Air Toxics: Mercury & Power Plants

The U.S. Environmental Protection Agency exempted power plants from Clean Air Act regulations, even though these power plants emit into the air tons of mercury and other toxins—known threats to human health.

In February 2008, a federal appeals court ruled that the EPA did not have the authority to exempt the power plants.
