Q:             My tank leaked. What do I do now?

A:              First, you must contact all applicable insurance companies (homeowners, tank, etc.) and alert them of the situation so they can open a claim number for you. Second, you are required to contact the New Jersey Department of Environmental Protection (NJDEP) to report the leak and receive a case number. Third, contact a licensed environmental professional (like The Entech Group, Inc.) to determine the next best course of action.

Q:             Do I need to be home during the removal or installation of my oil tank?

A:              Yes, residents need to be home for both an oil tank removal and aboveground oil tank installation. Our crew will need access to the oil lines inside the home in order to get the new tank in working order.

Q:             How long does a tank removal and installation take?

A:              It will typically take one day for each service.

Q:             If Entech removes the tank and it leaks, what does Entech do?

A:              We will first inform you (the homeowner) of the problem and advise them to call both their insurance company and the New Jersey Department of Environmental Protection (NJDEP). After this, we talk with the homeowners and go over their best options regarding soil sampling and remediation.

Q:             Do you remove the tank from my property or do I need to dispose of it?

A:              If the tank has no visible holes and passes inspection from your local government official, Entech will remove of the tank that day. However, if tank has holes and fails inspection, we recommend leaving it on the property for the homeowner’s insurance company to investigate.

Q:             After my tank is removed, what happens to the hole left behind?

A:              The hole left behind will be filled with certified clean fill material.   The rest of the excavation is topped off with the soil previously positioned above the tank.

Q:             Is it better to remove an underground tank or abandon it in place?

A:              Entech recommends removing your oil tank in most situations in order to reduce your environmental liabilities.

Q:             Are there different sizes of aboveground storage tanks?

A:              Yes. It depends on if you choose to go with a single or double wall tank, but the most common sizes are 275-, 330- and 400- gallons.

Q:             Where can an aboveground storage tank be placed?

A:              An aboveground storage tank can be installed on the inside or outside of a home, so long as the tank’s vent is at least two feet away from a window or doorway and the tank’s body is at least five feet away from a point of ignition (such as a water heater or furnace).

Q:             Can you transfer oil from one tank to another?

A:              We do our best to transfer as much oil as possible. However, there is always some amount of sludge along the bottom of your oil tank that must be disposed of because it cannot be transferred.


Q:             Who contacts my insurance company?

A:              The homeowners are responsible for contacting their insurance company prior to the start of the services.

Q:             How do I know if my homeowner’s policy covers a leaking tank?

A:              It is the homeowners’ responsibility to contact any tank or homeowner insurance companies to obtain information regarding their tank coverage.


Q:             Who is eligible for a grant?

A:              Update: NJDEP Oil Tank Grant Program – Paused

As of May 4th 2011:

The Entech Group received a letter May 3rd, 2011 from the NJEDA / NJDEP concerning the UST Grant Program which was distributed state-wide to companies certified to perform oil tank removals in NJ. The subject of their letter was “The Petroleum Underground Storage Tank Remediation, Upgrade and Closure Fund (UST Fund)”. This program was greatly beneficial to homeowners looking for underground oil tanks removal in NJ because you were able to get tank removal services at little to no cost. The letter explains that there are insufficient funds for the program, and as a result there is a hold and possible cancellation of the grant funding programs. Effective May 3, 2011, new UST Fund applications for the non-leaking tank program will not be processed, however, applications for the leaking tank program will be date stamped and held until if and when sufficient funds become available.
