On January 8, 2021, the U.S. Environmental Protection Agency (EPA) released the final risk evaluation for 1,4-dioxane. 86 Fed. Reg. 1495. The final risk evaluation identifies unreasonable risk to workers for 13 out of 24 conditions of use. EPA states that it found no unreasonable risk to the general population and the environment. EPA notes that it also published a supplemental analysis to the draft risk evaluation that evaluated eight additional conditions of use for 1,4-dioxane present as a byproduct in consumer products. According to EPA, after “carefully considering” public comments on the supplemental analysis, it found no unreasonable risk for these consumer uses. EPA has to date completed risk evaluations on eight of the “first ten” chemicals selected for risk evaluation. For more information on the next steps for this risk evaluation, please read the full memorandum.
