A new study by Eduardo B. Olaguer of the Houston Advanced Research Center (HARC) purports to show that emissions from oil and gas operations will prevent nearby metropolitan areas — particularly Dallas-Fort Worth — from meeting federal ozone standards. Fortunately for people in the Metroplex, empirical data shows that such a conclusion is simply unsupported by the facts.
It’s worth noting, however, that the “ozone/smog issue” is a central plank in the anti-shale crowd’s agenda (part of its gradual shift of emphasis toward air quality). It began in earnest when Al “crucify them” Armendariz released a report in 2009 alleging that emissions of ozone precursors from oil and gas operations in the Barnett Shale were more than twice those emanating from mobile sources (i.e. cars and trucks). Given Dallas-Fort Worth’s well-known air quality problems, the study was cited far and wide.
The problem with Armendariz’s study — and other recent research suggesting harmful emissions from shale development — is that it relied on a modeling exercise that extrapolated an outlier of data into a broader trend. Proof of that has come from the Texas Commission on Environmental Quality (TCEQ), which has used state-of-the-art air quality monitors in the region to conclude not only that emissions from mobile sources are a larger contributor to smog, but that oil and gas operations have a minimal-at-worst impact (more on that below).
