Topsoil will continue to be <br /> stripped at an 8 to 12-inch depth. If topsoil stockpiles exist in a non-commercial state for <br /> more than one growing season, then they will be sloped to 3:1 V or flatter and seeded with <br /> a fast-growing vegetative cover, per the approved permit. <br /> During the Final Phase,the residential area will remain at its current location at the southern <br /> end of the site (Figure 3). This area includes a residential house, garage, carport, chain- <br /> link fence, rock bins and stockpile materials. The residential area is part of the requested <br /> TR-2 as an approved PMLU (see next section). <br /> The eastern edge of the existing pond will remain as recreational beach area (Figure 3). <br /> The recreational area includes a sandy beach, trees, a small dock, gravel boat ramp, a few <br /> small cabins, a fire pit, picnic area, a playground, wooden fencing, and artistic structures. <br /> The recreational area covers approximately, 0.3-acre. The recreational area is part of the <br /> requested TR-2 as an approved PMLU (see next section). <br /> Updated Post Mining Land Use and Reclamation Plan <br /> Reclamation will be continuous throughout the Final Phase mining process. As more <br /> shoreline is created and expanding of the pond progresses, topsoil will be replaced, at a <br /> depth of 12-inches, along banks. The topsoil will be seeded with the approved seed mix, <br /> as soon as practical (late fall or early spring). The banks will be graded a minimum 3H:1 V <br /> slope from 5 feet above to 10 feet below expected water line. Shorelines and banks will <br /> be stabilized with boulders, cobblestones, and/or concrete riprap as needed to prevent <br /> erosion. <br /> Bivens requests to reclaim the processing and recycling area as a RV parking/recreational <br /> area (Figure 4). This 1.3-acre area will be either covered with 6-inches of road base <br /> material that is stored on site (if a parking lot), or excavated for a water feature. If <br /> reclaimed as a parking lot, road base will be spread evenly and graded drain to the pond at <br /> an approximate 1% slope. All the road base material will come from existing material <br /> stockpiles onsite. At a minimum, 1,050 cy of road base material will be required to cover <br /> the parking lot and remain onsite to be used for this reclamation. If excavated for a water <br /> feature, Bivens will place the excavated inter material in the Final Phase mine pit. <br /> The disturbed perimeter area,around the 1.3-acre parking lot or water feature,will be tilled, <br /> graded, retopsoiled at a depth of approximately, 12 inches, and revegetated with the <br /> approved reclamation grass seed mix (switchgrass, slender, wheatgrass, tall wheatgrass, <br /> alkali sacaton, yellow sweet clover) (Figure 4). <br /> 20201222_Birens Pit_TR_Response Letter 2020_Final T E L E S T o <br />
