This Thursday, the U.S. Environmental Protection Agency (EPA), will hold hearings across the country on the proposed updates to our national smog (ground-level ozone) standards from their current level of 75 parts per billion (ppb) to 65 to 70 ppb. Exacerbated by the combustion of fossil-fuel power plants and car exhaust, ground-level ozone is the single most widespread air pollutant in the United States and is linked to severe respiratory health outcomes. For an industrious and populous state like Texas, ozone poses a great threat to public health. In Texas, the hearing will take place from 9 a.m. to 7:30 p.m. local time at Arlington City Hall.
Does the proposal go far enough?
While EDF supports EPA’s proposal to strengthen these critical health protections, we believe that going even further, to 60 ppb, would provide the strongest protections for Americans and would be in line with what leading medical associations like the American Lung Association recommend. Read More
Last week, the U.S. Environmental Protection Agency (EPA) unveiled a proposal to update our national air quality standards for ground-level ozone, more commonly known as smog, from the current 75 parts per billion level to 65 to 70 parts per billion. Smog is a dangerous air pollutant linked to asthma attacks and other serious heart and lung diseases. That’s why EPA is also seeking comments on establishing a health standard of 60 parts per billion, a level that would provide the strongest public health protections for Americans according to scientific record. But despite the overwhelming scientific evidence of the health benefits of a more protective ozone standard, the Texas Commission on Environmental Quality (TCEQ), publicly opposes it.
Sixty to 70 parts per billion is the health-based range recommended by the Clean Air Scientific Advisory Committee, an independent panel of the nation’s leading scientists. The panel of scientists formed its recommendation based on an examination of bedrock scientific evidence and the requirement under the law to protect those most vulnerable.
In deconstructing TCEQ’s position on ozone, one can focus on a few key elements that stray from the mainstay of accepted public health principles:
Flaring in Eagle Ford Shale
The Texas Tribune recently published a piece debunking some of the science behind the Texas Commission on Environmental Quality’s (TCEQ) position on the national health standard for ozone – one of the most ubiquitous and harmful air pollutants on the planet. As outlined in the agency’s latest newsletter, TCEQ’s Director of Toxicology, Mike Honeycutt, questions the benefits of a stronger standard, even though public health experts across the country have been calling for a more protective standard for years. What’s more disappointing than the agency’s apparent anti-health position, however, is the lack of attention to other legitimate air pollution issues in Texas.
It would seem that the agency must have a surplus of staff, as well as unlimited resources to establish such an aggressive position on a standard that hasn’t been proposed yet. The reality is that there are so many more important things that the agency could and should be doing to serve and protect Texas citizens from real air pollution threats, including: Read More

Earlier this year, close to 20 Texas counties received a grade of "F" from the American Lung Association for ozone pollution (up from 15 counties in 2013). Ozone is one of the most ubiquitous and harmful air pollutants on the planet and has been linked to premature deaths, increased asthma attacks and other severe respiratory illnesses, as well as increased emergency room and hospital admissions. And it poses an especially serious risk to children, seniors and those with lung diseases like asthma and bronchitis.
If realized, a stronger public health standard for ozone would prevent up to 12,000 premature deaths, avoid up to 21,000 hospitalizations and provide $100 billion in associated economic benefits.
Why then are Texas officials fighting tooth and nail against it?
U.S. Rep. Randy Weber, R-Pearland, joined by fellow Texas Republican Reps. Lamar Smith of San Antonio, Pete Sessions of Dallas, Blake Farenthold of Corpus Christi, Kevin Brady of the Houston area, John Carter of Round Rock and Sam Johnson of Richardson, introduced a bill that would serve to obstruct health protections promised in the Clean Air Act. This bill would deny Texas cities, the state and the country from their right to strong public health protections. Read More

Last 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.

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

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
