ARcosa <br /> Drawings show permanent and man-made structures on the affected lands and within <br /> 200 feet of the affected lands. Table 1 in Exhibit S lists structure owners and a <br /> description for each structure. <br /> (h) Exhibit C-3 shows the USDA soil types present on the affected lands. The types of <br /> vegetation are described in the original Exhibit J narrative. Vegetation types described <br /> therein are coincident with all areas of undisturbed soil on the affected lands. Vegetation <br /> is not present where there are active disturbances from mining and process activities. <br /> Note that maps provided in Exhibit D present surficial geology information for the <br /> affected lands and surrounding areas. Please see the updated Exhibit C-3 map in <br /> Attachment 3, the original Exhibit J narrative provided with the Permit Application, and <br /> the updated maps for Exhibit D in Attachment 3. <br /> (i) Acknowledged. <br /> DRMS Reference (underline)and Comment (italics) <br /> EXHIBIT D - Mining Plan (Rule 6.4.4): The mining plan shall supply the following <br /> information, correlated with the affected lands, maps) and timetables: <br /> (a) description of the methods of mining to be employed in each stage of the operation as <br /> related to any surface disturbance on affected lands; <br /> The mining plan map will need to depict all relevant features of the existing and proposed <br /> operations. These would include, but not be limited to: permit boundary, the locations of all <br /> topsoil, overburden and product stockpiles, active mining areas, proposed mining areas, <br /> processing equipment such as crushers, conveyors,processing plant, waste disposal areas, etc. <br /> The mining plan provided states that there is consumptive use of precipitation and "seep" <br /> water at the site for processing and dust control. Please provide proof that this use of water has <br /> been approved by the State Engineer's Office Division of Water Resources (SEO). Does the site <br /> currently have an SEO approved well permit and substitute water supply plan? Groundwater <br /> exposure, approved usage, and groundwater quality monitoring issues should be addressed <br /> under Exhibit G. <br /> The geologic cross section referred to as Figure D-6 was not part of the submittal — please <br /> include. <br /> What analyses of the process waste material have been conducted to demonstrate that it is <br /> appropriate to dispose of this material in an open pit containing exposed runoff/groundwater? <br /> What analyses have been conducted on the water in the pit to determine if it has been adversely <br /> impacted by the existing waste disposal practices? <br /> Please demonstrate that the current disposal practice of end-dumping this waste material over <br /> the edge of the pit will not adversely impact the long-term stability of the reclamation, or <br /> negatively impact the quality of the surrounding groundwater or water exposed and remaining <br /> in the bottom of the pit area when reclamation is completed. Water issues may also be included <br /> in Exhibit G for simplicity. <br /> (b) earthmoving; <br /> (c) all water diversions and impoundments;and <br />
