Colorado Rose Red, Inc. Page 2 <br /> Colorado Rose Red Granite Quarry M-1978-332 <br /> I don't know what happened here, my version was complete but looking at the electronic version, <br /> you are correct. Attached is a copy of the entire soils report with the numbers and information as <br /> received. <br /> Rule 6.3.3—Exhibit C —Mining Plan <br /> 3. Page 44 of the mining plan discusses the proposed soil salvaging operation. The applicant <br /> proposes to salvage 0 to 4 inches of soil in about 3.11 acres of forest/open area within the <br /> permit area. According to the web soil survey, for the three soil units found at the site <br /> (2703B, 2705D and 2706D) with the exception of the rock outcrop portions of the soils, there <br /> is generally an A horizon ranging in depth from 0 to 8 inches and a Bw horizon ranging from <br /> 4 to 18 inches in depth. The A horizon and Bw horizon should be salvaged for reclamation <br /> where available. Given the depths of these horizons the proposed plan of salvaging 0 to 4 <br /> inches of growth media does not appear adequate. The Division would accept a plan to <br /> salvage 3 to 13 inches of A and Bw horizon material for growth medium where this materials <br /> is available. Please either commit to this salvaging plan or proposed a revised plan with <br /> adequate justification. <br /> Due to the limited amount of soil on the site the operator will commit to salvaging as much of the <br /> native soil material from areas where it exists. This will average from 3 to 13 inches from the A& <br /> Bw horizons where available. <br /> 4. Please revise the Exhibit E-1 Map to show the location where topsoil/growth media will be <br /> stored. <br /> The Map Exhibit E-1 has been revised showing approximate locations of the topsoil/growth medium <br /> piles . <br /> 5. Surface water will be intercepted at the site, please describe the methods to be used to <br /> minimize disturbances to the surface water system including sediment-containment and storm <br /> water run-off controls. <br /> At the current time water that encounters disturbed area is directed into the spoil pile where it filters <br /> thru the rubble and is contained on site. There are 3 small shallow areas on the existing bench <br /> where water from the water jet collects until it is reused. A catchment basin is being excavated on <br /> the east end of the permit area where all process water will be directed and recycled thru the water <br /> jet system. The revised Map Exhibit E-1 shows the location of this basin and a label has been <br /> added to point it out. During mining on the quarry area small berms will be placed on the setback <br /> area so all off site surface water will be directed away from the mine. These berms will also serve to <br /> keep any stormwater that falls on the site from leaving before it is treated. These berms will be <br /> removed during reclamation. The internal stormwater will be directed to the processing area where <br /> it will be collected in temporary basins and treated prior to release within a 72 hour window We do <br /> not expect there to be large quantities of runoff since the crushed material has a very low water <br /> content and will absorb much of the moisture as it falls. <br /> 6.
