Page 7 Mr. Eric Scott June 4th, 2021 Demonstration that enough material will be available on-site to backfill the fresh water and sediment ponds at the end of mining, and where it will be staged. (at a minimum, material volume and push distances are required for DRMS bond calcs for all earthmoving) Demonstration that enough material will be available on- site to reconstruct interior slopes in lined reservoir areas for each reclamation option and where it will be staged. Cost to reconstruct interior slopes(4:1?) for lined reservoirs for each reclamation option. Basis for slurry wall unit costs utilized in the provided estimate—if RMCC already has awarded contracts for this work that might be sufficient, otherwise additional information will be needed. Listing of equipment to be utilized to complete needed tasks(scraper, dozer, grader, water truck, etc). DRMS will verify the required bond when the information requested is provided and all remaining adequacy issues have been resolved. RMCC plans on mining and reclaiming the interior slopes at a 3:1 slope eliminating the need for material. If at a later time, RMCC decides to mine at a steeper slope and reclaim with overburden or claystone the Mining Plan and Reclamation Plan will be updated through the Technical Revision process. There is approximately 1,100,000 cy of material required to back fill the siltation and freshwater ponds to existing grade, with the option to place additional material in the same footprint. There is anticipated to be 2,434,000 cy of overburden at the site. Overburden stockpiles have been updated on the attached Mining Plan Map. Since slurry wall construction on the south slurry wall is not planned for more than 5 years, RMCC plans to update the bond to include the south slurry wall prior to starting construction. EXHIBIT M- Other Permits and Licenses (Rule 6.4.13): A statement identifying which of the following permits, licenses and approvals the Operator/Applicant holds or will be seeking in order to conduct the proposed mining and reclamation operations:effluent discharge permits, air quality emissions permits, radioactive source material licenses, the State Historic Preservation Office clearance, disposal of dredge and fill material(404) permits, permit to construct a dam, well permits, highway access permits, U.S. Forest Service permits, Bureau of Land Management permits, county zoning and land use permits, and city zoning and land use permits.
