Lewicki & Associates ENGINEERING I GEOLOGY I ENVIRONMENTAL December 20, 2021 RECEIVED Amy Eschberger DEC 2 9 2021 Environmental Protection Specialist Colorado Division of Reclamation, Mining and Safety DIVISION OF RECLAMATION, 1313 Sherman Street, Room 215 MINING&SAFETY-MINERALS Denver, Colorado 80203 (303) 866-3567 Delivered Via Email and Fedex/Hand Delivery RE: Young Ranch Resource Quarry (M-2021-009), Preliminary Adequacy Response Ms. Eschberger: On behalf of the Young Ranch Resource, LLC, please allow this letter to serve as response to your August 23, 2021 dated Preliminary Adequacy Review for the Young Ranch Resource quarry, Colorado Division of Reclamation, Mining and Safety (CDRMS) File No. M-2021-009. All page number, map and appendix call outs refer to the CDRMS 112c permit application package dated December 20, 2021. An additional element of the Young Ranch Resource quarry mine plan is a proposed future realignment of the Central City Parkway (CCP). Realignment of the CCP is an option that will be analyzed and approved at the discretion of Central City. We feel strongly that this is a desirable option for the City but have not received official guidance from the City regarding their current interests in pursuing this option. Designs shown on Maps C-6 and C-7 include grading designs that will accommodate the realignment. If the city chooses not to pursue the realignment option, the grading plan will remain internal to the mine and no public access will be allowed off of the CCP at either end of the proposed road realignment corridor; said road corridor will continue to be used exclusively as an internal mine road. In the event the Young Ranch Resource seeks additional future mine access points that utilize this grading plan and alignment, the Young Ranch Resource understands that doing so would require both an access agreement with the city and CDRMS approval through their Technical Revision (Technical Revision) process. The internal mine road will remain post reclamation and serve as access to the area for post reclamation use and management and may, pending City approval, contain private Young Ranch Resource access points that connect the internal mine road directly to the CCP. If the City chooses to realign the CCP, the Young Ranch Resource, LLC will submit final, city approved, road design specifications and drawings to the Division for review and approval through the appropriate approval process prior to construction of any changes to the current design. A realignment of the CCP would require final design specifications that may include, among other things, a wildlife overpass and fencing in the area of the wildlife corridor and an underpass and on/off ramps to accommodate mine access to the realigned CCP.
