In-Ground Tanks

When you discontinue use of an underground oil storage tank (UST) or when the in-ground tank is found to be compromised, the tank should either removed or secured (technically called “tank abandonment”).

In-ground oil tank removal is much, much more than just digging a hole…

    1. Establish the precise location of the existing underground oil tank (UST)
    2. Establish location of potential nearby underground structures and utilities (leach field, sanitary sewer, storm drains, utilities, etc.) — We call BEFORE we dig!
    3. Obtain applicable town and state permits
    4. Install replacement oil tank (selected from among 23 alternative types and sizes offered by MTR) to ensure continuous burner service during the oil tank removal process.
    5. Remove any liquids and oily sludge remaining in the tank and recycle in accordance with EPA regulation
    6. Excavate the pit in which the oil tank resides, plug and seal oil lines and remove breather tube(s)
    7. For TANK REMOVAL the oil tank is hoisted to the surface and hauled from the work site for recycling in accordance with municipal, state and federal regulation.
      • MTR will provide the homeowner with a Certificate of Disposal and soil analysis necessary for property sale or transfer.
      • Take soil samples from the pit created by removal of the in-ground oil tank and send to certified laboratory to determine degree of soil contamination, if and
    8. When TANK ABANDONMENT is deemed appropriate, we follow the NFPA (National Fire Prevention Act) 30 Guideline as follows:
      • A hole is cut in the tank and a member of the team enters the tank and scrubs thoroughly to remove any residual oil.
      • Soil samples are acquired through holes, drilled from the inside, at each end of the base of the tank.
      • These samples are analyzed by a certified laboratory, results of which may be used for closings or insurance purposes.
      • The tank is then filled with slurry (pour-able fill)
