Fuel oil tanks are used to heat homes that are not connected to the mains gas system. Over time, debris, water, and other contaminants can accumulate in the tank, turning into sludge that collects at the bottom. This can cause corrosion and leaks, leading to costly environmental damage and health risks. As such, it is important to regularly inspect and clean fuel oil tanks. When upgrading to a new heating system, the old fuel oil tank must be properly disposed of, which can be a complex and costly process. Homeowners must ensure they comply with local regulations and engage qualified professionals to safely remove, recycle, or reuse the tank and its contents.

Removing oil from a fuel tank
If you are removing oil from a fuel tank, you will need a fuel transfer pump and drums suitable for heating oil. Fuel transfer pumps can be purchased online or from a local hire store. Most are portable and do not need an electric power supply, instead, they can be attached to a car or leisure battery to power the pump. Using a fuel transfer pump is relatively simple. One end has a filter to ensure no debris is transferred, and the other has a trigger to start the transfer. To transfer the oil, place the filter end into the oil tank until it reaches the bottom, then place the trigger end into a drum or new oil tank. Connect the alligator clips to your battery, red to positive and black to negative.
A good quality fuel transfer pump can move up to 40 litres of heating oil per minute. If you are transferring oil into drums, be careful as a 25-litre drum will fill up quickly. Be ready to depress the trigger and turn the pump off before moving the trigger to the next drum. Turn the pump back on and press the trigger to transfer the oil into the next drum. As the tank empties, the transfer of heating oil will slow. When the filter is not fully submerged in oil, stop the pump and elevate the far end of the tank so that the remaining oil runs down towards the filter. Let the heating oil settle for 5 minutes, allowing any dirt and debris to settle at the bottom before starting the pump to drain the remaining heating oil.
If you are removing a fuel oil tank, it is important to contact a professional firm that is qualified to do so. The cost of removing an aboveground storage tank varies depending on the degree of contamination and local clean-up standards, but it can be expensive. In New York State, the average cost of removing an aboveground storage tank is around $2,600. The EPA estimates that the removal of an underground storage tank will cost anywhere from $10,000 to over $1 million, with an average cost of $130,000.

Removing a fuel tank
Engage a Professional Firm
Firstly, it is imperative to engage a professional firm that specialises in fuel tank removal. Fuel oil is extremely toxic and flammable, so removal should be left to experts. Ensure that the firm is permitted to work in your area and carries pollution liability insurance. Contact your local fire department for recommendations on reputable and qualified companies.
Extract the Fuel Oil
Before removing the tank, the fuel oil must be extracted safely. A professional removal contractor will use a special explosion-proof pump to remove the oil. This oil can then be filtered and reused, ensuring that every valuable gallon is utilised efficiently.
Dispose of the Tank
Once the fuel oil is removed, the tank can be disposed of properly. This may involve cutting the tank into pieces for recycling or reusing the tank for another purpose. Any remaining sludge or residue should be removed and placed in sealed drums for specialised waste management.
Comply with Regulations
Depending on your location, there may be specific regulations governing the removal and disposal of fuel tanks. Some states require the registration of underground storage tanks, and homeowners must disclose their presence when selling a property. Aboveground storage tanks may also be subject to regulations, with some states requiring regular inspections by qualified professionals. Ensure you understand the local requirements to maintain compliance.
Address Environmental Concerns
Fuel tanks, especially underground ones, can pose significant environmental hazards if they leak. The longer underground storage tanks remain buried, the more likely they are to leak, causing serious ecological damage and incurring costly expenses. When removing the tank, ensure that any contaminated soil or materials are properly remediated and disposed of according to environmental standards.

Disposing of a fuel tank
Engage Professionals
Firstly, it is highly recommended to engage professionals for fuel tank disposal. This is because fuel oil is extremely toxic and flammable, posing significant risks if not handled correctly. Professionals will have the necessary expertise, equipment, and insurance to carry out the job safely and effectively.
Research Local Regulations
Before starting the disposal process, it is essential to research and understand the specific regulations governing fuel tank disposal in your area. These regulations may include permit requirements, disposal methods, and documentation. Contact your local fire department or relevant authorities to inquire about the necessary permits and procedures.
Extract and Reuse Oil
Before disposing of the tank, any remaining oil should be carefully extracted and stored in secure containers. This oil can be filtered and reused for heating or taken to a designated hazardous waste facility for proper disposal. It is important to ensure that all oil is removed from the tank to prevent environmental hazards and comply with disposal requirements.
Clean and Cut the Tank
The fuel tank must be thoroughly cleaned before disposal. This process may involve steam cleaning or other methods to ensure no oil residue is left behind. In some cases, cutting the tank into pieces may be necessary for easier transport and disposal. However, extreme caution must be exercised when cutting, as using tools like grinders or abrasive wheels on a tank that is not completely oil-free can be dangerous.
Dispose of the Tank
Once the tank is cleaned and cut, it can be disposed of at a licensed recycling facility or scrapyard. Some facilities may have specific requirements, such as accepting only cut-up tanks. Ensure you have the necessary documentation and permits to dispose of the tank, and be prepared to provide proof of proper disposal if required.
Additional Considerations
It is worth noting that the cost of fuel tank disposal can vary depending on factors such as the degree of contamination, local clean-up standards, and accessibility of the tank. Underground storage tanks may be more expensive to remove and typically require registration with local authorities. Regular inspections by qualified professionals are recommended to maintain safety and identify potential issues.

Regulations for fuel tank disposal
It is important to note that fuel tanks contain combustible materials, so they need to be thoroughly cleaned before disposal. This includes removing any residual fuel and properly disposing of the wash water. Failure to do so may result in hazardous waste and contamination of your property.
Some states, like Florida, have specific requirements for fuel tank disposal. For example, in Florida, you may need to obtain a permit before removing the fuel tank, and there may be guidelines on acceptable disposal methods. Non-adherence to these guidelines can lead to penalties.
Additionally, some states and municipalities require registering above-ground storage tanks and mandate regular inspections by qualified professionals to ensure they are safely sealed. However, for the most part, storage tanks with a capacity of less than 1,100 gallons are not regulated, and it is the homeowner's responsibility to ensure there is no leakage or corrosion. Regular inspections, at least once a year, are recommended to maintain safety and identify any potential issues.
