The existing excavation is shown on the revised mine map. The intend is to reclaim this area. The banks have already been sloped, seeded, and covered with straw. 2. The reference to berms on item C.7 was a typo. No berms are proposed on site. The revised page is attached. 3. The permit boundary has been revised so that the cedar trees will be in the permitted area. This added acreage between the cedar trees and the Duke Energy right of way will be used for agricultural purposes only. The revised bond calculation page in attached. 4. The 25' buffer between the excavation area and the property owners to the west has been revised to an undisturbed buffer. This area has well established thick brush/trees that is 20' high or more. This vegetation will remain for screening and dust control. Additionally, a 25' unexcavated buffer has been added between the undisturbed buffer and the excavation area. Two copies of the revised map and additional information are enclosed. If you have any questions or need additional information, do not hesitate to contact me at (252) 258-4037. Sincerely, Marc K.

Cross-sections for all cut slopes must be provided on the mine map(s). A 3 horizontal to 1 vertical or flatter angle will be provided to the water line and 2 horizontal to 1 vertical below the water line. See detail on mine map. D)In hardrock excavations,specify proposed bench widths and heights in feet.Provide cross-sections of the mine excavation clearly noting the angles of the cut slopes, widths of all safety benches and mine benches,and the expected maximum depth of the excavation. N/A 7. Describe other methods to be taken during mining to prevent physical hazard to any neighboring dwelling,house, public road,or public,commercial or industrial building from any mine excavation. Locate all such structures on the mine map if they are within 300 feet of any proposed excavation. An adequate unexcavated buffer zone will be maintained around the entire site. See map. The site is naturally screened by existing woods on the all sides and will not be visible to the public. No explosives will be used. A gate will be installed at the construction entrance. See mine map. All structures within 300' are shown on the mine map. 8. Describe what kind of barricade will be used to prevent inadvertent public access along any high wall area and when it will be implemented.Vegetated earthen berms,appropriate fencing and adequate boulder barriers may be acceptable high wall barricades.A construction detail/cross-section and location of each type of barricade to be used must be indicated on the mine map(s).

Please insert the approximate acreage, for each aspect of the mining operation,that you intend to affect during the life of this mining permit(in addition,please insert the appropriate reclamation cost/acre for each category from the Schedule of Reclamation Costs provided with this application form) OR you can defer to the Department to calculate your bond for you based upon your maps and standard reclamation costs: CATEGORY AFFECTED RECLAMATION RECLAMATION ACREAGE COST/ACRE COST Tailings/Sediment Ponds Ac.
