We usually don't answer home-owner questions, but...
250.104(B) Other Metal Piping. Where installed in or attached to a building or structure, metal piping system(s), including gas piping, that may become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or to the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122 using the rating of the circuit that may energize the piping system(s). The equipment grounding conductor for the circuit that may energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.
Could it become energized? If not, not required. Maybe? Either way that would be up to inspector to decide. If you want it bonded, thats another story... And yes, to the ufer with a split-bolt in an accessible location would be OK, from a clamp in an accessible location on the pipe. IMO If this is for say a home shop, or something, I would.... But have your electrician do it...
