2 More Ozone Violations Wednesday – 2 More and It’s Another Failed Year

DFW saw two more ozone violations occur on Wednesday, both at sites that had already tripped once in June. That means that the area has two monitoring sites that are already halfway to the four violations that would render 2011 another official clean air failure. All it takes are four separate eight-hour violations of the ozone standard at any one site for EPA to declare DFW in continuing non-attainment of the old 1997 85 ppb ozone/smog standard.
