Regulatory Status of Halogenated Solvent Cleaners

This white paper outlines the regulatory status of halogenated solvent cleaners, focusing on solvents such as methylene chloride, perchloroethylene, trichloroethylene, and n-propyl bromide. These solvents are currently under risk evaluation by the U.S. EPA as part of the Toxic Substances Control Act. The paper details the findings of the EPA's evaluations, which identified unreasonable risks to human health and the environment associated with various conditions of use for these chemicals. It also discusses state-level regulations that are emerging in response to these findings, including bans and restrictions on solvent use. The document further presents options for facilities to comply with future regulations, including chemistry and equipment conversions, and highlights considerations for chemical management actions. These considerations include company policies, futureproofing against new regulations, and the importance of ensuring consistent cleaning operations across global manufacturing sites. The paper concludes with insights into the need for stabilizers in vapor degreasing systems to maintain operational efficiency.
