I have a fight with a chief electrican of a facility, and maybe also with the AHJ. This facility has installed a separate ground rod at every 480 208 volt transformer in a large facility (250,000 square feet). We inspected all the transformers, and most of them have a ground rod, no bond from the ground bus of the transformer.
