General Motors is also drilling on site of their plant.

..... Dr Sterling, I am writing to you because Dr. Ramone Alvarez from the Environmental Defense Fund recommended I contact you. I was also wanting to also thank you for your work with Dr Sattler on the Ft Worth League of Neighborhoo ds.

Yesterday I attended the NCTCOG meeting where Dr David Allen of Univ of Tx, Austin gave a presentation of the influence of gas shale emissions on ozone levels http://www.nctcog.org/trans/committees/ntcasc/OGTF/052511/Items2and3.pdf which pretty much started out by saying that it is xylene and ethylene that are the ozone culprits being the HRVOC and not

methane.

The presentation showed that the Maximum Increment al Reactivity for ozone was meta xylene at 9.75, ethylene 9, in comparison to propane at .49, ethane .28, benzene .101, and methane .014 which takes the focus off of drilling effluents (while recognizing that benzene is a public health issue).

When learni ng about xylene, I am reminded by Councilman Mel LeBlanc's statement about how the General Motors plant here in Arlington TX emits an astounding amount of VOC's. I also remember that a resident living within 600 feet of the gas wells at UTArlington tested positive for m,p

- Xylene. FYI I live within a mile directly north of the UTArlington gas production plant.

I also live within a mile down wind (to the west & north) of GM. This information is troubling especially today as GM will announce their expansion plans in Arlington. Toxic risk.com showed the GM facility in 2007 having 190 tons of which the bulk of that is 85 tons (45%) per year of xylene,

44 tons of n

- butanol, and 40 tons of trimethylbenzene

I recall reading that roadside vehicle emissions need d ispersion setback of at least 33 feet from humans (which is why I don't support bike lanes in traffic). My question is what is the setback needed if living near an automotive plant? I was wondering "where" the HRVOC/ozone production from GM's massive xyl ene emissions was occurring? Is it occurring directly overhead the GM plant/moving plumes in our air shed? Would those most closest to GM be most effected/exposed to this ozone hot spot? Where is the highest concentrations of xylene/ozone fallout occurring ? Would those people at Six Flags and the Cowboy Stadium and city workers and those in a one mile radius be most effected?Then my next question is about the Jacobson Effect where I understand that an already highly polluted

area under the right conditions experience an exponential ozone effect. Urban dwellers then are in double jeopardy in co

- existing in our man made, ground level SMOG (dome like) encasement of pollution. How much worse then for those near GM?

I tried my best to defeat Chesapeake from ha ving a drill site in the downtown/Entertainment Disctrict and I sited GM as already too taxing in my airshed. I have seen firsthand birth defects and asthmatic citizens and those with cancers when taking a 500 petition street venture.

None of the information I am learning makes the area near UTArlington and the Entertainment District a livable or visitable area. How dead on is my fears?

Sincerely,

Kim Feil
