Seismic/Anchoring: <br /> Tank anchorage is specifically designed for linear and crosslinked polyethylene <br /> tanks, and consists of bolts or metal clips anchored to the concrete foundation <br /> pad, with cables running between the clip and hold downs on the top of the tank. <br /> These are designed by a civil/structural engineering firm,and are purchased from <br /> the tank manufacturer, Snyder Industries or Poly Processing Co. The system for <br /> the wastewater cone bottom tank is shown in the attached signed and stamped <br /> drawings. It should be noted that the structural calculations completed by Paul <br /> Durand,P.E., are for zip code 92704 with more stringent seismic requirements <br /> than Stockton,and thus provide a significant safety factor in this case. <br /> Seismic/Anchoring findings: The tanks as designed and operated,and the containment <br /> areas in which they arc located,are adequately anchored and are seismically sound. <br /> Initials: <br /> Leak'fest: <br /> A leak test was conducted by filling the tanks with wastewater and inspecting for <br /> leaks. There were no signs of leakage. <br /> Tank Integrity: Based on the fact that the tanks are new(purchased in 2016)and have <br /> contained wastewater without signs of leakage,the tanks have sufficient integrity for <br /> their intended use. <br /> Initials: KS <br /> Tank Drawing: , <br /> f� <br /> UI�I GJ��tE <br /> i <br /> Facing - — <br /> (N-)ESW <br /> Tank Diameters: I l ft 10 in,4 ft and 4 ft <br /> Tank Height: 15 ft 3 in,5 ft 7 in and 4 ft <br /> Tank Gross Capacity: 8285 gallons <br /> California Tank Lines, Inc.
