1. A method of fabricating an above ground storage tank for holding a combustible material and for supporting equipment thereon, comprising:providing an inner tank for containment of a combustible material, said inner tank having a bottom wall, opposed side walls, opposed end walls, and a top wall, with a plurality of inner tank bottom wall stiffening members spaced along the bottom wall extending substantially completely across the bottom wall, and a plurality of inner tank top wall stiffening members spaced along the top wall extending substantially completely across the top wall; providing an outer tank metallic bottom wall having spaced support means on an upper surface thereof, with opposed vertically upwardly extending metallic side walls and metallic end walls, said side walls and end walls welded to the bottom wall about the periphery thereof and to each other to form a cavity; positioning said inner tank in said cavity and on said support means so as to provide an insulating gap between said inner tank and the bottom wall, side walls, and end walls of said outer tank with an insulating gap also provided between the top wall of said inner tank and a plane formed across the upper edges of the side walls and end walls of the outer tank; filling the insulating gap between the inner tank and the bottom wall, side walls, and end walls of said outer tank with an insulating material; filling the insulating gap between the top wall of said inner tank and the plane formed across the upper edges of the side walls and end walls of the outer tank with a hardenable insulating material; and hardening the insulating material.
