Burying 250's and up is common and actually required in some applications and jurisdictions.

I put a 500 underground in 2005. New construction, no problem with the insurance besides the $. They whack you on the cape because of the wind/water potential, and like pops02 points out there are only a few insurers willing to write up houses on the cape. Got you by the short ones. I digress - they didn't have any problem with an underground gas tank. If it was oil you have a problem like Sandman says.

Man I never heard of that! I figured where the tanks were under pressure that it would be a problem being buried and especially when the tank begins to rust through?
