Active mining and related activity was suspended and final reclamation adivities were initiated in early 1993. Final reclamation of most mine disturbance areas was completed during the period from 1993 through 1996. Disturbance areas recaimed in 1999 included the Loadout Area, a portion of the shop/warehouse facilities pad and the former powder magazine area, soil stockpile area and associated road. Approximately 357 acres have been reclaimed in the Marr Mine and Loadout areas, with approximately 44 acres of roads, facilities, sediment control structures, and soil stockpiles remaining. A portion of the remaining total acreage is associated with long-term facilities that have been approved for permanent retention in conjunction with the post-mining land use. Ker relinquished the federal coal lease for the northern portion of the mine property (north of County Road 12E) in July of 2002. All areas reclaimed in 1999, except the Loadout Area were initially seeded to the annual rye mulch crop followed by the permanent revegetation seeding in 2000. The Loadout Area was seeded to the permanent revegetation seed mixture. Areas identified during the 2001 bond release inspections as presenting erosion or revegetation concems were repaired and reseeded to control erosion (in 2001). Inspection of these areas in early 2002 indicated limited vegetative growth, so additional seed was inter-seeded into the existing vegetation (in 2002 and 2003). No reclamation work (maintenance or repairs) was required or conducted in 2004. As part of Ker's regular site maintenance adivities, surface water control structures were inspected. Any concems noted by the Division of Minerals and Geology (DMG) in their regular site inspection reports were considered. Based on inspection, the surface water control structures were generally in good condition. The only required repairs or maintenance adivities are noted below. The DMG identified minor erosion in the PD-1 and PD-3 drainage channels. Kerr inspected these areas and determined that no immediate maintenance was required. Monitoring and maintenance in these areas will continue. Aggressive noxious weed control measures were implemented in 2000 in several areas to control and eliminate localized weed infestations. These areas are indicated on the endosed drawing. These measures have generally been effective such that adivities in 2004 included only inspection, manual control (digging and disposal), and limited spraying of scattered occurrences of thistle (primarily Canadian and scotch thistle). Spraying occurred in September. Areas where weed control adivities occurred included the bottoms of the 720 Pit and Pit 1 reclaimed areas, the ridge on the west side of the 720 Pit, the margins of the shop area, along the main access road and the railroad right-of-way and in the vicinity of the shop building in the (970) 879-7888 • Fax (970) 879-7891 7880 C;nnnar Rhine nrivo • P(l Rm 77F77R • Steamhnat Snrinns_ CO 80477
