A combination <br />of pit-floor shale materials and excess topsoil will be utilized for reconstruction of <br />the pit slopes to 3:1 and 2:1 and the reconstructed Lupton Bottom Ditch <br />alignment. <br />Aggregate Processing <br />The pit-run sand and gravel will be screened, crushed and washed to remove <br />silt-sized material prior to off-site sales or for further onsite processing into <br />concrete or asphalt. The wash-water containing this silt will be directed to a <br />settling pond to permit settling-out of the silt. The clarified water will be recycled <br />to the plant for continued washing, with any make-up water being provided by the <br />alluvial well located at the south-central portion of the property and outside the <br />slurry wall. The proposed pond system that will be utilized to facilitate these <br />washing steps is to be located adjacent to the plant processing area and will <br />service not only the aggregate-processing needs, but also the asphalt and <br />concrete batch plants. All water used in the operation will be recycled, except for <br />water lost in evaporation or lost as part of the shipped final products. The only <br />water subject to periodic discharge to the South Platte River will be from mine <br />de-watering and from pit-floor stormwater runoff. The discharge point will be <br />Ft.
