ABSTRACT:
An apparatus for holding stored material and for containing and detecting leaks of the stored material from the apparatus having a tank, a containment baffle, and a leak detection system. The tank includes a tank bottom having a continuous surface for supporting the stored material. A shell surrounds such stored material. The shell is disposed above the continuous surface of the tank bottom in continuous sealing contact therewith. The containment baffle is a baffle plate having a continuous surface for supporting the stored material. The baffle plate is disposed above the tank bottom and within the shell. The baffle plate is in continuous sealing contact with the shell so as to form a containment space between the baffle plate and the tank bottom. The baffle plate is rigidly supported above the tank bottom. A fill of aggregate material is interposed between the baffle plate and the tank bottom for structural support of the baffle plate. The leak detection system is isolated from the aggregate material within the containment space for detecting and sending signals in response to the presence of a stored material within the containment space.
