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

Posted by david sulock on Jul 25, 2018 9:11:47 AM

 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.

 

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.

How long does an Oil Tank Last?

Posted by David C Sulock on Mar 6, 2018 4:01:00 AM

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.

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.

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 1 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 leading to corrosion
  • 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.  
  • 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.
  • Improper oil tank installation  of improper oil tank type.  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.
  • 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.

Successful Oil Tank Removal - Avoid Tank Problems

Posted by David C Sulock on Jun 6, 2017 9:57:36 AM

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.
