Air Quality
Maryland: Toxic Air Pollution Top Threat From Fracking
According to a state-sponsored study through the University of Maryland's School of Public Health, "air emissions trump water pollution and drilling-induced earthquakes as a top public health threat posed by future fracking projects in Maryland."
For the better part of a year, faculty surveyed previous research between the gas industry and health effects. They looked at all the possible "exposure pathways" for toxins to reach surrounding populations from gas rigs and facilities and ranked each of the threats. Air quality got a "high" threat ranking, whereas water pollution ranked "moderately high" threat and earthquakes "low."
Dr. Donald Milton, Director of the Maryland Institute for Applied Environmental Health and a UMD professor of epidemiology, biostatistics, and medicine was the study's lead investigator and concluded,
"….existing data show a clear trend: oil and gas activity can spew significant levels of toxic chemicals into the air—and that pollution consistently makes people sick.
"We think [the state] should pay a lot of attention to air pollution," said Milton. Although water pollution is also a concern, Milton told InsideClimate News that there's not enough data on how likely dirty water is to sicken people, nor how strong those health effects would be."
Because most of the reviewed data in the study comes from gas plays that have received a lot of attention over the last couple of years – the Barnett and Eagle Ford in Texas, the Marcellus in Pennsylvania, and the Bakken in North Dakota – Maryland's environmental and public health officials were quick to offer a joint damning disclaimer: "We believe it is important to note that it is largely based on information on natural gas development in areas where the pace of gas development was rapid and intense and without stringent regulations and government oversight." Well yeah, but if our own officials weren't so negligent you wouldn't have the benefit of now learning from our bad examples.
The study was part of a 2011 executive order signed by Maryland Governor Martin O'Malley that outlined a state approach to dealing with potential fracking in the state's western corner, where the Marcellus extends across the Pennsylvania line.
Besides identifying air pollution exposure as a major threat, the study also offered specific recommendations to combat that exposure, including:
– a 2000-foot setback from urban neighborhoods (Dallas and Southlake both have 1500-foot setback provisions)
– baseline air quality monitoring before any drilling or production begins
– constant air monitoring when activity on the site begins
– transparency in the information about the facility.
As the Inside Climate article on the study notes, its conclusions "stand in stark contrast to public concern in heavy-drilling states such as Maryland's neighbor Pennsylvania. Those concerns have tended to focus on tainted water, not air."
Indeed. It's a lot easier to make a fire-breathing water hose into a drive-by YouTube meme than a family gasping for air that won't make them sick. But for most neighbors of urban gas drilling, water quality isn't even on the radar screen because they're getting their H2O from a city pipe running from a lake, not a well. On the other hand, they're directly breathing in the mix of chemicals and pollution coming off the site itself, making their home a frontline toxic hot spot. That site's plume is then combining with hundreds or even thousands of other plumes from similar sites close-by to decrease regional air quality. That air pollution can end-up affecting thousands or millions of residents who don't even live in close proximity to a rig or compressor.
In the most successful "nuisance" court cases against gas operators in the Barnett Shale over the last year or so, air pollution has been the villain keeping families from enjoying their property and running up their medical bills. You can get water trucked in, but it's very hard to do the same with air.
Public comment on the report is open until October 3rd.
TCEQ: Link Between Fracking and Air Quality, No Cement Controls Just “Because”: Highlights From Tuesday’s Air Meeting
Dallas Resident Liz Alexander showed up at the Council of Governments meeting room on Tuesday to lend her support to the effort to get more out of an anemic state ant-smog plan than the state wants to give. She was a warm body whose presence would be its own statement of concern. She was being a good trooper by just showing up.
At first she sat far from the action amidst the rows of seats for bystanders and, despite encouragement, was resigned to just listening, because as she explained, "she didn't know enough to ask questions."
Then someone urged her to move up to the rectangle of tables where the presenters stand and deliver, where there are microphones to raise the volume of concerns and questions that might be posed by mind-numbing reassurances that everything is going hunky-dory. As more of these air quality meetings have occurred, citizens have been less and less shy about taking up these front row seats that look more official than the rest; look like they should be reserved for guys in suits. Increasingly they're occupied by people in street clothes.
And then, after much information had been paraded in front of Liz, she did something she did not think she was qualified to do only about 90 minutes earlier. She asked a question. It was about what assumptions had been included in the information about unspent air pollution clean-up dollars that are piling up in Austin. She got an answer from a local COG staff person in real time that satisfied her. In the space of one meeting she moved from spectator to participant.
And she wasn't the only one. More than any other meeting so far, this one involved more citizens asking more questions about more subjects – and it revealed just how thin the state's rationale is for doing nothing.
As predicted, it was a day for the Texas Commission on Environmental Quality to explain why its new DFW anti-smog plan was really going to work this time – unlike the five previous failures – and why it wasn't going to be considering any new controls on the Midlothian cement plants or on gas compressors – a refutation of the case Downwinders at Risk had made in its June 16th presentation.
But here's what really happened: For the first time in these proceedings the state admitted that oil and gas emissions have a big influence on regional air quality. And when a former County Judge asked an TCEQ's Air Quality Manager specifically why anti-smog controls already being used on cement kilns in Europe were not being considered for the Midlothian kilns, the staffer couldn't say, offering up only the longest, most pregnant pause by any state staffer in the history of these meetings.
After being heavily criticized for months for leaving at least four monitors above the 75 ppb federal smog standard even after its plan had ended in 2018, the state came back to this meeting saying they only had three sites above 75 ppb now, and by margins that didn't exceed the standard by more than 1 part per billion. Between June and August, there had been a remarkable drop in future estimated smog levels at the area's monitoring sties in the state's computer modeling – particularly at the historically most stubborn monitoring sites in Denton and Northwest Tarrant County.
What had caused this drop? A relatively modest decrease in Nitrogen Oxide pollution of around seven tons a day and a decrease in Volatile Organic Compounds of about 15 tons per day. That's not a lot of pollution to produce such a large decrease in monitor readings in the computer model.
A more important question is: where did the decreases in air pollution come from that could produce such dramatic results in the modeling? The answer: primarily from oil and gas industry sources. Based on TCEQ's own formula relying on the declining number of new wells being drilled in the Barnett Shale.
For the moment forget the methodological qualms you might have about that declining well assumption. Instead, appreciate the fact that the same state agency that couldn't bring itself to ever say the Barnett Shale was producing air pollution holding DFW back from meeting Clean Air Act smog standards now says that it's decreases in that very kind of pollution that are having such a substantial effect on the monitors in the western part of the Metromess that have been the most resistant to other control strategies. TCEQ has just proven a causal link its been denying for over seven years now.
It can't be just a one-way street. If declining oil and gas air pollution equals better air quality in the TCEQ's computer model, so increases in oil and gas pollution must lead to worse air quality.
There are all kinds of reasons to doubt that the drop in total oil and gas air pollution will happen at all or drop as fast or as sharply as the TCEQ predicts. Afterall, they're 0 for 5 in such matters. They may be underestimating the amount of total air pollution from all gas and oil sources and so the drop will not be as sharp. They may be underestimating the impact of lots of new lift compressors that will be showing up to squeeze the last bits of gas from older wells even as new wells are not drilled as often. But as of Tuesday the link has been made by TCEQ itself that such a drop results in big decreases in smog levels in Denton and Northwest Tarrant County. That's something that citizens can use to argue as proof of the impact of oil and gas facilities on local air quality.
Of course, it only took the span of about 30 minutes for the TCEQ to internally contradict itself about those results.
According to TCEQ computer modelers, natural gas Compressor Stations large enough to be considered "point sources" just like cement kilns or power plants will be responsible for over 17 tons of Nitrogen Oxides, and 26 tons of VOCs a day in 2018 – well over the amount of oil and gas pollution decreases that resulted in those lower monitoring numbers in Denton and NW Tarrant County. But according to the TCEQ staff responsible for suggesting new controls in the new smog plan, those numbers are not large enough to have an impact on improving DFW air quality or warranting a policy of electrification for those compressors that could reduce their air pollution to a fraction of those volumes.
So while 7 tons of NOx reduction from Oil and Gas sources is large enough to bring some of the most stubborn monitors down a whole part per billion, reducing air pollution from Oil and Gas sources by another 17 tons of NOx reduction would have no effect on DFW air quality at all and it's just not worth it to make them electrify compressors. Honest, that was the logic in play on Monday, and it didn't hold up very well under questions from people like Liz Alexander.
And that was all before you got to why the Midlothian cement kilns could not, no way, no how, possibly, under any circumstance, be required to install Selective Catalytic Reduction controls, just like their European counterparts have done over the last 15 years.
Turns out, it's just because.
Oh, the TCEQ staffer cited four criteria for any new control measure to meet before it could be considered. Let's see, there was "technological feasibility." Since there are at least seven full-scale SCR units up and running in Europe, that couldn't be a problem. It's accepted technology by some of the same companies operating kilns in the US – including LaFarge-Holcim.
There was "economic feasibility." And since there are all those SCR examples already in the European market and no company has gone bankrupt running them, that's also off the table. Plus the fact that the TCEQ's own 2005 study of SCR concluded it was "available technology" then that would only cost $1000 to $3,000 per ton of NOx removed – versus the up to $15,000 per ton of NOx removed ratio allowed in the state's own official diesel engine replacement program. Coming in at one-fifth the cost of what the state already said was economically feasible, it certainly ruled out that one.
There was the third criterion – that controls couldn't cause ‘‘substantial widespread and long-term adverse impacts.’’ The state said that wasn't the reason they couldn't be considered either, although the TCEQ staffers seemed to hedge a bit here, seemingly wanting to say that, really, they didn't want to cause themselves adverse impact by admitting that they had been wrong for over a decade about this stuff.
The proposed control cannot be ‘‘absurd, unenforceable, or impracticable.’’ Clearly, if the Europeans are doing it on their kilns, it's none of those either. It's quantifiable, and up and running in power plants, cement kilns and incinerators.
And it has to speed the attainment deadline by a year. No problem. SCR could do that if it was installed in a timely fashion.
So at the end of the state's presentation, former Dallas County Judge Margaret Keliher asked the TCEQ staffer exactly why SCR wasn't considered a possible pollution control measure since none of these criteria that had been presented seem to rule it out. And the TCEQ's staffer's response was…………………………………………………………………………………………………………………………………………………………………….
No, really, that was the response. She couldn't say. It was that embarrassing. Because the rejection of SCR by TCEQ isn't based on any of those criteria. It's based on a political decision that's been made that no new pollution controls will be sought on the kilns or any other major industrial polluter as long as Rick Perry is running for President. Or "just because."
How ridiculous is this? At this point the TCEQ is taking an even more regressive view of SCR controls than the cement industry itself. In June, Holcim Cement's Midlothian plant requested a permit from the state that would allow it to build either a Thermal Oxidizer or an SCR until for the control of VOC pollution. Being the free market fanatics the Perry Administration claims to be, doesn't the fact that one of the Midlothian cement plants is asking for a permit that includes the possibility of installing SCR mean it's automatically technologically and economically feasible? The market is never wrong, right? Are the folks at Holcim so enamored of kinky, off-the-wall green technology that they'll just include it in a permit for laughs? These guys are Swiss engineers. They have no sense of humor.
Denial of SCR as a viable control measure that could reduce smog pollution is making the TCEQ contort into sillier and sillier positions. It's making them deny the conclusions of their own almost-decade old report that said it was available to put in a kiln in 2005. It's making them deny the fact that SCR is up and running at over half a dozen kilns in Europe. It's forcing them to once again use the "Midlothian limestone is magically special" defense that has been used to forestall any progress in pollution control there over the last 25 years. The arguments used against SCR are exactly the same as were used against the adoption of less effective SNCR technology before it was mandated. In case you hadn't noticed, they're still making cement in Midlothian despite the burden of having to nominally control their air pollution.
The state wants to power through this anti-smog plan just like they did the last one in 2011. They don't want to have to make industry do anything. But at this point the denial of SCR as a control measure to be included in the next DFW anti-smog plan is so absurd, as is the justification for electrification of gas compressors, that it might be fodder in the next citizens lawsuit over a DFW anti-smog plan, which usually follows these things like mushrooms after a rainstorm.
Want to get involved in this fight and make it more difficult for the state to get away with doing nothing at all about DFW smog – again? Please consider attending our next DFW Clean Air Network meeting – THIS SUNDAY, AUGUST 17th, from 3:30 pm to 5:30 pm at the offices of the Texas Campaign for the Environment across from Lee Park in Dallas, 3303 Lee Pkwy, Suite #402 (214) 599-7840. Citizens are the only force that can make this plan better. Be there, or breathe bad air.
Want to Quiz the State Over Crappy DFW Air? Tomorrow’s Your Chance As the Empire Strikes Back
Rick Perry's minions at the Texas Commission on Environmental Quality (TCEQ) are drafting a new anti-smog plan for DFW this summer and fall. The only access DFW residents have to how it's being done and why are through periodical regional air quality meetings hosted by the Council of Governments in Arlington. At these meetings staff from TCEQ make presentations on why the air in DFW is getting so much better and why no new pollution control measures are needed to reach smog standards required by the Clean Air Act – despite the fact that the state is 0 for 5 in plans to attain compliance with those standards. In fact, the last such plan from Austin actually resulted in slightly higher levels of smog.
Tomorrow, Tuesday August 12th there will be another such regional air quality meeting. It's going on from 10 am to 12 noon at the Council of Government headquarters in Arlington at 616 Six Flags Road, right across from the amusement park (insert your own joke here). Of course, it's during business hours – you didn't think they're going to make it easy for the public to attend, did you?
Despite that, beginning in April more and more local residents have been showing up at these meetings to express their concern at the lack of progress in bringing safe and legal air to DFW. One of the reasons is that these meetings are the only forum available to citizens to question TCEQ staff in person – and then ask follow-up questions if you don't like the first answer. It's their only opportunity to be a kind of clean air Perry Mason and because it's a public meeting and everyone's looking at them, TCEQ staff have to at least make an attempt to answer those questions.
Things reached a high point at the last meeting in June when Downwinders and the Sierra Club were allowed to make their own presentations about why the state is falling down on its job. A roomful of concerned citizens and elected officials saw the case against the state was self-evident – all we had to do was quote from its own past press releases and memos to make our point.
Tomorrow's meeting is the first chance the state will have to give a rebuttal to those citizen group presentations. Staff will present all the reasons why we don't need new air pollution controls on the Midlothian cement plants, the gas industry, or the East Texas coal plants, and why another do-nothing anti-smog plan from Austin will be just dandy.
And so, if between inhaler bursts you ever wanted to quiz officials about Rick Perry's air pollution strategies, tomorrow's meeting is going to be your chance.
You may think you're not qualified, but you'd be wrong. Simple common sense questions are often the hardest ones for the TCEQ staff to answer, because you know, they're based on common sense, and so many of their policies aren't.
This is how citizens uncovered the fact that TCEQ was hiding oil and gas pollution in other categories not named oil and gas. This is how we got the TCEQ to release maps of where all the gas industry compressors in DFW are after first explaining there were no such maps. And so on.
All that you need is a curious mind. They're not prepared for those.
Tomorrow, 10 to 12 noon is your opportunity to show your concern about breathing bad air, your desire to see major industrial sources of pollution better controlled, and why you want these anti-smog plans to do more. Be there or keep breathing bad air.
Three Easy Pictures: Why the TCEQ Didn’t Want Compressor Locations Publicized
These are maps that supposedly weren't available…until they were.
From January all the way through June, citizens involved in watch-dogging the state's drafting of an anti-smog plan for North Texas had been asking if the Texas Commission on Environmental Quality had maps of the locations of all the gas compressors in the 10-county DFW "non-attainment" area for ozone.
The answer from the state, over the course of at least three regional air quality meetings in Arlington, was always no.
Then State Representative Lon Burnam asked the same question, officially, in a letter to TCEQ. About two weeks ago, he got these three maps in the mail. Thanks to Representative Burnam for his follow-though.
This dodge followed an attempt by the state to hide the emissions from these compressors in other categories besides "Oil and Gas" in an attempt to minimize the industry's air pollution impacts on DFW air quality.
You can understand why TCEQ wasn't eager to show these maps.
The first shows the location of 647 large gas compressors. The volume of air pollution from each of these compressors is so large that they're considered "point sources" like power plants, cement plants, manufacturing plants, etc. According to the TCEQ, these larger compressors will be emitting over 14 tons of smog-forming Nitrogen Oxide pollution PER DAY by 2018.
The second shows the approximate location of the thousands of smaller, "area sources" compressors. TCEQ doesn't really know how many of these there actually are – they've never counted and no inventory by industry is required.
Instead, the state bases the number and approximate location of these smaller compressors on the production rates of gas in the Barnett Shale, as reported by the Railroad Commission, and disperses them accordingly.
There's some question about whether this is the most accurate way to take a count – a lot of industry literature says you should use the number of wells and the age of the wells instead of the production rate because as a gas field gets older, operators use more compressors to extract harder-to-get gas.
This is important because while production rates in the Barnett Shale have gone down, the number of wells is increasing.
The upshot is that as impressive as all those dots seem in the second map, they may actually represent an underestimate of the number of smaller compressors on the ground. As it is, TCEQ estimates these compressors will collectively release another six and a half tons of smog-forming Nitrogen Oxides PER DAY by 2018. That's in addition to the pollution of the larger point source compressors.
The last map is a combination of the first two. In all three the region's smog monitors are the purple triangles. Please take note of their location as well.
For over a decade now it's the monitors at the Denton Airport and in Northwest Tarrant County – at Meacham Field, in Keller, in Grapevine and Eagle Mountain Lake – that have recorded the highest smog readings in the entire regions.
There's no question as pollution accumulates over Dallas and Fort Worth and blows Northwest, ozone levels get higher. It's also true the pollution plumes from the Midlothian cement plants can blow directly into the paths of many of these monitors. But can anyone look at these maps and not realize that these gas compressors are also contributing to the high readings being recorded at the monitors in Denton and Northwest Tarrant County?
That's the real reason TCEQ didn't want the public to see these maps.
There's another regional air quality meeting next Tuesday, August 12th in Arlington from 10 am to 12 noon at the North Central Texas Council of Government offices at 616 Six Flags Road. These meetings are the only chance that citizens have to ask questions of TCEQ staff about the information going into drafting the new anti-smog plan. Without those kinds of questions, we still wouldn't know how much air pollution these gas compressors are emitting, or their location. Rep. Burnam would not know what official requests to submit. Information is power. Come get a little more empowered this next Tuesday.
Power of the Press: Week after Trib Report on DFW Smog, First “Exceedences” of 1997 Standard
It was only eight days ago the that online Texas Tribune did the first real overview of DFW air quality for this "ozone season." Borrowing heavily from the June 16th Downwinders at Risk presentation to the North Texas regional air quality committee, it concluded that there had been no discernible progress in regional air quality for the past five to six years despite a new state anti-smog plan aimed at getting the area below the 1997 standard of 85 parts per billion.
Ironically, up to that point, DFW had been enjoying one of the wettest, coolest, most ozone alert-free summers on record. Not one 100 degree day until July and only one "bad air" days of note on June 11th. It looked like we might actually be able to meet the 1997 standard of 85 ppb for the very first time.
That's all changed with this past weeks' return to familiar form. In just seven days, they've been at least four official "ozone alerts" issued for DFW by the Texas Commission on Environmental Quality. Those had produced four "exceedences" of the current 75 parts ppb standard, which the state is now aiming at with another "do nothing" plan under development and due out by the end of the year. On Wednesday the trend got more serious with the addition of the first two "exceedences" of the older 1997 standard we can't seem to conquer – a reading of 88 ppb at the NW Fort Worth monitor at Meacham Field and a 91 at the usually quiet Granbury monitor in Hood County. In the latter case, one mid-afternoon hourly reading reached as high as 113 – just 12ppb short of a violation of an even more ancient standard left over from the 1980's.
For comparison's sake, EPA scientists just sent a letter to EPA Administrator Gina McCarthy recommending that a new, lower federal standard for ozone be set at 60-70 ppb.
It will still take another week of 85 ppb plus days to produce the "fourth highest" readings at the Denton or Keller sites to combine with their 2013 averages and keep DFW in violation of a 17-year old ozone standard. But then again, we have all of August and September to go.
Not surprisingly, two of this summer's hot spots include traditionally troublesome monitors – the Denton and NW Fort Worth site. Tarrant and Denton Counties have historically been the places where the region's highest readings have originated. One reason is wind direction – smog accumulates from upwind sources like the Midlothian cement plants and blows Northwest during the summer. Another more recent reason is the mining of Barnett Shale gas deposits that release huge quantities of smog-forming pollution in the western half of the Metromess, a phenomenon that's been examined in a new UNT study that divided the region's ozone monitors into "Fracking" and "Non-Fracking" areas and found significantly higher readings among those in the Fracking area.
As we went to press with this post, Thursday's readings looked to be producing another round of 75 ppb or higher results. Adding to this year's ozone season irony is that over the last 20 years, July has traditionally been the summer month that produced the fewest number of high ozone readings, book-ended by higher numbers in June and August-September.
Depending on the weather, DFW may still be able to make it over the 1997 standard, 85 ppb hump. But based on this past week's results, that hump just got bigger. Stay tuned.
New Encyclopedia of Fracking Harms
Those that keep up with these things know the rate of new information about fracking has increased almost exponentially for the past couple of years. New studies arrive monthly covering a host of subjects – air pollution, water contamination, earthquakes from injection wells, truck traffic, etc. So many it's hard to keep up and get a view above the fray. Now, at least for the next couple of months, there's a new comprehensive guide for journalists, citizens, and policymakers that tries to put all the latest evidence into one publication.
Produced by the Concerned Health Professionals of New York, the new document has the slightly unwieldy title of "Compendium of Scientific, Medical, and Media Findings Demonstrating Risks and Harms of Fracking." Clocking in at over 60 pages, it does manage to cover a lot of ground, including air and water pollution, occupational hazards, noise pollution, earthquakes, flooding, radioactive releases, climate change, agricultural threats, crime rates, property values, and the inflated economics of gas reserves. In short, for now, it appears to be the one-stop shop for everything you wish you didn't need to know about fracking, but wanted to ask.
Extensively researched and footnoted, the Compendium is something you can hand your city council member or State Representative in hopes that their superficial scanning at least produces a better appreciation for the myriad of hazards now associated with the practice.
Ask the State and Holcim To Finally Give DFW “the Holy Grail” of Cement Pollution Control Technology
Swiss-based Holcim Cement is requesting a permit amendment to add new piece of pollution control equipment to its Midlothian cement plant, one of three cement plants that make the city the "Cement Capitol of Texas" and the largest concentration of cement manufacturing in the U.S. Good news, right? The problem is that the company is asking the state for the permit before deciding what kind of pollution control equipment to install.
That's right. Holcim is asking the Texas Commission on Environmental Quality (TCEQ) to OK a permit that will result in a "major modification" of its Midlothian plant and could produce significant amounts of new pollution before it even decides what the major modification is going to be. Anywhere else in the country this might be a bit odd, but hey, it's Texas, where Rick Perry's TCEQ has a rubber stamp standing by for anything industry requests.
Holcim's permit request is being prompted by a problem complying with new federal regulations limiting a kind of pollution called Total Hydrocarbons, or THCs. These are also sometimes referred to as "Volatile Organic Compounds." Think Benzene, and other kinds of hazardous flammable gases. In its permit application Holcim says it needs to add new controls to reduce THC to levels and come under the new federal standard. Fair enough. The company then says that it's still trying to decide between two different types of controls and will make up its mind after getting the permit and seeing how well its choice works out on one of its two separate giant kilns. That's the bogus part.
But wait, there's more! The two technologies Holcim is considering installing in Midlothian are: 1) A Regenerative Thermal Oxidizer, or RTO, which is a fancy way of saying setting them on fire and flaring them off, and, 2) A Selective Catalytic Reduction unit, or SCR, which is a tower of treated metal honeycombs that pick up pollution as the plant exhaust passes through them. RTOs are already installed on American cement plants, including TXI's huge Midlothian kiln just a few miles down Highway 67 from Holcim. On the other hand, up to now full-scale commercial SCR units have only been installed on European cement plants and in fact, the Portland Cement Association has lobbied long and hard to keep them out of the US for fear of raising the pollution control bar too high for all of the country's cement plants.
That's because SCR is more expensive to build and maintain than most cement plant control devices. But for the money, you get the Holy Grail of cement plant pollution control technology.
Most of the European cement plants that have SCR units install them to remove another type of pollution from their stacks – Nitrogen Oxides (NOx). If that sounds familiar, it's because NOx is a major smog-forming pollutant, and DFW has so much of it that the region has never been in compliance with the Clean Air Act standard for smog. And you'll never guess which facilities are the single largest sources of NOx pollution in North Texas. Or maybe you will: the Midlothian cement plants. That's why Downwinders at Risk has made it a point to campaign to require all three Midlothian cement plants – Holcim, TXI and Ash Grove – to install SCR….since all the way back in 2001, when the first European units were deemed a success at a German cement plant. SCR can remove 80 to more than 90% of all NOx coming out of a cement kiln. The 6500 tons of NOx a year that the Midlothian cement plants are permitted to release could be reduced to 650 tons with the application of SCR.
Now, as it turns out, SCR units are great not only at capturing large amounts of NOx pollution, but all kinds of other industrial pollution coming out of cement plants as well. Like THCs – up to 70% or so, but also Particulate Matter, Metals, Greenhouse Gases, Carbon Monoxide, and Dioxins. It's what's called a multi-pollutant control device because it does such a good job of eliminating a wide variety of nasty stuff from smoke stacks. This is what makes it the state-of-the-art technology for communities hosting kilns. In contrast, RTOs are single-purpose pollution devices aimed just at hydrocarbon removal and aren't designed to remove other kinds of emissions.
So even though Holcim is considering operating SCR because of its hydrocarbon problem, it would have a massive impact on the plant's air pollution across the board. And if Holcim were to set the precedent, the clock would begin ticking on bringing SCR to the other two Midlothian cement plants as well. It would only be a matter of time.
The public comment period for telling the state whether to accept or reject Holcim's permit application ends this Friday, July 11th at 5 pm. (If you're interested in jumping through the hoops to fill out the online form for official comments, you can go here and use Permit Number 8996)
Downwinders is submitting detailed comments praising Holcim for considering SCR, but urging the TCEQ to reject this permit because it's too vague and doesn't commit the company to any partciular technology, including SCR. We've also been collecting letters form local officials and stare legislators that urge Holcim to definitively choose SCR.
Now we're asking you to help us bombard both the Texas Commission on Environmental Quality and Holcim's US headquarters in Dundee Michigan in the next 48 hours with the same message to show public support for the company to do the right thing while rejecting a placeholder permit that doesn't commit it to do that right thing.
We want a permit request from the company that says Holcim will definitely install SCR, becoming the first commercial application of this state-of-the-art technology in America.
Using our "Featured Citizen Action" link, you can send such a message to Austin and Michigan in a matter of seconds right now. All you have to do is click here and then send the e-mails. We guarantee there's no more important or easier thing you can do for clean air in North Texas this week than sending these e-mails to the TCEQ Commisisoners and Holcim Corporate leadership. Please help us get the cement plant pollution control technology DFW deserves. It will only take a matter of seconds for you to help us achieve a goal we've been working toward for 14 years. We can do this. But we need your help. Now. Thanks.
Mansfield Gas Well Awareness Group Opens Up New Front in DFW Urban Drilling Fight
Ever since winning the Dallas Gas Wars in December of last year, Downwinders at Risk and our partners at the Texas Campaign for the Environment have been looking for a place and time to take the responsible drilling fight deeper into the Barnett Shale. We're glad to announce that we're teaming up with the newly formed Mansfield Gas Well Awareness group to do just that.
Mansfield is a relatively small Tarrant County town with a big gas industry presence. Sandwiched between Arlington and Fort Worth, it has a population of 59,000 spread over 36 square miles. it already has 200 wells on 51 gas pads with a total of 512 planned – or an average of 14 per square mile. Many of the most problematic wells are operated by Eagle Ridge – the same company whose antics single-handedly began the current "ban fracking" campaign in Denton. Like Denton, Eagle Ridge's Mansfield wells are close to homes, and have been known to spew surrounding neighborhoods with their own scrubbing bubbles concoction from flowback operations and incurred a rare violation notice from the state in February. The city also hosts a notorious Teas Energy Midstream compressor station that's a suspect in showering homes with an oily film from what was most likely from a messy blown down accident in May.
Those incidents got people's attention. Seeing themselves as the victims of a permissive "Fort Worth Model" of gas regulation, local residents are now moving to organize around a citizen-friendly "Dallas Model" with more protective setbacks, restrictions, and monitoring. As their new website and Facebook page notes, "Mansfield Gas Well Awareness is not a movement against natural gas or exploration of natural resources. Rather, we are against the permitting of toxic gas well activities near homes, schools, day cares, and parks. We are a movement of concerned residents that live in Mansfield who are for clean air, safe and healthy communities, and protecting peoples' rights to peacefully enjoy their property."
As is so often the case, pollution problems on the ground are connected to ethical problems at City Hall. Mansfield councilman Stephan Lindsey, who until recently was Mayor Pro-Tem is Senior Director of Government and Community Affairs for Quicksilver Resources, "a Fort Worth natural gas and oil exploration company" who never feels compelled to recuse himself from any votes concerning the municipality's regulation of the gas industry. Councilman and New Mayor Pro-Tem Larry Broseh is owner and President of Cam Tech, a company "dedicated to providing the drilling industry qulity pipe handling equipment," and also doesn't mind using his public office to vote on behalf of his industry interests. That means almost a third of the seven member Mansfield city council has professional gas industry ties.
As it happens, Mr. Lindsey is up for re-election next May. Old timers might recall that the Dallas drilling fight got real traction when gas friendly incumbent city council member Dave Neumann was upset by newcomer Scott Griggs way back in 2011. Although the new group hasn't officially targeted Lindsey, defeating him with a candidate more skeptical of industry claims would certainly send a strong message that Mansfield residents don't want the fox guarding their chicken coops.
The good news is that Mansfield Mayor David Cook took MGA members up on their invitation to see the Downwinders' presentation to the regional air quality meeting in Arlington on June 16th, where Director Jim Schermbeck devoted half of his time to explaining why gas compressors should be electrified. As far as we know, Cook was the only DFW are Mayor in attendance and it was a real coup for the young group to get him there.
MGWA's website already has some amazing pics and videos, as well as depressing factoids to share. If you know someone living in Mansfield, please let them know a new voice for citizens concern in on the scene and organizing to clean up the current messes as well as prevent new ones. Now that Downwinders has joined the fight, we'll certainly keep you posted on developments as well. Westward ho!
EPA Scientists Say Current Smog Standard Not Protective Of Public Heath Even While TCEQ Blows Off Current One
It's been a pretty nice summer in DFW so far hasn't it? Wetter and cooler than usual. More wind. According to the stats, this past month was the first June without any 100 degree days in seven years or so. Consequently, it's also the first June in forever that hasn't seen any "Orange" or "Red" ozone alert days. If this keeps up, DFW may actually come into compliance with the 1997 ozone standard of 85 parts per billion (ppb) over an 8-hour time period – a first as well.
But unless you think "global weirding" is going to produce these kinds of summers routinely from here on out, there's little cause for comfort. This year's cleaner air is a direct result of cooler weather. Substitute the hellish summer of 2011 for this mild one and you'd be seeing ozone alerts filling up your e-mail box. As a result, it's not out of the question we could meet the standard this year, but flunk it in 2015 if the weather reverts back to "normal."
In addition, while we may come in under the 1987 smog standard for the first time, the public health goal posts have moved with better science. In 2008, the Bush Administration lowered the acceptable level of smog to 75 ppb. That's the goal of the clean air plan that Downwinders and other groups are fighting the state over right now, saying it's not adequate to even get to that 75 ppb level.
Texas Commission on Environmental Quality staff say we don't need to implement any major pollution control measures on cement kilns, power plants, or natural gas facilities to reach this 75 ppb goal by the deadline in 2018. All we have to do is sit back and let a new federal gasoline standard hit the market in 2017 and we'll all be fine – well, except for those millions of residents who'll be breathing-in smog greater than 75 ppb on the north and western side of the Metromess. But the TCEQ staff say we'll be "close enough." No harm, no foul say the folks from the agency where smog is not considered bad for you.
But close enough should only count in horseshoes and hand grenades, not what people breathe into their lungs. And while some of us are trying to make sure the new TCEQ plan is serious about reaching an air quality goal that's now six years old, the level of ozone considered "safe" by experts is once again going down.
In a letter to EPA Administrator Gina McCarthy last week, the Agency's own Clean Air Scientific Advisory Committee (CASAC) recommended a new smog standard of between 60 and 70 ppb, saying that there's a boatload of evidence showing that the 75 ppb level is not protective of human health, and even at 70 ppb there's significant public health harm done by bad air.
"At 70 ppb, there is substantial scientific evidence of adverse effects….including decrease in lung function, increase in respiratory symptoms, and increase in airway inflammation. Although a level of 70 ppb is more protective of public health than the current standard, it may not meet the statutory requirement to protect public health with an adequate margin of safety….our policy advice is to set the level of the standard lower than 70 ppb within a range down to 60 ppb…"
This recommendation was not unexpected. Every five years, the CASAC is legally obligated to review the scientific literature to make sure the federal ozone standard is giving adequate protection to public health. The last time it did so in 2008, the panel came to a similar conclusion to lower it somewhere between 65 and 70 ppb, but the Bush Administration ignored its own scientists and chose the higher standard instead. An Obama EPA was supposed to correct that mistake when it came into office, but then-EPA head Lisa Jackson got mugged on her way to the White House by the President's re-election campaign. Any changes were put on hold until that five year review clock began ticking again. And now the official alarm has gone off on that clock. The result is a re-affirmation of the earlier findings, this time with even more science to back up the changes.
As a result, EPA will have to decide whether or not to adopt the tougher recommendations of its scientists by December 1st of this year. If they do, a new standard will be officially adopted by 2015 and we'll have to write a new clean air plan in a couple of years to achieve that goal by the end of the decade. If it doesn't, they'll be sued, with the CASAC letter as exhibit #1, and they'll lose and have to set a new standard anyway.
Why is that important to the current debate over TCEQ's plan to meet the 75 standard? Because the TCEQ plan leaves at least four monitors, spread out from Denton, to Keller, to Eagle Mountain Lake above 75 ppb – a standard that EPA scientists now say conclusively is not protecting public health.
"Close enough" to that 75 ppb level turns out to be too far away from real protection in light of the new recommendations for a standard below 70 ppb from the Science Advisory Committee. And that assumes you believe the computer modeling TCEQ has done to support its plan. To date, the state is 0 for 5 going back to 1991 in being able to accurately predict these things. If history is any indication, the state's plan will fail to reach its goal of 75 ppb at just about every one of the 20 monitors in DFW, not just four.
If you know your target of 75 ppb of smog over an 8-hour period is no longer a safe standard, and your current plan condones levels above that, it's not really a clean air plan.
December is not only when EPA must decide if it's going to pursue a lower smog standard. It's also when the state is scheduled to take public comment on its current DFW anti-smog plan. So you have the surreal possibility of holding public hearings over the merits of an already obsolete plan that isn't even serious about reaching its obsolete goal.
This is why DFW residents must demand a plan from Austin that aims lower, not higher. It's why they must demand the EPA not allow TCEQ to get away with being "close enough" to a standard that's not protecting their health. A real clean air plan would be shooting for an average of 65-70 ppb knowing that that standard will be coming down the road sooner or later. A real clean air plan wouldn't allow any monitor to exceed the current 75 standard. A real clean air plan would try to do its best to protect public health by implementing pollution control measures on the sources of smog that are the cheapest and most effective to target – Midlothian's cement plants, east and central Texas coal plants, and the natural gas industry.
And that's exactly what Downwinders and other members of the new DFW Clean Air Network are trying to do. We're pushing for stricter EPA enforcement of the 75 ppb standard, and we're pushing for adoption of "Reasonably Available Control Measures" on the cement plants and gas compressors – now, not later. Because the only way DFW breathers are going to get a better clean air plan out of Austin and Washington is by organizing for one themselves.
Study: Climate Change Will Likely Increase DFW Smog
Just last week at the June regional air quality planning meeting the Texas Commission on Environmental Quality was bemoaning the fact that the weather too often determines how bad an "ozone season" DFW will have. And it's true. When we have really hot, dry, and windless summers, ozone levels soar as they did as recently as 2011-2012 when the recent drought seemed to reach its most awful heights in DFW. Conversely, when we have relatively cool, wet and windy summers, ozone levels abate, as they seem to be doing this year – at least so far.
Of course, the TCEQ spokesperson was using weather as an excuse why DFW hadn't yet achieved compliance with the 1997 ozone standard after two tries that fell short. Completely overlooked was the fact that the last state air plan for DFW in 2011 promised historically low ozone levels by 2013 without any new pollution controls on major sources of pollution. Combine that lack of action with a really hot, dry summer like we saw in 2011, and you get the first clean air plan ever to leave ozone levels higher after it ended than when it started.
That's why it's important to think about the weather when you're trying to build new clean air plans for DFW that stretch years into the future. Air quality planners have to ask themselves if between now and the next federal clean air plan deadline of 2018, will there be more summers like this seemingly anomalous one, or will they more like the summer of 2011 when we had a constant barrage of 100 degree plus days as early as March?
Currently, the TCEQ is using a stretch of bad air days from 2006 to predict ozone levels between now and 2018 in their computer model for the DFW air plan to comply with the new, tougher 2008 ozone standard. But 2006 was pre-drought. Although they say they're "adjusting" the meteorology to compensate for weather changes since then, do you really trust TCEQ to assume worst-case weather scenarios when they're still trying to hide the smog impacts of gas pollution from the public? Us either.
So it's with more than a little self-interest that we note a new Stanford study with the too-sexy title of "Occurrence and Persistence of Future Atmospheric Stagnation Events" concluding that the Western US, including Texas, should expect hotter and therefore smoggier summers thanks to climate change. Why? Because hotter temperatures will slow the flow of air around the globe. That means less wind, and less wind means more time for smog-forming chemicals to sit and bake in the hot sun and form harmful levels of ozone. Historically, most of our worst ozone days are when winds are blowing less than 5 mph – stagnate air.
DFW isn't like Denver or LA where mountains form bowls around the urban areas and trap pollution in inversions. But the new study concludes the impact from global warming could have the same effect on the Texas prairie by stagnating air currents:
"Our analysis projects increases in stagnation occurrence that cover 55% of the current global population, with areas of increase affecting ten times more people than areas of decrease. By the late twenty-first century, robust increases of up to 40 days per year are projected throughout the majority of the tropics and subtropics, as well as within isolated mid-latitude regions. Potential impacts over India, Mexico and the western US are particularly acute owing to the intersection of large populations and increases in the persistence of stagnation events, including those of extreme duration. These results indicate that anthropogenic climate change is likely to alter the level of pollutant management required to meet future air quality targets."
And who's more prepared to deal with the "pollution management required to meet future (re: tougher) air quality targets than the Texas Commission on Environmental Quality? Almost any one, including your 13-year old niece who's done so well in 8th grade science this year. Because not only is it the TCEQ's official position that smog isn't all that bad for you, but that there's really no such thing as climate change. It's why you should bring a boatload of skepticism to the computer model that's driving the currently proposed DFW clean air plan. To plug hotter and hotter temps into the DFW smog model for coming years would be admitting to a phenomena that the Rick Perry administration in Austin just can't bring itself to concede. One more example of how the DFW plan is being driven by politics, not science.
As the TCEQ's own staff admitted last week, DFW's ozone levels are often hostage to the weather. If you're model isn't correctly estimating the weather during future ozone seasons, chances are your estimates of future ozone levels will be off as well. But of course, since smog isn't really bad for you there's no downside to being wrong about these things at TCEQ HQ, and only an upside in GOP primaries.
For the rest of us who believe what the science tells us, the consequences are more dire. As the VICE magazine take on the Stanford study said:
"….one reason this study is so important to the climate change conversation—it underlines the public health threat posed by climbing temps. When Obama was touting the EPA's new carbon regulations, he emphasized the public health benefits of drawing down emissions: It would reduce asthma and respiratory illness, he pointed out. But that's largely because shuttering dirty power plants cuts both carbon and particulate pollutants simultaneously; fighting climate change also means fighting asthma.
Now, scientists have demonstrated there's an additional layer of concern to grapple with on the pollution front; climate change is going to begin blocking cities' toxic release valves. If we don't work to slow carbon emissions, these steamier cities will find their streets clogged with stagnant smog. Scrubbing that pollution and finding novel ways to clear the air, too, then, will prove to be a pressing concern in the not-so-distant future.
