III. COMMENTS-COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. Reve eta East Wadge slopes below V-Ditch 1 are characterized by patchy stands of well established perennial vegetation intermixed with earlier successional stands dominated by annuals and sweetclover, in areas impacted by past erosion and associated repairs. Upper portions of the slope generally support better stands of desirable perennials, with lower successional stands more prevalent on the lower slopes. With the apparently successful erosion control implemented following approval of TR-41, successional processes would be expected to result in increased cover and composition of desirable perennials. However, due to the history of repeated disturbance on the East Wadge slopes, there is a significant presence of noxious weeds including Canada thistle, hounds-tongue, and whitetop, particularly on lower slope areas along and east of PM-8, within erosion repair areas, and along V-Ditches. Focused weed control efforts will need to be continued. In some of the roughened gully repair locations, there is a significant component of shrubs,but noxious species are also present. Care will be necessary when spraying these weed patches to minimize loss of desirable shrubs. In the Solid Waste Disposal Area, initial establishment in the 1st and 2nd year seeding looks quite good. Species diversity and density of seedling sagebrush was notable in the 2nd year seeding on the west facing hillslopes. A few patches of Canada thistle were noted, mostly adjacent to the South Road in the landfill vicinity. Some patches of Canada thistle and houndstongue were also noted along Channel PM-12A. Phase 1 Bond Release Reclamation Success Summary Based on site inspection, the reclaimed areas within the SL-4 bond release request parcels (delineated on SL-4 Map Exhibit A) appear to have been restored to the approximate original contour of the pre-mining landscape. Slopes are in general conformance with approved post- mining contours as shown on Postmining Topography and Permanent Features Map of the approved permit(Exhibit 13-2A) and on Exhibit E of the Phase I bond release application, and appear to be stable. Reconstructed drainages within the release request parcels are in good condition, with only minor exceptions along a couple channel segments where repairs are necessary(as noted previously in the report). One discrepancy between approved and existing drainage alignment was noted in regard to PM_I2A, which will require revision of the permit(as discussed previously in the report). 10
