Gas release at Matlock and Debbie Lane two schools locked down

Here are excepts from the original news report….(MY COMMENTS INTERJECTED WITH PARENTHESIS)
Release at Mansfield natural gas drilling site investigated
(by Rusty Ward = fail)

MANSFIELD — The unexpected venting of natural gas at a Carrizo Oil & Gas well site Friday morning, which briefly put two schools on alert, shows the need for gas inspection and training programs, Arlington Fire Chief Don Crowson said.

…Arlington and Mansfield firefighters were called to the site, 1751 E. Debbie Lane, near Matlock Road just before 8 a.m. after residents called 911 to report “smoggy mist” and noise. Students were kept indoors at James Coble Middle School and Brockett Elementary for about 45 minutes during the release, which created a loud hissing and sent a white vapor cloud through surrounding neighborhoods.

No (latent) injuries were reported, and firefighters did not detect natural gas in neighborhoods or near the schools downwind.

Carrizo and fire officials say they believe corrosive sand in the pipeline of a newly producing well caused a small rupture in a valve and allowed water and natural gas to vent at high pressure for about 20 minutes (30 min spewing per TCEQ report #166368) before the system automatically shut down.

Crowson said that the primary and secondary automatic safety valves failed after the rupture but that a third valve eventually shut off the gas flow.

…..’Choke valves … fail’ (Dan Petri of Carrizo emailed TCEQ to report that the sand blowout created a 1/2 inch hole in the wellhead)

The first firefighters arrived about six minutes after the first 911 call, Crowson said. It took about 30 minutes for a Carrizo representative to arrive after being contacted by firefighters, officials said.

By then, the automated shutoff system had kicked in and “there was no imminent danger,” according to a Carrizo report.

“This kind of stuff happens. You will have choke valves that will fail,” said Rusty Ward, Carrizo’s vice president of regulatory affairs (and former UTA VP of finance who was instrumental in the 22 oncampus gaswells). “There are so many redundant safety devices on these well sites. If one thing doesn’t shut it down, something else will.”

School officials kept children indoors for about 45 minutes and turned off air intake vents at Coble and Brockett as a precaution, officials said.

“At Brockett there was some odor in the air, (TCEQ reported no odor when they arrived 3 hours later) but our students were not in any danger,” Principal Chuck Roe said in an e-mail to parents.

……’Never any danger’

By Friday afternoon, the damaged section of pipe had been repaired and the well was returned to production, according to a Carrizo report. An estimated 3,400 cubic feet (70,000 cubic feet on final report) of natural gas and about two barrels (2.7 barrels on final report) of water (toxic, produced water) were vented. The well produces about 6 million cubic feet of natural gas a day, Ward said. (Third party consultant on final report calculated only 4.4 pounds of VOC’s in total were released which is under the “reportable quantity” of 5,000 pounds in 24 hours so this was a non-reportable emissions event.)

The steam (aerosol, toxic brine) reaching the residential contained no natural gas, and any odor reported could have been sulfur (H2S?) that is added to natural gas so it can be detected, Ward said. (Mercaptans are not usually added until a utility processes the gas for shipping to the ultimate customer, via pipeline.)

“That small amount of gas was completely on top of the atmosphere by the time you got to the wall of the drill site. There was never any danger to a kid or residents,” Ward said.

Wow! I woke up to the noise of what I thought was a plane crash and what sounded like a jet engine with fumes in my neighborhood. I walked to Mansfield Webb and Debbie lane and saw plumes of smoke yet no one madeANY announcements about this.

Subject: just rec’d Debbie Lane emission event report

On page 5 of 6 of incident complaint# 166368 & 166436 on 3/23/12… why do you only quote your regional records to show that Carrizo has no previous complaints for odor during the past five years? The UTA Carrizo site (although is state regulated) has numerous odor complaints.  I myself have filed other (non-state)Carrizo sites- a good example is…. Incident report 151697 had a TVA VOC reading of 1,140,000 ppb by my son’s school on March 4, 2011.
I also question what follow up/methodology TCEQ does to ensure the accuracy of the third party consultants that came up with the math that arrived at only 4.4lbs of VOC’s released in a 30 min time frame which resulted in a (Carrizo) self reported, toxic, brine loss of 2.7 barrels and 70,000 cubic feet of emissions released.
I also question the waste of taxpayer money to deploy a suma(whose lab results took 4 months)canister air test 3 hours AFTER the emission event had dissipated? I have asked our firechief to keep suma canisters with them on their firetrucks and have been refused.
My last question is why the incident report did not include the emissions canculations and gas analysis for the sand blowout that Mr Petri emailed Mr Yerkes?  Can you please send that to me?

Subject: About yesterday’s gas well release at Matlock and Debbie Lane….
Assistant Fire Chief Self, I have asked Mr. Marshall of the Railroad Commission 903 984-3026 to have Carrizo do a soil test using an independent agency. They need to test the soil on site and in the fallout residential zones immediately! If our dry gas contains less than one half of a percent of benzene, then lets prove that!  Unfortunately “any” amount of benzene is not safe, especially if ingested or if it enters the storm water system. OMG I can see it now…..a dead zone of grass where the brine, heavy metals, hydrocarbons, NORM, and residual fracking chemicals mist landed. What if that toxic fluid spray mist landed in people’s lungs?
I am grateful that a photo was taken so the public can see what a “release” emission event looks like.  If this would have happened past the separator and the fluids were not involved, I imagine that it would have looked like the emission event at Sublett and 360 last April?
I guess if folks wanted to see different samples of complete blow out events to feel better about this “release” in Mansfield, then a good (but very unsettling) video to watch is

About Kim Triolo Feil

Since TX Statute 253.005 forbids drilling in heavily settled municipalities, I unsuccessfully ran for City Council Seat to try to enforce this. Since Urban Drilling, our drinking water has almost tripled for TTHM's. Before moving to Arlington in 1990, I lived in Norco’s “cancer alley”, a refinery town. It was only after Urban Drilling in Arlington did I start having health effects. After our drill site was established closest to my home, the chronic nosebleeds started. I know there are more canaries here in Arlington having reactions to our industrialized airshed (we have 55-60 padsites of gas wells). Come forward and report to me those having health issues especially if you live to the north/northwest of a drill site so I can map your health effects on this blog.

  1. Good to know that the principal is an environmental expert and that the kids weren’t in any danger! What an idiot! “yea….we smelled something, but it’s all good….recess everyone!”
