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."

The EPA Loss in Court You Didn’t Hear About, But Could Affect You More in DFW
Let's face it, the EPA legal team has taken a bunch of hits lately. Losses in court over the Texas Flex permitting plan and national cross state pollution rules, among others, have gotten lots of headlines, but for various reasons may not be as awful as they first sound to environmentalists.
But there was a recent ruling that did hit home for metropolitan areas like DFW that are a) already in "non-attainment" of the federal ozone, or smog, standard, and, b) host lots of urban gas and oil drilling. You probably didn't hear about it, but it may have more of an impact on your air here because it once again left a large loophole in current law that allows the oil and gas sector to escape emissions "off-setting."
According to the Clean Air Act, every large industry that comes to set up shop in a non-attainment area like DFW must decrease as much pollution as it estimates it will increase. This is required so that new pollution doesn't just take the place of pollution that's been reduced from industries already operating in the area. Otherwise, there would be a large imbalance between new industries and established ones that would put air quality progress in peril.
And that's exactly what's happening in DFW.
For a decade now, gas mining in the Barnett Shale has added tons and tons of new air pollution to the North Texas airshed that has not had to be off-set with reductions. While emissions from this industrial sector grew, pollution from local cars, power plants and cement kilns actually decreased. Based on past experience DFW should be making headway toward cleaner air. But we're not. For the last two years, DFW air quality progress has stagnated and even begun rolling backwards. This year we already have five monitors out of compliance with a 1997 ozone standard, compared to just one in 2010.
So why aren't gas emissions subject to Clean Air Act "off-sets" just like a power plant or cement kiln? Because nobody writing the Clean Air Act in 1970, or its amendments in 1991, anticipated urban drilling on the scale we're experiencing it in DFW these days. Nobody foresaw the establishment of a huge gas patch in a large metropolitan area with connected, but widely diffused sources of emissions spread out over hundreds of square miles. They were thinking about "stationary sources" of pollution like coal-fired power plants, refineries and the like. The amounts needed to trigger off-setting are all oriented toward these massive facilities, not lots of smaller sources that eventually equal or surpass their output. As a result, there's a huge loophole that keeps the oil and gas industry from being regulated like any other industry in a non-attainment area.
EPA has recognized this loophole and tried to close it by ruling that facilities connected by process in the gas field may be treated as one large source of pollution – the term is "aggregate." And this is the definition that a court recently shot down in a Michigan case:
"The Cincinnati, Ohio-based 6th U.S. Circuit Court of Appeals held yesterday that EPA had no basis to find that the natural gas sweetening plant and sour gas production wells owned by Summit Petroleum Corp. in Rosebush, Mich., are "adjacent" under the statute and therefore a single source just because they shared some similar functions.
It is an important case for the oil and gas industry because it is the first appeals court ruling to address a recent EPA move seeking to more aggressively "aggregate" various nearby sources of air pollution at oil and gas facilities for permitting purposes.
The court ordered EPA on a 2-1 vote to consider again whether the facilities, spread over a 43-square-mile area, are "adjacent" under the "plain-meaning of the term," which focuses only on physical proximity."
Just in case there was any doubt about why the gas industry was challenging the EPA policy of aggregating, the next sentence of the article makes it clear:
"Industry groups object because it can bring the individual sources under the umbrella of more stringent Clean Air Act permitting requirements."
Now, of course adjacent in common law means next door. But what does it, or should it mean, in environmental law? The collective air pollution being generated by that 43 square mile complex could very well be "adjacent" to your lungs a short distance downwind. But the court didn't see it that way.
That means that going into the next clean air plan for DFW – one that will, at least theoretically be aimed at the new 75 parts per billion ozone standard – EPA will not be able to "off-set" the large amounts of air pollution generated by gas mining and processing in the North Texas non-attainment area.
And that's why we have to do it ourselves, one city and one county at a time. Starting in Dallas. Starting now.
As part of the larger re-writing of the Dallas gas drilling ordinance, a very large and impressive coalition of homeowners groups, neighborhood associations, and environmental organizations have all endorsed the idea of Dallas requiring local off-sets for any pollution released by new gas facilities within the city limits. A company would have to pay for projects that would reduce as much pollution as it was estimated to release every year. Dallas would be the first city in the country to adopt such a policy, but it probably wouldn't t be the last. And it wouldn't take that many before you started seeing an impact on industry's emissions.
We have a model in the successful Green Cement Campaign of the last half decade, that also started in the Dallas City Council chambers with a first-in-the-nation vote. All it took was a dozen cities and counties passing green cement procurement ordinances to get the cement industry's attention. As of 2014, something like 300,000 tons of air pollution a year will have been eliminated because there are no more dirty wet kilns in North Texas.
We can do it again. This time with gas patch pollution. We have to. Nobody else is going to do it for us.
Gas Industry Cites Decreasing CO2, Forgets About Increasing Methane
Maybe you've seen the headlines over the last couple of days. US Carbon Dioxide (CO2) emissions reached an historical 20 year low in the first quarter of 2012. The Federal Energy Administration attributed this decline to three factors: a mild winter, less travel, and gas-powered utility plants replacing coal-fired ones. Whereas coal was producing about 50% of America's electricity in 2005, it's only contributing 34% now, with most of that slack now being taken up by gas-generated electricity.
Gas industry representatives were quick to take credit for the reduction and use it has proof of how climate-friendly natural gas is. But they forgot something important when they did that. They didn't weigh the increase in methane releases caused by gas mining against the decrease in CO2 pollution. Methane doesn't have the lifespan of CO2 in the atmosphere, but pound per pound in the short-term, it's 25 times more potent in its climate change impact. According to climate scientist Michael Mann of the Earth System Science Center at Penn State University, “We may be reducing our CO2 emissions, but it is possible that we’re actually increasing the greenhouse gas problem with methane emissions.”
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?
Texas Fracking “Disclosure” Law So Industry Friendly Industry Adopting It
One of the reasons Dallas Residents at Risk has made full disclosure of fracking chemicals one of its five basic protections to be included in Big D's new gas drilling is because the Texas law passed last year by the legislature is so inadequate. Besides allowing for "trade secrets" that mean there's no real disclosure, the law doesn't even allow physicians or first-responders to know what's behind those trade secrets before they respond to an emergency situation involving them. Now we know that the law is so industry-friendly that Exxon and its gas drilling subsidiary XTO sponsored it as a nationwide model within the notorious American Legislative Exchange Council which received a lot of publicity over its controversial "Stand Your Ground" legislation
Dallas Turns Over Trinity River and Parks to Drilling
It's sure going to be crowded between the levees of the Trinity River in Dallas in a couple of years, what with the tollroads, and parks, and solar-powered water taxis. And they'll all have to dodge the new gas rigs, tanks, pipelines, separators, compressors and processing stations if gas operators get their way.
A new map direct from Dallas City Hall staff shows practically the entire Trinity River bottoms from extreme Northwest Dallas to Downtown leased to just one fracking company, Trinity East.
Look at a copy of the map accompanying this post. All that area in green with black stripes running through it has been leased for gas drilling purposes. Dallas Council member Scott Griggs asked city staff to start preparing maps of where all the city owned gas leases were located. This is the first. It was released to the press with the help of Dallas Residents at Risk, who produced their own map of gas leases on city land back in February (Channel 8 News coverage here; Channel 4 here).
In addition to the whole of the river bottoms, the map also shows two pieces of park land in Northwest Dallas leased for gas drilling – the Crown Point baseball and soccer field complex and the proposed Elm Fork Soccer Complex. And all this is in addition to the LB Houston Golf Course lease site where the city is considering drilling next ti the park's golf course.
This map is just the latest piece of evidence that Dallas hasn't really leaned anything from its past neglect and abuse of the Trinity River. When push comes to shove, it's still a dumping ground for the Powers That Be. To paraphrase the proponents only slightly, "It's already where we put landfills, so let's just keep putting crappy stuff by the River." Status Quo in 1964, even 1974 but unbelievable in 2012.
The final round in this two year old fight to write a new gas drilling ordinance for Dallas begins at 9 am on May 16th at Dallas City Hall in the City Council Chambers when the Mayor and Council will officially receive the gas drilling task force recommendations and discuss where to go from here. We know it's a workday, but we must show strong public support for the most protective regulations we can get. We must send a message that even the Dallas City Council can't ignore.
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.
“Drilling in Dallas” Community Meeting: Northwest Dallas on Thursday Night
Dallas Residents at Risk’s road show on fracking in Dallas continues its tour with a stop at 7pm Thursday night, May 3rd, at the North Hills Prep School at 606 E Royal (near L.B. Houston Golf Course and the now famous drilling pad-in-a-park endorsed by none other than the President of the Dallas Parks and Rec Board). If you’ve seen the map of gas drilling leases on city owned land, you know that Northwest Dallas is a hotspot of activity. Along with West Dallas and Mountain Creek, it’s one of the most densely leased areas of the city. Come see a basic explanation for why the activity is hazardous to neighborhoods, talk to some of the good guys who were on the City’s gas drilling task force and find out what’s being done to write a better gas drilling ordinance. Information is power. Don’t be powerless.
