C-26 <br /> While minor infiltration will occur via the fines recovery pit(to be purposefully operated as an unlined infiltration <br /> feature), it is anticipated that this activity will effectively establish a short-term to intermediate-term zone of <br /> saturation and/or a localized perched groundwater occurrence of limited areal extent. Similarly,given the separation <br /> distance (which ranges upward to 500 ft. or greater) between such perched groundwater occurrences and the first <br /> encountered economic and sustainable yield aquifer,there will be no measurable impact on the localized or regional <br /> hydrologic balance. <br /> The natural effect of the proposed mining operations will be to establish two discrete, but localized depressions <br /> (e.g., the main mine pit and the fines recovery pit, respectively). Proposed site reclamation activities are further <br /> addressed within Exhibit D: Reclamation Plan; however, in both instances it is anticipated that some degree of <br /> topographical depression will remain subsequent to completion of final site closure and reclamation. Similar to the <br /> effects described above,there will be no measurable impact on the localized or regional hydrologic balance. <br /> (m) MINERAL PROCESSING <br /> All mined materials will be processed onsite, employing both wet (wash) and dry (thermal drying followed by <br /> screening)process unit operations typical of those utilized in the sand and gravel industry. <br /> Components of the mineral processing unit operations are discussed in detail in subsection(e) Major Components <br /> of Mining Operation,more specifically, in part(iv)Processing Plant Facilities, thereof. <br /> The Keenesburg Project processing facilities will incorporate both"wet plant"and"dry plant"facilities. The"wet <br /> plant" will utilize a wet rinse scalper to initially remove oversize material (i.e., greater than#20 material), which <br /> will report to an oversize reject stockpile. As space constraints may dictate, all or some portion of this oversize <br /> material may be subsequently relocated to growth medium stockpile TS-1A, where its placement would serve to <br /> function as an encrusting agent atop the surface and side slopes of the stockpile. <br /> The retained material(i.e.,that less than#20)would then be pumped to a separator cyclone(with cyclone overflow <br /> reporting to a water clarifier unit) and underflow would report to a series of attrition cells to break down clusters <br /> Keenesburg Project_Limited Impact 110 Application_May 24,2019 <br />
