Mr. Bill Tczai August 24,2021 Page 6 of 9 How does the operator intend for the mined area to be free-draining after mining is completed so that it does not retain surface runoff or precipitation as it does currently? The contours provide on the current reclamation plan map would seem to indicate a closed basin in the southern area of the excavation. Has any geotechnical stability work been conducted to confirnVdocument the assertion that the proposed benched slope configuration will be stable post-reclamation? Are any measures being taken with runoff control or bench grading to keep the overburden and topsoil in place after reclamation? Level benches can tend to shed topsoil during heavy precipitation events if runoff is not properly managed EXHIBIT F-Reclamation Plan Man (Rule 6.4.6): The map(s) of the proposed affected land,by all phases of the total scope of the mining operation, shall indicate the following: (a)The expected physical appearance of the area of the affected land, correlated to the proposed mining and reclamation timetables. The map must show proposed topography of the area with contour lines of sufficient detail to portray the direction and rate of slope of all reclaimed lands; The provided reclamation map does not show sufficient detail for theproposed benching configuration,please address. Pleaseprovide cross sections in at least two locations/directions across the proposed final mine configuration showing the proposed bench configurations,slopes and reclamation. (b)Portrayal of the proposed final land use for each portion of the affected lands. EXHIBIT G-Water Information(Rule 6.4.7): (1)If the operation is not expected to directly affect surface or groundwater systems, a statement of that expectation shall be submitted. What is the depth to groundwater in the proposed mining area? Can the operator demonstrate that the water currently retained in the pit is precipitation and not exposed groundwater? Does the operator intend to implement any measures to route precipitation around and away from the mined areas so that it is not captured/inipacted? (2)If the operation is expected to directly affect surface or groundwater systems,you shall: (a)Locate on the map (in Exhibit C)tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations; (b) Identify all known aquifers; and (c) Submit a brief statement or plan showing how water from dewatering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater(and, where applicable, control pollution in a manner that is consistent with water quality discharge permits), both during and after the operation. (3)You must provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project.
