Areas under reclamation and to be <br /> requested for release in this submittal are summarized in Table 4. <br /> Area 1, the Upper and Lower Mine Dump faces (13.46 acres) was reseeded and planted with saplings during <br /> 2003-2005. Area 2,the Upper Mine Bench(0.74 acres)was reseeded in 2004 and 2005. Area 4,the Research <br /> Mine Bench(2.7 acres)and Dump(1.5 acres),Area 10,the former Helo Pad(0.24 acres),and the Upper Bench <br /> Road(1.4 acres) and Lower Access Road(1.36 acres)areas of Area 13 were reseeded in the fall of 2005. The <br /> area below the toe of the Lower Mine Dump,which had been impacted from a debris flow off the Lower Dump <br /> in 2004,was reseeded and successfully revegetated in 2005 along with the upper portion of the Lower Access <br /> Road(about 0.2 acres). The lower portion of the Lower Access Road has not shown significant plant growth. <br /> This is partially due to damage from seasonal cattle grazing. This portion of the road was not reseeded as the <br /> road is now being used to access the Upper Manhole and monitor Well LWCW-IA on a regular basis. <br /> According to the 1985 annual report, Area 23, the Evaporation Pond and Pipeline (Retort Water Pipeline) <br /> consisted of a disturbed acreage of 14.9 acres, 5.1 acres of which was reclaimed before 1985,leaving 9.8 acres <br /> remaining to be reclaimed. Because the pond was not formally added to the permit until 2008, no reclaimed <br /> acreage has been released. It is assumed that the portion of Area 23 that has been reclaimed is limited to the <br /> ground surface above the buried and active Retort Water Pipeline. Most of the buried Retort Water Pipeline <br /> underlies the edge of the Logan Wash Road (Area 18), which will not be reclaimed. Note that future <br /> reclamation of the retort pipeline will involve removing the cast iron manhole covers at each clean-out location <br /> and grouting the pipe openings shut inside each vault followed by backfilling with clean inert and compacted <br /> fill. <br /> Area 13,Miscellaneous Access Roads (Table 2),includes a number of older roads that have been reclaimed.In <br /> this submittal,the Mine Bench and Portal roads referred to in Table 2 that are under reclamation include only <br /> the Upper Bench Road(1.4 acres). <br /> 2.3 Areas Not Under Reclamation <br /> Areas currently not expected to be submitted for reclamation release in the near future are the Upper Access <br /> Road(4.8 acres),the Lower Bench Road(Area 13, 1.5 acres),the Evaporation Pond Access Road(1.3 acres), <br /> AYeldel I_10142020.docx <br />
