The section Tom references is in regard to electrodes which may be used to ground services. I don't think this is what you are inquiring about.
Also, an underground tank is as grounded as it can possibly get, so "grounding" it electrically wouldn't make much sense.
This leaves us with the 'potential' need to bond the tank to the electrical system to create an effective fualt path, or to bond the tank for the purposes of creating an equipotential gradient. I don't believe either is necessary...

Is the tank cathodically protected?, if so I doubt the tank installer wants it bonded. It would void the warranty offered by the tank manufacturer
