**THE FOLLOWING INFORMATION IS FOR HEATING OIL TANKS LESS THAT 1,100 GALLONS**
When should I consider replacing my old underground tank?
If your tank is 25 years or older, you should consider replacement. Do not wait for your tank to fail before you take action. This could be very costly!
How do I take my old tank out of service legally?
Obtain the services of a contractor to abandon the old tank in place. Very often your oil company will do this work or recommend a contractor. You may do this work yourself if you conform to the requirements described below. Using the appropriate forms, notify the Health Department seven days in advance of the abandonment. If the tank is not leaking,
Forms for this purpose may be obtained by downloading them from the Underground Tank Notification Forms page, by calling the Department at (516) 227-9691, or from your contractor or oil supplier. Along with the paperwork, submit a check payable to the Nassau County Department of Health for $55.00 for each tank abandoned in place.
Tanks may also be removed in their entirety after proper notification to the Department. Please contact the Department at (516) 227-9691 for the form used for this purpose.
What does a proper tank abandonment involve?
The tank must be completely emptied of oil including any remaining residue/water. A hole is cut in the tank and sand, concrete slurry, or an approved foam product is used to fill the tank. All lines to the tank are cut below grade and plugged. If you continue to heat with oil, install a new fiberglass underground tank or a steel aboveground tank. The new tank is then connected to your heating system using all new materials.
Will my tank closure be on public record?
All tank removals and abandonments are recorded on a county database and a record can be obtained through this Department by calling (516) 227-9691.
