Abstract
A tank collar has an adjustable mounting surface for a containment sump, such that the containment sump may be adjusted on the tank collar to be substantially plumb, even if the tank collar itself is not plumb. In particular, the containment sump wall is angularly adjustable with respect to the tank collar, which is fixed to an underground storage tank (UST). This angular adjustability facilitates a method of installation in which imperfect angular orientation of the tank collar and UST may be compensated for by angular adjustment of the containment sump wall. During and after such angular adjustment, a consistent seal between the containment sump wall and the tank collar is maintained, such as in the form of a continuous line of contact around the circumference of the interface between the tank collar and the containment sump wall.
