On April 21, 2026, the Asbestos Disease Awareness Organization (ADAO) filed a federal lawsuit against the U.S. Environmental Protection Agency (EPA) and its Administrator Lee Zeldin in the U.S. District Court for the District of Columbia. The complaint, filed as Case No. 1:26-cv-01350, seeks to compel the EPA to fulfill a mandatory, non-discretionary duty under the Toxic Substances Control Act (TSCA), a duty that has gone unfulfilled for over a year, leaving millions of workers and their families exposed to the continuing hazard of legacy asbestos.
