13. On page D-1, the application states fencing and/or signage will be installed in some areas but not others. Please describe how the affected land boundary will be delineated in accordance with Rule 3.1.12(2), which requires the affected area be marked by monuments or other markers that are clearly visible and adequate to delineate such boundaries. The affected land boundary will be delineated via T-posts and signs where it is not fenced. All signs—whether fenced or T-post locations—will be spaced within line of sight of the next adjacent sign. 14. On page D-2, the application states "independent of realigning the Central City Parkway, the proposed road corridor may be used as an internal mining access road". Please clarify if the new road will be constructed regardless of whether the Central City Parkway is realigned. If so, please describe how this road would be blocked off from public access. Additionally, if the existing parkway location continues to be used by the public during mine phase 2, how will the waste rock landform be accessed by the operation during that time? Will haul trucks use the parkway to access this area? Or will a conveyor system be used? Please refer to Maps C-6 and C-7 for the grading plan for the mine road and response#11 and the introductory response narrative for further clarification of the proposed use. This mine access road will be graded and fenced or gated to remain separate from the Central City Parkway. Therefore, the road will not be accessible from the Parkway by either the public or by anyone related to the mining effort without City and Division review and approval. Map C-6 details how access will be granted to the western half of the quarry. First and as an example, a light vehicle (LV) will enter the site via the CCP underpass adjacent to the WRL. They will then travel down the ramp created during phase 4 mining. Approximately where this ramp terminates at the phase 4 floor, a LV will be able to enter the central and internal mine access road. Traveling north along this road allows access to the western half of the quarry and the western phase 4 bottom. 15. On page D-4, the application states "In general, each new mining phase will be mined by first excavating vegetation and 0-24 inches of decomposed plant material and sandy loam with front-end loaders, excavators, and bulldozers from the first horizontal bench". Is this material expected to be used as a growth medium for reclamation? Where will this material be stored on site? Please ensure any proposed growth medium or overburden stockpiles are shown on the applicable mining plan maps in Exhibit C. Due to the high variability of the depth of decomposed plant material and sandy loam, long term stockpiling of said organic matter will not be possible. Only decomposed plant material and sandy loam from the first bench or two will be saved and stored in `Reclamation Material' stockpiles as shown on Map C-3. Stripped organic matter from bench 3 and following will be transported directly to the WRL or saved to be used in Reclamation, as needed. The site will use concurrent reclamation such that minimal amounts of reclamation materials will need to be stockpiled at any given time. Any temporary stockpiling of reclamation materials will occur in the phase 1 processing area, see Map C-3. Reclamation materials include partially decomposed plant material and sandy loam (overburden); coarse blasted rock aka `rock mulch'; and crusher fines, as needed. Additional coarse blasted rock will be stored on the active lift of December 2021 5 E Lewicki&Associates
