<br />Financial Reporting Unit Rates
<br />Tenmile TSF
<br />Assumptions:
<br />(1) Trucks, Loader, and Dozers in 2000 Reclamation Cost Estimate are reasonable (Only change to 2000 cost estimate are equipment & labor rates)
<br />(2) Soil Replacement Thickness is 30' over 25% of (wet) cover area to 12" over 75% of (dry) cover area. Swell Factor = 1.215 from 2000 Cost Estimate
<br />(3) Revegetation is covered elsewhere
