So here's the story...a hired tank removal company was found on the first page of Google, they had the cheapest price.  A tank was found to have a hole after it was removed from the ground.  No evidence of oil contamination was present in the soil, meaning staining or odors of petroleum in the tank grave.  Due to the hole the NJDEP hotline was called and a case number was obtained.   Removal company acquired one soil sample for laboratory analysis, which was found to have a level of ND (Non Detect).  After removal, client was billed almost double the quoted amount and then told they would have to spend another $3,600.00 to close out the called in NJDEP case number, even though the tank did not leak (Soil sample was non detect).

This was the story that was explained to our office.   Curren reviewed the removal contract, soil laboratory test results and the subsequent proposal for $3,600.00 to do additional testing.  It was at this point that it was clear to Curren Environmental that the property owner did not have to do anything and was being taken advantage of.

The property owner hired a removal company without doing the proper research and inturn getting taken advantage of - these are the mistakes the owner made:

  • Owner went with cheapest price, which is really getting what you paid for. When you compared the quotes there was a difference between the hired company’s cost and the next one.  We often see these low cost quotes try to make up the difference by selling additional services that are not typically warranted.  Keep in mind a tank removal is perhaps a once in a life time decision.
  • The tank removal contract had no reference of taking any soil samples after removal, even though there was a chance the tank may have been found to be leaking.
  • Going back to item 2, there was no explanation regarding if testing was performed what would constitute a good or bad results. Results of Non Detect (ND) requires no further testing. 
  • The contract did not include any report. If you were buying a property that had a tank removed, wouldn’t you want a report about the removal?

In this case, the soil test was clean and the tank company said more testing was required, the owner was confused as to why more testing was necessary.  Curren thought it possible that a case number was obtained due to a hole in the tank, which may not have discharged any oil as the hole may have not fully appeared until AFTER removal from the ground.  It is confusing that if the tank leaked that your soil sample is clean. 

We asked the owner to question the need for further testing, their response was as follows:

Unfortunately NJDEP regulations state that if there are holes in a tank then a case number is required.  Even if contamination is not found in the ground, the potential for contamination is cause for a case number. 

Soil samples for closure are required to be collected by a NJDEP licensed subsurface evaluator.  Once the samples are collected and returned from the laboratory, a report can be generated to close out the case number. 

We cannot provide any letter stating there is no contamination or closeout the case with NJDEP without the required samples that must be collected by a NJDEP subsurface evaluator.

The only time sampling is not required is if the tank passed inspection and was not considered a leaking tank. 

Have an Environmental Issue? 

Their response is misleading.  Yes a hole in a tank can be cause to report a spill, but if you acquire a soil sample and it is clean, you have proven that the hole did not create a discharge to the environment.  The NJDEP can be contacted and explained to that the spill reported was in error.   This is what was ultimately done with Curren’s assistance and no further monies were spent.

Curren explained that no testing is required by law for a tank removal and the contract clearly does not include any contingency for sampling the tank excavation after removal and what the results would mean.    Testing is important to prove the tank did not leak and should have been included as an option in the quote, it was not.

Changes to the NJDEP & EDA Tank Grant Effective September 15, 2011

Grant applications that have already passed NJDEP review and have been submitted to the EDA are now being processed by the EDA with the monies added to the Grant Fund from the 2012 State appropriation.   These applicants who had submitted their grants prior to the May 3, 2011 fund change  will be receiving notification from the EDA over the next few weeks.

Applications that are in-house at the EDA but incomplete will be reviewed and processed in the order that they were received and held until sufficient funds become available.

There is a priority system that is in place pertaining to which applicants get funding first as per NJSA 58:10A-37.4, which is as follows:  

1) Applications indicating a discharge posing a threat to drinking water, human health or sensitive ecological area;

2) Supplemental applications for remediation of discharge from regulated tanks;

3) Applications for remediation of discharge from regulated tanks;

4) Supplemental applications for remediation of discharge from unregulated tanks;

5) Applications for remediation of discharge from unregulated tanks;

6) Non-leaking tank applications

Within each of these categories, priority is based on the application filing date and processing dates that EDA staff adheres to when conducting its review.Click me

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).
