is acutely lethal, a neurotoxicant, a likely human carcinogen, and presents cancer and non-cancer risks following chronic exposures as well as acute risks. Central nervous system depressant effects can result in loss of consciousness and respiratory depression, resulting in irreversible coma, hypoxia, and eventual death, including 85 documented fatalities from 1980 to 2018, a majority of which were occupational fatalities (see Unit II.A.). Nevertheless, methylene chloride is still a widely used solvent in a variety of consumer and commercial applications including adhesives and sealants, automotive products, and paint and coating removers. To address the identified unreasonable risk, EPA is proposing to: prohibit the manufacture, processing, and distribution in commerce of methylene chloride for consumer…

    Comment deadline: Closed on 26 June 2025

    Methylene Chloride; Regulation Under the Toxic Substances Control Act (TSCA); Compliance Date Extensions

    The Environmental Protection Agency (EPA or Agency) is proposing to extend the compliance date applicable to certain entities subject to the regulation of methylene chloride recently promulgated under the Toxic Substances Control Act (TSCA). Specifically, EPA is proposing to extend by 18 months the Workplace Chemical Protection Program (WCPP) and the associated recordkeeping compliance dates for laboratories that are not owned or operated by agencies or Federal contractors acting on behalf of the Federal government. Under this proposal, all laboratories, whether federal or not, would have the same compliance dates, which would be aligned with current compliance dates for Federal agencies and Federal contractors. EPA is proposing to extend the compliance dates for associated laboratory activities detailed in this proposal to avoid disruption of important functions such as the use of environmental monitoring methods needed for cleanup sites and wastewater treatment, as well as activities associated with university laboratories. The use of environmental monitoring methods, a common function of non-federal laboratories, is important to EPA's mission to ensure that the air is safe to breathe, water is safe for drinking or recreating, and disposal activities protect the environment. Comments must be received on or before 26 June 2025. 90 Federal Register (FR) 22214, 27 May 2025; Title 40 Code of Federal Regulations (CFR) Part 751: This and previous actions notified under the…

  3. AddendumG/TBT/N/USA/1988/Add.1

    Methylene Chloride; Regulation Under the Toxic Substances Control Act (TSCA)

    The Environmental Protection Agency (EPA or the Agency) is finalizing a rule to address the unreasonable risk of injury to health presented by methylene chloride under its conditions of use. 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 and death 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 an industrial and commercial use of the chemical is being prohibited, provide a time-limited exemption for a critical or essential use of methylene chloride for which no technically and economically feasible safer alternative is available, and protect workers from the unreasonable risk of methylene chloride while on the job. This final rule is effective on 8 July 2024 Title 40 Code of Federal Regulations (CFR) Part 751 This final rule and the proposed rule notified as G/TBT/N/USA/1988 are identified by Docket Number EPA-HQ-OPPT-2020-0465.
