Abstract of the Disclosure A containment device for minimizing soil contamination in filling underground storage tanks, comprises a bucket member, a bottom member and a bellows connection between the bottom member and a riser pipe extension. These elements comprise an upwardly open spillage container. A lower bellows connects the bottom member and the riser pipe extension, comprising a lower chamber. The containment device is mounted on the riser pipe of an under- ground tank by threading the lower end of the riser pipe extension thereon. A valve controlled passage, through the bottom member, permits spilled fuel to be drained from the spillage container into the lower chamber and then through openings in the riser pipe extension into the storage tank. The bottom member is releasably secured to the bucket member and the bellows are releasably clamped to the riser pipe extension, to permit these items to be removed from the bucket member for repair and replacement. In an alternate embodiment there is no lower chamber and the upper bellows is releasable clamped directly to a storage tank riser pipe. In another embodiment the upper and lower bellows are formed as portions of an elastomeric separating member. In order to control the installed orientation of the bucket, adjustable mechanism is provided for establishing a desired position of the upper end of the bucket member relative to the riser pipe extension. Also described is a bayonet connection between the bucket member and a mounting rim; a dam arrangement from preventing ground water from entering the spillage container; and wire anchors for insuring a firm connection between the containment device rim and a concrete apron which overlies the storage tank.
