EXHIBIT D RECLAMATION PLAN 1. General Reclamation Plan The maximum disturbed area to be reclaimed under this permit is —20.0 acres out of the 30.0 acre permit area. Reclamation plans can be viewed on the Reclamation Map. Post-mining land use will return the entire disturbed site back to dry rangeland with native grasses on all slopes and is consistent with existing land use in the area. All slopes will be reclaimed to 3H:1 V or shallower. As described in the mining plan,reclamation will occur concurrently with mining. The pit ramp will be left in place to allow for vehicle access to the bottom of the site during grazing use. 2. Topsoil Replacement Topsoil on site is anticipated to range from 0-6 inches thick. During mining, all topsoil will be stored in the site perimeter berm along the north, south, west, east borders of the site and are shown on the Reclamation Map. Topsoil will be replaced over the entire mine site in one event due to the small size of the site. Topsoil thickness upon replacement is expected to be 3 inches thick on average. 3. Haul Roads and Access Three access entrances and roads will connect the site to County Road T. Onsite haul roads will be flexible as mining moves throughout the site. See the Reclamation Map for the layout of roads after mining and reclamation. 4. Reclamation Timetable See Exhibit E section 2. 5. Revegetation Plan For each area of reclamation, soil may be disked to loosen surficial soils. Due to the mild grade, seed can be drilled in most areas, but broadcast seeding will be utilized where reclaimed perimeter slopes do not allow drilling. The seed mix listed below will be used to revegetate the site with a native grass mix on all surfaces. This seed mix was recently reviewed and accepted in December 2019 by the NRCS to revegetation of dry rangeland areas. Certified weed free mulch
