Banks and Gesso, LLC <br />Sand and Gravel <br />Nominal thickness of sand and gravel on the site is 25 feet. This will amount to a total <br />reserve of approximately 12 million cubic yards. About 10% of the sand and gravel <br />deposit will be process waste (approximately 1.2 million cubic yards). This material will <br />also be used for reclamation backfill. <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 (i.e. pond) after <br />mining is completed. The access to Nyberg Road and one perimeter road around the <br />property will remain after mining and reclamation are completed. This permanent road <br />will be approximately 24 ft. wide and will be surfaced for all weather access (i.e. <br />graveled). <br />Drainage. Runoff and Dewaterina 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 will be obtained for the outfall structure, if required. <br />Sizino of Settling Ponds and Outfall Structures <br />Settling ponds and outfall structures will be engineered to meet the discharge <br />requirements. <br />St. Barbara Sand and Gravel Mine 03028 <br />Trans Colorado Concrete tp February 19, 2004 <br />
