Will the "proposed yard area and material stockpile area" in Phase 4 be mined? Is that designated area to remain in that location throughout the operation? If that is to be the specific processing area, please indicate where stripped and stockpiled topsoil will be kept, and where any possible stormwater control structures will be located. With all the clarifications requested above, it may be most expedient to revise the maps and resubmit them. Exhibit D - Minin¢ Plan The questions below are asked with the main intention of allowing a more representative reclamation cost estimate to be calculated. Please respond to each item. The acreage figures stated herein, as mentioned above, do not clearly correspond to those stated elsewhere in the application. For example, please state the area and setback distances to be not affected, for any easements and/or the living snowfence. Does the total acreage to be affected at one time also also include roadway acreage, which presumably will also be reclaimed at the conclusion of mining? You briefly describe the excavation, stockpiling, and processing of aggregate material. A reference is made elsewhere in the application to providing this material for concrete and asphalt batching, though it appears that the hatching might occur offsite. A possibly conflicting statement under Exhibit G (Water) indicates that concrete hatching may occur on the site, though no details of this activity are provided in this exhibit. Please clarify or provide the necessary information on this. No mention is made herein to the depth of topsoil to be stripped prior to mining. The soils descriptions state that potential topsoil depths for the four soil types on this area range from six to eight inches; the reclamation plan in Exhibit E states that topsoil will be replaced at depths of two to eight inches. Please provide the necessary information. (Please note: all areas to be affected, not just by excavation, but also by stockpiling, processing, road construction, stormwater control structures, etc., should be stripped to protect that topsoil for reclamation.) The mining map shows the easements for a canal and a ditch on or in the vicinity of the south edge of the site. It is presumed that either of these water conveyances might not be lined, and may therefore be subject to some degree of water loss through percolation. Additionally, there is at least one "recharge pit" near your proposed gravel pit. The soils descriptions indicate that much of the sails in this area exhibit fairly rapid percolation. Please state whether the possible seepage of percolated waters into the pit has been considered, since that can be regarded as exposure of groundwater. Does the proposed plan allow for a sufficient minimum distance between the nearest ditch or recharge pit and the closest wall of the gravel pit? You might want to contact the Division of Water Resources (Alamosa office) for better information on exposing water in your pit. As mentioned above, please clearly state whether there are specific structures to be avoided by mining, or what setback distance will be observed, such as from the house or outbuilding, from any existing tree plantings, from the access road, and/or from any of the permit area boundaries or phase boundaries. [fmining-related activity is to occur within a certain distance, please specify what activity that will be be, such as excavation, roadway, topsoil stockpiling, etc. Please describe in more detail the equipment and/or structures to be contained in the processing yard. Will there be a fuel and tube storage facility? (Please note that fluid vessels stored onsite must have adequate secondary containment. This must be adequately sized to contain a potential spill of all stored fluids, and must include an impermeable layer to protect soil and groundwater.) Please comment or provide the necessary information. Wil] any of the processing facilities require permanent structures? Do you plan to install a scale and scalehouse? You stated that the access road is already constructed, and that it is to be at least partially reclaimed. Please provide measurements of its width, depth of fill, and length. Please comment on these structure-related questions.
