Secondary containment is in good solid condition and electrical equipment is grounded. The <br /> tanks are integral secondary containment units rainwater does not impact the viability or stability <br /> of the tanks, nor is there an issue with freeboard precipitation as the tanks are self-contained <br /> vessels. There are storm drains at the fueling island which have containment boxes below grade <br /> and are emptied periodically or when full. <br /> Tank Foundation and Supports <br /> The foundation support legs of each of the Modem Welding Fireguard tanks were closely <br /> inspected, and found to be free of any <br /> damage or defect. There were no <br /> cracks at the foundations which would <br /> appear to lead to affecting the integrity <br /> of the tank support system. While <br /> there are some minor cracks in the <br /> pad, as is always to be expected with a <br /> concrete structures, the cracks appears <br /> slight surface cracks and do not <br /> indicate any affect on the stability of <br /> the support system nor of further <br /> spreading beyond its current length. As is always the case, where there is a crack in the <br /> underlying pad, any cracks which emanate or connect to the earthquake anchor bolts, should be <br /> monitored and repaired if they were <br /> 'p+r to continue to expand, or appear to <br /> affect the stability of the system. If <br /> the support system should be <br /> impinged by further cracking or by a <br /> seismic event, then an engineered <br /> professional repair should be <br /> undertaken to repair or replace any <br /> `!` ., .;;,.,,,��: condition which would affect the <br /> .. Nai. _...,, ability of the tanks to maintain their <br /> integrity or their stability. It is the normal condition of concrete slabs that they develop small <br /> hairline cracks over time as the ground beneath them is constantly in danger of shifting in a <br /> seismic zone, which is applicable to Lodi, CA. As such, a high degree of attention should be <br /> paid to any changes in the support system of the tanks. A weakened pad experiencing a seismic <br /> event could cause the tank or tanks to shift from their foundational supports and as aresult experience a spill or a leak £t isnotedherein that there does not appear to <br /> be such a danger in the immediatecondition of the pad and supports, but only <br /> that slight cracks in concrete bear visual <br /> monitoring over time and if required, <br /> of irmative action undertaken to maintain <br /> integrity of the tank systems.
