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. These are designed by a <br />civil/structural engineering firm, and are purchased from the tank manufacturer, <br />Poly Processing Co. The system for the wastewater storage tanks is shown in the <br />attached signed and stamped drawings. <br />Seismic/Anchoring findings: The tanks as designed and operated, and the containment <br />areas in which they are located, are adequately anchored and are seismically sound. <br />Initials: �j�/ <br />Leak Test: <br />A leak test was conducted by filling the tank with wastewater and inspecting for <br />leaks. There were no signs of leakage. <br />Tank Integrity: Based on the fact that the tanks have contained wastewater for several <br />years withou signs of leakage, the tanks have sufficient integrity for their intended use. <br />Initials: <br />Tank Drawing: se /✓a- Y a f� Con n t4 ,` r, M & `� <br />i <br />!- Q r ,�, Q ►� Sr <br />10 � ll U <br />12 WWI � Zr <br />Facing <br />l)E S W <br />Tank Diameters: 12 feet and 10 feet <br />Tank Height: 14 ft 2 in and 10 ft 3 '/z in <br />Tank Gross Capacity: 30,800 gallons <br />y✓ W — �,i/u SIC wa to <br />C CoAe do forv+ <br />California Tank Lines, Inc.
