The only time I previously recall hearing something about above ground tanks was with Costco and their then "Clean Power" system where the fuel additive was stored onsite. But back then some industry presentation states that some of these tanks were above ground.
I don't think I've ever seen above ground tanks. As a kid I used "kid logic" and deduced that the fuel dispensed was stored in the part of the pump I could see. So when I saw one station with these really slim bases, I was wondering how they didn't run out of fuel quickly.
But yeah - apparently some have gone to above ground tanks. I could see how it could be much easier than dealing with digging up the old tanks when they need to be replaced. But they have to have their downsides other than just appearance.
