Residential Oil Tank Removal FAQ

New Jersey

If you own a home in New Jersey, you may have questions about underground oil tanks. Oak Environmental has helped thousands of homeowners, estate executors, and sellers handle tank removal and cleanup in full compliance with the New Jersey Department of Environmental Protection (NJDEP).

How do I know if I have an underground oil tank at my house?

If your home used oil heat and was built before the 1990s, there is a chance an underground storage tank (UST) was installed. Oak Environmental can perform a tank scan using ground-penetrating equipment to determine if a tank is present.

What happens if my underground oil tank leaked?

If a tank has leaked, contaminated soil must be removed and tested. If the leak reached groundwater, additional investigation may be required. Oak Environmental manages cleanup and coordinates with the NJDEP so you receive the proper documentation.

Do I need soil testing after a tank is removed?

Yes. NJDEP recommends and most buyers require post-removal soil sampling. Testing confirms whether the area is clean and provides written proof to avoid problems during sale or refinancing.

What are the signs of a leaking oil tank?

Possible indicators include:

• A fuel oil smell in soil or basements

• Stained or discolored soil near the tank area

• Dead or stressed vegetation above the tank location

• Lab test results confirming petroleum contamination

• Using more oil year after year

• Issues with heating system, especially water in line

Because leaks are not always visible, laboratory testing is the only way to be sure.

Can I sell my house if the tank leaked?

Yes, but buyers and lenders will require proof of cleanup. The NJDEP issues a No Further Action (NFA) letter or a Licensed Site Remediation Professional (LSRP) can issue a Remedial Action Outcome (RAO) to confirm the site is compliant. This documentation protects the seller and reassures buyers.

What if my tank was removed years ago but no soil testing was done?

You may still need testing today, especially if you are preparing to sell. Oak Environmental can sample the soil and, if necessary, help you obtain NJDEP closure documents so the property is marketable.

How long does tank removal and cleanup take?

• Tank removal only: usually 1 day.

• Cleanup after a leak: typically 1 day depending on how much soil is affected.

Will I be penalized if my tank leaked?

No. NJDEP does not penalize homeowners for past leaks if they are properly addressed. As long as the contamination is reported and cleaned up according to regulations, you will remain in compliance.

How much does residential tank removal and cleanup cost in New Jersey?

Costs depend on tank size, accessibility, and whether contamination is present. Simple removals may cost only a few thousand dollars, while cleanups requiring excavation or treatment will be higher. Oak Environmental provides clear, upfront estimates before work begins.
