Paul Banks and Associates, LLC <br />sand and gravel deposit will be process waste (approximately 1.2 million cubic yards). <br />This material will also be used for reclamation backfill in the northern part of the <br />property. <br />Operation Components <br />The access to a public road (i.e. Nyberg Road), mine boundaries, office /scale house, <br />and processing plant are shown on Exhibit C -3. <br />Roads <br />All roads inside the mining limits will be temporary and will be reclaimed after mining is <br />completed. The access to Nyberg Road and one perimeter road around the property will <br />remain after mining and reclamation are completed. <br />Drainage, Runoff, and Dewaterinq Conveyance Structures <br />Storm drainage will be either 1) routed into the pit floor and used for processing water or <br />discharged through the dewatering system, or 2) routed to the settling pond in the <br />southeast part of mining area 1. Diversion ditches and berms will be used, if necessary, <br />to ensure that runoff from disturbed areas will be controlled in this manner. <br />Dewatering water will be conveyed from a dewatering trench to a settling pond. From <br />the settling pond the water will be discharged through an outfall structure into the <br />Arkansas River pursuant to an approved CDPS permit. A U.S. Army Corps of Engineers <br />permit has been obtained for the outfall structure. <br />Sizing of Settling Ponds and Outfall Structures <br />Settling ponds and outfall structures have been designed to meet the discharge <br />requirements. <br />Water Demand and Source <br />Exhibit G, Water Information, contains a discussion of water demand and source. Also <br />contained in Exhibit G are discussions of protecting the hydrologic balance (groundwater <br />and surface water) and compliance with Colorado water law. <br />St. Barbara Sand and Gravel Mine 10031 <br />Pete Lien & Sons, Inc. 10 June 15, 2011 <br />
