b. Ore Stockpile Area <br />Ore will be dumped directly onto the ore stockpile pad located west of the JD -9 <br />portal by the buggies. The stockpile pad has been sized to contain up to 300 tons of <br />ore. The ore pad covers approximately 2500 square feet (< 0.1 acres). The ore pad <br />will consist of a compacted clay liner. The clay will be placed over an area of 60 ft x <br />60 ft, while the ore pad itself will be 50 ft x 50 ft. The clay is specified to meet a <br />low permeability criterion of 1 x 10 cm/second as determined by ASTM D 5084. <br />The ore will be stored only temporarily onsite, and will be completely removed prior <br />to site reclamation as discussed in Exhibit E. During reclamation of the pad, the <br />compacted clay will also be removed and placed in the mine. <br />A front -end loader will load the ore into haul trucks. Fugitive dust will be minimal <br />because the ore will have a high moisture content and the loading area will be treated <br />with magnesium chloride or watered as needed to minimize dust. Ore haulage will <br />be performed by contractors who will be required to obtain all necessary permits and <br />clearances, follow Department of Transportation regulations including establishment <br />of spill control plans, and obey Colorado traffic laws. <br />c. Topsoil Excavation and Stockpile Areas <br />Since JD -9 was active prior to the reclamation laws, no topsoil was salvaged from <br />any of the disturbance areas prior to this amendment. The surface material in this <br />area is rocky, which limits the amount of salvageable topsoil. The finer waste <br />material will be used to compensate for lack of topsoil. This material has proven <br />effective in supporting re- vegetation of several mines in the vicinity, and, in <br />combination with pocking, it is expected the same will be true for the JD -9 Mine. <br />End dumping will be used at the JD -9 Mine. This leads to natural segregation of the <br />finer waste material from the larger material which will make the finer waste <br />material easily salvageable. It will be stored on the pad west of the portal. <br />Pinon pine, juniper, scrub oak, and any other small trees will be removed from <br />previously undisturbed areas prior to stripping any available topsoil. These trees and <br />other woody material will be placed in separate piles. <br />d. Water Treatment Facility <br />Water Treatment Building <br />A water treatment facility is on the Upper Mine Area, and consists of a 16 ft x 12 ft <br />water treatment building and a pair of treated water settling ponds. The ponds <br />presently onsite will be replaced with 2 new lined ponds, which are shown on Figure <br />C -4. The old ponds will be reclaimed and the area may be used for future imported <br />topsoil storage. Initially, 2 million gallons of water will have to be pumped out of <br />the mine and into the new ponds to facilitate re- opening. During active mining, the <br />pump will run on an as needed basis. In compliance with CDPHE discharge permit <br />D -7 <br />
