Rustic or Dangerous? Why Keeping Treated Wood Materials Indoors Can be a Bad Idea

Telephone poles, cross ties, and other wood materials can be treated with chemicals that are dangerous to keep indoors.

Telephone poles, cross ties, and other wood materials can be treated with chemicals that are dangerous to keep indoors.

The below is a guest post from Mike Honeycutt, Director of Toxicology at the Texas Commission on Environmental Quality. Environmental Defense Fund appreciates the agency’s efforts to alert the public about a serious indoor air health issue.

At the Toxicology Division of the Texas Commission on Environmental Quality (TCEQ), we often receive phone calls from citizens with questions about various environmental concerns. Over the past few months, we received several calls asking if it is safe to use old wood materials inside homes, the most concerning of which came this past week from a realtor in the Dallas-Ft. Worth area. She had shown several homes recently that she suspected had used treated wood materials from telephone poles and cross ties as rustic accents. The realtor was concerned about using those materials inside where people could be exposed – and her intuition was spot-on. Read More »

A Neighborly Approach to Cleaning the Air in South Texas

Is that flare operating efficiently? Is it dangerous to my health? Whom do I ask? Whom do I tell? These are the types of questions an emerging workshop developed by EDF and RGISC aims to answer.

The U.S. Energy Information Administration recently ranked the Eagle Ford Shale play as the nation’s largest oil field. But with oil wells often comes wasted gas, something Texas knows all too well. A huge portion of the gas pulled from oil wells in the Eagle Ford is burned away— often sending damaging pollutants into our environment.

An investigative report published in the San Antonio Express-News last year found “the rate of Eagle Ford flaring was 10 times higher than the combined rate of the state's other oil fields.” The same researchers found that from 2009 through the first seven months of 2014 oil and gas operators in the Eagle Ford region wasted about 94 billion cubic feet of natural gas – roughly enough gas to serve the heating and cooking needs of all the homes in San Antonio over four years. Excessive or improper flaring is not only a waste of a valuable resource, but can also have harmful health effects and damage the environment.  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.

Sharing: How Lessons Learned in Kindergarten Apply to Freight Transportation

Sharing freight information can help build relationships with others.

Sharing freight information can help build relationships with others.

Leaders in the freight transportation industry may not realize it, but they probably learned an invaluable lesson for success when they were in kindergarten: learning to share is important.

After all, the interconnected world we live in today requires businesses to be accountable not only to shareholders and customers, but to other partners in the supply chain and to the communities living nearby. Whether disclosing the impacts to human health and the environment associated with goods movement, or implementing solutions to mitigate those impacts, sharing information can help build relationships with others, benefiting the overall supply chain.

New EPA Mapping Tool Sheds Light on Pollution Risk and Social Vulnerability

EPA's new mapping and screening tool will help advance environmental justice.

EPA's new mapping and screening tool will help advance environmental justice.

EPA is getting into the mapping game in a big way.

Just this week, they launched an environmental justice (EJ) mapping and screening tool called EJSCREEN, an online, publicly accessible index of environmental indicators based on location. It will be a tremendously helpful resource for the EJ movement.

In the past, concerned citizens, researchers, and advocates would access national databases individually without the ability to bring multiple sources of information together in one clear and consistent platform. EJSCREEN was created to address that issue. It’s a significant milestone that puts environmental and demographic data at your fingertips and empowers you to learn about your community. Read More »

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.
