I believe I answered my own question; I looked in NFPA 30 and it sent me to NFPA 77. Section 8.5.2.2 answered my question. In a nut shell, it is saying that storage tanks for nonconductive liquids, including these tanks on supports, on grade level foundations are considered grounded regardless of the foundation (e.g. concrete, sand or asphalt) and that the addition of grounding rods and similar grounding systems will not reduce the hazard associated with static electric charges in the liquid.
