Narrative:

Bleed leak in-flight. Passing through FL300 with an assigned speed of .74 mach, we received a bleed leak indication on the EICAS. We initiated emergency procedures followed with the manual recommended procedure and then descended to FL240 hoping to continue to ord. When throttle was advanced, bleed leak indication came back on EICAS. We had already contacted air carrier and maintenance control and so called them again, telling them of the continuing problem, then advised them we would divert to grr. We used the checklist as a precaution, and with the flight attendant and passenger briefed, ATC notified of intentions, and emergency equipment standing by, made a normal landing. Passenger were taken off via jetbridge with no one injured. Supplemental information from acn 558187: captain contacted air carrier and maintenance control explained problem. Asked for suggestions. Meanwhile, we descended to FL240. After leveling, I advanced thrust levers and bleed leak reappeared. Captain contacted air carrier and maintenance control again. Discussed problem. Maintenance control supervisor came on line and suggested that this was not an emergency. Captain explained that it was an emergency, and that we were diverting to grr. As a precaution, #2 engine was left at idle and we used single engine procedures.
