Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in <br /> segregated piles at the edge of the active mine phase. Excavators,front-end loaders, and <br /> bulldozers will be used to excavate the material. Haul trucks and conveyors will be utilized to <br /> transport the raw material from the active mine phase to the processing area. See Exhibit C-5 <br /> for a cross-section of side-slope mining;after recovering to near-vertical at an offset or 3:1 <br /> setback to the planned top-of-slope, overburden, recovered silt or other suitable fill will be <br /> replaced to establish the final slope profile. <br /> (c) All water diversions and impoundments; <br /> Storm water will be discharged per a CDPHE discharge permit. There are no planned <br /> diversions or impoundments of existing water bodies. A wash cycle for the aggregate <br /> processing area will be established using the freshwater pond as a source and the silt pond for <br /> return flow,with a pipe between the source pond and the return pond. Any water consumed <br /> will be provided by the existing water rights associated with the property and/or a groundwater <br /> well with associated substitute water supply plan (see Exhibit G). <br /> (d) The size of area(s) to be worked at any one time. <br /> Each phase is approximately 27-97 acres in size. The Operator may mine multiple phases <br /> concurrently in order to obtain a range of material for production. In addition to mining,the <br /> Operator,will begin reclaiming slopes as mining is finished in each stage. Since multiple <br /> phases will be being worked at any one time, the approximate size of the areas to be worked <br /> at any one time will range from 25 acres to 120 acres and will depend on market conditions. <br /> (e) An approximate timetable to describe the mining operation. The timetable is for the <br /> purpose of establishing the relationship between mining and reclamation during the <br /> different phases of a mining operation. <br /> The Operator anticipates that mining will commence as soon as all permits are in place. The <br /> Operator anticipates extracting approximately 750,000 tons of aggregate in a typical year, up <br /> to 1,000,000 tons at peak capacity. Production rate will vary based on market demands. <br /> Monarch DENM—Gravel Mine—MLRB 112 Permit Amendment <br /> Exhibit D-2 <br />
