wood. <br /> At a minimum provide the following: <br /> Calculation of the seismic load of the tank: <br /> 5.89 kips (ASCE 7-16) (Attachment 3) <br /> Calculation of overturning moment of tank <br /> 164.97 k-in (ASCE 7-16) (Attachment 3) <br /> Safety Factor: 3.66 (ASCE 7-16) <br /> Demonstration that the resisting moment is greater than the overturn moment: <br /> Safety Factor = (resisting moment/overturning moment) = > 2 <br /> Seismic load variables: <br /> In doing a seismic load calculation, specify <br /> Variables: <br /> Site Class (Section 11.4.2, ASCE 7-16) = D <br /> Occupancy Importance Factor (Table 1.5-2, ASCE 7-16) = I p= 1.25 <br /> Site Design Response Acceleration (Section 11.4.5, ASCE 7-16) = SDS = 0.61 <br /> Damping for sloshing force (Section 15.7.2, ASCE 7-16) = 0.5% <br /> Distance to Known seismic source = >15 km <br /> Specific Gravity of Tank's Liquid = 0.94 <br /> Specific Gravity of Shell material= >> 1 <br /> Coefficient of Friction (concrete on concrete surface, Section 22.9.4.2, ACI 318-14) = µ = <br /> 0.6 <br /> Tank Height = H = 52 inches (including feet) <br /> Tank Length = L = 132 inches <br /> Tank Width = W = 68 inches <br /> Assessment Conclusions: <br /> The used oil tank system has sufficient structural integrity; is acceptable for the <br /> transferring, storing, and treating of hazardous waste (used oil); and the tank and <br /> containment system are suitably designed to meet the requirements cited above (22 <br /> CCR §66265.192). <br /> Given an industry and manufacturer estimated 40-year service life and the subject tank <br /> history and condition, the tank system has an estimated remaining service life of at least <br /> 5 years. <br /> This assessment is valid for a maximum period of five (5) years in accordance with 22 <br /> CCR §66265.192(h). <br /> Wood Environment & Infrastructure Solutions, Inc. 1,000 Gal.
