Narrative:

Flight was diverted back to departure airport because of maintenance issue. Aircraft already had bleed 2 deferred; and departing climbing through FL220 approximately. 'Bleed 1 fail' caution message appeared and the plane started depressurizing. We immediately asked center for a descent; and I took over the radios and controls; while the other pilot referenced the quick reference handbook procedures for the 'bleed 1 fail' message. ATC was only able to descend us initially to 15;000 ft because of terrain in the area; but gave us a heading and was able to descend us lower eventually. The message was cleared using the procedure in the quick reference handbook; but we decided it was better to return to ZZZ and have maintenance look at it rather than fly over the mountain with a chance of the same thing happening. After pulling in to the gate; I wrote up the aircraft. The maintenance controller and the mechanic troubleshot the aircraft and signed off on the write-up and we were ok to continue. Before departing; I personally spoke with the maintenance controller and he said if the same thing happened again I was to continue to destination; if we were able to clear the message per quick reference handbook procedures. So; once again we departed and climbing through FL220; approximately again; we had a 'bleed 1 fail' caution message appear I took over the radios and control and asked for a descent; and the other pilot performed quick reference handbook procedures and the message cleared. As instructed by maintenance control; we continued to destination. Before departing the second time; I discussed with maintenance control the issue from bleed 2 deferral; where the same sequence of events seemed to have happened and eventually led to the deferral. I was not given any guidance other than they could not find anything wrong with bleed 1 now. This would not have been concerning if we were not departing over the rockies where we have to deal with terrain; but we followed maintenance control and quick reference handbook procedures where it states continue with normal operations.

Title: An ERJ-170 with the number two bleed deferred took off from a mountainous airport and received a 'Bleed 1 Fail' alert. The flight returned for maintenance and was told if the fault cleared after the next takeoff to continue with both bleeds inoperative.
