i .: .. <br />17. The topsoil respread costs will be the same as the overburden cost. <br />18. Your calculations are correct. The width of the continiaus-mining cutter <br />(excavator) will be 8.25 ft. This is a unique mining process in that the <br />cuts are narrow and long in addition to being continiously reclmmed. <br />19. Approximately 2 miles of railroad spur track will be installed in roughly <br />3 equal pnases. Yois estimate of $8.77/ft. for rm~oval is within reason. <br />Salvage of the rail and ties and miscellaneous hardware we estimate as <br />follows: <br />- 100 lb. rail @ 176 tons/mile is worth approx. $160/ton, F.O.B. site. <br />- 6" x 8" wood ties @ 3250 ea/mile are worth approx. $6/ea. <br />- hardware is roughly .2 ton/ton of rail @ the same salvage price. <br />This results in: <br />422.4 tons of rail and hardware @ $160/ton and 6500 ties @ $6/ea., <br />mPanin~v a net salvage price of $106,584 or $10.093/ft. <br />As a practical matter, we should asstime the cost for removal is equivi- <br />lant to the salvage material selling price. <br />20. The costs for grading topsoil should be approximately $ .50/BCY. <br />L1/2L. We attach copies of the certified deeds of surface owners and doc~anen- <br />tation indicating the mineral rights owners. The mineral right deeds <br />specifically exclude sand & gravel & related materials. <br />As you noted on this date, the ponds used for recycling the wash water <br />will have a 4 acre-ft. evaporative loss per year. We anticipate either <br />covering these surfaces with a plastic sheet or non-toxic ~rn,lsion, should <br />these losses exceed the water available to us, if the water is available, <br />these losses will be included with the water supply and augmentation plan, <br />currently being prepared by our water law firm. <br />If you have any questions, p1e <br />1 <br />
