f) Deposit <br />Development activities will include pre- stripping of the gravel zone, processing site construction <br />and establishment of crushed and screened material stockpiles. <br />Pre - stripping activities will provide material for construction of a 30 foot wide access road from <br />Weld County Road 99 into the processing area as well as a 24 foot wide, 5% grade haul road from <br />the processing area into the mining zone. The processing area will contain a crusher, screening <br />and staking machine or machines, a truck scale and an office trailer for a site attendant. A 3 wire <br />barb wire fence will be erected for cattle and wild life protection. <br />A water quality feature and diversion swales and berms will also be established. <br />3. Operations <br />Operations consist of normal stripping and mining of the gravel deposit and reclamation of the <br />spoil overburden that has been placed in the final deposit zone. <br />Normally, the seasonal stripping and mining operation would be scheduled for approximately <br />three summer months. The actual schedule would be dictated by material sales. For the purpose <br />of this discussion, 100,000 tons of within - specification material sales shall be used to dictate <br />duration of operations throughout the summer months. <br />The approximately three month long mining operations would consist of dozer operations plus <br />truck loader transport of spoils to spoil stockpiles and gravel to the processing area for screening <br />and crushing. No high wall mining will be used. Cut slopes will normally be % horizontal to 1 <br />vertical. Spoil slopes will be no steeper than 3 horizontal to 1 vertical. The processed material <br />would be stockpiled by stacking conveyors to select stockpiles. A water truck would be used for <br />dust control. <br />It is anticipated that the 3 months of operations would develop stockpiled material that would be <br />sufficient for ongoing sales throughout the off mining months. <br />4. Reclamation <br />Reclamation activities would continue normally after the mining months into the late fall. No <br />operations other than sales would occur during the winter months. <br />The gravel pay zone occurs in a calcareous gravelly alluvium and is generally 9 to 11 feet in thickness. The <br />overburden consists of silty sandy loess that varies in thickness over the area. The gravel beds lie on top of <br />a weathered sandstone formation. It is estimated that approximately 800,000 to 1,000,000 tons of <br />recoverable gravel occur in the area of consideration. <br />g) No other primary or secondary commodities are to be mined or extracted. <br />3 <br />
