Marr Mine and Loadouf March 23, 2007 <br />2006 Reclamation Report <br />the entrance road was bladed from the shop area to the main entrance gate and the road ditch <br />was maintained where needed. Additional contour furrows were installed on the east facing <br />slope directly west of the shop facilities to control rill forming and run off on the slope. The new <br />furrows were hand inter-seeded with the approved penmanent seed mix. <br />In 2005 Kerr requested that the temporary light use road status be changed to permanent for <br />the Pond G access road and 900 feet of the mine access extending from CR12E. Road <br />permanence is pending approval from the DRMS. <br />5.0 TOPSOILING AND REVEGETATION <br />Ponds C and G, their associated soil stock piles and ditches were reclaimed in September 2006 <br />(7.9 acres). The seed mixture was consistent with the approved permanent seed mix and was <br />drill-seeded at the prescribed rate. Seed mixture documentation is provided in Attachment A. <br />There were no activities in 2004 or 2005 associated with the top soiling or revegetation. Top <br />soiling and mulch seeding was conducted in 1999 on approximately 6.5 acres within the Mine <br />Area inGuding the designated disposal area on the southeast edge of the shop/warehouse <br />facilities pad and the former powder magazine area, soil stockpile area, and associated road. <br />These areas were seeded in 2000 by inter-seeding the permanent seed mix (Table 67A) into <br />the standing mulch. The application rate was at the prescribed rate for both grasses (11.5 <br />pounds per acre) and shrubs and (orbs (5.75 pounds per acres). Four small areas were inter- <br />seeded during 2001, 2002 and/or 2003 to enhance vegetative growth including the southwest <br />comer of the Pit 1 area, the north end of the Marr Pit area, the ridge to the west of the Marr Pit <br />area (north end) and the slope northwest of Pond A. <br />6.0 NOXIOUS WEED CONTROL <br />All areas were inspected and weed control spraying completed in 2006. Spraying for thistle was <br />conducted in the same areas of concern monitored in recent years as listed below. The <br />chemicals used include Milestone (Aminophyralid) and 2-4-D to control occurrences of thistle <br />(primarily Canadian and scotch thistle). <br />Mine Area <br />• Bottom of the 720 Pit and Pit 1 reclaimed areas <br />• The ridge on the west side of the 720 Pit <br />• The margins of the mine shop area <br />• Along the main access road <br />Loadouf Area <br />• Along the railroad right-of-way <br />• The vicinity of the shop building <br />Pond Embankment <br />In 2004 and 2005, minor occurrences of thistle were hand dug and destroyed whenever they <br />were observed while conducting other field activities. <br />7.0 DRAINAGE AND SEDIMENT CONTROL <br />Kerr conducts regular routine inspection and maintenance for all ponds, ditches and other <br />drainage and sediment control structures.
