We have a 2-family, 2-meter, 2-panel service.

The utility requires two ground rods with a #4 ground that loops through the ground rods out and back to the service disc. My question is would it be code compliant to bug on a #4 to each side of loop and go to the the second panel?
 
It doesn't matter what is compliant. The utility makes the call and generally that will not make consessions.

Code only requires a #6 and we could run a #6 from each panel to a different rod and then put a bonding jumper between the rods. But that is not what the power company wants and they can be difficult

Its been a while since I have looked at their spec book, but I think that gec loop back isn't actually a NYSEG requirement. Iirc, they show it in one of their installation diagrams and say something like "typical" or " recommended". I haven't done it that way in years and have never had anything said about it. The loop back is a very common instalation in central NY area, even in national grid territory

There spec does not have a multi-meter installation. What have you done for a 2-panel 2-meter installation?

I understand. But would the way I propose be a code compliant installation?

That would be NEC compliant. That would essentially be the "grounding electrode conductor taps" method. I find it easier to use the "common location" provision and hit the meter socket. Often on a two family, I am using 230.40 exception 1 so the panels are not close together which makes it a pain the hit the panels.
