The concrete floors, upon close visual inspection have no discernible integrity affecting structural cracks or concrete spatting. Both ASTs sit on concrete pads and are not under cover where rainwater would be generally prevented from entering or corroding the system from on top or from beneath. However, as UL 2085 tanks are double wall tanks with integral secondary containment, the issue of rainwater entering the tanks' inner systems is negligible or non-existent, as rainwater would merely run off the top of the tank due to its cylindrical design. The concrete floors are in very good shape, with only minor surface cracks (to be expected with concrete pads) and the tanks are secured to the pads appropriately and grounded. The two 25,000 gal Modem Welding Fireguard tanks sit side to side on a generally r continuous pour pad, with space between them for inspections, maintenance, or access for repair operations.Nearby next to the fuel building, there is a pallet of ancillary diesel support product, Diesel Exhaust Fluid (DEF ISO 22241) which is designed to reduce NOx exhaust. Those DEF products are mixed in a 700 gallon Poly tank which sits behind the Pallet to be used as a fuel additive when filling the semi-trucks which is electronically pumped from the Poly tank container into the fuel tank of the trucks via dispenser at the fueling islands. ASTs sit on pad with a lowered drainage system running the direction of the tank layouts and tending to pool beneath the tanks, not to any sewer or runoff connections. The concrete pads beneath the tanks are clear, easily visually inspected and show no residue of diesel product, or any other petroleum product stains, indicating no leaks from the tanks, and no spills onto the concrete pad. Weeds and foliage beneath the tank have been removed, and the pad is clear from vegetation. All ASTs are UL 2085 listed integral secondary containment fuel storage tanks. All of the secondary containment appears to be in very good operating order and in good shape. As previously mentioned, the hairline cracks in the concrete are normal conditions for concrete and should be watched over time to avoid any impact on the stability of these tanks. Both tanks are secured to the concrete pad, and as such are unlikely to move in a frost heave, should weather conditions be such that the danger could otherwise appear. Both ASTs (Aboveground Storage Tanks) appear to have been painted for their original condition and installation, and the coatings appear to be holding up well. Small areas of cracking or flaking appear on the surface of the ASTs but do not present a current hazard. All nipples on top of the tank appear to be adequately sealed via welds, with little or no danger of water migrating into the system and causing corrosion incidents. . While, with a Modern Welding Fireguard, there was a slight expectation of some moisture during the test operations, it was found that there was no water or any other liquid present in the interstice. As a result, it appears that fugitive moisture incidents have been adequately addressed and prevented. Moisture issues are recommended to be continually addressed as part of ongoing preventative maintenance, that the interstice on this AST be checked regularly for any detectable problems.
