protected from any slides and/or sedimentation occurring from the waste rock landform <br /> during mining and reclamation. Will any additional BMPs be installed during reclamation <br /> of the waste rock lifts to protect these areas from erosion while the vegetation is <br /> establishing? <br /> The Young Ranch Resource Quarry is committed to preserving all waterways and has planned <br /> to reclaim the WRL from the bottom up to ensure that the base of the WRL is stable, <br /> 'unslideable', and unable to be impacted by natural events such as 100-year storm events. By <br /> reclaiming each lift as it is built, the WRL will be stabilized from erosion via the coarse blasted <br /> rock detailed throughout the permit narrative as well as by grass and tree roots planted within <br /> and around the coarse blasted rock. Prior to the establishment of vegetation, straw wattles will <br /> be installed along the base of the first lift of each limb of the WRL to ensure that fines do not <br /> travel away from the site. These straw wattles will be inspected weekly and after every major <br /> storm event for any needed repairs and said procedure will be included in the site SWMP. <br /> 58. On page G-5, the application states "expected groundwater levels are known to be <br /> greater than 500 feet below the pre-mined ground surface based on well and spring data <br /> in the surrounding area". Please identify the location of any known springs/seeps that <br /> occur in the proposed affected lands on the Figure G maps. During the pre-operation <br /> inspection conducted on August 4, 2021, the Division observed multiple areas where <br /> saturated conditions existed within the larger drainage in which the proposed waste rock <br /> landform would be constructed. It was difficult to tell whether these saturated areas were <br /> from recent precipitation events or from seeps. The Division did identify a seep at the <br /> bottom of the larger drainage which had a discernible flow, estimated at approximately 1- <br /> 2 gpm. Please include in this exhibit a discussion of any springs/seeps that occur in the <br /> drainages of the proposed waste rock landforms, any impacts these conditions might <br /> have on the stability of the waste rock landforms, and how any water draining from the <br /> base of the waste rock landforms will be managed during operations and reclamation. <br /> Revised Exhibit G figures and Appendix 1 maps show the general cross section of the mining <br /> plan and the known groundwater level and seep locations. Additionally, please refer to the ERC <br /> prepared Aquatic Resource Delineation in Appendix 7 that details the seep location and aquatic <br /> resources for the site as a whole. <br /> 59. Please provide a generalized cross-section of the proposed mine site, showing the <br /> proposed pit floor elevations (during mine phase 3) with respect to the elevations of <br /> Clear Creek(to the south), Russell Gulch (to the north) North Clear Creek(to the <br /> north/northeast), the approximate groundwater table in the area, and the screening <br /> depth (if unknown, the total depth) of any wells located within 600 feet of the proposed <br /> permit area. <br /> See the revised Exhibit G map G-3. <br /> 60. On page G-6, the application states up to 40,000-50,000 gallons of water a day will be <br /> trucked in from a legal source. Please specify the anticipated source for this water. <br /> Additionally, please clarify if the projected amount of water needed would include gravel <br /> washing. <br /> December 2021 20 Lewicki& Associates <br />
