1 <br /> III. COMMENTS - COMPLIANCE <br /> Below are comments on the inspection. The comments include discussion of observations made <br /> during the inspection. Comments also describe any enforcement actions taken during the inspection <br /> and the facts or evidence supporting the enforcement action. <br /> Revegetation and Reclamation Success <br /> Areas disturbed in association with the recent stabilization project were hand roughened and seeded <br /> with the following seed mix: <br /> Species Variety PLS Pounds per Acre <br /> Rubber rabbitbrush(Chrysothamnus nauseousus) 0.2 <br /> Fourwing saltbush(Atriplex canescens) Rincon 4.0 <br /> Shadscale saltbush(Atriplex confertifolia) 4.0 <br /> Western wheatgrass(Agropyron smithii) Arriba 6.0 <br /> Indian ricegrass(Oryzopsis hymenoides) Paloma 3_0 <br /> 17.2 <br /> Total <br /> Portions of the mine site were originally revegetated in the 1990's, and a significant acreage at the site <br /> was reseeded in association with a DBMS bond forfeiture reclamation project in 2000, following <br /> extensive flood damage in 1998. A relatively minor acreage was seeded in association with DBMS <br /> remedial projects in 2009, including the small (+/- '/2 acre) portion of the Mine #2 portal backfill, where <br /> established vegetation was limited to scattered shrubs, with poor understory. As described in <br /> previous reports, there is good establishment of seeded shrubs in most reclaimed areas, and good <br /> establishment of both seeded grasses and shrubs along the reclaimed access road to the upper <br /> bench. Vegetative cover on reclaimed slopes appears to be effective in minimizing erosion associated <br /> with rainfall at the site. Erosion that has been observed in recent years is almost entirely due to <br /> concentrated runoff from areas upstream of the mine site. Repair and minimization of channel erosion <br /> from concentrated upland flow has been the focus of remedial measures in 2009; along with closure of <br /> a small opening in the Mine #1 portal backfill, sealing of a non-functional culvert spillway at the <br /> sediment pond and improvement of the open channel spillway. The work undertaken in 2009 utilized <br /> all remaining reclamation funds, and appears to have adequately addressed the various watershed <br /> and safety concerns that had been identified. <br /> 4 <br />
