Mercury and Air Toxics Rule for power plants

In December 2011, EPA's Mercury and Air Toxics Rule placed the first-ever national limit on the amount of mercury, acid gases, and other toxic pollution that power plants can emit. 

Support for these standards is widespread and diverse. EPA received more than 800,000 comments from the public in support of the mercury standards. Additionally, numerous utilities, states, mayors, public health groups, environmental groups, faith groups, small business groups, the NAACP, moms, scientists, sportsmen and the League of United Latin American Citizens have all supported the Mercury and Air Toxics Standards.

A three- judge panel of the U.S. Court of Appeals for the D.C. Circuit upheld the Mercury and Air Toxics Standards in April 2014.
