EXHIBIT D <br />MINING PLAN <br />The information for this section is intended to satisfy the requirements outlined in Section <br />6.4.4 of the Colorado Mined Land Reclamation Board's Construction Material Rules and <br />Regulations. <br />A. Background <br />The purpose of this application is to obtain authorization for Hall-Irwin Corporation <br />(Hall-Irwin) to mine, process and sell sand and gravel, sell landscape materials, and <br />operate concrete, recycling and asphalt batch plants at the Water Resources, LLC <br />property. Hall-Irwin will mine approximately 89 acres of a ±134.21-acre parcel located <br />near Greeley, Colorado. Please see the attached Mining Plan Map for the specific <br />location of the area to be mined. <br />B. Operational Methods <br />a. Description of mining method: <br />The applicant will begin mining at the northeast side of the property and <br />proceed west through the site in phases to minimize the amount of land <br />disturbed at any one time. The site will basically be mined beginning on the <br />northern most half of the site mining phases 1 and 2 from west to east. Phases <br />3-6 are in the southern and western portions of the site and will be mined east to <br />west, starting at the point furthest from the processing area and working toward <br />it. Please refer to the Mining Plan Map for details on the phasing order. <br />Site preparation <br />Initial disturbance of the property will include: <br />• The slurry wall will be constructed around the perimeter of the mining area. <br />• The perimeter berms will be installed along Weld County Road (WCR) 58. <br />The applicant will plant grass along the berm to help screen the site and install a <br />split wood rail fence for visual interest. The berms are designed to allow <br />historic drainage and flood waters to pass through the site unobstructed. <br />• The area adjacent to the entrance will include signage for the facility. Once <br />mining is complete, the signage will be removed and the entrance will serve as <br />access to the water storage reservoirs. <br />• The overburden material from Phase 1 will be used to fill the necessary <br />structures in the processing area above the 100-year floodplain. <br />Proposed Mining Process for Each Section <br />Before any mining commences, the operator will install a dewatering trench <br />around the mining area. This water will be pumped into the existing <br />irrigation/drainage ditch located along the northern edge of the property. The <br />applicant will obtain a discharge permit from the Colorado Department of <br />Hall-Irwin Corporation Page 14 of 35 <br />MLRB 112 Permit Application <br />
