by the West Divide Water Conservancy District (WDWCD). A copy of the approved supply <br />contract and well permit will be provided to the DRMS when it becomes available. <br />Pond(s) will be built within the permitted area of the quarry. The existing Belden Shale should <br />create an impermeable seal in the ponds to allow for recirculation of the process water. Some <br />water will be consumed by evaporation and within the product stream. This make-up water will <br />be provided by the permitted water source. No washing of material will occur until the permitted <br />water source is available. Waste fines from the washing will be dewatered and either sold or <br />dumped into the fines storage area. <br />To improve recycling of the process water, a non-toxic flocculent may be used in the settling <br />ponds. Flocculent use will occur if the residence time in the pond(s) is insufficient to settle most <br />of the suspended solids. Hyperfloc AF852 produced by Hychem, Inc. is commonly used within <br />the state. The chemical is not harmful to fish or other animals unless it is dumped in full <br />concentration directly into an active stream in large quantities. It is one of the safest flocculants <br />and is currently used by the City of Denver in its drinking water plants. Product information <br />including MSDS have been included with this application. <br />As per the typical installation in the state, a large stock tank will be utilized as spill containment <br />for the flocculent dosing system. Within the stock tank, one 150 -gallon water tank will be set up <br />as a mixing tank. A 55 -gallon steel drum of Hyperfloc will be set up next to the mixing tank. <br />Water will be recirculated from the settling ponds into the mixing tank where the flocculent will <br />be added at the recommend rate of 0.5-20 ppm. A spill kit will also be kept near the dosing system <br />in the event a spill occurs outside the secondary containment of the stock tank. Additional drums <br />of Hyperfloc may be stored within the mill buildings spill containment area. <br />Import of Material <br />The quarry would like to accept import material from construction projects within the region as <br />well as material to be milled or blended with milled material. This request has been driven by the <br />requests of current clients of CaIX and the Yule Quarry. Import material from construction sites <br />would be utilized as fill material for reclamation purposes, topsoil for reclamation purposes, <br />recycled through the site's plants for resale, or used to expand the working area around the mill <br />building by filling within the fines storage area. <br />Import material will occur in accordance with the requirements of Rule 3.1.5(9). Imported material <br />will be dumped on a bench within the quarry for inspection. If the material does not meet the <br />criteria of inert material as defined (below) by the DRMS it will be reloaded onto the truck and <br />sent away from the site. <br />"Inert Material means non -water-soluble and non-putrescible solids together with <br />such minor amounts and types of other materials, unless such materials are acid or <br />toxic producing, as will not significantly affect the inert nature of such solids. The <br />term includes, but is not limited to, earth, sand, gravel, rock, concrete which has <br />been in a hardened state for at least sixty days, masonry, asphalt paving fragments, <br />and other inert solids." <br />
