EXHIBIT D <br />MINING PLAN <br />Tri -River recently transferred the existing 110(c) permit for the Yust Ranch Gravel Pit to Grand Gravel <br />Pit, LLC. Grand Gravel Pit, LLC would like to expand the existing operational footprint to 41 acres from <br />9.9 acres and is therefore requesting a 112 permit. <br />The removal of gravel deposits from the permitted area will begin at the west side of the existing pit <br />face (permitted by the 110(c)) moving west and north at a depth of 15 -20 feet. The excavation and <br />removal of this material will require a front -end loader and possibly a conveyor. The phasing will be <br />market driven and will progress from east to west as shown in Exhibit C. We anticipate mining and /or <br />processing up to 100,000 tons per year with the life of the reserve estimated at approximately 20 -25 <br />years. <br />Equipment required for this operation will include: <br />• Crushers • Stackers <br />• Screens • Loaders <br />• Feeders • Bulldozers <br />• Conveyors <br />Mining operations will not encounter groundwater as it will stay at or above the level of the adjacent <br />pit. The majority of the existing haul road will be utilized for travel to, through and from the pit. One <br />portion of the road will be mined and the alternate route is as proposed on the Mining Map in Exhibit C. <br />Topsoil will be stripped at an average depth of approximately 4 -6" and stockpiled on the northwest side <br />of the permit area for reclamation. The stockpiles will be seeded to prevent erosion as described in the <br />soil conservation report. <br />Stormwater will be contained within the pit area using the backsloping grade directed at the back wall. <br />YUST RANCH GRAVEL PIT <br />112 CONVERSION APPLICATION <br />M 2000 -014 Page 4 <br />
