October 20, 2015 C-1981-014/Southfield Mine RDZ Near the truck tunnel, the silt fence is in good shape but the wattles need maintenance. The RDA was inspected from the road/track along the toe, and the southwest corner was walked. The overall vegetation cover is excellent, and there are no erosion features.

At the reclaimed Substation #2 there was no erosion and some emergent vegetation. At the northwest end of the truck tunnel, the shed has been completely removed, and straw mats have been placed on the site for erosion control. The tunnel apron at this end is mostly clear of sediment. No erosion was seen at the Monarch Fan; this area has excellent vegetation cover.
