ADEQUACY ISSUES PERTAINING TO AREAS OTHER THAN THE PROPOSED NEW PERMIT AREA <br />6. Response adequate. <br />7. Please revise the mine plan map to show the topsoil and overburden stockpiles that will be generated <br />by stripping of the AM-02 area, the AM-03 area, and the remaining west lake parcel. <br />8. There appears to be 500 linear feet of highwall along the Laughery home site where the buffer zone is <br />too small to allow for cut and fill highwall reduction. The maps also indicate the lake separator between <br />the Black property and the Laughery property will not be cut and filled, but must be backfilled to the final <br />approved 3H:1V grade. Full backfill of these sections will require much more material. It appears that <br />there is inadequate overburden resources on site to complete this backfilling. If salvaged and waste <br />materials from the adjacent batch plant property are to be used as a component of the backfill for this <br />site, please provide calculations to demonstrate the amount of material that is required to be imported,- <br />to create the final slopes and re-build the separator between the north and east lakes. Verification that <br />this volume of material is available on the adjacent property, and that it will be maintained there until it <br />is imported and placed, will also be required. Importation costs in exhibit L may need to be revised. <br />9. Response adequate. <br />10. See comment no. 5 above. <br />11. Please be aware that the two riverbank stabilization structures along the west parcel, outside the permit <br />area are not features that are under DMG's jurisdiction. Installation of these structures appears to be a <br />good idea and is recommended, but they will not be included in this permit. The proposed structure on <br />the northeast corner of the site is on the permit boundary and will be required. Please provide detailed <br />construction and engineering specifications for this protection structure. <br />12. Please provide a commitment to conduct no excavation that will result in increased water surface <br />exposure, until an approved water augmentation plan is in place that allows for this additional exposed <br />water surface. <br />13. Please revise the reclamation plan map to show the 940 linear feet of 5H:1 V final pit slope that was. <br />committed to in-AM-01 (this slope is currently shown at 4H:1V or less), the 7H:1V permanent ramps, <br />indicate where the various types of vegetation will be planted including estimated shrub clump <br />locations, and indicate where the various goose nesting boxes have been and/or will be installed (they <br />are not shown on the map as stated). Also, please revise the reclamation plan map to show the west <br />lake parcel in it's final configuration. <br />14. Willow, sumac and buffafoberry to be planted are all shrub species. As such, the proposed shrub <br />clump planting details should be revised to a spacing of 10 foot centers. Please specify how many <br />tublings this planting scheme will require. <br />15. If the mining and reclamation plans are to be a complete replacement for the currently approved mining <br />and reclamation plans, then there are several more features of these plans that need to be added. <br />Features such as, secondary containment for hazardous materials, provisions for the asphalt batch <br />plant, benched mining operations, goose nesting box design (for future reference).. Most of these <br />details can be found in TR-1. <br />DMG will calculate the reclamation cost estimate based on current reclamation liabilities. United companies <br />will be required to submit that financial warranty within 60 days of receipt of the mailing date of that bond <br />calculation. If a significant portion of the reclamation is completed prior to that date, as it should be if the south <br />
