The latest attempt to block a federal rule addressing mercury pollution from power plants has failed.

The Mercury and Air Toxics Standards target mercury pollution from coal-fired power plants, which are the largest source of the toxin. Mercury can cause health problems, especially in children.

Last year, the Supreme Court sent the rule back to the lower courts after finding that the Environmental Protection Agency hadn’t adequately considered cost when formulating the rule. The agency has since done that.

Today the US Supreme Court ruled against the Environmental Protection Agency in a suit that challenged one of the Obama administrations most ambitious environmental plans. 

The question at the heart of the case was this: should the EPA have considered cost before issuing a rule designed to cut mercury emissions from coal-fired power plants. In the 5-4 decision, justices ruled in favor of the states and industry groups that brought the suit essentially saying yes, the EPA should have considered cost. 


The nation's coal- and oil-fired power plants, will be forced to reduce their emissions orshut down, under a federal regulation released by the Environmental Protection Agency today/Wednesday. 

The Powder River Basin Resource Council’s Shannon Anderson doubts any Wyoming plant will go out of operation, but she says several need to clean their emissions.
