I just finished my code update class today and gas pipes were ofcourse a topic.
According to Art. 250.104(b), as several of you have stated, the gas pipe is required to be bonded, however, the equipment grounding conductor can be used for this purpose.
According to my instructor,(a local AHJ), the gas pipe need not be bonded with any bonding jumpers since the E.G.C. is allowed to act as the bond itself.
According to him, the E.G.C. meets the requirements of the code and no further bond is needed.
