No permanent structures will be built within the mining area. Only portable processing <br /> equipment such as a crusher will be brought into the mining pods. All other equipment will be <br /> mobile. Explosives will not be used or stored at the site. <br /> 4. Topsoil and Overburden Handling <br /> Topsoil is roughly 12 inches thick. No overburden is anticipated to be found onsite. Topsoil will <br /> be stripped prior to mining using appropriate earth moving equipment. The equipment that may <br /> be used for stripping includes front-end loaders, dozers, excavators, scrapers, and water trucks. <br /> Topsoil and overburden will be stockpiled separately in various stockpiles throughout the site for <br /> use in reclamation. When possible, it will be directly placed on areas being reclaimed. <br /> Stockpiles that will be in place for longer than 90 days will be seeded with the permanent seed <br /> mix to prevent erosion (see Exhibit E for seed mix). <br /> Table D-2 shows the material balance based on the average topsoil and overburden <br /> thicknesses described above. These volumes account for the estimated topsoil and overburden <br /> stripped from all pods. <br /> Table D-2 Topsoil and Overburden Material Generated During Mining <br /> Material Generated (CY) <br /> Topsoil(12"thick) 155,000 <br /> Stockpiled material will be used to achieve the final grading shown in the Exhibit F reclamation <br /> maps. Screening fines will be used to backfill and grade the final mining slopes at 2H:1V to their <br /> final reclaimed conditions at 3H:1V. Any excess material will be dispersed and graded across <br /> the pod floors and used to create aesthetically pleasing reclaimed slopes. Stored topsoil from <br /> pre-mine stripping will be used to replace the topsoil on all disturbed areas and slopes. Topsoil <br /> will be replaced in a single 12-inch average lift across these areas. <br /> 5. Water Information, Rights, and Augmentation <br /> All water rights issues such as availability of water for this operation, consumption rates, dust <br /> control, etc. is presented in Exhibit G—Water Information. <br /> 6. Schedule of Operations <br /> Mining, screening, and processing will be conducted on site with portable equipment throughout <br /> the year. Product will be sold from these activities throughout the year. The operator will not <br /> typically have night gravel mining operations, although minor truck activity and repairs may <br /> occur after hours. <br /> Lockhart Pit <br /> March 2024 D-4 Lewicki&Associates <br />
