t � , Page 3 Mr. Eric Scott September 29, 2017 (a)Locate on a map(in Exhibit C)tributary water courses, wells springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations. - The required geological attributes are shown on the maps. At this time, the figures submitted show at least 4 groundwater wells on or adjacent to the permitted area. The text provided does not identify or provided any information for any of these wells, and in fact, list a well ID that does not appear to be shown on the provided map at this time. Please revise for completeness and consistency between text and maps. - There was some incorrect information the original maps. The information shown on the maps has been updated. The wells surrounding the Site via a search on the Division of Water Resources website show the following wells. - Permit 1244775- "old"domestic well owned by the L ee's(currently permitted for mining) - Permit 150985--MH-Monitoring well located on the Serfer Pit Permit#78322-F-Gravel Pit Permit Well(N/A) Permit#12168--R-irrigation well north or the North La Poudre Mine Site EXHIBIT L -Reclamation Costs(Rule 6.4.12):(1)All information necessary to calculate the costs of reclamation must be submitted and broken down into the various major phases of reclamation. You must provide sufficient Information to calculate the cost of reclamation that would be incurred by the state. The current bond for the site was calculated for reclamation of all exposed groundwater utilizing the previous DRMS policy of bonding for 20%of the total slurry wall cost utilizing a$'3 per sq ft rate for estimating total slurry wall installation costs. This policy has been rescinded and the permitee will now be required to submit financial warranty for the full cost of lining or backfilling as appropriate for the approved reclamation plan. This should also include cost for installation of appropriate flood control structures for reservoir in the flood plain. -The current bond is$915,820. The recalculated bond is$1,274,808.52. See attached Table. Please provide a detailed reclamation estimate including tasks and unit rates for completing the reclamation as proposed in Exhibits E and F. In addition to grading, topsoil replacement, and revegetation, this estimate shall include costs for draining,re-sloping, fully lining or backfilling all exposed groundwater areas, and installation of flood control structures as appropriate. If the SEO has approved the liner for the eastern "slurry lined pond"please provide a copy of the approval documentation. -See updated Table and attached documentation. EXHIBI T S-Permanent Man-Made Structures(Rule 6.4.19):Please note that roadways and abo ve-ground or underground utilities(if present)within 200 feet of the proposed affected area are considered permanent man-made structures. In accordance with Rule 6.4.19, when mining operations will adversely affect the stability of any significant, valuable and permanent man-made structure located within 200 feet of the affected area, the applicant may either. a.)Provide a notarized agreement between the applicant and the person(s)having an interest in the structure, that the applicant is to provide compensation for any damage to the structure;or-The notarized agreements have all been mailed to all structures owners to best of the permitees knowledge. An engineering analysis has also been performed. See attached letter. b.) Where such an agreement cannot be reached, the applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining operation. -The ponds have been reclaimed for at least 15 years. The only pond remaining reclamation is the"Wildlife Pond",this pond is finished mining and has been like this for at least 3 to 4 years. There has been no negative impacts to surrounding structures and has withstood a significant flood in 2013.
