2.05.3 Facilities <br />2. The applicant should provide complete dimensions for each of the <br />existing or proposed buildings at the mine. Building heights are <br />needed in order to verify the estimates for structural demolition <br />costs provided on Page 13-61a. Dimensions of the explosives <br />rtiagazine(s), drop trailers, substation and anfo silo should also <br />be provided, as well as an estimate of the volume of material <br />contained in the outside warehouse facility and old "bone yard" <br />area. The description of powerlines in this section of the <br />application should include information on which powerlines will <br />need to be removed during final reclamation. Table 12-3a, <br />Culvert Specifications, should be amended to list culvert <br />lengths. This information is necessary in order to estimate <br />culvert removal costs. <br />RESPONSE: <br />Dimensions for buildings have been provided on Page 12-21 of Tab 12. <br />Table 12-3a, Culvert Specifications, has been revised. All other <br />information requested is provided in Tab 13. <br />2.05.3 Backfillino and Gradino <br />• 1. Information provided on Page 12-52 of Volume 2 of the renewal <br />application regarding backfilling final pit areas indicates that <br />"the area above the (final) cut must be drilled and shot in order. <br />to fragment the overburden so it can be pushed with dozers into <br />the final pit." The application should indicate which specific <br />pit area(s) this activity applies to, and for which areas this <br />activity has previously been approved. Additionally, it is <br />unclear from the information in the renewal application what the <br />proposed plan is for backfilling - overburden material remaining <br />from the initial Wadge pit box cut. The backfilling and grading <br />plan portion of the renewal application should be amended to <br />describe the present location and volume of this overburden <br />material and include a description of how and where the material <br />will be placed once mining activities have been completed. The <br />application should also be revised to indicate what remaining <br />mining and reclamation activities are planned in the two <br />pit/auger areas located in the W 1/Z Sec. 2 and SE 1/4 Sec. 11. <br />The information provided should include a schedule of when each <br />of the areas will be backfilled and graded. <br />RESPONSE: <br />Text has been added to explain backfilliny final <br />initial Wadge box pit. Table 12-5 has been added to <br />mining and reclamation activities in each pit area. <br /> <br />pit areas and the <br />reflect timing of <br />17 Revised 8/27/86 <br />
