In the United States people would initially heat their homes with wood up until the early 1900's. Then the use of coal became popular from 1920 to 1940,  and then oil heat was king post WWII. Natural gas came into play in the 1990s  and finally natural gas (1990's).   Homes built pre-1990 have a high probability that oil was a fuel source at one time.  After World War II oil was plentiful and cheap,  the United States was a steel-making machine.      Cheap oil and industry-dominating steel production = heating oil tanks, buried and above ground for commercial and residential properties.

As of today, oil has been replaced largely by natural gas that is piped into homes which removes the need for calling for oil delivery to fill up a tank.  When neighborhoods that originally never had natural gas were piped for gas homeowners slowly upgraded as their heaters needed replacement.  What happened to the oil tanks? For the most part, they were abandoned, disconnected from the heater, and left where they were buried in the ground or in a dark corner of the basement up to about the mid to late 1980s.   In the 1990s some tanks were removed, some were abandoned in place by filling with an inert material like sand, concrete or foam and some were simply left where they were.

Photo Aug 15, 11 06 40 AM-1This brings us to today why should anyone be concerned about an oil tank, oil comes from the ground.   Well, New Jersey has no past or present drilled oil wells, we are not an oil-rich state, simply put oil is not naturally present in the ground in New Jersey.   What we are burdened with are regulations.   Yes, there are regulations governing oil tanks.  The most broad-reaching regulation is the Spill Act from the 1970s which says any release of a contaminant to the environment is reportable to the New Jersey Department of Environmental Protection (NJDEP).   On top of this law are regulations that dictate what amount of oil is permissible and what is not.  Levels above what is permissible require what is known as remediation.   Other laws are construction defining what you must do to a tank when you remove it from service (either remove it or clean and abandon it in place).   You are also burdened with the definition of a Responsible Party (RP).  An RP is kind of like a store policy that says you break it you buy it.  In terms of an oil tank that leaks and requires remediation, well if you own a property or buy a property with an oil tank that leaks, well you are responsible for addressing it, hence the Responsible Party term.  This is why home buyers are wary of oil tanks.  This is why homeowners selling a property with an oil tank have problems, nobody wants to have the financial burden of cleaning up an oil tank leak.   Let me add another layer to this, banks, and mortgage companies are wary of providing financing for a home purchase if an oil tank was or may present.  Oil contamination can and has devalued homes, somewhere it makes sense for homeowners to walk away from the mortgage, leaving the bank with the problem.

Best Oil Tank Removal

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 $1,800.00. 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 $1,800.00, well it is.

 Best oil tank removal

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

Your cost is close to the average cost of $1,800.00. 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 small remediation can cost over $8,000.00. 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 have 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, and soil samples and will eventually sit behind a desk to type a report. That all takes time and there is a cost involved. The bottom line make sure the contract includes a report.

Tank removal site assessment soil samples when acquired for independent laboratory analysis provide quantitative, not qualitative data. New Jersey and Pennsylvania have one comparative standard for number two heating oil in the 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 the 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 are 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?Call Curren Today

Oil Tank Removal New Jersey

You recently had your oil tank removed and there were holes in the tank. However, there are no indications of soil contamination but the company that removed the oil tank filed a report to the New Jersey Department of Environmental Protection (NJDEP). You are unaware that you may have been naïve in choosing your oil tank removal company due to the fact that removing an oil tank hopefully would be a once in a lifetime event. At this point, you understand that clearly your tank removal contract should have included soil sampling, but it did not. You are also unaware that soil sampling must be completed, then the report is sent to NJDEP to close out the case number (assuming that it meets the state parameters for acceptable oil levels) and rescind the remedial action. 

residential oil tank removal

Regarding what soil sampling is and how it is performed, there are permissible levels of oil that can remain in the ground and conversely there are levels that would require remediation. New Jersey regulations require that upon removal of an oil tank that has evidence of a leak, you are to obtain a minimum of 5 soil samples from the tank excavation (5 for a 500 gallon tank and 6 for a 1000 gallon tank). This is relative to your contract for tank removal. If the contract did not reference soil sampling, you can’t guarantee soil samples would be obtained. Soil samples are critical to assess the tank excavation for petroleum levels. The testing is meant to inform the property owner if indeed oil levels are present and remediation is warranted or that levels are within permissible limits and can be left in place. Now, you, as the owner of the oil tank that leaks can make an informed decision regarding remediation. 

If your tank removal contract does not include costs for soil sampling or discusses the possibility of finding a tank leak, it is pretty safe to assume that the tank removal company is looking to find a leaking tank and remediation.

In a situation where a tank is removed, found to be leaking and no soil sampling was performed, you should be concerned as to whether the soil needs remediation. All discharges are required to be reported to the NJDEP (If your tank contract doesn’t inform you that a tank leak is reportable, think again about who you are hiring).

oil tank removal New Jersey
Example of soil testing by soil borings


The only way you would know if your tank leak has petroleum contamination in the soil above or below NJDEP permissible limits is to have soil sampling performed. If all your samples are in compliance with NJDEP regulations you will receive a No Further Action (NFA) letter that will close out the NJDEP case number. This can be performed without having to perform actual remediation, which is typically soil removal.

Again, the tank removal contract should have addressed obtaining soil samples and what to do if a leak was noted. Remember, holes are never good in an oil tank and you rarely will see physical evidence of an oil discharge in a tank excavation, meaning you are not going to see oil or stained soils.

Is my residential heating oil tank regulated in New Jersey?

Is my residential heating oil tank regulated in New Jersey?

 

Heating oil tanks are unregulated by the NJDEP in New Jersey as they used to be called UHOTs (Unregulated heating oil tanks).   Work performed on abandoning an oil tank is governed by the New Jersey Department of Community Affairs (DCA) Bulletin No.: 95-1B. Discharges or leaks from these tanks are regulated by the  Department of Environmental Protection’s Unregulated Heating Oil Tank (UHOT) Program.

 NJ oil tank removal

Let us not get ahead of ourselves.  First, to work on a heating oil tank in New Jersey you must be licensed by the NJDEP. The NJDEP certifies individuals and firms that perform services on unregulated heating oil tanks.  To be technical, N.J.A.C. 7:14B defines unregulated heating oil tanks as, “any one or combination of tanks, including appurtenant pipes, lines, fixtures, and other related equipment, used to contain an accumulation of heating oil for on-site consumption in a residential building, or those tanks with a capacity of 2,000 gallons or less used to store heating oil for on-site consumption in a nonresidential building.”

To say it in English and following a federal definition, an underground storage tank is defined as a tank the volume of which, including the volume of the appurtenant pipes, lines, fixtures and other related equipment, is 10 percent or more below the ground.

It is generally recommended that if you own out-of-service underground heating oil tank, it is a good practice to remove the tank.   Takes removed from service such as during gas conversions, rarely ever get placed back into service.   Tanks older than 20 to 30 years are also recommended to be removed as nothing lasts forever. Although tank abandonment is allowed, there has been an increase in previously abandoned tanks being removed. These tank removals are driven by insurance and mortgage companies that do not want the liability associated with underground heating oil tanks, as these tanks can leak and remediation can be thousands of dollars.   

 Tank previously abandoned in place with sand

New Jersey has construction codes and The Uniform Construction Code (UCC) covers oil tanks, but this code is not a retrofit code, and therefore, it does not deal with tanks that have been abandoned for extended periods of time. The UCC applies when a tank is taken out of service as part of a construction project or when the tank has become unsafe. If a project results in an underground tank being out of service for a period of one year, (such as an oil to gas conversion), as per Section 5704.2.13.1.3 of the International Fire Code (IFC), the tank must be removed from the ground in accordance with Section 5704.2.14 of the IFC or abandoned in place in accordance with Section 5704.2.13.1.4 of the IFC. If an aboveground tank is out of service for a period of one year, as per Section 5704.13.2.3 of the IFC, the tank shall be removed in accordance with Section 5704.2.14 of the code.

An oil to gas conversion is an example where a construction activity can trigger the need to address the oil tank.  In this case, the local code officials must ensure that the tank is properly removed or abandoned in connection with the conversion.*

 oil to gas conversion

* The only exception to this would be where the owner can demonstrate a legitimate continued use of the tank.

 

The removal or abandonment of a tank requires an application for and the issuance of a demolition permit regardless of whether it is in connection with other related work. In short, if you are removing or abandoning an oil tank you need a permit.

 

Oil tank removal and abandonment inspections are the responsibility of the of the fire sub-code official as per the IFC, Section 5704.2.13, fuel oil storage systems, as referenced by the International Mechanical Code (Section 1301.5) and the International Residential Code (Section M2201.7). Per N.J.A.C. 5:23-3.4.

 

Proper Abandonment Procedures are detailed in the International Fire Code, Section 5704.2.13.1.4, the American Petroleum Institute (API) Bulletin 1604, and National Fire Protection Association (NFPA) 30 Annex C relating to the abandonment of underground storage tanks. These documents, which detail procedures for tank abandonment are followed by New Jersey’s applicable regulation as listed in N.J.A.C. 5:23-3.6.

 

Tank Leak Assessment

The construction regulations are not clear regarding who, what, when or how the assessment of a tank for leaks is performed as it is generally not considered a construction activity.  The construction regulations do define that WHEN contamination is found it is to be reported to the NJDEP hotline at 877-927-6337 (877-WARN-DEP).  This is the bear trap owners of tanks face when a tank is removed.  NJDEP regulations chapter 26F HEATING OIL TANK SYSTEM REMEDIATION RULES  Statutory Authority N.J.S.A. 13:1D-9, 58:10-23.11 et seq., 58:10A-1 et seq., 58:10A-21 et seq., 58:10A-37.1 et seq., 58:10B-1 et seq., and 58:10C-1 et seq.  Date last amended August 6, 2018, state that:

 

"Upon discovery of a discharge, the owner shall immediately notify the Department by calling the Department Hotline at 1-877-WARNDEP (1-877-927-6337)."

Therefore, under the NJDEP requirements the owner upon discovering a tank leak must notify the NJDEP spill hotline.

residential oil tank leak

 

Construction Permit Approval

 

The most misunderstood part of the tank closure process is the sign off from the local municipality.  As per the New Jersey Department of Community Affairs (DCA) Bulletin No.: 95-1B after tank has been removed and properly disposed of, and the excavation is filled with certified clean material, a certificate of approval can be issued by the local construction office and the permit can be closed out.    So once you follow the construction procedures the township can close the permit, if the tank leaked or not.  Again once, you remove and backfill the tank, the municipality is done with their job. Any remediation activity, including the removal of contaminated soil, will then proceed through the Department of Environmental Protection’s Unregulated Heating Oil Tank (UHOT) Program.

Does all this sound confusing?  It should not but it does and the layperson should not be expected to know these procedures or regulations but they are subject to them.

7 Things I wish I knew before I removed my oil tank.

 A construction permit is required and it can take up to 20 business days to get the permit, which is a month.

 I thought that my out of use tank could remain where it was buried.  Nope, the buyer of my house needed a mortgage and to get the mortgage to buy my house, the tank had to be removed. Their attorney also advised that it be removed.   Yep found this out 9 days before settlement.  Did not know the tank removal permit took weeks to get.   Settlement eventually happened but it was 4 weeks later.

 

home tank removal

 

A tank removal report is important.

Had my tank removed no leaks.  Listed house for sale, buyer wanted proof that the tank did not leak.  I had a copy of the contract for the removal and I had a paid tank removal invoice, that was not enough,. The company I hired to remove the oil tank did not give me a report.  Stupid me the contract for removal did not include a report.   I had to pay another company to dig up the old tank grave, test the soils, and give me a report that the tank did not leak.  Apparently, buyers want 100% confirmation that the tank did not leak.  I mean it makes sense you want a report of the tank removal if you are buying a house, but why didn’t the tank removal company tell me that or give me one? 

Tank removal soil sampling is really important.

I was told I did not have to soil test when the tank is removed.  Apparently, testing is not required by law.  Well I removed the tank and it leaked and the immediate diagnosis was $10,000.00 to $15,000.00 to remediate the leak.  When I mean immediate, I mean I had an estimate to clean up the tank leak 2 days after the tank was removed.   I ultimately fired the tank removal company and hired another company.  The new company told me that you could not conclude 100% if remediation is necessary without soil testing.   Bottom line I got the soil tested, yes there was oil; no, it was not enough oil to demand remediation.  Saved the $10,000.00.  Couldn’t the company tell me that testing while not required is worth it if the tanks appears to have leaked.

Not all oil leaks mean you have to remediate.

As I learned, a hole in a tank only means that the company that removed the tank is going to give me an expensive quote to clean up the oil.  Apparently there are legal amounts of oil that can remain in the ground, kind of like good and bad cholesterol, but you would never know unless you test.

 

Holes in oil tank, but oil in bottom of tank

How excited the tank removal company crew would become after they removed my tank and found out it was leaking.

Got my oil tank removed, took the day off from work. The whole thing was very stressful as I bought the house with a sand filed tank and now 10 years later I am selling the house and the buyers want the tank removed.   When the tank was removed and I saw holes in the tank, my heart sank.  The mood of the tank workers was elevated when they saw the holes in the tank   You would think the Philadelphia Eagles won a 2nd super bowl.   I feel like they were leading me down a path to spend money I didn’t plan for or have.   Look I understand tank leaks but I was never told about what happens when a tank leaks.  It was upsetting that they were happy for by problems.

Getting something in writing is really important.

I hired a tank company to do my tank removal.  They talked a good game and had a very good price.   They had a 2-page proposal, it was brief and somewhat vague now that I think about it.  Well when I found out my tank leaked soil testing which I thought was done or would be done (we did speak about it) was not done.  They actually took a soil sample but it was not for determining if the oil level in the ground was legal it for the disposal of the soil.  I was presumed guilty.    I was more than a little miffed; I didn’t want to pay the bill until I got a report of removal.  I didn’t get that either.  I complained to an attorney who reviewed my 2-page quote.  I was told if it is not in the contract the company doesn’t have to do it.  So, I got no testing and no report, but I was told I would if in the small chance my oil tank leaked.   It was a case of he said she said, the attorney agreed it was deceptive but not worth the money to go after legally.

The cheapest price is not the best.

I figured a tank is a tank is a tank, so a tank removal is a tank removal.  I picked the least expensive company.  I thought I compared apples to apples and was picking the shiniest apple.  Well my tank leaked and I was up charged more than 5 times what the cost to remove the tank was.    What I learned from one of the tank company workers who needed to use my bathroom was the company doesn’t make money removing oil tanks.  The cleanup is much more profitable and their goal is to get as many tank removal projects  as possible, which increases their odds of finding a leaking tank.   They are supposed to call the office once they know a tank leaked, I guess to toast to their good fortune but not mine.

These seven snippets of experiences all came from clients of Curren who had their tank removed by another company.

Do something once and you are a novice.

Do something twice, well you are not a pro but you know more than you did the first time.

Bottom line, we have been performing tank projects for over 20 years.  Thousands of tanks tested, removed, and remediated.   Referrals are our largest source of work and we don’t advertise, no ads on the internet promoting Curren Environmental.     We do get many calls from people who after reading our web site and speaking to us wished they called us first for their tank removal.

If you have a tank and you want solid advice and your work professionally done, call our office.  We provide free consultation and estimates.  We have no sales people and 20 years of satisfied clients.  You can be the next one.

How long does an Oil Tank Last?

What is the life expectancy of an oil tank?

How long does an oil tank last?  When do you replace an oil tank.  These are popular oil tank questions.  All things have a finite life expectancy. Both aboveground storage tanks (ASTs) and underground storage tanks (USTs) have a usable life. The problem is your tank can fail (holes appear) and you may never notice.  An industry average for the life span of an oil tank is 20 years, some tanks last longer and some shorter.  This time frame is greatly dependent on the type of oil tank, construction of the tank (meaning thicker walled tanks generally can last longer). environment the tank is in (indoor - outdoor),  and the contents of the tank.  Harsher environments tend to shorten the lifespan of pretty much anything, including steel tanks. 

 
my oil tank leaked

 

When I ask people how long they think a tank is supposed to last I typically get silence or "I don’t know".   Then, I tell them thank you for not saying "Tanks last FOREVER".   A simple rule of replacement is if the roof has been replaced, so should the tank.    This is for all the people who are using a tank TODAY and if your house was built between 1950 and 1995, your tank is beyond any reasonable expectation of usable life and should be replaced.  No there is not a likely possibility that the original tank from the day your house was constructed has been replaced.  The saying 'if it isn’t broken don’t fix it' is unfortunately followed when it comes to oil tanks.   Simply put, if people replaced tanks within a reasonable amount of time, you wouldn’t have tank leaks and expensive environmental cleanups.

How do oil tanks leak?  Many oil tanks rust through from the inside out.  This most often occurs when the oil is not present, meaning upper portion of the tank where the tank is empty and the oil is not present to lubricate the steel.  Tanks can also leak due to the use of low sulfur fuel.  Heating oil tanks that have low sulfur fuel and water can allow microbial growth to occur.  Secretions from these microbes can produce acids that can corrode a steel tank.

 

oil tanks can rust from the inisde

The photo above is the inside of a cleaned and cut open oil tank.   What is really interesting is the rust you see on the bottom of the tank.  This is the corrosive effect of the microbial activity in the tank.  Yes an oil tank can corrode from the inside of the tank.

 

 

Click Here to Learn about Testing Oil Tanks for Leaks

Aside from corrosion inside the tank, an oil tank can deteriorate from the outside due to environmental conditions.   Rust never sleeps and for corrosion to occur you need metal, oxygen and moisture.   How fast a given metal rusts is based on the environment the metal is exposed too. 

 

Holes in Underground Oil Tank

 

Aboveground oil tanks may look fine from a cursory exterior view but in fact, could heavy corroded on the inside and be ready to fail. 

Underground oil tanks are thicker than comparable aboveground tanks due to a more corrosive environment.  In short, an indoor rated AST is thinner than an outdoor rated AST, which is thinner than a buried UST.  Curren has found that there is a wide variation in indoor aboveground and outdoor aboveground oil tank life spans due to the considerable variation in both the quality and thickness of steel (older tanks seem to have been a heavier gauge steel), which helps prolong the life of the tank.

We have seen indoor oil tanks in good condition that are 60 years old or older, and we have found failures in newer oil storage tanks that may have been made of thinner or cheaper steel and that did not last as long as the original ones.  The tanks made immediately following WWII are of higher quality, saying things are not made as good as they used to be is a very true statement when it comes to oil tanks.

Rather than guess a tanks oil tank condition, we suggest that if your home has an older aboveground oil storage tank, twenty years old or older, you should replace the tank.  Keep in mind many brand new oil tanks have a 10 year warranty.

What Can Cause an Oil Tank To Leak?

  • Exposure of the oil storage tank to wide temperature swings, especially in cold and humid climates can increase in-tank condensation (water)  leading to corrosion.
  • The oil inside the tank corrodes the tank.   How is it possible that oil can corrode metal.   Bacteria forms in the tank from moisture (condensation), since we want clean air EPA has mandated that the sulfur content in fuel is lower.  An environmental such as a tank of oil with low sulfur is actually a conducive environment for bacteria.  So now you have bacteria thriving in the tank as part of their biological activity corrosive compounds are created from the bacteria that corrode the tank.  You got all that?
  • Above Ground oil tank Leaking
  • Exposure of the tank fill or vent pipes to rain, especially to roof runoff for tanks mounted under the eaves of a home and especially if the oil fill cap is not securely tightened after filling with oil.  You see the rain water soaks the soil around the tank which hastens corrosions.  Tanks under concrete and asphalt tend to last longer as they are shelter from rain.
  • External oil tank rust due to exposure to the weather. Many small tanks, 275 to 300 gallon tanks were used for unintended uses.  Meaning many of these size tanks, were never rated for outdoor use, but have been used for outdoor use and some even buried.   You can tell what use a tank is rated for by reading the UL label that is affixed to the top of the tank.  Manufacturers of newer oil storage tanks in this size range often have removed this "indoor use only" wording from the UL label.
  • The tank in the photo was a basement tank, but was buried.  The tank was not rated (designed) for burial.  It leaked as the tank was not thick enough for the harsh environment of a buried tank.
  • 290 gallon tank AST was buried
  • Improper oil tank installation.  Meaning the tank was not designed for the current use.  We have found indoor oil tanks that were moved outside and placed onto the underground in the soil surface below a deck, and then partially to half buried. What is this tank, an underground tank or an aboveground tank?  (The government definition of a UST is one where 10% or more of the tank is buried below ground.) These tanks were not rated for outdoor use at all and are at extra risk of leakage due to placement of the tank body directly in contact with the soil.
  • damaged in use AST
  • Improper oil storage tank supports, such as failure to keep the outdoor tank off of the ground, to install it at the proper pitch and direction of pitch, and to install it on level surface, unsecured legs of the tank can lead to the tank tipping over, ripping open an oil line, and obvious discharge of oil from the tank.   This is more common with out-of-service tanks.

Keep in mind that if have an oil tank you need removed, this will most likely be a he only time in your life you will ever have to deal with something like this.  Odds are against you making the best decision regarding removing the underground tank, which is why we have devised this handy tank removal reference guide.   The following information regarding tank removal are a cumulation of 20 years of tank removal experience and speaking to people who had their tank removed and their decision making regret.

Google oil tank leak and you will see some scary web pages. If you are selling a property with a tank and don't you think it's an issue, realize your buyers are reading these pages and they know an oil tank can be an issue.

 Here are important oil tank removal fact.

  1. Most oil tanks do not leak.
  2. Most oil tanks that leak do not require expensive remediation and can be addressed by testing.
  3. Every state allows a permissible amount of oil to remain in the ground.

Few if any tank removal firms will tell you these facts.

Tank removals while not cheap can cost between $1200.00 and $2,000.00 on average.  Remediation of leaking oil tanks can cost $10,000.00, $16,000.00, $40,000.00 dollars or more.  Do I have your attention?  Many firms will suck you in with a competitive price on tank removal and then whack you with a bill to remediate the leaking oil tank.   Many people call our office after their tank is removed and after they get an outrageous proposal to remediate.   These tank remediation quotes appear on the same day as tank removal or within a few days and are 90% of the time baseless money grabs.  

Google oil tank removal and you will see some slick web pages, not as scary by any means as the tank leak search. These pages have happy people, testimonials and some sales oriented content. You may be swayed by the nice web pages or even that the company is LOCAL.   Local has nothing to do with an oil tank removal, you probably have a few pizza shops close by and one is your favorite.  Proximity to your property is not like a pizza shop, good environmental companies are not known to be as popular as pizza shops.  Contract with these firms and if your tank has any remote evidence of leaking, you will regret your choice of contracting.  Here is why. 

I had no indication that my tank was leaking and the company I hired agreed.

Big, big trouble is brewing in this sentence.  I would hope that no one wishes ill will on anyone, but let us look at an oil tank leak as a possibility based on the following.

Oil tanks do not last forever and on average a tank lifespan is between 20 and 30 years.

Age of tank.   If your oil tank is the original oil tank for the house and it is older than 30 years, well it has outlasted the refrigerator, washer, dryer, roof, ect. It is most likely the oldest replaceable fixture in the dwelling that was NEVER REPLACED.   So can we agree there is a CHANCE the oil tank maybe leaking?  Just a chance.   If your answer is yes, well should a brief conversation occur about the oil tank leak scenario?  If yes, then the what if my oil tank leaks discussion should be written into your oil tank removal contract, so you know what steps will occur in the event of a leak.   Trust me the answer is yes and your proposal like so many we see will not have the language in there and you are setting yourself up for problems. 

 Soil samples.  You do not want them because soil sampling is not required by law, you do not want to test because you do not want to find a problem.  I mean who wants to go to the doctor, you know the doctor is going to find something wrong.  Soil sampling after a tank is removed is 100% important and not sampling is the biggest mistake you can make. 

Remember the google search for oil tank leak?   Well how are you going to certify the tank did not without testing?   Perhaps you think the township will inspect and certify the tank did not leak?  Wrong their job is a construction inspection, remember they are not licensed to remove an oil tank, the company you hired is licensed and they hold the burden to certify the work.

How do we certify that a tank did not leak?  

Not by looking at it, believe it or not.  No one knows your cholesterol level without blood work, there are marathon runners that have heart disease, healthy looking people get cancer, my point is looks can be deceiving you cannot look at an oil tank and be 100% certain the tank did or did not leak.   Please do not tell me you will be able to tell if the tank leaked because you are going to look for black oil in the ground, because everyone knows that is how you can tell, WRONG.   The tank is not the Beverly hillbillies, heating oil is not black its dyed red.  (Google it, heating oil is red, no lie).

Back to soil testing, hey if you were buying a house with an oil tank that was removed, wouldn't you want testing completed and a report certifying the tank did not leak?  If you don't care, leave this web page, go play words with friends, understanding the pitfalls of oil tank removal are not your topic of interest. 

Soil testing protects you from unscrupulous tank removal firms that would remove your tank, show you a hole in the tank after removal, show this hole to the construction official, report you to the state and give you a cost to remediate, which is many times more expensive than the tank removal and more profitable for the removal company.

 

Here is the short story of a property where a tank was removed, the tank was found to be leaking and got a quote 

1.Oil tank was removed.

2.Property owner want soil testing.

3. Tank removal company says soil testing is a waste of money.

4. Tank removal company has X-ray vision and can just tell that the tank leak is bad and you need remediation, why test?

5. Owner is told testing is expensive, $5,000.00, true story, owner was told why spend the money to test if you know it leaked?

6. Truth, testing of an oil tank, say a 275 to 550 gallon oil tank would cost under $250.00!  Think that money is worth spending?

7. Owner was given a quote to remediate a day after removal.  

At this step in the tank removal, the ownerr felt something did not add up.  Owner brought in another company to test the removed tank area.   Yes contamination was found, but it was with acceptable standards.  

Success tank removal depends on testing, if you test, you could save thousands in unnecessary oil tank remediation.

If you don't test the soil after a tank is removed, the removal company can quote you an expensive remediation, good for them, not for you.

Why are we posting oil tank removal problems, showing you how to be a better consumer of these services, well we remove tanks but we also help people who had their tank removed and we are repeating their stories for your education.   Unethical tank removal firms give all companies a bad name.   To be frank as well, we get a little tired of hearing the same story over and over again.

 Common compliants after a tank is removed?

My oil tank contract was based on the tank not leaking.  It leaked and I am getting billed alot more than the cost of the removal.

My tank had holes when it was removed and I have to remediate.

My leak was reported to the NJDEP AND NOW I HAVE A CASE NMBER.

The removal company said testing wasn't in my contract so they didn't test.

The removal company said testing was a waste of money and I have to remediate.

Environmental company gives a 10k quote to remediate, my house is under contract for sale and I have to clean up the leak or risk losing the buyer.

 

We have been involved with more projects than I care to count that fits those details. Sit down before I tell you what we find at these sites.

Close to 80% of the time, we find little to no oil in the ground or we find that oil levels are within acceptable levels, meaning no expensive remediation.

The other 20% of the time, well yes, remediation was necessary but sadly, not to the extent they were quoted.

Oil Tank Removal in New Jersey

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).
