NEWMONT <br />GOLDCORR <br />Growth medium is stored to depths and slopes appropriate for access for placement and removal, <br />erosional stability, and minimization of the footprint to limit additional disturbed area. Growth <br />medium storage areas, when in place for more than one year and with no further development at <br />the storage areas planned, are seeded with the same or a similar seed mix approved by DRMS <br />for use in reclamation (see Reclamation Plan provided in Exhibit E). The seed mix may emphasize <br />annuals if the storage area is anticipated to be moved within approximately two years (see Table <br />J-1 and Exhibit J). <br />If necessary, erosion control structures, run-on diversion ditches, or equivalent structures <br />designed for two times the 10 -year, 24-hour precipitation event will be constructed up -gradient of <br />growth medium areas for protection. A more complete discussion of water and sediment control <br />from stormwater runoff is contained in Exhibit U. <br />3.2 Mining Areas, Operations, and Equipment <br />Surface mining and backfilling will continue in the previously approved areas, predominantly in <br />North Cresson Mine area, and East Cresson Mine area. Each mine area is shown on Drawing C - <br />4a. <br />Surface mining will continue to use conventional mining excavation methods as presently being <br />conducted at the Cresson Project. Overburden and ore will be mined using conventional <br />production blasting, loaded into haul trucks with hydraulic shovels or front-end loaders, and <br />hauled to the appropriate location. The mine areas will be developed by constructing a series of <br />benches. The height and the width of the benches will vary depending on the local geology, <br />stability of the wall material, and mining needs. <br />Table D-5 presents the anticipated equipment list for surface mining activities. <br />Table <br />Equipment. <br />Drills <br />D-5: Anticipated Equipment List <br />Rotary/percussion with 6.75 -inch hole diameter / Smaller drill pre -split <br />Rubber Tire / Track Loaders <br />12 to 32 yds3 bucket capacity <br />Hydraulic Shovels <br />32 to 40 yds3 capacity <br />Haul Trucks <br />85 -ton and 240 -ton capacity <br />Dozers <br />Rubber Tire Dozers CAT 834 or equivalent or larger class <br />or CAT dozers of D9, D10, and D11 class <br />Track -hoes <br />Caterpillar or equivalent 235 or larger class <br />Water Trucks <br />13,000 and 20,000 capacity <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Amendment 13 <br />11 <br />Exhibit D <br />
