<br />warranty.
<br />Areas Under Reclamation
<br />Areas in a state of reclamation (revegetation in progress) but not submitted for release to DRMS
<br />in the permit include Areas 1, 2, 3, 4, 10, and the 0.65 acre Soil Barrow Area, portions of Area
<br />13, and road Areas B2, B3, B7 and B8. Areas 1 through 4 include the Upper and Lower Mine
<br />Dumps (face areas), Upper Mine Bench, Lower Mine Bench, and the Research Mine Bench and
<br />Dump, respectively. Area 10 is the former Helo Pad. Area 13 is Miscellaneous Access Roads.
<br />Areas under reclamation at this time total approximately 21.8 acres. Area 11, the Guard Gate. and
<br />Area 18, Logan Wash Road will not be reclaimed.
<br />Area 1, the Upper and Lower Mine Dump faces (13.4 acres) were revegetated during 2003-2005.
<br />Area 2, the Upper Mine Bench (0.7 acres) was revegetated in 2004 and 2005. Area 3, the Lower
<br />Mine Bench (2.1 acres) is used for reclamation monitoring and is currently under natural
<br />revegetation status. Area 4, the Research Mine Bench (2.7 acres) and Dump (1.5 acres), Area 10,
<br />the former Helo Pad (0.2 acres), and the Upper Bench Road and Lower Access Road areas of
<br />Area 13 were revegetated in the fall of 2005. However, cattle grazing and dry conditions
<br />prevented the lower portion of the Lower Access Road from revegetating (approximately l .4
<br />acres). This was not reseeded as the road is now being used to access the Upper Manhole and
<br />monitor Well LWCW-IA on a regular basis.
<br />Area 23 is the Evaporation Pond and Pipeline. The portion of Area 23 that has been revegetated is
<br />limited to the retort water pipeline. The portion of Area 23 not revegetated or reclaimed is the
<br />Settling Pond and Evaporation Pond. According to the 1985 annual report, the original disturbed
<br />acreage of Area 23 was 14.9 acres, 5.1 acres of which was reclaimed before 1985, leaving 9.8
<br />acres remaining to be reclaimed. Because the pond was not formally added to the permit until
<br />2008, no reclaimed acreage has been released.
<br />Area 13, Miscellaneous Access Roads (Table 2), includes a number of older roads that have been
<br />reclaimed. In this report the Mine Bench and Portal roads referred to in Table 2 consist of the
<br />Lower Access Road (1.8 acres), Upper Access Road (4.8 acres), Upper Bench Road (1.4 acres not
<br />including bench), and Lower Bench Road (0.9 acres not including bench).
<br />The upper segment of the Lower Access Road, which had been impacted from a debris flow off
<br />the Lower Dump in 2004, was successfully revegetated in 2005, whereas the lower segment of
<br />the Lower Access Road (approximately 1.4 acres) has not shown significant plant growth. This is
<br />partially due to damage from seasonal cattle grazing.
