5. Revegetation Plan <br /> Each mine area will be reseeded once that area is retopsoiled. Prior to seeding, the soil may be <br /> disked to loosen surficial soils. Due to the mild grade, seed can be drilled in most areas, but <br /> broadcast seeding will be utilized where reclaimed perimeter slopes do not allow drilling. <br /> Broadcast seeding will be done at double the drill rate. <br /> The seed mix listed below will be used to revegetate the site with a native grass mix on all <br /> surfaces. This seed mix was recently reviewed and accepted in December 2020 by the NRCS to <br /> revegetation of dry rangeland areas. Certified weed free mulch may be crimped into the surface <br /> at 2000 lbs. per acre. Fertilizer may be added as determined by a soil test at the time of seeding. <br /> Heavy furrows will be left in the tilled topsoil to provide moisture concentration and shade areas <br /> in order to promote better conditions for successful vegetation establishment. Seeding will take <br /> place during the fall following retopsoiling of slopes. Slopes will be regraded, and retopsoiled as <br /> soon as they are able to be reclaimed and as additional mining areas become active. <br /> 5.1 Native Grass Seed Mix <br /> Species Pounds of pure live seed per acre (drilled) <br /> Blue grama 1.8 <br /> Western wheatgrass 9.6 <br /> Sideoat-, grama 1.8 <br /> Needle and thread 2.2 <br /> Indian ricegrass 1.2 <br /> Little bluestem 0.7 <br /> Galleta grass 0.4 <br /> Green needlegrass 1.0 <br /> Total 18.7 <br /> 6. Post-Reclamation Site Drainage <br /> Map E-3 shows arrows indicating the approximate direction of drainage throughout the site. <br /> Final reclamation surfaces will be graded such that onsite drainage waters flow in a similar path <br /> to the original pre-mining path; however,the majority of surface water will infiltrate the porous <br /> Bancroft Placer Mine I;nV I rmttu and A/Wriswo.waa <br /> July 2020 D-2 <br />
