Seismic data used in the calculation is included as Table 5. The calculations are <br />included as Appendix A. <br />5.1. SEISMIC CALCULATION <br />The seismic analysis is calculated by using AST specifications and finding the horizontal <br />shear, the overturn moment and the safety factor the AST will withstand during a <br />seismic event. Seismic data used in the calculation is included as Table 5. The <br />calculations are included as Appendix A. <br />5.1.1. AST Specifications <br />The 1,000 -gallon AST primary and secondary compartment materials of manufacture <br />are discussed in Sections 2.1.3 and 3.1. The AST weighs of 1,895 pounds (lbs) when <br />empty is calculated, by extrapolation, using a similar use AST. Waste oil is temporarily <br />stored within the tank. When the AST is full, 1,000 -gallons of waste oil weighs <br />approximately 7,500 lbs. The total seismic load of the tank is calculated to be 975 Ib <br />force (Ibf) when empty and 9,395 Ibf when full. <br />5.1.2. Seismic Calculation Results <br />The pounds of horizontal shear are calculated at approximately 477.5 Ibf. The tank <br />overturn moment is calculated at approximately -1,590 Ibf foot (ft). The safety factor was <br />calculated at approximately 2.2. The tank, without additional components, is of sufficient <br />weight to not spill during a potential seismic event for this area. Figure 1 shows the AST <br />top and north east sides with dimensions. The seismic calculations are included as <br />Appendix A. <br />5.2. SEISMIC ANCHORING <br />AST seismic anchoring is not required based on seismic shear moment and over turn <br />calculations, discussed in section 5.1. <br />
