The first chilly mornings of October usually send New Jersey homeowners down to the basement to check the furnace or boiler. If you’re buying an older home this fall, there’s another heating question worth asking, and the answer may be buried in the yard: is there an old heating oil tank on the property?
Plenty of older homes in northern and central New Jersey were heated with oil at some point, and when owners switched to gas, the old tank wasn’t always removed. Here’s a plain-language look at why that matters, what the state actually says, and where an oil tank sweep fits in.
Why an old oil tank still matters
According to the New Jersey Department of Environmental Protection (NJDEP), older home heating oil tanks, whether underground, aboveground or in the basement, can rust and leak over time and contaminate soil or groundwater.
There is also a practical side. The NJ Department of Community Affairs notes in Bulletin 95-1B that even previously abandoned tanks are increasingly being removed, driven by insurance and mortgage companies that don’t want the liability these tanks may pose. An unknown tank can become a lender or insurer question right before closing.
What New Jersey actually requires (and what it doesn’t)
This part often gets exaggerated. NJDEP’s Unregulated Heating Oil Tank (UHOT) FAQs explain that residential heating oil tanks are considered “unregulated,” and that if there is no indication of a discharge, there is no state requirement that the tank be removed. The same page notes that real estate and other professionals often recommend removing a tank before a home is sold, and that if a leak is discovered during removal, cleanup is required.
At the federal level, the U.S. EPA excludes tanks storing heating oil used on the premises from its underground storage tank rules and points homeowners to state and local agencies.
Other points worth knowing:
- Closing an underground residential tank, whether it’s removed or abandoned in place, must be done by a contractor certified for tank closure, according to NJDEP’s Homeowner’s Guide to the UHOT Program.
- Under DCA Bulletin 95-1B, removing or abandoning a tank requires a demolition permit from the municipality, and the fill and vent pipes must come out too. The bulletin describes oil being delivered into basements or the ground through fill pipes left behind.
- If a leak is found, NJDEP says it should be reported to the DEP Hotline at 1-877-WARNDEP, and the cleanup must be handled by a certified Subsurface Evaluator or a Licensed Site Remediation Professional (LSRP).
This article isn’t legal advice. Your real estate attorney is the right person to explain who is responsible for what in your contract.
Clues that a home may have had an oil tank
Our inspector looks for the small details that hint at an oil heating past, such as:
- A fill pipe or vent pipe sticking up near the foundation or out in the yard
- Cut or capped oil supply lines coming through the basement wall or floor
- An older oil burner, or a newer gas system in a house old enough to have started out on oil
NJDEP also lists warning signs that an active tank may be leaking, including an unexplained jump in oil use, water in an underground tank, ongoing burner problems, staining on basement walls or floors, an oil sheen in a sump or French drain, and fuel oil odors away from the burner. NJDEP suggests calling your heating service company first, then a DEP-certified environmental professional.
What an oil tank sweep does (and doesn’t) tell you
An oil tank sweep is a non-invasive scan of the property to look for signs of a buried tank. Our team’s equipment includes ground-penetrating radar (GPR), and nothing gets dug up. A sweep can help answer, “Is there likely a tank here, and where?”
What a sweep can’t do is tell you whether a tank has leaked. If a tank is found, the next step is usually a conversation with a NJDEP-certified tank professional, who can explain options such as soil testing, removal or closure. Finding out during your inspection window gives you and your attorney time to plan.
Tips for sellers and agents
If a tank was already removed or closed, paperwork is your friend. NJDEP suggests contacting the municipality and filing an Open Public Records Act (OPRA) request for any tank removal permits on the property. If a past leak was cleaned up, NJDEP issues a No Further Action (NFA) letter, and its status can be looked up by site address through NJDEP’s Data Miner. If a tank was closed with no sign of a leak and passed the municipal inspection, NJDEP notes that no NFA letter is needed, so the closure permit and contractor’s documentation are what buyers will want to see.
Sellers who know a tank is still in the ground may want to talk with their attorney and a certified closure contractor before listing. A pre-listing sweep can also take the surprise out of the buyer’s inspection.
One note on funding: the state’s Petroleum Underground Storage Tank Remediation, Upgrade and Closure Fund can provide grants or loans for eligible leaking residential tanks, but NJDEP says new applications are currently being date-stamped and held until funding is available, and applications for non-leaking tanks have not been accepted since 2011.
Adding a sweep to your inspection
An oil tank sweep can be added to your home inspection or booked on its own. It pairs easily with our other services in one visit: a full home inspection with drone roof inspection, radon testing, termite/WDI inspection, sewer scope, mold testing and septic inspection. Free warranties are included with every inspection.
We serve about half of New Jersey, from roughly 20 minutes south of Toms River north to the Pennsylvania and New York borders.
