Seismic/Anchoring: <br /> Tank anchorage is specifically designed for crosslinked polyethylene tanks,and <br /> consists of metal clips bolted to the concrete foundation pad, with cables running <br /> between the clip and a tension ring on the top of the tank. This design, completed <br /> by a civil/structural engineering firm,has been used successfully for polyethylene <br /> tanks for many years. The system for the wastewater storage tanks is shown in the <br /> attached signed and stamped drawing. <br /> Seismic/Anchoring findings: The tanks as designed and operated,and the containment <br /> areas in which they located, are adequately anchored and are seismically sound. <br /> Initials: !` <br /> Leak Test: <br /> The tanks were used previously to contain sodium chlorite. When filled with <br /> sodium chlorite they were inspected for leaks. There were no signs of leakage. <br /> Tank Integrity: Based on the fact that the tanks have contained sodium chlorite for <br /> several years without signs of leakage,the tanks have sufficient integrity for their <br /> intended use. <br /> Initials - <br /> Tank Drawing: <br /> 0- 06 0�7 <br /> • <br /> t X <br /> 120 12"0 r, WWI <br /> P1 Sep <br /> r�. <br /> F cing <br /> N E S W <br /> Tank Diameters: 12 feet and 4 feet <br /> Tank Height: 14 ft. 2 in. and 4 feet <br /> Tank Gross Capacity: 10,300 gallons and 350 gallons <br /> Superior Tank Wash Wastewater Storage Tanks <br />
