<br />WECC will use fill material from the area known as the Bear Spoil <br />Stockpile and a small amount of shale and sandstone from <br />construction of overcasts to construct the foundation for the shop <br />and parking pad. No combustible, acid forming or toxic materials <br />will be used to construct the foundation. <br />A cross-section of the pile is shown on Attachment C. The <br />foundation will be constructed as described for the initial waste <br />rock pile in Exhibit s".2.9.A.1 as approved by the CMLRD except that <br />the outslopes of the foundation will. be covered with 18 inches of <br />topsoil prior to seeding with the permanent seed mix described in <br />Table 4.4.5.A of the Mt. Gunnison h1&R Plan. The foundation material <br />will be spread in uniform layers not more than 24 inches in loose <br />thickness and then compacted to at least 90% of the maximum density <br />as determined by the AASHTO T99-74 or equivalent test method. The <br />foundation will be sloped to a 1% grade to the east, as shown in <br />Attachment B, to drain to the existing shotcrete drainage ditch. <br />Upon completion of the foundation, a 175' x 55' shop expansion will <br />be constructed and the remaining area covered with asphalt and used <br />for parking. <br />Final reclamation of the disposal site will be in accordance with <br />Section 4.4 of the Mt. Gunnison Mining and Reclamation Plan. <br />Consistent with reclamation bond calculations for the surface <br />facilities area, cost for demolition of the new shop was determined <br />based upon construction costs. <br />Anticipated construction costs = 51.2 h1M <br />Labor portion: 30% of construction costs = 50.36 hU1 <br />Demolition: 15% of labor costs = 50.054 t4M <br />Removal of asphalt pad = 50.005 MM <br />TOTAL BOND FOR DEMOLITION OF PAD AND BUILDING = 50.059 Mhl <br />Revegetation costs for this site were included in the 80 acres <br />rangeland (surface facilities) revegetation cost calculations shown <br />in Table 4.8.1.A of the Mt. Gunnison M and R Plan. Thus additional <br />bond for this activity = 559,000. Current reclamation costs for Mt. <br />Gunnison presently total 51,952,513. Current bond for the Mt. <br />Gunnison Mine = 52,702,700. Thus there is sufficient bond to cover <br />this activity. <br />Sincerely, <br />~ __~ <br />' ~-~r <br />Paige~Fs'.
