C Page 12-6d of Tab 12 has been revised to reflect the production of a • <br />contour map annually by a professional firm qualified t.o perform the <br />work and to submit a copy of the snap to the Division. <br />COF11+lEIJT: <br />6. 8ackfilling and Grading/Reclamation Costs <br />A. 4;adge West Pit/Auger Area E/Solid 4laste Disposal Area <br />based on a review of a current aerial photograph (Exhibit 12-2) of <br />the Seneca II mining operation, it appears that a substantial <br />disturbance remains in the above-referenced area, presumably <br />consisting of the final SJadge west pit, pit highwall, associated <br />ungraded spoil material generated by the final excavation, and the <br />portion of the pit currently being used as a solid waste disposal <br />area. Also, apparent from the aerial photograph is the presence of <br />a large disturbed area situated west of the pit highwall, most <br />li4•.ely an area of exposed overburden from which topsoil has been <br />stripped. What is unclear from either the aerial photograph, <br />C Operation Plan Map, or information provided in the revised text, is • <br />the current disposition of what should be the existence of two <br />series of box cut spoil piles, one being generated by the initial <br />excavation of the Wadge west pit and the second being generated by <br />the creation of the Wadge east pit. Page 12-53 of the revised <br />permit renewal application states that "The box cut material from <br />the initial Wadge pit has been graded into the surrounding <br />terrain". ]t is unclear as to whether this statement pertains to <br />box cut spoils from the 4ladge east pit, Wadge west pit, or both. <br />A further review of Exhibit 12-2, Facilities Map, in the area where <br />the solid waste disposal site is located, appears to show a fairly <br />substantial disturbance within acrd adjacent to the disposal area, <br />presumably consisting of the disposal pit, surrounding ungraded <br />spoil material, and areas of exposed overburden from which topsoil <br />has been stripped. This area appears to he much greater in size <br />than the one acre figure used on Page 13-57 for calculating grading <br />costs. • <br />28 <br />
