4. Topsoil and Overburden Handling <br /> Topsoil will be salvaged from the mined,processing, hot plant and stockpile areas and placed in <br /> temporary perimeter berms surrounding the disturbed area. Piles are shown at the perimeter of <br /> the permit boundary on the Mining Map, the maximum disturbance limit. Topsoil stockpiles <br /> will be created by stripping the minimum required disturbed area as required by each year's <br /> mining. If additional area is required to be disturbed, the pile will be pushed or moved further <br /> out to the new perimeter of the disturbed area. Topsoil is expected to be approximately 3 inches <br /> and overburden is expected to be approximately 6 inches. The topsoil and overburden berm will <br /> be used during reclamation, will be constructed to 3H:1 V slopes or shallower, and will be <br /> seeded within 180 days of pile establishment with native rangeland grasses to stabilize the <br /> topsoil stockpile until reclamation is in process. <br /> 5. Schedule of Operations <br /> Mining, screening, and processing will be conducted with portable equipment between August <br /> and December 2022. Mining operations will be dictated by the project schedule. Mining may <br /> take place 6 days per week for the duration of the reconstruction project. The product will be <br /> hauled to the construction area nearly as fast as it is produced. <br /> 6. Cheyenne County Impacts and Environmental Impacts <br /> The impacts to Cheyenne County will be limited. No dust is expected from the operation as the <br /> pit and roads are watered as needed. If airborne dust is observable, immediate action to mitigate <br /> dust via roadway wetting. Water used is purchased and brought on site and applied on an as- <br /> needed basis to control dust on haul roads and within the mine area. <br />
