EPA To Set Stricter Smog Limits

I remember reading a few years ago that the Bush Administration was setting the limits for ground-level ozone lower than what scientists were recommending for human safety.  Good to see the Obama Administration’s EPA get this right.  See the article by the Washington Post on the subject here.  Excerpts below.

“The Environmental Protection Agency on Thursday proposed limiting the allowable amount of pollution-forming ozone in the air from 75 to between 60 and 70 parts per billion for any eight-hour period, significantly tightening rules the Bush administration had set for the nation’s most widespread air pollutant.”

“Depending on the level of the final standard, EPA estimates the proposal will cost between $19 billion and $90 billion to implement and will yield health benefits of between $13 billion and $100 billion. The proposal would translate into thousands of avoided premature deaths by 2020, though the exact number depends on what exact limit the agency adopts.”

“Children and the elderly are particularly vulnerable to smog: Studies show that children who grow up in areas with high ozone concentrations never develop the same lung capacity as ones who live in less polluted areas, and are more likely to develop asthma and other respiratory illnesses.”

“The American Lung Association challenged the Bush ozone rules in federal court, and as a result EPA agreed in September to go back and review more than 1,700 scientific studies and a raft of other materials which served as the basis for the agency’s 2008 decision. EPA also announced that as part of its smog proposal it will also set a secondary, seasonal limit to protect plants and trees from prolonged exposure to ozone.”
