Peer Review of 2024 Draft Risk Evaluation for 1,1-Dichloroethane and Draft Hazard Assessment for 1,2-Dichloroethane
In July 2024, EPA released for public comment and peer review the draft risk evaluation for 1,1-dichloroethane and the draft hazard assessment for 1,2-dichloroethane (also known as ethylene dichloride) prepared under the Toxic Substances Control Act (TSCA). EPA held a virtual public meeting for the Science Advisory Committee on Chemicals (SACC) to consider and review these draft documents from September 17-19. EPA held a preparatory virtual public meeting on August 27, 2024, for the SACC and the public to consider and ask questions regarding the scope and clarity of the draft charge questions for review. View the SACC meetings using the links found in the "Meeting Viewing Information" box on the right.
On November 27, 2024, EPA released the meeting minutes and final report for the SACC meeting. The documents are posted to docket EPA-HQ-OPPT-2024-0114.
EPA was seeking feedback on the draft hazard assessment for 1,2-dicholorethane in addition to the draft risk evaluation for 1,1-dichloroethane because data on the toxicity of 1,2-dichloroethane is used to fill gaps in the understanding of 1,1-dichloroethane toxicity. This is a well-established risk assessment practice for chemicals that share structural similarities.
Any feedback received from the public and the SACC will be considered in order to inform the final risk evaluations for 1,1-dichloroethane and 1,2-dichloroethane.
