WASHINGTON, Nov. 25 (UPI) -- The U.S. Supreme Court agreed Tuesday to consider whether the cost of federal limits on mercury emissions outweigh the benefits.
The regulations set by the Environmental Protection Administration in emissions from oil- and coal-fired electrical generating plants have been challenged by a group of states and industry groups. Sixteen other states support the federal action, arguing that air-born pollutants cross state lines and that regulation at the federal level is needed.
