The general condition of the primary containment is good <br /> and the secondary containment vessel is in good shape without any evidence of leaks, fractures, <br /> or corrosion affecting containment. There are minor hairline fractures on the external <br /> concrete of both the 6000 gal. ConVault top & sides which should be monitored and if <br /> necessary, repaired to prevent them from expanding and affecting the secondary <br /> containment The tank sits under a steel cover which prevents most rainfall from falling on the <br /> top of the tank and causing issues with freeze-thaw concrete problems and with water finding its <br /> way into the interstice. There are no fresh hairline fractures nor are there any structural cracks <br /> on the shells of the tanks, There is minor debris in the area, for normal conditions in a tank that <br /> it outside and tangentially subject to weather conditions. However, as the area contains no <br /> fugitive combustible material from other sources within the containment area, slight debris <br /> does not appear to be an impactful issue.. <br /> The concrete floors, upon close visual - <br /> inspection have no discernible <br /> integrity-affecting structural cracks <br /> or concrete spalling. The ASTs sit <br /> on a concrete pad and under cover <br /> where rainwater is generally prevented <br /> from entering or corroding the system <br /> from on top or from beneath. The <br /> concrete flours are in very good shape <br /> and the tanks are secured to the pads <br /> appropriately and grounded. The 6000 <br /> gal ConVault and other fuel tanks sit <br /> side by side on a continuous pour pad, <br /> with space visual inspections and <br /> maintenance operations between them. <br /> The concrete pad beneath the tank are <br /> clear, easily visually inspected and show no residue of diesel product, or any other petroleum <br /> product stains,indicating no leaks from the tanks, and no spills onto the concrete pad.
