By now many of us know that Earth Day is this coming Monday.  Countries around the world have been celebrating Earth Day every April 22 since 1970, when the Clean Air Act was enacted.  It’s a day when citizens of the world stop for just a moment to appreciate the planet on which we live, reflect on how to protect our precious resources, and most importantly, improve the sustainability and quality of life for all.

According to Wikipedia, the April 22 date was designated as International Mother Earth Day after the United Nations adopted a resolution in 2009.  Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 192 countries each year.

Because April 22 falls on a Monday this year, many Earth Day events throughout the state of Texas will be held on Saturday and Sunday.  I have the happy privilege of joining some of my fellow EDFers on Saturday and Sunday at the Earth Day Dallas festival, where we invite all of our Texas Clean Air Matters readers to visit and say hello.  We will have coloring activities for those young, budding environmentalists and information on all of EDF’s initiatives.

This year, we will have EDF representatives talking about the environment related to oceans, ecosystems, our Climate Corps and Texas’ energy resources.  Naturally, I’ll be on the lookout for all things related to air quality and promise to remind visitors of the significance of the Clean Air Act.

Ozone Action Days: What Do They Really Mean

This post was written by guest blogger Deanna Altenhoff, Executive Director of CLEAN AIR Force of Central Texas.

We are all familiar with the term “Ozone Action Day” and typically associate it with a hot summer day.  But what does it really mean?  The CLEAN AIR Force of Central Texas, the only non-partisan, public/private organization in Central Texas exclusively focused on air quality improvement, explains the significance of ozone pollution – and what you can do to make a difference. The CLEAN AIR Force Board of Directors consists of 32 executives from both the public and private sector, including Dr. Elena Craft of the Environmental Defense Fund, united in the common goal of finding workable solutions for improving our region’s air quality. The CLEAN AIR Force is not about waiting for the federal government to tell us what to do to clean up our air; we’re about taking early action now to keep air quality decisions at the local level.

The CLEAN AIR Force oversees a number of voluntary air quality programs that serve the public and help to reduce ozone levels in the Central Texas region. Two examples of those programs are the Clean Air Partners Program and the Clean School Bus Program.  We help implement and coordinate the air quality improvement efforts of local businesses, governments and organizations through our Clean Air Partners Program and we help retrofit and replace older polluting school buses with newer cleaner technologies and implement anti-idling policies through our Clean School Bus Program.  Educating citizens on what they can do to reduce their emissions is also a key part of our mission.

Central Texas is considered near-nonattainment for ground-level ozone under the Environmental Protection Agency’s (EPA) National Ambient Air Quality Standards (NAAQS). The ozone standard is currently set at 75 parts per billion (ppb) and the Central Texas Design Value for 2012 was 74 ppb. Despite two new and lower ozone standards in the past 16 years and a doubling of the population in the last 22 years, Central Texas has been able to avoid nonattainment because of positive weather conditions and the many pro-active air quality efforts our region is making, but there are many challenges ahead.

EPA has announced they may lower the existing standard of 75 ppb to 60-70 ppb by the end of 2013. This means we must continue to work together as a region to significantly lower our ozone emissions or risk being designated as nonattainment, which would negatively impact both public health and the health of our economy.

So what’s so bad about ozone health-wise? Ozone is a form of oxygen that is formed through chemical reactions between natural and man-made emissions of Volatile Organic Compounds (VOCs) and oxides of nitrogen (NOx) in the presence of sunlight.  Sources of VOCs and NOx include automobiles, boats, refineries, chemical manufacturing plants, solvents used in dry cleaners and paint shops, and wherever natural gas, gasoline, diesel fuel, kerosene, and oil are combusted.

Ozone Season in Central Texas runs from April 1st to October 31st. Ozone pollution is mainly a daytime problem during summer months because warm temperatures are key to its formation. When temperatures are high, sunshine is strong, and winds are low, ozone can accumulate to unhealthy levels. Read More »

Now You Can Use Your Smartphone To Check Houston Smog Levels

This post was written by Larry Soward, Air Alliance Houston Transition Director.

Source: Air Alliance Houston

Houston area residents can now track ozone pollution levels anytime, anywhere with a new groundbreaking Smartphone app created through a partnership between Air Alliance Houston, the American Lung Association Plains-Gulf Region, and the University of Houston Honors College.

This exciting new tool extends the resources already available through the Houston Clean Air Network website – the first real-time ozone website for the Houston region – developed by these three groups through a generous grant from the Houston Endowment. The Houston Clean Air Network website and now the Smartphone app enable citizens of the Houston region to get up-to-the-minute air quality information and take control over their own exposure to ozone, reducing the associated health effects.

The new “Ozone Map” app is available free on iPhone and iPad through the Apple App Store and on Android devices through Google Play.

Although individuals are currently able to check ozone values at monitor locations through various government agencies, that data available is typically about 1.5 hours old. This is important because ozone values can change quickly, and people in sensitive groups need to know actual exposure levels. “Ozone Map” provides a unique visual representation of how the real-time ozone levels are moving throughout the Houston area. Displayed much like a weather radar map, users can see the ozone “cloud” moving across the Houston area, as well as the ozone levels in different parts of the city. Read More »

What More Sound Science Does The TCEQ Need?

This blog post was written by Larry R. Soward, and it originally appeared on the Air Alliance Houston’s blog.

In our December 2012 article, “New Soot Standards Will Better Protect Public Health,” we wrote about the new, stricter national air quality standard for fine particulate matter adopted by the U.S. Environmental Protection Agency (EPA). Particulate matter (PM) is one of the six "criteria" pollutants considered harmful to public health and the environment for which the EPA is required to set National Ambient Air Quality Standards. PM that is 2.5 micrometers in diameter or smaller — called “fine particulate matter” or “PM2.5” and commonly known as “soot” — is of greatest concern because of its significant health effects on people with heart or lung diseases, children and older adults.

Because reductions in fine particle pollution have direct health benefits including decreased mortality rates, fewer incidents of heart attacks, strokes, and childhood asthma, the new PM 2.5 standard is predicted to have major economic benefits with comparatively low costs. The EPA estimates health benefits of the new standard to range from $4 billion to over $9 billion per year, while estimated costs of implementation range from $53 million to $350 million. While the EPA cannot consider costs in selecting a standard under the federal Clean Air Act, those costs are estimated as part of the careful analysis undertaken for all significant regulations.

Strongly supportive of this new, more health-protective standard is a landmark study recently announced at a conference of the American Association for the Advancement of Science and published in the American Heart Association journal. The study found a direct link between out-of-hospital cardiac arrests and levels of air pollution from PM and ozone. Conducted by Rice University researchers right here in Houston and based on 8 years of data collected from Houston's network of air quality monitors and more than 11,000 concurrent out-of-hospital cardiac arrests logged by Houston Emergency Medical Services, the study shows that the risk of cardiac arrest ratchets up significantly as the amount of air pollution increases.

Rice statisticians Katherine Ensor, a professor and chair of Rice's Department of Statistics, and Loren Raun, a research professor in the department, found that a daily average increase in fine particulate matter of 6 micrograms per day over two days raised the risk of cardiac arrest by 4.6 percent, with particular impact on those with pre-existing, but not necessarily cardiac-related, health conditions. The study also found that increases in ozone levels produced similar results, but in a compressed timeframe. Each increase of 20 parts per billion of ozone over one to three hours also increased the risk of cardiac arrest, reaching a peak of 4.4 percent. The risks were higher for men, African-Americans and people over age 65. Ensor and Raun noted that 55 percent of the cardiac arrest cases occurred during the summer months, the period of typically high ozone levels in Houston. Approximately 300,000 persons in the U.S. experience an out-of-hospital cardiac arrest each year, of which over 90 percent die. Read More »

TCEQ’s Misplaced Priorities

Adrian Shelley, Community Outreach Coordinator at Air Alliance Houston

This blog post was written by guest author Adrian Shelley, Community Outreach Coordinator at Air Alliance Houston.

If there were any doubts about the Texas Commission on Environmental Quality’s (TCEQ) priorities, they were removed at a public hearing yesterday. The hearing was poorly attended, with zero testimony from Texas’ industry. It seems that industry is so confident that TCEQ has its best interests in mind that it isn’t even bothering to show up anymore.

Yesterday’s hearing was about a proposed rule relating to Houston’s failure to attain a decades-old ozone pollution standard. At Air Alliance Houston, we’ve made our opinion on the proposed rule well known: it is designed to avoid imposing any obligation whatsoever on polluters. Yesterday we told TCEQ that this is the wrong approach and a missed opportunity for the Houston region.

When the Environmental Protection Agency (EPA) made a finding last year that the Houston area failed to attain the 1979 one-hour ozone standard, the door opened on a new regulation—the section 185 fee. The fee creates an incentive for polluters to reduce their emissions. If they cut emissions by 20 percent, they don’t pay the fee.

But thanks to TCEQ, polluters won’t be paying any fees, ever. The agency proposes to pay the fee for the polluters, using money that Houston area drivers already pay into emissions reduction programs. In other words, in order to avoid making major polluters pay a fee, TCEQ would rather you, a Texas driver, pay that fee.

Of course industry will allow this to happen. Quietly. Not a single person spoke in support of TCEQ’s proposal yesterday. Why would they? Industry knows that the agency is already working in its best interests, and it sees no need to advertise this in a public forum. The absence of industry testimony yesterday demonstrates what we already knew—TCEQ places protecting industry ahead of bettering our environment.

Everyone deserves to breathe clean air, and TCEQ should use every opportunity to clean up our air. Yesterday, Air Alliance Houston let TCEQ know that, in its haste to forgive polluters, the agency was missing another opportunity. A representative from Sierra Club also spoke, taking TCEQ to task for shifting the fee obligation from polluters to Texas drivers.

It’s not too late for you to speak up, too. Environmental organizations across Texas are submitting written comments criticizing the proposed rule. We have until Monday to let TCEQ know that we don’t approve of its decision to keeping working for industry and sacrificing the air that we breathe. If you want to write to TCEQ, you can learn more about the fee here.

Speak up, and let TCEQ know that it works for you.

Time Is Running Out To Set Stronger Limits On Soot Pollution

Credit: Mom's Clean Air Force

This blog post was written by Molly Rauch, and it originally appeared on the Mom's Clean Air Force blog.

On December 14, the Environmental Protection Agency is scheduled to release a final standard for allowable levels of soot in ambient outdoor air. Moms Clean Air Force supporters have been speaking up since the proposed standard was released for public comment back in June, urging the agency to finalize a strong standard that will adequately protect children from the microscopic particles that lodge deep in the lungs and cause a myriad of health problems. These particles originate where fossil fuels are burned, such as in cars, trucks, and power plants.

I’ve written before about some of the ways soot affects children. But as we near December 14, I feel compelled to add even more reasons for you to help us keep the pressure on EPA.

  • Soot exposure specifically harms babies, by causing premature birth and low birth weight. Fetuses exposed to more soot are born smaller and earlier compared to fetuses exposed to less. The evidence for these adverse reproductive health effects is strong and growing stronger. A 2011 systematic review of the scientific literature examined 41 published studies on the topic and found that PM2.5 exposure was consistently associated with low birth weight, preterm birth, and small-for-gestational-age births. So, soot gets inside pregnant women’s bodies and harms our babies before they are even born. No consumer gizmo can solve this problem; no high tech HEPA-filter vacuum will fix this; no special mask to wear while behind the wheel will take this away. This is a job for big government, in the best sense of the term. EPA needs to take strong action against these invisible particles harming our future.
  • Lest you think that such effects on newborn babies don’t sound like a big deal, premature birth and low birth weight are linked to some serious health consequences. Low birth weight is a potent predictor of infant mortality as well as subsequent illnesses in infancy and childhood, such as cerebral palsy, deafness, blindness, lung disease, asthma, and cognitive development. Similarly, preterm birth is associated with infant mortality and health problems in childhood and adulthood. But the harm doesn’t stop in childhood. A growing body of evidence suggests that low birth weight and preterm birth predict several important aspects of health well beyond childhoodFor example, low birth weight is associated with heart disease, heart attacks, and Type 2 diabetes among adults. It is unknown whether the low birth weight caused by soot is the same low birth weight that increases diabetes risk. But in a country like ours, where 12% of all live births are preterm and 8% of babies are low birth weight, and where these adverse birth outcomes disproportionately affect poor and non-white babies, I don’t need to wait for definitive scientific proof. Let’s take reasonable measures to continue to reduce soot exposure. We know it will improve the health of our population right now. And it just might have the added benefit of protecting infants from future chronic health problems like heart disease and diabetes. Win-win, right?
  • Soot exposure from traffic pollution is hardest on poor and minority communities. Here’s why: Traffic emissions are one of the largest sources of soot pollution in cities, and the concentration of traffic pollutants is highest near roadways. Heavily trafficked roads are basically corridors of pollution in many cities, and these are the same areas where you’ll find higher density of residences, schools, stores, and workplaces. (According to EPA, more than 45 million Americans live within 300 feet of a highway.) African Americans and low-income neighborhoods are closer to major roadways, and so they bear the brunt of this pollution. Can you say “vicious cycle”? The new soot standard will require cities to measure soot pollution near roads. There won’t be a simple fix for this kind of injustice, but taking some measurements to get a handle on the problem is a key first step. Bravo to EPA for including near-road monitors in the draft soot standard. Let’s make sure we’ll be reading about near-road monitors on December 14, when we see the final standard.
  • Limiting soot pollution helps avert climate chaos, ensuring a healthier future for our children, our children’s children, and beyond. Black carbon, the main component of soot, is a significant climate forcer. This means that it absorbs sunlight, increasing the heat-trapping qualities of our atmosphere and raising temperatures. An important quality of black carbon is its short lifespan. It stays in the atmosphere for 1-4 weeks as opposed to centuries, as is the case with carbon dioxide. This means that reductions in emissions of black carbon would have immediate climate benefits. Less soot means less asthma and stroke and heart disease – but it also means less black carbon, and therefore less climate change, which is no small threat to our health. Air pollution and climate chaos go hand in hand. Improving one helps the other.

The Costs Of Particulate Matter To American Health

This blog post was written by Dr. Bonnie New, former Director of Health Professionals for Clean Air.

Physicians treating patients with respiratory symptoms look for underlying causes or aggravators, and that includes exposure to air pollution.

If that pollution involves particulate matter – also known as soot – their concerns intensify, because of its well-known negative health impacts.

Many studies demonstrate associations between short- and long-term exposures to fine particle air pollution (PM2.5) and cardiopulmonary disease and mortality.

PM2.5 exposure is also associated with:

  • endocrine and reproductive dysfunction, including pre-term and low birth-weight babies;
  • increases in lung cancer;
  • increases in the development of vascular disease; and
  • increases in diabetes mortality.

In addition to aggravating existing asthma and other lung diseases, PM2.5 has been linked to retarded lung growth and reduced lung function in children, and even with de novo (newly occurring) development of respiratory problems in infants and children. Research also shows that reductions in PM2.5 are associated with reductions in adverse health effects and improved life expectancy.

It’s important to state here that currently, there is no identified level of PM2.5 that is known to not make people sick.

The groups most susceptible to adverse health effects from PM2.5 are infants, children, teens, the elderly, and those with existing lung and cardiovascular problems. Taken together, this represents almost half of the U.S. population.

Impacts to the Economy

When we see the large impacts of pollution on health, it’s impossible not to notice the financial impacts as well.

The economic impact of preventable illness and death related to soot pollution in the U.S. is staggering, estimated in the hundreds of billions of dollars every year. The functional impact on the lives of those affected and their families is also dramatic.

As doctors, we deal with not only the challenges of diagnosis and treatment, but with the sadness, frustration and pain of people who can not live normal lives and children who can not enjoy just being kids.

It raises anger in physicians to hear from those opposing health-based air quality regulations on the basis that such regulations would be “too costly”. It’s not like the costs are avoided if regulations are not put into place. The costs are simply shifted to our patients, and to the health care system. The costs are paid for in lives impaired and lives lost, in kids who can’t run and play, in increasing hospitalizations and people missing work and school because they’re sick.

Shifting costs like this from polluters to the general public makes for healthy business profits, but sick and unhappy people. As patient advocates, doctors have good reason to be angry. The public, those current and future patients and families, do too.

Texas Plays At Collecting Fees From Ozone Polluters

Source: www.kidsstuffworld.com

This blog post written by Adrian Shelley originally appears on the Air Alliance Houston blog.

Earlier this year, we wrote about the consequences of Houston’s failure to meet a thirty year old one-hour ozone pollution standard. The federal Clean Air Act imposes a penalty fee on major sources of ozone-producing pollutants in areas, like Houston, that have failed to attain this standard. In 2009, the Texas Commission on Environmental Quality (TCEQ) proposed a rule to begin collecting these fees, which are called section 185 fees after the section in the Clean Air Act that imposes them. It was estimated that Texas would collect between $73 and $125 million in section 185 fees per year for the Houston-Galveston-Brazoria (HGB) area.

For reasons related to shifting Environmental Protection Agency (EPA) policy and Texas’ status under another, more recent ozone standard, TCEQ’s 2009 rule was never finalized. In our last writing on the issue, we expressed our hope that the fees would eventually be collected and the money used to improve air quality in the Houston area.

Now, three years after TCEQ proposed its original section 185 fee rule, the Commission has proposed a new rule. Unfortunately, the new rule makes it apparent that TCEQ has no intention of ever collecting any fees. It is possible, though unlikely, that EPA could review Texas’ rule and conclude that it doesn’t satisfy the requirements of federal law. If this happened, EPA would be required to collect the money itself. Although this is a remote possibility, it highlights the fact that Texas should have a robust section 185 rule that ensures that this money stays in the Houston area where it belongs.

A section 185 fee program that complied with the unambiguous requirements of the Clean Air Act would collect a fee per ton of emissions of certain ozone precursors – volatile organic compounds (VOCs) and nitrogen oxides (NOx) – emitted in excess of 80% of an established baseline amount. The fee, adjusted for inflation, amounts to $8,630 per ton in 2008, the first year it should have been collected in Houston. The fees, which could approach $100 million each year, would be collected from major sources of emissions in Houston and, ideally, be used to reduce air pollution in the Houston area. They would also serve as a powerful economic incentive for industry to cut emissions.

TCEQ’s proposed section 185 fee rule does not follow this model. It seems to have been designed to ensure that polluters won’t ever pay a dime. To begin with, the TCEQ proposes to let industry offset its fee obligation against money that is already being collected from Houston area residents for other pollution reduction programs: the Texas Emissions Reduction Plan (TERP) and the Vehicle Inspection and Maintenance (VIM) program. TERP and VIM collect money from drivers upon inspection and registration renewal and then are supposed to use those funds for various air quality improvement programs. But, as Texas’ budget woes have increased in recent years, the state has begun holding on to this money as a way of artificially balancing the state budget. In the last biennial budget, Texas sat on $130 million in TERP money. This money should have been used to replace or upgrade heavy-duty diesel-powered trucks, machinery, train engines and construction vehicles.

Under the newly proposed section 185 fee rule, Texas would offset the penalty fees owed by major sources in the Houston area using unspent TERP and VIM money. If Texas doesn’t spend that money during the next year, it could credit it against its fee obligation again. In other words, Texas now has another incentive not to spend money it collects from Houston area drivers for pollution reduction programs: using money that you and I have paid to excuse big polluters from paying fees they owe under federal law.

TCEQ doesn’t even hide the fact that it intends to forgive polluters the entire amount they owe. After some back-of-the-envelope calculations in the rule package proposing the section 185 fee rule, TCEQ declares that “this [TERP and VIM] revenue could be used to fully offset the area's fee obligation and no fee would be assessed on major stationary sources for a particular calendar year.”

What’s more, this is only one way that Texas is thumbing its nose at federal law. The Clean Air Act requires that section 185 fee collection apply retroactively. Polluters owe fees back to 2008 – the year after the HGB area failed to attain the ozone standard. Texas gives another huge break to polluters by ignoring this federal mandate and declaring that it won’t collect fees until the year preceding the adoption date of its section 185 fee rules. That’s 2012 at the earliest, which means Texas is forgiving nearly half a billion dollars in fees that could be used for pollution reduction programs in our area while also holding on to over $100 million plus dollars that we have already paid and should also be used for programs that make our air cleaner.

And let’s not forget that if EPA rejects the Texas program, the federal government is then required to collect any fees that Texas fails to collect. With interest.

That’s money that could leave Texas forever and enrich the federal government – a prospect that should frighten even the most hardened federalists.

The proposed rule abounds with such bizarre and unnecessary measures. Federal law requires that section 185 fees are collected until the EPA finds that the HGB area has attained the one-hour ozone standard. TCEQ’s rule puts the fee program on hold as soon as it has air quality data that suggests that the area will attain. TCEQ has also defined baseline emissions in a way that is contrary to Clean Air Act requirements and allows sources to inflate their baselines by using outdated historical allowable emissions and including unauthorized maintenance/startup/shutdown emissions. This means that it is unlikely that very many sources will exceed 80% of their baselines and face significant fee obligations anyway.

Remember the TERP and VIM money that Texas is going to use to forgive section 185 fees? Money that Texas should already be spending on pollution reduction programs, but isn’t? TCEQ has decided that even though it won’t collect section 185 fees retroactively, it will go ahead and reach back to 2008 to credit TERP and VIM money against the 185 fee obligation.

Got that? Texas explicitly contradicts federal law to forgive polluters several years of retroactive penalty fees, but it uses the concept of retroactivity from that same law to conjure up a huge pile of money that it pretends already satisfies the penalty fee obligation.

Never mind that TERP and VIM money has already been collected for years. Or that the only reason we have so much of it on-hand is that we refuse to spend it on the very projects it was designed to fund. Or that there is nothing in federal law that allows us to credit anything against our section 185 fee obligation. TCEQ has created from whole cloth a bizarre method to forgive penalties that should be assessed against the major polluters who carry equal responsibility for the poor air quality that led to the imposition of those penalties in the first place by not spending money that residents of our region have been paying in order to clean up our air. We should all, in short, be completely outraged by this slight of hand.

If there were any doubt that TCEQ doesn’t intend to collect any fees under the section 185 program, we need only look at one final provision of the proposed rule. The rule says that polluters must pay fees within 30 days of receiving an invoice. What it doesn’t say, is when—or if—the invoices will be sent.

That’s right: there is nothing in TCEQ’s proposed rule that requires the Commission to send section 185 fee invoices.

You can learn more about TCEQ’s proposed section 185 fee rule here.

Texas Teen Tackles Air Pollution, Wins

This is a cross-post from Imatter, written by Eamon Umphress, a 16-year-old Texas resident.


Most 16-year-olds I know, including me, are interested in getting a job, a car, buying clothes and hanging out with friends, not saving the world. But I was given an opportunity to do just that.

In 2011, at age 15, I became part of a groundbreaking legal effort to protect the atmosphere for future generations, to ensure that we have a planet when we grow up. I became part of the iMatter/Our Children’s Trust legal action along with kids from 49 other states petitioning their state and federal government to protect the atmosphere from damage caused by greenhouse gas emissions.  We used an ancient legal concept called the “public trust doctrine.”  The doctrine is based on the idea that the government has an obligation to protect things that the community relies on, like water. But it has never been applied to the atmosphere before.

That’s because no one ever thought it needed protecting. Even in my short time on the planet, I’ve noticed a change in the climate. The hottest years in a century have happened in the last 10 years. Last summer was the hottest on record in Austin with over 90 days having temperatures above 100 degrees. And the projections for my beautiful green city are that by 2050, our climate will resemble the Sonoran desert.

But never could I have imagined that this lawsuit would have any real life impact. The idea even seemed a little far-fetched to me – suing the government to protect the atmosphere? I didn’t really give the effort much chance of success, but I thought it was important enough to give it a try, even if it seemed likely to fail. 



Part of what convinced me to do this was all the air alerts that warn old people and children to stay inside. It made me wonder if it was always like this. Did kids and grandparents always have to stay inside to protect their lungs? It was clear that something bad was happening to the air. . . you could even see the increasing amount of smog on the skyline. I was thinking someone had to do something about all the pollution going into the atmosphere, so I decided I would, because if I didn’t, who would? Someone had to do something. So I was really surprised when I learned that the judge said that the public trust doctrine must apply to all natural resources. The state had said it only applied to water, but the judge disagreed and broadened it.

The amazing thing is that the legal breakthrough happened in Texas, a state with a reputation for conservative judges and weak environmental laws. It really showed me that if you want something to happen, and you step up and make the effort, it just might.
A lot of kids my age feel like there isn't much they can do to make a difference on an individual scale. But I did. So you can too.

Imatter is a youth-led organization advocating for real solutions to climate change.

Pioneering Ozone Maps Empower Houston Residents

Matthew Tejada, Air Alliance Houston Executive Director

Guest Post By Matthew Tejada, Executive Director at Air Alliance Houston

Today Houston-area residents finally have a tool to help them take control over their own ozone exposure.

Air Alliance Houston, along with the University of Houston and the American Lung Association Plains Gulf Region, proudly launched The Houston Clean Air Network, a groundbreaking website featuring a first: real-time ozone maps.

This type of resource has been a dream of local public health and environmental experts for many years. The only way a person can protect their health from ozone was to totally avoid exposing their lungs to this dangerous pollutant, and now for Houston area residents there’s a resource that allows them to do exactly that.

Although individuals can check ozone values at monitor locations through various government agencies, the data available is not real-time and usually lags by 1.5 hours. This is important because ozone values can change quickly; thus, current data may not reflect actual exposure levels.

The new maps provide a unique visual representation of how the real-time ozone levels are moving throughout the Houston area. Displayed much like a weather radar map, the ozone “cloud” which the site displays animates movement and allows users to understand the temporal and spatial variation of ozone levels in their particular area.

The ozone moves in often surprising ways and sometimes neighborhoods that are close to each other have very different ozone readings. That information can allow sensitive groups to limit their exposure without giving up the outdoors all day during an ozone watch. Examples of how Houston residents could use this information include a runner deciding where to run – in Hermann Park or Terry Hershey Park – or a high school coach deciding whether practice should be held outside on the playing field or inside in the gym. Both decisions can now be made by accessing accurate, up-to-the-minute ozone information.

Ozone is a hazardous pollutant that poses a serious threat to human health and is found in consistently high concentrations in and around Houston. The health impacts that result from exposure to these high concentrations range from mild to severe, and place a burden on Houston’s economy both in productivity losses from adverse health effects and opportunity losses from individuals who choose to take their talents to other parts of the country with better air quality. With the introduction of this tool, individuals may now take control over their own exposure to ozone and reduce the associated health effects.

Sponsored by a three-year grant from the Houston Endowment, this valuable resource promises to change the way Houston-area residents view ozone and their individual exposure.

It is our sincere intention that this new site will benefit the thousands of people in the Houston area on a daily basis who suffer from a respiratory disease, as well as provide an important learning tool for teachers, students, parents, and children to understand how air quality affects their health.

Just as everyone checks the local weather to plan their daily activities, we hope that everyone will similarly check in with the Houston Clean Air Network to see current ozone levels and adjust their actions accordingly.
