Yes, it is my understanding that the introduction letter explaining the TAZ update process and soliciting some info, like agency contact went out in the beginning of October to all the usdot divisional offices. They were instructed to pass it to their state which inturn was to pass it to the MPOs. Right now all i can say is don't worry, you are not alone, and the originators of the letter are on this list serve. I don't want to make any recommendation like call Tom Mank of FHWA since I do not (as yet) know what plan B is. I can tell you that the MPO in northeastern Illinois has not seen it yet either. I just asked around the agency today and no one has seen it. ed christopher director or information services chicago area transportation study
