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

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 us
