http://www.tceq.state.tx.us/assets/public/comm_exec/pubs/rg/rg360/rg36010/appendix_a.pdf the bottom of page A-24 states “Note that the information from devices such as lower explosive limit (LEL) detectors, chlorine residual measurements, and total organic carbon measurements do not qualify as adequate monitoring or control technology;….”
I have contacted Industrial Safety Supply Corporation to see what equipment we should be spending money on in knowing what BTEX and other gas drilling effluents are present when our police and firemen go to these drill sites. I told them they use the QRAE device and per Mr. Michael de Diego, of Industrial Safety Supply Corporation, and I quote him from an email…“The only way to do this correctly is with a PID unit.” So last night I spoke at our Arlington City council meeting and said …….
“In today’s early session agenda items, Neighborhood Improvements Using PIDs does not mean detecting hazardous toxins in neighborhood’s using a Photo Ionization Detector, but rather the acronym PID stands for Public Improvement District, and today’s discussion related to the assistance in replacing a falling masonry wall. Clap, clap, clap…bravo….you can “see” that the wall needs help, but you cannot see or fix BTEX or other “nonexplosive” conditions at these drill sites that “do” pose a threat to the public. Toxic air pollution at drill sites can fall into three categories …
1)Pre-production high doses, (that Arlington gas well inspectors do not visit during these active site times because of safety protocols)
2)Post-production, chronic low doses that per the TCEQ Inventory, I figure averages about 2 tons per year per site not including compressor stations and “if” properly functioning.
3)Ill maintained or malfunctioned equipment or infrastructure.
If any of these sources are “not” registering on the QRAE machines that our firemen use, then per one QRAE distributor, Mr. Michael de Diego, of Industrial Safety Supply Corporation,
and I quote from an email “The only way to do this correctly is with a PID unit.”
