Abandonment of Underground Oil Tanks
A2Z will obtain the required permits for the customer and arrange for inspection by the DEC along with a utilities mark out.
First, we excavate the ground to the top of the tank, then the tank is cut open and all fluids/sludge is removed and disposed with a vacuum truck from the exposed tank. We squeegee clean and rag wipe the interior surface of the tank and remove the cap, fill, vent, supply and return lines. If the customer wishes A2Z will obtain soil samples through the tank bottom for testing as proof no discharge has occurred.
The tank will be filled with certified clean sand or gravel and the ground surface restored with on-site clean soil and new topsoil/seed. All necessary information is provided to the city to insure a Certificate of Approval (CA) is issued for the property.
