Abstract
A fueling environment reduces the likelihood of fuel spilling into the environment by positioning an underground storage tank directly beneath one or more fuel dispensers. The amount of piping thereby exposed to the environment is reduced, reducing the locations at which a leak may occur. The underground storage tank is partitioned into two or more chambers to hold different fuel grades such that a single tank may provide at least two fuel grades to the dispensers above the tank.
