The Permit includes two areas. An azea of underground mining and former surface support

truck to another area, where coal was off=loaded for transfer to a conveyor belt. This second area,
and a portion of the haul road to it, is referred to as the "loadout site" in this document. A
conveyor conveyed coal across the Roaring Fork River to a rail caz load out. The corridor of the
former conveyor belt from the center and to the west of the Roaring Fork River is also a part of
the loadout site. The corridor of the former conveyor belt from the center and east of the Roaring
Fork River, and the site of the rail loadout, a 29-acre area identified as the Diamond A parcel,
were previously reclaimed, released from bonding requirements, and removed from the permit in
1994.
The mine site is located on federal and private lands about seven (airline) miles southwest of
Cazbondale, within Pitkin County, Colorado. The eastern edge of the permit azea of the mine site
is located approximately eight and a half road miles from Cazbondale (from the intersection of
Garfield County Roads 10$ and 109 via Garfield County Road (GCR) 108 and Pitkin County
