This year is shaping up to be one of the US Environmental Protection Agency’s busiest for chemical regulation since the Toxic Substances Control Act (TSCA) was amended in 2016. The agency is about 3 years behind schedule on issuing regulations on the first 10 high- priority chemicals assessed under the revised TSCA. The EPA found risks to human health for all 10. But so far, it has proposed rules to manage those risks for just half of them: asbestos , carbon tetrachloride , methylene chloride , perchloroethylene , and trichloroethylene . The EPA will likely finalize some of those rules and crank out proposals for the remaining 5 chemicals in 2024. Asbestos will most likely be the first to be regulated this year. In early December, the EPA sent a rule banning the use of chrysotile asbestos to the White House Office of Management and Budget for review. This type © 2024 Chemical & Engineering News
