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 are located, are adequately anchored and are seismically sound. <br />Initials: <br />beak '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: K5 <br />Tank Drawing: <br />Facing <br />N)ESW <br />b <br />Tank Diameters: 11 ft 10 in, 4 ft and 4 ft <br />Tank Ileight: 15 ft 3 in, 5 ft 7 in and 4 ft <br />Tank Gross Capacity: 8285 gallons <br />r#►o°� �!ci d� <br />t.t,��ri 1c1�,tfL <br />California 'Tank Lines, Inc.
