2. Talus Only about one-fifth of the open pit walls will be stable enough to permit any attempt at revegetation. The plan indi- cates that , if practical, AMAX will (possibly by helicopter) attempt to distribute some seed and fertilizer on those stable areas only and have therefore allowed $250/acre for talus acreages as a cost . 3 . Maintenance Fertilization (Man-days) Labor Material Total . 2 $ 25 $ 15 $ 40 B. Haul and Construction Related Costs 1 . Rock Haul Hauling costs vary dramatically and are therefore very difficult to predict . The costs of hauling rock included herein were derived from the average cost for all highway construction jobs done under contract to the Colorado State Highway Department for the year. State costs were $. 16/ton for loading and spreading and $.13/ton mile for hauling. We added $ . 03/ton mile for road construction , maintenance and inflation. 2. Topsoil The costs of hauling and spreading topsoil were calculated at $1 . 40/yd3 averaged for all haul distances . The budgeted quantities shown for the spec�fic sites add up to the total basic commitment of 550 ,000 yd , but the quantities shown for each site may or may not be used at that site . AMAX reserves the right to determine where the soil can be used most effectively. 3 . Flood Control Robinson Pond $ 660 ,000/ Tenmile Pond 700 ,000' Mayflower Pond 3 ,140 ,000✓ Total $4,500 ,000 C . Site Specific Reclamation Costs The following are estimated costs of completing the reclamation of each specific site. Area numbers are correlated to the maps. Costs are 1985 dollars . Acreages of disturbance are projected through 1986. Areas partially revegetated are itemized and assigned appropriate costs to complete the reclamation from the present state of progress . As in the past , "buffer" constitutes lands reserved for future possible disturbance. -2-
