Atlanta’s 2011 “smog season” was a pretty bad one by any measure. This year Atlanta had 39 ozone violations, or days when ozone concentrations exceeded the 2008 ozone limit set by the U.S. Environmental Protection Agency (EPA) under George W. Bush.
Thirty-nine violations are bad enough, but the real public health tally is actually much worse. EPA’s Clean Air Scientific Advisory Committee (CASAC), the group charged with making science-based recommendations to EPA on air quality standards, unanimously concluded that the limit for ozone should be significantly lowered. After several delays, in July EPA submitted its recommendation for a stronger standard to the White House. On September 2, public health scientists and advocates were dismayed when President Obama announced that he would not consider the recommendation at this time, postponing a stronger standard for several years at least.
