End of an Era: TXI Cement Sold To Martin-Marietta
In a $2 billion deal, Raleigh, North Carolina-based aggregate and crushed stone manufacturer Martin Marietta Materials (a separate spin-off on the more well-know aerospace conglomerate) bought Dallas' own TXI Cement, which opened its first cement kiln in Midlothian in 1960.
This year, that kiln, along with the three other obsolete wet kilns at TXI's Midltohian plant that burned hazardous waste for two decades, is due to be demolished, following the company's corporate demise at the hands of the grandson of its founder. And then, the last remnants of the old TXI will be gone for good.
What does the change in ownership mean for breathers in North Texas?
Martin Marietta has owned and operated cement plants around the US in the past, but they'd divested themselves of these prior to 2014. As of now, the TXI cement plants in Texas and California are apparently the only ones the company owns. There's some speculation that Martin-Marietta bought TXI for its aggregate, stone, and concrete facilities in Texas and California, and will soon seek a buyer for the cement plants it inherited, but doesn't really want.
If that's true, the new owners will act as placeholders of the status quo, not investing in big new capital projects, but also trying not to lose any of the value of the assets they now have by running them into the ground. Martin probably won't look favorably upon attempts to bring smog-reducing modern Selective Catalytic Reduction (SCR) technology to TXI via the next clean air plant for DFW, now due in June of 2015. Not only would the plant be among the first to adopt the technology in the US, (even though SCR has been successfully used in European cement kilns for over a decade now), but it would mean new capital investment and a new learning curve.
Swiss-based Holcim Cement, with a huge plant already in Midlothian and a large manufacturing footprint in the US, was rumored to be one of TXI's suitors before the sale was announced. It could be that Holcim, or another well-established player in the cement industry winds up with the actual kilns in the next year. That could complicate the plant's participation in the new clean air in other ways even if new owners are not as intimidated by the demand for new technology
Politically, it'll be interesting to see which Austin lawyers and lobbyists get the business of the new company. Martin-Marietta owns over 40 facilities in Texas already and is represented by it's own crew. Will TXI's law firm and lobbyists survive the buy-out? There are industry lobbyists that will keep the ball rolling no matter what – the Chemical Council, the Aggregate Association, etc. But in Austin, it's all about relationships, and it's hard to say yet how this Martin's buying of TXI changes any of them.
Maybe the place TXI's absence will be felt the most in in the corridors of power in DFW. TXI was proudly headquartered in Dallas. Ralph Rogers, TXI's founder and patriarch was a driving force in local philanthropy, giving millions to public broadcasting (KERA is housed is housed in the "Ralph Rogers Communications Center") and other non-profits. Besides feeing like he was entitled to use PBS's iconic Big Bird to sell the benefits of burning hazardous waste in 50-year-old cement kilns, the non-profit giving Rogers was responsible for made him a known figure on the Dallas Charitable circuit. In turn, this made it hard for the Powers That Be to criticize Roger's company when it became a waste incinerator.
Locally, the establishment played golf with the Rogers' or attended black tie dinners with them, or helped them lift the oversized scissors at ribbon-cutting ceremonies. But that was old Dallas. Hardly of those relationships survived past Ralph Rogers' death in 1997. His son, Robert, failed to maintain that same high-profile locally, and his grandson Jamie seems totally disinterested in the family business or its legacy of charitable giving.
Now, the move of company headquarters from Dallas to Raleigh will complete the disappearance of the once-mighty TXI on the local scene. They'll still be company representatives at functions, but it won't be the guy who can write the big checks, or who the Mayor had a splendid time with last Saturday at the Club.
The company's local political influence has forever been diminished, and that's a good thing for citizens who are fighting the company to get modern controls like SCR. Now, it's just one more corporate entity with a presence in North Texas. A presence that makes it the single largest air polluter in the region. That's the way Dallas and other downwind cities should have viewed the company all along.
Physicians for Social Responsibility Talk This Thursday Night
Chris Masey
DFW has a lot of things, but one thing we do not have is a group of medical professionals who speak out for environmental health when it's threatened by pollution or other human-made disasters. Nationally, the group Physicians for Social Responsibility (PRS) has filled this role for over 50 years now. Founded in 1961 to make the medical case against a "winnable" nuclear war, the organization has morphed into a strong voice for clean air and water from a public health point of view.
Despite being a national center of medical research and care, DFW doesn't have a local chapter of PSR. But this Thursday, Chris Masey, the Austin-based Texas Director of the group will be in Dallas to talk about their connection to current energy and environmental fights, including the one against aging East Texas coal plants that were the subject of a Dallas County Medical Society petition to the Texas Commission on Environmental Quality.
His visit is sponsored by Dallas Interfaith Power and Light. Its scheduled for this Thursday beginning at 7 at the White Rock Methodist Church on Oldgate Lane. Here's what their blurb says about the talk:
Chris will speak about air quality as a crucial key to human health including fossil fuels background and information, specific toxic emissions, air as a carcinogen, climate disruption, and the shifting patterns of infectious diseases. Chris’s lecture will also include information about Texas PSR, and ongoing advocacy efforts to phase out and close coal-fired power plants and to advocate for stricter carbon emission standards.
More about our speakers: Chris Masey, MBA, is a eighteen-year environmental professional who has worked on a diverse set of projects throughout Texas focusing on public health, conservation, land stewardship, alternative energy sources, recycling, and environmental and solid waste planning. During the last two years, Chris has proudly helped guide Texas PSR (formerly Austin PSR) to become the largest environmental advocacy group led by healthcare professionals in Texas! Chris’ dedication to environmental sustainability is grounded in his love of Texas and the desire for his family to continue to enjoy clean air, clear water, and wide-open spaces.
If you're a medical professional who's interested in helping out citizens in need, or you know someone who fits thst description, please consider attending this Thursday's meeting. There's really no excuse for a metropolitan area the size of DFW not to have a cadre of concerned doctors and nurses who can speak put against fracking close to homes or burning plastic in cement kilns, or just confirm for some of our more aggressively ignorant elected officials that indeed, smog and lead are bad for people. With any luck, perhaps Chris Masey's appearance here this week can begin a conversation that leads to such an effort. It is way overdue. See you there.
Better Living Avoiding This Chemistry: An Industrial Toxic Primer
Even though this EcoNews article is about air poisons that result from fossil fuel production, it applies to just about any combustion source, including cement plants, manufacturing plants, vehicles, and so on. It's a pretty good top ten list, although you wonder why Dioxins and Furans got left off, since they're toxic by the gram instead of pound. Also missing is Particulate Matter as a stand alone threat, although it gets a shout out as a by-product. Nevertheless, these are the among the most dangerous pollutants that have caused and are still causing a lot of problems in North Texas and elsewhere:
1. Benzene
Benzene is a well-established carcinogen with specific links to leukemia as well as breast and urinary tract cancers. Exposure to benzene reduces red and white blood cell production in bone marrow; decreases auto-immune cell function (T-cell and B-cells); and has been linked to sperm-head abnormalities and generalized chromosome aberrations.
Benzene is one of the largest-volume petrochemical solvents used in the fossil fuel industry. It is a major component in all major fossil fuel production: oil, coal and gas. People are exposed to it from inhaling automobile exhaust and gasoline fumes, industrial burning such as oil and coal combustion, and exposure to fracking fluids.
There's a recent Emory University study concluding that risk for leukemia fell with every mile between a person's home and facilities that release benzene.
2. & 3. Sulfur Dioxide (SO2) and Nitrogen Oxides (NOx)
Sulfur dioxide (SO2) and nitrogen oxides (NOx) are two primary examples of particle-forming air pollutants (particulate matter). Particulate matter is known to contribute to serious health problems, including lung cancer and other cardiopulmonary mortality. SO2 and NOx are both highly toxic to human health, and contribute directly to thousands of hospitalizations, heart attacks and deaths annually.
SO2 is particularly dangerous for children. Studies correlate SO2 emissions from petroleum refineries—even in lower exposure levels over time —to higher rates of childhood asthma in children who live or attend school in proximity to those refineries. Similarly, small particles of NOx can penetrate deeply into sensitive lung tissue and damage it, causing premature death in extreme cases. Inhalation of such particles is associated with emphysema and bronchitis.
4. Petroleum Coke (Pet Coke)
Pet coke is a by-product of oil processing that's also used as a fuel. It's a heavy dust which resembles coal. It's burned in power plants and cement plants. It contains dozens of dangerous chemicals and heavy metals, including chromium, vanadium, sulfur and selenium. It's a huge contributor to particulate mater and NOx and SOx formation
5. Formaldehyde
Formaldehyde is a carcinogen with known links to leukemia and rare nasopharyngeall cancers, according to the International Agency for Research on Cancer. Formaldehyde is highly toxic regardless of method of intake. It is a potent allergen and genotoxin. Studies have linked spontaneous abortions, congenital malformations, low birth weights, infertility and endometriosis to formaldehyde exposure. Epidemiological studies link exposure to formaldehyde to DNA alteration. It is also contributes to ground-level ozone.
Independent studies, have detected dangerous levels of formaldehyde in both wastewater and ambient air emissions from fracking operations. One researcher, with the Houston Advanced Research Center, said reading from one test site in North Texas, “astoundingly high,” and, “I’ve never heard of ambient (formaldehyde) concentrations that high… except in Brazil.”
6. Polycyclic Aromatic Hydrocarbons (PAHs)
In actuality, this is not a single listing—polycyclic aromatic hydrocarbons (PAH) is an entire class of toxic chemicals, linked together by their unique chemical structure and reactive properties.
Many PAHs are known human carcinogens and genetic mutagens. In addition, there are particular prenatal health risks: prenatal exposure to PAHs is linked to childhood asthma, low birth weight, adverse birth outcomes including heart malformations and DNA damage.
Additionally, recent studies link exposure to childhood behavior disorders; researchers from Columbia University, in a 2012 Columbia University study, found a strong link between prenatal PAH exposure and early childhood depression. Infants found to have elevated PAH levels in their umbilical cord blood were 46% more likely to eventually score highly on the anxiety/depression scale than those with low PAH levels in cord blood. The study was published in the journal Environmental Health Perspectives.
7. Mercury
Mercury is a dangerous neurotoxin emitted from coal-fired power plants and any other combustion source using coal for fuel – like the Midlothian cement plants. It damages the brain and the nervous system either through inhalation, ingestion or contact with the skin. It is particularly dangerous to pregnant women and children. It is known to disrupt the development of the in-vitro brain. In low doses, mercury may affect a child’s development, delaying walking and talking, shortening attention span, and causing learning disabilities. High dose prenatal and infant exposures to mercury can cause mental retardation, cerebral palsy, deafness and blindness. In adults, mercury poisoning can adversely affect fertility and blood pressure regulation and can cause memory loss, tremors, vision loss and numbness of the fingers and toes.
One out of every six women of childbearing age in the U.S. have blood mercury levels that could be harmful to a fetus, according to EPA reports. The EPA estimates that 300,000 children are born each year at risk for significant development disorders due to mercury exposure.
8. Silica (Silicon Dust/Sand)
Crystalline silica (“frac sand”) is a known human carcinogen; breathing silica dust can lead to silicosis, a form of lung disease with no cure. This is a hazard in the cement industry and threat to those living downwind of cement plants, and now it appears to be one for natural gas roughnecks and adjacent homeowners as well.
Silica is commonly used, in huge amounts, during fracking operations. Each stage of the process requires hundreds of thousands of pounds of silica quartz–containing sand. Millions of pounds may be used for a single well.
The presence of silica in fracking operations, simply put, is a major safety risk with a high likelihood of dangerous exposure. Case in point: researchers from the National Institutes of Occupational Safety and Health (NIOSH) recently collected air samples at 11 fracking sites in five different “fracking states” (CO, ND, PA, TX and AR) to evaluate worker exposure to silica. Every single site had measures higher than the NIOSH threshold for safe exposure—so high, in fact, that about one-third of the samples collected were even above the safe threshold for wearing a safety respirator mask. This was reported in May 2013 in the Journal of Occupational and Environmental Hygiene.
9. Radon
Radon is a colorless, odorless, tasteless radioactive gas which causes lung cancer. It is the second largest cause of lung cancer in the U.S. after cigarette smoking. About 20,000 people per year die from lung cancer attributed to radon exposure according to the National Cancer Institute. Further, there is no known threshold below which radon exposures carries no risk.
Radon exposure can come from a variety of natural sources. However, fracking (natural gas) represents a significant new and increased source of radon exposure to millions of citizens. Radon is released into local groundwater and air during fracking operations. It also travels through pipelines to the point of use—be it a power plant or a home kitchen.
The science behind radon release and exposure is complex but explained well here by Christopher Busby, the Scientific Secretary of the European Committee on Radiation Risk, who warns that radon dangers from fracking “have not been addressed properly (or at all) by the environmental impact statements published by the operators, or by the Environmental Protection Agency in the USA.”
10. Hydrofluoric Acid (HF) / Hydrogen Fluoride
Hydrofluoric acid (HF) is “one of the most dangerous acids known.” HF can immediately damage lungs, leading to chronic lung disease; contact on skin penetrates to deep tissue, including bone, where it alters cellular structure. HF can be fatal if inhaled, swallowed, or absorbed through skin.
The senior laboratory safety coordinator at the University of Tennessee said, “Hydrofluoric Acid is an acid like no other. It is so potent that contact with it may not even be noticed until long after serious damage has been done.”
Hydrofluoric Acid is a common ingredient used in oil and gas extraction.
Numerous studies, including recent ones conducted by both The Center for Public Integrity (CPI) and the United Steelworkers Union (USU) cite the oil industry’s abysmal safety record as a high risk factor for a major HF accident; over the past decade, more than 7,600 accidental chemical releases from refineries have been reported by the industry. In the past three years alone, a total of 131 “minor” accidents involved HF.
State Predicts DFW Will Fail New Smog Standard, But Air Quality Is Getting Better!
By 2018 the Texas Commission on Environmental Quality predicts DFW will finally be in compliance with the federal ozone standard. The 1987 federal ozone standard. The 2012 ozone standard? Not so much.
That was the bottom line of last Tuesday's very defensive TCEQ staff presentation on the new effort to rein-in North Texas smog at the Council of Government's headquarters in Arlington, in what could be considered the kick-off meeting of yet another "State Implementation Plan," or SIP, for DFW. A plan drawn up by the state has to be submitted in place by June of 2015, with a goal of meeting the new 75 parts per billion ozone standard by the summer of 2018.
But even giving generous credit for the effect of new, lower sulfur gasoline standards, the TCEQ's computer model predicts the area will fall short of the 75 ppb goal at four very familiar monitor sites, with final estimates just a fraction above 75 ppb at Keller, readings of 76 ppb at Grapevine and Eagle Mountain Lake and as high as 77 ppb in Denton. To understand how optimistic even this result is however, you have to know that the Denton monitor is sitting at an average of 87 ppb as of this last summer. It took 10 years for that monitor to come down from an average of 97 ppb of ozone in 2003 to 87 ppb in 2013. With its new model, TCEQ is asking everyone to believe that ozone levels will come down another 10 ppb in less than five years.
As this excellent Denton Record Chronicle piece about the TCEQ effort points out, there's plenty of reasons to be skeptical. The agency has been wildly inaccurate in its past predictions. According to the last computer model the TCEQ ran, DFW was supposed to be enjoying record low ozone levels by now. It never happened, and in fact we're still in violation of the old 1987 standard of 85 ppb.
It's this lack of progress, particularly in the last thee years, that Downwinders and others cite when we're making the argument that more aggressive control measures are needed. In countering us, the state keeps insisting that – compared to 2003 – we're doing much better. And that's true -if you stretch things out over a decade we have gotten better. But compared to 2009 and 2010, we're doing the same or even worse. Look at the last three years of results and there's no way to conclude that DFW air quality is "getting better." It's just not true.
And all of this is really just a proxy for the fight over how much natural gas pollution is to blame for that stagnation. If there's no stagnation, there can be no cause of that stagnation. If there's a rollback in air quality, there must be a cause for the rollback. And many of us think that it just might be the pervasiveness of gas productions facilities within and surrounding DFW that are contributing factors.
Chris Kite, the TCEQ computer modeler that produced the new plan, used his presentation to mostly try to rebut specific quotes and arguments cited by Downwinders Director Jim Schermbeck about the lack of local air quality progress. It was a rare and raw indication of just how much TCEQ's Austin Headquarters considers Downwinders a threat. Too bad that even his own charts betrayed Mr. Kite's counter-thesis.
For instance, look at the numbers from 2008 to 2012 for average smog levels in DFW and see if you can cite the progress in this slide from the TCEQ PowerPoint:
For the past two years, our average has been higher than the two years before that. That ain't progress. Especially if you look at the previous four years, 2006 to 2009:
We're trying to think of what might have happened since 2008 to make it more difficult for the DFW region to attain a 1987 ozone standard at a time when emissions from just about every traditional source of smog pollution have been going down. Oh yeah, there was a huge natural gas field that opened up in the heart of the western part of the Metromess. But don't try telling the TCEQ that. They're convinced, absolutely convinced, that gas industry pollution couldn't possibly be responsible for any lack of progress in DFW air quality. Because hey, there hasn't been any lack of progress, and even if there wasn't, it wouldn't be due to the thousands of new gas sources. They're as sure of this as they are about their new computer model. Which is why the rest of us should keep an open mind.
TCEQ is hoping that coming close is good enough for EPA, that they can take advantage of something called "weight of evidence" that says that a clean air plan's parts are larger than its actual numerical sum and EPA reasonably expects the thing to succeed despite not all monitors hitting 74 ppb or below by 2018. In this way, Austin once again hopes to avoid any discussion about new control measures. But that's hanging your hat on a very precarious hook, given the agency's poor prognostication, and the EPA may demand a larger margin of safety.
In fact, an honest review of TCEQ's track record for past DFW clean air plans would necessarily place the "weight of evidence" in this new one on the agency itself to show that they'll get at least 10 ppb or more below the 75 standard just to make sure they come close to achieving compliance.
Something Wicked This Way Blows…..
Events like the gas pipeline explosion in Milford are graphic reminders of just how vulnerable our North Texas air shed is to pollution sources from Ellis County. Proximity, predominant wind patterns, and potential for disaster combine to make our Southern neighbor a constant threat.
On Thursday, one could see the plume of smoke stretch out south to north across the entire Metromess. It's a safe bet that not too many of the 6 million plus residents of greater DFW knew there was a town called Milford near them at the beginning of the day, but a lot of them had inhaled Milford soot by evening.
That would be the same soot that reporters keep reminding us "the EPA" says is "non-toxic," based on measurements. Except there is no such thing as non-toxic smoke from a combustion source, which the Milford explosion and fire most certainly was. All combustion produces soot, or Particulate Matter. According to the latest evidence from research scientists, there is no safe level of exposure to PM Pollution. That is, any amount of PM pollution can do human health damage. Even short-term exposure can lead to asthma attacks, heart attacks and strokes. How do we know this – the EPA tell us so on their own website.
Only a couple of years ago, the Magnablend fire in Waxahachie poured its own plume of "non-toxic" smoke into DFW skies, despite the incineration of a large variety of chemicals used in the oil and gas industry. You might remember the water run-off from fighting that fire went into a creek and killed a lot of fish. But don't worry, that same stuff in your lungs is nothing to worry about. Perfectly natural to be able to see what your breathing.
Perhaps the most spectacular modern reminder of how close Ellis County is to us in air miles came back in 1995 when a Midlothian-based tire dump, called…wait for it…."Safe Tire Disposal Company" that was actually a collection site for the nearby cement plant tire-burning operation caught fire its own self.
There are fires, and then there are tire fires. They burn extremely hot, produce a lot of that "non-toxic" smoke, and can keep going for days. And that's exactly what happened in Midlothian. The predominant southerly winds carried all that dark dense smoke right into Downtown Dallas, where it surrounded and engulfed whole office buildings.
Timing is everything and so it was with the Safe Tire Fire. It happened at the exact moment when local citizens were engaged in very public debate with state and local officials over whether air pollution from the three large cement plants in Midlothian (two of which were burning tires) could impact air quality in DFW. You read that correctly. In 1995, citizens were still trying to make the case that millions of pounds of air pollution released just across the Dallas and Tarrant County lines could possibly have a negative impact on metropolitan smog levels. And it was an uphill fight. Officially, there was no confirmation of the impact of these facilities. The DFW air plan stopped at the County Line. Unofficially, you could see the cement plant smokestacks as you drove I-20 across Grand Prairie and Arlington.
When those tires went up in smoke, so did the arguments being used to downplay the impact of Ellis County pollution. It was like adding a dark black dye to the North Texas air flow, beginning in Midlothian, and watching it be carried downstream/downwind right into the heart of downtown Dallas. It was the most defiant demonstration of the citizen's arguments one could imagine. After that, it was a lot easier for everyone to understand Midlothian was only a breeze away from their lungs.
With yet another fire in Ellis County setting off yet another dark, thick plume of smoke that wafts into DFW, we get a reminder of how much closer together the air brings us. Only about half an hour or so away from Milford, a little bit further south, is a new belt of natural gas compressors churning out voluminous amounts of air pollution that's being blown in the same direction as the smoke from that gas pipeline explosion. Unlike that smoke, pollution from these facilities will keep being released 24/7 for the foreseeable future. Add up all this new compressor pollution and it could rival the impact of a new coal plant – just upwind of us. Just because you can't see it doesn't mean it's not having an impact.
Once again, the state's position is that this pollution is no big deal. Once again, citizens are disagreeing. Who would you put your money on?
Can You Hear Me Now? EPA’s National “Listening Session” on New Coal Carbon Pollution Rules This Thursday
Many of you have already seen the increasingly urgent pleas from the usual suspects for people to show up at this Thursday's national EPA "Listening Session" on new emission standards for Greenhouse Gas pollution. Try to ignore the New Age-by-way-of-George-Orwell alternative name for a public hearing, and the industry-friendly "listening" schedule of 10 am to 3 pm, and concentrate on the fact this is one of only a handful of such sessions taking place nationwide, and it's in Texas, our Texas.
Like it or not, public health-minded residents of DFW have the burden of showing up to national hearings like this just to prove we exist. Nobody expects there to be an viable environmental movement in the Belly of the Beast, especially outside Austin. However hard we work to change that image, it's still a popular one and in this case, it hits entirely too close to home. Because Texas is the world capitol for carbon pollution. We're Numero Uno, A Number 1. We're living in the barrel of the gun that's pointed right at the planet's head.
EPA recently reported that Texas released more GHG pollution in 2012 than the next two states – Indiana and Pennsylvania – combined. We're responsible for a full 12.5 % of the entire US annual total, almost 400 million metric tons of the stuff, ever year. Just take a look at the difference between us and the other 49.
Then use this handy-dandy EPA map of incredibly large sources of GHG pollution in the US. It allows you to zoom down to what's in each county of each state. Look at all the sources around DFW. Most are also large sources of other kinds of pollution. We're living in a sea of pollution created by these facilities.
So when EPA decides to schedule its one and only listening session in Texas on new rules to reduce this kind of pollution from some of the biggest sources in our own backyard, we need to show up because we're a disproportionate part of the problem.
We also need to be there because industry will be there, in force. The old TXU really wants to keep its obsolete, lignite-burning East and Central Texas coal plants running without any of these modern pollution control contraptions. Doesn't matter if they're aimed at Particulate Matter, or smog-forming pollution or GHGs, they just don't want them. You can bet they'll be bringing in folks from those coal plants to say what a terrible economic cost it would impose on the host communities and the company, and how it'll put the entire statewide grid in peril.
Someone has to be there to balance that testimony by pointing out that the economic, public health, and environmental impacts of this pollution reach far beyond Limestone County, Texas or even the US, and need to be considered on the agency's balance sheet as well.
Every yahoo with Americans for Prosperity, or other industry astroturf groups will be there because these kinds of national forums to bash Obama's energy policies are what they live for – and it's the only thin they do halfway competently. Likewise for the industry-aligned Freedom Works branch of the Tea Party.
And does someone want to start an office pool on how many Republican primary candidates will be appearing, trying to outflank each other on their Right? Expect to see and hear a lot about "Obama's War Against Coal" on Thursday. It's Texas.
Which is why even if you're not a fan of this Administration, you have to recognize that the first attempt to regulate greenhouse gases from coal plants should be encouraged, in Texas. It's a foot in the door to do more effective things, to start talking about GHG regulations in a serious way. It establishes a precedent. And that is what industry fears the most. You don't have to like the EPA to understand that the enemy of your enemy is your friend in this fight. And did we mention it's in Texas?
Finally, we just emerged from an ozone season that was mild by recent standards – but still harsh enough to keep us in violation of the old 1997 smog standard. We know the East and Central Texas power plants contribute to DFW's air quality problems. These new carbon regulations EPA is considering for existing power plants have the potential to reduce a variety of air pollution, not just GHGs. We know Austin and TCEQ are going to be of no help in addressing these sources in the next DFW clean air plan. If reductions are going to happen, they're going to have to be driven by the EPA, local governments, or the marketplace. We can't let this opportunity for meaningful reductions and better air pass us by. If for no other reason, you need to show up on Thursday and say you support the EPA's regulation of these facilities because you've given up on Texas doing so.
For lots of reason, it's in your own self interest to attend this thing, even if you real passion is gas field pollution, or smog, or cement plants or whatever. A victory in this category of regulation is a victory for all of us involved in clean air issues. And it's Texas.
National EPA "listening session" on carbon limits for existing coal plants
THIS Thursday, November 7, 10:00 a.m. to 3:00 p.m.
1st Floor Auditorium, J. Erik Jonsson Dallas Central Library, 1515 Young Street, Dallas, TX (map)
2013 DFW Smog Report: Failure….Again
(Dallas)— On the eve of constructing yet another DFW clean air plan, the 2013 Ozone Season ended on Thursday the same way the previous 16 have ended: with North Texas out of compliance with the 1997 federal clean air standard.
Even a mild summer with lower temperatures and more rain couldn't save the numbers from exceeding an illegal three-year running average of 85 parts per billion at monitors in Keller and Grapevine.
According to Jim Schermbeck with the clean air group Downwinders at Risk, what makes this year’s violation particularly troublesome is that the 1997 standard has been replaced with a more protective one that's 10 ppb lower. “For the next DFW air plan to succeed, it will have to reduce smog to levels that no DFW monitors have ever recorded. I don’t know anyone outside of Austin who thinks the state is up to that task.”
That new plan has its official kick-off event next Tuesday, November 5th, beginning at 9am in Arlington at the Council of Governments Headquarters. It's the first briefing from the Texas Commission on Environmental Quality on the computer model it will be using to base the plan on. Everything about one of these plans is based on such a computer model, a model only the state can run. The plan must be submitted to EPA by June of 2015.
Even though extremely high ozone numbers were rarer this year, there were enough bad air days to cause the running averages of 10 out of 17 monitors, called "design values" to rise – not the kind of trend you want when you're next task is complying with a tougher standard.
Schermbeck was particularly concerned about a monitor near Mockingbird and I-35 in Central Dallas that’s seen its ozone average rise dramatically for three years in a row. “This is a monitor that had a "design value" of 67 parts per billion in 2010 – that is, it was in compliance with the new 75 ppb standard just three years ago. But now it’s up to 84 ppb and almost out of compliance with the 1997 standard. That's quite an increase in three years, and in a place where smog hasn’t been a problem for awhile.”
Every monitor inside the DFW metro area and even most "rural" monitors had a design value above the new standard of 75 ppb. Only Kaufman and Greenville made it under the wire, barely, with readings of 74 ppb.
As usual, the worst ozone levels were found in the northwest quadrant of the DFW area. This is a well-known historical pattern caused by the predominant southeast to northwest winds that blow pollution from the coast up through the coal and gas patches of East and Central Texas, over the Midlothian Industrial Complex and North Texas central urban cores into Northwest Tarrant Wise and Denton counties
This pattern has been the target of the last three state clean air plans, but has never been overcome. Schermbeck noted that last clean air plan to make a dent was the 2006 effort that produced lower numbers in steady fashion. Since 2008 however, air quality that was supposed to be getting better has gotten worse, or stagnated.
While cars have gotten cleaner during this time, and pollution from cement and coal plants has been reduced, there's one "source category" of pollution that's increased significantly since 2008: the gas industry.
In submitting the last DFW air plan to EPA in 2011, the Texas Commission on Environmental Quality estimated there were more tons of smog-forming Volatile Organic Compounds being released by the gas industry in the official DFW "non-attainment area" than by all the cars and trucks on the road combined. That wasn't true in 2008.
Moreover, this is new air pollution in a smog non-attainment area that doesn't have to be off-set by reductions in pollution elsewhere in DFW. Unlike every other large industry, the gas industry is exempt from this offset requirement of the Clean Air Act.
Denton's Airport monitor's 4th highest reading of 85 ppb this summer, the one that officially counts toward its running average, was the highest such reading in the entire state, including Houston.
There's no doubt Denton is in the middle of the local gas patch, as are the Keller and Grapevine monitors that had the highest design values this year. Given the decreases in pollution from other categories, are gas patch emissions keeping these numbers from coming down they way they were supposed to? Austin keeps saying no, but the evidence is compelling.
Just last year there was a study out of Houston showing how a single flare or compressor station could significantly impact local ozone levels by as much as 5 or 10 ppbs. TCEQ itself just produced a study this last summer showing how Eagle Ford Shale gas pollution is increasing ozone levels in San Antonio.
Local Barnett Shale gas pollution might explain these Tarrant and Denton county monitors' problems, but they don't explain the rise in numbers of the Dallas monitors, since the wind during ozone season comes in from the south to southeast.
What new pollution is coming from that direction? Gas industry pollution from numerous compressor stations and processing plants stations in Freestone, Anderson, Limestone and other counties just about 90 to 100 miles south-southeast of Dallas. If one adds up all the emissions these facilities are allowed under their "standard permits." it exceeds the pollution from coal plants like Big Brown. That's a huge hit from sources that weren't there 10 years ago.
In effect, DFW is getting squeezed between gas pollution being produced in the middle of its urban areas, and gas pollution blowing in from the south.
“Officials with Rick Perry's TCEQ would rather drink lye than admit gas pollution is causing smog problems for DFW” says Schermbeck, “but such an admission might be the only way to bring DFW into compliance with the Clean Air Act.”
“This is why local DFW municipal and county governments serious about air quality must divorce themselves from Austin's politicized science and begin to seek their own solutions. Austin really isn't interested in solving DFWs chronic smog problems. Heck, the Commissioners who run TCEQ don't even believe smog IS a health problem.”
Study Reveals Cancer Hot Spots Downwind of Canadian Oil and Gas Processing Centers
On the heels of the World Health Organization declaring air pollution a carcinogen, a study published this week from the University of California-Irvine and University of Michigan found higher levels of specific carcinogens in communities downwind of Canadian "oil, gas and tar sands processing zones", and higher rates of Luekemia and non-Hodgkin’s lymphoma among men living in those downwind communities.
Despite their rural location, the recorded levels of the carcinogens, including 1,3-butadiene and benzene, were higher than in some of the world's most polluted cities. Examining area health records that went back a decade showed the number of men with leukemia and non-Hodgkin’s lymphoma was greater in the communities closest to the pollution plumes.
The authors strongly recommended that the industrial emissions be decreased to protect both workers and nearby residents.
“Our study was designed to test what kinds of concentrations could be encountered on the ground during a random visit downwind of various facilities. We’re seeing elevated levels of carcinogens and other gases in the same area where we’re seeing excess cancers known to be caused by these chemicals,” said UC Irvine chemist Isobel Simpson, lead author of the paper in Atmospheric Environment. “Our main point is that it would be good to proactively lower these emissions of known carcinogens. You can study it and study it, but at some point you just have to say, ‘Let’s reduce it.’
Co-author Stuart Batterman, a University of Michigan professor of environmental health sciences, agreed: “These levels, found over a broad area, are clearly associated with industrial emissions. They also are evidence of major regulatory gaps in monitoring and controlling such emissions and in public health surveillance.”
Dr. Batterman is familiar to Downwinders old timers as being the first scientist to take on the state's laughable "Health Risk Assessment" of TXI's burning of hazardous waste at it Midlothian cement plant. In what became known simply as the "Batterman Report," his mid-1990's critique of the official document was devastating in its scope and depth. It became a template on how to deconstruct any TCEQ attempt to gloss over the dangers of living downwind of a large polluter.
In this new study, Dr. Batterman and his colleagues monitored emissions in the rural Fort Saskatchewan area downwind of major refineries, chemical manufacturers and tar sands processors owned by BP, Dow, Shell and other companies in the so-called “Industrial Heartland” of Alberta. Taking random one-minute samples in 2008, 2010 and 2012, the results were very similar over time – amounts of some of the most dangerous Volatile Organic Compounds were 6,000 times higher than normal. Higher than in Mexico City during the 1990s or in the still polluted Houston-Galveston area.
Simpson said the findings were important for other residential areas downwind of refineries and chemical manufacturers, including parts of Los Angeles.
“For any community downwind of heavy industrial activity, I would say it’s certainly prudent to conduct surveys of both air quality – especially carcinogens – and human health."
Cement Plants and Gas Plays Affecting Ozone Levels In….San Antonio?
For decades DFW was the only major urban area in Texas to have its air quality challenged by the cement industry. Repeated modeling over the course of the last several local air plans showed that the concentration of the plumes from three huge cement plants in Midlothian could increase downwind ozone levels significantly. Part of this is the voluminous emissions produced by the kilns and part of it's location, location, location – the close proximity of these cement plants to the center of DFW. So much so that you can see their smokestacks from I-20 in Grand Prairie and Arlington.
Then beginning in 2006 or so, the area's air shed began to be reshaped by the presence of gas production facilities as the Barnett Shale was opened up to exploitation from fracking, a process freshly exempted from just about every federal environmental regulation with passage of the 2005 Energy Act. But unlike large "stationary sources" like cement plants, these gas facilities were spread out over a large area, right in the middle of the Metromess, and were except from the "off-set" requirements of other large polluters. Even though their collective emissions were as large or larger than any other single industrial source, their decentralization allowed their operators to release their tons of pollution into the air without ever having to consider its impact on local smog levels.
That one-two punch of local industrial pollution flies in the face of the office park business image of DFW. Houston has traditionally been the city where industry has made it harder to breathe. In North Texas, it's supposed to be all about cars and trucks. But those cars and trucks lay a mostly uniform blanket of ozone over the entire area, whereas the gas production facilities and the cement plants are concentrated fire hoses of smog-forming pollution that can impact specific monitors over and over again.
And all of this has taken place during a time when the official federal ozone standard has been a relatively high 85 parts per billion. Beginning in 2015, the standard becomes 75 ppb, and it might drop to 65-70 by 2020.
Texas cities like Austin and San Antonio have had little problem complying with the higher standard, but now face obstacles to coming in under the wire of a 75 ppb rule.
For one thing, the only other large concentration of cement plants in Texas besides Midlothian is located along the I-35 corridor from Buda, south of Austin to North San Antonio. Because prevailing winds have often carried the pollution from these plants away from central Austin or San Antonio, they haven't been seen as much of a threat. But now urbanization is increasingly creeping westward into the downwind path of these plumes, adding some heft to the emissions and combining with them to elevate ozone levels.
And then there's the Eagle Ford Shale gas play, the new Wild West of fracking in Texas, taking place directly upwind of central San Antonio. Unlike the urban drilling in the Barnett Shale, most of the activity in the Eagle Ford is taking place in unincorporated parts of South Texas counties. There haven't been any reliable emissions inventory of the pollution coming out of he Eagle Ford, but it's considerable. Anecdotally, there seems to be a lot of flaring that DFW never saw. Because of the amount of production taking place, as well as its location upwind during the summer "Ozone Season," Central Texas is starting to sweat about its impact on its own air quality.
That concern has prompted a regional modeling exercise which is supposed to determine how much, if any, impact the drilling in the Eagle Ford is having on the Alamo City's air. Back in July, we reported that the preliminary numbers of this study showed that gas production was capable raising local ozone levels by as much as 3 to 7 parts per billion by 2018 – exactly when all Texas cities must be in compliance with the new 75 ppb standard.
Maybe 3-7 ppb doesn't seem like much. And it isn't, unless you're already at or above the new 75 ppb standard and that amount will put and keep you over that red line. Like San Antonio in 2013. The July headline in the San Antonio paper was unambiguous: "Eagle Ford drilling is polluting San Antonio's air"
But it looks like someone at the San Antonio Council of Governments is taking a page from DFW and TCEQ officials and downplaying those preliminary numbers from last summer.
Previous studies show that emissions of ozone-forming chemicals from sources other than drilling have dropped significantly since 2007 despite the city's population growth, said Steven Smeltzer, AACOG's environmental manager. Smeltzer attributes the improvement to new vehicle standards and voluntary reductions by local industries.
Preliminary numbers from the AACOG study also indicate that much of the problem lies in the Eagle Ford. InsideClimate News obtained a copy of the data, which have not been made public. The data show that during the months when San Antonio experiences the highest ozone levels—April through October—oil and gas development produced about half the amount of ozone-forming emissions per day as all other industrial sources combined.
Bella said the data came from an early version of the study that wasn't as thorough as later drafts. "My sense is they're really not worth using…They're not solid numbers."
He declined to comment on whether the numbers are close to the latest estimates. What matters isn't the number, he said, but the process behind the study. If the science isn't right, then it's "garbage in, garbage out."
Yeah, we know. Believe it or not, citizens had to literally force the TCEQ to consider the effect of the pollution from Midlothian cement plants before they discovered, wow, they really do have an impact. Likewise, it took Dr. Al Armendariz's 2009 study of Barnett Shale pollution for the state to even consider local gas sources might be a contributing factor to the DFW smog problem – although TCEQ officials are still doing their best to deny it. The largest purveyor of junk science in Texas is the Texas Commission on Environmental Quality. Remember that in 2012, TCEQ's computer model told us to expect the lowest level of smog ever recorded in DFW. Instead we got the highest levels recorded since 2008 or so. So yeah, GIGO.
That's why it's disappointing to see the Council of Government official try to use the same strategy with this new study – whose final edits will be made by TCEQ, not an independent entity. Just like with TCEQ's Wednesday's ruling against 7000 Dallas County doctors that said there's no link between smog and public health, Rick Perry's agency can't afford to admit the state's gas plays are making the state's air illegal and unsafe.
Like San Antonio, almost every other category of pollution in DFW has decreased over the last 6 years – except gas industry pollution. It's the one category of emissions that's grown and grown and grown – to the point where the state itself admitted that the industry was releasing more smog-forming Volatile Organic Compounds than all the trucks and cars on the road in North Texas. As DFW continues to linger in violation of an almost 20-year old obsolete ozone standard, it's the gas industry that is the logical culprit for the backsliding. It's the one variable that's going the opposite direction as all the others. But despite the overwhelming evidence to the contary TCEQ is busy defending the Shale from any charges that it has the least bit of impact on area smog, even to the point of ignoring basic air modeling chemistry.
San Antonio officials may want to deny the link between the Eagle Ford and smog in their city, may want to down play it, and they'll have plenty of rhetorical help from Austin. But when it comes to TCEQ rhetoric versus the real world, the monitors in the field tell the tale. Negligence doesn't make your air cleaner.
World Health Organization: Air Pollution Causes Lung Cancer
As of Thursday, the air you breathe CAN kill you, at least according to the World Health Organization, which officially classified air pollution as a cause of lung cancer. The move came after the group released a report earlier this year estimating that over 220,000 people died from lung cancer worldwide from exposure to bad air. Most of those deaths are occurring in countries in Asia.
Mostly these deaths are due to Particulate Matter pollution, the ubiquitous tiny particles of soot that are produced when things burn, like gas in cars, coal or gas or waste in power plants and cement kilns, and diesel engines and flares in the the gas fields.
Researchers have been producing one study after another for years linking a variety of illness and diseases to various ingredients of dirty air and specifically, Particulate Matter. Parkinson's Disease and other nerve and brain-related ailments, heart attacks and strokes, and of course respiratory problems have all been blamed on PM, but this is the first time it's been classified as a carcinogen. Most scientists in the field believe that there's really no level of exposure to the pollution that's completely "safe."
PM levels in DFW are generally low, but they've been rising over the last couple of years, and those measured levels are based on all of two monitors for all of the Metromess, so they could mask hot spots downwind of large sources (think Midlothian, compressors, and busy freeways). The EPA has proposed a new federal standard that's much lower than the current one, but it has yet to be implemented.
