Abstract
Abstract A storage tank system especially useful for storing gasoline has an auxiliary enclosure assembly. The system comprises a storage tank, preferably with a tank cover for gaining ingress into the storage tank, a sleeve positioned on the storage tank, a sleeve cover with an entry cover in a mid-portion thereof, preferably a dirt shield extending from the sleeve cover to ground level, a drip sump compartment positioned on the cover of the sleeve and a fill line extending through the drip sump compartment and sleeve. The assembly allows ready access to the area within the sleeve for inspection and repair purposes and can provide ready access to the interior of the tank. It also provides protection and containment for access lines leading through it.

Claim 1
Independent Claim
194 words
A storage tank system having an auxiliary enclosure assembly for an entry way to the tank and access lines leading to the tank, said system comprised of: (a) a storage tank for storing liquid, said storage tank having access lines into the tank; (b) a sleeve positioned on the storage tank to enclose the access lines, said sleeve positioned so as to keep a sleeve area therewithin substantially free of surrounding soil; (c) a sleeve cover attached to the sleeve to form the sleeve area therewithin, further said sleeve cover having a removable entry cover in a mid-portion thereof so as to gain access to the access lines; (d) a drip sump compartment positioned on the sleeve cover of the sleeve, said drip sump compartment capable of catching spills and drippings during a filling operation; and (e) a fill line for adding liquid to the tank which extends through the drip sump compartment and sleeve area, said fill line having an opening at one end within the drip sump compartment for receiving liquid during a filling operation and a second opening at another end which leads directly to the interior of the storage tank.
