Inspector Disapproved Copper Rod with Ufer and Instead Used a #4 Rebar

It looks similar to this type of footing used with monolithic slabs:

Yes, he connected the rebar in the ground with another rebar to the footing rebars.
The rebar from the footing is your Grounding Electrode. The tied on upright rebar is not per code, but neither is your copper rod. One single rebar in the footing and turned up or a piece of conductor are the proper choices,

Similar but not 1', has the barrier, not on undisturbed soil or even compacted by the looks of it. PP quality, let alone a grounding electrode.
So even without the barrier you're saying the slab in the OP does not have a footing?
 
Grounding electrodes are a waste of time generally but if that does not meet the requirements of a footing, how can it be considered for use as an encased electrode?
Ignoring the vapor barrier, if it were designed and installed correctly this could meet the definition of a monolithic footing as per post #24. The NEC does not define a footing so it is acceptable to use other resources for the definition. If the design used in the OP were considered a monolithic footing by local officials then it would need to be used as the CEE.
 
Not only does the NEC not define a footing, does not strictly require the CEE to be in a footing. It says 'foundation or footing'.

The method of bringing a piece of rebar out of the foundation to the GEC connection is permitted, but not required. Connecting the GEC directly to the rebar before pouring is explicitly permitted. (See 250.68(A) exception 1). Moreover the method of bringing the rebar out of the foundation through the dirt without protection (as seen at arrow 2 in the OP pic) is explicitly *prohibited*. (250.68(C)(3)(b)

All that said, the vapor barrier makes the CEE at least borderline for me, too, anyway. I'd say drive another rod and forget about it.
 
As has been discussed, with a vapor barrier there's no CEE, so something else would be required. Why not two rods though.
I understand that, but from reading the OP, it doesn't sound like that was his intention by installing the rod. He never mentioned the vapor barrier, that was brought up by another poster.
 
Hopefully the original poster will return with some further details. From what's shown in the OP the CEE isn't going to work so just install two ground rods.
 
Appears the ground clamp he used is the type normally only used on copper tubing. The much heavier acorn ground rod fitting with a hex headed bolt is the only one we used on ground rods.

We would typically see those on water pipes but some of that style are also listed for rods.
