Ah, yes, there was a ruckus out here, early on. Maybe it was in the fallout of that suit that the refiners posed the option to the gov't over which oxygentate to use.
Aw, heck. My wife could lay it out point-by-point; she was a QA Lab Chemist with one of the biggies for years and saw it all go down from the inside; first the gov't pushing one way, then the other. Always an opponent of big gov't, she never got so chummy with her employer as to indulge any bias that direction, either, though. She's as stright-up and no-nonsense as they come and has one of the most sensetive "BS Meters" Ive ever encountered.
Everyone should have wives that are omnipotant BS dectors!!! Mine is like that too!!! But she's not a chemist outside the kitchen!!! (grin)
