EPA Releases Draft Exposure Assessments For Trans‑1,2‑Dichloroethylene And 1,2‑Dichloropropane

The U.S. Environmental Protection Agency (EPA) announced on July 31, 2026, that it is advancing its review of trans‑1,2‑dichloroethylene and 1,2‑dichloropropane under the Toxic Substances Control Act (TSCA) “by releasing draft technical support documents that explain how the agency estimates exposure to these common solvents.” According to EPA, “[e]valuating potential risks from these solvents is important because they are widely used in industry and may be present in consumer products and can travel through air and water, leading to possible exposures at work, at home, and in nearby communities.” Under TSCA, EPA is required to consider potentially exposed or susceptible subpopulations, which can include workers, pregnant women, infants and children, and people who live near where these chemicals are used.
