What is the recommended clearance around an underground tank to prevent soil compaction?

• A. At least 1 foot
• B. At least 2 feet
• C. At least 3 feet
• D. At least 5 feet

Answer: (C)

The recommended clearance around an underground tank to prevent soil compaction is at least 3 feet. This distance is crucial because it allows for proper soil structure and drainage, which helps avoid excess pressure on the tank walls and mitigates the risk of soil settling or becoming too compacted over time. Soil compaction can lead to shifting and can compromise the integrity of the tank, potentially causing leaks or other issues. Maintaining a clearance of 3 feet ensures that the tank is adequately supported by the surrounding soil while providing enough space for any necessary maintenance or inspections in the future. This standard helps to uphold safety and longevity for underground tanks, taking into account the natural movement and behavior of the soil around them.
