Last year's air quality death spiral in DFW was sometimes explained away as an anomaly because of the severe drought the entire state was going through.

So what's the explanation this year?

With yesterday's high ozone levels sending a 6th monitor into an exceedance of the old 1997 85 parts per billion smog standard, DFW is just one more bad air day away from matching last year's dreadful results. Today's ozone forecast says there should be no high levels of smog in DFW today, even as the temperature reaches for a record high. But then again, they weren't predicted Thursday either.

To give you some idea how rapidly things have gone downhill for air quality in DFW the past two years, just look at the annual numbers. From 2007 to 2010, we had a total of nine monitors register official exceedances of the 85 ppb standard. That's about two monitors a year average. This turns out to be the closest we've ever come to actually meeting the standard. Officials could argue with some justification that air quality was slowly getting better.

On the other hand, during the last two years, we've had 13 monitors record exceedances of the 85 ppb standard, an average of 6.5 a year, and 2012's ozone season is not yet over. You could add up all the exceedances from the four years between 2007 and 2010 and still not equal the number we've experienced in just the last 24 months.

This is not progress.

TCEQ and the gas industry have argued for some time that gas mining couldn't possibly be contributing to smog problems since smog levels were going down as drilling was increasing in DFW. But that's not true anymore. As gas drilling has moved further and further east – into the heart of the non-attainment area, we've seen in increase in ozone concentrations, in exceedances in monitors, and monitors in the eastern part of the Metromess exceeding the standard that hadn't done so in five to seven years.

Meanwhile all other major source categories for air pollution have been decreasing their emissions. Cars, power plants and cement kilns are actually releasing less air pollution now than they were ten or 20 years ago. Only one large specific source category has increased its annual tonnage significantly over that same time – oil and gas.

Is it just a coincidence that smog is getting worse as oil and gas pollution skyrocket – not only in the Barnett Shale that surrounds DFW on three sides, but by all the new oil and gas sources now southeast of Dallas as part of the Haynesville Shale play that are blowing their pollution toward us most of the ozone season? There are now so many gas compressors in Freestone County, less than 75 miles away from the Dallas County line, that their emissions represent the equivalent of over 4 new Big Brown coal plants. What do you think the impact on air quality would be of four large new coal plants located immediately upwind of DFW? Might it look a lot like it does in 2012?

Could it be that the dirty mining of "clean" natural gas is making it impossible for DFW to meet the old 85 ozone standard, much less the new 75 ppb one? That the Devil's Bargain so many former and current elected officials made with the gas operators to grab the cash and run is now coming back to bite them and us in the air quality butt? That was certainly the conclusion of the study we publicized this last Tuesday from the Houston Advanced Research Center:

"Major metropolitan areas in or near shale formations will be hard pressed to demonstrate future attainment of the federal ozone standard, unless significant controls are placed on emissions from increased oil and gas exploration and production….urban drilling and the associated growth in industry emissions may be sufficient to keep the area (DFW) in nonattainment."

It's time for local officials to replace those cash registers in their eyes with gas masks. Because of their rush to make money, they didn't pause to understand how so much new industrial activity could produce smog just like the bad ol' days. They were being paid not to understand. And now 5 to 6 million people who still can't yet breathe safe and legal air are paying the price.
