2020 NEC 250.32. Only the CEE grounding electrode is needed to satisfy the code?

[Jamesco]

Main structure. POCO pole with meter and main service equipment mounted on pole.

Separate residential dwelling structure.
Feeder from main structure to structure 1 phase 3 wire 240/120V 200A +EGC.
Plastic domestic potable water line serving structure.

Using 250.50 and 250.52 (A) (3)

All requirements for the CEE are meant. I see no requirement for a supplemental grounding electrode. Am I wrong?

 

[Joe.B]

Yes, that is my understanding. No supplemental grounding electrode required.

 

[augie47]

If that's the only electrode available, that's all you need.

The change for only requiring a CEE was made several code cycles back.
But the CEE has to qualify and likely the AHJ wants to see the connection. A vapor barrier at the bottom of the footer will disqualify the CEE
