<br />MINING PLAN <br /> <br />EXHIBIT "D" <br />(A) Description of the methods of mining in each stage of operations related to a surface <br />disturbance: <br />Mining methods will be consistent throughout the life of the mining operation. The topsoil or <br />growth media will be salvaged and stockpiled on the pit perimeters in an orderly berm suitable for <br />seeding in the event that it is to remain for more than one growing season. The stockpiles and berms <br />will be placed in the most strategic locations for replacement in reclamation. The aggregate will be <br />removed primarily by front-end loader for transport to a screening or crushing and screening system <br />(probably on site) for processing into the desired products as business demand dictates and then <br />stockpiled for future use. According to the SCS report for Cascajo soil series which constitutes the <br />aggregate azea, the topsoil or growth media ranges from 4" - 8". Topsoil is a misnomer for this soil <br />type, since it is described as a very gravelly sand loam with 60% cobbles. Over the years some <br />humus has been built up in the top 4" - 8" which helps in revegetation. The pit floor will daylight <br />to the contours on the pit perimeters where possible which will actually be most of the area. This <br />operation consists of removing the tops of knolls with the final surface left flat. <br />(B} Earthmoving:: <br />.The earth moving equipment to be used on this site will consist primazily of front-end wheeled <br />loaders, dozers, self propelled scrapers or any combination thereof. <br />There will be "no mining" area buffer undisturbed of 50' minimum on either side of the center line <br />of the power line that crosses the NE1/4 NW 1/4 of Section 22, T21 S, R64W from the northwest to <br />the southeast. <br />(C) Water diversions and impoundments: <br />There will be no water diversions or impoundments on site since no water will be used for this <br />operation and none is available. The operator is applying for a Colorado Water Quality Control <br />Division Stormwater Dischazge Permit concurrently with the development of this application. <br />(D) Size of the area to be n•orked at any one time: <br />Present plans aze to affect a maximum of 30 acres at any one time. The first azea will be that portion <br />of the NE1/4 NW 1/4 Section 22, south of St. Chazles Road. When that area is mined out, the <br />operation will then move west and south to those portions of the SW 1/4 NW]/4 Section 22, After <br />this is mined out, the operation will continue to the permitted area in the SE1/4, Section 21. <br />D-1 <br />
