2013 Annual Reclamation Report Southfield Mine growth. Although the fall season of 2010 had little rainfall, spring moisture and monsoon rains proved well for the vegetation. Reports by the Division (2011) state that the vegetation on the sites continue to do well and that the successful results are serving as an effective erosion control as well. The winter season of 2011 yielded very little snow melt and precipitation during 2012 was also very low. Although moisture was low, on the non - sloping sites, the vegetation appeared stunted but maintained sufficiently to serve adequately for erosion control. The southwest slope of the Refuge Disposal Area (RDA) did not fare as well during the summer season of 2012. Grasses were short and sparse on the south slope area but sufficient to curtail erosion on the slope. Only slight rilletts were noticeable on the south slope. The Loadout Area was seeded to the permanent revegetation seed mixture in 1997. Poor initial vegetative establishment resulted in the decision to reseed the entire Loadout Area in 1999. Limited topsoil availability and extended drought conditions had hindered effective vegetative reestablishment in the Loadout Area. Through ongoing discussions with the DRMS, limited interseeding (25 percent of area) of the reclaimed Loadout area was approved by the DMG (DRMS), with the understanding that this limited work would not affect the current liability schedule (10 -year liability period initiated by secondary reseeding in 1999). During March of 2011, due to trespassers entering both Loadout sites at each end, a trench with berm was cut across each of the trespasser's entry points. During the report periods of 2012 and 2013, the trenches have served as an effective deterrent to trespasser vehicles at those entry points. IME, Inc., sample /monitored the Loadout site during the summer season of 2006. Results of data obtained from the monitoring is included in the Revegetation Monitoring Report for Reclaimed Areas in the section titled "Loadout Reclamation ". IME, Inc. also sampled the Loadout during 2010 and again in 2013 for the Year 9 vegetation monitoring requirement. EFCI has revegetated a cumulative total of approximately 82.6 acres at the Mine Site and Loadout areas as shown on the attached Annual Reclamation Report form. Maps accompanying this report show all revegetated areas, with the exception of approximately 1.5 acres of minor road segments revegetated in 2003 at the North Well (a.k.a. MW -NW) and the Corley Well areas. The previously revegetated areas are shown on Map 1, Mine Site Reclamation; Map 2, Ancillary Facility Areas Reclamation and Map 3, Loadout Area Reclamation. As previously stated, during 2006, Mr. Kent Crofts of I.M.E. , Inc., did the interim revegetation sampling and reporting at the mine site, the refuse pile area and at the Loadout site. Map 1 shows areas of the contemporaneous reclamation plots listing progressive dates of seeding and the approximate acreage of each plot. 0
