Former EPA air chief Holmstead discusses court ruling on emissions regulation

As environmental groups and utilities go head to head on mercury emissions regulation of coal-fired power plants, a lengthy legal battle is expected following last month's federal appeals court decision that ruled U.S. EPA's cap-and-trade program for regulating mercury emissions illegal. During today's OnPoint, Jeff Holmstead, head of the environmental strategies group at Bracewell & Giuliani and former air chief at EPA, gives his read on the court's decision. Holmstead explains why he believes existing power plants cannot be expected to meet the 90 percent emissions reduction goal environmental groups are pushing for. Holmstead also gives his views on EPA's California waiver decision on vehicle tailpipe emissions.
