Background <br />1 The purpose of this application is to obtain authorization for Northern Colorado Constntctors Inc. <br />-Aggregate Division (NCCI) to mine, process and sell sand and gravel and to operate a concrete <br />1 batch plant on property owned by NCCI. NCCI will mine approximately 73 acres of the 102 acre <br />parcel located at the northwest comer of the intersection of Weld Coun[y Roads 18 and 25.Please <br />see the attached index map (Exhibit B) for the specific location of the area to be mined. <br />1 B. Operarional Methods <br />1 a. Description of mining method: <br />The applicant will begin mining on the north side of the mining azea and proceed <br />1 through the site in phases as shown on the Mining Plan Map. Upon completion of <br />mining Phase I, the site will be mined from north to south with the processing area <br />being at original surface until there is enough space in the pit to move the operation <br />I into the pit. Atypical section will be about 10 acres in size. Only one section or <br />portions of two sections and the processing area will be disturbed during any phase of <br />mining. This will minimize the amount of land disturbed at any one time. Please <br />' refer to the Mining Plan Map for details on the phasing order. <br />Site preparation <br />' Initial disturbance of the property will include removal of topsoil from the first phase, <br />establishing a processing area and dewatering. <br />1 Proposed Mining Process for Each Section <br />' Before any mining commences, the operator will install a dewatering trench azound <br />the section to be mined. This water will be pumped and discharged into a pond on the <br />property or into a ditch which discharges to the Platte River pursuant to a discharge <br />1 permit from the Colorado Department of Public Ilealth and the Environment <br />(CDPHE). The site will comply with all CDPHE regulations including monitoring <br />and reporting requirements for the life of the mine. <br />' After the section is dewatered, loaders and trucks will strip the topsoil and stockpile <br />it. The overburden will ultimately be used in reclaiming and sloping the shore. When <br />the alluvium is sufficiently dry, an excavator will place the gravel on conveyors or <br />NCCI1Llining Proposal jor the NCC! Pi! # 1- MLRB !
