Unless you have one of the National gas companies, i.e. Chevron, Shell , Exxon, etc. on the hook for any long term remediation, I would not touch it. I had a situation that proved to be a mess with concrete filled tanks that came up clean on a Phase 1 only to discover that there was contamination below. It cost $250K+ to clean up (and I have seen them cost well over $1mil. Thankfully for us, it was Chevron's expense. Be very carefull. I would walk away. Too much else available.
