C7 <br />MINING PLAN <br /> <br />a. This mine shall utilize the open cut method of mining. The mining <br />is ongoing, at this time, at the West end of the pit thru a con- <br />ditional use permit granted in 1975 by Rio Blanco County. This mining <br /> <br />shall continue from West to East at a rate dictated by markct dcmands <br />for the various aggregates produced. <br /> <br />b. Topsoil is scarce or absent altogether (see your report 1177-132 dated <br />November 17, 1977) at this site. We believe. however that the top 6 to <br />12 inches should be stripped and stockpiled for revegetation and reclamation. <br />• <br />~~ <br />~~ <br />~~ <br />I[: <br />I[7 <br />Overburden will be removed and stockpiled within areas where major <br />disturbance has occurred. These stockpiles will be moved from time <br />to time in order to facilitate additional mining within the area of <br />major disturbance. As the mining operation proceeds from West to East <br />and minerals are depleted the overburden will be utilized to bring <br />depleted areas to grade as shown in the reclamation plan. <br />Utilizing portable crushing and/or washing equipment, as the market <br />dictates, the aggregates will be crushed, graded and/or washed to produce <br />various aggregates and products to satisfy the demands of that market. <br />This will require stockpiles of various materials to be kept on hand <br />at all times. <br />c. See page S of Lease Agreement for water information. <br />d. Stockpiles as well as overburden piles will occupy space in the mining <br />area adjacent to the mining area currently being worked. The areas <br />occupied will only occur where major disturbance has already taken <br />place. As mining areas are depleted of mineral resources they will <br />be reclaimed utilizing overburden stockpile reserves. Therefore, major <br />~• <br />disturbance will only occur where active mining is ongoing. We antici- <br />pate that these areas of major disturbance will be 10 acres more or <br />less. <br />~~ <br />e. Current and future market demands dictate the life of the pit. As <br />stated earlier, the pit will be mined from West to East with no set <br />timetable. We anticipate the life of the pit to be approximately 25 <br />~ • <br />years. <br /> <br />
