Sunscreen? Check. Hydration? Check. Oxygen tank?
Check.

Monday it was the Frisco monitor with a violation of the 1997 eight-hour ozone standard we’re still trying to meet in 2011. Tuesday it was Denton. Today…..by 11 am Rockwall shot up to 99 ppb which isn’t a good sign at all. Look for one or more monitors to trip again by the time the sun sets. You can keep track of your own deteriorating air quality here.

Update:
And so Wednesday’s final tally produced the single worst bad air day in DFW this summer, as well as the worst ozone season in five years. Six monitors exceeded the 1997 8-hour, 85 ppb federal standard that the current TCEQ clean air plan is supposed to meet: Frisco, Denton, Dallas North, Rockwall, Grapevine, and Pilot Point. Five of those monitors recorded  their highest readings for this summer. Combined with Tuesday’s violation in Pilot Point (which we missed), today’s smog levels make that monitor the fourth one in DFW now totally out of compliance with the 85 standard.  And folks, we haven’t had four monitors out of compliance with the 1997 standard since 2007.
