"The Obama administration is preparing to unveil an air pollution rule shortly after the midterm elections that could be among the most costly and controversial in history.

The Environmental Protection Agency (EPA) is seeking approval from the White House for a proposal to update the nation’s outdated ozone standards. The agency punted on the air pollution rules three years ago and missed another deadline last year.

Environmental and public health advocates say stronger ozone standards can’t come soon enough. But business groups complain that tougher rules would be 'unrealistic'."
