some minor hairline fractures in the shell, also. Close observation did not detect any problematic <br /> structural cracks and the overall condition of the shell was in very good shape. <br /> There appear to be no issues with any of the tanks' primary vessels, as no signs of corrosion or <br /> leaking are present. Any maintenance indicated in this section should be scheduled for this <br /> coming year when weather conditions allow. <br /> Onan Cummins: The Onan Cummins Generator-Fuel Tank System tank (tank A) has no <br /> evidence of fractures, and no structural cracking on the outer steel shell. Upon close visual <br /> inspection,there is no evidence of any weld breaks, punctures, cracks, or other structural damage to the <br /> tank. The openings on the tank are properly closed with appropriate equipment or with plugs. <br /> fracturing. There is some minor external corrosion taking place on the outer shell of the fuel <br /> tank, but such corrasion does not appear to affect the tank integrity in any manner. It is <br /> recommended that repainting the exterior of the fuel tank should be undertaken during regular <br /> preventative maintenance operations so as to min mme external corrosion and extend the life of <br /> the system. The supports of the system have springs which function when the system is under <br /> operation, to reduce vibration damage and thus limit the danger of metal fatigue. The springs do <br /> exhibit some level of corrosion and the entire set of springs should be replaced at such time as <br /> when the level of corrosion indicates that this corrosion could inhibit the effectiveness of the <br /> springs functions, which ultimately would result in increased vibrations during operation and <br /> have an impact on the integrity of the welds and/or the steel plates which comprise the tank shell. <br /> There is no indication that this issue is imminent, but should be monitored over time and the <br /> response undertaken when reasonable and practicable. Close observation did not detect any <br /> problematic structural cracks and the overall condition of the shell was in very good shape. <br /> There appear to be no issues with any of the tanks' primary vessels, as no signs of corrosion or <br /> leaking are present. Any maintenance indicated in.this section should be scheduled for this <br /> coming year when weather conditions allow. <br /> Tank Equipment <br /> Piping: <br /> ConVault Tank: Piping for the 6000 gal. ConVault Tank appears to be entirely within the <br /> confines of the system and thus are not subject to outside forces impacting the operations of that <br /> system. The piping between this Tank and the Dispenser/Pump devices is well protected, <br /> painted, and travels down the end of the AST to the back of the dispenser. There is no piping <br /> exposed from the 6000 gal. ConVault Tank which would be likely to be contacted either by <br /> passersby or by inadvertent equipment contact. The ConVault 6000 gal AST (Tank A) contains <br /> and operates dispensing operations to vehicles The operations work thrn an electronic card lock <br /> system From the pump system, there is a 3/8 line back to the primary fuel vessel for the <br /> operation of a Weights & Measures dispensing operation. The piping is fully secured and <br /> protected and shows no evidence of damage or corrosion. <br /> Both Tanks and the fuel dispensers are protected by concrete bollards surrounding the ASTs and <br /> protecting both equipment and AST from vehicle impact. It is noted that at the dispenser for <br /> gasoline, the pump dispenser the hose hanger is raised in compliance with CARB regulations, <br /> and that there is adequate protections from impact and from accidental discharges..
