Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA); (49 
page(s), in English)  
6. Description of content:  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 do cumented 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 pr oducts 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 necessa ry 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, a nd 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 W arming 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 already been phased o ut, 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 G/TBT/N/USA/2024
