Stationary Air Monitoring Data Fact Sheet
A benzene study paid for by Flint Hills Resources (Koch Refinery) and conducted by former TCEQ employee Laurie Haws has been the subject of some local meetings.
Using data from stationary monitors at fixed locations and comparing that to TCEQ health effects screening levels (ESLs), Haws concludes that local benzene measurements are below those that would be associated with health effects in people.
Study is fundamentally flawedAt the core of this study is data from stationary monitors; data from stationary monitors is not capable of reflecting what actual people are being exposed to. Monitoring is based on averaging which brings the numbers down – in essence, a numbers game. In addition, Dr. Neil Carman, Clean Air Director, Lone Star Chapter of the Sierra Club states, “Majority of air toxics monitors (including those tested for benzene) sample on average at dramatically lower flow rates and lower volumes compared to the breathing flow rates and respiratory volumes of human beings. A typical child is highly active and rapidly developing and so it has 2-3X the breath rate of an average adult.”
Furthermore, under oath, TCEQ employees have admitted to the limitations of monitoring data and have stated, under oath, that at times they experienced adverse heath effects from emissions along refinery row that monitoring data did not detect:
“Where – most often, when adverse health effects are reported by monitoring staff, we can’t verify it based on the measured concentration and the textbook knowledge on those chemicals. So, we know that there’s something in there causing health effects, but we can’t measure it sometimes.” – Vincent Leopold TCEQ toxicologist (USA vs CITGO pre-sentencing hearing (4/28/08)
“…the way I look at it is, the monitoring reports provide two kinds of information. One is the measured concentrations and the other is the reports by our staff. I mean, I guess if you want to look at it, I mean the human being is a monitor of sorts, perhaps a more perfect one than the scientific instrument…..There’s – lots of uncertainties. I don’t know what any one person was exposed to or for how long based on the monitoring data.” Vincent Leopold TCEQ toxicologist (USA vs CITGO pre-sentencing hearing, 4/28/08).
Tim Doty, of TCEQ Mobile Monitoring crew told a federal judge (5/1/08) that he and his crew often experience health effects while monitoring along Corpus Christi’s Refinery Row that include “burning nose, cough, irritated throat, nausea, burning eyes, everything along those lines.” Doty went on to testify that, “…there were times, frankly, that I feared for the safety of my crew.”
“The levels of chemicals in the samples taken at any fixed monitor would likely not represent the highest concentrations of chemicals in the air to which residents would be exposed because of the averaging that occurs from the fixed air monitoring stations, depending on the nature of the emissions released and the wind speed and direction.”

USA Today Report “Toxic Air and America’s Schools” (December 2008)
A Corpus Christi Caller-Times article (Refinery refutes benzene worries, 3/8/09) included a quote from Haws with respect to the USA Today report stating, “I think what they did, it was just information out of context.”
But apparently the new US EPA Administrator under President Obama, Lisa Jackson, disagrees.
In response to the USA Today articles, Jackson pledged at her confirmation hearing to act on the data within 30 days of her confirmation.
An E&E Article (3/2/09) states: “U.S. EPA today announced new testing of air pollution near schools, marking the first time the agency will take a systematic approach to identifying facilities with potentially dangerous air quality.”
"Questions have been raised about air quality around some U.S. schools, and those questions merit investigation," Jackson said in a statement. "EPA will work quickly to make assessments and take swift action where necessary."
Bottom-line:Monitors do not get sick when the pollution is real bad!
Monitors do not complain when the air is so bad humans find it hard to breathe.
Monitors do not metabolize benzene into its more toxic compound that produces cancer and leukemia.
The only safe level of exposure to a known human carcinogen like benzene is ZERO.
