CALCULATION <br /> 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 seismic <br /> event. Seismic data used in the calculation is included as Table 2. The calculations are <br /> included as Appendix B. <br /> 5.1.1. Tank Specifications <br /> The 1,000-gallon AST primary and secondary compartments are manufactured from 10- <br /> gauge steel with a standard 1/8-inches in thickness, 55-inches in width, 113-inches in <br /> length and height of 48-inches. Containment Solutions (manufacturer) indicated that the <br /> tank weighs 2,200 pounds (lbs.) when empty. Waste oil is temporarily stored within the <br /> tank. 1,000-gallons of waste oil weighs approximately 450 lbs. The total seismic load of <br /> the tank is calculated to be 2,200 lbs. when empty and 2,650 lbs. when full. <br /> 5.1.2. Calculation Results <br /> The pounds of horizontal shear are calculated at approximately 668 pounds force (Ibf). <br /> The tank overturn moment is calculated at approximately-68,245-pound force foot (Ibf ft). <br /> The safety factor was calculated at approximately -8.6. The tank without additional <br /> components is sufficient to not spill during a potential seismic event for this area. Figure 3 <br /> shows the AST top and east side with dimensions. The seismic calculations are included <br /> as Appendix B. <br /> 5.2. SEISMIC ANCHORING <br /> AST seismic anchoring includes a total of three 6-inch by 3.25-inch by 0.25-inch steel <br /> plates bolted approximately 3.5-inches into the concrete slab which the tank rests on. <br /> Each steel plate is bolted to the forklift "feet" which are welded onto the tank. <br /> Additionally, the AST is surrounded on the east south and west sides by a six-inch brick <br /> wall within approximately 5-inches of those sides. The north AST side is approximately <br /> two feet from the Facility compressor and three feet from the north brick wall. The AST is <br /> shown in Figure 3. <br /> 5.3. INTEGRITY TEST FINDINGS <br /> Based on the calculations discussed in Section 5.1., the AST has sufficient integrity for <br /> its intended use. The total seismic load of the tank is calculated at 2,200 lbs. when empty <br /> and 2,650 lbs. when full. <br />
