slopes. To prevent erosion, the stockpiles will be seeded with the native seed mix detailed in <br /> Exhibit F within 180 days of establishment. <br /> Stockpiles recovered as the result of opening Phase 1 will be stored in the processing area and <br /> will be used to provide sediment control for the processing area. Overburden from Phase 1 <br /> and/or the processing area will be used to build-up the processing area sediment control structure <br /> and will be topped with topsoil from Phase 1 and/or the processing area. Each subsequent <br /> phase's recovered materials will be used to reclaim the previously mined strip within the <br /> adjacent phase and will not be stockpiled. <br /> Anticipated topsoil to be removed and stockpiled in undisturbed future mining areas amounts to <br /> 360,040 CY and is equal to the amount required during reclamation of all disturbed areas with a <br /> topsoil application of 6 inches. Anticipated overburden in all unmined areas to be removed and <br /> stockpiled totals to 4,320,470 CY and is equal to double the required volume of 2,160,240 CY <br /> needed for reclamation of all disturbed areas with a replaced overburden depth of 3 feet. These <br /> are estimates based on the NRCS soils report, average known topsoil and overburden depths, and <br /> the previous permit's boring results. <br /> 5. Schedule of Operations <br /> Mining operations will occur Monday through Saturday during daylight hours and intermittently <br /> during the life of the operation. Mining, screening and processing will be conducted with <br /> portable equipment at various times of the year. Product will be sold throughout the year. Night <br /> mining will not occur; although minor truck activity or repairs may occur after daylight hours. <br /> Mining and processing will take place no more than 12 hours per day, during daylight hours, <br /> Monday through Saturday. Hauling will take place from 7 am to 7 pm Monday through <br /> Saturday. <br /> 6. Huerfano County Impacts and Environmental Impacts <br /> The impacts to Huerfano County will be limited. No dust is expected from the operation as the <br /> pit and roads are watered as needed. In the event that airborne dust is observable, immediate <br /> action to mitigate dust via roadway wetting and a slowdown of production will be initiated and <br /> sustained until airborne dust is mitigated. Water used is brought on site and applied on an as- <br /> Bradford Mesa Quarry <br /> January 2020 D-20 <br />
