reservoir and the reclamation slope will be constructed using the excess overburden to a 4.5H:1 V <br /> slope. The processed aggregate material will be temporarily stockpiled near the portable <br /> processing plant. <br /> Recommendations for monitoring of slope stability, including, conducting a visual inspection of <br /> the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection <br /> after a major precipitation event that has saturated the ground using the same procedures, <br /> contacting qualified personnel to evaluate and recommend remediation work to stabilize the area <br /> in the event a visual inspection detects signs of potential slope failure, and if no visible signs of <br /> slope failures are detected during mining, reducing visual inspections to once every six months <br /> after mining completion, or after every major precipitation event. <br /> All local, State, and Federal rules and regulations will be followed for the storage and handling of <br /> 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 for all the mining phases is approximately 13,000 <br /> cubic yards. The depth of the topsoil is approximately six inches over the majority of the mining <br /> area. The topsoil will be stripped and stockpiled during each phase of mining where topsoil will <br /> only be removed for Phase 1 as Phase 1 is mined. Mining will start from the northeast corner then <br /> moving south approximately to one third of the property then west, then moving south to another <br /> third of the property back to the east, then moving south to the final third of the property to the <br /> west to complete mining and reclamation. The height of the topsoil stockpile will be approximately <br /> 15 feet to 20 feet. <br /> Mine Phasinq <br /> IHC Scott, Inc. anticipates mining and reclaiming the Bernhardt Sand and Gravel Pit in 1 phase, <br /> progressing through this phase as shown on the Mining Plan Map. The overall time required to <br /> complete the mining and reclamation is estimated to be 11 years based on an average rate of <br /> 650,000 tons per year. The initial production is expected to be 300,00 tons per year with the <br /> maximum production expected to be 1,000,000 tons per year. However, it is possible that due to <br /> demand fluctuations, mining could progress slower than anticipated and additional time may be <br /> required for mining and reclamation of the site. <br /> Phase 1 is 98.24 acres and the estimated time for mining Phase 1 is approximately 11 years. <br /> The mining will progress beginning at the outer edge of the phase where material will be moved <br /> toward the interior of the phase such that the mining slope can be established. The mining slope <br /> will be established for the entire perimeter of the phase in 3 to 6 feet intervals. <br /> Dewatering <br /> Dewatering trenches will be placed along the perimeter of Phase 1.The dewatering trench around <br /> the perimeter of the phase being mined will be placed at the toe of the mining slope.As the phase <br /> is mined deeper the dewatering trench will be lowered and moved laterally along the mining slope <br /> toward the center of that phase. A slurry wall is anticipated to be installed around the perimeter <br /> of Phase 1 prior to exposing groundwater and mining will continue to commence and it is expected <br /> minimal dewatering will be required after the slurry wall is installed due to the slurry wall cutting <br /> IHC Scott,Inc. <br /> J&T Consulting,Inc.
