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 3000 gal caustic tank is shown in the <br />attached signed and stamped drawing. <br />Seismic/Anchoring findings: The tank as designed and operated, and the containment <br />area in which it is located, are adequately anchored and are seismically sound. <br />Initials: //, /.- <br />u� <br />Leak Test: <br />A leak test was conducted by filling the tank with 30% sodium hydroxide and <br />inspecting for leaks. There were no signs of leakage. <br />Tank Integrity: Based on the fact that the tank has contained caustic for several months <br />without signs of leakage, the tank has sufficient integrity for its intended use. <br />Initial./2 '2 " Cu w 1-> I <br />2`� 1=1 y . o•��ky 2 a I I ✓a ive <br />Tank Drawing: T �,.. -.: <br />130 Itos' � Q <br />F,-ft,.NS �fsed fb <br />a <br />ManWu�#` <br />crag <br />(N E S <br />To ?fin ►,.� �:a i h <br />W F/r�l this /w•t-4 h05e)H 'C.
