Narrative:

On climb out from ord, we encountered in-flight icing conditions. A few moments later, we received a master warn flasher and bleed #1 overtemp EICAS message. We followed aom procedure and that extinguished the message. We informed ATC that we would need to stay FL250 and below per the checklist. We then consulted with maintenance controller and dispatch. Since there were no alternate airport destinations without icing conditions, we decided to return to ord. We felt ord would be safest, because we did not encounter much ice and we did not know how severe the icing at destination could potentially be. Flight continued to ord without further problems. Single bleed operation in icing worked great and we did not encounter any significant amount of ice during descent and approach.
