Benefits: Abandoning a tank in place is generally less expensive than having it removed from underground. Filling the tank will help prevent future collapse of the tank and any structure above the tank. Disadvantages: The top of the tank needs to be exposed which may impact the landscaping. If no soil test are taken, the question of soil contamination has not been addressed and could become an issue at any time in the future.

1. Obtain the necessary local permits. Contact the local fire, planning or building departments for information on local requirements.
2. Find out what product is in the tank (heating oil, kerosene, waste oil, water, etc.).
3. Drain and flush all piping into the tank, being very careful to avoid spilling.
4. Have the residual heating oil pumped from the tank. Remove any solids or sludge. Any material which cannot be recycled must be disposed of in accordance with applicable Federal and State regulations.
5. The top of the tank is uncovered and a large hole is cut into the top of the tank so there is an even distribution of sand is filled into the tank.
6. The vent and fill pipes are cut off below grade and plugged.
