August 1, 2014 C- 1981 - 014 /Southfield Mine RDZ <br />to Map 12. The coordinates recorded by Rob Zuber (in NAD83) are: <br />105 deg, 9' 51.98" W and 38 deg, 17' 24.32" N. <br />At the loadout, ponds L -1 and L -2 were dry at the time of their inspection, prior to the heavy rain. No major <br />problems were found with embankments, flumes, or spillways. Significant riparian vegetation was seen in the <br />bottom of Pond L2. The Pond L1 primary spillway contains approximately 5 inches of sediment and should be <br />monitored. <br />A hole in the Magpie Creek bed was seen south of Substation #2. It is approximately two feet in diameter. The <br />water in the creek, in response to the heavy rain, was flowing at approximately 200 to 250 gpm upstream of the <br />hole, and nearly all of this flow was disappearing into the hole in the creek bed. The flow was estimated by <br />visually estimating the amount of gallons per second entering the hole. Mr. Weaver indicated that there may have <br />been documentation of this issue in an Annual Hydrology Report (AHR) from many years ago. DRMS is studying <br />this issue and will research the old AHR. This issue may be related to the subsidence holes noted in the <br />Subsidence section of this report; the hole in the creek is not more than 300 feet from these other holes. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />At the loadout, no large bare spots, erosion, or weed patches were seen. <br />SUBSIDENCE — Rule 4.20: <br />The area south of Substation #2 where subsidence cracks may need to be repaired was inspected. Three <br />significant holes were seen, which are all very close to each other (within approximately 200 feet), and other small <br />holes are nearby. DRMS will prepare a separate report regarding this potential subsidence, including a map <br />created using GPS data. The holes were flagged with orange tape, and the following details were recorded. <br />• The southern hole is approximately 12 feet by 14 feet and approximately 7 feet deep. <br />• The eastern hole is approximately 9 feet by 13 feet and approximately 3 feet deep. <br />• The western hole is approximately 18 feet by 10 feet and at least 15 feet deep. <br />OFFSITE SUPPORT FACILIITES - Rule 4.04,4.28: <br />Trash is still present at the loadout, including a box spring below pond L -2, a pile of concrete rubble, trash <br />near Pond L2, and trash near the fence by the road. See Hydrology section for discussion of ponds at the loadout. <br />The rest of the loadout area was inspected, and no erosion weed patches, or other problems were seen. <br />DOCUMENTS RECEIVED <br />2013 AHR, Revisions for MR -63, MR -64 application <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 3 of 6 <br />
