Texas Clean Air Matters

In San Antonio, Cleaner Air May Be on the Horizon

For many years, San Antonio’s air quality has been at a tipping point. With smog levels that just narrowly hovered beneath national limits for ozone pollution, the city is currently in competition for having some of the worst smog levels in Texas.

Ground-level ozone can cause asthma attacks and other illnesses—which means the state of San Antonio’s air quality is putting public health at risk.  That’s about to change thanks to new Environmental Protection Agency (EPA) standards that set stronger limits on ozone levels—pushing smog-challenged cities like San Antonio to take action and clean up the air.   Read More »

Air Quality Poses Challenges and Opportunities for San Antonio’s New Mayor

SONY DSCTexans don’t always associate clean air with major urban areas, and for good reason. The heavy industrial activity, electric power plants, and vehicular traffic in big cities all combine to create ground level ozone, commonly known as smog. Increased ozone and smog has known negative impacts on human health, including causing asthma  attacks and other respiratory problems. The Environmental Protection Agency (EPA) regulates ozone and sets guidelines for when a city is in compliance with air quality standards. Currently, San Antonio is technically in compliance with EPA ozone standards, but only by a quirk in how the agency’s compliance timelines work. A closer look actually shows the city has the second worst air quality of any urban area in Texas – second only to Dallas/Fort Worth.

The correlation between ozone and public health has spurred EPA to revise and strengthen its national ozone standards. If San Antonio continues with business as usual, it’s clear local air quality and public health will continue to suffer, and San Antonio will be officially designated as non-compliant with EPA standards.

Reducing Drilling Pollution—Wyoming Did It, No Big Deal. Will Texas?

ozonegraphThe technological advances that led to the “shale revolution” have undoubtedly had a large economic impact on the Texas economy – something state leaders and the oil and gas industry are never shy about pointing out. But the impact drilling has on air quality and public health, that’s something energy-friendly Texas has not been so quick to recognize.

When not managed responsibly, drilling operations can contribute to the formation of ozone, also commonly known as smog. At certain concentrations, this pollution can trigger asthma attacks and cause other severe respiratory illnesses.

San Antonio is one place that’s seeing the clear connection between drilling and lower air quality, thanks to increased drilling just south of the city from the Eagle Ford Shale region. Before 2008, ozone levels in San Antonio had been steadily dropping, but when the shale revolution hit and drilling increased, regional ozone readings started going up.  In fact, based on air quality monitor readings from the last three years, San Antonio’s air quality is the 2nd worst in the state.  This correlation between drilling and ozone levels has been documented by The University of Texas and the Alamo Area Council of Governments, both of which concluded oil and gas activity in the Eagle Ford Shale is materially impacting ozone levels in San Antonio.
