<br />-2- <br />If these dikes are owned by entities other than the applicant and exist <br />within 200 feet of proposed affected land, then a copy of a damage <br />compensation agreement must be provided to the Division by <br />October 15, 1990. Failure to obtain such an agreement will require <br />establishing a 200-foot activity setback from these structures until <br />the agreements are reached. As an alternative to the agreements and <br />the 200-foot setback, you may demonstrate that the proposed operations <br />will not adversely affect the stability of the dikes. <br />3. How far off the ground are the utility lines? Is there a potential <br />danger of raised equipment, such as loader buckets, dragline booms, or <br />dump truck beds, coming in contact with these lines? If so, how will <br />this be prevented? <br />4. Are there any underground permanent, man-made structures located in or <br />within 200 feet of the proposed affected land? Such underground <br />structures would include natural gas pipelines, communication and <br />utility cables, and sewer and water lines. If there are, damage <br />compensation agreements must be obtained for these structures as well. <br />5. Please explain why the proposed permit boundary extends to the east <br />side of the South Platte River, when it appears that all affected land <br />will exist west of the river. <br />6. Neither Map C nor Map F portray the existing or proposed final <br />topography with contour lines of sufficient detail to identify the <br />direction and rate of slope of the affected land. Five-foot contours <br />or even two-foot contours may be necessary to comply with <br />Rules 2.1.2(4)(c) and 2.1.2(7)(al. Please address. <br />7. Because of the nature of the operation, it is apparent that stockpiled <br />material may need to be handled more than once during mining to allow <br />for equipment access, processing plant relocation and ma teriai <br />placement. Please indicate in Exhibit C which stockpiles will be <br />topsoil and which will be overburden. Overburden may be rehandled for <br />space purposes but topsoil, per Rule 6.4(4), may not until respread for <br />reclamation. <br />8. It is apparent that there will be approximately 279,2ti8 cubic yards of <br />overburden excavated by this operation. This is based on the combined <br />acreage of the three excavation phases (51.7 acres) and the depth of <br />overburden described on page D-1 (three feet). While some of this <br />overburden has been proposed for reclamation, it is apparent that a <br />large portion will not be. Please provide the amount of overburden <br />that will be removed by mining, the amount proposed for reclamation, <br />and where the balance will go. <br />9. Recent telephone discussions and correspondence in the Division's files <br />indicate you are working with the U.S. Army Corps of Engineers to <br />obtain a Section 404 Dredge and Fill Permit. Have any of your proposed <br />mining or reclamation plans changed in your MLRD application as a <br />result of your discussions with the Corps? If so, what are they? <br />
