Encountered, indicates the principle composition of the seed mix used in reseeding. Other species observed included squirreltail, western wheatgrass and native and Kentucky bluegrass. Numerous weedy species including gumweed, thistle (Cirsium species) and knotweed (Polygonum sp.) were present. Livestock grazing has been heavy in this type. DHG — Revegetated Hayden Gulch Disturbances. All revegetated disturbances associated with construction of the loadout facility, rail loop and rail spur (70.8 acres) are included in this type. The loadout facilities and access road to the southwest are not included. With the exception of the railroad ballast, all areas have been revegetated with a permanent stabilization mix. Species observed in the revegetated areas include intermediate wheatgrass, Russian wildrye (Elymus junceus), crested wheatgrass, western wheatgrass, slender wheatgrass, timothy, alfalfa (Medicago sativa) and yellow sweetclover (Melitotus officinale). Weedy species common in the reseeded cropland areas are also present in the revegetated areas. This type has also been heavily grazed. FHG — Hayden Gulch Loadout Facilities. All loadout facilities and access roads, excluding the rail loop and spur, are included in this area (17.8 acres). Areas not under roads, structures or stockpiles have been seeded with a temporary stabilization seed mix similar to that used in the DHG type. TS — Topsoil Stockpiles 1 -3. Two topsoil stockpiles are located within the rail loop and one is located along the access road southwest of the loadout area. Another six topsoil stockpiles are located along the haul road corridor. All stockpiles have been seeded with a mix similar to that used in the DHG type. The stockpiles are stable and have no erosional problems. Tie - Across Haul Road Corridor. This haul road corridor was transferred from Seneca II- W permit to the Hayden Gulch Loadout permit in 2011. The total area included in the corridor is 213.5 acres. The vegetation communities within the haul road corridor and associated acres are as follows: Veg Type Acres % of Area • Existing roads 3.0 ac 1.4% • Water or Ponds 0.1 ac 0.1% • Disturbed land 7.0 ac 3.3% • Low sagebrush 40.4 ac 18.8% • Wheat Cropland 124.2 ac 57.9% • Meadow 14.1 ac 6.6% • Greasewood 11.3 ac 5.3% • Mtn. Big Sagebrush 4.6 ac 2.1% • Disturbed Meadow 7.6 ac 3.5% • Disturbed riparian 2.2 ac 1.0% Other Cate ones. Remaining portions of the permit area include sediment ponds (PS -1.2 acres), County and U.S. roads (RD —1.2 acres) and the Walker Ditch. PR -01 5 Revised 07/11
