Oklahoma In Compliance With Current Ozone Standard

Credit Oklahoma Dept. of Transportation

Oklahoma is in compliance with the National Ambient Air Quality Standard for ozone as the 2014 ozone season draws to a close.

Compliance is determined by an average at each ozone monitoring site in the state. Drought and high temperatures in 2011 and 2012 resulted in the state exceeding the standard at monitors across the state. The 2013 and 2014 ozone seasons have been dramatically better.

While the control of emissions contributed to the lower ozone readings, other factors including weather, fewer wildfires and less demand for electricity also played a role.

You can’t see it from street, or when you look out the window of Glen Jones’ parents’ house, but the Wilcox Refinery is still here. Parts of it, anyway.

In December 2013, the abandoned refinery complex near Bristow became Oklahoma’s newest federal Superfund site. The Wilcox Refinery closed more than 50 years ago, but lead and other toxic chemicals remain, and residents are uneasy about the long cleanup ahead.
