Three DFW Ozone Monitors Have "Exceedences" of Old Standard to Officially Kick-Off Season

Thursday, May 17, 2012

Even though the federal government has established a new ozone standard of 75 parts per billion, DFW still hasn't managed to conquer the previous standard of 85 ppb. That was true again on Wednesday - the very same day the Dallas City Council began debate over a new gas drilling ordinance that could worsen regional air quality. Three ozone monitors - Dallas Executive Airport (the old Redbird), Dallas Hinton Street, and Arlington Municipal airport all registered 8 hour averages of 85 or above.  They were the first such "exceedences" of the standard this year. Arlington had at last three or so hours when it was breathing ozone levels of over 100 ppb. Whatever was happening today stuck around long enough to cause Parker County's monitor to still have readings in the 80's well past 10 at night. There were nine monitors that were at or above the new standard of 75 ppb spread out over four counties. Thursday is being forecast as another Orange Day for DFW, so in short order we could be halfway to an official violation (4 readings at the same monitor of 85 or more in one season) by the end of the week.  Read More

Homework for Tomorrow: KERA Dallas Fracking Debate; NPR on Health Effects, and Interview with Trinity East Manager

Tuesday, May 15, 2012

For your consideration on the eve of the beginning of the Dallas City Council efforts to rewrite the Dallas gas drilling ordinance: Your local NPR affiliate decided to return to being a Public Broadcasting station for an entire hour on Monday when KERA-FM held a little mini-debate in its studios between Council member Scott Griggs, the Ft. Worth League of Neighborhoods president Libby Willis, and industry rep David Biegler. Griggs had a good time with Biegler while Willis was the Ft. Worth Cassandra warning Dallas what it was about to step into. Please go check it out and encourage KERA to do more public affairs shows like this. Next comes a national NPR story on fracking that also ran on Monday and tells the story of downwind residents and their doctors in Pennsylvania who are attributing familiar illness and ailments to the introduction of fracking: "And all of a sudden your tongue gets this metal taste on it. And it feels like it's enlarging, and it just feels like you're not getting enough air in, because your throat gets real 'burn-y.' And the next thing I know, I ... passed out."  Finally, a fascinating Dallas Observer interview with a Manager of Trinity East Drilling who promises Dallas "billions" in gas reserve money and no harm to scary-looking parkland that's sitting in the useless floodplain anyway. Absorb all this and be prepared for a pop quiz tomorrow at 1 pm at 6ES at City  Hall when gas drilling Task Force Chair Lois Finkelman officially hands over her recommendations to the Council and debate begins. We're told this is just the first of what will be multiple briefings on the issue with a timeline for a vote happening before they Council goes on summer break around July 4th.   Read More

Texas Fracking "Disclosure" Law So Industry Friendly Industry Adopting It

Friday, May 11, 2012

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.   Read More

Study: Low Levels of Hydrogen Sulfide Linked to Asthma

Wednesday, May 09, 2012

You may not know the name of the chemical, but you know it by smell. "Rotten eggs" is the olfactory indication you're being exposed to Hydrogen Sulfide. There's a reason it smells like that. Biological sources can emit it. Certain bacteria produce hydrogen sulfide as they decompose waste - like rotten eggs. It also occurs in geothermal situations. Hot water, steam and magma from inside the Earth carry heat, minerals and gases – like Hydrogen Sulfide – to the surface, liberating them in springs, geysers and volcanic lava. If you've ever been to Yellowstone, you know the smell. Industrial sources of hydrogen sulfide include oil and gas drilling, refineries, paper mills, large scale livestock production, waste water treatment and landfills. At high levels of exposure, Hydrogen Sulfide is linked with serious neurologic damage – including death. Lower levels can trigger eye irritation, fatigue and headaches...and asthma according to a new three-year study out of Iceland. Measuring levels of Hydrogen Sulfide near major intersections and power plants in the capital city of Reykjavik that turn geothermal energy into electricity and heating steam, researchers found a weak but constant association between the pollutant and asthma medication rates. It's one of the first studies to find respiratory ailments at low levels of Hydrogen Sulfide - much like you'd find in the Barnett Shale or any gas or oil patch. The fact that oil drilling has been around for over a century, and yet only now are we actually studying what happens when people are exposed ti it at exposure levels found in real life, tells you all you need to know about the risks of allowing drilling so close to people.   Read More

Dallas Turns Over Trinity River and Parks to Drilling

Wednesday, May 09, 2012

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.   Read More

Community Meeting on Drilling in Dallas in Mountain Creek on Tuesday

Monday, May 07, 2012

Dallas Residents at Risk is taking its road show on fracking and the City's new gas drilling ordinance to southwest Dallas this Tuesday night,May 8th beginning at 7pm at the Harmony School, 8120 West Camp Wisdom Road. Along with northwest Dallas and West Dsllas, Mountain Creek is the site of some of the densest gas lease activity in the city. Longtime citizen activists Ed and Claudia Meyer will be hosting the event in their own neighborhood this time, with Downwinders Jim Schermbeck, Texas Campaign for the Environment's Zac Trahan, Sharon Wilson of Earthworks and the Blue Daze drilling blog, members of the gas drilling task force and other special guests. Don't forget that the Dallas City Council will be getting its first briefing on the gas drilling issue in a year on Wednesday, May 16th in the 6th floor Council Chambers at City Hall starting a 9am. If you can be there for this important milestone event, please attend and show your support for a stronger, more protective gas drilling ordinance for Dallas.   Read More

Scrubbing VOCs Out of the DFW Ozone Problem

Friday, May 04, 2012

Since DFW was first identified has having a smog problem in the mid to late 1980's, there's a standard formula that's become familiar to folks in local air quality: NOx and VOCs + Sunlight = Ozone. There have always been two primary culprits to North Texas' chronic smog problem. NOx, or Nitrogen Oxides which primarily come from combustion sources (engines, boilers, furnaces), and VOCs, or Volatile Organic Compounds that are mostly invisible plumes and fumes from things like gasoline pumps, storage tanks, as well as combustion. These pollutants combine with sunlight and heat that chemically interacts with them and forms ozone downwind. When the first air pollution control measures were adopted, Austin and the EPA agreed that VOCS were the driving force DFW ozone levels. Some old-timers may remember the Mrs. Baird's bakery on the West Freeway in Ft. Worth having to install controls that eliminated the smell of baking bread that was stout enough to waft across the highway. That's also why every gas pump in Collin, Denton, Dallas, and Tarrant Counties has a "Vapor Recovery Unit." Over the years, the blame shifted to a combination of VOCs and NOx, and that's what made it possible to bring large NOx polluters like cement plants and coal plants into the picture. Still, VOC emissions remained a major player in the DFW smog problem, and they've been addressed with controls on everything from solvents, to boat resins, to bakeries by every single clean air plan ever drafted by the state and EPA. But now Austin is saying VOCs aren't such a big problem after all, that DFW's smog is all about the NOx. Why? Austin's computer model says so. This is the same computer model that says DFW ozone levels will reach historic lows this summer. But might there be another reason? TCEQ's de-emphasis on VOCs coincides precisely with a very large jump in VOC pollution from the gas industry, a jump due to the explosion of drilling in the Barnett Shale and the government's lack of regulation to control it. In 2006, cars and trucks in DFW still spewed more VOCs than the gas industry. This year, the gas industry will release 30 MORE TONS PER DAY of VOCs than all the cars and trucks in DFW combined according to the TCEQ itself. But you'd never know it from looking at any of the public material the TCEQ produces about DFW's ozone problem. Instead it's all NOx all the time. This slant benefits a politicized TCEQ in a couple of ways. First, when you talk about NOx, you don't have to talk about the doubling of gas industry emissions over the past decade or so. Second, you can keep repeating the mantra that it's all about cars. Cars only produce about 15% of the VOC pollution in DFW vs 49% of all NOx in North Texas. No need to worry about new controls on cement plants or coal plants when it's really all about cars. Until today, that TCEQ message creep was showing up locally in websites and promotional material sponsored by the North Central Texas Council of Governments (NCTCOG) made up of area municipal and county governments. Unlike in past years when the familiar formula of both NOx and VOcs was recited to the public, this year NCTCOG's Air North Texas site, Air Facts page trumpeted that "On road vehicles cause half of the ozone forming emissions. Ozone forms when nitrogen oxides (NOx) combine with sunlight and intense heat." That just wasn't true. When you combine all VOC and NOx emissions (as calculated by TCEQ) in DFW, on-road vehicles account for 29% of ALL ozone forming emissions. Point Sources like cement plants and other industrial facilities, combined with oil and gas sources, total 25% - a much different looking pie chart than when you use NOx emission alone. To its credit, as a result of our inquiry, the NCTCOG Air North Texas "air facts" page has been re-edited to put VOCs back into the equation as of today, along with a little bit of spin claiming that "historical emphasis has indicated NOx reductions are the most appropriate way the region can lower ozone levels." We label that spin because it relies totally on the TCEQ's point of view, which has been, how do we put it, "historically wrong." We've already discussed how the DFW smog problem began as just a VOCs problem. We know they're still a factor. And if NOx reductions alone are so darn effective, why haven't they worked better? According to the TCEQ, total NOx pollution from ALL DFW sources decreased by almost 150 tons per day over the last six years. And yet 2011 was the worst ozone season since 2007. VOC Pollution? It's increased by 17 tons per day despite almost every individual category going down, save the ambiguous "Area" sources and emissions from the Oil and Gas industry. So if NOx decreases ozone so much more effectively than VOC decreases, how come 2011 ozone levels didn't reflect that? Many public officials around the country cite scientific evidence that already smoggy air turbocharges the ability of gas patch pollution to create more ozone. Usually very weak VOC molecules are transformed into smog-producing machines. TCEQ refuses to factor in this scientifically validated increased reactivity of VOCs being released by gas sources despite predominate winds carrying already smoggy air into the heart of drilling country in Tarrant, Denton, Wise, and Johnson Counties. It's model doesn't recognize this phenomena happening. TCEQ may also be underestimating the ability of these weak VOCs to already make ozone. In her 2011 landmark "Leaking Money" report for Downwinders, Dr. Melanie Sattler wrote that just the sheer volume of new gas industry VOCs is enough to affect DFW ozone levels. If DFW is ever going to solve its chronic smog problem, it has to have reliable information about what the increase in gas industry pollution is doing to our air. We don't have that now and no one in Austin is interested in finding out. Local leaders would be wise to decouple themselves from the TCEQ's politicized and uncurious approach to DFW air quality planning in Austin and find funding for their own research that can test for things the state doesn't want to know....Here's the full statement of Chris Klaus, Senior program Manager at NCTCOG and the lead staff person ther for all things air: "We appreciate your e-mail and comments regarding air quality facts and information on our Air North Texas and the North Central Texas Council of Governments’ (NCTCOG) websites.  We welcome and value this type of input.  In regards to your comments, historical emphasis has indicated NOx reductions are the most appropriate way the region can lower ozone levels.  Of the primary emission sources, on-road vehicle activities account for nearly half of the NOx inventory.  We frequently discuss NOx and VOCs when providing outreach, and have updated the Air North Texas website to make sure VOCs are referenced when appropriate.  Air North Texas is meant for the general public, and NCTCOG staff feels it is more effective to educate them about what they can do to improve air quality, and how to protect their health and the environment."  Read More

Endocrine Disruptors Make the NYT Opinion Page - Linked to Birth Defects in Midlothian

Thursday, May 03, 2012

In today's New York Times, columnist Nicolas Kristof writes extensively about the threat of endocrine disruptors - those chemicals that, instead of killing you outright, do strange and horrible things to your hormones and reproductive systems like genital deformities, breast cancer, infertility, diabetes and even obesity. Endocrine disruptors are everywhere, in food, cosmetics, even the receipts you get at the grocery store or your ATM machine...and the air pollution from many kinds of facilities.  It's the hormone-wrecking properties of one such chemical - bisphenol-A, or BPA, used to line food cans - that prompted eight medial organizations representing MDs in the fields of genetics, gynecology, and urology to say BPA should be banned from the marketplace last year. But it's clear that there are many, many chemicals, including less exotic ones like lead, and dioxin, that also act as hormone disruptors in the body. As Kristof explains, scientists know that even the tiniest variations in hormone levels influence fetal development. Endocrine disruptors play a kind of birth defect roulette as they course around the mother's body and end up in the fetus' bloodstream. In making his argument, Kristoff uses the example of a very specific birth defect, Hypospadias - a misplacement of the urethra - is now twice as common as it used to be and cites a leading researcher linking this trend to increased exposure to endocrine disruptors.  Why is this important for North Texans? Because the federal Agency for Toxic Substances and Disease Registry (ATSDR) found that the incidence of Hypospadias was approximately four times higher in Midlothian than the state of Texas as a whole. Remember, everyone is exposed to a constant sea of endocrine disruptors just from everyday living, so that wouldn't explain the much higher rate of a specific birth defect linked to the chemicals in Midlothian. But maybe operating three huge cement plants plus a steel mill could.  That same ATSR study - officially "inconclusive," also found a much higher rate for Microcephaly, where the newborn's head is more than two standard deviations smaller than the average, and Craniosynostosis, a condition in which one or more of the skulls' fibrous sutures prematurely fuses. That was only one study of a specific area. We know the Frisco lead smelter generates large quantities of dioxin. We don't know the impact of those releases. We know that gas drilling also involves a lot of chemicals identified a endocrine disruptors, but we don't how the last decade of urban drilling in the Barnett Shale has dispersed them or what their cumulative effect has been. According to Kristof, many scientists have seen enough proof and now want to better protect us from the dangers of endocrine disruptors. "For several well-studied endocrine disruptors, I think it's fair to say that we have enough data to conclude that these chemicals are not safe for human populations," according to Dr. Linda Vandenberg, who was the lead author of a new report we featured last month that concludes there are no safe doses for these kinds of chemicals. When it comes to the effects of chemical exposure, government regulations often lag far behind the science. How long will it take this warning to be implemented into public health precautions? And why don't we have a system that examines the possible impact to human health of a chemical BEFORE it's released into the marketplace?  Read More

More Details on the New DFW Smog Boundaries and Timeline

Thursday, May 03, 2012

First, if you haven't read our updated post below, please notice the correction to Tuesday's initial story. DFW's "Moderate" classification by EPA under the new 75 ppb ozone/smog standard is actually a more serious ranking than Houston's "Marginal" ranking. In fact, areas with Marginal status are expected to be able to achieve the standard without even having to submit a clean-up plan with special pollution control measures. That's right, for the first time in forever, Houston won't even have to submit a "SIP" - State implementation Plan - while DFW will have to write yet another one, the fourth one in 15 years. According to EPA's announcement, most metropolitan areas were classified as "Marginal," identifying North Texas right off the bat as one of the more seriously smoggy places in America (but still way behind parts of California with an "Extreme" label slapped on the LA basin, and "Severe" for three more separate areas.) Most of DFW's sunbelt peers have fared better than our metormess. Atlanta started out at the same place as DFW 15-20 years ago, but has cleaned up its act enough to rate a "Marginal" in this round. Phoenix is also "Marginal." But of course neither one of those has a major natural gas play in the middle of them. Second, the timeline for the next DFW's next smog plan is known. The clock begins ticking 60 days after the new designations are published in the Federal Register - sometime between July and September of this year. From that date, DFW leaders and the Texas Commission on Environmental Quality have exactly three years - until the summer of 2015 - to design and build a new clean air plan for DFW that will meet the 75 ppb standard. We have a three year running average of 90.6 ppb. Not to worry however. TCEQ has already told us that ozone levels will drop to historic new lows this summer thanks to so many new cars being bought. On the outside chance that doesn't happen, the Rick Perry- driven TCEQ will have to find some other nonsensical rationalization for avoiding new controls on the Governor's industrial contributors - cement plants, the gas industry, and power plants, like they did last year with the new car strategy. But don't look for Austin to even start working on this clean air plan until 2014. There's no rush because the agency doesn't believe the 75 ppb standard is even necessary. The Commission's leadership was vocal in its opposition against it.  If local leaders were smart, they'd disconnect their own clean air efforts from the state's and begin doing their own planning immediately, but traditionally they don't move until TCEQ says "jump". Add to this the new element of regional elected officials who, like Governor Perry, not only don't want to impose any new controls on industry, but don't even concede the value of cleaner air, and you already have a formula that's in danger of repeating last year's Worst Clean Air Plan Ever. 2015 isn't that far away, but without a serious overhaul of the regional air quality planning process, hope of meeting the new smog standard seems further than ever. By the way, counting our correction of the original story we ran on Tuesday, we've now published three posts on the new smog boundaries and deadlines. That's three more than any other source that we can find this morning.   Read More

Wise In, Hood Out: EPA Sets New Smog Boundaries for North Texas

Wednesday, May 02, 2012

(A previous edition of this post defined Houston's EPA rank of "Marginal" has being more sever than DFW's EPA rank of "Moderate." This was a mistake. In fact, it's just the opposite. "Moderate" is more severe under EPA's ranking than "Marginal." We regret the error. Thanks to a reader for pointing it out.)..........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 will be classified as a "Moderate" non-attainment area under the new standard while Houston will get a less severe "Marginal" classification. 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 worse the air, the more time a region has to clean it up. 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.  Read More
