ti <br />Marr Mine and Loadout March 23, 2007 <br />2006 Reclamation Report <br />disposal) and limited spraying of scattered occurrences of thistle (primarily Canadian and scotch <br />thistle). Spraying was conducted in 2006 in accordance with the bi-annual spraying schedule. <br />The chemicals used include Tordon and 2-4-D. Mine areas where weed control activities <br />occurred incuded the low areas of the 720 Pit and Pit 1 reclaimed areas, the ridge on the west <br />side of the 720 Pit, the margins of the shop area and along the main access road. Weed control <br />at the Loadout included the railroad right-of-way and in the vicinity of the shop building and the <br />pond embankment. The Jackson County weed control agent confirmed that there was no <br />knapweed found at the Loadout as had been previously reported by the DRMS inspector. Note <br />that Kerr conducted Year 9 and 10 revegetation sampling at the mine in 2005 and 2006. <br />In 2005, Kerr provided additional information pertaining to changing the status of the access <br />road to Pond G and 900 feet of the main mine access road to a permanent light use road. Also, <br />a Permanent Pond demonstration for Pond F was submitted to the DRMS. Approval of these <br />changes is pending. <br />Previously, Kerr has obtained DRMS approval for grazing on the Mine Area. In 2004, 500 head <br />of cattle were grazed for 8 days in July. In 2005 and 2006, the grazing schedule was mod'rfied <br />and due to the year 9 and 10 vegetation study being conducted in the area, there was no <br />grazing. <br />Map 1 (2006 Mine Area Reclamation) presents the general location and extent of site activities <br />completed during 2006 as well as during previous years for the Mine area. Map 2 presents the <br />reclaimed and permanent areas for the Loadout. These activities are described in more detail in <br />the following sections. <br />1.0 MINING AND TOPSOIL REMOVAL <br />Active mining operations at the Marr Mine ceased in January 1993 and no mining or significant <br />topsoil removal activities have occurred subsequent to that date. <br />2.0 BACKFILLING AND REGRADING <br />No backfilling or re-grading was conducted in any new areas at the Marr Mine or Loadout during <br />2005. However, Ponds C and G were backfilled, embankments and spillways removed, <br />regraded and re-seeded in 2006. The estimated reclaimed area is 7.9 acres. <br />3.0 OVERBURDEN STOCKPILES <br />No overburden stockpiles remain at the Marr Mine. The primary overburden stockpile at the <br />Marr Mine was removed and the associated disturbance area reclaimed in 1993-94 in <br />conjunction with reclamation of the 720 Pit. <br />4.0 ROADS <br />In the mine area, the width of both the main haul road and the access road across Bush Draw <br />were reduced in 1995. The remaining road segments are classified as permanent or temporary <br />light-use roads for post-recamation access. No construction or further reclamation work was <br />conducted on permanent or temporary roads during 2004. Due to very limited site activities <br />particularly in the Kerr South Area, there is no need for ongoing road maintenance activities, <br />other than ditch repair and clean-out as needed. Kerr completed some riprap placement in 2 <br />areas along the main access road (mp 0.2 and 0.9) as described in that report. During 2006, <br />63712006l2006annual red rp~ NWCC INC. Paget <br />
