Per the approved reclamation plan the reclaimed southwest facing slope on the north side of <br />the pit must be graded to 3H:1V, and a level area created southwest of the pit. All other slopes <br />are to be graded to 2H:1V. <br />An approximate volume of material necessary to backfill the pit to create a level area and grade <br />the north pit slope to 3H:1V is estimated at 45,370 yds.3 <br />Calculation: (60 ft. x 20 ft.) + (202 ft.) + .5(10 ft. x 30 ft.) = 1,750 ft.2 <br />1,750 ft.2 x 700 ft. = 1,225,000 ft.3 = 45,370 yds.3 <br />1750 feet 3 <br />1750 feet 2 <br />700 feet <br />20 feet <br />40 feet <br />67.5 feet <br />Ridgeline --? <br />700 feet <br />30 feet <br />20 feet <br />30 feet <br />20 feet -' '- 20 feet <br />60 feet
