<br />Exhibit L - Reclamation Costs <br />The worst case condition (ie. maxim~an disturbance with no reclamation) <br />is assumed for calculating the estimated financial warranty for this site. <br />The total permit area is 61.02 +/- acres. Of this, approximately 52.78 <br />(say 52.8) acres will be disturbed and require reclamation. The <br />reclamation tasks to be performed are described in Exhibit E. <br />- Final grade pit cut slopes to 4:1. Assure slope <br />length of about 4,730 ft. and cut and fill grading <br />to be done. Total of 42,236 c.y. to be moved <br />(ave. 8.93 c.y./lin. ft) using D-9 dozer (ave. push <br />distance of about 90 ft.). Est. performance using <br />straight blade of 350 c.y./hr. (Cat. performance <br />curves; includes correction factors). Approx. <br />120.6 hrs, required (say 121 hr.) at 5140/hr. 516,940 <br />- Miscellaneous minor smooth grading on the remainder <br />of the floor of and perimeter of the affected area. <br />Est. 8 hr. required using D-9 dozer at $140/hr. 1,120 <br />- Grade misc. runoff control berms and other misc. <br />ditches. Est. 8 hr. required using D-9 dozer at <br />5140/hr. 1,120 <br />- Replace ave. 6 in. topsoil on 52.8 ac. (42,592 cu. yd.) <br />using a 637D scraper and D-9 dozer. Tasks proport- <br />ioned at approx. 69.7$ of effort for scraper (used for ~/~^'` <br />hauls longer than about 200 ft (ave. one way of about 400 G,,,a~Q.P.e , <br />ft.); and 30.3 of effort for dozer (used on side slopes ~~~ ` <br />and push distances <200 ft. (ave. 100 ft.)). Est. _1 <br />performance for scraper of 350 c.y./hr. (Cat. performance <br />curves; includes correction factors. Approx. 98.9 hrs. <br />required (say 99 hr.) at $250/hr. Est. performance <br />for D-9 with straight blade of 550 c.y./hr. (Cat. <br />performance curves; includes correction factors). <br />Approx. 77.4 hrs. required (say 78 hr.) at 5140/hr. 35,670 <br />- Two soils tests obtained from Colorado State <br />University Soils Lab. Cost of standard test and <br />shipping. 45 <br />- Fertilizer for 52.8 ac. per soils test but for purposes <br />of bond assume that 87 lbs./ac. 46-0-0 (at 50.19/lb.), <br />89 lbs./ac. 0-45-0 (at 50.18/lb.) and 65 lbs./ac. <br />0-0-62 (at 50.16/lb.), current price is $42.95/ac. 2,268 <br />-25- <br />
