Hi everyone, again. My last oil tank question for a while-I promise! If you were to abandon, would you use the sand, concrete or foam? Does anyone know of any advantages/disadvantages? I have learned more about buried oil tanks in the past couple of weeks than I ever wanted to know!

When we did our's a year ago we used foam. We talked it over with a couple of companies that did that sort of work and they all agreed that foam was a good choice and we'd only be wasting money to go with concrete. I don't remember sand being an option for us - just foam, concrete or removal.
Maybe use Pea gravel, it doesnt' compact over time, wont carry moisture like sand so wont rust out the tank. Probably cheaper too. If it was fuel oil odds are its intact anyway. Gasoline tanks fail at a much higher rate than heating oil tanks. If it was only a 300 gallon tank or so I would dig it up and odds are in your favor that it never leaked. Normally your problem would be from the fuel company over filling the tanks and spilling on the ground. We have lots of burried fuel tanks in alaska and have not the issues your talking about, then we are not over regulated yet.
Have the tank removed. Removing the residual oil from an underground tank ranges from difficult to impossible. I think it is a matter of paying a lot now or paying a whole lot more later.

Your isolation distance from an oil tank is 100 foot, to drill a water well. Here in Michigan it is 50 foot. That is a higher regulation. Pea gavel was not on the approved list. Read the links.
