Estimated Distribution of Benzene Annual Concentration, Based on Retrieved Primary Source Location and Wind Direction Frequency

One year ago this week, EDF, along with Air Alliance Houston (AAH), submitted comments to the Texas Commission on Environmental Quality (TCEQ) regarding its proposal to remove Texas City from the state’s Air Pollutant Watch List (APWL). We believe the agency’s proposal to remove Texas City from the Watch List for benzene and hydrogen sulfide, two lethal air pollutants, was premature.

To date, the TCEQ has not addressed our public comments on the Texas City proposal, though it has found time to analyze and recommend two other areas for removal from the APWL. We believe that this reflects TCEQ’s misplaced priorities. The agency seems to prefer removing areas from the APWL — thereby lifting a burden on industry— rather than ensuring adequate protection for public health. Read More »

Early this week, the White House released the third National Climate Assessment (NCA). What’s the main take away? That Americans are already feeling the effects of climate change.

The NCA, authored by 300 experts and guided by a 60-member Federal Advisory Committee, analyzes the best available data in the U.S. on the observed and future impacts of climate change, and organizes its findings for specific sectors and regions. Texas falls under the Great Plains region and the state’s bustling economy includes many industries that will be affected by a changing climate, such as agriculture and energy.  Our water, ecosystems, transportation, and more will also be affected. It is clear from this report that heat and drought will intensify in Texas, putting energy, agriculture, and human health at increased risk. State leaders need to enact policies now to protect us and our livelihoods.  Read More »

State of the Air 2014: 19 Texas Counties Continue to Struggle with Ozone Pollution

State of the Air ALA 2014Last week, the American Lung Association (ALA) released its annual State of the Air report, which reviews air pollution data compiled by the Environmental Protection Agency (EPA) for two of the most hazardous types of air pollution: ozone and particulate matter.

Overall findings indicate that ozone pollution increased in metropolitan areas throughout the nation due to warmer temperatures. At the same time, fine particle pollution, or soot as it is most commonly called, decreased due to fewer emissions from coal-fired power plants and wider use of cleaner fuels and engines.

For a primer on ozone pollution and health, read here.

Unfortunately, Houston crept up in the rankings to 6th most polluted for ozone in the country (up from 7th last year).  And with the exception of Dallas-Fort Worth, other cities in Texas followed the national ozone trend, reporting a greater number of unhealthy days this year. Texas cities did fare better on soot pollution, although a notable exception was El Paso, which was one of only five U.S. cities that saw an increase in year-round pollution. Read More »

Ten Years of SmartWay: Nearly Seventeen Billion Saved in Fuel Costs and Counting

EPA SmartWay 10This year Environmental Protection Agency (EPA) is celebrating the 10 year anniversary of its SmartWay program, a voluntary program created to help freight companies move more goods across more miles without the extra emissions. Texas boasts more than 180 SmartWay partners and affiliates, including Dell, AT&T, and BNSF Railway to name a few, that have made a commitment to improve fuel efficiency, reduce diesel consumption, and increase sustainability along transportation routes. These pledges have turned into action as SmartWay partners across the nation have saved $16.8 billion in fuel costs, reduced oil consumption by more than 120.7 million barrels, and reduced 51.6 million metric tons of carbon dioxide across the nation – that’s equivalent to taking over 10 million cars off the road every year.

Supreme Court Victory Brings Clean Air to Texas despite Challenges from State

Today marks the second in a series of clean air court victories that are nothing less than triumphant for air quality and health in Texas. The U.S. Supreme Court ruled today in favor of Environmental Protection Agency’s (EPA’s) Cross-State Air Pollution Rule (CSAPR), a clean air standard that will protect the health of Americans across 28 Eastern states, including Texas, from the harmful air pollution emitted by distant power plants that moves across state borders. For Texas, the nation’s number one emitter of nitrogen oxides (NOx) and the number two emitter of sulfur dioxide (SO2), these vital clean air protections will safeguard the health of our children and elderly and revoke the coal industry’s free license to pollute without limitation, shielding neighboring states from lethal particulate matter and smog-forming pollution. Not to mention, today’s decision (once again) proves that Texas Attorney General Greg Abbott’s crusade to dismantle EPA’s common sense standards is fruitless, wastes taxpayer’s dollars, and jeopardizes the public health of all  Texans.

Much like the life-saving Mercury and Air Toxics Standards (MATS), upheld earlier this month by the U.S. Court of Appeals, CSAPR will reduce sulfur dioxide levels from power plants in eastern power plants by 73% and nitrogen oxide levels by 54% from 2005 levels. The emissions reductions from CSAPR alone will save up to 1,704 lives in Texas and provide the state with $5.8 to $14 billion annually in health benefits starting in 2014. Despite these substantial health benefits, the State of Texas challenged the rule to prevent a handful of coal plants from switching to low-sulfur coal, increasing scrubber efficiency, or installing readily-available pollution-control technology.

As bluebonnets dot the Texas highways signaling the arrival of spring and summer, concerns about ozone pollution also begin to surface. March 1 marks the official start of ozone season in the Dallas Metroplex and in Greater Houston. Other metro areas, including Austin and San Antonio, mark April 1 as their start date. Ozone forecast season ends for most areas on October 31, but in Houston it lasts through November 30. Ozone season is nothing to celebrate, but this primer can help get you up to speed on the basics of ozone pollution and what you can do to improve air quality and protect the health of your family.

What is ozone? Ground-level ozone is the main component of smog and is the single most widespread air pollutant in the United States. Ozone pollution forms when nitrogen oxides and volatile organic compounds (primarily released from combustion of fossil fuels, like car exhaust) react with heat and sunlight. Texas’ combination of heavy industrial activity, hot summers, and millions of cars on the road increases the potential for generation of harmful levels of ozone. Read More »

Why Latinos Are Disproportionately Affected by Asthma, and What We Can Do

This post was co-authored by Lucía Oliva Hen­nelly, EDF's Tom Graff Diversity fellow, Rachel Shaffer, EDF's Research Assistant, and Declan Kingland, National Health Programs Coordinator for the League of United Latin American Citizens.

Today in the United States, Latinos are three times more likely to die from asthma than other racial or ethnic groups. Latino children are 40 percent more likely to die from asthma than non-Latino whites, and nearly 1 in 10 Latino children under the age of 18 suffer from this chronic respiratory illness. Addressing the dangerous indoor and outdoor air pollution that is linked to asthma is critical for the health of Latino communities – and for all Americans.

Socio-economics

Latinos are one of the poorest demographics in the United States, with roughly 1 in 4 Latinos living under the poverty level. Many Latinos also face challenges due to limited English-language proficiency, and in some cases, low levels of education. These issues can lead Latinos, particularly new immigrants, to low-paying jobs, often in the fields of agriculture, construction, and service. Too often, these jobs expose workers to serious respiratory hazards from both indoor and outdoor air pollution, yet they frequently provide no healthcare benefits. For example, the toxic chemical formaldehyde, which is linked to asthma, can be found in glues, insulation, and wood products to which construction workers are disproportionately exposed. Asthma-related toxics can also be found in paints, cleaning products, carpets, and foam cushions. Read More »

Air Emissions from Eagle Ford Oil and Gas Activity Expected to Quadruple over next Four Years

Well site located in Eagle Ford Shale play

Well site located in Eagle Ford Shale play

Late last week, the Alamo Area Council of Governments (AACOG) released a report outlining emission projections from oil and gas activity in the Eagle Ford Shale play, the most active drilling area in the country right now. Under the moderate drilling activity scenario, projections of air pollutants are expected to quadruple in the next four years. Even though this seems like a staggering prediction, it is likely an underestimation, given certain emissions are not accounted for in the inventory.

What does the report say?

The report assesses the emissions from oil and gas activity in the Eagle Ford Shale play and projects air pollution under three different development scenarios: low, moderate, and aggressive. Projections over the next several years indicate that we can expect substantial increases in smog-forming nitrogen oxide emissions (NOx), volatile organic compounds (VOCs), and carbon monoxide.

A New Study Points to the Need for Improved Air Monitoring in Texas

Source: Dallas Observer

Source: Dallas Observer

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 »

Every day, countless heavy duty diesel trucks and oil-burning cargo ships move tons of goods through U.S. ports, adding pollution to urban areas that may be suffering from poor air quality. As many ports across the nation are undergoing expansion projects and increased throughput of goods, environmental concerns have become a high profile issue. With the right tools and collaboration among stakeholders, however, ports have significant opportunity to lessen their environmental impact and improve local air quality.

Thankfully, the U.S. Environmental Protection Agency (EPA) will host a National Port Stakeholders Summit next week, in Baltimore, Maryland to address challenges and advance sustainability at ports. The summit invites experts and stakeholders to share expertise, ideas, and actions to reduce the ecological impact of port operations. Read More »
