The 3H:1 V slope will continue to a depth 10 feet below the normal water surface elevation to an <br />elevation of 4581. The processed aggregate material will be temporarily stockpiled near the <br />portable processing plant which lies outside the floodplain. <br />All local, State, and Federal rules and regulations will be followed for the storage and handling <br />of any fuel for the facilities. <br />Topsoil Handling Plan <br />As stated previously the topsoil will be stripped to expose the aggregate product underlying the <br />topsoil. The topsoil will be stripped using scrapers and stockpiled in the topsoil stockpile as <br />depicted in Exhibit C. The volume of topsoil is approximately 113,000 cubic yards. The depth of <br />the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will <br />be stripped and stockpiled during Phase 1 - 11. The height of the topsoil stockpile will be <br />approximately 15 feet. <br />Mine Phasing <br />Journey Ventures, LLC anticipates mining and reclaiming the Journey Ventures Pit site in 11 <br />phases, progressing through the phases as shown on the Mining Plan Map. The overall time <br />required to complete the mining and reclamation is estimated to be 25 years. Maximum <br />production is expected to be 250,000 tons per year. However, it is possible that due to demand <br />fluctuations, mining could progress slower than anticipated and additional time may be required <br />for mining and reclamation of the site. Journey Ventures, LLC will mine to an elevation of 4594 <br />in Phase 1 - 2 of the mining plan encompassing a total of 12.61 acres of the mining limits and <br />groundwater will not be exposed. <br />It is expected that 2 phases will be disturbed at any given time, and if more are disturbed <br />Journey Ventures, LLC will provide notification to DRMS and financial warranty for each phase <br />prior to opening or disturbing. <br />The mining will progress in each phase beginning at the outer edge of the phase where material <br />will be moved toward the interior of the phase such that a 3H:1V mining slope can be <br />established on the exterior of the phase and then transition to a 2H:1V slope. The mining slope <br />will be established for the entire perimeter of the phase in 3 to 6 feet intervals. In Phases 3 - 11 <br />a dewatering trench around the perimeter will be placed at the toe of the 3H:1 V or 2H:1 V mining <br />slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally <br />along the 3H:1 V and then the 2H:1 V mining slope toward the center of that phase. Once the <br />interior footprint becomes small enough where the 2H:1 V mining slopes from three to four sides <br />are encroaching upon the portable plant and haul roads another phase will be opened to <br />continue mining. <br />In Phase 11 the mining operation will not mine down to bedrock but rather to an elevation of <br />4520. The slope stability study indicates that a factor of safety of 1.25 cannot be achieved for <br />the proposed mining slopes at a depth greater than the elevation of 4520. <br />Dewatering <br />Dewatering trenches will be placed along the perimeter of each mining area in Phases 3 - 11. <br />The dewatering trench around the perimeter of the phase being mined will be placed at the toe <br />of the 3H:1 V or 2H:1 V mining slope. As the phase is mined deeper the dewatering trench will be <br />lowered and moved laterally along the 3H:1 V or 2H:1 V mining slope toward the center of that <br />0 Journey Ventures, LLC. <br />.1sT Consulting, inc.
