I never understood the move of gas tanks from above ground to underground. The few stations left with above ground tanks were forced to bury them ages ago.
To me, you can easily detect leaks if above ground and correct. The local Gov can even hire someone to check above ground tanks. Seems oil companies did the move to avoid inspections.
