I don't know what the NEC says, but I use to do pumps for irrigation systems with
a guy who knew the stuff inside out. And there is a way to set up a ground, locally.
And what I mean by locally, is that yes you may need 3 rods, and it depends on your
soil type, and drainage, moisture. So please be sure you are applying the correct
method for your soil.... And I think it may be smart to at least measure the potential
difference between your new ground, and the established electrical ground used for
your electric supply.... It may be smart to connect them together.... But be aware
that lightning strike protection may require running the ground wire from your bench
to the ground rod with larger wire, and at a distance, and specific route to the rod(s).
