EXHIBIT D - Minin¢ Plan <br />(a) Description ot'the method (s} of mining to be employed in each stage of the operation as <br />related io any surface disturbance on affected lands; <br />Access to the site will be off Huerfano County Road 613. A site access road with a double span <br />steel lockable gate already exists from previous permits at the northeast corner of the proposed <br />azea of opemtions. This access will be utilized for the duration of the mining activities. A total of <br />250 acres is within the proposed permit area of which approximately 200 acres will be ultimately <br />disnicbeil by mining activities. The uirdisluibeii areas (apprbXiinateYy 50+ acres) will consist of <br />perimeter buffer areas where some topsoil will be stockpiled and previously mined areas located in <br />the Phase ]Area. Barb wire fences emrenTly exist on the western and portions of the northern <br />eastern and southern sides of the site. Another barb wire fence/electric fence is installed east to <br />west across the site and around the current Hoskins Company pemut areas: Fences; gates and <br />access roads will be maintained as necessary during the life of operations at this site. Electric <br />fencing will be used to screen-off reclaimed areas as site phased operations progress through the <br />years. <br />Mining will be coridiiCted bn a "Phase' basis as shown Un the Exhibit C -Mining Pleti Map. A <br />total of seven (7) "Phase Areas" are planned to mine the 200 maximum planned mine acres. <br />Mining will be done, in the number ordered, however mine phase 4 and 5 may be switched in order <br />depending on site conditions at that future time. An amendment to the permit area maybe <br />considered in the futtu a which would be done to add to the permit any un-mined areas currently <br />lying within the Hoskins Permit Areas. <br />The Phase I Areas is 60 acres. Approximately 30 acres of the 60 acres in the Phase 1 azea will be <br />excavated and/or re-graded as part of the Phase 1 activities. Some of the spoil ntatetial in the <br />northeast and north end of the site will be graded to provide an elevated visual buffer/berm similar <br />to and matching the berm to the west separating the County Road from the area boundary. The <br />constructed berm will be seeded for stabilization with the recommended seed mu. These piles and <br />un-mined areas aze shown on the air photo attached to Exhibit B. <br />The applicant will use approximately 5 acres of the Phase ]area for site operations through all mining <br />phases. This area is indicated on the Exhibit C -Mining Plan Map. The planned 5 acre operations area is <br />located in the previous Western-Mobile permit area where reject material has been used to backfili a large <br />depression located in the previously mined areas. This 5 acre operations area will be the last remaining area <br />to be reclaimed after al[ mining phases have been completed. The large depression wilt be similarly used <br />and backfilled, as directed and desired by the landowner, using future process reject and overburden <br />material. <br />Lh the Phase 1 area, reclamation will be concurrent with area re-grading, removal of spoil and <br />mining the un-mined pockets. The overburden material in the Phase I Area ranges in thickness from 0 to <br />6 feet, Topsoil (surface material) is thin due to the Shamber gravel outcmp and the previous mining <br />operations in the north end of the proposed permit area. Anv and all available remaining topsoil (surface <br />material) will be reserved for reclamation. Most ofthis area has been mined previously under other permits <br />and has been inditYerentiy mined and reclaimed. l1h-processed aggregate spoil piles along with process <br />reject material and un-mined pockeu remain in this area and reclamation is incomplete and 'irregular. The <br />processing, removal and general re-grading of the waste spoil and un-mined aggregate material will provide <br />amore uniform reclamation across the old permit areas. <br />Phase 1 activities will clean-up, crush, screen and process out the remnant aggregate left by previous <br />mining operations/permits. Un-mined pockets will then be removed and processed. After reserving <br />any and alt topsoil the overburden material, when present and covering the u~r-mined pockets wil! be placed <br />in topographic low azeas th the Phase 1 area to level-out and normalize the slope across the disturbed area. <br />The reserved tapsoii will be placed and spread across the baskfiliedand re-graded surfaces prior to seeding <br />ASAP. <br />
