Marc Mine February 22, 2005 2004`Reciamation Report Loadout area..EFCI obtained DMG approval for grazing on the mine area. 500 head of cattle were grazed for 8 days in July, from July 10 to July 18, 2004. Map 1 (2004 Reclamation Map) presents the general location and extent of site activities completed during 2004 as well as during previous years. These activities are described in more detail in the following sections. 1.0 MINING AND TOPSOIL REMOVAL Active mining operations at the Marr Mine ceased in January 1993 and no mining or significant topsoil removal activities have occurred subsequent to that date. 2.0 BACKFILLING AND REGRADING No backfilling or re-grading was conducted in new areas at the Man- Mine or Loadout during 2004. 3.0 OVERBURDEN STOCKPILES The primary overburden stockpile at the Marr Mine was removed and the associated disturbance area reclaimed in 1993-94 in conjunction with reclamation of the 720 Pit. No overburden stockpiles remain at the Marr Mine. 4.0 ROADS In the mine area, the width of both the main haul road and the access road across Bush Draw were reduced in 1995. The remaining road segments are dass~ed as permanent or temporary light-use roads for post-reclamation access. No construction or further reclamation work was conducted on permanent or temporary roads during 2004. Due to very limited site activities particularly in the Kerr South Area, there is no need for ongoing road maintenance activities, other than ditch repair and clean-out as needed. 5.0 TOPSOILING AND REVEGETATION Topsoiling and mulch seeding was conducted in 1999 on approximately 6.5 acres within the Mine Area including the designated disposal area on the southeast edge of the shop/warehouse facilities pad and the former powder magazine area, soil stockpile area, and associated road. These areas were seeded in 2000 by inter-seeding the permanent seed mix (Table 67A) into the standing mulch. The application rate was at the prescribed rate for both grasses (11.5 pounds per acre) and shrubs and forts (5.75 pounds per acres). Four small areas were inter- seeded during 2003 to enhance vegetative growth including the southwest comer of the Pit 1 area, the north end of the Marr Pit area, the ridge to the west of the Marr Pit area, and the north slope of Pond A. 6.0 NOXIOUS WEED CONTROL All areas were inspected during spring 2004. Minor occurrences of thistle were hand dug and destroyed whenever they were observed while conducting other field efforts. Spraying for thistle was conducted on September17 and 18, 2004 in the same areas of concern monitored in recent years as listed below: sa»rzona ~~~i ~ r~caoc NWCC INC. Page 2
