6.1.2 Mining <br /> The sand and gravel deposit will be mined to bedrock. An excavator stationed on a <br /> moveable platform will be used to mine the material wet. The mining excavations will not <br /> be dewatered. The mining will be done in three Cells ranging in size from 11 to 36 acres, <br /> with excavation conducted to bedrock. A previous geotechnical report (C.E. Maguire <br /> Subsoil Exploration Report, 1978) and the recently installed groundwater monitoring wells <br /> have established the bedrock surface at approximately 28 to 30 feet below ground surface. <br /> Wet mining will be completed from a long-reach excavator stationed on a movable 16'x20' <br /> (minimum)platform. Because the material is mined"wet",mined slopes will be no steeper <br /> than 2H:IV, consistent with slope stability calculations provided in Appendix B 1. <br /> The operator will develop and comply with a Stormwater Management Plan (SWMP). <br /> Berms and sloping of ditches will divert flow from all disturbed areas back into the mined <br /> cells. The operator will notify the Division of Mine Safety and Reclamation (DRMS) in <br /> the event of a reportable spill. <br /> Mined material will be stockpiled adjacent to the mining cells. The material will remain <br /> adjacent to the mining cell and drainage water will flow back to the mined cell. The <br /> material then will be loaded into haul trucks and transported offsite. <br /> 6.1.3 Imported Material <br /> Currently there are no plans to import material from other sites. Loveland Ready-Mix <br /> Concrete, Inc. (LRM) is aware that in accordance with Rule 3.1.5(9) of the Construction <br /> Materials Rules and Regulations,if any offsite material is used as backfill,a notarized letter <br /> will be submitted to the DRMS indicating the materials are inert. <br /> 6.2 Earthmoving <br /> Section 6.2 provides the information required by Sub-section 6.4.4(b) of the Rules and <br /> Regulations. <br /> Loveland Ready-Mix,Concrete,Inc. 7 September 2021 <br /> updared_erhihns_d_220415 do- T E L E S T <br />
