Exhibit L — Reclamation Costs <br />DEWATERING: <br />Volumes per Tract: <br />Tract A: 641,371.13 cu.yds. x 27 = 17,317,020.51 cu.ft. x 7.48 gal /cu.ft. = 129,531,313 gal. <br />Tract B: 214,847.38 cu.yds. x 27 = 5,800,879.26 cu.ft. x 7.48 gal /cu.ft. = 43,590,577 gal. <br />Tract C: 1,651,035.02 cu.yds. x 27 = 44,577,945.54 cu.ft. x 7.48 gal /cu.ft. = 333,443,033 gal. <br />Tract D: 415,226.24 cu.yes. x 27 = 11,211,108.48 cu.ft. x 7.48 gal /cu.ft.= 83,859,091 gal. <br />Y- = 590,224,014 gal. <br />Avg. = 590,224,014 gal. - 4 = 147,556,003.5 gal x $ 0.000026 /gal. discharge (refer to <br />Kurtz est. utilizing similar pump and rates.) <br />Total Average Life of Mine Discharge Cost = $ 3,836.45 <br />NOTE: The basins resulting from extraction will be reclaimed in an unlined state, since <br />the operator retains sufficient water resources to do so. The basins may be lined or <br />otherwise segregated from the area groundwater as an option to the approved permit, <br />in order to liberate the water otherwise retained to supplement loss from evaporation in <br />the unlined state. Since sufficient water resources exist, the option to line the resulting <br />basins at an unspecified time during the life of the permit is retained under this <br />application and as part of the approved permit. <br />GRADING: <br />As stated in Exhibit D — Extraction Plan: <br />A 1600± linear foot standard morphing extraction front is comprised of <br />a 1.25H:1V face along an approximate 800 -1200± linear foot <br />advancing; wall with trailing side slopes up to 400 total linear feet <br />combined along either side of the advancing wall where it serves to <br />define the predetermined boundary of the extraction limits shown on <br />Exhibit C -2: Extraction Plan Map. Concurrent grading follows <br />immediately behind the trailing side slopes as they occur along the <br />extraction limits. This morphing extraction front, with its advancing <br />wall, trailing side slopes, and concurrent reclamation along the <br />extraction limits is approximate for all active Tracts. <br />The 1600± linear foot total extraction front is ' morphing' in that the <br />total linear feet of the front will not exceed 1600± linear feet, however, <br />the advancing wall and side slopes may deviate from the 'standard' <br />Varra Companies, Inc.
