The U.S. Environmental Protection Agency (EPA) is proposing the first chemical it may ban under an expanded chemical safety law.

The agency said it identified health risks to workers and consumers during a 2014 assessment of the chemical. Officials say that banning it—the first time “in a generation” the agency has been able to restrict chemicals already in use—would be good for public health.

TCE was one of 10 chemicals the EPA identified in November as candidates for restriction under the Chemical Safety for the 21st Century Act. The law requires the EPA to take three years to study if the chemicals present risks to human health and the environment, and then consider whether or not to ban them.
