From the LA Times: "The proportion of Americans with asthma increased from 7.3% in 2001 to 8.4% in 2010, marking the highest level ever, the U.S. Centers for Disease Control and Prevention said Tuesday. In 2010, an estimated 18.7 million adults and 7 million children had the disease -- one in every 12 Americans. Overall, about 29.1 million adults have been diagnosed with asthma at some point in their lives, but many of those were misdiagnosed or have apparently recovered, leading to the current figure of 18.7 million. Children (9.5%) had a higher asthma prevalence than adults (7.7%), suggesting that the disease will become a bigger problem in the future. Females (9.2%) had a higher prevalence than males (7%). People of multiple race had an incidence of 14.1%, while Asians had the lowest (5.2%). Blacks were at 11.2%, while whites were at 7.7%. Hispanics of Puerto Rican descent had the highest prevalence, 16.1%. Death rates were highest for women, blacks and people over the age of 65. In 2009, the most recent year for which data are available, asthma accounted for 3,388 deaths in the United States, 479,300 hospitalizations, 1.9 million ER visits and 8.9 million visits to physicians' offices, the CDC said. The estimated costs to society were $50.1 billion per year due to medical expenses, $3.8 billion resulting from missing work and school, and $2.1 billion from premature deaths."  Read More

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

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

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

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

(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

This annual effort was released this week and relies on data from 2008, 2009, and 2010. In other words, it does not include last summer's horrific ozone season, the worst in five years, and the one that had Dallas taking away the title of worst air in Texas from Houston. Even without those numbers, air quality in the DFW metromess is ranked 12th worst in the country out of 277 metro areas, while Houston is ranked 8th. It also gives a pass to DFW on particulate matter, despite seeing levels that have been associated with strokes. This is because the metrics the ALA uses rely on federal standards - as long as you're above those standards, it gives you a passing grade. But now science tells us that those standards are not protective, so take these kinds of assurances with appropriate grains of salt. Look at the year-by-year charts for DFW pollution. The good news is that both ozone and PM levels started to fall dramatically around 2006-7 - perhaps as a result of the last semi-competent air plan that was implemented during this timeframe. Change is possible. We can find ways to clean the air when we want to. The bad news is that since that plan was adopted and carried out, there's been no follow-up by the state, and no attempt to reign-in the air pollution from the gas industry, which has almost doubled in the last six to seven years. This is why ozone numbers climbed last year and it's also why many of us predict that this summer will see no relief from our chronic ozone pollution. Next year's State of the Air report will not be as kind.  Read More

Public outrage over cement plant pollution has sparked a government ultimatum that the industry must comply with new emission standards in three months or risk being shut down temporarily or permanently. This isn't happening n Western Europe. And because this isn't fiction, it's not the US either. No it's Dubai.  It's part of a larger effort to reduce polluiton from cement plants by 50% in three years  in that country, which is still experiencing a construction boom. Plus, how's this for nice touches, the plants also have to "ensure 50 per cent of the boundary of their factories be covered with trees and other foliage, to mitigate some of the carbon dioxide emissions and to 'improve the ecology' and appearance of the area." Meanwhile, we're hearing nasty rumors about the EPA possibly backing off its new cement plant emission rules that are due to be implemented in the fall of next year. Never thought we'd say it, but could we just be guaranteed the same kind of environmental protection as a Developing Country?   Read More

Titan Cement is trying to build a huge new cement plant near Cape Fear in North Carolina. People who live there are putting up quit a fight to prevent them from doing that. In order to get these people to settle down, Titan sued a couple of local residents, Kayne Darrell and pediatrician David Hill, who made comments at a County Commissioners' meeting that went like this: "...we know from numerous studies that if we build this thing, more children will get sick, a handful of them will die. We also know from the adult studies that more adults will get sick and quite a few more of them are going to die as well Which ones? Can't tell you. That makes it difficult, but there will be some." Quite right. We know all these things because numerous scientific studies show a very straight-forward relationship between the kinds of crud put out by cement plants and rates of asthma, heart attacks, strokes, etc. There is nothing the least slanderous or libelous about saying so. And yet Titan sued in hopes of intimidating not only the two citizens it sued, but everyone else who wanted to speak up but now would be afraid of getting sued. That's how SLAPP (Strategic Lawsuits Agains Public Participation) suits work. No one ever expects to win a case. If you're a company, you win just by filing because it shuts people up, or a least that's the intent. Well, today comes word that Titan and the citizens have "settled" the case and Titan now "recognizes that reasonable minds have the right to disagree, and respect both Dr. Hill and Ms. Darrell's right to do so." Isn't that precious? The Greek Multinational Cement Giant agrees that the quaint American First Amendment is still the law of the land here. In organizing, we often say it's all about relationships and the Titan press release onthe matter seems to bear this out. "Prior to today's mediation, we had not personally met and spoken with Dr. Hill and Ms. Darrell," Titan said in a statement. "Having done so, we do not believe that either Dr. Hill or Ms. Darrell intentionally made any false statements about Titan or our plant in New Hanover County." So you know, all it took was seeing that in fact these citizens were not horned devils for the company to change its mind. For his part, Dr. Hill would not comment on the resolution Wednesday except to say, "I look very much forward to being able to focus all my energy on my efforts to improve the health of children in this region." Both defendants will release a statement in the next 24 hours according to their attorney. Meanwhile, Titan won its state air permit, but its's still not a free and clear path to construction.   Read More
