The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on June 24, 2020, announcing the availability of the final Toxic Substances Control Act (TSCA) risk evaluation for methylene chloride.  85 Fed. Reg. 37942.  This is the first risk evaluation that EPA has completed under the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg Act) amendments to TSCA.  After evaluating 53 conditions of use of methylene chloride, EPA determined that 47 conditions of use present an unreasonable risk of injury to health, while six do not present an unreasonable risk.  EPA also determined that methylene chloride does not present an unreasonable risk to the environment under any conditions of use.  Release of a final risk evaluation is the last step in the TSCA Section 6(b) process and will guide EPA’s efforts in applying Section 6(a) to reduce human exposure to methylene chloride “so that the chemical … no longer presents such risk.”  EPA states that it “will now begin the process of developing ways to address the unreasonable risks identified and has up to one year to propose and take public comments on any risk management actions.”  For more information, please read the full memorandum.
