Calculation Sheet October 6, 1989 <br /> Sheet 1 of 1 <br /> 89-014 <br /> 880 Victor Road <br /> Lodi Ca <br /> Problem: <br /> Calculate the maximum amount of soil to be generated from tank <br /> replacement activities at the site. <br /> Assume: <br /> 0 All fill material in existing tank location contains petroleum <br /> hydrocarbons. <br /> 0 50 cubic yards of fill material is contained in the piping <br /> trenches. <br /> 0 Existing tank location is 421X 30 ' X 141 . <br /> 0 Soil expansion factor of 1. 4 . <br /> A) Calculate volume of existing tank location. <br /> 42 ' X 30 ' X 14 ' = 17 , 640 ftz = 653 . 3 yd.3 <br /> B) Calculate and subtract volume of tanks from volume of excavation. <br /> Tank <br /> No. Gallons <br /> 1 8000 <br /> 2 7500 <br /> 3 5000 <br /> 4 5000 <br /> Total gallons: 25, 500 = 3400 ft = 124 yd3 <br /> 653 . 3 yd3 - 124 yd3 = 529 yd3 <br /> C) Add soil from line trenches to volume of soils from excavation <br /> and multiply by soils expansion factor. <br /> 529 yd3 + 50 yd3 = 579 yd3 X 1. 4 = 810 yd3 <br />
