If you are involved with an oil tank removal project, it is probable your first tank removal and likely your last. The odds of you making the best decision are slim. Let’s agree that the best tank removal is one where the tank does not leak and you don’t have to remediate.

That said, you could expect a cost for tank removal on average to be about $1,500.00. This cost entails the time to get permits, equipment and labor to excavate the tank, trained personnel to cut open and clean the tank, oil recovery, tank removal, soil sampling, backfill material and labor and ultimately a report from the company so you can document the tank removal. The tank report is completed weeks after removal and is performed in an office utilizing the notes and data collected from your site. Sounds like a lot for $1,500.00, well it is.

Let’s talk about what makes your tank removal the best tank removal.

Your cost is close to the average cost of $1,500.00. Why, well the firm that sells these services has to do the work at a market rate where they can make money. Otherwise, they are offering the work at a loss, with the plan that they will make the money on the backend, which is the remediation and even a small remediation can cost over $5,000.00. You get what you pay for, remember that.

If you buy a house that had an oil tank, you want to know that the tank did not leak. The only way to know that is if you have testing completed. Being the owner of the tank you may think you do not want to have testing done, or else you may find a problem. After 25 years of dealing with tanks the bottom line question everyone wants to know is if the tank leaked. Buyers and sellers because that answers can make or break a real estate transaction. Bottom line tank soil samples when the tank is removed

Why do many contracts for tank removal not include soil sampling? Short answer, it is cheaper. Soil samples cost $120.00 on average and with two soil samples being the average number acquired sampling can raise the cost by $240.00, plus the time to write a report that talks about the test results. Look, you are removing an old buried metal object, you are fooling yourself if you don’t think that rust and extensively has not occurred to the tank. Your low cost tank removal company is counting on this and will be happy to give you a cost to remediate the tank once contamination is discovered.

Why do many contracts not include a report of the tank removal? Cost again is the culprit. If you write a report you need someone present during tank removal that will be taking notes, photos, soil samples and will eventually sit behind a desk to type a report. That all takes time and there is a cost involved. Bottom line make sure the contract includes a report.

Tank removal site assessment soil samples when acquired for independent laboratory analysis provides quantitative not qualitative data. New Jersey and Pennsylvania have one comparative standard for number two heating oil in soil and that is by laboratory analysis. Visual, oil water agitation or olfactory evaluations have no standards so you have no foundation to lay an opinion.

Residential tank removals do not specifically require that you obtain soil samples. This conflicts with the interest of a purchaser (mortgage or insurance underwriter) for a site when hard data is requested. Legally you do not need to test, if a buyer wants to test prior to purchase it is their due diligence and hence their cost. Obviously it is less expensive to acquire samples from an open excavation at tie of removal, as opposed to post removal and backfilling.

What is the best tank removal? The best is one where testing and a report is provided as part of the tank removal. It is what is required for commercial sites, so why wouldn’t you do the same for a residence?

The purpose of this document is to provide a concise reference to the preferred practices and procedures for oil tank removals in NJ. 

oil tank removal nj 

Buried oil tanks raise a variety of environmental, safety, legal and economic concerns for home owners and home buyers. The largest concern relates to the environmental issues that are caused when the oil tank leaks and causes  soil or groundwater  contamination. 

The following is a breakdown of the proper steps that should taken in order to remove your residential oil tank. 

Step 1: Permitting 

Local construction/demolition and/or fire subcode permits need to be applied for and the permits approved by the municipal office.     Once the local permits are approved, it is typical that the local inspector will need to be onsite for all or a part of the removal activities.  Permit application, insuring permit approval and scheduling of local inspectors is always done by Curren Environmental before removing the oil tank. 

Step 2: Underground Utilities 

State law requires that before any excavation activities can commence, a utility markout will need to be performed. The company performing the oil tank removal should call for an underground markout through “NJ One Call”.  t is the law in New Jersey and other states, to call for a utility markout before you dig. Make sure the company you choose to remove the tank obtains a markout confirmation number.  It protects all parties involved. 

Step 3: Oil Tank Cleaning 

Cleaning of the tank will consist of wiping, squeegeeing and removing all liquids and sludges from the tank.  Liquids are then either  placed into onsite storage containers or a vacuum truck. . 

Step 4: Oil Tank Removal    

It is recommended that all oil tanks be removed from the ground  when taking a tank out of service.  (In some instances when removal of the oil tank may damage the integrity of the structure an abandonment in place can be performed.)  By removing the tank from the ground a site assessment can be performed to determine if the tank has maintained integrity. 

Step 5: Oil Tank Site Assessmen

After the oil tank is removed a site assessment can performed by Curren’s certified NJDEP Subsurface Evaluator.  The site assessment to evaluate whether contamination is present in the excavation can be carried out in a variety of ways  while the tank is being removed. 

▸   Evidence of contamination can be determined from product odors, product stained soils, and/or visual evidence of free product.   

▸   Inspection of the Underground Storage Tank, (UST), for evidence of corrosion or perforations. 

▸   By a series of observations and measurements during the tank excavation and decommissioning operations such as  soil and ground water sampling and analysis. 

In New Jersey the standard analytical testing method for #-2 heating oil is Extractable Petroleum Hydrocarbons (EPH). All samples must be submitted to an independent NJDEP licensed laboratory for analysis.  EPH results are measured in part per million or ppm. Samples results above 5,100 ppm are actionable and require remedial activities to be completed.   EPH results  between 1,000 ppm and 5,100 ppm require an additional analysis. 

Step 6: Backfilling 

Once the tank is removed from the ground the void space must be backfilled with clean certified  fill.  The general equation for backfilling is five cubic yards of backfill material for every 1000 gallons of storage capacity.  For example a 500-gallon tank would require 2.5 cubic yards of fill material.  Suppling and installing the backfill is always performed by the firm removing the tank and should be included in tank removal cost. 

Step 7: Site Investigation Report - Tank Certification

Curren Environmental will prepare a Site Investigation Report which will document the tank removal activities.  The report will detail the heating oil tank removal and provide certification of the tank removal.   The report will include the following information: 

   1.  Copy of the local permit for tank removal 
   2.  Liquid receipt from the tank cleaning. 
   3.  A thorough written description of the tank removal activities. 
   4.  Photo documentation of tank removal (if available). 
   5.  A copy of the tank scrap receipt. 
   6.  Any applicable laboratory test results. 
   7.  A detailed text description of the condition of the tank and if any petroleum contamination was noted in the tank excavation. 

Curren Environmental, Inc. is a licensed by the  New Jersey Department of Environmental Protection (NJDEP) to perform closure activities associated with Underground Storage Tanks, (USTs).
