October 15, 2010 C-1981-020/Munger Canyon Mine DTM <br />Waste Disposal and Adjacent Areas <br />The waste disposal area itself, the immediately adjacent soil stockpile site, and the lower road topsoil stockpile <br />reclaimed site, located further down the permanent road were also revegetated in 2007. In contrast to the <br />backfilled road and portal areas, seeding appears to have been unsuccessful in these locations, with continued <br />heavy dominance by weedy annuals, primarily Russian thistle and cheatgrass, with some Kochia and other annual <br />broadleafs. Scattered patches of big sagebush and winterfat are present, but perennial grasses and forbs are largely <br />missing from the stands. Weed control and re-seeding would appear to be warranted at these sites. Appropriate <br />treatment might include tillage or glyphosate application early next spring to target Russian thistle and Kochia <br />seedlings, as well as cheatgrass, followed by a subsequent spray application in the fall of 2011 for fall germinating <br />cheatgrass, with dormant seeding of the perennial seedmix in late October or November. If the site is broadcast <br />seeded, the plan would need to include method for soil scarification/seed coverage. A minor revision application <br />addressing the reseeding plan should be submitted to the Division for approval well prior to initiation of treatment. <br />Consultation with county weed control authorities for their recommendation regarding treatment and timing <br />approaches, and herbicide application rates best suited to the combination of annual brome, Russian thistle, and <br />Kochia control prior to perennial seeding is advised. The edges of the road that were scarified and seeded in 2007 <br />are also heavily dominated by annual weedy species from the upper end down through the waste disposal facility, <br />and the roadsides along this segment should also be treated and re-seeded. <br />OFFSITE SUPPORT FACILIITES - Rule 4.04, 4.28: <br />The reclaimed Loma Loadout site was inspected. The site is erosionally stable, with a vegetative cover comprised <br />of seeded shrubs, subshrubs, and grasses, along with volunteer annual species. Cover appears to be comparable to <br />adjacent areas to the south of the reclaimed site. The silt fence was still intact and functional, but is becoming <br />worn and should be replaced. <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: 2 <br />Page 5 of 10
