USA - 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 October 26, 2022.This final rule is effective on January 17, 2025.
