-. <br /> <br />Mr. John Auffrey -3- October 17, 1983 <br />3. Bent County Pit: <br />a. What is the planned maximum depth of mining on the site? <br />b. What are the plans for the "junk pile" shown on the map? What is <br />its present composition? <br />4. Etchart Pit: <br />a. What is the relationship of the "old building" shown on the snap to <br />the mining operation? Is it to be torn down during mining? If so, does <br />the landowner concur with these plans? Otherwise, how is the building <br />to be protected? <br />b. Is the access road to the pit existing, or is it constructed as <br />part of the operation? If it is constructed as part of the operation, <br />it should be a part of the permit area. <br />5. Army Corps of Engineers Pit: <br />a. The rectangular area shown on the map is (by the scale given) 6.2 <br />acres in extent. An irregularly-shaped area is also shaded, and it <br />attaches to the permit area at the northeast corner. Furthermore, an <br />access road is also shown. Is the 6.6 acres given to include the <br />rectangular area plus either the irregularly-shaped area or the access <br />road, or both? If the access road is constructed as part of the <br />operation, it must be included as part of the permit area. Please <br />clarify this matter. <br />6. Smartt Pit: <br />a. Since this operation is to mine a dry creek bed, care must be taken <br />to maintain the flow regime when the creek bed does flow and mining is <br />not occurring. The end slopes of the excavated area (upstream and <br />downstream ends) should be maintained at l0ii:ly between mining <br />episodes. Bank slopes should be maintained at 3h:ly. <br />b. Is mining to occur only in the creek bed itself? Any mining <br />outside of the creek bed must involve topsoil salvage, reshaping of <br />banks, and a consideration of upstream and downstream effects of <br />widening the creek bed (when it flows). <br />c. All topsoil (and gravel) should be stockpiled well up from the <br />creek bed (either above the 100-year floodplain or bermed to resist <br />flooding and loss). Please clarify your plans in this regard. <br />d. lJhat is to be the direction of mining on the site? <br />e. Is the access road pre-existing, or is it to be a part of the <br />pe rnrit area and reclaimed after mining ceases? If the road is to be <br />part of the permit area, the total acreage may need to be adjusted. <br />
