Small Facility/Homeowner  Oil Tanks

Small Facility/Homeowner Oil Tanks (Heating Oil Tanks less than 1,100 gal.)

REPLACE YOUR OIL TANK BEFORE IT LEAKS!

A TANK THAT HAS LEAKED CAN BE VERY COSTLY!!

HOW TO REPLACE YOUR TANKS LEGALLY

If you store 1100 gallons or less of heating oil in an underground tank, you should consider replacing it with a new tank, especially if it 25 years old or older. Homeowners and other small facilities that wish to abandon their non-leaking tanks must take the following steps:

TANK ABANDONMENT

  1. 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.
  2. Submit the appropriate forms to notify the Health Department at least seven days in advance of the abandonment.  If the tank is not leaking, to the best of your knowledge, include with the notification a notarized statement attesting to that effect.  Additional forms for this purpose may be obtained on this website, from the Health Department by calling (516) 227-9691 or from your contractor or oil supplier.
  3. Along with the paperwork submit a check payable to the Nassau County Department of Health for $70.00 for each tank abandoned in place.
  4. 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.
  1. The tank must be completely emptied of oil including any remaining residue/water.  Any waste product removed must be disposed of in accordance with all local, state and federal regulations.

TANK REMOVAL

  1. Obtain the services of a contractor to remove the old tank.  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.
  2. Along with the paperwork submit a check payable to the Nassau County Department of Health for $90.00 for each tank removed.
  1. Submit the appropriate forms to notify the Health Department at least seven days in advance of the removal.  Written notification of a removal must be submitted to the Department of Health detailing the tank size, location, and date of removal at least seven days in advance of the removal. 
  1. All liquid and residue must be removed from the tank and connecting lines. Any waste product removed must be disposed of in accordance with all local, state and federal regulations.
  2. The direct fill, remote fill and vent lines must be cut or removed to a point below grade. The lines must be permanently capped or filled with an approved inert material to prevent any possibility of an accidental delivery after removal of the tank.
  3. After the tank is cleaned and rendered vapor free, holes must be punched in the tank to make it unfit for the future storage of liquids. The tank can then be disposed of as scrap.
