After aborting one approach and holding for several minutes, the flight was cleared for the ILS approach runway 32 at 0947 EST. While the flight was holding, the crew had several conversations with approach control and the company representative regarding runway conditions and braking action. On 2 occasions, the United crew requested, through the tower, that airport personnel inspect the runway. The tower was unable to contact anyone and stated that the last field condition report was taken at 0815 EST. The crew was also informed that the field was completely whited out and there had been no plowing since the snow started. The approach and touchdown were normal with the left main gear touching down about 20 ft inside the left edge of the runway about 1200 ft from the threshold. The left main gear left the runway approximately 400 ft later and traveled an additional 750 ft before the right gear ran off the runway. Prior to stopping, the crew was able to get the right main and nose gear back on the runway.
