<br />Material to be used <br />Total Fuel Storage <br />Berm Height <br />Width of Berm <br />Length of Enclosure <br />Width of Enclosure <br />Conversion factors <br />7.48 gal=1 FT3 <br />12.00 inches = <br /> <br />Calculation Page <br />Road Base <br />50,000.00 gal. <br />1.50 feet <br />4.00 feet <br />UNKNOWN <br />50.00 feet <br />(liquid) <br />1 foot <br />Asumptions <br />tanks and equipment located in bermed area <br />displace 250.00 FT3 <br />CALCULATIONS <br />Capacity Needed in Bermed area: <br />Use 55,000 gal as design figures to allow for complete failure <br />for all tanks. <br />volume = 55000/7.48 = 7352.94 USE 7400 FT3 <br />wall length = 7400/(1.5x50)= 98.66 feet USE 100.00 feet <br />Capacity of designed berm area: <br />cubic area = 100x50x1.5 = 7,500 FT3 <br />capacity = (7500-250 FT3)x 7.48 gal/FT3 = 54,230 gal. <br />Free board within bermed area assuming total failure of all storage <br />facilities. <br />Capacity of bermed area -total fuel storage = <br />54,230 - 50,000 = 4,230 gal <br />volumn of fuel 50,000/7.48 = 6,684.49 FT3 USE 6685 FT3 <br />Depth within bermed area= (6685x12)/(SOx100) <br />= 16.04 inches <br />free board= 18.00 inches-16.04 inches = 1.96 inches <br />CONCLUSION: <br />1.60 inches of free board would exist should all tanks failed <br />at once without being detected. If a major spill were to occure <br />immediate steps would be taken to recover as much of the spilled <br />fuel as possible, leaving little chance of having to contain the <br />entire 50,000 gallons. We have designed this bermed area to handle <br />this worst case possibility because we understand the problems <br />caused should any fuel reach the Eagle river. <br />4 <br />
