2012 Reclamation Report <br />Southfield Mine <br />During midsummer 2008, the Fremont County Weed Control Agency again sprayed the <br />Knappweed with the appropriate certified herbicide. During 2009, only one Knappweed was <br />identified and EFCI applied Roundup herbicide as prescribed. During 2010, and 2011 neither <br />EFCI nor the DRMS Inspector identified any more Knappweed at the site. During the report <br />period of 2012, apparently the Knappweed had been eradicated. <br />During 2006, Dr. Corley as land owner of the Corley property, sprayed Tamarisk shrubs along <br />the mine entrance road and adjacent to the Magpie Diversion ditch at the east permit boundary. <br />Given that the spraying was executed by the land owner, EFCI does not have information on <br />details of the spraying procedure used. EFCI will continue to inspect these areas and will <br />implement necessary weed control measures consistent with approved management plans. <br />Subsidence Mitigation - Abandoned Canon National Mine site <br />Landowner, The Corley Company, had notified EFCI and the DRMS about six subsidence holes <br />located at the abandoned Canon National mine which is situate on the Corley property. The <br />DRMS determined that EFCI had mined beneath this area and that per EFCI's permit, EFCI was <br />committed to mitigate the subsidence features and the DRMS directed EFCI to submit a <br />mitigation plan. <br />EFCI did so and in October, 2012, contracted with Kessler Reclamation Company to repair the <br />subsidence. Kessler completed the approved mitigation work October 23, 2012. A tracked <br />excavator was used to first remove wood and debris from the subsidence holes. Backfill material <br />was from an abandoned spoils pile adjacent to the subsidence holes that was believed to be from <br />the Canon National mine operations. After trees that had voluntarily grown in the pile had been <br />removed, approximately 700 cu yds of fill material from the pile was backfilled in the subsidence <br />holes. The excavator bucket was used to compact the lower portions of the backfill and a front - <br />end wheel loader was used to compact the upper portions of the backfill. Topsoil from the <br />contractor's property was sampled, analyzed and truck hauled to the site. Five (5) to seven (7) <br />inches of topsoil was spread on the backfilled holes and the footprint of the removed portion of <br />the spoils pile. The approved seed mix was broadcast on the holes and pile footprints as well as <br />the track that was used to access the site. At the landowners request and with the approval of the <br />Division, tree limbs from the tree removal operation were chipped and spread as a mulch on the <br />holes and the pile's footprints. On departure from the site, the barbed wire fence and fence posts <br />were replaced and the No Trespassing sign was reinstalled. Seed mix tags, soil analysis and <br />photos of the operation are included with this submittal. <br />Numerous other concerns of varying subjects were received from landowner Corley Company <br />during the report year. Many of the concerns were addressed by EFCI and the DRMS, other <br />concerns will be addressed prior to approval of the Final Phase 3 Bond Release Request. <br />7 <br />
