overburden may be used for backfilling if needed. Topsoil and overburden will be kept separate <br /> and not mixed and each type will be clearly identified in the field. <br /> The expanded operation will consist of three Phases,to include the existing mined pit. Phase <br /> One will be approximately 19.16 acres (which includes the original 9.84 acre 110 Permit), <br /> Phase Two, 15.62 acres and Phase Three, 13.21 acres. Each Phase will be mined separately. <br /> The total acres to be stripped of topsoil in any given year will be approximately 1/4 tol/3 of the <br /> proposed affected acres in each Phase. Worst case, the area being stripped and mined should <br /> not exceed about 5 acres. <br /> Mining will begin by finishing the excavation in the existing 110 pit area(Phase One) and then <br /> proceed to Phase Two. The last Phase to be mined will be Phase Three. By the time Phase <br /> Two is reached, two-thirds of Phase One should be under reclamation except for the overburden <br /> stockpile and the material process site, if kept in Phase One. <br /> (b) Earthmoving: <br /> Earth moving consists of first removing topsoil,then any overburden and finally aggregate. <br /> The resource lies beneath the topsoil to an estimated depth of from 10 to 17 feet or more feet. <br /> Once mining is nearing completion, the final slopes will be mined at a 3H:1 V slope. These <br /> slopes will then have topsoil replaced and the area seeded to the approved seed mix. <br /> (c) Water diversions and impoundment: <br /> No diversions are planned. <br /> There are several ephemeral drainages which drain to the north of the proposed expansion area. <br /> Internal mine access roads will cross these drainages. Appropriately sized culverts will be <br /> installed so as not to impede storm water runoff. No diversion or impoundments are planned. <br /> (d) The size of the area(s) to be worked at any one time: <br /> Total acres to be stripped in a given year will be up to approximately 1/4 to 1/3 of a phase. For <br /> example, the largest phase, Phase 1 (the area of the original 110 permit) could initially affect as <br /> much as 5 acres, dependent upon the Town of Limon needs. <br /> (e) An approximate timetable to describe the mining operation: <br /> This is an ongoing, intermittent mining operation. The expected life of the mining area is 25 to <br /> 50 years, depending on The Town of Limon needs. We estimate the amount of mineable acres <br /> by phase is as follows: <br /> 24 <br />
