on the Wadge coal seam, which was previously surface mined in the portal area and on dip slopes to the
<br />south and southwest by TCC's sister company, Colorado Yampa Coal Company (CYCC). Existing surface
<br />disturbance along Foidel Creek at the main mine facility area consists of portals, surface support facilities,
<br />an office, low-quality coal stockpiles, a processing waste pile, conveyors, a tipple and batch weigh loadout
<br />facility, a ROM coal stockpile, two rock dust tanks, a explosives magazine, a rail spur, and sediment
<br />control ditches and ponds. A large area of the main facility area was within a disturbed area cal led the
<br />Area 2 pit within the CYCC permit No. C-81-071. Since the completion of mining associated with the No.
<br />C-81-071 permit, all pertinent facilities have been transferred to the Foidel Creek mine permit.
<br />The Life of Mine (LOM) permit revision (PR-Ol) application was approved in 1986 to expand the project
<br />into a 35-year mining operation utilizing both room and pillar and longwall techniques, with a peak
<br />production of approximately 3.5 million tons per yeaz. Upon approval of PR-Ol, the permit boundary
<br />encompassed 13, 114 acres and included both federal and privately owned coal. New and expanded
<br />surface facilities were required due to Permit Revision No. I. These facilities included; an
<br />office/bathhouse complex, new conveyor facilities, a transfer building, and 150,000 ton open coal stockpile
<br />and loadout facilities. Additionally, the Fish Creek Borehole dewatering site and associated treatment
<br />ponds were installed on Fish Creek, in TSN, R87W, Section 25. This borehole discharges treated water to
<br />Fish Creek at outfall 001 of CDPS Permit CO-0042161.
<br />Permit Revision No. 2, (PR-02), Southwest Mining District, was approved with stipulations on February
<br />17, 1993. PR-02 approved mining and subsidence in Panels 7, 8, and 9 ofthe SW mining district. Mining
<br />was completed in this area in 1996.
<br />Permit Revision No. 3, approved May 9,1996, allowed mining in the Eastem Mining District of Gateroads
<br />11 Right through 5 Right, construction of the Southwest Development Mains, and extraction of Longwall
<br />panels 9 Right through 7 Right. Approval of PR-03 expanded the LOM permit area to 22,694 acres.
<br />Extraction of 10,000,000 Tons/year was approved under Technical Revision No. 28, in 1997.
<br />Permit Revision No. 4 (PR-04), Eastern Mining District (southern area), was approved April 20, 1998.
<br />The revision approved continuation and expansion of mining in the southern portion of the EMD in
<br />portions of sections 21, 22, 23, 24, 27, 28, and 29 TSN R86W.
<br />Permit Revision No. 5 (PR-OS) was approved June 28, 2000 and provided for extension of mining into the
<br />Northern Mining District.
