A new study accepted for publication in Environmental Science & Technology takes a close look at the amount of certain air pollutants in the Barnett Shale, a booming oil and gas region in North Texas. Using public monitoring data from 2010-2011, researchers from the University of Texas at Austin compared air pollution levels measured at a monitor surrounded by oil and gas operations to the levels that would be expected based on available emission estimates. The result brings to light that the emissions inventory from the Texas Commission on Environmental Quality (TCEQ) for the Barnett Shale does not add up to the observations.
There are numerous air pollutants that can be emitted by oil and natural gas development. Depending on the local composition of the produced gas, emissions can often include volatile organic compounds (VOC, such as propane, butane, pentane, etc.) that contribute to the formation of ground-level ozone (also known as smog), and toxic air pollutants like benzene and hexane that are directly hazardous to human health. Methane, the primary ingredient in natural gas and a greenhouse gas catching lots of attention these days, is another powerful pollutant associated with these operations. Unlike the pollutants listed above, methane directly affects the health of our climate rather than human health. Fortunately, available technologies designed to capture methane are also effective in reducing these other pollutants. However, methane controls alone may not ensure that local air quality concerns are addressed – these require special attention. Read More

We know that ozone pollution is a public health threat in Houston. Now a study by the U.S. Environmental Protection Agency suggests that threat is greater than previously thought. As a result, the ozone standard is likely to be lowered by the end of the year. Houston has never met an ozone standard, but it is time for us to get serious about protecting our health.
The Environmental Protection Agency has been considering lowering the standard since 2008, when President George W. Bush's EPA revised it to 75 parts per billion. That revision defied an EPA recommendation for a standard as low as 70 parts per billion. Now the agency recommends that 60 parts per billion may be needed to protect public health.
Ozone, unlike other air pollutants, isn't restricted to certain parts of Houston. It's found everywhere, and it causes asthma attacks, heart disease and even early death. In the Houston region, 6 million people are at risk.
It is the responsibility of the Texas Commission on Environmental Quality to bring ozone down to healthy levels. In reacting to the EPA's new findings, the TCEQ focuses not on the need to protect public health, but on the regulatory burden of reducing air pollution. The TCEQ is already attacking the science behind the new study. TCEQ Chief Toxicologist Michael Honeycutt has questioned even the concept of an eight-hour ozone standard, suggesting in a Houston Chronicle story that it might be "more appropriate" to return to a one-hour standard, as the EPA had in the 1970s.

Haze over Dallas Area
Last week, EDF took one more step toward protecting Texans from harmful levels of ozone pollution that have afflicted the state for far too long.
Ozone pollution, better known as “smog,” is one of the most severe and persistent public health problems affecting Texans. Smog causes a range of health issues — including aggravation of asthma and other respiratory illnesses, decreased lung function, increased hospital and emergency room visits for respiratory conditions — and it is associated with premature mortality in urban areas.
According to the American Lung Association (ALA), Dallas-Fort Worth is the eighth most affected area in the country for smog. ALA estimates the city is home to millions of people who are sensitive to ozone-related health problems — including 1.6 million people suffering cardiovascular disease; nearly 1.9 million children; nearly 650,000 elderly residents; and over 520,000 people with asthma.

Recently, the Houston Chronicle published an article showing that over 80,000 schoolchildren at 127 schools are frequently exposed to air pollution due to their proximity to busy roadways. Houston, in particular, is vulnerable to the formation of unhealthy air pollution, given the city is home to one of the busiest ports in the country and some of the busiest roadways, and emissions from all those vehicles tend to pool around the streets locals use most. But what’s critical to note is that exposure to this kind of pollution is especially harmful for our young ones, as children breathe in more air per pound of body weight than adults. Now, with these staggering figures, it’s clear that something must be done to protect Houston children from the dangers of vehicle pollution.
In total, 127 Houston-area schools were found to be located within 200 meters of a roadway, the distance within which traffic-related pollution is most potent. The accumulation of these emissions, which contain nitrous oxides (NOx) and volatile organic compounds (VOCs), form ozone pollution under the right conditions—usually on warm, sunny days. With no shortage of vehicles emissions or sunlight, the city is definitely a hot spot for ozone pollution and Houstonians are faced with increased health risks. Read More

As we have highlighted before, EPA’s recent actions regarding storage tank standards is of particular interest to Texas. In 2009 alone, there were 6,120 storage tanks built in Texas large enough to be subject to EPA’s standards. The standards will apply only to new tanks. Since the number of new tanks is related to the number of existing wells, and Texas accounts for approximately 23% of new oil wells and 33% of new gas wells drilled in the U.S. (far greater than any other state), Texas is likely to account for a large share of the country’s new storage tanks. From a health standpoint, this rule preserves important protections for Texans, but much more remains to be done. Many counties in Texas fail to meet health based air quality standards. EPA needs to fortify thoughtful rules that place public health above all else, so that Texans (and many others) can breathe safe, healthy air that is free of ozone and other harmful contaminants.
A new year may be upon us, but – unfortunately – some members of the oil and gas industry would prefer we roll back the clock on common sense, long-overdue emission standards for oil and gas equipment.
Oil and natural gas production continues to expand rapidly in the United States – and with it the potential for emissions of climate-destabilizing pollutants (especially methane), smog-forming compounds and carcinogenic substances, such as benzene. We urgently need rigorous national standards that comprehensively address the full suite of pollutants from oil and gas facilities, protect public health and the environment and conserve needless waste of our nation’s natural resources.

As we come to the end of another year, we look back on the progress that has been made to improve Texas’ air quality. Our work is especially important in Texas. Ozone pollution in the state’s largest cities routinely spikes above healthy levels, and Texas leads the nation in annual carbon emissions.
Throughout 2013, my fellow bloggers and I tracked the critical progress made towards cleaner air in Texas. Texas experienced a handful of victories and a handful of losses. To summarize the year, I’ll discuss a few of the areas where we made progress, and a few of the areas where there is still more work to do.
Progress Toward Smart Power and Clean Air
Over the past year, Texas wind power continued its promising positive trend, thanks in part to the state’s forward-looking decision to build new high-capacity electricity transmission lines linking the windy plains of West Texas with the state’s cities. The Competitive Renewable Energy Zone (CREZ) transmission project was approved by the state in 2008, and the new power lines are set to come online in a few weeks. The new power lines can carry 18,500 megawatts of electricity—enough to power millions of homes. The CREZ lines will help ensure Texas wind energy continues to expand, offsetting electricity produced from fossil-fuel power plants and reducing pollution. Read More

Para un breve resumen de la crítica de Texas contra CSAPR en español, haga clic aquí.
Today the U.S. Supreme Court and the U.S. Court of Appeals for the D.C. Circuit heard arguments over two critically important clean air protections – the Cross-State Air Pollution Rule and the Standards for Mercury and Air Toxics. Texas has fought tooth and nail against both of these major pollution protections – protections that together have been estimated to prevent up to 45,000 deaths, 19,700 heart attacks and 530,000 asthma attacks.
Why are These Rules Important to Texas?
Air pollution from Texas' coal plants is, like many things in Texas, giant sized. Texas power plants collectively are the nation’s largest emitter of nitrogen oxides (NOx), and the second largest emitter of sulfur dioxide (SO2). Both pollutants are components of smog and are harmful to human health.
The Cross-State Air Pollution Rule (CSPAR), which applies to the eastern U.S, is of particular interest to Texas, not only because it helps control emissions within the state, but also because it helps protect the state from air pollution blowing in from neighboring states. CSAPR provides for upwind states to be good neighbors and protect downwind communities from harmful particulate matter and smog-forming pollution discharged from power plant smokestacks. Read More
October 31 marked the official end of ozone season in Texas. Ozone pollution, commonly known as smog, forms when compounds found in fossil fuel emissions react with sunlight. Ozone is a serious health concern for Texans, as excess exposure to ozone has been linked to a number of detrimental health effects, including asthma, heart attacks and even cancer.
Unfortunately, for many Texas cities, the combination of sunny days and crowded highways led to consistent violations of the standard over the course of this ozone season, and on a few days outside the season.
This year’s air quality measurements from the Houston region demonstrate that ozone pollution surpassed EPA’s health-based standard during 24 separate 8-hour intervals in 2013. Last year, the same air monitoring stations recorded 37 ozone violation days. Houston saw the highest ozone levels across the state, but Dallas and San Antonio followed closely behind. The worst days for both Houston and Dallas came when ozone peaked at 100 ppb—a level considered unsafe for healthy children and adults to have prolonged outdoor activities. Read More

Last week, the U.S. Environmental Protection Agency (EPA) Region VI, representing Texas and surrounding states, announced that Houston was on track to meet the 1997 federal health standard for ozone within the next five years. Of course, I am and have been supportive of the multitude of efforts deployed and enforced to reduce ozone levels in Houston over the years. At the same time, I am concerned that the recent announcement may create a public perception of Houston as out of the weeds.
The truth is that the 1997 standard has been found to be woefully inadequate to protect human health from the harms of ozone, which include, but are not limited to, asthma, bronchitis and cancer. The 1997 standard of 84 parts per billion (ppb) was revised in 2008 to a standard of 75ppb. Even this standard of 75ppb, however, has been criticized for failing to provide adequate public health protection. In addition, a closer look at ozone Design Values (a wonky term for the three-year average of the four highest days of eight-hour ozone concentration in each year) in Houston over the last five years suggests that the region may have reached a plateau in terms of reducing ozone.

Last month, I highlighted some Texas cities working to educate their citizens on the importance of air quality. Because air pollution is a persistent problem throughout Texas, the state’s largest cities all maintain websites focusing on ways to mitigate emissions and take precautions when air pollution reaches concentrations considered to be unhealthy. While these informational campaigns promote voluntary reductions in emissions, they aren’t sufficient to keep air quality under control.
Regional coalitions all over the state are at the front line forging needed partnerships to achieve major emissions reductions and improve the quality of air across Texas. The following are a few organizing leading the effort: Read More
