(b) Earthmoving Sand and gravel will be excavated by front-end loader and loaded into haul trucks or onto conveyors and transported to the processing area. (c) All water diversions and impoundments The perimeter of the mined azea will be dewatered by digging a trench to bedrock. The water will be pumped into a settling pond and discharged into the Big Thompson River or broadcast on the trees to be preserved in the Big Thompson riparian cottonwood gallery. Wash water for the processing area will be recycled through a series of small ponds within the processing azea. All water required to operate the facility will be provided by the existing water rights associated with the property. No ditches will be disturbed without prior authorization of the appropriate ditch company. (d) The size of area to be worked at any one time Excluding the processing area, a maximum of 32 acres will be disturbed by mining at any one time. (e) An approximate timetable to describe the mining operation. The timetable is to establish the relationship between mining and reclamation during the different phases of mining The applicant anticipates that mining will commence as soon as the permits are in place. The gravel deposit on this site is estimated at 11.4 million tons. It will take approximately 25 years to mine and reclaim this property. Annual production is estimated to be 800,000 tons. This may vary depending upon the demand for construction material and may impact the total life of the mining operation. The property will be mined in five phases (see Mining Plan Map for phasing). Refer to Exhibit E for the mining and reclamation schedule. (n Use Mining Plan Map in conjunction with narrative to present: (i) Nature, depth and thickness of the deposit and thickness and type of overburden Hall-Irwin drilled the site. The test holes are shown on the Existing Conditions map. ,Please refer to Exhibit I -Soils Information for a copy of the drill togs and details about the deposit. (ii) Nature of the stratum immediately beneath the material to be mined in sedimentary deposits According to the "Geologic Map of the Boulder-Ft. Collins-Greeley Area, Colorado" published in 1978 by the U.S.G.S., Map I-855-6, regional geologic mapping indicates the bedrock underlying the alluvial sand and gravel is most likely the Fox Hills Sandstone. The Fox Hills Sandstone is approximately 300 to 500 feet thick in the project area. The Upper Transition Member of the Pierre Shale is also mapped nearby and may underlie parts of the site. The Upper Transition Member of the Pierre Shale is approximately 2,000 feet thick in this area. Hall-Irwin Corporation Bernhard[ Resource Page 13 of 41 MLRB 112 Permit Application
