When buying a house you inherit the improvements, the land, and the fixtures. An oil tank would be classified as a fixture as it is connected to the house as a fuel source. Generally speaking, an oil tank would be thought of as something typically transferred during the sale.  The tanks in the photo below are newer, about 13 years old, and are in an 80-year-old house, the layperson's opinion would be great new oil tanks, right? Well, the older, wiser bull would ask -  what happened with the prior oil tank?

The answer would be the prior oil tank is in the ground or rather underground, and the in-use underground oil tank was replaced because the water was entering the oil tank the oil tank was not removed because it cost money and the new oil tanks were an unexpected expense. Trust us the buyer is going to want the buried tank removed.

To finish the story above, one of the oil tanks did leak, about $14,000 to clean up, so not that bad.

Oil tanks are a great exception when it comes to real estate.   Oil tanks are a known liability, a Recognized Environmental Condition (REC), or an Area of Concern (AOC). Oil tanks age and wear and when the failure occurs,  oil leaks, which causes soil contamination, which under current laws is the responsibility of the owner to repair and remediate.  Now, buyers are known to sue sellers after the sale occurs if they discover the oil tank leaked and buyers believe owners did not disclose this key defect. 

Can you sell a house with an oil tank that is in use or decommissioned or abandoned?  

Sellers can indeed legally sell the home, but in the rare times this does occur there is liability generated for both buyer and seller.   To buy a property with a tank is to assume the liability associated with the tank, which some buyers assume is no liability.

Why would a seller want to sell a property with an oil tank?

First to remove and replace an oil tank, budget $2,000 for removal and $3,000 or more to install a new oil tank. Converting to natural gas, budget $10,000. The first reason to sell with an oil tank is seller saves money and why would a seller want to upgrade a house they are selling? But that isn’t even the real reason sellers sell with an oil tank, it's because the remediation of an oil tank can cost $30,000 or more, or less, but the cost to remediate is more than most people can budget, so it’s an expense people avoid.

 So who has liability when selling a house with an oil tank?

Both buyer and seller have liability. For a seller, when the transfer occurs, no doubt the buyer is not anticipating a $50,000 cleanup and when that occurs, lawsuits occur as the buyer suspects the seller knew about the oil tank and lied. Sellers who sell tanks are viewed as used car salespeople. We have seen every sort of lawsuit from Estates to retired people to young couples selling to buy a larger home, in every scenario the buyer finds contamination that they believe the seller knew about. In most cases the buyer wins and the seller pays.

How does a buyer have liability for buying a property with an oil tank?

Buyer beware, break it you buy it, possession is 9/10^th of the law. Whatever the term, if you own the property, you own the problem. Sure, you can sue the seller as in our example above, but if it is say an Estate and the estate dissolves and the money is gone, good luck.

What if you have an abandoned oil tank and disclose it to the buyer?

Buyers buy homes where the seller discloses they had an oil tank filled in place tank, after they buy the property they realize that an abandoned oil tank doesn’t mean no leaks. The saying goes as long as it was abandoned properly, that oil tank does not present any legal issues. The real question isn’t whether a seller can do it, it’s whether a seller should or to put it in simple terms are you 100% the abandoned oil tank does not represent an issue?

Case in point, property being sold, owners did not disclose an oil tank.  The buyer does an oil tank weep and finds an oil tank.  Sellers dig up information on the oil tank, even though two days earlier they did not know the underground oil tank.   Curren Environmental is requested to review the paperwork.  It included an invoice, a copy of the permit (to fill the oil tank in place), a copy of the oil manifest, a hand-drawn map of the property and a one-page letter which I snipped below. 

Makes No Warranty or Certifications to Soil, Groundwater, or Environmental Conditions.

So did the tank leak?  I don't know, but the company that did the work is not saying it did or didn't. per the statement above. 

The next step is to the oil tank gets removed and tested, because the paperwork is insufficient in today's environment, but to be fair this wasn't sufficient in 2005 either, but the people who owned the house did not want to find a problem so they hired a company who would not test the soils.  Of course, flashforward to today and they are paying again to get the tank decommissioned so they can sell the property.

What do you have that says the oil tank did not leak? 9 times out of 10 it’s the wrong document, like my example above. A thousand other set of documents that is insufficient to certify the oil tank as nonleaking. 

Buyers and sellers need to be on the same page with oil tanks.

Did you look for contamination when the oil tank was abandoned?   Like when a dentist looks for cavities, when you abandon an oil tank there are steps you take to certify the tank did not leak, and also testing, like an x-ray.

What if you remove the oil tank instead of filling it in place? Would we find contamination?  

We often find contamination when removing abandoned oil tanks. Yes, you read that right, we find some evidence of contamination, of past soil contamination (maybe a previous tank buried in the same area as an abandoned oil tank, sometimes we find a 2^nd oil tank. In all these situations we find contamination that wasn’t picked up before, and now it's reportable to the state, and the owner has to clean it up. How do you know if you have proper documentation certifying a tank did not leak?

Every year we peer review thousands of reports, lab data, and documents about prior environmental work, to see if our clients are covered. Often the data is lacking or there is an issue that people gloss over.  In most all cases, we have to recommend the removal of the tank, which is reverse engineering the prior work.

Is it better to remove or abandon an oil tank?

Removal is always better because the tank is gone, there should be no issue if it leaked because you can see the tank out of the ground and it’s easy to collect soil samples from the ground after the tank is removed.

Tanks destroy curb appeal so if selling a house with an oil tank, no one is going to say hey that’s a benefit. The number of buyers is smaller than a property without an oil tank. A house that has an abandoned underground oil tank will stop most buyers in their tracks because the buyer doesn’t want to inherit some problem in the future.

We have had plenty of clients (who eventually hire us to remove the oil tank) selling with a properly abandoned oil tank, properly abandoned in the ground. All permits were obtained, but the deal repeatedly falls apart. Why?  Because the buyer goes into attorney review, and they talk to their attorney and decide they won’t proceed out of attorney review unless the seller agrees to remove and test the oil tank.

Now many developers and house flippers will buy a house with an oil tank, but you hope they disclose the tank to the next buyer, otherwise, lawsuits occur, and the original seller whom the flipper bought the house from gets sued. Why sue?   Because an oil tank is found and the buyer demands removal, then contamination is found and you, as the original seller, obviously knew about the contamination.

Let’s say you even find someone who wants to buy the house with the oil tank, well the mortgage company may have a thing or two to say. Most lenders are hesitant to make a loan on a property that has an abandoned underground oil tank, even if you have permits. Sometimes for certain loans, the oil tank makes the lender pull the load or the lender wants the tank removed to provide a mortgage.

These are some of the reasons why an oil tank should be properly removed and documented.   yo less likely to get sued and more interested buyers translate to a higher purchase price and of course less headaches.

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.

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?

The saying we get better with age, well that relates to a foundation of knowledge based on years of experience.   At Curren Environmental those that know teach, those that know, know from decades of experience thousands of sites.   We do peer reviews of the work of other environmental companies every day, thousands of reviews a year.  These reviews are both paper reviews (in office) as well as on site over seeing work for clients protection.  Needless to say we see the good and the bad.  The bad is also not always the cheapest price.  Bad projects have a common thread of promising things that they cannot deliver on or to be put frankly telling the client what they want to hear, even though this may be the opposite of what other firms are saying.  Key topics, don't worry about a leak, we can manage the leak if one is found, lastly we can remediate for a lump sum and we do not need any testing data (these firms have x-ray vision.

Recently I had to oversee the removal of a residential oil tank.  The tank was actually found via a GPR tank sweep by Curren. The  owner had no knowledge that a UST was present Tank Sweeps with GPR.    Owner got a really inexpensive cost to remove, so client (buyer) wanted the removal to be overseen.   Now I am not saying cheap isn’t good, everyone wants a bargain, you don't want to pay full price, but you also get what you pay for.  Cheapest is rarely best, its the cheapest.

The photo below shows one of the onsite projects reviewed. I knew that the person wearing gym shorts at 9 am  and no shirt  meant the day was going to be interesting.  Let’s start by saying, gym shorts and a tank top are not proper work attire.  It’s was a hot day so the gym short person took the tank top off, at was maybe 9:10 am.  Things didn’t get better from there.

Yes that is a person inside the tank with no PPE (personnel protective equipment, respirator etc.), completely not according to regulations.  

Although the company had lettered vehicles they spelled remediation wrong.  If you say your do something  you should be able to spell it.  

So the tank gets excavated just enough to clean it.  Took them 2 hours to remove the tank after cleaning, because the tank was 80% buried. They couldn't see the logic in uncovering the tank to the 50% mark so the earth wouldn't hold it in place.  Over the course of two hours, they damage the driveway, killed mature shrubs and after removal hit a sewer line that would have been avoided had they had gone into the basement to evaluate for utilities.  Inspecting a basement to see where underwound utilities enter is excavation 101, utilities are not marked accurately 100% of the time, property owners may not know on where what utility is located and lastly not all utilities get marked.  In any event the damage could have been avoided.

Now the good part, tank is removed and it requires two inspections.  No one knew of or when that would occur.  To be brief they had no inspection, took no soil samples (sampling is the only way you can 100% verify the tank did not leak) and backfilled the hole.

How do you avoid tank removal mistakes?

To be clear removing a tank is not building the international space station, but there are a slew of regulations and protocols you must follow API, OSHA, NIOSH.  You can check reviews on line for sure, but here are some tips that can find out the good from the bad.

1. Was the person you spoke with more car salesperson than environmental consultant?  You don't want to be sold into making a decision.
2. Did the company walk you though the steps they will follow?  This is an easy one and even the bad companies do it.  
3. Did they  put their steps in writing?  Again easy.  There should be a report stated in writing you will receive after removal, its super important.
4. Did they discuss the possibility of a leak?   What about if levels of oil are above standard?   What are the standards?  What amount of oil is permissible?  Look every tank could leak so you need to know the dark side of a tank removal that leaks, this needs to be discussed and put in writing.
5. Is their email a Gmail or yahoo email.  It might not sound like much but if a company doesn't have a hosted web site with hosted email with their domain, well you maybe buying into a Chuck in a truck.

It's tough to compare environmental services to other industries, but our office get a large share of property owners gripping about how the hired the wrong company.  To be fair most people will never have to remove two tanks in their lifetime or complete two mold projects, so you are doing something once and likely won't do a good job at it.

INTRODUCTION:

Our office gets a constant influx of calls from property owners who had an underground oil tank removed and ended up with issues from the company removing the tank (not Curren Environmental).  Tank issues include spills during the tank removal, permit issues or lack of obtaining permits,  no report included in the price and worst of all over the top expensive remediations that were not warranted. 

What you need to know before you remove your tank:

1. Licensed Company. Did you know that an unlicensed company could remove your oil tank?  It is true, but it is always better to hire a firm that is licensed for Closure (removal) and Testing (Subsurface).  Some companies have only one of the two required certifications.  If you hire the firm that can only remove and not test, you will have issues if remediation is needed, as they will have to subcontract services.  Hiring a licensed firm ensures that you are dealing with a firm that is capable of performing the tank removal through to completion.

2. Permits. Every tank removal requires a permit from the local construction office.   Each permit has a fee, while you may not know the exact cost of the fee - you need to be made aware of the fee.  The company who removes the tank (assuming you hired a licensed and insured firm) should always apply for the permit themselves. If a property owner applies for the permit, they are taking on the responsibility of ensuring everything is performed to code.  Property owners are neither licensed nor insured and do not have the knowledge on tank issues to assume that liability.

3. Tank removal costs. On average, removing an oil tank can cost between $1,200.00 and $2,000.00.  What makes a tank removal more costly is the work involved. Larger tanks cost more.  Tanks that are harder to access such as under decks or beneath asphalt/concrete can cost more.  That said, you get what you pay for has never been more true, choosing the lowest price can cause you to sacrifice quality.  Many firms lure people in with a low cost for removal knowing that a remediation of a tank leak can be between $5,000.00 to $15,000.00 (on average).  Ensuring they get to remove the tank means they have a better chance at recouping monies by remediating the tank leak.  Sometimes selling remediation services when they are not necessary.

4. Did my oil tank leak? This is the Number One question Curren Environmental is asked.   Tank removal companies can be very vague in explaining how they know your tank leaked.  To understand how to know 100% is to know the difference between qualitative and quantitative.                   

   1. Qualitative data is the description of data in a language rather than in numbers. This method does not measure the characteristics but describes them. Meaning, the tank removal companies sees a hole in the tank or smells the soil and it smells like oil or not, so the company says the tank leaked and you have to remediate it.  To put it more plainly in lieu of having your cholesterol tested the doctor guesses by looking at you.  

   2. Quantitative data is data that can be numerically counted it deals with measurements like height, length, volume, area, humidity, temperature, etc. Quantitative data would be testing of the soil after a tank is removed so you know 100% what the concentration of oil is in the soil.   Again, it can be compared to having your cholesterol level tested by getting blood work done.   Bottom line if you don’t test the soil, you don’t know if you need to remediate or not.

5. Assume your tank is not leaking. This is the backbone of most every tank removal contract Curren Environmental reviews. To be fair, it is an assumption and possible, but there is always a chance that the tank is leaking, even if it is a 1% chance, don’t you think that the tank contract should include a line item discussing what would happen if indeed the tank did leak.

6. No soil sampling listed in the tank removal contract. If your contract has no reference for soil sampling, be concerned, because when the tank is removed you will be told that they just know you have to remediate.

7. NJDEP reporting and obtaining a Case Number. Did you know that if the removal company sees a hole in the tank after the tank was removed they must call the NJDEP and get the property placed on the Known Contaminated Site List?

8. What level of oil requires remediation? If you have a tank leak, only testing of the soil will determine if remediation is required.  Your tank contract should include what the testing standards are, meaning how much oil is permissible in the ground.  Did you know that anything above 5,100 ppm for EPH demands remediation in New Jersey?  Did you know anything below 1,000 ppm for EPH is fine?  Did you know that if you are between 1,000 ppm and 5,100 ppm EPH you might not have to remediate (further testing is necessary)?

9. If the oil Tank Leaked now what? What if your tank leaked – what does the company do now? The company you contracted with should delineate, which means obtain soil samples to determine the size (area) of the leak. Not just guess the size so that they can make more money off the remediation.  In short, oil will spread out when it leaks from a tank, you need to obtain soil samples BOTH in and around the tank location to create a 3D model of the plume of contamination.  The company calculates the area length, height and width to determine how much soil is necessary to be removed.  If you do not follow this step you are more or less guessing.

10. Do you due diligence. Get more than one quote. Make sure the company has been in business for a long time and that they do not work from their home address or a PO Box.  Everything must be in writing.

Why my filled in place tank has to be removed?

(aka Closed in place tank has to be removed to sell a property)

Every tank needs a report with testing to say the tank did not leak. Tanks abandoned in place avoid having testing performed which negates finding out if the tank did or did not leak.

Case in point, the above photo is a tank that was filled with foam.  You will notice that there are no access holes cut into the tank that would have allowed tank entry.  Yes you can see the large horizontal access hole Curren cut into the tank, but  no such hole was there before, which means the tank was never cleaned of residual oil.  See the oil in the tank and on the foam? You can see that to clean a tank you need elbow grease to go inside the tank, any oil left in a tank can leak in the future, hence why closed in place are removed.

Remember when people thought smoking was healthy?   There was a time when people and the tobacco industry didn’t openly speak of cigarettes as being unhealthy or addictive. This correlates to tanks that were previously filled in place without a “non-leaking certification”.   Few people want to find a problem, meaning their tank leaked, since problems have to be solved and that can cost money.   Oil tanks rust from the inside and out, and the cleanup of these leaks can cost thousands if not tens of thousands of dollars.

This tank was filled with sand, to absorb the oil in the tank, rain water filled the tank pushing the oil up and out into the soils.  $29,000 later the tank was removed and the soil remediated.

Many property owners either being naïve or savvy had their buried tanks filled in place years ago.  Believing or hoping that if they hired a company to fill their tank (not a DIY project) and getting a local permit in conjunction with township/municipal inspection the tank would never be an issue. Fast forward to today, same property is being sold and its owned by either the same people who filled the tank in place or a subsequent homeowner (who typically naively bought the property not understanding the tank liability) and now the buyer wants the tank removed and tested.

These are all reasons why today's buyers want oil tanks removed and tested, to prevent the tank from being an issue in the future.

Statements from property owners calling our office about their tank over the past 25 years.

1. I don’t want to remove the tank and find a problem, its legal to fill it in place, I want to do that.
2. Why do I want to test the tank and find a problem?
3. I want the tank filled in place, I don’t want testing.
4. My tank was filled in place but they put a camera into the tank before filling it in place.  (Absurd, but a few people a year say this)
5. My tank was filled in place and tested. (Unfortunately I can find the paperwork for filling the tank I just cant find the testing data.  (Because it was never tested)
6. My tank was tested before filling in place, but a different company did the testing and I can’t find the eating data.  (No one pays two companies to do something one company can do, unsurprisingly these people cant find anything regarding testing, contract, invoice cancelled check.  We call this unicorn paperwork, only the pure of heart can see it)
7. Removing the tank will disturb my prized lawn, bush, special tree, sprinkler line, flower bed, etc.   They never say it was a bad idea beautify the area above the oil tank.

A little history, in the 1990’s Federal regulations were established regarding commercial tanks (gas, diesel, kerosene, aviation fuel) and there were clauses where a commercial tank could not economically be removed that the tank could be filled in place, AFTER holes were created in the bottom of the tank allowing soil sampling for leaks to be obtained.  

These regulations created a tank removal/closure industry and established standards for tank removal and closure in place, these standards said evaluate for leaks, do testing, document (draft a report of the work), report leaks to appropriate government environmental agencies.   So companies doing  tank closure had a Standard Operating Procedure (SOP).

These photos show coupons (holes) cut into bottom of tank for soil sampling.

Now these testing regulations didn’t apply to residential oil tanks, but there was an awareness that if a leak was discovered it was reportable and cleanup maybe necessary.  So property owners circumvented the proper course of action and instead of removing a tank, and potentially finding holes in the tank or smelling oil impacted soil, they chose the route of tank abandonment in place. While I can comment on every company doing tank work, but I am sure many recommended sampling due to future real estate transactions, but in the end, the companies get paid for doing tank work with or without sampling so you have thousands of tanks that were filled in place without testing that now have to be dealt with in a real estate transactions.  

We can personally  attest that Curren has always suggested soil sampling for tank removal or closure in place, some people deferred this testing.  About 17 years ago we made it policy, Curren won’t work on your tank if you don’t complete sampling.   We took this stance so property owners didn’t get stuck in a future sale and so people didn’t stick another person with a leaking tank. Unfortunately this was not followed by other companies.

Some 40% of tanks we have removed were tanks previously filled in place, so believe me if you have a property with a tank that was filled in place without testing, you will get it removed if you want to sell the property. 

No you can't climb inside a tank when filling it in place and see pin holes.  Ever get a flat tire?   Did you see the hole?   See the photo below?  This tank was removed, do you see any holes in the tank?

Well there were a few holes that were apparent after the dirt was scrapped off the tank.  If this tank was filled in place and remained in the ground, there holes would not have been apparent if the tank was not removed.

Many people like to present the local permit obtained for abandoning the tank.    People somehow think the approval from the town means the tank didn't leak.  Please note that no your local permit which the town approved for filling the tank in place doesn’t certify the tank didn’t leak!  It certifies you filled a tank in place with or without testing (which while legal, makes it harder to sell, ahem near impossible to sell)  mortgage companies, insurance companies and attorneys for buyers will have a hand in preventing the sale with an inground tanks.  Too much liability, unknown cleanup expense is what causes the hesitation.  No one knows if the potential tank cleanup is $10,000.00 or $120,000.00?

If you own a house with an abandoned untested oil tank, expect to either have the tank removed, or the prior work to be reverse engineered, meaning all the material in the tank removed, holes cut in bottom of tank and soil ampler obtained, then the tank back filled again.  We just did this for a tank filled with foam under an addition, so yes it happens.   Buyers will want the know if the tank leaked, trust me if you were buying a property with an abandoned tank you would want to know the same thing. 

Have a tank question?  Call the experts

If an oil tank has been removed and showed no visible signs of leaking, should soil samples still be taken? An oil tank was removed and showed no visible signs of leaking, the tank removal contractor did a pressure test and passed. As the buyer of the property, I am concerned that the tank area has not been tested.

To test or not to test an oil tank at time of removal? We get that question almost daily from both owners of tanks and purchasers of a property where a tank will be or was removed. Should you test an oil tank?

Does your dentist test your teeth via x-ray to look for problems? Does a doctor perform testing on patients? Can you determine cholesterol from just the physical appearance of a patient? My point being throughout life you have professionals performing testing to evaluate your health, testing a removed oil tank is the same principal.

The most important question about an oil tank is if it leaked. Owners of tank don’t want to test because they don’t want to find a problem. Buyers want oil tank testing performed because they don’t want to buy a property where an oil tank leaked.

The cost for testing most tanks at time of removal is a couple hundred dollars. Not a budget breaker for sure but finding even a small leak can cost thousands of dollars to address and the party responsible for cleaning up any tank leak is the property owner. So, buying a property with a tank leak (even if the buyer didn’t know if the tank leaked at time of purchase) is the responsibility of the property owner.


Common scenario, buyer want to purchase a home that had prior oil heat. The oil tank was removed previously (tank removed years ago). Sometime the tank was removed by the current property owner, sometime the tank was removed by a previously owner and the current owner was not aware of the liability from oil tanks and didn’t question the lack of testing. Buyer is concerned about buying a home where a tank was removed. So, in addition to performing a home inspection, the buyer wants soil testing completed from the removed oil tank grave. Post removal testing involves drilling and obtaining soil samples from the former tank location. Do we find some level of oil when we test removed tank location, yes. Do we find remediation is required from this testing, sometimes yes. Is the owner shocked when wee find contamination from removed tank areas? Sometimes owners are surprised as they bought the home prior to removal and didn’t view the oil tank as a liability. But there are definitely times where the owner has a hint that oil would be found and was hoping no one would look.

Testing removed tank locations is not as easy as you would expect. As time passes the restored ground returns to normal and little evidence of the tank grave is visible. Owners have selective memory of where the tank was and often point to absurd locations where the tank was removed. This requires sleuthing on our part and performing rows of soil boring to attempt to find the proverbial oil tank in the haystack. Any detection of oil found from a tank area is reported to the state as a spill clearly occurred.

Know before you buy a property that had oil heating. Testing is always advised by tank removal companies (The good ones at least). If testing was not performed, you have to ask, why? Buy a home with an oil tank leak and you just purchased an oil tank cleanup.

Questions that are quite often asked “Do I have a good underground oil tank or a bad one?”, or “What is the difference between a good or bad underground oil tank?”. Answering questions regarding underground oil tanks is an easy one, if your tank has been under ground since tanks started being buried (late 1940’s to early 1950’s), then there is no good or bad tank – you need to remove that oil tank. The tank has exceeded any functional and reasonable life expectancy.

In situations when the underground oil tank is still in use and older , the oil tank should be removed and replaced with an aboveground oil tank. Ask yourself a simple question, “Would you buy the house with an oil tank that old in the ground?”.

 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.

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.

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 2^nd 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.

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?

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.
