i • t • <br /> l <br /> Mr. William B. Wray, Jr. -2- May 3, 1983 <br /> It is unacceptable to mine and process the topsoil . Pursuant <br /> to C.R.S. 1973, 34-32-116(1 )(g), the topsoil material must be <br /> removed and segregated from other spoil . As recommended by the <br /> Soil Conservation Service, the top 10-12 inches of topsoil must be <br /> salvaged and stockpiled for future use. bA-,vKw•- <br /> Where are the "coarse and medium yrained reject material " <br /> stockpiles? fA.%_Cs> A-2cR <br /> 6. Will the "excess or overflow reject material " have to be <br /> temporarily placed in the water storage area of Housel Gulch only <br /> during the excavation of the first pit, or throughout the life of <br /> this mine? From the Division's understanding, the "reject storage <br /> area" is not in the stream channel , but up on a terrace. Is this <br /> correct? <br /> Where will the pilot plant and crusher be located within the <br /> permit area? o(�) n/`AP <br /> The following questions pertain to topsoil salvaging. <br /> a. What slope gradients will the pile be graded to? The <br /> Division recommends a maximum slope of 3h:ly. <br /> b. Pursuant to C.R.S. 1973, 34-32-116(1 ) (g) , if the topsoil <br /> pile is to last for more than one growing season, the pile <br /> must be seeded. If the pile does last for more than one <br /> growing season, what seed mixture will be used to seed the <br /> pile? The Division recommends a grass species and a legume <br /> species. <br /> What will be used to line the spillway constructed above the <br /> reject material storage area? aq" S�tii p,r.�s u/ Ro�ic !2�P-RaP <br /> B. Exhibit E - Reclamation Plan <br /> N <br /> How deep will the topsoil be respread onto backfilled areas? <br /> How will the seedbed be kept weed-free? <br /> 3. How will the pre-existing water storage area be preserved if a <br /> drainage ditch is established below the reject material storage <br /> area and a lined spillway constructed above this material storage <br /> area (as described in Exhibit D)? <br />
