Do I need to remove that old oil tank in my crawlspace?

On occasion during our home inspections on Long Island, we see old, abandoned oil tanks in crawl spaces. We always recommend removal of an abandoned tank in the crawlspace because sooner or later it will rust out and start to leak residual oil and sludge. In fact, it may be oozing out of the tank already. If the crawlspace happens to have a dirt floor, long term leakage could lead to an environmental concern. In addition, it could cause a fuel oil odor.

Typically, crawlspace oil tanks need to be cut up before they can be removed, and properly discarded. This work should be done by an oil tank specialist.

Make sure that the old fill pipe and vent are removed from the side of the house to avoid an oil flood caused by an inadvertent mistake on the part of oil tank delivery technician with a wrong address. It happens, every once in a while, oil is pumped into the basement or crawlspace because they never removed the pipes after they removed the tank. Now you’ve got a real problem!

So, yes, it makes sense to remove an old tank in the crawlspace to avoid potential problems in the future. We hope this was helpful.

In-ground Oil Tanks

INGROUND OIL TANKS

An in-ground oil tank can obviously be an environmental concern. If the oil tank is leaking it will be your responsibility to remove ALL the contaminated soil regardless of how much soil must be removed. If the contaminated soil goes underneath the foundation of your home or your neighbor’s home, the process for removing the contaminated soil becomes much more complex because the foundation must be supported as the soil is removed. This is known as “under pinning”.  In addition, all of the soil is considered a contaminated material in must be disposed of properly. The implications of an oil leak in the ground are huge. Oil leaks can cost hundreds of thousands of dollars in remediation efforts.

Fortunately, for Long Island Home Inspection, the authorities have made it quite easy to have an oil tank abandoned in place. It simply requires contracting with a company that is licensed to deal with oil tanks and having them perform the abandonment. The abandonment includes removal of the oil in the tank, and then filling the tank with either sand, foam or concrete. Then, all of the pipes are removed and you receive paperwork evidencing that the tank was properly abandoned. Keep this paperwork on file for future proof that the work was done properly. It’s as simple as that. Typical abandonment costs range from $800-$1,500 depending on the size of the tank. At that point, you either install another oil tank or convert to gas. A new oil tank can be installed above ground or in the basement. You can even have an oil tank put back into the ground but it must be Fiberglas and is typically guaranteed for 30 years.
