C- 1992 -080 File 30 -Jan -2014 Permit Acreages Page 2 of 4 Carbon Junction Mine Permit Area Chronology A thorough review of the permitting history identified the various revisions under which the acreage of the permit area was revised. These are outlined here, in chronological order: MR -02 (Mar - 1994): For this revision, a formal survey (by a licensed surveyor) of the permit boundary was conducted. The result was 33.06 acres for the Ewing Mesa gravel pit, which was fully contained within the Carbon Junction coal permit boundary of 253.46 acres. The difference between these two areas resulted in 220.40 acres being the responsibility of the coal mine. SL -01 (Apr - 1997): With this bond release, 18.34 acres was excised from the northwest corner of the coal permit boundary. Approximately 1.0 acres had been disturbed for the storage of explosives, and was effectively granted Phases I, II, and III bond release. The net permit area was reduced to (220.40 — 18.34) = 202.06 acres. TR -07 (Jun - 1997): Under this revision, 12.17 acres of undisturbed ground were excised from the western margin of the permit area, resulting in a new total of (202.06 — 12.17) = 189.89 acres. TR -10 (Jun 2001): This revision excised 7.87 undisturbed acres from the eastern side of the coal permit for inclusion in the new Ewing Mesa Pit No. 2 being permitted adjacent to Pit No. 1. The resultant coal permit acreage was (189.89 — 7.87) = 182.02 acres. TR -12 (Jul - 2004): With this revision, the Ewing Mesa No. 1 Pit absorbed 21.59 acres from the coal mine, 14.31 acres of which had been disturbed -- the South Pit and Joint Use Areas. A 2.9- acre area was added to the western boundary for the permanent diversion disturbance. The net area for the coal permit was reduced to (182.02 — 21.59 + 2.90) = 163.33 acres. AR -01 (May - 2005): The Ewing Mesa gravel permit acreage was adjusted under AR -01 to exclude 1.01 acres of the coal permit equipment storage area that had been incorporated in error. This change increased the coal permit area by the same amount, resulting in a permit area of (163.33 + 1.01) = 164.34 acres. This is the current acreage of the Carbon Junction Mine, Permit No. C-1992-080. Bond Release History of the Carbon Junction Mine As noted above, SL -01 removed 18.34 acres from the permit area in Apr -1997. Phase I, II, and III bond release was granted for the 1.0 acres that had been disturbed. SL -02 transferred 21.59 acres of the coal permit into the gravel permit area in Jul -2005. The affected areas included the South Pit and the Joint Use Area. As reported beginning with the 2008 Annual Reclamation Report, 14.31 acres of the transferred area were disturbed; this acreage was granted Phase 1, II and III bond release. With SL -03, the Division approved Phase I bond release for backfilling and grading accomplished in 2006 at the North Pit, North Pit Haul Road, Previously Reclaimed Spoils Area
