Bexar Not Among 18 Texas Counties Failing to Meet EPA Ozone Standard

A layer of smog clouds the San Antonio skyline.

Bexar County is not one of 18 Texas counties that the U.S. Environmental Protection Agency reported it will designate in “nonattainment” with federal ozone standards. All 18 noncompliant counties are in the Houston and Dallas/Fort Worth metro areas, according to a Dec. 22 letter from the EPA to Texas Gov. Greg Abbott.

In the letter, Samuel Coleman, the EPA’s deputy regional administrator in Dallas, wrote that the federal agency intends to designate all other Texas counties in compliance with federal ozone standards, although it did not specifically mention Bexar County.

“I sincerely appreciate the EPA analyzing the unique circumstances that surround San Antonio,” said Diane Rath, executive director of the Alamo Area Council of Governments (AACOG). “In this region, only 32 percent of ozone is produced here; 68 percent comes from outside. The EPA assessed and took into consideration those background ozone levels and the influence of foreign transport” on the region’s ozone level.

Some local officials had feared that Bexar County would be placed in the nonattainment category by the EPA because it was excluded from the list of counties the agency in November classified as compliant with federal air quality standards.

Rath said if public and partners uphold their “ongoing commitment to the health of region, [Bexar County] will be  in compliance by 2020 and well under the limit by 2023.”

The EPA did not return the Rivard Report’s requests for comment before publication deadline.

In an email to the Rivard Report, Brian McGovern, media relations specialist with the Texas Commission on Environmental Quality, said the organization “is pleased that the EPA has … deferred a designation recommendation for Bexar County at this time.”

The list of nonattainment counties includes Dallas, Tarrant, Harris, and Galveston counties – home to two of the state’s largest cities, Houston and Dallas – as well as counties near those cities, including Collin and Denton near Dallas, and Brazoria and Fort Bend near Houston.

The EPA changed the primary eight-hour ozone standard from 75 parts per billion to 70 in 2015 to “provide increased protection of public health,” the letter to Abbott states.

The San Antonio area’s 74 parts per billion average between 2015 and 2017 violates the EPA’s 2015 standard, according to data compiled by the AACOG.

“We’ve made significant progress,” Rath said. “Despite a population increase of more than one million, we’ve dropped 20 points since 2003 – all through voluntary measures by both private and public partners.”

Those measures, Rath said, include the City’s anti-idling ordinance that prohibits large trucks and buses from idling for more than five minutes, CPS Energy closing down the Deely power plant and investing in more efficient energy, VIA Metropolitan Transit converting its fleet to compressed natural gas buses, and the private sector investing in up-to-date technology that reduces emissions, among others.

“Without exorbitant expense, we are producing significant results,” she said.

Ground-level ozone forms when certain man-made and natural chemical pollutants directly interact with the sun’s ultraviolet rays. A key component of smog, ozone is unhealthy to breathe as it may irritate or damage lungs.

A nonattainment status could prompt a slate of costly measures for the public and private sectors, including restrictions on manufacturing company relocation and expansion, project delays, and lost gross regional product, according to a report commissioned by the AACOG. Economic losses in the San Antonio Metropolitan Statistical Area due to marginal nonattainment could cost upward of $3.2 billion, the study found.

The first local analysis addressing ground-level ozone pollution in San Antonio, commissioned by the City’s Office of Sustainability, revealed that the city would see an additional 19 respiratory deaths per year if ozone levels were to rise to 80 parts per billion, costing the local economy $170 million. If ozone levels were to fall below 68 parts per billion, the study found, it would avoid 24 deaths annually and save a total of $220 million.

“We need to improve our air quality to improve the health of vulnerable populations,” Rath said. “That’s what this is all about.”

  1. Congratulations to San Antonio for meeting ozone attainment goals. Keep expanding anti idling programs such as right turn on red, turn on blinking yellow arrows, and other ways to keep cars moving. Keep expanding VIA Bus initiatives and ridership. Keep making the over 200 miles of nature trails in San Antonio accessible, attractive, and safe for walking and biking to destinations. Provide ideas to trail map websites, such as NatureTrailMaps.net.

  2. It’s good that we’re making progress but we could be doing much better. We need to further promote the use of electric cars and biofuels. There is a high percentage of FlexFuel cars which can run on E85 ethanol blend fuel in this area, but unfortunately, most people who own them never use E85. I believe the primary reason is that most of the area gas stations that sell E85 are charging way too much, basically price gouging. I understand that any business deserves to make a profit, but our air quality will only get better if everyone is willing to give a little to help achieve the common goal. Additionally, we need more businesses to cooperate by providing electric car charging for employees. The two most important places to be able to charge an electric car are at home and at work.
    My family is doing our part, we have invested in two electric cars which we use for almost all of our daily transportation. We also have one FlexFuel car in which we use exclusively E85 fuel, however, that car is only used about three or four times a year for long distance travel. We also bicycle or walk where it is practical.

  3. Such an endorsement from an EPA headed by one of the fossil fuels industry’s greatest champion deniers of Global Warming is probably bad news for public health. It may save SA money by avoiding loss of federal funding, but may end up costing much more in public health treatments, workday losses and school absences. This EOA rating can be compared to a drop in the number speed violations, due to raising the speed limit from 75 to 85 mph, or to a drop in arrests for the use of marijuana due to the legalization of marijuana. Can we imagine what the impact on human health and safety would be if a City Council ordered the Police Department to stop arresting people for shootouts on public streets because it would cut down on their workloads and paperwork and save the city money in overtime pay?? It might save money in that category, but it would surely increase costs in emergency medical responses and hospital ER costs. Not to mention the list of human life, which is priceless. Let us not deceive ourselves by simply legalizing denial of reality. I prefer an EPA that will honor and fulfill its original mission. In the long run, it is better for the public health and the economy, both.

  4. No Diane Rath what it’s all really about is you a Chris Schubert (Vulcan’s lawyer) dismatling the AACOG’s air Quality committee. Now the industries control air quality decisions so the concrete industry won’t have to deal with an of those pesky regulations. The TCEQ funding the AACOG’s study full of flaws only solidifies the conflict of interests. I thought Rath was supposed to fix the past corruption within the AACOG?
