2011’s First Violations of the 1997 Ozone Standard/updated

..occurred at Grapevine (91 ppb) and Denton Airport (95ppb) today. They won’t be the last. Read about how they happened in detail here.

Update at 10pm:

In total, there were four violations today. Beside the two above, there was also Keller   (90) and Pilot Point (87) with Frisco coming in right at 85 ppb. 

You can play at home using this TCEQ website. When one or more monitors gets four or more readings of 86 ppb or above during a single ozone season, that means the DFW air plan is officially failing.

Link Between Global Warming and Smog

The Union of Concerned Scientists provides the first evidence of why air quality planning for ozone violations (like DFW) should also be paying attention to climate change,

“Higher ozone levels could trigger 2.8 million additional serious respiratory illnesses and 944,000 extra missed school days in the United States in 2020 that could cost $5.4 billion….

“The study used a mapping model by the Environmental Protection Agency to calculate national impacts and rank the 10 states most likely to be harmed in 2020.”

“In terms of costs, the research found that California would be hit hardest, followed by Texas, New York, Pennsylvania, Illinois, Ohio, Michigan, North Carolina, New Jersey and Virginia. It said these states have large numbers of urban residents, children and seniors as well as high levels of nitrogen oxides and VOC (volatile organic compound) emissions from vehicles and power plants.”
