Situation: Existing single family residence with 100 amp service with the grounds and neutrals connected to the same busbar. Building a new attached garage and installing a new 200 amp panel and moving the service drop to that panel and feeding the original 100 amp panel out of the new panel. 250.32(B)(2) seems to be saying that if I do not run an EGC then the grounded conductor can be bonded to the grounding electrode conductor at the second building as well as at the service, is that the case or am I missing something?
