<br />Exhibit L - Reclamation Costs <br />The worst case condition (ie. maximum disturbance with no reclamation) <br />is assumed for calculating the estimated financial warranty for this site. <br />The total permit area is 50.94 +/- acres. Of this, only approximately 35.6 <br />(say 36) acres will be disturbed and require reclamation. The reclamation <br />tasks to be performed are described in Exhibit E. <br />- Pinal grade pit cut slopes to 3:1. Assume slope <br />length of about 1,300 ft. and cut and fill grading <br />to be done. Total of 74.820 c.y. to be moved <br />(11.4 c.y./lin. ft) using D-9 dozer (ave. push <br />distance of about 110 ft.). Est. performance using <br />straight blade: 370 c.y./h r. (Cat. performance <br />curves; includes correction Factors). Approx. <br />40.1 hrs. required (say 41 hc.) at $180/hr. $7,380 <br />- Miscellaneous minor smooth grading on the remainder <br />of the floor of and perimeter of the affected area. <br />Est. 24 hr. required using D-9 dozer at $180/hr. 4,320 <br />- Grade misc. runoff control berms and other misc. <br />ditches. Est. 4 hr. required using D-9 dozer at <br />$180/hr. 720 <br />- Replace ave. 6 in. topsoil on 36 ac. (29,040 cu. yd.) <br />using a 637D scraper and D-9 dozer. Tasks proport- <br />ioned at approx. 809, of effort for scraper (used for <br />hauls longer than about 200 ft (ave. of about 400 <br />ft.); and 207, of effort for dozer (used on side slopes <br />and push distances <200 ft.). Est. performance for <br />scraper of 340 c.y./hr. (Cat. performance curves: <br />includes correction factors. Approx. 68.3 hrs. <br />required (say 69 hr.) at $300/hr. Est. performance <br />Eor D-9 with straight blade of 480 c.y./hr. (Cat. <br />performance curves: includes correction factors). <br />Approx. 12.1 hrs. required (say 13 hr.) at $180/hr. 23,040 <br />- Two soils tests obtained from Colorado State <br />University Soils Lab. Cost of standard test and <br />shipping. 45 <br />- Fertilizer for 36 ac. per soils test but for purposes <br />of bond assume that 87 lbs./ac. 46-0-0 (at $0.19/lh.), <br />89 lbs./ac. 0-45-0 (at $0.18/16.) and 65 16s./ac. <br />0-0-62 (at $0.16/lb.), current price is $42.95; ac. 1,547 <br />-23- <br />
