Underground oil tanks make homes less appealing to buyers and realtors

Underground oil tanks are a significant concern for both buyers and realtors. They pose several risks, including environmental hazards, costly removal processes, and the potential for oil contamination. These tanks were common in homes built before 1975, and their presence can significantly decrease a property's resale value.

Realtors often advise their clients to remove underground oil tanks before listing their homes for sale. This is because most buyers are reluctant to purchase properties with these tanks due to the associated risks and costs. Even if a buyer is willing to take on the liability, there may be challenges with mortgage approvals, as many banks are hesitant to offer financing for such properties.

The detection and removal of underground oil tanks can be expensive. Buyers typically expect the seller to bear these costs, which may deter potential purchasers. Additionally, there is a risk of oil contamination in the soil, which can lead to costly remediation expenses. The presence of these tanks can also increase homeowners' insurance costs, as leaks may not be covered by standard policies.

To make matters worse, many filled oil tanks have not been properly cleaned or documented. This means that even if a tank has been filled with sand or other inert materials, there may still be oil residue or leaks that can cause problems for the new homeowner. As a result, buyers are often leery of properties with underground oil tanks, and realtors may steer their clients away from such listings.

In conclusion, underground oil tanks can make homes less appealing to buyers and realtors due to the potential risks, costs, and complexities associated with their presence. To increase the marketability of a property with an underground oil tank, it is advisable to have the tank removed by a professional company and address any environmental concerns with the help of certified contractors.

Oil tanks should be removed before listing a home on the market

The presence of an underground oil tank can also lead to environmental contamination. Over time, these tanks can corrode and develop leaks, releasing fuel into the ground. This substance can then leach into groundwater and nearby bodies of water, causing lasting damage to the environment. The cleanup of this contamination can be expensive, and homeowner's insurance may not cover these costs.

In addition, there may be issues with the documentation of the tank's removal and the condition of the soil surrounding it. Proper documentation includes a narrative drafted by an environmental company indicating that the tank was cleaned of residual oil, soil samples were acquired, and the tank did not leak, as well as documentation that the tank was filled with an inert material. However, many previously completed tank abandonment projects lack this documentation.

Furthermore, there is a risk that the tank may still be leaking, even if it has been filled with sand or another inert material. Sand does not absorb oil, and if the tank was not properly cleaned before being filled with sand, oil and rainwater can mix with the sand, causing further contamination.

Therefore, it is advisable to have the oil tank removed before listing a home on the market to avoid any potential problems and assess any current damage. A quality and professional contractor should be hired to remove the oil tank and provide soil samples for analysis. This will help ensure that the tank and the surrounding soil are free of any contamination and that the removal complies with all relevant regulations and permits.

In summary, removing oil tanks before listing a home on the market is crucial to avoid potential complications, environmental contamination, documentation issues, and the risk of leaks. By addressing these concerns proactively, homeowners can increase the market value of their property and provide peace of mind to potential buyers.

Soil testing is required to check for contamination

Filling an underground fuel oil tank with sand is a common practice for homeowners who have converted to natural gas or above-ground storage tanks. While this method is acceptable according to construction codes, it is important to note that soil testing is required to check for contamination.

Soil contamination can occur through various means, including human activities that deposit hazardous materials, such as pesticides, heavy metals, and petroleum products. In the case of underground fuel oil tanks, there is a risk of oil leakage, which can contaminate the surrounding soil. To ensure that the soil is not contaminated, it is necessary to conduct soil testing before filling the tank with sand.

Proper soil testing involves taking soil samples from below the tank and submitting them to a laboratory for analysis. This analysis can determine the presence of any contaminants and their levels. It is important to work with a qualified professional, such as a soils engineer, to ensure accurate results and proper interpretation of the data.

In some cases, homeowners or contractors may not have conducted soil testing before filling an underground fuel oil tank with sand. If you are considering purchasing a property with such a tank, it is highly recommended to have a soil test done to assess any potential contamination. This will help identify any issues and allow you to make an informed decision about the property.

Additionally, if you are selling a property with an underground fuel oil tank, it is advisable to have the tank removed before listing the home. Homes with underground oil tanks can be challenging to sell due to the potential complications and concerns about soil contamination. Removing the tank and conducting soil testing can help alleviate these concerns and make your property more appealing to potential buyers.

Tanks are filled with sand, stone or foam as per construction code

Filling an underground fuel oil tank with sand, stone, or foam is a common practice for homeowners who have switched to natural gas or installed an above-ground storage tank (AST). This practice is permitted by construction codes, which allow for oil tanks to be closed in place when removing them would cause greater disturbance. However, it is important to note that proper procedures must be followed to ensure safety and compliance with regulations.

When filling an underground fuel oil tank, it is crucial to engage a qualified contractor to perform the work. The process typically involves excavating a portion of the tank, removing the oil, and then filling the void with an inert material such as sand, stone, concrete, or foam. This inert material is safe and will not cause damage to the container or the surrounding soil.

One critical aspect often overlooked is soil sampling and testing. Before filling the tank, it is essential to test the surrounding soil to ensure no contamination has occurred due to leaks. Proper documentation, including a narrative from an environmental company, soil samples, and confirmation that the tank was filled with an inert material, is necessary to demonstrate compliance with construction codes. Without this documentation, there may be legal and financial consequences if issues arise in the future.

Additionally, it is important to address any remaining oil or toxic gases in the tank before filling it with sand, stone, or foam. These substances must be safely removed to prevent them from mixing with the inert material and causing further contamination. Engaging a reputable company specializing in oil tank removal and cleaning, such as Simple Tank Services or All American Environmental, is crucial to ensure that the work is done correctly and in compliance with state mandates.

In conclusion, while it is permissible to fill underground fuel oil tanks with sand, stone, or foam as per construction codes, proper procedures must be followed. Homeowners should engage qualified contractors, ensure soil testing and documentation, and address any remaining oil or toxic gases to maintain safety and compliance with regulations. By taking these steps, homeowners can avoid potential issues when selling their property and ensure the protection of their families and the environment.

Tanks should be cleaned before filling with sand

Filling an underground fuel oil tank with sand is a common practice when a homeowner switches to natural gas or an above-ground storage tank. This practice is allowed by construction codes, especially when the tank is buried beneath obstructions like patios, decks, or driveways, and removing it would cause more disturbance than filling it in place.

However, it is essential to clean the tank before filling it with sand to prevent future problems. Proper cleaning and abandonment of an oil tank involve several critical steps. Firstly, the tank must be located, often with the help of metal detectors. Once the tank is found, professionals will inspect the surrounding area for any signs of oil stains, broken pipes, or the smell of gas.

The next step is to remove the tank and extract any remaining oil or toxic gases using specialised tools and vacuuming techniques. This process ensures that these hazardous materials do not contaminate the soil or pose health risks to residents. After the tank is removed, it is cut open, and any residual oil is cleaned out. This step is crucial as sand does not absorb oil, and if oil remains in the tank, it can mix with rainwater and spread into the sand, potentially causing future issues.

Once the tank is cleaned and free of any oil residue, holes can be cut through the bottom to access soil samples for laboratory analysis. This step confirms whether the tank was leaking and causing soil contamination. Only after this thorough cleaning and inspection process should the tank be filled with clean sand and left in place, or the space where the tank was located be filled with an inert material such as sand, concrete, or foam.

It is worth noting that some states mandate the removal, inspection, and replacement of underground storage tanks (USTs) and that proper documentation of the cleaning process is essential. Tanks should be cleaned and abandoned by qualified professionals who follow authorised standards and procedures to ensure safety and compliance with local regulations.
