Underground oil tanks were once a popular solution for home heating—especially in older homes across the Northeast and Mid-Atlantic regions. But as technology has evolved and environmental awareness has grown, these buried tanks have become more of a liability than an asset. Leaks, corrosion, and contamination are serious concerns, making underground oil tank removal an essential task for many property owners.
If you’ve discovered or suspect an oil tank buried beneath your property, don’t panic—but don’t ignore it either. In this blog, we’ll walk you through how professionals handle the process from detection to safe disposal, and why hiring experts is crucial for your safety and peace of mind.
Step 1: Detection – Finding the Hidden Tank
Many homeowners don’t even realize there’s an oil tank on their property until they spot signs such as a capped pipe in the yard, uneven landscaping, or documentation from previous owners. If you suspect a buried tank, the first step is confirmation.
Professionals may use:
Ground-penetrating radar (GPR)
Magnetometers to detect metal underground
Soil sampling for oil residue
Historic property records and permits
This step is vital to ensure no accidental damage or contamination occurs during future excavation.
Step 2: Permits and Planning
Once a tank is confirmed, professionals begin planning the removal. In most areas, including states like New Jersey, Maryland, and Pennsylvania, permits are required before digging can begin. Tank removal companies handle:
Filing for local or state permits
Notifying environmental agencies if needed
Scheduling inspections
Coordinating with utility companies for safe excavation
This paperwork is critical to ensure the process complies with local and environmental laws—and protects you from legal liability.
Step 3: Safe Excavation
Once all approvals are in place, the removal crew begins excavating the tank. Using excavators or backhoes, they carefully dig around the tank to avoid punctures or spillage.
The tank is uncovered and cleaned of residual oil.
Any leftover fuel or sludge is pumped out into approved containers.
Hazardous materials are properly disposed of according to environmental standards.
This is not a DIY job—improper handling can result in soil and groundwater contamination, which is both costly and harmful.
Step 4: Tank Removal and Inspection
Once emptied and cleaned, the tank is lifted out of the ground using specialized equipment. After removal, a thorough inspection follows:
The tank is checked for leaks, corrosion, and damage.
If leaks are discovered, soil sampling and contamination testing are required.
Contaminated soil may need to be excavated and replaced.
This inspection is usually documented and reported to local authorities to close the permit and ensure environmental compliance.
Step 5: Disposal and Site Restoration
After inspection, the tank and all associated materials are transported to licensed recycling or disposal facilities. If any contaminated soil was removed, clean fill dirt is brought in to restore the excavation site.
The removal company will:
Fill and level the ground
Seed or sod the area if requested
Provide documentation proving the tank was removed and disposed of correctly
This is especially important if you plan to sell your home, as most buyers and real estate agents require proof of safe tank removal.
Why Hiring Experts Matters
Underground oil tank removal isn’t just about digging and hauling—it’s a complex process involving environmental risks, legal compliance, and safety concerns. Professionals bring:
Experience with local codes and environmental regulations
Proper tools and equipment for detection and excavation
Certified waste disposal methods
Insurance coverage for any unforeseen complications
Attempting this process on your own or hiring an unlicensed contractor can result in fines, failed inspections, or even long-term property damage.
