Keep in mind that 10.6.8.1 states, "The requirement of 10.6.8 (prohibition against using UG piping as a ground) shall not preclude the bonding of the underground piping to the lightning protection grounding system as required by NFPA 780 in those cases where lightning protection is provided for the structure."
