Underground Oil Tank Removal In Paramus, NJ

A residential buried tank in this area is usually 275, 550 or 1,000 gallons of steel sitting two to five feet down, most often in a side yard, under a driveway or against the foundation wall it once fed.

Almost all of them here are out of service. Paramus has 60 households still heating with oil against roughly 5,300 homes built before 1970, so the tank being dug up has generally been idle since the property converted to gas.

An idle tank is not an empty one. Decades of sitting separates the remaining fuel, and the heavy fraction at the bottom is what makes an abandoned tank more work than a live one.

New Jersey restricts this specific work. An underground heating oil tank has to be removed by a closure-certified individual working for a closure-certified UST firm, which is narrower than the trades permitted to take out an above-ground tank.

Where a discharge is found, the list narrows again to a certified Subsurface Evaluator at a UST-certified firm or a Licensed Site Remediation Professional, with the individual and the firm both holding current certification.

It is worth asking any contractor which of those they hold before work starts rather than after.

Access decides more of the price than the tank does. An open side yard with room to work is the straightforward version, and it is the version the cheaper published ranges describe.

What sits on top is the expensive variable. Concrete, asphalt, pavers, a deck or a patio has to come up and go back, and reinstating a driveway can cost more than moving the tank did.

Proximity to the house is separate again. A tank close to a foundation limits how the excavation can be cut and battered, which slows the dig whatever the surface is.

Whatever fuel and sludge remain come out first, and they leave the site as regulated waste rather than as scrap.

The tank is then cut open and cleaned so it can be handled and hauled as steel. That is what turns a sealed vessel of unknown contents into an inert object a yard will take.

The disposal record from that step is one of the two documents worth keeping, and a buyer's attorney will ask for it years later.

The municipal inspection happens with the excavation still open, and it is the moment the job splits in two. Until the tank is lifted nobody has seen the ground it was sitting on.

A clean result means the hole is backfilled and the file closes on the permit and the disposal record. A discharge means a reporting obligation and a regulated cleanup with its own rules about who may do the work.

This is why a quote states soil work as an exclusion with published ranges beside it rather than as a number. Anyone giving you a firm contamination figure before the dig is guessing.

A clean excavation is backfilled and compacted, and the surface is put back to what was there before, which is lawn on most Paramus jobs and hard surface on the rest.

Reinstatement is the part homeowners underestimate. Matching an existing driveway or patio is its own trade and its own cost line, and it should appear in the quote rather than surfacing afterwards.
