Although on any given day there's a lot of competition, the Agency for Toxic Substances and Disease Registry might be the most irrelevant government bureaucracy going. Thursday it announced that the latest installment of its years-long "health consultation" of Midlothian will be the subject of yet another community meeting in that town on Thursday May 24th from 7 to 8:30 at the Midlothian Conference Center. The ATSDR evaluation started in 2005 at the request of Midlothian Citizens when TXI was still burning hazardous waste. It then was the subject of a 2010 Congressional investigation that revealed how the Agency mostly neglected to do any real science in the course of its evaluation. This new meeting concerns an analysis of air monitoring information that "will support public health evaluations for many of the pollutants of concern." Of that we have no doubt. Since ATSDR does no monitoring of its own, it's completely reliant on the monitoring done by theTexas Commission on Environmental Quality. Does anyone know of any instance where TCEQ monitoring has shown anything to be concerned about? If citizens complain about getting sick from industrial pollution, it's TCEQ position that it's the fault of anything but the pollution itself. No amount of empirical evidence collected by citizens in the field from their own sampling or experience can convince Austin otherwise. TXI quit burning waste in 2008. ASTDR's evaluation of Midlothian? It just might outlast the plant itself.   Read More

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

Here's a story from Florida about the Brooksville Cemex cement plant's new permit that displays the quintessential spin from the cement industry about their transformation into garbage burners. 1)The headline uses the preferred industry term of "alternative fuels" instead of garbage. 2) It leads with all the feel-good fuzzy bio-garbage like peanut shells and wood chips. Only further down do they let you see the rest of the list -  "including plastics, carpet, roofing materials and wood treated with creosote. Included, too, are so-called engineered fuels such as cleanup debris from natural disasters, processed municipal solid waste, dried and sanitized sewage bio-solids, noninfectious hospital materials, expired pharmaceuticals and confiscated narcotics." 3) It makes sure you know that this new garbage burning will shrink the plant's carbon footprint and lower emissions of toxic chemicals like Mercury - but the plant will not be amending its operating permit to reflect those proposed decreases. 4) for all the talk of "alternative fuels," the plant is mainly still burning coal and tires, both of which it's been burning for a long time. The largest expense of running a cement plant is fuel costs. The industry is always finding a way to cut those costs. In the 1980's and 90's it tried turning cement kilns into hazardous waste incinerators by getting paid by polluters to burn their crap for less money than the pros. That met with quite a bit of public resistance and new regulations that made it harder to keep doing that. So now the industry is pivoting toward a laundry list of  "non-hazardous" wastes - municipal garbage, sewage, medical waste, plastics, car interiors - garbage. Except that anyone who's ever studied the the history of American  garbage incineration - and there's quite a history - knows there's nothing non-hazardous about the practice. Just because a waste isn't classified by EPA as a "hazardous" waste coming in the front door doesn't mean it doesn't emit hazardous air pollution when it's burned or carted off as ash out the back door. And even thought there's a lot of boasting about emission decreases, the industry isn't backing up that talk with real cuts in their permits. Places like Midlothian, home of three huge cement plants, and a concentration of cement manufacturing unmatched anywhere else in the US, are looked upon as nothing but large "landfills in the sky" to both waste producers and the cement plant operators themselves. TXI's Midlothian plant, directly south and upwind of DFW, just received a new permit "amendment" last June that allows them to burn the same kind of  long list of garbage as the Florida kiln. They got this without any public notice or hearing or anything. None required as long as TXI promises, cross their heart, that the emissions won't increase above what they are now. And if they do? We won't even be able to know for sure until a test burn that will occur after they start burning garbage - they can wait up to a year to do the testing. This is why public participation is an over-arching issue in Texas now. Without it, there are no checks and balances. Only more experiments taking place in your lungs.   Read More

That's the conclusion of a new report that was three years in the making. Dr. Laura Vandenburg of Tufts University led 12 other scientists in an effort that examined hundreds of recent studies on the effects to people and animals of hormone-changing chemicals that are widely used in industry, including cosmetics, pesticides and plastics. They found that even tiny doses of these chemicals, called "endocrine disruptors," can cause harmful health effects such as infertility, cardiovascular disease, obesity, and cancer. Writing in a separate editorial about the report, Vandenburg stated that "After reviewing hundreds of studies, my colleagues and I have concluded that there truly are no safe doses for these hormone-altering chemicals. We found overwhelming evidence that these hormone-altering chemicals have effects at low levels, and that these effects are often completely different than effects at high levels. For example, a large amount of dioxin would kill you, but a very small dose, similar to what people are exposed to from eating contaminated foods, increases women’s risk of reproductive abnormalities." In North Texas, we're not only surrounded by endocrine disruptors in products we buy, but also in the air we breath. Lead from Exide's Frisco smelter is an endocrine disruptor. Many of the pollutants released by the Midlothian cement plants - TXI, Holcim and Ash Grove - are endocrine disruptors, as are a good percentage of the chemicals emitted by the gas industry when its fracking a well. Like so many other kinds of human-made pollutants, endocrine disrupters were allowed in commerce without full understanding of their possible public health effects. That's why the report also recommends that the way the government tests for a chemical's toxicity be modernized. Currently, there's no evaluation of health effects from endocrine disruptors at the low level of exposure encountered by most people. These chemicals actually can harm you more in smaller doses over a long period of time than really high short term exposures. It's called a "non-linear" response because it doesn't follow the old "the dose is the poison" rule that makes the amount of poison the driver of any possible toxic effects. “Current testing paradigms are missing important, sensitive endpoints” for human health, Vandenburg and Co. said.“The effects of low doses cannot be predicted by the effects observed at high doses. Thus, fundamental changes in chemical testing and safety determination are needed to protect human health.” In other words, we need a system that catches these chemicals before they're widely marketed in consumer products, or released as pollution into the environment; before we become unwitting lab rats.  Read More

(Dallas)----Kansas City-based Ash Grove Cement Company has submitted a permit amendment to the Texas Commission on Environmental Quality that seeks permission to convert its Midlothian plant from three wet process kilns operation to a single dry process kiln by 2014. In a cover letter to the TCEQ dated January 13^th, Trinity Consultants’ Kasi Dubbs writes that, “With this permit amendment application, Ash Grove is proposing to modify Permit Number 1 to decommission two kilns at the plant, and reconstruct that third kiln from a wet process kiln to a preheater, precalciner kiln system." According to the permit amendment application, total plant manufacturing capacity will decrease by 230, 000 tons a year, from a maximum of 1,182,000 tons of cement to 949,000 tons. Ash Grove claims that this decrease in capacity combined with cleaner dry process kiln technology will reduce pollution from its Midlothian operations by almost 105,000 tons of air pollution a year, including 98,000 tons of CO2, 6,000 tons of Sulfur Dioxide, and 560 tons of smog-forming Nitrogen Oxides. Ash Grove’s decision means that in two years, Texas will no longer host any obsolete wet cement kilns that were the industry standard throughout the 20^th Century but whose energy inefficiency and pollution made them disadvantageous in the 21^st. As recently as 2008, Midlothian had almost a fifth of the nation’s total wet kilns. Wet kilns depend on massive quantities of water to mix the ingredients of cement and then uses equally massive amounts of energy to evaporate the water out of the cement through exposure to extreme heat. They began to fall out of favor after the second Arab oil embargo of the 1980’s when energy prices climbed significantly. Their numbers have been steadily declining for decades. In 2010, TXI Cement announced they were closing their four wet kilns in Midlothian, almost a decade after operating side-by-side with its huge new dry “Kiln #5”. With Ash Grove’s conversion, there will be only a handful of wet kilns left in the entire U.S. Citizens who had spent years campaigning to close the Midlothian wet kilns were celebrating. “This is truly an end to an era. These kilns have been operating since 1965. They were the dirtiest cement kilns in Texas. They inspired a grassroots rebellion in DFW that forced Ash Grove to court. Their closure is one more step in bringing all of the Midlothian cement plants into the modern era,” said Jim Schermbeck, Director of Downwinders at Risk, the local clean air group founded almost 20 years ago to oppose the burning of hazardous waste in the Midlothian kilns. It was Downwinders who broke the story on January 4^th that Ash Grove was finally considering dry conversion in Midlothian, while also being the target of a national EPA enforcement action. The group encouraged it supporters to launch waves of e-mail blasts to both the company’s headquarters and EPA administrators urging Ash Grove to commit to dry conversion, while also seeking to include the switch as part of the agency’s list of demands in any national settlement. Nine days later, Ash Grove submitted its permit amendment to the TCEQ. Regulators admitted that the publicity probably accelerated the final corporate decision in Kansas City. In 2006, Downwinders successfully pushed for inclusion of a recommendation in that year’s DFW smog plan that urged local governments to buy cement exclusively from the state’s dry kilns to provide an incentive for wet kiln operators to modernize. Schermbeck and the group then began their “green cement campaign” that methodically collected agreements from city and county governments that cut Ash Grove off as a potential cement supplier for municipal and county projects. Dallas passed the nation’s first green cement policy in May of 2007 during the last days of Mayor Laura Miller’s term. Over the next two years, Ft. Worth, Arlington, Plano, Denton and the Dallas County School District passed green cement policies – all unanimously. When Tarrant County passed a green cement policy by a vote of 5-0 in November 2008 Ash Grove decided it couldn’t afford to lose any more customers and took the County and all the rest of the green cement cities to court. Last January, when it looked like Dallas and Arlington might be forced to give up their policies as part of a settlement with Ash Grove, Downwinders stepped in and was praised for reaching a compromise that saved the policies’ intent to force modernization, but removed the threat of Ash Grove legal action. Meanwhile, in the 2007 and 2009 state legislatures, green cement bills garnered a bi-partisan group of sponsors including former State Senator Kim Brimer, his successor, State Senator Wendy Davis, and Tarrant County State Representative Vickie Truett. Schermbeck noted that the green cement campaign had been of the few grassroots environmental success stories during the tenure of Governor Rick Perry. Ash Grove’s decision was also just the latest victory in a string of wins by citizens that have transformed each of the three Midlothian cement plants into more modern facilities. In 2005, Holcim Cement reached a settlement with Downwinders that resulted in the first use of a specific pollution control technology that is now standard equipment on new kilns. In 2008, TXI Cement suspended operation and then closed its four wet kilns, and stopped burning hazardous waste. Now Ash Grove is converting the last wet kilns in Texas. Comparing the emissions generated by all of the Midlothian cement plants before and after the changes sought by Downwinders over the last two decades, there’ll be at least 23,000 tons less air pollution when the new Ash Grove kiln goes online in 2014 than at the peak of the bad old days in the late 1990’s and early part of the 21^st Century at all three plants – not including the reduction of an estimated hundreds of thousands of tons of greenhouse gases like CO2 that weren’t even officially counted until recently.“I think anyone will be hard pressed to find a more successful grassroots group in the state of Texas over the last 10 years than Downwinders at Risk,” said Schermbeck. “It’s hard work to win even one of these concessions from industry. To be able to reduce this amount of air pollution from all three plants is an accomplishment that will be hard to duplicate. But that doesn’t mean we won’t be trying.”Schermbeck noted that the group has been busy pressing for the adoption of advanced pollution controls at the cement plants that have been used for a decade in Europe but have yet to reach the U.S.  He expects to see those controls included in the next DFW clean air plan. “We’re not stopping until every cement plant in North Texas is a state-of-the-art facility.”  Read More

After 21 years, four Presidents, countless political battles and lots of pollution, the EPA finally released its health reassessment of Dioxin this past Friday. Like so many environmental decisions from this Administration, the report splits important hairs. While confirming that ultra-low exposures (we're talking 1 millionth of a gram or less) to Dioxin can cause damage to a person's immune and reproductive systems, cause skin rashes and liver damage, EPA says that levels of exposure for most Americans have declined so much over the last two decades that there should be no significant risk. To at least one expert, that was an      "very odd statement." Arnold Schecter of University of Texas School of Public Health, noted that EPA's assurances really didn't jibe "because some people are more highly exposed than average and some groups, such as fetuses and nursing babies, are more sensitive to the effects." What other populations are more highly exposed to Dioxin? People who live downwind of facilities where its emitted - power plants, cement plants, and lead smelters, to name a few. DFW residents live downwind from all three. Exide's lead smelter in Frisco was the 9th largest dioxin polluter in Texas in 2009, releasing more of the poison than industrial facilities many times its size. While most exposures come through eating or drinking animal products that contain dioxin because the animals themselves were contaminated and store it in their fat, breathing in dioxins directly is also a pathway of exposure when you live near a place that burns hazardous wastes, smelts metals, or deals with a lot of chlorinated materials. Like millions of DFW residents. While there was a lot of disappointment by environmentalists at the lack of follow-through on the report, the food industry is sweating bullets over its conclusions. Last year, food industry groups wrote the EPA, stating that  most Americans could “easily exceed the daily [0.7 picogram limit] after consuming a single meal or heavy snack." Now they're afraid safer food advocates will use the report to push for new restrictions on how much of one of the most poisonous substances ever discovered can be included in their food products. Indeed. How unreasonable to expect less human-made poison dreck in your food. No release date for the part of the reassessment dealing with cancer risks.   Read More

Yet another study is out confirming the link between air pollution and brain damage. Published recently in the Archives of Internal Medicine, this is one of the largest to ever explore the connection, relying on interviews with 22,000 women over a period of six years. It concludes that long-term exposure to Particulate Matter, or soot, reduces a woman's cognitive functions. "We keep learning about more adverse effects (from pollution) than we thought possible,” said Jean Ospital, health effects officer with the South Coast Air Quality Management District who was not involved with the current research. “I’m not sure I find these results surprising,” he said, “but I’m also not sure I would have expected them if you’d asked me 10 years ago.” For years, environmental health experts have been urging regulators to get more serious about regulating PM pollution based on the wide variety of injuries it causes, even at currently "safe" levels of exposure. Regulators have stalled, because even more than smog, PM pollution is ubiquitous, being released by everything that has a flame or dust or both -  from backyard grills and home fireplaces to internal combustion engines, to industrial processes of all kinds - cement plants, power plants, smelters, gas drilling, steel mills, etc. Only last week 11 states went to court to sue the Obama Administration for purposely delaying the downward revision of PM standards, saying in their challenge that new rules for PM exposure were vital to public health. This new study links the kind of decline in brain function identified with PM pollution to an increase in dementia diagnoses, already beginning to rise significantly. This has a significant public policy aspect that was noted by the study's main author, Jeanifer Weuve of Rush University Medical Center, “What’s interesting about air pollution is that other factors that may cause dementia are generally found at the more individual level – diet, weight, smoking. And we can help to try to prevent them at that level. But in this case, we’re looking at something that we can do to intervene at a broad scale, with society at large. It's a whole new way to think about prevention for dementia and cognitive decline."  Read More

In an excellent follow-up to its "Poisoned Places" series, the Center for Investigative Reporting focuses on a Lehigh cement plant in Tehachapi California that has seen its Mercury emissions skyrocket from just over 100 pounds a year to 872 pounds in 2010 – the most of any cement plant in the Golden Gate state and the second-highest among all cement plants in the United States. For comparison, all three Midlothian cement plants just south of Dallas reported a total of 86 pounds of Mercury released into the air in 2010, 50 pounds of which comes from Ash Grove's ancient wet kilns. Relatively speaking, it looks like we're a little better off.  Except the Ameristeel Steel Mill (formally Chaparral Steel) right across the street from TXI's cement plant released 606 pounds of Mercury in 2010. That's s lot. It's also a warning sign that could eventually affect TXI's numbers. The kiln has received a new "permit amendment" nt subject to any public participation to burn Auto Shredder Residue (ASR) from Ameristeel - basically all the non-steel parts of a car after they've been through an industrial blender. This waste could have a lot of Mercury (from switches in older cars) in it as indicated by the Steel mill's emissions of the poison. When TXI burns it, that Mercury will be coming out of its own smokestack. New EPA cement plant emission standards being implemented starting in 2013 will require controls for Mercury and other pollutants at all US kilns and they're causing a once-in-a-lifetime modernization of an industry that still relies on a lot of technology from the last century that was never updated. Jane Williams, California's #1 citizen Kilnhead and the folks in Chanute, Kansas that Downwinders has tried to help get a shout-out in the piece, as does Jim Pew with the EarthJustice legal team, who've been indispensable in bringing the industry into the 21st Century kicking and screaming.   Read More

Thanks to fellow kilnhead Jim Travers, via our good and old friend Pat Costner, comes word of this new epidemiological study of the population living adjacent to, and downwind from a cement plant in Italy, published January 14th in Environment International. According to the authors, "Epidemiological studies have shown the association between the exposure to air pollution and several adverse health effects. To evaluate the possible acute health effects of air pollution due to the emissions of a cement plant in two small municipalities in Italy (Mazzano and Rezzato), a case–control study design was used. The risks of hospital admission for cardiovascular or respiratory diseases for increasing levels of exposure to cement plant emissions were estimated, separately for adults (age > 34 years) and children (0–14 years)." It will come as no surprise to most of you that the study found a strong correlation between exposure to the cement plant's plumes and getting sick. "Statistically significant risks were found mainly for respiratory diseases among children...with an attributable risk of 38% of hospital admissions due to the exposure to cement plant exhausts. Adults had a... weaker attributable risk of 23%. Risks were higher for females and for the age group 35–64. These results showed an association between the exposure to plant emissions and the risk of hospital admission for cardiovascular or respiratory causes; this association was particularly strong for children." Lest you think Italian cement plants are any dirtier than US ones, realize that the Italian multinational Italcementi S.p.A, is the 8th largest cement manufacturer in the US, and that Italy has a SCR-equipped cement plant and the U.S. does not. These kinds of studies are extremely hard to do and that's why you don't see them often. That's too bad because they're one of the only ways you can ever put the circular logic of TCEQ and industry "toxicology" to the acid test. Everything leading up to granting an permit to pollute in Texas is based on guesstimates about how the new facility or equipment will operate and what its public health impacts will be. While it's now possible to determine if the plant may or may not be complying with the purely operational aspects of the permit, what check and balance can determine that it's not causing a public health problem? For the TCEQ, it's the theology/hypothesis that it's quite impossible for long-term, low-level chemical exposures to harm people because there's no proof. When citizens directly challenge this belief system with sampling results taken even as they were experiencing adverse health effects, showing the presence of industrial by-products in the air they're breathing, but below "safe levels,"  the state says that something else must have been causing their health problems. In 2012, TCEQ is the environmental equivalent of a Medieval Pope. Don't confuse them with your evidence, they have a religion to run. Or in their case, an industry agenda to implement. This is why direct, on-the-ground epidemiological studies like this one (or even associative ones like the local Cook Children's Hospital one featured in the graphic above) are so important. They are not guesstimates. They're not an hypothesis. They're real science telling you the system is not performing as predicted. We bet the Italian cement plant's permit promises not to cause a public health nuisance. And yet it appears that it does.   Read More

As of this week, EPA officials mulling a national settlement agreement over various Ash Grove transgressions across the country know that the company is considering converting their Midlothian old wet kilns to new dry technology and can take that into account when drawing-up the terms of said settlement agreement. Also, as of this week, Ash Grove corporate headquarters knows the cat is out of the bag and the public knows it's considering the switch. That's more than either party knew last week - thanks to citizens. From all available indications, both the Ash Grove VP in charge of Environmental Affairs and the EPA's Assistant Administrator in charge of Civil Enforcement received lots and lots of e-mails yesterday about the subject because so many of you were nice enough to respond to our action alert. Thanks and well done. Having added these new ingredients into the mix, we will now stand back from the stove for a minute and watch to see how things stew. EPA could now make it clear that the national Ash Grove enforcement settlement must include a dry conversion of its Midlothian kilns. Ash Grove could decide to preempt what looks like a forced move by EPA and announce it's already made the decision. Maybe neither. Meanwhile, we're out shaking the bushes for more information. Since the company was supposed to make a decision by early December we can't help but feel some new development is imminent. Stay tuned. And thanks again for being active citizens instead of passive receptors.   Read More
