There were no observed <br />eros ional issues. The channels did not have segments that were observed to have down cut or have had channel <br />abandonment occur. <br /> <br />The reclaimed pond (Photo 2) and topsoil stockpile foot print area (Photo 3) were both stable and had well <br />established vegetation providing sediment control. No off -site impacts were observed. <br /> <br />Both Munger and Monger Creek were observed to be dry during the inspection. <br /> <br />For more details on the hydrologic balance of the Munger Canyon Mine please see the Reclamation Success <br />section of this report. <br /> <br />ROADS – Rule 4.03 <br />Cons truction 4.03.1(3)/4.03.2(3) <br />Drainage 4.03.1(4)/4.03.2(4) <br />Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) <br />Reclamation 4.03.1(7)/4.03.2(7): <br /> The access road to the site has been approved to remain on site to support the post mining land use. The <br />road is 1.2 acres in size. During the inspection the road was in good repair. There were no concerns identified <br />with regard to stability or erosion. <br /> <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br /> There are 3 creek crossings at the mine site where the access road crosses Munger Creek. These crossings <br />had the CMPs removed and the access road was graded to meet the level of the creek to allow for water to flow <br />freely. These areas were in good repair and the evidence of recent flows showed that the cross ings were stable. <br /> <br />The sediment pond and was regraded and seeded in 2014. The vegetation has established well at the site and was <br />similar to the surrounding areas. Erosion from the reclaimed site has been sufficiently controlled. The site had no <br />indic ations of instability. The topsoil pile to the north of the reclaimed sediment pond was used during the final <br />reclamation of the pond. The pile foot print was seeded in 2014. Vegetation has become well established at the <br />site. The vegetative cover is s imilar to the surrounding area and is sufficient to control erosion. Both the <br />sediment pond and topsoil pile footprint meet the requirements of Rule 3.03.1(5). <br /> <br />The haul road (Photo 4) was regraded and seeded in 2007. The regraded areas blend well wit h the surrounding <br />topography. The surface was left very well roughened. Vegetation has become well established on the reclaimed <br />road. There were no areas identified with erosional concerns. The rock lined channels along the haul road were in <br />good condition and capable of functioning as designed. There were no blockages or erosional issues located in the <br />channels. <br />
