historical volume of ditch water. <br />• Water pipelines: <br />Upon final reclamation, several buried water delivery pipelines will be constructed as <br />part of the developed water resource reclamation plan. Connecting buried water <br />pipelines will run from Phase One to Phase Two cell. A buried discharge water pipeline <br />will run from the Phase Two cell to the Arkansas River. <br />The buried pipelines will be installed in excavated trenches with appropriate bedding <br />materials, obtained from the sand and gravel extraction operation. Trenches and <br />placement of the waterlines will be accomplished using equipment suitable for such <br />construction, such a long reach backhoes, draglines, dozers, front -end loaders and <br />motor - graders. Upon completion of pipeline installation, all associated affected lands <br />will be reclaimed according to the approved reclamation plan. <br />(c) Water diversions and impoundment: <br />Crossing portions of the proposed mining area is the Excelsior Ditch. The Ditch is owned, maintained <br />and operated by Excelsior Ditch Company. The Applicant/Operator has agreements with the Excelsior <br />Ditch Company to relocate the ditch to the north of the proposed mining area as shown on Exhibit "C" <br />Mining Plan Map. The Excelsior Ditch diversion will be trapezoidal in shape, being approximately 15 <br />feet wide at the invert of the channel with 2 horizontal to 1 vertical side slopes. <br />Outside of relocating the Excelsior Ditch, no surface water features exist in the mining or processing <br />areas. Therefore, no other diversions or impoundments (other than the water storage structures, <br />emergency spillways and associated discharge conveyance structures) are planned. <br />A Stormwater Management Plan will be developed and implemented and a Stromwater Permit will be <br />obtained from the Water Quality Control Division, Department of Public Health and Environment, <br />State of Colorado prior to mining and construction activities. <br />The slurry walls and the zoned perimeter dam in Phase Two will be constructed in phases to mitigate <br />
