5. Revegetation Plan <br /> Prior to seeding,the soil may be disked(where not laden with small cobble)to loosen surficial <br /> soils. Due to the mild grade, seed can be drilled in most areas, but broadcast seeding will be <br /> utilized where reclaimed perimeter slopes do not allow drilling. Broadcast seeding will be done <br /> 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 used successfully at the use at Weimer No.2 Mine(DRMS permit <br /> M-1996-031) for revegetation of dry rangeland areas. The Weimer No. 2 Mine is located <br /> approximately 500 feet east of the Weimer Ranches#4 Mine at a similar elevation,with similar <br /> soil and water conditions. The Division approved the full surety release for the Weimer No. 2 <br /> Mine on January 11,2021, indicating the seed mix performed well. The seed mix recommended <br /> for use at the Weimer No. 2 Mine would be expected to also perform well at the Weimer <br /> Ranches#4 Mine. <br /> Fertilizer may be added as determined by a soil test at the time of seeding. Heavy furrows will <br /> be left in the tilled topsoil to provide moisture concentration and shade areas in order to promote <br /> better conditions for successful vegetation establishment. Seeding will take place during the fall <br /> following retopsoiling of slopes. Slopes will be regraded, and retopsoiled as soon as they are able <br /> to be reclaimed and as additional mining areas become active. <br /> Native Grass Seed Mix <br /> Species Pounds of pure live seed per acre(drilled) <br /> Blue grama 0.4 <br /> Indian Ricegrass 2.0 <br /> Buffalograss 12.0 <br /> Western Wheatgrass 4.0 <br /> Total 18.4 <br /> Weimer Ranches #4 C.%1—klu and A�i&"MAA <br /> June 2021 D-2 <br />
