June 18, 2014 C- 1981 - 014 /Southfield Mine RDZ <br />At the RDA, no problems were seen with diversion ditches. <br />The portion of Newlin Creek where a landowner has indicated that there is a losing reach due to subsidence was <br />inspected for cracks or other indications of mining impacts. No impacts were seen. There was not enough soil <br />moisture for the inspector to look for losses in the creek. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />The perimeter of the RDA was driven; no rills were seen. On the east side of the RDA significant cheat grass was <br />seen, and a small number of thistle plants were seen near the northwest corner of this area. <br />ROADS — Rule 4.03 <br />Construction 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 />Roads to the facilities area and the RDA were in acceptable shape. The ditch along the entrance road to the portal <br />area has eroded but does not appear to be threatening the stability of the road. The road to the Monarch Mine is <br />still passable but is narrow in areas due to erosion. Along the road to the Monarch Mine, the downdrain structures <br />( "socks ") were found to be in acceptable shape, and no problems with culverts were seen. One of the "socks" <br />requires maintenance: the second one from the portal area is partially buried under soil and should be dug out. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />The portal area, including the area around the truck tunnel, was in good shape; no erosion or large weed patches <br />were observed. However, cheat grass was observed near the gravel lot. Also, the Pond 3 reclamation area and the <br />rock dust storage SAE were inspected and no problems were seen. <br />The area near Newlin Creek where subsidence cracks were repaired and an historical topsoil pile was used to fill <br />the holes (upstream of the Thompson driveway) has seen moderate success with re- vegetation. Bare spots and <br />weeds (cheat grass, Mullen, cranesbill) are still present. <br />SUBSIDENCE — Rule 4.20: <br />The area near Newlin Creek where subsidence cracks were repaired was inspected. No new cracks were seen. <br />SUPPORT FACILITIES - Rule 4.04: <br />The Monarch fan area was inspected and no problems were seen. The vegetation on the hillside looks good. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 5 <br />Page 3 of 11 <br />
