MINING PLAN (coNT) EXHIBIT C <br />removed and pushed to the processing plant on the mine floor. <br />When overburden/topsoil is encountered it will be stripped <br />and stockpiled around the perimeter of the site or on the benches <br />and floor for use in reclamation. An average of 1-2 inches of <br />salvaged overburden/topsoil will be placed on the mined area. <br />There will be some fines generated by processing that will be <br />salvaged to supplement the salvaged growth medium material. If <br />the overburden/topsoil stockpiles remain undisturbed for more <br />than one growing season a cover crop of Crested Wheatgrass will <br />be planted at a rate of 3.0 lbs pls/200 Ft2. <br />Of the 9.99 acres ± in the permit area, approximately 8.67 <br />acres ± will be mined, 0.10 acres will be road and 1.22 acres ± <br />will be setbacks around the mined area. The setbacks shown on <br />the Mining Plan Map is 20 feet wide except where the pit road <br />crosses the permit boundary. The material will be used to supple <br />road maintenance and construction products needed on County and <br />Forest Service roads in the vicinity of the mine. Once reclama- <br />tion is complete the area will be reseeded per the USFS require- <br />ments. The final intended end use is as rangeland. <br />The sand and gravel will be excavated using frontend load- <br />ers, trackhoes and dozers. The mined material from the working <br />face will be loaded into the processing plant with a frontend <br />loader . The RECLAMATION MAP - E-2 shows how the area will look when. <br />mining ends. On-site equipment may include, but is not limited <br />to, a motor grader, front-end loaders, motor scrapers, a dozer, <br />conveyors, a screening plant, dump trucks and a water truck. <br />Processing will be done on site to build material stockpiles <br />that will be removed as needed. This will create large stock- <br />piles of specification aggregates on the site as mining pro- <br />gresses. Once there is an adequate supply, the processing plant <br />will be moved to another site and the processed material will be <br />removed as needed. The mine will operate from March 1 to Novem- <br />ber 15 with periods of inactivity when adverse weather conditions <br />exist or there is no demand for material. During most years this <br />is the only time the mine is accessible due deep snow. No <br />estimate can be made on how long these periods of inactivity will <br />be, but some may last up to 6 months or more. <br />The bond estimate presented on Page 10 shows the amount of <br />land that will be disturbed as a worse case scenario. The <br />benches will be reclaimed as they are created and no additional <br />7 (revised 4/10/08) <br />-- - - --- i <br />
