Oil tank removal and oil tank abandonment might sound like the same thing, but in reality they are quite different. Oil tank abandonment is a process where the tank itself remains in the ground. The oil is removed from the tank, then the tank is filled with a type of gravel or foam, then it is closed. Oil tank removal is exactly what is sounds like. The tank is fully removed from the ground, the area is filled, and the tank is taken away and disposed of properly. In both cases, soil around the tank must be sampled to determine if a leak has occurred.

Which is preferable? Removal can be required due to leakage,and unless the tank lies partially under a structure, removal is almost always the better option. Abandoned tanks still run the risk of a leak, and a leaky tank will result in a much more expensive clean up. In addition, if a tank is removed entirely, the presence of the tank will not prevent further construction on the property. Under certain circumstances, property owners may be required to prove a tank properly abandoned, or additional testing may be required to ensure the tank is not leaking. If the tank is removed, this is not the case.

Up until quite recently, underground oil tanks were made of metal, and they last about 15 years before they are in danger of rusting and leaking. For this reason, sooner is better than later when it comes to removing an oil tank on your property. While it can be a daunting task, hiring a contractor that is certified and experienced in oil tank abandonment and removal is essential to give you the peace of mind that the work will be done safely and properly.
