Oil tank removal in every Mercer County municipality
Mercer County
The oil tank removal work we do across Mercer County
Residential heating oil tanks, in every one of the twelve municipalities. Licensed, NJDEP-certified New Jersey tank contractors carry out the work, file the municipal permit and meet the subcode official on site. Most standard removals are one day on site.
Underground tank removal
The standard job. Permit, markout, pump and clean, excavate, lift, inspect, sample, backfill and restore. One day on site, with a written closure report at the end.
Tank sweeps
Ground penetrating radar and a magnetometer, then a probe rod to confirm. This is the call to make when you do not know whether a tank is there, or a buyer has asked.
Closure in place
When excavation is genuinely not feasible, the tank is pumped, cleaned and filled under the same permit and the same inspection. We will tell you honestly when this is the right call and when it is not.
Remediation and NJDEP closure
If the samples come back dirty we excavate and dispose of the contaminated soil, re-sample until it is clean, and run the NJDEP file through to formal closure.
What every job includes
This is what is in the price, on every removal, in every town. If a quote you have been given elsewhere is missing any of it, ask why before you sign.
- Municipal permit filed with your town construction office
- NJ One Call (811) utility markout
- Pumping and disposal of remaining oil, water and sludge
- Fill and vent lines cut and sealed
- Excavation, tank lift and scrap disposal
- Inspection witnessed by your town construction or subcode official
- Soil samples from the excavation, sent to a certified laboratory
- Clean backfill, compaction and restoration to grade
- A written closure report with lab data, permit sign-off, disposal receipt and photographs
Working to a closing date
Most of our calls come during attorney review, after a sweep has come back positive and a closing is already booked. A clean removal runs about 7 to 12 business days from first call to final paperwork: one day on site, then five to ten business days for the laboratory. Where a closing is tight we can often compress that to 5 to 7 days. Tell us the date when you call and we will work to it, or tell you plainly if it cannot be met.
If the tank has leaked, the timeline changes. Excavation is usually one or two days, but formal NJDEP closure normally takes three to six months, and no contractor can shorten that. In that situation the usual fix at closing is an escrow holdback, and we will give you a written scope your attorney can work from.
Oil tank removal rules that apply in all 12 towns
This part is state law, so it does not change when you cross a town line.
- A demolition permit is required for removal or abandonment of a tank, whether or not it is part of any other work
- The application must include a sketch showing where the tank is
- The fire subcode official does the plan review and the inspection, under N.J.A.C. 5:23-3.4
- Fill and vent pipes must come off when the tank is removed or abandoned
- Six closure methods are recognised, from aboveground removal through to fill with sand or inert material
- The fill methods may not be suitable where groundwater is high, because an empty filled tank can float
That last rule is the single most useful thing on this page for anyone in Yardville, Groveville, Titusville, the low blocks of Hightstown, or anywhere near the Delaware. If you were planning to fill instead of remove to save money, the water table may make that decision for you.
Oil tank removal permits: what changes town to town
If you have a closing date, these are not trivia. A Friday 11am inspection cutoff in Robbinsville is the difference between finishing that week and finishing the next one.
| What varies | Why it matters to you |
|---|---|
| The permit fee | Each town sets its own schedule. Ask your contractor what yours will be rather than assuming a county-wide number. |
| Paper filing or an online portal | Ewing, West Windsor and Hopewell Township use the SDL portal. Robbinsville uses GovPilot eforms. Pennington was still on paper with an online system listed as coming. |
| How you request an inspection | Robbinsville requires it in writing by 2pm Monday to Thursday and 11am Friday. Hightstown requires email or a PDF form. Ewing wants three preferred dates in the email. |
| Office hours | Robbinsville closes at 3:30. Ewing at 4:00. West Windsor runs 9 to 5. |
| Who signs off | Named fire subcode officials differ. |
Mercer County oil tank removal FAQ
Which town office do I call?
Your municipality’s construction office, and specifically the fire subcode side of it, because the fire subcode official reviews and inspects tank closures under N.J.A.C. 5:23-3.4. Your contractor normally files it. Your town page has the address, phone and filing method where we have confirmed it.
Does Mercer County issue the permit?
No. Mercer County does not issue construction permits for this. It is municipal, which is exactly why these pages exist separately.
Can I fill the tank instead of removing it?
Sometimes. State guidance recognises three fill methods alongside removal, but notes they may not suit high groundwater areas because a filled tank can float. If you are on low ground near the Delaware, Crosswicks Creek, Rocky Brook or Peddie Lake, ask about the water table before you assume filling is an option.
I am in a newer development. Do I even have a tank?
Possibly not. Post-1970s subdivisions across Robbinsville, West Windsor and East Windsor were generally built on gas rather than oil. Check your build year and your heating history before paying for anything. If you cannot establish it, a sweep at $150 to $400 settles the question.
