Contact local environmental agencies or waste management authorities to understand rules for old oil tank disposal. Some regions require permits or inspections before removal, while others have specific guidelines for handling tanks that previously held hazardous substances. Failing to comply can lead to fines, so aligning with local requirements is the first critical step.
Drain all remaining oil using a siphon or pump, and store the oil in approved containers for recycling or proper disposal—never dump oil into drains or soil. Then, clean the tank's interior to remove sludge, residue, or vapors. This step is vital because leftover oil or fumes can be flammable during removal, and residue may leach into the environment if the tank is not cleaned properly. Use non-toxic, oil-specific cleaners to avoid damaging the tank or creating additional waste.
Old tanks, especially underground ones, can be heavy and may have corrosion or structural damage that makes DIY removal risky. Professionals have the tools and expertise to lift or excavate the tank safely, avoiding leaks or damage to surrounding areas. They can also assess if the tank can be recycled—many steel or metal tanks are recyclable, reducing waste—but if the tank is too damaged, they will transport it to a licensed disposal facility.
- Proper certification for hazardous material handling
- Experience with oil tank removal specifically
- Valid insurance coverage for potential accidents
- Knowledge of local disposal regulations
- Appropriate equipment for safe removal
For underground tanks, check the surrounding soil for oil contamination after removal. If contamination is found, work with environmental experts to clean the soil using approved methods, such as bioremediation or soil replacement. This ensures the site is safe for future use and prevents long-term environmental harm. By following these steps, you can dispose of an old storage oil tank safely and responsibly.
