Box 246 <br />Wiley, CO 81092 <br />(719) 829-9350 <br />1.0 Site Description <br />The Mid-Western Farms Resource is located approximately two miles <br />west of Holly, Colorado in the Southwestern corner of the state. <br />This site sits north of the Arkansas River and South of U.S. <br />Highway 50. This will be a wet mined sand and gravel resource. <br />2.0 Description of Operation <br />This operation will be a wet mine with a clam shell dredge used to <br />excavate the material. No dewatering will occur at this site. <br />Drainage at the site is generally from northwest to southeast. <br />Sand and gravel mining will begin at the center point of the site <br />to the south of the railroad and will continue to the west first, <br />then towards the eastern side of the site. An asphalt plant and a <br />concrete batch plant will be set up in the processing area on the <br />north side of the railroad. All material processing will occur at <br />this processing site. <br />All stormwater runoff will flow across the disturbed areas and into <br />the excavated pits. A levee currently exists on the north side of <br />the Arkansas River that will prevent any and all stormwater runoff <br />from entering the river. <br />Some channelization may need to be added during future mining <br />phases in order to continue collecting all runoff in the excavated <br />areas. Any additional stormwater conveyance improvements will be <br />described in future annual SWMP reports if they are constructed. <br />Topsoil and overburden stockpile locations change to accommodate <br />the mining location, and therefore are not shown on the map. The <br />major axis of the stockpile layout shall be aligned with the <br />direction of potential flow in the floodplain. The stockpiles <br />shall be located as far from the Arkansas River as reasonable, to <br />reduce potential impedance of flood flows and sediment transport <br />impacts. The stockpiles shall not be allowed to cause the flood <br />elevations to rise, and therefore the amount of material stored at <br />the site will be minimized. <br />-1- <br />
