No activities will occur in the 25' unexcavated buffer. 1 changed this to be a 25' undisturbed buffer. 2. 1 was using the property line as the permit boundary/limits of disturbance. The discrepancy came from areas that were not being disturbed such as ditches and pavement. To make this clearer, I revised the permit boundary/limits of disturbance to be 10.54 acres and revised the outline on the plans. In doing so, I found some of the other areas to be incorrect as well. 3. Cross-section C-C is labeled. 4. For reclamation, an application for an LCID will be applied for during the last year of mining. All berms will be knocked down and stockpiled for use in the LCID. The mine will be filled with land clearing waste, yard waste, untreated and unpainted wood, uncontaminated soil, inert debris, and asphalt. S. Structures were added within 300 feet from Harris Road, as requested. 6. Stormwater will infiltrate into the bottom the pit at all times. The soils show that there is a high infiltration rate; therefore, standing water will not be an issue. The pit will never get within four feet of the seasonal high water table due to the future LCID. The skimmer basin and related details were removed from the plans.

Describe your intended plan for the final reclamation and subsequent use of all affected lands and indicate the sequence and general methods to be used in reclaiming this land.This must include the method of reclamation of settling ponds and/or sediment control basins and the method of restoration or establishment of any permanent drainage channels to a condition minimizing erosion,siltation and other pollution. This information must be illustrated on a reclamation map and must correspond directly with the information provided on the mine map(s).In addition, design information,including typical cross-sections,of any permanent channels to be constructed as part of the reclamation plan and the location(s)of all permanent channels must be indicated on the reclamation map. Once mining activities are complete, all berms will be knocked down and stockpiled for use in an LCID. The mine will be filled in with land clearing waste, yard waste, untreated and unpainted wood, uncontaminated soil, inert debris such as unpainted rock, brick, concrete, and concrete block, and asphalt. The LCID permitting process will begin approx. one year before the mining process comes to an end. Mining will end when it reaches a depth no more than four feet above the seasonal high water table. 2. Is an excavated or impounded body of water to be left as part of the reclamation? YES FX]NO If yes,illustrate the location of the body(s)of water on the reclamation map and provide a scaled cross-sections) through the proposed body(s)of water.The minimum water depth must be at least 4 feet,measured from the normal low water table elevation,unless information is provided to indicate that a shallower water body will be productive and beneficial at this site. Will the body(s)of water be stocked with fish? YES �NO If yes,specify species. 3. Describe provisions for safety to persons and to adjoining property in all completed excavations in rock including what kind of permanent barricade will be left.Acceptable permanent barricades are appropriate fencing,large boulders placed end-to-end,etc. Construction details and locations of all permanent barricades must be shown on the reclamation map.

All overburden will be knocked down and stockpiled on site. 5. A)Describe reclamation of processing facilities,stockpile areas,and on-site roadways. All stockpiles will be used for the proposed LCID used during reclamation. B)Will any on-site roadways be left as part of the reclamation? 1^1YES FINO If yes,identify such roadways on the reclamation map and provide details on permanent road and ditch line stabilization. The haul road will remain. It will be graded to drain to the inside of the pit. The gate with lock will remain. A permanent asphalt apron will be left at the driveway entrance. No further improvements will be made. 6. Describe the method of control of contaminants and disposal of scrap metal,junk machinery,cables,or other such waste products of mining.(Note definition of refuse in The Mining Act of 1971.) No off-site generated waste shall be disposed of on the mine site without prior written approval from the NC Department of Environmental Quality,Division of Energy,Mineral,and Land Resources and either the Division of Waste Management(DWM)or local governing body.If a disposal permit has been issued by DWM for the site,a copy of said permit must be attached to this application.All temporary and permanent refuse disposal areas must be clearly delineated on the mine map(s)and reclamation map,along with a list of items to be disposed in said areas. There will be no such areas at this location.
