HYDROLOGIC BALANCE -continued Seeps and Springs RSP 2 and 3 are flowing a trickle of clear water. RSP 4 is flowing more than 2 gpm of clear water. TOPSOIL The only topsoil stockpile remaining in the permit, pile C, is well-vegetated. REVEGETATION The areas where ponds 001 and 002 were reclaimed have been seeded, fertilized, and mulched with hay. Both areas are dry and have little new growth. The area of 001 has abundant lupines growing. The area of 001 has a large patch of Canadian thistle growing. Dozer tracks leading to these reclaimed ponds are not evident due to thick grasses. There is considerable activity by the operator in the three fenced shrub transplant areas around pond 003, around pond HG-t3, and the (former) pit area. Plants are furthest along around the two ponds. Shrub development in the pit area suffered a setback this season by the operator's need to replace (in midseason) white fabric mulch with black fabric mulch. The original white fabric that was installed early this season did not control weed growth due to its color and large holes cut in it for plants. SLIDES AND DAMAGE Slump in Southeastern Portion of Reclaimed Pit Area Misalignment of the markers (steel posts) on the slump was first reported in the Division's inspection on October 10, 1996. Of the 10 markers on the slump, only the eight westernmost markers remain in alignment. The marker 2nd from the east end lies approximately 6 inches uphill from the 8 aligned markers; the marker on the east end lies approximately 1 foot uphill from the 8 markers. It appears that the area of the 8 aligned markers has slipped as a unit downhill relative to the 2 markers on the eastern end. The tops of the 8 markers appear slightly rotated into the hillside. The progressive eastward increase in offset among the 3 markers on the east end indicates drag on the eastern margin of the slump block. What appear to be tension cracks are in the soil in a depression at the top of the slump. One crack extends more than 100 feet across the top of the slump. The ground surface of the slump is well-vegetated. Mike Neumann, representing the operator on the site, acknowledges the markers indicate downslope movement of the slump. He suggests that two consecutive wet spring seasons and a possible malfunction in the the french drain above the slump could be the cause of the recent movement. He recalls the perforated pvc pipe in the french drain may have been covered with rock that was coarser than called for in the design specification. He suggests this coarse material may have allowed fine- grained material to migrate into the drain resulting in water accumulating in the drain rather than passing through it. Neumann says he is considering installing piezometers on the slump to monitor water accumulation in the slump. The piezometers would be installed in holes drilled with a power auger in order to reduce ground disturbance. Mike is also considering digging ditches at the top of the slump to direct water away from the slump. David Berry says breaking the ground by digging ditches would probably reset the clock on bond release, but the piezometer installation would be beneficial and would not interrupt the bond release clock if a power auger is used to minimize surface disturbance. He recommends that the operator conduct a formal monitoring program to detect any future changes in marker alignment. -4-
