This reclamation is not part of Munger Canyon Mine's SL -2. GW monitoring holes near the sediment pond have not yet been reclaimed. REVEGETATION — Rule 4.15 Vegetative Cover; Timing: Vegetation on the reclaimed haul road was very good with well established shrubs, sagebrush, and diverse grasses and forbs. The reclaimed haul road and portal bench exhibited good cover, and appeared stable. Although late in the season, there were no obvious standing stalks of noxious species, i.e. thistles, knapweeds, or other identifiable noxious species. Cheatgrass is present in the lower elevation areas of the access road. Cheatgrass is a List C noxious weed and does contribute allowable cover to the success standard. As a list C species, eradication of cheatgrass is not required. (State Dept. of Agriculture Noxious Weed Act) OFFSITE SUPPORT FACILIITES - Rule 4.04,4.28: The Loma Loadout is a reclaimed train loadout with an approved industrial post - mining land use. The loadout has been regraded with a gentle slope to the southwest, and a berm on the southwest permit boundary. No topsoil stockpiles were present on the site. Vegetation on the loadout consists predominately of 4 -wing saltbush, forage kochia and perennial grasses. Cover is fair, with open spaces between the perennial ground cover. There was no sign of rill or gully formation or sediment deposition on the down slope side of the property.
