1,1,2-Trichloroethane Draft Risk Evaluation Under the Toxic Substances Control Act (TSCA); Notice of Availability and Request for Comment
Published Date: 7/29/2026
Notice
Summary
The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on the draft risk evaluation under the Toxic Substances Control Act (TSCA) for 1,1,2-trichloroethane. The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use (COUs), including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, and without consideration of costs or non-risk factors. EPA is seeking comment on the draft risk evaluation for 1,1,2-trichloroethane.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 1 costs, 1 mixed.
EPA requests detailed industry data
EPA is asking manufacturers, importers, users, and others to submit detailed information about imports, quantities, manufacturing (including whether it is a primary product or a byproduct), uses in adhesives, laboratory use, cleaning and degreasing, transport containers, remediation practices, worker schedules and monitoring data, respirator and dermal PPE usage, and environmental releases. EPA specifically asks whether the default of 350 operating days per site-year is appropriate for manufacturing facilities and requests data to refine exposure assumptions.
Final evaluation will drive TSCA section 6 decisions
After public comments and peer review, EPA will issue a final risk evaluation for 1,1,2-trichloroethane and must use that final evaluation under TSCA section 6 to determine whether the chemical presents an unreasonable risk. EPA will not consider costs or other non-risk factors during the risk evaluation.
Draft risk evaluation released; comments open
EPA released a draft risk evaluation for 1,1,2-trichloroethane and is asking the public to submit comments by September 28, 2026. The notice tells interested parties how to submit comments (Docket ID EPA-HQ-OPPT-2018-0421) and warns not to submit Confidential Business Information through Regulations.gov.
Preliminary finding: unreasonable health risk
EPA preliminarily determined, based on the draft risk evaluation, that 1,1,2-trichloroethane poses an unreasonable risk to human health for certain conditions of use. The draft assessed risks to workers (including occupational non-users), consumers, the general population (including fenceline communities and potentially exposed or susceptible subpopulations), and to aquatic and terrestrial species.
