EXHIBIT L <br /> RECLAMATION COSTS (revised 4/3 0/18) <br /> The following information depicts a worse case scenario when it <br /> would be most expensive to reclaim the site in the first ten (10) <br /> year after mining starts . This reclamation cost estimate is <br /> based on mining starting in the old Plant Site area and when the <br /> pendula between the small lake and the larger lake has been mined <br /> and mining has been started on a portion of the west lake start- <br /> ing at the western end of the pre-law dirt pile . Map Exhibit L - <br /> Reclamation Cost Map shows that the old Plant site covers 12 . 32 <br /> acres which was used historically as an industrial and Concrete <br /> Batch Plant area, 1 . 57 acres is pre-law area that needs no <br /> reclamation should it not be redisturbed and 0 . 63 acres has been <br /> graded along where the new lake was created. The post 1981 lake <br /> area covers 14 . 80 acres, there is 9 . 03 acres of pre-law dirt pile <br /> and reclaimed lake shores in the northeast part of the mine fora <br /> total of 38 . 35 acres ± . While the area needing grading is less <br /> then what exists when the mine opens, there is 350 feet of <br /> working face needing grading 3h to lv. <br /> At this time in the life of the mine the old plant site area <br /> 12 . 32 acres, will need grading and shaping (no resoiling since <br /> non exists now) and some equipment will need to be disposed of <br /> either by burying it in the case of stockpiled concrete tear out <br /> or hauled to a scrap yard in the case of scrap material . The <br /> concrete pads would remain for use by the landowner as a base for <br /> sheds or building they may choose to construct at a later date . <br /> The old concrete wash out area will remain since it will be the <br /> base for the boat ramp and beach area and 350 feet of working <br /> face will need grading 3h to iv. The remaining 26 . 03 acres will <br /> be pre-law undisturbed area, lake area and reclaimed area done <br /> under the existing permit . <br /> The plan is to grade the final lake slopes as mining pro- <br /> gresses so we expect to have no more then 350 linear feet of <br /> sloping that would need to be done to complete lake shore recla- <br /> mation. Due to the depth of the lake this would involve pushing <br /> approximately 2 , 016 cy of material into the lake to create the <br /> 3 : 1 slope along the working face . No additional material would <br /> need to be imported since the material would come from the area <br /> above the working face as described in the reclamation plan. <br /> This is an attempt to set the bond so there is flexibility <br /> to operate the mine without reevaluating the bond yearly over the <br /> next 10 years . As mining progress the actual grading costs go <br />
