EXHIBIT D—MINING PLAN <br /> a. The topsoil and overburden will be removed from any area currently <br /> being mined and stockpiled around the perimeter of the permitted area. <br /> b. The resource will be removed and transported to the processing area <br /> with front-end loaders. Material processing occurs on-site. As the resource <br /> is removed from the active mining area, it is transported to a processing area <br /> where it will be screened and crushed. Sized material is then loaded onto <br /> trucks for transport off-site, or taken to a wash plant for washing and further <br /> sizing. <br /> The excavation equipment that will be used at this site consists of front-end <br /> loaders, dozers,backhoes, graders, excavators and gravel trucks. Processing <br /> equipment at the site consists of jaw, 1 cone crushers and 1 screening plant <br /> with related conveyor belt systems to service the crushers,jaws and screen. <br /> The applicant would like the option to include a wash plant for future use if <br /> there is a need for washed products. The applicant has been approved by the <br /> Grand County Board of County Commissioners to include a portable asphalt <br /> batch plant/and or portable concrete plant at a later date. This approval is <br /> part of the Special Use Permit that was approved on February 1, 2022. <br /> C. This is a dry mining operation as groundwater is believed to be <br /> approximately 60 to 75 feet below the surface. This operation will not <br /> expose groundwater during the mining of the site. <br /> If a wash plant is used at some time during the operation the settling pond at <br /> the site will be used only for water discharged from the wash plant. <br /> Groundwater will not seep into the settling pond. The water and material <br /> discharged from the wash plant will be allowed to settle out the fines, then <br /> reused to wash materials. A small amount of water may seep back into the <br /> ground. <br /> No earthen dams used to impound water will be constructed at this site. <br /> d. The area of disturbance from the original permit is approximately 15 <br /> acres that was divided into Phase I and Phase H. It was originally thought <br /> that mining would be done to a depth of 40 feet in each phase however, as <br /> mining progressed it was determined that mining could go as deep as 55 feet <br />
