<br /> <br />Exhibit L -Reclamation Costs <br />The total permit area is 30.06+/- acres. Of this, the disturbed area will be <br />approximately 17.3 acres. However, as discussed in Exhibit C, concurrent reclamation <br />will occur. A maximum of 10 acres will be disturbed at any time (approximately five <br />acres of pit, and five acres of miscellaneous disturbance including the detention pond <br />and soil/overburden/product stockpile areas). The reclamation tasks to be pertormed <br />are described in Exhibit E. <br />Replace overburden on 5 ac. Total of approx. <br />121,000 c.y. of overburden to be moved using a Cat. <br />637D scraper. Average one-way haul distance of <br />250 ft.. From Cat. pertormance curves, approx. 600 <br />c.y.lhr. production. Approx. 202 hrs. required at $180/ <br />hr. 36,360 <br />• Final grade pit slopes to 3:1. Approx. 750 lin. ft. of <br />slope to require an average of about 5.1 c.y./lin. ft. <br />moved. Total of approx. 3,825 c.y. to be moved <br />using D-9 dozer (push distance less than 50 ft. ave.). <br />From Cat. performance curves, the dozing production <br />for this type of grading is estimated to be approx. 600 <br />c.y./hr. Approx. 6.5 hrs. required at $140/hr. 910 <br />• 8ackfill and grade the secondary detention pond. Approx. <br />1,600 c.y. to be moved using D-9 dozer (ave. push <br />distance of about 100 ft.). From Cat. performance curves, <br />estimated production is approx. 550 c.y./hr. Approx. <br />3 hrs. required at $140/hr. 420 <br />• Rip access road. Use D-9 Cat. with multi-shank ripper, <br />12 in. ripping depth, 12 ft. ripping width. Approx. 1,056 <br />sq. ft./min. ripping production (from Cat. performance <br />handbook). For 0.7 ac. of road, approx. 0.5 hr. required <br />at $140/hr. 7 0 <br />-27- <br />
