The tank and all lines, including the vent, suction, return and remote fill ports, must be emptied of fuel oil.
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.
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.
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.
