Subject:Clarification on Ft Worth evaporation station-no scrubbers needed 

OK who can help and "reply all" to the others so that you do not duplicate efforts? First one to respond 

gets kudo's !!!! Air tests needs on the Arc Park/Brentwood compressor evaporation station for produced 

water.

Stick that canister right there too!

THANKS

Subject: Clarification on Ft Worth evaporation station-no scrubbers needed

Mr Harris of Intevras was able to clarify that the air stripper/scrubbers he described to me in the Evras 

evaporators are available when needed like in California, but that they are not needed and are not being 

used here at the Ft Worth Chesapeake Brentwood/arc park site because of the low hydrocarbons 

associated with the Barnett Shale. Also the air is not blended (as I reported earlier in this email string) 

unless it comes from the scrubber.

He also mentioned that unconventional shale gas has less VOC concentrations than the standard oil and 

gas reservoirs and that the Barnett is not heavy in metals.

He said that 50-60 ppm is what the Barnett Shale VOC has been although he's seen an average of 30 

ppm and also he sees areas that have little to no hydrocarbons in the produced water.

He said that radon is not a problem here compared to the North East areas of the Marcellus. Mr Harris 

didn't elaborate if there was any detriment to the air in incinerating arsenic, the conversation was 

limited to that arsenic occurs naturally.
In California, they did air testing on his units (with scrubbers) and found no problems when comparing 

baseline air tests to the incineration of hydrocarbons when that (scrubbed) air was run to the engines 

which was used as fuel for the engine as it is burned off.

We should get TCEQ to measure the air coming from the EVRAS engines before and during the air flow 

to be combusted.

I am still unclear if the flowback water that contains fracturing fluids go to the EVRAS incinerator, so an 

air test when evaporating flowback water is also in order.

If our air tests prove no detriment to our air, surely this system is to be promoted as a best available 

technology to take the truck fracing traffic off our highways and get us into Clean Air federal compliance.

I copied Mr Harris so that if he needs to further clarify, he can "reply all" and add comments.

Thanks for your attention to this matter.
