Study: Gas Drilling “Significantly” Increasing DFW Smog
In the middle of another bad North Texas ozone season, a new study by a Houston research consortium concludes that Barnett Shale natural gas facilities "significantly" raise smog levels in DFW, affecting air quality far downwind.
According to the study, ozone impacts from gas industry pollution are so large, they'll likely keep North Texas from being able to achieve the EPA's new 75 parts per billion (ppb) ozone standard.
Author Eduardo P. Olaguer, a Senior Research Scientist and Director of Air Quality Research at the Houston Advanced Research Center, concludes that, "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."
Olaguer's article describing his study was recently published in the July 18th edition of the Journal of the Air & Waste Management Association. It's the first independent study to examine specific North Texas ozone impacts from the gas industry.
Environmental groups say air pollution from natural gas sources is already making it impossible for DFW to meet even the obsolete 15-year old standard of 85 ppb. So far in 2012, five monitors have violated that level of smog despite a state plan that Austin guaranteed would reduce ozone concentrations in DFW to record lows this year. Counting 2012's failure, DFW has been in continual violation of the Clean Air Act for its smog pollution since 1991.
"This study is proof we need a regional strategy of self-defense to reduce air pollution from the gas industry," said Downwinders at Risk Director Jim Schermbeck, whose group has been leading the fight to reduce smog-forming pollution from gas sources for two years now. "TCEQ and EPA are not doing enough to rein-in these facilities. Despite their official plans, our air is getting dirtier, not cleaner because gas pollution is still under-regulated. It's time for us to do more at the local level."
Schermbeck suggested the study could make a difference in the upcoming city council vote on a new Dallas gas drilling ordinance.
"Dallas has a chance to react positively to this new evidence by adopting the nation's first policy aimed at mitigating the tons of new pollution caused by gas mining in its new drilling ordinance. That would be a very large step forward in advancing regional clean air goals."
A city-wide coalition of neighborhood, homeowners, and environmental groups has been urging the Dallas city council to require gas operators to reduce as much air pollution as they release through funding of anti-pollution measures across the city. The Houston Center study gives them a lot of fresh arguments.
According to it, "…oil and gas activities can have significant near-source impacts on ambient ozone, through either regular emissions or flares and other emission events associated with process upsets,and perhaps also maintenance, startup, and shutdown of oil and gas facilities."
In fact, just routine emissions from a single gas compressor station or large flare can raise ozone levels by 3 parts per billion as far as five miles downwind, and sometimes by 10 ppb or more as far as 10 miles downwind.
Those impacts rival the size of smog effects traced back to the Midlothian cement kilns or East Texas coal-fired power plants by previous studies.
As the study notes, "Given the possible impact of large single facilities, it is all the more conceivable that aggregations of oil and gas sites may act in concert so that they contribute several parts per billion to 8-hr ozone during actual exceedances."
This conclusion directly contradicts the stance of the Natural Gas industry and the Texas Commission on Environmental Quality, both of which deny that Barnett Shale gas emissions are large enough or located in areas that can influence DFW ozone levels.
But the Houston study is based in part on data collected by industry, as well as information from the city-sponsored "Fort Worth Study," and citizen-sponsored testing in the town of DISH in Denton County. It also uses a kind of computer modeling that allows for a more realistic understanding of how large releases from gas facilities can increase ozone pollution than the one the TCEQ uses. It's the most sophisticated challenge yet to the state and industry's claim that gas emissions do not constitute a large threat to DFW air quality.
"This is reality-based science, not the ideologically-influenced happy talk that's coming out of TCEQ these days," said Schermbeck. "Local governments in North Texas, especially those that are traditional allies of clean air, need to pay close attention and act on it."

Gas Patch Pollution Linked to First Alamo City Ozone Violation
Ever since smog was an issue in Texas starting in the last 1980's, the two largest metropolitan areas have been duking it out for worst air in the state. Houston was the undisputed champion for awhile, but as of the last couple of years, Dallas-Ft. Worth has been neck and neck, and last, year, even posted worse numbers than Bayou City. No other city even came close.
Until now.
For the first time ever, San Antonio has a monitor in violation of the national ozone standard. It's the new standard of 75 parts per billion, so it's still way ahead of Houston and Ft. Worth that are still have chronic problems meeting the old 1997 85 ppb standard. But it's still a milestone.
What factors helped push SA over the line? Well, theres the significant growth of the larger metropolitan area itself, and out-of-state power plants that will now not be better controlled because of Team Perry's victory over the cross state pollution rules, and oh yeah, gas patch air polluion from the Eagle Ford Shale that's up wind of San Anontio:
"Increased air pollution from the oil and gas boom of the Eagle Ford Shale is believed to be a factor, in addition to local sources and pollution coming from Mexico, East Texas and the East Coast."
Study Links Utah’s “Wintertime Ozone” with Gas Patch Pollution
The rural Unita Basin in Utah has had some of the worst smog in the nation – in the middle of winter, with snow on the ground. That's not supposed to happen, but 10,000 gas wells, along with car and truck traffic combine to make it happen. A new $5 million study confirms that the smog-forming gas patch pollution is a major cause. "That seems to be a pretty strong link," said the study's main researcher.
Isn't the fact that there's that a smog problem in rural Utah where none existed before fracking began sufficient evidence of the link between fracking and smog to warrant cities already suffering smog problems like Dallas to take precautions before the open the door to fracking in the city limits?
The Perry-TCEQ Plan for Cleaner Air: More Coal
When it rains, it pours, or in this case, spews.
After getting a favorable ruling that struck down the EPA's flexible permit system last week, Team Perry seemingly scored another victory for its friends with Tuesday's ruling against the cross-state pollution rule.
Written by the Obama Administration to replace a similar Bush Administration rule that also got struck down by the courts (but is now back in at least partial effect…it hurts to think about this sometimes), the cross-state pollution rule was an attempt to federalize the problem of continental air pollution, much of it caused by big ol' dirty coal plants like the ones in East and Central Texas.
Texas can't regulate the coal plant pollution that wafts in from Illinois or Kentucky. Likewise, New York can't regulate Ohio facilities that send air pollution over its state lines. A federal solution covering all 50 states is required. Tuesday's ruling agreed, but concluded EPA hadn't given Texas and other states more time to come up with their own strategies to cut air pollution from coal plants. Maybe EPA was influenced by the fact that at the same time this strategy was being proposed, Governor Perry was rolling out plans to help streamline the permitting of 17 new coal plants in Texas.
Neither one of these rulings is as dreadful as it might seem at first. Both can be appealed. And both have mitigating circumstances that cushion the blow. With the flex permit case, all the facilities in Texas got standard operating permits eventually, making the ruling on the flex program itself moot. With the cross-state pollution rules, the Obama EPA itself said that two-thirds of all the health benefits from the rules had already been achieved with the partial implementation of the Bush rules they were meant to replace.
However, the cross state rules were not only supposed to be good in their own right, they also are the underpinning for a couple of other national pollution initiatives, including helping communities meet the new Ozone standard of 75 parts per billion, and the new, lower Particulate Matter pollution standard. Without the rules, these standards will be harder to achieve. And guess who's own plans begin to get mucked up by that failure? You guessed it, the state of Texas.
Because in the case of DFW's chronic smog problem, the Texas Commission on Environmental Quality had already factored compliance with the rule into its already obsolete 2012 clean air plan for the Metromess. That was one of the reasons we were going to see the lowest ozone levels ever recorded in DFW this summer. Without that backstop, it's going to be hard not only to just meet the old 1997 ozone standard of 85 ppb – something DFW has yet to do despite two official tries now over the last seven years – it's going to be hard to meet the much lower standard of 75 ppb.
If you've seen the TCEQ propaganda of the last couple of years, it touts how much pollution totals in Texas have decreased. The Commission uses these numbers to then promote the Perry Team philosophy of limited government intervention, suggesting that it's the TCEQ and Perry responsible for those declines. They are not. For the most part, what the state is touting are the results of federal programs that have decreased pollution systematically across the country – everything from new fuel and pollution standards for cars and trucks, to new federal standards for specific industries, like refineries and chemical plants. Throw in the things that federal citizen suits and pressure got done despite TCEQ – think cement plant pollution reduction in DFW for example – and you have most, if not all of the things reducing pollution in Texas that TCEQ is claiming credit for.
Without the cross state pollution rules, the oldest and dirtiest coal plants in Texas will continue to operate for the foreseeable future. And when the wind blows, some of their pollution will be breathed-in by DFW residents. In the short term, this is Team Perry's trophy for all you hard-working Texas residents – more crap in your lungs.
If the state keeps clearing away all the federal programs that have actually reduced pollution over the last 20-30 years, those total pollution numbers won't be going down much longer. They'll be holding even and then going up. Left to their own devices, Team Perry would have us living in a polluter's Pottersville. And then who will the Governor blame?
Wise County in, Hood Left Out: EPA Declares New Non-Attainment Area for Smog in North Texas
At around closing time came news that the EPA had finalized the boundaries of the new “non-attainment area” for smog in North Texas that corresponds to enforcement of the “new” 75 ppb ozone standard approved last year. The 9 counties that were already in violation of the older standard are still there: Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant. The only new addition is Wise County, but it’s a huge one given its prodigious amount of gas industry pollution and commuter traffic to Tarrant and Denton Counties. It also means that Wise County will be getting an ozone monitor. If it’s placed correctly by TCEQ – and that’s a big if – it could be giving us a much truer understanding of how high or low ozone levels are really going. Since predominant winds during “ozone season” (April -November) are from the southeast to northwest, much of DFW’s dirty air gets pushed into Wise County, where it then officially falls off the map because there’s no air monitors there to record it. TCEQ likes it that way because ozone readings in Wise – where DFW dirty air meets gas patch emissions – could be significantly higher than in most of the rest of DFW. And that would dampen the Austin happy talk about improving DFW air quality. Also coming to Wise are things like those Vapor Recovery units on gasoline pumps, and other stricter pollution control requirements – although the impact on the entrenched gas industry infrastructure already there is unclear. Hood County was also singled out by EPA for inclusion in the non-attainment area but is left off this final order. It also has a number of gas industry facilities, including compressor stations, although most have shown up over the last ten years as opposed to Wise, which has seen decades of oil and gas production. There was no explanation for Hood exclusion in EPA’s letter. DFW wil be classified as a “Moderate” non-attainment area under the new standard while Houston will get a more severe “Marginal” classification. Why? Because the EPA uses a formula based on percentage above the new standard and Houston has traditionally had higher readings – think Ship Channel “upsets” and belches, even if DFW had just as many. Dallas and Houston remain Texas’ only non-attainmenta areas for smog, although that could certainly change over time. Next up is EPA’s determination of the compliance timeline for all non-attainment areas. The good news is that DFW’s deadline should be sooner than Houston’s because it’s not as severely ranked. The worse the air, the more time a region has to clean it up. The bad news is that it could still mean officials don’t have to get serious about cleaner air until around 2015 for a 2017-18 deadline. That”s been the pattern up to now – keep waiting until the last minute to think about how to dig yourself out of a multi-decade deep hole. And believe us, with this process, 2 years is “the last minute.” There could be all kinds of useful planning and researching going on right now but they’ll be none of that. Because insuring receipt of federal highway dollars, not protecting public health, has been the primary motivating factor behind the clean air machinery in North Texas. Until those priorities are reversed and clean air is sought for its own worth, we’re likely to always be behind the curve, chasing “unattainable” smog standards.
