I have a situation that involves a remote vent for an underground gasoline storage tank.
NFPA 30 requires this vent to be at least 12' tall, and section 4.5.3.4 requires it to be grounded or bonded.
I pull a conduit from my site monitoring equipment out to this remote vent to monitor it.
The conduit will have a communication cable for a sensor, but not ground wire. I feel that if I drive a ground rod at the vent then I cause a difference in potential that could cause problems.
Do I just pull a ground wire in the conduit with the cable and bond it to the metal vent piping?
By the way, I forgot to mention the underground piping to the vent stack is non metallic.
