ECN Forum Forums Code Related Discussion NEC & other Code issues Re-Bar as part of the Grounding Electrode System

You are more or less correct, Jim. You certainly do not need a ground rod, plate, etc.

You still need to bond the plumbing, though. The NEC, notorious for poor grammar, continues to refer to the water bond as a grounding electrode. It's pure semantics .... with a Ufer we're not relying on the plumbing as a GEC, but are instead concerned with clearing a fault to the plumbing.
