'YM 3 <br /> wa. ' <br /> =+^a e <br /> W. <br /> 1 <br /> Emissions Calculations <br /> RTX&E Compounds <br /> i <br /> Assumptions <br /> is a) Concentrations averaged for the boreholes and number of <br /> samples for which data is available (i.e. average for <br /> �- minimum excavation utilized data for boreholes #3 and <br /> #4 which is a total of seven sample points) . For any <br /> ND value, a value of 1 ppm is utilized. <br /> b) Value, for volatilized lbs, are based on volatilization <br /> percentages derived from sesoil results (ref: Fleisher <br /> et al, 1986, attached) <br /> C) lbs. per day values are derived from excavation dura- <br /> tion estimates - 3 days for minimum extent and 8 days <br /> for maximum extent. <br /> d) These calculations assume that all volatilization <br /> occurs during excavation. <br /> F ' Benzene: <br /> W� 1• Average Concentration <br /> r o Minimum extent - [240 nm + 6(1Ppm) ]/(7ea) 35.14 ppm. <br /> o Maximum extent - (BH #3,4,5,6,8) - [240ppm + <br /> f 14(Zppm) ]/(15ea) = 16.93ppm. <br /> 2. Volume of Excavation (2600 lb/yd3) <br /> i <br /> d Minimum extent - 250 yd3 x 2600 lb/yd3 = 910,000 lbs. <br /> o Maximum extent - 3500 yd- x 2600 lb/yd3 = <br /> 9,100,000 lbs. <br /> 3• lbs. of Benzene emitted from site (volatilization percentage <br /> = 62%) <br /> o Minimum extent - 910,000 lbs x .00003514 x .62 w <br /> w: 19.83 lbs. <br /> a Maximum extent - 9,100,000 lbs x .00001693 x .62 = <br /> 95.52 lbs. <br /> 6. <br /> 4. lbs, per day for excavation project <br /> o Minimum extent - 19.83 lbs/(3 days) = 6.61 lbs/day. <br /> i o Maximum extent - 95.52 lbs/(8 days) = 11.94 lbs/day. <br /> ya.i <br />
