The purpose of this letter is to provide addition information on the <br />proposed mining operation in order to reduce the reclamation liability. The information <br />provided herein is based on the phone conversation you had with Greg this morning. <br />Under Task Ola, Pump down pit to establish slopes, you calculated the amount of <br />water that would need to be pumped from the pit based on a 23.92 acre pit when in <br />actuality, the size of the pit water azea for the worst case reclamation scenario will <br />be 12 acres. Dewatering a 12 acre pit to a depth of 18 feet would require pumping <br />approximately 70,379,021 gallons. Using your cost of $0.000176/gallon, the total <br />cost to dewater the pit to establish slopes can be calculated to be $12,387. <br />Under Task 02a, Cut west bankslope to 3:1 slope, you calculated the volume of <br />material to be moved as 28,747 loose cubic yards. Using a balanced cut and fill <br />method as shown on the attached figure, I calculate the volume of material needed <br />to be moved to create a 3:1 slope to be approximately 2,933 loose cubic yazds. Thi<, <br />calculation was obtained bymultiplying across-sectional azea of ] Ol square feet by <br />a distance of 700 feet, converting to cubic yards then multiplying by a swell factor <br />of 1.12, which you used in your calculations. Using your cost of $0.313 per loose <br />cubic yards, the total cost to grade the west bank slope to a 3:1 slope can be <br />calculated to be $918. <br />3. Under Task 06a, Topsoil replacement on 16.3 acres, you calculated a cost of <br />$34,509 to replace 18" of topsoil over 16.3 acres. The reclamation plan states that <br />topsoil will be replaced to a depth of 12" to 18". We request that the Division <br />consider accepting the replacement of 15" of topsoil, which we believe is the <br />average amount of topsoil that currently exists on the site. With respect to acreage, <br />the attached Map C-2 depicts the worst case reclamation scenario. In the worst case <br />
