Fuel oil tanks in old homes
Fuel oil tanks were common in homes from the 1930s to the 1980s, with 32% of houses in the United States using oil heat by 1960. However, its use has declined to just 7% today, although it remains popular in the Northeast, where more than 30% of homes still burn oil.
Underground oil tanks pose an environmental hazard and are considered a risk for new homeowners due to the possibility of soil and groundwater contamination. Over time, tanks can corrode or be damaged, compromising their walls and allowing oil to leak out. This contamination can be costly to clean up, and it may not be covered by homeowners' insurance. As a result, many realtors advise clients to remove underground oil tanks before listing their properties, as most buyers will not want to take on the risk, and banks may not offer mortgages for such properties.
If you are buying or selling a home with an underground oil tank, it is essential to test for corrosion and soil contamination. A tank sweep with ground-penetrating radar (GPR) can help identify the presence of a tank, and further tests can determine if it is leaking or at risk of future leaks. Removal costs for underground tanks are around $2,500, while basement removal is cheaper at about $1,000.
If you are removing an oil tank, it is crucial to follow strict regulations governing the removal and disposal of the oil and tank. Make sure to hire a qualified company that carries pollution-liability insurance and is OSHA-trained and certified. The oil can be sucked out of the tank using a hose and an explosion-proof transfer pump, then filtered and reused for heating.

Removing old fuel from oil tanks
Prepare the Tank for Removal:
Firstly, it is essential to understand that removing old fuel from an oil tank is not a DIY project. Strict regulations govern how oil and the tank must be removed and disposed of to prevent accidental oil spills. Contact a local removal contractor or firm specialized in decommissioning and removing fuel oil tanks. Ensure they have the necessary permits, pollution-liability insurance, and OSHA certification.
Extract Reusable Fuel:
Before removing the tank, a professional will extract the reusable oil from the tank using a special explosion-proof pump. The uncontaminated fuel will be siphoned into a drum and can later be filtered and reused for heating.
Remove the Tank:
After the fuel is removed, the next step is to remove the tank itself. This may involve cutting the tank open to clean the inside walls and remove any sludge, a mixture of rust particles, water, oil contaminants, and bacteria. The sludge will be placed in special drums and taken to a waste management facility for industrial use. The tank's vent and fill pipes will also be severed and removed.
Dispose of the Tank and Waste:
The removal company will ensure that the tank and all its contents are properly disposed of, recycled, or reused according to state guidelines. In some cases, the tank may be cut up and recycled, while the oil may be filtered and reused. It is important to obtain a disposal ticket or proof that everything has been handled correctly.
Costs and Considerations:
The cost of removing an old oil tank can vary depending on several factors, including the complexity of the removal, the degree of contamination, and local clean-up standards. Costs can range from $250 to over $1 million, with an average cost of around $130,000 for underground storage tank removal. Regular inspections and maintenance of oil tanks are essential to identify any issues early on.
It is important to note that fuel oil is toxic and flammable, so it is crucial to prioritize safety and adhere to regulations throughout the removal process.

Old fuel oil tanks and the environment
Old fuel oil tanks can have a detrimental impact on the environment. Underground oil tanks were common from the 1930s to the 1980s, and many homes still use fuel oil stored in tanks. Over time, these tanks can corrode and leak, contaminating the surrounding soil and groundwater. This can have far-reaching consequences, impacting public health, wildlife, and agriculture. Leaking oil can render groundwater unusable for irrigation, affecting farmers and potentially harming ecosystems.
The process of removing old fuel oil tanks can also be challenging and risky. The tanks must be emptied, recycled, or reused according to strict guidelines, and improper removal can lead to accidental oil spills, causing further environmental damage. The cost of cleaning up such spills can be substantial. Homeowners are often advised to hire professional tank removal services to ensure compliance with regulations and minimize the risk of spills.
The conversion from fuel oil to alternative heating sources, such as natural gas, has gained popularity due to concerns over the environmental impact of oil. Natural gas is fed continuously into homes through underground pipes, eliminating the need for oil deliveries and reducing the risk of running out of fuel. Additionally, natural gas boilers are more energy-efficient, helping to reduce overall energy consumption.
The environmental impact of oil extends beyond fuel oil tanks. The exploration, production, and transportation of crude oil can also have negative consequences. Techniques like hydraulic fracturing ("fracking") use large amounts of water and potentially hazardous chemicals, which can affect water availability and contaminate aquatic habitats. Exploring for oil under the ocean floor may harm fish and marine mammals, and drilling often requires clearing vegetation, disturbing ecosystems.
To mitigate these environmental concerns, regulations and safety standards have been implemented. For example, the U.S. Department of Transportation and the Federal Railroad Administration established new standards for railroad tank cars to reduce the potential for oil spills from trains. Double-hull standards for oil tankers have also significantly reduced oil spills at sea. These measures aim to minimize the environmental impact of oil, both in its extraction and its storage and transportation.
