"The Obama administration signaled Wednesday that it would scrap a controversial Bush-era rule that set stricter limits for smog but fell short of scientific recommendations.
In a notice filed Wednesday in a federal appeals court, the Justice Department says there are concerns that the revision made by the Bush administration does not adhere to federal air pollution law. The Environmental Protection Agency will propose revised smog standards to protect health and the environment in late December.
'This is one of the most important protection measures we can take to safeguard our health and our environment,' said EPA Administrator Lisa P. Jackson in a statement. 'Reconsidering these standards and ensuring acceptable levels of ground-level ozone could cut health care costs and make our cities healthier, safer places to live, work and play.'
Smog is a respiratory irritant that can aggravate asthma and has been linked to heart attacks."
