Regulation of Methylene Chloride

In May 2024, the US Environmental Protection Agency (EPA) issued a final rule regulating methylene chloride (also known as DCM or Dichloromethane) under the Toxic Substances Control Act (TSCA). The regulation prohibits most industrial and commercial uses of methylene chloride and creates strict workplace protections for 13 conditions of use that are permitted under the new rule. Detailed information about the EPA ruling, including the full text of the regulation, is available on the EPA website. For documents relating to this topic please visit The Workplace Chemical Protection Program and Appendix A: Operation Specific Exposure Control Plan
