Does the permittee intend to conduct additional mining in this area to expand the <br />lake size? <br />EXHIBIT E - Reclamation Plan (Rule 6.4.5): <br />The reclamation plan states that the currently reclaimed areas, and areas that may be re- disturbed or will <br />need additional reclamation are depicted on the Current Conditions and Reclamation Plan maps — these <br />acreages do not seem to be shown on the maps provided. In addition, the provided black and white /pattem- <br />fill maps are attempting to depict so much information that they are already difficult to read. Please provide <br />this additional information either on another map, or perhaps provide color keyed maps to depict the <br />information shown. <br />DRMS will not allow "Option 1" as described for revegetation on page 8 of the submitted reclamation plan. <br />Seeding with the approved seed mix will be required. Please remove "Option 1" from the reclamation plan. <br />DRMS may allow for the release of the site prior to the full establishment of vegetation to facilitate <br />construction activities as outlined in "Option 2 ". <br />The contouring shown on the map provided for reclamation "Option C" appears to result in a large <br />depression that would not allow any surface drainage from the eastern portion of the site. How will the <br />permittee insure that water does not remain standing in the resulting basin, especially after major <br />precipitation events in such close proximity to the river? State Engineer's Office (SEO) Division of Water <br />Resources rules state that storm water will not be retained onsite for over 72 hours. <br />EXHIBIT F - Reclamation Plan Map (Rule 6.4.6): <br />Please refer to first comment on reclamation plan regarding depiction of acreages to be reclaimed, and/or <br />currently reclaimed. <br />EXHIBIT G - Water Information (Rule 6.4.7): <br />The second paragraph of Exhibit G states that five monitoring wells have been installed on site, however <br />they do not appear anywhere on Exhibit C as stated. Please provide a map showing the locations of these <br />wells, and the associated monitoring well boring and well construction logs for the five new wells. LG <br />Everist will also need to commit to making the monthly groundwater level data collected a part of the <br />annual report submitted to DRMS for this site. <br />EXHIBIT L - Reclamation Costs (Rule 6.4.12): <br />Recalculation of the reclamation bond will be required. Please adjust the bond calculations to include the <br />following: <br />100% of the cost of the western slurry wall must be submitted. DRMS has not yet been provided with any <br />detailed plans or design specifications for that slurry wall to -date. To qualify for the 20% bonding option, in <br />addition to providing adequate plans and design specifications to DRMS for approval, the permittee will <br />also need to provide construction QA/QC data to support that the slurry wall was installed in full <br />compliance with the design specifications, or pass the SEO testing criteria. So you are aware, the 20% <br />bonding option "policy" for slurry walls is currently under review by DRMS and may not be an available <br />option in the future. <br />
