As a homeowner, you may have an underground heating oil tank on your property that you no longer use. Whether you have switched to a different heating source or no longer need a large tank, it’s important to consider the safety risks of keeping an old tank on your property.

Reasons for Heating Oil Tank Removal Seattle

Older underground heating oil tanks pose significant safety risks to homeowners and their properties. Over time, the tanks can rust, corrode, develop cracks, and leak oil into the surrounding soil and groundwater. This contamination can lead to environmental damage, health hazards, and costly cleanup expenses. Here are some of the reasons why you should consider removing an old oil tank from your property:

1. Environmental protection: Leaking heating oil tanks can contaminate the soil and groundwater, leading to environmental damage, and health risks. In addition, the presence of an old tank on your property can potentially lower its market value.

2. Safety concerns: Underground tanks are prone to corrosion, which can cause them to leak, rupture or collapse. Ruptured tanks can cause fires, explosions, and other hazards. Children and pets can also be at risk of falling into uncovered tanks and injuring themselves.

3. Cost savings: Removing an old tank before it becomes a liability can help you avoid costly emergency cleanups and repairs. In addition, the removal of a tank can free up valuable space on your property for other uses.

Steps in the Heating Oil Tank Removal Process

Removing an underground heating oil tank involves a complex and highly regulated process. Proper planning and execution are essential to ensure that the removal is done safely and legally. Here are the steps involved in the process:

1. Tank inspection: A qualified technician will inspect the tank to determine its condition and location. If there is evidence of a leak or other damage, the technician will advise you on the safest course of action. If the tank is still in good condition, it can be emptied and removed.

2. Permits and approvals: You will need to obtain permits from your local authorities to begin the removal process. The technician can assist you in obtaining the necessary permits and approvals.

3. Tank excavation and removal: The technician will excavate the soil around the tank to expose it for removal. Once the tank is exposed, it will be cut into smaller pieces for removal. The soil around the tank will also be checked for any signs of contamination.

4. Soil testing and cleanup: After the tank is removed, the soil around it will be tested to check for any signs of contamination. If contamination is found, the soil will be removed and disposed of properly. The area will then be backfilled and compacted.

5. Tank disposal: The removed tank will be transported to a licensed facility for disposal or recycling. This is typically the last step in the process.
