The Staten Island Time Bomb: "Abandoned" Buried Oil Tanks

If you are buying or selling an older home on Staten Island, there is a massive, invisible financial risk potentially lurking in the backyard: an underground storage tank (UST) for heating oil.

Decades ago, when many Staten Island homeowners converted their heating systems from oil to natural gas, they faced a choice with their old buried tank. The expensive option was to dig it up and remove it. The cheaper, faster option was to "abandon" it in place—usually by pumping out remaining oil and filling the tank with sand or foam.

For years, "out of sight, out of mind" was the operating principle.

Today, that buried tank is a major liability that kills real estate deals, scares off lenders, and complicates insurance. If you are involved in a transaction for an older home, you cannot afford to ignore it.

The Myth of "Properly Abandoned"

A seller might present a piece of paper from 1995 stating that a tank was "properly abandoned in place." They might genuinely believe this resolves all issues.

It does not.

Paperwork from twenty years ago proves only that someone paid to fill a tank with sand. It does not prove that the tank didn't leak oil into the surrounding soil *before* it was filled. It also doesn't account for the fact that metal tanks continue to rust and corrode underground, potentially releasing any residual sludge years later.

The problem isn't the tank itself; it's the soil around it. If that soil is contaminated, the NYS Department of Environmental Conservation (DEC) can designate the property as a spill site. The cleanup costs for contaminated soil can easily run into the tens of thousands of dollars—sometimes much more if the contamination has migrated to neighboring properties or groundwater.

How It Could Kill Your Deal

Even if you are willing to take the risk, the other parties necessary for your closing may not be.

1. Lenders May Get Nervous: Mortgage lenders are acutely aware of environmental liability. A buried tank represents a potential catastrophic loss in the value of their collateral. Many lenders will hesitate or outright refuse to issue a mortgage on a property with an existing UST, even an abandoned one, until environmental soundness can be proven.
2. Insurance Could Become a Roadblock: Homeowners' insurance policies increasingly include exclusions for pollution or pre-existing contamination. A buyer may find it difficult or prohibitively expensive to secure proper coverage for a home with a buried tank.
3. The Last-Minute Panic: Often, the existence of a tank isn't disclosed until late in the process—sometimes in the Property Condition Disclosure Statement (PCDS) delivered just before signing, or discovered during a home inspection. This can lead to delayed closings, frantic renegotiations, or deals falling apart completely at the eleventh hour.

The Solution: Testing and Contract Protection

So, how do you handle this common Staten Island reality?

The Gold Standard is Removal. The only way to be 100% certain a tank is not a current or future liability is to have it excavated and removed by a licensed environmental contractor, who then tests the soil from the tank grave to confirm it is clean. Sellers who do this *before* listing their home remove a major obstacle to sale.

The Compromise is Soil Testing. If removal is not happening, a buyer should never rely on a simple metal detector sweep to "find" a tank. You must demand soil borings taken from around the tank to test for contamination *before* you are locked into a contract.

Contractual Protection is Vital.

• For Buyers: Your contract needs specific contingencies that allow you to conduct environmental testing and to walk away or force the seller to pay for cleanup if contamination is found.
• For Sellers: If you genuinely don't know the history of a buried tank, you need contract language that clarifies you are making no representations about the environmental condition of the property.

Conclusion

A buried oil tank is not a minor cosmetic defect like chipped paint. It is a major environmental and financial risk factor that can survive for decades.

This is exactly why you need an attorney involved *before* you sign a contract—someone who knows the specific physical risks of Staten Island housing stock and knows what questions to ask.
