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

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 »

Will Texas Step Up to the Plate on Energy Efficiency and Carbon Pollution Standards?

rp_Kate-Zerrenner-200x300.jpgA couple of weeks ago, I wrote about energy efficiency and the Clean Air Act section 111(d) provisions in anticipation of the SPEER Second Annual Summit, a gathering of top energy efficiency industry leaders from Texas and Oklahoma. At the Summit, I co-led a session on Environmental Protection Agency’s (EPA’s) push to regulate power plant emissions. Session attendees agreed that Texas would be an unlikely leader in developing innovative ways to comply with carbon pollution standards for existing power plants.

This is a missed opportunity on Texas’ part, as states will get the first crack at drafting plans to comply with new federal standards. This is an important opportunity because individual states are in the best position to craft frameworks that enable maximum flexibility and are appropriately tailored to local circumstances. So, this begs the question: is there an alternative, more constructive path that is most beneficial to Texas?  Read More »

Today marks the 20th anniversary of the Presidential Executive Order calling for Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations, which prompts us to ask: What would the environmental movement in the United States look like if there were genuine cross-pollination, collaboration, and feedback between large, national-scale organizations and locally-based, environmental justice organizations?

Last week, we at EDF had a chance to experience a small glimpse of what this would be like when we delivered comments at EPA’s public hearing on new carbon pollution limits for new power plants alongside other Latino representatives and environmental activists. Among these activists was Adrian Shelley, Executive Director of Air Alliance Houston.

Air Alliance Houston (AAH) is the region’s leading air quality and public health non-profit, working in the most diverse city in the United States. With a population that is more than one-third Latino, Houston is a majority-minority city seated in Harris County, the fastest-growing county in the country. It’s also ground zero for the environmental justice movement. The distribution of health risks is unequal, as air pollutants that pose a definite risk to human health are found in greater numbers in several East Houston neighborhoods adjacent to the Houston Ship Channel.

Time for Texas to Work With EPA To Secure Cleaner Air For All Texans

Elena QuoteLast Wednesday, I traveled to Washington D.C. to testify at a House Science, Space, and Technology hearing entitled Examining the Science of EPA Overreach: A Case Study in Texas. It was my first time testifying on Capitol Hill and I was grateful for the opportunity to connect with some of our Texas lawmakers on issues concerning the relationship between the Environmental Protection Agency (EPA) and Texas.

One item of discussion focused on the greenhouse gas permitting authority in the state and the fact that Texas’ legal actions have thwarted industrial facilities in the state from conducting business. A recent article in the Texas Tribune, titled “Anti-Regulation Politics May Have Hurt Energy Industry,” highlights the burden that a dual permitting process places on businesses seeking greenhouse gas permits.

The process, which requires industrial facilities, such as power plants and refineries, to apply to Texas Commission on Environmental Quality (TCEQ) for criteria air pollutants permits and separately to EPA for greenhouse gas permits, has proved onerous for industry. In the article, the Texas Pipeline Association says, “more than 50 planned projects since early 2011 have been significantly delayed by the [Texas] permitting process, putting 48,000 jobs at risk.” Read More »

Energy Efficiency Is Key to Achieving Carbon Pollution Standard

Kate ZerrennerRight now, there are no limits on carbon pollution from power plants, even though these facilities were responsible for  roughly 40 percent of all U.S. carbon dioxide (CO2) emissions in 2012.

That’s why the Environmental Protection Agency (EPA) is crafting greenhouse gas (GHG) regulations for new fossil fuel-fired power plants by setting a limit on how much CO2 the plants can emit. Later this year, EPA will issue proposed CO2 “emission guidelines” for existing fossil fuel-fired power plants using various Clean Air Act tools to protect human health and to clean up our air.

To achieve significant and cost-effective emission reductions from existing power plants, EPA should look to leading states that are already implementing successful measures to reduce emissions. These measures include investing in renewable energy, harvesting energy efficiency, and utilizing more efficient and lower-emitting fossil fuel-fired units. Read More »

Why Do Latinos Support Action on Climate Change?

Source: Mom's Clean Air Force

Your abuela or your friend’s abuela may not mention “carbon pollution” or “greenhouse gas emissions” much, but don’t let that fool you into thinking Hispanics are not aware of or unconcerned with what is happening to our planet. In fact, polling confirms that Latinos overwhelmingly support action to curb climate change. A recent poll for the Natural Resources Defense Council by Latino Decisions shows that 80 percent of Latino voters somewhat-to-strongly favor Presidential action to fight carbon pollution.

Why? Family values.

The reasons are similar to those held by many interested in protecting the planet for future generations. The poll proves that Latinos are concerned about air quality, health effects of a worsening environment and teaching a cultural legacy of environmental stewardship and conservation. Read More »

Haze over Dallas Area

Last week, EDF took one more step toward protecting Texans from harmful levels of ozone pollution that have afflicted the state for far too long.

Ozone pollution, better known as “smog,” is one of the most severe and persistent public health problems affecting Texans.  Smog causes a range of health issues — including aggravation of asthma and other respiratory illnesses, decreased lung function, increased hospital and emergency room visits for respiratory conditions — and it is associated with premature mortality in urban areas.

According to the American Lung Association (ALA), Dallas-Fort Worth is the eighth most affected area in the country for smog.  ALA estimates the city is home to millions of people who are sensitive to ozone-related health problems — including 1.6 million people suffering cardiovascular disease; nearly 1.9 million children; nearly 650,000 elderly residents; and over 520,000 people with asthma.

Why Doesn’t Texas Want Clean Air?

Para un breve resumen de la crítica de Texas contra CSAPR en español, haga clic aquí.

Today the U.S. Supreme Court and the U.S. Court of Appeals for the D.C. Circuit heard arguments over two critically important clean air protections – the Cross-State Air Pollution Rule and the Standards for Mercury and Air Toxics. Texas has fought tooth and nail against both of these major pollution protections – protections that together have been estimated to prevent up to 45,000 deaths, 19,700 heart attacks and 530,000 asthma attacks.

Why are These Rules Important to Texas?

Air pollution from Texas' coal plants is, like many things in Texas, giant sized. Texas power plants collectively are the nation’s largest emitter of nitrogen oxides (NOx), and the second largest emitter of sulfur dioxide (SO2). Both pollutants are components of smog and are harmful to human health.

The Cross-State Air Pollution Rule (CSPAR), which applies to the eastern U.S, is of particular interest to Texas, not only because it helps control emissions within the state, but also because it helps protect the state from air pollution blowing in from neighboring states. CSAPR provides for upwind states to be good neighbors and protect downwind communities from harmful particulate matter and smog-forming pollution discharged from power plant smokestacks. Read More »

The Irony of Texas Taking Over GHG Permitting Authority

This blog post was co-written by Adrian Shelley, Executive Director of Air Alliance Houston.

Last week, the Texas Commission on Environmental Quality (TCEQ) held its only public hearing regarding the agency’s proposed plan to take over greenhouse gas (GHG) permitting authority from the Environmental Protection Agency (EPA). Neither the TCEQ commissioners nor the executive director attended the hearing.

TCEQ’s move to issue GHG permits is quite a departure from the extensive actions the Texas government has taken NOT to regulate greenhouse gases in the state. In fact, in a letter dated August 2, 2010 to then EPA Administrator Lisa Jackson, Texas Attorney General Greg Abbott and TCEQ Chairman Bryan Shaw used aggressive and robust language, declaring that:

“On behalf of the State of Texas, we write to inform you that Texas has neither the authority nor the intention of interpreting, ignoring, or amending its laws in order to compel the permitting of greenhouse gas emissions.” Read More »
