on market conditions. It will take approximately three years to mine and two years to reclaim <br />it. <br />g. The depth and thickness of the mineral deposit to be mined and the thickness of <br />overburden to be removed. <br />Based on soils boring information, the topsoil and overburden is estimated to range in depth <br />of approximately 6 inches to 6 feet thick. The sand and gravel resource is an alluvial deposit <br />that ranges in thickness from approximately 20 to 40 feet, averaging approximately 30 feet. <br />Refer to Exhibit I of the Division of Minerals and Geology 112 Reclamation Permit application <br />for the boring information. <br />h. The proposed use of reclaimed lands and an explanation of the reclamation process. <br />Per the landowners' request, the Parker property (Phases 1 and 2) will be backfilled to create <br />pastureland. Please refer to the Reclamation Plan map for the proposed seed mix that was <br />developed in consultation with the Soil Conservation District. The former Dersham property <br />(Phase 3) will be reclaimed to a slurry wall lined water storage reservoir, due to the high <br />demand for water storage facilities along the Front Range. <br />As the excavation progresses, the operator will backfill previously mined areas. The <br />reservoir will be created with overburden material by using front-end loaders, bulldozers, <br />compactors and similar equipment. Final grading will create a topography that is appropriate <br />for the final land uses. There will be a maximum 3:1 side slope for the reservoir. The final <br />grading for the pasture will be similar to the existing pre-mining grades in the area. <br />Backfilling and grading will be completed as soon as feasible after the mining process has <br />been completed. <br />In the areas where revegetation is a part of the reclamation plan, the land shall be <br />revegetated in a manner that establishes a diverse, effective and long-lasting vegetative <br />cover that is capable of self-regeneration without continued dependence on irrigation or <br />fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding <br />area. Please refer to the Reclamation Plan Map and the Landscaping Plan Map for the <br />proposed seed mix and plantings and additional information about the reclamation plan. <br />Please also refer to Exhibit E -Reclamation Plan of the DMG 112 Reclamation Permit <br />application for further details. <br />i. The source of technical advice in that type of reclamation for open cut mining land. <br />Hall-Irwin Corporation has significant experience in both creating water storage reservoirs <br />and pastureland. The are currently operating numerous mining operations throughout the <br />Front Range, including the Firestien Resource (USR 1125), Baseline Resource (USR 1172), <br />LaPoudre Resource (USR 00571), Centennial Resource (permitted through the Town of <br />Milliken), Jo Dee Resource, and the Herbst Resource, which received a reclamation award <br />from the Division of Minerals and Geology. They will work with civil engineers to design and <br />construct the slurry wall, which must be bonded and approved by the Division of Minerals <br />and Geology prior to construction.
