expansion was done consistent with existing approved practices for sloping and <br />construction methods. This expanded area added 3.2 Acres to the WRSF. The new <br />area remains within the previously disturbed area and does not add any additional <br />acreage to the 60 acres of permitted disturbed area. The topsoil stockpile has been <br />protected with Silt Fence and will be seeded at the appropriate time this fall to <br />accommodate sprouting of the approved Seed mixture in the spring of 2014. (Refer to <br />Figure 10 and 11 attached) <br />In addition to the above -noted items, the work permitted under TR -19 and TR -20 last <br />year has been completed. The Fabric - covered structure to house the Shot Crete <br />batching equipment and the concrete slabs associated with the building are complete. <br />The Core Logging facility and associated pad and retaining wall work has been <br />completed. RGS also constructed a cover over the fuel containment at the Bulldog Mine <br />site. The cover involved setting a concrete footing for the containment to be bolted into <br />and then covering the containment with a single - sloped roof. This structure is designed <br />to prevent snow and rain from entering the containment. This work is all complete. <br />In addition to these new disturbed areas, there was one other action taken this year on <br />the permit. It is as follows: <br />Revision # AM -1 /Amendment #1 to Permit # M1977 -215 approved July 12, 2013 <br />which included the addition of permitted acreage for future mining - related activities. This <br />action raised the total permitted acreage to 568.0, but did not change the approved <br />affected area of 60.0 acres. (Refer to Figure 14 attached) <br />Reclamation <br />Reclamation of the slope below the New Core Shed referenced above and permitted <br />under TR -20 was completed in June 2013 along with the installation of straw waddles to <br />prevent any slope erosion. This area has achieved stabilization and exceeds 70% of <br />pre- disturbance status. <br />The area where work was completed at the Vent Raise was re- seeded in July 2013 <br />along with the Topsoil Stockpile for same area immediately upon completion of the <br />project. The City Water Line disturbed area was also seeded immediately upon <br />completion of the pipe installation and backfill. The timing of the re- seeding in these <br />areas coincided with the beginning of the monsoon season, which allowed excellent <br />sprouting and growth of the placed seed product. The areas achieved at least a 70% <br />growth rate as compared to pre- disturbed status. These areas will be seeded again just <br />before the next anticipated snowfall to assure that the seed will sprout in the spring. <br />(Refer to Figures 9, 15, 16, 17, and 18 attached) <br />In August, 2013, disturbed ground immediately adjacent to the 9400 portal road, the <br />area below the upper waste rock storage facility(including the Stockpile of topsoil for <br />future reclamation) were seeded and waddles with silt fence installed as double <br />protection from erosion. Additionally, the area surrounding the southern holding pond <br />was also re- seeded. Re- seeding was conducted by RGS personnel by method of hand- <br />112 East 12t" Street P.O Box 610 Creede, CO 81130 <br />719 -658 -1 080 Fax 719 -658 -1082 <br />
