Breaking: Supreme Court to Review EPA Mercury Rules

Just announced in the last hour:

The U.S. Supreme Court agreed to decide whether the Obama administration went too far with new power-plant pollution caps the government estimates will cost almost $10 billion a year.

The justices today said they will hear industry and state contentions that the Environmental Protection Agency didn’t adequately consider those costs when it limited mercury and other hazardous power-plant pollutants. The affected companies include American Electric Power Co. (AEP)Duke Energy Corp. (DUK) and Southern Co. (SO)

High court review of the rule threatens to stop a legal winning streak for EPA air-pollution regulations. In June, the Supreme Court upheld the agency’s requirement that power plants, refineries and chemical factories curb their carbon emissions. In April, the justices backed a rule targeting pollutants that cause smog and acid rain across state lines.

The mercury rules are some of the stupidest rules the EPA has ever promulgated, so let’s hope this appeal succeeds.
