Therefore, no Mobilization/Demobilization <br /> costs are assigned. <br /> 2 It is assumed that there are four septic/leach field systems located at Coal Basin. Permit <br /> information indicates that the septic system at the Lamp House has a minimum tank <br /> capacity of 1,250 gallons, and an adsorption field area of 300 square feet minimum. <br /> Assume that all four systems are identical. <br /> 3 Assume 1�2 hour excavation time per sample location. <br /> 4 Assume 2 samples per system <br /> 5 Volume of 1250 gallon tank is 10.6 yd 3. Assume $1.81 per yard to fill, t/2 hour to break open <br /> top @ $49.00 per hour. <br />
