Whether you are buying or selling a house, it is important to know if the oil tank has or is leaking. If removal is not an option we recommend testing the oil tank and the soils around it.
One of the most common misconceptions about oil tank testing is that is done with pressure. In fact, the opposite is done. When a tester performs a tank test he puts your tank under 3 pounds of vacuum and places a microphone in your tank. The down side is there are many reasons a tank can FAIL a tank test, causing a spill number to be created.
Sometimes the 3 pounds isn't enough to pull air through holes in the bottom of leaky tanks and other times the tank may fail due to a piping issue. For more information http://barrier.com/failedtanktest.html
We advise our clients; buyers, sellers and home owners to replace the underground storage tank with an above ground heating oil tank. Especially when it is an older tank. At least you will have a new tank afterwards.
Another way is to test the soil around the tank. This is called a subsurface investigation or tank assessment. This investigation tests the soil and/or water around your oil tank. It allows you to know whether the soil/water around the tank has been impacted.
In the end, any single wall underground home heating oil tank should be replaced with an above ground oil tank. Even if the tank passes a tank test or subsurface analysis.

Information on Failed Oil Tank Tests in New York
Did you know failing a tank test creates a NYS Spill Number?
If you have failed an oil tank test we recommend replacing the oil tank with an above ground oil tank. This creates is the best value for the money you will spend.
When an oil tank fails a tank test, also know as pressure test but is actually a vacuum and acoustical test, the tester must notify the New York State Department of Environmental Conservation (NYSDEC). Once notified, the NYSDEC will assign your property a Spill Number. A Spill Number is like a case number used to reference your property and the actions taken. Once the Spill Number is assigned an investigation is required to find out if any soil or groundwater has been impacted and if further action is required.
This can involve excavating to the top of the tank and checking the fittings, connections and piping. It can also lead to removing the oil tank, impacted soil, taking samples and sending the NYS DEC documentation of the actions taken.
If the breach is in the vent or fill, the top of the tank needs to be exposed and the piping replaced then a retest must be preformed. If this passes the report needs to be sent to the NYSDEC.
If the breach is in the oil lines, the top of the tank needs to be exposed then the oil lines need to be exposed and replaced. Finally the tank needs to be retested.
If the breach is not found after replacing the vent, fill, oil lines and failing the second test the tank needs to be removed. After the tank is removed the pit needs to be inspected and sampled. If the samples come back with contamination a remediation must be done.
In the end any single wall underground home heating oil tank should be replaced with an above ground oil tank. Even if the tank passes a tank test or subsurface analysis. For more information visit www.barrier.com or email waynejr@barrier.com
